Description

An adulterous matter treatment device with enhanced contamination filtration and sand dehydration effect {Adulteration disposal equipment advanced filtering and dehydrating performance}

The present invention relates to a foreign matter treatment machine with improved effect of filtration and sand dewatering, and more particularly, to a foreign matter treatment machine for filtering and dewatering solids in a liquid waste treatment process such as manure, sewage, livestock manure, and food waste. It is a machine related field.

In general, a contaminant treatment device is a system device in which several unit machines are combined in stages. It is a device that separates, filters, dehydrates, and processes contaminants, which are organic components, and inorganic sand. applied to the treatment of

First of all, if we look at the impurities treatment function in the contaminant treatment machine as described above, in the case of excreta or livestock excreta treatment, the manure that has finished the primary treatment in the manure treatment process is put into the sewage treatment process, and the so-called manure is secondarily treated together with the sewage. In the sewage-linked treatment system, there is no need to filter the fine contaminants in the inflow stage because the micro-contaminants are resolved in the subsequent linkage treatment.

For example, Patent Document 1, which is a prior art, relates to a contaminant treatment device (hereinafter referred to as “Background Art 1”) that contributes to an increase in digestion efficiency, and is a contaminant treatment device in the filtration and dehydration treatment of manure, sewage, livestock manure, food waste, etc. It relates to a contaminant treatment machine that extracts beneficial bio-nutrients for improving digestion efficiency and at the same time improves the dehydration performance of contaminants by ejecting water through a hollow shaft to contaminants introduced into the screw press of Filter contaminants with only one by applying

However, since the filtration limit size of the rotary screen included in the background art 1 is usually 5 to 6 mm, conversely, it can be seen that contaminants of this size are not filtered and passed to the sewage treatment system as treated water. In this case, problems such as jamming, deposition, sedimentation, and scale generation in the piping line may occur depending on various conditions such as the inclination angle or bend state of the connecting pipe, the distance, the piping member such as a valve, and the aging condition.

In addition, there is Patent Document 2, a foreign matter treatment machine using a wedge-rod screen (hereinafter referred to as background art 2), which was created to solve this problem. This means can filter solid substances of a size smaller than 5-6 mm by applying only a wedge-bar screen, which has improved contaminant filtration performance than the rotary screen of the background art 1 above. However, this background art 2 also has a limit that is not sufficient for the treatment of raw manure contaminants. As indicated in the 'Effect of the Invention' of Background Art 2, “It is possible to filter most of the waste liquid except for some waste liquids such as so-called malignant live manure, regardless of the shape or composition of the solid, with one wedge screen. As seen in “……”, it can be seen that raw manure is excluded from the treatment target.

In addition, when looking at the sand treatment function, if a small amount of sand flows into the treatment process over a long period of time, it is deposited at the bottom of various tanks to reduce the actual tank capacity, and causes wear and tear of various devices and pumps, damage, and closure of pipes. will cause problems In particular, the work to remove the sediment accumulated on the bottom of the tank must be done while the normal process is suspended for a certain period of time, which may cause a significant setback in the overall treatment process.

In addition, the conventional contaminant treatment machine as described above mainly utilizes a general-purpose horizontal screw decorator, and has a problem in that it does not match the specific gravity, viscosity, surface tension, and properties of contaminants, which are target materials, and thus has a limitation in performance.

Therefore, the present invention utilizes the water jet effect of the screw press of the background art 1, and also utilizes the wedge bar screen of the background art 2, but overcomes the limitation of raw manure treatment impossibility, and in addition to this, the sand dehydration effect of the screw decanter By promoting

Republic of Korea Patent Publication No. 10-2088362 Republic of Korea Patent Publication No. 10-1729262

The function of the foreign matter treatment machine can be divided into a foreign matter treatment function and a sand treatment function as described above. It is further divided into four detailed functions, such as a foreign matter filtering function, a foreign matter dewatering function, and a sand filtering function and a sand dewatering function.

Looking at the unit devices generally applied to each function, first, the rotary screen and the wedge bar micro screen have been mainly used sequential filtration method by particle size for the contaminant filtering function, and a screw press is applied for the contaminant dehydration function. A cyclone classifier is used for filtration of sand, and a sludge decanter is applied for sand dewatering.

Substituting the above four detailed functions into the present invention, first, the contaminant filtering function replaces the conventional filtration method using two screens such as the rotary screen and the micro contaminant screen, which has been followed for a long time, and is a wedge bar at the initial stage. By applying the above background technology 2 to which only one drum screen 100 is applied, but by lowering the installation angle, it is possible to filter even raw manure, which is impossible in background technology 2, thereby increasing the utility and economic feasibility of the foreign matter filtering function. Second, foreign matter dehydration function With respect to this background technology 1, which extracts microbial nutrients using water sprayed inside the shaft of the screw press 400 and enhances the dehydration effect, is applied, and thirdly, each part of the cyclone 200 for sand filtering function The effect of the sand filtering function can be improved by finding the dimensional ratio and cone angle of Considering that there is a limit to this, it is intended to improve the sediment processing performance by partial shape change and addition of members.

Here, the effect of the wedge bar drum screen 100 serving as the first function of filtering contaminants will be described.

Conventional drum filters in which the unit filter pores are circular have a negative effect of reducing the actual passage area of the filter pores due to agglomeration due to the influence of surface tension and viscosity acting in all directions of each filter hole. On the other hand, since the filtering hole of the wedge bar drum screen 100 is a long slit, the force to prevent filtration acts only in two directions, so the influence of the agglomeration that prevents passage through the gap is greatly reduced, and the inner narrowing between the wedge bars 111 It is not easily clogged during the filtration process because the external light gap is a filtration passage.

The most essential element is that the filtering drum 110 is installed with a slight inclination, so there is no internal protrusion such as a screw for transporting the filtrate or an element that interferes with the progress of the foreign matter, so the foreign matter is not disturbed and the filtering drum ( 110) Inside, just like snowflakes rolling in a snowfield, even fine contaminants smaller than the crevice gradually agglomerate together to form a long lump of rice cake-like shape, which exerts the effect of rolling out the inside of the cylinder. It has the effect of preventing clogging.

In addition, a washing device including a washing water tank 150, a washing pump 151, a washing water pipe 152, a washing nozzle 153, etc. is provided on the outer circumferential surface of the filtering drum 110 to provide a wedge bar 111 filter body outer circumferential surface to prevent contamination of Since the washing device is of a reciprocating type, while reducing the number of washing nozzles 153, it has the same washing effect as the fixed type, so that a sufficient washing effect can be achieved even with a small amount of washing water.

Combined with the above various effects, it exhibits a filtration effect of fine contaminants that exceeds the effect of a rotary screen with a filtration level of 5 to 6 mm. Although it differs depending on the difference in solid components, properties, concentration, and amount of treatment, the effect of filtering 1-2 mm in size from purified sludge and livestock manure as well as raw manure with high processing difficulty appears. If the size of the filtered solids is this size, the effect that is sufficiently applicable in the sewage-linked treatment system mentioned above can be exerted without any further filtration process.

As described above, the fact that a single wedge bar drum screen 100 can filter even high-level raw manure is greatly influenced by the inclination angle of the drum. In the present invention, since the inclination angle of the filtering drum 110 is 1 degree or less (the actual application angle is about 0.5 degree), which is almost horizontal, the time for solids to stay inside the drum becomes longer, which is the effect of having a sufficient chance of draining water. will be. This is an inclination angle of 3 degrees or less (actual application angle is 2.5 degrees), and the flow inside the drum of the object to be treated is fast and the water does not have enough time to escape, so the wedge rod of Background Technology 2 cannot show the proper filtration effect. It is the effect that contrasts with the screen. The so-called benign waste liquid, which is relatively easy to filter, can be filtered even at an inclination angle of 2.5 degrees (3 degrees or less), but in the case of raw manure, which is a malignant waste liquid, the effect of the inclination angle is significant, and it is almost 1/5 of the conventional angle. It can be seen that the effect of reducing the inclination angle of the present invention is that the filtering effect appears only when a gentle inclination angle close to the horizontal is obtained.

As mentioned in the previous 'technology background of the invention', unlike the impossibility of filtration of raw manure indicated in Background Art 2, in the present invention, even raw manure can be sufficiently filtered, and thus, it has a performance differentiated from that of Background Art 2.

If the treatment object of the background art 2 is excluding live manure, the treatment object of the present invention includes live manure. That is, it can be seen that the purpose of the invention is different from the background art 2 and the present invention in relation to the contaminant filtration treatment. As described above, the contaminant filtration method of the present invention that lowers the inclination angle of the wedge bar drum screen, which had a function of filtering fine contaminants in the later stage of the conventional rotary screen, and completes the filtering function up to the range of contaminants in live manure with this alone It can be an appropriate model especially for sewage-linked treatment systems by demonstrating its effectiveness and economic feasibility in filtration of contaminants.

On the other hand, however, the following question may arise here. In relation to the filtration of contaminants of raw manure, even when the remaining fine contaminants are secondarily filtered with a wedge bar drum screen after primary filtering of medium and large contaminants with a size of 5 to 6 mm with a conventional rotary screen, raw manure is filtered more than other contaminants. Recalling the difficult point, it would seem that it does not make sense to filter all contaminants, including 5-6 mm or larger, at a sufficient level at an early stage from the beginning. The key to solving this question is the agglomeration effect and the mopping effect.

To elaborate on the agglomeration and mopping effect described above, the screen for filtering by flowing into the inside of the rotating filter drum is usually installed horizontally. For this reason, there must be an intermittent or continuous screw, or any kind of protrusion that pushes the inner material forward in order to transport the inner material. This member protruding from the inner circumferential surface of the drum is beneficial to the transport of foreign matter, but it is a factor to disturb the aggregation of foreign matter. On the other hand, the wedge bar drum screen 100 of the present invention transports contaminants using only a slight inclination without protruding members inside the drum.

Looking at the movement of contaminants inside the filtering drum 110 of the wedge bar drum screen 100 of the present invention, when the water is drained to some extent after the initial stage of filtration, the contaminants begin to agglomerate around the large contaminants and form into a single mass. . This has a shape similar to that of rolling a long rice cake by putting it in the filtering drum 110 in the longitudinal direction. This contaminant lump is rotated slightly upward from the lower end of the cross section of the filtering drum 110 and continues the rotational motion at the rising point and the orbital motion slowly advancing toward the exit side. This acts as if a long mop is put into the filtering drum 110 and the inner surface is rolled and wiped while collecting contaminants inside the drum and connecting them for a long time to escape. In this way, even fine contaminants are merged into one to show the effect of filtering. By continuously wiping the inner surface, the filtration gap is clean and the water draining effect is improved.

The above is the agglomeration effect and mopping effect of the assembled grid-type drum screen 100 of the present invention. In the above, when the screen is applied as a secondary filter and only the fine impurities remaining from the primary filtration are introduced and the case where large and small contaminants are introduced together by applying to the first step as in the present invention, it is applied to the secondary filtration step Therefore, in the case of filtering only fine substances, the mopping effect is insufficient due to the long time for contaminants to aggregate into one, whereas if large contaminants are added together, the mopping effect appears faster and the mopping strength is increased. For this reason, as in the present invention, it is possible to complete the filtering of contaminants with one wedge bar drum screen 100 as in the present invention. It is possible to break the stereotype recognized as a long-standing common sense that contaminant filtration must go through at least two steps.

As described above, the present invention exhibits more than expected performance in the foreign matter filtering function due to the two effects, such as the contaminant aggregation effect and the mopping effect, inside the filtration drum.

Next, the fourth function, the effect of improving the screw decanter of sand dewatering, is explained.

The screw decanter 300 of the present invention has the effect of increasing the throughput by increasing the water draining rate compared to the conventional circular orifice 314 by applying the long hole orifice 315 as a means of not skipping.

In addition, the lowest point of the long hole orifice 315 can be moved to the center side by using the orifice control insertion rod 3161 or the orifice control insertion plate 317 of the present invention, thereby facilitating the dewatering rate of the sand and the purification degree of the desorbent. There is an effect that can be adjusted.

In addition, the screw decanter 300 of the present invention forms the long hole orifice 315 at a position lower than the lowest design value, and selectively during trial operation or use, an orifice control insert rod 3161 or an orifice adjustment insert plate 317 of an appropriate size. ), since the method of raising and matching the lowest point is applied, there is an effect that the width of the setting of the lowest point of the long hole orifice 315 is widened.

To summarize the above effects, the wedge bar drum screen 100, which filters fine impurities at the rear of the conventional foreign matter treatment machine, is arranged in the initial stage, but the inclination angle is very gently installed from less than 3 degrees to less than 1 degree, so that only one It has the effect of filtering even impurities from raw manure with only a unit device with a contaminant filtration function, and increases the throughput by changing the shape and position of the orifice through which the liquid separated from the sand is discharged, and controls the purification degree of the separated liquid and the moisture of the dewatered sand. Through the above two effects, such as the improvement effect of the screw decanter that allows

As used in the present invention, the term ‘foreign matter’ of ‘contaminant treatment machine’ refers to various solid substances to be removed. These contaminants are divided into organic combustible materials such as textiles, papers, plastics, wood, and food, and inorganic non-combustible materials such as soil and metal represented by sand. By the way, only the former organic material is also commonly referred to as a contaminant here. Accordingly, 'foreign matter' in the 'foreign matter processor' refers to contaminants in a broad sense for all solid matter such as organic contaminants and inorganic sand, but in the present invention, 'contaminants', 'filtering contaminants', 'dehydration of contaminants', ' When used independently from the prefix of 'processor' such as 'discharge of contaminants', it shall indicate 'organic contaminants' in a narrow sense that refers only to organic solids excluding sand.

Hereinafter, with reference to the accompanying drawings, a first embodiment of the impurities filtration and sand dewatering effect is enhanced according to the present invention will be described in detail.

The present invention is a device consisting of a system configuration in which several unit devices each having separate functions are combined and operated step by step, and the wedge bar drum screen 100, the transfer tank 140, the cyclone 200, the screw decanter ( 300) includes a screw press 400 and a carry-out conveyor 600.

Described by process, first, the wedge bar drum screen 100 is applied as a contaminant filtering process. In the contaminant filtration process, a predetermined gap is formed in a long and thin wedge bar 111 having a wedge shape in the longitudinal section, and the predetermined gap is gradually widened from the inner circumferential surface to the outer circumferential surface. (110) is made.

At this time, it is installed at a slight inclination (less than 1 degree) from the horizontal, and the material to be treated is put into the center of the high side and rotated at a low speed (20 rpm or less) so that the liquid component is transferred to the lower side opposite to the wedge bar (111). ) and the solid material larger than the gap is filtered and collected at the lower end of the filtering drum 110 to be descended.

There is a washing line composed of a washing water tank 150, a washing pump 151, a washing water pipe 152, and a washing nozzle 153, and the washing water pipe 152 reciprocates in a certain range on the outer circumferential surface of the filtering drum. It is designed to prevent contamination of the filter surface by spraying it.

It is configured to smoothly filter contaminants through the external expansion effect of the cross section of the filtration passage, the aggregation effect, the mopping effect, and the reciprocating washing effect. The connection method is usually

Here, the filtered contaminants are introduced into the contaminant dewatering process and the screw press 400 , and the filtrate is collected in the lower transfer tank 140 and introduced into the sand filtration process through the transfer pump 141 .

The next step utilizes the cyclone 200 as a sand filtration process. The cyclone 200 is a generic name for a cyclone classifier, and the filtrate flowing into the transfer pump 141 is introduced into the inlet 210 , and the sand component is a sand outlet located below the cyclone 200 . Discharge to 220, and the filtrate performs a solid-liquid instantaneous separation function that discharges the filtrate to the filtrate outlet 230 located at the upper portion of the cyclone (200).

More specifically, the cyclone 200 has a frustum that narrows downwardly extending from the lower portion of the vertical cylinder, and the sand outlet 220 is provided at the lower end of the truncated cone. Although the upper surface of the cyclone 200 is sealed, the filtrate outlet 230 formed of a circular tube in the center protrudes vertically. The filtrate outlet 230 enters a predetermined depth into the cylinder, and the inlet 210 is attached to the cylindrical outer peripheral surface of the cyclone 200 in a tangential direction of the cylinder.

Looking at the operation of the cyclone 200, the high flow introduced into the inlet 210 of the cyclone 200 from the transfer tank 140 under the wedge bar drum screen 100 through the transfer pump 141 · A strong centrifugal force is generated while the liquid mixture rotates and descends sequentially on the inner peripheral surface of the cylinder and the truncated cone. At this time, the relatively heavy sand component is in close contact with the inner circumferential surface and rotates down. It is discharged to the sand outlet 220 at the bottom, and the relatively light liquid and fine solid material become a reverse flow that fills the low pressure part formed inside the cone and rises to the upper part. Since it is discharged to the filtrate outlet 230, the sand component and the liquid component are instantly and continuously separated from the bottom and the top, respectively.

The next step is the screw decanter 300 of the sand dewatering process, which is a core unit device of the present invention to dewater by introducing the sand component discharged from the sand outlet 220 at the lower part of the cyclone 200 .

The principle of the screw teccanter 300 is to maximize the centrifugal effect by using high-speed rotation to increase the sedimentation speed of the solids so that the solids are rapidly driven away from the center, and to separate the solids and the separated desorbent using the rotation difference of the screw. each to be discharged separately.

The screw decanter 300 is an external bowl 310, an internal screw 320, an inlet pipe 330, a desorbent outlet 340, a solid outlet 350, a bed 360, a cover 370 and an electric motor ( 380).

First, the screw decanter 300 of the present invention is formed in a form in which a horizontally placed cylindrical cylinder 311 and a conical cylinder 312 whose diameter gradually decreases from one side of the cylindrical cylinder 311 to the outside are extended, It is installed concentrically on the inside of the external bowl 310 and the external bowl 310 in which the inflow liquid is accommodated therein, and includes an internal screw 320 having a predetermined gap with the inner peripheral surface of the external bowl 310.

In addition, the present invention includes an inner copper pulley 324 and an outer copper pulley 319 respectively mounted on the inner copper screw 320 and the outer copper bowl 310 and positioned adjacent to each other, the inner copper pulley 324 and the outer copper pulley 319 is connected to one electric motor 380 . A driving timing pulley 381) is mounted on the electric motor 380, and the driving timing pulley 381 is connected to the inner pulley 324 and the outer pulley 319 by a timing belt 382, respectively. Accordingly, by connecting the timing belt 382 to the inner pulley 324 and the outer pulley 319 , a rotation difference is generated between the inner screw 320 and the outer bowl 310 . The rotation difference is made by adjusting the number of teeth of the three timing pulleys (319, 324, 381).

Therefore, the inner screw 320 and the outer bowl 310 have a rotation difference with each other so that they can be rotated at high speed in the same direction, and the sand component contained in the contaminants is dehydrated by centrifugal force due to the rotation and separated and discharged. function.

In addition, in the present invention, the inner screw 320 corresponding to the cylindrical cylinder 311 side ejects the ejection chamber 322 and the inflow of the ejection chamber 322 into the cylindrical cylinder 311. A pipe 323 is included, and the jet pipe 323 has a plurality of jet holes 323a formed on the main surface of the jet pipe 323 .

In addition, an inflow hollow shaft 321 is installed in the center of the jetting chamber 322 , and the inflow hollow shaft 321 extends and protrudes to the outside. At this time, the inlet pipe 330 provided with the inlet 331 is fixed to the inlet pipe holder 332 while maintaining a predetermined gap inside the inlet hollow shaft 321 .

In addition, the present invention provides a plurality of interaxial bearings 325 positioned in the space between the shafts of the outer bowl 310 and the inner screw 320 and a plurality of fixed bearings for fixing the inner screw 320 to the bed 360 ( 326 ), and the cover 370 surrounding the entire rotating body including the outer bowl 310 and the inner screw 320 is fixed to the bed 360 .

In addition, the cylindrical cylinder 311 includes a side plate 313 installed on the side of the cylindrical cylinder 311, and the side plate 313 is the outer bowl 310 so that the talismant liquid can be discharged. and a long hole orifice 315 formed at the same distance from the center of the side plate 313 . Of course, the side plate 313 is formed as a circular plate in the same way as the cylindrical cylinder 311 .

In other words, the solids dehydrated in the external bowl 310 are discharged to the end of the conical cylinder 312 , and the desorbed liquid is discharged to the long hole orifice 315 .

On the other hand, when explaining the operation of the screw decanter 300 included in the contaminant treatment device according to the present invention, the solid-liquid mixture passes through the inlet 331 and the inlet hollow shaft 321 inside the inlet pipe 330 ) is introduced into The solid-liquid mixture introduced into the inlet pipe 330 enters the ejection chamber 322 , and then is ejected into the cylindrical cylinder 311 through the ejection hole 323a. The ejected solid-liquid mixture comes close to the inner peripheral surface of the outer bowl 310 under the action of strong centrifugal force due to high-speed rotation, and a pipe-shaped horizontal water tube (annular liquid, 環狀液) having a certain distance (or water level) from the center. ) is formed.

At this time, the solid material having a relatively large specific gravity is brought into close contact with the outer circumferential surface of the annular solution, that is, the inner circumferential surface of the outer bowl 310 . When the inflow action of the solid-liquid mixture continues, the water level rises, and the water level approaches the axial center of the side plate 313 from the outermost side of the long hole orifice 315 formed in the side plate 313. When this occurs, the leaching liquid overflows into the long hole orifice 315 and is discharged to the outside through the eliminative liquid outlet 340 .

In addition, the solid material in close contact with the inner circumferential surface of the outer bowl 310 is pushed out toward the conical cylinder 312 side by the transfer action of the inner copper screw 320 to escape from the water surface and to the beach.

In the process in which the solid is moved by the inner moving screw 320 on the beach, the liquid contained in the solid is detached from the solid by centrifugal force. The desorbed liquid is transported to the cylindrical cylinder 311 in which the centrifugal force acts larger through the gap between the inner screw 320 and the conical cylinder 312 . The solids pass through the beach and the dehydration action continues, and collects to the solids outlet 350 through the solids outlet blades 312a at the end of the conical cylinder 312 and is discharged to the outside.

In addition, the long hole orifice 315 is a water drain hole, which serves as a weir through which the talismant overflows, and is formed in a long hole type, compared to the conventional background art orifice 314 having a circular shape. .

When the orifice 314, which is a conventional background art, is formed in a circular shape, the width of the non-overflowing weir is narrow, and when the inflow amount of the talismant increases, the amount of liquid flowing out is small compared to the rising water level, so that the high water level is maintained. At this time, due to the high water level, the inner beach of the conical cylinder 312 is shortened, and due to this, the solids dewatering time at the beach is also shortened, so that sufficient dehydration of the solids is not made, so the inflow of the desorbent is limited.

In contrast to this, the long hole orifice 315 of the screw decanter 300 included in the contaminant treatment device of the present invention has a long hole shape, so even if the inflow of the desorbent rapidly increases, the area of the long hole orifice 315 is wide and water Since the draining speed is fast, the rapid rise of the water level can be prevented, and since the change of the beach is small, it does not interfere with the dehydration of solids, so that the throughput is increased under the same conditions and the ability to respond to the instantaneous change of the leaching solution is improved.

In addition, the screw decanter 300 included in the present invention is limited to contaminants, and the material to be treated of the screw decanter 300 is a rather large amount of fine organic suspended matter in addition to sand is evenly distributed and distributed throughout. As agglomerated sewage, since the viscosity, surface tension, cohesive force, and adhesion force are greater than that of fresh water, the draining effect in a narrow space such as the circular orifice 314 of the background art is not good. On the other hand, the long hole orifice 315 of the present invention is formed in a long hole type, and the water draining effect is superior to that of the circular orifice 314 by increasing the no-over width. As in the present invention, the orifice of the screw decanter 300, which treats sewage with high surface tension and viscosity, as in the contaminant treatment machine of the present invention, has a large single non-overturning width like the long hole orifice 315, not the sum of its entire area, so that the water draining effect will get better

Accordingly, in the screw decanter of the present invention, by applying the long hole orifice 315, the water draining width of a single no-pass is widened, the water draining speed is increased, the change of the beach is reduced, and the sand dewatering effect is increased.

In addition, since the dewatering material of the screw decanter 300 included in the contaminant treatment device of the present invention is sand (true specific gravity 2.65) having a relatively larger specific gravity than the liquid, it is separated by the specific gravity difference inside the outer bowl 310 speed is very fast Accordingly, there is an advantageous condition that sand is not easily discharged even from the long hole orifice 315, which has a high non-overturning speed, because sand is strongly adhered from the center to the outside almost at the same time as the inflow of the mixture.

In addition, the long hole orifice 315 has the effect that the length of the cylindrical cylinder 311 of the outer bowl 310 can be shortened, or can be eliminated in some cases.

More specifically, the internal volume of the cylindrical cylinder 311 is related to the residence time of the treated material, that is, the amount of treatment. Since it is discharged in a short time and the water level does not rise easily, the beach is maintained and does not interfere with sand dewatering. Therefore, it is possible to reduce the length of the cylindrical cylinder 311 in relation to the residence time and throughput.

In addition, referring to FIG. 8 , the long hole orifice 315 has a shape similar to that of combining two adjacent circular orifices 314 into one, and the two points on the circumference farthest from the axial center of the side plate 313 are arced. A tangentially connected main line is referred to as an orifice outer perimeter line 315a, and a main line tangentially connecting two points on a circumference closest to the axial center of the side plate 313 with an arc is referred to as an orifice inner circumferential line 315b.

The long hole orifice 315 is formed in a shape consisting of the orifice outer circumferential line 315a and the orifice inner circumferential line 315b, and the orifice outer circumferential line 315a and the orifice inner circumferential line 315b are the side plates ( 313) becomes part of the circumference of the concentric circle.

In addition, the long hole orifice 315 is located on the same circumference from the axial center of the side plate 313, but is formed in plurality at regular intervals. The long hole orifice 315 is preferably formed of, for example, three or four. Of course, the long hole orifice 315 may be formed in various numbers depending on the size of the side plate 313 and the like.

In summary, in the present invention, due to the long hole orifice 315 formed in the side plate 313 of the screw decanter 300, the sedimentation treatment performance is further improved by increasing the draining rate at which the desorbing liquid separated from the solid material overflows. can be promoted

The screw press 400 of the contaminant dewatering process of the next stage is a device for dewatering by receiving the filter material of the wedge bar drum screen 100, and is installed horizontally and has a perforated main surface that provides a cylindrical inner space. ), is rotatably installed inside the cylinder 420, rotates by external power, and introduced into the cylinder 420 through an inlet chute 410 formed by partially incising an upper main surface of one side of the cylinder 420 A screw 440 provided on the rotating shaft 430 for transporting contaminants, and a cross-sectional area control tool 450 for gradually reducing the cross-sectional area of the space between the shaft 430 and the cylinder 420 to generate a compressive force on the passing material ) is included.

The screw press 400 uses a part of the shaft 430 as a hollow shaft, and the jetted water that has entered the hollow shaft is jetted onto the filter material that has entered the inflow chute 410, and the filtered material before being introduced into the compression space. microbial nutrients are extracted in advance. At this time, the remaining material is sent to the compression section to be dehydrated with the screw 440 and the cross-sectional area control hole 450 , so that the desorbed liquid is discharged through the dehydration hole 421 and the dehydrated contaminants are discharged through the contaminants outlet 470 . .

More specifically, the screw press 400 is horizontally fixed and installed, and the main surface of the upper part of one side of the circular cylinder 420 having a plurality of dewatering holes 421 on the main surface is partially cut to the inlet chute 410 of contaminants. And the cylinder 420 is to rotate the screw shaft 430 concentric with the cylinder with an external power to advance the introduced contaminants and dehydrate.

In addition, using the inside of the cylinder 420 in the lower part of the inlet chute 410 as a contaminant transport section, and the cross-sectional area control member 450 having a reverse cone shape having a bearing inside, a gradual compression force is applied to the passing material. The next zone constructed is the compression zone.

The contaminants that have passed the transport section are dehydrated under the action of a compression force that gradually increases while passing through the compression section, and the desorbed liquid exits through the dehydration hole 421 on the main surface of the cylinder 420 . The leaching liquid is collected in the eliminator tank 460 and comes out through the eliminator outlet 461 and is discharged to the outside through the treated water outlet 700 . The dehydrated contaminants are discharged through the contaminants outlet 470 on the side of the cylinder 420 opposite the inlet side.

At this time, the shaft 430 located below the inlet chute 410 , that is, in the transfer zone, is used as a hollow shaft, and the inner space is used as a water supply tank 480 , and the water spray tank is passed through the rotary joint 510 from the water spray pump 500 . The jetted water introduced into (480) is sprayed into the transport space of contaminants through the watering hole 481 provided in the watering tank 480, hitting and extracting the microbial nutrients contained in the contaminants, and this is used in the subsequent digestion process. By allowing it to flow in, it contributes to the improvement of digestion efficiency and at the same time creates the effect of one stone and two birds, which also improves the dehydration performance of contaminants.

Here, in order to minimize the amount of water sprayed in the upward direction, no matter which part of the water spray tank 480 that rotates to the upper side comes to the upper side, it is always on the upper inner peripheral surface (about 1/3 of the circumference) of the water spray tank 480 . A buoy 490 that suppresses the ejection of hitting water to the upper portion by floating close is provided inside the water sprinkling tank. The constant flotation action of this buoy 490 is to prevent this because the ejection water can spring out like a fountain in the upper direction, and the hitting effect can be reduced.

It is preferable that the water spray tank 520 has a heater 521 therein to spray hot water. In particular, in winter, the hot water is beneficial in extracting fine substances and preventing freezing.

As a material discharged to the outside through the above entire process, the filtrate discharged to the upper filtrate outlet of the cyclone 200, the desorbent discharged to the desorbent outlet 340 of the screw decanter 300, and the desorbent of the screw press 400 The desorbed liquid discharged to the outlet 461 is combined with the treated water outlet 700 and usually enters the subsequent fire extinguishing process line, and the dehydrated sand component of the screw decanter 300 exiting the solid matter outlet 350 is generally inclined conveyor 390 ), it is carried out on the carry-out conveyor 600 along with the dehydrated contaminants of the screw press 400 coming out of the contaminants outlet 470 and carried out.

Hereinafter, with reference to the accompanying drawings, a second embodiment of the impurities filtration and sand dewatering effect is enhanced according to the present invention will be described in detail.

This embodiment is a configuration in which the screw decanter 300, the long hole orifice 315 in the 'first embodiment' blocks a certain range of the outer periphery space with the orifice adjusting member 316 to change the lowest point without skipping, and the rest of the configuration is the same as that of the first embodiment, so the description of the embodiment is referred to.

First, looking at the phenomenon according to the position of the lowest point of the orifice 314, which is a conventional background art, if the lowest point of the orifice 314 is too low, the thickness of the annular solution becomes thin, so the possibility that solid material is generally contained in the leaching solution increases. will do In this case, the low lowest point means that the lowest point of the orifice 314 is biased outward from the center of the side plate 313 .

Accordingly, the degree of purification of the leaching liquid may be lowered, so that the processing of a large amount is limited, while the reflection becomes longer, so that the sand dewatering effect is increased.

Conversely, when the lowest point of the orifice 314 is high, the opposite phenomenon occurs. In this case, the high lowest point means that the lowest point of the orifice 314 is biased toward the inside of the side plate 313 .

In the present invention, the impurity filtration and sand dewatering effect of the contaminant treatment device with enhanced effects of the treatment target material, such as spatial and temporal changes, are large, and the contaminant treatment device, which occupies a part of the waste liquid treatment process, is the overall treatment method even during use. Depending on the change, the contents of the substances flowing into the contaminant treatment unit are also changed. As such, the screw decanter included in the contaminant treatment device may have to adjust the sand dewatering level and the degree of purification of the desorbing liquid during installation and use.

Accordingly, the present invention proposes a method for changing the lowest point of the long hole orifice 315 while using the screw rectifier 300 included in the contaminant treatment device.

More specifically, by blocking the orifice outer circumferential line 315a of the long hole orifice 315 with the orifice adjusting member 316, the lowest point of the long hole orifice 315 can be moved to the center side of the side plate 313 This is to have the effect of easily adapting to changes in the inflow amount and dehydration rate, etc.

The conventional means for changing the height of the lowest point of the orifice 314 is generally used in a way that the blocking plate is in surface contact with the side plate 313, and the method of blocking the blocking plate from being in surface contact on a plane is a simple method, but Since the tally liquid overflowing by the orifice 314 without skipping is clogged with the diaphragm, there is a problem in that the height of the weir becomes a double step-by-step skipping.

In this case, a part of fine sand or fine contaminants with relatively large specific gravity among the materials that have crossed the primary weir is continuously subjected to centrifugal force to move toward the larger turning radius, so it cannot cross the smaller radius of the secondary weir. There was a problem of staying in the space between the jumps. Of course, the primary weir may refer to the orifice 314, and the secondary weir may refer to the blocking plate. Accordingly, there is a problem of abrasion of the diaphragm and the orifice 314, and a problem of impairing the stability of solid-liquid separation due to the pocket phenomenon vortex.

In contrast to this, in the second embodiment of the present invention, when the orifice adjusting member 316 is used, only the height at which the eliminator overflows the long hole orifice 315 is changed, and the long hole that is the distance through which the eliminator passes through and exits. The length of the orifice 315 is the same without exceeding the thickness of the side plate 313 . In addition, there is no change in the width of the long hole orifice 315, and above all, since it has a structure without double walls such as the primary and secondary weirs, it can be said that there is no hydrodynamic problem or other side effects.

9 to 12, when the configuration of the second embodiment is described in detail, the screw teccanter 300 of the foreign matter treatment machine in which the foreign matter filtration and sand dehydration effect according to the present invention is enhanced is the long hole orifice ( In 315), it further includes an orifice adjusting member 316 that is provided to adjust the position at which the leaching liquid overflows.

The orifice control member 316 is one side of the orifice control insertion bar 3161 so that it can be assembled to the orifice control insertion rod 3161 inserted into the outer circumferential surface of the long hole orifice 315 and the connection plate 318 to be described later. Including an assembly plate 3162 connected in the vertical direction.

That is, when the orifice adjusting member 316 is viewed from the side, the cross section of the orifice adjusting member 316 is formed in an overall shape such as a 'L'.

In addition, the orifice control insertion bar 3161 is formed to have the same width as the thickness of the side plate 313 so that only the height at which the talismant overflows the long hole orifice 315 can be adjusted. Accordingly, the orifice control insertion rod 3161 moves the point at which the removal liquid overflows from the outer circumferential surface of the long hole orifice 315 to the inner circumferential surface of the orifice control insertion rod 3161, and the orifice control insertion bar 3161 It is to allow the desorbing liquid to be discharged from the inner circumferential surface.

In addition, when the orifice control insertion bar 3161 is viewed from the side, the orifice control insertion bar 3161 is formed in a shape like a crescent moon as a whole.

The outer circumference of the insertion bar 3161a positioned at the outermost part of the orifice control insertion bar 3161 is formed to coincide with the circumference of the orifice 315a of the long hole orifice 315 . The inner circumferential line 3161b of the insertion bar has a smaller radius than the outer circumferential line 3161a of the insertion bar.

In addition, a mounting groove 313f equal to the thickness of the assembly plate 3162 is preferably formed on the outer peripheral side of the long hole orifice 315 in the side plate 313 . More specifically, the mounting groove 313f has the same thickness as the assembly plate 3162 in the space between the long hole orifice outer periphery 315a and an arc having a larger radius to the outside of the long hole orifice outer perimeter line 315a. formed to a depth of

The assembly plate 3162 is provided to fill the mounting groove 313f, and when assembled to the side plate 313, the assembly plate 3162 and the side plate 313 are integrated with each other. make it possible

If the mounting groove 313f is not formed in the side plate 313 as described above, as described above, the length of the long hole orifice 315, which is the distance through which the removal liquid passes and exits, becomes longer, thereby adversely affecting the discharge of the liquid. Since a negative effect is generated, a groove having the same depth as the thickness of the assembly plate 3162 is formed as a means to avoid this.

In addition, the assembly plate 3162 includes an assembly tab 3162a formed to be assembled to the side plate 313 from one side of the assembly plate 3162 . The assembly tab 3162a is preferably formed of, for example, at least two.

As a result, the orifice control insertion bar 3161 is inserted into the long hole orifice 315 to block a certain range of the outer periphery of the long hole orifice 315, so that the removal liquid from the long hole orifice 315 overflows. The starting lowest point can be adjusted to move toward the center of the side plate 313 .

In addition, the orifice adjustment insertion bar 3161 is provided in plurality so that the insertion bar outer circumferential line 3161a and the insertion bar inner circumferential line 3161b have a difference in radius from each other, and can be selectively replaced and assembled according to the setting of the lowest point can

In addition, the screw tecanter 300 further includes a connecting plate 318 installed on the outside of the side plate 313 so that the orifice adjusting member 316 can be fixed to the side plate 313 .

The connecting plate 318 includes an adjustment member assembly hole 318a formed to be assembled to the assembly plate 3162 and a side plate assembly hole 318b formed to be assembled to the side plate 313 . The side plate assembly hole (318b) is fastened with the nut (313c) in a state in which the side plate assembly bolt (313b) is inserted. The adjustment member assembly hole 318a is coupled to the assembly tab 3162a of the assembly plate 3162 with an adjustment member assembly bolt 318c.

As an example according to this embodiment, when the orifice adjusting member 316 is fastened by matching the outer circumferential line 3161a of the insertion bar and the outer circumferential line of the orifice 315a with each other, the outer circumferential line 3161a of the insertion bar and the insertion If the difference in the radius of the inner circumferential line 3161b is 5 mm, the lowest point of the long hole orifice 315 is increased by 5 mm. At this time, the lowest point means the outermost point of the long hole orifice 315, and the higher result means that the side plate 313 approaches the center direction.

In addition, if the radius of the insertion bar inner perimeter 3161b is changed to another orifice adjusting member 316 formed to be 5 mm smaller than the first, the lowest point of no skipping is 10 mm higher than the initial state. Of course, the radius of the inner circumferential line 3161b of the insertion bar may be applied as an appropriate value according to the actual situation.

Hereinafter, with reference to the accompanying drawings, a third embodiment of the impurities filtration and sand dewatering effect is enhanced according to the present invention will be described in detail.

This embodiment is another configuration in addition to the first embodiment, and is a configuration for changing the lowest point of no-going by blocking a certain range of the outer peripheral space of the long hole orifice 315 of the first embodiment with the orifice adjusting insert plate 317, and the rest Since the configuration is the same as that of the first embodiment, the description of the first embodiment is referred to.

In this embodiment, a predetermined space on the orifice outer circumferential line 315a side of the long hole orifice 315 is blocked with the orifice adjustment insert plate 317 so that the lowest point of the long hole orifice 315 is set at the center of the side plate 313 . By allowing it to move to the side, it is to have the effect of easily adapting to changes in the inflow amount and the dehydration rate.

In addition, in this embodiment, when the orifice adjustment insert plate 317 is used, only the height at which the eliminator overflows the long hole orifice 315 is changed, and the long hole orifice 315 is the distance through which the eliminator passes and exits. ) is the same without exceeding the thickness of the side plate 313 .

In this embodiment, the configuration of changing the water draining start point by putting an insert in a certain range of the long hole orifice outer circumferential line 315a of the long hole orifice 315 is similar to the second embodiment, but the fixing method of the insert is the first The second embodiment is disclosed in a different way.

13 to 15, when the configuration of the third embodiment will be described in detail, the screw tecanter 300 is provided so as to adjust the position at which the desorbent overflows from the long hole orifice 315 It further includes an orifice adjustment insert plate (317). The orifice adjustment insert plate 317 includes an insert plate tab 317a formed on one side of the orifice adjustment insert plate 317 .

The orifice control insert plate 317 is formed to have the same width as the thickness of the side plate 313 so that only the height at which the removal liquid overflows from the long hole orifice 315 can be adjusted, and the orifice adjustment insert plate 317 When viewed from the side, it is formed in the shape of a crescent moon as a whole.

In addition, the side plate 313 is inserted into the adjustment insert plate assembly hole 313d and the adjustment insert plate assembly hole 313d formed on the outer peripheral side of the side plate 313, and is coupled to the insert plate tab 317a It further includes an insert plate assembly bolt (313e) to be.

In this embodiment, the insert plate tab 317a is formed on the orifice adjustment insert plate 317, and the insert plate assembly bolt is formed in the adjustment insert plate assembly hole 313d formed on the outer peripheral side of the side plate 313. (313e) is put in the method to be fastened with the insert plate tab (317a).

At this time, the insert plate assembly bolt (313e) may be provided as, for example, a bolt with a hexagonal head hole, and the number is preferably provided with at least two.

In addition, after the assembly and fastening of the insertion plate assembly bolt (313e), the empty space of the bolt head portion of the insertion plate assembly bolt (313e) and the bolt end hole of the insertion plate assembly bolt (313e) is sealed, but after the insertion In preparation for disassembly of the plate assembly bolt 313e, it is preferable to finish the empty space with a space filling material such as, for example, metal powder bond.

As a result, the orifice adjustment insert plate 317 is inserted into the long hole orifice 315 to block a certain range of the outer periphery of the long hole orifice 315, so that the detachment liquid overflows from the long hole orifice 315. The starting lowest point can be adjusted to move toward the center of the side plate 313 .

In addition, the orifice adjustment insert plate 317 is provided in plurality so that the radius of the inner circumferential surface of the orifice adjustment insert plate 317 varies, and can be selectively replaced and assembled according to the setting of the lowest point.

In other words, the configuration of replacing and assembling a new one with a difference in the radial dimension of the inner circumferential surface of the orifice adjustment insert plate 317 is a concept similar to that of the second embodiment.

In addition, in the conventional screw decanter, in order to lower the position of the orifice 314 of the screw decanter once manufactured, the entire device is almost completely disassembled to separate the side plate 313 and the side plate 313 is reprocessed to balance the weight. It was a difficult task to recheck and reassemble.

However, in the present invention, the lowest point position of the long hole orifice 315 is manufactured to a position lower than the design value, and the orifice adjusting member 316 or the orifice adjusting insert plate 317 of an appropriate size is required according to the conditions during test operation or use. ) to raise the lowest point and adjust it, so the width of the orifice lowest point setting is widened. At this time, the position can be said to be very close to the inner peripheral surface of the cylindrical cylinder (311).

Organic dewatering contaminants and inorganic dehydrated sand are respectively discharged from the contaminant treatment machine. Dewatering contaminants are hydrophilic and have a large surface area of contaminants, and when the moisture is usually dehydrated to 70% level due to the intercellular water of organic matter, water is stored in the hopper or transported in a vehicle. doesn't come out

On the other hand, in the case of dehydrated sand, the surface area and hydrophilicity are smaller than that of contaminants, so the liquid component is easily separated from the sand. there is a problem.

As such, the moisture content ratio of the dewatered sand discharged from the contaminant treatment machine is an important factor. In order to discharge the sand by dewatering it to a level of half or less, the contaminant treatment screw of the present invention improved to control the shape of the orifice and the position of the lowest point A decanter 300 would be a suitable means.

In addition, the screw decanter 300 of the contaminant treatment machine according to the present invention has two functions, such as that the sand should be separated as much as possible with the minimum amount of moisture, and at the same time, the degree of purification of the desorbed liquid should be increased by minimizing the solids in the separation liquid. The effect of meeting the various conditions described above by changing the shape of the orifice and the lowest point of the orifice to satisfy all of the above can be verified.

With the above configuration, the screw decanter 300 of the foreign matter treatment machine with enhanced effect of filtration and sand dewatering according to the present invention is a foreign matter treatment process for treating various solids contained in manure, sewage, livestock manure, food waste, etc. It performs its function so that the sand component can be easily dehydrated and discharged.

As such, those skilled in the art to which the present invention pertains will understand that the above-described technical configuration of the present invention may be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention.

Therefore, the embodiments described above are to be understood as illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the following claims rather than the above detailed description, and the meaning and scope of the claims and their All changes or modifications derived from the concept of equivalents should be construed as being included in the scope of the present invention.
