In general, a screw decanter is a device that continuously separates, dehydrates, and discharges solids having a low sedimentation rate in water due to similar specific gravity to water.

The principle of the screw decanter is to maximize the centrifugal effect by using high-speed rotation to increase the sedimentation speed of the solid material so that the solid material is rapidly driven away from the center, and the solid material and the desorbed liquid separated from the solid material by using the rotation difference of the screw each to be discharged separately.

Hereinafter, a first embodiment of the screw decanter for treating contaminants according to the present invention will be described in detail with reference to the accompanying drawings.

As shown, the screw decanter for contaminants treatment according to the present invention is a main component as an outer bowl 100, an inner screw 200, an inlet pipe 300, a desorbent outlet 400, a solid outlet 500, a bed 600 ), a cover 700 and an electric motor 800 .

First, the present invention is formed in a form in which a horizontally placed cylindrical cylinder 110 and a conical cylinder 120 whose diameter gradually decreases from one side of the cylindrical cylinder 110 to the outside are extended, and the inflow liquid is accommodated therein. It is installed as the inner shaft of the bowl 100 and the outer bowl 100, and includes an inner screw 200 having a predetermined gap with the inner peripheral surface of the outer bowl 100.

In addition, the present invention includes an inner copper pulley 230 and an outer copper pulley 160 respectively mounted on the outer copper bowl 100 and the inner copper screw 200 and positioned adjacent to each other, the inner copper pulley 230 and the outer copper pulley Reference numeral 160 is connected to one electric motor 800 . A driving timing pulley 810 is mounted on one side of the electric motor 800 , and the driving timing pulley 810 is connected to the inner pulley 230 and the outer pulley 160 by a timing belt 820 , respectively. Therefore, by connecting the timing belt 820 to the inner copper pulley 230 and the outer copper pulley 160, the outer copper bowl 100 and the inner copper screw 200 generate a rotation difference with each other.

Therefore, the outer bowl 100 and the inner screw 200 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 and separated and discharged by centrifugal force due to rotation. function.

In addition, in the present invention, the inner copper screw 200 corresponding to the cylindrical cylinder 110 side ejects the ejection chamber 220 and the inflow of the ejection chamber 220 into the interior of the cylindrical cylinder 110 . A pipe 221 is included, and the jet pipe 221 has a plurality of jet holes 222 formed on a main surface of the jet pipe 221 .

In addition, the inlet hollow shaft 210 is installed at the center of the ejection chamber 220, and the inlet hollow shaft 210 extends and protrudes to the outside. At this time, the inlet pipe 300 provided with the inlet 310 is fixed to the inlet pipe holder 320 while maintaining a predetermined gap inside the inlet hollow shaft 210 .

In addition, the present invention provides a plurality of interaxial bearings 170 positioned in the space between the shafts of the outer bowl 100 and the inner screw 200 and a plurality of fixed bearings for fixing the inner screw 200 to the bed 600 ( 240), and the cover 700 surrounding the entire rotating body including the external bowl 100 and the internal screw 200 is fixed to the bed 600.

In addition, the cylindrical cylinder 110 includes a side plate 130 installed on the side surface of the cylindrical cylinder 110, and the side plate 130 is the outer bowl 100 so that the desorbed liquid can be discharged. It includes a long hole orifice 132 formed at the same distance from the center of the side plate (130). Of course, the side plate 130 is formed in the same circular plate as the cylindrical cylinder (110).

In other words, the solids dehydrated in the external bowl 100 are discharged to the end of the conical cylinder 120 , and the desorbed liquid is discharged to the long hole orifice 132 .

On the other hand, when explaining the operation of the screw decanter for contaminant treatment according to the present invention, the solid-liquid mixture is introduced into the inlet pipe 300 inside the inlet hollow shaft 210 through the inlet 310. . The solid-liquid mixture introduced into the inlet pipe 300 enters the ejection chamber 220 , and then is ejected into the cylindrical cylinder 110 through the ejection hole 222 . The ejected solid-liquid mixture comes close to the inner peripheral surface of the outer bowl 100 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 100 . If the inflow action of the solid-liquid mixture continues, the water level rises, and the water level moves closer to the axial center of the side plate 130 from the outermost side of the long hole orifice 132 formed in the side plate 130 . When this occurs, the leaching liquid overflows into the long hole orifice 132 and is discharged to the outside through the eliminative liquid outlet 400 .

In addition, the solid material in close contact with the inner circumferential surface of the outer bowl 100 is pushed out toward the conical cylinder 120 side by the transfer action of the inner copper screw 200 and exits the water surface to the beach.

In the process in which the solid is moved by the inner moving screw 200 along 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 110 in which the centrifugal force is greater through the gap between the inner screw 200 and the conical cylinder 120 . The solids pass through the beach and the dehydration action continues, and collects at the solids outlet 500 through the solids outlet blades 121 at the end of the conical cylinder 120 and discharges to the outside.

In addition, the long hole orifice 132 is a water drain hole, and serves as a weir through which the talismant overflows, and is formed in a long hole type compared to the conventional background art orifice 131 having a circular shape. .

When the orifice 131, which is a conventional background art, is formed in a circular shape, the width of the non-overflowing weir is narrow, and when the amount of inflow of the leaching liquid 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 120 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 that the inflow is limited.

In contrast, the long hole orifice 132 of the present invention is formed in a long hole shape so that even if the inflow increases rapidly, the area of the long hole orifice 132 is wide and the water draining speed is fast, so that a sudden rise of the water level can be prevented, Since the change in 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 in the amount of the desorbent is improved.

In addition, the present invention is limited to contaminants, and the material to be treated by the screw decanter is sewage in which, in addition to sand, a larger amount of fine organic suspended solids are evenly distributed and coagulated throughout, viscosity, surface tension, cohesion and adhesion. Since it is larger than this fresh water, the effect of draining water in a narrow space such as the circular orifice 131 of the background art is not good. On the other hand, the long hole orifice 132 of the present invention is formed in a long hole shape, and the water draining effect is superior to that of the circular orifice 131 by increasing the non-overflowing width. As such, the orifice needs to have a large width of a single no-flip, not the sum of the total area, so that the water draining effect is improved.

Accordingly, due to the long hole orifice 132 of the present invention, the water draining width of a single no-pass is widened, so that the water draining speed is increased and the change of the beach is reduced to increase the sand dewatering effect.

In addition, in the screw decanter for contaminant treatment according to the present invention, the specific gravity of the dewatering material is sand (true specific gravity 2.65), which is relatively larger than that of the liquid, so the separation rate is very fast due to the specific gravity difference inside the outer bowl 100. . Accordingly, there is an advantageous condition that sand is not easily discharged even in the long hole orifice 132, which has a high non-overturning speed, because the sand is strongly adhered from the center to the outside almost simultaneously with the introduction of the mixture.

In addition, the long hole orifice 132 has an effect that can shorten the length of the cylindrical cylinder 110 of the outer bowl 100, or can be eliminated.

More specifically, the internal volume of the cylindrical cylinder 110 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 110 in relation to the residence time and throughput.

In addition, referring to FIG. 3 , the long hole orifice 132 has a shape similar to that of combining two adjacent circular orifices 131 into one, and the two points on the circumference farthest from the axial center of the side plate 130 are arced. The main line tangentially connected to the orifice outer perimeter line 132a is called the orifice inner perimeter line 132b, and the main line tangentially connecting two points on the circumference closest to the axial center of the side plate 130 with an arc is called the orifice inner perimeter line 132b.

The long hole orifice 132 is formed in a shape consisting of the orifice outer circumferential line 132a and the orifice inner circumferential line 132b, and the orifice outer circumferential line 132a and the orifice inner circumferential line 132b are the side plates ( 130) becomes a part of the circumference of the concentric circle.

In addition, the long hole orifice 132 is located on the same circumference from the axial center of the side plate 130, is formed in plurality at regular intervals. The long hole orifice 132 is preferably formed of, for example, three or four. Of course, the long hole orifice 132 may be formed in various numbers depending on the size of the side plate 130 .

In summary, the present invention is due to the long hole orifice 132 formed in the side plate 130 of the outer bowl 100, the sedimentation treatment performance is further improved by increasing the draining rate at which the desorbed liquid separated from the solids overflows. can be promoted

Hereinafter, a second embodiment of the screw decanter for treating contaminants according to the present invention will be described in detail with reference to the accompanying drawings.

This embodiment is a configuration in addition to the first embodiment, and is a configuration for changing the lowest point without skipping by blocking a certain range of the outer circumferential space of the long hole orifice 132 of the first embodiment with the orifice adjusting member 140, and the rest of the configuration is Since it is the same as the first embodiment, the description of the first embodiment is used.

First, looking at the phenomenon according to the position of the lowest point of the orifice 131, which is a conventional background art, if the lowest point of the orifice 131 is too low, the thickness of the annular solution becomes thin, so the possibility that solid material is generally included in the leaching solution increases will do In this case, when the lowest point is low, it means that the orifice 131 is biased outward from the center.

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 131 is high, a phenomenon opposite to the above occurs. In this case, when the lowest point is high, it means that the orifice 131 is biased toward the inside.

In order to cope with such a problem, in the present invention, a method for changing the lowest point of the orifice 131 while the screw decanter for contaminant treatment is in use is proposed.

More specifically, by blocking the orifice outer circumferential line (132a) side of the long hole orifice 132 with the orifice adjusting member 140, the lowest point of the long hole orifice 132 can be moved to the center side of the side plate 130 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 131 is generally used in a way that the blocking plate is in surface contact with the side plate, and the method of blocking the blocking plate from being in surface contact on a plane is a simple method, but the orifice ( 131), the overflowing tally liquid is clogged with the diaphragm, so there is a problem in that the height of the weir is doubled in stages.

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, and 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 131, and the secondary weir may refer to the blocking plate. Accordingly, there is a problem of abrasion of the diaphragm and the orifice 131, and a problem of impairing the stability of solid-liquid separation due to a pocket phenomenon vortex.

In contrast to this, in the present embodiment, when the orifice adjusting member 140 is used, only the height at which the removal solution overflows from the long hole orifice 132 is changed, and the long hole orifice 132, which is the distance through which the removal solution passes and exits. The length of the side plate 130 is the same without exceeding the thickness. In addition, there is no change in the width of the long hole orifice 132, 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 another side effect.

4 to 6, when the configuration of the present embodiment will be described in detail, the screw decanter for contaminants treatment is an orifice adjusting member provided to adjust the position at which the desorbing liquid overflows from the long hole orifice 132 (140).

The orifice adjustment member 140 is one side of the orifice adjustment insertion rod 141 to be assembled to the orifice adjustment insertion rod 141 and the connection plate 150 to be described later to be inserted into the outer circumferential surface of the long hole orifice 132 Includes an assembly plate 142 connected in the vertical direction.

That is, when the orifice adjusting member 140 is viewed from the side, the cross section of the orifice adjusting member 140 is formed in an overall shape such as a 'L'.

In addition, the orifice control insertion bar 141 is formed to have the same width as the thickness of the side plate 130 so that only the height at which the removal solution overflows from the long hole orifice 132 can be adjusted. Accordingly, the orifice control insertion rod 141 moves the point at which the removal liquid overflows from the outer circumferential surface of the long hole orifice 132 to the inner circumferential surface of the orifice control insertion bar 141, and the orifice control insertion bar 141 of It is to allow the desorbing liquid to be discharged from the inner circumferential surface.

In addition, when the orifice control insertion bar 141 is viewed from the side, the orifice control insertion bar 141 is formed in the shape of a crescent as a whole.

The outer circumference of the insertion bar 141a located at the outermost part of the orifice control insertion bar 141 is formed to coincide with the circumference of the orifice 132a of the long hole orifice 132 . The inner circumferential line 141b of the insertion bar has a smaller radius than that of the outer circumferential line 141a of the insertion bar.

In addition, the side plate 130 preferably has a mounting groove 130a equal to the thickness of the assembly plate 142 is formed on the outer peripheral side of the long hole orifice 132 . More specifically, the mounting groove 130a has the same thickness as the assembly plate 142 in the space between the long hole orifice outer periphery 132a and an arc with a larger radius to the outside of the long hole orifice outer perimeter line 132a. formed to a depth of

The assembly plate 142 is provided to fill the mounting groove 130a, and when assembled to the side plate 130, the assembly plate 142 and the side plate 130 are integrated with each other. make it possible

If the mounting groove 130a is not formed in the side plate 130 as described above, as described above, the length of the long hole orifice 132 is lengthened, which has a negative effect that adversely affects the discharge of the liquid. As a means to avoid this, a groove having the same depth as the thickness of the assembly plate 142 is formed.

In addition, the assembly plate 142 includes an assembly tab 142a formed to be assembled to the side plate 130 from one side of the assembly plate 142 . The assembly tab 142a is preferably formed of, for example, at least two.

As a result, the orifice adjustment insertion bar 141 is inserted into the long hole orifice 132 to block a certain range of the outer periphery of the long hole orifice, the lowest point at which the removal solution starts to overflow from the long hole orifice 132 can be adjusted to move toward the center of the side plate.

In addition, the orifice control insertion bar 141 is provided in plurality so that the insertion bar outer circumferential line 141a and the insertion bar inner circumferential line 141b have a difference in radius from each other, to be selectively replaced and assembled according to the setting of the lowest point can

In addition, the screw decanter for treating contaminants further includes a connection plate 150 installed on the outside of the side plate 130 so that the orifice adjusting member 140 can be fixed to the side plate 130 .

The connecting plate 150 includes an adjustment member assembling hole 150a formed to be assembled to the assembling plate 142 and a side plate assembling hole 150b formed to be assembled to the side plate 130 . In the side plate assembly hole 150b, the side plate assembly bolts 133a are inserted and fastened with the nut 133b. The adjustment member assembly hole 150a is fastened with the assembly tab 142a of the assembly plate 142 with an adjustment member assembly bolt 151 .

As an example according to this embodiment, when the orifice adjusting member 140 is fastened by matching the insertion bar outer circumferential line 141a and the orifice outer circumferential line 132a with each other, the insertion bar outer circumferential line 141a and the insertion If the difference in the radius of the inner circumferential line 141b is 5 mm, the lowest point of the long hole orifice 132 is increased by 5 mm. In this case, the lowest point means the outermost point of the long hole orifice 132 , and the higher result means closer to the center direction of the side plate 130 .

In addition, if the radius of the inner circumference of the insertion bar 141b is changed to another orifice adjusting member 140 formed to be smaller than 5 mm, the lowest point of no skipping is a result that is higher than the initial state by 10 mm. Of course, the radius of the outer circumferential line 141a of the insertion bar and the inner circumferential line 141b of the insertion bar may be applied as appropriate values according to the actual situation.

Hereinafter, a third embodiment of the screw decanter for treating contaminants according to the present invention will be described in detail with reference to the accompanying drawings.

This embodiment is another configuration in addition to the first embodiment, and it is a configuration to change the lowest point without skipping by blocking a certain range of the outer periphery space of the long hole orifice 132 of the first embodiment with the orifice adjustment insert plate 143, Since the rest of the configuration is the same as that of the first embodiment, the description of the first embodiment is referred to.

In this embodiment, the orifice outer circumferential line (132a) side of the long hole orifice 132 is blocked with the orifice adjustment insert plate 143 to move the lowest point of the long hole orifice 132 to the center side of the side plate 130 By making it possible, it is to have the effect of easily adapting to changes in the inflow amount and the dehydration rate.

In addition, in the present embodiment, when the orifice adjustment insert plate 143 is used, only the height at which the removal solution overflows from the long hole orifice 132 is adjusted, and the long hole orifice 132 which is the distance through which the removal solution passes through ) is the same without exceeding the thickness of the side plate 130 .

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 periphery 132a of the long hole orifice 132 is the same as that of the second embodiment, but the fixing method of the insert is the second It is disclosed in a different way than the embodiment.

7 to 10, when the configuration of the present embodiment will be described in detail, the screw decanter for contaminants treatment is an orifice adjusting insert provided to adjust the position at which the desorbing liquid overflows from the long hole orifice 132 It further includes a plate 143 . The orifice adjustment insert plate 143 includes an insert plate tab 143a formed on one side of the orifice adjustment insert plate 143 .

The orifice adjustment insert plate 143 is formed to have the same width as the thickness of the side plate 130 so that only the height at which the removal solution overflows from the long hole orifice 132 can be adjusted. Accordingly, the orifice adjustment insert plate 143 moves the point at which the removal liquid overflows from the outer peripheral surface of the long hole orifice 132 to the inner peripheral surface of the orifice adjustment insert plate 143, and the inner peripheral surface of the orifice adjustment insert plate 143 It is to allow the leaching liquid to be discharged from the

In addition, when the orifice adjustment insert plate 143 is viewed from the side, the orifice adjustment insert plate 143 is formed in a shape like a crescent moon as a whole.

In addition, the side plate 130 is inserted into the adjustment insert plate assembly hole 134 and the adjustment insert plate assembly hole 134 formed on the outer peripheral side of the side plate 130, and is coupled to the insert plate tab 143a. It further includes an insert plate assembly bolt (134a) to be.

In this embodiment, the insert plate tab 143a is formed on the orifice adjustment insert plate 143, and the insert plate assembly bolt is formed in the adjustment insert plate assembly hole 134 formed on the outer peripheral side of the side plate 130. (134a) is put in the method to be fastened with the insert plate tab (143a).

At this time, the insert plate assembly bolt (134a) may be provided as, for example, a bolt with a hexagonal head, and the number is preferably provided with at least two.

In addition, after the assembly and fastening of the insert plate assembly bolt 134a, the empty space of the bolt head portion of the insert plate assembly bolt 134a and the bolt end hole of the insert plate assembly bolt 134a is sealed, but after In preparation for disassembly of the insert plate assembly bolt 134a, it is preferable to finish the empty space with a space filling material such as metal powder bond.

As a result, the orifice adjustment insert plate 143 is inserted into the long hole orifice 132 to block a certain range of the outer periphery of the long hole orifice 132, so that the detachment liquid overflows from the long hole orifice 132. It is possible to adjust the starting lowest point to be moved to the center side of the side plate 130 .

In addition, the orifice adjustment insert plate 143 is provided in plurality so that the radius of the inner circumferential surface of the orifice adjustment insert plate 143 varies, and can be selectively replaced and assembled according to the setting of the lowest point.

In other words, the method of replacing and assembling a new one with a difference in the radial dimension of the inner circumferential surface of the orifice adjusting insert plate 143 is the same as that of the second embodiment.

In addition, in the conventional screw decanter, in order to lower the orifice position of the screw decanter once manufactured, the entire device was almost completely disassembled to separate the side plate, and the side plate was reprocessed to reconfirm and reassemble the weight balancing state. .

However, in the present invention, the lowest point position of the long hole orifice 132 is manufactured to a position lower than the design value, and the orifice adjusting member 140 or the orifice adjusting insert plate 143 of an appropriate size as needed 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 a height very close to the inner peripheral surface of the cylindrical cylinder (110).

In addition, although the screw decanter for waste treatment according to the present invention has a sand dewatering function and is used alone, it is mainly used as a device for dewatering sand by being included in a foreign matter treatment machine.

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, and when moisture is dehydrated by organic substances such as intercellular water, water does not escape during storage in a hopper or transportation of vehicles.

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 screw for contaminant treatment of the present invention is improved so that the shape of the orifice and the position of the lowest point can be adjusted. A decanter would be a suitable means.

In addition, the screw decanter for contaminant treatment according to the present invention needs to separate as much sand as possible with the minimum amount of moisture and at the same time minimize the amount of solids in the separation liquid to increase the degree of purification of solids. The effect of meeting the various conditions described above by changing the lowest point of the orifice may be verified.

With the configuration as described above, the screw decanter for contaminant treatment according to the present invention is a contaminant treatment process for treating various solids contained in manure, sewage, livestock manure, food waste, etc. so that the sand component can be easily dehydrated and discharged perform the function

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.
