Description

TECHNICAL FIELD The present invention relates to a contaminant collecting apparatus and a crushing apparatus for adulterating the same,

The present invention relates to a method and a device for pumping a filtrate discharged from a manure or livestock wastewater through a primary screen by a rotary screen and a pressurized dewatering process of a contaminant by a screw press with a cyclone, The filtrate is dispersed and supplied to remove fine contaminants such as seeds, beef hairs, and sebaceous glands, and the various residue components discharged from the seed removal screen are returned to the screw press for dehydration treatment together with the contaminants In one impregnated composite processing machine, two cutters, which are arranged in parallel in the up and down direction along the width direction, are axially rotatably installed in the inner space of the flow rate adjusting tank at the front entrance side of the rotary screen, and two cutter blades A lifting cutter for lifting the contaminant component with the aid of the lifting cutter, By applying the insert cutter of the type that passes between the cutter blades of the lifting cutter to each of the cutting machines, it is possible to cut and grind the contaminants, which have a relatively long length or a relatively large size, And the like.

In recent years, a large amount of manure and livestock wastewater have been generated due to the increase of the urban population and the increase in the size of the livestock farmers. The pollution of the ground water, the river and the coastal waters has become serious due to the manure and livestock wastewater, The odor generated from manure or livestock wastewater adversely affects the formation of a comfortable living environment.

In order to manage such manure and livestock wastewater from a governmental level, manure and livestock wastewater collected from each region are treated in separate purification facilities. However, in case of livestock wastewater, the concentration of suspended solids (SS) is 20,000 ~ 25,000 ppm level, there is a problem that overloading occurs during operation of the purification facility. Accordingly, in order to treat manure and livestock wastewater more efficiently, various kinds of impurities are removed from collected manure and livestock wastewater, And then sent to the final purification facility for treatment.

In order to separate manure and livestock wastewater into filtrate and impurities as described above, manure or livestock wastewater is introduced into the housing constituting the main body of the processor, and the filtrate generated in the primary impurity treatment process by the rotary screen and screw press is introduced into the filtrate And the filtrate stored in the filtrate reservoir is pumped to a cyclone connected to a seed removal screen and a centrifuge to remove fine contaminants such as seeds, animal hair, and sebaceous components contained in the filtrate. (Hereinafter, referred to as " patent registration ") has been known to the applicant as a prior application and patent registration (registration number: 10-0212298) in which a treated filtrate is supplied to a final purification facility through a filtrate discharge tank.

The apparatus for collecting and disposing the impurities and the filtrate from the influent of the manure and the livestock wastewater and the storing and discharging of the filtrate generated in the processing are collectively installed in one processor, , The overall volume and the installation area of the processor and the cost of the fabrication thereof are reduced to the maximum extent, and the fine contaminants such as seeds, animal hair, and fines contained in the filtrate can be more effectively removed.

However, even in the case of the prior art impregnated composite processing apparatus, when a large amount of impurities, which have a somewhat large volume, are input into a screw press through a rotary screen, it is somewhat difficult to crush the impurities with an appropriate size using only the extrusion screw of the screw press In addition, contaminants, such as ropes, strings or thin rods (such as twigs), whose lengths are somewhat long, are hardly cut by the extrusion screws of the screw presses and are rolled along the extrusion screws.

Therefore, in the dehydration process of the impurities by the screw press, the impurities of the impurities which have not been cut and crushed in an appropriate size cause unnecessarily large pores, so that the dehydration efficiency of the impurities is greatly lowered, and the extrusion screw of the screw press When a long length of the long-length contaminants is wound, the screw press may fail, malfunction, and overload, which may adversely affect the continuous and rapid processing of the contaminants by the impregnation processor.

The bottom surface of the screw casing 33 is in the form of a perforated plate capable of discharging the filtrate dewatered in the screw press 3 to the filtrate reservoir 4 in association with the filtrate outlet 32, The diameter of the dewatering hole 33a forming the sidewall is preferably about 6 to 8 mm and the dewatering outlet 36 is formed in the extrusion passage 31 in a state in which the dewatering hole 33a is formed into an extrusion passage 36a, So that the screw shaft end of the screw shaft passes through the impurity outlet 36 and protrudes into the discharge duct 37 by a predetermined length.

A discharge port 37a for discharging the dewatered contaminants is provided in the lower end of the discharge duct 37. The outlet port 37a of the screw shaft 33 extends through the rear surface of the screw casing 33, A driven sprocket 35 as a driving means for receiving the power of the screw motor 34 is provided at an end portion of the screw casing 33. A rotation support portion 38 for supporting the rotation operation of the extrusion screw 31 is provided on the rear side of the screw casing 33, (35a) and (38a) are placed on the drive bracket 39 of the housing 10a.

The rotary cutter 9 for performing the secondary cutting and crushing operation of the impurities in conjunction with the screw press 3 described above is provided on the outer side of the screw casing 33 (left side in FIG. 6) And is installed in the horizontal direction so as to rotate in the form of a worm gear in accordance with the rotation of the shaft of the extrusion screw 31 in a state of being engaged with the spiral wing portion of the extrusion screw 31 And the connecting portion between the screw casing 33 and the cutter casing 91 forms an opening for the operation of the rotary cutter 9.

When the connection portion between the screw casing 33 and the cutter casing 91 is formed as an opening as described above, the contaminant component conveyed along the inner space of the screw casing 33 by the rotation of the axis of the extrusion screw 31, It may be a part of the inside of the casing 91 but this is not a level that can interfere with the operation of connecting the extruding screw 31 and the rotary cutter 9 and the dehydration efficiency of the impurities, Since the cutter casing 91 itself is flatly installed with a dimension (3 to 4 cm) slightly larger than the thickness (1 to 2 cm) of the rotary cutter 9 as shown more clearly, The amount of the contaminants introduced into the space is also very small.

The inlet side of the cutter casing 91 except for the turning radius of the rotary cutter 9 may be formed in the form of a cover plate 91 so that the amount of the contaminants introduced into the cutter casing 91 can be further minimized, And the bottom surface of the cutter casing 91 is formed to be inclined downward so that the contaminant components introduced into the cutter casing 91 can flow back to the side of the screw casing 33 And the cutter casing 91 is connected to one side of the screw casing 33 so that the rotary cutter 9 can be replaced easily.

As a most preferred embodiment of the rotary cutter 9, three or four semicircular cutter units 92 are integrated in the form of a three-leaf clover or a four-leaf clover, as shown in FIGS. 9A to 9D, Likewise, each cutter unit 92 is rotated and inserted sequentially through the space between the spiral blades along the advancing direction of the spiral wing by the axial rotation of the extrusion screw 31, And the edge portion is formed as a sharp cutting edge portion 93 for cutting and crushing the contaminants.

A vertical cutter shaft 9a rotatably supported at the inside of the cutter casing 91 is integrally connected to the rotary cutter 9 at the center of the rotary cutter 9. The cutter shaft 9a, It is preferable that a bearing is interposed in a portion to be assembled with the cutter casing 91. At least two or more rotary cutters 9 are provided along the longitudinal direction of the extrusion screw 31, It is more preferable to ensure that the final cutting and crushing performance of the impurities by the rotary cutter 9 is sufficiently secured by arranging the rotary cutter 9 inside the cutter casing 91 at regular intervals, The cutter casings 91 may be individually (independently) applied.

Hereinafter, a process of dewatering treatment for separating various contaminants contained in manure and livestock wastewater from the filtrate using the impurity concentration processor 10 of the present invention will be described.

First, manure and livestock wastewater are collected by a collection vehicle such as a tank lorry, and manure and livestock wastewater are transported to an area where the purification facility is installed. Then, the discharge hose of the collection vehicle is connected to the inlet 1, the manures and the livestock wastewater are supplied to the flow control tank 21 through the inlet pipe 11, and the manure and the livestock wastewater stored in the tank lorry are supplied to the flow control tank 21 through the first inlet do.

The flow rate adjusting tank 21 is provided in the flow rate adjusting tank 21 so that the level of the manure and wastewater discharged into the housing 10a is lower than the height of the upper surface of the screen main body 22 of the rotary screen 2, So that the manure and the livestock wastewater to be introduced into the flow rate regulating tank 21 are prevented from being infested with seeds or sand or various other impurities .

Therefore, in the course of the manure and livestock wastewater fed into the flow rate adjusting tank 21 passing through the rotary screen 2, the water or the filtrate flows into the space between the metal plate and the metal ring constituting the screen body 22, The contaminants which flow into the first storage space 46 of the filtrate reservoir 4 through the lower filtrate outlet 24 and become larger in size among the contaminants contained in the manure and livestock wastewater, And is introduced into the hopper 25 of the screw press 3 through the separator 23.

As described above, in the course of passing through the rotary screen 2, a large amount of filtrate is firstly dehydrated, and the impurities in such a state are discharged to the extrusion screw (not shown) inside the screw press 3 31. The dewatered filtrate is introduced into the first storage space 46 of the filtrate reservoir 4 through the filtrate outlet 32 and the dregs of the filtrate are discharged through a screw press 3 through the discharge port 36 and the discharge port 37a of the discharge duct 37.

The filtrate flowing into the first storage space 46 of the filtrate storage tank 4 through the rotary screen 2 and the screw press 3 is in a state in which relatively large contaminants are filtered, A large amount of micro-contaminants are still contained. Therefore, among the filtrate flowing into the first storage space 46, micro-contaminants having a heavy specific gravity of the filtrate flows into the first storage space 46 having a funnel shape of the upper storm, So that it sinks intensively toward the narrow bottom side of the storage space 46.

Therefore, fine contaminants such as sand, which have settled to the bottom of the first storage space 46 by the main suction pipe 48 of the transfer pump 41 provided adjacent to the narrow bottom portion of the first storage space 46, And then the whole amount is transferred to the inside of the cyclone 5 through the transfer pump 41 and the transfer pipe 43 so that the sediment is accumulated in the bottom of the first storage space 46, So that the amount of the contaminants to be retained can be made almost zero.

Since the fine contaminants settled to the bottom of the filtrate reservoir 4 are completely discharged through the main suction pipe 48 of the transfer pump 41 in the first storage space 46 as described above, Only the filtrate not contained in the second storage space 47 flows into the second storage space 47 through an overflow passage (not shown) formed in the partition wall 45. The filtrate introduced into the second storage space 47 in this way is also supplied to the main suction pipe 48 (Not shown) connected to the second suction pipe (not shown).

Due to the internal structure of the filtrate reservoir 4, most of the fine contaminants mixed in the filtrate can be transferred to the inside of the cyclone 5 together with the filtrate by the transfer pump 41, It is possible to minimize or substantially reduce the amount of the contaminants that settle and stay in the bottom of the filtrate storage tank 4 and also to prevent the storage capacity of the filtrate storage tank 4 from being reduced by the precipitated contaminants, This makes it possible to extend the cleaning cycle of the filtrate reservoir 4 and the use period of the impregnation integrated processing machine 10 to the maximum extent and to incur an additional cost due to the cleaning operation of the filtrate reservoir 4, Contamination of the surrounding environment can also be minimized.

As described above, the liquid is discharged from the filtrate reservoir 4 separated into the first storage space 46 and the second storage space 47 through the main suction pipe 48 and the transfer pipe 43 of the auxiliary suction pipe and the transfer pump 41, And the microscopic contaminants supplied to the inside of the cyclone 5 together with the filtrate of the livestock wastewater are floated up to the upper part of the dirt having light specific gravity such as seed or animal hair according to the cyclone phenomenon due to the transfer pressure of the filtrate, A heavy load, such as a heavy load, sinks to the bottom.

Therefore, a light impurity such as seed or animal hair is injected into the seed removal screen 6 together with a small amount of filtrate through the seed discharge pipe 52 installed on the upper side of the cyclone 5, Through the filtrate discharge pipe 51 provided on the lower side of the cyclone 5, the remaining filtrate containing contaminants having heavy specific gravity such as sand is supplied to the centrifugal separator 7 side.

As described above, as the seed removal screen 6 is rotated by the screen motor 66, the filtrate is drained into the water drop through hole 61 on the surface of the impurity introduced into the seed removal screen 6, And the washing liquid 65 of the removing screen 6 is introduced into the filtrate discharging tank 8 through the filtrate discharging pipe 64. The seed and the residue separated from the filtrate are transferred to the seed discharging unit 63 by the transferring screw 62, And the feed hopper 25 into the screw press 3 so that the filtrate of seeds and debris is dehydrated again in the screw press 3.

The large amount of filtrate discharged into the centrifugal separator 7 is finally separated into the filtrate and the contaminant residue by the difference in specific gravity as the dehydrating screw 73 installed in the centrifugal separator 7 rotates at a high speed, The fine filtrate containing the sand is discharged to the fine discharge port 71a by the discharge screw 75 provided in the fine discharge pipe 71, The odor generated inside the housing 10a including the seed removing screen 6 is supplied to the deodorizing device 82 through the exhaust pipe 69 to be purified.

As described above, the third step of separation and dewatering processes are performed by the centrifugal separator 7 and the seed removing screen 6 connected to the rotary screen 2, the screw press 3 and the cyclone 5, The filtrate prepared in a clean state is stored in the filtrate discharge tank 8 and the filtrate stored in the filtrate discharge tank 8 is supplied to the final purification facility through the discharge pipe 81 to perform final treatment of manure or livestock wastewater .

Particularly, according to the impurity composite processing apparatus 10 of the present invention, the length of the contaminants flowing from the inlet 1 to the rotary screen 2 side together with the manure and livestock wastewater via the flow rate control tank 21 is somewhat longer or bulky The relatively large contaminants can be cut and crushed in advance in the inside of the flow rate adjusting tank 21 by the first cutting device 13 and the second cutting device 14, The unnecessary voids between the impurities injected into the screw press 3 can be reduced and the dehydration efficiency of the impurities in the screw press 3 can be greatly improved.

Further, by using the lifting cutter 14b of the second cutting machine 14 provided with the latching groove 14c, it is possible to easily raise the contaminants such as ropes, ropes or branches among the impurities contained in the manure or livestock wastewater A method in which the insert cutter 13b of the first cutter 13 is passed in a rotationally intersecting manner between two cutter blades installed at narrow intervals to form the respective lifting cutter 14b, Cutting machines 13 and 14, which are optimized for cutting the contaminants of a long and flexible material in such a manner that the insert cutter 13b is cut while press-fitting the insert cutter 13b between the two cutter blades, According to the preliminary arrangement, it is possible to prevent a malfunction, a malfunction, and an overload of the apparatus caused by winding of the contaminants into the extrusion screw 31 of the screw press 3 in advance.

On the other hand, when the insert cutter 13b is additionally disposed at a position corresponding to the position between the lifting cutters 14b in the longitudinal direction of the first cutter shaft 13a, A rope, a cord or a twig or the like is mainly cut by using an insert cutter 13b inserted between the cutters 13a and 13b and the other insert cutter 13b is cut by a different cutter such as a slightly thick cutter By crushing, the cutting and crushing function of the impurities can be dispersed more rationally, so that smooth and stable operation of the apparatus can be achieved.

In addition, among the contaminants whose length is somewhat longer or whose volume becomes relatively large, the remaining contaminants which have not been cut and crushed by using the cutters 13 and 14 in the flow rate regulating tank 21, It is possible to finally cut and crush the crushed material by the rotary cutter 9 to maximize the dewatering efficiency of the impurities by the screw press 3, It is possible to more reliably cut off the failure, malfunction, and overload phenomenon of the device due to winding by the extrusion screw 31 in the second cycle.

The rotary cutter 9 may have a structure in which three or four semicircular cutter units 92 are integrally formed in the form of three or four leaf clovers so that each cutter unit 92 has a spiral wing portion The cutting edge portion 93 of the rotary cutter 9 is formed in a spiral shape of the extruding screw 31 so that the cutting edge portion 93 of the rotary cutter 9 does not have to be in the form of a spiral The cutting and crushing performance of the contaminants can be maximized by the method of engaging the wings with the gears and the cutting devices 13 and 14 in the flow rate adjusting tank 21 and the rotary cutter 9) can be used at the same time to provide a contaminant synthesis processor 10 optimized for continuous and rapid high-efficiency dehydration processing of the contaminants.
