DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] As described in the background technology, the prior art needs to stop filtering the wastewater when cleaning the debris, and when the above-mentioned device pushes the impurities on the filter, it is easy to push the impurities remaining on the filter to between the push plate and the cylinder. For this reason, this embodiment provides a slaughterhouse wastewater treatment system, which achieves the purpose of cleaning the filter without stopping the machine and can avoid impurities remaining on the filter.

[0022] See also Figure 1-11 This embodiment proposes a slaughterhouse slaughter wastewater treatment system including a treatment box 1 with an opening on the top. The front of the treatment box 1 is fixedly connected to a drain pipe 4, which is connected to an external pumping system for discharging treated sewage. A box cover 2 is fixedly installed on the top of the treatment box 1. The inside of the box cover 2 is fixedly connected to a water inlet pipe 3, which is connected to an external sewage discharge system. Sewage enters the treatment box 1 through the water inlet pipe 3.

[0023] A partition 5 is fixedly connected to the inside of the treatment box 1, and an intermediate plate 6 is fixedly connected between the partition 5 and the treatment box 1. Filters 9 are fixedly installed on both sides of the intermediate plate 6 to filter impurities in the sewage. The upper surface of the intermediate plate 6 is fixedly connected to a water diversion plate 7, and the other side of the water diversion plate 7 is in contact with the top wall of the treatment box 1, which can guide the sewage to flow to the filter 9 on one side.

[0024] Two cleaning mechanisms are slidably connected between the partition 5 and the processing box 1, corresponding to the two filter screens 9 respectively, for cleaning impurities on the filter screens 9. The processing box 1 is provided with a driving mechanism for driving the water distribution plate 7 to move horizontally, and the driving mechanism and the cleaning mechanism are connected through a linkage mechanism to achieve synchronous action.

[0025] Specifically, the cleaning mechanism includes a movable plate 14 and a mounting plate 16, both of which are slidably connected between the partition 5 and the processing box 1. A circular hole is opened inside the movable plate 14, and a first spring 18 is fixedly connected to the circular hole. The other end of the first spring 18 is fixedly connected to the connecting column 15. The other end of the connecting column 15 slides through the circular hole and is fixedly connected to the mounting plate 16. A cleaning brush 17 is installed on the side of the mounting plate 16 away from the movable plate 14. The cleaning brush 17 is in contact with the filter screen 9. The elastic force of the first spring 18 can make the cleaning brush 17 always stick to the filter screen 9 during the process of moving away from the middle plate 6.

[0026] The driving mechanism includes a motor 28 installed on the back of the processing box 1, and a driving shaft 29 is rotatably installed between the partition 5 and the processing box 1. One end of the driving shaft 29 is fixedly connected to the output end of the motor 28, and the outer surface of the driving shaft 29 is fixedly connected to the gear 30. When the motor 28 is working, it drives the driving shaft 29 and the gear 30 to rotate.

[0027] The outer surface of the water diversion plate 7 is fixedly connected to the third slider 32, and the third slider 32 is slidably connected to the inside of the partition 5 to ensure that the water diversion plate 7 moves smoothly. The side of the third slider 32 away from the water diversion plate 7 is fixedly connected to the rack 31 adapted to the gear 30. The rotation of the gear 30 can drive the rack 31 and the water diversion plate 7 to move.

[0028] Two symmetrical rectangular grooves are provided inside the rack 31, in which a third spring 35 is fixedly connected. The other end of the third spring 35 is fixedly connected to the fourth slider 34. The other end of the fourth slider 34 slides through the rectangular groove and is fixedly connected to the teeth 33 adapted to the gear 30. When the gear 30 drives the rack 31 to move to one side to the maximum extent, the gear 30 continues to rotate, which will drive the teeth 33 to move in the direction of the rack 31 and compress the third spring 35. When the gear 30 rotates to no longer contact the teeth 33, the third spring 35 will drive the teeth 33 to reset. As a result, during the continuous rotation of the gear 30, the teeth 33 will perform horizontal reciprocating movement. When the gear 30 reverses, it can drive the teeth 33 and the rack 31 to move horizontally in the opposite direction, thereby achieving synchronous operation with the cleaning mechanism.

[0029] The linkage mechanism includes a first support plate 10 fixedly connected to the outer surface of the partition 5, a reciprocating screw 11 is rotatably installed between the first support plate 10 and the processing box 1, a driven shaft 40 is rotatably installed inside the processing box 1, and the driven shaft 40 and the reciprocating screw 11 are connected through a bevel gear set. A one-way bearing 36 is installed on the outer surface of the driving shaft 29, and a synchronous wheel 37 is fixedly installed on the outer surface of the one-way bearing 36 and the driven shaft 40. The two synchronous wheels 37 are connected by a synchronous belt transmission. When the driving shaft 29 rotates forward, it can drive one of the one-way bearings 36 and the synchronous wheel 37 to rotate forward, and the other one-way bearing 36 rotates idly, thereby transmitting power to one of the reciprocating screws 11. When the driving shaft 29 reverses, it can drive the other one-way bearing 36 and the synchronous wheel 37 to reverse, and one of the one-way bearings 36 rotates idly, thereby transmitting power to the other reciprocating screw 11.

[0030] The outer surface of the reciprocating screw 11 is threadedly connected to the threaded plate 12, and the outer surface of the threaded plate 12 is fixedly connected to the first slider 13. The first slider 13 is slidably connected to the inside of the partition 5, and the side of the first slider 13 away from the threaded plate 12 is fixedly connected to the movable plate 14. When the reciprocating screw 11 rotates, the threaded plate 12 drives the movable plate 14 to reciprocate through the first slider 13.

[0031] The outer surface of the mounting plate 16 is fixedly connected to a second slider 27, which is slidably connected to the inside of the partition 5. The bottom surface of the second slider 27 is fixedly connected to the second wedge block 26, and the side away from the mounting plate 16 is fixedly connected to the first wedge block 25, which is used to cooperate with other components to realize the up and down movement of the cleaning brush 17.

[0032] The inside of the processing box 1 is fixedly connected to the box body 19, and the inside of the box body 19 is fixedly connected to the second spring 21. The other end of the second spring 21 is fixedly connected to the connecting plate 20. The other side of the connecting plate 20 slides through the box body 19 and is fixedly connected to the first wedge plate 22 adapted to the second wedge block 26. The first wedge plate 22 is fixedly connected to the second support plate 23 on one side close to the box body 19. The upper surface of the second support plate 23 is fixedly connected to the second wedge plate 24 adapted to the first wedge block 25. In the initial state, the inclined surface of the first wedge block 25 contacts the inclined surface of the second wedge plate 24. When the single cleaning of the filter screen 9 is completed and the movable plate 14 is reset, the inclined surface of the second wedge block 26 contacts the inclined surface of the first wedge plate 22.

[0033] The two filter screens 9 are provided with a collecting mechanism on the sides away from each other. The collecting mechanism includes a collecting box 42 with an opening on the top. The collecting box 42 is fixed inside the processing box 1 through a long strip. The positioning plate is fixedly connected inside the processing box 1. The side of the collecting box 42 away from the long strip is in contact with the filter screen 9 and the positioning plate. The side of the collecting box 42 close to the filter screen 9 is provided with a feed port. A baffle 43 is slidably connected inside the feed port to control the switch of the feed port.

[0034] The side of the baffle 43 away from the filter 9 is fixedly connected to the slide rod 44, and the other end of the slide rod 44 slides through the third slider 32 and is fixedly connected to the cylinder 39. The inside of the cylinder 39 is fixedly connected to the fourth spring 45, and the other end of the fourth spring 45 is fixedly connected to the collection box 42. The fourth spring 45 can drive the baffle 43 to reset and close the feed port.

[0035] The side of the mounting plate 16 close to the collection box 42 is fixedly connected to the push plate 41. When the mounting plate 16 moves toward the collection box 42, the push plate 41 can push the baffle 43 to open the feed port, making it easier for debris to enter the collection box 42.

[0036] Both sides of the water diversion plate 7 are fixedly connected to the downward-inclined guide plates 8, which can guide the sewage to flow more smoothly to the filter screen 9. Both side walls of the treatment box 1 are fixedly connected to the blocking blocks 38, which are used to block the top opening of the collection box 42 to prevent sewage from entering the collection box 42.

[0037] How it works Sewage inlet and diversion: Sewage enters treatment tank 1 through inlet pipe 3. Motor 28 drives drive shaft 29, which in turn rotates gear 30. Gear 30 engages teeth 33 on rack 31, causing rack 31 to move diverter plate 7 horizontally via third slider 32. Guide plates 8 on either side of diverter plate 7 guide sewage toward filter screen 9 on one side. When diverter plate 7 moves to the left, sewage flows through right guide plate 8 toward filter screen 9 on the right side. When it moves to the right, sewage flows toward filter screen 9 on the left side, achieving alternating filtration between the two filter screens 9. The filtered sewage is then discharged through drain pipe 4.

[0038] Cleaning stage: When the driving shaft 29 rotates, the driven shaft 40 is driven to rotate through the one-way bearing 36 and the synchronous wheel 37. The driven shaft 40 drives the reciprocating screw 11 to rotate through the bevel gear set. Under the action of the reciprocating screw 11, the threaded plate 12 drives the movable plate 14 to move toward the collection box 42 through the first slider 13. The mounting plate 16 moves synchronously with the movable plate 14. At this time, the inclined surface of the first wedge block 25 on the mounting plate 16 squeezes the inclined surface of the second wedge plate 24, forcing the second wedge plate 24 to move backward. The second wedge plate 24 The first wedge plate 22 and the connecting plate 20 are driven to move backward synchronously by the second support plate 23, and the second spring 21 in the box body 19 is compressed. When the first wedge plate 22 moves backward to the maximum extent, the movable plate 14 continues to drive the mounting plate 16 to move, so that the second wedge block 26 moves in front of the first wedge plate 22, forming a block for the first wedge plate 22, preventing it from returning to its original position under the action of the second spring 21. At this time, the elastic force of the first spring 18 makes the cleaning brush 17 fit closely to the surface of the filter screen 9 to clean the filter screen 9.

[0039] Impurity collection: During the movement of the mounting plate 16, the push plate 41 pushes the baffle 43 to overcome the elastic force of the fourth spring 45 and move outward, opening the feed port of the collection box 42. The impurities cleaned by the cleaning brush 17 enter the collection box 42 through the feed port. When the push plate 41 is separated from the baffle 43, the fourth spring 45 drives the baffle 43 to reset, closing the feed port to prevent sewage from entering the collection box 42. The blocking block 38 simultaneously blocks the top opening of the collection box 42 to further isolate the sewage.

[0040] When the moving plate 14 returns to its initial position, the second wedge block 26 is separated from the first wedge plate 22. Under the joint action of the first spring 18 and the second spring 21, the mounting plate 16, the cleaning brush 17, the second wedge block 26 and the first wedge block 25 are reset and contact with the filter screen 9 again, ready for the next cleaning.

[0041] Circular operation: Under the continuous drive of the motor 28, the water distribution plate 7 moves left and right periodically, alternately switching the filter screen 9. At the same time, the linkage mechanism drives the corresponding cleaning mechanism to alternately clean the filter screen 9 in the non-filtering state, realizing a continuous cycle of filtration and cleaning, ensuring that the sewage treatment process is uninterrupted and efficient.
