DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figure 1 , a waste solid-liquid separation and treatment device with a filter press structure, comprising: a separation box 5, a pressure plate 9, a driving structure, a bottom plate 4 and a base 1, wherein: like Figure 1-Figure 3As shown, the separation box 5 is vertically arranged, the base 1 is horizontally arranged below the separation box 5, a column 2 is vertically fixed on the base 1, the top of the column 2 is fixed on the outer wall of the separation box 5, and a scissor lift 3 is provided on the upper surface of the base 1 for driving the bottom plate 4 to move vertically, so that the bottom plate 4 abuts against the bottom surface of the separation box 5 and seals the bottom surface of the separation box 5; The base 1 is horizontally arranged to support the entire device, and the column 2 connects the base 1 and the separation box 5 to provide support for the entire device; a scissor lift 3 is provided on the base 1 to drive the bottom plate 4 to move vertically to seal the bottom surface of the separation box 5; like Figure 3-7 and Figure 12-Figure 17 As shown, connecting plates 11 are horizontally fixed on the upper and lower sides of the interior of the separation box 5, and multiple partitions 13 are vertically fixed between the two connecting plates 11. The partitions 13 are evenly spaced, and the opposite side of two adjacent partitions 13 is an arc surface. A filter screen 12 is rotatably fitted between the two adjacent partitions 13. The two sides of the filter screen 12 are arc surfaces and fit tightly with the arc surfaces of the partitions 13. A driving structure is provided on the connecting plate 11 to drive the filter screen 12 to flip, and the filter screen 12 and the partition 13 that cooperate with each other form a holding chamber for accommodating waste. A feeding pipe 10 is fixed to the top of the connecting plate 11 to accommodate waste into the holding chamber.

[0034] Two connecting plates 11 are horizontally fixed to the upper and lower sides of the separation box 5 for installing partitions 13. The partitions 13 are evenly spaced, and the opposite sides of two adjacent partitions 13 are arc surfaces; the filter screen 12 is rotatably fitted between adjacent partitions 13, and the two sides of the filter screen 12 are arc surfaces and fit tightly with the arc surfaces on the partitions 13, so that the filter screen 12 and the partitions 13 are combined to form a holding chamber for accommodating waste; the feed pipe 10 is fixed to the top of the connecting plate 11 for waste to enter the holding chamber.

[0035] like Figure 1-Figure 3 As shown, the pressure plate 9 is located above the separation box 5 and connected to the output end of the hydraulic press. A pressure block 7 is fixed to the bottom surface of the pressure plate 9. The pressure block 7 penetrates the connecting plate 11 and is slidably connected to the accommodating chamber. The shape of the pressure block 7 is closely matched with the inner wall of the accommodating chamber. The pressure plate 9 is located above the separation box 5 and is connected to the output end of the hydraulic press, and the hydraulic press provides pressure. When the hydraulic press is working, it will first drive the pressure plate 9 to move downward, so that the pressure block 7 enters the receiving chamber and squeezes the waste in the receiving chamber; after the waste in the receiving chamber is compressed and discharged, the hydraulic press will drive the pressure plate 9 to move upward, so that the pressure block 7 is pulled out from the receiving chamber upward.

[0036] like Figure 6-Figure 12As shown, the driving structure includes a rotating shaft 14, which is located between the connecting plate 11 and the feed pipe 10, one end of the rotating shaft 14 passes through the wall of the separation box 5 and is rotatably connected to the separation box 5, a plurality of first worms 18 are sleeved on the rotating shaft 14 at equal intervals, a one-way bearing 19 is provided between the inner wall of the first worm 18 and the outer wall of the rotating shaft 14, a plurality of first worm wheels 20 are rotatably installed on the upper surface of the connecting plate 11, the number of the filter screen 12, the first worm 18 and the first worm wheel 20 are equal, and the first worm wheel 20 is fixedly connected to the coaxial line of the filter screen 12, the first worm 18 is matched with the first worm wheel 20, a ring gear 15 is sleeved on the end of the rotating shaft 14, a spring 16 is provided between the ring gear 15 and the rotating shaft 14, a plurality of slide grooves 8 are fixedly connected to the outer wall of the separation box 5, a rack 6 is slidably matched in the slide groove 8, the rack 6 matches the ring gear 15, and the top of the rack 6 is fixedly connected to the bottom surface of the pressure plate 9.

[0037] After the pressing block 7 is drawn out from the accommodating chamber, the driving structure drives the filter screen 12 to rotate, and its working principle is as follows: When the hydraulic press drives the pressure plate 9 to move downward, the rack 6 will also move downward in the slide groove 8, and the rack 6 will drive the ring gear 15 to rotate. The rotation of the ring gear 15 will be driven by the spring 16. Due to the presence of the one-way bearing 19, at this time, the rotation of the shaft 14 will only idle, and will not drive the first worm 18 to rotate.

[0038] When the hydraulic press drives the pressure plate 9 to move upward, the rack 6 will also move upward in the slide groove 8, and the rack 6 will drive the ring gear 15 to rotate in the opposite direction. During the reverse rotation of the ring gear 15, since the pressure block 7 is located in the accommodating chamber and abuts against the filter screen 12, the filter screen 12 is limited by the pressure block 7 and cannot rotate. At this time, the first worm wheel 20 fixed to the filter screen 12 and the first worm 18 matched with the first worm wheel 20 will also be unable to rotate. Because of the presence of the one-way bearing 19, the first worm 18 and the rotating shaft 14 are also fixedly connected. Therefore, during the reverse rotation of the ring gear 15, only the mainspring 16 will be charged, and the rotating shaft 14 will not be driven to rotate in the opposite direction. After the pressure block 7 is pulled out from the accommodating chamber, the restriction of the pressure block 7 on the filter 12 is released. At this time, the elastic potential energy accumulated in the spring 16 will drive the rotating shaft 14 to rotate in the opposite direction. The rotating shaft 14 will drive the first worm 18 to rotate in the opposite direction through the one-way bearing 19. The reverse rotation of the first worm 18 will drive the first worm wheel 20 to rotate. The rotation of the first worm wheel 20 will drive the filter 12 to rotate.

[0039] After the elastic potential energy of the mainspring 16 is released, the filter 12 rotates by an arc of [2nπ+π, (n=0, 1, 2, 3...)], for example, when n=0, the filter 12 rotates by an arc of π; when n=1, the filter 12 rotates by an arc of 3π.

[0040] During the rotation of the filter 12, the impurities in the filter holes of the filter 12 will also rotate accordingly. The impurities will perform centrifugal motion under the action of centrifugal force, so that the impurities will be discharged from the filter holes to prevent the filter 12 from being blocked. In addition, after the rotation of the filter 12 is completed, the two sides of the filter 12 will be swapped. The outer side of the original filter 12 will be transferred to the accommodating chamber, and the side originally located in the accommodating chamber will be transferred to the outer side of the accommodating chamber. When the filter 12 with the inner and outer sides swapped is used for the subsequent waste compression work, the sewage squeezed out of the waste will flush the filter holes originally attached to the inner side of the filter 12 to complete the backwashing work of the filter 12.

[0041] like Figure 11-Figure 18 As shown, a vibration-generating structure is provided in the partition 13 to make the filter screen 12 vibrate, and the vibration-generating structure includes a long shaft 23. A mounting groove 22 is vertically opened in the partition 13. The long shaft 23 is vertically arranged in the mounting groove 22. The top end of the long shaft 23 passes through the connecting plate 11 and is rotatably connected to the connecting plate 11. The top end of the long shaft 23 is coaxially fixed with a second worm gear 21. A second worm gear 17 is provided between two adjacent first worm gears 18. The second worm gear 17 is coaxially fixed to the outer wall of the rotating shaft 14. The second worm gear 17 is coaxially fixed to the outer wall of the rotating shaft 14. The worm wheel 21 matches the second worm 17, and through holes 28 are opened on the two arc surfaces on both sides of the partition 13. A knock hammer 25 is slidably fitted in the through hole 28. The knock hammers 25 on the two arc surfaces of the partition 13 are connected by a spring 26. A slide rod 27 is vertically fixed to the bottom of the knock hammer 25. A rotating ring 24 is fixed on the long axis 23, and a plurality of tooth blocks are fixed on the inner wall of the rotating ring 24. The slide rod 27 is slidably fitted with the rotating ring 24 and rests against the inner wall of the rotating ring 24.

[0042] When the rotating shaft 14 rotates, the rotating shaft 14 will drive the second worm 17 to rotate, the rotation of the second worm 17 will drive the second worm wheel 21 to rotate, the rotation of the second worm wheel 21 will drive the long shaft 23 to rotate, the rotation of the long shaft 23 will drive the rotating ring 24 to rotate, the rotation of the rotating ring 24 will force the sliding rod 27 to vibrate through the tooth blocks on the inner wall, and the knocking hammer 25 fixedly connected to the sliding rod 27 will also vibrate. During the vibration process, the knocking hammer 25 will be pressed against the surface of the filter 12 by the elastic force of the spring 26 to knock on the filter 12, so that the filter 12 vibrates to shake off impurities in the filter holes of the filter 12.

[0043] Workflow and working principle: When solid-liquid separation of waste is carried out, the steps are as follows: S1: First, the bottom plate 4 is driven by the scissor lift 3 to seal on the bottom surface of the separation box 5, and then the waste is loaded into the receiving chamber from the feed pipe 10; S2: Start the hydraulic press. When the hydraulic press works, it first drives the pressure plate 9 to move downward, so that the pressure block 7 enters the receiving chamber to squeeze the waste in the receiving chamber. After the waste is pressed, the sewage inside is squeezed out, and the sewage is discharged from the filter holes of the filter screen 12 into the space between the inner wall of the separation box 5 and the outer wall of the receiving chamber, and then discharged to the outside through the drainage pipe 501 at the bottom of the separation box 5; During the downward movement of the pressure plate 9, the rack 6 will also move downward in the slide groove 8, and the rack 6 will drive the ring gear 15 to rotate. The rotation of the ring gear 15 will be driven by the spring 16. Due to the presence of the one-way bearing 19, at this time, the rotation of the rotating shaft 14 will only drive the second worm 17 to rotate, and the rotation of the second worm 17 will drive the second worm gear 21 to rotate. The rotation of the second worm gear 21 will drive the long shaft 23 to rotate, and the rotation of the long shaft 23 will drive the rotating ring 24 to rotate. The rotation of the rotating ring 24 will force the slide bar 27 to vibrate through the tooth block on the inner wall, and the knocking hammer 25 fixedly connected to the slide bar 27 will also vibrate. During the vibration process, the knocking hammer 25 will be pressed against the surface of the filter screen 12 by the elastic force of the spring 26 to knock on the filter screen 12, so that the filter screen 12 vibrates to shake off impurities in the filter holes of the filter screen 12.

[0044] S3: After the waste is compressed, the scissor lift 3 drives the bottom plate 4 to move downward, so that the bottom plate 4 is removed from the bottom of the separation box 5. After the bottom of the separation box 5 is opened, the compressed waste inside is discharged from the bottom of the separation box 5 under the action of gravity and the pressure of the pressing block 7; S5: After the compressed waste is discharged, the hydraulic machine drives the pressure plate 9 to move upward, so that the pressure block 7 is pulled upward from the accommodating chamber; During the upward movement of the pressure plate 9, the rack 6 will also move upward in the slide groove 8, and the rack 6 will drive the ring gear 15 to rotate in the opposite direction. During the reverse rotation of the ring gear 15, since the pressure block 7 is located in the accommodating chamber and abuts against the filter screen 12, the filter screen 12 is limited by the pressure block 7 and cannot rotate. At this time, the first worm wheel 20 fixed to the filter screen 12 and the first worm 18 matched with the first worm wheel 20 will also be unable to rotate. Because of the presence of the one-way bearing 19, the first worm 18 and the rotating shaft 14 are also fixedly connected. Therefore, during the reverse rotation of the ring gear 15, only the mainspring 16 will be charged, and the rotating shaft 14 will not be driven to rotate in the opposite direction.

[0045] S6: After the pressure block 7 is pulled out from the accommodating chamber, the restriction of the pressure block 7 on the filter 12 is released. At this time, the elastic potential energy accumulated in the spring 16 will drive the rotating shaft 14 to rotate in the opposite direction. The rotating shaft 14 will drive the first worm 18 to rotate in the opposite direction through the one-way bearing 19. The reverse rotation of the first worm 18 will drive the first worm wheel 20 to rotate. The rotation of the first worm wheel 20 will drive the filter 12 to rotate.

[0046] After the elastic potential energy of the spring 16 is released, the filter 12 rotates by an arc of [2nπ+π, (n=0,1,2,3...)]; During the rotation of the filter 12, the impurities in the filter holes of the filter 12 will also rotate accordingly. The impurities will perform centrifugal motion under the action of centrifugal force, so that the impurities will be discharged from the filter holes to prevent the filter 12 from being blocked. In addition, after the rotation of the filter 12 is completed, the two sides of the filter 12 will be swapped. The outer side of the original filter 12 will be transferred to the accommodating chamber, and the side originally located in the accommodating chamber will be transferred to the outer side of the accommodating chamber. When the filter 12 with the inner and outer sides swapped is used for the subsequent waste compression work, the sewage squeezed out of the waste will flush the filter holes originally attached to the inner side of the filter 12 to complete the backwashing work of the filter 12.

[0047] Compared with the prior art, the waste solid-liquid separation and treatment device with a filter press structure provided by the present invention can, during operation, flip the filter screen 12 after each waste compression is completed, and use the centrifugal force generated during the flipping of the filter screen 12 to clean the impurities in the filter holes. After the flipping is completed, the sewage generated by the subsequent waste compression is used to backwash the filter holes, which saves the time required for disassembling and cleaning the filter screen 12 and improves the treatment efficiency of solid-liquid separation of waste.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
