Description

Technical Field

[0001] This utility model relates to the field of chemical technology, specifically a waste liquid filtration device. Background Technology

[0002] During the production of bio-enzymes, factories generate waste liquid. If the waste liquid is discharged directly into rivers, it will cause eutrophication of the river water and affect water quality. Therefore, the waste liquid needs to be purified before discharge. One important step is to use a filtration device to filter the impurities in the waste liquid.

[0003] A Chinese patent application with publication number CN 114560593 A discloses a waste liquid filtration device, including a second filtration mechanism, a first filtration mechanism, and a separation mechanism. The two ends of the first filtration mechanism are respectively connected to the second filtration mechanism and the separation mechanism, and the second filtration mechanism, the first filtration mechanism, and the separation mechanism are arranged sequentially from high to low. The separation mechanism is used to further adsorb iron-containing metal particles in the waste liquid and separate them from the waste liquid. In this solution, the waste liquid enters the second filtration mechanism, and after preliminary filtration, most of the larger impurities can be filtered out. The waste liquid after preliminary filtration sequentially enters the first filtration mechanism and the separation mechanism to adsorb and recover the iron-containing metal particles in the waste liquid, avoiding waste of resources. Through the two-stage recovery mode of the first filtration mechanism and the separation mechanism, the adsorption and collection effect of iron-containing metal particles can be further improved.

[0004] In existing filtration devices, when sufficient filter residue accumulates inside the device during the filtration of biological enzyme waste liquid, the bolts need to be removed to disassemble and clean the filter structure, resulting in poor ease of cleaning. Therefore, a waste liquid filtration device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a waste liquid filtration device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a waste liquid filtration device, including a stand, a box mounted on the stand, an inlet pipe mounted on the top plate of the box, an outlet pipe mounted on the bottom side of the box, an installation box mounted on the outlet pipe, a rotating rod rotatably mounted on the inner wall of the installation box, an installation component fixedly sleeved around the rotating rod, two symmetrically opened installation slots on the installation component, filter elements placed in the installation slots, a feed inlet on the installation box, a filter hole opened on the bottom plate of the installation component, a worm gear fixedly sleeved on the rotating rod, a fixing block mounted on the bottom side of the installation box, a worm rotatably mounted on the fixing block, the worm and the worm gear meshing with each other, a knob mounted on the worm, a cover plate rotatably mounted on the installation box via a pin, the cover plate being located above the feed inlet, a plate groove opened on the side wall of the box, and a limit groove opened on the side wall of the box. The inner wall of the housing has a slot for holding a filter box. The bottom plate of the filter box is a filter plate. A handle is installed on the side wall of the filter box. A sliding plate is installed in the plate slot. Limiting blocks are symmetrically installed on the side wall of the sliding plate and are installed in the limiting groove. A handle is installed on the outer wall of the sliding plate, and a positioning block is installed on the side wall of the handle. A baffle is installed on the outer wall of the housing by a pin. By moving the sliding plate horizontally, the outlet of the plate slot opens, allowing the filter box to be removed from the plate slot, thus achieving quick disassembly of the filter box. By placing a new filter element into the empty mounting slot and then driving the mounting component to rotate 180°, the new filter element moves to the outlet pipe, while the old filter element moves to the inlet, allowing the filter element to be removed, thus achieving quick replacement of the filter element. This structure simplifies the disassembly of the filter box and the replacement of the filter element, which is beneficial to improving the convenience of cleaning the device.

[0007] Preferably, two support plates are installed on the inner wall of the chamber, and multiple springs are installed on the support plates. Buffer plates are installed on the springs and are located below the inlet pipe. A damper is installed between the support plates and the buffer plates. When the biological enzyme waste liquid enters the chamber through the inlet pipe, it impacts the buffer plates. The springs on the bottom side of the buffer plates work in conjunction with the damper to achieve a buffering effect, reducing the impact force of the waste liquid, avoiding damage to the filter plates, and improving the protection of the device.

[0008] The advantages of this utility model are:

[0009] 1. This utility model achieves quick disassembly of the filter box by horizontally moving the sliding plate and opening the outlet of the plate groove. The filter box can be removed from the plate groove. By placing the new filter element into the empty mounting slot and then driving the mounting component to rotate 180°, the new filter element moves to the outlet pipe, while the old filter element moves to the inlet. The filter element can then be removed, achieving quick replacement. This structure simplifies the disassembly of the filter box and the replacement of the filter element, which is beneficial to improving the convenience of cleaning the device.

[0010] 2. In this invention, biological enzyme waste liquid enters the tank through the inlet pipe, and then the waste liquid impacts the buffer plate. The spring and damper on the bottom side of the buffer plate work together to achieve a buffering effect, thereby reducing the impact force of the waste liquid, avoiding damage to the filter plate, and improving the protection of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-4 As shown, a waste liquid filtration device includes a stand 1, a housing 2 mounted on the stand 1, an inlet pipe 3 mounted on the top plate of the housing 2, an outlet pipe 4 mounted on the bottom side of the housing 2, an installation box 5 mounted on the outlet pipe 4, a rotating rod 6 rotatably mounted on the inner wall of the installation box 5, an installation component 7 fixedly sleeved around the rotating rod 6, two symmetrically opened installation grooves 8 on the installation component 7, filter elements 9 placed in the installation grooves 8, a feed inlet 10 on the installation box 5, and filter holes opened on the bottom plate of the installation component 7. A worm gear 11 is fixedly mounted on the upper part of the mounting box 5. A fixing block 12 is mounted on the bottom side of the mounting box 5. A worm gear 13 is rotatably mounted on the fixing block 12. The worm gear 13 meshes with the worm gear 11. A knob 14 is mounted on the worm gear 13. A cover plate 28 is rotatably mounted on the mounting box 5 via a pin. The cover plate 28 is located above the feed inlet 10. A plate groove 15 is opened on the side wall of the box body 2. A limit groove 16 is opened on the side wall of the box body 2. A slot 17 is opened on the inner wall of the box body 2. A filter box 18 is placed in the slot 17. The bottom plate is a filter plate. A handle 19 is installed on the side wall of the filter box 18. A sliding plate 20 is installed in the plate groove 15. Limiting blocks 21 are symmetrically installed on the side wall of the sliding plate 20. The limiting blocks 21 are installed in the limiting groove 16. A handle 22 is installed on the outer wall of the sliding plate 20. A positioning block 23 is installed on the side wall of the handle 22. A baffle 24 is rotatably installed on the outer wall of the box 2 via a pin. During operation, when the existing filter device filters biological enzyme waste liquid, when enough filter residue accumulates in the device... The bolts need to be removed to disassemble and clean the filter structure, which makes the cleaning of the device inconvenient. The biological enzyme waste liquid enters the box 2 from the inlet pipe 3, and then passes through the filter box 18. The filter plate on the bottom side of the filter box 18 intercepts large particulate impurities in the waste liquid. The filtered waste liquid flows into the outlet pipe 4, and then passes through the filter element 9 in the installation box 5. The filter element 9 intercepts small particulate impurities in the waste liquid. Finally, the filtered waste liquid is discharged from the outlet of the outlet pipe 4, thus achieving the filtration of impurities in the biological enzyme waste liquid.

[0020] When enough filter cake accumulates in the filter box 18, it needs to be disassembled and cleaned. By rotating the baffle 24, the baffle 24 no longer limits the sliding plate 20. Then, pull the handle 22, which drives the sliding plate 20 to move horizontally in the plate groove 15. The outlet of the plate groove 15 opens. At this time, pull the handle 19 of the filter box 18 to remove the filter box 18 from the plate groove 15, thus achieving quick disassembly of the filter box 18. After that, the filter box 18 can be emptied and cleaned.

[0021] When replacing filter element 9, the feed port 10 of mounting box 5 is opened by rotating cover plate 28. Then, the new filter element 9 is placed into the empty mounting slot 8 of mounting component 7 through feed port 10. Then, the knob 14 is turned to drive worm gear 13 to rotate. Worm gear 13 drives worm wheel 11 to rotate. The combination of worm wheel 11 and worm gear 13 has self-locking property. Worm wheel 11 drives rotating rod 6 to rotate. Rotating rod 6 drives mounting component 7 to rotate 180°. At this time, the new filter element 9 moves to the outlet pipe 4, while the old filter element 9 moves to feed port 10. The filter element 9 can be removed, realizing the quick replacement of filter element 9. This structure makes the disassembly of filter box 18 and the replacement of filter element 9 simple and improves the convenience of cleaning the device.

[0022] Please see Figure 5 As shown, two support plates 25 are installed on the inner wall of the housing 2. Multiple springs 26 are installed on the support plates 25, and buffer plates 27 are installed on the springs 26. The buffer plates 27 are located below the inlet pipe 3, and a damper is installed between the support plates 25 and the buffer plates 27. During operation, existing filtration devices cannot protect the filter plates during the filtration of biological enzyme waste liquid. The waste liquid under water pressure can easily impact the filter plates, causing damage to the filter plates and resulting in poor protection of the device. The biological enzyme waste liquid enters the housing 2 through the inlet pipe 3 and then impacts the buffer plates 27. The springs 26 on the bottom side of the buffer plates 27 vibrate, and the springs 26 absorb the impact force through elastic deformation. The springs and dampers work together to achieve a buffering effect. When the waste liquid falls onto the filter plates of the filter box 18, the impact force of the waste liquid is reduced, thus reducing the impact force of the waste liquid and avoiding damage to the filter plates, which helps to improve the protection of the device.

[0023] Working principle: In existing filtration devices, when sufficient filter residue accumulates inside the device during the filtration of bio-enzyme waste liquid, the bolts need to be removed to disassemble and clean the filter structure, resulting in poor cleaning convenience. The bio-enzyme waste liquid enters the housing 2 through the inlet pipe 3, then passes through the filter box 18. The filter plate on the bottom of the filter box 18 intercepts large particulate impurities in the waste liquid. The filtered waste liquid flows into the outlet pipe 4, then passes through the filter element 9 inside the mounting box 5. The filter element 9 intercepts small particulate impurities in the waste liquid, and finally the filtered waste liquid is discharged from the outlet pipe 4, thus achieving impurity filtration of the bio-enzyme waste liquid. When sufficient filter cake accumulates in filter box 18, it needs to be disassembled and cleaned. By rotating baffle 24, baffle 24 no longer limits the sliding plate 20. Then, pull handle 22, which moves the sliding plate 20 horizontally within the plate groove 15, opening the outlet of plate groove 15. At this time, pull handle 19 of filter box 18 to remove filter box 18 from plate groove 15, achieving quick disassembly of filter box 18. Afterward, filter box 18 can be emptied and cleaned. When replacing filter element 9, by rotating cover 28, the feed inlet 10 of installation box 5 is opened, and then the new filter element 9 is placed into the feed inlet 10. The filter element 9 is inserted into the empty mounting slot 8 of the mounting component 7. Then, the knob 14 is turned, which drives the worm gear 13 to rotate. The worm gear 13 drives the worm wheel 11 to rotate. The combination of the worm wheel 11 and the worm gear 13 has a self-locking property. The worm wheel 11 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the mounting component 7 to rotate 180°. At this time, the new filter element 9 moves to the outlet pipe 4, while the old filter element 9 moves to the inlet 10. The filter element 9 can be removed, realizing the quick replacement of the filter element 9. This structure makes it easy to disassemble the filter box 18 and replace the filter element 9, which is beneficial to improving the convenience of cleaning the device. The existing filtration device is suitable for the treatment of biological enzyme waste. During the filtration process, since the filter plate cannot be protected, the waste liquid is prone to impacting the filter plate under water pressure, causing damage to the filter plate and resulting in poor protection of the device. The biological enzyme waste liquid enters the box 2 through the inlet pipe 3, and then impacts the buffer plate 27. The spring 26 on the bottom side of the buffer plate 27 vibrates, and the spring 26 absorbs the impact force through elastic deformation. The spring and the damper work together to achieve a buffering effect. When the waste liquid falls on the filter plate of the filter box 18, the impact force of the waste liquid is reduced, thus reducing the impact force of the waste liquid and avoiding damage to the filter plate, which helps to improve the protection of the device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
