[0023] This application discloses a waste liquid impurity removal and filtration device. By moving a collection tank to the bottom of a filter tank, and considering the spaced filter plates and sieve plates within the filter tank, when a bottle containing waste liquid is inverted on the filter plates, the waste liquid undergoes preliminary filtration as it passes through the filter plates and enters the space between the filter plates and sieve plates. The preliminarily filtered waste liquid then flows through the sieve plates into the collection tank. A scraping assembly is located between the filter plates and the sieve plates. A sliding block in the scraping assembly is connected to a scraper, and both ends are movable on a traction rod. Therefore, the sliding block drives the scraper to move, scraping away impurities on the sieve plates and preventing impurities from accumulating and reducing filtration efficiency. The cooperation of the filter plates and sieve plates achieves dual filtration of the waste liquid, and the scraping assembly prevents impurity accumulation, thereby improving filtration efficiency and solving the problem of existing filtration devices having only a single layer of filtration, leading to impurity accumulation and poor filtration performance.

[0045] Reference Figures 1-6 A waste liquid impurity removal and filtration device includes a reaction tank 1, a filter box 2, a collection tank 3 and a scraping assembly 4. The filter box 2 is disposed inside the reaction tank 1 and has an opening 21 extending to the outside of the reaction tank 1. The collection tank 3 is movably disposed inside the opening 21 and a portion of the collection tank 3 is located below the filter box 2.

[0046] The filter box 2 is provided with a support part 22, on which a filter plate 23 is movably installed. The filter box 2 is provided with a receiving groove 24, one end of which extends outside the reaction tank 1. A sieve plate 25 is movably installed on the receiving groove 24. The sieve plate 25 is located below the filter plate 23. The movably installed sieve plate 25 can be picked up and replaced with sieve plates 25 of different apertures according to the actual situation. The scraping assembly 4 is used to scrape off impurities on the sieve plate 25.

[0047] The aperture of the sieve plate 25 is smaller than that of the filter plate 23. The sieve plate 25 performs preliminary sieving, and the filter plate 23 performs secondary sieving.

[0048] The scraping assembly 4 is located between the filter plate 23 and the sieve plate 25. The scraping assembly 4 includes a traction rod 41, a slide 42, and a scraper 43. Two sets of traction rods 41 are provided and symmetrically distributed on both sides of the filter box 2. The two ends of the slide 42 are movably mounted on the two sets of traction rods 41. One end of the slide 42 extends to the outside of the filter box 2 and is provided with a handle 421. The scraper 43 is located at the bottom of the slide 42, and the other end of the scraper 43 abuts against the end face of the sieve plate 25. Through the cooperation of the traction rod 41 and the slide 42, the scraper 43 can move relative to the slide 42 along the length of the filter box 2. The traction rod 41 guides the movement of the slide 42 and improves the stability of the slide 42 when it moves.

[0049] Based on the above structure, by moving the collection tank 3 on the opening 21, one end of the collection tank 3 abuts against the end face of the opening 21, thus placing part of the collection tank 3 on the filter box 2. Since the filter box 2 is equipped with spaced-apart filter plates 23 and sieve plates 25, when the waste liquid bottle is inverted on the filter plates 23, the waste liquid can enter between the filter plates 23 and the sieve plates 25. Meanwhile, lumpy raw materials in the waste liquid bottle are blocked by the filter plates 23, preventing them from falling onto the sieve plates 25 and causing blockage. The cooperation of the filter plates 23 and the sieve plates 25 achieves dual filtration of the waste liquid, thereby improving the filtration effect. The filtered waste liquid flows into the collection tank 3 and is then further filtered. After the waste liquid has settled for a period of time, the supernatant is filtered out and collected. Meanwhile, since the scraper assembly 4 is located between the filter plate 23 and the sieve plate 25, when impurities accumulate on the sieve plate 25, the sliding block 42 is moved along the length of the traction rod 41 by the moving handle 421, so that the scraper 43 can scrape off the impurities on the sieve plate 25, thereby avoiding the accumulation of impurities and improving the filtration efficiency. The cooperation between the filter plate 23 and the sieve plate 25 can achieve the effect of dual filtration, and the scraper assembly 4 can scrape off impurities, thereby improving the filtration efficiency and solving the problem of poor filtration effect caused by the existing waste liquid filtration and collection device having only single-layer filtration.

[0050] In one embodiment, reference is made to Figures 1-4 It also includes a pressing component 5, which is used to squeeze some of the solid raw materials in the waste liquid on the filter plate 23 to achieve the pressing effect. The pressing component 5 includes a support bracket 51, a first push rod component 52 and a pressure plate 53. The support bracket 51 is set on both sides of the reaction tank 1, and the first push rod component 52 is set on the top of the support bracket 51. The first push rod component 52 can be any one of the pneumatic push rod, electric push rod and hydraulic push rod in the prior art. The piston end of the first push rod component 52 passes through the support bracket 51 and is connected to the pressure plate 53. The pressure plate 53 is located between the support bracket 51 and the filter plate 23. When solid waste formed by the impurities in the waste liquid accumulates on the filter plate 23, the pressure plate 53 is controlled by the first push rod component 52 to squeeze it, thereby squeezing out the residual water in the solid waste and avoiding damage to the raw materials through the pressing method.

[0051] A squeezing area is formed between the pressure plate 53 and the filter plate 23. The pressure plate 53 is moved relative to the filter plate by the first push rod component 52, so that the range of the squeezing area is increased or decreased.

[0052] In one embodiment, reference is made to Figure 1 and Figure 5The portion of the liquid collection tank 3 located outside the reaction tank 1 is provided with a discharge seat 31. The discharge seat 31 has a discharge port 311 and is connected to the interior of the liquid collection tank 3. The discharge seat 31 has a chute, and a baffle 312 is movably installed on the chute. By moving the baffle 312 in the chute, the baffle 312 can cover or move away from the discharge port 311. The baffle 312 can be set so that the flow of oil in the discharge seat 31 can be controlled by the operator.

[0053] An inclined end 3111 is provided at the connection between the discharge port 311 and the collection tank 3. The inclined end 3111 facilitates the material to flow into the discharge port 311 along the inclined angle of the inclined end 3111. The discharge seat 31 facilitates the operator to clean the waste liquid and impurities remaining at the bottom of the collection tank 3.

[0054] In one embodiment, reference is made to Figure 1 and Figure 5 The collection tank 3 is also equipped with a pusher assembly 6, which includes a second pusher component 61 and a pusher seat 62. The second pusher component 61 is located on the outside of the collection tank 3. The second pusher component 61 can be any one of the pneumatic pusher, electric pusher, and hydraulic pusher in the prior art. The pusher seat 62 is located inside the collection tank 3. The piston end of the second pusher component 61 passes through the collection tank 3 and connects to the pusher seat 62. Through the cooperation of the second pusher component 61, the pusher seat 62 can move relative to the length of the collection tank 3. Since the filtered waste liquid will be separated into supernatant and waste liquid impurities after a period of time in the collection tank 3, after the supernatant is collected, the pusher seat 62 is moved by the second pusher component 61, which can make the pusher seat 62 move towards the discharge seat 31, so that the impurities fall onto the discharge port 311 of the discharge seat 31 and are discharged.

[0055] In one embodiment, reference is made to Figure 1 and Figure 7 A discharge trough 11 is provided on one side of the reaction tank 1. The discharge trough 11 extends into the interior of the filter box 2. The discharge trough 11 has an extension groove 111. The discharge trough 11 is used to discharge impurities on the sieve plate 25.

[0056] An elastic blocking component 7 is provided on the extension groove 111. The elastic blocking component 7 includes an elastic element 71 and a blocking plate 72. One end of the elastic element 71 is connected to the extension groove 111, and the other end is connected to the blocking plate 72. Through the cooperation of the elastic element 71, the blocking plate 72 is moved away from or covers the discharge groove 11. The elastic element 71 drives the blocking plate 72 to move. Since the elastic element 71 itself has the characteristic of elastic deformation, when the elastic element 71 is in the normal state, one end of the blocking plate 72 can be in contact with the end of the discharge groove 11. The surface is closed to prevent liquid in the filter box 2 from overflowing from the discharge slot 11. When it is necessary to clean the impurities on the filter plate 23, pressure is applied to the elastic element 71, causing the elastic element 71 to move the baffle plate 72 away from the discharge slot 11, so that the impurities can be discharged from the discharge slot 11 into the filter box 2. When the pressure applied to the elastic element 71 is released, the elastic element 71 can move the baffle plate 72 to reset, thereby completing the closure of the discharge slot 11.

[0057] The aforementioned elastic element 71 adopts a pressure spring or a telescopic spring as used in the prior art.

[0058] In one embodiment, reference is made to Figure 1 , Figure 4 and Figure 5 The opening 21 has recesses 211 on both sides, and the liquid collection tank 3 has protrusions 32 on both sides corresponding to the recesses 211. By embedding the protrusions 32 into the recesses 211, the liquid collection tank 3 can move relative to the recesses 211 along their length. The recesses 211 and protrusions 32 can guide the liquid collection tank 3 during movement, thereby preventing the liquid collection tank 3 from shifting its position during movement and improving the stability of movement.

[0059] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 A magnetic layer 221 is provided on one side of the support part 22. When the filter plate 23 is installed on the support part 22, the support part 22 is magnetically connected to the filter plate 23 with the cooperation of the magnetic layer 221. In order to avoid the filter plate 23 shaking due to the flow of liquid during the initial filtration of waste liquid, the support part 22 and the filter plate 23 are magnetically connected with the magnetic layer 221. This can improve the firmness of the filter plate 23 during installation. Furthermore, the magnetic connection makes it easier for operators to remove the filter plate 23, thereby improving the flexibility of use.

[0060] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 8The portion of the sieve plate 25 located outside the receiving tank 24 is provided with a limiting part 251. When one end of the sieve plate 25 abuts against the end face of the receiving tank 24, the limiting part 251 abuts against the end face of the reaction tank 1. The setting of the limiting part 251 allows the mesh on the sieve plate 25 to be completely located inside the filter box 2, while a portion is located outside the receiving tank 24. This facilitates the operator to remove the sieve plate 25 through the limiting part 251 after long-term use, thereby enabling subsequent replacement or maintenance of the sieve plate 25.

[0061] In one embodiment, reference is made to Figure 1 and Figure 6 A handle groove 3121 is provided on one side of the baffle 312. The handle groove 3121 allows the operator to pull the baffle 312 to adjust the movement of the baffle 312 on the discharge seat 31, thereby realizing the material discharge operation of the discharge seat 31.
