Description

Technical Field

[0001] This utility model relates to a wastewater filtration device for animal culling treatment, belonging to the field of animal culling wastewater treatment equipment. Background Technology

[0002] Animal culling generates a large amount of wastewater containing numerous pathogens such as bacteria and viruses (e.g., anthrax and avian influenza). If discharged directly without treatment, this wastewater could spread diseases through water and soil, threatening human and animal health. Therefore, it is essential to treat the wastewater generated during animal culling. To prevent clogging of the wastewater treatment system, pre-filtration equipment is necessary to intercept large suspended particles (such as hair, bone fragments, and visceral residue).

[0003] The filter plates of existing wastewater filtration devices mostly have square or round holes. For example, in a wastewater treatment device for the harmless treatment of dead animals disclosed in patent announcement number CN219752087U, the filter plates in the filter box have round holes. The filter hole coverage area is small, the water flow rate is slow, and thus the filtration efficiency is low. In addition, the scraper can only clean the filter plate in one direction, leaving dead corners for scraping impurities in the other direction of the filter plate, so the cleaning effect on the filter plate is not good. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a filter device for animal wastewater treatment with fast drainage speed and good cleaning effect.

[0005] The animal wastewater filtration device of this utility model includes a filter box. The upper end of the rear side wall of the filter box is provided with an inlet, and the lower end of the front side wall of the filter box is provided with an outlet. A filter plate is slidably connected to the inside of the filter box in the vertical direction. Several strip-shaped filter holes running in the left and right direction are penetrating through the filter plate. The filter plate is connected to a lifting drive assembly. A moving strip is slidably connected to the inside of the filter box in the left and right direction. The moving strip is connected to a scraper drive assembly. A bidirectional scraper is connected to the bottom of the moving strip. Impurity outlets corresponding to the bidirectional scrapers are penetrating through the left and right side walls of the filter box.

[0006] Furthermore, the front and rear side walls of the filter box are perforated with strip-shaped sliding holes, and the moving strip is slidably connected between the two strip-shaped sliding holes.

[0007] Furthermore, the scraper drive assembly includes two handles, which are respectively fixedly connected to both ends of the moving bar.

[0008] Furthermore, the top of the bidirectional scraper is fixedly connected with multiple guide shafts, each guide shaft passes through the moving strip and is slidably connected to the moving strip, each guide shaft has a limiting platform at its upper end, and each guide shaft has a spring sleeved on its outer side between the bidirectional scraper and the moving strip.

[0009] Furthermore, each inner wall of the filter box is provided with a sliding groove, and the filter plate is slidably connected in each sliding groove.

[0010] Furthermore, the lifting drive assembly includes four lifting rods that are fixedly connected to the four corners of the filter plate. Connecting rods are fixedly connected between the two lifting rods on the left and between the two lifting rods on the right. A lifting plate is fixedly connected between the two connecting rods, and the lifting plate is connected to the lifting drive structure.

[0011] Furthermore, the lifting drive structure includes a mounting plate fixedly connected to the top of the filter box, a screw fixedly connected to the mounting plate, a drive nut threaded onto the screw, and the upper end of the screw penetrating the lifting plate.

[0012] Working principle and process:

[0013] During use, the filter plate is positioned at the lower end. Wastewater enters the filter box through the inlet. Under the action of the filter plate, large particles such as hair, bone fragments, and internal organ residue are retained on the plate. The wastewater then passes through the strip-shaped filter holes on the plate, falls to the bottom of the filter box, and is discharged through the outlet. Because the strip-shaped filter holes are long and narrow, the effective leakage area is large, resulting in a faster drainage speed and improved filtration efficiency. Simultaneously, due to the flow characteristics of floating debris, it moves with the water flow in a forward-backward direction, perpendicular to the left-right direction of the strip-shaped filter holes, effectively preventing impurities from passing through. The filter plate has holes to ensure its filtration effect. When the filter plate needs cleaning, the drive nut is turned, and the screw drives the nut to move upward. This, in turn, moves the filter plate upward through the lifting plate, connecting rod, and lifting rod. When the filter plate is raised to the outlet position, its upper surface is in contact with the bottom surface of the bidirectional scraper. Under the action of the spring, the contact effect between the bidirectional scraper and the filter plate is ensured. Then, by holding the two handles and moving them left and right, the bidirectional scraper can be moved left and right through the moving bar, thereby scraping the impurities on the filter plate to the corresponding outlet and discharging them through the outlet.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The animal wastewater filtration device of this utility model has long strip-shaped filter holes with a large effective water leakage area, resulting in faster water flow and improved filtration efficiency. The filter plate can be cleaned by moving the bidirectional scraper left and right, with no dead corners, thus achieving a good cleaning effect. Attached Figure Description

Detailed Implementation

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0022] Example 1:

[0023] like Figures 1 to 4 As shown, the animal wastewater filtration device of this utility model includes a filter box 1. The upper end of the rear side wall of the filter box 1 is provided with an inlet 14, and the lower end of the front side wall of the filter box 1 is provided with an outlet 2. A filter plate 12 is slidably connected to the inside of the filter box 1 in the vertical direction. Several strip-shaped filter holes 13 running in the left and right direction are passed through the filter plate 12. The filter plate 12 is connected to a lifting drive assembly. A moving strip 5 is slidably connected to the inside of the filter box 1 in the left and right direction. The moving strip 5 is connected to a scraper drive assembly. A bidirectional scraper 15 is connected to the bottom of the moving strip 5. The left and right side walls of the filter box 1 are each provided with a waste outlet 19 corresponding to the bidirectional scraper 15.

[0024] In use, the filter plate 12 is positioned at the lower end. Wastewater enters the filter box 1 through the inlet 14. Under the action of the filter plate 12, large particles of impurities such as hair, bone fragments, and internal organ residue in the wastewater remain on the filter plate 12. The wastewater passes through the strip-shaped filter holes 13 on the filter plate 12 and falls to the bottom of the filter box 1, and is discharged through the outlet 2. Because the strip-shaped filter holes 13 are long and narrow, the effective leakage area is large, resulting in a faster drainage speed and thus improving filtration efficiency. At the same time, due to the flow characteristics of floating objects, the floating objects will move forward and backward with the water flow, which is exactly in line with the flow of water. The horizontally oriented strip filter holes 13 are vertical, which can effectively prevent impurities from passing through the strip filter holes 13 and ensure the filtration effect of the filter plate 12. When the filter plate 12 needs to be cleaned, the lifting drive component is activated to drive the filter plate 12 to move upward. When the filter plate 12 is raised to the impurity outlet 19 position, its upper surface is in contact with the bottom surface of the bidirectional scraper 15. Then, the scraper drive component is activated to drive the bidirectional scraper 15 to move left and right, so that the impurities on the filter plate 12 can be scraped off to the corresponding impurity outlet 19 and discharged through the impurity outlet 19.

[0025] Example 2:

[0026] like Figures 1 to 4 As shown, based on Example 1,

[0027] Furthermore, the front and rear side walls of the filter box 1 are perforated with strip-shaped sliding holes 3, and the moving strip 5 is slidably connected between the two strip-shaped sliding holes 3. The moving strip 5 is directionally slidable relative to the filter box 1 through the strip-shaped sliding holes 3. The structure is simple and the operation is stable.

[0028] Furthermore, the scraper drive assembly includes two handles 4, which are respectively fixedly connected to both ends of the moving bar 5. By gripping the handles 4 and applying pushing or pulling force to the handles 4, the moving bar 5 can be driven.

[0029] Furthermore, the top of the bidirectional scraper 15 is fixedly connected with multiple guide shafts 17, each guide shaft 17 passing through the moving strip 5 and slidably connected to the moving strip 5. Each guide shaft 17 has a limiting platform 18 at its upper end, and each guide shaft 17 has a spring 16 sleeved on its outer side between the bidirectional scraper 15 and the moving strip 5. The limiting platform 18 can prevent the guide shaft 17 from falling off the moving strip 5. When the filter plate 12 moves upward and is in contact with the ground of the bidirectional scraper 15, if the filter plate 12 is lifted further, the filter plate 12 can compress the spring 16. Under the reset action of the spring 16, the bidirectional scraper 15 and the filter plate 12 can be better in contact, which is conducive to improving the scraping effect of the bidirectional scraper 15 on impurities.

[0030] Furthermore, each inner sidewall of the filter box 1 is provided with a sliding groove 20, and the filter plate 12 is slidably connected in each sliding groove 20. The directional sliding of the filter plate 12 relative to the filter box 1 is achieved through the sliding groove 20, which has a simple structure and stable operation.

[0031] Furthermore, the lifting drive assembly includes four lifting rods 8 that are fixedly connected to the four corners of the filter plate 12. Connecting rods 9 are fixedly connected between the two lifting rods 8 on the left and between the two lifting rods 8 on the right. A lifting plate 10 is fixedly connected between the two connecting rods 9. The lifting plate 10 is connected to a lifting drive structure. By the action of the lifting drive structure, the lifting plate 10 is driven to move up and down, thereby driving the filter plate 12 to move up and down through the connecting rods 9 and the lifting rods 8.

[0032] Furthermore, the lifting drive structure includes a mounting plate 6 fixedly connected to the top of the filter box 1. A screw 7 is fixedly connected to the mounting plate 6, and a drive nut 11 is threaded onto the screw 7. The upper end of the screw 7 passes through the lifting plate 10. By rotating the drive nut 11, the drive nut 11 moves upward under the action of the screw 7, thereby driving the lifting plate 10 to move upward.
