Detailed Implementation

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] Example 1:

[0032] Please refer to Figures 1-8 A novel wastewater filtration device for pig farms, comprising:

[0033] The conveying tank 1 has a separation plate 2 arranged along its length inside. The upper part of the separation plate 2 is set as a residual water conveying channel, and the lower part of the separation plate 2 is set as a liquid return channel.

[0034] The interior of the conveying trough 1 is also equipped with a filter grid 3, which is located at the end of the separation plate 2 and is used for the initial solid-liquid separation of the residual water. It can be seen that the residual water of the pig farm can be conveyed through the conveying trough 1. The separation plate 2 divides the conveying trough 1 into upper and lower channels, and the filter grid 3 is set at the position where the two channels are connected at the end of the separation plate 2, thereby achieving the initial solid-liquid separation effect of the residual water.

[0035] Specifically, the filter grid 3 includes a grid frame assembly 4. A grid fixing plate 5 is detachably installed at one end of the grid frame assembly 4 near the separation plate 2. The grid fixing plate 5 is located below the end of the separation plate 2, and the top of the grid fixing plate 5 is attached to the bottom of the separation plate 2. A filter guide plate 6 is fixedly connected to the other end of the grid frame assembly 4. A protrusion is provided at the upper end of the filter guide plate 6, and the protrusion is located at the end of the grid frame assembly 4 away from the grid fixing plate 5.

[0036] Furthermore, in order to achieve the fixing effect of the filter grid 3, L-shaped fixing brackets 12 are fixedly connected to the grid fixing plate 5 near the end. The upper part of the L-shaped fixing bracket 12 is fixedly connected to the inner wall of the conveying trough 1 by fixing screws 13.

[0037] It can be seen that by the fit between the top of the grid fixing plate 5 and the bottom of the separation plate 2, and by the fixing of the grid fixing plate 5 to the inner wall of the conveying tank 1 through the L-shaped fixing bracket 12, the grid fixing plate 5 is firmly and stably fixed. When the residual water at the top of the separation plate 2 flows to the top of the filter grid 3, the grid frame assembly 4 achieves the initial solid-liquid separation of the residual water. The liquid in the residual water passes through the grid frame assembly 4 and flows towards the liquid return channel after being guided by the filter guide plate 6. The solid part that is blocked continues to slide along the length of the grid frame assembly 4 until it falls from the top of the grid frame assembly 4, and then continues to slide in the opposite direction of the liquid return channel inside the conveying tank 1. The filter guide plate 6 can effectively block the solid part.

[0038] Example 2:

[0039] The novel wastewater filtration device for pig farms provided in Example 1 has been further optimized, specifically, as follows: Figures 4-6 As shown, the grid frame assembly 4 includes an upper grid frame 7 and a lower grid frame 8. The upper grid frame 7 is located above the lower grid frame 8. The gap of the upper grid frame 7 is larger than the gap of the lower grid frame 8. Both the upper grid frame 7 and the lower grid frame 8 are arranged at an angle. The lower end of the upper grid frame 7 and the lower grid frame 8 is the end closer to the filter guide plate 6.

[0040] Furthermore, in order to facilitate the separation of the grid frame assembly 4 from the grid fixing plate 5, the upper grid frame 7 and the lower grid frame 8 are both U-shaped at the ends near the grid fixing plate 5. The upper and lower end faces of the grid fixing plate 5 are respectively provided with a first fastening groove 10 and a second fastening groove 11. The end of the upper grid frame 7 is fastened to the grid fixing plate 5 through the first fastening groove 10, and the end of the lower grid frame 8 is fastened to the grid fixing plate 5 through the second fastening groove 11.

[0041] Through the above structural design, large solid blocks can be blocked by the upper grid frame 7, and small solid blocks can be blocked by the lower grid frame 8. Since both the upper grid frame 7 and the lower grid frame 8 are inclined, the blocked solid blocks can slide along the length of the grid frame assembly 4 to the lower end. The first and second fastening slots 10 and 11 opened on the upper and lower sides of the grid fixing plate 5 enable the upper grid frame 7 and the lower grid frame 8 to be quickly fastened or separated from the grid fixing plate 5, thereby facilitating the connection or separation of the grid fixing plate 5 and the grid frame assembly 4.

[0042] Example 3:

[0043] The novel wastewater filtration device for pig farms provided in Example 1 has been further optimized, specifically, as follows: Figures 8-9 As shown, it also includes a cleaning rack 14 for cleaning the area above the filter guide plate 6 and below the grid frame assembly 4.

[0044] Furthermore, the cleaning frame 14 includes two L-shaped support frames 15. The lower ends of the two L-shaped support frames 15 are fixedly connected by a scraping strip 16, and the upper ends of the two L-shaped support frames 15 are fixedly connected by a gripping rod 18. Connecting slots 17 are provided on the sides of the two L-shaped support frames 15 near the L-shaped fixing frame 12. The L-shaped support frames 15 are fastened to the fixing screws 13 on the L-shaped fixing frame 12 through the connecting slots 17.

[0045] With the above structural design, by pulling the gripping rod 18, the L-shaped support frame 15 and the scraping strip 16 can be driven to scrape and clean the surface of the filter guide plate 6. After use, the cleaning frame 14 can be placed by connecting the buckle groove 17 and engaging with the fixing screw 13 on the L-shaped fixing frame 12.
