[0030] 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 protection scope of the present utility model.

[0031] This utility model provides, for example Figure 1-3 The wastewater treatment device for food processing shown includes a filter box 1, an inlet 2, a filtration mechanism 3, and a sealing mechanism 4. Wastewater from food processing is added to the inner cavity of the filter box 1 to filter out food residue. The bottom of the inlet 2 is fixedly connected to the top of the filter box 1 and is connected to an external sewage pipe to transport the wastewater into the inner cavity of the filter box 1. The filtration mechanism 3 is located inside the filter box 1 and is used to filter and clean food residue from the wastewater. The filtration mechanism 3 filters the residue from the wastewater and discharges the liquid. The sealing mechanism 4 is located at the bottom of the filtration mechanism 3 and is used to close the top of the filtration mechanism 3. The sealing mechanism 4 controls the opening and closing of the bottom of the filtration mechanism 3, facilitating the discharge and cleaning of the filtered residue.

[0032] Specifically, the filtration mechanism 3 includes a feed hopper 31, a discharge pipe 32, a first filter screen 33, a second filter screen 34, and a drain pipe 35. The top of the feed hopper 31 is fixedly connected to the inner wall of the filter box 1, and the top of the discharge pipe 32 is fixedly connected to the bottom of the feed hopper 31. Wastewater in the inlet 2 falls downwards into the inner cavity of the feed hopper 31, facilitating the filtration of residues in the wastewater. The bottom of the discharge pipe 32 is fixedly inserted into the middle of the bottom of the filter box 1. The discharge pipe 32 is used for the flow of wastewater, allowing the residues in the wastewater to be filtered out. The slag enters to the bottom of the inner cavity of the discharge pipe 32. Filter screen 33 is fixedly connected to the inner wall of the feed hopper 31. Filter screen 33 is funnel-shaped and is used to filter the residue in the wastewater. The wastewater falls onto filter screen 33, and the liquid flows out through the mesh of filter screen 33. The residue remains on the inner wall of filter screen 33. As the wastewater falls and impacts filter screen 33, the residue enters the inner cavity of the discharge pipe 32. Filter screen 34 is fixedly connected to the discharge pipe 32. The filter screen 34 is arranged in a cylindrical shape. Wastewater falls into the inner cavity of the filter screen 34, and the liquid is discharged through the mesh of the filter screen 34. As the wastewater flows, it carries the residue to the bottom of the inner cavity of the discharge pipe 32. The top of the drain pipe 35 is fixedly connected to the bottom of the filter box 1. The drain pipes 35 are arranged in a ring array at equal intervals. The filtered liquid is discharged through multiple drain pipes 35. Food wastewater falls into the inner cavity of the feed hopper 31 through the inlet 2, impacting the filter screen 34. The liquid passes through the filter screen 34. As wastewater flows out of the mesh of filter screen 33, residue remains on its inner wall. The impact of the falling wastewater on filter screen 33 causes the residue to enter the inner cavity of discharge pipe 32. Wastewater then flows through the inner cavity of filter screen 34, and the liquid is discharged through the mesh of filter screen 34. The flow of wastewater carries the residue to the bottom of the inner cavity of discharge pipe 32, concentrating it at the bottom and preventing blockage of filter screens 33 and 34, thus facilitating cleaning.

[0033] Furthermore, the sealing mechanism 4 includes a fixed seat 41, a sealing block 42, a rubber pad 43, a fixed block 44, and bristles 45. The inner wall of the fixed seat 41 is threadedly connected to the outer wall of the bottom of the discharge pipe 32. The fixed seat 41 is used to install the sealing block 42. The inner wall of the fixed seat 41 has an internal thread. The outer wall of the bottom of the discharge pipe 32 is closed and has an external thread. The bottom end of the sealing block 42 is fixedly connected to the bottom of the inner wall of the fixed seat 41. The sealing block 42 is slidably inserted into the bottom of the inner cavity of the discharge pipe 32. The sealing block 42 moves with the fixed seat 41. By sliding the sealing block 42 into the bottom of the inner cavity of the discharge pipe 32 and rotating the fixed seat 41, the fixed seat 41 is threadedly connected to the bottom of the discharge pipe 32. The sealing block 42 seals the inner wall of the discharge pipe 32 to prevent liquid from flowing out. The rubber pad 43 is connected to the sealing block. The outer wall of the sealing block 42 is fixedly connected, and the outer wall of the rubber pad 43 is in contact with the inner wall of the discharge pipe 32. The elasticity of the rubber pad 43 is used to seal the space between the outer wall of the sealing block 42 and the inner wall of the discharge pipe 32. The bottom end of the fixing block 44 is fixedly connected to the upper surface of the sealing block 42. The fixing block 44 is set in the inner cavity of the discharge pipe 32. The fixing block 44 is long and moves with the sealing block 42. The bristles 45 are evenly distributed and fixedly connected to one side of the outer wall of the fixing block 44. The bristles 45 are in contact with the inner wall of the filter screen 34. The bristles 45 are used to clean the inner wall of the bottom of the filter screen 34. When the fixing seat 41 is rotated and loosened, the sealing block 42 and the fixing block 44 are rotated at the bottom of the discharge pipe 32, which drives the bristles 45 to rotate together. The bristles 45 are used to clean the residue on the bottom of the inner wall of the filter screen 34.

[0034] The feed hopper 31 is located below the water inlet 2. The bottom of the filter box 1 is curved. The fixing base 41 is U-shaped. The first filter screen 33 is embedded in the feed hopper 31. The second filter screen 34 is embedded in the discharge pipe 32. The discharge pipe 32 is located between the drain pipe 35.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
