[0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other unused water such as initial rain runoff into drainage pipes. It generally refers to water that cannot be recycled after certain technical treatment or water that cannot meet certain standards for purification after primary pollution. In the process of animal husbandry, animals are washed regularly to keep their fur clean, but a large amount of wastewater will be generated after washing. In order to reduce waste, the washing wastewater can be treated and recycled.

[0003] However, the existing multi-stage filtration device for wastewater used for animal washing still has certain problems when used: There is a Chinese patent application number CN210505785U for a livestock and poultry breeding house cleaning wastewater recycling treatment device, which includes a wastewater treatment box, a wastewater discharge bucket is arranged at the top of the wastewater treatment box, and slow flow plates are staggeredly distributed just below the wastewater discharge bucket. A support rod connected to the inner wall of the wastewater treatment box is fixed at the bottom of the slow flow plate. A waste residue storage box is arranged at the bottom of the wastewater treatment box, and a water seepage plate is horizontally fixed at the bottom of the waste residue storage box, and a wastewater cavity corresponds to the bottom of the water seepage plate; 1. The existing wastewater treatment device mainly relies on the filter screen to treat wastewater, but the slow flow structure set therein can only reduce the flow rate of waste residue, but it will still accumulate on the outside of the filter screen, which is prone to filter screen clogging, and over time, the filtration efficiency will gradually decrease; 2. The existing wastewater treatment device is unable to classify, collect and process feces and hair impurities. Animal hair has certain utilization value after being recycled, but the existing treatment device is unable to classify and collect it, and cannot fully utilize this value.

[0004] In view of the above problems, an innovative design was made based on the original multi-stage wastewater filtration device used for animal washing. Summary of the invention

[0005] The object of the present invention is to provide a multi-stage filtration device for wastewater washing of animals, so as to solve the problem mentioned in the above background technology that the filter screen of the existing wastewater treatment device is prone to clogging during wastewater treatment. Although it can be cleaned automatically, the wastewater filtration efficiency will gradually decrease before cleaning, and the washing wastewater contains a large amount of animal hair and cannot be recycled.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a wastewater multi-stage filtration device for animal washing, comprising a support frame and a treatment barrel: A treatment barrel is fixed at the upper end of the support frame, and a liquid inlet pipe is connected to the upper end of the treatment barrel, a liquid inlet conduit is connected to the lower end of the liquid inlet pipe, and the lower end of the liquid inlet conduit extends to the inside of the support frame, a liquid outlet pipe is connected to the bottom end of the treatment barrel, and a sealed box door is hingedly connected to the lower end of the treatment barrel; A guide plate is arranged at the upper end of the processing barrel, and a pre-filter cover is arranged in the middle of the guide plate, a guide bucket is connected to the lower end of the guide plate, and a filter box is arranged at the lower end of the guide bucket, a first slow flow plate is arranged inside the filter box, and a second slow flow plate is arranged at the lower end of the first slow flow plate, and a transmission frame is installed at the upper ends of the first slow flow plate and the second slow flow plate; A transmission rod is connected to the lower end of the processing barrel, and a collection box is arranged outside the transmission rod. A first filter screen is embedded in the side of the collection box, and a liquid inlet groove is opened on the other side of the collection box, and a feed baffle is arranged inside the liquid inlet groove.

[0008] By adopting the above technical solution, through the cooperation of the liquid inlet conduit and the guide cover, wastewater can flow evenly through multiple groups of conducting holes when injected, thereby making the wastewater flow evenly to the surface of the pre-filter cover.

The guide plate is designed in a circular ring shape, and a guide groove is opened at the upper end of the guide plate. The bottom of both sides of the guide groove are connected to the first discharge pipe, and the depth of the left and right ends of the guide groove is greater than the depth in the middle.

[0010] By adopting the above technical solution, larger impurities such as feces can be filtered through the pre-filter cover and roll along the surface of the pre-filter cover to the inside of the guide groove. Due to the different heights inside the guide groove, the larger impurities can flow from the guide groove to the inside of the first discharge pipe.

[0011] Preferably, storage boxes are provided on both sides of the outside of the processing barrel, and the lower end of the storage box is engaged with the processing barrel, the storage box is consistent with the outer wall of the processing barrel, a positioning bolt passes through the upper end of the storage box, and the positioning bolt is threadedly connected to the outer wall of the processing barrel, and the first discharge pipe passes through the processing barrel and extends to the inside of the storage box.

[0012] By adopting the above technical solution, through the cooperation of the first discharge pipe and the storage box, the impurities discharged from the first discharge pipe can be collected into the storage box, and the positioning bolts can fix the storage box to the outside of the processing box, thereby facilitating the quick disassembly and assembly of the storage box to clean the impurities collected inside.

A second discharge pipe is connected to the bottom of the discharge trough, and the end of the second discharge pipe extends to the outside of the processing barrel.

[0016] By adopting the above technical scheme, the impurities generated when the wastewater flows can be collected through the cooperation of the limiting block and the transmission frame, and the transmission frame and the limiting block can be sealed with the openings of the limiting plate respectively. When the electric push rod is extended and retracted, it can push the transmission frame and the limiting block to move.

When the transmission rack moves, the transmission gear, the transmission shaft and the pre-filter cover can be driven to rotate synchronously. When the pre-filter cover rotates, centrifugal force can be generated, which can quickly throw impurities on the surface of the pre-filter cover into the guide groove.

[0022] By adopting the above technical solution, the transmission rod can be driven to rotate by the power motor, and the collection box can be installed on the outside of the transmission rod by utilizing the cooperation between the limit groove and the transmission rod.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the multi-stage wastewater filtration device for animal washing, by being provided with a pre-filtration structure, can collect larger impurities after the wastewater is injected, and can collect them, and cooperate with the slow flow structure to allow the remaining impurities to precipitate and then be collected when the wastewater flows slowly, and can realize autonomous cleaning and discharge of impurities.

[0024] 1. By utilizing the slow flow structure, the internal impurities can be precipitated while the wastewater is flowing, thus reducing the subsequent filtering pressure of the filter, reducing the probability of filter blockage, and avoiding affecting the filtering efficiency of the filter. At the same time, when cleaning the impurities precipitated on the upper end of the slow flow plate, the gear rack structure drives the pre-filter structure to rotate, and uses centrifugal force to shake and clean the impurities attached to the surface of the pre-filter cover, avoiding clogging and affecting the filtering efficiency; 2. A hair collection structure is provided, and a power motor is used to provide power to drive the rotation. During the rotation, wastewater flows into the collection box and is retained.

The upper end surface of the pre-filter cover 8 is conical in design, and the intercepted impurities can roll downward with the flow of water and fall into the guide groove 9. Because the distance between the guide groove 9 and the first discharge pipe 10 is closer, the depth is deeper, ensuring that after the impurities fall into the guide groove 9, they can gradually move to the first discharge pipe 10 and be discharged to the outside, and fall into the storage box 11 to complete collection.
