[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0038] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] The existing sewage treatment device is used by pouring sewage and sludge into a box together, and setting multiple interception nets inside the box to intercept the sludge. The sewage is discharged from the sewage outlet, and the sludge is intercepted by the interception net and enters the pipeline and the collection box for recovery under the action of gravity.

[0040] In the related art, during use, the sludge is usually adhesive and will form hard lumps after drying. The scraper will be stained with sludge when cleaning the interception net. If it is not cleaned in time, it will affect the next use. Manual cleaning by the user is time-consuming and laborious.

[0041] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a sewage treatment equipment. When it is needed, the user only needs to pour the sewage and sludge into the box body 11 through the feed port 12. When the sewage and sludge pass through the interception net 23, large pieces of sludge are intercepted by the first layer of interception net 23, and a small amount of sludge is driven to continue to move downward through the second layer of interception net 23. The interception net 23 continues to filter the sewage and sludge. A very small amount of sludge is driven downward by the sewage into the third layer of interception net 23. The mesh holes of the three layers of interception net 23 are getting smaller and smaller. Therefore, the sludge can be ignored at this time. The user opens the water outlet 13 to complete the discharge of sewage. When the interception net 23 is blocked by sludge, the user turns on the motor 211. The motor 211 controls the screw 213 to rotate through the steering gear 212, so that the moving block 214 moves horizontally, driving the rod body 22 and the scraper 221 to move on the interception net 23, scraping the interception net 23 to scrape off the sludge, and completing the cleaning of the interception net 23.

[0042] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0044] When it is needed, the user only needs to pour sewage and sludge into the box body 11 through the feed port 12. When the sewage and sludge pass through the interception net 23, large pieces of sludge are intercepted by the first layer of interception net 23, and a small amount of sludge is driven to continue to move downward through the second layer of interception net 23. The interception net 23 continues to filter the sewage and sludge, and a very small amount of sludge is driven downward by the sewage into the third layer of interception net 23. The mesh holes of the three layers of interception net 23 are getting smaller and smaller, so the sludge can be ignored at this time. The user opens the water outlet 13 to complete the discharge of sewage. When the interception net 23 is blocked by sludge, the user turns on the motor 211. The motor 211 controls the screw 213 to rotate through the steering gear 212, so that the moving block 214 moves horizontally, driving the rod body 22 and the scraper 221 to move on the interception net 23, scraping the interception net 23 to scrape off the sludge, and completing the cleaning of the interception net 23.

[0045] In some embodiments, the frame 21 is provided with a recovery box 24 that can accommodate the rod 22 and the scraper 221. The recovery box 24 can prevent sludge from pouring down from above and covering the rod 22 and the scraper 221 when not in use, thereby affecting the use of the device.

[0046] In some embodiments, the opposite surfaces of the recovery box 24 and the cleaning box 25 are set to be open. The open opposite surfaces of the recovery box 24 and the cleaning box 25 can provide space for the horizontal movement of the rod body 22.

[0047] In some embodiments, the scraper blade 221 is made of rubber material. The scraper blade 221 made of rubber material is harder than the sludge and has good deformation ability, and can be used in conjunction with the scraper 251 for cleaning.

[0048] In some embodiments, a dust curtain 252 is provided on the cleaning box 25. The dust curtain 252 is divided into two parts that can be connected by magnetic attraction, and can be quickly reset after the rod body 22 passes through, and can prevent sludge from entering the cleaning box 25 when it is not needed.

[0049] In some embodiments, a plurality of guide grooves are provided on the dust curtain 252. The guide grooves can be provided to facilitate the sludge on the scraper 221 to splash onto the dust curtain 252 when being cleaned, and fall down under the action of gravity, and will not adhere to the dust curtain 252 and be difficult to clean, thereby improving the cleaning efficiency.

[0050] In some embodiments, a plurality of trapezoidal teeth are provided on the scraper 251. The top of the trapezoidal teeth is flat, which can prevent the triangular teeth from cutting the scraper 221. At the same time, the trapezoidal teeth can increase the scraping area between the scraper 251 and the scraper 221, which is larger than the scraping area of ​​the rectangular teeth, thereby improving the cleaning efficiency.

[0051] In some embodiments, the scraper 251 is disposed in the middle of the cleaning box 25. Placing the scraper 251 in the middle of the cleaning box 25 can ensure that the rod 22 moves back and forth on the cleaning box 25 for the same distance, ensuring that the front and back sides of the scraper 221 are evenly cleaned.
