Description

Domestic sewage treatment plant

technical field

The invention relates to the field of sewage treatment, in particular to a domestic sewage treatment device.

Background technique

Cleaning dishes is a very common thing in life. After washing the dishes, there will be a lot of residue left in the cleaning tank. In order to prevent the sewer from being blocked, most of the residues are intercepted in the cleaning tank through the filter screen, and the residue in the filter screen needs to be poured out after each cleaning. , very troublesome; at the same time, due to the small area of the filter screen, the filter screen will be blocked when there are too many residues and the water flow is fast. Manual stirring is required to prevent the mesh from being blocked, and the operation is more cumbersome.

Contents of the invention

The purpose of the present invention is to provide a domestic sewage treatment device which can not block the mesh and can regularly clean the residue.

In order to achieve the above object, the technical solution of the present invention is to provide a domestic sewage treatment device, including a cavity, which is provided with a frame, a feed pipe, a receiving tank, a filter cartridge, a drum, a water pipe and a water tank; The tube and the receiving groove are fixed on the frame and the lower end of the feed pipe is aligned with the receiving groove. The filter cartridge is rotatably installed on the frame and is located on the side of the receiving groove. The end of the receiving groove close to the filter cartridge is in contact with the outer wall of the filter cartridge. ; The wall of the filter cartridge is provided with a filter hole, and a No. 1 gear is fixed at both ends of the filter cartridge; The meshing gear No. 2 has scrapers evenly distributed on the outer cylinder wall of the drum, and the scrapers can contact the outer cylinder wall of the filter cylinder; one end of the water holding pipe is connected with a water outlet pipe and this end is fixed on the frame, and the water holding pipe The other end passes through the filter cylinder and is located in the water storage tank. The outer pipe wall of the water storage pipe cooperates with the inner cylinder wall of the filter cylinder in a gap; The water is introduced into the No. 1 water pump in the effluent tank; a collection box with an open top is arranged directly below the filter cylinder and the drum, and a slide rail is fixed on the side wall of the collection box. On the slide rail, the box bottom of the collection box is provided with a hole; the box bottom of the collection box is provided with a No. 2 water pump capable of introducing water into the outlet pipe.

The technical effect of this scheme is: through the cooperation of the filter cartridge and the water pipe, the residue and water can be separated, and the water can be divided at the same time, and part of the water can be discharged from the room first; The combination of the first gear and the second gear can use another part of the water to provide power to realize the automatic rotation of the filter cartridge, thereby driving the residue to rotate, effectively avoiding the problem of blockage caused by the accumulation of residue, and then using the force of the scraper during the rotation With the impact of water, the residue on the outer wall of the filter cartridge is cleaned to achieve the effect of smooth separation of water and residue; and then another part of the diverted water is discharged from the room under the action of the No. 2 water pump and the collection box, and collected at the same time The box can collect the residue, which solves the problem that the residue needs to be cleaned after each cleaning, and realizes the regular cleaning of the residue, which is more convenient.

Further, the feeding pipe is arranged obliquely, and the lower end of the feeding pipe is in contact with the receiving groove. The technical effect of this scheme is: the inclined setting can prevent the residue from clogging the feeding pipe. In addition, if there is a certain distance between the lower end of the feeding pipe and the receiving groove, the residue will fall to the receiving groove under the action of gravity, and the water will flow along the feed pipe. The direction of the pipe flows to the receiving groove, which will cause residue accumulation. This problem can be effectively solved by making the lower end of the feed pipe contact with the receiving groove.

Further, protrusions are also provided on the outer cylinder wall of the filter cylinder. The technical effect of the proposal is that the protrusion can further ensure the transfer of the residue adhering to the outer wall of the filter cartridge.

Further, a sealing strip is provided at one end of the receiving groove close to the filter cartridge. The technical effect of this solution is that the sealing strip can effectively prevent residues from being stuck between the receiving groove and the outer wall of the filter cartridge, thereby ensuring the normal rotation of the filter cartridge.

Further, the bottom of the collection box is provided with pulleys, and the pulleys are located in the slide rails. The technical effect of the proposal is that the pulley can improve the smoothness of the movement of the collection box, and prevent the residue from entering the slide rail from the hole and affecting the movement of the collection box.

When the above technical solution is adopted, the problem of clogging easily caused by accumulation of residues is effectively avoided, and at the same time, the problem of needing to clean residues after each cleaning is solved.
