Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, and in particular to a waste residue filtering device for rural sewage treatment. Background Art

[0002] In rural areas, due to the relatively dispersed population distribution, garbage collection and treatment often rely on fixed garbage disposal points. These disposal points, as centralized storage places for rural domestic garbage, carry a large amount of daily waste. There are many types of domestic garbage, including kitchen waste, plastic packaging, paper products, and various types of waste, including packaging containing liquids, such as beverage bottles, seasoning packets, food boxes, etc. If the liquid garbage in these packaging is not properly handled, it will be mixed with solid waste, causing a series of environmental problems.

[0003] In order to cope with the challenges brought by the mixing of solid and liquid waste, traditional rural waste treatment devices often use simple filtering devices for preliminary separation. However, most of these filtering devices are simple in design and mainly based on filter mesh structures, which have the problem of low filtering efficiency. Traditional filter mesh structures can only intercept larger solid particles, but it is difficult to effectively discharge liquid waste mixed in the packaging. This causes liquid waste to mix with solid waste for a long time, exacerbating the corruption and stench of the waste.

[0004] Therefore, the present application proposes a waste residue filtering device for rural sewage treatment to solve the above problems. Summary of the invention

After the extrusion is completed, the rotating rod 12 is driven to rotate under the action of the conveying motor 11, and then the solid garbage on the conveyor belt 8 is conveyed from the first output port 9 and the second output port 10 to the conveyor belt collection box 22. During the conveying process, the cleaning roller 19 is driven to rotate under the cooperation of the driving gear 14 and the driven gear 13, and then the cleaning brush 20 is used to clean the residues at the position of the first filter hole 16 on the conveyor belt 8 to prevent the first filter hole 16 from being blocked. While the cleaning roller 19 is rotating, the cleaning comb 21 is used to clean the impurities mixed in the cleaning brush 20, and the impurities slide down along the cleaning comb 21 into the collection box 22. When it is necessary to take out the solid garbage, open the second protection door 6, and the lifting motor 41 drives the lifting screw rod 42 to rotate. Through the cooperation of the lifting screw rod 42 and the lifting plate 43, the lifting plate 43, the connecting frame 40 and the collection box 22 are driven to move upward. When it moves to the upper port position of the collection box 4, the solid garbage can be cleaned. The third filter hole 23 opened on the lower side wall of the collection box 22 is convenient for static water filtration of the garbage after extrusion treatment. When the residual liquid in the waste residue flows into the collection box 4 through the third filter hole 23 under the action of gravity, after the waste water in the filter box 1 is discharged from the discharge pipe 7, the waste water at the bottom of the collection box 4 enters the filter box 1 through the first water passing hole 24 and the second water passing hole 25, so as to avoid the accumulation of waste water in the collection box 4.
