Description

Technical Field

[0001] The utility model relates to the technical field of domestic sewage treatment equipment, in particular to domestic sewage treatment equipment with a multi-layer filtering structure. Background Art

[0002] Domestic sewage refers to sewage generated by residential life, commercial activities and general industrial activities, which contains various organic wastes, solid wastes, chemical substances and microorganisms. The main sources include domestic sewage, sewage from commercial buildings (such as restaurants, shopping malls, etc.), sewage from office places, and sewage from medical and educational institutions. Domestic sewage contains various solid particles, such as residues, sediments, fibers, paper, etc. If these particles are not removed, they will cause blockage to subsequent treatment equipment and pipelines, affecting the treatment effect and equipment life. It also contains a large amount of suspended matter, such as suspended solids, planktonic bacteria, etc. These suspended substances can be effectively removed through filtration treatment equipment to improve the water purification effect.

[0003] Traditional domestic sewage treatment equipment mostly uses a single-layer filter and activated carbon to filter and treat sewage. It is relatively simple, with low operation and maintenance costs. The equipment structure is relatively simple and easy to operate and manage. It can effectively filter solid particles in sewage, such as fiber, paper, plastic, etc., to prevent these particles from entering subsequent treatment units and causing blockage or affecting the treatment effect.

[0004] However, traditional domestic sewage treatment equipment, single-layer filter and activated carbon may not be able to completely remove all pollutants in sewage, especially tiny particles and soluble substances. It is not suitable for treating high-concentration and large-flow sewage and requires additional pretreatment or subsequent treatment processes. Therefore, a domestic sewage treatment equipment with a multi-layer filtration structure is proposed to solve the above problems. Utility Model Content

[0032] Specifically, the filter placement plate 8 is placed inside the slider 13, and then the filter units such as the activated carbon layer 9, the anthracite filter layer 10 and the quartz sand layer 11 can be placed on the top of the filter placement plate 8. The filter placement plate 8 can achieve a balancing effect on the filter device to ensure that the water flows evenly through each filter unit and prevent the filter net from tilting, resulting in excessive or insufficient filtering effects in certain areas. This helps to improve the overall filtration efficiency and ensure the consistency of water quality. The filter device is then placed inside the filter tank 1 through the slider 13 and kept fixed. At the same time, the device can be taken out by the movable hook 12. The design that can be quickly taken out and processed makes the maintenance and cleaning of the equipment more convenient and quick.

[0036] Specifically, the slide column 19 is moved to the inside of the limiting groove 18, and then the inverted cone filter 17 is rotated, and the slide column 19 is driven to rotate by the inverted cone filter 17 to fix it, and then the protective door 2 is closed, and the motor 22 is started, and the cleaning rod 20 is driven to rotate by the motor 22 to clean the filter material on the outer wall of the cone filter 23 to prevent solid particles from accumulating on the net, reduce the risk of blockage and obstruction, help to extend the service life of the equipment and maintain its normal operation, and can easily disassemble and clean the various components of the equipment, so as to facilitate maintenance and maintenance of the equipment and ensure the good operation of the equipment. The cone can provide a larger filtration area, thereby improving the filtration efficiency, which means that more fluids or gases can be processed in the same time, and the slope can be replaced to drop the filter material to the bottom to reduce clogging of the filter.

[0037] Working principle: Place the filter placement plate 8 on the top of the slidingly connected rotating rod 15, then place the appropriate filter unit on the top of the filter placement plate 8, then place the rotating connected slider 13 inside the slidingly connected filter tank 1 by moving the hook 12, then move the inverted cone filter 17, and drive the fixedly connected sliding column 19 to move to the inside of the limiting groove 18 through the inverted cone filter 17, then rotate the inverted cone filter 17, and drive the fixedly connected sliding column 19 to rotate and fix in the limiting groove 18 of its sliding connection through the inverted cone filter 17, then close the protective door 2, lock it through the lock 3, and then discharge the sewage through the injection port 4, and at the same time start the motor 22, and drive the fixedly connected The cleaning rod 20 rotates to clean the filtered material that has not fallen off the surface of the conical filter 23. The sewage passes through the conical filter 23, the discharge port 24 and the inverted cone filter 17 to filter large particles, and places them directly on the finer filter screen to cause blockage. The water source is then completely filtered through the bottom filter unit, and the filtered water source is then discharged through the water outlet 7.
