Description

Technical Field

[0001] The present invention relates to the technical field of domestic sewage in mountain villages, and in particular to a device for collecting and purifying domestic sewage in mountain villages. Background Art

[0002] The treatment and management of domestic sewage in mountain villages is crucial to protecting the ecological environment of mountain villages. Domestic sewage in mountain villages mainly comes from daily life, including oily and food residue sewage generated in the kitchen; and washing sewage generated by laundry, bathing, etc., which are usually discharged in a dispersed manner.

[0003] The terrain of mountain villages is complex and residents are relatively scattered. The amount of sewage is generally small and the discharge is uneven, so centralized sewage treatment is required. Sewage is usually filtered, slag collected, decomposed and purified by microorganisms, etc. Due to insufficient electricity and tight electricity in mountain villages, in the process of using microorganisms to treat filtered sewage, conventional electricity-based oxygen supplementation often consumes excess electricity and equipment, and requires the use of multiple motors in combination to treat sewage, which consumes a lot of electricity and is more inconvenient to maintain.

[0012] Beneficial effects of the present invention: 1. When the motor of the present invention drives the crankshaft to work, the stirring blades stir the sewage to prevent sedimentation, and drives the sliding seat to slide back and forth, compressing and stretching the telescopic airflow. When the telescopic airbag is compressed, the internal gas is sent from the air supply pipe into the sewage to replenish oxygen for the microorganisms. When the airbag is extended, the gas is replenished inside itself. In this way, while the motor drives the stirring blades to stir the sewage to disperse the microorganisms and prevent sedimentation at the bottom, it drives the telescopic airbag to compress and extend reciprocally, and sends air from the air supply pipe into the treatment pool to mix with the flowing sewage, so as to mechanically replenish oxygen for the microorganisms. This can solve the problem of static sedimentation of sewage and the problem of insufficient oxygen supply to microorganisms, and reduce power loss while treating wastewater in an environmentally friendly manner.

[0013] 2. Microorganisms pass through the living net from the inside to the outside until they attach to the inner circle of the carrier, the middle circle of the carrier and the outer circle of the carrier to live, dividing the inside of the treatment pool into multiple annular areas for microbial treatment, which refines the sewage treatment and has a good treatment effect. In the process of the stirring blade stirring the sewage, the sewage treatment flow state inside the treatment pool exchanges positions between the inner circle of the carrier, the middle circle of the carrier and the outer circle of the carrier, and is dynamically decomposed and treated by microorganisms in the three areas, thereby improving the overall sewage treatment efficiency. When the stirring blade rotates to stir the sewage inside the treatment pool, it drives the installation rod to rotate, and the anti-collision rod rotates to drive the three cleaning brushes to rotate, cleaning the living nets at the upper and lower ends of the inner circle of the carrier, the middle circle of the carrier and the outer circle of the carrier to avoid clogging of the living net, so that sewage and microorganisms can pass through to form an annular area.

[0014] 3. When the sliding seat slides back and forth to compress and extend the telescopic airbag to replenish oxygen inside the sewage and replenish air inside itself, the sliding block is driven to slide back and forth on the fixed rail, so that the air supply pipe slides down into the sewage and slides up out of the sewage. That is, when the telescopic airbag is compressed and deflated, the air supply pipe slides down and inserts into the sewage to replenish oxygen in the pool. When the telescopic airbag is extended and air is taken in, the air supply pipe slides up out of the sewage to prevent too much sewage from entering the air supply pipe. In this way, the air supply pipe can be freely retracted and released during the process of replenishing oxygen in the pool. BRIEF DESCRIPTION OF THE DRAWINGS

In the process of the stirring blade 24 stirring the sewage, the sewage treatment flow state inside the treatment pool 1 exchanges positions between the inner ring 61 of the carrier, the middle ring 62 of the carrier and the outer ring 63 of the carrier, and is dynamically decomposed and treated by microorganisms in the three areas, thereby improving the overall sewage treatment efficiency. The materials of the inner ring 61, the middle ring 62 and the outer ring 63 of the carrier can be selected from polyurethane foam, which has a porous structure and high porosity, and microorganisms can grow and reproduce inside and on its surface.

[0024] In this embodiment, see Figure 4The stirring blade 24 is equipped with a cleaning assembly 5, and the cleaning assembly 5 includes a mounting rod 53, which is fixed at one end of one of the stirring blades 24, and the end of the mounting rod 53 is fixedly connected to the anti-collision rod 52, and the lower end of the anti-collision rod 52 is fixedly connected to three cleaning brushes 51 with increasing lengths, and the three cleaning brushes 51 are respectively fitted with the inner sides of the three living nets 64, and the anti-collision rod 52 has an L-shaped structure on one side and a U-shaped structure on the other side to avoid touching the air supply pipe 33; when the stirring blade 24 rotates to stir the sewage inside the treatment pool 1, the mounting rod 53 is driven to rotate, and the anti-collision rod 52 is rotated to drive the three cleaning brushes 51 to rotate, cleaning the living nets 64 at the upper and lower ends of the carrier inner ring 61, the carrier middle ring 62 and the carrier outer ring 63, to avoid clogging of the living net 64, so that sewage and microorganisms can pass through to form an annular area.

[0025] Embodiment 3

[0026] Based on the first embodiment, refer to Figure 1 , Figure 2 Figure 3 , Figure 7 The support frame 21 is equipped with a telescopic assembly 4, which includes a fixed rail 43 of an arc structure.

At this time, during the air supply process of the telescopic airbag 35, it is avoided that the air supply pipe 33 is sucked in too much sewage due to the negative pressure inside and affects the deflation. That is, during the compression and deflation process of the telescopic airbag 35, the air supply pipe 33 slides down and inserts the sewage to replenish oxygen in the pool. During the extension and intake process of the telescopic airbag 35, the sewage slides out of the air supply pipe 33 to prevent too much sewage from entering the air supply pipe 33. In this way, the air supply pipe 33 can be freely retracted and released during the process of replenishing oxygen in the pool.

[0028] Working principle: First, the filtered sewage is collected from the main water inlet pipe 7 into the treatment tank 1. The staff puts microorganisms into the sewage tank to mix with the sewage to purify the sewage. The motor 22 works to drive the crankshaft 26 and the stirring blade 24 to rotate at a low speed. The stirring blade 24 rotates to disperse the microorganisms to various parts of the sewage. In the process of the rotation of the stirring blade 24, the internal substances of the sewage are prevented from settling at the bottom of the treatment tank 1. The microorganisms pass through the living net 64 from the inside to the outside until they attach to the carrier inner ring 61, the carrier middle ring 62 and the carrier outer ring 63 to live, and the inside of the treatment tank 1 is divided into multiple annular areas for microbial treatment. When the crankshaft 26 rotates to drive the stirring blade 24 to work and stir the sewage to prevent sedimentation, it drives the connecting rod 38 to move. Under the action of the other end of the connecting rod 38, the sliding seat 36 is driven to slide back and forth inside the fixed frame 31. When the sliding seat 36 slides close to the motor 22, the telescopic airbag 35 is compressed to press the air inside the telescopic airbag 35 into the soft The air in the air supply pipe 33 is sent into the treatment tank 1 to mix with the flowing sewage to supply oxygen to the microorganisms. When the sliding seat 36 slides away from the motor 22, the telescopic airbag 35 is pulled to extend to replenish air inside, so as to prepare for the telescopic airbag 35 to be compressed again. In this way, while the motor 22 drives the stirring blades 24 to stir the sewage to disperse the microorganisms and prevent sedimentation at the bottom, the telescopic airbag 35 is driven to reciprocately compress and extend, and the air is sent from the air supply pipe 33 to the treatment tank 1 to mix with the flowing sewage to supply oxygen to the microorganisms. When the sliding seat 36 slides and stretches the telescopic airbag 35 to inhale air, under the action of the movable rod 44, the sliding block 41 is pulled to slide close to the fixed frame 31, and the sewage is pulled out of the air supply pipe 33 under the action of the movable column 45, so as to avoid the inhalation of too much sewage due to the negative pressure inside the air supply pipe 33 and affect the deflation. Finally, when the sewage treatment is completed, the sewage is discharged through the drain valve 101.
