Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to an air pollution control device. Background Technology

[0002] Existing water bath vacuum cleaners typically employ a multi-layered, staggered baffle structure to achieve air-water separation. However, this structure has significant drawbacks: when the baffle height is not properly designed, under the negative pressure of the fan, debris and dust easily accumulate in the gaps between the baffles, causing internal blockages; simultaneously, water-insoluble dust is heavily adsorbed into the staggered structure of the baffles, making cleaning difficult and maintenance costs high.

[0003] Furthermore, traditional equipment is prone to overall shaking during operation due to internal water vortex phenomena, affecting operational stability. The lack of effective separation between waste collection and water level monitoring functions leads to inconvenient maintenance and low work efficiency. Utility Model Content

[0007] The upper cylinder is equipped with a spiral separator, including a central cylinder and spiral blades fixed to the outer wall of the central cylinder. The outer edge of the spiral blades is fixed to the inner wall of the upper cylinder to form a spiral channel.

[0008] The outer wall of the middle cylinder is provided with a suction port, and the interior of the middle cylinder is provided with a cyclone separator;

[0009] The lower bucket is equipped with a flow stabilizer and water. The outer wall of the lower bucket is equipped with a secondary water tank that communicates with the lower bucket. The secondary water tank is divided into a water level monitoring tank and a waste disposal tank by a partition.

[0011] As a further technical solution of this utility model: the suction port is located on one side of the cyclone separator.

[0012] As a further technical solution of this utility model: the inner wall of the lower bucket is provided with a baffle, which is located between the water level monitoring tank and the water inlet of the garbage treatment tank.

[0013] As a further technical solution of this utility model: three supporting columns are evenly fixed on the outer periphery of the lower barrel.

[0030] Example 1:

[0031] Reference Figure 1 and Figure 2This utility model discloses an air pollution control device, including a cylindrical body, which is composed of an upper cylinder 1, a middle cylinder 2, and a lower cylinder 3 connected in sequence. In this embodiment, the upper cylinder 1, the middle cylinder 2, and the lower cylinder 3 are connected by flanges to form a continuous processing channel.

[0032] A fan 4 is installed at the top of the upper cylinder 1. The air inlet of the fan 4 is located inside the cylinder, and the air outlet of the fan 4 is used to discharge clean air. In this embodiment, a fan 4 mounting base is provided at the top of the upper cylinder 1, on which the fan 4 is installed. The air inlet of the fan 4 extends into the interior of the upper cylinder 1, and the air outlet is connected to an exhaust pipe. A circular baffle 14 is provided at the bottom air inlet of the fan 4. The circular baffle 14 is fixed to the top wall inside the upper cylinder 1. The diameter of the circular baffle 14 is 20-30% larger than the diameter of the air inlet of the fan 4. In this embodiment, the diameter of the circular baffle 14 is 25% larger than the diameter of the air inlet of the fan 4.

[0033] The upper cylinder 1 is equipped with a spiral separator 5, including a central cylinder 51 and spiral blades 52 fixed to the outer wall of the central cylinder 51. The outer edge of the spiral blades 52 is fixed to the inner wall of the upper cylinder 1 to form a spiral channel 6 for airflow upward. The upper and lower ends of the central cylinder 51 are respectively truncated cones with a cone angle of 30-45° to facilitate smooth airflow and the formation of vortices. The spiral angle of the spiral blades 52 is 45-60°, and the pitch is 200-300mm. In this embodiment, the upper and lower ends of the central cylinder 51 have a cone angle of 35°. The spiral angle of the spiral blades 52 is 55°, the pitch is 250mm, and the outer edge of the spiral blades 52 is welded and fixed to the inner wall of the upper cylinder 1.

[0034] The central cylinder 51 is shaped like a truncated cone, causing the airflow entering the spiral channel 6 to rise in a spiral pattern, preventing blockage. Light dust and moisture will rise in a spiral airflow on the inner wall of the upper cylinder 1 and be thrown upwards by centrifugal force, greatly preventing dust and moisture from entering the fan 4. A circular baffle 14 is installed at the bottom air inlet of the fan 4 to prevent dust-containing moisture from entering the fan 4 and causing damage. Due to the spiral airflow, the dust-containing moisture will rotate repeatedly on the inner wall of the upper cylinder 1. When stopping for cleaning, only a water gun is needed to clean the inner wall of the upper cylinder 1, achieving low maintenance and improving work efficiency.

[0035] The outer wall of the middle cylinder 2 is provided with a suction port 7, which is connected to an external pollution source through a pipe. The middle cylinder 2 is provided with a cyclone separator 8, and the suction port 7 is located on one side of the cyclone separator 8.

[0036] The lower tank 3 contains a flow stabilizer 9 and water. The flow stabilizer 9 includes a central column and 6-8 radially arranged stabilizing blades evenly distributed. A water storage chamber is located at the bottom of the lower tank 3; the water level in the bottom water storage chamber is 2 / 3 of the tank's height. When the blower 4 operates, the presence of the cyclone separator 8 causes a strong vortex in the water within the lower tank 3, which impacts the inner wall of the lower tank 3, causing it to shake and making the machine unstable. The function of the flow stabilizer 9 is to suppress the strong vortex phenomenon, reduce the shaking of the lower tank 3, and improve the stability of the machine's operation.

[0037] The outer wall of the lower bucket 3 is equipped with a secondary water tank 10 that communicates with the interior of the lower bucket 3. The secondary water tank 10 is divided into a water level monitoring tank 12 and a waste disposal tank 13 by a partition 11. The water level monitoring tank 12 is equipped with a water level sensor and a water level gauge. The inner wall of the lower bucket 3 is equipped with a baffle for guiding the flow. The baffle is located between the inlets of the water level monitoring tank 12 and the waste disposal tank 13. The cross-section of the baffle is triangular, and its height is 1 / 2 to 2 / 3 of the height of the inlet. Three support columns 15 are evenly fixed to the perimeter of the outer wall of the lower bucket 3. The bottom of the support columns 15 is equipped with adjustable feet.

[0038] A partition 11 is installed inside the auxiliary water tank 10, dividing it into a water level monitoring tank 12 and a waste disposal tank 13. Both the water level monitoring tank 12 and the waste disposal tank 13 are connected to the cavity inside the lower bucket 3. Since the suction port 7 is located on the side wall of the middle cylinder 2 and to the right of the waste disposal tank 13, during operation, the waste in the water in the lower bucket 3 will enter the waste disposal tank 13 under the action of swirling current, and can be manually cleaned. The water level monitoring tank 12 contains less waste and is mainly used to monitor the water level stored in the lower bucket 3. Furthermore, a baffle is installed on the side wall of the lower bucket 3, located between the water inlet of the water level monitoring tank 12 and the water inlet of the waste disposal tank 13. This arrangement ensures that most of the spiraling waste enters the waste disposal tank 13 and prevents it from entering the water level monitoring tank 12.

[0039] The working process of this utility model is as follows:

[0040] During operation, a certain amount of water is pre-filled into the lower bucket 3. After the fan 4 is started, a negative pressure is formed inside the equipment, and the dust-laden airflow enters the water in the lower bucket 3 through the suction port 7. Heavier waste settles in the water under gravity, while lighter dust and water vapor rise under the negative pressure.

[0041] As the airflow passes through the cyclone separator 8, large dust particles are separated and fall. The airflow then enters the spiral separator 5, where it forms a rotating airflow within the spiral channel 6. Water droplets and dust particles are thrown against the inner wall of the upper cylinder 1 by centrifugal force and fall along the wall. The purified air is then discharged through the fan 4, achieving the purification of hazardous waste, toxic gases, and dust.

[0042] When the water flow forms a vortex in the lower bucket 3, the flow stabilizer 9 effectively suppresses the generation of eddies and maintains stable operation of the equipment. Under the action of the vortex, the garbage moves towards the auxiliary water tank 10. Under the action of the guide baffle, most of the garbage enters the garbage treatment tank 13, and the water flows into the water level monitoring tank 12 for monitoring purposes.

[0043] After shutdown, the garbage in the garbage disposal tank 13 can be cleaned through the opening above the garbage disposal tank 13, and the equipment can be cleaned by rinsing the inner wall of the upper cylinder 1 with a water gun.

[0044] The implementation principle of this utility model is as follows: This utility model discloses an air pollution control device, comprising a cylindrical body composed of an upper cylinder 1, a middle cylinder 2, and a lower cylinder 3. The upper cylinder 1 is equipped with a spiral separator 5 and a fan 4; the middle cylinder 2 is equipped with a cyclone separator 8 and a suction inlet 7; and the lower cylinder 3 is equipped with a flow stabilizer 9, a water storage chamber, and a secondary water tank 10. The secondary water tank 10 is divided into a water level monitoring tank 12 and a waste disposal tank 13, and a flow-guiding baffle is provided between the inlets of the water level monitoring tank 12 and the waste disposal tank 13 on the inner wall of the lower cylinder 3. This utility model, through its dual separation structure and flow-stabilizing design, effectively improves the air-water separation efficiency, prevents equipment blockage and shaking, separates waste collection and water level monitoring functions, facilitates maintenance and cleaning, and is suitable for various air purification applications containing dust, waste, and toxic gases.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
