Description

Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically to a multi-channel air filtration device. Background Technology

[0002] Aeration is a crucial step in wastewater treatment. By forcibly introducing air into the wastewater, it increases the dissolved oxygen content, mixes and stirs the wastewater, prevents suspended solids from settling, and removes harmful gases from the wastewater, thus purifying the water using physical and biochemical principles.

[0003] Untreated air contains dust, particulate matter, impurities, and even insects. If these impurities enter the aeration network and aerators (especially microporous aerators) directly with the air, they will accumulate and cause blockages over time. Aerator blockages lead to uneven aeration, oxygen deficiency in some areas, and reduced treatment efficiency. To maintain oxygen supply, it is necessary to increase the blower's airflow and pressure, which significantly increases energy consumption and operating costs. In severe cases, it may even require shutdown for maintenance and aerator replacement, increasing maintenance costs and downtime losses. Therefore, the air used for aeration must be filtered.

[0004] Existing aeration equipment (Roots blowers, high-pressure blowers, rotary blowers, air pumps, etc.) mostly have simple filter devices installed at their air inlets, which can prevent airborne particles and dust from entering the blower. However, for areas where sandstorms frequently occur, the existing simple protective filter devices are obviously not suitable. Sand and dust will quickly clog the air inlet, causing the equipment to malfunction. Therefore, we propose a multi-channel air filtration device. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-channel air filtration device includes a static pressure box, with multiple air outlets fixedly installed on the front wall of the static pressure box, a pressure transmitter connected to the side wall of the static pressure box via connecting pipes, multiple ventilation pipes fixedly installed on the top of the static pressure box, a first connecting ring connected to the top flange of the ventilation pipes, a second connecting ring detachably and sealed on the first connecting ring, and a filter cartridge fixedly installed on the top of the second connecting ring.

[0008] As a further embodiment of this utility model: a vertical tube is fixedly provided on the inner wall of the first connecting ring, and multiple locking blocks are fixedly installed on the outer peripheral wall of the vertical tube. The second connecting ring is sleeved on the vertical tube, and multiple protrusions are fixedly installed on the inner wall of the second connecting ring, with the protrusions located below the locking blocks.

[0009] As a further embodiment of this utility model: a sealing ring is fixedly provided at the bottom of the second connecting ring, and the bottom surface of the sealing ring is in close contact with the top surface of the first connecting ring.

[0010] As a further embodiment of this utility model, the top inner wall of the static pressure box is fixedly provided with reinforcing ribs.

[0011] As a further embodiment of this utility model: the top flange of the static pressure box is connected to a cover, and the outer wall of the cover is provided with multiple through holes.

[0012] As a further improvement of this utility model: the outer wall of the air outlet is fitted with a plug by an external thread, and a sealing gasket is provided inside the plug.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the design of the filter cartridge, can effectively filter the air entering the static pressure chamber, thereby greatly reducing the amount of dust and impurities entering the aeration equipment. By using a filter cartridge with a large filtration area, the maintenance cycle of the filter cartridge can be extended. With the addition of a pressure transmitter, the air pressure inside the static pressure chamber can be monitored. When a large amount of dust and impurities adhere to the filter cartridge, causing the air pressure inside the static pressure chamber to drop to the set value during the operation of the aeration equipment, an alarm can be triggered through the associated equipment, thus reminding the staff to clean the filter cartridge, making it more convenient to use.

The filter cartridge 13 effectively filters the air entering the static pressure chamber 1, significantly reducing dust and impurities entering the aeration equipment. The use of a large-area filter cartridge 13 extends its maintenance cycle. The pressure transmitter monitors the air pressure within the static pressure chamber 1.
