Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically a pulse self-cleaning air filter. Background Technology

[0002] Pulse self-cleaning air filters have been widely used in the air purification field due to their advantages such as low air consumption, strong burst force, and good flushing effect. However, existing large-scale pulse self-cleaning air filters have multiple filter elements inside. When backflushing a filter element online, the dust on the filter element will be blown onto other adjacent filter elements, and the blown-off dust cannot be discharged in time, resulting in poor backflushing cleaning effect and poor filtration effect of the filter elements. Utility Model Content

[0003] The main purpose of this utility model is to provide a pulse self-cleaning air filter to solve the problem in the prior art where, when a pulse self-cleaning air filter performs online backflushing on a certain filter element, the dust on the filter element is blown onto other adjacent filter elements, and the blown-off dust cannot be discharged in time, resulting in poor backflushing cleaning effect.

[0004] To achieve the above objectives, this utility model provides a pulse self-cleaning air filter, comprising a filter chamber and a clean air chamber separated from each other. The filter chamber is provided with multiple filter elements, the interior of which is connected to the clean air chamber. The clean air chamber is provided with a backflush pipe for backflushing the filter elements, and the backflush pipe is provided with a backflush head. The filter chamber is provided with an openable and closable partition located between adjacent filter elements. The partition can divide the filter chamber into multiple compartments, and each compartment is connected to a main suction pipe through a dust collection branch pipe.

[0005] Furthermore, the back-blowing head is equipped with a back-blowing control valve, and the dust collection branch pipe is equipped with a dust collection control valve; the dust collection main pipe is connected to a dust collection fan, and the dust collection fan is connected to a dust collection bag.

[0006] Furthermore, the partition is a louvered design.

[0007] Furthermore, the partition includes a square window frame, the internal cavity of which is provided with multiple blades arranged from top to bottom, one end of a rotating arm is fixedly connected to the rear side of the blades, the other end of the rotating arm is hinged to a linkage rod, and the middle of the rotating arm is hinged to the window frame; an electric push rod for driving the linkage rod to move up and down is connected to the window frame.

[0008] Furthermore, one end of the electric push rod is hinged to the window frame, and the other end is hinged to the fixing rod, with the fixing rod and the linkage rod being fixedly connected.

[0009] Furthermore, the outer side of the electric linear actuator is fitted with a bellows.

[0010] Furthermore, an air inlet chamber is located below the filter chamber, and the air inlet chamber and the filter chamber are connected by a connecting port; a filter screen is located on the side of the air inlet chamber.

[0011] Furthermore, the clean air chamber is equipped with a clean air outlet.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a baffle, when backflushing a certain filter element, the baffle can be closed to isolate a separate chamber. This prevents dust from one filter element from being blown onto another, and other filter elements can be used normally during the backflushing process. After backflushing is complete, the baffle can be opened, and the backflushed filter elements can be used normally.

[0014] By setting up separate suction pipes, a main suction pipe, and a suction fan, dust blown into the compartment can be sucked out in a timely manner; the space inside the compartment is small, and the suction pipe can suck out the dust and clean it.

[0015] The pulse self-cleaning air filter of this invention has good backflushing and cleaning efficiency, and the filter element has a better filtration effect after backflushing and cleaning. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, according to an embodiment of the present invention, a pulse self-cleaning air filter is provided, including a filter chamber 1 and a clean air chamber 2 separated from each other. The filter chamber 1 is provided with a plurality of filter elements 3, and the interior of the filter elements 3 is connected to the clean air chamber 2. The clean air chamber 2 is provided with a backflush pipe 4 for backflushing the filter elements 3, and the backflush pipe 4 is provided with a backflush head 401. The filter chamber 1 is provided with an openable and closable partition 5 located between adjacent filter elements 3. The partition 5 can divide the filter chamber 1 into a plurality of compartments, and each compartment is connected to a main suction pipe 6 through a dust suction branch pipe 9.

[0023] The back-blowing head 401 is equipped with a back-blowing control valve, and the dust suction branch pipe 9 is equipped with a dust suction control valve; the dust suction main pipe 6 is connected to the dust suction fan 7, and the dust suction fan 7 is connected to the dust suction bag 8.
