DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0040] Example 1:

[0041] In this embodiment, if Figure 1-3 As shown, an industrial air filter proposed by the utility model includes a shell 1, and also includes a primary filter unit, a filter unit, an output pipe 4, a support unit and a collection unit. The primary filter unit is arranged on the top of the shell, and the primary filter unit is used to preliminarily filter the dust and impurities entering the air; the filter unit is arranged inside the shell, and the filter unit is used to further filter the dust and impurities entering the air; the output pipe is arranged on the back of the shell, and the output pipe is used to output the filtered air; the support units are arranged at the four corners of the bottom of the shell, and the support units play a bearing and fixing role; the collection unit is arranged at the bottom of the shell, and the collection unit is used to collect dust and impurities.

[0042] In the present embodiment, it is further configured that the primary filter unit includes an air inlet duct 21 and a filter screen plate 22, the air inlet duct is connected to the top of the shell, and the air inlet of the air inlet duct is vertically downward; the filter screen plate is connected to the air inlet of the air inlet duct.

[0043] In this example, since the air inlet is facing vertically downward, some larger garbage and impurities can be prevented from entering the air inlet or clogging the filter plate. The mesh shape of the filter plate is honeycomb or square. The filter plate is set with a smaller aperture to prevent some impurities and dust from being sucked in. The filter plate can be disassembled, cleaned and replaced.

[0044] In this embodiment, it is further configured that the filter unit includes a filter cartridge frame 31, a filter cartridge 32 and a pulse assembly 33, and the filter cartridge frame array is arranged inside the shell; the filter cartridge is installed on the filter cartridge frame, and the filter cartridge can be a single filter cartridge or a double filter cartridge according to the size of the filter cartridge and the size of the filter cartridge frame; one end of the pulse assembly is arranged on the back of the shell, and the other end of the pulse assembly faces the filter cartridge.

[0045] In this example, when the dust on the surface of the filter cartridge is thick, the pulse component activates the spray valve to blow the dust off the outer surface of the filter cartridge, and finally discharges it into the ash barrel through the ash hopper, which can greatly improve the use efficiency and service life of the filter cartridge. This control technology can use pressure difference or time control. This technology is existing technology and will not be elaborated here.

[0046] In this embodiment, one end of the output pipe is connected to the back of the shell, and the other end of the output pipe is connected to the driving device 5. The driving device can be an induced draft fan for controlling the flow direction of the gas.

[0047] In this embodiment, it is further configured that the supporting unit includes a structural leg 61, a base plate 62 and a connecting cross bar 63, the structural leg is vertically arranged, the top of the structural leg is connected to the four corners of the bottom of the shell; the surface of the base plate is connected to the bottom of the structural leg; the two ends of the connecting cross bar are respectively connected to adjacent structural legs.

[0048] In this example, the structural legs have a certain height, which enables the shell and the ash hopper to be suspended in the air and cooperate with the ash cylinder to collect dust.

[0049] In this embodiment, an ash hopper 11 is further arranged at the bottom of the shell, and an ash valve 12 is arranged in the ash hopper. The ash valve is opened at regular intervals, and a collection unit is used to remove dust to avoid affecting the gas quality.

[0050] In this embodiment, it is further configured that the collection unit includes an ash bucket 71 and a collection hose 72, the ash bucket is located below the ash hopper, and the ash bucket mouth corresponds to the ash hopper bottom; the upper end of the collection hose is connected to the ash hopper bottom, and the lower end of the collection hose is connected to the ash bucket mouth.

[0051] In this embodiment, a barometer 9 is further arranged on the back of the shell.

[0052] Example 2:

[0053] In this embodiment, if Figure 1-3 As shown, a plurality of openings are provided on the front side of the shell, and filter cartridge covers 8 are provided at the openings. The filter cartridge covers are used to seal the filter cartridge on one hand, and on the other hand, the filter cartridge covers can be pulled by pulling the filter cartridge cover surface to replace the filter cartridge.

[0054] In the present embodiment, a maintenance opening may be provided on the side of the shell. When a fault occurs inside the shell and maintenance cannot be performed by opening the filter cartridge cover, the inside of the shell may be inspected through the maintenance opening.

[0055] Example 3:

[0056] In this embodiment, if Figure 1-3 As shown, the shell is made of a whole steel plate, and the shell surface is coated with an oil-resistant coating, which can ensure that the shell has strong corrosion resistance and a long service life.

[0057] In the present embodiment, it is further configured that the filter cartridge frame adopts a cross steel frame structure, which has a strong load-bearing capacity and can effectively prevent the filter cartridge frame from deforming and affecting the gas quality.

[0058] In the present embodiment, it is further configured that the filter unit and the matching filter cartridge cover plate adopt a drawer-type structure to facilitate installation and inspection and maintenance.

[0059] The working principle of this industrial air filter is that the external dust-containing gas enters the shell through the filter screen and the air inlet duct, enters the exhaust chamber through the filter cartridge, and then inputs the filtered gas into the air compressor through the output pipe. Since the air contains dust impurities during the filtration process, larger particles are intercepted by the filter screen and smaller particles are attached to the surface of the filter cartridge. Therefore, at intervals or under the pressure difference setting, the pulse component is used to start the spray valve to blow off the dust on the outer surface of the filter cartridge and discharge it from the ash hopper to the ash barrel at intervals.
