Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to an air filter barrel structure of a filter. Background Art

[0002] The filter is used to mix or filter industrial medicines or liquids to obtain medicines or liquids without impurities, and is mostly used in the electroplating industry. The current filter mainly includes a frame, a filter barrel, a filter pump, a control box and a medicine adding barrel. In the prior art, there is a solution to blow the residual liquid medicine in the filter barrel to the medicine tank through an air intake device, which reduces the discharge of wastewater and is very environmentally friendly. However, the air intake device does not filter the air, which may cause contamination of the filter barrel or the medicine tank. Utility Model Content

[0003] In view of the deficiencies in the prior art, the main purpose of the utility model is to provide an air filter barrel structure of a filter machine which can filter and purify air and has a simple structure and is easy to maintain.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air filter barrel structure of a filter machine, comprising a cylindrical barrel body, a barrel cover and an air inlet and outlet structure are respectively provided at both ends of the cylindrical barrel body, the air inlet and outlet structure comprises an air inlet cover plate and an air outlet pipe extending into the cylindrical barrel body, a portion of the air outlet pipe located inside the cylindrical barrel body is provided with a plurality of air holes, a plurality of superimposed filter materials are provided in the cylindrical barrel body, and a plurality of air inlet holes connected to the cylindrical barrel body are provided on the air inlet cover plate.

[0005] Preferably, the air outlet pipe is provided with a connecting flange connected to the blower.

[0006] Preferably, the barrel cover is sealed and fixedly connected to the cylindrical barrel body by a plurality of locking bolts.

[0007] Preferably, a mounting plate is also connected to the cylindrical barrel body.

[0008] Compared with the prior art, the utility model has the following advantages: air is taken in through multiple air inlet holes on the air inlet cover at the bottom of the air filter barrel, and the air enters the air outlet pipe through the air holes after being filtered by the filter material, wherein the air outlet pipe is connected to the inlet of the blower, and then enters the medicine tank through the outlet of the blower. This scheme can fully filter the air, ensure the quality of the air entering the medicine tank, and has a simple structure. The filter material can be installed and replaced through the detachable barrel cover, which is convenient for maintenance. After installation, maintenance can be carried out directly from the top barrel cover without disassembling the entire air filter barrel. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 As shown, an air filter barrel structure of a filter comprises a cylindrical barrel body 1, a barrel cover 2 and an air inlet and outlet structure are respectively provided at both ends of the cylindrical barrel body 1, the air inlet and outlet structure comprises an air inlet cover plate 3 and an air outlet pipe 4 extending into the cylindrical barrel body 1, a portion of the air outlet pipe 4 located in the cylindrical barrel body 1 is provided with a plurality of air holes 5, a plurality of superimposed filter materials 6 are provided in the cylindrical barrel body 1, and a plurality of air inlet holes 7 connected to the cylindrical barrel body 1 are provided on the air inlet cover plate 3.

[0016] The air filter barrel structure of a filter machine of the present scheme takes in air through multiple air inlet holes 7 on the air inlet cover plate at the bottom of the air filter barrel. The air is filtered by the filter material 6 and then enters the air outlet pipe 4 through the air hole 5, wherein the air outlet pipe 4 is connected to the inlet of the blower, and then enters the medicine tank through the outlet of the blower. The present scheme can fully filter the air, ensure the quality of the air entering the medicine tank, and has a simple structure. The filter material 6 can be installed and replaced through the detachable barrel cover 2, which is convenient for maintenance. After installation, maintenance can be carried out directly from the top barrel cover 2 without disassembling the entire air filter barrel.

[0017] Preferably, a connecting flange 8 connected to the blower is provided on the air outlet pipe 4. The setting of the connecting flange 8 can ensure a stable and effective connection between the air filter barrel and the blower inlet.

[0018] Preferably, the barrel cover 2 is sealed and fixedly connected to the cylindrical barrel body 1 through a plurality of locking bolts 9. Such a configuration can facilitate the disassembly and assembly of the barrel cover 2 and is easy to maintain.

[0019] Preferably, a mounting plate 10 is also connected to the cylindrical barrel body 1. The arrangement of the mounting plate 10 can facilitate the mounting and fixing of the air filter barrel and the filter frame.
