Description

Technical Field

[0001] The utility model relates to the technical field of air filters, and more specifically to a glass fiber cotton type air filter. Background Art

[0002] The glass fiber cotton air filter is mainly installed at the interface position of the pneumatic diaphragm pump driving air source (generally compressed air). It is mainly used to filter the pneumatic diaphragm pump driving air source. It can effectively filter impurities such as rust, suspended particles, corrosive droplets, etc. carried in the compressed air, so as to clean the driving air source and prevent the premature wear of the pneumatic diaphragm pump air distribution valve slideway, thereby extending the maintenance cycle and service life of the air distribution valve, reducing the maintenance cost of the pneumatic diaphragm pump air distribution valve, and achieving cost reduction and efficiency improvement.

[0003] Existing glass fiber filters mainly rely on glass fiber wool to filter the air. During use, the glass fiber wool and the inside of the filter need to be cleaned regularly. Since traditional glass fiber filters are generally cylindrical in design, the glass fiber wool is generally loaded and unloaded on the upper side of the filter, and the top cover on the upper side of the filter is generally installed and fixed to the filter with a flange, and the flange and the filter are generally connected with multiple sets of bolts. As a result, when the top cover is disassembled, multiple sets of bolts need to be disassembled, which is time-consuming and labor-intensive, and reduces the convenience of cleaning the glass fiber wool.

[0004] In view of this, we propose a glass fiber cotton type air filter. Utility Model Content

[0029] A glass fiber cotton type air filter comprises a mounting cylinder 1, a top cover 8 is movably provided on the upper side of the mounting cylinder 1, a movable block 10 is movably provided on the inner side of the top cover 8, and a fixed block 11 is fixedly provided on the inner side of the top cover 8 at the lower side of the movable block 10, a plurality of groups of connecting blocks 12 are rotatably provided on the outer side of the movable block 10, a connecting block 2 121 is rotatably provided on the outer side of the plurality of connecting blocks 12, a mounting plate 13 is fixedly provided on the outer side of the connecting block 2 121, the mounting plate 13 movably passes through the top cover 8 and extends to the outer side, and a mounting block 14 is fixedly provided on the outer side of the mounting plate 13 at the outer side of the top cover 8, a clamping block 15 is fixedly provided on the inner side of the mounting block 14, a fixing disk 16 is fixedly provided on the outer side of the mounting cylinder 1, and the outer side of the fixing disk 16 is opened. A plurality of groups of slots 21 for docking card blocks 15 are provided, and a plurality of groups of limit springs 17 are provided on the inner side of the top cover 8. One ends of the plurality of limit springs 17 are respectively connected to the outer sides of the fixed blocks 11, and the other ends of the limit springs 17 are connected to the second connecting block 121. The limit springs 17 are not deformed in the initial state. When the movable block 10 moves to drive the connecting block 12 and the second connecting block 121 to move, the second connecting block 121 stretches the limit spring 17. At this time, the limit spring 17 is deformed. When the movable block 10 is not moved, the elastic potential energy of the limit spring 17 is released, thereby driving the second connecting block 121 to move and reset, thereby facilitating driving the card block 15 to be falsely inserted into the slot 21, thereby improving the installation convenience and installation stability of the top cover 8.

[0030] Specifically, an outer protective net 2 is movably inserted into the inner side of the installation cylinder 1, an inner lining net 3 is fixedly arranged on the inner side of the outer protective net 2, and glass fiber wool 4 is movably inserted between the inner lining net 3 and the outer protective net 2. The outer protective net 2 and the inner lining net 3 can limit the glass fiber wool 4, thereby improving the filtering effect of the glass fiber wool 4, and also facilitate the subsequent loading and unloading of the glass fiber wool 4.

[0031] Furthermore, a mounting groove 5 for docking with the outer protective net 2 is provided on the inner side of the mounting tube 1 . The mounting groove 5 can facilitate loading and unloading of the outer protective net 2 and cleaning of the outer protective net 2 .

[0032] It is worth noting that an air inlet pipe 6 is provided on one side of the mounting tube 1, and an air outlet pipe 7 is provided on the other side of the mounting tube 1. The gas enters through the air inlet pipe 6 and is finally discharged through the air outlet pipe 7, thereby improving the filtering efficiency of the gas.

[0033] It is worth noting that a sealing plate 9 is fixedly provided on the lower side of the top cover 8. The sealing plate 9 can be provided to facilitate sealing of the mounting cylinder 1, thereby ensuring the filtering effect of the device.

[0034] In addition, multiple groups of limit blocks 18 are fixedly arranged on the inner side of the top cover 8, and the multiple groups of limit blocks 18 are respectively movable and penetrate the multiple groups of connecting blocks 121. The limit blocks 18 can limit the connecting blocks 121, so that when the connecting blocks 121 move, they are displaced along the limit blocks 18, thereby ensuring the movement stability of the connecting blocks 121.

[0035] It must be mentioned that a connecting rod 19 is fixedly provided on the upper side of the movable block 10, the connecting rod 19 movably passes through the top cover 8 and extends to the upper side, and a handle 20 is fixedly provided on the upper end of the connecting rod 19 located on the upper part of the top cover 8. By pressing the handle 20, the connecting rod 19 and the movable block 10 can be easily driven to move, thereby improving the convenience of operation.

[0036] Working principle: First, the gas enters the inner side of the mounting tube 1 through the air inlet pipe 6, and after being filtered by the glass fiber wool 4, the gas is discharged through the air outlet pipe 7. When the glass fiber wool 4 needs to be replaced, first grasp the handle 20 and press it downward. The handle 20 drives the connecting rod 19 and the movable block 10 to move. When the movable rod 10 moves, it drives multiple groups of connecting blocks 12 to move. When the connecting block 12 moves, it drives the connecting block 2 121 to move. When the connecting block 2 121 moves, it drives the mounting plate 13 and the mounting block 14 to move. When the mounting block 14 moves, it drives the card block 15 to move. When the card block 15 moves, it is moved out of the card slot 21 on the inner side of the fixed disk 16. Then the top cover 8 can be removed from the fixed disk 16, and then the glass fiber wool 4 can be pulled out from between the outer protective net 2 and the inner lining net 3, so as to facilitate the cleaning or replacement of the glass fiber wool 4.
