Abstract
The utility model relates to an air purification device. An air filter is characterized by comprising a barrel-shaped cylinder body and connecting plates covering two ends of the cylinder body, wherein flange plates are respectively arranged at two ends of the cylinder body, the connecting plates and the flange plates are correspondingly connected by bolts, sealing gaskets are sandwiched between the flange plates and the connecting plates, each connecting plate is provided with a connector identical with the connector of the inner cavity of the cylinder body, the cylinder body is internally provided with a positioning sleeve and at least one filter plate, the shape of the positioning sleeve is matched with that of the cylinder body, the peripheral edge of the filter plate is connected with the peripheral wall of the positioning sleeve in an embedded manner, and filter holes are arranged on the filter plate. Aiming at the shortages of the existing products, the air filter has the advantages of longer service life, simple structure and low manufacturing cost and is convenient to use and maintain.
Description
Technical field
The utility model relates to a kind of air cleaning unit.
Background technology
In commercial production and scientific experimentation field, many equipment use air to drive pneumatic mechanism as power or working media air through slit and realize motions such as displacement, vibration.Because the physical dimension of slit is very little, in case airborne molecule gets into wherein, will wear and tear or stop up slit, change the dynamics and the kinematics condition of mechanism, influence the operate as normal of mechanism, so air cleaning unit need be set.In the middle of the existing air filter technology, in the majority with the form that poromerics filters, because poromerics in use can be stopped up filter efficiency by dust and decrease; So need often to change; Not only make troubles to use, and consumption is more relatively, use cost is high.
Summary of the invention
The utility model has than the long life to the deficiency of existing product, and is simple in structure, low cost of manufacture, and operation and maintenance is air filter easily.
The utility model is realized through following technical scheme:
Air filter; It is characterized in that: the cylinder body and the connecting plate that is covered in these cylinder body two ends that comprise a tubular; The two ends of this cylinder body are respectively arranged with ring flange, and each connecting plate is corresponding with ring flange to be connected through bolt, is folded with sealing gasket between ring flange and the connecting plate; Each connecting plate is provided with the connector identical with inner chamber of cylinder block; Be provided with abutment sleeve and at least one filter that a shape matches in this cylinder body, the periphery of this filter is embedded to be connected on the perisporium of abutment sleeve, and filter is provided with filtering holes.
Described filter has three, and air flow is pressed from large to small in the aperture on each filter.
The utlity model has following advantage: the utility model simple in structure, in light weight, cost is low, firm anticorrosion, can bear higher pressure, be convenient to the cleaning, advantages such as long service life.
Description of drawings
Fig. 1 is the cutaway view of the agent structure of the utility model,
1 is abutment sleeve among the figure, and 2 is cylinder body, and 31,32 is connecting plate, and 21 is flange, and 41,42 is connector, and 5 is filter.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Air filter as shown in Figure 1; Comprise the cylinder body 2 and the connecting plate 31,32 that is covered in these cylinder body 2 two ends of a tubular, the two ends of this cylinder body 2 are respectively arranged with ring flange 21, and each connecting plate 31,32 is corresponding to the bolt connection with ring flange 21; Ring flange 21 and connecting plate 31, be folded with sealing gasket 8 between 32; Each connecting plate 31,32 is provided with the connector 41,42 identical with cylinder body 2 inner chambers, is provided with abutment sleeve 1 and three filters 5 that a shape matches in this cylinder body 2, and the periphery of this filter 5 is embedded to be connected on the perisporium of abutment sleeve 1; Filter is provided with filtering holes, and air flow is pressed from large to small in the aperture on each filter.
The utlity model has following advantage: the utility model simple in structure, in light weight, cost is low, firm anticorrosion, can bear higher pressure, be convenient to the cleaning, advantages such as long service life.
