Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments as follows:

a filtering and dust removing device with a quick replacement function is shown in figures 1 to 3 and comprises a frame 1, a box shell 2, a sealing strip 3, a coarse filter screen 4, a semi-fine filter screen 5, a fine filter screen 6 and at least three blocking safety valves 7.

The box shell 2 is arranged at the rear end of the frame 1, and the backpack type box shell is arranged at the rear end of the frame (1), so that the operation is convenient, and the humanized design is realized. The box shell 2 is provided with an air inlet 21 and an air outlet 22, wherein the air inlet 21 is arranged at the top end of the box shell 2, and the air outlet 22 is arranged at the bottom end of the box shell 2. The wind from the wind inlet 21 is exhausted to the atmosphere from the wind outlet 22, namely, the box shell 2 is an upper air inlet and lower air exhaust structure.

Sealing strip 3 sets up in case shell 2, and sealing strip 3 divides into the filter chamber 24 and the play chamber 25 of intercommunication with case shell 2, and air intake 21 sets up in filter chamber 24, and air outlet 22 sets up on going out chamber 25, and wind flows to play chamber 25 by filter chamber 24. The coarse filter 4, the semi-fine filter 5 and the fine filter 6 are movably arranged in the filter cavity 24 in sequence to form multi-stage filtering operation, so that the filtering effect is improved. Here, coarse strainer 4, half fine filter screen 5 and fine filter screen 6 adopt movable mounting's mode, like coarse strainer 4, half fine filter screen 5 and fine filter screen 6 adopt the slide to assemble on case shell 2, and at this moment, the outside activity of case shell 2 sets up chamber door 23, and is easy to assemble, and its advantage is that can tear open fast and trade or directly open chamber door 23 and wash, saves the time of washing greatly. In addition, the sealing strips 3 are arranged on the inner side wall of the box shell 2, so that the sealing performance of the box shell 2 is improved.

Another important point of the application is that the blocking safety valves 7 are arranged on the bottom plate of the filter cavity 24, the blocking safety valves 7 are communicated with the filter cavity 24 and the outlet cavity 25, one of the blocking safety valves 7 is communicated with the cavity corresponding to the coarse filter 4 and the air inlet 21, one of the blocking safety valves 7 is communicated with the cavity corresponding to the coarse filter 4 and the semi-fine filter 5, and one of the blocking safety valves 7 is communicated with the cavity corresponding to the fine filter 6 and the semi-fine filter 5. The blockage safety valve 7 is used for protecting the filter screen and avoiding the filter screen from being deformed by air pressure impact after being blocked.

Regarding the structure of the block safety valve 7, it includes a cover plate and a torsion spring, the cover plate is arranged on the bottom plate of the filter chamber 24 through the torsion spring, when the air pressure is too high, the cover plate will be opened, so that the air flow enters the outlet chamber 25 directly from the filter chamber 24.

In order to increase the service life, the material of the cabinet 2 is stainless steel. The coarse filter 4, the semi-fine filter 5 and the fine filter 6 are also made of stainless steel.

A one-way air channel is formed in the box shell 2 through the sealing strips 3, air entering from the air inlet 21 must sequentially pass through the coarse filter 4, the semi-fine filter 5 and the fine filter 6, then the air is discharged into the air from the air outlet 22, and the filter screens with different filtering precisions can be quickly disassembled or replaced according to different filtering requirements. Design on the sealing strip 3 and blockked up relief valve 7, too big when the filter screen windage, blockked up relief valve 7 and open the pressure release, the filter screen that the protection corresponds improves life.

The invention has been described above with reference to a preferred embodiment, but the scope of protection of the invention is not limited thereto, and various modifications can be made and equivalents can be substituted for elements thereof without departing from the scope of the invention, and features mentioned in the various embodiments can be combined in any way as long as there is no structural conflict, and any reference sign in the claims should not be construed as limiting the claim concerned, and the embodiments should be regarded as being exemplary and non-limiting in any way whatsoever. Therefore, all technical solutions that fall within the scope of the claims are within the scope of the present invention.
