It is easy to stick to the net for a long time during the separation of feed gas and material, and manual cleaning is required. Incomplete manual cleaning often causes blockage, which will cause problems such as respirator explosion, pipeline blockage, and cracking of the storage tank due to excessive pressure.

DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "fixed", "integrally formed", "left", "right" and similar expressions used in this specification are for illustrative purposes only. In the drawings, units with similar structures are marked with the same reference numerals.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by technicians in the technical field of the utility model. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the utility model.

[0025] like Figure 1-3As shown, an embodiment of the utility model is: a self-cleaning breathing device, provided with a filter assembly, an exhaust structure 7 and a separation assembly; one side of the upper part of the filter assembly is connected to the input end of the exhaust structure 7, and the upper part of the filter assembly is connected to the output end of the separation assembly on the other side; the filter assembly includes a dust cover 1, a filter element structure 8 and a dust collection cylinder 2; the filter element structure 8 is installed on the mounting position inside the dust collection cylinder 2; the bottom of the dust cover 1 is fixed to the top of the dust collection cylinder 2 by a stirrup 10; the separation assembly is provided with a diaphragm valve 3, a back-blowing air tank 4, an air filter pressure reducing valve 5 and a gas pipeline 9; the input end of the air filter pressure reducing valve 5 is fixed to the output end of the gas source, the air inlet end of the air filter pressure reducing valve 5 is fixed to the inlet of the back-blowing air tank 4, the outlet of the back-blowing air tank 4 is fixed to the air inlet of the diaphragm valve 3, the air outlet of the diaphragm valve 3 is connected to one end of the gas pipeline 9, and the other end of the gas pipeline 9 extends to the inside of the dust cover 1.

[0026] A separation hole is provided on one side of the dust removal cover 1 , and an exhaust hole is provided on the other side of the dust removal cover 1 . The exhaust hole is connected to one end of the transfer tube 6 , and the other end of the transfer tube 6 is connected to the exhaust structure 7 .

[0027] The filter element structure 8 includes a filter element plate and a filter element barrel; the filter element plate is fixed at a specified position inside the dust removal barrel 2; the upper end of the filter element barrel passes through the filter element plate and extends to the inside of the dust removal cover 1; the bottom of the filter element barrel extends to the lower part of the dust removal barrel 2.

[0028] The gas transmission pipeline 9 is provided with a main pipeline 91 and an auxiliary pipeline 92; the main pipeline 91 and the auxiliary pipeline 92 are vertically arranged; one end of the main pipeline 91 passes through the separation hole and is fixedly connected with the air outlet of the diaphragm valve 3; the other end of the main pipeline 91 extends into the exhaust hole; a connecting hole is provided on the lower surface of the middle area of ​​the main pipeline 91, and one end of the auxiliary pipeline 92 is fixedly connected with the connecting hole; the other end of the auxiliary pipeline 92 extends to the interior of the filter cartridge.

[0029] The exhaust structure 7 is a movable pneumatic butterfly valve, and the transfer tube 6 is fixedly connected to the inlet of the pneumatic butterfly valve.

[0030] It should be noted that: when the powder transmission device transfers the powder and gas into the dust collection cylinder 2 together (the powder transmission device transfers the gas and powder into the dust collection cylinder 2 by its own pressure), part of the dust will fall into the filter cartridge, and the remaining dust will pass through the dust collection cylinder 2 and the dust cover 1 and fall into the bottom of the dust collection cylinder 2 again, and then enter the pipeline of the powder transmission device for subsequent processing;

[0031] When the internal air pressure of the powder conveying device is greater than a preset value, the exhaust structure 7 (pneumatic butterfly valve) opens to reduce the air pressure in the pipeline. When the set air pressure is reached, the pneumatic butterfly valve closes.

[0032] When it is necessary to clean the dust in the filter cartridge:

[0033] When the gas source (air pump) works and passes the gas through the diaphragm valve 3, the air filter pressure reducing valve 5 and the gas transmission pipeline 9 into the filter cartridge and the dust removal cover 1 in sequence, the gas blows the dust in the filter cartridge through the auxiliary pipeline 92, so that the dust is separated from the filter cartridge and falls into the interior of the powder transmission device; at the same time, the gas blows the inside of the dust removal cover 1 through the main pipeline 91, so that the dust is separated from the inside of the dust cover and falls into the interior of the powder transmission device.

[0034] Embodiment 2: The inner walls of the dust removal cover 1, the dust removal cylinder 2 and the gas transmission pipeline 9 are sprayed with carbon Teflon coating.

[0035] It should be noted that spraying carbon Teflon coating on the inside of the dust cover 1, the dust cylinder 2 and the gas pipeline 9 can effectively reduce the adhesion of powder on the surface, thereby increasing the service life of the equipment and reducing the workload of dust removal.

[0036] Embodiment 3: A plurality of air injection holes 93 are provided on the outer wall of the auxiliary pipe 92 , and the plurality of air injection holes 93 are distributed on the outer wall of the auxiliary pipe 92 in a spiral shape.

[0037] It should be noted that: a plurality of jet holes 93 are formed on the outer wall of the auxiliary pipe 92, which improves the dust removal efficiency. The jet holes 93 are spiral-shaped, which reduces the mutual cancellation of gases from each jet hole 93 and further improves the dust removal efficiency.

[0038] It should be noted that the above-mentioned technical features are further combined with each other to form various embodiments not listed above, which are all deemed to be within the scope of the present utility model specification; and, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should fall within the scope of protection of the claims attached to the present utility model.
