[0002] Food processing refers to the grain grinding, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, as well as processing activities of vegetables, fruits, nuts and other foods that directly use agricultural, forestry, animal husbandry and fishery products as raw materials. With the development of modern industry, the requirements for food processing equipment are constantly increasing.

[0003] Feed mills generate a lot of dust in the daily production process, which can easily cause dust explosion safety accidents. Manufacturers usually configure dust removal devices for different floors and locations where dust removal is required to carry out dust removal operations. Cyclone dust collectors are usually used to sort and recycle some light particle powders and impurities to reduce pollution to the environment. Cyclone dust collectors are a type of dust removal device. The dust removal mechanism is to make the dust-laden airflow rotate, separate the dust particles from the airflow and capture them on the wall with the help of centrifugal force, and then use gravity to make the dust particles fall into the ash hopper. It is generally composed of an air inlet pipe, an exhaust pipe, a cylinder, a cone and an ash hopper.

[0004] During operation, the structure of the cyclone dust collector is used to enable the airflow at the air inlet to move upward and eventually flow out from the outlet position, thereby achieving the purpose of dust removal. However, this cyclone dust collector cannot effectively remove fine dust particles, and the dust removal effect is not ideal. In addition, the above-mentioned cyclone dust collector cannot classify the trapped dust, thereby limiting the scope of use of the cyclone dust collector. Utility Model Content

In the actual working process, the dust removal bag 16 is regularly cleaned and replaced.

[0021] like Figure 1 As shown, in order to reprocess the gas and dust flowing downward after the cyclone dust removal, a lower treatment cylinder 5 is installed at the outlet of the cyclone cylinder 11, and the outer wall of the lower treatment cylinder 5 is installed on the mounting frame 10 through an angle piece. A filter cylinder 4 is installed at the center of the lower treatment cylinder 5, and a conical material distribution hopper 7 is installed on the upper part of the inner cavity of the filter cylinder 4. A reflux outlet 17 is connected to the outer peripheral wall of the lower treatment cylinder 5, and the reflux outlet 17 is connected to the treatment box air inlet 12 through a gas pipeline and an air pump.

[0022] This embodiment also includes a cleaning device installed in the lower treatment cylinder 5 for cleaning the filter cylinder 4; Figure 1 As shown, the above-mentioned cleaning device includes a rotating transmission assembly 8 which is arranged on the upper part of the lower processing cylinder 5 and passes through the top of the lower processing cylinder 5, and a cleaning brush 6 is installed on the bottom surface of the rotating transmission assembly 8, which is used to clean the filter cylinder 4 to avoid clogging; in this embodiment, the above-mentioned cleaning brushes 6 are at least provided in two groups, and at least two groups of cleaning brushes 6 are evenly distributed in the circumferential direction; each cleaning brush 6 adopts a double-sided brush, which is in frictional contact with the filter cylinder 4 and the lower processing cylinder 5 respectively, and is used to clean the filter cylinder 4 and the lower processing cylinder 5 at the same time.

[0023] In this embodiment, the above-mentioned filter cartridge 4 includes an upper mounting portion and a lower filter portion connected by a flange, the upper mounting portion is rotatably connected to the rotating transmission assembly 8, and a plurality of filter holes are opened on the outer peripheral wall of the lower filter portion; the conical distribution hopper 7 is installed in the upper part of the inner cavity of the lower filter portion.

[0024] See also Figure 3The above-mentioned rotating transmission assembly 8 includes a crown gear 8-3 arranged between the filter cylinder 4 and the lower processing cylinder 5, the crown gear 8-3 is rotatably connected to the upper part of the filter cylinder 4 through a rolling bearing, and the cleaning brush 6 is installed on the bottom surface of the crown gear 8-3; it also includes a driving shaft 8-1 rotatably connected to the lower processing cylinder 5 through a seat bearing, the driving shaft 8-1 is arranged horizontally, and also includes an active gear 8-2 key-connected to the driving shaft 8-1, and the active gear 8-2 penetrates the notch opened on the top surface of the lower processing cylinder 5 and meshes with the crown gear 8-3.

[0025] The cleaning device also includes a rotating drive assembly 9 installed on the mounting frame 10 and connected to the rotating transmission assembly 8, which is used to drive the cleaning brush 6 to rotate around the filter cartridge 4 to perform a cleaning operation; wherein the above-mentioned rotating drive assembly 9 includes a reduction motor installed on the mounting frame 10, a driving sprocket is keyed to the output shaft of the reduction motor, and also includes a driven sprocket keyed to the driving shaft 8-1, and a transmission chain is installed between the driving sprocket and the driven sprocket.

[0029] Working principle:

[0030] Under the action of the induced draft fan, the gas enters the cyclone barrel 11 from the cyclone inlet 14, and a vortex is generated in the cyclone barrel 11, so that most of the dust with relatively light mass flows into the upper treatment box 15 from the cyclone outlet 13 installed in the middle of the top of the cyclone barrel 11, and the light dust flowing into the upper treatment box 15 is captured by the dust bag 16 installed on the upper treatment box 15; under the action of the airflow, the relatively heavy dust and the remaining small part of the relatively light dust enter the lower treatment barrel 5 from the lower end outlet of the cyclone barrel 11, and under the action of the conical distribution hopper 7, the airflow flows to the peripheral wall of the filter barrel 4, thereby realizing the filtering operation; in the filtering process, the large-particle dust with relatively large mass is intercepted and falls downward into the dust collecting barrel 1, and the small-particle dust filtered by the filter barrel 4 flows into the upper treatment box 15 from the reflux outlet 17, the gas pipeline and the treatment box air inlet 12, and then is captured by the dust bag 16 installed on the upper treatment box 15;
