Description

Technical Field

[0001] The utility model relates to the technical field of belt cleaning devices, in particular to a compressed air dust cleaning and suppressing device for a belt conveyor. Background Art

[0002] In industry, the use of belts to transport materials has been widely applied. The working reliability and efficiency of the belt directly affect the benefits during use. Keeping the working surface of the belt clean is crucial for working benefits, extending the belt life, and maintaining environmental cleanliness. Currently, most belt conveyors use belt cleaning devices installed at the head to remove the remaining materials on the working surface of the belt. The belt cleaning device mainly relies on the scraper on it to clean the remaining materials. When the belt is running, the materials adhered to the belt are swept off by the scraper. The long-term contact causes great wear to both the belt and the scraper.

[0003] In the existing belt cleaning devices, there are also those that use compressed air to blow the belt to blow off a large amount of adhesives and then use a scraper to scrape off the remaining materials. When this structure is in use, since it is only a single-hole linear air outlet structure, the coverage effect on the belt is not good, there are large areas on the belt surface that cannot be blown, and the dust suppression effect is not good.

[0004] Therefore, a compressed air dust cleaning and suppressing device for a belt conveyor is provided to solve the above problems. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that in the existing belt cleaning devices, there are also those that use compressed air to blow the belt to blow off a large amount of adhesives and then use a scraper to scrape off the remaining materials. When this structure is in use, since it is only a single-hole linear air outlet structure, the coverage effect on the belt is not good, there are large areas on the belt surface that cannot be blown, and the dust suppression effect is not good. Therefore, a compressed air dust cleaning and suppressing device for a belt conveyor is provided. The compressed air dust cleaning and suppressing device for a belt conveyor includes:

[0006] A head pulley and a belt, the belt is sleeved on the head pulley. It is characterized in that it further includes an installation mechanism, a jetting mechanism, and an air intake mechanism. The two installation mechanisms are respectively arranged on both sides of the head pulley. The jetting mechanism is fixedly installed between the installation mechanisms. The air intake mechanism is communicated with the jetting mechanism. The jetting mechanism moves up and down along the installation mechanism.

[0007] The jetting mechanism includes a jetting pipe. A plurality of flat nozzles are opened on the jetting pipe. The flat nozzles are arranged in a straight line. One end of the jetting pipe is communicated with the air intake mechanism. The other end of the jetting pipe is provided with an end cover.

[0008] Further, the installation mechanism includes a U-shaped mounting bracket, a positioning ring and a locking bolt. The locking bolt is arranged at the upper end of the U-shaped mounting bracket. The positioning ring is arranged inside the U-shaped mounting bracket and can move up and down along the U-shaped mounting bracket. The positioning ring is sleeved on both ends of the jet pipe.

[0009] Further, a first positioning hole is formed in the positioning ring, and second positioning holes are symmetrically formed on both sides of the U-shaped mounting bracket. The first positioning hole and the second positioning holes are fixed by positioning bolts.

[0010] Further, the number of the first positioning holes is two, and the first positioning holes are arranged on the side of the positioning ring close to the U-shaped mounting bracket.

[0011] Further, there are multiple second positioning holes on each side of the U-shaped mounting bracket.

[0012] Further, the air inlet mechanism includes a hose and an air inlet pipe. One end of the hose is communicated with the jet pipe, and the other end of the hose is communicated with the air inlet pipe.

[0013] Further, the end of the air inlet pipe far from the hose is communicated with an external air source.

[0014] Further, an electric butterfly valve and a regulating ball valve are sequentially arranged on the air inlet pipe from the end communicated with the external air source to the end communicated with the hose.

[0015] Implementing the present utility model has the following beneficial effects:

[0016] 1. Through the arranged jet pipe structure of the present utility model, compressed air will enter the jet pipe from the air inlet pipe through the hose and finally be sprayed out at high speed and high pressure through multiple groups of flat nozzles to blow the dust on the surface of the return belt under the head pulley; and because the flat nozzles are of a flat structure, the sprayed gas forms a fan surface, and the fan surfaces of the sprayed gas are connected to each other, which can comprehensively cover the outer side wall of the belt and blow off the adhered dust; it can improve the coverage effect on the belt, greatly reduce the belt adhesives, improve the scraper life and the cleaning rate of the adhesives, reduce the wear of each rotating drum and idler of the belt conveyor caused by dust, and improve the service life of mechanical equipment; to a large extent, it inhibits the dust dispersion on site and greatly improves the on-site working environment.
