Crushing device for producing moulded coal

Abstract

The invention provides a crushing device for producing moulded coal. The crushing device comprises a crushing mechanism, a vibration mechanism and a coarse material recycling mechanism. The crushing mechanism comprises a crushing machine body, a crushing motor and a scraper motor. The lower end of the crushing mechanism is provided with the vibration mechanism which is a vibration screen. The interior of the vibration screen is provided with screen cloth with the particle size being 3 mm, the upper portion of the vibration screen is provided with a coarse material outlet, and the lower portion of the vibration screen is provided with a discharge outlet. The coarse material recycling mechanism comprises a receiving hopper, an air cylinder and a telescopic rod, wherein the receiving hopper is arranged at the lower end of the coarse material outlet, and the air cylinder is arranged on a fixed rod and connected with a moving rod; the moving rod is in axial connection with the telescopic rod, and an air cylinder switch is connected to the air cylinder; and the bottom of the receiving hopper is provided with a slide plate and a slipway matched with the slide plate. The crushing device for producing the moulded coal has the beneficial effects that by arranging the coarse material recycling mechanism, not only can continuous operation of a production line be ensured, but also coarse materials can be recycled through recrushing, and coal dust can be prevented from flying through a hopper cover.

Description

technical field [0001] The invention belongs to the field of crushing equipment, in particular to a crushing device used for briquette production. Background technique [0002] In the production line of briquette, the raw coal needs to be pulverized to a particle size of 0-3cm. Generally, the bottom of the crushing device is equipped with a screen with a diameter of 3mm. As a result, the crusher needs to be shut down to remove the large particle size raw coal after running for a period of time, which affects the entire production line, and the large particle size raw coal is removed, resulting in a waste of resources. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a crushing device for briquette production, which enables continuous production without wasting raw materials. [0004] The technical scheme of the present invention is: a crushing device for briquette production, comprising a crushing mechanism, an oscillating mechanism and...

Problems solved by technology

[0002] In the briquette production line, the raw coal needs to be crushed to a particle size of 0-3cm. The bottom of the general crushing device is equipped with a screen with a diameter of 3mm, and the raw coal larger than 3mm is always rolled at the bottom of the crusher. As a result, the crusher needs to be shut down after running for a period of time to remove the large-sized raw coal, which affects the progress of the entire production line, and the large-sized raw coal is removed, resulting in waste of resources
