Description

Technical Field

[0001] The present application relates to the technical field of cement clinker conveying and recycling, and in particular to a cement clinker conveying and recycling device. Background Art

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay and iron raw materials in appropriate proportions, burning them until they are partially or completely melted, and cooling them. Cement clinker is the main raw material for making cement. In cement clinker production plants, conveyor belts are mostly used for transportation and recycling of the produced cement clinker. Since the materials inside the cement clinker have a certain degree of adhesion, part of the cement clinker will adhere to the conveyor belt when conveying it with a conveyor belt. At present, some conveyor belt scraping devices lack the buffering performance of movement when in use, which will cause damage to the conveyor belt when scraping the conveyor belt.

[0003] In order to solve the above problem, a cement clinker processing conveying and recovery device is disclosed in the patent announcement with announcement number CN219278656U, which includes a placement plate, an adjustment component and a buffer scraper component. A support rod is fixedly installed on the top of the placement plate, a mounting plate is fixedly installed on the top of the support rod, the adjustment component includes a fixed plate, a longitudinal mounting plate and a threaded rod, and a fixed plate is fixedly installed on the bottom of the mounting plate. The number of fixed plates is two groups. The cement clinker processing conveying and recovery device can make the scraper plate have a certain elasticity during the scraping process through the coordinated use of the connecting plate, the buffer spring and the sliding rod, and the arc-shaped setting on the top of the scraper plate can effectively prevent the scraper plate from scratching or damaging the conveyor belt during the scraping process, thereby protecting the conveyor belt to a certain extent.

[0004] In actual use, it was found that the above-mentioned related schemes still have at least the following shortcomings: when the cement clinker is transported by a conveyor belt, when the cement clinker is transported to the end of the conveyor belt, all the cement clinker will fall into a collecting box. Since the volume of cement clinker varies, it is not possible to screen the cement clinker and screen out the large pieces of cement clinker. When the cement clinker is subsequently recycled and used, it is often necessary to screen the cement clinker in the collecting box again. Therefore, we propose a cement clinker transportation and recovery device to solve the above problems. Utility Model Content
