Embodiment Construction

[0016] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is only used to explain the present invention and does not constitute a limitation to the protection scope of the present invention.

[0017] The tube belt machine is driven by two 800KW motors at the head and two 800KW motors at the tail. The material is fed from the tail of the tube belt machine and transported to the head of the tube belt machine through the tubular belt 1 for unloading. At the head drive drum 1 and 2 of the pipe belt machine, after the tubular belt 1 is cleaned by the first-level scraper cleaner 3 and the second-level scraper cleaner 4, it passes through the reversing drum 5 and the drive drum 2 A cleaning device is installed under the tubular belt 1 in the transition section at the top. There are two rows of high-pressure water cleaning n...

Abstract

The invention discloses a cleaning method of a phosphorous gypsum conveying-pipe-shaped belt. A motor drives pipe belt machine equipment; after feeding, the pipe-shaped belt conveys materials to the head portion of the pipe belt machine to discharge; a first grade scraper plate sweeper and a second grade scraper plate sweeper are placed on the position of a transmission rolling drum on the head portion of the pipe belt machine to clean the pipe-shaped belt, a cleaning device is installed below the pipe-shaped belt of a transition section of the head portion of the pipe belt machine through a turnabout rolling drum and a second transmission rolling drum to clean and dry the pipe-shaped belt. Dregs and water after the pipe-shaped belt is washed are connected through a water-collecting tank below a cleaning nozzle, and are connected to cycling settling basin through a pipeline. Supernatant water is used as water for cleaning the pipe-shaped belt, and the pipe-shaped belt is cleaned circularly through a water pump. The cleaning method of the phosphorous gypsum conveying-pipe-shaped belt can effectively clean an acidic material of the phosphorous gypsum on the pipe-shaped belt, wherein crystal water is included in the acidic material of the phosphorous gypsum, guarantee cleaning operations of the pipe-shaped belt, ensure that materials are not adhered to a carrier roller, resistance of the pipe-shaped belt is not increased, operation cost is reduced, equipment is safely operated and is not corroded by acid.

Description

technical field [0001] The invention relates to a method for cleaning a phosphogypsum conveying tubular belt. Background technique [0002] Currently, in the production of phosphate fertilizers, the production of phosphoric acid will produce a large amount of phosphogypsum. Because the amount of phosphogypsum is large and cannot be completely recycled, it is usually transported to the phosphogypsum yard by a tubular belt dry method for storage. During the operation of the tubular belt, the tubular belt should be prevented from being hanged and scratched by the sticky material of the idler. Since the transported material phosphogypsum contains crystal water and residual phosphorus, the moisture content is about 25%, the residual phosphorus content is about 1%, and the pH ≈ 2, it is acidic, so it should be transported by dry method. However, during the transportation of phosphogypsum, due to the presence of crystal water and acidic substances, some materials still stick to t...
