Description

Technical Field

[0001] The utility model relates to the technical field of sugar beet processing, in particular to a scraper screen for sewage treatment. Background Art

[0002] In the production process of beet sugar enterprises, the water after flowing and washing beets should be recycled to reduce production costs and save water resources. After weeding and stone removal during the flow of beets, the beets need to be thoroughly cleaned. During the flow, washing and transportation of beets, broken beet tails and small pieces of beets accounting for about 1-2% of the weight of the beets can be produced. The water after washing the beets contains beet tails, small pieces of beets, mud and weeds, which must be treated before they can be reused. Beet sugar enterprises have been using tail root catchers to treat flow and washing water. The disadvantage of tail root catchers is that they take up a lot of space. At present, some old enterprises in my country are mainly undergoing technical transformation. Due to space constraints, they cannot use tail root catchers. Therefore, we invented the scraper screen. The biggest advantage of the scraper screen is that it is designed according to the actual spatial position on site to meet production requirements.

[0003] The prior art discloses a new type of screening scraper transfer machine (CN202010174661.1), including a fuselage, the fuselage including a head, a first middle trough, a second middle trough, a third middle trough, and a tail, the second middle trough including a second middle plate and a second bottom plate, the second middle plate including a left plate and a right plate, and the opposite sides of the left plate and the right plate do not contact, the first middle trough including the first middle plate and the first bottom plate, and a plurality of screening holes are provided on the working surface of the first bottom plate, the screening holes are arranged along the length direction of the first bottom plate, and the apertures of the plurality of screening holes gradually increase along the movement direction of the lower chain of the scraper chain.

[0004] The prior art lacks the collection of materials falling through the sieve plate. In order to collect the materials passing through the sieve holes, grates are usually installed to receive the materials. The materials fall on the grates and accumulate, which affects the normal function of the grates and also affects the sedimentation of water, adding a burden to the subsequent cleaning and maintenance operations. Therefore, it is very necessary to clean the grates.

[0005] Therefore, we propose a scraper screen for sewage treatment. Utility Model Content
