Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral discharge centrifuge technology, specifically a spiral scraper with a multi-functional structure. Background Technology
[0002] The spiral discharge centrifuge is an automatic, continuous filtration centrifuge. During operation, the suspension enters the smaller end of the drum through the feed pipe. The solid phase is trapped by the filter screen mounted on the drum, forming a filter cake. The filtrate is discharged through the small holes or gaps in the filter screen and the holes or grooves on the drum. After being collected by the casing, it is discharged from the drain port. The filter cake moves towards the larger end under the action of the spiral scraper, and finally, under the combined action of gravity and centrifugal force, it is collected by the casing and discharged from the solid discharge port. In existing technologies, during the feeding process between the feed pipe and the accelerating plate, material easily splashes from the gap between the feed pipe and the accelerating plate, directly splashing onto the outer surface of the feed pipe and onto the already separated solids, affecting normal separation. Furthermore, when the washing pipe fills the spiral scraper with washing liquid, the lack of a structure to block the washing liquid easily allows it to splash into the solids already discharged from the larger end of the drum, thus reducing the separation effect. Therefore, a spiral scraper with a multi-functional structure is proposed. Summary of the Invention
[0003] The purpose of this invention is to solve the above problems by proposing a spiral scraper with a multi-functional structure.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional spiral scraper, comprising a scraper body; characterized in that the scraper body is provided with several sets of spiral blades arranged circumferentially to improve the uniformity of discharge, a baffle plate disposed inside the scraper body to prevent washing liquid from splashing onto the filter cake and improving the separation effect, and an accelerating disc to improve the separation efficiency; the accelerating disc is equipped with a sealing ring for sealing between the accelerating disc and the feed pipe, and a sealing pressure plate for fixing the sealing ring.
[0005] Preferably, the scraper body, the baffle plate, and the acceleration disc are integrated into one unit.
[0006] Preferably, the baffle plate and the acceleration disk are conical structures.
[0007] Preferably, the scraper body is also provided with several material outlets and liquid outlets.
[0008] Preferably, it also includes several acceleration ribs disposed on the inner surface of the acceleration disk to improve the accelerated separation of the suspension.
[0009] The beneficial effects of this utility model are as follows: the spiral blades integrated on the scraper body ensure uniform discharge of the filter cake, the baffle plate blocks the washing liquid to prevent it from splashing onto the filter cake and improves the separation effect, and the acceleration disc accelerates the separation of the suspension and improves the efficiency of the suspension separation. Thus, the multifunctionality of the scraper body is improved, and the efficiency and effect of solid-liquid separation are enhanced. By using a sealing ring to seal between the acceleration disc and the sealing plate, material splattering between the acceleration disc and the sealing plate is prevented. Attached Figure Description
