Dehydrator shaft roller welding structure

Abstract

The invention discloses a dehydrator shaft roller welding structure comprising a shaft barrel, shaft head components are installed at the two ends of the shaft barrel; each shaft head component comprises a shaft head, a rib plate and a sealing plate, wherein the rib plate is welded to the outer circumferential wall of the shaft head, and the outer end of the rib plate abuts against the limiting end of a mounting groove, a sealing plate mounting table is arranged at the inner end part of the shaft head, the sealing plate mounting table is sleeved with the sealing plate, and the sealing plate ishermetically welded and connected with the sealing plate mounting table of the shaft head by adopting full-circumference welding, the outer diameter of the sealing plate and the outer diameter of therib plate are positioned on the same plane, the shaft head component is inserted into the shaft barrel, and the rib plate and the sealing plate of the shaft head component are respectively welded with the inner wall of the shaft barrel to form an integral structure, a cover plate is sleeved on the shaft head on the outer end surface of the rib plate, and is hermetically welded with the shaft barrel to form an integral structure. The situation of dehydrator shaft roller head weld joint breakage caused by pressure increase can be effectively avoided, and finally the problems that the dehydratorwork efficiency is reduced due to shaft roller head weld joint breakage and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of dewatering machine shaft rolls, and in particular relates to a welding structure suitable for dehydration machine shaft rolls with a diameter greater than 160mm. Background technique [0002] Sludge is an inevitable product of sewage treatment in sewage treatment plants and sewage stations. Untreated sludge entering the environment will directly bring secondary pollution to water bodies and the atmosphere, and it will also affect the ecological environment and human activities. would pose a serious threat. Therefore, sludge should be treated with great care. Sludge is mainly treated by sludge dewatering process. At present, the dehydrators on the market are mainly divided into three types: centrifugal dehydrator, belt dehydrator and spiral ring dehydrator. We are now talking about belt dehydrators. [0003] At present, there are various problems in the belt dehydrator on the market. From the principl...
