Abstract

Present invention relates to dredge pump for sewage treatment, especially a vertical type disintegrable self-suction dredge pump. It features designing impeller as wide-open type structure for increasing pump ability and raising engine efficiency, said wide-open type impeller combined with blade effectively balancing axial force and radial force, topping mechanism set in pump body effectively disintegrating blocky-shaped particle and long fiber substance, setting exhaust valve on pump outlet for exhausting out vapour generated in separating vapour and liquid, setting solenoid valve on pump body suction inlet for preventing siphon affect sucking up water in pump body. Said invention has reasonable structure, compactness, reliable operation, combining disintegrating, exhausting, siphon prevention, and pumping function, and can be widely used in sewage treatment, sewage transference containing easy disintegrating solid particles and long fiber, and ship.

Description

technical field [0001] The invention relates to a sewage pump in the technical field of sewage treatment, in particular to a vertical crushable self-priming sewage pump. Background technique [0002] In the process of sewage treatment, it is inevitable to encounter massive particles and long fiber substances. Due to the existence of these substances, the flow channel of the existing sewage pump impeller is very easy to be blocked and the medium cannot be transported, which affects the pumping equipment. In order to solve the above problems, some foreign pump companies have designed crushable submersible sewage pumps. However, solid particles and long fiber materials will generate a large amount of gas during the crushing process, which will have a certain impact on the performance of the pump. Influenced by the impact, some domestic enterprises use volumetric pumps as the pumping device gas to achieve the purpose of self-priming. Using volumetric vacuum pumps consumes a cert...
