Abstract

The invention discloses a slurry circulating pump inlet filtering device, and relates to the technical field of slurry circulating pumps, the slurry circulating pump inlet filtering device comprises a device main body, the upper part of one side of the device main body is connected with a liquid inlet, the bottom of the device main body is provided with a liquid outlet, the interior of the device main body is connected with a first filter screen, and the top of the device main body is provided with a cleaning assembly; disassembly and assembly assemblies are arranged on the two sides of the bottom of the device body. Through a liquid leakage groove, a second filter screen, collection boxes, an ejector rod, a sealing block, a telescopic rod, a spring and a sealing cylinder, impurities blocked by the first filter screen are collected through the arrangement of the two collection boxes so as to facilitate subsequent unified treatment, and meanwhile, slurry in the collection boxes can conveniently return to the device through the arrangement of the liquid leakage groove and the second filter screen; when the impurities need to be taken out, the bolts on the collecting box are screwed off to finish limiting of the collecting box, then the collecting box is pulled out downwards, the impurities in the collecting box can be treated, the impurities in the device can be taken out without shutdown, and operation is easy, convenient and fast.

Description

technical field [0001] The invention relates to the technical field of a slurry circulating pump, in particular to an inlet filtering device for a slurry circulating pump. Background technique [0002] The slurry circulating pump is one of the most important equipment in the desulfurization system of the thermal power plant. It is mainly used to continuously circulate the slurry in the absorption tower, so that the sulfur dioxide in the flue gas can be completely absorbed. When using the slurry circulating pump, a pre-filter device is required. , to prevent impurities from entering the slurry circulating pump, resulting in the reduction of the gap between the impeller and the pump body, so as to avoid the aggravation of impeller wear and prolong the service life of the slurry circulating pump. [0003] The existing slurry circulating pump inlet filter device has accumulated impurities inside the device after being used for a long time, so the device needs to be disassembled ...
