Improved hydraulic slag remover

Technical Field

The utility model relates to a paper pulp slag removal equipment field, concretely relates to water conservancy slag removal machine after improvement.

Background

In the pulping and papermaking industry, the conventional pulp is mainly disintegrated in a hydrapulper, the hydrapulper is a common device for disintegrating waste paper pulp, various waste cardboard paper raw materials are preliminarily sorted, added to a chain scraper conveyor according to a certain proportion and continuously conveyed to the hydrapulper for disintegration. According to the concentration requirement in the process of the pulping, pulping white water is continuously added, the rotor rotates at a high speed to play a strong stirring role on the pulp to be subjected to the pulping, the rotor is matched with the cutter head to play a tearing role on the waste paper, meanwhile, the high-strength hydraulic turbulence and shearing action is beneficial to strengthening the waste paper pulping and fiber dissociation, the waste paper raw material is treated by the hydraulic pulper, and the contained paper fiber is dissociated and separated from impurities in the waste paper to form a mixture of paper pulp and impurities. The rope twisting machine is used for removing part of larger light garbage sundries by a method of winding strip sundries and part of non-strip sundries on a cable in rotation, and the large light garbage sundries are wound to form a twisted rope to be discharged outside the system; the small cloth strips, the plastic blocks, the foam blocks, the uncrushed paper sheets and the large heavy sundries are driven by the rotor to rotate and turbulence at a high speed in the pulper, the heavy sundries easily enter the sediment well from the chute on the side surface of the pulper under the action of centrifugal force, the heavy sundries are discharged from the bottom of the sediment well, the small garbage sundries such as the cloth strips, the plastic blocks, the foam blocks and the like and the uncrushed paper sheets enter the hydraulic slag removing machine from the upper part of the sediment well through a pipeline, the paper sheets are secondarily disintegrated, the garbage sundries are separated from paper pulp, the good pulp flows back to the pulper, and the light slag is discharged through a drum screen. The existing pulper is in the process of disintegrating, because overhaul observation window dismouting is troublesome, be unfavorable for in time clearing up the waste residue that adheres to at shells inner wall, and simultaneously, current water conservancy scarifier does not set up the blowoff valve alone, when causing water conservancy scarifier to break down, the inside ponding debris of water conservancy scarifier can't be got rid of, lead to unable maintenance and routine maintenance alone to water conservancy scarifier, influence production normal operating, and because the blade disc position is fixed in the water conservancy scarifier, the blade disc influences secondary disintegration after using wearing and tearing, and can't in time adjust blade disc and sieve clearance and obtain best operational effect, when meetting to be blockked up by debris between blade disc and the sieve clearance, appear the card sediment phenomenon, can lead to the operation load big, lead to the jump even, can only shut down the back and take apart the processing, waste time and energy, and influence production.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, chinese patent literature discloses a hydraulic slag removal machine [ CN201810033855.2], which includes a housing, the housing is provided with a paddle inlet, a water inlet, a light impurity outlet, a heavy impurity outlet, a paddle outlet and an observation port, the observation port is provided with an observation window, and is characterized in that: be equipped with first bulge loop on the lateral wall of viewing aperture, the observation window is equipped with the second bulge loop with the looks gomphosis of viewing aperture, and the lateral wall of second bulge loop offsets with the inside wall of first bulge loop, and the lateral wall of first bulge loop articulates there are a plurality of fixed plates, and the fixed plate includes first board, sets up perpendicularly in the second board of first board tip, and the pin joint of fixed plate is located the tip of first board, and the second board is used for deviating from one side looks butt of second bulge loop with the observation window.

Above-mentioned scheme has solved the maintenance observation window dismouting of hydraulic slag remover among the prior art inconvenient to a certain extent, influences the problem of overhauing, but this scheme still has a great deal of not enough, for example: the existing hydraulic slag remover is not provided with a blow-down valve independently, so that the blow-down is inconvenient, the maintenance is influenced, the position of a cutter head cannot be adjusted, and the blockage is easy to generate.
