Description

Heavy slag remover for papermaking production Technical Field The invention relates to the technical field of papermaking equipment, in particular to a heavy slag remover for papermaking production. Background The heavy slag remover body for paper making is a core purifying device in the paper making and pulping process, and the core principle is that the separation of heavy impurities (such as sand, scrap iron, metal particles, hard fiber bundles and the like) and light slurry in paper pulp is realized by utilizing the synergistic effect of centrifugal force and gravity. If the bulletin number is CN203755075U, the bulletin day is 2014 and the patent of 08 and 06, a cyclone paper pulp slag remover body is disclosed, which relates to a fluid separation device and comprises a good pulp outlet, a slag remover main body, a cone, a slag outlet and a back flushing device, wherein the slag remover main body consists of a pulp inlet head and a cone body, the slag remover main body is of a cone structure, and the good pulp outlet, the slag remover main body, the cone, the slag outlet and the back flushing device are sequentially connected from top to bottom. The utility model has the advantages that the bottom axial backwash water technology is applied to the pulp cyclone separation slag remover body, mainly aims at improving the running stability of the slag remover body under higher inlet concentration, reducing the blockage in the running process of the equipment, reducing the content of useful fibers in the separated heavy impurities, and discharging more fibers from a good pulp port, thereby reducing the loss of the fibers and the cost of raw materials, and being very suitable for practical use. In the long-time use process of the existing heavy slag remover body, most of heavy impurities in paper pulp are in high density and large particle forms, part of impurities are easy to form caking due to the adhesion of slurry humidity, when the paper pulp flows in a cone of the heavy slag remover body in a spiral way, the rotation radius of a lower section area is greatly reduced, the flow speed of water is reduced along with the rotation radius, the centrifugal force effect is weakened, the heavy impurities are difficult to continuously take away, accumulation is easily formed at the lower section of the inner wall of the cone, so that a slag discharge port at the bottom of the heavy slag remover body is blocked, in the prior art, the cleaning of the inside of the heavy slag remover body is generally realized by adopting a shutdown disassembly mode, in the disassembly process, paper pulp is often accumulated inside the heavy slag remover body due to the blocking of the slag discharge port, the heavy impurities and the light slurry in the paper pulp cannot be effectively discharged, and therefore the paper pulp can overflow from a disassembly position in the heavy slag remover body, and especially in the high-cost high end of part of the high cost of the paper pulp can cause additional economic loss. Disclosure of Invention The invention aims to provide a heavy slag remover for papermaking production, which aims to solve the defects in the prior art. In order to achieve the purpose, the heavy slag remover for papermaking production comprises a fixing frame and a slag remover body, wherein a grouting main pipe is arranged on the fixing frame, a slurry outlet pipe is arranged at the top of the slag remover body, a slag outlet pipe is arranged at the bottom of the slag remover body, the side surface of the slag remover body is connected with the grouting main pipe, the slag remover body comprises a cylinder, a cone cylinder and a lantern ring, the lantern ring is fixedly connected to the upper end of the cone cylinder, the cylinder and the cone cylinder are detachably connected, the lantern ring is sleeved in the cylinder and is slidably connected to the cylinder, a telescopic pipe is arranged between the cone cylinder and the slag outlet pipe, and the cone cylinder is detachably connected with the telescopic pipe. Preferably, a grouting branch pipe is arranged between the slag remover body and the grouting main pipe, and one end of the grouting branch pipe penetrates through the cylinder and is communicated with the inside of the cylinder. Preferably, the lower end of the cylinder is fixedly connected with a first disc body, the upper end of the cone cylinder is fixedly connected with a second disc body, and the first disc body is connected with the second disc body through bolts. Preferably, the device further comprises a buffer mechanism, wherein the buffer mechanism is used for slowing down the descending speed of the cone barrel after the cone barrel is disassembled. Preferably, the buffer mechanism comprises a sleeve, a fixed rod and a piston, wherein the upper end of the fixed rod is fixedly connected with the lower surface of the first disc body, the piston is fixedly connected with the lower end of the fixed rod
