[0002] The vacuum pulp washer is a common pulp washing device, and the pulp is generally fine wood pulp fibers or pulp fibers. The purpose is to wash and remove the chemical solvents contained in the pulp by means of vacuum water washing to achieve the purification effect. The method is to lay the pulp flat on the filter plate and wash it with clean water or demineralized water multiple times to fully dilute and dissolve the chemical solvents in the pulp. Through the negative pressure generated by the vacuum pump, the water contained in the pulp is drained, and then through the combined action of the pulp stripping device, wire cloth washing device, water replenishing device, etc. at the discharge port, it is remixed into a pulp aqueous solution.
[0003] At present, the wire cloth cleaning devices used on the market generally adopt the flushing method. The flushing equipment is generally designed relatively simply and is easy to operate. However, due to the large number of fine fibers contained in the pulp of the wire cloth, during the long-term use of the impact equipment, it is inevitable that the mesh holes of the wire cloth will be blocked, resulting in a decrease in the water permeability, poor cleaning effect, and the pulp needs to be repeatedly cleaned, resulting in an increase in water consumption and high energy consumption. Moreover, the blocked wire cloth needs to be replaced frequently, increasing the cleaning cost.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure, and an automatic cleaning device for the wire cloth of a vacuum pulp washer is provided with the expectation of achieving a more practical value. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0028] Embodiment 1:
[0029] Please refer to Figure 1 - Figure 4, An automatic cleaning device for the wire cloth of a vacuum pulp washing machine, comprising a tank body 8, a support body 1 and a spray pipe 3. A pipe with a flange is fixed at the water outlet position of the tank body 8, and a multi-stage centrifugal pump 7 is connected through the pipe with a flange. A first motor 9 is fixedly installed at the control end of the multi-stage centrifugal pump 7. The output end of the multi-stage centrifugal pump 7 is installed with a hose 6 through a flange. Both ends of the spray pipe 3 are provided with connection ends. One end of the hose 6 away from the multi-stage centrifugal pump 7 is fixed to the first connection end of the spray pipe 3. A plurality of nozzles 4 are fixedly installed on the side of the spray pipe 3. A guide wheel 5 is arranged on the side of the first connection end of the spray pipe 3. A reciprocating connecting rod structure 2 is installed between one end of the support body 1 and the second connection end of the spray pipe 3;
[0030] A reduction gearbox 11 is fixedly installed on the top of the support body 1. A second motor 10 is fixedly installed at the top end of the reduction gearbox 11. The output end of the second motor 10 passes through the reduction gearbox 11 and is connected with a universal coupling 12 through a coupling. One end of the universal coupling 12 is fixed to one of the rotation centers of the reciprocating connecting rod structure 2.
[0031] Refer to Figure 1 , Specifically, the length of the spray pipe 3 is 3000 mm. According to the width of the wire cloth of 2200 mm, it is determined that the length of the spray pipe 3 is 3000 mm, which can ensure the coverage of the cleaning surface of the wire cloth.
[0032] Refer to Figure 1 , Specifically, the pipe diameter of the connection end of the spray pipe 3 is smaller than the pipe diameter of the spray pipe 3. To avoid possible wear when the spray pipe 3 passes through the guide wheel 5 and contacts the connection end of the guide wheel 5 and the spray pipe 3. In this way, the wear and damage of the spray pipe 3 can be avoided.
[0033] Refer to Figure 1 , Specifically, the interval distance between two adjacent nozzles 4 is 200 mm, and all the nozzles 4 are evenly distributed in a row on the spray pipe 3, and the nozzles 4 are of a shower-type spray structure. Under the reciprocating motion of the reciprocating connecting rod structure 2, the single transverse movement distance of the spray pipe 3 is not less than 200 mm. In this way, by controlling the interval distance between two adjacent nozzles 4 to be 200 mm, it can effectively ensure that each position on the cleaning surface of the wire cloth can be effectively cleaned.
[0034] Refer to Figure 1 , Specifically, the hose 6 is supported by a high-pressure resistant rubber hose, its length is 1500 mm, and both ends of the hose 6 are provided with external thread joints. The length of the external thread joints is one inch, and the pressure resistance strength is 30 kg. Such a flexible connection method can enable the spray pipe 3 to move back and forth. At the same time, it ensures the stability of the connection at both ends of the hose 6.
[0035] Refer to Figure 1 、 Figure 2 、 Figure 3 andFigure 4 , specifically, the reciprocating connecting rod structure 2 includes an end rocker 201. The rotation center point of the end rocker 201 is movably connected to the support body 1 through a rotating shaft. One end of the universal coupling 12 is fixed to the rotation center point of the end rocker 201. The middle part of the support body 1 is movably connected with a middle rocker 202 through a rotating shaft. A first movable rocker 203 is movably connected between the end rocker 201 and the middle rocker 202 through a rotating shaft. A second movable rocker 204 is movably connected between the middle rocker 202 and the second connection end of the spray pipe 3. When the reciprocating connecting rod structure 2 is in use, when the universal coupling 12 rotates, it controls the rotation of the rotation center of the end rocker 201. Under the transmission of the first movable rocker 203, the middle rocker 202 and the second movable rocker 204 of the reciprocating connecting rod structure 2, the spray pipe 3 and its second connection end can be controlled to move.
[0036] Specifically, a limit sliding groove 101 is opened at one end of the support body 1. The second connection end of the spray pipe 3 slides inside the limit sliding groove 101. The limit sliding groove 101 restricts the moving direction of the spray pipe 3 and its second connection end. In this way, the reciprocating movement of the spray pipe 3 and its second connection end can be realized by the active control of the reciprocating connecting rod structure 2.
[0037] Working principle:
[0038] During the spray cleaning operation of the mesh cloth, the spray pipe 3 covers the surface to be cleaned of the entire mesh cloth. At this time, the cleaning water is provided by the tank body 8. The multi-stage centrifugal pump 7 cooperates with the first motor 9 to control the water flow rate. The water in the tank body 8 sequentially passes through the multi-stage centrifugal pump 7, the hose 6, and reaches the inside of the spray pipe 3, and then sprays out from the nozzle 4 of the spray pipe 3 to clean the surface of the mesh cloth.
[0039] At the same time, the second motor 10 works, cooperates with the universal coupling 12 to control the rotation of the end rocker 201 in the reciprocating connecting rod structure 2. Then, under the transmission of the first movable rocker 203, the middle rocker 202 and the second movable rocker 204 of the reciprocating connecting rod structure 2, the spray pipe 3 and its second connection end can be controlled to reciprocate inside the limit sliding groove 101. In this way, the nozzle 4 can be controlled to reciprocate, realizing the reciprocating spray cleaning of the surface of the mesh cloth and avoiding the occurrence of cleaning dead corners.
[0040] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
