[0002] Artificial boards, also known as synthetic boards and composite boards, are a kind of building material processed from wood or other fiber materials. Artificial boards are widely used and are often used in furniture manufacturing, interior decoration, building structures, packaging, etc.

[0003] When artificial boards are produced and processed, pulping is generally carried out first, which is to soak the raw materials in water and break them into fibers by mechanical or chemical methods. The fibers produced in the pulping process need to be separated and cleaned to improve the fiber quality. Then it is pressed, that is, the pulp is sent to a hot press to solidify it into the shape of a board under high temperature and high pressure. Then the hot-pressed board needs to be placed in a cooling tower for cooling, and then taken out for drying. Then it will be cut according to the designed size, and finally the surface will be sanded, veneered and packaged.

[0004] When pulping artificial boards, wood chips, cellulose, resin and other raw materials are generally put into a mixer barrel and then stirred and mixed into slurry.

[0005] At present, in the existing stirring device used for stirring and pulping artificial boards, the raw materials are easy to agglomerate during stirring, which will greatly reduce the quality of the finished artificial boards produced by hot pressing in the later stage.

[0006] Therefore, an anti-agglomeration stirring device for stirring and pulping artificial boards is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-5A mixer that is not easy to agglomerate comprises a mixer barrel 1, a bottom plate 2 is provided below the mixer barrel 1, a liquid storage tank 21 and a reciprocating cylinder 7 are provided on the bottom plate 2, a feeding pipe 11 and a discharging pipe 12 are provided on the mixer barrel 1, a heating plate 13 is provided in the side wall of the mixer barrel 1, a first liquid injection group 4 and a second liquid injection group 5 are provided on the periphery of the side wall of the mixer barrel 1, a top plate 71 is provided on the piston rod of the reciprocating cylinder 7, and a stirring motor 7 is provided on the top plate 71 2, a stirring shaft 73 is arranged on the motor shaft of the stirring motor 72, a stirring blade 74 is arranged on the stirring shaft 73, a mixing hole 75 is provided on the stirring blade 74, a guide hole 8 is provided on the mixer barrel 1, a smooth layer 81 is provided in the guide hole 8, a liquid pump 22 is provided on the liquid storage tank 21, the first liquid injection group 4 and the second liquid injection group 5 are both composed of a liquid separation ring tube 41 and a liquid injection head 42, the interior of the heating plate 13 is a hollow cavity, and a dry-burning type heating wire is preset in the hollow cavity.

[0027] The piston rod of the reciprocating cylinder 7 can be reciprocated up and down and the distance is adjustable.

[0028] In detail, the first liquid injection group 4 and the second liquid injection group 5 are symmetrically arranged in the upper and lower parts with the horizontal central axis of the mixer barrel 1 as the center, and a connecting pipe 6 is connected between the first liquid injection group 4 and the second liquid injection group 5. The liquid pump 22 is provided with an infusion tube 3, and the infusion tube 3 is connected to the connecting pipe 6, so that the dispersant liquid is injected into the mixer barrel 1 in the form of a ring, further improving the comprehensive contact and mixing of the dispersant liquid and the wood-based panel raw material.

[0029] Furthermore, the top cross-section of the liquid separation ring tube 41 is a circular ring structure, and there are eight liquid injection heads 42 arranged in a circle. The liquid injection heads 42 are connected to the inner cavity of the mixer barrel 1. The liquid injection heads 42 are diffuse horn structures, which further increase the effective injection area of ​​the dispersant liquid.

[0030] Furthermore, a suction pipe 221 is provided at the lower end of the suction pump 22. The suction pipe 221 penetrates into the liquid storage tank 21. The lower end surface of the suction pipe 221 does not contact the bottom inner cavity wall of the liquid storage tank 21, thereby ensuring that the suction pipe 221 effectively extracts the dispersant liquid in the liquid storage tank 21.

[0031] In more detail, the heating plate 13 is embedded in the inner wall of the mixer barrel 1, and the number of stirring blades 74 is eight and they are arranged circumferentially on the outer wall of the stirring shaft 73. The stirring blades 74 are made of cemented carbide tungsten steel and have excellent rigidity to avoid deformation during high-speed rotation.

[0032] In general, the mixing holes 75 are arranged in three groups horizontally, and each group is arranged in five groups vertically. When the stirring blades 74 rotate at high speed, the raw materials of the artificial board and the dispersant liquid will pass through each mixing hole 75, further improving the mixing effect.

[0033] Finally, the guide slide hole 8 is rotatably slidably connected with the stirring shaft 74 through a smooth layer 81. The smooth layer 81 is a graphite powder density coating layer with a smooth and wear-resistant surface, which improves the smoothness of the stirring shaft 73 when it reciprocates up and down and rotates in the guide slide hole 8.

[0034] Working method: the raw materials for making artificial boards are put into the mixer barrel 1 through the feeding pipe 11, and then the valve preset on the feeding pipe 11 is closed. Then, the reciprocating cylinder 7, the stirring motor 72, the liquid pump 22, and the heating plate 13 are started. The liquid pump 22 draws the dispersant liquid preset in the liquid storage tank 21 into the liquid infusion pipe 3 through the liquid pumping pipe 221, and then the dispersant liquid is input to the liquid separation ring pipe 41 through the connecting pipe 6. Finally, the dispersant liquid is fully injected into the mixer barrel 1 through each injection head 42. At the same time, the stirring motor 72 drives the stirring shaft 73 to drive the stirring The stirring blade 74 rotates at a high speed, and the reciprocating cylinder 7 drives the high-speed rotating stirring blade 74 to move up and down at a certain vertical reciprocating distance. At this time, the stirring blade 74 that moves up and down and has a mixing hole 75 can effectively and comprehensively stir and mix the raw materials of the artificial board and the injected dispersant liquid. At the same time, the started heating plate 13 can effectively heat the raw materials of the artificial board and the dispersant liquid, which greatly reduces the tension and viscosity between the raw materials, improves the fluidity between the raw materials, and effectively improves the anti-agglomeration property during the stirring process of the raw materials of the artificial board.

[0035] In addition, by providing a guide slide hole 8 structure with a smooth layer 81 on the mixer barrel 1, the smoothness of the stirring shaft 73 when it reciprocates up and down and rotates in the guide slide hole 8 is further improved, thereby ensuring a smooth stirring effect on the raw materials of the artificial board.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
