[0014] The present invention provides a slurry discharge structure, a slurry inlet structure, a slurry pump and a double-cavity disk. The slurry pump fills the slurry in the slurry making cylinder into the cavity above through the cavity and the slurry inlet structure. The slurry in the cavity is ejected from the slurry discharge structure. When the double-cavity disk rotates, the slurry inlet structure is driven to pump the slurry at different positions in the slurry making cylinder into the cavity.

Pulp enters the double-headed nozzle through the vertical cylinder, the rotating cylinder and the vertical axis. The double-headed nozzle sprays pulp during rotation. The sprayed pulp impacts the raw material in the pulping cylinder. The flow generated by the impact increases the effect of raw materials at different levels.

[0016] The present invention arranges a stirring plate, and when the double-cavity disk rotates, the stirring plate is driven to rotate around the axis of the double-cavity disk through the horizontal cylinder, the meshing ring and the vertical shaft. Since the stirring plate is arranged upwardly, when the stirring plates on both sides of the vertical shaft rotate around the axis of the double-cavity disk, the stirring plates on both sides of the vertical shaft can respectively push the slurry to flow up and down, thereby assisting the mixing of slurries at different levels up and down.

[0017] The present invention drives the reciprocating screw to rotate synchronously when the double-cavity disk rotates by arranging a reciprocating screw, an arc-shaped bevel gear plate, an engaging plate and an engaging ring. When the driven bevel gear D connected to the reciprocating screw meshes with the corresponding bevel gear plate, the reciprocating screw is driven to rotate a certain angle. When the engaging plate and the engaging ring mesh with the corresponding rotating reciprocating screw, they move to a certain extent, changing the distance between the vertical cylinder and the engaging ring and the axis of the double-cavity disk, so that the stirring plate can stir the slurry within different distance ranges from the double-cavity disk. At the same time, when the vertical cylinder moves, it can respectively change the distance between the connected slurry outlet structure and slurry inlet structure and the double-cavity disk.

[0034] The two slurry-passing structures 5 are fixedly connected to a vertical cylinder 9 at one end located outside the double-cavity disk 2. The lower ends of the two vertical cylinders 9 are respectively installed with a slurry outlet structure 7 and a slurry inlet structure 8. The slurry outlet structure 7 is connected to the interior of the cavity 4 located above the double-cavity disk 2, and the slurry inlet structure 8 is connected to the interior of the other cavity 4.

A spiral feeding plate 83 is inserted into the inner rotation of the inner cylinder 82. The upper end of the spiral feeding plate 83 is fixed to the lower end of the adjacent driven bevel gear A11, and the slurry can be transported upward when the spiral feeding plate 83 rotates.

[0036] The two active bevel gears A12 are both rotatably sleeved with a meshing plate 13, and the lower ends of the two meshing plates 13 are respectively fixed to the upper ends of the two vertical cylinders 9. A prism shaft 14 is slidably inserted at the axis of each active bevel gear A12, and one end of the prism shaft 14 close to the axis of the double-cavity disk 2 is rotatably connected to the upper surface of the double-cavity disk 2, and the other end of the prism shaft 14 is coaxially fixed with a driven bevel gear B15. The two driven bevel gears A11 are respectively connected to the pulp outlet structure 7 and the pulp inlet structure 8. The two driven bevel gears B15 are meshed with a bevel gear ring 16 at the bottom, and the two bevel gear rings 16 are fixedly inserted in the pulping cylinder 1.

Two arc-shaped bevel gear plates 613 are fixedly inserted inside the pulping cylinder 1, and the two arc-shaped bevel gear plates 613 are staggered up and down. When the reciprocating screws 611 on both sides of each cavity 4 rotate around the axis of the double-cavity disk 2, the driven bevel gears D612 on the upper and lower sides intermittently mesh with the arc-shaped bevel gear plates 613 distributed up and down, driving the reciprocating screw 611 to rotate intermittently, and the meshing plate 13 and the meshing ring 61 are respectively meshed with the corresponding reciprocating screw 611 to control the change in the distance between the meshing plate 13 and the meshing ring 61 and the axis of the double-cavity disk 2.

[0037] The pulp discharge structure 7 includes a rotating drum 71 and a concentric shaft 72. The concentric shaft 72 is coaxially located inside the rotating drum 71. The upper end of the rotating drum 71 is fixedly sleeved on the lower end of the adjacent driven bevel gear A11. The upper end of the rotating drum 71 is rotatably inserted into the interior of the adjacent vertical cylinder 9. The rotating drum 71 is connected to the interior of the vertical cylinder 9. The driven bevel gear A11 is rotatably sleeved on the outer surface of the concentric shaft 72.

The driven bevel gear C74 and the driving bevel gear C75 are located inside the adjacent protective cover 731. The protective cover 731 protects the internal driven bevel gear C74 and the driving bevel gear C75 to prevent the slurry from entering between the driven bevel gear C74 and the driving bevel gear C75. One end of the vertical shaft 73 located outside the rotating drum 71 is fixedly connected with a double-headed nozzle 76. The shape of the double-headed nozzle 76 is an arc shape. When the vertical shaft 73 rotates with the rotating drum 71, the driven bevel gear C74 and the driving bevel gear C75 are connected. C75 is engaged, and the double-headed nozzle 76 is driven to rotate around the axis of the vertical shaft 73 through the vertical shaft 73, so that the direction of the slurry flow sprayed from both ends of the double-headed nozzle 76 is constantly changed. The vertical shaft 73 is connected to the middle part of the double-headed nozzle 76.

[0039] The working principle is as follows: the motor 17 drives the double-cavity disk 2 to rotate relative to the pulping cylinder 1. When the double-cavity disk 2 drives the vertical cylinder 9 to rotate relative to the axis of the double-cavity disk 2 through the horizontal cylinder 10, the prism shaft 14 drives the driven bevel gear B15 to mesh with the bevel gear ring 16 to generate rotation. The prism shaft 14 drives the active bevel gear A12 to rotate and mesh with the driven bevel gear A11. When the two driven bevel gears A11 rotate, they respectively drive the spiral feed plate 83 and the rotating cylinder 71 to rotate. The push plate 57 applies pressure to the angle plate 56 located in the inner part of the cavity 4, so that the blocking plate 54 is disengaged from the blocking of the matching pulp groove 53, so that the interior of the movable cylinder 51 is connected with the cavity 4 through the pulp groove 53, and the pulp enters the interior through the gap of the outer gap cylinder 81. When the spiral feed plate 83 rotates, it pushes the pulp into the vertical cylinder 9 and the connected movable cylinder 51, and then enters the cavity 4 below through the pulp groove 53. The pulp pump 3 fills the cavity below The slurry in 4 is drawn into the upper cavity 4, and then filled into the upper movable cylinder 51 and the vertical cylinder 9 through the corresponding slurry groove 53. The slurry enters the rotating cylinder 71 from the vertical cylinder 9, and then enters the double-headed nozzle 76 through the vertical shaft 73. With the subsequent filling of slurry, the slurry is sprayed out from both ends of the double-headed nozzle 76, and the sprayed pulp impacts the raw material in the pulping cylinder 1, so that the slurries at different levels are mixed. The rotating cylinder 71 drives the vertical shaft 73 to rotate relative to the concentric shaft 72, and the driven bevel gear C74 meshes with the active bevel gear C75 when following the rotation of the vertical shaft 73. The vertical shaft 73 drives the double-headed nozzle 76 to rotate around the axis of the vertical shaft 73. The double-headed nozzle 76 can spray slurry flows in different directions. When the stirring plates 63 on both sides of the vertical shaft 62 rotate around the axis of the double-cavity disk 2, the stirring plates 63 on both sides of the vertical shaft 62 can respectively push the slurry to flow up and down, thereby assisting the mixing of slurries at different levels up and down.

[0040] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
