Detailed Embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1 to 5 , a pulper, comprising a tank body 100. The top of the tank body 100 is open, and the bottom of the tank body 100 is a conical structure. A discharge port is connected to the side surface of the conical structure. A first support ring 110 and a second support ring 120 are arranged inside the tank body 100, and the first support ring 110 is located above the second support ring 120. A first pulping disc 200 is installed on the first support ring 110, a second pulping disc 300 is installed on the second support ring 120, and a driving disc 400 is arranged at the bottom of the tank body 100 at the same time. The tank body 100 is lifted by a bracket, and a motor 500 is arranged below the tank body 100. The output shaft of the motor 500 is connected to the driving disc 400 to drive the rotation of the driving disc 400.

[0025] Both the first pulping disc 200 and the second pulping disc 300 are provided with a flow guide, and blades 230 are also installed on both of them. A first connecting rod 210 is connected to the upward side of the first pulping disc 200, a second connecting rod 220 is connected to the downward side of the first pulping disc 200, the second connecting rod 220 is connected to the second pulping disc 300, a third connecting rod 310 is connected to the downward side of the second pulping disc 300, and the third connecting rod 310 is connected to the driving disc 400. The rotation of the driving disc 400 can drive the rotation of the first pulping disc 200 and the second pulping disc 300, so as to break the pulp.

[0026] There are two third connecting rods 310. Two connecting grooves 410 corresponding to the two third connecting rods are arranged on the edge of the driving disk 400. The third connecting rods are inserted into the connecting grooves 410, so that the second pulping disk 300 is connected to the driving disk 400. The two third connecting rods 310 can ensure the stability of torque transmission between the driving disk 400 and the second pulping disk 300, and prevent the third connecting rods 310 from slipping by themselves during rotation. One end of the second connecting rod 220 is fixedly connected to the first pulping disk 200, and the other end is fixedly connected to the second pulping disk 300, which can ensure the stability of the connection between the first pulping disk 200 and the second pulping disk 300. At the same time, the second connecting rod 220 is located at the centers of the first pulping disk 200 and the second pulping disk 300, which can reduce the influence on the installation of the blades 230. The first connecting rod 210 is located at the center of the first pulping disk 200, which can also reduce the influence on the installation of the blades 230 on the first pulping disk 200. Through the first connecting rod 210, it is convenient to take out the first pulping disk 200 and the second pulping disk 300 from the tank body 100, so as to facilitate the cleaning of the fibers accumulated on the blades 230 and the diversion holes 202, thereby ensuring the pulping efficiency.

[0027] The first support ring 110 is provided with a first guiding ring 111. A first guiding groove 201 that cooperates with the first guiding ring 111 is arranged on the downward surface of the first pulping disk 200. The first guiding ring 111 is embedded in the first guiding groove 201 and is in sliding contact with the first guiding groove 201. The second support ring 120 is provided with a first guiding ring 111. A second guiding groove 301 that cooperates with the second guiding ring 121 is arranged on the downward surface of the second pulping disk 300. The second guiding ring 121 is embedded in the second guiding groove 301 and is in sliding contact with the second guiding groove 301. The cross-sections of the first guiding ring 111 and the second guiding ring 121 are both trapezoidal structures, and the cross-sections of the first guiding groove 201 and the second guiding groove 301 are corresponding trapezoidal structures, so as to facilitate the installation of the first pulping disk 200 and the second pulping disk 300 and ensure the stability of rotation.

[0028] Mounting grooves 240 for installing the blades 230 are arranged on the upward surfaces of the first pulping disk 200 and the second pulping disk 300. Connecting blocks 231 that can be inserted into the mounting grooves 240 are arranged at the bottoms of the blades 230, so as to facilitate the installation and disassembly of the blades 230. When the first pulping disk 200 and the second pulping disk 300 are taken out from the tank body 100, the blades 230 can be removed from the first pulping disk 200 and the second pulping disk 300 for further cleaning.

[0029] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
