Description

Technical Field

[0001] This application relates to the field of pulping equipment technology, and in particular to a pulping equipment for paper product raw materials. Background Technology

[0002] A paper product raw material pulping device is a mechanical device used to crush and mix raw materials such as waste paper and cardboard into pulp. It is commonly used in the papermaking or paper recycling industry. Its core function is to break down the raw materials into fibrous form through mechanical force and mix them with water to form a uniform pulp, providing the basic material for subsequent papermaking or forming processes.

[0003] During operation, the raw materials are first fed into the feed inlet of the device and then crushed and stirred by the rotating rotor. At the same time, water or other chemical agents are added to promote fiber separation. However, when it is necessary to take out the raw materials after stirring, the water and pulp continue to mix in the container without being separated, resulting in an excessively high water content in the extracted pulp, which increases the difficulty of transporting the raw materials. Utility Model Content

[0004] The paper product raw material pulping device provided in this application adopts the following technical solution:

[0005] A pulping device for paper product raw materials includes a base plate, a telescopic rod fixedly connected to the top of the base plate, an equipment box fixedly connected to the top of the telescopic rod, a motor fixedly connected inside the equipment box, a first conical tooth fixedly connected to one end of the motor, a second conical tooth meshing with one side of the first conical tooth, a first gear fixedly connected to the bottom of the second conical tooth, a second rotating rod fixedly connected to the bottom of the first gear, a rotating sleeve rotating on the outer surface of the second rotating rod, a top plate fixedly connected to the outer surface of the rotating sleeve, a filter barrel fixedly connected to the bottom of the top plate, and an outer barrel provided on the outer side of the filter barrel.

[0006] Preferably, a second gear is meshed with both sides of the first gear, a first rotating rod is fixedly connected to the bottom of the second gear, a grinding wheel is fixedly connected to the outer surface of the first rotating rod, a second rotating rod is fixedly connected to the bottom of the first gear, and a cutter is fixedly connected to the surface of the second rotating rod.

[0007] Preferably, a fixing frame is fixedly connected to the outer wall of the outer tub, and a drain pipe is fixedly connected to the bottom of the outer tub.

[0008] Preferably, the outer surface of the grinding wheel is provided with a plurality of protrusions, which are distributed in a spiral shape, and the cutting edge of the cutter is serrated.

[0009] Preferably, the inner wall of the rotating sleeve is provided with a lubricating layer, and the rotating sleeve and the second rotating rod are connected by a bearing to achieve stable rotation of the second rotating rod relative to the rotating sleeve.

[0010] Preferably, the diameter of the first gear is smaller than the diameter of the second gear.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. After pulping, there is no need to transfer materials. By controlling the extension rod to extend upwards and lift the filter barrel, the filter barrel is lifted out of the pulp in the outer barrel. The raw pulp remains in the filter barrel, and the water flows back to the outer barrel through the filter barrel's filter holes, achieving effective separation of raw pulp and water. This solves the problems of difficult separation and high pulp moisture content in traditional devices and reduces the difficulty of transporting raw materials.

[0013] 2. The spiral protrusions on the outer surface of the grinding wheel exert a squeezing and kneading effect on the crushed raw material during rotation, pushing the raw material axially to make it evenly contact the grinding wheel and promote fiber separation; the serrated blade of the cutter increases the contact area with the raw material and improves cutting efficiency; at the same time, the diameter of the first gear is smaller than that of the second gear, which reduces the rotational speed of the second gear and increases the grinding torque, ensuring more thorough fiber separation. These factors optimize the crushing and grinding process and improve the pulp quality. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Reference Figure 1-4 This utility model provides a pulping device for paper product raw materials, including a base plate 1, a telescopic rod 101 fixedly connected to the top of the base plate 1, an equipment box 102 fixedly connected to the top of the telescopic rod 101, a motor 2 fixedly connected inside the equipment box 102, a first conical tooth 201 fixedly connected to one end of the motor 2, a second conical tooth 202 meshing with one side of the first conical tooth 201, a first gear 203 fixedly connected to the bottom of the second conical tooth 202, a second rotating rod 206 fixedly connected to the bottom of the first gear 203, a rotating sleeve 207 rotating on the outer surface of the second rotating rod 206, a top plate 3 fixedly connected to the outer surface of the rotating sleeve 207, a filter barrel 301 fixedly connected to the bottom of the top plate 3, and an outer barrel 4 provided on the outer side of the filter barrel 301.

[0021] During the pulping stage, motor 2 starts, transmitting power to the first gear 203 and the second rotating rod 206 through the meshing of the first conical tooth 201 and the second conical tooth 202. The second rotating rod 206 drives the cutter 208 on its surface to rotate at high speed, cutting and shredding the paper product raw materials in the filter barrel 301. At the same time, power is transmitted to the top plate 3 through the rotating sleeve 207, driving the filter barrel 301 to rotate slowly inside the outer barrel 4, which plays a stirring role and promotes fiber separation. After pulping is completed, when solid-liquid separation is required, the control telescopic rod 101 extends upward to lift the filter barrel 301, and the filter barrel 301 is lifted out of the pulp in the outer barrel 4. At this time, the filter barrel 301 carries the shredded raw pulp, while the separated water flows back to the stationary outer barrel 4 below through the filter holes of the filter barrel 301 due to gravity, thus realizing the separation of raw pulp and water.

[0022] After pulping, there is no need to transfer the material. It can be directly dewatered through the lifting filter tank 301, which solves the problems of difficult separation and high moisture content of pulp in traditional devices.

[0023] In a preferred embodiment, a second gear 204 is meshed with both sides of the first gear 203, a first rotating rod 205 is fixedly connected to the bottom of the second gear 204, a grinding wheel 2051 is fixedly connected to the outer surface of the first rotating rod 205, a second rotating rod 206 is fixedly connected to the bottom of the first gear 203, and a cutter 208 is fixedly connected to the surface of the second rotating rod 206.

[0024] When the first gear 203 rotates, its two sides mesh with the second gear 204, causing the two second gears 204 to rotate synchronously. The second gears 204 drive the first rotating rod 205 at the bottom to rotate, causing the grinding wheel 2051 on the first rotating rod 205 to rotate. At the same time, the first gear 203 directly drives the second rotating rod 206 to rotate, causing the cutter 208 on its surface to rotate. After the raw material is fed in, it is first cut and crushed by the high-speed rotating cutter 208. The crushed raw material falls into the lower part of the filter tank 301, where it is further refined by the grinding wheels 2051 rotating on both sides.

[0025] In a preferred embodiment, a fixing frame 402 is fixedly connected to the outer wall of the outer tub 4, and a drain pipe 401 is fixedly connected to the bottom of the outer tub 4.

[0026] When drainage is needed, open the drain pipe 401 at the bottom, and water can flow out of the device through the drain pipe 401.

[0027] In a preferred embodiment, the outer surface of the grinding wheel 2051 is provided with a plurality of protrusions, which are distributed in a spiral shape, and the cutting edge of the cutter 208 is serrated.

[0028] When the grinding wheel 2051 rotates, the spiral protrusions on its outer surface rotate with the grinding wheel 2051, which exerts a squeezing and kneading effect on the crushed raw material. The spiral structure pushes the raw material to move along the axial direction, so that the raw material is evenly contacted with the grinding wheel 2051, while promoting fiber separation. When the cutter 208 rotates, the serrated blade cuts the raw material through the sharpness of the serrated edge, increasing the contact area with the raw material and improving the cutting efficiency.

[0029] In a preferred embodiment, the inner wall of the rotating sleeve 207 is provided with a lubricating layer, and the rotating sleeve 207 and the second rotating rod 206 are connected by a bearing to achieve stable rotation of the second rotating rod 206 relative to the rotating sleeve 207.

[0030] The design of the bearings and lubrication layer greatly reduces the frictional resistance and wear between the second rotating rod 206 and the rotating sleeve 207, ensuring the smoothness of power transmission.

[0031] In a preferred embodiment, the diameter of the first gear 203 is smaller than the diameter of the second gear 204.

[0032] The diameter of the first gear 203 is smaller than that of the second gear 204. When the first gear 203 rotates, it drives the second gear 204 to rotate through gear meshing. Due to the diameter difference, the rotational speed of the second gear 204 is lower than that of the first gear 203, which increases the grinding torque and ensures more thorough fiber separation.

[0033] The foregoing description of an exemplary embodiment of a pulping apparatus for paper product raw materials provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
