Abstract
Description
Technical Field
[0001] This utility model relates to the field of papermaking production, specifically a pulping device for papermaking production. Background Technology
[0002] The papermaking process can be divided into major steps such as pulping, conditioning, papermaking, and processing. The pulping process is called refining, which imparts specific properties to the pulp to meet the requirements of making special types of paper. When using existing papermaking refining equipment, raw materials and water are generally introduced into the refining equipment at the same time, and then the raw materials are ground and mixed with water by the rotation of the grinding disc.
[0003] However, in existing pulping equipment, raw materials tend to accumulate during feeding, affecting the feeding process. Furthermore, continuous and large-volume feeding can lead to insufficient pulping on the pulping disc during the pulping operation, thus affecting the pulping effect. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a pulping device for papermaking, which solves the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pulping device for papermaking, comprising a pulping box; a pulping disc is rotatably mounted inside the pulping box via a rotating shaft; a pulping sleeve matching the pulping disc is fixedly installed at the bottom of the pulping box; a feed hood is fixedly installed at the top of the pulping box; a discharge plate is fixedly installed inside the feed hood; discharge ports are arranged in a circular array on the discharge plate; a rotating box is rotatably mounted on the rotating shaft; a cover plate is fixedly installed on the rotating box; the top of the cover plate is pointed, and the lower surface of the cover plate contacts the upper surface of the discharge plate.
[0006] Preferably, a motor housing is fixedly installed inside the feed hood by a fixing rod, a first motor is fixedly installed inside the motor housing, a gear is fixedly installed on the drive end of the motor, and a gear ring that meshes with the gear is fixedly installed on the inner wall of the rotating box.

[0008] Preferably, a feed hopper is fixedly connected to the top of the grinding box, and a discharge pipe is fixedly connected to the bottom of the grinding box, the discharge pipe being connected to the inside of the grinding sleeve.
[0009] Preferably, the discharge pipe is equipped with a valve.
[0010] Preferably, a water inlet pipe is fixedly connected to the top of the grinding tank.
[0011] Beneficial effects
[0012] This utility model provides a pulping device for papermaking, which has the following beneficial effects:
[0013] 1. The device is equipped with a refining box for refining. A refining disc and refining sleeve work together to grind the papermaking raw materials. A feed hood guides the flow of raw materials and provides ample space in the feed section, preventing direct entry between the refining disc and sleeve, thus avoiding material accumulation. A discharge plate with a discharge port allows raw materials entering the refining box to pass between the refining disc and sleeve. A cover plate partially covers the discharge port, allowing the remaining material to fall between the refining disc and sleeve for refining. The rotating cover plate prevents material from remaining on the discharge plate and also provides some agitation, effectively preventing insufficient refining and ensuring optimal refining results.
[0014] 2. The motor housing can protect the first motor. When the first motor is started, the rotation of the first motor drive end can drive the gear to rotate. The gear meshes with the gear ring, which in turn drives the gear ring to rotate, thereby driving the rotating box to rotate. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Wherein, directional terms such as "upper" and "lower" mentioned herein are used in conjunction with... Figure 1 The orientation is used as a reference.
[0020] Please see Figure 1-3This utility model provides a technical solution: a pulping device for papermaking production, including a pulping box 1; a pulping disc 3 is rotatably installed inside the pulping box 1 via a rotating shaft, a pulping sleeve 17 matching the pulping disc 3 is fixedly installed at the bottom of the pulping box 1, a feed hood 2 is fixedly installed at the top of the pulping box 1, a discharge plate 6 is fixedly installed inside the feed hood 2, a discharge port 10 is opened in a circular array on the discharge plate 6, a rotating box 4 is rotatably installed on the rotating shaft, a cover plate 5 is fixedly installed on the rotating box 4, the top of the cover plate 5 is pointed, and the lower surface of the cover plate 5 is in contact with the upper surface of the discharge plate 6.
[0021] The pulping chamber 1 is installed, allowing pulping to take place within it. A pulping disc 3 and a pulping sleeve 17 are installed, working together to grind the papermaking raw materials. A feed hood 2 guides the flow of the raw materials and provides a larger feed space, preventing the raw materials from directly entering between the pulping disc 3 and the pulping sleeve 17, thus effectively avoiding material accumulation. A discharge plate 6 with a discharge port 10 allows the paper to pass through... The raw material entering the grinding chamber 1 can enter between the grinding disc 3 and the grinding sleeve 17 through the feed port 10. By installing a cover plate 5, part of the feed port 10 can be covered, allowing the raw material to fall through the remaining feed port 10 between the grinding disc 3 and the grinding sleeve 17 for grinding. Furthermore, by setting the cover plate 5 to be rotated, it can prevent the raw material from remaining on the feed plate 6 and also play a certain role in stirring. This can effectively avoid continuous large-scale feeding, which would lead to insufficient grinding of the grinding disc 3 and affect the grinding effect.
[0022] Furthermore, a motor housing 16 is fixedly installed inside the feed hood 2 by a fixing rod. A first motor 7 is fixedly installed inside the motor housing 16. A gear 8 is fixedly installed on the motor drive end. A gear ring 9 that meshes with the gear 8 is fixedly installed on the inner wall of the rotating box 4.
[0023] The motor housing 16 can protect the first motor 7. When the first motor 7 is started, the rotation of the first motor 7 drive end can drive the gear 8 to rotate. The gear 8 meshes with the gear ring 9, which can drive the gear ring 9 to rotate, thereby driving the rotating box 4 to rotate.
[0024] Furthermore, a second motor 11 for driving the rotating shaft is fixedly installed on the top of the grinding box 1.
[0025] The second motor 11 is installed. When the second motor 11 is started, the drive end of the second motor 11 rotates, which can drive the rotating shaft to rotate.
[0026] Furthermore, a feed hopper 12 is fixedly connected to the top of the grinding box 1, and a discharge pipe 14 is fixedly connected to the bottom of the grinding box 1. The discharge pipe 14 is connected to the inside of the grinding sleeve 17.
[0027] By installing a feed hopper 12, papermaking raw materials can be fed into the pulping box 1 for processing. By connecting a discharge pipe 14, the pulped raw materials in the pulping box 1 can be discharged through the discharge pipe 14.
[0028] Furthermore, a valve 15 is installed on the discharge pipe 14.
[0029] The discharge rate of slurry can be controlled by opening and closing valve 15.
[0030] Furthermore, a water inlet pipe 13 is fixedly connected to the top of the grinding box 1.
[0031] By providing a water inlet pipe 13, the water used for grinding can be introduced into the grinding box 1 through the water inlet pipe 13.
[0032] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0033] The working principle and usage process of this utility model are as follows: When in use, the raw material is fed into the pulping box 1 from the feed hopper 12. Under its own weight, the raw material falls onto the feed plate 6 and the cover plate 5. The raw material falling onto the cover plate 5 falls along the cover plate 5 onto the feed plate 6. At the same time as the raw material is fed in, water is fed into the pulping box 1. The first motor 7 is started to drive the gear 8 to rotate. The gear 8 meshes with the gear ring 9 to drive the gear ring 9 to rotate, which in turn drives the rotating box 4 to rotate, thereby driving the cover plate 5 to rotate. Water and raw material fall through the feed port 10 into the space between the pulping disc 3 and the pulping sleeve 17. The second motor 11 is started. The drive end of the second motor 11 rotates to drive the rotating shaft and the pulping disc 3 to rotate, thereby grinding the raw material. The valve 15 is opened to discharge the ground pulp through the discharge pipe 14.
