Description

Technical Field

[0001] This utility model relates to the field of pulping and mixing tank technology, and in particular to a high-shear pulping and mixing tank mixing device. Background Technology

[0002] Pulping tank agitation refers to the process of mixing, dispersing, and transferring heat to materials in a pulping tank using a stirring device. The stirring device typically includes a stirring paddle or impeller. However, during the stirring process, the materials gradually become slurry, and the slurry has high viscosity, making it difficult to mix evenly and resulting in insufficient mixing.

[0003] In existing technologies, most mixing tanks are driven by a single shaft to rotate the mixing blades. This method makes it difficult to cut off materials that are stuck together, thus making it difficult to fully mix the materials and resulting in low production efficiency of the mixing tank. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-shear pulping tank mixing device to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A high-shear pulping kettle mixing device includes a pulping cylinder, a rotating plate inside the pulping cylinder, the rotating plate being rotatably mounted at the bottom of the pulping cylinder, a shearing cylinder at the top of the rotating plate, a rotating hole at the center of the rotating plate, a rotating shaft inserted into the rotating hole, a shearing plate fixedly mounted on the outer peripheral wall of the rotating shaft, a planetary gear set inside the pulping cylinder at the bottom of the rotating plate, a shearing structure at the upper end of the pulping cylinder, a bucket lid at the top of the pulping cylinder, and a drive shaft at the top of the bucket lid.

[0007] Furthermore, the shearing structure includes an undulating groove, which is formed on the inner wall of the pulping cylinder near the upper cylinder opening. Two guide rods are provided inside the undulating groove, and both guide rods are fixedly connected to the rotating shaft and are coaxially arranged.

[0008] Furthermore, a drive hole is provided at the top end of the rotating shaft, the drive hole is slidably engaged with the drive shaft, and a sealing plate is provided at the bottom end of the drive shaft.

[0009] Furthermore, the shearing plates are provided in multiples, and the spacing between adjacent shearing plates is equal. A pressure plate is provided at the bottom end of the shearing plates, and the outer peripheral wall of the pressure plate is in contact with the inner wall of the shearing cylinder.

[0010] Furthermore, a drive motor is provided at the top of the bucket lid, and a reducer is provided at the side end of the drive motor. The motor shaft of the drive motor is fixedly connected to the input end of the reducer, and the output end of the reducer is fixedly connected to the drive shaft.

[0011] Furthermore, a discharge pipe is provided on the side wall of the pulping cylinder.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. The high-shear pulping kettle mixing equipment, when the material enters the inside of the pulping cylinder and the shear plate rotates, the material located outside the shear cylinder will follow the rotation of the shear plate and enter the inside of the shear cylinder through the through groove on the surface of the shear cylinder. During the process of the material passing through the through groove, the shear plate and the groove wall can effectively cut the material, thereby effectively cutting off the mutually sticky materials, so as to improve the production efficiency of the pulping kettle.

[0014] 2. In this high-shear pulping kettle mixing equipment, when the rotating shaft rotates, the planetary gear set drives the rotating plate to rotate synchronously and in opposite directions, thereby causing the shearing cylinder and the shearing plate to rotate relative to each other, so as to improve the shearing efficiency;

[0015] 3. This high-shear pulping and mixing equipment, through the setting of undulating grooves, when the rotating shaft rotates, drives two guide rods to slide inside the undulating grooves, thereby causing the rotating shaft to float up and down through the undulating grooves. At this time, the shear plate fixedly connected to the rotating shaft will follow the up and down movement. Since the shear plate is always in a rotating state, the cutting angle between the shear plate and the through groove will fluctuate up and down to expand the cutting area and further improve the shearing efficiency.

[0016] 4. This high-shear pulping and mixing equipment, through the setting of the pressure plate, when the shear plate moves up and down with the rotating shaft, squeezes the material through the pressure plate, pushing the material at the bottom upward, so that the material can quickly pass through the through groove on the surface of the shear cylinder, thereby increasing the material movement speed and thus improving the mixing efficiency of the material.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 6 This utility model discloses a high-shear pulping kettle mixing device, including a pulping cylinder 1, a rotating plate 2 inside the pulping cylinder 1, the rotating plate 2 being rotatably disposed at the bottom of the pulping cylinder 1, a shearing cylinder 3 being disposed at the top of the rotating plate 2, a rotating hole 4 being opened at the center of the rotating plate 2, a rotating shaft 5 being inserted into the rotating hole 4, a shearing plate 6 being fixedly disposed on the outer peripheral wall of the rotating shaft 5, a planetary gear set 7 being disposed inside the pulping cylinder 1 and at the bottom of the rotating plate 2, a shearing structure 8 being disposed at the upper end of the pulping cylinder 1, a bucket cover 9 being disposed at the top of the pulping cylinder 1, and a drive shaft 10 being disposed at the top of the bucket cover 9.

[0028] In this embodiment, when in use, the bucket lid 9 is opened and the material to be pulped is poured into the pulping cylinder 1. The bucket lid 9 is then closed and the drive shaft 10 is inserted into the rotating shaft 5. The drive shaft 10 drives the rotating shaft 5 to rotate, causing the shearing plate 6 on the outer peripheral wall of the rotating shaft 5 to push the material to rotate. This, in conjunction with the slots on the surface of the shearing cylinder 3, cuts the material to achieve the purpose of separating the material.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, when the material enters the inside of the pulping cylinder 1 and the shearing plate 6 rotates, the material located outside the shearing cylinder 3 will follow the rotation of the shearing plate 6 and enter the inside of the shearing cylinder 3 through the through groove on the surface of the shearing cylinder 3. During the process of the material passing through the through groove, the shearing plate 6, together with the groove wall, can effectively cut the material, thereby effectively cutting off the mutually sticky materials and improving the production efficiency of the pulping kettle.

[0030] By setting up the planetary gear set 7, the rotation direction of the shearing cylinder 3 and the shearing plate 6 is opposite, thereby improving the shearing efficiency.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, the sun gear of the planetary gear set 7 is slidably connected to the rotating shaft 5, and the rotating shaft can slide up and down inside the sun gear. The internal gear ring of the planetary gear set 7 is fixedly connected to the rotating plate 2, and the planetary gears are rotatably connected to the bottom wall of the pulping cylinder 1 through the shaft. Therefore, when the rotating shaft 5 rotates, the rotating plate 2 can be driven to rotate synchronously and in opposite directions through the planetary gear set 7, thereby causing the shearing cylinder 3 and the shearing plate 6 to rotate relative to each other, so as to improve the shearing efficiency.

[0032] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 5 As shown, the shearing structure 8 includes an undulating groove 81, which is opened on the inner wall of the pulping cylinder 1 near the upper cylinder opening. Two guide rods 82 are arranged inside the undulating groove 81. Both guide rods 82 are fixedly connected to the rotating shaft 5 and are coaxially arranged.

[0033] In this embodiment, as Figure 3 The schematic diagram of the shearing structure 8 shown illustrates that, through the setting of the undulating groove 81, when the rotating shaft 5 rotates, it drives the two guide rods 82 to slide inside the undulating groove 81, thereby causing the rotating shaft 5 to float up and down through the undulating groove 81. At this time, the shearing plate 6, which is fixedly connected to the rotating shaft 5, will follow and undulate up and down. Since the shearing plate 6 is always in a rotating state, the cutting angle between the shearing plate 6 and the through groove (i.e., the position where the shearing plate 6 and the through groove of the shearing cylinder 3 intersect) will fluctuate up and down to expand the cutting area and further improve the shearing efficiency.

[0034] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the top end of the rotating shaft 5 is provided with a drive hole 11, which is slidably engaged with the drive shaft 10, and the bottom end of the drive shaft 10 is provided with a sealing plate.

[0035] In this embodiment, the drive hole 11 is used to install the drive shaft 10, so that the drive shaft 10 can drive the rotating shaft 5 to rotate when it rotates. When the drive shaft 10 is installed, the sealing plate can cooperate with the drive shaft 10 to compress the air inside the drive hole 11, so that the high-pressure air can push the rotating shaft 5 to move downward, so that the rotating shaft 5 can cooperate with the undulating groove 81 to move up and down.

[0036] In a further preferred embodiment of this utility model, such as Figure 4 and Figure 6 As shown, there are multiple shear plates 6, and the spacing between adjacent shear plates 6 is equal. A pressure plate 12 is provided at the bottom of the shear plates 6. The outer peripheral wall of the pressure plate 12 is in contact with the inner wall of the shear cylinder 3.

[0037] In this embodiment, by setting the pressure plate 12, when the shearing plate 6 moves up and down with the rotating shaft 5, the pressure plate 12 squeezes the material, pushing the material at the bottom upward, so that the material can quickly pass through the through groove on the surface of the shearing cylinder 3, thereby increasing the speed of material movement and thus improving the mixing efficiency of the material.

[0038] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a drive motor 13 is provided at the top of the bucket lid 9, and a reducer 14 is provided at the side end of the drive motor 13. The motor shaft of the drive motor 13 is fixedly connected to the input end of the reducer 14, and the output end of the reducer 14 is fixedly connected to the drive shaft 10.

[0039] In this embodiment, the drive motor 13, in conjunction with the reducer 14, is used to drive the drive shaft 10 to rotate, thereby achieving the purpose of driving the rotating shaft 5 to rotate.

[0040] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the side wall of the pulping cylinder 1 is provided with a discharge pipe 15.

[0041] In this embodiment, the material inside the pulping cylinder 1 is easily discharged through the discharge pipe 15.

[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
