Abstract
Description
Technical Field
[0001] This utility model relates to the field of papermaking technology, specifically to a device for synthesizing a bactericide for papermaking. Background Technology
[0002] Papermaking bactericides are chemical preparations used to control the growth of microorganisms during the papermaking process. Their core function is to prevent microorganisms from negatively impacting paper quality, equipment operation, and the production environment. By killing or inhibiting microorganisms such as bacteria, fungi, and algae, they ensure the smooth progress of the papermaking process and the quality of the final product. Traditional bactericide synthesis devices generally suffer from low mixing efficiency and incomplete reaction, mainly due to the limitations of a single stirring method and mechanical transmission structure. Existing technologies mostly adopt a single-shaft vertical stirring design, with the stirring blades fixed to a single rotating shaft. The material in the tank only moves in a circular motion with the stirring shaft, resulting in a large difference in the flow field between the central and peripheral areas, making it difficult to form effective convection.
[0003] Therefore, it is necessary to propose a device for synthesizing bactericides for papermaking to solve the above problems. Utility Model Content
[0004] Technical problem to be solved: The purpose of this utility model is to provide a papermaking bactericide synthesis device to solve the problems of low mixing efficiency and insufficient reaction that are common in existing bactericide synthesis devices mentioned in the background art.
[0005] Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution: A papermaking bactericide synthesis device, comprising a synthesis tank and a stirring assembly, wherein the stirring assembly comprises a drive motor fixedly installed on the top of the synthesis tank and a drive box concentrically fixedly installed inside the synthesis tank, wherein an internal gear ring is fixedly fitted inside the drive box, and a countersunk hole penetrating the bottom of the drive box is provided, wherein a baffle plate is movably fitted inside the countersunk hole; a drive shaft is concentrically provided inside the drive box, the upper end of the drive shaft is connected to the drive motor, a connecting plate is fixedly installed in the middle, and the lower end is fixedly connected to the baffle plate; two rotating shafts I are symmetrically provided on both sides of the drive shaft, the upper ends of the two rotating shafts I are rotatably connected to the connecting plate through bearings, gears are fixedly fitted in the middle, and the lower ends of the two shafts I penetrate the baffle plate and extend to the bottom of the synthesis tank, and the two gears mesh with the internal gear ring for transmission; a horizontal plate is fixedly installed on the rotating shaft I below the drive box, and a rotating shaft II is fixedly installed at the bottom of the other end of the horizontal plate, and stirring blades are evenly fixedly installed along the circumference on both rotating shafts I and rotating shaft II.
[0006] Preferably, the synthesis tank includes a tank body, with a feed inlet and a water inlet at the top, and a discharge pipe fixedly installed at the bottom that communicates with the interior of the tank. The discharge pipe is equipped with a valve, and a sealing cap is hinged to the feed inlet of the synthesis tank.
[0007] Preferably, the baffle plate has two symmetrical through holes, and the two rotating shafts I extend to the bottom of the synthesis tank through the corresponding through holes, and a sealing ring is provided between the rotating shaft I and the through hole.
[0008] Preferably, a reducer is fixedly installed on the top of the synthesis tank, the drive shaft is connected to the drive motor via the reducer, and multiple connecting rods are evenly fixedly installed on the circumference of the drive box, with the other end of each connecting rod fixedly connected to the tank body.
[0009] Preferably, the minimum distance between the rotating shaft II and the inner wall of the tank is a, the distance between the rotating shaft I and the rotating shaft II fixed thereon is b, the distance between the two rotating shafts I is c, and the width of the stirring blade is d, wherein a > d, b > 2d, c > b, and cb > 2d.
[0010] Preferably, both rotating shaft I and rotating shaft II have three stirring blades, and one of the stirring blades on rotating shaft II is located on the water-facing side of rotating shaft II and is tangent to the movement trajectory of rotating shaft II.
[0011] Preferably, in the initial state, the centerlines of the two rotating shafts I and the two rotating shafts II are located in the same plane, and the rotating shafts I and II are alternately arranged.
[0012] Beneficial effects: Compared with the prior art, this utility model provides a papermaking bactericide synthesis device. This papermaking bactericide synthesis device has a unique structure and is easy to use. The drive motor drives the drive shaft to rotate through the reducer. The drive shaft synchronously drives the connecting plate and the baffle plate to rotate. At this time, the symmetrically arranged rotating shaft I, supported by the bearing of the connecting plate, not only revolves with the drive shaft, but also rotates on its own axis through the meshing of the gear and the internal gear ring. The rotating shaft I drives the rotating shaft II to revolve synchronously through the cross plate. Since the angular velocities of the two are the same but there is a radial displacement in the installation position, a speed difference is formed between the rotating shaft II and the rotating shaft I. When the rotating shaft II enters the gap area of the adjacent rotating shaft I, its movement direction is opposite to that of the other rotating shaft I, which causes the liquid in this area to generate convection and collision. At the same time, the tangential stirring blades set on the water-facing side of the rotating shaft II can effectively separate water and reduce rotational resistance.
[0013] This device creates a three-dimensional stirring effect through the revolution and rotation of rotating shaft I and the differential motion of rotating shaft II, generating turbulence from the center to the edge of the tank, thus solving the dead zone problem of traditional single-shaft stirring. In addition, the counter-movement of rotating shaft II and the adjacent rotating shaft I generates shear force, which promotes the rapid exchange of materials in different concentration areas, making it particularly suitable for the uniform synthesis of multi-component bactericides.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Example 1: This Example 1 provides a papermaking bactericide synthesis apparatus with a unique structure. Please refer to [link / reference]. Figure 1-4 As shown, the system includes a synthesis tank 1, which includes a tank body 11. The top of the tank body 11 has a feed inlet and a water inlet 13, and the bottom is fixedly installed with a discharge pipe 14 communicating with the interior of the tank body 14. The discharge pipe 14 is equipped with a valve. The feed inlet of the synthesis tank 1 is hinged with a sealing cover 12. The water inlet 13 is connected to a municipal water pipe. The system also includes a stirring assembly 2, which includes a drive motor 21 fixedly installed on the top of the synthesis tank 1 and a drive box 22 concentrically fixedly installed inside the synthesis tank 1. The drive motor 21 is electrically connected to an external power source. An internal gear ring 23 is fixedly fitted inside the drive box 22. The bottom of the drive box 22 has a countersunk hole communicating with the interior of the drive box 22. A baffle plate 28 is movably fitted inside the countersunk hole.
[0021] Inside the drive box 22, a drive shaft 24 is concentrically arranged. The upper end of the drive shaft 24 is connected to the drive motor 21, the middle part is fixedly installed with a connecting plate 25, and the lower end is fixedly connected to the baffle plate 28. A reducer is fixedly installed on the top of the synthesis tank 1. The top of the drive box 22 has a through hole for the drive shaft 24 to pass through. The top end of the drive shaft 24 passes through the synthesis tank 1 and is connected to the drive motor 21 via the reducer. Multiple connecting rods 212 are evenly fixedly installed around the circumference of the drive box 22. The other end of each connecting rod 212 is fixedly connected to the tank body 11. The reducer can not only increase the torque of the drive shaft 24, but also protect the drive motor 21.
[0022] Two rotating shafts I26 are symmetrically arranged on both sides of the drive shaft 24. The upper ends of the two rotating shafts I26 are rotatably connected to the connecting plate 25 through bearings. Gears 27 are fixedly mounted in the middle. The lower ends of the two rotating shafts I26 pass through the baffle plate 28 and extend to the bottom of the synthesis tank 1. The two gears 27 mesh with the internal gear ring 23 for transmission. Two through holes are symmetrically opened on the baffle plate 28. The two rotating shafts I26 extend to the bottom of the synthesis tank 1 through the corresponding through holes. A sealing ring is provided between the rotating shafts I26 and the through holes. The baffle plate 28 and the sealing ring can prevent the bactericide from entering the drive box 22 during stirring, which would cause the internal gear ring 23 and the gears 27 to corrode and rust.
[0023] A horizontal plate 29 is fixedly installed on the rotating shaft I 26 below the drive box 22. A rotating shaft II 210 is fixedly installed at the bottom of the other end of the horizontal plate 29. Stirring blades 211 are evenly fixedly installed on both rotating shaft I 26 and rotating shaft II 210 along the circumference. In the initial state, the center lines of the two rotating shafts I 26 and the two rotating shafts II 210 are located in the same plane, and rotating shafts I 26 and rotating shaft II 210 are alternately arranged so that the two rotating shafts II 210 alternately enter the area between the two rotating shafts I 26 to avoid motion interference. The minimum distance between rotating shaft II 210 and the inner wall of tank 11 is a, the distance between rotating shaft I 26 and rotating shaft II 210 fixed on it is b, the distance between the two rotating shafts I 26 is c, and the width of stirring blade 211 is d, where a > d, b > 2d, c > b, and cb > 2d.
[0024] Working principle: When using this device to synthesize a bactericide, the raw materials are first poured into the synthesis tank 1 through the feed inlet. Then, an appropriate amount of water is added according to the ratio. The drive motor 21 is started, and the drive motor 21 drives the drive shaft 24 to rotate through the reducer. After the drive shaft 24 rotates, it drives the connecting plate 25 and the baffle plate 28 to rotate. This causes the rotating shaft I 26 to rotate along the drive shaft 24 and also rotate on its own axis through the meshing of the internal gear ring 23 and the gear 27. When the rotating shaft I 26 rotates, it drives the rotating shaft II 210 to rotate along the rotating shaft I 26 through the horizontal plate 29. Since the angular velocities of the rotating shaft I 26 and the rotating shaft II 210 are the same, there is a speed difference between the rotating shaft I 26 and the rotating shaft II 210. When one of the rotating shafts II 210 enters between the two rotating shafts I 26, the rotating shaft II 210 will move in the opposite direction to the other rotating shaft I 26, thereby causing the liquid in the area between the two rotating shafts I 26 to collide and mix, thus making the bactericide mixture more uniform.
[0025] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 3As shown, there are three stirring blades 211 on both rotating shaft I 26 and rotating shaft II 210. One of the stirring blades 211 on rotating shaft II 210 is located on the water-facing side of rotating shaft II 210 and is tangent to the movement trajectory of rotating shaft II 210. With this design, the stirring blade 211 on the water-facing side can separate the liquid, thereby improving the water separation performance of rotating shaft II 210 and reducing the resistance encountered by rotating shaft II 210 when rotating.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
