Description

Technical Field

[0001] This application relates to the field of agitator technology, and in particular to a multi-angle agitator for impregnation tanks. Background Technology

[0002] An impregnation tank is a device used to permeate liquids into solid materials. Through processes such as vacuum and pressurization, the liquid is fully immersed in the material to achieve specific treatment effects. It is widely used in industries such as wood processing, food, and pharmaceuticals. Impregnation tanks are equipped with agitators to stir and mix the materials and impregnation solution inside the tank, accelerating the impregnation process. A search revealed that patent document CN222550170U discloses an impregnation tank with a stirring function, comprising an impregnation tank body, a tank lid, tank legs, a discharge pipe, and a connecting column. An opening mechanism is provided between the impregnation tank body and the tank lid. The inner cavity of the impregnation tank contains a stirring mechanism and a funnel mechanism. The connecting column contains a telescopic mechanism, a transmission mechanism, and a plug-in mechanism. By incorporating these mechanisms, medicinal materials are placed in the funnel basket. The stirring mechanism is activated, causing the lead screw to rotate via the plug-in mechanism, driving the funnel basket downwards. The lid is closed via the opening mechanism, causing the lid to press against the cylinder, which in turn moves the lead screw downwards. The lead screw then moves the telescopic mechanism downwards, and the telescopic mechanism, through the transmission mechanism, moves the plug-in mechanism upwards, separating the plug-in mechanism. A second motor is then activated, causing the stirring mechanism to rotate and stir. The stirring mechanism prevents the lead screw from rotating, thus achieving the impregnation of the medicinal materials.

[0003] The above-mentioned solution still has at least the following shortcomings in actual use: During the soaking process of medicinal materials, the structure can only achieve stirring in one direction by simply rotating the stirring rod horizontally. The diagonal area and bottom corner of the tank are prone to forming flow blind zones. In addition, the distance between the stirring rod and the tank wall is fixed, and the material near the tank wall is prone to stagnation due to the weakening of stirring force. It is impossible to achieve uniform mixing throughout the entire tank, resulting in uneven soaking of materials, relatively long soaking time, and low soaking efficiency.

[0004] Therefore, we propose a multi-angle stirrer for impregnation tanks to solve the above problems. Utility Model Content

The worm gear is fixedly installed at the bottom of the upper vertical shaft, and the lower vertical shaft is fixedly installed at the bottom of the worm gear. The bottom of the lower vertical shaft extends to the outside of the hollow vertical cylinder. Multiple horizontal stirring rods are fixedly installed at the bottom of the lower vertical shaft and are distributed in a ring at equal intervals. Multiple stirring blades are fixedly installed on multiple horizontal stirring rods and are evenly distributed. The drive assembly is located on the top of the tank cover. The drive assembly is used to control the hollow vertical cylinder and the upper vertical shaft to rotate in opposite directions at the same time. The multi-angle stirring assembly is located on the hollow vertical cylinder.

[0007] A further configuration of this application is as follows: the drive assembly includes a first bevel gear, a second bevel gear, a motor, and a third bevel gear. The first bevel gear is fixedly sleeved on the top end of the hollow vertical cylinder, the second bevel gear is fixedly installed on the top end of the upper vertical shaft, the motor is fixedly installed on the top of the can lid, and the third bevel gear is fixedly installed on the output shaft end of the motor.

[0008] A further configuration of this application is as follows: the multi-angle stirring assembly includes a rotating shaft, a worm gear, two spur gears, four horizontal stirring rods, multiple vertical stirring rods, and four spur gears. The rotating shaft is rotatably installed inside the hollow vertical cylinder and located in front of the worm gear. The worm gear is fixedly sleeved on the rotating shaft, and the worm gear meshes with the worm gear. Both spur gears are fixedly sleeved on the rotating shaft, and the two spur gears are symmetrically distributed on the left and right sides of the worm gear. Two of the four horizontal stirring rods are rotatably installed on the left side of the hollow vertical cylinder, and the other two horizontal stirring rods are rotatably installed on the right side of the hollow vertical cylinder. The four horizontal stirring rods are arranged symmetrically in pairs, and one end of each of the four horizontal stirring rods extends into the hollow vertical cylinder. The multiple vertical stirring rods are fixedly installed on the four horizontal stirring rods and are evenly distributed. The four spur gears are respectively fixedly installed on the corresponding end of the horizontal stirring rod located inside the hollow vertical cylinder, and the four spur gears mesh with the corresponding spur gears.

[0009] A further feature of this application is that the vertical stirring rods on the two horizontal stirring rods located on the same side are arranged in an alternating pattern.

[0010] A further feature of this application is that: round holes are provided on both the left and right sides of the hollow vertical cylinder, and sealed bearings are fixedly fitted on each of the four horizontal stirring rods, with the outer rings of the four sealed bearings respectively fixedly connected to the inner walls of the corresponding round holes.

It can also control the multiple horizontal stirring rods and multiple stirring blades to rotate synchronously horizontally, forming radial cutting and stirring of the bottom area in the impregnation tank, thoroughly mixing the material accumulated at the bottom with the impregnation liquid, avoiding local sedimentation. It can also control the four horizontal stirring rods to rotate simultaneously, and make the two horizontal stirring rods on the same side rotate in opposite directions, forming a longitudinal cutting flow. This enables multi-angle stirring and mixing of the impregnation liquid and the material, increasing the movement range and speed of the impregnation liquid and the material, which can aggravate the turbulence effect of the impregnation liquid in the impregnation tank, increase the movement range of the impregnation liquid and the material, shorten the material impregnation time, and improve the overall impregnation efficiency.

[0023] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] See Figures 1-5 This application provides a multi-angle stirrer for an impregnation tank, including an impregnation tank 1, a tank cover 2, and a stirrer mechanism disposed on the tank cover 2. The tank cover 2 is fixed to the top of the impregnation tank 1 by bolts, and the use of bolts to fix the tank cover 2 facilitates the installation and removal of the tank cover 2. The stirrer mechanism includes a hollow vertical cylinder 3, an upper vertical shaft 4, a worm gear 5, a lower vertical shaft 6, multiple horizontal stirring rods 7, multiple stirring blades 8, a drive assembly, and a multi-angle stirring assembly 13. A hollow vertical cylinder 3 is rotatably mounted on a tank cover 2, with its bottom end penetrating the tank cover 2. An upper vertical shaft 4 is rotatably mounted on the inner top wall of the hollow vertical cylinder 3, with its top end extending to the outside of the hollow vertical cylinder 3. A worm gear 5 is fixedly mounted on the bottom end of the upper vertical shaft 4, and a lower vertical shaft 6 is fixedly mounted on the bottom end of the worm gear 5, with its bottom end extending to the outside of the hollow vertical cylinder 3. Multiple horizontal stirring rods 7 are fixedly mounted on the bottom end of the lower vertical shaft 6 and are distributed in a ring at equal intervals. Multiple stirring blades 8 are fixedly mounted on multiple horizontal stirring rods 7 and are evenly distributed. By utilizing the synergistic effect of multiple horizontal stirring rods 7 and multiple stirring blades 8, the bottom area inside the impregnation tank can be radially rotated and stirred, enhancing the impregnation effect of the material.

[0025] In this embodiment, the drive assembly is located on the top of the can lid 2. The drive assembly is used to control the hollow vertical cylinder 3 and the upper vertical shaft 4 to rotate simultaneously in opposite directions. The drive assembly includes a first bevel gear 9, a second bevel gear 10, a motor 11, and a third bevel gear 12. The first bevel gear 9 is fixedly sleeved on the top of the hollow vertical cylinder 3, the second bevel gear 10 is fixedly installed on the top of the upper vertical shaft 4, the motor 11 is fixedly installed on the top of the can lid 2, and the third bevel gear 12 is fixedly installed on the output shaft end of the motor 11. Both the first bevel gear 9 and the second bevel gear 10 mesh with the third bevel gear 12, and the motor 11 can control the rotation of the third bevel gear 12. By utilizing the meshing transmission action of the first bevel gear 9 and the second bevel gear 10 with the third bevel gear 12, the hollow vertical cylinder 3 and the upper vertical shaft 4 can be controlled to rotate synchronously in opposite directions, so that the worm gear 5 and the lower vertical shaft 6 rotate synchronously with the upper vertical shaft 4. The wiring connection method and control method of the motor 11 are mature technologies in the field and have been fully disclosed and described, so they will not be described again in this document.

[0026] In this embodiment, the multi-angle stirring assembly 13 is disposed on the hollow vertical cylinder 3. The multi-angle stirring assembly 13 includes a rotating shaft 131, a worm gear 132, two spur gears 133, four horizontal stirring rods 134, multiple vertical stirring rods 135, and four spur gears 136. The rotating shaft 131 is rotatably mounted inside the hollow vertical cylinder 3 and located in front of the worm 5. The worm gear 132 is fixedly sleeved on the rotating shaft 131, and the worm 5 meshes with the worm gear 132. Both spur gears 133 are fixedly sleeved on the rotating shaft 131, and the two spur gears 136... Wheel 133 is symmetrically distributed on the left and right sides of worm gear 132. Two of the four horizontal stirring rods 134 are rotatably mounted on the left side of hollow vertical cylinder 3, and the other two are rotatably mounted on the right side of hollow vertical cylinder 3. The four horizontal stirring rods 134 are arranged symmetrically in pairs, and one end of each of the four horizontal stirring rods 134 extends into hollow vertical cylinder 3. Multiple vertical stirring rods 135 are fixedly mounted on the four horizontal stirring rods 134 and are evenly distributed. Each of the four spur gears 136 is fixedly installed at one end of the corresponding horizontal stirring rod 134 located inside the hollow vertical cylinder 3. The four spur gears 136 mesh with their corresponding spur gears 133. Utilizing the meshing transmission action of the worm gear 5 and worm wheel 132, the rotation of the rotating shaft 131 can be controlled, causing the two spur gears 133 to rotate simultaneously with the rotating shaft 131. Furthermore, utilizing the meshing transmission action of the four spur gears 136 with their corresponding spur gears 133, the simultaneous rotation of the four horizontal stirring rods 134 can be controlled, thus enabling the horizontal stirring rods to rotate simultaneously. The vertical stirring rod 135 on rod 2 134 rotates along with it, and the two horizontal stirring rods 2 134 on the same side rotate in opposite directions. Thus, under the state of the hollow vertical cylinder 3 driving the four horizontal stirring rods 2 134 to rotate horizontally, a radial cutting flow is formed. Combined with the rotation of the four horizontal stirring rods 2 134, a longitudinal cutting flow is formed. This can achieve multi-angle stirring and mixing of the impregnation liquid and the material, which can aggravate the turbulence effect of the impregnation liquid in the impregnation tank 1, increase the movement range of the impregnation liquid and the material, shorten the material impregnation time, and improve the overall impregnation efficiency.

[0027] In this embodiment, the vertical stirring rods 135 on the two horizontal stirring rods 134 on the same side are arranged in an alternating manner, which can ensure that the vertical stirring rods 135 on the same side will not collide with each other, thereby ensuring that the two vertical stirring rods 135 on the same side rotate smoothly.

[0028] In this embodiment, round holes are provided on both the left and right sides of the hollow vertical cylinder 3, and sealed bearings 137 are fixedly fitted on the four horizontal stirring rods 134. The outer rings of the four sealed bearings 137 are fixedly connected to the inner walls of the corresponding round holes. The design of the sealed bearings 137 can ensure the stability and smoothness of the horizontal stirring rods 134 when rotating, and can also prevent the impregnation liquid from entering the interior of the hollow vertical cylinder 3.

[0029] In this embodiment, a feed hopper 14 is fixedly installed on the top of the tank cover 2, and the bottom end of the feed hopper 14 penetrates the tank cover 2. The feed hopper 14 is designed to facilitate the addition of impregnation liquid and materials into the impregnation tank 1 without disassembling the tank cover 2, thus reducing the number of operation steps. A baffle 15 is slidably installed on the top of the feed hopper 14, and a handle is fixedly installed on the top of the baffle 15. The baffle 15 is designed to seal the top opening of the feed hopper 14. It should be noted that a drain pipe is fixedly installed on the bottom side of the impregnation tank 1, and a drain valve is installed on the drain pipe to facilitate the discharge of the impregnation liquid. This is a conventional technical means in the existing technical field, so it is not described in detail in this article.

[0030] In this embodiment, lifting rings 16 are fixedly installed on both the left and right sides of the top of the tank cover 2. The design of the lifting rings 16 makes it easy to use lifting equipment such as winches to lift the tank cover 2 and the agitator mechanism to a certain height, so as to facilitate the removal of the soaked material. It also makes it easier to inspect, clean or replace the agitator mechanism and the inside of the soaking tank 1 in the later stage, thus improving the convenience of equipment maintenance.

[0031] With the above structure, the working principle of the multi-angle stirrer for impregnation tanks provided in this application is as follows: Open the cover 15, pour the appropriate amount of impregnation liquid and material into the impregnation tank 1 from the feed hopper 14 in sequence, and then put the cover 15 back on the top of the feed hopper 14. The material is immersed in the impregnation liquid, and the material impregnation treatment can be carried out. During the impregnation process, the control motor 11 operates, and the output shaft of the motor 11 drives the bevel gear 12 to rotate. Under the meshing transmission action of the bevel gears 9 and 10, the hollow vertical cylinder 3 and the upper vertical shaft 4 can be controlled to rotate synchronously in opposite directions. At the same time, the upper vertical shaft 4 drives the worm gear 5 and the lower vertical shaft 6 to rotate synchronously. When the hollow vertical cylinder 3 rotates, it drives the four horizontal stirring rods 134 and multiple vertical stirring rods 135 to rotate horizontally, forming a radial cutting flow, increasing the movement range and speed of the impregnation liquid and the material. When the lower vertical shaft 6 rotates, it drives multiple horizontal stirring rods 7 and multiple stirring blades 8 to rotate horizontally synchronously, forming radial cutting and stirring of the bottom area in the impregnation tank 1, fully mixing the material accumulated at the bottom with the impregnation liquid, and avoiding local sedimentation. When the worm 5 rotates, under the meshing transmission action of the worm 5 and the worm wheel 132, the rotating shaft 131 can be controlled to drive the two spur gears 133 to rotate simultaneously. By utilizing the meshing transmission action of the four spur gears 136 with the corresponding spur gears 133, the four horizontal stirring rods 134 can be controlled to rotate simultaneously, so that the vertical stirring rods 135 on the horizontal stirring rods 134 follow the rotation, and the two horizontal stirring rods 134 on the same side rotate in opposite directions, forming a longitudinal cutting flow, which further increases the movement range and speed of the impregnation liquid and the material, thereby enabling multi-angle stirring and mixing of the impregnation liquid and the material. This can intensify the turbulence effect of the impregnation liquid in the impregnation tank 1, increase the movement range of the impregnation liquid and the material, shorten the material impregnation time, and improve the overall impregnation efficiency. After the material is impregnated, stop the motor 11, open the drain valve on the drain pipe to release the impregnation liquid. After all the impregnation liquid has been drained, unscrew the bolts on the tank cover 2, and use a winch or other lifting equipment to lift the tank cover 2 and the agitator mechanism to a certain height so that the agitator mechanism is completely lifted out of the impregnation tank 1. The impregnated material can then be taken out. Then, control the winch or other lifting equipment to run in the reverse direction to lift the tank cover 2 and the agitator mechanism back onto the impregnation tank 1. Finally, use bolts to fix the tank cover 2 onto the impregnation tank 1. Following the above operating steps, the next batch of material can be impregnated.
