Description

Technical Field

[0001] This utility model belongs to the technical field of degassing devices, specifically relating to a high-efficiency degassing machine with uniform feeding. Background Technology

[0002] A defoamer is a device that removes air bubbles from a stirred liquid slurry. It is widely used in the food and chemical industries for defoaming liquid slurries containing air bubbles. Current slurry defoaming methods generally employ either chemical methods (adding defoamers) or physical methods (vacuum stirring). Chemical methods require the addition of defoamers, some of which may adversely react with the raw materials. Vacuum stirring defoaming involves placing a certain amount of slurry in a sealed container and using a drive device to rotate a defoaming disc at high speed while simultaneously stirring and using a vacuum pump to create a vacuum, thus achieving defoaming. This method is physical and generally does not alter the physicochemical properties of the material. However, traditional equipment places the feed inlet on one side of the defoamer tank, resulting in uneven feed distribution. This makes it impossible to control the thickness of the slurry on the defoaming disc. Uneven slurry thickness prevents tiny air bubbles from being exposed, thus preventing complete elimination of air bubbles and affecting the quality of the slurry, ultimately impacting the quality of the resulting lithium batteries.

[0003] Degassing discs are mainly used in the transmission components of degassing machines. They are an important component for degassing machines to achieve the degassing function. Currently, most commonly used degassing discs are conical discs with a certain angle, which means that the cutting force in the tangential direction of the degassing disc under centrifugal force cannot be fully utilized, resulting in an insufficient degassing effect.

[0004] On the other hand, the equipment must be stopped during material feeding and degassing, which takes a long time and greatly reduces the degassing efficiency of the device. Therefore, there is an urgent need to develop a high-efficiency degassing machine that can produce uniform feed, prevent material accumulation, achieve good degassing effect, and does not require stopping during feeding and degassing. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology, such as uneven feeding leading to poor degassing effect and easy accumulation of material causing incomplete degassing. It provides a high-efficiency degassing machine that discharges material from multiple outlets, has uniform discharge, facilitates degassing, has high degassing efficiency, and has a good degassing effect.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a high-efficiency degassing machine with uniform feeding, comprising: a tank;

[0007] A can lid is fitted onto the can body and is sealed to the can body.

[0008] A centrifugal spindle extends from the tank cover into the tank body, and a feeding chamber is provided at the center of the centrifugal spindle.

[0009] A drive assembly, mounted on the tank cover, is used to drive the centrifugal spindle to rotate;

[0010] A vacuum assembly is used to extract air and other gases from the tank.

[0011] The centrifugal spindle is equipped with m centrifugal components at its end, where m ≥ 1. The m centrifugal components are arranged sequentially on the centrifugal spindle, each centrifugal component including a centrifugal disc mounted on the centrifugal spindle, multiple discharge holes equidistantly arranged in a circumferential array on the centrifugal spindle, and a baffle mounted on the centrifugal spindle to limit the discharge height. The discharge holes are all connected to the feed chamber. The slurry enters the feed chamber from the feed port at the top of the centrifugal spindle and is thrown out from the discharge holes. The thrown slurry falls onto the centrifugal disc under the action of the baffle, and the slurry on the centrifugal disc is thrown outward under the action of centrifugal force, separating the air bubbles in the slurry. The vacuum component is used to evacuate and defoam the tank.

[0012] Furthermore, the drive assembly includes: a drive motor mounted on the can cover, a drive pulley coaxially connected to the output shaft of the drive motor, and a driven pulley connected to the drive pulley via a synchronous belt, the driven pulley being sleeved and mounted on the centrifugal main shaft.

[0013] Furthermore, the bottom end of the centrifugal spindle is sealed by a pressure cap.

[0014] Furthermore, the centrifuge disc is arranged in a disc shape, and the slurry moves on the centrifuge disc in a direction away from the centrifuge main axis. The centrifuge disc gradually thins from its center to its edge, forming a slope, which facilitates the movement of the slurry in a direction away from the centrifuge main axis.

[0015] Furthermore, the centrifugal spindle is rotatably connected to the tank lid via a bearing assembly.

[0016] Furthermore, in each centrifugal assembly, the baffle and the discharge port are located above the centrifugal disc, with the lowest end of the baffle close to the upper surface of the centrifugal disc.

[0017] Furthermore, m=2, and the two centrifugal components are mounted on the centrifugal spindle and positioned vertically.

[0018] The beneficial effects of this utility model of a high-efficiency degassing machine with uniform feeding are:

[0019] 1. This utility model feeds the slurry from the center of the centrifugal spindle, allowing it to exit evenly from multiple discharge holes at the end of the spindle. This ensures the slurry falls evenly onto the centrifugal disc, resulting in a uniform thickness of slurry on the disc. This facilitates degassing, effectively improves degassing efficiency and quality, and overcomes the defects of uneven discharge and uneven slurry thickness on the degassing disc found in existing equipment.

[0020] 2. The centrifugal disc of this utility model is disc-shaped and gradually thins from its center to its edge, so that the cutting force in the tangential direction of the degassing disc under the action of centrifugal force is maximized, which facilitates degassing. On the other hand, it can effectively solve the problem that the slurry is easy to accumulate on the degassing disc, resulting in incomplete degassing.

[0021] 3. The degassing machine of this utility model is set to be online, which can degas while feeding, without stopping the machine during feeding and discharging, thus greatly improving the degassing efficiency. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] like Figures 1-4The present invention provides a specific embodiment of a high-efficiency degassing machine with uniform feeding, comprising a tank body 1, a tank cover 2 covering the tank body 1, the tank cover 2 being sealed to the tank body 1; a centrifugal main shaft 3 extending from the tank cover 2 into the tank body 1, with a feeding chamber 4 at its center; a drive assembly 5 mounted on the tank cover 2 to drive the centrifugal main shaft 3 to rotate, the centrifugal main shaft 3 being coaxially connected to the output shaft of the drive assembly 5; a vacuum assembly used to evacuate the inside of the tank body 1 to achieve a vacuum state, and to perform vacuum degassing inside the tank body 1; m centrifugal components 6, where m ≥ 1, are installed at the end of the centrifugal main shaft 3; the m centrifugal components 6 are arranged sequentially on the centrifugal main shaft 3, each centrifugal component 6 including a centrifugal disc 60 mounted on the centrifugal main shaft 3 and multiple circular... The centrifugal main shaft 3 has equidistant outlet holes 61 and baffles 62 installed on the centrifugal main shaft 3 outside the outlet holes 61. The multiple outlet holes 61 in each centrifugal assembly are connected to the feed chamber 4. The slurry enters the feed chamber 4 in the center of the centrifugal main shaft 3 from the feed port 63 at the top of the centrifugal main shaft 3. The slurry flows downward and is thrown out from the multiple outlet holes 61 at the end of the centrifugal main shaft 3. The thrown slurry is blocked by the baffles 62 and falls onto the centrifugal disc 60 under the action of the baffles 62. The drive assembly 5 drives the centrifugal disc 60 to rotate, so that the slurry falling on the centrifugal disc 60 is thrown outward under the action of centrifugal force, separating the air bubbles in the slurry. The gas in the tank 1 is extracted by the vacuum assembly to remove the bubbles, which can effectively improve the defoaming efficiency.

[0030] See Figure 4 In this embodiment, in order to improve the uniform discharge effect, each centrifugal component 6 is provided with four discharge holes 61. The four discharge holes 61 are arranged in a circumferential array and are equidistantly opened on the centrifugal main shaft 3. This can make the slurry evenly distributed on the centrifugal disc 60. It can effectively overcome the defects in the prior art where the thickness of the material on the degassing disc cannot be controlled due to one discharge point, which prevents the exposure of micro bubbles and causes incomplete degassing, thus affecting product quality. This degassing machine sets four discharge holes 61 in each centrifugal component 6. The four discharge holes 61 are distributed in the east, west, south and north directions, which can effectively improve the uniformity of discharge and improve the degassing efficiency and degassing quality.

[0031] like Figure 3 and Figure 4As shown, the drive assembly 5 includes: a drive motor 50 mounted on the tank cover 2, a drive pulley 51 coaxially connected to the output shaft of the drive motor 50, and a driven pulley 53 connected to the drive pulley 51 via a synchronous belt 52. The driven pulley 53 is sleeved and mounted on the centrifugal main shaft 3. When the drive motor 50 operates, it drives the drive pulley 51 to rotate. The drive pulley 51 drives the driven pulley 53 to rotate via the synchronous belt 52, thereby driving the centrifugal main shaft 3 to rotate, which in turn drives the centrifugal disc 60 to rotate. The centrifugal disc 60 throws the slurry flowing out of the discharge hole 61 apart. Under the action of centrifugal force, the material and air bubbles are separated. The separated air bubbles are extracted by the vacuum assembly, realizing the degassing of the slurry and effectively improving the degassing efficiency.

[0032] See Figure 3 The bottom end of the centrifugal spindle 3 is sealed by a pressure cap 7. The center of the centrifugal spindle 3 is hollow, and the center of the centrifugal spindle 3 has a feed chamber 4. The bottom end of the centrifugal spindle 3 is sealed by a pressure cap 7, which seals the bottom end of the feed chamber 4 to ensure that the slurry flows out from the discharge hole 61. This degassing machine feeds from the center of the centrifugal spindle 3 and discharges from multiple discharge holes 61 around the centrifugal spindle 3. This overcomes the defect of traditional degassing machines that discharge from one place, resulting in uneven discharge and poor degassing effect. This degassing machine throws the slurry out from multiple discharge holes 61, so that the material is evenly distributed on the centrifugal disc 60, which can effectively and quickly separate the bubbles and effectively improve the degassing effect.

[0033] like Figure 1 and Figure 4 As shown, the centrifugal spindle 3 is rotatably connected to the tank cover 2 via a bearing assembly 8. The bearing assembly 8 includes a bearing seat fixed on the tank cover 2. The centrifugal spindle 3 is rotatably connected to the bearing seat via a bearing. The upper and lower ends of the bearing are limited by end caps. A mechanical seal is also fitted on the centrifugal spindle 3. In this embodiment, the centrifugal spindle is rotatably connected to the upper and lower parts of the bearing seat via two bearings arranged at different heights. An end cap for limiting the bearing is provided above the upper bearing. A mechanical seal is provided above the end cap. End caps are provided above and below the lower bearing. A mechanical seal is also provided above the end cap above the lower bearing.

[0034] See Figure 2 The centrifugal disc 60 is set in the shape of a disc. The slurry moves on the centrifugal disc 60 in a direction away from the centrifugal main shaft 3. The centrifugal disc 60 gradually thins from its center to its edge, forming a slope, which facilitates the movement of the slurry away from the centrifugal main shaft 3. The slope design of the centrifugal disc 60 can ensure that there is no material accumulation on the centrifugal disc 60, making degassing more thorough and effectively improving the degassing effect.

[0035] like Figure 4As shown, the baffle 62 and discharge port 61 in each centrifugal assembly 6 are located above the centrifugal disc 60. The baffle 62 restricts the discharge height of the centrifugal disc 60, and the bottom of the baffle 62 is lower than the discharge port 61. To achieve better results, the bottom of the baffle 62 is as close as possible to the upper surface of the centrifugal disc 60. The slurry in the feed chamber 4 flows out from the discharge port 61 and is thrown outward under the action of centrifugal force. The baffle limits the slurry thrown out from the discharge port 61, causing the slurry to adhere to the centrifugal disc 60 and be thrown outward. The slurry is evenly distributed on the centrifugal disc 60, which facilitates the separation of the slurry from the air bubbles and effectively improves the degassing efficiency.

[0036] See Figure 2 , Figure 3 and Figure 4 In this embodiment, m=2, and two centrifugal components 6 are installed on the centrifugal spindle 3 and spaced apart vertically. The centrifugal components 6 are arranged in two layers, and the degassing efficiency can be effectively increased through double-layer degassing. The degassing machine feeds from the inlet 63 at the top of the centrifugal spindle 3 and discharges from multiple outlet holes 61 at the end of the centrifugal spindle 3. Under the action of centrifugal force, the material is discharged evenly, and the slurry has a uniform thickness on the centrifugal disc 60 without material accumulation, which can greatly improve the degassing efficiency. The degassing efficiency meets the requirements of online operation. The degassing machine is online, with material feeding and discharging at the same time. There is no need to stop the machine during the discharge and feeding process, and it can continuously and uninterruptedly degas the slurry, which can effectively improve the degassing efficiency and achieve good degassing effect.

[0037] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
