Description

Technical Field

[0001] The utility model belongs to the technical field of capsule production, in particular to a vacuum-pumped automatic degassing aerosol can. Background Art

[0002] Sol is the first step in the capsule production process. The quality of the glue liquid directly affects various indicators of product quality, especially the vacuuming link in the sol process is very critical. The glue liquid will produce a lot of foam during the vacuuming process. When the vacuum reaches a certain pressure, it needs to be exhausted and the pressure is relieved. The glue liquid will be sucked into the vacuum pipe. The existing sol tank is equipped with a manual ball valve for exhaust. The exhaust is achieved by manually controlling the opening of the ball valve. When multiple sol tanks are vacuumed at the same time, the exhaust is not timely and a large amount of glue liquid is sucked away by the vacuum pipe, resulting in a large amount of raw materials being wasted. The excessive exhaust volume affects the vacuum pressure and prolongs the sol time, affecting the glue liquid quality and production progress, resulting in rework waste, action waste, waiting waste, etc. According to statistics: using manual operation method, each tank of glue liquid is calculated as 50kg gelatin, and the waste is 0.11%.

[0016] like Figure 1-2 , a vacuum automatic degassing sol tank includes: a tank body 1, a top cover 2, a liquid level sensor 3, an infrared foam sensor 4, a motor 5, a defoaming blade 6, a vacuum pump 7, an electromagnetic valve 8, a stop valve 9, a stirring blade 11, a controller 12, and a one-way bearing 13; wherein, a top cover 2 is provided on the tank body 1, and a liquid level sensor 3, an infrared foam sensor 4, and a motor 5 are provided on the top cover 2. The liquid level sensor 3 is a floating sensor for detecting the height of the sol liquid level. The motor 5 is inverted and located in the center of the top cover 2. The output shaft of the motor 5 is connected to the drive shaft. The drive shaft It extends through the top cover 2 into the lower part of the tank body 1, and a one-way bearing 13 is provided at the lower end of the transmission shaft, and a stirring blade 11 is distributed and connected on the rotating part of the one-way bearing 13; a number of defoaming blades 6 are also horizontally distributed and connected on the transmission shaft near the top cover 2; a pipe 10 and a pipe 2 14 are also connected to the top cover 2, a vacuum pump 7 is provided at the outer outlet of the pipe 10, and a solenoid valve 8 and a stop valve 9 are provided in parallel at the outer outlet of the pipe 2 14, and a controller 12 controls the connection of the liquid level sensor 3, the infrared foam sensor 4, the motor 5, the vacuum pump 7, and the solenoid valve 8 respectively.

[0017] like Figure 2The defoaming blade 6 includes: a sheet body 601, a cavity 602, a cavity opening 603, and a honeycomb hole 604. The left side of the sheet body 601 is connected to the transmission shaft. The cavity 602 is set inside the sheet body 601. The cavity opening 603 is set on the front of the cavity 602.

[0018] Implementation method:

[0019] like Figure 1-2 The tank body 1 is filled with sol liquid, and the controller 12 controls the motor 5 to drive the transmission shaft to rotate counterclockwise. The one-way bearing 13 transmits torque to make the stirring blade 11 rotate to achieve stirring. The liquid level sensor 3 feeds back the height of the sol liquid to the controller 12. The controller 12 controls the vacuum pump 7 to work and evacuate the liquid. Bubbles are generated in the sol liquid. The infrared bubble sensor 4 senses the bubble height and feeds back a signal to the controller 12. The controller 12 controls the solenoid valve 8 to open and exhaust. Alternatively, when the bubbles are detected to diffuse to the height of the defoaming blade 6, the controller 12 controls the motor 5 to drive the transmission shaft to rotate clockwise. The one-way bearing 13 does not transmit torque and only drives the defoaming blade 6 to rotate at high speed. The bubbles enter the cavity 602 of the sheet body 601 through the cavity opening 603. The bubbles are separated and defoamed by the centrifugal force and can also be deflated by manually operating the stop valve 9.
