At the same time, air will enter the tank every time unloading and loading are performed, so the temperature and humidity inside the tank will change accordingly, which can easily cause chloroacetic acid to agglomerate and deteriorate.

[0008] Beneficial effects:

[0009] 1. The sealed storage device for chloroacetic acid can detect the temperature and humidity inside the tank body through a temperature and humidity sensor. When the temperature inside the tank body is higher than a preset value, the coolant can be transported to the inside of the heat exchange tube by driving a water pump, and then heat is exchanged with the chloroacetic acid inside the tank body through the heat exchange tube, ensuring that the chloroacetic acid can be stored in a low temperature state. The air inside the tank body can be discharged by driving a vacuum pump while reducing the temperature and humidity inside the tank body, avoiding direct long-term contact between chloroacetic acid and air, thereby ensuring that the chloroacetic acid inside the tank body is not easy to agglomerate and deteriorate.

[0010] 2. The sealed storage device for chloroacetic acid adopts a staggered distribution between the discharge pipe and the feed barrel through the coordinated use of the discharge pipe and the feed barrel, so that when the valve is opened and the screw rod is rotated for unloading, the chloroacetic acid inside the feed barrel is gradually discharged, and after the screw rod stops rotating, the chloroacetic acid inside the feed barrel can be blocked to prevent the chloroacetic acid inside the tank body from continuing to be transported to the inside of the feed barrel through the discharge pipe, thereby ensuring that the chloroacetic acid will not block the valve, facilitating the closing of the valve and facilitating the unloading operation.

The vacuum pump 7 is connected to an air intake pipe 17 connected to the inside of the first sealing plate 3. The bottom end of the air intake pipe 17 is connected to a one-way valve 18. The vacuum pump 7 is driven to evacuate the interior of the tank body 1 and discharge the air inside the tank body 1 at the same time with the cooperation of the air intake pipe 17 and the one-way valve 18, thereby reducing the air content inside the tank body 1, so that chloroacetic acid will not directly contact with the air on the inside of the tank body 1, ensuring that chloroacetic acid is not easy to deteriorate and agglomerate inside the tank body 1.

[0020] Among them, the cooling mechanism 6 includes a water pump 61 fixedly installed on one side of the tank body 1 and electrically connected to the controller. A radiator 62 fixedly installed on the tank body 1 and electrically connected to the controller is connected below the water pump 61. The water pump 61 is connected to the second O-type tube 11 through a first water pipe 63, and the radiator 62 is connected to the first O-type tube 10 through a second water pipe 64. Through the coordinated use of the first O-type tube 10, the second O-type tube 11, the first water pipe 63 and the second water pipe 64, the coolant can be circulated and transported to the inside of the heat exchange tube 9 under the drive of the water pump 61, thereby ensuring that the chloroacetic acid inside the tank body 1 can exchange heat with the coolant in time through the heat exchange tube 9, so that the chloroacetic acid can be stored at a low temperature inside the tank body 1.

[0021] Among them, the first sealing plate 3 is internally installed with an air pressure sensor 19 and a temperature and humidity sensor 20 located outside the first O-tube 10 and electrically connected to the controller. The air pressure inside the tank body 1 can be detected by the air pressure sensor 19. When the air pressure inside the tank body 1 is higher than the set value, the device can control the vacuum pump 7 to drive, and then the tank body 1 is pressure-maintained by the drive of the vacuum pump 7.

[0022] Among them, the sealing assembly 12 includes a sealing cover 121 threadedly sleeved on the outer side of the top end of the feed pipe 8, a storage barrel 122 located on the inner side of the feed pipe 8 is provided on the inner side of the sealing cover 121, and a sealing plug 123 is threadedly sleeved on the inner side of the top of the sealing cover 121, an air inlet groove 124 is opened inside the storage barrel 122, and a desiccant 125 is placed inside the storage barrel 122. The desiccant 125 can dry the moisture contained in the tank body 1, thereby further reducing the humidity inside the tank body 1, and when the temperature and humidity sensor 20 detects that the humidity inside the tank body 1 is higher than the set value, the device can issue an alarm reminder, so that the personnel can replace the desiccant 125 by removing the sealing plug 123.

[0023] Among them, the unloading mechanism 14 includes a spiral rod 141 rotatably connected to the inside of the feeding barrel 5, a sealing sleeve 142 fixedly sleeved on the outside of the feeding barrel 5, and a motor 143 located on the inner side of the sealing sleeve 142 and with the output shaft clamped inside one end of the spiral rod 141. The drive of the motor 143 can drive the spiral rod 141 to rotate, and the chloroacetic acid inside the feeding barrel 5 is transported to the inside of the discharge pipe 16, so as to facilitate the unloading operation of the chloroacetic acid by opening the valve 15. A controller 144 electrically connected to the motor 143 is provided inside one side of the sealing sleeve 142, and the drive of the motor 143 can be controlled by the controller 144. A slide rail 145 is provided on the inner side of the sealing sleeve 142, and a slide seat 146 arranged on the outer side of the motor 143 is slidably connected to the outer side of the slide rail 145. The cooperation of the slide rail 145 and the slide seat 146 facilitates the disassembly and assembly of the motor 143 on the inner side of the sealing sleeve 142.

[0024] When the device is working, the temperature and humidity inside the tank body 1 are detected by the temperature and humidity sensor 20. When the temperature is higher than the set value, the coolant is transported to the inside of the heat exchange tube 9 through the first water pipe 63 and the second O-type tube 11 by the drive of the water pump 61. After the coolant exchanges heat with the chloroacetic acid inside the tank body 1 through the heat exchange tube 9, it is transported to the inside of the radiator 62 through the first O-type tube 10 and the second water pipe 64 for cooling. The cooled coolant is transported to the inside of the heat exchange tube 9 again by the drive of the water pump 61. When the temperature and humidity sensor 20 detects that the temperature reaches the preset value, the water pump 61 and the radiator 62 are turned off by the controller. When the temperature and humidity sensor 20 detects that the humidity inside the tank body 1 is higher than the set value, the device can alarm and remind the personnel to replace the desiccant 125 by removing the sealing plug 123.

[0025] When the air pressure sensor 19 detects that the air pressure inside the tank body 1 is higher than the set value, the controller controls the vacuum pump 7 to start, and then evacuates the inside of the tank body 1. When the air pressure reaches the set value, the controller turns off the vacuum pump 7.
