Description

Technical Field

[0001] The utility model relates to the technical field of distillation machines, and more specifically to a low-temperature cooling automatic reflux unit of a distillation machine. Background Art

[0002] A distiller is a device used to separate liquid mixtures. It uses the difference in boiling points of different liquid components to achieve separation. Distillation is usually used to purify liquids, remove impurities or extract specific components. A distiller can perform different operations as needed, such as simple distillation, fractional distillation, vacuum distillation, etc.

[0003] The utility model with announcement number CN216366652U discloses a simple laboratory distillation reflux device, including a base plate and a raised base. A raised base is provided at one end of the top surface of the base plate, an electromagnetic heating plate is provided on the top of the raised base, and a distillation flask is placed above the electromagnetic heating plate. The steam passes through a first connecting pipe and reaches the guide pipe. At this time, the cold air produced by the valve reaches the condenser through the outlet pipe, and then is discharged from the air pipe to the cooling cylinder. After that, the cold air in the cooling cylinder is re-discharged into the valve through the reflux pipe. The flow rate of the cold air is accelerated by starting the air pump, thereby realizing the recycling of the cold air.

[0004] When the above patent is in use, the cold air in the condenser condenses the steam reaching the guide tube, and under the guiding effect of the guide tube, the steam reaches the collecting bottle through the first connecting tube, and finally the fluid collected in the collecting bottle is put into the distillation bottle again. Manual addition of fluid is required, and the labor intensity of the staff is high. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-temperature cooling automatic reflux unit of a distillation machine, comprising a sealing piston, the top end of the sealing piston is fixedly connected to a first conduit, one end of the first conduit is fixedly installed with a condenser, the side of the condenser away from the first conduit is fixedly connected to a second conduit, the bottom end of the second conduit is fixedly connected to a collecting tube, the bottom end of the collecting tube is fixedly connected to a third conduit, and one end of the third conduit away from the collecting tube is fixedly connected to the first conduit, an electromagnetic valve is fixedly installed on the third conduit, a control component is provided inside the collecting tube, and the control component includes a top block, an air bag, a waterproof button and a fixing plate.

[0007] It is worth mentioning that the sealing piston is installed on the distillation machine, and the steam enters the condenser through the first conduit. The condenser cools the steam at a low temperature, and the steam is cooled into liquid. The airbag floats on the liquid. The buoyancy of the airbag is large, and the friction between the two sliders and the two vertical rods is small, so that the liquid can easily drive the airbag to move upward.

[0008] Furthermore, the top block and the bottom end of the airbag are both fixedly connected to the fixing plate, and the top block is located inside the airbag, and the waterproof button is located on the top of the top block.

[0009] Furthermore, a support plate is fixedly connected inside the collecting tube, and a waterproof button is fixedly installed on the bottom end of the support plate.

[0010] It can be seen that in the above technical solution, it is convenient to support the waterproof button.

[0011] Furthermore, two sliding blocks are fixedly connected to the outer wall of the fixed plate, and vertical rods are movably provided on the two sliding blocks, and the two vertical rods are fixedly connected to the collecting barrel.

[0012] It can be seen that in the above technical solution, the fixing plate drives the two sliders to slide on the two vertical rods respectively, which can prevent the airbag from deflecting when moving vertically.

[0013] Furthermore, a thermometer is movably provided on one side of the first conduit, and the thermometer is fixedly installed on the top of the sealing piston.

[0014] It can be seen that in the above technical solution, the temperature of the steam can be detected by setting a thermometer.

[0016] Furthermore, two transparent plates are fixedly mounted on the collecting cylinder.

[0017] Technical effects and advantages of the utility model:

[0018] 1. The utility model cools the steam at low temperature through the condenser, and the steam is cooled into liquid and flows into the collecting tube through the second conduit. The airbag floats on the liquid. When the liquid in the collecting tube increases, the airbag starts to move upward, thereby driving the fixing plate to move upward, and then driving the top block to move upward. When the top block squeezes the waterproof button, the waterproof button controls the electromagnetic valve to work, so that the electromagnetic valve is in an open state, and the liquid in the collecting tube automatically flows back to the first conduit through the third conduit. The structure is simple and the labor intensity of the staff is effectively reduced.

[0019] 2. The utility model provides a transparent plate to facilitate observation of the liquid position in the collecting tube, and provides two handles to facilitate lifting the sealing piston. The utility model has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
