Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bromine drying, in particular to a bromine high-efficiency drying device. Background Art
[0002] Bromine is an important chemical raw material, which is widely used in flame retardants, fire extinguishing agents, refrigerants, photosensitive materials, medicines, pesticides, oil fields and other industries. Industrial crude bromine contains a certain amount of water (dissolved water and emulsified water), which not only affects the quality and application of the product, but also has much greater corrosiveness than dry bromine.
[0003] Bromine dehydration and drying methods include: 1. Wet method, i.e. drying with sulfuric acid; 2. Dry method, i.e. using drying plates to dehydrate bromine. Among them, the wet method using sulfuric acid for drying is highly corrosive to the equipment, and concentrated sulfuric acid is relatively dangerous, so the dry method is generally used to dehydrate bromine.
[0004] The existing bromine drying equipment has gradually exposed its shortcomings during use, mainly in the following aspects:
[0005] First, the drying plate is usually fixed in the drying tank by fixing bolts. When replacing the drying plate, the fixing bolts need to be removed first, and then the drying plate is replaced. After the replacement is completed, the fixing bolts are screwed in again. The replacement process of the drying plate is cumbersome, time-consuming and labor-intensive, and there is no reference basis for whether the drying plate needs to be replaced. The drying plate may have poor moisture absorption effect due to long-term use, which affects the drying effect of bromine.
[0006] Second, there are many filling layers for absorbing moisture inside the drying plate, and the resistance of bromine gas is relatively large when passing through the drying plate. Therefore, the speed of bromine gas passing through the drying plate is relatively slow, resulting in a long drying cycle for bromine, which affects the drying efficiency of bromine.
[0007] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

The telescopic ends of the two telescopic cylinders 5 are fixedly connected to the two fixed plates 6 .
[0072] The working principle of this device is:
[0073] When drying the bromine gas, the bromine gas enters the lifting tank 10 through the air intake pipe 11 and the air intake check valve 12, and the driving motor 9 drives the driving wheel 32, the transmission belt 36, the limiting wheel 33, the driven wheel 35 and the two reciprocating screws 29 to rotate, thereby driving the lifting block 28, the driven plate 31, the lifting plate 34, the connecting rod 37 and the piston 38 to vertically reciprocate and lift. When the piston 38 descends, the bromine gas in the lifting tank 10 is compressed, so that the bromine gas quickly passes through the drying plate 16 for drying. The dried bromine gas is discharged to the outside of the drying tank 3 through the gas collecting hopper 40, the exhaust check valve 41 and the exhaust pipe 1. When the piston 38 rises, the internal air pressure of the lifting tank 10 is reduced, so that the bromine gas in the air intake pipe 11 can quickly enter the lifting tank 10. The air intake check valve 12 and the exhaust check valve 41 can only allow the bromine gas to pass in one direction, preventing the bromine gas from flowing in the opposite direction, thereby realizing that the bromine gas quickly passes through the drying plate 16, and improving the drying efficiency of the bromine gas.
[0074] The gas humidity meter 2 can detect the humidity of the bromine gas in the exhaust pipe 1 in real time. When the humidity of the bromine gas reaches the warning value, the drying plate 16 is replaced to prevent the poor drying effect of the bromine gas due to the long-term use of the drying plate 16;
[0075] When the drying plate 16 is replaced, the control motor 4 rotates forward and drives the driving gear 24, the inner gear ring 13 and the four driven gears 21 to rotate, thereby driving the four driven racks 22, the four sliding plates 23, the four sliding arc plates 18 and the four fixed arc plates 17 to slide relative to each other, the four sliding arc plates 18 are separated from the drying plate 16, the four fixed arc plates 17 are separated from the ventilation pipe 39, the two telescopic cylinders 5 drive the lifting tank 10 and the ventilation pipe 39 to rise, and at the same time the rubber ring 27 is separated from the avoidance groove 14. When the lifting tank 10 rises, When it reaches the highest position, the drying plate 16 on the top of the limiting frame 26 is replaced. After the replacement is completed, the two telescopic cylinders 5 descend until the lifting tank 10 abuts against the drying tank 3, and the rubber ring 27 enters the avoidance groove 14 to form a sealing structure, and the driving motor 9 rotates in the opposite direction until the four sliding arc plates 18 and the four fixed arc plates 17 correspond to the drying plate 16 and the ventilation pipe 39, and the replacement of the drying plate 16 is completed, so that the drying plate 16 can be quickly replaced, and the replacement process saves time and effort, thereby improving the practicality of the equipment.
