Description

Technical Field

[0001] The utility model relates to the technical field of magnesium nitrate crystallization, in particular to evaporation equipment for producing and processing crystal magnesium nitrate. Background Art

[0002] Evaporation is the process of heating a solution to its boiling point and causing it to evaporate. Crystallization is the process of supersaturating a solution to produce crystals. In chemistry, evaporation and crystallization are often used together, as the purpose of evaporation is generally to evaporate the solvent in the solution, thereby supersaturating the solution to produce a solute, which in turn causes it to crystallize.

[0003] For example, the announcement number "CN214551219U" is an evaporation device for the production and processing of crystalline magnesium nitrate. The magnesium nitrate solution is added to the interior of the evaporation box body through a feed hopper. The heating plate heats the magnesium nitrate solution under the action of a power device to evaporate the magnesium nitrate. The stirring rod rotates under the action of the power device, and the stirring rod drives the stirring rod to rotate, and the stirring rod drives the scraper to rotate. The stirring rod can accelerate the evaporation efficiency of the magnesium nitrate, and the processing efficiency is higher. However, the evaporation device for the production and processing of crystalline magnesium nitrate has a scraper that can only scrape the crystals in the evaporation barrel to the lower end of the evaporation barrel, and then the staff need to manually collect them, which increases the physical strength of the staff and thus increases the manual labor. At the same time, the evaporation device for the production and processing of crystalline magnesium nitrate has only one exhaust hole on the top and is located on the left side. The steam is discharged slowly, and the hot air is discharged slowly, so it will accumulate on the top, resulting in an excessively high water molecule content in the evaporation box, which makes the evaporation efficiency low and thus the work efficiency low. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the scraper of the evaporation equipment for the production and processing of crystalline magnesium nitrate can only scrape the crystals in the evaporation barrel to the lower end of the evaporation barrel, and then the staff need to manually collect them, which increases the physical strength of the staff and thus increases the manual labor; at the same time, the evaporation equipment for the production and processing of crystalline magnesium nitrate has only one exhaust hole on the top and is located on the left side, and the hot air is discharged slowly, so it will gather on the top, resulting in an excessively high content of water molecules in the evaporation box, thereby making the evaporation efficiency low and thus making the work efficiency low. The utility model provides an evaporation equipment for the production and processing of crystalline magnesium nitrate.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An evaporation device for producing and processing crystalline magnesium nitrate is designed, comprising a base plate, an evaporation barrel fixedly connected to the upper end of the base plate, a first shell fixedly connected to the right protrusion of the evaporation barrel, a swing mechanism provided inside the first shell, a second shell fixedly connected to the upper end of the evaporation barrel, a rotating mechanism provided inside the second shell, a heating plate installed on the outer wall of the evaporation barrel, and a discharge pipe fixedly connected to the inner wall of the lower end of the evaporation barrel.

[0011] Preferably, the outer wall of the scraper is in contact with the inner wall of the evaporation barrel, and the outer wall of the second motor is fixedly connected to the second outer shell.

[0012] The utility model provides an evaporation device for producing and processing crystalline magnesium nitrate, which has the following beneficial effects: through the cooperation of the rotating mechanism and the evaporation barrel, the output shaft of the second motor rotates to drive the upper first bevel gear to rotate, and the upper first bevel gear rotates through the second bevel gear to drive the lower first bevel gear to rotate synchronously in the opposite direction. The rotation of the upper first bevel gear drives the stirring rod to rotate forward, and the rotation of the lower first bevel gear drives the scraper to rotate reversely. The reverse synchronous rotation of the stirring rod and the scraper can make the flow speed of the magnesium nitrate solution in the evaporation box faster, thereby improving the evaporation speed of the magnesium nitrate solution.

The wind head can discharge the steam at the upper end of the evaporating barrel from the through hole on the left side of the evaporating barrel. The steam at the upper end of the evaporating barrel is quickly discharged from the through hole on the left side of the evaporating barrel through the hot air blower and the swing mechanism, thereby increasing the air circulation speed in the evaporating barrel, preventing steam accumulation, thereby increasing the evaporation speed of the magnesium nitrate solution, and thereby improving work efficiency.

[0029] Working principle:

[0030] During the production of magnesium nitrate, magnesium nitrate crystals are prepared by evaporation equipment.

[0031] Preparation:

[0032] The staff transports the magnesium nitrate solution into the evaporation barrel 2 through the feed pipe at the upper end of the evaporation barrel 2 (such as Figure 2 ), the amount of infusion does not exceed the height of the heating plate 9, and then the heating plate 9 is started to heat the evaporation barrel 2.

[0033] Crystallization process:

[0034] Start the first motor 301 (such as Figure 4), the output shaft of the first motor 301 rotates to drive the reciprocating screw 302 to rotate, the reciprocating screw 302 rotates to drive the rack 303 to move up and down, the rack 303 moves up and down to drive the gear 304 to rotate back and forth, the reciprocating rotation of the gear 304 drives the rotating rod 305 to rotate back and forth, and the maximum distance that the rack 303 can move can only drive the gear 304 to rotate ninety degrees, so the reciprocating movement of the rack 303 drives the gear 304 to rotate back and forth and swing horizontally ninety degrees, the rotation of the gear 304 drives the rotating rod 305 to swing back and forth, the rotation of the rotating rod 305 drives the wind head 6 to swing, and then the hot air blower 5 is started, and the hot air blower 5 delivers air into the wind head 6. The swing of the wind head 6 can discharge the steam above the evaporation barrel 2 from the through hole on the left side of the evaporation barrel 2 (such as Figure 2 ), the steam contains a large number of water molecules. If a large amount of steam accumulates in the drying drum 2 and cannot be discharged, the water molecules in the drying drum 2 will increase. This is because evaporation is a dynamic process in which water molecules enter the air and water vapor in the air enters the water. Under a constant rate of water molecules entering the air, the higher the air humidity, the more water vapor enters the water from the air, and therefore the slower the evaporation. This leads to a decrease in the evaporation efficiency of the drying drum 2. Therefore, after the steam is discharged, a large number of water molecules will be taken away, thereby increasing the evaporation rate;

[0035] Then start the second motor 801 (such as Figure 5 ), the output shaft of the second motor 801 rotates to drive the upper first bevel gear 802 to rotate, and the upper first bevel gear 802 rotates through the second bevel gear 803 to drive the lower first bevel gear 802 to rotate synchronously in the opposite direction, and the upper first bevel gear 802 rotates to drive the stirring rod 805 to rotate forward, and the lower first bevel gear 802 rotates to drive the scraper 804 to rotate in the opposite direction. The stirring rod 805 and the scraper 804 rotate synchronously in the opposite directions to make the magnesium nitrate solution in the evaporation box 2 flow faster, thereby increasing the evaporation speed of the magnesium nitrate solution. When the magnesium nitrate solution is completely evaporated, the scraper 804 continues to rotate to scrape off the magnesium nitrate crystals on the inner wall of the evaporation barrel 2 (such as Figure 2 ), at the same time, place the collection box at the lower end discharge pipe 10 of the evaporation barrel 2 and open the valve of the lower end discharge pipe 10. The scraped crystals can be discharged from the discharge pipe 10 into the collection box through the slope of the lower end of the evaporation barrel 2, thereby realizing the collection of the evaporated crystals of the magnesium nitrate solution. After all is completed, turn off all power supplies.
