Description

Technical Field

[0001] This utility model relates to the field of magnesium sulfate heptahydrate preparation technology, and in particular to a drying device for preparing magnesium sulfate heptahydrate. Background Technology

[0002] Magnesium sulfate heptahydrate, also known as sulfadiazine, bitter salt, esperidin salt, or Epsom salt (chemical formula MgSO4·7H2O), is a white or colorless needle-like or oblique columnar crystal. It is odorless, cool, and slightly bitter.

[0003] Drying is necessary in the preparation of magnesium sulfate heptahydrate to improve product purity and quality. Existing drying equipment typically involves directly heating large quantities of magnesium sulfate heptahydrate together, making it difficult to remove internal moisture. Furthermore, the low density of magnesium sulfate heptahydrate makes it prone to clumping, hindering rapid moisture removal and impacting drying efficiency. Therefore, there is an urgent need to develop a drying device that disperses the material for easier moisture removal, increases the material's looseness through vibration to expand the drying area, and uses airflow to expel moisture, resulting in higher drying efficiency for magnesium sulfate heptahydrate. This device would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a drying apparatus for producing magnesium sulfate heptahydrate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drying apparatus for producing magnesium sulfate heptahydrate includes a drying chamber, an auxiliary drying mechanism, an exhaust pipe, an air supply mechanism, and discharge boxes. Multiple discharge boxes are fixedly installed inside the drying chamber, and an electric heater is fixedly installed at the bottom of each discharge box. The auxiliary drying mechanism includes a motor, a turntable, a guide rod, a lifting plate, and elastic striking balls. The motor is fixed to the top of the drying chamber, and a turntable is fixed to the output shaft of the motor. A guide rod is fixed to the front side of the turntable, passing through and slidingly contacting the lifting plate. The lifting plate has a slotted groove for the guide rod to slide, extending into the drying chamber and slidingly contacting it. Multiple elastic striking balls are fixed to the side of the lifting plate, each located below a discharge box. The air supply mechanism includes a fan, a main pipe, and air outlets. The fan is placed on the ground, and its outlet is fixed to the main pipe. The main pipe extends into the drying chamber, with its top sealed. Multiple air outlets are installed on the side of the main pipe.

[0007] Preferably, the multiple material feeding boxes are arranged evenly vertically.

[0008] Preferably, each of the air outlets is located on the side of a material discharge box.

[0009] Preferably, the front side of the drying oven is connected to a door via a hinge, and a latch that can be detachably installed on the drying oven and inserted into the door is also provided.

[0010] The beneficial effects of this utility model are as follows: In the drying device for producing magnesium sulfate heptahydrate, the magnesium sulfate heptahydrate is first placed separately into multiple feeding boxes to reduce the density and facilitate moisture drainage. Then, the box door is closed, and the magnesium sulfate heptahydrate in the feeding boxes is heated and dried by an electric heater. A motor drives a turntable and guide rod to rotate, which in turn drives a lifting plate to move up and down. The lifting plate drives elastic striking balls to move up and down, causing the feeding boxes to vibrate and rub against each other. Under the action of vibration, the magnesium sulfate heptahydrate in the feeding boxes rubs and collides with each other, making it more loose, preventing clumping, and increasing the drying area. Moreover, the vibration causes the internal voids of the magnesium sulfate heptahydrate to constantly change, facilitating air circulation to remove moisture. At the same time, a fan blows air into the main tube, and the airflow is blown to the side of the feeding boxes through the air outlet. The airflow carries away the moisture discharged from the feeding boxes, and the moisture is discharged from the exhaust pipe. In summary, this invention disperses the materials for easy moisture removal, while vibration increases the looseness of the materials, expands the drying area, and airflow drives the moisture outward, resulting in higher drying efficiency.

Multiple feeding boxes 7 are fixedly installed inside the drying chamber 1, and are evenly arranged vertically. Each feeding box 7 has a heater 8 fixedly installed at its bottom. The feeding boxes 7 are used to hold the magnesium sulfate heptahydrate to be dried. The auxiliary drying mechanism 4 includes a motor 401, a turntable 402, a guide rod 403, a lifting plate 404, and an elastic striking ball head 405. The motor 401 is fixed to the top of the drying chamber 1. The turntable 402 is fixed to the output shaft of the motor 401. The guide rod 403 is fixed to the front side of the turntable 402, and the guide rod 403 passes through the lifting plate 404 and connects with... The lifting plate 404 is provided with a sliding groove 4041 for sliding the guide rod 403. The lifting plate 404 extends into the drying chamber 1 and slides in contact with it. Multiple elastic striking ball heads 405 are fixed on the side of the lifting plate 404. Each elastic striking ball head 405 is located on the lower side of a material box 7. The air supply mechanism 6 includes: a fan 601, a main tube 602 and an air outlet 603. The fan 601 is placed on the ground. The air outlet of the fan 601 is fixed to the main tube 602.

[0023] Working principle: In this drying device for producing magnesium sulfate heptahydrate, the magnesium sulfate heptahydrate is first placed separately into multiple feeding boxes 7 to reduce the density and facilitate moisture drainage. Then, the box door 2 is closed, and the magnesium sulfate heptahydrate in the feeding boxes 7 is heated and dried by the electric heater 8. The motor 401 drives the turntable 402 and guide rod 403 to rotate. The rotation of the guide rod 403 drives the lifting plate 404 to move up and down. The lifting plate 404 drives the elastic striking ball head 405 to move up and down, thereby drying the magnesium sulfate heptahydrate. The head 405 taps and vibrates the discharge box 7. Under the action of vibration, the magnesium sulfate heptahydrate inside the discharge box 7 rubs and collides with each other, making it more loose, preventing clumping, increasing the drying area, and the vibration will make the internal gaps of the magnesium sulfate heptahydrate constantly change, which facilitates air circulation to remove moisture. At the same time, the fan 601 blows air into the main tube 602, and the airflow is blown to the side of the discharge box 7 through the air outlet 603. The airflow carries away the moisture discharged from the discharge box 7, and the moisture is discharged from the exhaust pipe 5.
