Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a feeding device for chemical safety. Background Art

[0002] During the chemical production process, materials are fed through a feeder. Since some chemical powders are polluting, they often need to be closed during the feeding process. The feeder may be clogged with powder during feeding, but the feeder is closed, making it easy to clear. Currently, in order to avoid this situation, electromagnetic excitation vibration is often used to vibrate the discharge port of the feeder. However, this method has limited effectiveness and also generates a lot of noise during feeding. The blockage of the feeder discharge pipe is often caused by powder adhering to the inner wall, resulting in poor discharge, and some powders are prone to agglomeration, which in turn easily leads to blockage. Utility Model Content

[0003] The utility model provides a feeding device for chemical safety, which solves the above-mentioned deficiencies in the prior art, can avoid the problem of blockage during powder feeding, and has strong practicality.

[0005] A chemical safety feeding device includes a tank body, the lower end of the tank body is connected to a discharge pipe, the upper end of the tank body is provided with a feed pipe on the outer periphery, the upper end of the tank body is installed with an upper cover, and the feed pipe is provided with a feed cover. The feed pipe can be closed by the feed cover to prevent powder from diffusing outward and polluting the environment.

[0006] A motor is mounted on the upper cover, the output shaft of the motor is connected to a drive shaft via a coupling, a turntable is mounted on the lower end of the drive shaft, a scraper is mounted on the outer periphery of the turntable, a plurality of movable rods are passed through the turntable, the movable rods are provided with a lower ring, the lower ring is located on the lower side of the turntable, the lower ends of the movable rods extend into the discharge pipe, the upper ends of the movable rods are provided with an end plate, the upper ends of the movable rods are sleeved with a spring, the spring is located between the end plate and the turntable, the end plate is provided with a top post, a lower top ring is mounted on the lower wall of the upper cover, the lower end of the lower top ring is openly formed with a V-shaped groove, and the upper end of the top post acts on the lower end of the lower top ring. The scraper is rotated by the motor and rotates. During the rotation process, the scraper can scrape the inner wall of the tank body, thereby preventing powder from adhering to the tank wall and causing poor powder discharge. In addition, the reciprocating movable rod can unclog the discharge pipe during its movement, thereby preventing the presence of lumps of powder from causing blockage.

[0007] Furthermore, in order to facilitate feeding, the feed pipe is set at an angle, and the outer end of the feed pipe extends outward at an angle.

[0008] Furthermore, in order to facilitate discharge, the lower end of the tank body is funnel-shaped, and the upper end is a large end.

[0009] Furthermore, in order to improve the effect of scraping and cleaning the inner wall of the tank, the scraper includes a vertical scraper tangent to the inner wall of the tank, and an inclined scraper is provided at the lower end of the vertical scraper, and the outer wall of the inclined scraper is tangent to the lower end of the tank.

[0010] Furthermore, in order to enhance the stirring effect of the movable rod, a plurality of stirring blades are provided at the lower end of the movable rod.

[0011] Furthermore, in order to improve the flexibility of the movement of the top column, the upper end of the top column is formed into a spherical structure.

[0012] Furthermore, in order to improve the sealing effect of the feed cover, a pair of L-shaped plates are provided on both sides of the feed pipe, the feed cover is passed through the L-shaped plates, a feed hopper is provided at the upper end of the feed cover, and an end plate is provided at the lower end of the feed cover.
