Description

Technical Field

[0001] The utility model relates to the technical field of silicon micropowder processing, in particular to a drying device for silicon micropowder. Background Art

[0002] When drying existing silicon micropowder, it is usually directly put into a drying box, and air is introduced into the drying box through a hot air blower or other structure for drying. However, due to the high humidity in the initial stage of drying, the silicon micropowder is easy to stick together, which makes it difficult to dry and affects the drying efficiency.

[0003] For example, the utility model with application number 202020078454.1 discloses a drying device for silicon micropowder. The utility model breaks up the lumps in the silicon micropowder by rotating the breaking rod, so that the silicon micropowder can fully contact with the heated funnel-shaped heating plate, thereby achieving the effect of thoroughly drying the silicon micropowder. At the same time, the funnel-shaped heating plate that vibrates up and down can effectively prevent the device from being blocked.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This silicon micropowder drying device improves the drying efficiency of the silicon micropowder by breaking up the agglomerates of the silicon micropowder through the rotation of the breaking rod, but the contact range between the bottom and the heating plate is small, and the silicon micropowder is turned over only by up and down vibration, which limits the heating of the silicon micropowder and reduces the drying efficiency.

[0006] Therefore, a drying device for silicon micropowder is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a drying device for silicon micropowder to solve the related technical problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A drying device for silicon micropowder comprises a drying tank, wherein a motor is installed in the middle position of the top of the drying tank, a rotating shaft is fixed to the output shaft of the motor, a second bevel gear is fixed to the outside of the rotating shaft, an isolation plate is fixed to the middle position of the drying tank, an external pipe is evenly installed on the outside of the drying tank, a rotating tube is rotatably installed at one end of the external pipe, a sleeve is fixed to one end of the rotating tube, a hollow flap is evenly fixed to the outside of the sleeve, a first bevel gear is fixed to one end of the sleeve, and the first bevel gear is meshed with the second bevel gear.

[0010] Preferably, a movable plate and a fixed rod are respectively fixed on the outer side of the rotating shaft. Comb teeth are uniformly arranged at the bottom of the movable plate. A rolling plate is fixed on one side of the movable plate. A brush is fixed at the bottom of the fixed rod. A mesh plate is arranged on the top of the partition plate.

[0011] Preferably, mounting plates are symmetrically fixed inside the hollow flap. Movable covers are movably mounted on the tops of the hollow flaps. Air outlet holes are uniformly formed in the tops of the movable covers. Mounting bolts are threadedly mounted on the movable covers, and the bottom ends of the mounting bolts penetrate and extend to the bottom of the mounting plates. A separation net is arranged between the mounting plates and the movable covers.

[0012] Preferably, a protective shell is arranged at one end of the sleeve close to the first bevel gear, and the protective shell is sleeved on the outer side of the rotating shaft.

[0013] Preferably, an installation opening is formed at the connection between the rotating pipe and the drying tank, and a sealing ring is installed inside the installation opening.

The continuously stirred silica powder in contact with the hot air can increase the heating frequency and heating area of the silica powder, improve the uniformity of the silica powder being heated, and thus improve the drying efficiency of the drying device for silica powder;

[0017] Through the combined use of a movable plate, comb teeth, a rolling plate, a fixed rod, a brush and a mesh plate, when the motor drives the rotating shaft to rotate, the movable plate and the fixed rod also rotate. The comb teeth and the rolling plate at the bottom of the movable plate comb and crush the agglomerated silica powder, and then the crushed silica powder is swept onto the mesh plate by the brush at the bottom of the fixed rod and enters the bottom of the partition plate through the mesh plate for drying. The uncrushed silica powder is combed and rolled again until it is completely crushed and then can enter the bottom of the partition plate through the mesh plate, thereby improving the practicability of the drying device for silica powder;

[0018] Through the combined use of a mounting plate, a mounting bolt, a separation net and a movable cover, the mounting bolt is screwed upward in sequence so that the bottom end of the mounting bolt completely disengages from the mounting plate, and then the movable cover is removed from the hollow flap. At the same time, the separation net is disassembled and cleaned and dredged, thereby facilitating the maintenance and use of the drying device for silica powder. Description of the Drawings
