Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum oxide powder processing, in particular to a drying bin for aluminum oxide powder. Background Art

[0002] Alumina is a high-hardness compound and an ionic crystal that can be ionized at high temperatures. It is often used to make refractory materials. After processing alumina into powdered material, it is necessary to ensure that the alumina powder is dry to facilitate the preservation of alumina.

[0003] The patent with publication number CN218329070U discloses a drying device for activated alumina, which uses a new type of heating plate for heating, and uses a rotating shaft and a reamer to stir the alumina powder, thereby stirring the alumina powder in the drying cylinder to facilitate uniform drying of the alumina powder.

[0004] However, when the above device is in use, the heating position is fixed and the stirring structure is single, which may easily lead to incomplete drying of some powders, affecting the drying quality. In addition, some alumina powder adheres to the side wall of the drying cylinder and forms lumps after drying, affecting the use of the drying cylinder. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing device is not conducive to uniform drying of aluminum oxide powder when in use, affecting the drying quality, and lacks cleaning of the side wall of the drying cylinder, which is not conducive to subsequent use.

[0006] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a drying bin for aluminum oxide powder, including a bin tank, on which a feed pipe and a discharge pipe are provided, and also including a stirring and drying mechanism and a reverse scraping mechanism arranged on the bin tank; the stirring and drying mechanism includes a motor and a branch pipe, the motor is arranged on the bottom wall of the bin tank, the output end of the motor is connected to a connecting pipe, the connecting pipe is rotatably arranged in the bin tank, the connecting pipe is connected to a hot air component, the branch pipe is penetrated through the side wall of the connecting pipe, and the side wall of the branch pipe is provided with a spray hole.

[0007] Furthermore, the hot air assembly includes a hot air blower and an air duct, the hot air blower is arranged on the top wall of the tank, one end of the air duct is connected to the hot air blower, and the other end of the air duct is rotatably connected to the connecting pipe.

[0008] Furthermore, the reverse scraping mechanism includes a collar and a support rod, wherein the collar is rotatably mounted on the top wall of the tank, a reversing assembly is provided on the collar, the support rod is disposed on the side wall of the collar, and a scraper is provided at the end of the support rod.

[0009] Furthermore, the reversing assembly includes a ratchet and a spring sheet, wherein the ratchet is arranged on the inner side wall of the collar, and the spring sheet is arranged on the side wall of the connecting tube, and the spring sheet is unidirectionally meshed with the ratchet.

[0010] Preferably, the motor is a stepper motor.

[0011] The utility model adopts the above structure to achieve the following beneficial effects:

[0012] 1. By setting the connecting pipe, branch pipe and spray hole, and cooperating with the hot air blower and air duct, the hot air can be sent into the branch pipe and sprayed out from the spray hole to heat and dry different positions in the tank. At the same time, the motor drive can drive the connecting pipe to rotate, so that the branch pipe rotates with it, and the spray hole position is changed, thereby further improving the drying effect of the hot air;

[0013] 2. By setting a collar, using a ratchet and a spring sheet, the connecting pipe can drive the ratchet to rotate when it rotates in the opposite direction, and use a support rod and a scraper to clean the side wall of the tank, which can effectively prevent the alumina powder from clumping and adhering to the tank.
