Description

Technical Field

[0001] The utility model relates to the field of powder feeders, in particular to an anti-bridging agitator for powders in a cabin. Background Art

[0002] The "bridging" of a powder feeder refers to the phenomenon that bulk materials in the hopper of the powder feeder, such as powder or granules, form an arched structure above the outlet. Because it hinders the free flow of materials, it leads to serious production problems. However, the stirring powder feeder in the prior art does not have an anti-bridging function. If the bridging problem needs to be solved, employees need to operate it. Therefore, technical personnel in this field provide an in-cabin powder anti-bridging agitator to solve the problems raised in the above background technology. Utility Model Content

[0003] The utility model aims to provide an anti-bridging agitator for powder in a cabin to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an anti-bridging agitator for powders in a cabin comprises a powder temporary storage tank, a support is fixedly connected to the bottom of the powder temporary storage tank, a discharge pipe is communicated with the bottom of the powder temporary storage tank, a discharge inclined plane box is rotatably connected between the two sides of the support close to each other through a damping shaft, a top cover is sealed and fitted at the top opening of the powder temporary storage tank, a mounting cylinder is communicated at the top of the top cover, a motor is arranged on the top inner wall of the mounting cylinder, an output shaft of the motor passes through the top cover and extends into the powder temporary storage tank and is fixedly sleeved with a stirring shaft, a plurality of connecting pieces are fixedly connected to the outer wall of the stirring shaft, one side of each of the plurality of connecting pieces is fixedly connected with an arc-shaped scraper that fits the inner wall of the powder temporary storage tank, an auger is fixedly sleeved on the outer wall of the stirring shaft, and the bottom end of the auger extends to the discharge pipe, two powder inlet pipes are communicated at the top of the top cover, and a plug that passes through the mounting cylinder is electrically connected to the motor.

[0005] As a further solution of the utility model: one side of the plurality of arc-shaped scrapers close to each other is fixedly connected with an L-shaped scraper, and the L-shaped scraper fits the inner wall of the discharge pipe.

[0006] As a further solution of the utility model: a magnetic filter disc is adsorbed on the bottom outlet end of the discharge pipe, and the magnetic filter disc is located in the center of the two supports.

[0007] As a further solution of the utility model: the plurality of arc-shaped scrapers are located on both sides of the auger, and the auger is located between the sides where the plurality of L-shaped scrapers are close to each other.

[0008] As a further solution of the utility model: the plurality of powder inlet pipes are inclined pipes, and the plurality of powder inlet pipes are located directly above the auger.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. Powder can be poured into the powder temporary tank through multiple powder inlet pipes. The powder that falls from the powder inlet pipe into the powder temporary tank will fall onto the auger. When the plug is connected to the power supply, the motor can be powered. When the motor is started, the stirring shaft will be driven to rotate. The rotation of the stirring shaft will drive the auger to rotate. When the auger rotates, the powder will be transported to the discharge pipe and discharged. When the stirring shaft rotates, it will also drive the connecting piece, the arc scraper, and the L-shaped scraper to rotate. When the arc scraper rotates, it will rub against the inner wall of the powder temporary tank to scrape off the powder on the inner wall of the powder temporary tank. When the L-shaped scraper rotates, it will rub against the inner wall of the discharge pipe to scrape off the powder on the inner wall of the powder temporary tank. Because the two connecting pieces are relatively close to the outlet end of the powder feed pipe, the rotation of the two connecting pieces will generate friction with the outlet end of the powder feed pipe to reduce the residual amount of powder at the outlet end of the powder feed pipe, thereby avoiding the occurrence of the tower bridge phenomenon. Then, the cleaning of the arc scraper and the L-shaped scraper can not only clean the powder temporary tank and the discharge pipe, but also prevent the occurrence of the bridging phenomenon. The powder falling from the discharge pipe will fall onto the discharge bevel box and be discharged by the discharge bevel box. When the damping shaft is rotated, the discharge bevel box can be driven to rotate to adjust the powder discharge angle of the discharge bevel box. The magnetic filter disc is used to block the outlet end of the discharge pipe when it is not in use, thereby preventing other objects from entering the discharge pipe.

[0011] The utility model is easy to use. Starting the stirring shaft can drive the arc-shaped scraper, the L-shaped scraper and the auger to rotate at the same time. When the auger rotates, the powder can be transported to the discharge pipe for discharge. The L-shaped scraper and the arc-shaped scraper can clean the inner walls of the powder temporary storage tank and the discharge pipe at the same time. When the stirring shaft rotates, it will also generate friction with the outlet end of the powder inlet pipe to prevent the occurrence of bridging. BRIEF DESCRIPTION OF THE DRAWINGS

A motor 11 is arranged on the top inner wall of the mounting tube 1. The output shaft of the motor 11 passes through the top cover 3 and extends into the powder temporary storage tank 5 and is fixedly sleeved with a stirring shaft 12. A plurality of connecting pieces 13 are fixedly connected to the outer wall of the stirring shaft 12. One side of each of the plurality of connecting pieces 13 is fixedly connected with an arc-shaped scraper 14 that fits the inner wall of the powder temporary storage tank 5. An auger 16 is fixedly sleeved on the outer wall of the stirring shaft 12, and the bottom end of the auger 16 extends to the discharge pipe 7. There are two powder inlet pipes 2 connected to the top of the cylinder 3, and the motor 11 is electrically connected to a plug 4 that penetrates the mounting barrel 1. Powder can be poured into the powder temporary storage tank 5 through the multiple powder inlet pipes 2. The powder that falls from the powder inlet pipe 2 into the powder temporary storage tank 5 will fall onto the auger 16. When the plug 4 is connected to the power supply, the motor 11 can be powered. When the motor 11 is started, the stirring shaft 12 will be driven to rotate. The rotation of the stirring shaft 12 will drive the auger 16 to rotate. When the auger 16 rotates, the powder will be transported to the discharge pipe 7 and discharged. The stirring shaft 12 is rotating. At the same time, the connecting piece 13, the arc scraper 14 and the L-shaped scraper 15 will be driven to rotate. When the arc scraper 14 rotates, it will generate friction with the inner wall of the powder temporary storage tank 5 to scrape off the powder on the inner wall of the powder temporary storage tank 5, and when the L-shaped scraper 15 rotates, it will generate friction with the inner wall of the discharge pipe 7 to scrape off the powder on the inner wall of the powder temporary storage tank 5. Because the two connecting pieces 13 are closer to the outlet end of the powder inlet pipe 2, the rotation of the two connecting pieces 13 will generate friction with the outlet end of the powder inlet pipe 2 to reduce the residual powder at the outlet end of the powder inlet pipe 2.

[0019] In this embodiment, one side of the plurality of arc-shaped scrapers 14 close to each other is fixedly connected with an L-shaped scraper 15 , and the L-shaped scraper 15 fits against the inner wall of the discharge pipe 7 .

[0020] In this embodiment, a magnetic filter disc 8 is adsorbed on the bottom outlet end of the discharge pipe 7, and the magnetic filter disc 8 is located at the center of the two supports 6. The magnetic filter disc 8 is used to block the outlet end of the discharge pipe 7 when not in use, thereby preventing other objects from entering the discharge pipe 7.

[0021] In this embodiment, the plurality of arc-shaped scrapers 14 are located on both sides of the auger 16 , and the auger 16 is located between the sides where the plurality of L-shaped scrapers 15 are close to each other.

[0022] In this embodiment, the multiple powder inlet pipes 2 are inclined pipes, and the multiple powder inlet pipes 2 are located directly above the auger 16 .

[0023] The working principle of the utility model is as follows: powder can be poured into the powder temporary storage tank 5 through multiple powder inlet pipes 2, and the powder falling into the powder temporary storage tank 5 from the powder inlet pipe 2 will fall onto the auger 16. When the plug 4 is connected to the power supply, the motor 11 can be powered. When the motor 11 is started, the stirring shaft 12 will be driven to rotate, and the rotation of the stirring shaft 12 will drive the auger 16 to rotate. When the auger 16 rotates, the powder will be transported to the discharge pipe 7 and discharged. When the stirring shaft 12 rotates, it will also drive the connecting piece 13, the arc scraper 14, and the L-shaped scraper 15 to rotate. When the arc scraper 14 rotates, it will generate friction with the inner wall of the powder temporary storage tank 5 to scrape off the powder on the inner wall of the powder temporary storage tank 5, and when the L-shaped scraper 15 rotates, it will generate friction with the inner wall of the discharge pipe 7 to scrape off the powder. The powder on the inner wall of the powder temporary storage tank 5, because the two connecting pieces 13 are relatively close to the outlet end of the powder inlet pipe 2, the rotation of the two connecting pieces 13 will generate friction with the outlet end of the powder inlet pipe 2 to reduce the accumulation of powder at the outlet end of the powder inlet pipe 2, thereby avoiding the occurrence of the tower bridge phenomenon, and then the cleaning of the arc scraper 14 and the L-shaped scraper 15 can not only clean the powder temporary storage tank 5 and the discharge pipe 7 but also prevent the occurrence of the bridging phenomenon. The powder falling from the discharge pipe 7 will fall onto the discharge bevel box 9 and be discharged by the discharge bevel box 9. When the damping shaft 10 is rotated, the discharge bevel box 9 can be driven to rotate to adjust the powder discharge angle of the discharge bevel box 9. The magnetic filter disc 8 is used to block the outlet end of the discharge pipe 7 when not in use, thereby preventing other objects from entering the discharge pipe 7.
