Powder materials are usually used in large quantities in the form of powder and need to be safely stored and provided to the production line. Strict screening is required before the powder materials are stored. The existing devices are slow in screening powders, which is time-consuming and labor-intensive, seriously affecting work efficiency and not conducive to loading large amounts of powders.

[0003] The patent with patent number CN202011350920.8 discloses a powder storage device for powder metallurgy. The internal feeding device of the patent can perform double screening before powder storage. At the same time, the circulating drying device can circulate and dry the inside of the storage bin to prevent uneven drying of the internal material during the drying process and form a humidity ladder.

It improves the shortcomings of the existing device, has high practicality and market prospects, and is suitable for large-scale promotion and use. Although the patent solves the above problems, there are still problems that the screening device is too common, and the powder needs to be screened layer by layer, which has low feeding efficiency and seriously affects the work efficiency.

The device performs multi-layer screening on the powder material without affecting the feeding efficiency, which not only improves the screening accuracy but also improves the processing efficiency, and is more convenient to collect the screened coarse material, thereby improving the work efficiency of the staff.

[0006] According to the above technical solution, a deoxygenation device is provided on the left side of the fine material channel, and the deoxygenation device includes a nitrogen filling structure and a uniform contact structure. The nitrogen filling structure includes a nitrogen generator, a nozzle, a second rotating shaft, and a turbine. The nitrogen generator is fixedly connected to the bottom of the bracket, and the nozzle is fixedly connected above the nitrogen generator. The second rotating shaft rotates and penetrates to the middle of the storage tank. The turbine is fixedly connected to the bottom of the second rotating shaft. The uniform contact structure includes a boosting chamber, an air outlet mesh tube, a stirring plate, an air cavity, and a pressure piston. The boosting chamber is fixedly connected to the bottom of the storage tank, the air outlet mesh tube is fixedly connected above the boosting chamber, the stirring plate is fixedly connected to the surface of the second rotating shaft, the air cavity is fixedly connected above the boosting chamber, and the pressure piston is slidably connected to the inside of the air cavity. The nitrogen generator is fixedly connected to the bottom surface of the storage tank, and the nozzle penetrates to the bottom of the storage tank. The bottom end of the pressure piston is fixedly connected to a spring and the spring is fixedly connected to the inside of the air cavity. The nitrogen generator injects nitrogen into the nozzle, and the nozzle will The nitrogen is sprayed into the boost chamber, and then enters the air outlet net cylinder through the boost chamber. At this time, the motor drives the second shaft to rotate, and the second shaft drives the turbine to rotate. When the nitrogen blows upward, it contacts the turbine to form a vortex and diverges to the surroundings. When part of the nitrogen rises to the upper part of the air outlet net cylinder, it will also be stirred by the stirring paddle and flow to the surroundings, thereby quickly filling the inside of the storage tank and deoxygenating the inside of the storage tank, preventing the powder from contacting with oxygen during storage and causing oxidation. By arranging the air outlet net cylinder inside the storage tank, the nitrogen and the storage material are The contact area of ​​the powder inside the tank is increased, and the deoxygenation efficiency is higher. When nitrogen enters the boost chamber, the piston blocks the outlet of the air chamber, and the nitrogen pressure is insufficient, so it cannot enter the air chamber from the boost chamber and then enter the air outlet net cylinder. When the nitrogen in front is retained in the boost chamber, it is squeezed by the nitrogen continuously injected from the back. After the nitrogen pressure is enhanced, the piston is pushed open and enters the air outlet net cylinder. The air pressure inside the air outlet net cylinder is higher than the external air pressure, and the nitrogen will diverge outward faster, thereby deoxygenating faster, further improving the deoxygenation efficiency.

[0007] According to the above technical scheme, an anti-caking device is arranged on the outside of the air outlet mesh cylinder, and the anti-caking device includes a stirring structure and a vibration structure, and the stirring structure includes a third rotating shaft, a stirring impeller, and a guide plate, and the third rotating shaft is rotatably connected to the bottom end of the storage tank, and the stirring impeller is fixedly connected to the surface of the third rotating shaft, and the guide plate is fixedly connected to the surface of the air outlet mesh cylinder, and the vibration structure includes a vibration plate, a knocking block, a spring piece, and a struck block, and the vibration plate is slidably connected to the bottom of the storage tank, and the knocking block is fixedly connected to the bottom end of the third rotating shaft, and the spring piece is fixedly connected below the vibration plate, and the struck block is fixedly connected to one side of the spring piece, and the third rotating shaft rotates through the bottom surface of the vibration plate, and an arc groove is opened on the inner side of the vibration plate and the boosting chamber is slidably connected to the arc groove, and the nitrogen is blown out from the air outlet mesh cylinder through The guide plate guides the flow, thereby blowing outward at an oblique angle, and generates a driving force when it blows to the blades on the stirring impeller, causing the stirring impeller to rotate. The stirring rotation stirs the powder in the storage tank to prevent the powder from agglomerating and affecting the processing quality. The rotation of the stirring impeller drives the third rotating shaft to rotate, and the third rotating shaft drives the knocking block to rotate. The knocking block knocks the struck block once when it rotates one circle. After the struck block is struck, the spring piece is squeezed. After the spring piece is squeezed, it folds. The elastic effect causes the spring piece to open and recover. The recovery of the spring piece drives the struck block to reset. The struck block vibrates at the moment of reset, driving the vibration plate to vibrate. The vibration of the vibration plate causes the powder to jump. The jumping of the powder will further disperse it and make it more difficult to agglomerate. The position of the powder is displaced when it jumps, so that all the powder can be stirred, the dispersion is made more uniform, and local agglomeration of the powder is avoided, which further improves the processing quality.

[0008] According to the above technical solution, a dehumidification device is arranged on the outside of the vibration plate, and the dehumidification device includes a dehumidification structure and a dehumidification structure, and the dehumidification structure includes a drying box, a top cover, and a sliding cover. The drying box is fixedly connected to the top of the storage tank, the top cover is fixedly connected above the drying box, and the sliding cover is slidably connected to the inner side of the top cover.

The top of the cylinder is rotatably connected, and the fine material channel penetrates into the interior of the outer sleeve. The sliding cover is slid to open the drying box, and the desiccant is placed in the drying box. The desiccant contacts the air inside the storage tank through the mesh holes opened on the bottom of the drying box for dehumidification, which prevents the powder from getting damp and causing inconvenience in processing. Nitrogen enters the drying box through the air vents and contacts the desiccant. The circulation of nitrogen makes the desiccant dissipate more quickly, which improves the dehumidification efficiency of the desiccant. The nitrogen and the desiccant are mixed together to compress the air in the storage tank, so that the moisture attached to the air is squeezed into the outer sleeve through the inner mesh surface, thereby quickly achieving dry and wet separation. After entering the outer sleeve, the nitrogen first occupies the upper half of the outer sleeve, and the moisture density is relatively large. It is compressed downward and condensed, and finally discharged from the dehumidification pipe.

The device performs multi-layer screening on the powder material without affecting the feeding efficiency, thereby improving the screening accuracy and processing efficiency, and making it more convenient to collect the screened coarse material, thereby improving the work efficiency of the staff. The present invention is provided with a boosting chamber, an air outlet net tube, an air chamber, and a pressure piston. When nitrogen enters the boosting chamber, the piston blocks the outlet of the air chamber, and the pressure of the nitrogen is insufficient, so that the nitrogen cannot enter the air chamber from the boosting chamber and then enter the air outlet net tube. When the nitrogen in front is retained in the boosting chamber, it is squeezed by the nitrogen continuously injected in the back. After the nitrogen pressure is enhanced, the piston is pushed open and enters the air outlet net tube. The air pressure inside the air outlet net tube is higher than the external air pressure, and the nitrogen will be dispersed outward faster, thereby deoxygenating faster, further improving the deoxygenation efficiency. The present invention is provided with a vibration plate, a striking block, a spring piece, and a striking block. The striking block generates vibration at the moment of resetting, driving the vibration plate to vibrate. The vibration of the vibration plate causes the powder to jump. The jumping of the powder will further disperse and be more difficult to agglomerate. The position of the powder is replaced when it jumps, so that all the powder can be stirred, the dispersion is more uniform, the local agglomeration of the powder is avoided, and the processing quality is further improved. The present invention is provided with ventilation holes, inner mesh surface, outer sleeve and dehumidification pipe. Nitrogen and desiccant are mixed together to compress the air in the storage tank, so that the moisture attached to the air is squeezed into the outer sleeve through the inner mesh surface, so as to quickly achieve dry and wet separation. After entering the outer sleeve, nitrogen first occupies the upper half of the outer sleeve, and the moisture density is relatively large.

Slide the slide cover 53 to open the drying box 51, and place the desiccant in the drying box 51. The desiccant contacts the air inside the storage tank 1 through the mesh holes on the bottom of the drying box 51 to dehumidify, preventing the powder from getting damp and causing processing inconvenience. Nitrogen enters the drying box 51 through the air vent 54 and contacts the desiccant. The circulation of nitrogen makes the desiccant dissipate more quickly, thereby improving the dehumidification efficiency of the desiccant. The nitrogen and the desiccant are mixed together to compress the air in the storage tank 1, so that the moisture attached to the air is squeezed into the outer sleeve 56 through the inner mesh surface 55, thereby quickly achieving dry-wet separation. After entering the outer sleeve 56, the nitrogen first occupies the upper half of the outer sleeve, and the moisture density is relatively large. It is compressed downward and condensed, and finally discharged from the dehumidification pipe 57. The storage tank 1 is completely dry, so that the powder is stored in a dry environment, which is convenient for later processing.
