Description

Technical Field

[0001] The utility model relates to the field of cold spraying, in particular to a powder material storage device for cold spraying. Background Art

[0002] Cold spraying is a metal and ceramic spraying process, but it is different from traditional thermal spraying (super-velocity flame spraying, plasma spraying, explosion spraying and other traditional thermal spraying). It does not need to melt the sprayed metal particles, so the temperature generated on the surface of the sprayed substrate will not exceed 150 degrees Celsius. At the same time, the sintering temperature of ceramics is above 1500 degrees Celsius, so cold spraying can spray ceramic coatings (such as alumina) on almost all substrates, but if the metal particles do not reach supersonic speed, they cannot adhere. Storage devices are used when storing cold sprayed powder materials.

[0003] However, in the prior art, due to long-term storage, the powder coating may form lumps due to pressure in the storage device, which undoubtedly affects the quality of the powder coating. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a powder material storage device for cold spraying, comprising a storage cylinder, a cylinder cover is provided at the upper end of the storage cylinder, the upper end of the cylinder cover is fixedly connected to a connecting box, a guide groove is opened on the inner wall of the connecting box, a guide block is slidably connected inside the guide groove, one side of the guide block is fixedly connected to a gear plate, an electric push rod is provided on the front side of the gear plate, a rotating shaft is provided inside the cylinder cover, the upper end of the rotating shaft is fixedly connected to the rotating shaft, the upper end of the rotating shaft is fixedly connected to a gear, the lower end of the rotating shaft is fixedly connected to a stirring rod, the lower end of the storage cylinder is fixedly connected to a discharge pipe, and a control valve is provided inside the discharge pipe.

[0006] Preferably, both sides of the storage cylinder are fixedly connected with an air inlet pipe, the other end of the air inlet pipe is fixedly connected with a connecting seat, the left and right sides of the connecting seat are fixedly connected with fixing seats, a drying plate is arranged inside the connecting seat, both sides of the drying plate are fixedly connected with mounting rods, and a card hole is opened inside the mounting rod.

[0009] Preferably, the number of the mounting rods is two groups, and they are symmetrically arranged about the center line of the drying plate.

[0010] Preferably, the push block slides in the adjustment slot via a spring.

[0011] By adopting the above technical solution, the electric push rod is started, which causes the gear plate to move laterally. This movement causes the gear to rotate, thereby driving the rotating shaft and the stirring rod to rotate. The stirring rod stirs the powder material in the storage cylinder. During this process, the guide block slides in the guide groove to ensure the stability of the movement of the gear plate. The stirring rod can be rotated in the storage cylinder through the gears, gear plate, electric push rod, etc., thereby achieving stirring of the powder material, avoiding the problem of powder coating being pressed into blocks during long-term storage, and at the same time ensuring the quality of the powder coating.

[0012] By adopting the above technical solution, the push block is pushed to one side, the push block compresses the spring, the clamping rod slides out from the inside of the clamping hole, and the drying plate is pulled. The drying plate drives the mounting rod to slide inside the mounting groove, and the removal of the drying plate is completed. Similarly, during installation, the mounting rod is slid into the inside of the mounting groove, and the spring rebounds and pushes the push block to slide to one side, thereby making the clamping rod enter the inside of the clamping hole to complete the fixation of the mounting rod, that is, the installation of the drying plate is realized. The drying plate can be loaded and unloaded by the spring, the push block, the clamping rod, the mounting rod and the clamping hole inside it, and can be replaced after long-term use. At the same time, the setting of the drying plate ensures that the air entering the storage cylinder remains dry, which helps to improve the dryness of the powder material in the storage cylinder.
