This device is commonly used in the fields of chemistry, metallurgy, steel, casting, surface treatment, and some special industrial processes for the purposes of refining, deoxidation, impurity removal, surface coating, etc.

[0003] In the metallurgical and steel production, the refining agent powder spraying device can be used for deoxidation, desulfurization and other steps in the refining process. The refining agent is usually some chemical substances containing oxides, lime, chlorides, etc. Through the powder spraying device, these refining agents are uniformly sprayed onto the surface of molten metal to help remove impurities in the metal and improve the quality and performance of the metal. In some applications, the refining agent powder spraying device is used for coating the surface of metals or other materials. For example, some high-temperature-resistant and corrosion-resistant chemical powders are sprayed to form a protective layer to prolong the service life of the material. This technology is commonly used in the casting, steel industry and other scenarios that require corrosion prevention or wear resistance. In the casting process, the refining agent powder spraying device can uniformly spray the refining agent in powder form onto the surface of the casting mold to achieve the effects of reducing oxidation, removing impurities, and improving the surface quality of the casting. Through the action of the refining agent, the metal fluidity and forming quality in the casting process are improved.

[0004] The refining agent powder spraying device plays a crucial role in multiple industrial fields, helping to achieve refining, surface treatment, reaction catalysis, and other goals, and improving production efficiency and product quality. However, the existing refining agent powder spraying device has the following problems in actual application:

[0005] 1. When spraying powder on the workpiece, the workpiece remains stationary, and only the angle of the spray head is adjusted to spray powder on the workpiece, resulting in poor uniformity of the workpiece receiving powder.

[0006] 2. During the powder spraying process, the refining agent is carried by the inert gas flow and sprayed onto the workpiece. The classification and recovery of the residual refining agent and inert gas after powder spraying is a difficult problem to handle. INVENTION CONTENTS

[0009] The inside of the powder spraying box is fixedly connected with a partition plate, the middle part of the partition plate is rotatably connected with a rotating disc, the edge top of the rotating disc is fixedly connected with a pushing rod, a driving mechanism is arranged below the rotating disc for driving the rotating disc to rotate, and the top end of the pushing rod pushes the screen when the rotating disc rotates.

[0010] As a preferred solution of the above technical solution, the front of the powder spraying box is provided with a box door.

[0011] As a preferred solution of the above technical solution, the Y-shaped three-way pipe comprises a collecting pipe, an air inlet end and a material inlet end.

[0012] The collecting pipe is connected with the side of the powder spraying box and faces the upper part of the rotating disc.

[0013] The air inlet end and the material inlet end are respectively connected with an external air inlet assembly and a feeding assembly.

[0014] As a preferred solution of the above technical solution, the end of the gas collecting pipe away from the outer cover is connected with an external gas recovery assembly.

[0015] As a preferred solution of the above technical solution, the top of the rotating disc is detachably provided with a positioning block, and the positioning block is fixed on the top of the rotating disc through bolts.

[0016] As a preferred solution of the above technical solution, the driving mechanism comprises a servo motor fixedly installed on the inner wall of the bottom of the powder spraying box, the output shaft of the servo motor is fixedly connected with a rotating shaft, and the top end of the rotating shaft is fixed with the bottom center of the rotating disc.

[0017] The beneficial effects of the present application are as follows:

[0018] 1. When the present application is in operation, the workpiece to be sprayed is placed on the top center of the rotating disc, and then the rotating disc and the workpiece on the top thereof can be driven to rotate under the driving of the driving mechanism. At this time, the refining agent is sprayed on the workpiece along with the inert gas from the Y-shaped three-way pipe. Since the workpiece is in a state of continuous rotation, the refining agent can be more uniformly sprayed on the workpiece, and the powder spraying effect is better.

[0019] 2. The present application can separate the excess refining agent and inert gas through the screen. The screen is first installed in an inclined manner at the corner position of the top and both sides of the powder spraying box.
