[0002] Coal powder refers to coal with a particle size of less than 0.5 mm, and is the most commonly used additive in cast iron sand. In recent years, foreign countries have mixed coal powder with clay to form a commodity (carbon clay) for the market. Coal powder metering scale is an instrument for measuring the flow of coal powder, which is widely used in industrial fields such as coal-fired power generation and steel smelting. When putting coal powder into the coal powder metering scale, a flow stabilizing mechanism is needed to assist to prevent the coal powder from agglomerating.

[0003] The prior art has the following deficiencies: the prior art "a coal powder conveying steady flow system" with the publication number CN213955360U "includes a coal powder bin and a coal powder scale, and also includes a feed assembly, an upper pneumatic gate valve, an intermediate bin, a lower pneumatic gate valve and a sensor assembly. A feed assembly and an intermediate bin are provided between the coal powder bin and the coal powder scale. An upper pneumatic gate valve is provided at the connection between the feed end of the feed assembly and the coal powder bin, and the discharge end of the feed assembly is connected to the intermediate bin. A lower pneumatic gate valve is provided at the discharge end of the intermediate bin; a sensor assembly for measuring the weight of the material entering the intermediate bin is provided on the upper outer side of the intermediate bin";

However, the structure is complex as a whole, with many internal structures, and the stabilization process of coal powder is relatively cumbersome. It cannot solve the problem of coal powder agglomerating and surging.

[0005] The prior art has the following problems:

[0006] The current coal powder metering auxiliary flow stabilization equipment has a complex structure and a cumbersome flow stabilization process, and is unable to cope with problems such as coal powder agglomeration. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a coal powder metering scale auxiliary flow stabilizing device, which solves the current problems.

The motor is fixedly connected to the lower end of the material leveling plate and the inner wall of the motor cover. The shaft column is movably connected to the top end face of the motor. The spoiler is designed in an arc-shaped blade style, equidistantly distributed on the outer end of the shaft column and establishes a fixed connection relationship.

[0011] As a preferred technical solution of the utility model, the lower barrel also includes a lower hopper and a grid. The lower hopper opening is fixedly connected upward to the top of the lower barrel and is internally connected. The grid is a combination of multiple strip structures arranged equidistantly, with equidistant gaps in the middle.

[0012] As a preferred technical solution of the utility model, the middle part of the material leveling plate is higher than the peripheral disc-shaped structure, the through groove is opened at the highest point of the material leveling plate, and the bottom end of the material leveling plate is an inverted bucket-shaped structure.

[0013] As a preferred technical solution of the utility model, the connecting bracket is an arc-shaped strip structure, and is provided with four groups, all of which are expanded outward and serve as a connecting and fixing structure between the discharge barrel and the material leveling plate.

[0014] As a preferred technical solution of the utility model, the connection position between the motor and the shaft column passes through the through-slot structure of the material leveling plate, and the baffles are provided in six groups and are arranged separately on both sides.

[0015] As a preferred technical solution of the utility model, the flow stabilizing mechanism needs to establish a connection with an external control unit before use, and the discharge barrel needs to be installed directly above the external coal powder metering scale.

[0016] As a preferred technical solution of the utility model, the rotation speed of the spoiler is positively correlated with the operating power of the motor, and the motor can be adjusted and controlled by an external control unit. The rotation speed of the spoiler directly affects the falling trajectory and speed of the coal powder.

[0018] The auxiliary flow stabilizing device for coal powder metering scale is provided with a grid, a flow stabilizing mechanism, a motor, a shaft column and a baffle plate. When the device is ready for operation, the device needs to be set just above the coal powder metering scale, and then the motor is started through an external control structure. The motor drives the shaft column to rotate and drives the baffle plate to rotate. When the coal powder is put into the lower hopper, the grid will crush the falling coal powder through collision. After passing through the lower hopper, the coal powder will slowly descend in a step-by-step manner under the obstruction of the multi-layer baffle plate, and finally fall on the material leveling plate at the bottom. The coal powder is evenly dispersed to the surroundings on the material leveling plate, and finally falls on the coal powder metering scale. The above-mentioned setting enables the device to crush the coal powder when the coal powder is discharged. At the same time, the baffle plate can block the coal powder at a suitable speed in the lower barrel by adjusting the motor operating power, limit the coal powder falling speed, play a better flow stabilizing effect, prevent the coal powder from agglomerating, clumping, and upwelling, and the overall structure is simple and compact.
