Description

TECHNICAL FIELD

[0001] The utility model relates to coal slime flotation technical field, concretely is a dosing device based on coal slime flotation. BACKGROUND

[0002] Coal slime refers to the semi-solid material formed by coal powder containing water, which is a product in the process of coal production. Its properties differ greatly depending on the variety and formation mechanism. Flotation is a comprehensive process of multiple factors such as coal slime properties, flotation equipment performance, operation system, and process flow. With the increasing complexity of China's coal resources, the development of coal slime flotation technology is particularly important for the development of the coal industry. Flotation process and equipment are the core elements of the coal slime flotation system, which jointly determine product quality and production efficiency.

[0003] The existing dosing device based on coal slime flotation is optimized by increasing the contact area between coal and flotation agent, which improves the flotation efficiency. For example, the Chinese utility model patent with application number CN202322462800.2 discloses a coal slime flotation device. In this device, a bottom plate, support columns, a feed tank, and a flotation cylinder are included. The support columns are fixedly connected to the top left side of the bottom plate at the four corner positions. The feed tank is fixedly connected to the top of the support columns. The flotation cylinder is fixedly connected to the top right side of the bottom plate at the middle position. A crushing mechanism is fixedly connected to the top of the feed tank. This coal slime flotation device starts the crushing motor to drive the disc to rotate, causing the connecting column to deflect. When the connecting column deflects from the highest point of the disc to the lowest point, it exerts pressure on the back-shaped frame, causing the connecting rod to lower the pressing plate. When the connecting column deflects from the lowest point of the disc to the highest point, it causes the back-shaped frame to rise, causing the connecting rod to raise the pressing plate. This allows the pressing plate to crush the coal slime back and forth, thereby increasing the contact area with the flotation agent and improving the flotation efficiency.

[0004] Although the above-mentioned dosing device based on coal slime flotation has certain advantages in increasing the contact area between coal and flotation agent, improving the flotation efficiency, it still has certain disadvantages. During the flotation operation, flotation agent needs to be added to the coal, and the flotation agent cannot be added at once. Usually, personnel add it in small amounts several times. Therefore, personnel need to pay attention to the flotation process during the coal flotation overflow, which cannot be automatically controlled and requires more personnel effort.

[0019] 1. This coal slime flotation dosing device, by setting the control structure below the feed hopper, starts the motor, and the two horizontally arranged rotating parts rotate in different directions. The two adjacent rotating plates cooperate, and the openings formed at the corners have different opening sizes at different positions. This allows the flotation reagent in the feed hopper to fall into the filling chamber and fall according to the size of the opening formed between the two rotating plates. The rotating parts thus control the falling dosage of the flotation reagent. There is no need for personnel to manually control the flotation reagent and pour it into the flotation component in stages, which simplifies the workload of personnel.
