[0012] The beneficial effects of this utility model are:

[0013] This application discloses a coking coal screening and feeding system for antimony smelting, comprising a coking coal hopper, a vibrating feeder, a cylindrical screen, a weighing hopper, and a belt conveyor. The vibrating feeder is located at the discharge end of the coking coal hopper. The cylindrical screen is equipped with a cylindrical screen inlet, a coking coal discharge hopper, and a coking coal powder hopper.

Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention. Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0017] like Figure 1 As shown in the figure, this embodiment discloses a coking coal screening and feeding system for antimony smelting, including a coking coal hopper 1, a vibrating feeder 2, a cylindrical screen 4, a weighing hopper 6, and a belt conveyor 7. The vibrating feeder is located at the discharge end of the coking coal hopper. The cylindrical screen is provided with a cylindrical screen inlet 3, a coking coal outlet hopper 5, and a coking coal powder hopper 8. The cylindrical screen inlet is connected to the discharge end of the vibrating feeder. The coking coal outlet hopper is connected to the inlet end of the weighing hopper. The discharge end of the weighing hopper is connected to the inlet end of the belt conveyor.

[0018] During operation, coking coal to be screened flows into the coking coal hopper and is vibrated and fed to the cylindrical screen by the vibrating feeder. The cylindrical screen screens the coking coal, and coking coal of qualified particle size flows into the weighing hopper through the coking coal discharge hopper, while coking coal of unqualified particle size flows into the coking coal powder hopper. The weighing hopper weighs the qualified coking coal, and once the weight is reached, the vibrating feeder and the cylindrical screen stop working. The weighing hopper opens its gate, and the qualified coking coal falls onto the belt conveyor, which then transports it to the smelting furnace for combustion. This cycle is repeated, thus achieving automatic screening and feeding of coking coal into the furnace.

[0019] As a further improvement to the above technical solution, the discharge end of the coking coal powder hopper is equipped with a first ash discharge valve 9; it also includes a coking coal powder storage silo 13, a vacuum cylinder 12, a vacuum blower 11, and a coking coal powder transport truck 17. The inlet end of the vacuum cylinder is connected to the discharge end of the coking coal powder hopper via a pipe 10, and the discharge end of the vacuum cylinder is connected to the inlet end of the coking coal powder storage silo. The vacuum cylinder is evacuated by the vacuum blower. The discharge end of the coking coal powder storage silo is equipped with a second ash discharge valve 16; the coking coal powder storage silo is equipped with a level gauge 14 and an alarm 15. In this embodiment, the first ash discharge valve is a star-shaped feed valve, and the second ash discharge valve is an electric butterfly valve.

[0020] After screening, substandard coking coal powder enters the first ash discharge valve through the coke powder hopper. After being uniformly fed through the first ash discharge valve, the pipeline, under the action of a vacuum fan, creates negative pressure, conveying the substandard coking coal powder to a vacuum cylinder, and then dropping it into the coking coal powder storage silo. The coking coal powder storage silo is equipped with a level gauge. When the coking coal powder in the silo reaches a certain level, an alarm is triggered, and the second ash discharge valve automatically opens to unload the coking coal powder into a coking coal powder transport truck. Once the transport truck is full, the coking coal powder is transported back to the coking coal company.

[0021] As a further improvement to the above technical solution, a controller 18 is also included. The controller is electrically connected to the vibrating feeder, the cylindrical screen, the vacuum fan, and the second ash discharge valve. The controller enables automatic control of the vibrating feeder, the cylindrical screen, the vacuum fan, and the second ash discharge valve.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
