Description

Technical Field

[0001] The present application relates to the technical field of material discharge equipment, and in particular to a mechanical dredging device for a powder ore bin hopper. Background Art

[0002] During mineral processing operations, ore moisture can cause severe blockage in the fine ore bin, significantly impacting throughput, processes, and performance indicators. To stabilize throughput and reduce fluctuations in mineral processing indicators, when ore blockage occurs, crew members are promptly organized to clear the bin. Existing methods typically use bamboo poles and sledgehammers. During bamboo pole clearing operations, there is a risk of injury from the impact of ore on the pole and from falling ore. Using a sledgehammer to strike the ore bucket from a high-altitude edge poses the risk of falling, making clearing the fine ore bin blockage difficult and risky. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related art, the present application provides a mechanical dredging device for the lower hopper of a powder ore bin, which can reduce the difficulty and risk of dredging the powder ore bin due to blockage.

[0004] The present application discloses a mechanical dredging device for the lower hopper of a powder ore bin, comprising: a hopper, the bottom of which is structured with two symmetrical discharge ports; a guide wheel, a steel rope, a winch, a reducer, a motor, and a hook;

[0021] In response to the above problems, an embodiment of the present application provides a mechanical dredging device for the lower hopper of a powder ore bin. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 The mechanical dredging device for the lower hopper of a fine ore silo shown in the figure comprises: a silo 1, the bottom of which is structured with two symmetrical discharge ports 11; a guide wheel 2, a steel rope 3, a winch 4, a reducer 5, a motor 6, and a hook 31;

[0023] The present application suspends two guide wheels 2 above the silo 1. The two guide wheels 2 are mainly used to guide the steel rope 3 so that the steel rope 3 can be pulled easily. To this end, the guide wheels 2 are directly opposite the discharge port 11. The present application changes the traditional discharge port 1 of the silo 1 into two discharge ports, and installs a motor 6 below the discharge port 11 at the bottom of the silo 1. The output end of the motor 6 is connected to the input end of the reducer 5, and the output end of the reducer 5 is connected to the winch 4. The steel rope 3 is connected to one side of the winch 4. In this way, the motor 6 provides power for pulling the steel rope 3, and the reducer 5 adjusts the speed of the motor 6 so that the winch 4 does not rotate too fast. The steel rope 3 passes through the discharge port 11 on one side of the bottom of the silo 1 and passes through the two guide wheels 2. After passing through the discharge port 11 on the other side, it is connected to the winch 4 on the other side. The steel rope 3 is provided with a hook 31, which is located at the discharge port 11.

[0024] In this way, the present application drives the winch 4 through two motors to pull the steel rope 3 to move at the two discharge ports 11. When the steel rope 3 moves back and forth, the hook 31 on the steel rope 3 loosens the material to facilitate the material to fall from the discharge port 11, thereby avoiding blockage of the powder ore bin. In this way, the automatic dredging of the equipment avoids the difficulties and high risks of manual dredging.

[0025] In one embodiment, to facilitate the smooth unloading and conveying of materials, a guide trough 12 is provided at the bottom of the silo 1 below the discharge port 11. The guide trough 12 is configured with a hole for the steel rope 3 to pass through, and the steel rope 3 slides into the hole. The two guide troughs 12 guide the materials to the conveyor belt 7 so that the materials can be conveyed normally.

[0026] In one embodiment, in order to prevent the hook 31 from pressing against the material guide trough 12 during the process of moving the material up and down, a space for the hook 31 to move up and down is provided at the material guide trough 12 .

[0027] In one embodiment, the two discharge ports 11 of the silo 1 are tapered to facilitate material guidance.

[0028] In one embodiment, the hook 31 is configured to be claw-shaped or umbrella-shaped to facilitate loosening of materials.

[0029] In one embodiment, a φ18 steel wire rope is used as the traction rope 3. The rope 3 passes through the ore in the fine ore bin, with claw- or umbrella-shaped hooks 31 installed every 10 cm. Two sets of motor 6 and reducer 5 are configured: XWD6-87-3KW, with a transmission ratio of 87, a center height of 200 mm, an input power of 3KW, 380V, and a frequency converter of 50 Hz. The guide pulley 2 is a ZDY series mining overhead sheave with a diameter of 1 meter and a rated load of ≥5 tons. The motor is controlled by an ACS880-01-045A-3 inverter.

[0030] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
