Description

Technical Field

[0001] This utility model belongs to the field of material feeding and conveying technology, and in particular relates to a material feeding device for an ore dryer. Background Technology

[0002] After mining, ore needs to be dried to reduce its weight and transportation costs, and to prevent the damp ore from freezing into lumps in cold weather, which would cause significant difficulties for unloading and subsequent processing. When the dried ore is fed into the mill, it contains a large amount of ore powder, which disperses during the feeding process, impacting the environment. Furthermore, the ore powder still contains ore components, and direct dispersion results in losses. Additionally, the dried ore requires grinding; when ore powder is fed into a crusher or ball mill along with the ore, the fine powder occupies equipment space, absorbs impact energy, and buffers the effective impact and grinding of coarse particles by the grinding media. This not only reduces grinding efficiency but also causes secondary over-grinding of the fine powder, producing more difficult-to-process ultrafine particles, wasting energy and increasing the difficulty of subsequent sorting.

[0003] To address these issues, we provide a feeding device for an ore dryer. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for an ore dryer. A guide pipe is installed on the connecting cover of the feeding hopper, and the other end of the guide pipe is connected to a dust collection hopper. A feeding port is provided on the connecting cover. The dried ore is poured into the feeding hopper through the feeding port, causing the powder in the ore to be lifted and enter the dust collection hopper along the guide pipe, thereby achieving the separation of ore blocks and ore powder. An adsorption pipe is installed at the lower end of the dust collection hopper, and a discharge ring grid is installed inside the dust collection hopper. A current opposite to that of the discharge ring grid is passed through the adsorption pipe. When the ore powder enters the dust collection hopper, it passes through the discharge ring grid, causing the ore powder to become charged. When the ore powder enters the adsorption pipe, the charged ore powder is adsorbed onto the pipe wall of the adsorption pipe under the action of the charge, preventing the ore powder from scattering.

A feeding port 101a is provided on the connecting cover 101. The dried ore is poured from the feeding port 101a into the feeding hopper 1, causing the powder in the ore to be lifted and flow along the guide pipe 101b. 01b enters the dust collection funnel 2, thereby achieving the separation of ore blocks and ore powder; by setting an adsorption tube 4 at the lower end of the dust collection funnel 2 and setting a discharge ring grid 3 inside the dust collection funnel 2, the adsorption tube 4 is passed with a current opposite to that of the discharge ring grid 3. When the ore powder enters the dust collection funnel 2, it passes through the discharge ring grid 3 and becomes charged.

[0016] Specifically, the upper end of the feeding funnel 1 is fixedly covered with a connecting cover 101, and the upper end of the connecting cover 101 is provided with a feeding port 101a. The upper opening of the dust collecting funnel 2 is fixedly provided with a dust cover 201. The upper end of the connecting cover 101 is connected to a drain pipe 101b.

The discharge ring grid 3 is fixedly installed in the dust collecting funnel 2, and the adsorption tube 4 is fixedly installed at the lower opening of the dust collecting funnel 2.

[0017] Furthermore, a screw tube 102 is fixedly installed at the lower end of the feeding hopper 1. A discharge port 102a is provided on the lower side wall of the screw tube 102. The lower end of the screw tube 102 is closed. An auger screw 102b is rotatably installed inside the screw tube 102. The lower rotating shaft of the auger screw 102b passes through the lower end of the screw tube 102 and is connected to the output shaft of the motor. When the ore is fed, it falls into the feeding hopper 1 and is conveyed downward by the auger screw 102b, thereby preventing the ore powder from scattering.

[0018] Furthermore, a fan channel 103 is provided on the side wall of the feeding hopper 1, and a dust-raising fan 103a is provided in the fan channel 103. The dust-raising fan 103a blows up the powder in the ore, thereby separating the ore from the powder.

[0019] The operation process in this embodiment is as follows: The dried ore is poured from the discharge port 101a into the discharge hopper 1. The dust fan 103a blows up the powder in the ore, thereby separating the ore from the powder. When the ore is discharged, it falls into the discharge hopper 1 and is conveyed downward by the screw 102b to prevent the ore powder from scattering. Example 2

[0020] Please see Figures 1 to 5 Based on Example 1, a dust removal tube 401 is fixedly installed at the lower end of the adsorption tube 4. By vertically sliding the dust scraper 402 inside the adsorption tube 4, the dust scraper 402 slides up and down in the adsorption tube 4, scraping the ore powder adsorbed in the adsorption tube 402 toward the dust removal tube 401, so that the ore powder detaches from the tube wall and falls at the uncharged dust removal tube 401.

[0021] Specifically, the drainage pipe 101b consists of two pipe sections, and a drainage fan 101b-1 is installed in the pipe section where the two ends of the drainage pipe 101b meet.

[0022] Furthermore, the lower end of the dust removal pipe 401 is closed, and a powder outlet 401a is provided on the lower side wall of the dust removal pipe 401. The ore powder that has been removed from the adsorption pipe 4 is discharged from the powder outlet 401a.

[0023] Furthermore, a dust scraper sleeve 402 is vertically slidably sleeved inside the adsorption tube 4. A set of connecting arms 402a is fixedly arranged in a circumferential array on the inner hoop surface of the dust scraper sleeve 402. A pull rod 402a-1 is fixedly arranged at one end of the set of connecting arms 402a away from the dust scraper sleeve 402. The pull rod 402a-1 extends downward and passes through the closed end of the dust removal tube 401.

[0024] Furthermore, a cylinder 402a-2 is provided at the lower end of the dust removal pipe 401. The telescopic end of the cylinder 402a-2 is connected to the pull rod 402a-1. The telescopic end of the cylinder 402a-2 pushes the pull rod 402a-1 to move up and down, thereby causing the dust scraper sleeve 402 to scrape off the ore powder adsorbed in the adsorption pipe 4.

[0025] The operation process in this embodiment is as follows: The induced draft fan 101b-1 blows the ore dust raised by the dust-generating fan 103a into the dust collection funnel 2, and applies a current opposite to that of the discharge ring grid 3 to the adsorption tube 4. When the ore powder enters the dust collection funnel 2, it passes through the discharge ring grid 3 and becomes charged. When the ore powder enters the adsorption tube 4, the charged ore powder is adsorbed onto the tube wall of the adsorption tube 4 under the action of the charge, preventing the ore powder from scattering. The telescopic end of the cylinder 402a-2 pushes the pull rod 402a-1 to move up and down, thereby causing the dust scraper 402 to scrape the ore powder adsorbed in the adsorption tube 4 into the dust removal tube 401, so that the ore powder detaches from the tube wall at the uncharged dust removal tube 401 and is discharged from the powder outlet 401a.
