Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to a belt conveyor for steel plants. Background Art

[0002] Belt conveyors are essential conveying equipment widely used in logistics, industry, and other fields. They utilize a continuously moving conveyor belt to transport materials from one location to another, featuring high conveying efficiency, stable operation, and simple operation. A typical belt conveyor consists of a conveyor belt, rollers, supports, and a drive unit, suitable for horizontal or inclined conveying of various bulk materials, granules, or finished products. Belt conveyors can be customized according to actual needs, based on material characteristics, conveying distance, and environmental conditions.

[0003] In existing technologies, such as the Chinese patent with publication number CN215029999U entitled "A Steel Plant Belt Conveyor Material-Iron Separation Device," the disclosed technical solution describes a device equipped with a magnetic permanent magnet drum. When iron slag and waste are conveyed to the upper part of the permanent magnet drum, the iron slag is attracted to the conveyor belt by the permanent magnet drum, while the waste is thrown out by the conveyor belt and falls into the slag discharge port. A scraping mechanism scrapes off the iron slag attracted to the conveyor belt and drops it into the iron discharge port, thereby separating the waste and iron slag and avoiding the discharge of a large amount of iron slag with the waste, thus reducing the waste of iron during the conveying process. However, the waste and iron slag overlap during the conveying process. When the waste and iron slag are conveyed to the upper part of the permanent magnet drum, some waste may be below the iron slag. The iron slag, attracted by the permanent magnet drum, may press this part of the waste onto the conveyor belt, causing this part of the waste to be scraped off along with the iron slag and fall into the iron discharge port. Subsequently, it is necessary to separate the iron slag and this part of the waste. Utility Model Content

[0004] This utility model provides a belt conveyor for steel plants to solve the above-mentioned problems.

[0005] This utility model adopts the following technical solution: a belt conveyor for steel plants, including a frame, a mounting frame, a separation mechanism, and a collection mechanism; multiple idlers are fixedly installed on the frame, and the multiple idlers are arranged between an electric drum and a permanent magnet drum; a support is fixedly installed at the lower end of the frame; an electric drum and a permanent magnet drum are provided on the frame, with the electric drum fixedly installed at one end of the frame; the permanent magnet drum is rotatably installed on the side of the frame away from the electric drum; a conveyor belt is sleeved on the electric drum and the permanent magnet drum; the separation mechanism includes a lifting rod, a lifting plate, a striking rod, and a drive assembly; a mounting frame is fixedly installed on the frame, the lifting rod is slidably installed on the mounting frame, and a lifting plate is fixedly installed at the lower end of the lifting rod. The lowering plate has multiple striking rods fixedly installed at its lower end. The drive assembly is located on the mounting frame and is used to drive the lifting rods up and down. The collection mechanism is located below the frame and is used to collect waste and slag separately. The waste and slag fall onto the conveyor belt, and the electric drum drives the conveyor belt to rotate, carrying the waste and slag to the permanent magnet drum. The drive assembly drives the lifting rods to move up and down, which in turn drives the striking rods to move up and down through the lifting plate. The up and down movement of the lifting rods strikes the conveyor belt, causing the waste and slag to shake on the conveyor belt. Combined with the adsorption effect of the permanent magnet drum, the slag adheres to the surface of the conveyor belt, preventing some of the waste from being pressed onto the conveyor belt by the adsorption of the permanent magnet drum.

[0006] Furthermore, the drive assembly includes a first spring, a motor, a turntable, and a connecting rod; the first spring is sleeved on the lifting rod, with its lower end fixedly connected to the upper end of the mounting bracket, and its upper end fixedly connected to the lifting rod; the motor is fixedly mounted on the upper end of the mounting bracket, and two turntables are provided, located on both sides of the lifting rod, and the turntables are rotatably mounted on the mounting bracket; the turntables are fixedly connected to the motor output shaft; a connecting rod is fixedly installed between the turntables; the motor drives the connecting rod to rotate through the turntables, and under the action of the connecting rod and the first spring, the lifting rod moves up and down, thereby causing the lifting rod to drive the striking rod to move up and down through the lifting plate to strike the conveyor belt.

[0007] Furthermore, the collection mechanism includes a waste bin, an iron slag bin, and a scraping assembly; the iron slag bin is located below the permanent magnet drum, and the waste bin is located on the side of the iron slag bin away from the electric drum; a guide plate is fixedly installed on the side wall of the waste bin near the permanent magnet drum, the guide plate is V-shaped, the end of the guide plate near the permanent magnet drum is the large end, and the end of the guide plate near the waste bin is the small end; the iron slag adheres to the surface of the conveyor belt under the adsorption of the permanent magnet drum, and the waste is thrown out by the conveyor belt and falls into the waste bin through the guide plate.

[0008] Furthermore, the scraping assembly includes a mounting plate and a scraper. The end of the mounting plate away from the electric roller has a sliding groove, in which a guide rod is fixedly installed vertically. A sliding block is fixedly installed on the end face of the scraper near the mounting plate, and the sliding block is slidably installed in the sliding groove. The sliding block and the guide rod are slidably connected. A second spring is sleeved on the guide rod. The upper end of the second spring is fixedly connected to the sliding block, and the lower end of the second spring is fixedly connected to the sliding groove. Under the action of the second spring, the upper end of the scraper abuts against the conveyor belt, and the scraper scrapes off the iron slag that is attracted to the conveyor belt by the permanent magnet roller, so that the iron slag falls into the iron slag box.

[0009] The beneficial effects are: the drive assembly causes the lifting rod to move up and down through the lifting plate to strike the conveyor belt, causing the waste and slag to shake on the conveyor belt. In conjunction with the permanent magnet roller, the slag is attracted and adhered to the surface of the conveyor belt, preventing the slag from pressing some of the waste onto the conveyor belt and causing this waste to fall into the slag box along with the slag.

[0016] like Figure 1-4The following is an embodiment of the belt conveyor for steel plants according to this utility model. The belt conveyor for steel plants includes a frame 100, a mounting frame 150, a separation mechanism, and a collection mechanism. Multiple idlers 120 are fixedly mounted on the frame 100, positioned between an electric drum 110 and a permanent magnet drum 130. A support 160 is fixedly mounted at the lower end of the frame 100. An electric drum 110 and a permanent magnet drum 130 are mounted on the frame 100, with the electric drum 110 fixedly mounted at one end of the frame 100. The permanent magnet drum 130 is rotatably mounted on the side of the frame 100 away from the electric drum 110. A conveyor belt 140 is sleeved on the electric drum 110 and the permanent magnet drum 130. The separation mechanism includes a lifting rod 200, a lifting plate 210, a striking rod 220, and a drive assembly. The mounting frame 150 is fixedly mounted on the frame 100, and the lifting rod 200 is slidably mounted on the mounting frame 150, with the lower end of the lifting rod 200 fixedly mounted on the mounting frame 150. A lifting plate 210 is fixedly installed, and multiple striking rods 220 are fixedly installed at the lower end of the lifting plate 210. A drive assembly is set on the mounting frame 150 and is used to drive the lifting rods 200 to rise and fall. A collection mechanism is set below the frame 100 and is used to collect waste and slag separately. The waste and slag fall onto the conveyor belt 140. The electric drum 110 drives the conveyor belt 140 to rotate and move the waste and slag to the permanent magnet drum 130. The drive assembly drives the lifting rods 200 to move up and down, and through the lifting plate 210, drives the striking rods 220 to move up and down. The up and down movement of the lifting rods 200 strikes the conveyor belt 140, causing the waste and slag to shake on the conveyor belt 140. Combined with the adsorption effect of the permanent magnet drum 130, the slag adheres to the surface of the conveyor belt 140, preventing the slag from pressing some of the waste onto the conveyor belt 140 under the adsorption of the permanent magnet drum 130.

[0017] The drive assembly includes a first spring 201, a motor 230, a turntable 240, and a connecting rod 250. The first spring 201 is sleeved on the lifting rod 200, with its lower end fixedly connected to the upper end of the mounting bracket 150 and its upper end fixedly connected to the lifting rod 200. The motor 230 is fixedly mounted on the upper end of the mounting bracket 150. Two turntables 240 are provided, located on both sides of the lifting rod 200, and are rotatably mounted on the mounting bracket 150. The turntables 240 and the output shaft of the motor 230 are fixedly connected. A connecting rod 250 is fixedly installed between the turntables 240. The motor 230 drives the connecting rod 250 to rotate through the turntables 240, and under the action of the connecting rod 250 and the first spring 201, the lifting rod 200 moves up and down, thereby causing the lifting rod 200 to drive the striking rod 220 to move up and down through the lifting plate 210 to strike the conveyor belt 140.

[0018] The collection mechanism includes a waste bin 300, an iron slag bin 310, and a scraping assembly. The iron slag bin 310 is located below the permanent magnet drum 130, and the waste bin 300 is located on the side of the iron slag bin 310 away from the electric drum 110. A guide plate 301 is fixedly installed on the side wall of the waste bin 300 near the permanent magnet drum 130. The guide plate 301 is V-shaped, with the end of the guide plate 301 near the permanent magnet drum 130 being the large end and the end of the guide plate 301 near the waste bin 300 being the small end. Under the adsorption of the permanent magnet drum 130, the iron slag adheres to the surface of the conveyor belt 140, and the waste is thrown out by the conveyor belt 140 and falls into the waste bin 300 through the guide plate 301.

[0019] The scraping assembly includes a mounting plate 260 and a scraper 270. A sliding groove 261 is provided at the end of the mounting plate 260 away from the electric roller 110. A guide rod 262 is fixedly installed in the sliding groove 261, and the guide rod 262 is vertically positioned. A sliding block 271 is fixedly installed on the end face of the scraper 270 near the mounting plate 260. The sliding block 271 is slidably installed in the sliding groove 261, and the sliding block 271 is slidably connected to the guide rod 262. A second spring 272 is sleeved on the guide rod 262. The upper end of the second spring 272 is fixedly connected to the sliding block 271, and the lower end of the second spring 272 is fixedly connected to the sliding groove 261. Under the action of the second spring 272, the upper end of the scraper 270 abuts against the conveyor belt 140, and the scraper 270 scrapes away the iron slag adsorbed by the permanent magnet roller 130 onto the conveyor belt 140, causing the iron slag to fall into the iron slag box 310.

[0020] Based on the above embodiments, the working principle and process of this utility model are as follows: Waste and slag fall onto the conveyor belt 140. The electric drum 110 drives the conveyor belt 140 to rotate, bringing the waste and slag to the permanent magnet drum 130. The motor 230 drives the connecting rod 250 to rotate through the turntable 240. Under the action of the connecting rod 250 and the first spring 201, the lifting rod 200 moves up and down, thereby causing the lifting rod 200 to drive the striking rod 220 to move up and down through the lifting plate 210 to strike the conveyor belt 140. This causes the waste and slag to shake on the conveyor belt 140. Combined with the adsorption effect of the permanent magnet drum 130, the slag adheres to the surface of the conveyor belt 140, preventing the slag from pressing some of the waste onto the conveyor belt 140 under the adsorption of the permanent magnet drum 130.

[0021] Iron slag adheres to the surface of conveyor belt 140 under the adsorption of permanent magnet drum 130. The waste is thrown out by conveyor belt 140 and falls into waste bin 300 through guide plate 301. Under the action of second spring 272, scraper 270 abuts against conveyor belt 140. Scraper 270 scrapes off the iron slag adsorbed on conveyor belt 140 by permanent magnet drum 130, so that the iron slag falls into iron slag bin 310.

[0022] The above description is merely a specific embodiment of this utility model, and the various examples do not constitute a limitation on the substantive content of this utility model.
