Description

Technical Field

[0001] The utility model relates to the technical field of RDF fuel rod production, in particular to an RDF fuel rod raw material iron remover. Background Art

[0002] RDF fuel rod is a fuel rod made from a mixture of solid waste and recyclable materials. RDF fuel rod is usually made from a mixture of daily raw materials, waste paper, waste plastic and waste wood. After treatment and processing, it becomes solid fuel to replace traditional fossil fuels such as coal and oil.

[0003] During the production and processing of RDF fuel rods, the collected raw materials must first be processed to remove iron filings from the raw materials. For example, a concrete expansion agent raw material iron removal device disclosed in Chinese patent CN211613060U has a magnet disposed inside the conveyor belt and a magnet disposed inside the driven wheel, so that when the material falls on the conveyor belt, the iron filings cannot be driven to fall together, so that the iron filings can stick to the conveyor belt, and then the iron filings are removed by the shovel head, so that the device can run all the time, thereby improving production efficiency. However, when the raw materials enter the conveyor belt from the discharge port of the grinding device for iron removal, the raw materials are easily accumulated on the conveyor belt, and the iron filings in the raw materials cannot be completely removed. Therefore, we propose an RDF fuel rod raw material iron removal machine. Utility Model Content

[0004] The utility model aims to provide an RDF fuel rod raw material iron removal machine, which has the function of automatic material turning so as to achieve a more thorough iron removal effect.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an RDF fuel rod raw material iron remover, comprising two supporting side plates, a conveying assembly installed on the supporting side plates, an adsorption assembly installed between the two supporting side plates and located on the inner side of the conveying assembly, a scraper installed between the two supporting side plates and in contact with the outer side of the conveying assembly, and a material box installed between the supporting side plates, a hopper is installed inside the material box, the bottom of the hopper is connected to a discharge pipe with one end extending above the conveying assembly, a spacing discharge assembly is provided in the discharge pipe, a movable plate located above the conveying assembly is movably installed between the two supporting side plates, a toothed plate is fixedly installed at the bottom of the movable plate, a driving assembly for driving the movable plate to reciprocate is also provided between the two supporting side plates, and a belt is connected to the driving assembly and the spacing discharge assembly.

[0006] By adopting the above technical solution, the raw materials to be processed fall into the conveying assembly through the discharge pipe and are continuously conveyed forward. During the conveying process, the adsorption assembly adsorbs the iron filings in the raw materials. The driving assembly starts to make the movable plate drive the toothed plate to continuously spread the raw materials falling on the conveying assembly, so that the debris in the raw materials will not be piled up together, and can be better adsorbed by the adsorption assembly, and the iron removal is more thorough. When driving the movable plate to move, the driving assembly also uses the belt to drive the interval discharge assembly to rotate, so that the raw materials in the hopper can be discharged at intervals and fall on the conveying assembly, avoiding too much material discharge at one time affecting the iron removal effect, and finally fall on the conveying assembly.

[0007] The iron filings on the parts can be scraped off by the scraper.

[0008] The utility model is further configured as follows: the conveying assembly includes a conveying roller rotatably connected between the two supporting side plates, a conveying belt drivingly connecting the two conveying rollers, and a conveying motor installed on one of the supporting side plates for driving one of the conveying rollers to rotate.

[0010] The utility model is further configured as follows: the adsorption assembly comprises a connecting transverse plate installed between the two supporting side plates and located on the inner side of the conveyor belt, and a magnetic adsorption plate installed on the connecting transverse plate.

[0011] By adopting the above technical solution, when the conveyor belt transports the raw materials to be processed to the top of the magnetic adsorption plate, the magnetic adsorption plate firmly adsorbs the iron filings on the upper surface of the conveyor belt. When the adsorbed iron filings are transported to a position without a magnetic adsorption plate, the iron filings are scraped off by the scraper.

[0012] The utility model is further configured as follows: the number of the toothed plates is no less than ten and they are distributed at equal distances in the transverse direction.

[0013] By adopting the above technical solution, the raw materials falling on the conveyor belt can be continuously spread evenly, thereby improving the iron removal effect.

[0014] The utility model is further configured as follows: movable grooves for the movable plate to move are provided on opposite sides of the two supporting side plates, and the inner walls of the movable grooves are smooth.

[0015] By adopting the above technical solution, the resistance generated by the movement of the movable plate is reduced, the movable plate moves more smoothly, and the friction loss is reduced.

[0016] The utility model is further configured as follows: the driving assembly includes a servo motor installed on one of the supporting side plates, a rotating rod fixedly connected to the output shaft of the servo motor and rotatably connected to the other supporting side plate, and a gear installed outside the rotating rod.

[0017] The utility model is further configured as follows: the driving assembly further comprises a tooth groove provided on the movable plate, and the gear is meshed with the movable plate through the tooth groove.

[0018] By adopting the above technical solution, the servo motor starts to drive the gear on the rotating rod to rotate. When the gear rotates, it pushes the toothed plate on the movable plate to move left and right above the conveyor belt, and the raw materials falling on the conveyor belt are continuously spread evenly, thereby improving the iron removal effect.

[0019] The utility model is further configured as follows: the spacer discharge assembly comprises a connecting shaft penetrating through the inner wall of the discharge pipe and rotatably connected thereto, and a guide plate installed outside the connecting shaft.

[0020] The utility model is further configured as follows: the belt transmission connects the connecting shaft and the rotating rod.

[0021] By adopting the above technical solution, when the servo motor starts to drive the rotating rod to rotate, the rotating rod drives the connecting shaft to rotate through the belt, and then drives the guide plate to rotate inside the discharge pipe, so that the raw materials in the hopper can be discharged at intervals and fall onto the conveyor belt, avoiding too much material being discharged at one time and affecting the iron removal effect.

[0022] The utility model is further configured as follows: the hopper is connected to a feed pipe with one end extending to the top of the material box, and the bottom of the hopper is designed with a constricted opening.

[0023] By adopting the above technical solution, the feed pipe makes it convenient to add raw materials into the hopper, and the necking design makes it convenient for the raw materials to flow out.

[0024] The beneficial effects of the utility model are as follows: the raw materials to be processed fall through the discharge pipe into the conveying assembly and are continuously conveyed forward; during the conveying process, the adsorption assembly adsorbs iron filings in the raw materials; the driving assembly starts to cause the movable plate to drive the toothed plate to continuously spread the raw materials falling on the conveying assembly, so that the debris in the raw materials will not pile up together and can be better adsorbed by the adsorption assembly, and the iron removal is more thorough; when driving the movable plate to move, the driving assembly also uses a belt to drive the interval discharge assembly to rotate, so that the raw materials in the hopper can be discharged at intervals and fall on the conveying assembly, avoiding excessive discharge at one time that affects the iron removal effect.

[0031] The raw materials to be processed fall on the conveying assembly through the discharge pipe 10 and are continuously conveyed forward. During the conveying process, the adsorption assembly adsorbs the iron filings in the raw materials. The driving assembly starts to make the movable plate 11 drive the toothed plate 12 to continuously spread the raw materials falling on the conveying assembly, so that the debris in the raw materials will not pile up together, and can be better adsorbed by the adsorption assembly, and the iron removal is more thorough. When driving the movable plate 11 to move, the driving assembly also uses the belt 18 to drive the interval discharge assembly to rotate, so that the raw materials in the hopper 9 can be discharged at intervals and fall on the conveying assembly, avoiding too much material discharge at one time affecting the iron removal effect. Finally, the iron filings falling on the conveying assembly can be scraped off by the scraper 7.

[0033] The adsorption component includes a connecting transverse plate 5 installed between the two supporting side plates 1 and located on the inner side of the conveyor belt 4, and a magnetic adsorption plate 6 installed on the connecting transverse plate 5. When the conveyor belt 3 transports the raw materials to be processed to the top of the magnetic adsorption plate 6, the magnetic adsorption plate 6 firmly adsorbs the iron filings on the upper surface of the conveyor belt 3.

[0035] The opposite sides of the two supporting side plates 1 are provided with movable grooves for the movable plate 11 to move.
