Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for processing scrap metals. Background Art

[0002] After recycling, scrap metal will contain other materials on its surface, so it needs to be processed through batch crushing, screening, smelting and other processing steps so that the scrap metal can be used again.

[0003] During the processing, a conveying device is needed to load the materials. The loading device used for transmission is usually a conveyor belt. The materials are transported from one end of the conveyor belt to the other end, and then fall into the processing equipment.

[0004] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and have not been well solved: after the scrap metal is recycled, it is not in a clean state, and almost all of its surfaces contain a large amount of rust. When a large number of scrap metals fall on the conveying and feeding device in turn, the dust, rust ash and rust residue on its surface will fall off due to the collision between the materials and the conveyor belt, and splash will occur, causing very serious pollution to the air near the conveying and feeding device, and will also affect the health of nearby workers. Utility Model Content

[0005] The main purpose of the utility model is to provide a scrap metal processing feeding device, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A scrap metal processing feeding device comprises a conveying frame, a conveying device is installed on the conveying frame, a processing box is arranged above the conveying device, an air suction groove is bored at one end of the processing box, a mounting groove is bored at the top of the processing box, an exhaust pipe is arranged outside the processing box at the position of the air suction groove, an air guide pipe is fixed to one end of the exhaust pipe close to the processing box, a fixing frame is installed at one end of the exhaust pipe away from the air guide pipe, a fan assembly is installed at one end of the exhaust pipe close to the processing box, a driving motor is installed on the fixing frame, a mounting plate is arranged on the mounting groove, a connecting frame is fixed to the bottom of the mounting plate, an inner cover is fixed to the bottom of the connecting frame, and a plurality of electromagnets are installed inside the inner cover.

[0008] Preferably, the drive motor is electrically connected to the fan assembly.

[0009] Preferably, a flange is provided at one end of the air duct close to the processing box, and a plurality of bolts are inserted into the mounting plate, the flange and the side walls at both ends of the bottom of the processing box. The flange is detachably connected to the processing box by bolts, the processing box is detachably connected to the conveying rack by bolts, and the mounting plate is detachably connected to the processing box by bolts.

[0010] Preferably, the inner diameters of the inner cover and the flange at one end close to each other respectively match the inner diameters of the air suction groove, and the positions of the three match.

[0011] Preferably, the inner diameter of the inner cover at one end away from the air suction groove is larger than the inner diameter of the air suction groove.

[0012] Preferably, a feed hopper is fixed to one end of the processing box away from the discharge pipe, and a feed trough is excavated at a position at one end of the bottom of the feed hopper of the processing box, and the inner size of the feed trough matches the inner size of the end close to the feed hopper.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The material enters the processing box from the inlet of the processing box, and generates a large amount of dust particles when it touches the surface of the conveyor device, which contains a large amount of rust, dust, and rust residue. At this time, the driving motor drives the fan assembly to start rotating after working, which can suck the dust particles out of the inside of the processing box and filter them through the filter device connected to one end of the exhaust pipe away from the processing box. This method can avoid the hidden danger of causing damage to the environment and staff, and has a better protective effect.

[0015] 2. When dust particles enter the air duct from the processing box, they need to pass through the inner cover first. The electromagnet in the inner cover can generate magnetic attraction, which can absorb rust or other small metal impurities in the dust particles to prevent them from entering the filter equipment and causing filtering burden on the filtering equipment;

[0016] When the bolts on the mounting plate are removed, it can be separated from the processing box, and the mounting plate can be lifted up through the connecting frame, driving the inner cover to be pulled out from the mounting slot of the processing box, so that the metal impurities adsorbed on the electromagnet can be removed to ensure the accuracy of subsequent adsorption.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, a scrap metal processing feeding device comprises a conveying frame 1, on which a conveying device 2 is installed, a processing box 3 is arranged above the conveying device 2, an air suction groove 31 is cut at one end of the processing box 3, a mounting groove 32 is cut at the top of the processing box 3, an exhaust pipe 5 is arranged outside the processing box 3 at the position of the air suction groove 31, an air guide pipe 51 is fixed at one end of the exhaust pipe 5 close to the processing box 3, a fixing frame 53 is installed at one end of the exhaust pipe 5 away from the air guide pipe 51, a fan assembly 55 is installed at one end of the exhaust pipe 5 close to the processing box 3, a driving motor 54 is installed on the fixing frame 53, a mounting plate 6 is arranged on the mounting groove 32, a connecting frame 61 is fixed at the bottom of the mounting plate 6, an inner cover 62 is fixed at the bottom of the connecting frame 61, and a plurality of electromagnets 63 are installed inside the inner cover 62.

[0024] Specifically, the driving motor 54 is electrically connected to the fan assembly 55 .

[0025] Specifically, a flange 52 is provided at one end of the air duct 51 close to the processing box 3, and a plurality of bolts 7 are inserted into the mounting plate 6, the flange 52 and the side walls at both ends of the bottom of the processing box 3. The flange 52 is detachably connected to the processing box 3 by the bolts 7, the processing box 3 is detachably connected to the conveying rack 1 by the bolts 7, and the mounting plate 6 is detachably connected to the processing box 3 by the bolts 7, so as to facilitate disassembly and assembly.

[0026] Specifically, the inner diameters of the inner cover 62 and the flange 52 at one end thereof respectively match the inner diameters of the air suction slot 31 , and the positions of the three match to facilitate unified discharge.

[0027] Specifically, the inner diameter of the inner cover 62 at one end away from the air suction groove 31 is larger than the inner diameter of the air suction groove 31, thereby achieving an expansion effect.

[0028] Specifically, a feed hopper 4 is fixed to one end of the processing box 3 away from the discharge pipe 5, and a feed trough is excavated at a position at one end of the bottom of the feed hopper 4 of the processing box 3. The inner size of the feed trough matches the inner size of the end close to the feed hopper 4, which is convenient for accurately unloading materials onto the conveying rack 1, so that the conveying rack 1 can be loaded with materials, and it is also convenient to remove dust when the materials fall onto the conveying rack 1.

[0029] Working principle: the material enters the processing box 3 from the feeding port of the processing box 3, and generates a large amount of dust particles when it touches the surface of the conveying device 2, which contains a large amount of rust, dust, and rust residue. At this time, the driving motor 54 drives the fan assembly 55 to start rotating after working, which can suck out the dust particles from the inside of the processing box 3 and filter them through the filter device connected to the end of the exhaust pipe 5 away from the processing box 3. This method can avoid the hidden danger of causing damage to the environment and staff, and has a good protective effect. The filtering device proposed in this application is a prior art, and its structure and operation principle are no longer explained in this application. When the dust particles enter the air guide pipe 51 from the processing box 3, they need to pass through the inner cover 62 first. The operation of the electromagnet 63 in the inner cover 62 can generate magnetic attraction.

When the bolts 7 on the mounting plate 6 are removed, it can be separated from the processing box 3, and the mounting plate 6 can be lifted through the connecting frame 61. The inner cover 62 is driven to be pulled out from the mounting slot 32 of the processing box 3, so that the metal impurities adsorbed on the electromagnet 63 can be removed to ensure the accuracy of subsequent adsorption;
