Description

Technical Field

[0001] The utility model relates to the technical field of powder processing, in particular to an inlet impurity removal structure. Background Art

[0002] Powders generally refer to solid materials with relatively small particle diameters. Usually, they are fine particles obtained by grinding, crushing hard substances or chemical reactions. Powder raw materials are required in aspects such as paint production, and various substances are produced through the processing of powder raw materials.

[0003] The existing powder processing feeding mechanism has the following drawbacks when in use: Before the powder is input into the production equipment for production, generally, an impurity removal and filtering component needs to be installed at the feeding end to remove impurities from the powder raw materials to be used, and metal impurity particles mixed in the grinding process and other process are removed. The existing filtering method usually directly uses a magnetic roller for adsorption. In the actual use process, especially during high-speed feeding, the feeding rate of the powder is relatively large, resulting in the impact force during the powder feeding process being likely to wash off the metal impurities adsorbed on the surface of the magnetic roller into the production equipment, affecting the quality of impurity removal and filtering. Therefore, we propose an inlet impurity removal structure. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an inlet impurity removal structure. Through the feeding mechanism arranged inside the hopper, the powder can be removed from impurities quickly and conveniently, and the adsorbed metal impurities can be prevented from being mixed into the powder again, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An inlet impurity removal structure includes a hopper and also includes a feeding mechanism. The feeding mechanism is arranged inside the hopper. The feeding mechanism includes a silo, a magnetic roller, a square bellows, a discharge pipe, a mounting cover, a motor A, a lead screw, a ball nut, a transmission rod and a scraping ring. A silo is arranged at the bottom of the hopper, and a magnetic roller corresponding to the position is installed inside the silo. The discharge end of the hopper is movably connected with a discharge pipe through a square bellows. The power end of the motor A is provided with a lead screw located inside the mounting cover. The surface of the lead screw is cooperatively connected with a ball nut, and one side of the outer circumference of the ball nut is provided with a scraping ring through a transmission rod. The scraping ring is sleeved on the outer circumference of the magnetic roller.

[0007] Further, it further includes a swing mechanism. A swing mechanism is provided between the hopper and the discharge pipe. The swing mechanism includes a motor B, a swivel ring, a rotating shaft A, a swing rod, a connecting rod, and a control rod. A motor B is installed on one side of the surface of the hopper, and a swivel ring is installed at the power end of the motor B. One side inside the hopper is movably connected to the swing rod through the rotating shaft A. The surface of the swing rod is connected to the surface of the swivel ring through the connecting rod. A control rod connected to the surface of the discharge pipe is installed at the end of the swing rod; when the motor B operates, it drives the swivel ring to continuously rotate. The swing rod can swing around the rotating shaft A. When the swivel ring rotates, the connecting rod on its surface continuously moves and drives the swing rod to move. During the continuous rotation of the swivel ring, the swing rod is driven to make a reciprocating motion, and then the discharge pipe is driven to continuously swing through the control rod, so as to evenly discharge the material onto the surfaces of the two magnetic rollers.

[0008] Further, a rubber ring is adhesively bonded to the inner circumference of the scraping ring and the rubber ring fits to the outer circumference of the magnetic roller. A discharge pipe is fixedly connected to the bottom of the silo at the position of the bottom of the magnetic roller. Impurity removal pipes are installed on both sides of the surface of the silo, and the ends of the impurity removal pipes extend to the ends of the magnetic rollers; the rubber ring structure ensures the scraping effect of the scraping ring on impurities and at the same time avoids damaging the magnetic roller. The screened powder is discharged through the discharge pipe, and the impurities are discharged from the inside of the impurity removal pipe.

[0009] Further, a blower is installed on one side of the surface of the hopper, and an exhaust duct extending to the top of the magnetic roller is installed at the air outlet end of the blower; the wind generated when the blower operates is blown onto the surface of the magnetic roller through the exhaust duct, and can purge the surface of the magnetic roller during the movement of the scraping ring, avoiding the residual powder being scraped into the impurity removal pipe.

[0010] Further, rotating shafts B are installed at both connection points of the connecting rod; the rotating shafts B play a connecting role, enabling the angles at both ends of the connecting rod to change within a certain range, and thus enabling the swivel ring to drive the swing of the swing rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects: There are two sets of magnet roller structures corresponding to each other inside the silo. The powder to be processed is put into the hopper. The discharge pipe continuously deflects to evenly discharge the powder onto the surfaces of the two magnet rollers on both sides. The magnet rollers are used to adsorb metal impurities in the powder. When the discharge pipe discharges the material towards one magnet roller, the motor A near the other magnet roller operates, driving the horizontal movement of the scraping ring through the screw drive assembly to scrape the impurities on the surface of the other magnet roller and make the impurities drain into the impurity removal pipe. When the angle of the discharge pipe changes, the scraping ring on the surface of the magnet roller in contact with the powder remains stationary, and the scraping ring on the surface of the magnet roller not in contact with the powder moves to clean the impurities. In this way, the impurities adsorbed by the magnet rollers can be quickly cleaned and discharged, avoiding the problem that the impurities stay on the surface of the magnet rollers for a long time and are washed away by the subsequently discharged powder, ensuring the impurity removal quality. When the motor B operates, it drives the rotating ring to continuously rotate. The swing rod can swing around the rotating shaft A. When the rotating ring rotates, the connecting rod on its surface continuously moves and drives the swing rod to move. During the continuous rotation of the rotating ring, the swing rod is driven to make a reciprocating motion, and then the discharge pipe is driven to continuously swing through the control rod, evenly discharging the material onto the surfaces of the two magnet rollers.

[0019] Furthermore, it also includes a swinging mechanism 3. A swinging mechanism 3 is arranged between the hopper 1 and the discharge pipe 204. The swinging mechanism 3 includes a motor B 301, a rotating ring 302, a rotating shaft A 303, a swinging rod 304, a connecting rod 305 and a control rod 307. The motor B 301 is installed on one side of the surface of the hopper 1 and the power end of the motor B 301 is installed with the rotating ring 302. One side inside the hopper 1 is movably connected with the swinging rod 304 through the rotating shaft A 303. The surface of the swinging rod 304 and the surface of the rotating ring 302 are connected through the connecting rod 305. The end of the swinging rod 304 is installed with the control rod 307 connected with the surface of the discharge pipe 204. When the motor B 301 operates, it drives the rotating ring 302 to rotate continuously. The swinging rod 304 can swing around the rotating shaft A 303. When the rotating ring 302 rotates, the connecting rod 305 on its surface moves continuously and drives the swinging rod 304 to move. During the continuous rotation of the rotating ring 302, it drives the swinging rod 304 to make a reciprocating motion, and further drives the discharge pipe 204 to swing continuously through the control rod 307, and discharges the materials evenly onto the surfaces of the two magnetic rollers 202.

A discharge pipe 212 is fixedly connected to the bottom of the material bin 201 at the position of the bottom of the magnetic roller 202. Impurity removal pipes 213 are respectively installed on both sides of the surface of the material bin 201, and the ends of the impurity removal pipes 213 extend to the ends of the magnetic roller 202. A blower 4 is installed on one side of the surface of the hopper 1, and an exhaust pipe 401 extending to the top of the magnetic roller 202 is installed at the air outlet end of the blower 4; the structure of the rubber ring 211 ensures the scraping effect of the scraping ring 210 on impurities, and at the same time avoids damaging the magnetic roller 202. The screened powder is discharged through the discharge pipe 212, and the impurities are discharged from the inside of the impurity removal pipe 213. The wind generated during the operation of the blower 4 is blown onto the surface of the magnetic roller 202 through the exhaust pipe 401, and the surface of the magnetic roller 202 can be purged during the movement of the scraping ring 210, avoiding the problem that the residual powder is scraped into the impurity removal pipe 213.

The powder to be processed is put into the hopper 1, and the discharge pipe 204 continuously deflects to evenly discharge the powder onto the surfaces of the two magnetic rollers 202 on both sides. The magnetic rollers 202 are used to adsorb metal impurities in the powder. When the discharge pipe 204 discharges the material towards one magnetic roller 202, the motor A206 near the other magnetic roller 202 operates, driving the horizontal movement of the scraping ring 210 through the lead screw 207 transmission assembly, scraping the impurities on the surface of the other magnetic roller 202 and discharging the impurities into the impurity removal pipe 213. When the angle of the discharge pipe 204 changes, the scraping ring 210 on the surface of the magnetic roller 202 in contact with the powder remains stationary, and the scraping ring 210 on the surface of the magnetic roller 202 not in contact with the powder moves to clean the impurities. In this way, the impurities adsorbed by the magnetic roller 202 can be quickly cleaned and discharged, avoiding the problem that the impurities stay on the surface of the magnetic roller 202 for a long time and are washed away by the subsequent discharged powder, ensuring the impurity removal quality; when the motor B301 operates, it drives the rotating ring 302 to continuously rotate, and the swing rod 304 can swing around the rotating shaft A303. When the rotating ring 302 rotates, the connecting rod 305 on its surface continuously moves and drives the swing rod 304 to move.
