A non-ferrous metal screening machine that facilitates the removal of non-magnetic metals.

Abstract

This utility model relates to the field of non-ferrous metal screening technology, and in particular to a non-ferrous metal screening machine that facilitates the removal of non-magnetic metals. It includes a water tank and a shell. A fixing plate is bolted between the surface of the water tank and the surface of the shell. A short rod is rotatably connected to the inner wall of the shell via a bearing. This utility model adds water to the water tank, and then the raw material is added to the water tank. The water removes charged ions carried by dust and impurities in the raw material, effectively preventing magnetic dust and impurities from adsorbing onto the surface of magnetic metals during screening and interfering with the screening operation of the permanent magnet roller. The rotation of the motor drives the rotation of the roller and conveyor belt, which in turn drives the rotation of the baffle, continuously lifting the raw material in the water tank.

Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal screening technology, specifically a non-ferrous metal screening machine that facilitates the removal of non-magnetic metals. Background Technology

[0002] Silicon contains some impurities, and screening is required during the processing of silicon. Common silicon screening machines can only remove magnetic metals mixed in with silicon. They cannot effectively remove non-magnetic metals such as stainless steel and aluminum. Non-magnetic metals, also known as paramagnetic substances, exhibit random thermal vibrations of atoms in the absence of an external magnetic field. They appear to have no magnetism from a macroscopic perspective. Although the content of non-magnetic metals is low, it can still affect the quality of the produced products. Therefore, a non-ferrous metal screening machine is needed to remove non-magnetic metals.

[0003] A search revealed that the announcement number is CN210585377U, titled "A Non-ferrous Metal Screening Machine for Convenient Removal of Non-magnetic Metals," which includes a machine body, a motor, and a cooling fan. Research and analysis revealed that although it has the advantage of separating non-magnetic metals from silicon materials, it also has the following disadvantages to some extent.

[0004] For example, the raw materials may contain a certain amount of magnetic dust and impurities that have temporarily acquired a small amount of magnetism due to prolonged contact with magnetic materials. In this case, the magnetic dust and impurities will be adsorbed on the surface of the magnetic metal. It is difficult to remove all the magnetic dust and impurities by relying solely on the suction force of the blower. The excess magnetic dust and impurities will be sorted together with the non-ferrous metals, which can easily interfere with the screening work of the permanent magnet roller. In order to solve the above technical problems, we have designed a non-ferrous metal screening machine that can easily remove non-magnetic metals. Utility Model Content

[0009] Preferably, the front end of the connecting rod is fixedly connected to the rear end of the right roller, and there are two pulleys, which are respectively fixedly connected to the rear end of the connecting rod and the rear end of the short rod on the rear side, and the belt drive is sleeved on the surface of the two pulleys.

[0010] Preferably, there are five guide rods, which slide through the left side of the housing respectively. The right end of each guide rod is fixedly connected to the left side of the scraper. There are five springs, which are movably sleeved on the surface of the guide rods respectively.

A square rod is slidably inserted through the top of both the front and back sides of the housing. The end of the square rod near the guide frame is fixedly connected to one side of the guide frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model involves adding water to a water tank, followed by the raw materials. The water removes charged ions from dust and impurities in the raw materials, effectively preventing magnetic dust and impurities from adsorbing onto the surface of magnetic metals during screening. This avoids excess magnetic dust and impurities from being separated with non-ferrous metals, thus preventing interference with the screening operation of the permanent magnet roller. The operation of the motor and hot air blower is controlled. The rotation of the motor drives the rotation of the rollers and conveyor belt, which in turn drives the rotation of the baffles, continuously lifting the raw materials in the water tank. The operation of the hot air blower sprays hot air from the nozzle through the connecting pipe, thus having the advantage of drying the lifted raw materials, improving the screening effect of non-ferrous metals, and avoiding the effect of excessive moisture in the raw materials during screening.

[0016] 2. This utility model uses the rotation of the roller to drive the rotation of the connecting rod and the belt pulley and guide column. The rotation of the guide column drives the vertical rod and connecting plate to move back and forth, which in turn drives the block and square rod to move back and forth, causing the guide frame to move back and forth. This has the advantage of being able to vibrate the raw materials that fall into the guide frame after being lifted and dried, so that the raw materials fall more smoothly onto the surface of the permanent magnet roller for screening. With the cooperation of the belt pulley and belt, the short rod and the permanent magnet roller rotate. The rotation of the permanent magnet roller magnetically attracts the non-ferrous metals that fall onto its surface, while the non-magnetic metals fall onto the slag discharge hopper and are discharged. As the permanent magnet roller rotates, the scraper scrapes off the non-ferrous metals on its surface and they fall into the discharge hopper for discharge. Attached Figure Description

Detailed Implementation

[0023] Please see Figures 1-5 A non-ferrous metal screening machine for easy removal of non-magnetic metals includes a water tank 1 and a shell 2. A fixing plate 3 is fixedly connected between the surface of the water tank 1 and the surface of the shell 2 by bolts. Short rods 4 are rotatably connected to the inner wall of the shell 2 by bearings. Permanent magnet rollers 5 are fixedly connected to one end of the two short rods 4. A conveying mechanism 6 is installed on the inner wall of the water tank 1. A drying mechanism 7 is installed on the top of the water tank 1. A guide frame 8 is installed on the top of the shell 2. A scraping mechanism 9 is installed on the inner wall of the shell 2.

[0024] The conveying mechanism 6 includes a roller 61, a conveyor belt 62, a baffle 63, a motor 64, a connecting rod 65, a pulley 66, and a belt 67. The scraping mechanism 9 includes a guide rod 91, a scraper 92, and a spring 93. The drying mechanism 7 includes a frame 71, a hot air blower 72, a connecting pipe 73, and a nozzle 74.

[0025] Please see Figure 1 and Figure 3 There are two rollers 61, which are embedded in the inner wall of the water tank 1 through bearings. The conveyor belt 62 is driven and sleeved on the surface of the two rollers 61. There are several baffles 63, which are fixedly connected to the surface of the conveyor belt 62. By setting the baffles 63, the raw materials in the water tank 1 are continuously lifted and conveyed upward under the action of the continuous rotation of the conveyor belt 62. One side of the motor 64 is fixedly connected to the right side of the front of the water tank 1 by bolts, and the rotating shaft of the motor 64 is fixedly connected to the front end of the rollers 61.

[0026] Please see Figure 2 , Figure 3 and Figure 5 The front end of the connecting rod 65 is fixedly connected to the rear end of the right roller 61. There are two belt discs 66, which are fixedly connected to the rear end of the connecting rod 65 and the rear end of the short rod 4 respectively. The belt 67 is driven and sleeved on the surface of the two belt discs 66. By setting the belt discs 66 and the belt 67, the roller 61 is rotated under the drive of a motor 64, which drives the conveyor belt 62 to rotate. At the same time, the short rod 4 is rotated, which drives the permanent magnet roller 5 to rotate.

[0027] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 There are five guide rods 91, which slide through the left side of the housing 2. The right end of the guide rod 91 is fixedly connected to the left side of the scraper 92. By setting the guide rods 91, the scraper 92 is guided and limited, and can also move. There are five springs 93, which are movably sleeved on the surface of the guide rods 91. The two ends of the springs 93 are in contact with the inner wall of the housing 2 and the surface of the scraper 92, respectively. By setting the springs 93, the scraper 92 is kept in contact with the surface of the permanent magnet roller 5 under the action of its elastic force, thereby improving the scraping effect.

[0028] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the frame 71 is fixedly connected to the top of the water tank 1 by bolts. The bottom of the hot air blower 72 is fixedly connected to the top of the frame 71 by a support. The upper end of the connecting pipe 73 passes through the frame 71 and is connected to the output end of the hot air blower 72. There are several nozzles 74, and all of them are connected to the surface of the connecting pipe 73.

[0029] Please see Figure 1 , Figure 2 and Figure 5 A vibration mechanism 10 is installed on the surface of the housing 2. The vibration mechanism 10 includes a guide post 101, which is fixedly sleeved on the surface of the rear end of the connecting rod 65. A square rod 102 is slidably provided through the top of both the front and back sides of the housing 2. The square rod 102 guides and limits the guide frame 8. The end of the square rod 102 near the guide frame 8 is fixedly connected to one side of the guide frame 8. A square block 103 is welded to the end of the square rod 102 away from the guide frame 8. A connecting plate 104 is welded to the left side of the rear square block 103. By setting the connecting plate 104, the vertical rod 105 is indirectly connected to the rear square block 103, so that the vertical rod 105... When moving, it can drive the block 103 to move. A vertical rod 105 is welded to the left side of the top of the connecting plate 104. The surface of the guide post 101 is provided with a guide groove that matches the vertical rod 105. The upper end of the vertical rod 105 extends into the inner cavity of the guide groove. By setting the guide post 101 and the guide groove, its rotation can drive the vertical rod 105 to move back and forth, thereby driving the connecting plate 104 and the block 103 to move back and forth. A second spring 106 is movably sleeved on the front end of the square rod 102. By setting the second spring 106, the block 103 and the square rod 102 are more stable when moving, thereby making the guide frame 8 more stable when moving.

[0030] Please see Figure 1 and Figure 3A slag discharge hopper 11 is fixedly connected to the right side of the bottom of the shell 2, and a material discharge hopper 12 is fixedly connected to the left side of the bottom of the shell 2.

[0031] In use, water is added to water tank 1, followed by the raw material. The water removes charged ions from dust and impurities in the raw material, effectively preventing magnetic dust and impurities from adhering to the surface of the magnetic metal during screening. This prevents excess magnetic dust and impurities from being separated with non-ferrous metals, thus avoiding interference with the screening operation of the permanent magnet roller 5. The operation of motor 64 and hot air blower 72 is controlled. The rotation of motor 64 drives the rotation of roller 61 and conveyor belt 62, which in turn drives the rotation of baffle 63, continuously lifting the raw material in water tank 1. The operation of hot air blower 72 sprays hot air from nozzle 74 through connecting pipe 73, which dries the lifted raw material, preventing it from being too wet during screening and affecting the effect. The rotation of the roller 61 drives the connecting rod 65 and the belt pulley 66 on it to rotate with the guide column 101. The rotation of the guide column 101 drives the vertical rod 105 and the connecting plate 104 to move back and forth, which in turn drives the block 103 and the square rod 102 to move back and forth, causing the guide frame 8 to move back and forth. This can vibrate the raw materials that fall into the guide frame 8 after being lifted and dried, so that the raw materials fall more smoothly onto the surface of the permanent magnet roller 5 for screening. With the cooperation of the belt pulley 66 and the belt 67, the short rod 4 and the permanent magnet roller 5 rotate. The rotation of the permanent magnet roller 5 magnetically attracts the non-ferrous metals that fall onto its surface, while the non-magnetic metals fall onto the slag discharge hopper 11 and are discharged. As the permanent magnet roller 5 rotates, the scraper 92 scrapes off the non-ferrous metals on its surface and they fall into the discharge hopper 12 for discharge.

[0032] In summary, this non-ferrous metal screening machine, which facilitates the removal of non-magnetic metals, utilizes a combination of a water tank 1, a housing 2, a fixed plate 3, a short rod 4, a permanent magnet roller 5, a conveying mechanism 6, a drying mechanism 7, a guide frame 8, and a scraping mechanism 9. This solves the problem that raw materials may contain a certain amount of magnetic dust or impurities that have temporarily acquired a small amount of magnetism due to prolonged contact with magnetic materials. Relying solely on the suction force of the induced draft fan is insufficient to remove all magnetic dust and impurities, and performing simultaneous sorting can easily interfere with the permanent magnet roller screening process.
