Description

Technical Field

[0001] This utility model relates to a self-cleaning iron remover, belonging to the field of industrial material impurity removal technology. Background Technology

[0002] Magnetic separators are widely used magnetic separation devices in industrial production. They are mainly used to remove impurities (such as iron nails, iron wires, and iron blocks) that can be removed by magnetic force from powdery and granular materials, thus protecting downstream equipment (such as crushers) from damage and improving product purity and quality. Currently, the main magnetic separation methods are permanent magnet sieving and electromagnet sieving. These two methods are widely used, but most traditional magnetic separators, especially permanent magnet separators, are not designed to achieve continuous and self-cleaning functions. That is, after adsorbing magnetic impurities, the impurities themselves adhere to the adsorption structure, making them difficult to remove, leading to impurity accumulation, affecting further impurity removal efficiency, and hindering cleaning. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a self-cleaning iron remover for removing magnetic impurities contained in tea powder during the preparation process of black tea powder. It can automatically discharge the adsorbed impurities during the removal process, achieving self-cleaning, eliminating the need for frequent manual maintenance and ensuring good removal efficiency.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides a self-cleaning iron remover, including a material cylinder and a driving device. An opening is provided in the middle of the material cylinder, and a rotating sleeve is provided on one side of the material cylinder. A rotating column is rotatably mounted inside the rotating sleeve. Multiple electromagnet columns are arranged in a circumferential array on the rotating column, and the multiple electromagnet columns can pass through the opening in the material cylinder. The driving device drives the rotating column to rotate. Multiple sets of terminals are provided on the rotating column, each set of terminals corresponding to one electromagnet column. Each set of terminals includes a positive contact and a negative contact. A positioning plate is installed above the material cylinder, and a positive arc-shaped conductive plate and a negative arc-shaped conductive plate are mounted on the positioning plate. The multiple positive and negative contacts can intermittently contact the positive and negative arc-shaped conductive plates through rotation, and the positive and negative arc-shaped conductive plates can supply power and generate magnetism to the corresponding electromagnet columns through the positive and negative contacts.

[0006] Specifically, a collection box is installed on one side of the material cylinder, and the collection box is located within the area where the electromagnet column is de-energized.

[0007] Specifically, each of the electromagnet columns is equipped with an arc-shaped magnetic guide edge, which is used to fill the blank area between two adjacent electromagnet columns and to generate electromagnetic force when the corresponding electromagnet column is energized.

[0008] Specifically, multiple arc-shaped magnetic guide edges are provided along the extension direction of the electromagnet column.

[0009] Specifically, the central angle range of the fan-shaped region formed by the positive arc-shaped conductive sheet and the negative arc-shaped conductive sheet coincides, and the central angle is not less than 180° and not greater than 270°.

[0010] Specifically, each of the positive and negative contacts is provided with an elastic pad at its bottom. The positive and negative contacts are electrically connected to the corresponding electromagnet post through an extendable wire. The positive and negative contacts are made of copper sheets.

[0011] Specifically, it also includes an arc-shaped mounting plate, which is fixedly connected to a positioning plate. The arc-shaped mounting plate has multiple arc grooves, all of which coincide with the center of the positive arc-shaped conductive sheet and the negative arc-shaped conductive sheet. The material cylinder has multiple positioning holes, and positioning bolts for positioning the arc-shaped mounting plate are inserted into the arc grooves.

[0012] Specifically, a hopper with a constricted opening is provided inside the material cylinder and above the opening, and a discharge port is installed below the material cylinder.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0014] This invention features a rotating column on one side of the material-passing cylinder, with an electromagnet column on the rotating column. The electromagnet column is intermittently conductive during rotation, generating a magnetic force to attract impurities as it passes through the inside of the cylinder. It automatically de-energizes after exiting the cylinder, thus losing its attraction to impurities and carrying them outside for removal. This design provides excellent self-cleaning capabilities, requires minimal manual maintenance, and ensures consistent impurity adsorption efficiency during extended operation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] This utility model provides a self-cleaning iron remover for removing magnetic impurities from tea powder during the preparation process of black tea powder. It automatically discharges adsorbed impurities during the removal process, achieving self-cleaning without frequent manual maintenance and ensuring good removal efficiency. To realize the structural function of the device, it includes a material cylinder 1 and a driving device 5. The material cylinder 1 is used for the material to be screened to pass through its interior. Specifically, an opening is provided in the middle of the material cylinder 1. Figure 1 As shown, a rotating sleeve 2 is provided on one side of the material cylinder 1. A rotating column 3 is rotatably arranged inside the rotating sleeve 2, and multiple electromagnet columns 4 are arranged in a circumferential array on the rotating column 3. Each electromagnet column 4 contains multiple electromagnetic coil units, which generate magnetic force to attract magnetic impurities when energized. Simultaneously, the multiple electromagnet columns 4 can pass through the opening in the material cylinder 1 from inside the cylinder. A driving device 5 is used to drive the rotating column 3 to rotate. Figure 5 As shown, a motor combined with belt drive can be used to drive the rotating column 3 to rotate. To achieve intermittent magnetization, the electromagnet column 4 can generate magnetic force to attract magnetic impurities when inside the material cylinder 1, and automatically demagnetize after moving outside the material cylinder 1, thus discharging the impurities. Multiple sets of terminals are provided on the rotating column 3, each set corresponding to one electromagnet column 4. Each set of terminals includes a positive contact 15 and a negative contact 16 for connecting the power supply. Figure 3 As shown, in order to intermittently energize the positive contact 15 and the negative contact 16, a positioning plate 6 can be installed above the material cylinder 1, as shown in the diagram. Figure 6 As shown, a positive arc-shaped conductive sheet 8 and a negative arc-shaped conductive sheet 7 are installed on the positioning plate 6. The dimensions are adjusted so that multiple positive contacts 15 and negative contacts 16 can intermittently contact the positive arc-shaped conductive sheet 8 and the negative arc-shaped conductive sheet 7 through rotation. It should be noted that the positive arc-shaped conductive sheet 8 and the negative arc-shaped conductive sheet 7 need to be continuously powered so that the positive contacts 15 and the negative contacts 16 can connect the electromagnet column 4 to supply power to the electromagnet column 4. That is, the positive arc-shaped conductive sheet 8 and the negative arc-shaped conductive sheet 7 can intermittently supply power to the corresponding electromagnet column 4 during the rotation of the positive contacts 15 and the negative contacts 16, thereby generating magnetic force to attract impurities in the powder or granular material. It should be noted that the energization range of the corresponding electromagnet column 4 must at least ensure that the electromagnet column 4 can be moved out of the material cylinder 1 when energized.

[0026] This utility model provides a self-cleaning iron remover. In order to facilitate the collection of impurities that fall off the demagnetized electromagnet column 4, a collection box 14 can be installed on one side of the material cylinder 1. The collection box 14 is located within the area where the electromagnet column 4 is de-energized, thereby facilitating the collection of magnetic impurities and ensuring a good working environment around the equipment.

[0027] This utility model provides a self-cleaning iron remover. Considering that with the above-mentioned method, if the moving speed of the electromagnet column 4 is slow, the gap between the electromagnet columns 4 may be too large, making it difficult for some magnetic impurities to be attracted. Conversely, if the moving speed of the electromagnet column 4 is too fast, it may cause the original material to be swept away, resulting in waste. Therefore, it is preferable to install an arc-shaped magnetic guide edge 11 on each electromagnet column 4. Figure 1 As shown, these arc-shaped magnetically conductive edges 11 are used to fill the blank area between two adjacent electromagnet columns 4. Corresponding electromagnetic coils can also be installed inside these coils to simultaneously power on the corresponding electromagnet column 4, so that the arc-shaped magnetically conductive edges 11 generate electromagnetic force when the corresponding electromagnet column 4 is energized. To ensure that the arc-shaped magnetically conductive edges 11 can cover a large area of ​​the material passing through inside the cylinder 1, multiple arc-shaped magnetically conductive edges 11 are provided along the extension direction of the electromagnet column 4.

[0028] This utility model provides a self-cleaning iron remover with a preferred conductive area. Preferably, there are 6 electromagnet columns 4. The central angles of the fan-shaped areas formed by the positive arc-shaped conductive sheet 8 and the negative arc-shaped conductive sheet 7 overlap, and the central angle is not less than 180° and not more than 270°. If the arc-shaped magnetic conductive edges 11 are evenly arranged, the corresponding leakage magnetic angle is at least 60 degrees, so as to ensure that the discharged impurities can be collected normally.

[0029] This utility model provides a self-cleaning iron remover. To ensure good contact between the contacts and the conductive sheet, each positive contact 15 and negative contact 16 is provided with an elastic pad at its bottom. Specifically, the corresponding positive contact 15 and negative contact 16 are electrically connected to the corresponding electromagnet post 4 through an extendable wire to avoid the rigidity of the circuit copper wire causing the contacts to be unable to adapt to the arc-shaped conductive sheet for contact. Preferably, both the positive contact 15 and the negative contact 16 are made of copper sheet.

[0030] This utility model provides a self-cleaning iron separator. To facilitate adjustment of the magnetic leakage area, the device may also include an arc-shaped mounting plate 9, such as... Figure 6 As shown, the arc-shaped mounting plate 9 is fixedly connected to the positioning plate 6, and specifically, multiple arc-shaped grooves 10 are formed on the arc-shaped mounting plate 9, such as... Figure 6As shown, these multiple arc grooves 10 all coincide with the center of the positive arc conductive sheet 8 and the negative arc conductive sheet 7, so that the center position will not change when the position of the arc conductive sheet is rotated and adjusted. In order to facilitate the fixing of the arc mounting plate 9, multiple positioning holes can be provided on the material cylinder 1, and positioning bolts for positioning the arc mounting plate 9 can be inserted into the arc grooves 10. When the angle needs to be adjusted, the corresponding bolt structure can be loosened.

[0031] This utility model provides a self-cleaning iron separator to prevent materials from being easily carried away by the electromagnet column 4 during the falling process, such as... Figure 5 As shown, a hopper 12 with a constricted opening can be provided inside the material cylinder 1 and above the opening to concentrate the area where the material falls and reduce the possibility of the material being carried away. A discharge port 13 is installed below the material cylinder 1 to facilitate the material entering the next process.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
