Abstract
Description
Technical Field
[0001] This utility model relates to the field of permanent magnet separator technology, specifically a corrosion-resistant permanent magnet separator. Background Technology
[0002] A permanent magnet separator is a device used to remove iron from bulk non-magnetic materials. It is mainly used in industries such as building materials, chemicals, pharmaceuticals, and food. Its working principle is to use the strong magnetic field generated by permanent magnets to attract ferromagnetic substances from the material, thereby achieving the purpose of iron removal.
[0003] A Chinese patent provides a lifting permanent magnet separator, publication number CN221413467U, which includes a permanent magnet separator and a support frame. A lifting mechanism is installed at the end of the support frame, and the lifting mechanism is used to drive the permanent magnet separator to adjust its height.
[0004] The aforementioned permanent magnet separator is equipped with a lifting mechanism, which causes the rotating threaded rod to drive the slide to move up and down. The slide moves along the track of the slide rail, thereby enabling the permanent magnet separator to move up and down. This allows the permanent magnet separator to be adjusted to different heights according to the actual situation.
[0005] However, when removing iron from humus, the humus is relatively moist and contains corrosive liquids, which easily adhere to the iron separator belt. After long-term use, the belt will gradually be corroded, affecting its service life. Furthermore, if the humus or corrosive liquids are not cleaned in time, they may affect the iron removal performance. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] Combination Figures 1-3 A corrosion-resistant permanent magnet separator includes a permanent magnet separator body 2 movably mounted on a bracket 1. An electric telescopic rod 3 is installed on one side of the top of the permanent magnet separator body 2, and an installation ring 4 is fixedly installed at the end of the push rod of the electric telescopic rod 3.
[0026] See Figure 3 Furthermore, an installation plate 11 is provided between the permanent magnet separator body 2 and the cleaning pipe 5. The installation plate 11 is fixedly connected to the top of the permanent magnet separator body 2 near both sides via a support rod 10. An installation rod 12 is slidably installed through the upper and lower ends of the installation plate 11 near both sides. A brush head 13 is installed at one end of the installation rod 12 near the permanent magnet separator body 2 via a connecting plate. An anti-detachment spring 14 is provided between the upper and lower opposing surfaces of the connecting plate and the installation plate 11. Under the elastic force of the anti-detachment spring 14, the bottom end of the brush head 13 is in contact with the unloading belt of the permanent magnet separator body 2. An external thread is provided on the upper part of the outer ring of the installation rod 12, and an installation nut is connected to the installation rod 12 via the external thread. The brush head 13 is detachably connected to the installation plate 11 via the installation rod 12 and the installation nut.
[0027] Specifically, when the permanent magnet separator body 2 removes iron from the humus, the brush head 13 adheres to the unloading belt on the permanent magnet separator body 2, thus brushing off the adhering corrosive impurities and preventing them from mixing with corrosive liquids and adhering to the unloading belt on the permanent magnet separator body 2. At the same time, the brush head 13 is kept in close contact with the unloading belt of the permanent magnet separator body 2 by the elastic force of the anti-detachment spring 14 to improve the cleaning effect. The brush head 13 is fixed to the mounting plate 11 by the mounting rod 12 and mounting bolts, and can be disassembled and replaced when the brush head 13 is excessively worn or damaged.
[0028] Example 2
[0029] See Figure 2 Furthermore, based on Embodiment 1, a cleaning pipe 5 is rotatably installed on both sides of the mounting ring 4. Several nozzles 6 are arranged at the lower position of the outer ring of the cleaning pipe 5. A locking knob 7 that is compatible with the cleaning pipe 5 is threaded to the top of the mounting ring 4. An infusion pipe 8 is connected to one side of the cleaning pipe 5, and an infusion solenoid valve 9 is arranged between the infusion pipe 8 and the cleaning pipe 5. The permanent magnet separator body 2 consists of a magnetic circuit system, a frame, a drive roller, an unloading belt, and a connecting frame. The metal parts of the permanent magnet separator body 2 are made of 316 stainless steel, and the outer walls of the metal parts of the permanent magnet separator body 2 are coated with epoxy anti-corrosion paint. Several nozzles 6 are arranged at equal intervals on the cleaning pipe 5, and the sides of the nozzles 6 do not exceed the two sides of the unloading belt. The cleaning pipe 5 is a rigid pipe and does not contact the mounting rod 12 and the mounting plate 11. The brush head 13 is made of polypropylene.
[0030] Specifically, during the cleaning process of the brush head 13, the infusion pipe 8 can be connected to the external cleaning fluid delivery pipe in advance. Then, the infusion solenoid valve 9 can be opened intermittently. When opened, the cleaning fluid can be delivered to the cleaning pipe 5 and sprayed from the nozzle 6 at the cleaning pipe 5 onto the unloading belt of the permanent magnet separator body 2. This can wash off the adhering corrosive liquid. By rinsing in conjunction with brush head 13, the cleaning effect can be further improved, and the corrosive liquid and debris can be prevented from adhering to the permanent magnet separator body 2 for a long time, thereby improving corrosion resistance.
[0031] In actual operation, the height adjustment method of the permanent magnet separator body 2 and the bearings used for the transmission motor and each transmission roller of the permanent magnet separator body 2 are not described in detail here. When the permanent magnet separator body 2 removes iron from the humus, the corrosive impurities adhering to it can be brushed off by the way the brush head 13 is attached to the iron unloading belt on the permanent magnet separator body 2, so as to avoid it mixing with corrosive liquid and adhering to the iron unloading belt of the permanent magnet separator body 2.
[0032] Meanwhile, the brush head 13 is continuously pressed against the unloading belt of the permanent magnet separator body 2 by the elastic force of the anti-detachment spring 14 to improve the cleaning effect. The brush head 13 is fixed to the mounting plate 11 by the mounting rod 12 and the mounting bolt. When the brush head 13 is excessively worn or damaged, it can be disassembled and replaced.
[0033] During the cleaning process of the brush head 13, the infusion tube 8 can be connected to the external cleaning fluid delivery tube in advance. Then, the infusion solenoid valve 9 can be opened intermittently. When opened, the cleaning fluid can be delivered to the cleaning tube 5 and sprayed from the nozzle 6 at the cleaning tube 5 onto the unloading belt of the permanent magnet separator body 2, which can wash off the adhering corrosive liquid.
[0034] By rinsing and brushing with brush head 13, the cleaning effect can be further improved, and corrosive liquids and debris can be prevented from adhering to the permanent magnet separator body 2 for a long time, thereby improving corrosion resistance. The permanent magnet separator body 2 is made of stainless steel, and each component on the permanent magnet separator body 2 is coated with epoxy anti-corrosion paint, which can improve the corrosion resistance of the permanent magnet separator body 2 itself.
[0035] Furthermore, the control components and modules used in the aforementioned support rod 10 and permanent magnet separator body 2 are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve improvements to the software and power supply.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
