Description

Technical Field

[0001] The utility model relates to the technical field of magnetic block installation of a magnetic separator, in particular to a magnetic block installation device of a magnetic separator. Background Art

[0002] Magnetic separators are mainly used in the field of recycling magnetic materials in the mineral processing and coal processing industries. The magnetic block device inside the drum of the magnetic separator is a key component of the magnetic separator. After a long period of operation, the drum skin will wear out or even wear through, causing foreign matter or media to enter the drum, and the magnetism of the internal magnetic block will also weaken. This requires maintenance of the magnetic block device inside the drum.

[0003] In the past, when replacing or assembling the magnetic block device, a sling was used to tie it to the shaft of the magnetic block device (wherein the magnetic block device includes a magnetic block unit and a shaft body connected to the magnetic block unit, and the magnetic block unit and the shaft body are connected as a whole before being installed in the cylinder skin), and then a forklift was used to lift the magnetic block device. This not only takes up equipment, has low work efficiency, but also is difficult to install.

[0004] For example, a magnetic block installation device for a magnetic separator disclosed in Chinese patent CN216105572U is provided, which is connected and fixed by connecting a hook with a corresponding position of the shaft of the magnetic block module through a sling on the hook, and then connected to the hook with a crane or other lifting equipment to lift the hook. After the hook is lifted, the hook must ensure that the magnetic block module remains horizontal or in a nearly horizontal state after being lifted. After being lifted to a suitable height, the magnetic block module is passed through the inside of the drum skin as a whole and adjusted to a suitable position (or the magnetic block module is kept stationary, and the drum skin is inserted from one end and adjusted to a suitable position), the drum end cover is passed onto the shaft of the magnetic block module, and then the support is moved to a suitable position, and the two ends of the shaft are placed on the support seat to complete the installation of the magnetic block module.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0029] The adjustment structure includes a connecting shaft 101, with rotating blocks 102 installed at both ends of the connecting shaft 101, an extension block 103 connected to the outer surfaces of the connecting shaft 101 and the rotating block 102, a hydraulic cylinder 104 installed on the bottom surface of the extension block 103, an abutment plate 105 installed on the output end of the hydraulic cylinder 104, and an insertion rod 106 installed in the middle of the bottom surface of the abutment plate 105.

[0030] The lifting structure includes a base 201, a hydraulic cylinder 202 is installed in the middle of the top surface of the base 201 near the left and right ends, a lifting platform 203 is installed at the output end of the hydraulic cylinder 202, and a slider 204 is installed in the middle of the front and back and the middle of the left and right sides of the lifting platform 203. A guide rail 205 is slidably connected to the outer surface of the slider 204, and a protective plate 206 is connected to the side of the guide rail 205 away from the slider 204. The bottom surface of the base 201 is fixedly connected to the top of the support leg 1, the bottom end of the guide rail 205 is fixedly connected to the top surface of the base 201, and the bottom end of the protective plate 206 is fixedly connected to the top surface of the base 201. A rotating groove is opened in the middle of the left and right sides of the base 201 near the front end and the back end, and the inner wall of the rotating groove is rotatably connected to the connecting shaft 101 and the end of the rotating block 102 away from the extension block 103.

[0031] By setting the adjustment structure, utilizing the rotational connection between the connecting shaft 101 and the rotating block 102 and the extending block 103, when the hydraulic cylinder 104 is started to extend and retract, the horizontal state of the base 201 can be effectively adjusted, so as to facilitate the installation of the magnetic block and the shaft.

[0032] When installing the magnet and the shaft, after the magnet and the shaft are spliced ​​on the top of the splicing table, start the hydraulic cylinder 104 to extend uniformly, insert the insertion rod 106 into the bottom surface, and then independently control the hydraulic cylinder 104, and use the rotation connection between the extension block 103, the rotating block 102, the connecting shaft 101, and the base 201 to effectively adjust the horizontal state of the base 201, so that the magnet and the shaft and the tube skin are in a relatively horizontal state, and then start the hydraulic cylinder 202 to drive the lifting platform 203 to extend, so that the lifting platform 203 can be raised, which is more convenient for the subsequent installation of the magnet and the shaft.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, the mounting structure includes a mounting unit and a buffer unit, the mounting unit includes a splicing table 304, an electromagnetic coil 305 is installed inside the splicing table 304, a telescopic rod 306 is installed on the front and back ends of the left end of the splicing table 304, a mounting plate 307 is installed on the right end of the top surface of the splicing table 304, an electric push rod 308 is installed near the top of the middle part of the right side of the mounting plate 307, and a push plate 309 is installed at the output end of the electric push rod 308.

At the same time, the repulsive magnetic force generated by the electromagnetic coil 305 and the magnetic block is used to facilitate pushing the magnetic block and the shaft into the interior of the tube skin.

[0037] When assembling the magnetic block, the magnetic block is placed on the top surface of the splicing table 304, which will squeeze the slide column 302, causing the slide column 302 to slide inside the slide cylinder 301, and at the same time squeeze the spring 303, thereby buffering the force of placing the magnetic block. When installing the magnetic block, first use the telescopic rod 306 to measure the height and direction of the magnetic block installation to ensure the accuracy of the installation. By energizing the electromagnetic coil 305 to generate a magnetic force that repels the magnetic block, the electric push rod 308 is then started to drive the push plate 309 to move, thereby pushing the magnetic block to move toward the inside of the cylinder skin.
