[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an explosion-proof magnetic absorber, including an explosion-proof magnetic absorber body 1, a limiting mechanism 2, a limiting arm 201, a limiting bolt 202, a positioning arm 3, a clamping sleeve 4, a bracket 5, a working bolt 6, a motor 7, a square rod 8, a square sleeve 9, a plate brush 10, a sleeve 11, a clamping rod 12 and a spring 13. A limiting mechanism 2 is installed at the end of the upper surface of the explosion-proof magnetic absorber body 1, and a positioning arm 3 and a clamping sleeve 4 are respectively fixed at the upper and lower ends of the end face of the explosion-proof magnetic absorber body 1. And the end of the positioning arm 3 is movably connected to a bracket 5, and a working bolt 6 is movably installed on the inner wall of the end of the bracket 5 close to the positioning arm 3. At the same time, a motor 7 is fixedly arranged on the end face of the bracket 5. The end of the output shaft of the motor 7 is fixedly connected to a square rod 8, and a square sleeve 9 is sleeved on the outer wall of the square rod 8. And a plate brush 10 is fixedly installed on the end face of the square sleeve 9. And a sleeve 11 is fixedly connected to the outer wall of the side of the square sleeve 9. At the same time, a clamping rod 12 is movably connected to the inner wall of the sleeve 11.

[0023] The limiting mechanism 2 includes a limiting arm 201 and a limiting bolt 202. The limiting arm 201 is fixedly installed on the upper surface of the explosion-proof magnetic absorber body 1, and a limiting bolt 202 is movably connected to the inner wall of the upper end of the limiting arm 201, which is convenient for limiting the plate brush 10 when it is not working through the limiting mechanism 2, so as not to affect the normal use of the explosion-proof magnetic absorber body 1.

[0024] The limiting bolt 202 is threadedly connected to the limiting arm 201 and the bracket 5 respectively, and the bracket 5 and the positioning arm 3 form a rotating structure, which is convenient for the user to rotate the limiting bolt 202, so that the limiting bolt 202 moves relative to the limiting arm 201 and disengages from the bracket 5, thereby facilitating the user to push the bracket 5 to rotate around the positioning arm 3, so that the bracket 5 drives the plate brush 10 to fit the explosion-proof magnetic absorber body 1 for cleaning the explosion-proof magnetic absorber body 1.

[0025] The clamping sleeve 4 and the bracket 5 are in contact with each other, and the clamping sleeve 4 and the bracket 5 are respectively threadedly arranged with the working bolt 6, which is convenient for the plate brush 10 to just fit the explosion-proof magnetic absorber body 1 when the bracket 5 rotates and fits the clamping sleeve 4, and is convenient for the user to rotate the working bolt 6, so that the working bolt 6 moves relative to the bracket 5 and inserts into the clamping sleeve 4, thereby limiting the plate brush 10 and making the plate brush 10 stably fit the explosion-proof magnetic absorber body 1.

[0026] The square rod 8 and the square sleeve 9 form a sliding structure. The brush 10 and the explosion-proof magnetic absorber body 1 are fitted and connected. When the user disassembles and installs the brush 10, the brush 10 drives the square sleeve 9 to slide relative to the square rod 8, and it is convenient for the brush 10 to fit the explosion-proof magnetic absorber body 1, so as to clean the explosion-proof magnetic absorber body 1.

[0027] The clamping rod 12 is respectively slidably connected with the square rod 8, the square sleeve 9 and the sleeve 11, and the inner wall of the end of the sleeve 11 is connected to the surface of the clamping rod 12 through a spring 13. It is convenient for the user to pull the clamping rod 12, so that the clamping rod 12 moves relative to the square sleeve 9 and the sleeve 11 and disengages from the square rod 8, thus facilitating the user to disassemble and assemble the brush 10, and the spring 13 elastically supports the clamping rod 12, so that the clamping rod 12 is stably inserted into the square rod 8.

[0028] Working principle: When using this explosion-proof magnetic absorber, first as Figure 1 , Figure 3 and Figure 5 shown, the user pulls the clamping rod 12. At this time, the clamping rod 12 moves relative to the square sleeve 9 and the sleeve 11 and compresses the spring 13 to deform. Then the user moves the brush 10 so that the brush 10 drives the square sleeve 9 to be sleeved outside the square rod 8. Next, the user releases the clamping rod 12. At this time, the spring 13 resets and pushes the clamping rod 12 to insert into the square rod 8, thus completing the installation of the brush 10. Then as Figures 1 - 2 and Figures 4 - 5 shown, the user holds the explosion-proof magnetic absorber body 1 and starts the explosion-proof magnetic absorber body 1 to move on the waste. At this time, the explosion-proof magnetic absorber body 1 adsorbs the magnetic substances in the waste, thus completing the separation of the magnetic substances. When the surface of the explosion-proof magnetic absorber body 1 is contaminated with dust and needs to be cleaned, the user turns off the explosion-proof magnetic absorber body 1 and rotates the limit bolt 202. Then the limit bolt 202 moves relative to the limit arm 201 and disengages from the bracket 5. Next, the user pushes the bracket 5 to rotate around the positioning arm 3. Subsequently, as the bracket 5 continues to rotate, finally the bracket 5 fits the bushing 4, and at the same time the bracket 5 drives the brush 10 to fit the explosion-proof magnetic absorber body 1. Then the user rotates the working bolt 6. Next, the working bolt 6 moves relative to the bracket 5 and inserts into the bushing 4, thus completing the limit of the brush 10, making the brush 10 stably fit the explosion-proof magnetic absorber body 1. Then the user starts the motor 7. Then the motor 7 drives the square rod 8, so that the brush 10 rotates relative to the explosion-proof magnetic absorber body 1. At this time, the brush 10 cleans the dust on the surface of the explosion-proof magnetic absorber body 1. Therefore, the device is convenient for cleaning the surface dust, thus avoiding dust interfering with the use of the device and improving the practicability of the device.

[0029] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
