Description

Technical Field

[0001] The utility model relates to the technical field of powder material conveying, in particular to a powder material conveying and iron removal device which is easy to clean. Background Art

[0002] Although most of the main equipment for the production of well salt is made of anti-corrosion materials such as stainless steel, the long-distance brine pipelines are made of cast iron, which leads to the presence of fine black ferromagnetic impurities in the brine. In the processing of raw salt such as sea salt and lake salt, it is necessary to go through crushing, washing and other processes to remove impurities in the raw salt, improve the purity, and ensure that the raw salt particles are uniform. The finished salt produced by the powder washing salt workshop has many visible impurities, most of which are rust slag. The national standard clearly states that there must be no obvious foreign matter unrelated to salt, so it is necessary to remove the rust impurities in the raw salt to ensure that the product meets the requirements of the national standard. In the transportation of other powder materials similar to well salt, there are also rust impurities, which also need to be removed to ensure the quality of the product.

[0003] In the existing powder conveying, usually a magnetic bar is placed above the powder conveying belt to absorb the rust in the powder. The magnetic bar is fixed above the conveying belt through a bracket to absorb the rust in the conveyed powder. When there is a lot of rust on the magnet and it needs to be cleaned, it is necessary to use a tool to loosen the bracket fixing wire and lift the bracket for cleaning, or remove the magnetic bar from the bracket to prevent rust from falling onto the conveying belt during the cleaning process and contaminating the powder. The disassembly and assembly is cumbersome and takes a long time. Utility Model Content

[0004] The purpose of the utility model is to provide a powder conveying and iron removal device which is easy to clean, and can quickly move the magnetic rod outside the conveying belt to avoid pollution caused by rust falling during the cleaning process, without the need for disassembly and assembly, thereby improving the cleaning efficiency and eliminating safety hazards during cleaning.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a powder conveying and iron removal device that is easy to clean, including a bracket, a cross bar across the conveying belt is provided on the bracket, a magnetic rod connecting frame is rotatably connected to the cross bar, a plurality of magnetic rods whose length direction is consistent with the transportation direction of the raw salt are arranged on the magnetic rod connecting frame at intervals, an adjustment frame is provided on one side of the bracket, a limit rod capable of adjusting the front and rear positions is provided on the adjustment frame, the limit rod abuts against one side of the magnetic rod connecting frame and limits the rotation angle of the magnetic rod connecting frame, the length of the cross bar is greater than the width of the conveying belt, and the magnetic rod connecting frame can be moved to one side of the conveying belt.

[0006] A further improvement of the utility model is that the magnetic rod connecting frame includes a connecting tube rotatably connected to the cross bar, a straight plate is provided at the lower end of the connecting tube, and the magnetic rod is arranged on the plate surface of the straight plate.

[0007] A further improvement of the utility model is that the adjustment frame includes two vertical rods, a second cross rod is provided on the side opposite to the upper ends of the two vertical rods, a connecting plate is provided at the lower end of the second cross rod, a through hole is provided on the connecting plate, a screw is provided in the through hole, the screw is fixed to the connecting plate by a nut, and one end of the two screws is fixedly connected to the two ends of the limit rod respectively.

[0008] A further improved solution of the utility model is that the straight plate comprises a rectangular portion and an arc portion arranged at the lower end of the rectangular portion, and the plurality of magnetic bars are arranged on the straight plate in an arc shape.

[0009] A further improvement of the utility model is that the adjustment frame includes a base tube, a locking bolt is threadedly connected to the tube wall of the base tube, and the vertical rod is slidably connected in the base tube and fixed by the locking bolt.

[0010] A further improvement of the present invention is that the limiting rod and the cross bar are arranged in parallel.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides a cross bar and a magnetic rod connecting frame rotating thereon, and when cleaning, the magnetic rod connecting frame can be turned over and moved along the cross bar to the outside of the conveyor belt to avoid pollution caused by rust falling during the cleaning process, without the need for disassembly and assembly, thereby improving the cleaning efficiency.

[0013] The utility model provides a limit rod on one side of the straight plate through the adjustment frame, utilizes the gravity of the magnetic rod connecting frame itself to realize the abutment of the limit rod against the back side of the straight plate, and limits the rotation of the magnetic rod connecting frame in one direction. When cleaning, the reverse rotation will not be restricted, and the magnetic rod connecting frame can be directly turned over to speed up the adjustment speed.

[0014] The screw rod of the utility model is fixed on the connecting plate by a nut, and the position of the limit rod can be adjusted by adjusting the position of the bolt, thereby adjusting the position of the rotation restriction, and the adjustment is flexible and has a wide adaptability.

[0015] The utility model provides an arc-shaped portion at the lower end of the straight plate, and the plurality of magnetic bars are arranged in an arc shape on the straight plate. The existing raw salt transportation is generally carried out through a conveying belt. The arrangement of the arc-shaped portion can adapt to the arc-shaped conveying surface of the conveying belt, and the arc-shaped arrangement of the magnetic bars can better contact with the raw salt, thereby improving the rust removal effect.

[0016] During cleaning, the utility model quickly flips the magnetic rod connecting frame and moves it along the cross bar to the outside of the conveyor belt, and performs cleaning on the side outside the belt. Compared with the existing cleaning above the belt or complicated disassembly and assembly, the possibility of interference to personnel working above the belt due to inadvertent starting of the belt is reduced, safety hazards are reduced, and the safety of cleaning is improved.
