Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polyethylene powder production, in particular to a high-density polyethylene powder processing tank. Background Technique
[0002] Polyethylene is a thermoplastic resin obtained by polymerizing ethylene. Polyethylene is odorless, non-toxic, and feels like wax. It has excellent low-temperature resistance (the lowest service temperature can reach -100 to -70 °C), good chemical stability, and can resist the erosion of most acids and alkalis (except acids with oxidizing properties). Polyethylene resin is a non-toxic, odorless white powder or granule, with a milky white appearance, a waxy feel, and a low water absorption rate, less than 0.01%.
[0003] Polyethylene has many advantages, and the biggest advantage is its strong corrosion resistance, which is determined by the stability of the polyethylene molecular structure because its molecular structure is very stable. Therefore, common chemical corrosion in life, such as natural gas and liquefied gas, will not have any impact on it. If polyethylene is buried in the soil, the chemical substances in the soil cannot degrade polyethylene. Therefore, under the premise of only considering corrosion, polyethylene pipes have an extremely long service life.

The existing processing tanks for polyethylene powder lack an effective mechanism for filtering out iron impurities.

[0025] By setting an iron removal mechanism consisting of a plastic shell 6, a permanent magnetic plate 12 and a guide rod 17 between the crushing mechanism and the feeding mechanism, and setting the entire iron removal mechanism obliquely downward, the iron powder in the polyethylene powder is adsorbed and removed, thereby ensuring the processing efficiency of the polyethylene powder and also ensuring the quality of the polyethylene powder.
[0026] Reference Figure 1 and Figure 2 In order to achieve the purpose of automatically crushing and grinding the polyethylene powder, the crushing mechanism includes two grinding rollers 14 horizontally rotatably connected to the inner wall of the processing box 2, the bottom surfaces of the two grinding rollers 14 are jointly attached to a grinding plate 13, the grinding plate 13 is suspended and fixed in the processing box 2, and the top surface of the grinding plate 13 is vertically provided with a plurality of equally distributed leakage holes, the grinding plate 13 is located above the iron removal mechanism, the outer side of the processing box 2 is horizontally fixed with a crushing motor 3, the crushing motor 3 is transmission-connected to the end of one of the grinding rollers 14, the other side of the processing box 2 is fixedly connected to a machine cover 10, and two mutually meshing gears are rotatably connected in the machine cover 10, and a gear is concentrically fixed at the end of each grinding roller 14.
[0027] By setting up a crushing component composed of two grinding rollers 14 and a grinding plate 13 with leakage holes, it plays a role in automatically crushing and grinding polyethylene. There is no need to manually crush and grind, which not only improves the crushing efficiency and quality of polyethylene, but also reduces the workload of operators and liberates people's hands.
[0028] Refer to Figure 1 and Figure 2 In order to achieve the purpose of automatically feeding the polyethylene powder in the process, the feeding component includes multiple conveying rollers 11 horizontally and rotatably connected in the processing box 2. The conveying rollers 11 are located on one side of the discharge port 7. A conveyor belt 9 is commonly sleeved on the outer edges of the multiple conveying rollers 11.

[0030] Working principle: When in use, the polyethylene to be crushed is put into the processing box 2 through the hopper 1. The grinding roller 14 and the grinding plate 13 crush the polyethylene. The crushed polyethylene will pass through the leakage holes on the grinding plate 13 and fall into the plastic sleeve 6 below. The permanent magnet plate 12 in the plastic sleeve 6 uses magnetism to adsorb the iron in the polyethylene powder outside the plastic shell, so that the iron powder is adsorbed outside the plastic sleeve 6. The polyethylene powder after iron removal falls onto the conveyor belt 9 through the inclined plastic sleeve 6 and is sent to the feeding port by the conveyor belt 9. When it is necessary to clean the collected iron powder, only need to loosen and remove the bolt 15, then pull out the sleeve 6 together with the permanent magnet plate 12 from the through groove 4, so that the sleeve 6 and the permanent magnet plate 12 are separated from the guide rod 17, and then separate the sleeve 6 and the permanent magnet plate 12 from the powder. When the sleeve 6 and the permanent magnet plate 12 are separated, the magnetism on the sleeve 6 disappears, and the iron powder adsorbed outside the sleeve 6 will automatically fall off from the outside of the sleeve 6. After the cleaning is completed, put the permanent magnet plate 12 back into the sleeve 6, then dock the sleeve 6 and the permanent magnet plate 12 with the guide rod 17 through the first through hole 16 and the third through hole, and then plug them back into the processing box 2 through the through groove 4, and then fix them with the bolt 15.
