Description

Technical Field

[0001] This utility model belongs to the field of polyethylene wax powder production technology, specifically relating to a polyethylene wax powder equipment with adjustable powder particle size. Background Technology

[0002] Polyethylene wax is widely used due to its excellent cold resistance, heat resistance, chemical resistance, and abrasion resistance. In normal production, this wax can be directly added to polyolefin processing as an additive to increase the gloss and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, and polyvinyl acetate, and can improve the flowability of polyethylene and polypropylene, as well as the mold release properties of polymethyl methacrylate and polycarbonate. Compared with PVC and other external lubricants, polyethylene wax has a stronger internal lubricating effect. To adapt to industrial production, oxidized polyethylene wax sometimes needs to be pulverized into powder for use.

[0003] A search revealed a Chinese patent (authorization announcement number CN217144509U) disclosing a production apparatus for polyethylene wax powder. This patented technology features a refining tank with a primary separation plate and a secondary separation plate sequentially fixed to its inner wall. The tank contains a refining structure, including a vertical shaft positioned within it. A drive bevel gear is welded to the top of the shaft, and a first refining roller and a second refining roller are sequentially fixed to the shaft. Multiple first and second refining rollers are equidistantly arranged. This invention enables multiple refining stages of the polyethylene wax powder produced by the pulverizer, resulting in a higher degree of refinement and smaller particle size, thus improving product quality. The refining structure provides excellent refining effect and allows for multi-stage refining.

[0004] However, in practical applications, this patented technology cannot produce polyethylene wax powder of the corresponding particle size according to usage requirements. Consequently, in actual production, polyethylene wax powder can only be produced to a certain specification based on the physical characteristics of the refining roller of the equipment. This results in certain limitations in the production of polyethylene wax powder, making it necessary to propose a device that can adjust the particle size of polyethylene wax powder.

Detailed Implementation

[0026] 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.

[0027] This specific embodiment is a polyethylene wax powder equipment with adjustable powder particle size, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the device includes a grinding box 1 and a grinding seat 15 fixed at the center of the inner wall of the grinding box 1. An installation component 11 is embedded in the grinding box 1 and located above the grinding seat 15. The bottom end of the installation component 11 is slidably connected to a grinding block 14 corresponding to the grinding seat 15 via fasteners. A drive mechanism for rotating the installation component 11 is provided above the grinding box 1. A perforated guide plate 6 is fixed at the bottom end of the inner wall of the grinding box 1. A water storage cavity 8 is provided between the guide plate 6 and the grinding box 1.

[0028] Preferably, the fastener is a knob bolt 17 that is rotatably inserted into both sides of the top surface of the mounting part 11. The outer wall of the knob bolt 17 is fixed with a protrusion 18 that engages with the mounting part 11. The bottom end of the knob bolt 17 is threaded into the crushing block 14. The crushing block 14 and the crushing seat 15 are both fixed with crushing teeth 16 in a ring array at their respective ends, and the crushing teeth 16 on the crushing block 14 and the crushing seat 15 are staggered. The top of the inner wall of the crushing box 1 is fixed with a support rod 12 in a ring array, and the outer wall of the crushing box 1 is fixed with multiple support legs 5 in a ring array, driving... The mechanism includes a motor 2 fixed to the top of the support rod 12 and a drive shaft 13 rotatably connected to the bottom of the support rod 12 and the motor 2. The bottom of the drive shaft 13 is fixedly connected to the mounting part 11. The crushing teeth 16 between the crushing block 14 and the crushing seat 15 crush the polyethylene wax. The knob bolt 17 is threaded into the crushing block 14. When the knob bolt 17 is tightened, it drives the crushing block 14 to rise and fall in the mounting part 11, so that the crushing block 14 adjusts the distance between itself and the crushing seat 15 during the rising and falling process, thereby adjusting the particle size of the polyethylene wax powder.

[0029] like Figure 3 and Figure 4As shown, a discharge pipe 4 is installed at the center of the bottom end face of the crushing box 1, and a return pipe 3 and a conveying pipe 9 are fixedly installed on both sides of the outer wall of the crushing box 1, respectively. A cooling chamber 10 is opened in the crushing base 15. The two ends of the conveying pipe 9 are connected to the cooling chamber 10 and the water storage chamber 8, respectively, and the bottom end of the conveying pipe 9 extends into the water storage chamber 8 and is equipped with a water pump 7. The top end of the return pipe 3 extends into the crushing box 1 and is fixed to the bottom end of the crushing base 15, and the two ends of the return pipe 3 are connected to the bottom of the cooling chamber 10 and the water storage chamber 8, respectively. Due to polyethylene The heat generated during the wax crushing process is limited. The circulating cooling water can dissipate heat naturally in the water storage chamber 8, thus keeping the circulating cooling water at a low temperature for a long time. The temperature rise caused by the cooling water absorbing heat is negligible. Both the crushing seat 15 and the crushing block 14 are made of metal, which can effectively achieve heat conduction. During the crushing process, the water pump 7 inputs the cooling water in the water storage chamber 8 into the cooling chamber 10 through the delivery pipe 9, and cools the inner wall of the crushing seat 15, reducing the thermal adhesion caused by the friction and heating of polyethylene wax.

[0030] Working principle: When using the device of this technical solution, polyethylene wax raw material is put into the top of the crushing box 1, and the motor 2 is started to drive the drive shaft 13 to drive the mounting part 11 and the crushing block 14 to rotate synchronously. The crushing teeth 16 on the crushing block 14 and the crushing seat 15 crush the polyethylene wax raw material. When adjusting the particle size of the polyethylene wax, the knob bolt 17 is threaded into the crushing block 14. During the tightening process of the knob bolt 17, the crushing block 14 is driven to rise and fall in the mounting part 11, so that the distance between the crushing block 14 and the crushing seat 15 is adjusted during the rising and falling process. The particle size of the polyethylene wax powder is adjusted by adjusting the crushing distance. During the crushing process, the water pump 7 inputs the cooling water in the water storage chamber 8 into the cooling chamber 10 through the delivery pipe 9, and cools the inner wall of the crushing seat 15, reducing the thermal adhesion caused by friction heating of polyethylene wax.

[0031] All technical features in this embodiment can be freely combined according to actual needs.
