Description

Technical Field

[0001] This utility model belongs to the field of polyethylene wax screening technology, specifically relating to a screening device for granulation inspection of ultra-high molecular weight polyethylene wax. Background Technology

[0002] Polyethylene wax, also known as high molecular weight wax, has excellent cold resistance, chemical resistance, and abrasion resistance. In recent years, with the progress and development of my country's industry, ultra-high molecular weight polyethylene wax granules have been widely used in various fields of chemical machinery due to their superior performance. In the production and preparation process of ultra-high molecular weight polyethylene wax granules, they need to be processed to make them into granules. During pelleting, stress can easily cause inconsistent pellet sizes. Therefore, subsequent screening of polyethylene wax granules is required, which necessitates the use of screening equipment.

[0003] Currently, screening devices often suffer from the following problems during operation due to their open, free-fall feeding system design and lack of management structure: First, because ultra-high molecular weight polyethylene wax is a material that easily agglomerates, multiple clumps may already exist before or during feeding. When these clumps fall onto the screen, they can easily clog the screen openings. Second, the free-fall design introduces randomness, which can lead to significant fluctuations in screening efficiency. When polyethylene wax particles flow into the screen surface at a non-constant flow rate, the thickness of the local material layer may vary, easily causing overload at the screen drop point and increasing the likelihood of agglomeration in that area. Utility Model Content

This device aims to solve the following problems inherent in existing technologies, where the feeding system typically employs an open, free-fall design and lacks a management structure: Firstly, because ultra-high molecular weight polyethylene wax is a material prone to agglomeration, multiple clumps may already exist before or during feeding. When these clumps fall onto the screen, they easily clog the screen openings. Secondly, the free-fall design introduces randomness, which leads to significant fluctuations in screening efficiency. When polyethylene wax particles flow into the screen surface at a non-constant flow rate, the thickness of the local material layer may vary, easily causing overload at the screen's discharge point and increasing the likelihood of agglomeration in that area.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention allows workers to feed polyethylene wax material through an externally equipped polyethylene wax conveying device, such as a conveyor belt, from the feed rack opening. The material first passes through two guide plates, and buffer blocks positioned above the guide plates slow down the material's feeding speed, preventing large-volume simultaneous feeding. These buffer blocks, along with guide rods, guide sleeves, springs, and other elastic components around the guide plates, not only prevent material from being blocked and accumulated but also utilize the elasticity and agitation properties of the buffer blocks to create a bumping and dispersing effect, effectively suppressing stickiness. The clumps of ultra-high molecular weight polyethylene wax material are then slowly broken up and fed into the area below the feeding frame. The operator starts the drive motor in advance to make the rotating rod and the inner rotating guide cylinder rotate along the guide ring cylinder. Since the inner rotating guide cylinder has a set metering groove around its perimeter, while the guide ring cylinder only has matching material grooves at the top and bottom, the inner rotating guide cylinder can carry the surrounding metering grooves to circulate and receive and discharge the same volume of material. The discharged material will fall onto the screening frame, effectively reducing the load on the screen frame's landing point, thus enabling the screening frame to perform the screening operation.

[0018] This utility model of screening frame can use the metal spiral composite springs and a set of screw-mounted vibrating motors on the outside of the main body to perform vibratory screening of materials. The qualified materials will be discharged along the discharge chute corresponding to the plate, while smaller materials will be screened onto the discharge plate and finally discharged through the discharge chute corresponding to the discharge plate.

[0026] This specific embodiment is a granulation and screening device for ultra-high molecular weight polyethylene wax, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the device includes a main body 1, with a screening mechanism 2 installed both internally and externally. A feeding rack 3 is fixed to one side of the upper part of the main body 1. A material feeding and metering mechanism 4 is installed inside and below the feeding rack 3. The screening mechanism 2 includes side fixing blocks 21, which are distributed on both sides of the main body 1. Metal spiral composite springs 22 are installed below the multiple side fixing blocks 21, and a base 23 is connected below the multiple metal spiral composite springs 22. Anchor bolts 24 are installed at the four corners of the base 23. A vibration motor 25 is screwed onto one side of the bottom of the main body 1. A screening mesh frame 26 is installed in the upper part of the interior of the main body 1, and a screening mesh frame 26 is installed in the lower part of the interior of the main body 1. The material discharge plate 27 and the discharge chute 28 are opened at different levels on both sides of the main body 1. The screening frame 26 and the material discharge plate 27 are distributed in opposite directions along different levels inside the main body 1. The screening frame 26 and the material discharge plate 27 are respectively connected to the bottom of the corresponding discharge chute 28 opened on both sides of the main body 1. The screening frame 26 can use the metal spiral composite spring 22 and a set of screw-mounted vibration motors 25 on the outside of the main body 1 to perform vibration screening of the material. The qualified material will be discharged along the corresponding discharge chute 28 of its plate, while the smaller material will be screened onto the material discharge plate 27 and finally discharged from the discharge chute 28 corresponding to the material discharge plate 27.

[0027] The material feeding mechanism 4 includes a material feeding component 41, which is installed in the upper part of the feed rack 3. The material feeding component 41 includes two sets of pre-set slots 411, which are respectively opened on the inner walls of the feed rack 3. A guide rod 412 is fixed in the middle of the two sets of pre-set slots 411. A guide sleeve 413 is movably guided around one end of the guide rod 412. Springs 414 are installed at both ends of the guide sleeve 413. A guide plate 415 is fixedly connected to the opposite end of each set of guide sleeves 413. Material feeding blocks 416 are provided above the two guide plates 415. There are two guide plates 415 vertically staggered along the inside of the feed rack 3. The length of the 15 varies. A metering component 42 is installed in the lower section of the feed rack 3. The metering component 42 includes guide plates 421, which are fixed to the lower sides of the feed rack 3. A set of guide ring cylinders 422 are connected to the ends of the two guide plates 421. A drive motor 423 is installed in the middle of one side of the set of guide ring cylinders 422. A rotating rod 424 is connected to one end of the drive motor 423. An inner rotating guide cylinder 425 is fixed around the rotating rod 424. The set of guide ring cylinders 422 and the inner rotating guide cylinder 425 are connected by a guide rotation connection. Metering grooves 426 are provided around the periphery of the inner rotating guide cylinder 425. The grooves on the upper and lower sides of the set of guide ring cylinders 422 are the same size as those around the inner rotating guide cylinder 425. The separately configured quantitative troughs 426 are matched in size. Workers can feed the polyethylene wax material from the opening of the feed rack 3 using an externally equipped polyethylene wax conveying device, such as a conveyor belt. The material will first pass through two guide plates 415. The buffer blocks 416 above the guide plates 415 can slow down the material feeding speed to a certain extent, preventing large-volume simultaneous feeding. The buffer blocks 416, together with the guide rods 412, guide sleeves 413, springs 414, and other elastic components distributed around the guide plates 415, not only prevent the material from being blocked and accumulated by the buffer blocks 416, but also utilize the elasticity and the agitation properties of the buffer blocks 416 to create a certain degree of bumping and scattering effect on the material, thereby effectively suppressing... The easily sticky ultra-high molecular weight polyethylene wax material clumps together, and then the material is slowly broken up and enters the area below the feed rack 3. The operator starts the drive motor 423 in advance to make the rotating rod 424 and the inner rotating guide cylinder 425 rotate along the guide ring cylinder 422. Since the inner rotating guide cylinder 425 is divided into measuring grooves 426 around its periphery, and the guide ring cylinder 422 is only provided with matching material grooves at the top and bottom, the inner rotating guide cylinder 425 can carry the surrounding measuring grooves 426 to circulate and reciprocate to receive and discharge the same volume of material. The discharged material will fall on the screening frame 26, effectively reducing the load on the landing point of the screening frame 26, and thus the screening frame 26 can achieve the screening operation of the material.

[0028] Working principle: Workers can feed polyethylene wax material from the opening of the feed rack 3 using an externally equipped polyethylene wax conveying device, such as a conveyor belt. The material will first pass through two guide plates 415. The buffer blocks 416 above the guide plates 415 can slow down the material feeding speed to a certain extent, preventing large-scale simultaneous feeding. The buffer blocks 416, together with the guide rods 412, guide sleeves 413, springs 414, and other elastic components around the guide plates 415, not only prevent the material from being blocked and accumulated by the buffer blocks 416, but also utilize the elasticity and the agitation of the buffer blocks 416 to create a certain degree of agitation and dispersion of the material, thereby effectively inhibiting the clumping of easily sticky ultra-high molecular weight polyethylene wax material. Then, the dispersed material will flow into the area below the feed rack 3. Workers will pre-start the drive motor 423 to rotate the rod 424 and the internal... The rotating guide cylinder 425 rotates along the guide ring cylinder 422. Since the inner rotating guide cylinder 425 has a set metering groove 426 around its periphery, and the set guide ring cylinder 422 only has matching material grooves at the top and bottom, the inner rotating guide cylinder 425 can carry the surrounding metering grooves 426 to circulate and receive and discharge materials of the same capacity. The discharged material will fall on the screening frame 26, effectively reducing the load on the landing point of the screening frame 26. Thus, the screening frame 26 can achieve the screening operation of the material. Secondly, the screening frame 26 can use the metal spiral composite spring 22 and a set of screw-mounted vibration motors 25 set on the outside of the main body 1 to perform vibration screening of the material. The qualified material will be discharged along the corresponding discharge groove 28 of its plate, while the smaller material will be screened onto the drop plate 27 and finally discharged by the discharge groove 28 corresponding to the drop plate 27.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features.
