Description

Technical Field

[0001] This utility model relates to the field of plastic raw material processing technology, specifically a pretreatment device for modified engineering plastic raw materials. Background Technology

[0002] Modified engineering plastic raw materials are polymeric materials that use traditional engineering plastics such as polyamide and polycarbonate as the base material and improve their performance by adding functional additives or using composite modification technology. In the early stage of production and processing, the plastic raw materials need to be cleaned to remove powder stains and other contaminants from the surface of the plastic raw materials, so as to ensure that the raw materials have higher purity and quality, which helps to improve the performance and quality of the final product.

[0003] An investigation revealed that a Chinese utility model patent discloses a plastic raw material pretreatment device (publication number: CN223044915U), which includes a cleaning component. The cleaning component includes a driving component, a filter cartridge, a box cover, a round tube, a stirring rod, a water inlet pipe, and a water outlet component. The box is the basic structure of the entire device, providing space for the installation and support of other components. It is also a container for holding cleaning water and provides power for the rotation of the filter cartridge. By driving the filter cartridge to rotate, the plastic raw material inside the filter cartridge can fully contact the water and the stirring rod, which helps to improve the cleaning effect. After cleaning, the water is discharged through the water outlet component. The filter cartridge continues to rotate to shake the water attached to the raw material out of the filter cartridge and then discharge it through the water outlet component. The function of the water inlet pipe is to inject cleaning water into the box to provide the necessary liquid environment for cleaning the plastic raw material. The round tube is used to add the plastic raw material to be treated.

[0004] Although the aforementioned patent can clean the plastic material inside the filter cartridge by contact with water, the plastic material is still in contact with sewage after cleaning. Even if the surface residual water is removed by subsequent swiping, the swiping can only remove the water from the surface of the outer plastic material, and the surface of the inner plastic material will still have stains, thereby reducing the cleaning effect of the plastic material.

[0005] Therefore, this utility model provides a modified engineering plastic raw material pretreatment device to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides a pretreatment device for modified engineering plastic raw materials, which aims to solve the problems mentioned in the background art.

The outer wall of the main shaft is fixedly connected to an auger blade via a bracket, and the outer wall of the auger blade is in contact with the inner wall of the cleaning cylinder.

[0008] As a preferred technical solution of this application, the length of the water tank is greater than the length of the cleaning cylinder, the high-pressure nozzle is used for rinsing the plastic raw materials inside the cleaning cylinder, and the inner wall of the vertical end of the protective cover is at the same horizontal plane as the inner wall of the water tank.

[0014] (III) Beneficial Effects The beneficial effects of this application are as follows: This invention utilizes a lifting washing cylinder design. During the initial rough washing of plastic materials, the washing cylinder is positioned inside the water tank, in contact with the water source. This, combined with the operation of the stirring component, causes the plastic materials inside the washing cylinder to reciprocate, achieving frictional cleaning of the plastic material's surface. During the fine washing, the washing cylinder rises, and high-pressure nozzles spray clean water to further clean the plastic materials inside the washing cylinder, removing any residual wastewater adhering to the surface, thereby improving the cleaning quality of the plastic materials. The stirring component, through the rotation of hollow auger blades, propels and stirs the plastic materials, improving cleaning efficiency through friction between the materials. Simultaneously, the rotation of the auger blades pushes the plastic materials out of the washing cylinder, facilitating rapid unloading.

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.

[0017] like Figure 1-4As shown, this utility model provides a pretreatment device for modified engineering plastic raw materials, including a water tank 1, a protective cover 11 above the water tank 1, and a high-pressure nozzle 12 penetrating through the central array of the protective cover 11; a lifting assembly 2, which is located above the protective cover 11, and the telescopic end of the lifting assembly 2 extends through to the lower part of the protective cover 11 and is fixedly connected to a washing cylinder 3; and a stirring assembly 4, which includes a main shaft 44, both ends of which are rotatably connected to the washing cylinder 3 via ball bearings. The outer wall of the main shaft 44 is fixedly connected to an auger blade 45 via a bracket, and the outer wall of the auger blade 45 is in contact with the inner wall of the washing cylinder 3. The lifting assembly 2 controls the lifting of the washing cylinder 3, thereby allowing the plastic raw materials inside the washing cylinder 3 to be distributed in different positions under different cleaning conditions. Thus, the washing efficiency of the plastic raw materials is improved through the spray-type fine washing setting.

[0018] Furthermore, the length of the water tank 1 is greater than the length of the cleaning cylinder 3. The high-pressure nozzle 12 is used to rinse the plastic raw materials inside the cleaning cylinder 3. The inner wall of the vertical end of the protective cover 11 is at the same level as the inner wall of the water tank 1. The water inlet end of the high-pressure nozzle 12 is connected to the cleaning water supply pipe. The plastic raw materials inside the cleaning cylinder 3 are rinsed by spraying clean water.

[0019] Furthermore, the lifting assembly 2 includes a support plate 21, which is fixedly connected to the upper surface of the protective cover 11. A first cylinder 22 is fixedly connected to the upper surface of the support plate 21. The lifting end of the first cylinder 22 extends through the interior of the protective cover 11 and is fixedly connected to a connecting frame 23. A guide shaft 24 is fixedly connected to the upper surface of the connecting frame 23 and extends through the upper part of the support plate 21. Two sets of lifting assemblies 2 are provided, and the two sets of lifting assemblies 2 are symmetrically distributed on both sides of the cleaning cylinder 3. The lifting assembly 2 is used to adjust the height of the cleaning cylinder 3. The connecting frame 23 is fixedly connected to both sides of the cleaning cylinder 3 by flange. By starting the first cylinder 22, the connecting frame 23 is adjusted up and down, which in turn adjusts the cleaning cylinder 3 up and down. Thus, different cleaning states can be achieved by distributing the cleaning cylinder 3 at different positions.

[0020] Furthermore, a feed pipe 31 and a discharge port 32 are provided on one side of the cleaning cylinder 3. A baffle 33 is provided at the end of the cleaning cylinder 3 corresponding to the discharge port 32, and the lifting end of the second cylinder 34 is fixedly connected to the upper surface of the baffle 33. A limit plate 35 and a positioning plate 36 are fixedly connected to the end of the cleaning cylinder 3. The limit plate 35 is symmetrically engaged on both sides of the baffle 33. The cross-section of the limit plate 35 is L-shaped. The second cylinder 34 is fixedly connected to the upper surface of the positioning plate 36. A guide rod is also fixedly connected to the upper surface of the baffle 33, and the guide rod extends through to the top of the positioning plate 36. The baffle 33 is used to control the opening and closing of the discharge port 32. By starting the second cylinder 34, the baffle 33 is adjusted up and down, which can control the opening and closing of the discharge port 32. When the cleaning cylinder 3 is cleaning plastic raw materials, the discharge port 32 is closed, and conversely, the discharge port 32 is opened to realize the discharge of plastic raw materials.

[0021] Furthermore, the stirring assembly 4 also includes a first motor 41, which is fixedly connected to the outer wall of a set of connecting frames 23. The output end of the first motor 41 is fixedly connected to a first gear 42, and a second gear 43 meshes with the outside of the first gear 42. The center of the second gear 43 is fixedly connected to a main shaft 44. The first motor 41 drives the first gear 42 to rotate, and the second gear 43 drives the main shaft 44 and the auger blades 45 to rotate. The first motor 41 rotates forward a certain number of times and then reverses. Through the cooperation of forward and reverse rotation, the plastic material inside the washing cylinder 3 is reciprocated and agitated, thereby improving the cleaning efficiency of the plastic material. When feeding, the continuous rotation of the auger blades 45 pushes the plastic material inside the washing cylinder 3 to the lower feed port 32, thereby realizing the feeding of the plastic material.

[0022] Working principle: First, an appropriate amount of plastic raw material is added into the cleaning cylinder 3 through the feed pipe 31. Then, by activating the lifting component 2, the bottom of the cleaning cylinder 3 is immersed in the water source of the water tank 1. Then, by driving the stirring component 4, the auger blades 45 rotate in both directions, which agitates the plastic raw material inside the cleaning cylinder 3. Combined with the water source, the plastic raw material is thoroughly cleaned. Then, by lifting the lifting component 2, the cleaning cylinder 3 is moved upward, and clean water is sprayed through the high-pressure nozzle 12 to further rinse the plastic raw material inside the cleaning cylinder 3, thereby improving the cleaning efficiency of the plastic raw material and reducing surface stains.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
