Description

Technical Field

[0001] This utility model relates to the field of particle cleaning technology, specifically to a particle cleaning device for anti-aging plastic manufacturing. Background Technology

[0002] During the production and processing of anti-aging plastic granules, impurities such as dust, oil, and mold release agents easily adhere to the surface of the granules. If these impurities are not removed in time, they will not only affect the stability of subsequent injection molding, extrusion and other processing processes, leading to problems such as bubbles and defects in the products, but may also damage the anti-aging coating on the surface of the granules (such as hindered phenolic antioxidants, ultraviolet absorbers, etc.), reducing the anti-aging performance of the final product and shortening its service life.

[0003] Currently, existing plastic granule cleaning devices on the market have many shortcomings. Some devices use a single cleaning method, such as relying solely on agitation, which is insufficient to thoroughly remove tiny impurities from the granule surface crevices. Some devices cannot recycle their cleaning fluid, resulting in significant water waste and failing to meet the requirements of green production. Furthermore, some devices have poorly designed agitation structures that can easily damage the plastic granules during cleaning, and the installation and maintenance of components such as bearings are inconvenient, affecting the equipment's lifespan and operating efficiency. In addition, existing devices are ineffective in solid-liquid separation, leading to high granule moisture content and increased energy consumption for subsequent drying. Therefore, there is an urgent need for an anti-aging plastic granule cleaning device that can efficiently clean, protect granule properties, is energy-efficient and environmentally friendly, and is easy to maintain.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] In this technical solution, an anti-aging plastic manufacturing granule cleaning device includes a cleaning frame 1. A cleaning hopper 2 is mounted on the upper left side of the cleaning frame 1, and a vibrating frame 3 is mounted on the upper right side of the cleaning frame 1. A feeding plate 7 is mounted on the vibrating frame 3, and the end of the feeding plate 7 is located at the feeding end of the cleaning hopper 2. A stirring mechanism 9 is mounted at the center of the inside of the cleaning hopper 2. A circulating water pump 12 is mounted at the bottom of the cleaning hopper 2. Water pipes 13 are mounted at both the input and output ends of the circulating water pump 12. The water pipe 13 at the input end is connected to the drain end of the cleaning hopper 2, and the top end of the water pipe 13 at the output end is connected to the water inlet end of the cleaning hopper 2. A drain plate 10 is mounted at the bottom of the inside of the cleaning hopper 2, and the diameter of the drain holes of the drain plate 10 is smaller than the diameter of the plastic granules.

[0023] Structural Design: The cleaning frame 1, serving as the main load-bearing structure of the entire device, is welded from high-strength steel, such as Q345B material. It possesses excellent strength and toughness, capable of withstanding the stresses generated during the cleaning process, including those from the cleaning tank 2 and the vibrating frame 3. The entire frame undergoes surface rust prevention treatment, such as hot-dip galvanizing, achieving a zinc layer thickness of 80-100μm, effectively extending the equipment's service life and preventing rust and corrosion in humid environments.

[0024] Size Specifications: The dimensions of the cleaning rack 1 can be customized to suit different production scales and available space. Common small-sized equipment may be 1.5-2m long, 1-1.2m wide, and 1.2-1.5m high; medium-sized equipment can be 3-4m long, 1.5-2m wide, and 1.5-2m high; large-sized equipment is even larger. This size range can accommodate different production needs; small-sized equipment is suitable for laboratories or small-batch production, while medium and large-sized equipment are used in large-scale production workshops.

[0025] Installation method: The bottom of the cleaning frame 1 is designed with anchor bolt mounting holes. The frame is firmly fixed to the ground with anchor bolts to ensure the stability of the equipment during operation. During installation, a level must be used to level the frame, ensuring that the levelness error is within ±2mm, to prevent uneven distribution of cleaning fluid in the cleaning tank 2 due to frame tilt, which would affect the cleaning effect.

[0026] Material Selection: The cleaning tank 2 is made of stainless steel, such as 304 stainless steel, which has excellent corrosion resistance and can effectively resist the erosion of cleaning fluid, preventing impurities from being mixed into the plastic particles due to corrosion and affecting product quality. The thickness of the cleaning tank is generally 3-5mm, which ensures sufficient strength without increasing the weight and cost of the equipment due to excessive thickness.

[0027] Volume: The volume of the washing tank 2 depends on the processing capacity of the equipment. Small equipment may have a washing tank volume of 0.2-0.5 cubic meters, medium-sized equipment 0.5-1 cubic meters, and large equipment up to 1-2 cubic meters. A larger volume can accommodate more plastic granules for washing at once, improving production efficiency. For example, for small equipment with a processing capacity of 100-200 kg per hour, a 0.2 cubic meter washing tank can meet its washing requirements for 5-10 minutes, ensuring the continuity of the washing process.

[0028] Feeding end design: The feeding end of the washing hopper 2 is designed in a funnel shape, which increases the feeding area and facilitates the connection of the feeding plate 7 to the end, allowing plastic particles to enter the washing hopper more smoothly. The angle of the funnel is generally designed to be 30°-45°. This angle ensures smooth feeding without taking up too much space due to an excessively large angle.

[0029] Cleaning port supplement: The size of the cleaning port on the side wall of the cleaning tank 2 is determined by the volume and internal structure of the cleaning tank. Generally, the diameter of the cleaning port for small cleaning tanks may be 200-300mm, for medium-sized ones it is 300-400mm, and for large ones it can reach 400-500mm. The cleaning port adopts a circular design to facilitate the installation of the sealing plate 11. A rubber sealing gasket with a thickness of 5-8mm is used to seal between the sealing plate 11 and the cleaning port, providing good sealing performance and effectively preventing cleaning fluid leakage. The sealing plate 11 is fixed to the cleaning tank 2 with bolts. The number of bolts depends on the size of the cleaning port; generally, 4-6 bolts are used for small cleaning ports, 6-8 for medium ports, and 8-10 for large ports, ensuring that the sealing plate is firmly installed.

[0030] Vibration motor parameters: The model of the vibration motor 6 installed on the vibration frame 3 is selected according to the overall size of the equipment and the conveying requirements of the plastic granules. Common vibration motor power is between 0.2-2kW, and the excitation force is 1-10kN. For example, for small equipment, a vibration motor with a power of 0.2-0.5kW and an excitation force of 1-3kN can be selected; medium-sized equipment is suitable for a motor with a power of 0.5-1kW and an excitation force of 3-6kN; and large equipment requires a motor with a power of 1-2kW and an excitation force of 6-10kN. The frequency of the vibration motor is generally adjustable from 10-50Hz. By adjusting the frequency, the conveying speed of the plastic granules on the feed plate 7 can be controlled to match the washing speed of the washing hopper 2.

[0031] Vibration Frame Structure: The vibration frame 3 is welded from channel steel and angle steel, resulting in a stable structure. The specifications of the channel steel and angle steel are selected according to the size of the equipment. Small equipment can use #5 channel steel and #4 angle steel, medium equipment uses #8 channel steel and #5 angle steel, and large equipment uses #10 channel steel and #6 angle steel. The vibration frame 3 is connected to the cleaning frame 1 by shock-absorbing rubber pads. The thickness of the shock-absorbing rubber pads is 10-15mm, which can effectively reduce the vibration generated by the vibration motor during operation and transmit it to the cleaning frame, avoiding impact on other components and reducing noise during equipment operation.

[0032] Feed plate design: The feed plate 7 is installed on the vibrating frame 3, and its length is determined according to the distance between the vibrating frame and the washing hopper, generally between 0.5-1.5m. The width of the feed plate 7 is designed according to the flow rate of the plastic granules; the feed plate width is 0.2-0.3m for small equipment, 0.3-0.5m for medium equipment, and 0.5-0.8m for large equipment. The surface of the feed plate 7 is treated with anti-slip material, such as knurling, to increase the friction between the plastic granules and the feed plate and prevent the granules from slipping during conveying. The tilt angle of the feed plate 7 is adjustable, ranging from 10° to 30°. By adjusting the tilt angle, the conveying speed and flow rate of the granules can be controlled.

[0033] Motor Selection: Motor 14 provides power to the stirring mechanism 9. Its power is determined based on the volume of the washing hopper 2 and the stirring load. For a washing hopper with a volume of 0.2-0.5 cubic meters, a motor with a power of 0.5-1kW can be selected; for a volume of 0.5-1 cubic meters, a 1-2kW motor is required; and for a volume of 1-2 cubic meters, a 2-4kW motor is needed. The speed of motor 14 is generally between 100-300 rpm. The speed is reduced to a suitable stirring speed by a reducer. The reduction ratio of the reducer is determined based on the motor speed and stirring requirements, with common reduction ratios between 2 and 5.

[0034] Cleaning cylinder structure: The length of the cleaning cylinder 15 is slightly smaller than the inner diameter of the cleaning bucket 2, generally 0.8-0.9 times the inner diameter of the cleaning bucket, to ensure that the stirring plate 16 can effectively drive the movement of plastic particles and cleaning fluid inside the cleaning bucket when the cleaning cylinder rotates. The diameter of the cleaning cylinder 15 is designed according to the volume of the cleaning bucket and the stirring effect. The diameter of the cleaning cylinder corresponding to a small cleaning bucket may be 0.2-0.3m, medium 0.3-0.5m, and large 0.5-0.8m. The rotating shafts at both ends of the cleaning cylinder 15 are made of 45# steel, and after quenching and tempering, the hardness reaches HB220-250, improving the strength and wear resistance of the rotating shafts. The diameter of the rotating shafts is determined according to the size of the cleaning cylinder and the load, generally between 20-50mm.

[0035] Parameters for the agitator plates and water passages: The agitator plates 16 are installed evenly and equidistantly along the axis of the cleaning cylinder 15. The number is determined by the length and diameter of the cleaning cylinder. For small cleaning cylinders, the number of agitator plates may be 8-12; for medium-sized ones, 12-16; and for large ones, 16-20. The length of the agitator plate 16 is 0.6-0.8 times the radius of the cleaning cylinder, and the width is 50-100mm. The agitator plate 16 is made of the same material as the cleaning cylinder, stainless steel, and its surface is polished to reduce the adhesion of plastic particles during the agitation process. The water passages 17 are evenly and equidistantly opened on the outer wall of the cleaning cylinder 15. The diameter of the water passages is generally 5-10mm, and the number is determined by the surface area of ​​the cleaning cylinder. The number of water passages per square meter of surface area is between 50-100 to ensure that the cleaning fluid can circulate fully inside and outside the cleaning cylinder, enhancing the cleaning effect.

[0036] In some technical solutions, a bearing seat 8 is installed on one side wall of the top of the washing hopper 2, and a motor 14 is installed on the other side of the top of the washing hopper 2. The stirring mechanism 9 includes a cleaning cylinder 15, and a rotating shaft is installed at both ends of the cleaning cylinder 15. One rotating shaft is connected to the drive end of the motor 14, and the other rotating shaft is installed in the bearing seat 8.

[0037] Shaft Cylinder Structure and Dimensions: Shaft cylinders a81 and b82 are made of cast iron, possessing excellent wear resistance and vibration damping properties. The inner diameter of shaft cylinders a81 and b82 is determined based on the diameter of the rotating shaft, generally 2-3mm larger than the shaft diameter to ensure smooth shaft rotation. The outer diameter of the shaft cylinder is designed according to the installation space and load-bearing capacity; for small equipment, the outer diameter may be 50-80mm, for medium-sized 80-120mm, and for large 120-180mm. The length of the shaft cylinder is generally 1.5-2 times the outer diameter to ensure sufficient support length.

[0038] Design of fixing plate and connecting plate: Fixing plate 83 is welded to the rear side wall of shaft cylinder a81 and shaft cylinder b82, used to fix the bearing seat to the top of the cleaning bucket 2. The thickness of fixing plate 83 is 8-12mm, and the size is determined according to the size of the shaft cylinder and the number of mounting bolts. Connecting plate 18 is installed on the side walls of shaft cylinder a81 and shaft cylinder b82. The thickness of connecting plate is 6-10mm. The two shaft cylinders are connected together by bolts 20, which facilitates installation and disassembly. The diameter of bolt hole 19 is determined according to the specification of bolt 20, generally M8-M12.

[0039] Rotating cavity and ball bearing parameters: Rotating cavities 22 are evenly spaced along the inner walls of shaft cylinders a81 and b82. The diameter of the rotating cavity is generally 10-15mm, and the depth is 5-8mm. Ball bearings 23 are installed inside the rotating cavities. The diameter of the balls is 8-12mm, and the material is bearing steel with a hardness of HRC60-65. The balls 23 are fitted into the rotating shaft. When the rotating shaft rotates, the balls roll inside the rotating cavity, greatly reducing the friction between the rotating shaft and the shaft cylinder, and improving the rotational efficiency of the stirring mechanism. The number of balls in the rotating cavity is determined according to the size of the rotating cavity; generally, 4-6 balls are installed in each rotating cavity.

[0040] Oil injection hole design: Oil injection hole 21 is located on the outer wall of shaft cylinder a81 and shaft cylinder b82, and communicates with rotating cavity 22. The diameter of the oil injection hole is generally 5-8mm, used to inject lubricating oil into the rotating cavity to ensure good lubrication of the balls. A plug is inserted into the oil injection hole 21. The plug is made of rubber material, which has good sealing performance and can prevent dust and impurities from entering the oil injection hole, while avoiding lubricating oil leakage. During equipment operation, lubricating oil is injected into the rotating cavity periodically through the oil injection hole, generally once every 200-300 hours of operation, which can effectively extend the service life of the bearing housing.

[0041] Water pump selection: The circulating water pump 12 is selected based on the volume of the cleaning tank 2 and the required circulation flow rate of the cleaning fluid. For small cleaning tanks, a water pump with a flow rate of 5-10 cubic meters per hour and a head of 10-15 meters can be selected; for medium-sized cleaning tanks, a water pump with a flow rate of 10-20 cubic meters per hour and a head of 15-20 meters is suitable; for large cleaning tanks, a water pump with a flow rate of 20-30 cubic meters per hour and a head of 20-25 meters is required. The circulating water pump 12 is made of stainless steel or engineering plastic to resist corrosion from the cleaning fluid.

[0042] Water pipe specifications: Water pipe 13 connects the input / output ends of the circulating water pump 12 to the drain and inlet ends of the cleaning tank 2. Water pipe 13 is made of PVC material, which has good corrosion resistance and aging resistance. The pipe diameter is determined according to the pump flow rate; generally, the pipe diameter is 25-32mm for small equipment, 32-50mm for medium equipment, and 50-75mm for large equipment. During installation, water pipe 13 must be securely connected and well-sealed. Rubber sealing rings and pipe clamps can be used for connection to prevent cleaning fluid leakage. At the same time, excessive bending of the water pipe should be avoided; the bending radius should generally not be less than 5 times the pipe diameter to reduce water flow resistance and ensure smooth circulation of the cleaning fluid.

[0043] In some technical solutions, stirring plates 16 are evenly and equidistantly installed on the outer wall of the cleaning cylinder 15 along its axis, and water passage holes 17 are evenly and equidistantly opened on the outer wall of the cleaning cylinder 15.

[0044] In some technical solutions, the bearing housing 8 includes a shaft cylinder a81 and a shaft cylinder b82 arranged opposite to each other. A fixing plate 83 is installed on the rear side wall of both shaft cylinder a81 and shaft cylinder b82, and the fixing plate 83 is installed at the top of the cleaning bucket 2. Rotating cavities 22 are evenly and equidistantly opened on the inner wall of shaft cylinder a81 and shaft cylinder b82 along their axis. Ball bearings 23 are installed inside the rotating cavity 22 and are fitted to the rotating shaft.

[0045] In some technical solutions, connecting plates 18 are installed on both side walls of shaft cylinder a81 and shaft cylinder b82. The side walls of the connecting plates 18 are provided with screw holes 19, and bolts 20 are screwed into the inside of the screw holes 19. Oil injection holes 21 are provided on the outer walls of shaft cylinder a81 and shaft cylinder b82. The oil injection holes 21 are connected to the rotating cavity 22, and a plug is inserted into the oil injection holes 21.

[0046] In some technical solutions, a vibration motor 6 is installed on the vibration frame 3.

[0047] In some technical solutions, the side wall of the cleaning tank 2 is provided with a cleaning port, and a sealing plate 11 is installed at the cleaning port.

[0048] Material and Dimensions of the Drainage Board: The drainage board 10 is made of stainless steel, such as 304 stainless steel, with a thickness of 2-3mm. The dimensions of the drainage board are determined based on the internal dimensions of the washing hopper 2, slightly smaller than the inner diameter of the washing hopper, with a 5-10mm gap maintained between the board and the inner wall of the washing hopper for easy installation and drainage. For example, for a washing hopper with an inner diameter of 0.5m, the diameter of the drainage board can be 0.48m.

[0049] Drainage hole parameters: The diameter of the drainage holes on the drainage board 10 is smaller than the diameter of the plastic granules to ensure that the plastic granules do not leak through the drainage holes. Generally, for common anti-aging plastic granules with a particle size of 2-5mm, the drainage hole diameter can be designed to be 1-1.5mm. The drainage holes are evenly distributed on the drainage board, with 10,000-15,000 drainage holes per square meter of drainage board area to ensure sufficient drainage speed, allowing excess cleaning liquid to be quickly discharged from the cleaning hopper through the drainage board, improving cleaning efficiency. At the same time, the surface of the drainage board can be frosted to increase the friction between the plastic granules and the drainage board, preventing the granules from sliding during the drainage process.

[0050] Working process and principle:

[0051] Work process

[0052] Feeding stage: The operator places the anti-aging plastic granules to be cleaned on the feed plate 7 of the vibrating frame 3 and starts the vibration motor 6 on the vibrating frame 3. The excitation force generated by the vibration motor 6 is transmitted to the vibrating frame 3 and the feed plate 7, causing the feed plate 7 to vibrate. Because the feed plate 7 has an inclination angle of 10°-30° and its surface is knurled for anti-slip treatment, the plastic granules move along the feed plate 7 towards the feed end of the cleaning hopper 2 under the combined action of vibration and gravity, and enter the interior of the cleaning hopper 2 through the funnel-shaped opening at the feed end of the cleaning hopper 2.

[0053] Cleaning Stage: After the plastic granules enter the cleaning hopper 2, the motor 14 and the circulating water pump 12 are started. The motor 14 drives the cleaning cylinder 15 of the stirring mechanism 9 to rotate, and the stirring plate 16 on the outer wall of the cleaning cylinder 15 rotates accordingly, stirring the plastic granules and cleaning liquid in the cleaning hopper 2, so that the plastic granules and cleaning liquid are in full contact. At the same time, the circulating water pump 12 draws the cleaning liquid from the bottom of the cleaning hopper 2 out through the water pipe 13 at the input end, and then sends it back to the water inlet end of the cleaning hopper 2 through the water pipe 13 at the output end, forming a circulating flow of the cleaning liquid. Under the action of stirring and the circulation of the cleaning liquid, impurities on the surface of the plastic granules are gradually removed.

[0054] Draining stage: After cleaning for a period of time, turn off motor 14 and circulating water pump 12. The plastic particles in the cleaning bucket 2 fall onto the drain plate 10 under gravity. Since the diameter of the drain holes of the drain plate 10 is smaller than the diameter of the plastic particles, the cleaning liquid flows to the bottom of the cleaning bucket 2 through the drain holes, while the plastic particles remain on the drain plate 10, achieving solid-liquid separation.

[0055] Discharge and Cleaning: Open the discharge port of washing hopper 2 (if there is a specially designed discharge structure) and remove the drained plastic granules. After the equipment has been used for a period of time, the sealing plate 11 at the cleaning port on the side wall of washing hopper 2 can be opened to clean the inside of washing hopper 2 to prevent impurities from accumulating and affecting the subsequent cleaning effect.

[0056] Working principle

[0057] Vibration conveying principle: When the vibrating motor 6 is working, it generates periodic excitation force, causing the vibrating frame 3 and the feed plate 7 to perform simple harmonic motion. This vibration gives the plastic granules a certain amount of kinetic energy, overcoming the static friction between the granules and the feed plate, thus moving them forward along the inclined feed plate. By adjusting the frequency of the vibrating motor, the vibration intensity of the feed plate can be changed, thereby controlling the conveying speed of the plastic granules to match the cleaning capacity of the washing tank.

[0058] Stirring and cleaning principle: Motor 14 drives the cleaning cylinder 15 and stirring plate 16 to rotate. During rotation, the stirring plate 16 applies a thrust to the plastic particles and cleaning liquid, causing the plastic particles to undergo complex movements in the cleaning liquid, including translation, rotation, and collision. This movement generates relative friction between the surface of the plastic particles and the cleaning liquid, while friction and collision also occur between the particles themselves, thereby peeling off impurities from the particle surface and dispersing them into the cleaning liquid. The water passage 17 on the cleaning cylinder 15 allows the cleaning liquid to flow freely inside and outside the cleaning cylinder, ensuring uniform distribution of the cleaning liquid and sufficient contact with the particles, thus enhancing the cleaning effect.

[0059] Circulation cleaning principle: The circulating water pump 12 provides power for the circulation of the cleaning fluid, causing the cleaning fluid to flow continuously in the closed loop formed by the cleaning tank 2 and the water pipe 13. The flowing cleaning fluid can promptly carry away the detached impurities, preventing them from re-adhering to the particle surface. At the same time, it also keeps the concentration of the cleaning fluid in different areas of the cleaning tank uniform, improving the overall cleaning efficiency.

[0060] Drainage separation principle: The drain plate 10 utilizes gravity and screen filtration to achieve solid-liquid separation. The washed plastic particles and cleaning liquid mixture fall onto the drain plate under gravity. The liquid can permeate through the drain holes to the bottom, while the solid particles, being larger than the diameter of the drain holes, are retained on the drain plate. This achieves separation of the plastic particles and the cleaning liquid, reducing the burden of subsequent drying processes.
