Description

Technical Field

[0001] The utility model relates to the technical field of plastic extruders, in particular to a cooling water tank for granulation with a vibration dewatering function. Background Art

[0002] Plastic extrusion strand pelletizing is a plastics processing process that typically includes pretreatment of the raw plastic, melting, extrusion, cooling, and shaping. During the extrusion process, the raw plastic is squeezed and heated by the extruder's screw, melting it into a uniform melt. Under pressure, it is extruded through a die into the desired profile. The extruded profile requires cooling and water removal. Cooling allows the molten plastic to solidify quickly, maintaining its extruded shape; water removal prevents residual moisture from adversely affecting the plastic product, such as reducing strength and affecting appearance. Therefore, developing efficient and reliable plastic extrusion water removal equipment is crucial for improving product quality and production efficiency.

[0003] Traditional cooling water troughs usually use mechanical devices such as scrapers and water absorption strips to scrape or absorb moisture on the surface of the profile, but there may be problems with incomplete water removal and poor water removal effect, especially for tiny water droplets on the surface of the profile or moisture that penetrates into the interior of the profile, which are difficult to completely remove. If the water on the surface of the strip is not completely removed, it will affect the subsequent normal use of the granulation material.

[0004] A "plastic strip dewatering system" disclosed in Chinese patent literature, with the public number CN202284885U, includes a cooling water trough filled with cooling water, a brush, and a blower. The plastic strips are dewatered and dried by passing through the cooling water trough, the brush, and the blowing and suction ports of the blower in sequence. The device does not have the function of circulating cooling water, and its transmission wheel is single, resulting in low cooling efficiency. Summary of the Invention

[0005] The utility model mainly solves the problems of incomplete water removal in the cooling water trough, poor water removal effect and complicated water removal equipment, and proposes a cooling water trough for granulation with a vibration water removal function, which has high water removal efficiency and simple equipment; a further purpose of the utility model is to solve the problem that the existing cooling water trough cannot realize the water circulation function. In the utility model, the cooling water falling after the water removal roller will flow back into the water storage tank, which is conducive to maintaining a good production site environment.

[0006] In order to achieve the above objectives, the following technical solutions are proposed:

[0007] A cooling water trough for granulation with a vibration dewatering function comprises a main trough body and a bracket, wherein the main trough body is fixedly mounted on the bracket, the main trough body comprises a water receiving tray and a dewatering roller, the main trough body is provided with a water inlet and a water outlet, the dewatering roller is provided with a vent, the dewatering roller is fixed above the water receiving tray, and the dewatering roller is a regular polygon structure with at least three sides.

[0008] The plastic strips first pass through the scraping brush, which scrapes off the moisture on the surface of the strips as they pass through, performing a preliminary dewatering operation on the strips; secondly, when the strips pass through the dewatering roller, they come into contact with its edges and generate vibration, further dewatering the strips; at the same time, air vents are provided on the rotating shaft of the dewatering roller, which can blow drying gas toward the plastic strips, thereby enhancing the dewatering effect; in addition, the water receiving tray is connected to the dewatering roller, and the cooling water that falls after passing through the dewatering roller will flow back into the main tank, which is conducive to maintaining a good production site environment.

[0009] Preferably, the dewatering roller is fixed above the water receiving tray to effectively collect and guide the water dripping from the material to prevent it from splashing everywhere, thereby keeping the working environment clean and tidy. The dewatering roller is a regular polygon structure with at least 3 sides. When the pull rod passes through the dewatering roller, the edge of the dewatering roller will cause the plastic pull rod to vibrate, thereby causing the water droplets attached to the surface of the pull rod to drip onto the water receiving tray.

[0010] Preferably, the water receiving tray is located on one side of the water inlet, and the end of the water receiving tray is inclined at 45 to 60 degrees to the main tank body, ensuring that the cooling water falling after the dewatering roller vibrates can flow smoothly along the surface of the water receiving tray and finally gather into the water storage tank in the main tank body.

[0011] Preferably, a water storage tank is provided in the main tank body, and the water storage tank is used to hold cooling water. An overflow port is provided in the water storage tank, and the overflow port is connected to the water outlet. When the water level in the water storage tank reaches a preset height, excess water will be automatically discharged through the overflow port, avoiding the adverse effects of water overflow on the system, simplifying the drainage process, and improving the degree of automation of the system, reducing the need for manual intervention.

[0012] Preferably, the water tank is provided with at least one scraping brush to further improve the water removal effect. The scraping brush is arranged along the width direction of the water tank. The scraping brush is located near the water removal roller and can scrape off the residual water on the surface of the pull strip again when the pull strip passes by. The scraping brush is soft and elastic, which can effectively remove water from the surface of the pull strip without causing damage to the pull strip.

[0013] Preferably, the main trough body is provided with no less than 3 groups of guide rollers for transmitting the pull strips. The two ends of the guide rollers are fixed on both sides of the water storage tank to form a stable transmission channel to ensure the smoothness and continuity of the material during the transmission process; the rolling design of the guide rollers can reduce the friction between the pull strips and the main trough body, reduce the transmission resistance, and improve the transmission efficiency; in addition, the layout of multiple groups of guide rollers can also be adjusted according to the characteristics of the material and the transmission requirements to meet the usage requirements in different scenarios.

[0014] Preferably, the dewatering roller is provided with a plurality of air holes, which are circular and evenly opened on the side of the dewatering roller. Dry gas can be blown toward the direction of the pulling strips to accelerate the evaporation and diffusion of moisture on the surface of the material. The heat generated when the dewatering roller is running can also be discharged from the air holes, which not only improves the dewatering efficiency of the dewatering roller, but also enhances its heat dissipation performance and extends the service life of the roller body. In addition, the air holes can also reduce the adhesion between the roller body and the pulling strips to a certain extent, making the dewatering process smoother.

[0015] Preferably, the water inlet is arranged at one end near the water removal roller, and the water outlet is arranged at the starting end along the direction of the strip transmission, so that the strip is fully cooled and the cooling effect is enhanced. Moreover, since the cooling water collected by the water receiving tray will converge on one side of the water inlet of the water storage tank, the cooling water collected by the water receiving tray can be discharged together when the cooling water is replaced or discharged. At the same time, the water inlet and the water outlet help to maintain the temperature of the cooling water. When the water temperature is higher than the temperature required for cooling the strip, the cooling water is transported by the water inlet, which can ensure the cooling effect and improve the cooling efficiency.

[0016] Preferably, the bottom of the water storage tank is connected to the water receiving tray on a side higher than the side of the water outlet, so that the cooling water received by the water receiving tray flows smoothly into the water storage tank to avoid accumulation and re-wetting of the pull strips.

[0017] The beneficial effects of the utility model are as follows: the utility model is a cooling water trough for granulation with a vibration dewatering function, which is a polygonal dewatering roller and a water receiving tray at the terminal end of the existing conventional cooling water trough; it includes a main trough body and a bracket, the main trough body is fixedly installed on the bracket, the main trough body includes a water receiving tray and a dewatering roller, the main trough body is provided with a water inlet and a water outlet, the side of the dewatering roller is provided with an air vent, the dewatering roller is fixed above the water receiving tray, the dewatering roller is a regular polygon structure with at least 3 sides, the plastic pull rod will vibrate up and down when passing through the dewatering roller, thereby enhancing the dewatering effect on the surface of the pull rod, and at the same time, an air vent is provided on the rotating shaft of the dewatering roller, which can blow drying gas in the direction of the plastic pull rod, further enhancing the dewatering effect, the water receiving tray is connected to the dewatering roller, and the cooling water falling after passing through the dewatering roller will flow back into the water storage tank, which is beneficial to maintaining a good production site environment.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The specific embodiments of the present utility model are as follows.

[0023] The utility model discloses a cooling water trough for granulation with a vibration dewatering function, comprising a main trough body 1 and a bracket 7, wherein the main trough body 1 is fixedly mounted on the bracket 7, the main trough body 1 comprises a water receiving tray 6 and a dewatering roller 5, the main trough body 1 is provided with a water inlet 8 and a water outlet 9, the rotating shaft of the dewatering roller 5 is provided with an air vent 11, a water storage tank 10 is provided inside the main trough body 1, an overflow port 3 is provided inside the water storage tank 10, the overflow port 3 is connected to the water outlet 9, and the main trough body 1 is also provided with a There is a scraper brush 4, and the two ends of the scraper brush 4 are fixed on both sides of the water storage tank 10; when the plastic pull rod passes through the dewatering roller 5, it will vibrate up and down, thereby enhancing the dewatering effect on the surface of the pull rod. At the same time, the dewatering roller 5 is provided with an air vent 11, which can blow drying gas in the direction of the plastic pull rod, further enhancing the dewatering effect. The water receiving tray 6 is connected to the dewatering roller 5, and the cooling water falling after passing through the dewatering roller 5 will flow back into the main tank, which is beneficial to maintaining a good production site environment; the dewatering roller 5 is a regular prism structure with at least 3 edges.

[0024] The main tank body 1 is located above the bracket 7. The main tank body 1 is rectangular. A water storage tank 10 is provided in the main tank body 1. An overflow port 3 is provided in the water storage tank 10. A water inlet 8 and a water outlet 9 are respectively provided on both sides of the bottom of the main tank body 1, and the water outlet 9 is communicated with the overflow port 3; a water receiving tray 6 is provided on one side of the main tank body 1. The water receiving tray 6 is inclined at 45 to 60 degrees and is fixedly connected to one side of the main tank body 1. A dewatering roller 5 is provided on the water receiving tray 6. The dewatering roller 5 is located above the water receiving tray 6 and has a through hole; a wiper brush 4 is also provided on the side of the main tank body 1 near the dewatering roller 5, and both ends of the wiper brush 4 are fixed on both sides of the water storage tank 10; at least three groups of guide rollers 2 are provided above the water storage tank 10. The length of the guide roller 2 is the same as the width of the water storage tank 10, and the two ends of the guide roller 2 are fixed on both sides of the guide roller 2.

[0025] The main tank body 1 is supported and fixed by no less than 3 solid brackets 7 at the bottom to ensure that it can maintain stable operation during use. The brackets 7 are evenly distributed at the bottom of the main tank body 1, which not only effectively disperses the weight load of the main tank body 1, but also greatly enhances the overall stability and safety; the brackets 7 are made of high-strength materials and can withstand forces from all directions, providing solid support and protection for the main tank body 1, ensuring the reliability and safety of the long-term operation of the equipment.

[0026] The main tank body 1 is used to carry and fix the main components for cooling. Cooling water for cooling the pull rods is usually placed inside the main tank body 1. After the particles are extruded or cut, the heat on the surface of the particles is quickly taken away, so that the particles are quickly cooled and solidified to achieve the required physical and chemical properties. In addition, the size and shape of the main tank body 1 can be adjusted according to actual usage and the specifications of the cooling devices.

[0027] The water storage tank 10 is located inside the main tank body 1 and is used to hold cooling water to cool and solidify the particles. The bottom of the water storage tank 10 is connected to the water receiving tray 6 on a side higher than the side of the water outlet 9, so that the cooling water received by the water receiving tray 6 can be smoothly integrated into the water storage tank 10, effectively avoiding the accumulation of cooling water during the integration process due to uneven flow rate or change in direction; the accumulated cooling water will not only reduce the water removal efficiency, but may also re-contact the particles that have been initially cooled by infiltration or sputtering, resulting in the problem of "strand re-wetting", thereby affecting the final quality of the strands; the water storage tank 10 realizes the smooth flow and efficient use of cooling water, which provides a strong guarantee for the stable operation of the granulation production line and the continuous improvement of product quality.

[0028] At least three groups of guide rollers 2 are provided above the water tank 10. The length of the guide rollers 2 is the same as the width of the water tank 10, ensuring that the guide rollers 2 can completely cover the area above the water tank 10 and achieve comprehensive guidance of the flow of particles. The two ends of the guide rollers 2 are fixed to the two sides of the guide rollers 2 to provide stable support for the guide rollers 2, and a distance is maintained between the guide rollers 2 and the water tank 10 to prevent corrosion caused by the cooling water. The guide rollers 2 are used to conduct and control the high-temperature strands discharged from the granulator, ensuring that they can pass through the water tank 10 evenly and stably, allowing the cooling water to cool and solidify them, and carry out subsequent cooling treatment. Through the guidance of the guide rollers 2, the flow of particles becomes more controllable, effectively avoiding the splashing and accumulation caused by the strands directly impacting the water surface of the water tank 10, thereby reducing the waste of cooling water, pollution to the surrounding environment, and damage to the cooling equipment.

[0029] The water inlet 8 is arranged at one end near the dewatering roller 5, and the water outlet 9 is arranged at the starting end along the direction of the strip transmission, so that the strip can be fully cooled and the cooling effect is enhanced. Moreover, since the cooling water collected by the water receiving tray 6 will converge on one side of the water inlet 8 of the water storage tank 10, the cooling water collected by the water receiving tray 6 can be discharged together when the cooling water is replaced or discharged, thereby improving the cooling water circulation efficiency. At the same time, the water inlet 8 and the water outlet 9 help to maintain the temperature of the cooling water. As the strips continue to enter the cooling area and release heat, the cooling water temperature gradually increases, which will further affect the subsequent cooling and solidification effect of the strips. By setting the water inlet 8 to a controllable flow rate, when it is detected that the water temperature is higher than the temperature required for the strip cooling, the input amount of cooling water can be automatically increased, thereby quickly lowering the water temperature and ensuring the cooling effect of the strips. This not only improves production efficiency, but also reduces the need for human intervention, reduces the difficulty of operation and the error rate.

[0030] Overflow port 3 is disposed within water storage tank 10 and communicates with water outlet 9. When the water level within water storage tank 10 gradually rises with the continuous injection of cooling water and reaches a predetermined safe height, excess water, under the action of gravity, flows along the channel of overflow port 3 toward water outlet 9 and is ultimately discharged from the system through water outlet 9. This avoids problems such as equipment damage, production interruption, and environmental pollution that could result from water overflow, simplifies the drainage process, improves the system's degree of automation, and reduces the need for manual intervention.

[0031] The wiper brush 4 is arranged above the water tank 10, and the wiper brush 4 is arranged along the width direction of the water tank 10, ensuring that it can fully cover and effectively act on the entire width range of the pull strip, avoiding dead corners of residual moisture; the wiper brush 4 is located near the dewatering roller 5, so that after the pull strip passes through the dewatering roller 5 for preliminary dewatering, the residual moisture on the surface of the pull strip can be scraped off by the wiper brush 4, and further water can be removed, achieving a double dewatering effect. The wiper brush 4 is soft and elastic, which can effectively remove moisture from the surface of the pull strip without causing damage to the pull strip; at the same time, the wiper brush 4 is easy to replace to ensure the dewatering effect and reliability.

[0032] The water receiving tray 6 is inclined at 45 to 60 degrees on the main tank body 1 and is located on the side of the water inlet 8 of the main tank body 1, ensuring that the cooling water falling after the dewatering roller 5 vibrates can flow smoothly along the surface of the water receiving tray 6 and finally gather in the water storage tank 10 in the main tank body 1, thereby maximizing the flow efficiency and recovery effect of the cooling water. When the cooling water circulates in the water storage tank 10, it can flow to the water outlet 9 together with the cooling water input from the water inlet 8 and be discharged from the water outlet 9 to circulate the cooling water and maintain its temperature to meet the cooling and solidification needs of the pull rods.

[0033] The dewatering roller 5 is arranged on the water receiving tray 6 and is located above the water receiving tray 6. The water receiving tray 6 can effectively receive the water naturally dripping from the guide roller 2, so that the dripping cooling water is gathered into the water storage tank 10 along the inclined direction of the water receiving tray 6, thereby avoiding water splashing everywhere and keeping the production environment clean and dry; the dewatering roller 5 is a regular polygon structure with at least 3 sides. When the pull rod passes through the dewatering roller 5, the edges of the dewatering roller 5 will cause the plastic pull rod to vibrate, causing the water droplets attached to the surface of the pull rod to lose adhesion and drip onto the water receiving tray 6 below, thereby improving the dewatering effect and allowing the cooling water to reflux, reducing resource waste.

[0034] The air vent 11 is opened on the side of the dewatering roller 5, which can blow dry gas in the direction of the strip. When the strip passes through the dewatering roller 5, the dry gas quickly wraps and penetrates the surface of the strip, accelerating the evaporation and diffusion process of water molecules from the surface of the material, thereby significantly improving the dewatering efficiency; the heat accumulated inside the dewatering roller 5 is quickly dissipated to the external environment through the action of the air flow, thereby maintaining the appropriate working temperature of the roller body, which not only improves the dewatering efficiency of the dewatering roller 5, but also enhances its heat dissipation performance and extends the service life of the roller body; at the same time, the air vent 11 can also reduce the adhesion between the roller body and the strip to a certain extent, making the dewatering process smoother; in addition, an independent blowing device can be used to further enhance the drying effect of the strip.

[0035] The present application provides a cooling water tank for granulation with a vibration dewatering function, comprising a main tank body 1 and a bracket 7, wherein the main tank body 1 is fixedly mounted on the bracket 7, the main tank body 1 comprises a water receiving tray 6 and a dewatering roller 5, the main tank body 1 is provided with a water inlet 8 and a water outlet 9, the rotating shaft of the dewatering roller 5 is provided with an air vent 11, a water storage tank 10 is provided inside the main tank body 1, an overflow port 3 is provided inside the water storage tank 10, the overflow port 3 is connected to the water outlet 9, the main tank body 1 is further provided with a scraper 4, and both ends of the scraper brush 4 are fixed to the water storage tank 1 0 on both sides, a preliminary water removal operation is performed on the passing strips; when the strips pass through the water removal roller 5, the edges of the water removal roller 5 will cause the plastic strips to vibrate, causing the water droplets attached to the surface of the strips to lose their adhesion and drip onto the water receiving tray 6 below, thereby performing a further water removal operation on the strips; at the same time, a vent 11 is provided on the water removal roller 5, which can blow drying gas toward the direction of the plastic strips, further enhancing the water removal effect, and the water receiving tray 6 is connected to the water removal roller 5, and the cooling water that falls after passing through the water removal roller 5 will flow back into the water storage tank 10, which is beneficial to maintaining a good production site environment.

In addition to the above embodiments, the present invention may also have other implementation methods.
