Description

Technical Field

[0001] This utility model relates to the technical field of ABS plastic granule production equipment, and in particular to an integrated device for cooling and sieving ABS plastic granules. Background Technology

[0002] In the field of plastics processing, the integrated cooling and screening device for ABS plastic granules is a crucial piece of equipment. Its main function is to simultaneously perform two important operations on ABS plastic granules after the extrusion molding process: cooling and screening. This ensures that the plastic granules reach the appropriate temperature and particle size specifications to meet the needs of subsequent production and processing, significantly improving production efficiency and optimizing product quality. This device occupies a vital position in the entire plastics industry chain, directly affecting the production efficiency and final quality of plastic products.

[0003] Early ABS plastic granule cooling and screening devices had relatively simple structures, consisting of a simple air-cooled device combined with a common vibrating screen. The air-cooled device relied on natural convection or a small fan for cooling, while the vibrating screen used a simple motor to drive vibration for screening. However, air cooling was inefficient, resulting in long production cycles and an inability to precisely control the granule cooling temperature. The screening accuracy of the vibrating screen was also limited, easily leading to missed screenings or screen blockages. Existing devices employ more complex and efficient structures, incorporating circulating water cooling systems, forced air cooling systems, and cooling ducts with uniform flow structures for cooling. However, existing integrated cooling and screening devices still have significant shortcomings in cooling efficiency. Despite using various cooling devices to cool ABS plastic granules, excessive energy consumption remains a prominent issue. The prolonged high-load operation of the water pump consumes a large amount of electricity. Furthermore, to maintain a stable cooling water temperature, refrigeration equipment is required, further increasing energy consumption. Simultaneously, the prolonged high-load operation of the cooling equipment not only exacerbates equipment wear and significantly increases maintenance costs, but also keeps production costs high, severely impacting the company's economic benefits and market competitiveness. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated cooling and screening device for ABS plastic granules, which aims to improve the problem of high energy consumption in the existing technology, which leads to high production costs for enterprises.

[0007] The screening and filtering mechanism includes an external pipe, which is fixedly connected to the left side of the outer wall of the screening box. The right side of the outer wall of the external pipe passes through the screening box and is connected to a U-shaped pipe. The bottom of the U-shaped pipe is connected to multiple nozzles. Multiple buffer springs are fixedly connected to the top of the screening box. A heat-absorbing plate is fixedly connected to the top of each of the multiple buffer springs. A vibrator is fixedly connected to the right side of the heat-absorbing plate. Connecting plates are fixedly connected to the front and rear sides of the bottom of the heat-absorbing plate. The bottom ends of two connecting plates pass through the screening box and are fixedly connected to a filter screen.

[0008] As a further description of the above technical solution:

[0009] A bent copper tube is fixedly connected to the inner wall of the heat absorption plate. Both the front and rear sides of the bent copper tube are connected to a connection port, and a conical block is fixedly connected to the outer wall of the connection port.

[0010] As a further description of the above technical solution:

[0011] The top of the heat absorption plate is provided with multiple limiting posts, the outer wall of which penetrates the heat absorption plate and is fixedly connected to the top of the screening box.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a DC motor is started to drive the rotating column to rotate at high speed, and the rotating cylinder will then perform circumferential motion. During the rotation of the rotating cylinder, the inclined pusher pushes the ABS plastic particles to the bottom. Cold air enters the cooling cylinder through the air inlet and is guided by the guide plate. The honeycomb cylinder disperses the cold air, allowing it to circulate around the rotating cylinder and exchange heat with the plastic particles to achieve cooling. The conical discharge block guides the cooled particles to converge towards the center, and the spiral pusher pushes the particles to the screening box to ensure effective cooling of the plastic particles.

[0022] 2. In this utility model, air is introduced through an external pipe and a U-shaped pipe, and evenly distributed to the nozzle. The high-speed airflow disperses the plastic particles, preventing agglomeration. The buffer spring supports the heat absorption plate, reducing the impact on the top of the screening box when the vibrator starts and keeping the heat absorption plate stable. The connecting plate connects the heat absorption plate and the filter screen. When vibrating, the filter screen is driven to screen the particles. Under the action of vibration and airflow, particles of qualified size pass through the filter screen, completing the cooling and screening process, ensuring stable and efficient operation of the device.

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an integrated cooling and sieving device for ABS plastic granules, comprising a screening box 1, a support plate 3 fixedly connected to the top right side of the screening box 1, and a cooling cylinder 4 fixedly connected to the left side of the support plate 3. External cold air enters through multiple air inlets 12 on the outer wall of the cooling cylinder 4, and is guided by a guide plate 13 to flow in a specific direction, avoiding airflow turbulence and allowing the cold air to enter the interior of the cooling cylinder 4. A U-shaped bracket 5 is fixedly connected to the top of the cooling cylinder 4, and a DC motor 6 is fixedly connected to the top of the U-shaped bracket 5. The output end of the DC motor 6 passes through the U-shaped bracket 5 and is fixedly connected to a rotating column 7. A rotating cylinder 8 is fixedly connected to the outer wall of the rotating column 7. When the DC motor 6 starts running, it drives the rotating column 7 to rotate at high speed, causing the rotating cylinder 8 to rotate around its own axis. Multiple inclined push plates 9 are fixedly connected to the inner wall of the rotating cylinder 8. During the rotation of the rotating cylinder 8, the inclined push plates 9 push the incoming air... The ABS plastic particles inside the rotating cylinder 8 are pushed by a force. A conical discharge block 10 is fixedly connected to the bottom end of the rotating cylinder 8. A spiral pusher plate 11 is fixedly connected to the inner wall of the conical discharge block 10. The spiral pusher plate 11 fixed to the inner wall of the conical discharge block 10 rotates with the rotation of the rotating column 7, pushing the plastic particles gathered at the center downward along the spiral trajectory, so that the plastic particles are discharged orderly from the discharge port of the conical discharge block 10. The outer wall of the cooling cylinder 4 is provided with multiple air inlets 12. A guide plate 13 is fixedly connected to the inner wall of the air inlet 12. A honeycomb cylinder 14 is fixedly connected to the inner wall of the cooling cylinder 4. The honeycomb cylinder 14 further evenly distributes and disperses the cold air, so that the cold air is evenly surrounding the rotating cylinder 8 and exchanges heat with the plastic particles inside the rotating cylinder 8 to achieve cooling of the plastic particles. The inner wall of the screening box 1 is provided with a screening and filtering mechanism 2, which is used to filter the cooled plastic particles.

[0032] Specifically, the DC motor 6 starts running, driving the rotating column 7 to rotate at high speed. The rotating cylinder 8 then rotates around its own axis. During the rotation of the rotating cylinder 8, the inclined pusher 9 applies a pushing force to the ABS plastic particles entering the rotating cylinder 8, moving them towards the bottom of the rotating cylinder 8, thus achieving orderly conveying and tumbling of the particles within the rotating cylinder 8. At the same time, outside cold air enters through multiple air inlets 12 on the outer wall of the cooling cylinder 4. The guide plate 13 guides the cold air to flow in a specific direction, avoiding airflow turbulence and allowing the cold air to enter the interior of the cooling cylinder 4. The honeycomb cylinder 14 further evens out and disperses the cold air. The system ensures that cold air is evenly distributed around the rotating cylinder 8, exchanging heat with the plastic particles inside the cylinder 8 to cool them. At the bottom of the rotating cylinder 8, a fixedly connected conical discharge block 10 guides the cooled plastic particles to converge towards the center. The spiral pusher plate 11 fixed to the inner wall of the conical discharge block 10 rotates with the rotation of the rotating column 7, pushing the plastic particles that have converged to the center downwards along the spiral trajectory. This allows the plastic particles to be discharged orderly from the discharge port of the conical discharge block 10 and fall into the screening box 1 below, thus enabling the plastic particles to be cooled better without using excessive energy for cooling.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The screening and filtering mechanism 2 includes an external pipe 201, which is fixedly connected to the left side of the outer wall of the screening box 1. The right side of the outer wall of the external pipe 201 passes through the screening box 1 and is connected to a U-shaped pipe 202. The bottom of the U-shaped pipe 202 is connected to multiple nozzles 203. External air enters through the external pipe 201 and is evenly distributed to the multiple nozzles 203 through the U-shaped pipe 202, spraying compressed air into the plastic granule pile above the screen in the form of a high-speed airflow. Multiple buffer springs 206 are fixedly connected to the top of the screening box 1. The buffer springs 206 mainly serve to buffer and support the heat absorption plate 204. Multiple buffer springs 206 are fixedly connected to the top of heat-absorbing plates 204. In addition to being vibrated by the vibrator 205, the heat-absorbing plates 204 also absorb heat to further reduce the temperature of the plastic particles. The vibrator 205 is fixedly connected to the right side of the heat-absorbing plate 204. Connecting plates 208 are fixedly connected to the front and rear sides of the bottom of the heat-absorbing plate 204. The connecting plates 208 firmly connect the heat-absorbing plate 204 to the filter screen 207. The bottom ends of the two connecting plates 208 penetrate the screening box 1 and are fixedly connected to the filter screen 207. During the vibration process, the filter screen 207 screens the plastic particles falling on it.

[0034] Specifically, external air enters through external pipe 201 and is evenly distributed to multiple nozzles 203 through U-shaped pipe 202. Compressed air is then sprayed at high speed onto the plastic granule pile above the screen. The impact force of the airflow disperses the aggregated granules, preventing clumping, and simultaneously assists the movement of the granules on the screen, improving screening efficiency. This is particularly effective for plastic granules that tend to stick together. The buffer spring 206 primarily serves to buffer and support the heat-absorbing plate 204. When the vibrator 205 starts, it generates high-frequency vibration. The vibrator 205 is fixed to the right side of the heat-absorbing plate 204, and its vibration is transmitted to the heat-absorbing plate 204. The buffer spring 206 absorbs the vibration energy to a certain extent, preventing damage to the top of the screening box 1. To prevent excessive impact and ensure the stability of the heat-absorbing plate 204 during vibration, the heat-absorbing plate 204, in addition to being vibrated by the vibrator 205, also absorbs heat, further reducing the temperature of the plastic particles. The connecting plate 208 firmly connects the heat-absorbing plate 204 to the filter screen 207. When the heat-absorbing plate 204 vibrates under the action of the vibrator 205, the connecting plate 208 drives the filter screen 207 to vibrate together. During the vibration, the filter screen 207 screens the plastic particles falling on it. Under the combined action of vibration and airflow, plastic particles of different sizes pass through the filter screen 207 and fall down, completing the entire cooling and screening process, enabling the entire device to operate stably and efficiently.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A bent copper tube 15 is fixedly connected to the inner wall of the heat absorber plate 204. The bent copper tube 15 increases the contact area with the heat absorber plate 204. Both the front and rear sides of the bent copper tube 15 are connected to connection ports 16, which can establish a channel between the bent copper tube 15 and the external cooling medium circulation system. A conical block 24 is fixedly connected to the outer wall of the connection port 16, which can better connect with the external pipe. Multiple limiting posts 17 are provided on the top of the heat absorber plate 204. The outer wall of the limiting post 17 penetrates the heat absorber plate 204 and is fixedly connected to the top of the screening box 1. The limiting post 17 can accurately position and stably support the heat absorber plate 204. A column 18 is fixedly connected to the front end of the top of the screening box 1. The column 18 can be positioned at a suitable height and angle during the operation of the device, making it easy for the operator to observe clearly. A warning light 19 is fixedly connected to the top of the column 18, which can remind the operator to pay attention and prompt the operator to take appropriate measures quickly.

[0036] Specifically, the bending of the copper tube 15 increases the contact area with the heat absorber plate 204, enabling more efficient absorption of the heat transferred by the heat absorber plate 204. The connection port 16 provides a channel for the bent copper tube 15 to connect with the external cooling medium circulation system. The conical block 24 facilitates better connection with external pipes. The limiting column 17 provides precise positioning and stable support for the heat absorber plate 204. The column 18 ensures the device is at a suitable height and viewing angle during operation, allowing for clear observation by operators. The warning light 19 alerts operators, prompting them to take appropriate measures to prevent accidents from occurring or escalating, ensuring the safe and stable operation of the device, and also ensuring that the continuity of production and product quality are not seriously affected.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A discharge plate 20 is fixedly connected to the bottom right side of the inner wall of the screening box 1. The discharge plate 20 provides a smooth discharge path for qualified ABS plastic particles after screening. Conical strips 21 are fixedly connected to the front and rear sides of the bottom of the screening box 1. The conical strips 21 facilitate better force transmission between the screening box 1 and the ground. An observation window 22 is provided at the front of the screening box 1. The observation window 22 provides operators with a way to directly observe the working conditions inside the screening box 1. An outer frame 23 is fixedly connected to the outer wall of the observation window 22. The outer frame 23 can enhance the structural strength of the observation window 22. The upper and lower sides of the outer wall of the conical block 24 are provided with recesses 25. The recesses 25 can better guide the engagement of the external pipe with the conical block 24. Multiple heat-conducting protrusions 26 are fixedly connected to the bottom of the inner wall of the heat-absorbing plate 204. The heat-conducting protrusions 26 can increase the contact points and contact area between the heat-absorbing plate 204 and the particles.

[0038] Specifically, the discharge plate 20 provides a smooth discharge path for qualified ABS plastic granules after screening; the conical strip 21 facilitates better force transmission between the screening box 1 and the ground; the observation window 22 provides operators with a way to directly observe the internal working conditions of the screening box 1; the outer frame 23 enhances the structural strength of the observation window 22, preventing it from breaking due to external impacts, and effectively seals the gap between the observation window 22 and the screening box 1, preventing dust and impurities from entering the screening box 1; the notch 25 better guides the engagement of the external pipes with the conical block 24; and the heat-conducting protrusion 26 increases the contact points and contact area between the heat-absorbing plate 204 and the granules.

[0039] Working principle: First, the DC motor 6 starts running, driving the rotating column 7 to rotate at high speed. Simultaneously, the rotating cylinder 8 also rotates around its axis. During this process, the inclined pusher plate 9 applies a pushing force to the ABS plastic granules entering the rotating cylinder 8, causing them to move towards the bottom of the cylinder 8, thus achieving orderly conveying and tumbling of the granules within the cylinder. At the same time, external cold air flows in through multiple air inlets 12 on the outer wall of the cooling cylinder 4. Guided by the guide plate 13, the cold air flows in a specific direction, effectively avoiding airflow turbulence and ensuring smooth entry of the cold air into the cooling cylinder 4. Furthermore, the honeycomb cylinder 14 performs uniform flow and dispersion treatment on the cold air. This allows the material to evenly surround the rotating cylinder 8 and exchange heat with the plastic particles inside the cylinder, thereby achieving effective cooling of the plastic particles. At the bottom of the rotating cylinder 8, the fixedly connected conical discharge block 10 plays a guiding role, causing the cooled plastic particles to converge towards the center. The spiral pusher plate 11 fixed on the inner wall of the conical discharge block 10 rotates synchronously with the rotation of the rotating column 7, pushing the plastic particles that have converged to the center downward along the spiral trajectory, ensuring that the plastic particles are discharged in an orderly manner from the discharge port of the conical discharge block 10 and finally fall into the screening box 1 below. This process not only optimizes the cooling effect of the plastic particles, but also avoids excessive energy consumption.

[0040] Furthermore, through the screening and filtering mechanism 2, air is introduced from the outside via the external pipe 201, and then evenly distributed to multiple nozzles 203 through the U-shaped pipe 202. Compressed air is sprayed into the plastic granule pile above the screen in the form of a high-speed airflow. Its impact helps to disperse the aggregated particles, prevent particle agglomeration, and assist the movement of particles on the screen, thereby improving screening efficiency. This effect is particularly significant for easily sticky plastic granules. The buffer spring 206 mainly plays the role of buffering and supporting the heat absorption plate 204. After the vibrator 205 is started, it generates high-frequency vibration. The vibrator 205, fixed to the right side of the heat absorption plate 204, transmits the vibration to the heat absorption plate 204. The buffer spring 206 can absorb the vibration energy to a certain extent to avoid vibration. The vibration causes excessive impact on the top of the screening box 1, while ensuring the stability of the heat absorption plate 204 during the vibration process. In addition to bearing the vibration of the vibrator 205, the heat absorption plate 204 also has the function of absorbing heat, further reducing the temperature of the plastic particles. The connecting plate 208 firmly connects the heat absorption plate 204 to the filter screen 207. When the heat absorption plate 204 vibrates under the action of the vibrator 205, the connecting plate 208 drives the filter screen 207 to vibrate together. During the vibration process, the filter screen 207 screens the plastic particles falling on it. Under the combined action of vibration and airflow, the qualified particles pass through the filter screen 207 and fall down, completing the entire cooling and screening process, ensuring the stable and efficient operation of the entire device.

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.
