Description

Technical Field

[0001] This utility model relates to a cooling device, and more particularly to a water-cooling device for the production of modified plastic granules. Background Technology

[0002] In the production process of modified plastic granules, the cooling process is a crucial step. Traditional cooling methods mainly include natural cooling, air cooling, and water cooling.

[0003] However, existing cooling devices have some shortcomings. Natural cooling is slow and production efficiency is low. Although traditional water cooling devices have a better cooling effect, they are complex in structure, have low efficiency in the recycling of cooling water, and are difficult to cool plastic granules evenly, which can easily lead to uneven cooling of granules and affect product quality. Utility Model Content

[0004] In order to overcome the shortcomings of existing modified plastic granule cooling devices, such as low cooling efficiency and uneven cooling, the technical problem to be solved is to provide a water-cooling device for the production of modified plastic granules.

[0005] The technical implementation scheme of this utility model is as follows: a water-cooled device for producing modified plastic granules, comprising a cooling box, a support frame, a feeding frame, a discharging bin, a stepped cooling plate, a motor, a crank, a hinge rod, and water-cooling pipes. The support frame is provided at the bottom of the cooling box, and the feeding frame and discharging bin are respectively provided at both ends of the cooling box. The stepped cooling plate is slidably provided at the bottom of the cooling box, and the bottom of the stepped cooling plate is movably connected to one end of the hinge rod. The motor is installed at the bottom of the cooling box, and the output shaft of the motor is connected to the crank. The other end of the hinge rod is movably connected to the crank. Water-cooling pipes are provided inside the stepped cooling plate.

[0006] Preferably, it also includes an air-cooled blower pipe, which is connected to the inside of the cooling box.

[0007] Preferably, it also includes a material distribution wheel, with the material distribution wheel rotatably provided at the lower part of the feeding frame.

[0008] Preferably, it also includes a guide seat, a positioning toothed frame, and a gear. A guide seat is provided at the lower part of the feed frame, and a positioning toothed frame is slidably provided inside the guide seat. A gear is connected to the material distribution wheel, and the gear meshes with the positioning toothed frame.

[0009] Preferably, it also includes a push frame, a pull rope, and a spring. The push frame is connected to the right end of the stepped cooling plate, and the two ends of the pull rope are respectively connected to the push frame and the positioning tooth frame. The guide seat is provided with a guide groove, and the pull rope is located in the guide groove of the guide seat. A spring is connected between the positioning tooth frame and the guide seat.

[0010] Preferably, it also includes a condenser plate and a drain pipe. The condenser plate is disposed on the inner wall of the cooling box, and a V-shaped guide groove is provided at the lower part of the condenser plate. The drain pipe is connected to the condenser plate.

[0011] Preferably, the cooling box, stepped cooling plate, and condenser plate are all inclined, and the drain pipe is connected to the lower end of the condenser plate.

[0012] The beneficial effects of this utility model are: 1. This utility model can break up plastic particles through the reciprocating motion of the stepped cooling plate, increasing the contact area between the particles and the stepped cooling plate. At the same time, combined with the water cooling pipe cooling method, it can quickly remove the heat of the plastic particles and significantly improve the cooling efficiency.

[0013] 2.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] A water-cooling device for producing modified plastic granules, such as Figures 1-3As shown, the system includes a cooling box 1, support frames 2, a feed frame 3, a discharge bin 4, a stepped cooling plate 5, a motor 7, a crank 8, a hinge rod 9, and water-cooling pipes 10. Four support frames 2 are fixedly connected to the bottom of the cooling box 1. These four support frames 2 are arranged symmetrically in pairs, with the two support frames on the left being higher than the two support frames on the right. The discharge bins 4 and feed frames 3 are respectively located at the left and right ends of the cooling box 1. A stepped cooling plate 5 is slidably installed at the bottom of the cooling box 1. Both the cooling plate 5 and the cooling box 1 are inclined with the left side higher than the right side. The bottom of the stepped cooling plate 5 is rotatably connected to the hinge rod 9. The bottom of the cooling box 1 is provided with a through groove for the hinge rod 9 to pass through. The bottom of the cooling box 1 is equipped with a motor 7 and a crank 8. The crank 8 is rotatably connected to the cooling box 1. The output shaft of the motor 7 is connected to the crank 8. The hinge rod 9 is movably connected to the crank 8. The crank 8 adopts an eccentric wheel structure and is connected to the output shaft of the motor 7. Water cooling pipes 10 are horizontally laid inside the stepped cooling plate 5.

[0023] When using this device, the water-cooling pipe 10 is connected to the coolant circulation supply equipment. The motor 7 is started, and its output shaft drives the crank 8 to rotate. The crank 8, through the transmission of the hinge rod 9, converts the rotational motion into a reciprocating motion of the stepped cooling plate 5. Plastic granules are placed into the feed frame 3 and enter the cooling tank 1, landing on the stepped cooling plate 5. The stepped cooling plate 5 reciprocates. When it moves to the left, the raised structure on its surface throws the plastic granules to the upper left, dynamically breaking up any accumulated granules. After the granules are thrown up, the stepped cooling plate 5 moves to the right, and the granules fall onto the stepped cooling plate 5 at a position further to the left than before they were thrown up. During the conveying of plastic granules, the plastic granules come into contact with various parts of the cooling plate 5, significantly increasing the contact area between the plastic granules and the stepped cooling plate 5. The heat emitted by the plastic granules is absorbed by the stepped cooling plate 5 and transferred to the water cooling pipe 10 through heat conduction. The coolant in the water cooling pipe 10 carries the heat out of the cooling box 1. At the same time, the plastic granules gradually move towards the discharge bin 4 under the vibration conveying of the stepped cooling plate 5.

[0024] like Figure 2 As shown, it also includes an air-cooled blower 6, which is connected inside the cooling box 1. The air-cooled blower 6 is connected to an external air cooler. When the air cooler is started, the air-cooled blower 6 blows forced cold air into the particle layer to further enhance convective heat dissipation and prevent local overheating.

[0025] like Figure 5As shown, it also includes a distributing wheel 17. The distributing wheel 17 is rotatably mounted on the lower part of the feeding frame 3, and the distributing wheel 17 is provided with a distributing groove. When the plastic granules enter the cooling box 1 from the feeding frame 3, they pass through the distributing wheel 17. The distributing wheel 17 rotates back and forth, and the plastic granules enter the cooling box 1 in batches through the distributing groove on the distributing wheel 17, realizing intermittent feeding. When the distributing wheel 17 does not rotate, feeding stops.

[0026] like Figure 5 As shown, it also includes a guide seat 12, a positioning toothed frame 14, and a gear 16. The guide seat 12 is provided at the lower part of the feed frame 3, and the positioning toothed frame 14 is slidably provided inside the guide seat 12. The gear 16 is connected to the material distribution wheel 17. The gear 16 meshes with the positioning toothed frame 14. When the material distribution wheel 17 needs to rotate, the positioning toothed frame 14 can be pulled up and down to drive the gear 16 to rotate. The rotation of the gear 16 drives the material distribution wheel 17 to rotate, which makes it easier to rotate the material distribution wheel 17.

[0027] like Figure 4 As shown, it also includes a push frame 11, a pull rope 13 and a spring 15. The push frame 11 is connected to the right end of the stepped cooling plate 5. The two ends of the pull rope 13 are connected to the push frame 11 and the positioning tooth frame 14 respectively. The guide seat 12 is provided with a guide groove. The pull rope 13 is located in the guide groove of the guide seat 12. The positioning tooth frame 14 and the guide seat 12 are connected by a spring 15.

[0028] When the stepped cooling plate 5 moves to the left, the push frame 11 drives the pull rope 13 to move to the left. The pull rope 13 moves in the guide groove of the guide seat 12, pulling the positioning gear frame 14 downward. The positioning gear frame 14 compresses the spring 15. The movement of the positioning gear frame 14 drives the gear 16 to rotate. When the stepped cooling plate 5 moves to the right, the pull rope 13 is released. Under the action of the spring 15, the positioning gear frame 14 moves upward. The movement of the positioning gear frame 14 drives the gear 16 and the material distribution wheel 17 to rotate in opposite directions. In this way, the material distribution wheel 17 rotates and feeds material as the stepped cooling plate 5 moves.

[0029] like Figure 6 As shown, it also includes a condenser plate 18 and a drain pipe 19. The condenser plate 18 is disposed on the inner wall of the cooling box 1. A V-shaped guide groove is provided at the lower part of the condenser plate 18. The condenser plates 18 are all inclined. The drain pipe 19 is connected to the lower end of the condenser plate 18.

[0030] The surface of the condenser plate 18 is coated with a hydrophobic material, which uses the temperature difference effect to condense water vapor in the chamber into droplets. The droplets are collected along the V-shaped guide groove of the condenser plate 18 and discharged into the drain pipe 19 in real time, preventing condensate from accumulating or flowing back and maintaining a dry environment inside the chamber.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
