Description

Technical Field

[0001] This utility model relates to the field of polypropylene (PP) granule processing technology, and in particular to a cooling device for processing polypropylene (PP) granules. Background Technology

[0002] Polypropylene (PP) granules are thermoplastic resin granules produced from propylene monomers through an addition polymerization reaction. They are characterized by their light weight, high melting point, strong chemical stability, and balanced mechanical properties. The granules are mostly cylindrical or spherical, typically 2-5 mm in diameter, and are primarily white or transparent in color. Colored granules can also be produced by adding masterbatches as needed. During the processing of PP granules, cooling devices are used to cool the high-temperature PP granules after extrusion and pelletizing to room temperature, preventing granule sticking and deformation. Some devices also integrate a water circulation filtration system to reduce the impact of impurities in the water on the surface quality of the granules. Furthermore, stainless steel (such as 304 stainless steel) is used for contact parts to prevent rust contamination.

[0003] Existing technologies, such as the utility model patent with publication number CN218171002U, disclose a cooling device for processing polypropylene (PP) granules. This patent employs an extrusion box, a first motor, a second motor, a cutting blade, an extrusion orifice, and a filter screen. A support frame is fixedly connected to the upper end of the extrusion box, and a rack is connected through the interior of the support frame. The first motor is installed and connected to the lower middle part of the extrusion box, and a protective box is fixedly connected to the lower middle part of the extrusion box. The second motor is installed and connected to the front end face of the support frame, and a gear is fixedly connected to the output end of the second motor. The cutting blade is fixedly connected to the left and right ends of the mounting frame, and the mounting frame is rotatably connected to the lower outer surface of the protective box through the output end of the first motor. The extrusion orifice is opened on the lower end face of the extrusion box. This invention solves the problems of existing equipment being inconvenient for uniformly granulating polypropylene (PP) materials, as well as for uniform and sufficient cooling and stable conveying.

[0004] Existing PP particle processing and cooling devices, such as those described above, require workers to disassemble the filter screen that collects the PP particles after the particles have fallen into the water tank and cooled. During disassembly, the cooled particles collected in the filter screen are removed. After disassembly, the filter screen needs to be reinstalled into the equipment. This causes the efficiency of the equipment in collecting PP particles to be affected by disassembly and reassembly operations, resulting in a limitation on the extraction efficiency of the processed particles. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the filter screen needs to be disassembled and then reinstalled into the equipment, which affects the efficiency of the equipment in collecting PP particles and restricts the extraction efficiency of the processed particles. Therefore, a cooling device for processing polypropylene PP particles is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cooling device for processing polypropylene (PP) granules, comprising a water storage tank, a water inlet connector, and a water outlet connector, wherein the water inlet connector is fixedly connected to the right side surface of the water storage tank, the water outlet connector is fixedly connected to the left side surface of the water storage tank, and a feeding device is provided on the inner wall of the water storage tank.

[0007] The feeding device includes a connecting sleeve. The water storage tank has mounting cavities on both the left and right sides. The connecting sleeve is fixedly connected to the inner wall of the mounting cavity. A push plate is rotatably connected to the inner wall of the connecting sleeve. A shield is fixedly connected to the inner wall of the water storage tank. A bracket is fixedly connected to the left side of the water storage tank. A motor is fixedly connected to the inner wall of the bracket. A gear one is fixedly connected to the drive shaft of the motor.

[0008] Preferably, a fixing plate is fixedly connected to the left side of the water storage tank. The surface of the fixing plate has a through hole. The left connecting sleeve is located on the inner wall of the through hole. A protective cover is fixedly connected to the surface of the fixing plate. The protective cover is fitted onto the surface of gear one and gear two. The protective cover is sleeved with the left side of the push plate and with the drive shaft of the motor. By using the cooperation between the protective cover and the fixing plate, gear one and gear two in transmission can be protected, reducing the problem of damage caused by the exposure of gear one and gear two, and improving the stability of gear one and gear two in transmission.

[0009] Preferably, both ends of the push plate are arc-shaped, and the surface of the push plate is provided with drainage holes. The inner wall of the shield is arc-shaped. The push plate is located inside the water tank and is in contact with the arc surface of the shield. Using the push plate in the working state, it can cooperate with the shield to push the cooled particles out of the water tank. When the push plate is rotated to the upward tilted state, the particles on the push plate can be sent out of the water tank along the tilted push plate.

[0010] Preferably, the surface of the water storage tank is provided with an assisting device, which includes a limiting frame. The limiting frame is fixedly connected to the surface of the water storage tank. A magnetic sleeve is fixedly connected to the inner wall of the limiting frame. A protective frame is installed on the upper surface of the water storage tank. A connecting block is fixedly connected to the surface of the protective frame. A metal pin is fixedly connected to the lower surface of the connecting block. The metal pin is inserted into the inner wall of the limiting frame. A guide plate one is fixedly connected to the inner wall of the protective frame. A guide plate two is fixedly connected to the inner wall of the protective frame. The guide plate two abuts against the upper surface of the shielding frame. The protective frame can be used to raise the water storage tank so that when particles fall into the water storage tank, they can shield the splashed water source.

[0011] Preferably, the magnetic sleeve is magnetically connected to the metal pin, and a protruding plate is provided on the front side of the protective frame. The protruding plate of the protective frame is inserted into the inner wall of the water tank. The magnetic sleeve can restrict the position of the metal pin. When the metal pin is in the restricted state, it can cooperate with the connecting block to restrict the position of the protective frame.

[0012] Preferably, the lower surface of the metal pin is chamfered, the first guide plate is triangular, and the second guide plate is triangular. By using the cooperation of the first guide plate and the second guide plate, the particles entering the protective frame can be guided to ensure that the particles fall into the water tank and reduce the probability of the particles falling out of the water tank from the opening.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting up a feeding device, the cooling device used for PP granules can remove the cooled PP granules from the cooling device without disassembling the structure.

Detailed Implementation

[0026] Please see Figures 1-8 This utility model provides a technical solution: a cooling device for processing polypropylene (PP) granules, including a water storage tank 1, a water inlet connector 2 and a water outlet connector. The water inlet connector 2 is fixedly connected to the right side surface of the water storage tank 1, and the water outlet connector is fixedly connected to the left side surface of the water storage tank 1. A feeding device 4 is provided on the inner wall of the water storage tank 1.

[0027] Specifically, the feeding device 4 includes a connecting sleeve 41. The water tank 1 has installation cavities on both the left and right sides. The connecting sleeve 41 is fixedly connected to the inner wall of the installation cavity. The inner wall of the connecting sleeve 41 is rotatably connected to a push plate 42. The inner wall of the water tank 1 is fixedly connected to a shielding frame 43. The left side of the water tank 1 is fixedly connected to a bracket 44. The inner wall of the bracket 44 is fixedly connected to a motor 45. A gear 46 is fixedly connected to the drive shaft of the motor 45. A gear 47 that meshes with the gear 46 is fixedly connected to the left side of the push plate 42.

[0028] Specifically, a fixing plate 48 is fixedly connected to the left side of the water storage tank 1. A through hole is opened on the surface of the fixing plate 48. The left connecting sleeve 41 is located on the inner wall of the through hole. A protective cover 49 is fixedly connected to the surface of the fixing plate 48. The protective cover 49 is sleeved on the surface of gear 1 46 and gear 2 47. The protective cover 49 is sleeved on the left side of the push plate 42 and sleeved on the drive shaft of the motor 45.

[0029] In this embodiment, the protective cover 49 and the fixing plate 48 are used to protect the transmission gear 46 and gear 47, reduce the damage caused by the exposure of gear 46 and gear 47, and improve the stability of gear 46 and gear 47 in transmission.

[0030] Specifically, both ends of the push plate 42 are arc-shaped, and the surface of the push plate 42 is provided with drainage holes. The inner wall of the shielding frame 43 is arc-shaped, and the push plate 42 is located inside the water storage tank 1 on one side and makes contact with the arc surface of the shielding frame 43.

[0031] In this embodiment: the push plate 42 in the working state can be used in conjunction with the shielding frame 43 to push the cooled particles out of the water storage tank 1, and when the push plate 42 is rotated to the upward tilted state, the particles on the push plate 42 can be sent out of the water storage tank 1 along the tilted push plate 42.

[0032] Specifically, the surface of the water tank 1 is provided with an assisting device 5, which includes a limiting frame 51. The limiting frame 51 is fixedly connected to the surface of the water tank 1. A magnetic sleeve 52 is fixedly connected to the inner wall of the limiting frame 51. A protective frame 53 is installed on the upper surface of the water tank 1. A connecting block 54 is fixedly connected to the surface of the protective frame 53. A metal pin 55 is fixedly connected to the lower surface of the connecting block 54. The metal pin 55 is inserted into the inner wall of the limiting frame 51. A guide plate 1 56 is fixedly connected to the inner wall of the protective frame 53. A guide plate 2 57 is fixedly connected to the inner wall of the protective frame 53. The guide plate 2 57 abuts against the upper surface of the shielding frame 43.

[0033] In this embodiment, the protective frame 53 can be used to raise the water storage tank 1, so that when the particles fall into the water storage tank 1, the splashed water source can be blocked.

[0034] Specifically, the magnet sleeve 52 is magnetically connected to the metal pin 55, and a protruding plate is provided on the front side of the protective frame 53. The protruding plate of the protective frame 53 is inserted into the inner wall of the water storage tank 1.

[0035] In this embodiment: the position of the metal pin 55 can be restricted by the magnet sleeve 52. When the metal pin 55 is in the restricted state, it can be used in conjunction with the connecting block 54 to restrict the position of the protective frame 53.

[0036] Specifically, the lower surface of the metal pin 55 is chamfered, the first guide plate 56 is triangular, and the second guide plate 57 is triangular.

[0037] In this embodiment, the particles entering the protective frame 53 can be guided by the cooperation of guide plate 56 and guide plate 57 to ensure that the particles fall into the water tank 1 and reduce the probability of particles falling out of the water tank 1 from the opening.

[0038] Working principle: During processing, the output and input ends of the cooling water circulation system are installed on the water inlet connector 2 and the drain connector 3, respectively. After the installation of the cooling water circulation system is completed, water for cooling PP granules can be injected into the water storage tank 1. After the PP granules are processed and formed, they fall into the water storage tank 1 and are cooled by the water in the water storage tank 1. During the cooling process, the cooling water circulation system works synchronously to keep the water in the water storage tank 1 flowing, thereby ensuring that the temperature of the water in the water storage tank 1 is at a suitable cooling temperature. The cooling water circulation system adopts the existing cooling circulation structure used in PP granule processing, which will not be described in detail here.

[0039] After the PP granules in the same batch have cooled, the switch of motor 45 is turned on. Motor 45 drives gear 1 46, which meshes with gear 2 47. Under the action of gear 1 46, gear 2 47 drives push plate 42 to rotate. During the rotation, push plate 42, in conjunction with shield 43, pushes out the PP granules that have cooled in water tank 1. At the same time, the drain hole on push plate 42 ensures that the water source flows back to water tank 1 during the movement of push plate 42. When push plate 42 rotates to the maximum angle, push plate 42 is tilted. At this time, the PP granules on push plate 42 are discharged from the opening of water tank 1 under the guidance of push plate 42 in the tilted state.

[0040] After the same batch of PP granules is fed, the motor 45, in conjunction with gear 1 46 and gear 2 47, drives the push plate 42 to reset. During the reset process, the push plate 42 comes into contact with the water source. When the push plate 42 is submerged in the water source, the water source is squeezed by the push plate 42 and is flushed and cleaned through the drainage holes on the surface of the push plate 42. By setting the feeding device 4, the cooling device used for PP granules can remove the cooled PP granules from the cooling device without disassembling the structure. This reduces the need to disassemble the cooling device to remove PP granules, thus reducing the problem of the cooling device's efficiency in extracting materials and further improving the working efficiency of the cooling device in extracting materials.

[0041] In addition, before using the cooling device, the assisting device 5 is installed on the water storage tank 1. When installing the assisting device 5, the metal pins 55 are aligned with the limiting frame 51. After all the metal pins 55 are aligned with the limiting frame 51, the protective frame 53 is pushed down. The protective frame 53, together with the connecting block 54, pushes the metal pins 55. The metal pins 55 are inserted into the limiting frame 51 under force. When the metal pins 55 are fully inserted into the limiting frame 51, the magnet sleeve 52 located in the limiting frame 51 attracts the metal pins 55 by magnetic force, thereby restricting the position of the metal pins 55. After the position of the metal pins 55 is restricted, the protective frame 53 is installed above the water storage tank 1. Subsequently, when the water storage tank 1 is running, the protective frame 53 will work with the guide plate 1 56 and the guide plate 2 57 to guide the falling PP particles. By setting the assisting device 5, the cooling device can guide the falling particles during use, reducing the problem of particles falling through the opening of the cooling device and causing particles to pollute the external working environment, and improving the collection effect of the cooling device on PP particles.

[0042] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
