Description

Technical Field

[0001] This utility model belongs to the field of plastic granule preparation technology, and in particular relates to a rapid cooling device for plastic granule preparation. Background Technology

[0002] Plastic pellet preparation is the process of transforming various plastic raw materials into granular materials with certain shapes, sizes and properties through a series of physical or chemical processing processes. The plastic pellet processing flow, the granulation process is the production process of producing granular plastic by metering, mixing, plasticizing and pelletizing high polymer resin with various additives and auxiliaries.

[0003] In the process of preparing plastic granules, the cooling process is crucial. From the perspective of processing technology, after plastic is heated, melted and shaped by equipment such as extruders, it is in a high-temperature state. If it is not cooled in time, the plastic granules may deform due to their own gravity and fail to form a regular granule shape.

[0004] Currently, existing plastic pellet cooling devices typically place the plastic pellets to be cooled on a conveyor belt, and the movement of the conveyor belt moves the plastic pellets. At the same time, the cooling fan at the top cools the plastic pellets. However, this cooling method often results in poor cooling effect on the side of the plastic pellets facing away from the fan, resulting in insufficient cooling of the plastic pellets, which will affect the production and preparation of plastic pellets.

[0005] To address the aforementioned problems, this application proposes a rapid cooling device for preparing plastic granules. Utility Model Content

[0006] The purpose of this invention is to provide a rapid cooling device for preparing plastic granules, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a rapid cooling device for preparing plastic granules, comprising a housing, a conveyor belt rotatably connected to the inner wall of the housing, two cooling racks arranged inside the housing, a rotary motor, a cooling module, a controller, and an exhaust fan respectively arranged on the front of the housing, the output end of the rotary motor being fixedly connected to the transmission end of the conveyor belt, exhaust plates being fixedly connected to the upper and lower surfaces of the housing, two connecting pipes being fixedly connected to the outer surface of the input end of the exhaust fan, the ends of the two connecting pipes away from the controller being fixedly connected to the opposite sides of the two exhaust plates, and a T-junction being fixedly connected to the output end of the cooling module, the end of the T-junction near the housing penetrating the housing and fixedly connected to the outer surface of the cooling rack.

[0009] Furthermore, two sets of support columns are fixedly connected to the bottom surface of the shell, and a support ring is fixedly connected to the bottom end of each support column.

[0010] Furthermore, a connecting plate is fixedly connected to the back of the controller, and the back of the connecting plate is fixedly connected to the front of the housing.

[0011] Furthermore, a connecting seat is fixedly connected to the back of the exhaust fan, and the back of the connecting seat is fixedly connected to the front of the housing.

[0012] Furthermore, a fixing plate is fixedly connected to the bottom surface of the refrigeration module, and the back side of the fixing plate is fixedly connected to the front side of the housing.

[0013] Furthermore, a support base is fixedly connected to the bottom surface of the rotary motor, and the back side of the support base is fixedly connected to the front side of the housing.

[0014] Furthermore, each of the cooling racks has a reinforcing plate fixedly connected to its outer surface, and the two reinforcing plates are fixedly connected to the inner bottom wall and the inner top wall of the shell respectively on their opposite sides.

[0015] This utility model has the following beneficial effects:

[0016] This utility model is equipped with a controller that can control the opening and closing of the equipment. At the same time, the rotation of the rotary motor can drive the conveyor belt to rotate on the shell. The rotation of the conveyor belt can carry the plastic granules. Simultaneously, the opening of the exhaust fan can transfer the exhaust force to the connecting pipe and the exhaust plate. Through the exhaust plate, the heat of the plastic granules on the conveyor belt can be drawn to the outside of the shell, thereby enabling the plastic granules to undergo preliminary cooling.

[0017] This utility model is equipped with a refrigeration module, which can cool the air and transfer it to the refrigeration rack through a three-way pipe. At the same time, the refrigeration rack can cool the inside of the shell, and the conveyor belt can move the pre-cooled plastic particles into the inside of the shell, thereby enabling the plastic particles to be cooled down quickly and comprehensively.

[0018] In summary, the rotary motor drives the conveyor belt to rotate within the housing, allowing the plastic granules to be transported within the housing. The exhaust fan activates the connecting pipes and exhaust plates, drawing heat from the plastic granules to the outside of the housing. Then, the cooling module, in conjunction with the three-way pipe, enables the cooling rack to cool the interior of the housing. The conveyor belt then transfers the partially cooled plastic granules to the cooling space, allowing for rapid and comprehensive cooling of the plastic granules.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] Please see Figure 1-4As shown, this utility model is a rapid cooling device for preparing plastic granules, including a shell 1. A conveyor belt 8 is rotatably connected to the inner wall of the shell 1. Two cooling racks 7 are arranged inside the shell 1. A rotary motor 5, a cooling module 4, a controller 2, and an exhaust fan 12 are respectively arranged on the front of the shell 1. The output end of the rotary motor 5 is fixedly connected to the transmission end of the conveyor belt 8. Exhaust plates 10 are fixedly connected to the upper and bottom surfaces of the shell 1. Two connecting pipes 13 are fixedly connected to the outer surface of the input end of the exhaust fan 12. The ends of the two connecting pipes 13 away from the controller 2 are fixedly connected to the opposite sides of the two exhaust plates 10. A three-way pipe 15 is fixedly connected to the output end of the cooling module 4. The end of the three-way pipe 15 near the shell 1 passes through the shell 1 and is fixedly connected to the outer surface of the cooling rack 7. In this embodiment, the conveyor belt 8 has through holes to allow air to flow. At the same time, the through holes are smaller than the plastic granules, which can convey the plastic granules.

[0030] Two sets of support columns 9 are fixedly connected to the bottom surface of the shell 1. Each support column 9 has a support ring 6 fixedly connected to its bottom end. In this embodiment, the support column 9 can fix the support ring 6 to the shell 1, thereby enabling the shell 1 to be placed stably.

[0031] The back of the controller 2 is fixedly connected to the connecting plate 3, and the back of the connecting plate 3 is fixedly connected to the front of the housing 1. In this embodiment, the controller 2 can be fixed to the housing 1 for use through the connecting plate 3. The controller 2 refers to the master control device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0032] The exhaust fan 12 is fixedly connected to the back of the housing 1. The back of the connecting seat 11 is fixedly connected to the front of the housing 1. In this embodiment, the exhaust fan 12 can be fixed to the housing 1 through the connecting seat 11. The exhaust fan 12 is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is mainly composed of impeller, housing, air inlet and air outlet.

[0033] The bottom surface of the refrigeration module 4 is fixedly connected to a fixing plate 14, and the back side of the fixing plate 14 is fixedly connected to the front side of the housing 1. In this embodiment, the refrigeration module 4 can be fixed on the housing 1 by the fixing plate 14. The refrigeration module 4 consists of a compressor, a condenser, an expansion valve, an evaporator, and a control system.

[0034] The bottom surface of the rotary motor 5 is fixedly connected to a support base 16, and the back side of the support base 16 is fixedly connected to the front side of the housing 1. In this embodiment, the rotary motor 5 can be fixed on the housing 1 through the support base 16, so that the rotary motor 5 can be used stably.

[0035] Each refrigeration rack 7 has a reinforcing plate 17 fixedly connected to its outer surface. The two reinforcing plates 17 are respectively fixedly connected to the inner bottom wall and the inner top wall of the housing 1 on opposite sides. In this embodiment, the refrigeration rack 7 can be fixed inside the housing 1 by the reinforcing plates 17, thereby making the refrigeration rack 7 sturdy when in use.

[0036] Understandably, firstly, the rotating motor 5, in conjunction with the conveyor belt 8, enables the plastic granules to move within the housing 1. Secondly, the exhaust fan 12, in conjunction with the connecting pipe 13 and the exhaust plate 10, can initially extract the heat from the plastic granules outside the housing 1. Simultaneously, the cooling module 4, in conjunction with the three-way pipe 15 and the cooling rack 7, can cool the interior of the housing 1, thereby enabling the initially cooled plastic granules to be rapidly and comprehensively cooled, further facilitating the stable production and preparation of the plastic granules.

[0037] A specific application of this embodiment is as follows: In use, firstly, connect the rotary motor 5, cooling module 4, exhaust fan 12, and controller 2 to the power supply. Simultaneously, connect the rotary motor 5, cooling module 4, and exhaust fan 12 to the controller 2 via wires. Place the housing 1 in a suitable position, and support the housing 1 using the support column 9 and support ring 6. When ready for use, place the plastic granules on the conveyor belt 8, and activate the rotary motor 5 via the controller 2. The rotation of the rotary motor 5 drives the conveyor belt 8 to rotate on the housing 1, and the rotation of the conveyor belt 8 transports the plastic granules. Then, activate the exhaust fan 12 and cooling module 4 via the controller 2. The system draws air from the connecting pipe 13 and the exhaust plate 10, drawing heat from the plastic granules as they pass below. This heat is then transferred to the exhaust fan 12, which in turn transfers the heat to the outside of the housing 1, thus initially cooling the plastic granules. Simultaneously, the refrigeration module 4 is activated to cool the air, which is then transferred to the three-way pipe 15 and the refrigeration rack 7, cooling the inside of the housing 1. When the conveyor belt 8 carries the initially cooled plastic granules into the housing 1, the cold air rapidly and comprehensively cools the plastic granules, further enabling the stable and rapid production of plastic granules.
