Conveying device for the production of plastic granules

Abstract

This utility model relates to a conveying device for producing plastic granules, comprising a base plate, a storage frame, a conveying component, and a refrigeration mechanism. The storage frame is installed on top of the base plate and is used for storing plastic granules. Hot plastic granules are poured into the storage frame. The refrigeration unit is powered on, with the cooling surface of the refrigeration unit located inside the insulation frame, cooling the area inside the insulation frame. A high-powered fan is activated, drawing air into the intake pipe and into the frame. Because two guide plates are provided inside the frame, the frame forms a serpentine path, extending the air movement path and improving air cooling. The cooled air enters the storage frame through the exhaust pipe, initially cooling the hot plastic granules in the storage frame. The arc-shaped plate at the bottom of the insulation frame can transfer the low temperature to the conveying pipe. The control valve is opened to allow the initially cooled plastic granules to enter the conveying pipe. The drive unit rotates the spiral conveyor paddle, providing a secondary cooling effect while conveying the plastic granules.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a conveying device for producing plastic granules, comprising:

[0024] The base plate 1, storage frame 2, conveyor 3 and refrigeration mechanism 4 are installed on the top of the base plate 1 for storing plastic granules. The bottom of the storage frame 2 is connected to the conveyor 3 through a control valve. The conveyor 3 is used to transport the plastic granules. The refrigeration mechanism 4 is used to refrigerate the conveyor 3 and the storage frame 2.

[0025] The refrigeration mechanism 4 includes an insulated box 41, a refrigeration plate group 42, and a cold air conveying component 43. The insulated box 41 is installed on the top of the conveying component 3, the refrigeration plate group 42 is fixed on the top of the insulated box 41, and the refrigeration surface is located inside the insulated box 41. The cold air conveying component 43 connects the insulated box 41 and the storage frame 2 to deliver cold air to the storage frame 2 and cool down the plastic particles.

[0026] Specifically, the four rods at the bottom of the storage frame 2 are fixed on the base plate 1, and the control valve passes through the bottom of the base plate 1 and is connected to the conveying pipe 31. A refrigeration mechanism 4 is installed at the top of the conveying pipe 31, which can cool the plastic particles conveyed in the conveying pipe 31 and at the same time deliver cold air to the storage frame 2 to cool the plastic particles in the storage frame 2, thus realizing dual-zone synchronous cooling.

[0027] The cold air delivery component 43 includes a frame 431, an air inlet pipe 432, an exhaust pipe 433, and an air intake fan 434. The frame 431 is fixed inside the insulation box 41, and the top opening of the frame 431 is in contact with the cooling surface of the cooling chip assembly 42. The air inlet pipe 432 is connected to one side of the frame 431, and the air intake fan 434 is provided at the air inlet of the air inlet pipe 432. The exhaust pipe 433 is provided at the other end of the frame 431.

[0028] Furthermore, the intake fan 434 draws air into the frame 431, and after it comes into contact with the cooling surface of the cooling fin assembly 42 and is cooled, it is output through the exhaust pipe 433, thus achieving the purpose of orderly delivery of cold air, allowing the air to be fully cooled before being output, and improving the cooling effect of the air.

[0029] The exhaust pipe 433 has its air outlet located inside the storage frame 2. Two guide plates 5 are fixedly installed inside the frame 431 to form a serpentine channel inside the frame 431, which is used to extend the path of the air entering the frame 431 in order to achieve air cooling.

[0030] It is worth noting that the structure of the guide plate 5 forming a serpentine channel inside the frame 431 extends the contact time and path of the air with the cooling surface of the cooling plate group 42 inside the frame 431, thereby allowing the air to absorb the cold energy more fully and further improving the cooling efficiency of the air. The frame 431 occupies half of the cooling plate group 42 to ensure that the plastic particles are at a suitable temperature during storage.

[0031] The cooling chip assembly 42 is a semiconductor cooling chip assembly 42, and a heat sink 6 is fixedly installed on the heating surface. The air intake of the air intake fan 434 is equipped with a filter screen.

[0032] It should be noted that by using the semiconductor cooling chip assembly 42 in conjunction with the heat sink 6 and the filter screen installed at the intake fan 434, the semiconductor cooling chip assembly 42 achieves efficient cooling, the heat sink 6 dissipates the heat it generates in a timely manner to ensure stable operation, and the filter screen filters impurities in the air, thereby achieving the purpose of ensuring stable and efficient operation of the cooling mechanism 4, improving the service life of the cooling mechanism 4 and the cooling effect.

[0033] The conveying component 3 includes a conveying pipe 31, a screw conveyor 32, a driver 33, and a discharge pipe 34. The conveying pipe 31 is connected to the control valve at the bottom of the storage frame 2. The screw conveyor 32 is rotatably installed inside the conveying pipe 31. The surface of the conveying pipe 31 is provided with a discharge pipe 34, and a driver 33 for rotating the screw conveyor 32 is provided on one side.

[0034] The conveying structure consists of a spiral conveyor 32 rotating inside the conveying pipe 31, a driver 33 adjusting the rotation of the spiral conveyor 32, and a discharge pipe 34. The driver 33 drives the spiral conveyor 32 to rotate, conveying plastic granules from one end of the conveying pipe 31 to the other end and outputting them through the discharge pipe 34, thus achieving a continuous and stable effect for plastic granules.

[0035] An arc-shaped plate 7 is fixedly installed at the bottom of the heat preservation box 41. The arc-shaped plate 7 is set as a heat-conducting plate and is embedded in the top of the conveying pipe 31.

[0036] Specifically, by installing a heat-conducting arc plate 7 at the bottom of the insulation box 41 and embedding it in the top of the conveying pipe 31, the cold energy in the insulation box 41 can be transferred to the conveying pipe 31 more quickly and effectively, thereby enhancing the cooling effect on the plastic particles in the conveying pipe 31 and improving the cooling efficiency.

[0037] It also includes a stirrer 8 for stirring plastic granules within the storage container 2;

[0038] It is worth noting that by setting a stirrer 8 inside the storage frame 2, the stirrer 8 stirs the plastic particles inside the storage frame 2, thereby preventing the plastic particles from accumulating and clumping, allowing the cold air to contact the plastic particles more evenly, and improving the cooling effect inside the storage frame 2.

[0039] In this embodiment, the stirrer 8 includes a motor, a stirring rod, and a stirring paddle. The motor drives the stirring rod to rotate, so that the stirring paddles on both sides of the stirring rod can stir the plastic particles in the storage frame 2.

[0040] The exhaust pipe 433 is also made of heat-insulating material, and the heating surface of the cooling plate 42 is fixedly installed with a heat sink 6. A fan is provided on one side of the heat sink 6 to blow air onto the heat sink 6.

[0041] The cooling chip assembly 42, intake fan 434, cooling fan, control valve, stirrer 8 and driver 33 involved in this application are all implemented using existing mature technologies and are connected to an external PLC controller and power supply. This is a conventional technical means in this field, so their specific circuit connections, control logic and working process will not be described in detail.

[0042] The storage frame 2 of this device has an opening at the top. Hot plastic granules are poured into the storage frame 2. The cooling chip assembly 42 is powered on, and the cooling surface of the cooling chip assembly 42 is located inside the insulation frame to cool the inside of the insulation frame. The fan is started to draw air into the intake pipe 432 and into the frame 431. Since there are two guide plates 5 inside the frame 431, the frame 431 forms a serpentine path, which extends the air movement path and cools the air better. The cooled air enters the storage frame 2 through the exhaust pipe 433 to initially cool the hot plastic granules in the storage frame 2. The arc plate 7 at the bottom of the insulation frame can transfer the low temperature to the conveying pipe 31. The control valve is opened to let the initially cooled plastic granules into the conveying pipe 31. The driver 33 drives the spiral conveying paddle 32 to rotate, providing a secondary cooling effect while conveying the plastic granules.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
