Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a circulating cooling device for the production of plastic granules. Background Technology

[0002] Plastics are polymers formed by polymerization of monomers through addition or condensation reactions. They have moderate resistance to deformation, falling between fibers and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastics is the polymer compound before it is mixed with various additives. The basic properties of plastics are mainly determined by the nature of the polymer compound, but additives also play an important role. Plastics are important organic synthetic polymer materials with a wide range of applications, but the "white pollution" caused by waste plastics is becoming increasingly serious.

[0003] Engineering plastic granules often need to be cooled during production. However, existing cooling devices for engineering plastic granule production have low cooling efficiency and slow cooling speed, which often consumes a lot of time. Therefore, a circulating cooling device for plastic granule production is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a circulating cooling device for plastic granule production, which solves the problem of low cooling efficiency.

[0005] This utility model also provides a circulating cooling device for producing plastic granules, comprising: a cooling tank, a tank cover installed on the upper side of the cooling tank, a receiving hopper fixedly connected to the upper side of the tank cover, air outlets provided on the tank cover around the receiving hopper, a spiral pipe fixedly connected inside the cooling tank, the spiral pipe having through holes, a discharge pipe fixedly connected to the outer side of the cooling tank, the receiving hopper fixedly connected to the upper end of the spiral pipe and the discharge pipe fixedly connected to the lower end, the outer side of the spiral pipe contacting the inner wall of the cooling tank, a partition fixedly connected to the inner wall of the cooling tank below the spiral pipe, a motor fixedly connected to the bottom of the cooling tank below the partition, several openings provided on the upper side of the partition, fan blades fixedly connected to the output end of the motor, the fan blades being located inside the openings, a wind column fixedly connected to the opening located in the middle of the partition, the wind column being located in the middle of the spiral pipe and having air holes around it.

[0006] According to the aforementioned plastic granule production circulating cooling device, there are five openings evenly distributed on the partition, and there are five motors, each corresponding to one of the openings.

[0007] According to the aforementioned method of producing plastic granules for use in a circulating cooling device, the through holes are numerous and evenly distributed on the spiral pipe.

[0008] According to the aforementioned plastic granule production for a circulating cooling device, there are several air outlets, which are evenly distributed on the barrel lid.

[0009] According to the aforementioned plastic granule production circulating cooling device, a cooling tank located outside the motor is provided with several heat dissipation vents, which are evenly distributed around the cooling tank.

[0010] According to the aforementioned plastic granule production for a circulating cooling device, a dustproof net is fixedly connected inside the heat dissipation port.

[0011] This utility model has the following beneficial effects:

[0012] In this invention, a spiral pipe, fan blades, and air column are provided inside the cooling box. When the plastic particles enter the spiral pipe, the motor and fan blades blow air upwards from the bottom of the cooling box to cool them. The lower the plastic particles move, the better the cooling effect. At the same time, the air column causes the air to radiate outwards from the center to cool the plastic particles. The air cools the plastic particles from different directions, resulting in a better cooling effect.

The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model embodiment provides a circulating cooling device for plastic pellet production, which includes a cooling tank 1. The cooling tank 1 is cylindrical in shape. A tank cover 2 is installed on the upper side of the cooling tank 1. A receiving hopper 3 is fixedly connected to the upper side of the tank cover 2. Air outlets 21 are provided on the tank cover 2 around the receiving hopper 3. There are several air outlets 21, which are evenly distributed on the tank cover 2.

[0023] A spiral pipe 4 is fixedly connected inside the cooling tank 1. The spiral pipe 4 has several through holes 41, which are evenly distributed on the spiral pipe 4. A discharge pipe 8 is fixedly connected to the outside of the cooling tank 1. The upper end of the spiral pipe 4 is fixedly connected to the receiving hopper 3, and the lower end is fixedly connected to the discharge pipe 8. The outside of the spiral pipe 4 is in contact with the inner wall of the cooling tank 1. Under the action of the through holes 41, it is convenient for air to enter the spiral pipe 4 to cool the plastic particles.

[0024] A partition 5 is fixedly connected to the inner wall of the cooling tank 1 located below the spiral pipe 4. A motor 6 is fixedly connected to the bottom of the cooling tank 1 located below the partition 5. Several openings 51 are provided on the upper side of the partition 5. There are five openings 51, which are evenly distributed on the partition 5. There are five motors 6, which correspond one-to-one with the openings 51. A fan blade 61 is fixedly connected to the output end of the motor 6. The fan blade 61 is located inside the opening 51. Under the action of the motor 6 and the fan blade 61, the air is blown upward from the bottom of the cooling tank 1 to cool it. The lower the plastic particles move, the better the cooling effect.

[0025] A wind column 9 is fixedly connected to the opening 51 located in the middle of the partition 5. The wind column 9 is located in the middle of the spiral pipe 4 and has air holes 91 around it. Under the action of the wind column 9, the air is dispersed from the middle to the outer periphery to cool the plastic particles. The air is cooled to cool the plastic particles in different directions, so that the cooling effect is better. The cooling tank 1 located outside the motor 6 is provided with heat dissipation vents 7. There are several heat dissipation vents 7, which are evenly distributed around the cooling tank 1. A dustproof net 71 is fixedly connected inside the heat dissipation vent 7 to prevent the intake of external dust.

[0026] In another embodiment, while the motor 6 is cooling the plastic particles, the dust on the plastic particles can be cleaned. The motor 6 drives the fan blades 61 to blow the dust off the plastic particles and discharge it through the air outlet 21.

[0027] Working principle: When in use, first start the motor 6, which drives the fan blade 61 to rotate. Then move the device to the discharge port of the plastic granule production device. When the plastic granules are produced, they fall into the receiving hopper 3 and then enter the spiral pipe 4. At this time, under the action of the motor 6 and the fan blade 61, the air is blown upward from the bottom of the cooling tank 1 to cool them. The lower the plastic granules move, the better the cooling effect. At the same time, under the action of the air column 9, the air is dispersed from the middle to the outer periphery to cool the plastic granules. The air is cooled on the plastic granules in different directions, which makes the cooling effect better.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 utility model.
