Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a pretreatment device for modified plastic particles. Background Technique

[0002] Modified plastics refer to a kind of plastic material that makes plastics have better performance and functions by adding other substances or changing the molecular structure of plastics. They are widely used in fields such as household appliances, automobiles, communications, medical treatment, and electronic and electrical. During the storage of modified plastics, if the packaging is not tight or the sealing effect is not good, it is very easy for plastic particles to get damp, which will cause phenomena such as cracking, holes, bubbles, dents, and water patterns in the plastic products during the processing. Therefore, it is necessary to carry out pretreatment such as drying on the plastic particles before processing.

[0003] A Chinese patent with the publication number of CN214056017U discloses a pretreatment device for the production of plastic particle compression products, including a barrel body, and a filter plate is fixedly installed inside the barrel body. For this pretreatment device for the production of plastic particle compression products, by starting the ultrasonic transducer, the agglomerated plastic particles are vibrated and dispersed, by starting the air pump, the humid gas in the barrel body is pumped into the box body, the electric heating wire is turned on to heat and dry the gas, the hot air enters the barrel body through the air delivery pipe, and the rotation motor is started to drive the stirring rod and the stirring blade to stir the plastic particles in the barrel body. Along with the stirring, the hot air circulates and heats the plastic particles, so that the plastic particles are dried sufficiently. In this way, the plastic particles are subjected to moisture-proof and dispersion treatment before production, avoiding the phenomenon of agglomeration of plastic particles due to moisture during production, greatly improving the quality of plastic particle compression products and being convenient for use.

[0004] To sum up, the above patent generates hot air through the electric heating wire, and stirs the plastic particles in the barrel body through the motor, the stirring rod and the stirring blade. Along with the stirring, the hot air circulates and heats the plastic particles, so that the plastic particles are dried sufficiently. However, in this drying method, the plastic particles will be dried in the stacked barrel body. When the plastic particles are stacked together, it will cause the hot air to be unable to circulate. Even though there is a stirring rod to stir the plastic particles, the hot air still cannot penetrate into the stacked plastic particles, which will result in a long drying time and low drying efficiency. Secondly, due to the stacking of plastic particles, under the action of extrusion and abrasion, some plastic particles will have the situation of powder and slag falling off. And the above patent is not convenient for screening the plastic particles, which will cause dust to disperse during discharging and thus affect the environment. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-3 , the present invention provides a technical solution: a modified plastic particle pretreatment device, as Figure 1 , Figure 2 and Figure 3 shown, a drying box 2 is fixed on the top of the base 1, and feed inlets 3 are opened at both ends of the top of the drying box 2. Partition boards 4 are fixed at both ends inside the drying box 2, and deflector plates 5 are fixed on the inner wall of the drying box 2 and the side walls of the partition boards 4. A discharge gate 6 is further provided at the bottom of the drying box 2;

[0030] A feeding mechanism 7 is arranged between the two groups of partition boards 4;

[0031] A drying mechanism 8 is arranged outside the drying box 2.

[0032] The feeding mechanism 7 includes a motor 1 701, the motor 1 701 is fixed at the midpoint of the top of the drying box 2, and the output end of the motor 1 701 is connected to a rotating rod 702. The rotating rod 702 is installed on the top of the inner wall of the drying box 2, and the rotating rod 702 is located between the two groups of partition boards 4. An auger 703 is fixed on the rotating rod 702.

[0033] The drying mechanism 8 includes a hot air blower 801, the hot air blower 801 is fixed outside the drying box 2, and the hot air blower 801 is connected to an exhaust air plate 803 through a delivery pipe. The exhaust air plate 803 is installed at the bottom of the inner wall of the drying box 2.

[0034] The bottom of the inner wall of the drying box 2 is conical.

[0035] Blowers 9 and baffles 10 are respectively installed at both ends inside the base 1, and filter bags 11 are arranged above the baffles 10. A conveyor belt 12 is installed at the inner bottom of the base 1.

[0036] A second motor 13 is fixed to the outer side of the base 1, and the output end of the second motor 13 is connected to the dispersion roller 14. The dispersion roller 14 is installed inside the base 1 and is located below the discharge gate 6.

[0037] Working principle: During use, plastic particles are discharged into the drying box 2 from the feed inlet 3. Then, the hot air blower 801 can be turned on to generate hot air, and the hot air is conveyed through the conveying pipe into the exhaust air plate 803, causing the exhaust air plate 803 inside the drying box 2 to blow out hot air upward. Then, the first motor 701 can be turned on to drive the rotating rod 702 and the auger 703 to rotate, so that the auger 703 between the two partition plates 4 conveys the plastic particles at the bottom of the drying box 2 upward. After that, the plastic particles will slowly fall through the deflector 5, reducing the falling speed of the plastic particles. When the plastic particles fall to the bottom of the drying box 2, the auger 703 will continuously convey the plastic particles upward without stopping, causing the plastic particles to circulate and flow from top to bottom for drying. When the drying is completed, the discharge gate 6 can be opened to discharge the plastic particles into the base 1. During this process, the blower 9 can be turned on to blow the relatively light plastic dust or debris into the filter bag 11 through the blowing, and the second motor 13 can be turned on to drive the dispersion roller 14 to rotate, causing the dispersion roller 14 to strike the plastic particles and improving the dispersion degree of the plastic particles during the falling process. This can better remove impurities from the plastic particles by blowing and improve the impurity removal effect. Then, the falling plastic particles will be discharged through the conveyor belt 12 for unloading.
