[0002] Plastic is a common material in life, and modified plastic refers to plastic products whose properties such as flame retardancy, strength, impact resistance, and toughness have been improved through methods such as filling, blending, and reinforcement on the basis of conventional plastics such as general-purpose plastics and engineering plastics.

[0003] The Chinese patent with the publication number CN219748604U discloses a high-efficiency plastic particle hot melting device, belonging to the field of plastic particle processing. The high-efficiency plastic particle hot melting device includes a machine shell with a cavity structure inside, a purification mechanism, a power mechanism, the power mechanism is arranged on one side of the machine shell, and a feeding mechanism, the feeding mechanism is arranged on the upper side of the machine shell. By using this device, the problems that the traditional high-efficiency plastic particle hot melting device cannot improve the working efficiency of the device by reducing the heat generated by itself, and the harmful gases generated by the traditional high-efficiency plastic particle hot melting device are discharged, and at the same time, the problem that the harmful gases discharged excessively by the device cause environmental pollution and endanger the physical health of the staff are solved.

[0004] To sum up, the above patent feeds plastic particles by setting a receiver. However, since its feeding position is fixed, when feeding, the plastic particles will be concentrated and piled up at one position inside the hot melting machine. This will cause the central area of the plastic particles piled up inside to be unevenly heated, and then the hot melting speed will become low, affecting the operation efficiency. Secondly, since the flue gas temperature of the plastic particles is relatively high during the hot melting process, although the above patent can filter and purify the flue gas, it cannot cool the flue gas, which will cause high-temperature gas to be discharged, affecting the atmospheric temperature and the environment.

A spray pipe is further fixed inside the purification tank, and a filter module is arranged on the top of the purification tank.

[0017] In the above technical solution, when melting plastic particles, high-temperature gas will enter the purification box through this exhaust pipe, and the spray pipe located above the exhaust pipe can spray water mist downward, so that it can cool down and remove dust from the upward flowing high-temperature flue gas, avoiding the impact of the discharged high-temperature flue gas on the room temperature environment, and the cooled flue gas will be discharged after being filtered by this filter module.

[0018] Preferably, the inner bottom of the purification box is a water storage tank, and a delivery pump is installed in the water storage tank. The delivery pump is connected to the spray pipe through a delivery pipe.

[0019] In the above technical solution, through this delivery pump, the water in the water storage tank can be delivered to the spray pipe, so that the spray pipe can spray water mist downward to cool the flue gas, and the sprayed water mist will fall back into the water storage tank again to achieve the purpose of recycling.
