Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically to a high-temperature premixing device for raw materials used in plastic production. Background Technology

[0002] Plastic production is a complex process, typically involving multiple stages such as raw material preparation, molding, and post-processing. For various types of plastic raw materials or different batches, high-temperature premixing helps them blend better. High temperatures bring the raw materials to a molten or semi-molten state, reducing their viscosity and increasing molecular mobility, thereby promoting interpenetration and mixing between the materials and improving the overall performance of the plastic.

[0003] High-temperature premixing devices for raw materials are needed in the plastic production process. Chinese utility model patent CN216782310U discloses a raw material premixing device for plastic production, including a main body with a guide rod fixedly connected to it. It also includes a power module, a displacement mixing frame module, and a bottom material guiding module. The power module, installed inside the main body, drives the displacement mixing frame module. The displacement mixing frame module includes a telescopic mixing frame structure and a compression structure. The compression structure is connected to the power module, and the telescopic mixing frame structure and the compression structure are hinged together. An elastic element is installed between the telescopic mixing frame structure and the compression structure. The bottom material guiding module is fixedly installed on one side of the telescopic mixing frame structure. This utility model enhances the mixing effect of plastics through the dual functions of displacement mixing and bottom material guiding.

[0004] However, during use, the device does not have a structure for treating the flue gas. When the plastic raw materials are melted at high temperature, a large amount of flue gas is generated. This flue gas contains a certain amount of irritating gases, which will cause a large amount of odor to be emitted in the entire production workshop, affecting production efficiency and failing to meet production needs. Therefore, a high-temperature premixing device for plastic raw materials is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature premixing device for raw materials in plastic production. It has the advantage of facilitating the treatment of flue gas and solves the problem that existing premixing devices do not have a structure for treating flue gas. When plastic raw materials are melted at high temperatures, a large amount of flue gas is generated. This flue gas contains a certain amount of irritating gases, which causes a large amount of odor to be emitted throughout the production workshop, affecting production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature premixing device for raw materials used in plastic production, comprising a mixing tank and a sealing cover plate fixedly connected to the top of the mixing tank, wherein a processing box is fixedly installed on one side of the mixing tank, and the interior of the processing box is provided with a flue gas treatment structure capable of treating the flue gas in the mixing tank;

[0007] The flue gas treatment structure includes an exhaust pipe fixedly connected between the mixing tank and the treatment box. The treatment box contains an absorbent and a guide bucket. An activated carbon adsorption plate extending to the back of the treatment box is slidably connected to the inside of the treatment box. An exhaust pipe communicating with the inside of the treatment box is fixedly connected to the top of the treatment box.

[0008] Furthermore, the end of the exhaust pipe away from the mixing tank is located at the bottom of the back of the treatment box, and a drain pipe extending into the interior of the treatment box is fixedly connected to one side of the treatment box.

[0009] Furthermore, positioning strips extending into the interior of the treatment box are fixedly connected to both sides of the activated carbon adsorption plate, and positioning grooves adapted to the positioning strips are provided on the inner wall of the treatment box.

[0010] Furthermore, a heating inner liner is fixedly connected inside the mixing tank, and a heating sleeve is fixedly connected between the heating inner liner and the mixing tank.

[0011] Furthermore, a stirring motor is fixedly installed on the top of the sealing cover, and a stirring rod extending into the mixing tank is fixedly connected to the output shaft of the stirring motor.

[0012] Furthermore, a feed pipe communicating with the inside of the mixing tank is fixedly connected to the top of the sealing cover, and a thermometer extending into the inside of the mixing tank is fixedly connected to the top of the sealing cover.

[0013] Furthermore, a discharge pipe extending into the bottom of the mixing tank is fixedly connected, and valves are fixedly connected to both the exhaust pipe and the discharge pipe.

[0014] Furthermore, the front of the mixing tank is fixedly connected with three support rods extending to its bottom, and the three support rods are evenly distributed on the outside of the mixing tank.

[0015] Compared with the prior art, this utility model provides a high-temperature premixing device for raw materials in plastic production, which has the following beneficial effects:

[0016] 1. This high-temperature premixing device for raw materials used in plastic production can transport the flue gas generated inside the mixing tank to the treatment box through the exhaust pipe. Then, by setting up absorbent and activated carbon adsorption plates, it can treat the odors and harmful substances in the flue gas, thereby preventing a large amount of odor from being emitted in the production workshop. At the same time, by setting up a guide plate, it can prevent the flue gas treated by the absorbent from flowing back, thus improving the flue gas treatment efficiency.

[0017] 2. This high-temperature premixing device for plastic production raw materials, by setting up a heating inner tank and heating sleeve, can realize the melting treatment of plastic raw materials inside the mixing tank. At the same time, the stirring motor drives the stirring rod to rotate, which can realize the mixing treatment. This solves the problem that existing premixing devices do not have a structure to treat the flue gas. When the plastic raw materials are melted at high temperature, a large amount of flue gas is generated. This flue gas contains a certain amount of irritating gases, which will cause a lot of odor to be emitted in the entire production workshop, affecting production efficiency.
