Description

Technical Field

[0001] This utility model relates to the technical field of rubber additive production, and in particular to a novel environmentally friendly drying device for rubber additive production. Background Technology

[0002] Rubber additives originated from the vulcanization of natural rubber. They play an important role in synthetic rubber formulations and are also a major factor affecting the performance of rubber products. Dryers are often used to dry rubber additives during the processing.

[0003] Existing drying devices, such as the environmentally friendly rubber additive production drying device disclosed in utility model patent application number 202222735329.5, mainly include a conveying chamber inside the shell, a heat dissipation chamber above the conveying chamber, a grid plate on the side surface of the heat dissipation chamber, a motor fixedly connected to the left side of the shell, an auger roller fixedly connected to the output end of the motor, a drying mechanism inside the top of the heat dissipation chamber, and an air outlet pipe fixedly connected to the lower surface of the distribution pipe. In use, the rubber additive is added to the conveying chamber through the feed port, and the rubber additive is conveyed and turned by the auger roller. The hot air is started by an external power supply, and impurities in the air are filtered through the filter box. The generated hot air is then input into the distribution pipe through the second pipe, and then poured into the heat dissipation chamber through the air outlet pipe. The heat dissipation chamber allows the hot air to come into uniform contact with the conveyed and turned rubber additive.

[0004] However, most existing drying devices only use hot air to heat and dry rubber additives, resulting in low drying efficiency. Moreover, most existing drying devices do not remove moisture in time, which also affects the drying effect and wastes heat. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a new type of environmentally friendly drying device for rubber additive production that not only utilizes heating plates and hot air to heat and dry materials simultaneously, thus improving drying efficiency, but also promptly extracts moisture from the device and utilizes the residual heat in the extracted air, thereby improving energy utilization.

[0006] This utility model discloses a novel environmentally friendly drying device for producing rubber additives, comprising a heating mechanism; it also includes a sealing mechanism, a stirring mechanism, an air supply mechanism, and a preheating mechanism. The sealing mechanism is installed on the heating mechanism and seals the device; the stirring mechanism is installed on the heating mechanism and stirs the material; the air supply mechanism is installed on the heating mechanism and delivers hot air into the heating mechanism; and the preheating mechanism is installed on the heating mechanism and extracts moisture from the device. The device is operated by opening the sealing mechanism, adding the material into the heating mechanism, then closing the sealing mechanism to prevent outside air from entering the heating mechanism. The stirring mechanism is then activated to stir the material, ensuring uniform heating. The air supply mechanism is then activated to deliver heated air into the heating mechanism to assist in drying. Simultaneously, the preheating mechanism is activated to extract the evaporated moisture after drying and preheat the air in the air supply mechanism.

The hinge is installed on the feed pipe, the sealing cap is installed on the hinge, the handle is installed on the sealing cap, and the sealing ring is installed on the sealing cap. The operator pulls the handle to open the sealing cap, allowing the material to be conveyed into the cavity of the heating cylinder through the feed pipe. Then, the operator pushes the handle to close the sealing cap on the feed pipe. The sealing ring enhances the sealing effect of the sealing cap, preventing outside air from entering.

[0009] Preferably, the stirring mechanism includes a motor, a reducer, a drive shaft, a first pulley, a hollow rotating shaft, a second pulley, a belt, and three sets of hollow scrapers.

The air supply mechanism delivers hot air to the hollow rotating shaft and the interior of the three sets of hollow scrapers. The three sets of hollow scrapers can heat the material while stirring it, making the material heat more evenly. The tangential contact between the hollow scrapers and the inner wall of the heating cylinder can prevent the material from sticking to the inner wall of the heating cylinder.
