Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying and sterilization conveying device based on steam waste heat recovery. Background Technology
[0002] In industries such as food, pharmaceuticals, and chemicals, the drying and sterilization of materials are critical steps in the production process. Traditional methods typically rely on electric heating or direct steam heating, which consumes a lot of energy and has low thermal efficiency. With increasing demands for energy conservation and environmental protection, the technology of using industrial waste heat for drying and sterilization has gradually gained attention. However, existing drying and sterilization devices still have shortcomings in terms of heat recovery efficiency, material heating uniformity, and equipment sealing. There is an urgent need for a high-efficiency, stable, and easy-to-maintain drying and sterilization conveying device to achieve energy recycling and improve production efficiency.
[0003] Currently, most common drying and sterilization equipment adopts a fixed drying chamber or conveyor belt structure, using electric heating tubes or boiler steam to heat the materials. Some improved equipment recovers some waste heat by adding heat exchangers, but the heat transfer efficiency is limited. Regarding piping connections, traditional equipment typically uses flanges or threaded interfaces to fix steam delivery pipelines and uses gaskets to prevent leaks. In addition, some equipment uses a static drying method, where materials are spread flat on trays or mesh belts, relying on hot air circulation for drying and sterilization; however, the tumbling effect is poor, easily leading to uneven heating.
[0004] Existing technologies suffer from cumbersome disassembly and assembly, and low thermal energy utilization. Traditional flange or threaded connection structures are cumbersome to disassemble and assemble, and are prone to problems such as aging of gaskets and loosening of connections under long-term high temperature and high pressure environments, leading to steam leakage.

A baffle is rotatably connected to the outer wall of the rotating shaft 1. A spring is fixedly connected to the outer wall of the baffle. A connecting pipe is attached to one end of the air inlet pipe.
[0007] Furthermore, a fixing plate is fixedly connected to the outer wall of the chamber cover, a motor is fixedly connected to the upper surface of the fixing plate, a connecting shaft is fixedly connected to the output end of the motor, a bottom plate is fixedly connected to the inner wall of the drying chamber, and a rolling component is provided at one end of the connecting shaft.
[0008] Furthermore, the rolling assembly includes a second roller, which is fixedly connected to one end of a connecting shaft. A storage tank is attached to the outer wall of the second roller, and a tank cover is fixedly connected to the outer wall of the storage tank. A limit ring is fixedly connected to the outer wall of the storage tank, and a first roller is attached to the outer wall of the limit ring. A second rotating shaft is rotatably connected to the inner wall of the first roller, and a fixing ring is fixedly connected to one end of the second rotating shaft.
[0009] Furthermore, the lower surface of the connecting plate is slidably connected to the outer wall of the retaining ring, and the inner wall of the retaining ring is fixedly connected to the outer wall of the connecting pipe.
[0010] Furthermore, the inner wall of the second retaining ring is fixedly connected to the outer wall of the air inlet pipe, and the outer wall of the second retaining ring is fixedly connected to the outer wall of the fixing block.
[0011] Furthermore, one end of the spring is fixedly connected to the inner wall of the second retaining ring, and the outer wall of the second retaining ring is attached to the outer wall of the first retaining ring.

[0013] Furthermore, the second roller is disposed inside the base plate, and the outer wall of the fixing ring is fixedly connected to the outer wall of the base plate.
[0014] This utility model has the following beneficial effects: 1. In this utility model, the connecting component utilizes the coordinated cooperation of a locking block, a locking ring one, a locking ring two, a baffle, and a spring to achieve quick disassembly and assembly and tight connection between the air inlet pipe and the connecting pipe. This improves the problems of poor sealing and inconvenient disassembly in traditional pipe connection methods, enhances the airtightness of the steam waste heat recovery system, avoids heat leakage, and ensures connection stability through a spring self-locking structure. This significantly improves equipment maintenance efficiency and reduces energy loss caused by loose connections.
[0015] 2. In this utility model, the motor drives the second roller in the rolling assembly to rotate the storage tank. With the dual limiting effect of the first roller and the limiting ring, the storage tank is heated evenly during the drying and sterilization process and is prevented from shifting laterally. This not only improves the efficiency of heat energy utilization, but also ensures that the material is heated evenly through the tumbling process. Thus, the sterilization effect and drying quality are significantly improved while saving energy and reducing consumption. Attached Figure Description

[0021] Working principle: When the device is needed, first place the support leg 1 on a flat ground to support the drying chamber 2.
