Description
Technical Field
[0001] This utility model relates to the technical field of silk processing equipment, and in particular to an exhaust device for silk drying equipment. Background Technology
[0002] In the silk processing industry, drying is a crucial and technically sensitive final step. Its purpose is to remove excess moisture from the wet silk sheets, which still contain a lot of water after processes such as boiling cocoons, reeling, and rewinding, through controlled heat, so that they reach the specified moisture regain rate. This facilitates long-term storage and transportation and maintains the excellent mechanical properties, unique luster, and hand feel of the silk fibers.
[0003] Traditional silk drying mainly relies on drying rooms or box-type drying equipment, which heat and dry the silk through hot air circulation convection. In this process, the exhaust system, as one of the core components of the drying system, directly affects the drying efficiency, energy consumption, and the quality of the final silk product.
[0004] When the drying equipment is working, hot air flows over the wet silk, absorbing moisture from the surface of the silk fibers. The air's temperature decreases and its humidity increases, gradually becoming saturated or nearly saturated humid air. Traditional equipment often uses a simple fan to directly exhaust the highly humid air outdoors. While this method provides direct dehumidification, it results in significant energy loss by directly expelling heat-containing exhaust gas. Utility Model Content

A first humidity sensor and a temperature sensor are fixedly connected to the inside of the door of the drying oven. An exhaust fan is fixedly connected to the top wall of the heat-insulating hood. Multiple baffles are provided below the exhaust fan, and the multiple baffles are fixed in a figure-eight shape inside the heat-insulating hood.

The preheated dry hot air is returned to the drying box for reuse through the insulation circuit, which significantly reduces the energy demand for heating fresh air and has a significant energy-saving effect.
[0014] 2. Compared with existing technologies, the exhaust device of this silk drying equipment uses a second humidity sensor to monitor the saturation state of the drying blocks in real time, realizing intelligent perception of the desiccant status. This replaces the traditional method of relying on experience or timed judgment. The drying blocks adopt a modular design and are quickly clamped and fixed with locking components. When replacement or regeneration is required, the operator can easily pull the entire drying block module out of the insulation box for replacement or offline drying and regeneration. Maintenance and operation are simple and quick, ensuring the efficiency of continuous operation of the equipment. The exhaust fan and the figure-eight baffle inside the insulation hood work together. The baffle can effectively disperse the airflow, so that the returned hot air mixes more fully with the hot air in the box, avoiding hot air blowing directly on the silk. At the same time, the exhaust fan provides stable power for the entire exhaust gas circulation system. Attached Figure Description

The material hanging component includes two guide blocks 8 symmetrically and slidably connected to the rear wall of the drying chamber 1. Multiple hanging rods 7 are horizontally fixed on the front side of the guide blocks 8. Two guide rods 15 are slidably inserted through the top surfaces of the two guide blocks 8. The guide rods 15 are fixed inside the drying chamber 1. A screw 16 is threaded through the two guide blocks 8. One end of the screw 16 is rotatably connected to the bottom wall of the drying chamber 1, and the other end rotatably passes through the top surface of the drying chamber 1. A drive motor 13 is fixedly connected to the top surface of the drying chamber 1. The output end of the drive motor 13 is connected to the end of the screw 16 for transmission.
[0019] Working principle: In use, the damp silk is hung on the outer edge of the hanging rod. Then, the drive motor 13 drives the two guide blocks 8 to move in opposite directions through the screw 16, so that the silk is taut. After the equipment is started, the fan draws in air, which is heated by the heating mesh 5 to form hot air, which is sent into the drying chamber 1. The hot air passes through the damp silk sheets suspended on the hanging rod 7, absorbs moisture, and becomes high-temperature and high-humidity exhaust gas. Under the suction of the induced draft fan, the high-temperature and high-humidity exhaust gas enters the heat preservation chamber from the air outlet 17 at the back of the drying chamber 1. 10. The exhaust gas rises through the drying block 21, which is made of a highly efficient moisture-absorbing material (such as silica gel, molecular sieves, etc.). Multiple pores inside the drying block increase the contact area with the exhaust gas. During this process, a large amount of moisture in the exhaust gas is adsorbed by the drying block 21. Simultaneously, the condensation and adsorption processes release adsorption heat, heating the gas. Therefore, the wet exhaust gas is converted into dry, hot air with a higher temperature and lower humidity. The second humidity sensor 26 monitors the humidity of the air below the drying block 21 or the humidity of the drying block 21 itself in real time. The state is used to determine whether the drying block 21 is approaching saturation. The dry, hot air, after being dehumidified and reheated by the drying block 21, gathers at the top of the insulated box 10 and is transported to the insulated air hood 14 through the insulated pipe 12. Inside the insulated air hood 14, the figure-eight shaped baffle 18 ensures that the air is fully mixed with the ambient air inside the box. Driven by the induced draft fan, the air is then blown back into the top of the drying box 10 to participate in the next drying process. This forms a closed-loop (or semi-closed-loop) system in which most of the waste gas heat and some moisture are recovered and reused, greatly reducing the heat loss. With less energy loss from atmospheric discharge and less energy consumption from fresh air heating, the equipment can issue an alarm when the second humidity sensor 26 detects a decrease in the adsorption capacity of the drying block 21. Maintenance personnel can pull the second pull block 25 upwards to disengage the second positioning block 29 from the second positioning groove 28, allowing the sealing plate 11, along with the internal U-shaped plate 23 and the saturated drying block 21, to be extracted from the insulation box 10. Afterwards, a new drying block 21 module can be replaced, or the saturated module can be moved to a dedicated device for drying and regeneration. The operation is simple and the maintenance efficiency is high.
