Description

Device for uniformly baking glass fiber yarn clusters of each layer in drying furnace Technical Field The utility model relates to the technical field of drying furnaces, in particular to a device for uniformly drying glass fiber yarn groups of each layer in a drying furnace. Background In the industrial production of glass fiber, the glass fiber is wet yarn group after wiredrawing and shaping, and needs to be dried into dry yarn group, then the subsequent packaging and winding processes can work normally, and in the drying process, the existing single-area natural gas or steam heat exchanger is often limited by a compact main body space (the more compact main body space is, the more concentrated heat quantity is), and generally, some heat exchangers with smaller volumes and smaller power are selected. When a single-zone natural gas or single-zone steam heat exchanger drying furnace is used for drying products with heavier wet base yarn groups and shorter drying time, as the wet base water content is higher, the furnace door is frequently opened, cold air enters more, heat generated by heat exchange of the single-zone heat exchanger can not reach the rising temperature, heated air expands and rises according to a physical rule, and the film forming time of the lower layer of the cooled air is shorter than that of the upper layer of the cooled air, so that the quality of the products can not meet the process requirement, and hidden quality hazards exist. Disclosure of utility model The utility model aims to provide a device for uniformly baking glass fiber yarn groups in each layer in a drying furnace, which can avoid the problem of shorter film forming time of a lower layer product of a yarn car caused by insufficient heat exchange capacity of a heat exchanger in a single region of the drying furnace, is beneficial to reducing hidden quality hazards of baked products, improves the baking effect of the products and enhances the quality stability of the products. In order to achieve the purpose, the utility model provides a device for uniformly baking each layer of glass fiber yarn groups in a drying furnace, which comprises the drying furnace, wherein one side of the drying furnace is provided with a wet base yarn group yarn car, and a circulating fan acting downward air channel and a wet pumping fan working air channel are arranged in a single area in the drying furnace; A heat exchanger is also arranged on the drying furnace; the drying furnace further comprises an inclined-plane guide plate and a mounting assembly, wherein the inclined-plane guide plate is 30 degrees away from the horizontal surface of the bottom in a single area of the drying furnace after being mounted by the mounting assembly, an inclined-plane guide air channel is formed after the inclined-plane guide plate is arranged, and the mounting assembly is arranged below the inclined-plane guide plate. Wherein, the size of the inclined plane deflector can be set according to the different single-zone sizes of the drying furnace. The mounting assembly comprises a 30-degree base, a connecting block and a limiting member, wherein the 30-degree base is detachably mounted at the inner bottom of a single area of the drying furnace, the connecting block and the inclined-plane guide plate are integrally formed and provided with inserting round holes, and the limiting member is arranged at one side, close to the connecting block, of the 30-degree base. The limiting component comprises a bolt and a clamp spring, wherein the bolt is T-shaped and can be inserted into an insertion round hole of the connecting block and a through hole of the 30-degree base respectively, and the clamp spring is mounted on the bolt and is abutted to the 30-degree base. The peripheral contact surfaces of the inclined plane guide plates are respectively sealed by high-temperature flame-retardant sealant. According to the device for uniformly baking each layer of glass fiber yarn groups in the drying furnace, the inclined surface guide plate in the single area of the drying furnace is arranged, so that heat generated by the heat exchanger can be maximized, the original wind direction is the whole vertical wind direction with the top downward, the lower part is the inclined wind direction with the angle of 30 degrees, the hot wind direction is guided, the wind direction on one side of the corner of the furnace body which does not need excessive hot wind originally is directly guided to the lower layer of the yarn car which needs more hot wind, the hot wind loss is reduced, the problem that the heat exchange capacity of the heat exchanger in the single area of the drying furnace is insufficient, the film forming time of the lower layer of the yarn car is short is solved, the hidden danger of the baked product is reduced, the product baking effect is improved, and the quality stability of the product is enhanced.
