4results about How to "Reduce drying load" patented technology

The utility model discloses a drying device for cable production, and relates to the technical field of cable production. The device comprises a box body, a hot air drying assembly and a vibration dewatering assembly, a positioning frame is fixedly connected between the front side and the rear side of an inner cavity of the box body, the top of the positioning frame is communicated with a hot air conveying mechanism, and the hot air drying assembly comprises a rotating sleeve. Through the hot air drying assembly, hot air exhausted from the exhaust opening can continuously act on the surface of the cable in a multi-angle mode through rotating cooperation of the rotating sleeve and the exhaust pipe, water drops on the surface of the cable are rapidly dried through rotating airflow, the drying time is effectively shortened, and the hot air coverage range is enlarged; and meanwhile, the rotating mechanism drives the exhaust pipe to uniformly rotate, so that the hot air acting strength of different areas is consistent, local moisture residues are avoided, and the influence of the moisture residues on the subsequent processing steps of the cable is prevented.

The utility model discloses a weftless tape production device, which belongs to the technical field of weftless tape production, and comprises a creel, a yarn guide hook, an immersion tank, a drying box, a winding mechanism and a liquid removal mechanism, a plurality of pagoda yarns are arranged on the creel, and a roll of fiber silk yarn is arranged on each pagoda yarn; a resin matrix is contained in the immersion tank; the yarn guide hook is used for guiding fiber silk threads on the pagoda yarn to enter the immersion tank in parallel for immersion; the drying box is used for drying the fiber silk threads soaked in the resin matrix so as to form a semi-dry pre-impregnated adhesive tape; the winding mechanism is used for winding and storing the semi-dry prepreg adhesive tape, and the liquid removing mechanism is located on the upstream of the drying box and used for conducting liquid removing treatment on the fiber silk threads obtained after the resin matrix is soaked. According to the utility model, the fiber silk yarn before entering the drying box is subjected to liquid removal treatment, so that the amount of a resin matrix carried into the drying mechanism is reduced, the drying load of the unit is favorably reduced, and meanwhile, the loss of the resin matrix in the immersion liquid tank is reduced.

The application provides a quasi-dry method for preparing an electrode sheet, a battery electrode sheet and a lithium ion battery, and relates to the field of lithium ion battery preparation. The quasi-dry method for preparing an electrode sheet comprises the following steps: mixing an active material, a conductive agent, a solvent and a binder to obtain a composite; drying the composite after arranging the composite on a current collector; and rolling to obtain an electrode sheet; wherein the composite is a paste-like composite; and the solid content of the composite is 76-95%. Compared with the prior art, the method for preparing a battery electrode sheet provided by the application effectively avoids the problems of easy delamination and large interface resistance of the pure dry method process, and avoids the defects of difficulty in densification due to drying shrinkage of a thick electrode in a wet method.

The utility model discloses a drying device for chemical product production, which comprises a drying box, an air heater, a dewatering box and an upper cover, a rotary drum, an air outlet box and a plurality of support plates are arranged in the drying box, and a discharge pipe and an air outlet pipe which are communicated with the interior of the drying box are arranged on the drying box. A dewatering mechanism used for removing moisture in the product is arranged in the dewatering box, the dewatering mechanism comprises a screen drum rotationally connected to the side wall of the upper cover, a first motor is fixedly connected to the lower end of the dewatering box, and an output shaft of the first motor is fixedly connected with a rotating shaft. The dehydration mechanism is arranged, the water content of materials can be reduced through pre-dehydration of the dehydration box, the drying load is relieved, meanwhile, the drying time can be shortened, and energy consumption can be reduced.
