Description

Technical Field

[0001] This utility model belongs to the field of mica paper processing, and in particular relates to a drying device for mica paper processing. Background Technology

[0002] The production process of mica paper mainly includes pulp preparation in the storage tank, papermaking and forming in the wire section, dewatering in the press section, drying in the drying section, and winding into tubes. Drying in the drying section refers to the process where the mica paper, after being dewatered by the press, enters the drying section and is dried to remove residual moisture, making it a suitable insulating material for electrical appliances. This step is crucial in ensuring the final performance of the mica paper; each step is essential and together they ensure the quality and performance of the final product.

[0003] Comparing with Chinese Patent CN205100028U, a rapid and uniform drying device for mica paper processing is disclosed, including a frame and a drying drum and a drying hood mounted on it. Suspension rods are installed on both sides of the front end of the frame; the drying drum is installed between the suspension rods; a telescopic hydraulic cylinder is installed at the front end of the frame; a semi-circular drying hood is installed at the front end of the telescopic hydraulic cylinder; the drying drum is located inside the drying hood; a hot air blower is connected to the upper end of the outer wall of the drying hood; an exhaust pipe is connected to the tail end of the hot air blower; a steam suction trough is installed at the top of the drying hood; the steam suction trough is connected to the exhaust blower through a steam telescopic pipe; the exhaust blower is located at the upper end of the frame; a measuring rod is also installed between the suspension rods and between the drying hood and the drying drum; a temperature / humidity sensor is installed on the measuring rod; a control panel is installed on the frame. This device can intelligently adjust the drying intensity of the mica paper, ensuring the mica paper is at the optimal drying level, with fast and uniform drying speed, convenient use, and flexible adjustment, greatly improving production efficiency.

[0004] However, the aforementioned patents suffer from inconsistent drying of mica paper during its movement, and the drying hoods do not use a uniform temperature to dry the mica paper, which reduces the uniformity of the drying process. Therefore, a new type of equipment needs to be designed. Utility Model Content

The condensed wastewater is discharged from the waste discharge pipe 207 under pressure.

[0029] In this embodiment: the auxiliary heating component includes a heat-concentrating cover 301, with 20 sets of drying lamps 302 evenly distributed on the inner top surface of the heat-concentrating cover 301, each with independently controlled heating temperature; four height adjustment mechanisms are evenly distributed at the four corners of the heat-concentrating cover 301; the adjustment mechanism includes connecting seats 303 at the four corners of the heat-concentrating cover 301, support rods 304 on the sides of the connecting seats 303, a plurality of limiting holes 306 evenly distributed on the support rods 304, and fixing bolts 307 installed between the connecting seats 303 and the support rods 304; a fixing seat 305 is provided at the bottom end of the support rods 304, and the fixing seat 305 and...
