Embodiment 1

[0031] This embodiment is a continuous sintering furnace for glass fiber needle felt. According to the design requirements, the effective length of the sintering furnace is 2-4m, and the internal effective height is less than 300mm. Heating wires are installed in the furnace, and the voltage is 380 volts; the temperature reaches the process temperature of 650°C within one hour of operation; thus, the power of the sintering furnace is determined to be 72KW. The maximum working temperature of the sintering furnace is 800°C, and the maximum process temperature is set at 650°C.

[0032] This embodiment includes an uncoiling device, a sintering furnace, a winding and deviation correcting device, a temperature control cabinet, and a transmission device.

[0033] The sintering furnace 3 comprises a furnace body, a heating wire 17, a heat-resistant layer 18, an insulating layer 15, an insulating layer 16, a body of furnace frame 13, an outer skin 31, a quartz ceramic guide roller 22 a...

Abstract

A glass fiber needle-punched felt continuous sintering furnace, the heat-resistant layer of the furnace body is made of refractory cement bricks, the heat-insulating layer is made of light alumina bricks and ceramic wool, and the heat-insulating layer is made of high-silica glass fiber needle-punched felt and cloth. The unwinding mechanism and the rewinding rectifying device (5) are respectively located at both ends of the furnace body; the temperature sensor is located in the sintering furnace (3); the main transmission device of the transmission device connects the transmission motor (25), the upper driving roller ( 7) The lower driving roller (8) and the quartz ceramic guide roller (22) are connected in sequence; the winding transmission device connects the deviation correction guide roller (32), the front idler (11) and the rear idler (12) through the chain (26). It is connected with the winding motor (27); the main transmission device and the winding transmission device are located on the same side of the sintering furnace. The invention has good heat preservation performance, shortens the production time of the needled felt, improves the production efficiency, reduces the unit power consumption, is easy to operate, and can meet the requirements of different shrinkage ratios.

Description

technical field [0001] The invention relates to a device in post-treatment production of glass fiber, in particular to a continuous sintering furnace for glass fiber needle felt. Background technique [0002] The existing glass fiber needle felt sintering furnace mostly adopts resistance box type intermittent sintering furnace, and the working temperature is up to 500°C. The sintering furnace mainly includes a brick-concrete structure furnace body or a steel structure furnace body, a furnace door, a heating resistance wire, a heat-resistant layer, an insulation layer, a temperature control cabinet, a product placement rack, and a product placement rack entry and exit track. This type of furnace has large volume, low production efficiency, high energy consumption, rapid failure of product placement racks and in-out guide rails, easy pollution of products, inconvenient operation, and cannot produce products with high shrinkage rate. Contents of the invention [0003] In ord...
