Description

Technical Field

[0001] The utility model relates to the technical field of fume treatment of extruders, in particular to a fume treatment device of a cable insulation layer extruder. Background Art

[0002] Cables are generally composed of an insulating protective sheath wrapped around a conductive cable core. The general production process is: the conductive cable core is placed on a pay-off reel, and under the traction of a traction machine, it is wrapped with an insulating protective sheath at 200°C at the die of the extruder, and then the high-temperature insulating protective sheath is directly placed in a cooling water tank at room temperature. When the cable passes through the extruder, the high temperature of the extruder melts the plastic raw materials and covers the outside of the cable. When the extruder melts the solid plastic, it will produce a variety of toxic waste gases and dust, and direct emissions are very harmful to employees and the environment.

[0003] After searching, it is found that a Chinese patent document discloses a fume treatment device for a cable insulation layer extruder [application number: CN202122070499.1]. This fume treatment device for a cable insulation layer extruder includes a sliding lifting fixed frame installed on the cable insulation layer extruder; a dust hood installed on the sliding lifting fixed frame; a conveying pipe, one end of which is connected to the dust hood; an exhaust fan installed on the conveying pipe; and a filtering mechanism, the other end of the conveying pipe is connected to the filtering mechanism.

[0004] The device disclosed in the patent can process the smoke of the extruder when in use, thereby preventing the smoke from being directly discharged and affecting employees and the environment. The device is provided with a filter plate and an activated carbon plate, so that dust and odor can be processed. However, when the filter plate and the activated carbon plate are in use, dust can easily clog the filter plate, thereby affecting the normal operation of the filter plate. After the activated carbon plate has been used for a period of time, it is necessary for the staff to replace it. However, the device is not convenient for repairing and replacing the filter plate and the activated carbon plate, resulting in low practicality. Utility Model Content
