Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of filters, and particularly relates to a vacuum pump pipeline filter of a rubber extruder. BACKGROUND

[0002] In the production process of steel wire reinforced hydraulic hoses, a mandrel is used as a mold to obtain a stable inner diameter. In order to ensure that the inner rubber does not move or deform during the steel wire forming process, a vacuum pumping device is installed at the head of the rubber extruder during the extrusion of the inner rubber layer.

[0003] However, due to the use of saturated steam vulcanization, rust is generated inside the mandrel during long-term use. When the pipe head is cut, steel wire scraps and rubber powder are adsorbed on the inner surface of the mandrel, and are sucked into the vacuum pump under the action of negative pressure, causing the pump body to be damaged quickly. In addition, the rust has strong hygroscopicity and stacking property, and is adhered to the impeller of the water pump, affecting the operation effect of the water pump.
