Raw material conveying device for production of modified bituminous waterproof sheet

Abstract

The invention discloses a raw material conveying device for the production of a modified bituminous waterproof sheet. The raw material conveying device comprises a burdening box and a conveying cylinder; a feeding pipe is mounted on the bottom wall of the burdening box; a sleeve sleeves one end, close to the conveying cylinder, of the feeding pipe; the other end of the sleeve is mounted on the topwall, close to the burdening box, of the conveying cylinder; a limiting plate is mounted on the side wall, close to the bottom end, of the feeding pipe; a limiting groove matched with the limiting plate is formed in the inner wall of the sleeve; a first motor is mounted on the top wall of the burdening box; a charging pipe is mounted on one side of the burdening box; and two stirrers are rotationally connected into the burdening box. Bituminous raw materials are sufficiently mixed through the arrangement of all structures, the fluidity of the raw materials is improved, the condition that theraw materials are accumulated to block a pipeline is avoided, moreover, the stable conveying quantity and the stable conveying speed of the raw materials are kept, conveying points and conveying angles of the device can be adjusted, the actual operational requirement is met, and the flexibility of the device is improved.

Description

technical field [0001] The invention relates to the technical field of waterproof membranes, in particular to a raw material conveying device for the production of modified asphalt waterproof membranes. Background technique [0002] The modified asphalt waterproofing membrane is made of SBS rubber modified petroleum asphalt as the impregnated covering layer, made of polyester fiber non-woven fabric, jute cloth, glass fiber mat, etc. as the base, and plastic film as the anti-stick isolation layer , processed through material selection, ingredients, co-melting, impregnation, composite molding, curling and other processes. [0003] In the production process of modified asphalt waterproofing membrane, the conveying device needs to be used to transport and feed the asphalt raw materials. In the existing technology, when the asphalt raw materials are transported, the pipeline is prone to be blocked by raw material accumulation, and the conveying speed and volume are unstable. The...
