Material proportioning device for preparation of modified-asphalt waterproof coil material

Abstract

The invention relates to a material proportioning device for the preparation of a modified-asphalt waterproof coil material. The material proportioning device comprises a material proportioning tank which is provided with a charging opening and a discharging opening, and a stirring device, wherein the stirring device comprises a driving motor, a stirring shaft which is driven to rotate by the driving motor, and a stirring paddle which is arranged on the stirring shaft. The material proportioning device is characterized in that the material proportioning tank is arranged in a manner of extending along the horizontal direction, the stirring shaft is arranged in the material proportioning tank along the extending direction of the material proportioning tank, and the stirring paddle comprises a plurality of spiral belts which are spirally wound on the stirring shaft along the extending direction of the stirring shaft. According to the material proportioning device disclosed by the invention, the phenomenon that the proportioned materials are non-uniform caused due to the sedimentation of the proportioned materials can be reduced effectively, meanwhile, the material proportioning tank can be fully used, the material proportioning efficiency is increased, and the material proportioning quality is guaranteed; in addition, the material proportioning device is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the field of equipment for preparing waterproof materials, and in particular relates to a batching device for preparing modified asphalt waterproof coiled materials. Background technique [0002] At present, the production of modified asphalt waterproofing membrane is divided into two parts, specifically the asphalt modification process and the membrane forming process. [0003] The whole production process as image 3 As shown, the description of the asphalt modification process: when preparing modified asphalt, the asphalt is measured and fed into the modified tank for asphalt heating. After the asphalt is heated to a certain temperature, modified materials, fillers and other materials are added for mixing. The final mixed material, that is, the modified bitumen, is used as the base material of the waterproof membrane into the membrane forming process. [0004] Therefore, the batching device plays a very important role in th...

Problems solved by technology

[0005] 1) For the vertical batching device, its batching tank is difficult to be fully utilized (especially the middle and upper part of the batching tank), that is to say, its effective volume is very small, resulting in a waste of resources;

[0006] 2) For the vertical batching device, the stirring shaft is also set vertically, and most of the stirring paddles are set horizontally or spirally wound. Specifically, the rotation of the paddle drives the ingredients to rotate around the stirring shaft. However, when the batching When some of the factors settle, the settled factors are all distributed at the bottom of the batching tank, so this kind of agitator will not be able to achieve the uniformity of the batching, which is directly related to the quality of the product
