Description

Horizontal batching machine for production of modified asphalt waterproof membrane base material

technical field

The utility model belongs to the field of equipment for preparing waterproof materials, in particular to a horizontal batching machine for preparing base materials of modified asphalt waterproof coiled materials.

Background technique

At present, the production of modified asphalt waterproofing membranes is divided into two parts, specifically the asphalt modification process and the membrane forming process. After heating up the asphalt to a certain temperature, add modified materials, fillers and other materials for stirring and 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.

Therefore, the batching machine plays a very important role in the effect of modified asphalt. A batching machine with a reasonable structural design can improve the modification effect to a certain extent under the same process formula, and can shorten the modification time and improve production efficiency. However, in the preparation of modified asphalt waterproofing membranes, the batching machines used are basically vertical, which has the following disadvantages:

1) For the vertical batching machine, 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;

2) For the vertical batching machine, the stirring shaft is also set vertically, and most of the stirring paddles are set horizontally or spirally wound. Specifically, the rotation of the stirring 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 stirring paddle will not be able to achieve the uniformity of the batching, which is directly related to the quality of the product.

However, in response to the above technical deficiencies, the applicant provided a patent on 2013-12-30 "A batching device for preparing modified asphalt waterproof membrane" (patent number: ZL201320881879.6), which also involves a horizontal type batching device, and include a batching tank with a feed inlet and a feed outlet, a stirring device, wherein the stirring device includes a drive motor, a stirring shaft driven by the driving motor, a stirring paddle arranged on the stirring shaft, particularly, The batching tank is extended along the horizontal direction, the stirring shaft is arranged in the batching tank along the extending direction of the batching tank, and the stirring paddle includes a plurality of helical ribbons wound on the stirring shaft in a helical shape along the extending direction of the stirring shaft.

Although the horizontal batching device can effectively reduce the unevenness of the batching caused by the sedimentation of the batching, it can also make full use of the batching tank to improve the batching efficiency and ensure the batching quality.

However, it has an obvious defect: since the stirring shaft is connected through the bearing seat outside the batching tank, the material is easy to leak from the gap between the stirring shaft and the bearing seat, the leaked material is easy to pollute the working environment, and there is also a hidden danger of scalding accidents.
