Processing system of asphalt waterproof coiled material protective layer

Abstract

The invention discloses a processing system of an asphalt waterproof coiled material protective layer and belongs to the technical field of processing of asphalt waterproof coiled material protective layers. The processing system comprises a processing box, the left side and the right side of the processing box are both provided with through holes, and the inner side wall of the processing box is connected with a conveying mechanism used for conveying asphalt tire base cloth. In the continuous existing conveying process of the conveying mechanism, gravels are continuously and uniformly spread on the top of the tire base cloth on the basis of a sand coating mechanism, the number of the gravels in a sand coating box is controlled on the basis of a sand separating mechanism, and thus, it is guaranteed that no excessive gravels are added into the sand coating box at a time, the phenomenon that the uniformity of sand coating every time is difficult to control due to the fact that excessive gravels are accumulated in the sand coating box is avoided, the phenomenon that excessive gravels fall every time due to mutual extrusion of the excessive gravels is avoided, waste of the gravels is avoided, the gravels can be evenly and flatly laid on the top of the tire base cloth, and the processing and preparation of the asphalt waterproof coiled material protection layer can be facilitated.

Description

technical field [0001] The invention relates to the technical field of processing the protective layer of asphalt waterproof coiled material, in particular to a processing system for the protective layer of asphalt waterproof coiled material. Background technique [0002] Waterproof membranes are mainly used in roofing and underground waterproofing projects of industrial and civil buildings, tunnels, railways, bridges and other public works to prevent external water from penetrating into buildings or eroding building structures. Usually, modified asphalt waterproof membranes, synthetic polymer waterproof membranes or coatings are commonly used. The production process of waterproof membrane generally includes the following steps: lapping and drying of the base fabric, prepreg and coating of the base fabric, sanding or film coating, cooling and winding. Among them, only after sanding or film coating is applied to the oiled cloth after coating treatment and a protective layer ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a processing system for the protective layer of asphalt waterproof coiled material, to solve the problem in the above background technology that in the prior art, in the process of applying sand to the asphalt coiled material to produce the protective layer, manual application is often used. sand, the efficiency of sand application is low, and the uniformity of sand application is difficult to ensure, which will not only lead to poor preparation of the protective layer, but also lead to a large amount of waste of fine sand, and the existing spreading mechanism will not be used when spreading gravel. There is a large amount of gravel stored on the top, which not only easily leads to blockage of the spreading mechanism, but also makes the gravel falling inconsistent each time, which affects the preparation of the protective layer
