Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of asphalt waterproofing membrane processing, in particular to an asphalt waterproofing membrane processing equipment and method for building construction. BACKGROUND

[0002] Asphalt waterproofing membrane is a rolled material made of asphalt material, base material and surface-sprayed anti-sticking material, commonly known as oil felt. Asphalt waterproofing membrane can be divided into two types: with base and without base. The former is made by impregnating petroleum asphalt into thick paper, glass fiber cloth, asbestos cloth, cotton and linen fabric, etc., while the latter is made by adding asbestos and rubber powder to asphalt material and then rolling.

[0003] The processing equipment of asphalt waterproofing membrane mainly includes several links such as raw material pretreatment, base cloth impregnation, scraping and thickness control, film covering and exhaust, cooling and shaping, and cutting and packaging. Among them, film covering and exhaust and cooling and shaping are crucial parts in the whole production process, usually by immersing the laminated film and modified asphalt layer into water or through other cooling devices for cooling.

[0004] Chinese patent discloses application number 202221195383.9 "cooling device for waterproofing membrane" including a rack and multiple water-cooled rollers, the water-cooled rollers are arranged in multiple layers, each layer includes N water-cooled rollers arranged side by side in front and back, and water supply main pipes and water collecting pipes on the left and right sides; the water-cooled roller includes a shaft, a cylinder and multiple support plates, the both ends of the shaft are rotatably arranged on the rack; the inner wall of the left end of the cylinder is provided with an annular sealing plate, and the right end is a neck-in structure; the sealing plate and the shaft have an annular gap between them, the water supply main pipes and the water collecting pipes are arranged on the rack along the front and back direction, the water supply main pipes are provided with N water supply branch pipes, the inner ends of the water supply branch pipes pass through the gap to the space between the sealing plate and the leftmost support plate; the right side of the neck-in structure forms an annular end face coaxial with the cylinder, the upper side of the water collecting pipe is provided with N notches, and the lower part of the annular end face extends into the notches; the water of all water collecting pipes is collected together; multiple hollow holes through which water flows are arranged on the support plates around the shaft.

[0005] Although this device can cool, due to the different shrinkage rates of the film and the modified asphalt layer, their cooling shrinkage speeds do not match, which easily leads to peeling between them. In addition, the edges of the film may be raised, affecting its wrapping property. During subsequent transportation and storage, the modified asphalt layer may be exposed, and then contaminated or worn. SUMMARY

[0006] The purpose of the present application is to provide an asphalt waterproofing membrane processing equipment and method for building construction, which solves the problem of peeling and film edge lifting during film covering and modified asphalt layer laminating and cooling in the existing equipment, thereby affecting the wrapping property.

[0031] The wrapping mechanism comprises a plurality of water spraying pipes 14 communicated with the cooling roller 7, and the water spraying pipes 14 are bent downward by 45 degrees on both sides and annularly surround the outside of the film 3; when the film 3 shrinks, the excess reserved edge 301 of the film 3 is tightly wrapped around the edge of the modified asphalt layer 2 under the guidance of the water flow.

[0032] Further, as shown in the Figure 1 water pump 9 is communicated with the second pipeline 8 on one side, the second pipeline 8 is communicated with the cooling roller 7; when the water pump 9 works, the water in the cooling box 1 is transported into the cooling roller 7 through the second pipeline 8.

[0033] Further, as shown in the Figure 1 the cooling roller 7 and the extrusion roller 5 are symmetrically rotatably installed on both ends of the fixed plate 6, and the fixed plate 6 is fixedly installed on the cooling box 1; the fixed plate 6 supports the extrusion roller 5 and the cooling roller 7.

[0034] Further, as shown in the Figure 5 the cooling roller 7 is internally installed with a spiral blade 16; when the cooling roller 7 rotates, the spiral blade 16 rotates to accelerate the water flow from the cooling roller 7, so that the cooling roller 7 and the modified asphalt layer 2 can always maintain a large temperature difference and timely remove heat.

[0035] Further, as shown in the Figure 2 the support plate 11 is fixedly installed on the upper end surface of the water spraying pipe 14 and fixedly installed on the cooling box 1 on both ends; the support plate 11 supports the water spraying pipe 14.

[0036] Further, as shown in the Figure 3 a plurality of water spraying heads 15 are installed on the side of the water spraying pipe 14 facing the film 3; the water spraying heads 15 cool the film 3 and make the reserved edge 301 bend downward.

[0037] Further, as shown in the Figure 1 the third pipeline 12 is communicated with the first pipeline 4 away from the water spraying pipe 14 on one side, and the first pipeline 4 is communicated with the cooling roller 7 away from the third pipeline 12 on the other side; the water in the cooling roller 7 enters the water spraying pipe 14 through the first pipeline 4 and the third pipeline 12.

[0038] Further, as shown in the Figure 1As shown, the inner wall of the cooling box 1 is respectively rotatably installed with a first round rod 10 and a second round rod 13; the first round rod 10 and the second round rod 13 change the movement trajectory of the modified asphalt layer 2 and the film 3.

[0039] In this embodiment, as shown in the figure, Figure 4 As shown, when the film 3 passes through the water spraying head 15, the reserved edge 301 will show a bending trend from horizontal to downward, at this time, the film 3 shrinks, and the reserved edge 301 will wrap the outer wall of the modified asphalt layer 2 and will not be raised.

[0040] In this embodiment, the asphalt waterproof coiled material processing method for building construction comprises the following steps:

[0041] First step: when the film 3 and the modified asphalt layer 2 are conveyed between the extrusion roller 5 and the cooling roller 7, at this time, the extrusion roller 5 and the cooling roller 7 perform lamination on them, at the same time, the water pump 9 works, and the water in the cooling box 1 is extracted through the second pipeline 8 into the cooling roller 7, since the cooling roller 7 is internally installed with a spiral blade 16, at this time, the spiral blade 16 rotates with the cooling roller 7, and the spiral blade 16 will accelerate the flow of water, so as to better cool the modified asphalt layer 2, thereby reducing the temperature gradient of the film 3 and the modified asphalt layer 2;

[0042] Second step: as the film 3 and the modified asphalt layer 2 advance, they will be changed in path by the first round rod 10, at this time, the modified asphalt layer 2 abuts against the water in the cooling box 1, at the same time, the water in the cooling roller 7 enters the water spraying pipe 14 through the first pipeline 4 and the third pipeline 12, and the water in the water spraying pipe 14 is sprayed out through the water spraying head 15, at this time, the water spraying head 15 parallel to the film 3 cools and lowers the temperature of the film 3, and the water spraying head 15 arranged at 45 degrees on both sides of the water spraying pipe 14 will make the reserved edge 301 bend downward, at this time, the film 3 and the modified asphalt layer 2 shrink due to cooling, since the water in the water spraying pipe 14 flows in through the cooling roller 7, the temperature is different from the water temperature in the cooling box 1, so the shrinkage speed difference between the film 3 and the modified asphalt layer 2 is reduced, when the film 3 and the modified asphalt layer 2 pass through the second round rod 13, at this time, the lamination and cooling of the film 3 and the modified asphalt layer 2 are completed, the reserved edge 301 of the film 3 will not be raised upward, but will be attached to the outer wall of the modified asphalt layer 2, thereby protecting the modified asphalt layer 2 from being polluted or abraded.
