Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, specifically to a cooling device for waterproof membranes. Background Technology

[0002] Waterproof membrane is a sheet-like waterproof material made from synthetic polymer materials, asphalt, or polymer-modified asphalt as base materials, with the addition of additives and reinforcing materials. It is widely used in building roofs, underground engineering, and water conservancy projects to prevent water penetration. Its performance requirements include good flexibility, weather resistance, tensile strength, and waterproof sealing. The cooling process during production is one of the key steps to ensure the performance of the membrane. During the production of waterproof membrane, the high-temperature molten modified asphalt, polymer materials, and other raw materials are extruded or calendered, and then quickly solidified and shaped using a cooling device to prevent deformation, adhesion, or performance degradation of the membrane due to excessively high temperatures.

[0003] Existing technology uses a straight-line water tank for cooling. After the high-temperature roll material enters the tank, it comes into direct contact with the cooling water. Heat is transferred from the roll surface to the water layer via thermal conduction. The water in the tank circulates, carrying away the high-temperature water from the roll surface while simultaneously replenishing with cooler water. Forced convection enhances heat dissipation efficiency. The coordination of the water flow speed and direction with the roll material's movement accelerates heat exchange. However, existing straight-line water tank cooling methods result in a single, unchanging cooling path, leading to a very large footprint and demanding site requirements. Utility Model Content

[0004] In order to solve the technical problem that the existing straight water tank roll cooling path is single and unchanging, resulting in a very large water tank area and high site requirements, this utility model provides a cooling device for waterproof rolls.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for waterproof membrane, comprising: a U-shaped water tank, the U-shaped water tank being divided into two vertical sections and a bent section, a rotating shaft being rotatably connected to the side wall of the U-shaped water tank of the bent section and one vertical section, the membrane being immersed in the upper part of the other vertical section, a guide roller being connected to the rotating shaft inside the U-shaped water tank, multiple guide rollers being arranged in two sets of J-shaped structures, the two sets of J-shaped structures contacting the inner U-side and outer U-side of the inner wall of the U-shaped water tank respectively, the guide rollers of the two sets of J-shaped structures rotating in opposite directions to transport the membrane, a guide gap being left between the guide rollers of the two sets of J-shaped structures, the width of the guide gap being equal to the thickness of the membrane, and the U-shaped water tank being connected to a cold water injection and discharge mechanism.

[0006] Preferably, adjacent shafts of the same J-type structure are connected by belt drive, and one shaft of the same J-type structure is connected to the power output shaft.

[0007] Preferably, the inner wall of the vertical section of the U-shaped water tank without guide rollers is connected to two guide plates, which can guide the roll material into the guide gap.

[0008] Preferably, the cold water injection and drainage mechanism includes an injection pipe, which is connected to the bend section of the U-shaped water tank and a cold water pump. The upper part of the two vertical sections of the U-shaped water tank is connected to a drain pipe, and the middle part of the drain pipe is connected to a drain pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. Under the action of thermal convection, the water temperature in the U-shaped water tank changes in a gradient. The roll material enters the water through the vertical section on one side of the U-shaped water tank and is cooled gradually to avoid sudden cooling that would cause a decrease in quality. After the outer layer is cooled and shaped, it enters the guide gap and is guided out by two sets of J-shaped guide rollers. During the process, the inner layer is also cooled. The clamping of the guide rollers also prevents cooling wrinkles and deformation. Compared with a straight water tank, it saves a lot of space while having a better cooling effect.

[0011] 2. The cold water injection and drainage mechanism has water injected at the bottom and drained at the top, which better maintains the water temperature gradient in the U-shaped water tank and further avoids sudden cooling from affecting the quality of the roll material.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] The following is in conjunction with the appendix Figure 1-2 This embodiment describes a cooling device for a waterproof membrane, comprising: a U-shaped water tank 1, which is divided into two vertical sections and one bent section. A rotating shaft 2 is rotatably connected to the side wall of the U-shaped water tank 1 of the bent section and one vertical section. The membrane is immersed in the upper part of the other vertical section. A guide roller 3 is connected to the rotating shaft 2 inside the U-shaped water tank 1. The multiple guide rollers 3 are arranged in two sets of J-shaped structures. The two sets of J-shaped structures are in contact with the inner U-side and outer U-side of the inner wall of the U-shaped water tank 1, respectively. The guide rollers 3 of the two sets of J-shaped structures rotate in opposite directions to transport the membrane. A guide gap 5 is left between the two sets of J-shaped structure guide rollers 3. The width of the guide gap 5 is equal to the thickness of the membrane. The U-shaped water tank 1 is connected to a cold water injection and discharge mechanism 6.

[0019] Under the action of thermal convection, the water temperature in the U-shaped water tank 1 changes in a gradient. Hot water rises to the upper part of the vertical section, while cold water sinks to the bending section. The roll material enters the water through the vertical section on one side of the U-shaped water tank 1 and is cooled gradually to avoid sudden cooling that would cause a decrease in quality. After the outer layer is cooled and shaped, it enters the guide gap 5. Since the two sets of J-shaped guide rollers 3 rotate in opposite directions, they transport the roll material. The roll material is guided by the two sets of J-shaped guide rollers 3 to the upper part of the vertical section and discharged. During the process, the inner layer is also cooled. The clamping of the guide rollers 3 also avoids cooling wrinkles and deformation. Compared with a straight water tank, it saves a lot of space for the same cooling length while having a better cooling effect.

[0020] Adjacent shafts 2 of the same group of J-type structures are connected by belt drive 7, and one shaft 2 of the same group of J-type structures is connected to the output shaft of the power.

[0021] Power is transmitted via belt drive to ensure that the J-type structures in the same group operate at the same speed and in the same direction.

[0022] The vertical section of the U-shaped water tank 1 without guide rollers 3 is connected to two guide plates 8, which can guide the roll material into the guide gap 5.

[0023] To prevent the roll material from failing to enter the guide gap 5 in time and being folded within the vertical section.

[0024] The cold water injection and drainage mechanism 6 includes an injection pipe 61, which is connected to the bend section of the U-shaped water tank 1 and to a cold water pump. The upper part of the two vertical sections of the U-shaped water tank 1 is connected to a drain pipe 62, and the middle part of the drain pipe 62 is connected to a drain pipe 63.

[0025] Cold water is injected into the bent section of the U-shaped water tank 1 through the water injection pipe 61, and hot water rises to the upper part of the vertical section of the U-shaped water tank 1 and is discharged through the drain pipe 62 and drain pipe 63, which better maintains the water temperature gradient in the U-shaped water tank 1 and further avoids sudden cooling from affecting the quality of the roll material.
