Description

Technical Field

[0001] This utility model relates to a cooling and drying device, and more particularly to a cooling and drying device for the production of waterproof membrane rolls. Background Technology

[0002] Asphalt waterproof membrane refers to roll materials made of asphalt, a reinforcing material, and a surface-applied anti-adhesion material, also known as roofing felt. It is commonly used for adhesive waterproofing layers. Asphalt waterproof membranes are categorized into reinforced and unreinforced rolls. Reinforced rolls are those made by impregnating petroleum asphalt with a reinforcing material such as thick paper, fiberglass cloth, asbestos cloth, or cotton / linen fabrics. During processing, asphalt is impregnated onto the reinforcing fabric surface, and a film is applied to the asphalt surface. This process results in a high temperature for the membrane, necessitating cooling and drying. Currently, natural air cooling and water cooling are commonly used. Air cooling takes longer, affecting processing efficiency and working space, while water cooling leaves a large amount of moisture on the membrane surface, resulting in a longer drying time. Utility Model Content

[0003] The purpose of this invention is to provide a cooling and drying device for the production of waterproof membranes. It can improve the cooling and drying effect of waterproof membranes and increase processing efficiency.

[0004] The technical solution of this utility model is as follows: A cooling and drying device for the production of waterproof roll material includes a frame. The upper part of the frame is provided with multiple sets of cooling cylinders arranged vertically and horizontally in a staggered manner. Cooling water is provided in the cooling cylinders. Water inlet pipes and water outlet pipes corresponding to the cooling cylinders are provided at both ends of the cooling cylinders. A water spraying assembly for spraying water to cool the cooling cylinders is provided on one side of the cooling cylinders. A drying chamber is provided at the rear side of the cooling cylinders. A feed inlet and a discharge outlet are provided at the front and rear ends of the drying chamber, respectively. An air curtain machine is provided in the feed inlet and the discharge outlet. Multiple sets of reversing rollers are arranged vertically and horizontally in a staggered manner in the drying chamber. A wiping mechanism is provided between the reversing rollers at the front end, and nozzles are evenly distributed between the reversing rollers at the rear end.

[0006] In the aforementioned cooling and drying device for the production of waterproof membrane, the angle between the direction of the air curtain machine at the feed inlet and the direction of movement of the membrane is less than 90 degrees, and the air curtain machine is set tilted downwards.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] Example. A cooling and drying apparatus for the production of waterproof membranes, configured as follows: Figure 1-2As shown, the machine includes a frame 1. The upper part of the frame 1 is provided with multiple sets of cooling cylinders 2 arranged vertically and horizontally. Cooling water is provided in the cooling cylinders 2. The two ends of the cooling cylinders 2 are provided with water inlet pipes 3 and water outlet pipes 4 corresponding to the cooling cylinders 2. A water spraying assembly is provided on one side of the cooling cylinders 2 to spray water to cool them down. A drying chamber 5 is provided at the rear side of the cooling cylinders 2. The front and rear ends of the drying chamber 5 are respectively provided with a feed inlet 6 and a discharge outlet 7. An air curtain machine 19 is provided in the feed inlet 6 and the discharge outlet 7. Multiple sets of reversing rollers 8 are arranged vertically and horizontally and horizontally. A wiping mechanism is provided between the reversing rollers 8 at the front end, and nozzles 9 are evenly distributed between the reversing rollers 8 at the rear end.

[0017] The cooling cylinder 2 includes a rotating shaft 201, a cylinder body 202 outside the rotating shaft 201, and multiple sets of connecting plates 203 connected to the rotating shaft 201 inside the cylinder body 202. The contact surfaces of the connecting plates 203 and the cylinder body 202 are provided with evenly distributed arc-shaped holes 204, and the arc-shaped holes 204 of adjacent connecting plates 203 are staggered. The cylinder body 202 is provided with annular baffles 205 at both ends, and a branch pipe 206 connected to the water inlet main pipe 3 and the water outlet main pipe 4 is provided between the annular baffles 205 and the rotating shaft 201.

[0018] The angle between the direction of the air curtain machine 19 at the six feed inlets and the direction of roll material movement is less than 90 degrees, and the air curtain machine 19 is set tilted downwards.

[0019] The wiping mechanism includes mounting bases 13 fixedly connected to the inner walls of both sides of the drying chamber 5, mounting rods 14 respectively disposed on both sides of the roll material between the mounting bases 13, and water-absorbing sleeves 15 disposed outside the mounting rods 14.

[0020] The mounting base 13 is provided with a squeezing plate 16 corresponding to the water-absorbing sleeve 15. The squeezing plate 16 has a V-shaped cross-section and the opening direction is upward.

[0021] The water spray assembly includes a water supply pipe 17 arranged in the same direction as the cooling cylinder 2, and a nozzle 18 is provided on the water supply pipe 17.

[0022] The principle of this invention is as follows: The waterproof membrane first passes through a cooling cylinder 2, which contains cooling water to cool the membrane. A water spray assembly further enhances the cooling effect by spraying water onto the membrane. The end of the water supply pipe 17 is connected to the main water inlet pipe 3. Because the water temperature inside the cooling cylinder 2 rises during contact with the waterproof membrane, affecting the cooling effect, this application provides a main water inlet pipe 3 and a main water outlet pipe 4 on both sides of the cooling cylinder 2 to replace the water in the cooling cylinder 2 in real time. Since the cooling cylinder rotates, connection is inconvenient. Therefore, in the prior art, a hollow rotating shaft 201 is usually used, with rotary joints at both ends of the shaft 201 for replacing the water in the cooling cylinder 2. However, this reduces the strength of the rotating shaft and poses a certain safety hazard. Therefore, this application provides annular baffles 205 at both ends of the cylinder 202, allowing a portion of water to be stored between the annular baffles 205 and the connecting plates 203. Furthermore, the connecting plates 203 have arc-shaped holes 204 on their contact surfaces with the cylinder 202. When water is drawn from the outlet manifold 4 and supplied to the cooling cylinder 2 from the inlet manifold 3, the water can move through the connecting plates 203 towards the outlet manifold 4, enabling real-time replacement of the cooling water. Cooling can also be achieved through an external cooling pool. The cooling cylinder 2 structure of this application not only eliminates the need for a hollow rotating shaft 201, but also provides multiple sets of connecting plates 203 between the cylinder 202 and the rotating shaft 201, providing better support for the cylinder 202 and resulting in greater strength.

[0023] After cooling, the waterproof membrane enters the drying chamber 5 for drying. During this process, the membrane is conveyed at an upward angle. Since a film adheres to the surface of the membrane, the air curtain 19 effectively blows away most of the moisture, preventing excessive humidity within the drying chamber 5 and hindering moisture evaporation. Next, the membrane is wiped by a wiping mechanism to further remove moisture. As the mounting rod 14 rotates, the absorbent sleeve 15 contacts the membrane surface, removing moisture. A squeezing plate 16 on one side of the absorbent sleeve 15 works in conjunction with it to squeeze out some of the moisture. A flow channel is formed at the top of the squeezing plate 16 to transport water outside the drying chamber 5. Finally, the membrane is dried by the nozzles 9, resulting in a faster and more effective drying process.
