DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0035] The waterproofing coiled material 30 is a material mainly used for waterproofing buildings. The waterproofing coiled material 30 is widely used in waterproofing projects of roofs, basements, toilets, bathrooms, kitchens, and various pools, sidewalks, tunnels, and other buildings. It can not only effectively prevent rainwater, groundwater, etc. from eroding buildings, but also increase the service life of buildings and reduce maintenance costs. The coating of the waterproofing coiled material 30 refers to covering the surface of the waterproofing coiled material 30 with a special film, which can be a plastic film, a metal film, a mineral film, etc. The main function of the coating is to protect the waterproofing coiled material 30 from the influence of the external environment, improve its weather resistance and aging resistance, and extend its service life. In the existing coating process of the waterproofing coiled material 30, the waterproofing coiled material 30 body and the coating are bonded together by hot pressing, and then immersed in water for cooling. After cooling, the coiled material is harvested for storage and transportation.

[0036] However, the method of cooling by soaking in water for a long time requires drying the water after cooling is completed, which is very time-consuming, and the water temperature in the pool will continue to rise, resulting in a longer cooling time. Therefore, in the existing waterproof membrane 30 coating process, the cooling method is very inefficient.

[0037] In order to solve the above problems, the object of the present invention is to provide an air-cooled waterproof coiled material coating cooling device, which is used for cooling the waterproof coiled material after coating; the air-cooled waterproof coiled material coating cooling device comprises a spraying device 10 for spraying a heat exchange medium on the surface of the waterproof coiled material 30 and a blasting assembly 20 for blowing air on the surface of the waterproof coiled material 30;

[0038] The cooling device is provided with an input port 31 for inputting the waterproof coiled material 30 and an output port 32 for outputting the waterproof coiled material 30. The waterproof coiled material 30 moves from the input port 31 to the output port 32 in the cooling device. The air blowing assembly 20 and the spraying device 10 are arranged in pairs. The waterproof assembly first passes through a spraying device 10 and then passes through an air blowing assembly 20. When the waterproof coiled material 30 passes through the spraying device 10, the heat exchange medium covers the surface of the waterproof coiled material 30. The blowing direction of the air blowing assembly 20 is opposite to the moving direction of the waterproof coiled material 30. The air blowing of the air blowing assembly 20 to the surface of the waterproof coiled material 30 can remove the heat exchange medium on the surface of the waterproof coiled material 30, so that the heat exchange medium evaporates and absorbs heat to cool the waterproof coiled material 30.

[0039] In this embodiment, Figure 1 , Figure 2 as well as Figure 3 As shown, the cooling device may be a long strip cabin, one end of the cabin is an input port 31, and the other end is an output port 32. The waterproof coiled material 30 enters the cabin from the input port 31 and leaves the cabin through the output port 32. In the working state, the waterproof coiled material 30 is continuously moving.

[0040] The cooling device may also be a cube surrounded by a box-type shell 41, and the waterproof coiled material 30 is folded back multiple times in the shell 41 to increase the length of the waterproof coiled material 30 in the shell 41 so that it has enough length to complete cooling.

[0041] In some embodiments, before the waterproof roll 30 is coated, the main body of the waterproof roll 30 and the coating are heated to a suitable temperature and then the main body of the waterproof roll 30 and the coating are bonded together. The input port 31 of the cooling device in this embodiment is the waterproof roll 30 that has not been cooled down after the main body of the waterproof roll 30 and the coating are bonded together, and the output port 32 outputs the waterproof roll 30 that has been cooled and dried, and can be rolled up for storage and transportation.

[0042] The heat exchange medium of this embodiment is water, and may also be other liquid heat exchange medium with large specific heat capacity. The spray device 10 is connected to a water source, and water is passed into the spray device 10 after being pressurized. The spray device 10 may include a main pipeline 11 and a plurality of nozzles 12 arranged along the length direction of the main pipeline 11. The main pipeline 11 is arranged along the width direction of the waterproof coiled material 30, and the nozzle 12 faces the waterproof coiled material 30. When the cooling device is working, the nozzle 12 continuously sprays water to the waterproof coiled material 30, and the waterproof coiled material 30 continuously moves. The movement of the waterproof coiled material 30 inside the cooling device can be achieved by a roller with a rotating power. The roller can be inside the cooling device or outside the cooling device, which is not shown in the figure.

[0043] By setting the number of nozzles 12 on the main pipe 11 and the range of water spraying by the nozzles 12, it can be achieved that the water sprayed by the multiple nozzles 12 on the main pipe 11 covers the entire area in the width direction of the waterproof coiled material 30. After the cooling medium is sprayed onto the waterproof coiled material 30, heat exchange can be performed, and the temperature of the cooling medium is much lower than the temperature of the waterproof coiled material 30. After the cooling medium is sprayed onto the surface of the waterproof coiled material 30, the waterproof coiled material 30 continues to move a certain distance, and the air blowing assembly 20 continues to spray airflow onto the surface of the waterproof coiled material 30. The airflow can blow away the moisture on the surface of the waterproof coiled material 30, and at the same time, it can also vaporize the moisture. An endothermic reaction occurs during vaporization, further reducing the temperature of the waterproof coiled material 30. The air blowing assembly 20 is connected to a blower or other device that can gather gas to generate airflow.

[0044] In some embodiments, the two surfaces with large surface areas of the waterproof membrane 30 are the upper surface and the lower surface respectively. The main pipe 11 and the nozzle 12 of the cooling device can spray water to the upper surface or the lower surface. Alternatively, only the main pipe 11 can be provided on both the upper surface and the lower surface to spray water to the upper surface and the lower surface respectively.

[0045] The nozzle 12 may be provided with an atomizing device, and water is attached to the surface of the waterproofing coiled material 30 in the form of aerosol, and the water sprayed to the lower surface will not drip downward or only a small amount of water will drip downward. A drain port is provided at the bottom of the housing 41 to discharge the dripping water.

[0046] Further, the air blowing assembly 20 includes an air supply duct 21 arranged on one side of the waterproof coiled material 30 in the width direction and a plurality of air outlet ducts 22 arranged on the air supply duct 21;

[0047] Of the two sides in the width direction of the waterproof membrane 30, the side close to the air supply duct 21 is the proximal end, and the other side is the distal end; the air outlet airflow composed of multiple air outlet ducts 22 is distributed in a fan shape, covering a partial area from the proximal end to the distal end of the waterproof membrane 30.

[0048] In this embodiment, Figure 3 , Figure 6 As shown, the air outlet duct 22 is arranged at the end of the air supply duct 21, and multiple air outlet ducts 22 are arranged at the end of the air supply duct 21. The axis of each air outlet duct 22 has a different angle with the axis of the air supply duct 21, so the airflow output by the multiple air outlet ducts 22 is fan-shaped. Figure 6 The schematic diagram of the airflow output by two air blowing assemblies 20 is shown. The bold dashed line in the figure is a schematic diagram of the fan-shaped airflow acting on the surface of the waterproof membrane 30.

[0049] The moisture at the proximal end of the waterproof membrane 30 first meets the airflow, and the airflow blows the moisture at the proximal end to the distal end. During the continuous movement of the waterproof membrane 30, the moisture at the proximal end gradually moves to the distal end, and finally the airflow of the waterproof membrane 30 is blown out from the distal end. A channel for collecting moisture can be set at the distal end to facilitate the centralized collection of moisture that has left the waterproof membrane 30.

[0050] Furthermore, the air-cooled waterproof membrane coating cooling device also includes a wind shield 33, which is arranged between the blowing assembly 20 and the spraying device 10. The wind shield 33 is used to block the airflow output by the blowing assembly 20 from interfering with the spraying device 10 to spray the heat exchange medium onto the surface of the waterproof membrane 30.

[0051] In this embodiment, Figure 3 , Figure 4 as well as Figure 6 As shown, the wind shield 33 is tilted and can guide the direction of the airflow on the side of the spray device 10 close to the blowing assembly 20 to change in the direction away from the waterproof membrane 30.

[0052] Furthermore, the waterproof coiled material 30 in the cooling device includes a plurality of sections, each of which is provided with a blast assembly 20 and a spray device 10;

[0053] The spraying device 10 is arranged on both sides of the waterproof roll material 30. The spraying devices 10 on both sides spray the heat exchange medium on the surface of the waterproof roll material 30 on both sides when the waterproof roll material 30 moves; the blowing assembly 20 is arranged on both sides of the waterproof roll material 30. The blowing assembly 20 blows air to both sides of the waterproof roll material 30 to remove the heat exchange medium on the surface of the waterproof roll material 30 and cool the waterproof roll material 30.

[0054] In this embodiment, the waterproof roll material 30 includes multiple segments, which means that the waterproof roll material 30 in the cooling device is divided into multiple sections according to the movement path of the waterproof roll material 30 in the cooling device. The waterproof roll material 30 passes through these sections in sequence when moving, and these waterproof roll materials 30 still remain a continuous whole without being cut.

[0055] The sections are respectively provided with a blast assembly 20 and a spray device 10. The spray device 10 is provided in front of the waterproof coiled material 30 entering the section, and the blast assembly 20 is provided at the rear of the section. After the waterproof coiled material 30 enters a section, the spray device 10 sprays the heat exchange medium on the surface of the waterproof coiled material 30. After moving a certain distance in the section, the blast assembly 20 sprays airflow to remove moisture to cool the waterproof coiled material 30. Then, the waterproof coiled material 30 enters the next section, and the above process is repeated until the cooling is completed.

[0056] In some embodiments, a blowing assembly 20 and a spraying device 10 are provided on both sides of the waterproofing membrane 30; the spraying devices 10 on both sides spray the heat exchange medium on the surface of both sides of the waterproofing membrane 30 when the waterproofing membrane 30 moves; the blowing assembly 20 blows air toward both sides of the waterproofing membrane 30 to remove the heat exchange medium on the surface of the waterproofing membrane 30 and to cool the waterproofing membrane 30.

[0057] In this embodiment, Figure 3 , Figure 4 as well as Figure 6 As shown, the air-cooled waterproof coiled material coating cooling device also includes a shell 41, which encloses a working space. The input port 31 and the output port 32 are respectively arranged on the shell 41. The waterproof coiled material 30 enters the working space through the input port 31 and exits the working space through the output port 32. The working space is used to complete the cooling of the fireproof coiled material.

[0058] The shell 41 may be a cube formed by splicing plate-shaped plastic or metal materials. The space enclosed by the shell 41 is a working space, which is used to cool down the fireproof coiled material.

[0059] Furthermore, a plurality of rollers 42 are provided in the working space, and the rollers 42 are connected to the housing 41 through bearings 43, and the rollers 42 can rotate freely, and the waterproofing coiled material 30 is guided by the rollers 42 and folded back multiple times to increase the length of the waterproofing coiled material 30 in the working space;

[0063] The waterproofing coiled material 30 is guided by the roller 42 and folded back multiple times, which means that the waterproofing coiled material 30 is guided by the roller 42 and folded back multiple times in the working space to increase the length of the waterproofing coiled material 30 in the working space; Figure 3 , Figure 6 As shown, in this embodiment, 6 rollers 42 are arranged in the working space, and the waterproof membrane 30 is folded back 4 times. The waterproof membrane 30 is input into the working space from the bottom left side in the direction shown in the figure, and is guided to be parallel to the length direction of the working space and to the right through the first roller 42.

[0070] In this embodiment, the recovery pipe 53 is used to recover the heat exchange medium. The temperature of the heat exchange medium sprayed by the spray device 10 is in a stable temperature range. The heat exchange medium recovered by the recovery pipe 53 can be cooled and then input into the spray device 10 again for recycling.

[0071] The guide groove 54 of this embodiment is arc-shaped and fixed on the shell 41. The guide groove 54 can be tilted. The heat exchange medium in the guide groove 54 flows downward under gravity and finally flows into the recovery pipe 53 outside the shell 41 through the guide channel 55.
