Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane cooling technology, specifically to a polymer waterproof membrane production and processing equipment. Background Technology

[0002] Waterproof membrane refers to a waterproof material product made by impregnating a base material with asphalt or polymer-based waterproofing materials. It is supplied in roll form and is called waterproof membrane. Waterproof membrane is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. It is a flexible building material that can be rolled up and serves as a leak-proof connection between the foundation and the building. It is the first line of defense for waterproofing the entire project and plays a vital role in the overall project.

[0003] In the current production process of polymer waterproof membranes, one of the processing steps is to immerse the hot-melted waterproof membrane in water for cooling. However, immersing the waterproof membrane in water can easily reduce its performance and affect the quality of the finished product. Utility Model Content

[0004] The purpose of this invention is to design a polymer waterproof membrane production and processing equipment that can solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A polymer waterproof membrane production and processing equipment includes a casing. Inside the casing, a first conveying roller, a second conveying roller, a third conveying roller, and a fourth conveying roller are rotatably connected in sequence along the conveying direction. A plurality of cooling rollers are rotatably connected between the second and third conveying rollers. The interior of each cooling roller has a hollow structure. The waterproof membrane conveyed between the third and fourth conveying rollers passes over the plurality of cooling rollers in an alternating manner. A chiller and a water pump are fixed on the top of the casing. The outlet of the water pump is connected to the inlet of the chiller. The inlet of the water pump is connected to one end of each cooling roller, and the outlet of the chiller is connected to the other end of each cooling roller.

[0007] Furthermore, a water storage tank is fixed to the side of the housing, the water outlet of the chiller is connected to the top of the water storage tank through a connecting pipe, and the bottom of the water storage tank is connected to the cooling roller.

[0008] Furthermore, the water pump's inlet end is connected to a water collection pipe via an inlet pipe, the bottom of the water storage tank is connected to a water supply pipe via a drain pipe, one end of the cooling roller passes through the housing and is connected to the water collection pipe via a first rotary joint, and the other end passes through the housing and is connected to the water supply pipe via a second rotary joint.

[0009] Furthermore, the outer surface of the water storage tank is provided with a cold insulation layer.

[0012] Furthermore, the cooling rollers are provided in five parts and are distributed sequentially along the horizontal direction.

[0013] The beneficial effects of this utility model are as follows:

[0014] By having the waterproof membrane alternately pass over several cooling rollers, the cold water inside the cooling rollers can absorb the heat from the waterproof membrane and heat it up, thereby cooling the waterproof membrane. The heated water is then pumped into a chiller to cool down, and the cooled water returns to the inside of the cooling rollers to continue cooling the waterproof membrane. This process avoids reducing the performance of the waterproof membrane, improves the quality of the finished product, and also saves water resources. Attached Figure Description

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] like Figure 1-3 As shown, a polymer waterproof membrane production and processing equipment includes a housing 1. Inside the housing 1, a first conveying roller 2, a second conveying roller 3, a third conveying roller 4, and a fourth conveying roller 5 are rotatably connected in sequence along the conveying direction. Several cooling rollers 6 are rotatably connected between the second conveying roller 3 and the third conveying roller 4. A power system inside the housing 1 drives the first conveying roller 2, the second conveying roller 3, the third conveying roller 4, the fourth conveying roller 5, and the cooling rollers 6 to rotate. Five cooling rollers 6 are arranged horizontally, and the number of cooling rollers 6 can be increased or decreased according to the cooling effect. The interior of each cooling roller 6... The structure is hollow. The waterproof membrane 19 conveyed between the third conveying roller 4 and the fourth conveying roller 5 alternately wraps around five cooling rollers 6, which can increase the contact area between the waterproof membrane 19 and the cooling rollers 6 and improve the cooling efficiency. The cooling rollers 6 are made of metal with good thermal conductivity, which can improve the heat transfer efficiency. A chiller 7 and a water pump 8 are fixed on the top of the casing 1. The outlet of the water pump 8 is connected to the inlet of the chiller 7. A water storage tank 9 is fixed on the side of the casing 1. The outlet of the chiller 7 is connected to the top of the water storage tank 9 through a connecting pipe 10. The water storage tank 9 stores the chilled water discharged by the chiller 7. The inlet of pump 8 is connected to a collecting pipe 12 via an inlet pipe 11. The bottom of the water storage tank 9 is connected to a supply pipe 14 via a drain pipe 13. A valve is installed at the drain pipe 13. One end of the cooling roller 6 passes through the housing 1 and is connected to the collecting pipe 12 via a first rotary joint 15. The other end passes through the housing 1 and is connected to the supply pipe 14 via a second rotary joint 16. After opening the valve on the drain pipe 13, the cold water in the water storage tank 9 flows into the supply pipe 14 through the drain pipe 13. The cold water is then distributed to the cooling roller 6. The cold water absorbs the heat from the waterproof membrane and heats it up, thereby cooling the waterproof membrane. The heated water flows into the water collection pipe 12, and the water pump 8 draws the water in the water collection pipe 12 into the chiller 7 for cooling. The cooled water then returns to the interior of the cooling roller 6 to continue cooling the waterproof membrane, thus avoiding a reduction in the performance of the waterproof membrane, improving the quality of the finished product, and saving water resources. The outer surface of the water storage tank 9 is provided with a cold insulation layer, which is made of polyurethane foam, to prevent heat conduction and improve the cold insulation effect of the water storage tank 9. The top of the water storage tank 9 is provided with a water inlet 17 for injecting water into the water storage tank 9, and the bottom of the water storage tank 9 is provided with a drain outlet 18 for draining the water in the water storage tank 9.

[0023] Working principle:

[0024] like Figure 1-3As shown, when the polymer waterproof membrane production and processing equipment is in use, the hot-melted waterproof membrane enters the machine casing 1 and is conveyed sequentially by the first conveying roller 2, the second conveying roller 3, five cooling rollers 6, the third conveying roller 4 and the fourth conveying roller 5, and then enters the next process for processing, wherein the waterproof membrane passes around the five cooling rollers 6 in an alternating manner.

[0025] As the waterproof membrane passes over the cooling roller 6, cold water in the water storage tank 9 flows into the water supply pipe 14 through the drain pipe 13. The cold water is then diverted to the cooling roller 6, where it absorbs heat from the waterproof membrane and heats up, thus cooling the membrane. The heated water then flows into the water collection pipe 12, where the water pump 8 draws the water into the chiller 7 for further cooling. The cooled water then returns to the cooling roller 6 to continue cooling the waterproof membrane, thus preventing a reduction in its performance, improving the quality of the finished product, and conserving water resources.
