Description

Technical Field

[0001] This invention relates to the field of asphalt waterproof membrane processing technology, and in particular to an anti-drip device for an asphalt waterproof membrane impregnation tank. Background Technology

[0002] Asphalt waterproof membrane is a sheet-like waterproof product made of asphalt or polymer-modified asphalt as the main waterproof material and polyester felt, fiberglass felt, etc. as the reinforcing base. It is formed by impregnation and coating and then covered with a release material on both sides. It is mainly used in roofing, underground, bridge and tunnel and water conservancy projects. Its core advantages are low production cost and high cost performance. It is one of the most widely used and technologically mature materials in modern building waterproofing systems. At present, in the production process of asphalt waterproof membrane, the base is usually coated with asphalt in an impregnation tank.

[0003] Currently, in the production process of asphalt waterproof membrane, an immersion coating tank is typically used to coat the substrate with asphalt. Existing immersion coating tank equipment generally includes a tank body, a heating system, and a guide roller assembly. During production, the substrate is immersed in liquid asphalt under the guidance of the immersion rollers, and after being coated, it is pulled away from the tank by the guide roller assembly. However, after the membrane leaves the asphalt surface, its surface, especially the lower surface and the two side edges, will absorb a large amount of excess molten asphalt. During the traction process of the guide roller assembly, this part of the asphalt continuously accumulates under the action of gravity, forming "edge drips" or "teardrops," which drip onto the equipment base or workshop floor. This not only wastes materials, but the hard asphalt clumps formed after cooling are also difficult to clean, increasing the labor maintenance costs. Therefore, there is an urgent need to develop an anti-drip device for asphalt waterproof membrane immersion coating tanks that can effectively prevent asphalt dripping, maintain workshop cleanliness, and improve material utilization.

[0013] An asphalt inlet pipe is connected to one side of the inner cavity of the immersion tank, and an asphalt outlet pipe is connected to the bottom of the inner cavity of the immersion tank, with a drain valve installed on the asphalt outlet pipe.

[0014] As a further description of the above technical solution:

[0015] A temperature sensor is fixedly installed on the inner wall of the dip coating tank.

[0016] As a further description of the above technical solution:

[0017] A control panel is fixedly installed on the side wall of the immersion tank, and the control panel is electrically connected to the electric push rod, the heating fan and the temperature sensor.

[0018] As a further description of the above technical solution:

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention, by setting up an inlet roller, an outlet roller, and a safety gate, and cooperating with an electric push rod to drive the lifting plate and the immersion pressure roller, enables the waterproof membrane base to achieve a stable downward immersion path in the immersion tank. The structure is reasonably designed and easy to operate. It not only ensures the continuous and stable input and output of the base under the drive of the traction mechanism, but also facilitates the threading operation before start-up and daily maintenance through the design of the safety gate, significantly improving the ease of use and continuous operation capability of the equipment.

[0026] 2. This invention achieves precise and uniform control of asphalt liquid temperature by incorporating a heating chamber built into the side wall of the immersion tank and connecting it to a heat transfer oil circulation system, in conjunction with a temperature sensor. This avoids the problems of asphalt thickening, poor fluidity, and subsequent material removal difficulties caused by excessively low temperatures, and also prevents asphalt solidification and blockage caused by cooling during shutdown. At the same time, the asphalt discharge pipe can quickly remove excess material when the machine is stopped, effectively ensuring the stability of asphalt coating quality and extending the service life of the equipment.

[0027] 3. This invention, by setting up an anti-drip box with air knife nozzles and using a heating fan to provide high-temperature and high-pressure hot air, forms an effective air curtain barrier on the vertical discharge path. This can flatten and thin the excess asphalt on the surface of the roll material and form a uniform liquid film. Gravity is used to allow the peeled asphalt particles to flow directly back into the impregnation tank for automatic recycling. This not only solves the problem of asphalt dripping polluting the workshop environment from the source, but also significantly reduces the waste of asphalt materials and lowers production costs.

Detailed Implementation

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] In the description of the invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; furthermore, unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, they can be fixed connections, detachable connections, or integral connections; they can be mechanical connections or electrical connections; they can be direct connections or indirect connections through an intermediate medium; they can be internal connections between two elements. For those skilled in the art, the specific meaning of the above terms in the invention can be understood according to the specific circumstances:

[0042] Please refer to Figures 1 to 9 As shown, an anti-drip device for an asphalt waterproof membrane impregnation tank includes an impregnation tank 3, an immersion roller 27, and an anti-drip box 11. An electric push rod 9 is bolted to the center of the top surface of the impregnation tank 3, and a lifting plate 25 is fixedly connected to the output end of the electric push rod 9. Mounting shafts 26 are symmetrically fixed to both ends of the lifting plate 25, and the immersion roller 27 is mounted on the mounting shafts 26. A square tube 5 for entering the base is connected to one side of the top surface of the impregnation tank 3, and a third fixing frame 12 is welded to the other side of the top surface of the impregnation tank 3. A connecting... The anti-drip box 11 is located inside the immersion tank 3. An air distribution box 31 is fixedly installed inside the anti-drip box 11. Several sets of mounting seats 33 are symmetrically installed on the inner wall of the air distribution box 31. An air knife nozzle 34 is fixedly installed on the mounting seat 33. An mounting base 20 is bolted to the side wall of the anti-drip box 11. A heating fan 21 is fixedly installed on the mounting base 20. An air inlet pipe 22 is connected to the input end of the heating fan 21. An air outlet pipe 30 is connected to the output end of the heating fan 21. The other end of the air outlet pipe 30 is connected to the inner cavity of the air distribution box 31.

[0043] The top center of the immersion tank 3 is driven by an electric push rod 9 to lift the plate 25 and the immersion rollers 27 mounted on the shaft brackets 26 at both ends. This, together with the tire base square tube 5, achieves stable downward pressure and immersion of the tire base. On the other side of the top surface, a third fixing bracket 12 is welded to connect to the anti-drip box 11. The anti-drip box 11 has an air equalization box 31 and an air knife nozzle 34 fixed by the mounting base 33. The heating fan 21 on the side wall mounting base 20 is connected to the air equalization box 31 through the air inlet pipe 22 and the air outlet pipe 30. The whole structure forms an integrated and compact structure from the forced immersion of the immersion roller 27 to the surface treatment of the hot air knife nozzle 34 in the anti-drip box 11. This ensures that the tire base is immediately subjected to high temperature and high pressure purging in the vertical direction after continuous immersion, effectively preventing dripping and promoting asphalt return circulation.

[0044] Please refer to Figure 3 As shown, a heating chamber 28 is provided inside the side wall of the immersion tank 3, and a heat transfer oil inlet pipe 23 is connected to one side of the bottom of the heating chamber 28, and a heat transfer oil outlet pipe 24 is connected to one side of the top of the bottom of the heating chamber 28.

[0045] The heating chamber 28 inside the side wall of the immersion tank 3 forms a circulating heating channel through the heat transfer oil inlet pipe 23 connected to the bottom side and the heat transfer oil outlet pipe 24 connected to the top side. This allows the heat energy provided by the external heat transfer oil circulating heating equipment to be evenly transferred to the inner cavity of the immersion tank 3, achieving heat preservation and heating of the asphalt liquid. In conjunction with the temperature sensor 29 fixedly installed in the inner cavity of the immersion tank 3 to monitor temperature changes, the viscosity and surface tension of the asphalt are kept stable. This avoids the problems of asphalt thickening and poor fluidity caused by excessively low temperature, as well as the inability of the subsequent anti-drip mechanism to effectively remove excess asphalt material. It also prevents the decline in product processing quality caused by temperature fluctuations, significantly improving the uniformity and processing stability of asphalt immersion coating.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, a first fixing frame 6 is bolted to one side wall of the immersion tank 3, and an inlet roller 7 is installed on the first fixing frame 6. A second fixing frame 13 is bolted to the other side wall of the immersion tank 3, and an outlet roller 10 is installed on the second fixing frame 13.

[0047] The first fixing frame 6 and its guide roller 7, which are bolted to one side wall of the immersion tank 3, together with the second fixing frame 13 and its guide roller 10, which are bolted to the other side wall, together form a stable base material inlet and outlet guide structure. This ensures that the waterproof membrane base material smoothly enters and exits the inner cavity of the immersion tank 3 along a preset path under continuous traction. With the layout of the base material inlet square tube 5 and the anti-drip box 11, the base material can pass around the guide roller 7 and the immersion pressure roller 27 in sequence before being introduced into the anti-drip box 11 and finally exited around the guide roller 10. This realizes a continuous operation from feeding to immersion coating to anti-drip treatment, which is simple to operate and runs stably.

[0048] Please refer to Figure 5 and Figure 8 As shown, the top surface of the lifting plate 25 is symmetrically welded with guide slide rods 8, and the top surface of the immersion tank 3 is symmetrically fixedly installed with guide slide sleeves 32, and the guide slide rods 8 are sleeved inside the guide slide sleeves 32.

[0049] The guide slide rod 8, which is symmetrically welded to the top surface of the lifting plate 25, and the guide slide sleeve 32, which is symmetrically fixedly installed on the top surface of the immersion tank 3, are interlocked. This provides precise vertical guidance constraint for the electric push rod 9 to drive the lifting plate 25 to move up and down, effectively preventing the lifting plate 25 from tilting or shaking during the lifting process. This ensures that the immersion roller 27 on the mounting bracket 26 can smoothly and vertically press the tire base into the asphalt liquid below the surface, thereby ensuring that the immersion depth and position of the tire base in the immersion tank 3 remain constant, significantly improving the uniformity of immersion and the stability of operation.

[0050] Please refer to Figure 5 As shown, an asphalt inlet pipe 4 is connected to one side of the inner cavity of the immersion tank 3, and an asphalt outlet pipe 17 is connected to the bottom of the inner cavity of the immersion tank 3, with a drain valve 16 installed on the asphalt outlet pipe 17.

[0051] The asphalt inlet pipe 4 connected to one side of the inner cavity of the immersion tank 3 is used to introduce the heated asphalt liquid into the tank for immersion coating. The asphalt outlet pipe 17 connected to the bottom of the inner cavity and the drain valve 16 installed on it facilitate the timely discharge of unused asphalt liquid after the equipment is shut down, preventing the asphalt from cooling and solidifying in the inner cavity of the immersion tank 3 and affecting the next use of the device. This realizes convenient input and discharge control of asphalt liquid, reduces maintenance difficulty and extends the service life of the equipment.

[0052] Please refer to Figure 5 As shown, a temperature sensor 29 is fixedly installed on the inner wall of the immersion tank 3.

[0053] The temperature sensor 29, which is fixedly installed on the inner wall of the dipping tank 3, can monitor the temperature change of the asphalt liquid in real time. Together with the heat transfer oil circulation heating system of the heating chamber 28, it forms a closed-loop temperature control, ensuring that the viscosity and surface tension of the asphalt are stable within the optimal process range. This avoids the problems of the asphalt thickening and poor fluidity caused by excessively low temperature, as well as the inability of the subsequent anti-drip mechanism to effectively remove excess asphalt material. It also ensures the quality of the asphalt dipping process of the waterproof membrane base.

[0054] Please refer to Figure 1 and Figure 3 As shown, a control panel 19 is fixedly installed on the side wall of the immersion tank 3, and the control panel 19 is electrically connected to the electric push rod 9, the heating fan 21 and the temperature sensor 29.

[0055] The control circuit of the control panel 19 can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail. The control panel 19 is connected to an external power supply through wires for convenient power supply.

[0056] Please refer to Figure 1 and Figure 2 As shown, a safety door 15 is installed on one side of the immersion tank 3 via a hinge 14.

[0057] The safety door 15 is connected to one side of the immersion tank 3 via a hinge 14, which allows operators to easily open it to perform threading operations, equipment maintenance and cleaning inside the immersion tank 3. At the same time, closing it during operation can prevent asphalt splashing and heat loss, thus improving the ease of operation and production safety.

[0058] Please refer to Figure 6 As shown, the cross-sectional shape of the gas distribution box 31 is a U-shape.

[0059] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, support legs 2 are welded to the four corners of the bottom surface of the immersion tank 3, and mounting base plate 1 is welded to the bottom of the support legs 2. Fixing blocks 18 are welded to the four corners of the mounting base plate 1.

[0060] The support legs 2 welded to the four corners of the bottom surface of the immersion tank 3 and the mounting base plate 1 welded to its bottom, together with the fixing blocks 18 welded to the four corners of the mounting base plate 1, provide a stable support foundation and reliable on-site fixing structure for the entire device. This effectively resists the vibration and impact generated by the electric push rod 9 driving the lifting plate 25 to rise and fall and the continuous traction of the tire base during equipment operation, ensuring that the immersion tank 3 and the anti-drip box 11 remain horizontal and stable. This ensures the vertical guiding accuracy of the tire base immersion pressure roller 27 and the blowing consistency of the air knife nozzle 34, improving the stability and safety of the entire machine operation.

[0061] Working principle: This invention is equipped with an inlet roller 7, an outlet roller 10, and a safety door 15. A first fixing frame 6 is bolted to one side wall of the immersion tank 3, and the inlet roller 7 is mounted on the first fixing frame 6. A second fixing frame 13 is bolted to the other side wall of the immersion tank 3, and the outlet roller 10 is mounted on the second fixing frame 13. Simultaneously, a safety door 15 is connected to one side of the immersion tank 3 via a hinge 14. An electric push rod 9 is bolted to the center of the top surface of the immersion tank 3, and a lifting plate 25 is fixedly connected to the output end of the electric push rod 9. Mounting shafts 26 are symmetrically fixed to both ends of the lifting plate 25, and immersion pressure rollers 27 are mounted on the mounting shafts 26. A tire base square tube 5 is connected to one side of the top surface of the immersion tank 3 for immersion coating. A third fixing frame 12 is welded to the other side of the top surface of the tank 3, and a drip-proof box 11 connecting the inner cavity of the dipping tank 3 is welded to one side of the third fixing frame 12. Before use, the user can open the safety door 15 and allow the waterproof membrane base to bypass the guide roller 7 and enter the inner cavity of the dipping tank 3 through the base inlet square tube 5. The waterproof membrane base then bypasses two immersion pressure rollers 27 and is introduced into the inner cavity of the drip-proof box 11, and finally exits around the outlet roller 10. The waterproof membrane base is continuously input along this path under the traction of the traction mechanism to facilitate the subsequent asphalt dipping operation of the waterproof membrane base. The operation is simple and convenient and can be used continuously. In addition, the present invention is equipped with an asphalt inlet pipe 4, an asphalt outlet pipe 17 and a heating chamber 28. A heating chamber 28 is opened inside the side wall of the dipping tank 3. 8. A heat transfer oil inlet pipe 23 is connected to one side of the bottom of the heating chamber 28, and a heat transfer oil outlet pipe 24 is connected to one side of the bottom of the heating chamber 28. Meanwhile, an asphalt inlet pipe 4 is connected to one side of the inner cavity of the immersion tank 3, and an asphalt outlet pipe 17 is connected to the bottom of the inner cavity of the immersion tank 3. A drain valve 16 is installed on the asphalt outlet pipe 17. Before use, the user can introduce the heated asphalt liquid into the inner cavity of the immersion tank 3 through the asphalt inlet pipe 4 for asphalt impregnation processing of the waterproof membrane base. The heat transfer oil inlet pipe 23 and the heat transfer oil outlet pipe 24 can be connected to an external heat transfer oil circulation heating device. By circulating heat transfer oil at a certain temperature into the heating chamber 28, the asphalt liquid in the inner cavity of the immersion tank 3 can be kept warm. Heating is provided. A temperature sensor 29 is fixedly installed inside the immersion tank 3 to monitor the temperature change of the asphalt liquid. When the temperature is stable, the viscosity and surface tension of the asphalt also remain stable, thereby improving the asphalt immersion coating processing quality of the waterproof membrane base. If the temperature is too low, the asphalt will thicken and its fluidity will decrease, which is not only detrimental to the product processing quality, but also makes it difficult for the subsequent anti-drip mechanism to effectively remove excess asphalt material. Asphalt dripping is still likely to occur after the product is discharged. After the equipment is stopped, the user can open the drain valve 16 to discharge the unused asphalt liquid, preventing the asphalt from cooling and solidifying inside the immersion tank 3 and affecting the next use of the device. The present invention is equipped with an immersion tank 3, an immersion pressure roller 27, and an anti-drip box 11. As described above, after completing the pre-processing preparation,The user can activate the electric push rod 9 via the control panel 19 to push the waterproof membrane base into the asphalt liquid for impregnation. The immersion depth and immersion length can be adjusted according to the actual production process and the device specifications and dimensions are not mandatory. After impregnation with asphalt, the waterproof membrane base can enter the inner cavity of the anti-drip box 11 under the traction of external equipment. The anti-drip box 11 has a fixed air distribution box 31 installed in the inner cavity, and several sets of mounting seats 33 are symmetrically installed on the inner wall of the air distribution box 31. Air knife nozzles 34 are fixedly installed on the mounting seats 33. At the same time, the side wall of the anti-drip box 11 is bolted to the mounting base 20, and the mounting base 20 is fixedly installed with a heating fan 21. The input end of the heating fan 21 is connected to the air inlet pipe 22, and the output end of the heating fan 21 is connected to one end of the air outlet pipe 30. The other end of the air outlet pipe 30 is connected to... The air is connected to the inner cavity of the uniform air distribution box 31. External air is drawn into the inner cavity of the heating fan 21 through the air inlet pipe 22 and heated. Then, it is introduced into the inner cavity of the uniform air distribution box 31 through the air outlet pipe 30. The hot air is sprayed out at an angle through the nozzle, producing high-temperature and high-pressure gas. At the same time, it blows away or atomizes excess asphalt on both sides of the roll surface. The hot air acts as an air knife, which can smooth and thin out the wavy lines, drips, and thick edges formed on the surface due to gravity or excessive coating. This directly reduces the total amount of asphalt that needs to be cooled afterward. At the same time, the surface asphalt is re-leveled, forming a liquid film with a more uniform thickness and a smoother surface. The direction of gravity is exactly opposite to the upward movement direction of the roll material. Excess asphalt will flow directly back into the tank under the action of gravity, instead of being carried out by the roll material and dripping. The processed asphalt particles will fall back into the inner cavity of the impregnation tank 3 for heating, so as to achieve recycling and avoid asphalt waste.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
