Description

Technical Field

[0001] This utility model belongs to the field of waterproof coating production technology, specifically relating to a modified emulsified asphalt waterproof coating processing and filling device. Background Technology

[0002] In the production process of modified emulsified asphalt waterproof coatings, the addition of emulsifiers and various additives (such as thickeners and defoamers) to the soap solution tank mainly relies on manual feeding. This method has the following problems:

[0003] The core drawback of manual material addition lies in the difficulty of achieving uniform and consistent material distribution. Operators must pour solid or high-viscosity emulsifiers and additives directly into the soap solution tank. During this process, materials are prone to accumulating rapidly, creating localized high-concentration areas. For example, if anionic emulsifiers accumulate in large quantities within a short period, they cannot readily integrate with water, forming micelle agglomerates. These agglomerates not only fail to perform emulsification but also become impurity nuclei in subsequent asphalt emulsification processes, leading to coarse emulsion particles, a sharp drop in stability, and ultimately, product stratification or demulsification. For polymeric additives such as thickeners, manual addition is even more prone to uneven dispersion, forming "fish-eye" gel particles that directly affect the viscosity uniformity of the coating, resulting in inconsistent film thickness and fluctuating waterproofing performance during application.

[0004] The randomness of manual operation further amplifies quality risks. Different operators have different feeding speeds and strengths, and even the same person cannot maintain a consistent rhythm in different batches of production. This deviation is directly reflected in key indicators such as the solid content and viscosity of emulsified asphalt, forcing companies to add post-production optimization processes, which both prolongs the production cycle and increases the raw material loss rate.

[0005] In addition, in large-scale production, manual feeding is labor-intensive and has obvious efficiency bottlenecks, making it difficult to match the rhythm of continuous production lines. It often leads to the shutdown of previous processes due to waiting for feeding. Utility Model Content

[0006] To address the above problems, the purpose of this utility model is to provide a processing and feeding device for modified emulsified asphalt waterproof coatings, which solves the problems of uneven material addition, unstable speed, high labor intensity, and low efficiency in the traditional manual feeding process for modified emulsified asphalt waterproof coatings.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a modified emulsified asphalt waterproof coating processing and filling device, comprising a soap solution tank and a feeding assembly. The bottom of the soap solution tank is connected to the top of a three-way pipe. The horizontal port and bottom end of the three-way pipe are respectively connected to a circulation valve and a tank bottom valve. The circulation valve is connected to the inlet of a circulation pump through a pipe. The feeding assembly includes a five-way pipe one and a five-way pipe two. The four opposite ports of the five-way pipe one and the five-way pipe two are respectively connected to the two ends of four venturi tubes. The throat of the venturi tube is connected to the top of a feed pipe. A feed valve is installed at the bottom of the feed pipe. The four feed valves are respectively connected to the bottom of four storage tanks through pipes. A diversion valve is installed between the four ports of the venturi tubes and the five-way pipe one. The other port of the five-way pipe one is connected to the outlet of the circulation pump. The other port of the five-way pipe two is connected to the top of the soap solution tank.

[0008] The beneficial effects of this utility model are as follows: by controlling the valve status of the four diversion valves and the feed valve, the emulsifier and additives stored in multiple storage tanks can be uniformly and negatively pumped into the soap liquid tank, avoiding uneven feeding or clumping due to excessive speed, and effectively reducing the amount of labor required for feeding.

[0009] To ensure the stability of the feeding assembly;

[0010] As a further improvement to the above technical solution: the five-way pipe one and five-way pipe two are arranged opposite to each other on the top surface of the main support, and are fixed to the main support by U-shaped pipe clamps sleeved on the outside of the five-way pipe one and five-way pipe two. The main support is a frame structure composed of multiple channel steels welded together.

[0011] The beneficial effects of this improvement are: the main support can provide stable support for five-way pipe one and five-way pipe two, ensuring the stability of the feeding component.

[0012] To provide stable support for the storage tank;

[0013] As a further improvement to the above technical solution: two support plates are welded to each other on the side of the storage tank. The support plates are fixed to the top of the secondary support, and the two ends of the secondary support are welded to the main support.

[0014] The beneficial effects of this improvement are: the secondary support can provide stable support for the storage tank, and through its connection with the main support, it can maintain a stable relative position between the storage tank and the five-way pipe one, five-way pipe two, and venturi pipe.

[0015] In order to effectively pump out the material stored in the storage tank;

[0016] As a further improvement to the above technical solution: the lower tank body of the storage tank has a tapered groove structure that gradually tapers from top to bottom.

[0017] The beneficial effects of this improvement are: the emulsifier, thickener, bactericide and defoamer stored in the four storage tanks can all enter the pipe connected to the bottom of the storage tank along the inclined inner wall of the storage tank, avoiding the situation of material accumulation in the dead corner of the discharge.

[0018] To prevent moisture from flowing back into the storage tank through the five-way pipe and venturi pipe after the material extraction is completed, thus affecting the quality of the next feeding;

[0019] As a further improvement to the above technical solution: a top valve is installed between the five-way pipe and the top of the soap dispenser.

[0020] The beneficial effect of this improvement is that after the top valve of the tank is closed, water vapor can be effectively prevented from flowing back into the storage tank through the five-way pipe and the venturi pipe.

[0021] To intuitively and accurately determine the flow of liquid in the feeding assembly;

[0022] As a further improvement to the above technical solution: a pressure gauge is installed between the liquid soap container and the top of the container.

[0023] The beneficial effects of this improvement are: operators can use the pressure gauge to monitor the pressure inside the pipe to determine whether the venturi tube is blocked, thereby maintaining the feeding assembly in a timely manner to avoid affecting production efficiency.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0030] Example 1:

[0031] like Figure 1 As shown in Figure 3: A modified emulsified asphalt waterproof coating processing and filling device includes a soap solution tank 1 and a feeding assembly 5. The bottom of the soap solution tank 1 is connected to the top of a three-way pipe 2. The horizontal port and bottom end of the three-way pipe 2 are respectively connected to a circulation valve 3 and a tank bottom valve. The circulation valve 3 is connected to the inlet of a circulation pump 4 through a pipe. The feeding assembly 5 includes a five-way pipe 1 8 and a five-way pipe 2 9. The four opposite ports of the five-way pipe 1 8 and the five-way pipe 2 9 are respectively connected to the two ends of four Venturi tubes 10. The throat of the Venturi tube 10 is connected to the top of a feed pipe 11. A feed valve 12 is installed at the bottom end of the feed pipe 11. The four feed valves 12 are respectively connected to four storage tanks through pipes. At the bottom of the material tank 13, a diversion valve 14 is installed between the four ports of the Venturi tube 10 and the first five-way pipe 8. Another port of the first five-way pipe 8 is connected to the outlet of the circulating pump 4, and another port of the second five-way pipe 9 is connected to the top of the soap liquid tank 1. By controlling the valve states of the four diversion valves 14 and the feed valve 12, the emulsifier and additives stored in multiple storage tanks 13 can be uniformly drawn into the soap liquid tank 1 under negative pressure, avoiding uneven or excessively rapid feeding and effectively reducing the labor required for feeding. The first five-way pipe 8 and the second five-way pipe 9 are positioned opposite each other on the top surface of the main support 6 and are fixed by U-shaped pipe clamps fitted onto the outside of the first five-way pipe 8 and the second five-way pipe 9. On the main support 6, which is a frame structure composed of multiple welded channel steels, the main support 6 provides stable support for the five-way pipe 8 and the five-way pipe 9, ensuring the stability of the feeding assembly 5. Two support plates 131 are welded to the sides of the storage tank 13, and the support plates 131 are fixed to the top of the secondary support 7. The two ends of the secondary support 7 are welded to the main support 6. The secondary support 7 provides stable support for the storage tank 13 and, through its connection with the main support 6, maintains a stable relative position between the storage tank 13 and the five-way pipe 8, the five-way pipe 9, and the venturi pipe 10. The lower part of the storage tank 13 has a tapered groove structure that gradually tapers from top to bottom, storing... The emulsifier, thickener, bactericide, and defoamer in the four storage tanks 13 can all enter the pipe connected to the bottom of the storage tank 13 along the inclined inner wall of the storage tank 13, avoiding the accumulation of material in the dead corner of the discharge. A tank top valve 15 is installed between the five-way pipe 2 9 and the top of the soap liquid tank 1. After the tank top valve 15 is closed, water vapor can be effectively prevented from flowing back into the storage tank 13 through the five-way pipe 2 9 and the venturi pipe 10. A pressure gauge 16 is installed between the five-way pipe 2 9 and the top of the soap liquid tank 1. The operator can use the pressure gauge 16 to monitor the pressure inside the pipe to determine whether the venturi pipe 10 is blocked, so as to maintain the feeding component 5 in time and avoid affecting the production efficiency.

[0032] The working principle of this technical solution is as follows: Close all feed valves 12. According to the production formula, emulsifier, thickener, defoamer, and bactericide are respectively loaded into the corresponding storage tanks 13 and the initial material quantity of each storage tank is recorded. Open the top valve 15 and circulation valve 3 of soap liquid tank 1, close the bottom valve, inject the preset amount of deionized water into the soap liquid tank, start the circulation pump 4, open the feed valve 12 of the corresponding storage tank 13 and the diversion valve 14 of the corresponding venturi pipe 10, keep the other three valves closed, the venturi pipe throat generates negative pressure due to the high-speed water flow, draws the emulsifier from the storage tank into the pipeline and mixes it with the water flow. Control the addition speed by finely adjusting the opening of the diversion valve 14, and observe the pressure gauge 16 at the same time. After the amount of emulsifier added reaches the formula requirements, first close the feed valve 12, and close the diversion valve 14 after a few seconds to avoid the backflow of residual material in the pipeline. Add other additives in the same order according to the same process. The circulation system needs to be kept running for 5 minutes to ensure that the material is fully diffused in the soap liquid tank.
