[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This application provides a resin tank system for resin filling, which solves the problem of slow filling speed when changing ton containers during the filling process. It realizes automated filling using the main tank 21, and multiple main tanks 21 can select the resin in the required main tank 21 for filling as needed. The filling speed is fast and ensures continuous production in the plant.

[0035] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0036] By excavating a pit 10 on the ground to store the main tank 21, the storage capacity is larger, and the less light below the ground can reduce the storage temperature. In addition, it can be used quickly when needed, ensuring the continuous operation of the plant.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] The system can consist of several main tanks 21. In one embodiment, it consists of four horizontal main tanks 21 and their auxiliary equipment. An overall refrigeration system is also added. Resin is supplied to each plant line through a central control system. Automatic protection and automatic monitoring of combustible gas concentration are also added to ensure the safe and stable operation of the entire resin tank area.

[0039] Reference Figures 1-3 A resin tank system for resin injection includes a combined resin tank 20, a foundation pit 10, etc.

[0040] Reference Figure 1 A resin tank system for resin injection includes a pit 10, which is located on the ground. A combined resin tank 20 is installed in the pit 10. An insulated air duct 30 is also installed in the pit 10 and is connected to an air conditioning room 31.

[0041] A foundation pit 10 is dug on the ground, and a combined resin tank 20 is placed inside the foundation pit 10. The bottom of the foundation pit 10 is compacted according to calculations, and reinforced concrete walls are built around it. The surface of the walls and the bottom of the foundation pit 10 are painted with anti-corrosion paint. This setting of the foundation pit 10 makes it easier to maintain a constant temperature, and the temperature can be more easily controlled below 30 degrees Celsius. In addition, there is less light inside the foundation pit 10, so it is not easy for the temperature to rise.

[0042] Light-proof unloading, movable pit cover 60, unloading box 61, personnel access allowed, resin gravity flow.

[0043] Reference Figure 2 In a further embodiment, the combined resin tank 20 includes several main tank bodies 21. Each main tank body 21 is provided with a discharge port 22, two manholes 23, a level gauge installation port 24, and a discharge port 25. The diameter of each of the two manholes 23 is 50cm. The discharge port 22 and the discharge port 25 are located on different sides and at different ends of the main tank body 21.

[0044] Through the discharge port 22, the resin liquid in the tanker can be quickly sent into the main tank 21. Since the main tank 21 is located underground and there is a height difference between it and the tanker, the resin liquid can quickly flow into the main tank 21 under its own gravity.

[0045] Two manholes 23 allow workers to quickly enter and exit the main tank 21 to perform cleaning and other operations. In addition, there are two manholes 23, located at both ends, which makes it more convenient to enter the main tank 21.

[0046] A level gauge can be quickly installed through the level gauge installation port 24, thereby quickly determining the amount of resin liquid in the main tank 21.

[0047] The resin liquid in the main tank 21 can be quickly discharged through the discharge port 25, making it convenient to pump to the factory for use.

[0048] In a further embodiment, the discharge port 22 is connected to a discharge solenoid valve 40, the discharge port 25 is connected to a discharge pipe 41, a three-way pipe 42 is connected to the discharge pipe 41, and a discharge solenoid valve 43 is connected to the discharge pipe 41. The three-way pipe 42 is connected to a rotor pump 44, the liquid level gauge installation port 24 is connected to an ultrasonic liquid level gauge 45, and the ultrasonic liquid level gauge 45 is connected to a main control computer 46.

[0049] During use, the opening and closing of the discharge solenoid valve 40 ensures that the material in the tanker is delivered into the main tank 21 in a timely manner, and the discharge solenoid valve 40 is closed when no material is being discharged.

[0050] The rotor pump 44 can be connected to one main tank 21 or two main tanks 21 through a three-way pipe 42, so that the rotor pump 44 can operate two main tanks 21, saving energy.

[0051] The amount of resin liquid in the main tank 21 can be quickly and accurately determined by the ultrasonic level gauge 45, and the measurement results of the ultrasonic level gauge 45 can also be quickly viewed by the main control computer 46.

[0052] In a further embodiment, each of the main tanks 21 further includes a first circulation port 50 and a second circulation port. The plurality of first circulation ports 50 are connected to each other through circulation pipes 52. The rotor pump 44 is connected to a feeding pipe 53. A feeding solenoid valve 56 is provided on the feeding pipe 53. A plurality of return pipes 54 are connected to the feeding pipe 53. Each return pipe 54 is connected to the second circulation port. A return solenoid valve 55 is also connected to the return pipe 54.

[0053] By setting the first circulation port 50 and the second circulation port, it can be ensured that the resin liquid can circulate within the main tank 21 itself or between main tanks 21.

[0054] In a further embodiment, the inner wall of the foundation pit 10 is made of reinforced concrete, and the inner wall of the foundation pit 10 is coated with anti-corrosion paint.

[0055] Reinforced concrete walls can reinforce the inner walls of the foundation pit, while applying anti-corrosion paint can prevent corrosion and extend service life.

[0056] In a further embodiment, a movable pit cover 60 is provided on the top of the pit 10, and a discharge box 61 is also provided on one side of the pit 10. The discharge box 61 is used to cover the discharge port 22.

[0057] Opening the movable pit cover 60 allows entry into the pit 10, enabling operation of the equipment within. The unloading box 61 reduces sunlight exposure during unloading, ensuring the resin's fluidity and preventing condensation.

[0058] The unloading box 61 can be set to be accessible to people, so that the unloading pipe can be connected to the discharge port 22.

[0059] In a further embodiment, a temperature feedback device 62 is also provided in the foundation pit 10, and the temperature feedback device 62 is electrically connected to the air conditioning room 31.

[0060] By connecting the air ducts to the indoor units of the air conditioner and each resin tank area, cooling of the entire tank area is achieved. The insulated air duct 30 is made of galvanized steel sheet, and the dimensions of each section of the air duct are determined according to the actual site dimensions and air volume of the equipment.

[0061] The installation of the insulated air duct 30 requires that the temperature at the air outlet of each tank area reach 21℃.

[0062] By placing the temperature feedback device 62 in the central resin tank area, the temperature changes of each section of the resin tank area can be monitored, and the changes can be fed back to the air conditioning system to achieve automatic temperature regulation and control.

[0063] In a further embodiment, the outlet temperature of the insulated air duct 30 is set to 21°C.

[0064] In another embodiment, the distance between the foundation pit 10 and the workshop is 6 meters or more.

[0065] This arrangement ensures that the distance between the foundation pit 10 and the workshop is not too far, thus preventing the foundation pit 10 from affecting the safety of the factory building. It is also close to the factory building, which can shorten the feeding pipe 53.

[0066] In a further embodiment, the main tank 21 is made of stainless steel, the wall thickness of the main tank 21 is 5mm, and the outer wall of the main tank 21 is coated with anti-corrosion paint.

[0067] In actual use, the tanker truck moves to the vicinity of the unloading box 61, the material pipe on the tanker truck is inserted into the unloading box 61 and connected to the discharge pipe and discharge port in the unloading box 61, the discharge solenoid valve 40 is opened, and the resin liquid flows into the main tank 21 under its own gravity.

[0068] After unloading is completed, close the discharge solenoid valve 40, and then open the rotor pump 44 as needed. The rotor pump 44 draws resin liquid from the main tank 21 and discharges it from the outlet 25 and the discharge pipe 41. To pump resin liquid from a specific main tank 21, open the corresponding discharge solenoid valve 43. The resin liquid drawn by the rotor pump 44 will be fed into the factory for processing along the feeding pipe 53. During this process, the feeding solenoid valve 56 is opened and the return solenoid valve 55 is closed.

[0069] When circulation is required, the feeding solenoid valve 56 is closed. If circulation is required between multiple main tanks 21, all return solenoid valves 55 are opened. In this way, the resin liquid drawn by the rotor pump 44 will enter multiple return pipes 54 along the feeding pipe 53, and then enter different main tanks 21, thus forming the circulation of resin liquid in multiple main tanks 21.

[0070] When a single main tank 21 needs to be circulated, the other return solenoid valves 55 are closed, leaving only the return solenoid valve 55 on the main tank 21 that needs to be circulated open. Then, the resin liquid drawn by the rotor pump 44 will only enter the corresponding return pipe 54 along the feed pipe 53 and then return to the main tank 21 that needs to be circulated. This achieves the circulation of the resin liquid in a single main tank 21.

[0071] In summary, compared with existing technologies, it has the following beneficial effects:

[0072] 1. While meeting environmental protection requirements, maximize the resin storage capacity in the plant to meet the resin demand during continuous operation of the production line.

[0073] 2. The tanks are interconnected, allowing resin to be extracted from any tank and put into any production line for operation;

[0074] 3. Add circulation equipment between each group of tanks to increase resin flow and prevent gel from clogging the pipes when the tanks are not used for a long time.

[0075] 4. By adding a refrigeration system, the resin can be stored at low temperatures for a long time, thus extending its service life.

[0076] 5. Operators only need to click the corresponding valve open / close button on the production line central control screen to realize resin extraction and filling, which reduces the production time of switching between ton containers and increases production efficiency.
