Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1 to 3 This utility model provides a storage device for sealing ethylene glycol, including a storage tank 1. The storage tank 1 has an injection port and an outlet fixedly connected to its two sides, respectively. The top of the storage tank 1 is covered by a cover plate 11. The top center of the cover plate 11 is fixedly connected to a conveying port 2. A sealing gasket 3 is fixedly connected inside the conveying port 2. The sealing gasket 3 is made of fluororubber and is embedded in the inner wall of the conveying port 2 through an annular groove. It can be replaced periodically. A feeding mechanism 4 is installed on the top of the storage tank 1.
[0018] The feeding mechanism 4 includes a support rod 41, a limiting block 42, and a storage box 43. A limiting groove 411 runs vertically through the interior of the support rod 41, and a fixing block 412 is fixedly connected to the support rod 41. A first screw 413 runs through the interior of the fixing block 412, and the limiting block 42 is threaded onto the external surface of the first screw 413. The storage box 43 is fixedly connected to the limiting block 42. A filling port 431 is fixedly connected to the top of the storage box 43, and a discharge port 432 is fixedly connected to the bottom of the storage box 43. A connector 433 is fixedly connected to the storage box 43. A load-bearing frame 44 is fixedly connected to the bottom of the storage box 43, and a second screw 45 runs through the internal thread of the load-bearing frame 44. A piston plate 46 is connected to the top of the second screw 45, and two O-rings are provided on the edge of the piston plate 46. To ensure a dynamic seal with the inner wall of the storage tank 43, a conveying pipe 47 is fixedly connected to the bottom of the support frame 44. A baffle 48 is fixedly fitted on the outside of the conveying pipe 47, and a sealing head 49 is fixedly connected to the top of the baffle 48. The sealing head 49 is fitted on the outside of the conveying pipe 47 and is located directly below the conveying port 2. The sealing head 49 and the conveying port 2 are compatible. The diameter of the baffle 48 is equal to the diameter of the conveying port 2. The connector 433 and the conveying pipe 47 are fixedly connected by a flexible hose. The flexible hose is made of PTFE material, 50cm in length, and resistant to ethylene glycol corrosion. Valves are installed inside the injection port 431, the discharge port 432, and the connector 433. The valve on the injection port 431 facilitates the injection of ethylene glycol into the storage tank 43, and the valve on the discharge port 432 facilitates storage. Ethylene glycol in tank 1 is drawn into storage tank 43 through conveying pipe 47 for pouring. A valve on connector 433 facilitates the injection of ethylene glycol from storage tank 43 into storage tank 1. The first screw 413 and fixing block 412 are rotatably connected via bearings. The bottom end of the first screw 413 is rotatably connected to the top of cover plate 11 via bearings. Limiting block 42 has an "H"-shaped structure and is slidably connected inside limiting groove 411. Support rod 41 is fixed to the top of storage tank 1. Second screw 45 is threaded through the bottom of storage tank 43. The second screw 45 and piston plate 46 are rotatably connected via bearings. An observation window is fixedly embedded in the front surface of storage tank 43, and scale lines are provided on the observation window. The bottom of conveying pipe 47 passes through sealing gasket 3, and then... Rotating the second screw 45 raises the piston plate 46, facilitating the metered transfer of ethylene glycol from the storage tank 43 to the storage tank 1. Similarly, reversing the second screw 45 lowers the piston plate 46, allowing the ethylene glycol in the storage tank 1 to be metered and collected via the delivery pipe 47. This method eliminates the need to open the injection and outlet ports to collect and empty the ethylene glycol in the storage tank 1, significantly reducing ethylene glycol volatilization and resource waste, while also minimizing environmental pollution. This method also facilitates the actual storage and use of ethylene glycol. Furthermore, rotating the first screw 413 forward causes the limit block 42, storage tank 43, support frame 44, delivery pipe 47, baffle 48, and sealing head 49 to rise.Once the sealing head 49 moves to the bottom of the conveying port 2, it can seal the bottom, further improving the sealing effect of the storage tank 1.
[0019] Working principle: When using this device, first fix the support rod 41 to the top of the cover plate 11, then pass the conveying pipe 47 through the sealing gasket 3, then put the baffle 48 and sealing head 49 on the conveying pipe 47 and fix the baffle 48 on the conveying pipe 47. Then fix the cover plate 11 to the top of the storage tank 1, and inject ethylene glycol into the storage tank 43 through the injection port 431. Both the injection port 431 and the discharge port 432 are equipped with valves to ensure no leakage during the injection process. The front surface of the storage tank 43 is... The device features a graduated observation window for real-time monitoring of ethylene glycol capacity. When ethylene glycol needs to be transferred to storage tank 1, the second screw 45 is rotated, causing the piston plate 46 to rise. The rising piston plate 46 generates pressure, forcing the ethylene glycol in storage bin 43 into storage tank 1 through conveying pipe 47. The conveying pipe 47 passes through sealing gasket 3 to ensure a tight seal during the transfer process. When ethylene glycol needs to be removed from storage tank 1, the second screw 45 is reversed, causing the piston plate 46 to descend. The descent of plate 46 generates negative pressure, drawing ethylene glycol from storage tank 1 into storage bin 43 through conveying pipe 47, achieving quantitative collection. Throughout this process, there is no need to open the injection or outlet of storage tank 1, effectively reducing ethylene glycol evaporation. When storage tank 1 is no longer needed for ethylene glycol conveying or collection, rotating the first screw 413 causes the limiting block 42, storage bin 43, support frame 44, conveying pipe 47, baffle 48, and sealing head 49 to rise as a whole. The sealing head 49 rises to... When the baffle 48 is at the bottom of the conveying port 2, it fits tightly against the conveying port 2 to form a seal, further preventing the evaporation of ethylene glycol. The diameter of the baffle 48 is equal to the diameter of the conveying port 2, ensuring the compatibility between the sealing head 49 and the conveying port 2 and improving the sealing effect. The storage box 43 is connected to the conveying pipe 47 through the connector 433 and the hose, which is convenient for disassembly and maintenance. The design of the limiting groove 411 and the "H"-shaped limiting block 42 on the support rod 41 ensures the stability of the storage box 43 during the lifting process and avoids deviation.
