Description

Technical Field

[0001] This utility model belongs to the field of chemical tank technology, specifically relating to an anti-condensation and solidification tank. Background Technology

[0002] In the chemical production field, chemical storage tanks are core equipment used for storing and processing raw materials and intermediates. To process raw materials into finished products meeting specific specifications, the materials typically undergo a series of complex processes within the chemical tank, including raw material pretreatment, chemical reactions, and the separation and purification of reaction products. These processes often require the tank to be equipped with various auxiliary devices, among which the feeding device is a key component, enabling the efficient and controllable addition of liquid or slurry-like raw materials into the main tank.

[0003] Currently, common chemical storage tanks are typically equipped with fixed feeding pipelines, which can be directly connected to external feed tanks or storage vessels via pump and valve systems, forming a closed feeding system. This design reduces the volatilization, leakage, and safety risks that may arise from open feeding systems, and to some extent improves automation levels and production efficiency.

[0004] However, this existing feeding device has a significant technical drawback: after feeding is completed, a certain amount of residual raw material liquid will inevitably remain inside the feeding pipe located outside the chemical tank or penetrating the tank wall. For certain special chemical raw materials with high viscosity, easy solidification, or sensitivity to temperature and oxygen (such as certain polymer monomers, hot-melt resins, easily crystallizing solutions, etc.), if these residues remain in the pipes without special treatment for a long time, they will gradually solidify, crystallize, or undergo denaturing reactions such as local polymerization and oxidation due to changes in ambient temperature, surface exposure, or their own chemical properties.

[0005] When the next feeding operation is performed, these denatured or solidified residues in the pipeline will be flushed and dissolved by the newly flowing raw materials and carried into the main body of the chemical tank. This will have serious consequences: not only will it contaminate the entire batch of newly added high-quality raw materials, leading to a decrease in product purity and substandard quality, but it may also introduce foreign substances that become unintended catalysts or terminators for the chemical reaction, interfering with the reaction process, and may even clog subsequent precision filters and nozzles, causing unplanned production shutdowns and a surge in equipment maintenance costs.

[0021] Please see Figure 1-2 A solidification prevention tank includes a tank body 1, a cleaning port 2 disposed on the top of the tank body 1, and a discharge valve 11 disposed on the bottom of the tank body 1. It also includes a feed pipe 3 disposed on the cylinder of the tank body 1. A feed valve 4 is provided at the connection between the feed pipe 3 and the tank body 1. One end of the feed pipe 3 is fixedly connected to the top of the tank body 1, and the other end of the feed pipe 3 is fixedly connected to a feeding device.

[0022] With the feeding device in place, in actual use, the tank body 1 is first fixed: a steel structure bracket 7 supports the tank body 1, ensuring that the bottom of the tank is at a height sufficient for the installation of subsequent components; a cleaning port 2 is reserved at the top of the tank, and a discharge port is provided at the bottom with a discharge valve 12, such as a ball valve or butterfly valve, for routine discharge or cleaning; the feed pipe 3 is installed: one end of the feed pipe 3 is welded or flanged to the top of the tank body 1, and a feed valve 4, such as an electric or manual shut-off valve, is installed at the connection to control the opening and closing of the feed. The other end of the feed pipe 3 extends to the bottom of the tank and connects to the output port of the feed pump 5;

[0023] The feeding device is installed and fixed with the feed pump 5. The feed pump 5, such as a centrifugal pump or screw pump, is fixed on the mounting plate 6 below the tank body 1. Stability is ensured by anchor bolts. The output port of the feed pump 5 is connected to the feed pipe 3 through a flange or high-pressure hose. The pump feed pipe 8 is connected. The input port of the feed pump 5 is connected to the pump feed pipe 8. The end of the pump feed pipe 8 is connected to the A port of a three-way directional valve, such as a three-way ball valve.

[0024] The circulation component is integrated, and the circulation pipe 9 is arranged as follows: The circulation pipe 9 is led out from the discharge port at the bottom of the tank 1. Support frames are installed along the pipeline to prevent shaking. The end of the circulation pipe 9 is connected to the B port of the three-way directional valve to form a material circulation loop. The three-way directional valve is configured as follows: The C port of the three-way directional valve is connected to the conveying pipe (such as to other storage tanks or production equipment). The valve body must support three-way switching function: Mode 1 (A→B): Circulation mode (material at the bottom of the tank is pumped back to the top of the tank);

[0025] Mode 2 (A→C): Outbound mode (supplying materials to external equipment);

[0026] Mode 3 (B→C): Direct discharge mode (material at the bottom of the tank is directly discharged).

[0027] Operating procedure, anti-coagulation circulation operation: Open the feed valve 4 and the discharge valve, switch the three-way directional valve to A→B mode (circulation mode), start the feed pump 5, the material at the bottom of the tank is pumped into the feed pipe 3 through the circulation pipe 9, and sprayed back from the top of the tank to achieve dynamic mixing and anti-coagulation.

[0028] External feeding or conveying: Feeding: Connect to the external material source through the conveying pipe, switch the three-way directional valve to A→C mode, and start the feed pump 5 to convey material into the tank. Discharging: Switch the three-way directional valve to B→C mode and directly use the pressure inside the tank or gravity to convey material outward.
