Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a cooling water spray device for styrene storage tanks. Background Technology

[0002] Styrene storage tanks are specialized containers for storing styrene monomers. As an important chemical raw material, styrene is widely used in the production of polymer materials such as polystyrene, ABS resin, styrene-butadiene rubber, and unsaturated polyester resin. However, due to its flammable and volatile properties, and its tendency to undergo self-polymerization under high temperatures or impurities, styrene storage tanks pose significant safety risks. Therefore, styrene storage tanks must be equipped with cooling water spray systems. These systems not only inhibit styrene self-polymerization through continuous cooling, but also quickly form a water curtain to cover the tank itself or other surrounding tanks in case of fire, enabling emergency fire suppression. They are key facilities for ensuring storage safety and play an important role in preventing fires and curbing the spread of danger. The cooling water spray system for styrene storage tanks achieves safety protection through the heat absorption and physical barrier effect of water. Since styrene is prone to self-polymerization at high temperatures, the system evenly sprays cooling water through nozzles on the tank top and tank wall. The water absorbs heat from the tank through heat conduction, and then dissipates heat through evaporation and water flow, keeping the tank temperature within a safe threshold. In an emergency, if a fire breaks out in the tank or surrounding area, the system increases the spray to form a water film covering the tank wall, blocking the heat radiation of the flames and cooling the tank to prevent the styrene inside from getting out of control. At the same time, it sprays water mist to the surrounding area to dilute the concentration of styrene vapor, suppress the spread of fire, and ensure storage safety. Currently, cooling water spray systems for styrene storage tanks play a positive role in promoting industry safety and styrene storage safety. Through continuous cooling and emergency fire extinguishing functions, they effectively suppress the risk of styrene self-polymerization caused by high temperatures and reduce the probability of fire accidents. However, existing systems often have the problem of spraying at a single angle, which has obvious limitations. The nozzles are often arranged in a fixed direction along the tank wall, resulting in uneven water flow coverage on the tank surface. Some areas (such as the side facing away from the nozzles or structural obstructions) will form heat dissipation blind spots. These areas are difficult to cool sufficiently and will become local high-temperature points. This will not only induce styrene self-polymerization, but also affect the stability of the tank due to long-term temperature differences, posing a potential threat to the overall storage safety. Therefore, a cooling water spray system for styrene storage tanks is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a cooling water spraying device for styrene storage tanks, which aims to improve the problem of single-angle spraying of nozzles in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cooling water spraying device for a styrene storage tank includes a tank body, a fixing block fixedly connected to the outer wall of the tank body, a direct current pipe fixedly connected to the inner wall of the fixing block, an annular pipe fixedly connected to the top of the direct current pipe, a plurality of spraying mechanisms fixedly connected to the inner wall of the annular pipe, a plurality of supports fixedly connected to the outer wall of the tank body, and a reinforcing mechanism fixedly connected to the outer wall of the tank body.

The above technical solution involves a transmission component that includes a connecting column that moves synchronously with the slider. The base has through holes to provide space for the movement of related components. A connecting plate is mounted on the outside of the nozzle, which works with the connecting column to achieve transmission. When the slider moves within the base, the connecting column drives the nozzle to rotate through the connecting plate, flexibly adjusting the spray angle, eliminating blind spots caused by fixed-angle spraying, ensuring that cooling water evenly covers the tank, and improving the cooling efficiency and safety of the styrene storage tank.

[0008] As a further description of the above technical solution: The gear and the outer rack plate are meshingly connected, and the outer rack plate and the inner rack plate are meshingly connected; The above technical solution involves the gear meshing with both the outer and inner rack plates.

This sliding fit provides guidance for the movement of the components, ensures the stability of the transmission process, and allows the nozzle to flexibly adjust the angle, thereby improving the spray coverage effect.

[0011] As a further description of the above technical solution: The base has a convex cross-section, and the two heat insulation sleeves are fixedly connected to the top and bottom of the fixing block on their adjacent sides, respectively.

The two heat insulation sleeves 71 are fixedly connected to the top and bottom of the fixing block 2 on their adjacent sides, respectively. The heat insulation sleeves 71 wrap around the DC pipe 3 near the fixing block 2, completely blocking heat exchange, enhancing the heat insulation effect, and ensuring stable cooling water temperature.

Two heat insulation sleeves 71 wrap around the DC pipe 3 near the fixing block 2, blocking heat exchange, enhancing the heat insulation effect, and ensuring stable cooling water temperature.

[0019] Working principle: The motor 56 located on the inner wall of the slider 55 is started, and the driving force of the motor 56 drives the gear 57 to rotate. Thanks to the presence of the inner rack plate 53 and the outer rack plate 54 on the inner wall of the base 52, the gear 57 can be driven by the motor 56 on the inner wall of the base 52, thereby moving the slider 55. Thanks to the mutual cooperation of the connecting column 591 and the connecting plate 593 to transmit force, and the limiting effect of the through hole 592 on the connecting column 591, the nozzle 58 can rotate with the different positions of the slider 55. Thus, the cooling water inside the annular pipe 4 can be evenly sprayed out by the nozzle 58 through the transmission of the connecting pipe 51, so that the spraying angle of the entire device is no longer uniform, thereby greatly improving the working efficiency of the entire device. Thanks to the presence of the wind baffle 74 on the outer wall of the tank 1, the loss of cooling water caused by wind or splashing is reduced, thereby improving the utilization rate of water resources. Thanks to the presence of the fixing block 2, the DC pipe 3 can be installed firmly and stably. Thanks to the presence of the bracket 6, the annular pipe 4 can be installed firmly and stably. Thanks to the presence of the fixing plate 72, the booster pump 73 can be firmly fixed, and the booster pump 73 can significantly increase the water pressure inside the DC pipe 3, thereby enabling the entire device to operate stably. Thanks to the presence of the heat insulation sleeve 71, the cooling water inside the fixing block 2 will not exchange heat with the outside, which indirectly improves the operating efficiency of the entire device, and can also prevent the cooling water inside the fixing block 2 from freezing in the cold winter season, thus greatly improving the stability of the entire device.
