Description

Technical Field

[0001] The utility model belongs to the technical field of storage tanks and relates to a storage tank cooling device. Background Art

[0002] Industrial storage tanks are pressure vessels commonly used in the food, petrochemical, and chemical industries to store liquids and gases. Large tanks can reach tens of meters in height and are typically located outdoors. In the summer, they are exposed to the scorching sun, causing the tanks to heat up. When storing substances such as gasoline, diesel, and organic solvents with low boiling points, the pressure inside the tank can rise, potentially leading to rupture. Therefore, when outdoor temperatures are high, tank cooling is essential.

[0003] For example, a utility model patent with application number CN202321114280.X provides a spray structure for cooling a liquefied natural gas storage tank, including a gas tank, a base fixedly provided at the lower end of the gas tank, a bracket fixedly provided at the upper end of the base, the base including a No. 1 connection port, a No. 2 connection port and a water outlet fixedly provided on one side of the base, an air pump and a water pump provided on one side of the base, the bracket including a ring frame provided on the bracket, a connecting column fixedly provided on the upper end of the bracket, and a No. 2 channel opened inside the bracket, wherein three groups of ring frames are provided.

[0004] In summary, although some existing technical solutions have solved the problem of cooling the storage tank body, since the water droplets generated by spraying are easily blown away by the wind, the storage tank body cannot be effectively cooled, and there is much room for improvement. Summary of the Invention

[0005] The purpose of this utility model is to solve the above problems existing in the prior art and propose a storage tank cooling device, comprising:

[0006] Tank body;

[0007] a water outlet pipe, aligned with the top of the storage tank body;

[0008] A water collecting trough is arranged on the circumference of the tank body and there are at least two of them. Each of the water collecting troughs is distributed along the height direction of the tank body. The water collecting trough includes a water collecting lower part and a water collecting upper part. The water collecting upper part is connected to the water collecting lower part. A water-passing gap is formed between the water collecting lower part and the tank body. A water collecting space is formed between the water collecting upper part and the tank body. The water collecting space is larger than the water collecting gap.

[0009] The above-mentioned storage tank cooling device further includes rotating blades, which are rotatably connected to the water outlet pipe.

[0010] In the above-mentioned storage tank cooling device, it also includes an impeller, which includes a rotating seat and rotating blades. The rotating seat is rotatably connected to the water outlet pipe. The number of the rotating blades is at least two, and each of the rotating blades is distributed around the center of the rotating seat. A water flow space is formed between two adjacent rotating blades.

[0011] In the above-mentioned storage tank cooling device, a bearing is further included. The water outlet pipe is provided with a first contact surface, and the rotating seat is provided with a second contact surface. The first contact surface contacts the second contact surface through the bearing.

[0012] In the above-mentioned storage tank cooling device, the first contact surface is the top surface of the bottom of the water outlet pipe, and the second contact surface is the bottom surface of the top of the rotating seat.

[0013] In the above-mentioned storage tank cooling device, the water collecting tank is provided with an overflow pipe, one end of the overflow pipe is provided at the lower part of the water collecting tank, and the other end of the overflow pipe is provided at the upper part of the water collecting tank.

[0014] In the above-mentioned tank cooling device, the overflow pipe includes a first vertical channel, a horizontal channel and a second vertical channel. One end of the first vertical channel is arranged at the lower part of the water collection, and the other end of the first vertical channel is connected to one end of the second vertical channel through the horizontal channel. The other end of the second vertical channel is arranged at the upper part of the water collection.

[0015] In the above-mentioned storage tank cooling device, it also includes a water collecting base, which is arranged at the bottom of the storage tank body and below the water collecting tank, and the water collecting base is provided with a collecting pipe.

[0016] The above-mentioned storage tank cooling device further includes a water tank, and the collecting pipe is aligned with the water tank.

[0017] The above-mentioned storage tank cooling device further includes a water pump, the suction port of the water pump extends into the water storage tank, and the water outlet pipe is connected to the discharge port of the water pump.

[0018] In the above-mentioned storage tank cooling device, the cross-sectional area of ​​the water gap is the same as the cross-sectional area of ​​the water outlet pipe.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The cooling water starts to flow from the top of the tank body through the outlet pipe, covering the entire outer surface of the tank body. When the water flows through the water collecting tank, part of the cooling water will be intercepted by the water collecting tank, which not only slows down the speed of the water flow, but also makes the cooling water more evenly distributed along the surface of the tank body, and finally forms a continuous and uniform water film flowing downward. This process effectively ensures full contact between the cooling water and the tank surface, thereby improving the cooling efficiency.

[0021] 2. The rotating blades are rotatably connected to the water outlet pipe. When the cooling water flows out of the water outlet pipe, the cooling water contacts the rotating blades and drives the rotating blades to rotate. At the same time, the rotating blades during the rotation process can make the cooling water flowing out of the water outlet pipe more evenly distributed on the top of the tank body, thereby improving the cooling efficiency.

[0022] 3. The design of the overflow pipe effectively prevents excessive accumulation of cooling water in the water collection tank and avoids its overflow. In addition, it can further optimize the drainage efficiency, making the water film formed by the cooling water more stable and improving the cooling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0035] The specific embodiments described herein are merely examples of the present utility model. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the scope of the present utility model or exceeding the scope defined by the appended claims.

[0036] like Figure 1-Figure 5 As shown, a storage tank cooling device includes: a storage tank body 1, a water outlet pipe 2 and a water collecting tank 3.

[0037] The water outlet pipe 2 is aligned with the top of the storage tank body 1 .

[0038] Among them, the water collecting trough 3 is arranged on the periphery of the tank body 1 and the number is at least two. Each of the water collecting troughs 3 is distributed along the height direction of the tank body 1. The water collecting trough 3 includes a water collecting lower part 32 and a water collecting upper part 31. The water collecting upper part 31 is connected to the water collecting lower part 32. A water gap 33 is formed between the water collecting lower part 32 and the tank body 1. A water collecting space 34 is formed between the water collecting upper part 31 and the tank body 1. The water collecting space 34 is larger than the water collecting gap.

[0039] Specifically, the cooling water flows out from the outlet pipe 2, flows to the top of the tank body 1 and flows down along the surface of the tank body 1. When flowing through the water collecting tank 3, part of the cooling water flows downward from the water gap 33, and part of it will temporarily remain in the water collecting space 34 and continue to flow downward from the water gap 33 with the subsequent cooling water.

[0040] In this embodiment, the cooling water starts to flow from the top of the tank body 1 through the outlet pipe 2, covering the entire outer surface of the tank body 1. When the water flows through the water collecting tank 3, part of the cooling water will be intercepted by the water collecting tank 3, which not only slows down the speed of the water flow, but also promotes the cooling water to be more evenly distributed along the surface of the tank body 1, and finally forms a continuous and uniform water film flowing downward. This process effectively ensures full contact between the cooling water and the tank surface, thereby improving the cooling efficiency.

[0041] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, it also includes an impeller 4, the impeller 4 includes a rotating seat 41 and rotating blades 42, the rotating seat 41 is rotatably connected to the water outlet pipe 2, the number of the rotating blades 42 is at least two, each of the rotating blades 42 is distributed around the center of the rotating seat 41, and a water flow space 43 is formed between two adjacent rotating blades 42.

[0042] Specifically, the rotating seat 41 is rotatably connected to the water outlet pipe 2, and the rotating blades 42 have an arc or the connection angle between the rotating blades 42 and the rotating seat 41 is inclined so that the rotating seat 41 can be driven to rotate when the cooling water flushes the rotating blades 42.

[0043] In this embodiment, the rotating blades 42 are rotatably connected to the water outlet pipe 2. When the cooling water flows out of the water outlet pipe 2, the cooling water contacts the rotating blades 42 and pushes the rotating blades 42 to rotate. At the same time, the rotating blades 42 during the rotation process can make the cooling water flowing out of the water outlet pipe 2 more evenly distributed on the top of the tank body 1, thereby improving the cooling efficiency.

[0044] like Figure 1-Figure 5As shown, based on the above embodiment, it further includes a bearing 5, the water outlet pipe 2 is provided with a first contact surface 21, and the rotating seat 41 is provided with a second contact surface 411, and the first contact surface 21 contacts the second contact surface 411 through the bearing 5.

[0045] In this embodiment, the first contact surface 21 contacts the second contact surface 411 through the bearing 5, which can reduce the friction between the rotating seat 41 and the water outlet pipe 2, so that the impeller 4 can rotate easily, while reducing the wear between the rotating seat 41 and the water outlet pipe 2 and extending the service life.

[0046] like Figure 1-Figure 5 As shown, based on the above embodiment, the first contact surface 21 is the top surface of the bottom of the water outlet pipe 2 , and the second contact surface 411 is the bottom surface of the top of the rotating seat 41 .

[0047] In this embodiment, the rotating seat 41 can be raised and lowered along with the height direction of the water outlet pipe 2. When the water flow in the water outlet pipe 2 is too large, the impact on the rotating blades 42 will cause the impeller 4 to rise, thereby reducing the impact of the water flow on the impeller 4, avoiding wear and damage caused by long-term high-intensity impact, and thus extending the practical life of the equipment.

[0048] like Figure 1-Figure 5 As shown, based on the above embodiment, the water collecting tank 3 is provided with an overflow pipe 35 , one end of the overflow pipe 35 is provided at the water collecting lower part 32 , and the other end of the overflow pipe 35 is provided at the water collecting upper part 31 .

[0049] Specifically, when the cooling water level in the water collection space 34 rises and reaches the set value, the cooling water will flow into one end of the overflow pipe 35 set at the upper water collection part 31 and flow out from the other end of the overflow pipe 35 set at the lower water collection part 32, thereby preventing the cooling water in the water collection tank 3 from overflowing.

[0050] In this embodiment, the design of the overflow pipe 35 effectively prevents excessive accumulation of cooling water in the water collecting tank 3 and avoids its overflow. In addition, it can further optimize the drainage efficiency, making the water film formed by the cooling water more stable and improving the cooling efficiency.

[0051] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, the overflow pipe 35 includes a first vertical channel 351, a horizontal channel 352 and a second vertical channel 353, one end of the first vertical channel 351 is arranged at the lower water collection part 32, the other end of the first vertical channel 351 is connected to one end of the second vertical channel 353 through the horizontal channel 352, and the other end of the second vertical channel 353 is arranged at the upper water collection part 31.

[0052] In this embodiment, the horizontal channel 352 connects the first vertical channel 351 and the second vertical channel 353 to form a horizontal transition section, which can help reduce bubbles in the water flow, ensure that the cooling water flowing out of the first vertical channel 351 is smooth, and keep the water film around the tank body 1 stable.

[0053] like Figure 1-Figure 5 As shown, based on the above embodiment, it further includes a water collecting base 6, which is arranged at the bottom of the storage tank body 1 and below the water collecting tank 3, and the water collecting base 6 is provided with a collecting pipe 61.

[0054] In this embodiment, the water collecting base 6 can be used to collect the cooling water flowing down the surface of the storage tank body 1, and output the collected cooling water to the storage device through the collecting pipe 61, thereby reducing the waste of cooling water resources.

[0055] like Figure 1-Figure 5 As shown, based on the above embodiment, it further includes a water tank 7, and the collecting pipe 61 is aligned with the water tank 7.

[0056] In this embodiment, the cooling water collected by the water collecting base 6 is stored in the water storage tank 7, which can effectively manage and subsequently utilize the cooling water and reduce resource waste. After the cooling water absorbs heat from the storage tank body 1 and is brought into the water storage tank 7, during the night period, the cooling water in the water storage tank 7 can release the heat to the environment through natural heat dissipation without the need for additional cooling treatment, thereby reducing energy consumption. This design not only improves the energy efficiency of the system, but also enhances the sustainable use of resources.

[0057] like Figure 1-Figure 5 As shown, based on the above embodiment, it further includes a water pump 8, the suction port of the water pump 8 extends into the water storage tank 7, and the water outlet pipe 2 is connected to the discharge port of the water pump 8.

[0058] In this embodiment, cooling water is extracted from the water tank 7 by the water pump 8 and then transported to the top of the tank body 1 through the outlet pipe 2, thereby realizing the reuse of cooling water and greatly improving the utilization rate of resources. This design not only effectively saves water resources, but also enhances the sustainability and economy of the system.

[0059] like Figure 1-Figure 5 As shown, based on the above embodiment, the cross-sectional area of ​​the water gap 33 is the same as the cross-sectional area of ​​the water outlet pipe 2 .

[0060] In this embodiment, when the cross-sectional area of ​​the water gap 33 matches the cross-sectional area of ​​the outlet pipe 2, it can ensure that the water flow remains balanced during the process of entering and exiting the water collection tank 3, and the water flow velocity or pressure will not change due to the inconsistency of the cross-sectional area, thereby causing water level fluctuations or other unstable phenomena.
