Description

Technical Field

[0001] This utility model belongs to the field of oil storage tank technology. Specifically, this utility model relates to a rolling support device for a heat transfer oil storage tank. Background Technology

[0002] The thermal storage compressed air energy storage power station uses heat transfer oil as the heat exchange medium, with high- and low-temperature heat transfer oils stored in cold and hot oil tanks, respectively. During the compression phase, which operates for 8 hours at night, the low-temperature heat transfer oil flows out of the cold oil tank, enters the compressor-side oil-gas cooler for heat exchange, and then returns to the hot oil tank after its temperature rises. During the power generation phase, which operates for 4 hours during the day, the high-temperature heat transfer oil flows out of the hot oil tank, enters the turbine-side oil-gas cooler for heat exchange, and then returns to the cold oil tank after its temperature drops.

[0003] A patent application (patent number 201220575043.9, published on June 5, 2013) discloses an oil supply system for an organic heat carrier heater. The system includes a heater, a heat transfer oil coil inside the heater, and a heat transfer oil storage tank outside the heater. An expansion tank is located above the heat transfer oil storage tank and is connected in parallel with it. The height of the expansion tank is greater than the height of the heater. An oil-gas separator is installed between the expansion tank and the heater. This invention uses an expansion tank connected in parallel above the heat transfer oil storage tank to accommodate the thermal expansion of the heat transfer oil. It also allows for the venting of light components and low-boiling-point substances generated during operation. Furthermore, it allows for the application of pressure to maintain the flow of heat transfer oil, preventing oil interruption and making the organic heat carrier heater safer and more reliable.

[0004] In daily production activities, the medium inside the heat transfer oil storage tank after heat exchange may expand or contract due to temperature changes, causing lateral displacement and resulting in breakage of the connection between the bottom heat transfer oil storage tank saddle and the foundation embedded parts, which may affect subsequent normal production. Utility Model Content

[0005] The present invention aims to provide a rolling support device for heat transfer oil storage tanks that can prevent structural damage caused by the expansion and contraction of the tank body.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rolling support device for a heat transfer oil storage tank, comprising a support plate, the support plate being divided into a top plate and a bottom plate, the top plate being connected to a saddle of the heat transfer oil storage tank, the bottom plate being connected to a foundation embedded part, and a sliding structure being provided between the support plates, the sliding structure being a roller shaft disposed between the support plates.

[0007] The support plate has end plates on its side, and the roller shaft has an insert shaft that passes through the roller shaft and passes through the end plates on both sides.

[0008] The end plate is provided with a sliding groove, and the insertion shaft is located in the sliding groove.

[0009] The surface of the roller shaft is provided with a groove, and the support plate is provided with a limiting block that cooperates with the groove.

[0010] The grooves are evenly distributed on the surface of the roller.

[0011] The end of the roller shaft is chamfered, and the side of the limiting block is in contact with the chamfered surface of the roller shaft.

[0012] The end plate located on the base plate is located outside the ends of the two rollers.

[0013] The technical advantages of this invention are as follows: When the heat transfer oil storage tank changes temperature, the tank body undergoes lateral displacement, and the roller rolls between the upper and lower support plates, thereby adapting to the expansion or contraction of the tank body. At the same time, the rolling support can also bear the vertical load of the heat transfer oil storage tank and transfer it to the lower structure. It can also withstand large vertical loads and horizontal forces. The support does not require more complex anti-corrosion measures, has a low maintenance rate, stable working performance, is durable, and is safe and reliable. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0019] Please see Figure 1-2 A rolling support device for a heat transfer oil storage tank includes a support plate 1, which is divided into a top plate 11 and a bottom plate 12. The top plate 11 is connected to the saddle of the heat transfer oil storage tank, and the bottom plate 12 is connected to the foundation embedded parts. A sliding structure is provided between the support plates 1, which is a roller 2 set between the support plates 1. When the heat transfer oil storage tank changes due to temperature, the tank body undergoes lateral displacement, and the roller 2 rolls between the upper and lower support plates 1, thereby adapting to the expansion or contraction of the tank body. At the same time, the rolling support can also bear the vertical load of the heat transfer oil storage tank and transfer it to the lower structure.

[0020] The side of the support plate 1 is provided with an end plate 3, and the roller 2 is provided with an insert shaft 4 that passes through the roller 2. The insert shaft 4 passes through the end plates 3 on both sides. Through the cooperation of the end plate 3 and the insert shaft 4, the roller 2 can be kept between the upper and lower support plates 1 to avoid structural separation.

[0021] The end plate 3 is provided with a sliding groove 5, and the insertion shaft 4 is located in the sliding groove 5; to avoid jamming, the upper and lower support plates 1 can slide relative to each other.

[0022] The surface of the roller 2 is provided with a groove 6, and the support plate 1 is provided with a limiting block 7 that cooperates with the groove 6; by using the cooperation between the limiting block 7 and the groove 6, the position of the roller 2 is restricted to prevent the roller 2 from shifting.

[0023] The grooves 6 are evenly distributed on the surface of the roller 2; by using multiple grooves 6, the constraint on the roller 2 is increased, the occurrence of deviation is further reduced, and the safety of production is improved.

[0024] The end of the roller 2 is chamfered, and the side of the limiting block 7 fits into the chamfered surface of the roller 2; this makes the roller 2 and the limiting block 7 less prone to damage and extends their service life.

[0025] The end plate 3 on the bottom plate 12 is located on the outer side of the ends of the rollers 2 at both ends; it is offset from the end plate 3 on the top plate 11 to reduce friction.

[0026] The technical advantages of this invention are as follows: When the heat transfer oil storage tank changes temperature, the tank body undergoes lateral displacement, and the roller 2 rolls between the upper and lower support plates 1, thereby adapting to the expansion or contraction of the tank body. At the same time, the rolling support can also bear the vertical load of the heat transfer oil storage tank and transfer it to the lower structure. It can also withstand large vertical loads and horizontal forces. The support does not require more complex anti-corrosion measures, has a low maintenance rate, stable working performance, is durable, and is safe and reliable.

[0027] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
