Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation structure technology, specifically relating to a thermal insulation structure for steel silos. Background Technology

[0002] In the warehousing industry, steel silos are widely used as important storage equipment for storing various goods such as grains, chemical raw materials, and building materials. However, traditional steel silos have many shortcomings in terms of insulation and temperature control, and these problems become increasingly prominent, especially during long-term use.

[0003] First, traditional steel silos typically employ a one-piece insulation design, with insulation material directly filled inside or outside the silo to form a fixed insulation layer. While this design provides some insulation, replacing the insulation material becomes extremely difficult once it is damaged or aged. Because the insulation layer is tightly connected to the silo body, maintenance requires extensive disassembly, which is not only time-consuming and labor-intensive but also increases maintenance costs. Furthermore, since the insulation material is difficult to replace in parts, if a problem occurs in one area, the entire insulation layer often needs to be removed, resulting in a significant waste of resources.

[0004] Secondly, traditional steel silos have significant shortcomings in temperature control. Especially in high-temperature environments, the internal temperature of a steel silo can rise rapidly, severely affecting the quality and stability of stored goods. To reduce the temperature, some steel silos use external water spraying or fan cooling methods, but these methods are not only limited in effectiveness but may also lead to increased humidity inside the silo, causing secondary damage to the stored goods, thus having certain limitations. Utility Model Content

[0005] The purpose of this utility model is to provide a steel silo insulation structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel silo insulation structure, comprising...

[0007] The steel silo body has insulation components installed on its inner wall, and several sets of aluminum alloy protective plates are installed inside the steel silo body to limit and fix the insulation components. The inner wall of the steel silo body has an installation structure to fix the insulation components and aluminum alloy protective plates.

[0008] A protective top is installed on the top of the steel silo body;

[0009] The aluminum alloy protective plate has a temperature control structure inside for temperature control.

[0010] Both the insulation component and the aluminum alloy protective plate have through holes inside. The installation structure includes several sets of bolts that are fixedly connected to the inner wall of the steel silo body. The bolts pass through the through holes inside the insulation component and the aluminum alloy protective plate. Nuts are detachably installed on the outside of the bolts. When the nuts are in contact with the side of the aluminum alloy protective plate, they limit and fix the aluminum alloy protective plate.

[0011] In one preferred embodiment, the insulation component includes several polyurethane foam layers that are attached to the inner wall of the steel silo body. A rock wool layer is fixedly connected to the side of the polyurethane foam layer away from the steel silo body, and a glass wool sandwich layer is fixedly connected to the side of the rock wool layer away from the polyurethane foam layer.

[0012] In a preferred embodiment, the glass wool core layer is bonded to the adjacent aluminum alloy protective plate, and the polyurethane foam layer, rock wool layer and glass wool core layer are bonded to the adjacent polyurethane foam layer, rock wool layer and glass wool core layer, respectively.

[0013] In a preferred embodiment, the temperature control structure includes a water inlet, which is disposed inside an aluminum alloy protective plate, and the shape of the water inlet is S-shaped.

[0014] In a preferred embodiment, the temperature control structure also includes a drain valve and a water inlet valve, both of which are installed on the side of the aluminum alloy protective plate and are connected to the water supply tank. The drain valve and the water inlet valve are both located at the same height on the side of the aluminum alloy protective plate.

[0015] In one preferred embodiment, a connecting pipe is detachably installed on the drain valve, and the end of the connecting pipe away from the drain valve is detachably installed on a nearby inlet valve at the same height.

[0016] In a preferred embodiment, the steel silo body is equipped with two conduits, which are respectively connected to an external water pump and a water tank. One conduit is connected to the inlet valve on the surface of the nearby aluminum alloy protective plate via a hose, and the other conduit is connected to the drain valve on the surface of the nearby aluminum alloy protective plate via a hose. When the water pump is working, the water inside the external water tank can circulate in all the water delivery channels.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model, by setting up an aluminum alloy protective plate and installation structure, allows operators to easily remove the aluminum alloy protective plate by simply rotating the nuts on the side of the corresponding aluminum alloy protective plate when local insulation components are damaged during long-term use, resulting in poor insulation performance. After removing the aluminum alloy protective plate, the insulation components on the back of the aluminum alloy protective plate can be replaced. The modular design means that each component can be disassembled and installed independently, without the need for large-scale disassembly of the entire insulation structure, which greatly shortens the repair time and reduces maintenance costs.

[0019] This invention, through the setting of a temperature control structure, installation structure, and connecting pipes, allows operators to adjust the water pump on the outer wall when the internal temperature of the steel silo becomes too high during use, affecting the storage of goods. The pump then delivers cooling water from the water tank to the corresponding conduit. With the cooperation of the connecting pipes, the cooling water circulates within the water delivery channel, fully utilizing the heat conduction properties of water to effectively absorb and remove the heat accumulated inside the steel silo, reducing the internal temperature and ensuring the stability and safety of the stored goods.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0028] Please see Figure 1-5 This utility model provides a steel silo insulation structure, including a steel silo body 1 and a protective top 2 installed on the top of the steel silo body 1. The inner wall of the steel silo body 1 is provided with insulation components 3, and the interior of the steel silo body 1 is provided with a plurality of aluminum alloy protective plates 4 for limiting and fixing the insulation components 3. The inner wall of the steel silo body 1 is provided with an installation structure 6 for fixing the insulation components 3 and the aluminum alloy protective plates 4. The interior of the aluminum alloy protective plates 4 is provided with a temperature control structure 5 for temperature control.

[0029] Both the insulation component 3 and the aluminum alloy protective plate 4 have through holes inside. The installation structure 6 includes several sets of bolts 601 that are fixedly connected to the inner wall of the steel silo body 1. The bolts 601 pass through the through holes inside the insulation component 3 and the aluminum alloy protective plate 4. Nuts 602 are detachably installed on the outside of the bolts 601. When the nuts 602 are in contact with the side of the aluminum alloy protective plate 4, they limit and fix the aluminum alloy protective plate 4.

[0030] Specifically, such as Figure 3 and 5 As shown, the insulation component 3 includes several polyurethane foam layers 301 attached to the inner wall of the steel silo body 1. A rock wool layer 302 is fixedly connected to the side of the polyurethane foam layer 301 away from the steel silo body 1. A glass wool sandwich layer 303 is fixedly connected to the side of the rock wool layer 302 away from the polyurethane foam layer 301. The glass wool sandwich layer 303 is attached to the nearby aluminum alloy protective plate 4. The polyurethane foam layer 301, rock wool layer 302, and glass wool sandwich layer 303 are respectively attached to the nearby polyurethane foam layer 301, rock wool layer 302, and glass wool sandwich layer 303. By setting the polyurethane foam layer 301, rock wool layer 302, and glass wool sandwich layer 303, polyurethane foam is a highly efficient insulation material that can significantly improve the insulation performance of the steel silo. The rock wool layer 302 has good heat insulation and fire resistance, and the glass wool sandwich layer 303 also has excellent heat insulation performance, thereby ensuring the insulation performance of the insulation structure.

[0031] Specifically, such as Figure 2 and 4As shown, the temperature control structure 5 includes a water supply tank 501, which is located inside the aluminum alloy protective plate 4 and is S-shaped. The temperature control structure 5 also includes a drain valve 502 and an inlet valve 503, both mounted on the side of the aluminum alloy protective plate 4 and connected to the water supply tank 501. Both valves are located at the same height on the side of the aluminum alloy protective plate 4. A connecting pipe 7 is detachably mounted on the drain valve 502. The end of pipe 7 away from drain valve 502 is detachably installed with the nearby inlet valve 503 at the same height. Two conduits 8 are installed on the steel silo body 1, and the two conduits 8 are respectively connected to the external water pump and water tank. One conduit 8 is connected to the inlet valve 503 on the surface of the nearby aluminum alloy protective plate 4 through a hose, and the other conduit 8 is connected to the drain valve 502 on the surface of the nearby aluminum alloy protective plate 4 through a hose. When the water pump is working, the water inside the external water tank can circulate inside all the water delivery tanks 501.

[0032] The working principle and usage process of this utility model: When the insulation structure is damaged during long-term use, resulting in poor insulation effect, the operator can directly rotate the nut 602 on the side of the corresponding aluminum alloy protective plate 4 to remove the aluminum alloy protective plate 4 and replace the insulation component 3 on the back of the aluminum alloy protective plate 4.

[0033] When the internal temperature of the steel silo body 1 becomes too high during use, affecting the storage of goods, the operator adjusts the water pump on the outer wall to deliver cooling water from the water tank to the corresponding conduit 8. With the cooperation of the connecting pipe 7, the cooling water flows through all the water delivery tanks 501 and is finally discharged into the external water tank through another conduit 8. When the cooling water flows, it absorbs the heat inside the steel silo body 1, thereby achieving a cooling effect.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
