Description

Technical Field

[0001] This utility model relates to the field of steel silo technology, and in particular to a corrosion-resistant and heat-insulating silo. Background Technology

[0002] Corrosion-resistant and heat-insulating silos are a new type of storage equipment that integrates corrosion resistance and heat insulation. They are specifically designed for storing temperature-sensitive materials. The silo body is made of special alloy materials or corrosion-resistant steel, which can effectively resist the erosion of harsh environments such as acids, alkalis and humidity, thereby significantly extending the service life of the equipment. At the same time, the silo wall is equipped with a high-efficiency heat insulation layer, which can stabilize the temperature inside the silo within a suitable range by blocking the exchange of heat between the inside and outside, thus avoiding the problem of materials clumping and deterioration due to excessive temperature changes. This provides a safe and stable storage environment for industrial, grain and food raw materials.

[0003] Although corrosion-resistant and insulated silos provide reliable protection for material management, the insulation layer in traditional silos is directly pasted or laid on the outside of the silo's steel plate. It relies on the integrity of the insulation layer itself to support the outer color plate. However, the insulation material will loosen, become hollow, or even fall off when there is vibration or temperature change, leading to local failure of the insulation layer. The existing solution is to fix the insulation layer and the outer color plate with Z-shaped steel and self-tapping screws. However, when replacing damaged insulation material or outer color plate, a large number of self-tapping screws and Z-shaped steel need to be disassembled, making the operation of repairing internal components of the device cumbersome and affecting the integrity and sealing of the silo. Utility Model Content

[0018] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a corrosion-resistant and heat-insulating silo, comprising an insulated outer barrel 1, a composite cylinder 2, and a silo top 4. The composite cylinder 2, as a component in direct contact with the material, is treated with anti-corrosion and high-temperature resistance. A fixing mechanism 3 is provided on the outside of the insulated outer barrel 1 to fix the heat-insulating components inside the insulated outer barrel 1 and facilitate replacement when the heat-insulating components are damaged. Multiple connecting plates 6 are fixedly connected to the inner wall of the insulated outer barrel 1 to connect the insulated outer barrel 1 and the composite cylinder 2. An anti-deformation mechanism 5 is provided at the top of the silo top 4 to enhance the deformation resistance of the device. A cover plate 9 is fixedly connected to the inner wall of the silo top 4. The cover plate 9 is equivalent to the composite cylinder 2 as a component in direct contact with the material. A monitoring mechanism 7 is provided inside the composite cylinder 2 to monitor the pressure and temperature inside the device. A sealing mechanism 8 is provided at the bottom of the silo top 4 to keep the connection between the insulated outer barrel 1 and the silo top 4 sealed. The fixing mechanism 3 includes multiple insulation sheets 301. The outer walls of the multiple insulation sheets 301 are fixedly connected to the inner wall of the outer insulation cylinder 1. A limiting top plate 302 is slidably connected to the top of the inner wall of the outer insulation cylinder 1. The limiting top plate 302 is used to prevent the insulation sheets 301 from detaching upwards and to facilitate the replacement of the insulation sheets 301. Buckles 303 are fixedly connected to the left and right sides of the bottom end of the limiting top plate 302. The top left and right sides of the outer insulation cylinder 1 are provided with slots 304. The buckles 303 engage with the slots 304, so that the limiting top plate 302 can both block the insulation sheets 301 in the space formed by the outer insulation cylinder 1 and the composite cylinder 2 and prevent material from contaminating the insulation sheets 301. An insulation bottom plate 305 is slidably connected to the bottom end of the inner wall of the outer insulation cylinder 1. The insulation bottom plate 305 can insulate the bottom end of the outer insulation cylinder 1. The base plate 305 serves as an insulation component. A rotating groove 306 is provided at the front end of the outer wall of the outer insulated outer barrel 1. The rotating groove 306 facilitates the removal and replacement of the insulation base plate 305. An arc-shaped baffle 307 is rotatably connected to the inner wall of the rotating groove 306. The arc-shaped baffle 307 is used to block the insulation base plate 305 in the rotating groove 306. A connecting piece 308 is fixedly connected to the outer wall of the arc-shaped baffle 307. A magnetic strip 309 is fixedly connected to the right end of the outer insulated barrel 1. The connecting piece 308 is an iron object and can form a magnetic connection with the magnetic strip 309, thereby fixing the position of the arc-shaped baffle 307. A connecting component 310 is provided on the outer wall of the outer insulated barrel 1. The connecting component 310 is used to connect the outer insulated barrel 1 and the top of the bin 4. A fixing component 311 is provided on the outer wall of the outer insulated barrel 1. The fixing component 311 is used to fix the position of the insulation piece 301. The connecting component 310 includes two locking lugs 3101. The adjacent sides of the two locking lugs 3101 are fixedly connected to the front and rear ends of the top of the bin 4. The front and rear ends of the outer wall of the outer wall of the heat-insulating outer barrel 1 are fixedly connected with buckles 3102. The outer wall of the heat-insulating outer barrel 1 and the top of the bin 4 are fixed by the locking lugs 3101 and the buckles 3102. The top of the bin 4 and the cover plate 9 are integral structures with heat-insulating components between them. When the heat-insulating components in the top of the bin 4 are damaged, the top of the bin 4 can be directly replaced by using the convenience of the fixing component 311. The fixing component 311 includes multiple bolts 3111. The outer walls of the multiple bolts 3111 are threaded to the outer wall of the outer wall of the heat-insulating outer barrel 1. The outer wall of the heat-insulating outer barrel 1 has multiple threaded grooves 3112. The bolts 3111 enter the threaded grooves 3112 and penetrate the heat-insulating sheet 301 and insert part of the composite cylinder 2, thereby fixing the position of the heat-insulating sheet 301. Specifically, when installing the insulation sheet 301, first slide the insulation sheet 301 into the gap between the outer insulation barrel 1 and the composite cylinder 2, screw in a small number of bolts 3111 to penetrate the insulation sheet 301 and partially insert it into the composite cylinder 2, thereby fixing the position of the insulation sheet 301. Then, slide the insulation base plate 305 from the rotating groove 306 into the bottom of the inner wall of the outer insulation barrel 1, rotate the arc-shaped baffle 307 to close the rotating groove 306, and magnetically fix the connecting piece 308 and the magnetic strip 309. Then, slide the limiting top plate 302 into the top of the outer barrel, so that the buckle 303 is engaged with the slot 304, completing the limiting of the top of the insulation sheet 301. Finally, place the top of the bin 4 on the outer barrel. At the top of the outer barrel 1, the locking lug 3101 is connected to the locking buckle 3102, which fixes the outer barrel 1 to the top of the silo 4. When replacing the insulation sheet 301, the locking buckle 3102 is released to remove the top of the silo 4, the buckle 303 is pressed to pull out the limiting top plate 302, and the old insulation sheet 301 can be pulled out by unscrewing the bolt 3111. When replacing the insulation bottom plate 305, the arc-shaped baffle 307 is opened, the old plate is pulled out from the rotating groove 306 and the new plate is inserted, and then the arc-shaped baffle 307 is reset. This makes it possible to replace the insulation components without disassembling a large number of parts. The overall operation is simple and quick, and the integrity and sealing of the silo are ensured, preventing the insulation layer from failing due to loosening.

[0019] Reference Figure 2 , Figure 3 and Figure 5 The anti-deformation mechanism 5 includes multiple reinforcing ribs 501, which are used to increase the structural strength of the outer insulation tank 1. The adjacent sides of the multiple reinforcing ribs 501 are fixedly connected to the outer wall of the outer insulation tank 1. The bottom of the inner wall of the composite cylinder 2 is fixedly connected to a gradient base 502, which is used to increase the structural strength of the inner wall of the composite cylinder 2. The top of the silo top 4 is fixedly connected to multiple inclined beams 503, which are reinforcing ribs. The top of the silo top 4 is fixedly connected to two annular reinforcing strips 504, which are respectively connected to the two ends of the inclined beams 503. The whole is fixedly connected to the top of the silo top 4, which can enhance the structural strength of the silo top 4. The top of the silo top 4 is provided with a pressure regulating hole 505, which is used to regulate the pressure inside the device. The inner wall of the pressure regulating hole 505 is fixedly connected to a pressure relief valve 506, which is used to reduce the pressure inside the device. Specifically, during installation, the reinforcing ribs 501 are first welded and fixed evenly along the outer wall of the insulated outer barrel 1 to enhance the outer barrel's resistance to deformation. Then, a gradient base 502 is welded to the bottom of the inner wall of the composite cylinder 2 to improve the load-bearing strength of the bottom through the thickness gradient structure. The multiple inclined beams 503 welded to the top of the silo roof 4 are distributed radially. Two annular reinforcing strips 504 are then welded to both ends of the multiple inclined beams 503 to form a mesh support structure, enhancing the overall strength of the silo roof 4. Finally, a pressure regulating hole 505 is opened at a preset position on the silo roof 4, and a pressure relief valve 506 is installed and fixed in the hole. This allows the reinforcing ribs 501 to disperse lateral pressure, while the inclined beams 503 and annular reinforcing strips 504 can resist the pressure generated by snow accumulation and strong winds on the silo roof 4. The pressure relief valve 506 can automatically release air through the pressure regulating hole 505, ensuring the overall resistance to deformation of the device.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The monitoring mechanism 7 includes multiple pressure sensors 701, which are used to monitor the pressure at various points within the device. The outer walls of the multiple pressure sensors 701 are fixedly connected to the inner wall of the composite cylinder 2. Multiple temperature sensors 702 are fixedly connected to the inner wall of the composite cylinder 2, which are used to monitor the temperature at various points within the device. The sealing mechanism 8 includes a rubber gasket 801, the bottom end of which is fixedly connected to the top of the limiting top plate 302. A sealing groove 802 is formed at the bottom end of the top of the silo 4. The rubber gasket 801 and the sealing groove 802 are connected. 02 Sliding connection reduces gas flow. The outer wall of the heat-insulating outer barrel 1 has multiple hidden grooves 10 for hiding bolts 3111. Each bolt 3111 has a cross groove 3113 on the opposite side, which makes it easy to access the bolts 3111. A buzzer 11 is fixedly connected to the right end of the outer wall of the heat-insulating outer barrel 1. The buzzer 11 can sound an alarm when the device malfunctions. A guardrail 12 is fixedly connected to the right end of the outer wall of the heat-insulating outer barrel 1 to protect the buzzer 11. Specifically, during installation, multiple pressure sensors 701 and temperature sensors 702 are uniformly fixed to the inner wall of the composite cylinder 2 to monitor the pressure and temperature at various points inside the chamber in real time. A rubber pad 801 is fixed to the top of the limiting top plate 302, and a sealing groove 802 is opened at the bottom of the chamber top 4 to allow the two to slide together to form a sealed structure, reducing gas flow. A hidden groove 10 is opened on the outer wall of the insulation outer barrel 1, so that the bolt 3111 is hidden after installation. The cross groove 3113 opened at the top of the bolt 3111 facilitates the use of tools. Finally, a buzzer 11 is fixed to the right end of the insulation outer barrel 1 and a protective railing 12 is installed for protection. During the use of the device, when the sensors detect abnormal conditions, the buzzer 11 will sound an alarm. During maintenance, the bolt 3111 is tightened through the cross groove 3113, and the hidden groove 10 and the sealing structure ensure the sealing and aesthetics of the entire device during operation. Finally, the protective railing 12 prevents the buzzer 11 from being damaged.

[0021] Working principle: When installing the insulation sheet 301, the insulation sheet 301 is partially fixed by the bolts 3111, while forming a double limit with the composite cylinder 2. The top is fully fixed by the buckle 303 connected to the limiting top plate 302 and the slot 304. The bottom of the inner wall of the insulation outer barrel 1 is slid into the space formed by the insulation bottom plate 305 through the rotating groove 306, and then locked by the magnetic attraction effect formed by the arc baffle 307, the connecting piece 308 and the magnetic strip 309, ensuring the tightness of the bottom space. The sealing process completes the fixation of the insulation base plate 305, thereby preventing the insulation components from loosening. When replacing the insulation components in the device, it is only necessary to disconnect the connection of the top of the silo 4, then pull out the limiting top plate 302 and unscrew a few bolts 3111 to replace the insulation sheet 301. The insulation base plate 305 can be directly replaced from the rotating groove 306 by rotating the arc baffle 307. This reduces the number of fixing components, avoids the disassembly of a large number of fixing parts and fixing nails, simplifies the replacement process, and maintains the airtightness and integrity of the silo body to prevent the insulation components from failing due to loosening. Furthermore, the reinforcing ribs 501 are uniformly welded along the outer wall of the insulated outer barrel 1 to form vertical support, thereby dispersing the lateral pressure to the entire barrel body and reducing local deformation of the device. The gradient base 502 at the bottom of the composite barrel 2, through its thickness gradient design, avoids deformation caused by pressure concentration. The radial inclined beams 503 and the annular reinforcing strips 504 on the top of the silo 4 form a mesh structure, allowing the inclined beams 503 to bear the longitudinal pressure and the annular reinforcing strips 504 to reduce the radial tension. The two work together to resist the pressure outside the top of the silo 4. Finally, the pressure regulating hole 505, in conjunction with the pressure relief valve 506, automatically opens to release air when the pressure of the device is too high, balancing the internal and external air pressure and preventing structural deformation caused by excessive pressure. The device strengthens the barrel body with the reinforcing ribs 501, stabilizes the bottom with the gradient base 502, and enhances the structural strength of the top of the silo 4 with the inclined beams 503 and the annular reinforcing strips 504, thus ensuring the overall deformation resistance of the device.
