Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, and more particularly to a storage tank insulation component. Background Art

[0002] Under high temperature conditions, the dichloromethane in the storage tank will convert from liquid to gaseous phase, and the gaseous dichloromethane will be discharged from the breathing valve at the top of the storage tank, resulting in dichloromethane loss. In order to reduce the loss of dichloromethane, the dichloromethane can be cooled. Some existing storage tanks have insulation functions during production, and can cool the materials in the storage tank and maintain a low temperature by flowing a low-temperature medium in the insulation layer. However, for general storage tanks that have been put into use, it is difficult to add heat exchange pipes wrapped around the storage tank, because the storage tank cannot be directly exposed to open flames during use and the tank body cannot be damaged. If the storage tank is emptied, it will have a great impact on production. Therefore, modification takes time, and there is no other place to store the materials in the storage tank. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiency in the prior art that old storage tanks do not have a heat preservation function, and to provide a storage tank heat preservation component that can be installed on a storage tank and can keep the material in the storage tank warm.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A storage tank insulation assembly is provided, comprising a plurality of support frames for being arranged around a storage tank and a heat exchange tube for being wound around the storage tank; the heat exchange tube is spiral-shaped; the support frame comprises a frame body and a plurality of connecting arms mounted on the frame body and distributed in a vertical direction, the ends of the connecting arms being connected to the heat exchange tubes, and the connecting arms located at different heights being connected to the heat exchange tubes at corresponding heights, respectively.

[0006] In the above technical solution, the heat exchange tube is wound around the lower part of the storage tank in a spiral shape, the support frame is arranged around the storage tank and fixed, and the connecting arm is connected to the heat exchange tube through a fixed connection or a tube bundle. Since the support frame is fixed, the heat exchange tube can be supported by the support frame to keep the heat exchange tube in contact with the storage tank. The inlet and outlet of the heat exchange tube are connected to the insulation fluid supply device. When insulation is required, the insulation fluid supply device injects insulation fluid into the heat exchange tube. Since the heat exchange tube remains in contact with the storage tank, it can exchange heat with the storage tank, thereby cooling the material in the storage tank and maintaining a lower temperature. When fixing the heat exchange tube, there is no need to make any modification operations to the storage tank. The storage tank will not directly come into contact with open flames and will not damage the tank body, so the storage tank can always be in use.

[0007] Furthermore, the system includes an annular base for surrounding the outer ring of the storage tank, and the frames are mounted on the annular base and are evenly spaced around the circumference. The annular base is fixed to the ground via anchor bolts, and the frames are connected to the annular base via fasteners, thereby achieving an effect that the frames can be easily assembled and disassembled.

[0008] Furthermore, the frame includes a base and a vertical rod mounted on the base, with the connecting arms mounted on the vertical rod. The base is provided with a waist-shaped hole, the length of which is parallel to the radial direction of the annular base. The base is secured to the annular base via fasteners passing through the waist-shaped hole. Changing the mounting position of the waist-shaped hole allows the frame to be positioned on the annular base, allowing the frame to be moved away from or closer to the storage tank, allowing the support frame to better fit the heat exchange tubes to the tank.

[0009] Furthermore, the connecting arm is welded to the heat exchange tube. The welding method allows the outer surface of the heat exchange tube to directly fit the outer surface of the storage tank, resulting in a good heat exchange effect and a more stable connection.

[0010] Furthermore, the end of the connecting arm is provided with an L-shaped connecting portion, which is welded to the bottom and outer side of the heat exchange tube. The L-shaped connecting portion can support the heat exchange tube and also limit the outward expansion or deformation of the heat exchange tube, thereby having a better fixing effect on the heat exchange tube.

[0011] Furthermore, the winding height of the heat exchange tube is at least half of the liquid level in the storage tank. Having sufficient heat exchange area allows the liquid phase to be in a relatively low temperature state.

[0012] Furthermore, a housing is installed between two adjacent support frames. The housing is used to enclose the heat exchange tubes, and an insulation layer is provided between the housing and the heat exchange tubes. The housing and support frames surround the storage tank and the heat exchange tubes, and insulation material is then filled between the housing and the storage tank, thereby forming an insulation layer between the housing and the heat exchange tubes. The insulation layer can reduce heat exchange between the heat exchange tubes and the outside atmosphere, allowing the heat exchange tubes to better insulate the storage tank. The installation of the housing does not affect the use of the storage tank and can be completed while the tank is in use.

[0013] Furthermore, the shell is formed by splicing a plurality of metal plates, and the original staircase on the storage tank can be avoided during the splicing.

[0014] Furthermore, the shell is welded to the frame, and the shell is connected to the vertical rod by welding, so that there is as little gap as possible between the shell and the support frame, thereby enhancing the heat preservation effect.

[0015] Furthermore, a cover portion is provided on the top of the shell, and the cover portion is adapted to fit the outer surface of the storage tank. The cover portion further surrounds the storage tank, isolating the external environment and the insulation layer, thereby further enhancing the insulation effect.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the storage tank insulation component of the present invention can be directly installed on the existing storage tank without the need to modify the storage tank and can allow the storage tank to be used normally. It can also enable the storage tank to increase the cooling and insulation functions of the liquid phase material, so that the material in the storage tank can maintain a lower temperature and reduce the loss caused by conversion to the gas phase.

[0023] Example 1

[0024] This embodiment is the first embodiment of a storage tank insulation component. Figure 1 As shown, the apparatus comprises an annular base 300 for surrounding the outer circumference of a storage tank, a plurality of support frames 100 for being arranged around the storage tank, and a heat exchange tube 200 for being wound around the storage tank; the heat exchange tube 200 is spiral-shaped; the support frame 100 comprises a frame body 110 and a plurality of connecting arms 120 mounted on the frame body 110 and distributed vertically. The frame body 110 is mounted on the annular base 300 and distributed equidistantly around the circumference. The ends of the connecting arms 120 are all connected to the heat exchange tube 200, and the connecting arms 120 located at different heights are connected to the heat exchange tube 200 at corresponding heights.

[0025] In this embodiment, the annular base 300 is divided into at least two sections for easy arrangement around the storage tank, and each section is connected to the ground. The two sections of the annular base 300 can be connected by fasteners or simply assembled together.

[0026] In this embodiment, the frame 110 includes a base 111 and a vertical rod 112 mounted on the base 111. The connecting arms 120 are each mounted on the vertical rod 112. The base 111 is provided with a waist-shaped hole, the length of which is parallel to the radial direction of the annular base 300. The base 111 is fixed to the annular base 300 via fasteners passing through the waist-shaped hole. Changing the installation position of the waist-shaped hole can adjust the position of the frame 110 on the annular base 300, thereby moving the frame 110 away from or closer to the storage tank, allowing the support frame 100 to better fit the heat exchange tube 200 to the storage tank. If the base 111 is directly connected to the ground, anchor bolts are generally used. If the number of support frames 100 is to be changed, the anchor bolts need to be re-installed. If the number is to be reduced, the anchor bolts need to be ground flat, which is not very convenient for assembly and disassembly.

[0027] In this embodiment, the connecting arm 120 is welded to the heat exchange tube 200. The welding method allows the outer surface of the heat exchange tube 200 to directly adhere to the outer surface of the storage tank, which has a good heat exchange effect and a more stable connection.

[0028] like Figure 2 As shown, the end of the connecting arm 120 is provided with an L-shaped connecting portion 121, which is welded to the bottom and outer side surfaces of the heat exchange tube 200. The L-shaped connecting portion 121 can support the heat exchange tube 200 and also limit the outward expansion or deformation of the heat exchange tube 200, thereby providing a better fixation effect on the heat exchange tube 200.

[0029] The winding height of the heat exchange tube 200 is at least half of the liquid level in the storage tank. The sufficient heat exchange area allows the liquid phase to be kept at a lower temperature.

[0030] The working principle of the storage tank insulation assembly of this embodiment is as follows:

[0031] In the above technical solution, the heat exchange tube 200 is wound around the lower part of the storage tank in a spiral shape, the support frame 100 is arranged around the storage tank and fixed on the annular base 300, and the L-shaped connection portion 121 at the end of the connecting arm 120 is welded to the heat exchange tube 200 to support and fix the position of the heat exchange tube 200. Since the support frame 100 is fixed, the heat exchange tube 200 can be supported by the support frame 100 to keep the heat exchange tube 200 in contact with the storage tank. The inlet and outlet of the heat exchange tube 200 are connected to the insulation fluid supply device. When insulation is required, the insulation fluid supply device injects insulation fluid into the heat exchange tube 200. Since the heat exchange tube 200 remains in contact with the storage tank, it can exchange heat with the storage tank, thereby cooling the material in the storage tank and maintaining a lower temperature. When fixing the heat exchange tube 200, there is no need to make any modification to the storage tank, the storage tank will not be directly exposed to open flames and the tank body will not be damaged, so the storage tank can be kept in use.

[0032] The beneficial effects of this embodiment are as follows: the storage tank insulation component can be directly installed on the existing storage tank without the need to modify the storage tank and can allow the storage tank to be used normally. It can also allow the storage tank to increase the cooling and insulation functions of the liquid phase material, so that the material in the storage tank can maintain a lower temperature and reduce the loss caused by conversion to the gas phase.

[0033] In this embodiment, the L-shaped connection portion 121 can also be connected to the heat exchange tube 200 by bonding, but the connection strength is not as good as welding. However, during installation, bonding is simpler and safer than welding.

[0034] In this embodiment, since the heat exchange tube 200 is spiral, the height of the heat exchange tube 200 at different positions is different. In order to allow the connecting arm 120 to support the heat exchange tube 200 at different positions, the connecting arm 120 is connected to the frame 110 through fasteners, and the frame 110 is provided with corresponding waist-shaped holes. The height of the connecting arm 120 is adjusted by changing the connection position of the connecting arm 120 and the frame 110, so that when the support frame 100 is placed in different positions, only the height of the connecting arm 120 needs to be changed, thereby realizing the universality of the support frame 100.

[0035] In another embodiment, the connecting arm 120 is welded to the frame 110 .

[0036] Example 2

[0037] This embodiment is the second embodiment of the storage tank insulation component. Figure 3 As shown, it includes multiple support frames 100 for arrangement around a storage tank and heat exchange tubes 200 for winding around the storage tank; the heat exchange tubes 200 are spiral-shaped; the support frame 100 includes a frame body 110 and multiple connecting arms 120 mounted on the frame body 110 and distributed in a vertical direction. The ends of the connecting arms 120 are all connected to the heat exchange tubes 200, and the connecting arms 120 located at different heights are connected to the heat exchange tubes 200 at corresponding heights. A shell 400 is installed between two adjacent support frames 100. The shell 400 is used to wrap the heat exchange tubes 200, and an insulation layer is provided between the shell 400 and the heat exchange tubes 200.

[0038] The shell 400 and the frame 110 are connected by fasteners, so that there is as little gap as possible between the shell 400 and the support frame 100, thereby enhancing the heat preservation effect.

[0039] The working principle of this embodiment is as follows: the heat exchange tube 200 is wound around the lower part of the storage tank in a spiral shape, the support frame 100 is arranged around the storage tank and fixed, and the connecting arm 120 is connected to the heat exchange tube 200 through a fixed connection or tube bundle. Since the support frame 100 is fixed, the heat exchange tube 200 can be supported by the support frame 100, so that the heat exchange tube 200 remains in contact with the storage tank. The inlet and outlet of the heat exchange tube 200 are connected to the insulation fluid supply device. When insulation is required, the insulation fluid supply device injects insulation fluid into the heat exchange tube 200. Since the heat exchange tube 200 remains in contact with the storage tank, it can exchange heat with the storage tank, thereby cooling the material in the storage tank and maintaining a low temperature. When fixing the heat exchange tube 200, no modification operations need to be made to the storage tank. The storage tank will not directly come into contact with open flames and will not be damaged, so the storage tank can be kept in use at all times. The shell 400 and support frame 100 surround the storage tank and heat exchange tubes 200, and insulation material is then filled between the shell 400 and the storage tank, thereby forming an insulation layer between the shell 400 and the heat exchange tubes 200. The installation of the shell 400 will not affect the use of the storage tank and can be completed while the storage tank is in use.

[0040] This embodiment has the following advantages over the first embodiment: the storage tank insulation assembly of the present invention can be directly installed on an existing storage tank without requiring modification, allowing the tank to function normally. It also provides the tank with enhanced cooling and heat preservation capabilities for liquid-phase materials, maintaining a relatively low temperature for the materials within the tank and reducing losses caused by conversion to the gas phase. The insulation layer reduces heat exchange between the heat exchange tube 200 and the outside atmosphere, improving the heat insulation effect of the heat exchange tube 200 on the tank.

[0041] Example 3

[0042] This embodiment is the third embodiment of the storage tank insulation assembly. This embodiment is similar to the first embodiment, except that Figure 3 As shown, a shell 400 is installed between two adjacent support frames 100. The shell 400 is used to wrap the heat exchange tube 200, and an insulation layer is provided between the shell 400 and the heat exchange tube 200. The shell 400 and the support frame 100 surround the storage tank and the heat exchange tube 200, and then the insulation material is filled between the shell 400 and the storage tank, thereby forming an insulation layer between the shell 400 and the heat exchange tube 200. The insulation layer can reduce the heat exchange between the heat exchange tube 200 and the outside atmosphere, allowing the heat exchange tube 200 to better insulate the storage tank. The installation of the shell 400 will not affect the use of the storage tank, and the installation can be completed when the storage tank is in use.

[0043] The outer surface of the storage tank has a staircase, so in this embodiment, the shell 400 is spliced ​​together by multiple metal plates, and the original staircase on the storage tank can be avoided during splicing.

[0044] In this embodiment, the shell 400 is welded to the frame 110, and the shell 400 is connected to the vertical rod 112 by welding, so that there is as little gap as possible between the shell 400 and the support frame 100, thereby enhancing the heat preservation effect.

[0045] The top of the housing 400 is further provided with a cover portion 410, which is used to fit the outer surface of the storage tank. The cover portion 410 further surrounds the storage tank, isolating the external environment and the insulation layer, and further improving the insulation effect.

[0046] In this embodiment, the shell 400 is made of aluminum, and the heat-insulating material is heat-insulating cotton.

[0047] The working principle of this embodiment is as follows: the shell 400 and support frame 100 surround the storage tank and heat exchange tubes 200. Insulation material is then filled between the shell 400 and the storage tank, forming an insulation layer between the shell 400 and the heat exchange tubes 200. This insulation layer reduces heat exchange between the heat exchange tubes 200 and the outside atmosphere, allowing the heat exchange tubes 200 to better insulate the storage tank. The installation of the shell 400 does not affect the use of the storage tank and can be completed while the tank is in use.

In order to make the description concise, not all possible combinations of the above-mentioned technical features are described.
