Description

Technical Field

[0001] This application relates to the technical field of electric tracing band installation, and particularly to a heat tracing structure for the outer wall of a storage tank. Background Art

[0002] Storage tanks are generally heated by tracing bands. Currently, technicians usually directly lay the tracing bands on the outer wall of the storage tank and fix them with tape. During the operation, it is found that this electric tracing band laying method often requires two or more people to lay and fix at the same time, with a high dependence on manual labor and low laying efficiency. If the area of the storage tank is large, multiple circuits need to be laid, and the operation difficulty is relatively high. Moreover, during the use of electric tracing heat, the electric tracing bands exposed on the outer wall of the storage tank are extremely vulnerable to external physical damage. Over time, the electric tracing bands removed from the storage tank cannot be used again. Summary of the Utility Model

Among them, the head end of the tracing band installed in the lowermost heat conduction cloth is connected to a power supply, and the tail end of the tracing band installed in the uppermost heat conduction cloth is wrapped by the heat conduction layer.

[0032] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0033] An embodiment of the present utility model provides an external wall heat tracing structure for a storage tank. Please refer to Figures 1-5 . The external wall heat tracing structure for the storage tank includes a storage tank 1, a heat conduction layer, and a heat insulation layer 3.

[0034] Specifically,

[0035] The heat conduction layer is composed of at least one piece of heat conduction cloth 20 installed. A heat tracing belt 22 is installed in the heat conduction cloth 20. The heat tracing belt 22 can be serpentinely arranged in the heat conduction cloth 20 along the length direction of the heat conduction cloth, or can be serpentinely arranged in the heat conduction cloth 20 along the width direction of the heat conduction cloth. The tail end 221 of the heat tracing belt is inserted into the heat conduction cloth 20 from one side near the bottom end of the heat conduction cloth 20, and is serpentinely arranged in the heat conduction cloth 20 to the other side near the top end of the heat conduction cloth 20. At this time, the tail end 221 of the heat tracing belt can be pulled out of the heat conduction cloth 20, or the tail end 221 of the heat tracing belt can be wrapped in the heat conduction cloth 20; while the head end 220 of the heat tracing belt is exposed outside the heat conduction cloth 20. The above heat tracing belt 22 can be either a low-temperature heat tracing belt or a high-temperature MI type heat tracing belt.

[0036] The heat-conducting cloth 20 is provided to match the storage tank 1, that is, the length of the heat-conducting cloth 20 is equal to or slightly greater than the circumferential perimeter of the storage tank 1. The heat-conducting cloth 20 is wound around the outer wall of the storage tank. To ensure the fixed installation of the heat-conducting cloth 20 on the outer wall of the storage tank, cable ties 21 are used to fix the heat-conducting cloth 20 to the outer wall of the storage tank, and the cable ties 21 are made of steel. The cable ties can be directly tied to the outside of the heat-conducting cloth 20, or the cable ties 21 can be first inserted through the heat-conducting cloth 20. After the heat-conducting cloth 20 is wound around the outer wall of the storage tank, the heat-conducting cloth 20 is then tied tightly to the outer wall of the storage tank through the cable ties 21. Among them, the cable ties 21 inserted through the heat-conducting cloth 20 are arranged on both sides of the heat-conducting cloth 20.

[0037] When the width of the heat-conducting cloth 20 is less than the height of the storage tank 1, the heat-conducting cloth 20 can be wound around the outer wall of the storage tank in a way of splicing up and down, which is convenient and flexible to operate. The number of spliced heat-conducting cloths 20 is set to match the height of the storage tank, so that the storage tank 1 can achieve uniform heat preservation. Between two adjacent heat-conducting cloths 20 up and down: the tail end 221 of the heating tape provided on the lower heat-conducting cloth 20a and the head end 220 of the heating tape provided on the upper heat-conducting cloth 20b are connected through a socket plug 23, so that the two groups of heating tapes 20 up and down can be quickly connected in series. Among them, the head end 220 of the heating tape provided on the lowermost heat-conducting cloth 20 is connected to a power supply. The tail end 220 of the heating tape provided on the uppermost heat-conducting cloth 20 is wrapped inside the heat-conducting cloth 20.

[0038] When the width of the heat-conducting cloth 20 is equal to or greater than the height of the storage tank, after one heat-conducting cloth 20 is wound around the outer wall of the storage tank, the heat-conducting cloth 20 can be fixedly installed through the cable ties 21. The head end 220 of the heating tape provided on the heat-conducting cloth 20 is connected to a power supply, and the tail end 221 of the heating tape is wrapped inside the heat-conducting cloth 20.

[0039] The heat-insulating layer 3 is preferably laid on the outside of the heat-conducting layer to prevent the heat supplied by the heat-conducting layer to the storage tank 1 from dissipating. Preferably, the heat-insulating layer 3 is made of cotton. The heat-insulating layer 3 is fixed to the outside of the heat-conducting layer through a binding band 4. The binding band 4 can be made of steel wire.

[0040] Based on the above embodiments, the installation method of the present application is (taking the up-and-down splicing of two heat-conducting cloths 20 as an example):

[0041] After the lower heat-conducting cloth 20a is wound around the outer wall of the storage tank and tightly fixed with the cable ties 21, the upper heat-conducting cloth 20b is wound around the outer wall of the storage tank at a position close to the lower heat-conducting cloth 20a and tightly fixed with the cable ties 21. At this time, the tail end 221 of the heating tape provided on the lower heat-conducting cloth 20a and the head end 220 of the heating tape provided on the upper heat-conducting cloth 20b are connected through a socket plug 23. The head end 220 of the heating tape provided on the lower heat-conducting cloth 20a is powered by a power supply, and the tail end 221 of the heating tape provided on the upper heat-conducting cloth 20b is wrapped inside the heat-conducting cloth 20. Subsequently, after the heat-insulating layer 3 is laid on the outside of the heat-conducting layer, it is tightly tied with the binding band 4 to prevent the heat-insulating layer 3 from falling off.

[0042] Based on the above embodiments, the advantages of the present application are as follows:

[0043] Through the cable tie 21 and the socket-and-plug type plug 23, the rapid installation or disassembly of the heat-conducting cloth 20 on the outer wall of the storage tank can be realized, which increases the operation convenience. Among them, when installing the heat-conducting cloth, the number of the heat-conducting cloth 20 can be adapted according to the height of the storage tank 1, which is beneficial to the uniform heat tracing of the storage tank 1. Since the heating tape 22 is installed in the heat-conducting cloth 20, the heating tape 22 can be effectively prevented from being physically damaged by the outside world, and the disassembled heat-conducting layer can be reused again, saving costs. At the same time, arranging the heat-insulating layer 3 outside the heat-conducting layer is beneficial to preventing the heat of the storage tank 1 from dissipating.
