Description

Technical Field

[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and is widely used. Heat exchanger is an energy-saving device that realizes heat transfer between materials between two or more fluids at different temperatures. It transfers heat from a higher temperature fluid to a lower temperature fluid, so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. It is also one of the main equipment to improve energy utilization.

[0003] The problem with the prior art is that when the weather temperature is low, the temperature difference between the inside and outside of the shell of the existing heat exchanger is large. In order to prevent heat loss, an insulation layer is wrapped on the surface of the shell and fixed to it by glue. However, when the heat exchanger is maintained, it cannot be disassembled and can only be destroyed. After maintenance, the insulation layer is re-pasted, which increases the maintenance cost. In order to reduce the maintenance cost and heat loss at the same time, a heat exchanger with an insulation structure is proposed. When the heat exchange plate is maintained, the insulation partition can be easily disassembled while ensuring the insulation effect of the heat exchanger. Utility Model Content

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown, a heat exchanger with a thermal insulation structure provided by an embodiment of the utility model includes a placement plate 1, a protective plate 2, a thermal insulation partition 3, an insulation layer 4, a heat exchange plate 5 and a positioning block 6.

[0025] refer to Figure 4 The adjustment mechanism 8 includes a moving rod 801, a cross bar 802 and a fixed column 803. The front side of the moving rod 801 passes through the front side of the positioning block 6, and the rear side of the moving rod 801 passes through the interior of the positioning block 6. The rear side of the moving rod 801 is fixedly connected to the front side of the cross bar 802, and the top of the cross bar 802 is fixedly connected to the bottom of the fixed column 803. The fixed column 803 is used in conjunction with the positioning mechanism 9.

[0026] The above scheme is adopted: by setting up the adjustment mechanism 8, the movable rod 801 can be pulled, and the movable rod 801 drives the cross bar 802 to move, and the cross bar 802 drives the fixed column 803 to move forward. When adjusting the thermal insulation partition 3, it is convenient for the staff to operate and use it, and the operation process is simplified.

[0027] refer to Figure 4The positioning mechanism 9 includes a bent rod 901, a positioning rod 902 and a compression spring 903. The top of the fixed column 803 passes through the top of the bent rod 901. The bent rod 901 is movably connected to the inside of the positioning cavity 7 through a rotating shaft. The opposite sides of the two bent rods 901 are in contact with the opposite sides of the two positioning rods 902. The opposite sides of the two positioning rods 902 are fixedly connected to the left and right sides of the compression spring 903. The opposite sides of the two positioning rods 902 pass through the inside of the thermal insulation partition 3.

[0028] By adopting the above solution, by providing the positioning mechanism 9, the heat-insulating partition 3 can be stably fixed on the top of the placement plate 1 to prevent it from loosening during use and to ensure that it is stably fixed.

[0029] refer to Figure 4 and Figure 5 A fixing groove 10 is provided on the surface of the heat-insulating partition 3, and the positioning rod 902 is in close contact when plugging.

[0030] By adopting the above solution, by providing the fixing groove 10, the positioning rod 902 can be accurately inserted into the fixing groove 10 during plugging and fixing, so that it can be stably fixed and ensure a good heat insulation effect.

[0031] refer to Figure 4 A limiting groove 11 is opened inside the positioning cavity 7 , and the positioning rod 902 moves along the opening direction of the limiting groove 11 .

[0032] By adopting the above solution, by providing the limiting groove 11, the positioning rod 902 can move along the moving track provided by the limiting groove 11, thereby ensuring the normal use of the structure and preventing damage.

[0033] refer to Figure 4 A travel groove 12 is provided at the top of the curved rod 901 , and the travel groove 12 is used in conjunction with the fixed column 803 .

[0034] By adopting the above solution, by providing the travel groove 12, the moving direction and travel of the fixed column 803 can be limited when it moves, so as to prevent the fixed column 803 from exceeding the travel during use and causing structural damage.

[0036] By adopting the above solution, by providing the limiting rod 13 and the limiting groove 14 , the moving direction and stroke of the moving rod 801 can be limited, so that the moving rod 801 moves along the path set by the limiting groove 14 .

[0037] refer to Figure 5 The material of the thermal insulation partition 3 is rock wool board, and the material of the thermal insulation layer 4 is thermal insulation wool.

[0038] The above solution is adopted: by providing the heat-insulating partition 3 and the heat-insulating cotton, it is possible to reduce the heat loss when the heat exchanger is used, thereby improving the working efficiency of the heat exchanger.

[0039] The working principle of this utility model:

[0040] When in use, the moving rod 801 is pulled forward, and the moving rod 801 drives the cross bar 802 to move forward according to the moving trajectory provided by the limit groove 14, and the cross bar 802 drives the fixed column 803 to move forward, and the surface of the fixed column 803 squeezes the inner wall of the travel groove 12 so that the two bent rods 901 rotate to the opposite side with the rotating shaft as the center. During rotation, the surface of the bent rod 901 squeezes the surface of the positioning rod 902 so that the two positioning rods 902 move to the opposite side. The positioning rod 902 moves according to the moving trajectory provided by the limiting groove 11 and compresses the compression spring 903 at the same time. At this time, the thermal insulation partition 3 can be bent inward and then taken out, and the internal heat exchange plate 5 can be maintained to ensure the normal use of the equipment. After completion, the moving rod 801 is released, and the positioning rod 902 is reinserted into the interior of the fixed groove 10 due to the rebound force of the compression spring 903.

[0041] In summary: the heat exchanger with a thermal insulation structure, by arranging a placement plate 1, a protective plate 2, a thermal insulation partition 3, an insulation layer 4, a heat exchange plate 5, a positioning block 6, a positioning cavity 7, an adjustment mechanism 8, a moving rod 801, a cross bar 802, a fixing column 803, a positioning mechanism 9, a bending rod 901, a positioning rod 902, a compression spring 903, a fixing groove 10, a limiting groove 11, a travel groove 12, a limit rod 13 and a limit groove 14, solves the problem that when the weather temperature is low, the temperature difference between the inside and outside of the shell is large. In order to prevent heat loss, the existing heat exchanger is wrapped with an insulation layer on its surface and fixed with glue. However, when the heat exchanger is maintained, it cannot be disassembled and can only be destroyed. After maintenance, the insulation layer is re-pasted, which increases the maintenance cost. In order to reduce the maintenance cost and heat loss at the same time, a heat exchanger with a thermal insulation structure is proposed. When the heat exchanger plate is maintained, it is convenient to disassemble the thermal insulation partition while ensuring the thermal insulation effect of the heat exchanger.
