Description

Technical Field

[0001] The utility model relates to a heat insulation structure, in particular to a heat insulation structure for a rolling support of a heat exchanger, and belongs to the technical field of heat exchanger support insulation equipment. Background Art

[0002] In the field of energy storage and power generation, the heat exchanger is one of the important components of the power generation system. With the continuous improvement of the power parameters of the unit, the design parameters of the heat exchanger are also getting higher and higher. The insulation problem faced by the high-temperature heat exchanger due to the high temperature is also becoming more and more obvious: the temperature of the support at the bottom of the heat exchanger and the contact position of the heat exchanger's basic structure will be limited, and generally cannot exceed the temperature specified in the standard.

[0003] However, due to the increase in the parameters of the heat exchanger, after the temperature of the support is transferred to the foundation structure, its temperature exceeds the bearing capacity of the existing foundation structure. After long-term operation, the materials of the existing foundation structure will become unsuitable, which forces the material selection of the foundation structure to be upgraded, thereby increasing the operating cost. If the existing foundation structure is used, the possibility of failure of the foundation structure increases, causing safety risks.

[0004] In summary, how to propose a heat insulation structure to address the above technical issues has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0005] The utility model aims at the above-mentioned deficiencies of the prior art and provides a heat insulation structure for a rolling support of a heat exchanger.

[0006] The technical scheme of the utility model is: a heat insulation structure for a rolling support of a heat exchanger, comprising a balanced pressure steel plate, a heat insulation pad and two roller pads.

[0007] The two roller pads are both fixedly connected to the upper surface of the balanced pressure steel plate to provide support for the rollers on the rolling support.

[0008] The balanced pressure steel plate is arranged on the heat insulation pad, the heat insulation pad is arranged on the basic structure of the rolling bearing, and the balanced pressure steel plate and the heat insulation pad are fixedly connected to the basic structure of the rolling bearing through anchor bolts.

[0009] The cross-sectional areas of the balanced pressure steel plate and the thermal insulation pad are both rectangular, the lengths of the balanced pressure steel plate and the thermal insulation pad are both greater than the span of the roller, and the length directions of the balanced pressure steel plate and the thermal insulation pad are parallel to the axis of the roller.

[0010] Compared with the prior art, the utility model has the following effects:

[0011] 1. The utility model has a simple structure, is easy to install, and has a good heat insulation effect. The good heat insulation performance of mica material is used to ensure that the basic structure of the rolling support 7 does not overheat.

[0012] 2. The raw materials of the utility model are easy to obtain and low in price. It can be installed on the original infrastructure and has strong adaptability, thus providing a guarantee for the safe and stable operation of the heat exchanger on the existing infrastructure.

[0018] In order to make the utility model objectives, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the implementation modes of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation modes of the utility model.

[0019] Specific implementation method 1: Combination Figures 1 to 4 The present embodiment is described. A heat insulation structure for a heat exchanger rolling support in the present embodiment includes a balanced pressure steel plate 2 , a heat insulation pad 3 and two roller pads 1 .

[0020] The two roller pads 1 are both fixedly connected to the upper surface of the balanced pressure steel plate 2 to provide support for the rollers on the rolling support 7 .

[0021] The balanced pressure steel plate 2 is arranged on the heat insulation pad 3 , the heat insulation pad 3 is arranged on the basic structure of the rolling bearing 7 , and the balanced pressure steel plate 2 and the heat insulation pad 3 are fixed to the basic structure of the rolling bearing 7 through anchor bolts 4 .

[0022] The cross-sectional areas of the balanced pressure steel plate 2 and the thermal insulation pad 3 are both rectangular, the lengths of the balanced pressure steel plate 2 and the thermal insulation pad 3 are both greater than the span of the roller, and the length directions of the balanced pressure steel plate 2 and the thermal insulation pad 3 are parallel to the axis of the roller.

[0023] In this embodiment, the anchor bolts 4 penetrate the balanced pressure steel plate 2 and the thermal insulation pad 3. Such an arrangement is conducive to preventing movement between the balanced pressure steel plate 2 and the thermal insulation pad 3.

[0024] In this embodiment, the cross-sectional area of ​​the balancing pressure steel plate 2 is larger than the cross-sectional area of ​​the roller pad 1 .

[0025] In the present embodiment, the roller on the rolling support 7 is in line contact with the roller pad 1, and the roller pad 1 transfers the gravity of the rolling support 7 to the balanced pressure steel plate 2. Since the roller pad 1 and the balanced pressure steel plate 2 are in surface-to-surface contact, the contact area is increased, so the pressure acting on the thermal insulation pad 3 is reduced, so that the thermal insulation pad 3 is more evenly stressed, thereby protecting the thermal insulation pad 3 from being crushed. If there is no combination of the roller pad 1 and the balanced pressure steel plate 2, the rolling support 7 is in direct contact with the thermal insulation pad 3, which can easily cause the thermal insulation pad 3 to be partially dented or crushed and fail, thereby affecting both the thermal insulation effect and the safe operation of the heat exchanger.

[0026] Specific implementation method 2: Combination Figures 1 to 4 To explain this embodiment, in this embodiment, the roller pad 1 is welded to the balance pressure steel plate 2. Other components and connection relationships are the same as those in the first embodiment.

[0027] Specific implementation method three: Combination Figures 1 to 4 To explain this embodiment, the material of the heat insulating pad 3 in this embodiment is mica. In this way, the good heat insulating performance of the mica material is utilized to ensure that the basic structure of the rolling bearing 7 does not overheat.

[0028] Furthermore, the thickness of the heat-insulating pad 3 is greater than the thickness of the balanced pressure steel plate 2 . This arrangement ensures that the heat-insulating pad 3 has sufficient strength.

[0029] The other components and connection relationships are the same as those in the first or second specific implementation.

[0030] Specific implementation method four: Combination Figures 1 to 4 To explain this embodiment, two washers 5 are installed on the anchor bolt 4 in this embodiment, one of which is arranged between the bolt head and the base structure of the rolling bearing 7, and the other is arranged between the balanced pressure steel plate 2 and the nut on the anchor bolt 4. Other components and connection relationships are the same as those of the first, second or third embodiments.

[0031] How it works

[0032] The heat insulation pad 3 , the balanced pressure steel plate 2 and the roller pad 1 are arranged in sequence on the basic structure of the rolling support 7 , and the roller pad 1 provides support for the roller on the rolling support 7 .

[0033] The roller pad 1 transfers the gravity of the rolling support 7 to the balanced pressure steel plate 2. Since the roller pad 1 and the balanced pressure steel plate 2 are in surface contact, the contact area is increased, so the pressure acting on the thermal insulation pad 3 is reduced, making the thermal insulation pad 3 more evenly stressed, thereby protecting the thermal insulation pad 3 from being crushed. The thermal insulation pad 3 made of mica is used to ensure that the basic structure of the rolling support 7 does not overheat.

[0034] The present invention has been disclosed as above in the form of a preferred embodiment, but it is not intended to limit the present invention. Any simple modification, equivalent changes and modifications made to the above implementation cases by any professional and technical personnel who do not deviate from the content of the technical solution of the present invention and based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
