Description

Technical Field

[0001] The utility model relates to the technical field of steam generators, in particular to a heat preservation and insulation structure of a steam generator. Background Art

[0002] Steam generator, also called steam heat source machine (commonly known as boiler), is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two parts: pot and furnace.

[0003] At present, the boiler in the steam generator is heated by an electric heating element arranged inside the pot. Since the curved plate of the boiler is generally made of metal, it is easy for the heat in the boiler to transfer outwards. The heat loss will cause the temperature in the boiler to drop, affecting the heating efficiency of the steam generator. As the heat is transferred outwards, it will also affect the control elements in the steam generator. Therefore, the existing boiler has a thermal insulation structure installed on the outer wall, but the thermal insulation structure is mostly directly tied to the boiler through fixing parts such as clamps. However, such a fixing method is easy to fall off after long-term use, thereby affecting the effect of the thermal insulation structure on the boiler. In addition, a water level gauge is provided on the side of the boiler. The water level gauge needs to be connected to the boiler through a pipe, and the thermal insulation structure sliding downward can easily cause extrusion damage to the pipe of the water level gauge, thereby causing the water in the boiler to flow out. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a steam generator heat insulation structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heat insulation structure of a steam generator is designed, comprising two coaxially arranged and arc-shaped arc plates, a semicircular bottom plate is installed at the bottom of the arc plate, and connecting plates are installed at the edges of both sides of the arc plate, and the connecting plates on the two arc plates are connected by fasteners, so that the two insulation shells are connected and merged to form a barrel-shaped structure with an open top;

[0006] At least three support tubes are vertically installed at the bottom of the base plate and are arranged at intervals along the edge of the base plate. A screw is built into the bottom of the support tube. A support base is rotatably installed on the bottom of the screw. A worm gear is connected to the top of the screw through a nut thread. The worm gear is rotatably installed on the bottom of the support tube. A worm is connected to the side of each worm gear, and two adjacent worm gears are coaxially connected through a connecting rod. A rotating shaft is connected to the outer end of the worm gear, and the rotating shaft is rotatably installed on the chassis, which is fixed to the base plate.

[0007] Preferably, a handle is connected to the end of one of the rotating shafts, and the handle is placed outside the chassis.

[0008] Preferably, a mounting seat is installed on the top of each supporting tube, and the mounting seat is fixed to the bottom of the base plate by fasteners.

[0009] Preferably, a second through hole is installed on the bottom plate and passes through the bottom plate, and the two second through holes correspond to each other. Two first through holes are installed on one side of the arc plate at intervals, and the first through holes pass through the side of the arc plate, and the first through holes on the two arc plates correspond to each other one by one.

[0010] Preferably, a second flange is installed at the top edge of each curved plate, and a top cover is provided above the curved plate. A first flange is installed at the bottom edge of the top cover, and the first flange is correspondingly connected to the second flange. A plurality of third through holes penetrating the top cover are installed on the top cover, and the third through holes on the two top covers correspond to each other one by one.

[0011] Preferably, the arc plate, bottom plate and top cover are all composed of an outer shell, an insulation layer and a thermal insulation layer. The outer shell is a metal support plate, the insulation layer is one of rock wool board, glass wool and foam board, and the thermal insulation layer is one of polyurethane board, polystyrene board and silicate wool board.

[0012] The design scheme proposed by the utility model has the following beneficial effects during application:

[0013] 1. The thermal insulation structure of the steam generator can adjust the height of the bottom plate and the curved plate through the screw, which can not only not affect the installation of the thermal insulation structure on the steam generator boiler, but also provide support for the bottom plate, the curved plate and the top cover after installation, so as to ensure the stability of the thermal insulation structure during use, so that the thermal insulation structure can always play a full role in thermal insulation for the boiler.

[0014] 2. The steam generator thermal insulation structure is easy to install on the steam generator boiler and to be subsequently disassembled and maintained by disassembling and assembling the curved plate, the bottom plate, and the top cover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 A steam generator thermal insulation structure comprises two coaxially arranged and arc-shaped arc plates 1, a semicircular bottom plate 23 is installed at the bottom of the arc plates 1; a second flange 18 is installed at the top edge of each arc plate 1, a top cover 16 is also provided above the arc plate 1, a first flange 17 is installed at the bottom edge of the top cover 16, the first flange 17 is connected to the second flange 18 correspondingly, a plurality of third through holes 19 penetrating the top cover 16 are installed on the top cover 16, and the third through holes 19 on the two top covers 16 correspond to each other one by one.

[0023] It should be noted that if Figure 5 As shown, the steam generator includes a casing (such as Figure 5 The casing is provided with a boiler chamber (such as Figure 5 The position indicated by the arrow B in the middle), a boiler is arranged in the boiler chamber (such as Figure 5 There is also a controller electrically connected to the boiler to control the boiler, and a sensor and a water level meter electrically connected to the controller to monitor the boiler temperature, air pressure, liquid level, etc.

[0024] Specifically, Figure 4 As shown, the arc plate 1, the bottom plate 23, and the top cover 16 are all composed of an outer shell 20, an insulating layer 21, and a heat-insulating layer 22. The outer shell 20 is a metal support plate, the insulating layer 21 is one of a rock wool board, glass wool, and a foam board, and the heat-insulating layer 22 is one of a polyurethane board, a polystyrene board, and a silicate wool board.

[0025] like Figure 1As shown, connecting plates 2 are installed at the edges of both sides of the arc plate 1, and the connecting plates 2 on the two arc plates 1 are connected by fasteners, so that the two insulation shells are connected and merged to form a barrel-shaped structure with an open top. In actual use, the fasteners are bolts or screws. After the arc plate 1 and the top cover 16 are docked on the boiler, a complete barrel-shaped thermal insulation structure can be formed and wrapped on the boiler by fastening with bolts or screws, which facilitates the installation and disassembly of the thermal insulation structure on the boiler.

[0026] A second through hole 15 is installed on the bottom plate 23 and passes through the bottom plate 23. The two second through holes 15 correspond to each other. Two first through holes 14 are installed on one side of the arc plate 1 and are arranged at intervals. The first through holes 14 pass through the side of the arc plate 1, and the first through holes 14 on the two arc plates 1 correspond to each other.

[0027] like Figure 3 As shown, at least three support tubes 3 are vertically installed at the bottom of the bottom plate 23 and are arranged at intervals along the edge of the bottom plate 23. A screw 4 is built into the bottom of the support tube 3. In actual use, the support tube 3 and the screw 4 are clearance-matched, so that the screw 4 can move freely and unrestricted in the support tube 3. A support base 7 is rotatably installed on the bottom of the screw 4, and a worm gear 5 is threadedly connected to the top of the screw 4 through a nut 6. The worm gear 5 is rotatably installed on the bottom of the support tube 3. A worm 8 is connected to the side of each worm gear 5, and two adjacent worm gears 8 are coaxially connected by a connecting rod 9. A rotating shaft 10 is connected to the end of the worm gear 8 on the outside, and the rotating shaft 10 is rotatably installed on the chassis 12. The chassis 12 is fixed to the bottom plate 23, so that when the rotating shaft 10 rotates, all the worm wheels 5 below the bottom plate 23 can be synchronously controlled to rotate; that is, after the arc plate 1 is placed in the boiler cavity, the rotating shaft 10 can be rotated, and the worm 8 is driven by the rotating shaft 10 to rotate, thereby controlling the rotation of the worm wheel 5, so as to adjust the rotation of the screw 4, thereby controlling the extension and contraction of the screw 4 in the support tube 3, and lifting the bottom plate 23, so that the bottom plate 23 fits on the bottom of the boiler, ensuring that the arc plate 1, the bottom plate 23, and the top cover 16 are close to the outer wall of the boiler, which has a heat preservation and heat insulation effect on the boiler. At the same time, the screw 4 and the support tube 3 support the bottom plate 23 and the arc plate 1, so as to improve the installation stability of the heat preservation and heat insulation structure on the boiler.

[0028] In order to facilitate the rotation of the rotating shaft 10 , a handle 11 is connected to one end of the rotating shaft 10 , and the handle 11 is placed outside the case 12 .

[0029] Specifically, when installing the thermal insulation structure, a curved plate 1 can be placed in the boiler cavity first, and the curved plate 1 can be placed against the outer wall of the boiler, and its bottom support base 7 can be placed on the bottom of the boiler cavity to provide support for the bottom plate 23. Then the handle 11 is turned to allow the screw 4 to rotate on the worm gear 5, so that the bottom plate 23 rises upward and the bottom plate 23 is placed against the bottom of the boiler. At this time, the boiler's sewage pipe passes through the second through hole 15, and then another curved plate 1 is taken and placed in the boiler cavity. Then the height of the bottom plate 23 is adjusted to a position consistent with the height of the previous curved plate 1, and then the curved plate 1 is placed against the outer wall on the other side of the boiler. At this time, the pipe on the boiler water level gauge passes through the first through hole 14, so that the two curved plates 1 can be completely closed, and then the fasteners are taken to fix the two curved plates 1 to ensure that the insulation layer 22 is close to the outer wall of the boiler, and finally the top cover 16 is taken and installed on the top of the curved plate 1.

[0030] It should be noted that if Figure 1 and Figure 2 As shown, since a plurality of third through holes 19 are provided on the top cover 16, the pressure gauge, the water inlet pipe, etc. can pass through the top cover 16 to ensure the normal installation and use of the boiler.

[0031] Further, such as Figure 3 As shown, a mounting seat 13 is installed on the top of each support tube 3, and the mounting seat 13 is fixed to the bottom of the base plate 23 by fasteners, so as to facilitate the installation of the support tube 3 on the base plate 23 and the disassembly and assembly between the arc plate 1, the base plate 23 and the support base 7, so that when the thermal insulation structure is maintained and repaired, the thermal insulation structure can be disassembled for separate replacement and repair.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
