Description

Technical Field

[0001] This utility model relates to the technical field of steam generator equipment, and in particular to a furnace body for a steam generator. Background Technology

[0002] In the existing technology, the water volume of steam generators must not exceed the corresponding standard value in order to meet the national standards. Currently, steam generators on the market are usually cylindrical, with an assembly port on the side of the cylindrical furnace body. The electric heating tube is inserted into the furnace body through the assembly port for heating. However, the diameter of the cylindrical steam generator is limited, and it is impossible to assemble electric heating tubes with longer lengths, resulting in relatively poor heating efficiency. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a steam generator furnace body that reduces the height and width of the steam generator, while meeting the national standard water volume, and extends the length in the front and back directions, making it suitable for longer electric heating tubes and achieving faster heating speed.

[0004] This utility model discloses a furnace body for a steam generator, including a furnace body with a water storage chamber. The furnace body is provided with an assembly port for the inlet and outlet of a heating element. The furnace body is provided with a first pipe for steam outlet, a second pipe for installing a safety valve, a third pipe for installing a water level electrode, and a fourth pipe for installing a pressure gauge. The furnace body is also provided with a water level gauge and a water pipe. The characteristic feature is that the cross-section of the furnace body is a long strip-shaped cross-section, and the assembly port is located on one side of the furnace body. When the heating element is assembled onto the furnace body, the heating element is arranged along the length direction of the long strip-shaped cross-section.

[0005] A further feature of this invention is that at least two assembly openings are spaced apart along the vertical direction.

[0006] A further feature of this invention is that the bottom of the furnace body is provided with a support foot, the water pipe is located at the bottom of the furnace body, and the support foot is provided with a clearance groove for the water supply pipe to pass through and avoid.

[0007] A further feature of this invention is that the furnace body is also provided with reinforcing ribs, which are supported on the front and rear side walls of the furnace body.

[0008] A further feature of this invention is that the bottom of the support leg is bent to form a fixing plate, and the fixing plate is also provided with a locking hole.

[0009] A further feature of this invention is that the top and bottom chamfers of the furnace body are curved.

[0010] The beneficial effects of this utility model are: the furnace body has a long strip cross-section, which makes its length in the front and back directions longer, making it suitable for longer electric heating tubes and faster heating speed. Attached Figure Description

[0015] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] This utility model discloses a steam generator furnace body, including a furnace body 1 with a water storage chamber 11. The furnace body 1 is provided with an assembly port 2 for the inlet and outlet of the heating element. The furnace body 1 is provided with a first pipe 3 for venting steam, a second pipe 4 for installing a safety valve, a third pipe 5 for installing a water level electrode, and a fourth pipe 6 for installing a pressure gauge (the first pipe 3, second pipe 4, third pipe 5, and fourth pipe 6 are preferably located at the top of the furnace body 1), a first gas storage tank, and a water level gauge 7 and a water pipe 8. In this utility model embodiment, the cross-section of the furnace body 1 is a long strip cross-section 9 (most preferably a rectangular cross-section), and the assembly port 2 is located on one side of the furnace body 1. When the heating element is assembled onto the furnace body 1, the heating element is arranged along the length direction of the long strip cross-section 9, which reduces the height and width of the steam generator and extends its length in the front-to-back direction. Under the condition of meeting the national standard water volume, it can be used for longer heating elements and the heating speed is faster.

[0018] The assembly port 2 is provided at least two at intervals along the vertical direction. By providing multiple assembly ports 2, multiple heating tubes can be installed, which can further improve the efficiency of boiling water.

[0019] The furnace body 1 is provided with a support foot 10 at the bottom. The water pipe 8 is located at the bottom of the furnace body 1, and the support foot 10 is provided with a relief groove 20 through which the water supply pipe 8 passes. This avoids the furnace body 1 from directly contacting the ground and facilitates the installation and layout of the water pipe 8. The relief groove 20 can save materials and facilitate the layout of the water pipe 8. The water pipe 8 is used for sewage discharge and water inlet, and can be connected by a tee fitting and a valve.

[0020] The furnace body 1 is also provided with reinforcing ribs 30, which are supported on the front and rear side walls of the furnace body 1. This can increase the structural rigidity of the furnace body, and increase its stability and service life.

[0021] The bottom of the support foot 10 is bent to form a fixing plate 40. The fixing plate 40 is also provided with a locking hole 50. The bent fixing plate 40 can increase the contact area and increase the friction to achieve the anti-slip effect. In addition, the locking hole 50 can also be used for bolts to pass through for locking, further improving stability.

[0022] The top and bottom corners of the furnace body 1 are beveled in an arc shape to increase structural strength and reduce scale buildup.
