Description

Technical Field

[0001] The utility model relates to the technical field of economizer heat exchange tubes, in particular to an economizer heat exchange tube convenient for installation. Background Technique

[0002] An economizer is a device installed at the lower part of the flue gas duct at the tail of a boiler to recover the waste heat of the exhausted flue gas. Traditional economizers are classified by manufacturing materials: there are two types, cast iron and steel pipe economizers. The steel pipe economizer is composed of horizontally arranged parallel elbow pipes (commonly known as serpentine pipes). The economizer is generally arranged horizontally in the tail flue gas duct. Its working principle is: using water to flow upward in the serpentine pipe, and the flue gas to flow horizontally from top to bottom outside the pipe to wash the pipe wall, so as to realize the heat exchange between the flue gas and the feed water;

[0003] Traditionally, the economizer pipe structure is relatively simple, and it is mostly fixed by welding the fixed seat with the serpentine pipe, resulting in the inability to adjust the position of the fixed seat, and it cannot adapt to the installation environment with large concave and convex height differences, and the practicability is insufficient. Once there are pits or other insufficient horizontal conditions at the installation position, it will lead to the abnormal installation of the economizer pipe, reducing the work efficiency. Therefore, we propose an economizer heat exchange tube convenient for installation. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. Traditionally, the economizer pipe structure is relatively simple, and there is a way of using fixing parts to weld with the serpentine pipe, resulting in the inability to adjust the position of the fixing parts, and the practicability is insufficient. Once there are protrusions or other insufficient horizontal conditions at the installation position, it will lead to the abnormal installation of the economizer pipe, reducing the work efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A plurality of sliding grooves are opened corresponding to the circular grooves near the inner side of the front side of the fixed seat. A sliding rod is arranged inside the sliding groove. An internal groove is opened corresponding to the sliding groove inside the fixed seat. An arc-shaped clamping member is arranged inside the internal groove.

[0008] As a preferred scheme of the utility model, the serpentine pipe body is adapted to the circular groove.

[0009] The technical effect of adopting the above further solution is that: through the adaptation of the serpentine tube body and the circular groove, the serpentine tube body can be placed inside the circular groove to limit it and improve stability.

[0010] As a preferred solution of the present utility model, the fixing frame is fixedly connected to the fixing seat, and the fixing ring is welded to the fixing frame.

[0011] The technical effect of adopting the above further solution is that: through the welding of the fixing ring and the fixing frame, the fixing ring can be made more firm, improving the fixing strength of the serpentine tube body.

[0012] As a preferred solution of the present utility model, the fixing ring is adapted to the serpentine tube body, and the first threaded rod is adapted to the fixing frame and the fixing ring.

[0013] The technical effect of adopting the above further solution is that: by rotating the first threaded rod, it can cooperate with the fixing ring to squeeze and fix the serpentine tube body, achieving the purpose of positioning the fixing seat.

[0014] As a preferred solution of the present utility model, the sliding rod is slidably connected to the sliding groove, and the arc-shaped clamping member is adapted to the sliding rod.

[0015] The technical effect of adopting the above further solution is that: through the adaptation of the arc-shaped clamping member and the sliding rod, after the sliding rod slides to a suitable position, the arc-shaped clamping member can be squeezed so that it fits with the sliding rod, completing the positioning of the sliding rod.

[0016] As a preferred solution of the present utility model, a second threaded rod is provided on the outer side of the fixing seat extending into the inner part of the built-in groove, and the second threaded rod is rotatably connected to the arc-shaped clamping member.

[0017] The technical effect of adopting the above further solution is that: by rotating the second threaded rod, it can drive the arc-shaped clamping member to squeeze and fix the sliding rod.

[0018] Compared with the prior art, the beneficial effect of the present utility model is:
