Description

Technical Field

[0001] The utility model relates to the technical field of boiler condensers, in particular to a boiler condenser. Background Art

[0002] A steam boiler refers to an industrial boiler that heats water to certain parameters and produces high-temperature steam. The water is heated in the drum and becomes steam, and the fire emits heat in the furnace. This is the principle of a steam boiler. When using a steam boiler, a condenser is required, and the condenser is a type of heat exchanger.

[0003] For example, Chinese patent publication number CN220153295U discloses a condenser for a steam boiler, comprising a mounting frame, a straight pipe section disposed within the mounting frame, U-shaped elbows fixedly connected to both sides of the straight pipe section, and a connection block fixedly connected to the top of the mounting frame. The condenser of the steam boiler is provided with a limiting hoop, a fixing block, a mounting block, and a rubber pad.

[0004] The above-mentioned reference documents address the problem of the inconvenience of limiting and fixing the straight pipe section in the condenser, which easily affects its use;

[0005] However, when the above-mentioned boiler condenser is in use, the multiple groups of condensing tubes installed side by side at equal intervals inside the installation frame can only be limited by limiting hoops for the upper and lower sections of the condensing tubes. In this way, the middle parts of the multiple groups of condensing tubes arranged vertically side by side lack limiting supports and are prone to deformation. In addition, the limiting hoops on the multiple groups of condensing tubes arranged side by side need to be disassembled and assembled separately when releasing the clamping and positioning of the condensing tubes, which makes the operation of disassembling and assembling the condensing tubes extremely inconvenient. Utility Model Content

[0006] The purpose of the utility model is to provide a condenser for a boiler, which, when in use, can realize synchronous support and positioning of multiple groups of vertically arranged condensing tubes inside the installation frame, thereby increasing the stability of the limiting support on the middle part of the condensing tubes. At the same time, the limiting support of multiple groups of side-by-side condensing tubes can be released synchronously, which is quick and convenient.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a condenser for a boiler, comprising a mounting frame and a serpentine pipe, wherein a water inlet pipe and a water outlet pipe are respectively provided at the top and bottom of one side of the mounting frame, support plates are symmetrically fixedly installed on both sides of the interior of the mounting frame, mounting plates are fixedly installed on the side of the support plates, a slide plate is slidably installed inside the mounting plate, a rack is fixedly connected to the top of the slide plate, and a limiting hoop is fixedly installed at equal intervals on one side of the slide plate, a circular long shaft is rotatably installed on the inner wall of the mounting frame at equal intervals, a transmission gear is fixedly provided in the middle of the circular long shaft, a worm gear is fixedly provided in a fixed sleeve at one end of the circular long shaft close to the water inlet pipe, a rotating shaft is rotatably installed on the side of the mounting frame close to the water inlet pipe, a worm is fixedly provided on the outside of the rotating shaft at equal intervals, and the outer edges of the worm are respectively meshed with the corresponding outer edges of the worm gear.

[0008] Preferably, a protective plate is fixedly mounted on a side of the mounting frame close to the water inlet main pipe, and the rotating shaft is rotatably mounted in an inner wall of the protective plate.

[0009] Preferably, the top ends of the multiple groups of serpentine tubes are respectively connected to the water inlet main pipe, and the bottom ends of the multiple groups of serpentine tubes are respectively connected to the water outlet main pipe.

[0010] Preferably, the rack is a T-shaped structure, and the outer edge of the rack is meshed with the outer edge of the corresponding transmission gear.

[0011] Preferably, a plurality of groups of the limiting hoops are respectively clamped to the outside of the corresponding serpentine tubes.

[0012] Preferably, mounting seats are rotatably mounted at equal intervals on the outside of the circular long axis, and the mounting seats are fixedly mounted on the outer edges of the corresponding mounting plates.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model rotates the rotating shaft, and multiple groups of worms respectively drive corresponding worm wheels, so that the circular long shafts installed in parallel between the multiple groups of support plates rotate synchronously, so that the gears on the circular long shafts drive the corresponding racks, so that the slide plate on the rack can slide up and down along the mounting plate, so that the multiple groups of equally spaced limit hoops on the slide plate can move up and down, so that they can be dislocated with the serpentine tubes, and the positioning of multiple parallel sections of each group of serpentine tubes is released, which increases the stability of the limit support in the middle of the condenser tube. At the same time, the limit support of multiple groups of side-by-side condenser tubes is released synchronously, which is fast and convenient, and solves the problems of lack of limit support in the middle of multiple groups of vertically side-by-side condenser tubes, which are prone to deformation, and the limit hoops on multiple groups of side-by-side condenser tubes need to be disassembled and assembled separately when the condenser tubes are clamped and positioned, which makes the operation of disassembling and assembling the condenser tubes very inconvenient.
