Description

Technical Field

[0001] The utility model relates to the field of serpentine tubes, in particular to a boiler economizer serpentine tube. Background Art

[0002] Coiled tubes are a type of boiler heat transfer component, typically consisting of numerous curved U-shaped tubes. These tubes are installed in the boiler, allowing flue gases to enter through external channels and transferring water or steam internally. Boiler coiled tubes are typically made of carbon steel or stainless steel and can withstand high temperatures and pressures.

[0003] The Chinese patent with publication number CN215172762U provides a boiler economizer serpentine tube, including a positioning plate, a serpentine tube and a mounting plate. Two positioning plates are provided, and multiple through holes are opened on the upper surfaces of the two positioning plates. The serpentine tube is arranged in the multiple through holes. A fixing plate is provided on the left side of the front surface of the two positioning plates and on the right side of the front surface of the two positioning plates. A connecting plate is provided in the middle of the front surface of the two fixing plates. A fastening plate is provided in the middle of the upper surface of the two connecting plates. Through holes are opened on the left side of the upper surface of the two fastening plates and on the right side of the upper surface of the two fastening plates.

[0004] Although the above patent makes it convenient for the staff to install the economizer serpentine tube, and it is also convenient for the staff to replace the economizer serpentine tube when it is damaged, after the serpentine tube economizer has been working for a period of time, due to the presence of a large amount of sediment inside the pipe, more and more dirt will accumulate in the pipe, and problems such as pipe blockage may occur. In order to prevent this situation from happening, the staff need to clean the inside of the serpentine tube frequently. The cleaning is mostly done by flushing with clean water and hooking out the blockage inside with a hook. This is very time-consuming and labor-intensive, and greatly increases the burden on the staff. Utility Model Content

[0019] In order to make the technical methods, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-5 The boiler economizer serpentine tube shown includes a serpentine tube body 1, two groups of threaded tubes 3 are respectively threadedly connected to the two ends of the serpentine tube body 1, two groups of filter plates 310 are respectively fixedly installed at one end of the two groups of threaded tubes 3, and one group is aligned with the water inlet and the other group is aligned with the water outlet. One end of the fixed tube 311 is fixedly connected to one side of the filter plate 310, the rotating tube 312 is rotatably connected to the fixed tube 311, and multiple groups of linkage teeth 313 are fixedly installed on the surface of the rotating tube 312. The transmission gear 211 and the rotating tube 312 are meshed and connected, which can effectively prevent the clogging of the serpentine tube body 1.

[0021] Preferably, one side of the transmission gear 211 is fixedly connected to one end of the transmission shaft 210, and the other end of the transmission shaft 210 is fixedly connected to the output shaft of the motor 2, and the motor 2 is fixedly mounted on the mounting plate 114, and one side of the mounting plate 114 is fixedly connected to one end of the serpentine plate 110, and a group of storage boxes 112 are fixedly installed on the bottom of the end of the serpentine plate 110 corresponding to the water outlet, and a group of slides are fixedly opened on the bottom of the storage box 112, and the storage box 112 is slidably connected to the moving plate 113 through the slides. Two groups of sliders are fixedly installed on the moving plate 113, and the sliders on the moving plate 113 and the slides opened on the bottom of the storage box 112 are adapted to each other. A group of tilting blocks 115 are fixedly connected to the end of the serpentine plate 110 corresponding to the water inlet of the serpentine pipe body 1,

[0022] (1) When the water flow in the present invention needs to pass through the serpentine tube body 1, it will first pass through the filter plate 310 fixedly installed on the threaded cylinder 3. At this time, the block objects in the water will be blocked outside the serpentine tube body 1, thereby preventing them from entering the inside of the serpentine tube body 1 and forming a blockage. When the equipment is completed, the motor 2 is started. At this time, the motor 2 will drive the transmission shaft 210 and the transmission gear 211 to rotate in the positive direction, and the linkage teeth 313 and the transmission gear 211 are meshed and connected, so the linkage teeth 313 and the rotating cylinder 312 will also rotate accordingly. When the notch opened on the rotating cylinder 312 and the notch opened on the fixed cylinder 311 coincide with each other, the motor 2 stops rotating. At this time, the blockage blocked outside the serpentine tube body 1 will fall onto the barrier strip 116;

[0023] It should be noted here that the motor 2 first rotates in the forward direction, and the reverse rotation resets the rotating cylinder 312, and the number of rotations corresponds to the circumference of the rotating cylinder 312 to prevent the rotation distance from being exceeded and affecting the normal operation of the equipment.

[0024] (2) In the present invention, a group of water pipes are externally connected to the barrier strip 116, which are not shown. When the staff turns on the switch, water will flow out along the water pipes, thereby flushing the blockage into the storage box 112 through the serpentine plate 110. After the flushing is completed, the motor 2 is started again. At this time, the rotation direction of the motor 2 is reversed, thereby driving the rotating cylinder 312 to return to the initial position. After the rotating cylinder 312 is reset, the staff only needs to slide the movable plate 113 to remove the blockage from the storage box 112 and clean it. This not only prevents the serpentine tube body 1 from being blocked, but also quickly cleans the blockage, effectively improving work efficiency.

[0025] Working principle: After the device is started, when water needs to pass through the serpentine tube body 1, it will first pass through the filter plate 310 fixedly installed on the threaded cylinder 3. At this time, the block objects in the water will be blocked outside the serpentine tube body 1, thereby preventing them from entering the inside of the serpentine tube body 1 and forming a block. When the device is running, start the motor 2. At this time, the motor 2 will drive the transmission shaft 210 and the transmission gear 211 to rotate forward, and the linkage teeth 313 and the transmission gear 211 are meshed and connected, so the linkage teeth 313 and the rotating cylinder 312 will also rotate accordingly. When the notch opened on the rotating cylinder 312 and the notch opened on the fixed cylinder 311 coincide with each other, the motor 2 stops rotating. At this time, the blocked The obstruction outside the serpentine tube body 1 will fall onto the barrier strip 116. A set of water pipes are connected to the barrier strip 116, which is not shown. When the staff turns on the switch, water will flow out along the water pipe, thereby flushing the obstruction into the storage box 112 through the serpentine plate 110. After the flushing is completed, the motor 2 is started again. At this time, the rotation direction of the motor 2 is reversed, thereby driving the rotating cylinder 312 to return to the initial position. After the rotating cylinder 312 is reset, the staff only needs to slide the movable plate 113 to remove the obstruction from the storage box 112 and clean it. This not only prevents the serpentine tube body 1 from being blocked, but also quickly cleans the obstruction, effectively improving work efficiency.

[0026] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements fall within the scope of protection claimed by the present invention.
