Description
Technical Field
[0001] The utility model belongs to the technical field of steam generators, and in particular relates to a condensing heat exchange type steam generator. Background Art
[0002] A steam generator, also called a steam heat source machine, is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam.
[0003] The prior art discloses a condensing heat exchange steam generator (CN116357950A), which relates to the technical field of steam generators, and includes a mounting base and a burner, wherein the mounting base and the burner are connected by bolts, a chimney is provided on one outer wall of one side of the burner, an exhaust pipe is provided on one side of the top of the burner, and the top of the exhaust pipe is connected to a connecting pipe via a flange, an end of the outer wall of the connecting pipe away from the exhaust pipe is connected to a conduit via a flange, and one side of the conduit is connected to an air inlet pipe via a flange, a heat exchanger is provided at the bottom of the steam inlet pipe, a steam outlet is provided on one side of the heat exchanger near the top, and a guide plate is provided on the inner wall of the conduit.
[0004] After searching, it was found that the device uses steam to provide kinetic energy for the rotating blades, so that the rotating blades rotate, and the connecting shaft pushes the baffle to shake. However, the use of this method has certain requirements on the pressure of the conduit itself. If the steam content and pressure in the conduit are insufficient, it is not enough to generate kinetic energy to push the baffle in the opposite direction, so that the baffle cannot shake, causing water vapor to remain inside the conduit and continue to accumulate, eventually causing the air pressure inside the heat exchanger to increase, thereby causing damage to the heat exchanger; in addition, since the baffle is positioned by a telescopic rod when it is shaking, this causes the telescopic rod to continuously extend and retract when the baffle is constantly shaking. At the same time, since there is no buffer design in the telescopic rod, the telescopic rod will be worn over time, thereby affecting the overlap of the baffle and the guide port, thereby indirectly affecting the heat exchange efficiency.
[0005] In view of this, the present utility model is proposed. Utility Model Content
[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:
[0007] A condensing heat exchange steam generator comprises a conduit, a baffle being clamped inside the conduit, a telescopic structure for positioning the baffle being arranged inside the conduit, the telescopic structure comprising a positioning column, a rack connecting plate, a gear, a fixed block and a rack, the positioning column being fixedly connected to the baffle and the rack connecting plate, the fixed block being fixedly connected to the conduit and being rotationally connected to the gear, the rack connecting plate and the rack being both slidably connected to the fixed block and being transmission-connected to the same gear, and the rack connecting plate being elastically connected to the rack.
[0008] As a preferred embodiment of the utility model, the fixed block is fixedly connected to the inner wall surface of the catheter, the interior of the fixed block is a square through cavity, a rotating shaft is fixedly connected to the interior of the square through cavity, and the fixed block is rotatably connected to the gear through the rotating shaft.
[0009] As a preferred embodiment of the utility model, the top end of the positioning column is fixedly connected to the bottom of the baffle, the bottom end of the positioning column is fixedly connected to the top plate, two top plates are provided, the bottom of one of the top plates is fixedly connected to a stabilizing block, the top of the rack connecting plate is fixedly connected to the bottom of one of the top plates, and the stabilizing block and the rack connecting plate are symmetrically arranged.
[0010] As a preferred embodiment of the utility model, the stabilizing block and the rack connecting plate and the side are respectively fixedly connected with different first sliding blocks, and second sliding grooves are symmetrically opened in the square through cavity of the fixing block, and the first sliding blocks slide in the second sliding grooves.
[0011] As a preferred embodiment of the utility model, the other top plate is located at the bottom of the fixed block, the top surface of the other top plate is fixedly connected to the rack, two stabilizing blocks are provided, the other stabilizing block is fixedly connected to the top surface of the other top plate, and the other stabilizing block is symmetrically arranged with the rack.
[0012] As a preferred embodiment of the utility model, different second sliding blocks are fixedly connected to the sides of the other stabilizing block and the rack respectively, and a first sliding groove is symmetrically opened in the square through cavity of the fixed block. The first sliding groove is located next to the second sliding groove, and the second sliding block slides in the first sliding groove.
[0013] As a preferred embodiment of the utility model, a sleeve column is fixedly connected to the bottom of the rack connecting plate, and two sleeve columns are provided. The other sleeve column is located on the top surface of the other top plate, and is located between the other stabilizing block and the rack.

The rack connecting plate and the rack are respectively located on both sides of the gear, and the rack connecting plate and the rack are both meshed with the same gear.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. When the pressure is insufficient to push the baffle to move in the opposite direction, the buffer spring can use the released elastic force to bounce the rack plate and the rack apart, thereby causing the rack plate and the rack to move simultaneously, thereby providing thrust for the baffle, thereby helping the baffle to move in the opposite direction, so that the baffle can shake, thereby preventing water vapor from staying inside the conduit and accumulating continuously, thereby reducing the air pressure inside the heat exchanger, thereby protecting the heat exchanger and preventing damage to the heat exchanger.
[0016] 2. The transmission movement of the rack plate and the rack on the same gear can replace the telescopic rod to locate the trajectory of the baffle movement. At the same time, the meshing connection between the three can buffer the force of the continuous reciprocating motion of the baffle. By using the buffer spring, the automatic rebound of the entire telescopic structure can be guaranteed, thereby helping the baffle to overlap with the guide port, reducing the wear of the device and indirectly improving the heat exchange efficiency.

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0025] A condensing heat exchange steam generator, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a catheter 10, in which a baffle 11 is clamped, and a telescopic structure for positioning the baffle 11 is arranged inside the catheter 10, and the telescopic structure includes a positioning column 12, a rack connecting plate 15, a gear 17, a fixing block 18 and a rack 20. The positioning column 12 is fixedly connected to the baffle 11 and the rack connecting plate 15, the fixing block 18 is fixedly connected to the catheter 10 and is rotationally connected to the gear 17, the rack connecting plate 15 and the rack 20 are both slidably connected to the fixing block 18 and are transmission-connected to the same gear 17, and the rack connecting plate 15 is elastically connected to the rack 20.
[0026] The working principle is as follows. The size of the baffle 11 is adapted to the guide port set in the conduit 10. Since the top surface of the baffle 11 is connected to the connecting shaft, when the rotating blade drives the connecting shaft to move, the baffle 11 will be driven close to the guide port. At this time, the positioning column 12 connected to the bottom of the baffle 11 will pull the rack connecting plate 15 to slide in the fixed block 18, thereby realizing upward movement. At this time, the gear 17 will start to rotate under the drive of the rack connecting plate 15, and at the same time engage the rack 20 on the other side, so that the rack 20 moves downward in the fixed block 18; it is worth noting that the above-mentioned guide port, connecting shaft and rotating blade have been published in a prior art condensing heat exchange steam generator (CN116357950A), which will not be repeated here.
[0027] like Figure 1 and Figure 3 As shown, the fixed block 18 is fixedly connected to the inner wall surface of the conduit 10, the interior of the fixed block 18 is a square through cavity, and a rotating shaft is fixedly connected to the interior of the square through cavity, and the fixed block 18 is rotatably connected to the gear 17 through the rotating shaft; Figure 2 and Figure 3 As shown, the top end of the positioning column 12 is fixedly connected to the bottom of the baffle 11, and the bottom end of the positioning column 12 is fixedly connected to the top plate 13. There are two top plates 13, and the bottom of one of the top plates 13 is fixedly connected to a stabilizing block 14. The top of the rack connecting plate 15 is fixedly connected to the bottom of one of the top plates 13, and the stabilizing block 14 and the rack connecting plate 15 are symmetrically arranged; Figure 3 As shown, the stabilizing block 14 and the rack connecting plate 15 are respectively fixedly connected to different first sliding blocks 16 on the side, and the square through cavity of the fixing block 18 is symmetrically provided with second sliding grooves 24, and the first sliding blocks 16 slide in the second sliding grooves 24; Figure 3 As shown, another top plate 13 is located at the bottom of the fixed block 18, the top surface of the other top plate 13 is fixedly connected to the rack 20, two stabilizing blocks 14 are provided, another stabilizing block 14 is fixedly connected to the top surface of the other top plate 13, and the other stabilizing block 14 is symmetrically arranged with the rack 20; Figure 3 As shown, different second sliders 19 are fixedly connected to the sides of another stabilizing block 14 and the rack 20 respectively, and first slide grooves 23 are symmetrically opened in the square through cavity of the fixed block 18. The first slide grooves 23 are located next to the second slide grooves 24, and the second slider 19 slides in the first slide grooves 23.
[0028] The working principle is as follows: a bearing is provided on the curved surface of the rotating shaft, and the fixed block 18 is rotatably connected to the gear 17 through the bearing of the rotating shaft. The two top plates 13 are relatively arranged at both ends of the square through cavity of the fixed block 18, and the size of the top plate 13 is adapted to the size of the square through cavity. The first slide groove 23 and the second slide groove 24 are symmetrically arranged in the square through cavity. The first slide groove 23 and the second slide groove 24 have the same shape and size, and the first slider 16 and the second slider 19 have the same shape and size. Specifically, the bottom end of the positioning column 12 is connected to the top surface of the top plate 13 connected to the rack connecting plate 15. When the positioning column 12 is driven upward, the top plate 13 connected to the positioning column will drive the rack connecting plate 15 and the stabilizing block 14 upward. At this time, the stabilizing block 14 and the rack connecting plate 15 will be slidably connected to the fixed block 18 through the first slider 16, while the other stabilizing block 14 and the rack 20 at the other end are slidably connected to the fixed block 18 with the help of the second slider 19.
[0029] like Figure 3 and Figure 4 As shown, a sleeve column 21 is fixedly connected to the bottom of the rack connecting plate 15, and two sleeve columns 21 are provided. The other sleeve column 21 is located on the top surface of the other top plate 13, and is located between the other stabilizing block 14 and the rack 20. A buffer spring 22 is fixedly connected between the two sleeve columns 21. The rack connecting plate 15 is elastically connected to the other top plate 13 through the buffer spring 22. The rack connecting plate 15 and the rack 20 are respectively located on both sides of the gear 17, and the rack connecting plate 15 and the rack 20 are both meshed with the same gear 17.
[0030] The specific implementation is as follows. When water vapor contacts the rotating mechanism, the rotating blade will drive the rotating rod to rotate under the impact of water vapor. At this time, the connecting shaft drives the baffle 11 to swing back and forth. When the baffle 11 moves to one side, it will simultaneously push the positioning column 12 to move. At the same time, the top 13 connected to the positioning column 12 will also push the rack plate 15 and the stabilizing block 14 to slide in the fixed block 18. At the same time, the gear 17 will start to rotate due to the movement of the rack plate 15, causing the meshing rack 20 on the other side to move. At this time, the rack 2 0 is opposite to the movement direction of the rack connecting plate 15. During this process, when the rack 20 and the rack connecting plate 15 move inward at the same time because of the gear 17, the buffer spring 22 at the bottom of the rack connecting plate 15 will be squeezed. When the rack 20 and the rack connecting plate 15 move outward at the same time because of the gear 17, the buffer spring 22 will be released. The purpose of this is to prevent the situation of insufficient steam and insufficient pressure in the conduit. When the pressure is insufficient and the baffle 11 cannot be pushed to move in the reverse direction, the buffer spring 22 can use the released elastic force to push the rack connecting plate The rack plate 15 and the rack 20 are ejected, thereby causing the rack connecting plate 15 and the rack 20 to move simultaneously, thereby providing thrust for the baffle 11, thereby helping the baffle 11 to move in the opposite direction, so that the baffle 11 can be shaken, thereby preventing the water vapor from being accumulated inside the conduit, thereby reducing the air pressure inside the heat exchanger, thereby protecting the heat exchanger and preventing the heat exchanger from being damaged; in addition, the transmission movement of the rack connecting plate 15 and the rack 20 on the same gear 17 can replace the telescopic rod to locate the trajectory of the movement of the baffle 11, and at the same time use the three The meshing connection between them can buffer the force of the continuous reciprocating motion of the baffle 11, and by using the buffer spring 22, it can also ensure the automatic resilience of the entire telescopic structure, thereby helping the baffle 11 to overlap with the guide port, reducing the wear of the device and indirectly improving the heat exchange efficiency; it is worth noting that the above-mentioned rotating mechanism includes a rotating rod and a rotating blade, and the guide port, the connecting shaft and the rotating mechanism have been published in a condensing heat exchange steam generator (CN116357950A) in the prior art, which will not be repeated here.
