Description

Technical Field

[0001] This utility model relates to the field of hot water boiler technology, specifically to a novel fully premixed low-NOx condensing gas-fired hot water boiler. Background Technology

[0002] Fully premixed condensing gas boilers are widely used due to their advantages such as low flue gas pollution, low corrosion resistance of convection tube bundles, good heat transfer effect, strong thermal radiation capacity, low exhaust gas temperature, and significantly improved thermal efficiency. In addition, fully premixed condensing gas boilers do not require auxiliary equipment such as gas supply, slag remover, dust remover, and grate, saving boiler equipment investment. To facilitate the movement of equipment, a moving device is usually installed at the bottom of the hot gas boiler.

[0003] Existing fully premixed low-NOx condensing gas-fired hot water boilers have limitations because the protective frame is not enclosed, making the equipment easily susceptible to impacts from external objects, which affects the service life of the equipment. Furthermore, when the hot water boiler malfunctions and needs maintenance, its compact structure can obstruct direct maintenance, requiring disassembly and thus reducing maintenance efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel fully premixed low-NOx condensing gas-fired hot water boiler to overcome the aforementioned technical problems in existing related technologies.

[0005] A novel fully premixed low-NOx condensing gas-fired hot water boiler includes a support frame, a fully premixed air intake device, a flue gas condensing device, and a hot water boiler body. The fully premixed air intake device and the flue gas condensing device are both fixedly installed at one end of the support frame. The support frame is fixedly installed on its top, with a top plate fixedly installed on the top of the support frame by several bolts, and fixed plates fixedly installed at both ends. Several storage frames are fixedly installed on the inner wall of the support frame, and two sliding grooves are formed therein. Protective plates are slidably fitted onto the inner walls of the storage frames. Fixed rods are fixedly installed at both ends of the protective plates. An adjustment assembly is provided between the protective plates and the support frame. The adjustment assembly includes a first bidirectional lead screw, a second bidirectional lead screw, and a belt. The belt can drive the first bidirectional lead screw and the second bidirectional lead screw to rotate simultaneously, and drive the several protective plates to move horizontally.

[0006] Preferably, the fixing rod slides into the groove, both ends of the protective plate are in contact with the inner wall of the storage frame, a limiting frame is fixedly installed on the top of the support frame, and the hot water boiler body is set inside the limiting frame.

[0007] Preferably, two of the protective plates are threaded onto the first bidirectional lead screw, and the other two protective plates are threaded onto the second bidirectional lead screw. A rotating shaft is fixedly installed at one end of the first bidirectional lead screw, and a motor is fixedly connected to one end of the rotating shaft.

[0008] Preferably, a protective shell is fixedly installed on the outer wall of the support frame, and the motor is fixedly installed inside the protective shell.

[0009] Preferably, the adjusting assembly further includes two pulleys, the first bidirectional lead screw, the second bidirectional lead screw, and the rotating shaft are all rotatably connected to the support frame, the two pulleys are respectively fixedly sleeved on the second bidirectional lead screw and the first bidirectional lead screw, and the belt is sleeved on the two pulleys.

[0010] Preferably, a plurality of legs are fixedly installed at the bottom of the support frame, and the bottom of the legs is provided with casters.

[0011] Preferably, a mounting frame is fixedly installed at one end of the protective plate, and a heat dissipation plate is fixedly installed on the inner wall of the mounting frame.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a novel fully premixed low-NOx condensing gas-fired hot water boiler. The boiler body can be protected by a protective plate, a fixing plate, a support frame, and a top plate. This protects the boiler body during use and movement, not only preventing dust but also avoiding impacts from external objects, thereby reducing the probability of damage and extending the service life of the equipment.

[0014] 2. This utility model provides a novel fully premixed low-NOx condensing gas-fired hot water boiler. Through the mutual cooperation between the motor, shaft, double-ended lead screw one, double-ended lead screw two, pulley, belt, protective plate, fixing plate, top plate, bolts, and support frame, when the output end of the motor rotates, it drives double-ended lead screw one and double-ended lead screw two to rotate through the shaft, pulley, and belt. When double-ended lead screw one and double-ended lead screw two rotate, they are threadedly engaged with the two protective plates and drive the two protective plates to move in opposite directions. This allows the two protective plates to be opened quickly, facilitating the maintenance of the hot water boiler body without requiring the entire hot water boiler body to be disassembled. This effectively reduces the difficulty of operation and improves maintenance efficiency and applicability. Attached Figure Description

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1-5 As shown, this utility model provides a novel fully premixed low-NOx condensing gas-fired hot water boiler, including a support frame 1, a fully premixed air intake device 101, a flue gas condensing device 102, and a hot water boiler body 10. The fully premixed air intake device 101 and the flue gas condensing device 102 are both fixedly installed at one end of the support frame 1. The support frame 1 is fixedly installed on the top of the support frame 1. A top plate 7 is fixedly installed on the top of the support frame 1 by several bolts 8, and fixed plates 9 are fixedly installed at both ends. Several storage frames 2 are fixedly installed on the inner wall of the support frame 1, and two sliding grooves 100 are opened. Protective plates 3 are slidably fitted on the inner wall of the storage frames 2. Fixed rods 304 are fixedly installed at both ends of the protective plates 3. An adjustment component 4 is provided between the protective plates 3 and the support frame 1. The adjustment component 4 includes a bidirectional lead screw 1 403, a bidirectional lead screw 2 404, and a belt 406. The belt 406 can drive the bidirectional lead screw 1 403 and the bidirectional lead screw 2 404 to rotate simultaneously and drive the several protective plates 3 to move horizontally.

[0024] After the hot water boiler body 10, the fully premixed air intake device 101 and the flue gas condensing device 102 are installed, the hot water boiler body 10 is installed on the top of the support frame 1. Then, the rotation direction and number of turns of the adjusting motor 401 are adjusted so that the two adjacent protective plates 3 abut against each other, sealing the two sides of the support frame 1. Then, the fixing plate 9 and the top plate 7 are fixedly installed on the two sides and the top of the support frame 1 respectively, thereby sealing and protecting the hot water boiler body 10. This not only prevents dust but also avoids being hit by external objects, thereby reducing the probability of damage and extending the life of the equipment.

[0025] The hot water boiler body 10, the flue gas condensing device 102, and the fully premixed air intake device 101 are all existing technologies, and their connection methods are common knowledge and will not be explained here.

[0026] like Figure 3-5 As shown, in one embodiment, the fixing rod 304 slides into the slide groove 100, both ends of the protective plate 3 are attached to the inner wall of the storage frame 2, the top of the support frame 1 is fixedly installed with a limiting frame 103, the hot water boiler body 10 is set in the limiting frame 103, two protective plates 3 are threaded onto the first bidirectional screw 403, and the other two protective plates 3 are threaded onto the second bidirectional screw 404. A rotating shaft 402 is fixedly installed at one end of the first bidirectional screw 403, and a motor 401 is fixedly connected to one end of the rotating shaft 402. A protective shell is fixedly installed on the outer wall of the frame 1. The motor 401 is fixedly installed inside the protective shell. The adjustment assembly 4 also includes two pulleys 405. The first bidirectional lead screw 403, the second bidirectional lead screw 404 and the rotating shaft 402 are all rotatably connected to the support frame 1. The two pulleys 405 are respectively fixedly sleeved on the second bidirectional lead screw 404 and the first bidirectional lead screw 403. The belt 406 is sleeved on the two pulleys 405. A mounting frame 301 is fixedly installed at one end of the protective plate 3. A heat dissipation plate 302 is fixedly installed on the inner wall of the mounting frame 301.

[0027] When the staff needs to inspect the hot water boiler body 10, they start the motor 401. When the output end of the motor 401 rotates, it drives the rotating shaft 402 to rotate. After the rotating shaft 402 rotates, it drives the double-acting screw 403 to rotate. When the double-acting screw 403 rotates, two of the protective plates 3 are threaded together and move in opposite directions. When the double-acting screw 403 rotates, it can also drive one of the pulleys 405 to rotate. At this time, the two pulleys 405 cooperate with the belt 406 and drive the double-acting screw 404 to rotate. When the double-acting screw 404 rotates, it is threaded together with the other two protective plates 3 and moves in opposite directions. This allows several protective plates 3 to be moved quickly, increasing the distance between them. After the two protective plates 3 are fully opened, the staff can directly inspect the hot water boiler body 10 without having to disassemble the entire hot water boiler body 10. This effectively reduces the difficulty of operation and improves the efficiency and applicability of maintenance.

[0028] The heat dissipation plate 302 can dissipate heat from the hot water boiler body 10, reducing the probability of the hot water boiler body 10 being damaged due to excessive temperature.

[0029] like Figure 2 As shown, in one embodiment, a plurality of support legs 5 are fixedly installed at the bottom of the support frame 1, and casters 6 are provided at the bottom of the support legs 5.

[0030] The working principle of this new type of fully premixed low-NOx condensing gas-fired hot water boiler will be explained in detail below:

[0031] When the staff needs to inspect the hot water boiler body 10, they start the motor 401. When the output end of the motor 401 rotates, it drives the rotating shaft 402 to rotate. After the rotating shaft 402 rotates, it drives the double-acting screw 403 to rotate. When the double-acting screw 403 rotates, two of the protective plates 3 are threaded together and move in opposite directions. When the double-acting screw 403 rotates, it can also drive one of the pulleys 405 to rotate. At this time, the two pulleys 405 cooperate with the belt 406 and drive the double-acting screw 404 to rotate. When the double-acting screw 404 rotates, it is threaded together with the other two protective plates 3 and moves in opposite directions. This allows several protective plates 3 to be moved quickly, increasing the distance between them. After the two protective plates 3 are fully opened, the staff can directly inspect the hot water boiler body 10 without having to disassemble the entire hot water boiler body 10. This effectively reduces the difficulty of operation and improves the efficiency and applicability of maintenance.

[0032] When the equipment is in normal use or moved, the protective plates 3, fixing plates 9, bearing frames 1 and top plates 7 can protect the main body 10 of the hot water boiler. They can not only prevent dust but also prevent it from being hit by external objects, thereby reducing the probability of damage and extending the service life of the equipment.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
