Description

Technical Field

[0001] This utility model relates to the field of industrial energy, specifically a water-cooled premixed gas steam generator. Background Technology

[0002] A water-cooled premixed steam generator is an advanced thermal energy conversion device. It generates high-temperature, high-pressure steam by pre-mixing fuel and air and igniting the mixture in a specific combustion chamber. This steam is then used to drive turbines for power generation, heating, or other industrial processes, achieving energy conversion and utilization. The core of the premixed steam generator lies in its unique combustion technology. Premixing refers to precisely controlling the mixing ratio of fuel (such as natural gas) and air before combustion to achieve optimal combustion results. This mixture is ignited in the combustion chamber, and due to its uniform mixing, combustion is more complete, resulting in more efficient conversion into thermal energy. The generated heat energy is transferred to water, heating it into steam, which in turn drives the turbine to perform work.

[0003] In existing water-cooled premixed steam generators, when the water level is too high, the steam carries more moisture, resulting in excessively high steam water content, which directly affects steam quality and may cause a sharp drop in steam temperature, impacting industrial production efficiency. Conversely, if the water level is too low, the steam may carry water, further deteriorating steam quality. Therefore, observing the water level through a transparent window is essential. However, existing water-cooled premixed steam generators still have the following problems in water level observation: Existing water contains a large amount of scale, which affects operators' ability to observe water levels, causing great inconvenience. Furthermore, scale in water level gauges is difficult to remove, increasing the difficulty of subsequent cleaning. Therefore, it is necessary to develop a water-cooled premixed gas-fired steam generator for use in existing industrial energy fields. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the presence of large amounts of scale in water, which hinders operators from observing water levels and causes significant inconvenience, and the difficulty in removing scale from water level gauges, this invention proposes a water-cooled premixed gas-fired steam generator.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail as follows: This application discloses a water-cooled premixed gas-fired steam generator. (Refer to...) Figure 1 and Figure 3 as well as Figure 4A water-cooled premixed gas-fired steam generator includes a gas evaporator body 10. A connecting pipe 22 is fixedly mounted on the side of the gas evaporator body 10. A water level cylinder 23 is fixedly mounted at one end of the connecting pipe 22. The bottom of the water level cylinder 23 has an opening. An external thread is fixedly mounted on the lower part of the surface of the water level cylinder 23. A water level window 30 is fixedly mounted on the water level cylinder 23. A scale line 31 is fixedly mounted on the water level cylinder 23, located on one side of the water level window 30. A drain pipe 32 is fixedly mounted on the top of the water level cylinder 23. A drain valve 33 is mounted on the drain pipe 32. A sludge cleaning mechanism 40 is mounted on the water level cylinder 23. The sludge cleaning mechanism 40 includes a threaded sealing cap 4000, which is threadedly assembled with the external thread of the water level cylinder 23. Vertical rods 4003 are symmetrically fixedly mounted at the bottom of the threaded sealing cap 4000. Limiting blocks 4004 are fixedly mounted at the bottom of the two vertical rods 4003. A threaded rod 4005 is threaded onto the limiting block 4004. A handwheel 4006 is fixedly mounted at the bottom of the threaded rod 4005. A second flange 4012 is fixedly mounted at the top of the threaded rod 4005. A connecting rod 4008 is movably mounted on the threaded sealing cover 4000. The connecting rod 4008 is movably assembled with the opening of the water level cylinder 23. A first flange 4011 is fixedly mounted at the bottom of the connecting rod 4008. Multiple bolts 4013 are mounted on the first flange 4011 and the second flange 4012. Nuts 4014 are threaded onto the bolts 4013. A disc scraper 4009 is fixedly mounted at the top of the connecting rod 4008. A wiping sponge 4010 is fixedly mounted on the disc scraper 4009. An extension block 4007 is fixedly mounted on the end face of the limiting block 4004. A drain pipe 4001 is fixedly mounted at the bottom of the threaded sealing cover 4000. A drain valve 4002 is mounted on the drain pipe 4001.

[0019] In this invention, the handwheel 4006 is rotated, causing the threaded rod 4005 to rotate and move on the limiting block 4004. The connecting rod 4008 drives the disc scraper 4009 to move, so that the disc scraper 4009 can scrape off the scale on the inner wall of the water level cylinder 23. At the same time, the threaded rod 4005 drives the wiping sponge 4010 on the connecting rod 4008 to rotate, so that the wiping sponge 4010 can clean the inner wall of the water level cylinder 23, allowing the water level window 30 to clearly see the water level in the water level cylinder 23, thus improving the usage effect.

[0020] Reference Figure 4 and Figure 5The bottom of the extension block 4007 is equipped with a positioning and locking mechanism 41. The positioning and locking mechanism 41 includes an assembly block 4100, which is assembled with the bottom of the extension block 4007. The assembly block 4100 has an inner cavity 4101, a first locking hole 4102, and a second locking hole 4103 at its bottom. The first locking hole 4102 is located on one side of the second locking hole 4103, and both the first locking hole 4102 and the second locking hole 4103 communicate with the inner cavity 4101. A movable block 4104 is movably mounted on the inner cavity 4101. The movable block 4104 has a telescopic cavity 4105 inside, and a telescopic spring 4106 is fixedly mounted on the telescopic cavity 4105. A push plate 4107 is fixedly mounted on the bottom of 106. A telescopic button 4108 is fixedly mounted on the push plate 4107. The telescopic button 4108 moves through the movable block 4104 and engages with only one of the first locking holes 4102 and the second locking hole 4103. A traction block 4109 is fixedly mounted on the movable block 4104. The traction block 4109 moves through the assembly block 4100 and a connecting block 4110 is fixedly mounted on one end of the traction block 4109. A positioning block 4111 is fixedly mounted on one end of the connecting block 4110. The positioning block 4111 is located on one side of the assembly block 4100. A positioning slot 4112 is provided on the positioning block 4111 and engages with the handwheel 4006.

[0021] In this utility model, when the telescopic button 4108 is engaged with the first locking hole 4102, the positioning groove 4112 on the positioning block 4111 is engaged with the handwheel 4006, restricting the handwheel 4006 from driving the threaded rod 4005 to rotate and move on the limit block 4004. When the telescopic button 4108 is engaged with the second locking hole 4103, the positioning groove 4112 on the positioning block 4111 is moved away from the handwheel 4006, making it easier for the handwheel 4006 to drive the threaded rod 4005 to rotate and move on the limit block 4004.

[0022] Reference Figure 1 and Figure 2The gas evaporator body 10 is fixedly equipped with a burner interface 11, a viewing port 12, an inspection door 13, a controller 20, a pressure gauge assembly 21, a safety valve 42, a smoke outlet 43, a condensate outlet 50, a water inlet 51, a drain outlet 52, and a main steam valve 53.

[0023] In this utility model, during use, the main body 10 of the gas evaporator is connected to the burner interface 11 and the burner is installed. The burner can heat the water entering through the inlet 51. The flame can be observed through the observation port 12. The smoke generated by the burner can be discharged from the smoke outlet 43. The steam is discharged through the main steam valve 53. The steam condensate is discharged from the condensate outlet 50. The gas evaporator drain port 52 can be used for sewage discharge. Under the principle of communicating vessels, water flows into the interior of the water level cylinder 23 through the communicating pipe 22. The water level can be observed through the data next to the water level window 30.

[0024] Working principle: During use, the gas evaporator body 10 is connected to the burner interface 11, which heats the water entering through the inlet 51. The flame can be observed through the observation port 12. The smoke generated by the burner is discharged from the smoke outlet 43, the steam is discharged through the main steam valve 53, and the steam condensate is discharged from the condensate outlet 50. The gas evaporator drain port 52 can be used for drainage. Under the principle of communicating vessels, water flows into the water level cylinder 23 through the communicating pipe 22. The water level can be observed through the data next to the water level window 30. When the telescopic button 4108 engages with the first locking hole 4102, the positioning slot 4112 on the positioning block 4111 engages with the handwheel 4006, limiting the movement of the handwheel 4006. The threaded rod 4005 rotates on the limiting block 4004. When the telescopic button 4108 engages with the second locking hole 4103, the positioning slot 4112 on the positioning block 4111 moves away from the handwheel 4006, allowing the handwheel 4006 to drive the threaded rod 4005 to rotate on the limiting block 4004. The connecting rod 4008 drives the disc scraper 4009 to move, allowing the disc scraper 4009 to scrape away the scale on the inner wall of the water level cylinder 23. At the same time, the threaded rod 4005 drives the wiping sponge 4010 on the connecting rod 4008 to rotate, allowing the wiping sponge 4010 to clean the inner wall of the water level cylinder 23, so that the water level window 30 can clearly see the water level in the water level cylinder 23, improving the usage effect.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
