Description

Technical Field

[0001] This utility model relates to the field of burner technology, specifically to an air intake control device for burner thermal control. Background Technology

[0002] As a key device that mixes fuel and air for combustion to output heat energy, the burner is widely used in many fields such as industrial heating, boiler heating, chemical reaction, and power generation. Its combustion efficiency, operational stability, safety, and environmental performance directly affect the energy consumption cost, service life, and environmental impact of the equipment. Air (oxygen) is an indispensable element for combustion reaction, and whether its supply quantity and supply method are reasonable is one of the core factors that determine the combustion effect.

[0003] Existing devices such as Figure 8 As shown, its core adjustment component is a circular baffle. The outer diameter of the baffle is precisely matched with the inner diameter of the air duct. During assembly, the air duct and the burner air inlet are sealed together. By driving the rotating shaft to rotate, the circular baffle can be rotated synchronously to a preset angle. This angle adjustment mechanism can accurately control the airflow entering the air duct, thereby achieving effective control of the burner's combustion state.

[0004] However, the working environment of burners is often dusty. During the air intake process, impurities in the air enter the air duct with the airflow and are easily attached to the surface of the baffle. These attached impurities will interfere with the normal adjustment function of the baffle, which will lead to fluctuations and instability in the air intake airflow, which may have an adverse effect on the combustion efficiency and stability of the burner. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an air intake control device for burner thermal control, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A burner thermal control air intake regulating device includes: an air duct pipe with a perforation on one side;

[0008] The opening and closing assembly includes a baffle, a rotating shaft, and a fixing component; the rotating shaft is rotatably installed inside the air duct, one end of the rotating shaft is through a hole, the extended end of the rotating shaft is provided with a handle, and the fixing component is installed on the handle; the outer wall of the rotating shaft is provided with a baffle, and the baffle is rotatably placed inside the air duct.

[0009] The cleaning assembly includes a main shaft, a rotating sleeve, mounting strips, and a scraper. The main shaft is fixedly installed in the middle of the surface of the baffle. The rotating sleeve is fitted on the outer wall of the main shaft. Mounting strips are arranged in a ring array on the side wall of the rotating sleeve. A scraper is provided on the inner side of each set of mounting strips, and the scraper contacts the baffle.

[0010] Furthermore, the side wall of the air duct is provided with a fixing block, which is located outside the perforation. The fixing block has a through hole inside, through which the rotating shaft passes. The side wall of the fixing block has multiple sets of threaded holes.

[0011] Furthermore, a rubber ring is provided on the inner wall of the through hole, and the rubber ring fits into the rotating shaft.

[0012] Furthermore, the fixing component includes a threaded post and a handle. The threaded post has a through thread, the outer end of the threaded post has a handle, and the inner end of the threaded post is screwed into a threaded hole.

[0013] Furthermore, the bottom surface of the baffle is provided with an arc-shaped groove, and multiple sets of spring columns are installed inside the arc-shaped groove. The outer end of the spring column is provided with a sealing strip, and the outer wall of the sealing strip is provided with an inclined groove.

[0014] Furthermore, the inner wall of the air duct is provided with a sealing groove, and the sealing strip is fitted into the sealing groove.

[0015] Furthermore, a silicone strip is provided at the end of the scraper.

[0016] Compared with the prior art, the beneficial effects of this utility model include:

[0017] 1. During the air intake process, dust in the air may adhere to the baffle, affecting its operation. When the burner is intake air and the baffle is perpendicular to the air duct, the rapid airflow can drive the mounting strip to rotate around the main shaft, thereby driving the scraper to move in a circular motion. This allows the scraper to clean the dust adhering to the outside of the baffle, keeping the outside of the baffle clean and tidy, thus preventing the baffle from affecting the air intake of the burner.

[0018] 2. When the air intake of the burner needs to be adjusted, the operator can rotate the handle to rotate the baffle at a certain angle. At this time, the threaded post and the threaded hole are aligned. When the baffle needs to be kept at a certain rotation angle, the operator can turn the handle to drive the threaded post into the threaded hole, thereby fixing the position of the baffle. When air intake is not needed, the operator can turn the handle to drive the sealing strip into the sealing groove. The elasticity of the spring post can drive the sealing strip to be firmly locked into the sealing groove, thereby achieving all-round shielding of the air duct by the baffle, thereby quickly stopping the air intake of the burner and protecting the equipment.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] like Figure 1 - Figure 8As shown, this utility model provides an air intake control device for burner thermal control, comprising:

[0031] The air duct 1 has a perforation 11 on one side;

[0032] The opening and closing assembly includes a baffle 3, a rotating shaft 13, and a fixing component; the rotating shaft 13 is rotatably installed inside the air duct 1, one end of the rotating shaft 13 passes through the through hole 11, and the extended end of the rotating shaft 13 is provided with a handle 2, on which the fixing component is installed; the outer wall of the rotating shaft 13 is provided with a baffle 3, and the baffle 3 is rotatably placed inside the air duct 1;

[0033] The cleaning assembly includes a main shaft 4, a rotating sleeve 10, mounting strips 5, and a scraper 19. The main shaft 4 is fixedly installed in the middle of the surface of the baffle 3. The rotating sleeve 10 is fitted on the outer wall of the main shaft 4. The mounting strips 5 are arranged in a ring array on the side wall of the rotating sleeve 10. Each set of mounting strips 5 has a scraper 19 on its inner side, and the scraper 19 is in contact with the baffle 3.

[0034] In the above scheme:

[0035] 1. By turning the handle 2, the rotating shaft 13 can be driven to rotate, which in turn drives the baffle 3 to rotate, so that the staff can accurately control the air intake. By spiraling the threaded column 15 into the threaded hole 8, the rotation angle of the baffle 3 can be controlled.

[0036] 2. The elastic force of the spring column 9 can drive the sealing strip 16 into the sealing groove 6, thereby sealing the air duct 1 and quickly stopping the air intake to the burner.

[0037] 3. The rapidly flowing air can blow the mounting strip 5, which can drive the mounting strip 5 to rotate around the main shaft 4, so that the scraper 19 and the silicone strip 12 can cooperate to clean the surface of the baffle 3.

[0038] In this embodiment, the side wall of the air duct 1 is provided with a fixing block 21, which is located outside the through hole 11. The fixing block 21 has a through hole 20 inside, through which the rotating shaft 13 passes. The side wall of the fixing block 21 has multiple sets of threaded holes 8.

[0039] In the above scheme: multiple sets of threaded holes 8 are evenly distributed on the fixing block 21 with the rotating shaft 13 as the center. The diameter of the threaded holes 8 matches the outer diameter of the threaded post 15, which makes it easy to fix the baffle 3 at different angles.

[0040] In this embodiment, a rubber ring 7 is provided on the inner wall of the through hole 20, and the rubber ring 7 is in contact with the rotating shaft 13.

[0041] In the above scheme: when the rotating shaft 13 rotates, the rubber ring 7 generates a moderate friction force with the rotating shaft 13, which not only prevents the leakage of flue gas inside the air duct 1, but also buffers the rotation speed of the rotating shaft 13, making it easier for the staff to accurately control the rotation angle of the baffle 3.

[0042] In this embodiment, the fixing component includes a threaded post 15 and a handle 14. The threaded post 15 is threaded through, and the handle 14 is provided at the outer end of the threaded post 15. The inner end of the threaded post 15 is screwed into a threaded hole 8.

[0043] In the above scheme: when the baffle 3 is rotated to the target angle, the threaded post 15 is vertically aligned with one of the threaded holes 8. Turning the handle 14 can screw the threaded post 15 into the threaded hole 8, thereby locking the position of the baffle 3.

[0044] In this embodiment, the bottom surface of the baffle 3 is provided with an arc-shaped groove 17, and multiple sets of spring posts 9 are installed inside the arc-shaped groove 17. The outer end of the spring post 9 is provided with a sealing strip 16, and the outer wall of the sealing strip 16 is provided with an inclined groove 18.

[0045] In the above scheme: multiple sets of spring columns 9 are evenly distributed along the length direction on the inner side of each set of arc grooves 17. When the baffle 3 rotates, the spring columns 9 can adapt to the curvature change of the inner wall of the air duct 1 by extension and retraction, ensuring that the sealing strip 16 always maintains a close fit with the inner wall of the air duct 1. The inclined groove 18 can guide the sealing strip 16 to slide smoothly into the groove to achieve a tight fit.

[0046] In this embodiment, a sealing groove 6 is provided on the inner wall of the air duct 1, and the sealing strip 16 is fitted into the sealing groove 6.

[0047] In the above scheme: when the baffle 3 is rotated to the closed position, the sealing strip 16 is embedded in the sealing groove 6 under the thrust of the spring column 9.

[0048] In this embodiment, a silicone strip 12 is provided at the end of the scraper 19.

[0049] In the above scheme: a silicone strip 12 is fixed to the end of the scraper 19. The outer edge of the silicone strip 12 is in close contact with the surface of the baffle 3, and can scrape off the dust and impurities on the surface of the baffle 3 as the mounting strip 5 rotates.

[0050] In this embodiment, when the burner's air intake needs adjustment, the operator rotates handle 2, which in turn drives the baffle 3 to rotate via the main shaft 4. When the baffle 3 rotates to a certain angle, the threaded hole 8 and the threaded post 15 are aligned. The operator then turns handle 14, causing the threaded post 15 to spirally engage with the threaded hole 8, thus fixing the position of the baffle 3. This facilitates precise control of the burner's air intake. When the burner's air intake needs to be stopped immediately, the operator controls the threaded post 15 to disengage from the threaded hole 8, and then controls handle 2 to rotate, causing the baffle 3 to rotate and engage the sealing strip 16 into the sealing groove 6, thereby stopping the baffle. The baffle 3 and the air duct 1 can be tightly connected together, thereby achieving a seal between the baffle 3 and the air duct 1, which enables the burner to quickly stop air intake and protect the equipment. The rubber ring 7 increases the friction between the rotating shaft 13 and the air duct 1 when the shaft 13 rotates, making it easier for the operator to control the rotation of the shaft 13. When the burner is intaked, the rapidly flowing air can drive the mounting strip 5 to rotate around the main shaft 4, which allows the scraper 19 to clean the surface of the baffle 3. The silicone strip 12 enables a thorough cleaning of the surface of the baffle 3, allowing simultaneous cleaning of both the upper and lower sides of the baffle 3.
