Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of combustion chamber technology, and more specifically, to a combustion chamber with externally adjustable airflow. Background Technology

[0002] Among various combustion devices, the combustion chamber is the core component, and its precise control of air intake has a decisive impact on combustion efficiency, energy consumption, and equipment performance. Whether it's an industrial furnace, boiler, or residential heating equipment, a reasonable air intake ensures complete fuel combustion, reduces pollutant emissions, and improves energy utilization. However, existing combustion chambers have significant shortcomings in air intake regulation, making it difficult to meet the diverse needs of actual use.

[0003] Currently, most combustion chambers employ either a fixed air intake structure or an automated air intake regulation system. A fixed air intake structure cannot adjust the airflow according to actual conditions, making it difficult to guarantee optimal combustion when factors such as fuel type, ambient temperature, and equipment load change. For example, in low winter temperatures, a fixed airflow may not provide enough oxygen for complete fuel combustion, leading to incomplete combustion, energy waste, and the generation of significant pollutants. While automated air intake regulation systems can adjust according to preset parameters, they often suffer from high costs and complex maintenance, and in some special operating conditions, they cannot flexibly respond to emergencies or meet specific manual adjustment needs.

[0004] In practical applications, operators often need to manually adjust the air intake based on experience or observation to achieve optimal combustion. For example, when changing to different batches of fuel, the air intake needs to be finely adjusted manually due to differences in fuel quality. However, existing combustion chambers lack convenient and quick external manual adjustment devices, making it difficult for operators to change the air intake according to actual usage conditions, which seriously affects the operating efficiency and stability of the equipment. Therefore, developing a combustion chamber with externally adjustable air intake is urgently needed. This will greatly improve the practicality and adaptability of combustion equipment, reduce energy consumption, and reduce environmental pollution. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a combustion chamber with externally adjustable air volume, which solves the technical problem that existing combustion chambers lack convenient and quick external manual adjustment devices, making it difficult for operators to change the air intake volume according to actual usage conditions, which seriously affects the operating efficiency and stability of the equipment.

[0006] According to one aspect, at least one embodiment of this disclosure provides a combustion chamber with externally manually adjustable airflow, comprising:

[0007] The combustion chamber body, the base, and the intake pipe are provided. The combustion chamber body is mounted on the base, and the intake pipe is located at the intake port of the combustion chamber body.

[0008] The insulation fan, the rectangular box, and the movable connection assembly are provided. The insulation fan is mounted on the base, the rectangular box is fixed on the base, and the movable connection assembly is located between the insulation fan and the air inlet pipe.

[0009] An adjustment component is disposed inside the rectangular box;

[0010] The adjustment component includes an inner layer disposed inside the rectangular box. The inner layer has several openings on its side surface. Arc-shaped grooves are formed on both sides of each opening. A sealing block is rotatably connected to each opening. An adjustment port is formed on the surface of each sealing block.

[0011] As a further technical solution, a driven gear is provided at the upper end of the sealing block, and several driving gears are rotatably connected to the top of the rectangular box, with the driving gears meshing with the driven gear.

[0012] As a further technical solution, a screwing block is provided at the upper end of the drive gear, and a guide block is provided at the upper end of the driven gear. The guide block has the same internal structure as the adjustment port.

[0013] As a further technical solution, the movable connection component includes a rectangular groove, which is formed on the surface of the base. Slide rails are provided on both sides of the rectangular groove, and a slide block is slidably connected between the slide rails. The heat preservation fan is installed on the slide block.

[0014] As a further technical solution, a pair of uprights are provided on the surface of the base, a pair of mating posts are provided on the surface of the slide, and a connecting stud is rotatably connected inside the uprights, with one end of the connecting stud being screwed into the mating post by a thread.

[0015] As a further technical solution, both sides of the rectangular box are provided with docking covers, and the air inlet pipe and the air outlet of the heat preservation fan are respectively inserted into the docking covers. The docking points of the docking covers with the air inlet pipe and the air outlet of the heat preservation fan are all beveled structures.

[0016] As a further technical solution, the opening size of the through-hole matches the opening size of the adjustment port, and the inner width of the arc-shaped groove is greater than the opening width of the adjustment port.

[0017] As a further technical solution, the sealing block has an overall cylindrical structure, and the sealing blocks slide and fit together with each other.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. The beneficial effect of the adjustment component in this disclosure is that its structure is ingeniously designed. By rotating the screw block, the drive gear and the driven gear are driven to rotate the sealing block, thereby changing the connection area between the adjustment port and the through port to adjust the air intake volume. The operator can operate it manually outside the combustion chamber conveniently and quickly to meet the air intake volume requirements under different working conditions and improve combustion efficiency. For example, when the fuel type changes, the air intake volume can be adjusted in time to ensure complete combustion of fuel, reduce energy waste and pollutant emissions. Moreover, the guide block makes it easy for the operator to intuitively judge the change in air intake volume, which enhances the accuracy of adjustment.

[0020] 2. The beneficial effect of the movable connection component in this disclosure is that the combination of the rectangular groove, slide rail, column, docking column and connecting stud can realize the precise docking and fixation of the heat preservation fan and the air intake pipe. The bevel structure of the docking cover ensures the sealing of the docking. During equipment maintenance, simply loosen the connecting stud and the sliding rectangular box can quickly separate the two, which greatly improves the convenience and efficiency of equipment maintenance, avoids the complicated disassembly process in traditional equipment, saves maintenance time and labor costs, ensures the normal operation of the combustion chamber equipment, and extends the service life of the equipment.

[0028] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0029] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-5 As shown, it illustrates a combustion chamber with externally manually adjustable airflow according to an embodiment of the present disclosure, comprising:

[0035] The combustion chamber body 1, the base 2, and the air intake pipe 3 are provided. The combustion chamber body 1 is mounted on the base 2, and the air intake pipe 3 is located at the air intake of the combustion chamber body 1.

[0036] The heat-insulating fan 4, the rectangular box 5, and the movable connecting assembly 7 are provided. The heat-insulating fan 4 is mounted on the base 2, the rectangular box 5 is fixed on the base 2, and the movable connecting assembly 7 is located between the heat-insulating fan 4 and the air inlet pipe 3.

[0037] Adjustment component 6 is disposed inside the rectangular box 5;

[0038] The adjustment component 6 includes an inner layer 6-1, which is disposed inside the rectangular box 5. The inner layer 6-1 has several openings 6-2 on its side surface. Each opening 6-2 has an arc-shaped groove 6-3 on both sides. Each opening 6-2 is rotatably connected to a sealing block 6-4. The surface of the sealing block 6-4 has an adjustment port 6-5. The upper end of the sealing block 6-4 is provided with a driven gear 6-6. The top of the rectangular box 5 is rotatably connected to several driving gears 6-7. The driving gears 6-7 mesh with the driven gears 6-6. The upper end of the driving gears 6-7 is provided with a screwing block 6-8. The upper end of the driven gears 6-6 is provided with a guide block 6-9. The guide block 6-9 has the same internal structure as the adjustment port 6-5.

[0039] In some examples, during the operation of the combustion chamber, in order to flexibly adjust the intake air volume entering the combustion chamber body 1 to adapt to different combustion conditions, an adjustment component 6 is designed. This component includes an inner layer 6-1 set inside the rectangular box 5. Several openings 6-2 on its side surface provide channels for air circulation. Arc-shaped grooves 6-3 on both sides of the openings 6-2 provide space for the rotation of the sealing blocks 6-4. The sealing blocks 6-4 rotatably connected in each opening 6-2 have adjustment ports 6-5 on their surfaces to change the air circulation area. The driven gear 6-6 set at the upper end of the sealing block 6-4 meshes with the drive gear 6-7 rotatably connected to the top of the rectangular box 5. When the operator rotates the screw block 6-8 at the upper end of the drive gear 6-7, the drive gear 6-7 drives the driven gear 6-6 to rotate, thereby causing the sealing block to rotate. The 6-4 rotates around its own axis. By changing the angle of the sealing block 6-4, the relative position of the adjustment port 6-5 and the through port 6-2 changes, thereby adjusting the airflow area and regulating the intake air volume. The guide block 6-9 set on the upper end of the driven gear 6-6 has the same internal structure as the adjustment port 6-5. During adjustment, the rotation angle of the adjustment port 6-5 can be judged by the guide block 6-9, so the degree of air volume after adjustment can be intuitively understood. Through the coordinated work of the inner layer 6-1, through port 6-2, arc groove 6-3, sealing block 6-4, adjustment port 6-5, driven gear 6-6, drive gear 6-7, screwing block 6-8 and guide block 6-9, the adjustment component 6 can easily adjust the intake air volume manually outside the combustion chamber to meet the air supply requirements under different combustion scenarios and ensure a stable and efficient combustion process.

[0040] like Figures 1-5 As shown in the figure, the movable connection component 7 in this embodiment includes a rectangular groove 7-1, which is formed on the surface of the base 2. Slide rails 7-2 are provided on both sides of the rectangular groove 7-1, and a sliding seat is slidably connected between the slide rails 7-2. The heat-insulating fan 4 is mounted on the sliding seat. A pair of uprights 7-3 are provided on the surface of the base 2, and a pair of docking posts 7-4 are provided on the surface of the sliding seat. A connecting stud 7-5 is rotatably fitted inside the uprights 7-3. One end of the connecting stud 7-5 is screwed into the docking post 7-4. A docking cover 7-6 is provided on both sides of the rectangular box 5. The air inlet pipe 3 and the air outlet of the heat-insulating fan 4 are respectively inserted into the docking cover 7-6. The docking points of the docking cover 7-6 with the air inlet pipe 3 and the air outlet of the heat-insulating fan 4 are all beveled structures.

[0041] In some examples, during the maintenance of the combustion chamber equipment, a movable connection assembly 7 is designed to facilitate the quick docking and separation of the insulation fan 4 and the intake pipe 3, thus simplifying equipment inspection and maintenance. This assembly includes a rectangular groove 7-1 on the surface of the base 2. Slide rails 7-2 on both sides of the rectangular groove 7-1 provide guidance and support for the sliding of the rectangular box 5, allowing it to slide smoothly on the base 2. A pair of uprights 7-3 on the surface of the base 2 and a pair of mating posts 7-4 on the surface of the slide block are also included. Connecting studs 7-5 are rotatably fitted inside the uprights 7-3, with one end screwed into the mating post 7-4. Tightening or loosening the connecting studs 7-5 secures the slide block. The rectangular box 5 has mating posts 7-3 on both sides of the slide block... The connecting cover 7-6 has a beveled structure at its connection points with the air inlet pipe 3 and the air outlet of the insulation fan 4, ensuring a tight fit during connection and guaranteeing the airtightness of gas transmission. For maintenance, simply loosen the connecting stud 7-5 and slide the rectangular box 5 along the slide rail 7-2 to quickly separate the insulation fan 4 from the air inlet pipe 3, facilitating inspection and cleaning of the rectangular box 5. Through the coordinated work of components such as the rectangular groove 7-1, slide rail 7-2, column 7-3, connecting column 7-4, connecting stud 7-5, connecting cover 7-6, and beveled structure, the movable connecting assembly 7 enables reliable connection between the insulation fan 4 and the air inlet pipe 3, while also allowing for rapid separation during maintenance. This improves the convenience and efficiency of equipment maintenance and ensures the normal operation of the combustion chamber equipment.

[0042] For example, such as Figure 5 As shown, the opening size of the through port 6-2 matches the opening size of the adjustment port 6-5, and the inner width of the arc groove 6-3 is greater than the opening width of the adjustment port 6-5.

[0043] In some examples, by matching the opening size, the regulating port 6-5 can be fully connected to the inlet 6-2 to maximize the flow of air, and after rotating 90°, the inlet 6-2 can be completely closed.

[0044] For example, such as Figure 5 As shown, the sealing block 6-4 has an overall cylindrical structure, and the sealing blocks 6-4 slide and fit together with each other.

[0045] In some examples, the cylindrical structure allows the sealing block 6-4 to maintain a tight seal during rotation, preventing air leakage.

[0046] In actual use: Depending on the actual situation, first adjust the position of the slide block in the rectangular groove 7-1 by rotating the connecting stud 7-5, so that the heat preservation fan 4 and the air inlet pipe 3 are tightly connected at the docking cover 7-6. Then, if it is necessary to adjust the air intake, the operator rotates the screw block 6-8 on the top of the rectangular box 5, which drives the drive gear 6-7 to rotate. The drive gear 6-7 meshes with the driven gear 6-6, so that the sealing block 6-4 rotates in the through port 6-2, changing the relative position of the adjusting port 6-5 and the through port 6-2, thereby adjusting the air intake. Observing the guide block 6-9 can intuitively understand the rotation angle of the adjusting port 6-5, thereby judging the change in air intake. During equipment maintenance, loosen the connecting stud 7-5, slide the rectangular box 5, and separate the heat preservation fan 4 from the air inlet pipe 3 for maintenance.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
