Description

[0002] In the industrial production process, especially in the combustion control of the boiler furnace, the regulation of oxygen content has a crucial influence on the combustion efficiency and energy utilization. The boiler furnace, i.e. the hearth, in the combustion process of the hearth, maintaining an appropriate amount of air intake is a key factor to ensure the full combustion of coal powder or other fuels. The size of the air quantity is directly related to the thermal efficiency of the combustion process and the emission of harmful gases. If the amount of air supplied for combustion in the hearth is too large, part of the oxygen will not fully react with the fuel, but will be discharged from the chimney as hot flue gas. This not only increases the flue gas heat loss and reduces the operating economy of the boiler, but also may cause environmental pollution. On the contrary, if the amount of air supplied for combustion in the hearth is too small, the fuel will not be fully combusted, and the incomplete combustion will produce harmful gases such as methane and carbon monoxide.

DETAILED DESCRIPTION

[0029] The specific embodiments of the utility model are described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0030] The utility model relates to a kind of rotating oxygen concentration regulating device, as shown in Figures 1 to 5 It includes:

[0031] Mounting part 1, as the basic component of entire device, is provided with cylindrical cavity, and the one end slot of mounting part 1 cavity is communicated with shaft furnace air inlet hole, and the other end of mounting part 1 cavity is communicated with air blower, to ensure that gas can flow smoothly;

[0032] Mounting ring 2 is installed in the cavity inside mounting part 1, and is slidably installed along the length direction of cavity;

[0033] Connecting ring 3 is rotatably installed on mounting ring 2, and connecting ring 3 is connected with the cavity wall of mounting part 1;

[0034] Two baffles 4 are fixedly installed on connecting ring 3 and mounting ring 2 respectively, and two baffles 4 are rotatably connected, two ventilation holes of 90 ° are provided on baffle 4, and two ventilation holes on baffle 4 are arranged in axial symmetry, and the design of ventilation hole is to realize different ventilation area combination when baffle 4 relatively rotates, to adjust the oxygen concentration entering shaft furnace;

[0035] Bolts 5 are installed in threaded holes of the mounting member 1 and are connected with the mounting ring 2, and are used to lock the connection position of the mounting ring 2 and the mounting member 1, and by tightening or loosening the bolts 5, the mounting ring 2 can be fixed or released, so as to facilitate adjustment and maintenance;

[0036] The drive mechanism 6 is arranged on the mounting member 1, and provides rotational power to the connecting ring 3 to adjust the overlapping area of the air holes of the two baffle plates 4;

[0037] The working principle of the device is as follows:

[0038] When it is necessary to increase or decrease the oxygen concentration in the shaft furnace, the operator only needs to start the drive mechanism 6 to make the connecting ring 3 rotate together with the baffle plate 4 on it relative to the other baffle plate 4 fixed on the mounting ring 2, so as to change the size of the overlapping part of the air holes on the two baffle plates 4, and finally realize accurate control of the oxygen flow rate and concentration;

[0039] The control device can flexibly adjust the oxygen flow rate and concentration according to actual needs, ensure the adaptability of oxygen supply in the chemical reaction process, improve the production efficiency and product quality, and at the same time, the device has a compact and reasonable structure, is easy to operate and maintain, the design of sliding and rotating parts simplifies the adjustment process, improves the response speed of the system, and the bolt 5 locking mechanism further ensures the stability of the device in the non-adjustment state, reduces unnecessary energy loss, and the overall scheme not only meets the requirements of accurate control of oxygen concentration in industrial production, but also reduces the complexity and operating cost of the equipment, has significant economic benefits and application prospect.

[0040] As a preferred scheme, as shown in Figures 1 to 5 The drive mechanism 6 comprises:

[0041] The mounting seat 61 is arranged on the mounting member 1;

[0042] The drive motor 62 is arranged on the mounting seat 61, and a fan-shaped gear 63 is mounted on the output end of the drive motor 62;

[0043] The transmission gear 64 is installed in the fixed groove of the connecting ring 3, and the transmission gear 64 is coincident with the rotation axis of the connecting ring 3, and the fan-shaped gear 63 is engaged with the transmission gear 64 through the through hole of the mounting member 1;

[0044] The intermittent meshing design of the sector gear 63 and the transmission gear 64 ensures that the connecting ring 3 and the baffle 4 can be precisely adjusted in angle, so as to realize the fine regulation of the oxygen flow rate and concentration. This design not only improves the accuracy of the regulation, but also ensures that the feedback time is reserved for the oxygen supply in the shaft furnace after the connecting ring 3 is adjusted to a working position. The compact layout of the driving motor 62 and the gear set simplifies the overall structure, enhances the stability and reliability of the system, and makes the operation more convenient and the maintenance easier.

[0045] As a preferred solution, as shown in Figures 2 to 4 The output end of the driving motor 62 is coaxially installed with the limiting piece 65, which is coaxial with the sector gear 63.

[0046] A plurality of circular arc grooves are equidistantly arranged on the outer wall of the transmission gear 64. The size and spacing of the circular arc grooves are adapted to the shape and stroke of the limiting piece 65. Each circular arc groove corresponds to a preset angle position of the baffle 4, so as to realize the step-by-step regulation of the oxygen flow rate and concentration. The limiting piece 65 is slidably connected with the circular arc groove of the transmission gear 64 through the through slot of the mounting piece 1.

[0047] When the sector gear 63 meshes with the transmission gear 64, the limiting piece 65 is in a disengaged state with the circular arc groove of the transmission gear 64.

[0048] The working principle of the driving mechanism 6 of the device is as follows:

[0049] When it is necessary to adjust the oxygen concentration in the shaft furnace, the operator starts the driving motor 62, so that the sector gear 63 rotates and meshes with the transmission gear 64. With the rotation of the sector gear 63, it transmits driving force to the transmission gear 64, and then makes the connecting ring 3 and the baffle 4 thereon rotate relative to the other baffle 4 on the mounting ring 2. In this process, the limiting piece 65 remains in a disengaged state with the circular arc groove, ensuring smooth rotation of the connecting ring 3. When the connecting ring 3 rotates to the predetermined angle position, the sector gear 63 meshes with the transmission gear 64. Then, the limiting piece 65 quickly slides into the adjacent circular arc groove, effectively locking the position of the connecting ring 3, preventing unnecessary displacement due to external factors.

[0050] The precise step-by-step regulation of the angle position of the baffle is realized by the cooperation of the limiting piece 65 and the circular arc groove, ensuring that the oxygen flow rate and concentration can be stably adjusted according to the preset standard. The limiting piece 65 remains in a disengaged state during the meshing of the sector gear 63 and the transmission gear 64, without affecting the smoothness of the rotation process. After reaching the predetermined angle, it quickly slides into the corresponding circular arc groove to provide immediate locking function, avoiding position deviation caused by external interference, and enhancing the reliability and safety of the system.

[0051] As a preferred solution, as shown in Figure 1As shown, the mounting component 1 is provided with an isolation component 66, and the sector gear 63 and the limiting component 65 are located inside the isolation component 66;

[0052] The isolator 66 provides a closed working environment for the key components of the drive mechanism, effectively protecting the sector gear 63 and the limiter 65 from external dust, impurities, and accidental impacts, thereby improving the service life and operational reliability of these precision components.

[0053] As a preferred option, such as Figures 1 to 4 As shown, an isolation net 21 is provided in the installation ring 2, and the isolation net 21 is located on the side where the blower is installed;

[0054] The isolation net 21 effectively prevents large particles of impurities and foreign objects from entering the device from the blower side, protecting the key components of the rotary oxygen concentration control device from potential damage and ensuring the long-term stable operation of the system. At the same time, the isolation net 21 helps maintain the cleanliness of the cavity, preventing dust and other tiny particles from accumulating around the ventilation holes of the baffle plate 4, and avoiding the impact of blockage on the precise adjustment of oxygen flow rate and concentration.

[0055] As a preferred option, such as Figures 3 to 5 As shown, a shaft hole is provided in the middle of the baffle plate 4, and a positioning shaft 41 is installed in the shaft holes of the two baffle plates 4;

[0056] The positioning shaft 41 ensures a stable connection and precise relative rotation between the two baffles 4, allowing the baffles 4 to maintain axial symmetry during rotation. This enables precise control of the overlapping area of ​​the ventilation holes, ensuring accurate adjustment of oxygen flow rate and concentration. At the same time, the presence of the positioning shaft 41 improves the overall structural strength of the device, enhances the reliability and durability of the system, and prevents baffle misalignment caused by long-term operation or external vibration.

[0057] As a preferred option, such as Figure 1 and Figure 2 As shown, the mounting component 1 is provided with a fixing plate 11 on the mounting side of the vertical furnace, and the fixing plate 11 is provided with through holes for assembly;

[0058] The mounting plate 11 provides a stable installation foundation for the rotary oxygen concentration control device, ensuring precise positioning and secure fixation of the device on the vertical furnace, enhancing the stability and reliability of the entire system. Assembly is carried out through the through holes on the mounting plate 11, simplifying the installation process and improving installation efficiency. At the same time, it allows for quick connection and disassembly using standard fasteners, facilitating maintenance and repair.

[0059] The rotary oxygen concentration control device of this utility model can be installed, connected, or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0060] The above are only preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present application.
