[0002] Annular sleeve kilns are currently the most common type of kiln used both domestically and internationally for the production of quicklime. They have advantages such as environmental protection, safety, and energy saving. When using sleeve kilns, it is necessary to control the input flow of gas, so a gas flow regulating device is required.

[0003] Compared with existing regulating devices, the following defects still exist: the gas volume of the burners in the kiln is controlled by manual valves, which makes it difficult to accurately control the gas flow rate, easily leading to unstable combustion, affecting the thermal efficiency of the sleeve kiln and product quality. Moreover, when the operating conditions change, it is difficult for operators to make timely and accurate adjustments, further aggravating energy waste and instability in the production process, while also increasing the workload of employees.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 2 , Figure 3 and Figure 4 As shown, this utility model is a gas flow regulating device for a sleeve kiln burner. Specifically, it can be quickly disassembled and installed, making it convenient for users to clean and maintain later. It includes a connecting plate 6 at both ends of the automatic regulating valve 5, and a pipe docking plate 7 connected to the gas pipe 8 on both sides of the connecting plate 6. A first limiting groove 9 is opened on the inner side of the pipe docking plate 7, and a first limiting block 10 connected to the connecting plate 6 is provided on the inner side of the first limiting groove 9. A rubber sealing element 11 connected to the connecting plate 6 is provided at the inner end of the pipe docking plate 7.

[0027] In this embodiment, preferably, the connecting plate 6 and the first limiting block 10 are fixedly connected. The connecting plate 6 forms a fitting and rotating engaging structure in the first limiting groove 9 through the first limiting block 10, which enables the connecting plate 6 to be connected and installed with the pipe connecting plate 7.

[0028] In this embodiment, preferably, the pipe docking plate 7 and the rubber seal 11 are connected by adhesive bonding, and the pipe docking plate 7 is connected to the connecting plate 6 by snap-fitting through the rubber seal 11; the upper and lower sides of the inner end of the pipe docking plate 7 are fixed with second limiting blocks 12, and the outer side of the second limiting block 12 is provided with a second limiting groove 13 located inside the connecting plate 6, which can increase the sealing performance under the action of the rubber seal 11, and can increase the snap-fitting state between the pipe docking plate 7 and the connecting plate 6 through the second limiting groove 13.

[0029] In this embodiment, preferably, a limiting lock block 14 is provided on the inner side of the second limiting block 12, and a damping spring 15 is provided on the outer side of the inner end of the limiting lock block 14. The inner end of the damping spring 15 is provided with a movable handle 16 connected to the connecting plate 6. The second limiting block 12 forms a locking rotation structure in the connecting plate 6 through the second limiting groove 13. The diameter of the upper and lower ends of the second limiting groove 13 is larger than the diameter of the front and rear ends. The limiting lock block 14 and the movable handle 16 are fixedly connected. The limiting lock block 14 forms an elastic telescopic structure in the connecting plate 6 through the damping spring 15. The limiting lock block 14 and the second limiting block 12 are connected by a plug-in method, which can make the limiting lock block 14 disengage from the locking state of the second limiting block 12 when the movable handle 16 is pulled outward, and lock it in the opposite way to improve the fastening effect.

[0030] In summary, firstly, the connecting plate 6 is engaged with the inner side of the first limiting groove 9 by the first limiting block 10, and the second limiting block 12 set at the inner end of the pipe connecting plate 7 is engaged with the inner side of the connecting plate 6 by the second limiting groove 13. At this time, rotating counterclockwise by 90° will allow the first limiting block 10 to rotate and engage within the pipe connecting plate 7, and the second limiting block 12 to rotate and engage within the connecting plate 6. The pipe connecting plate 7 is then sealed at the connection point by the adhesive rubber seal 11, thus improving the sealing effect between the connecting plate 6 and the pipe connecting plate 7. The quick installation is achieved by using a limit lock block 14 with a damping spring 15 to form an elastic telescopic structure within the connecting plate 6. The limit lock block 14 and the second limit block 12 are connected by a plug-in connection. This allows for a tight and limited installation between the connecting plate 6 and the pipe docking plate 7 when the movable handle 16 is released. When the movable handle 16 is pulled outward, the limit lock block 14 disengages from the second limit block 12. Rotating 90° clockwise separates the connecting plate 6 from the pipe docking plate 7.

[0031] Example 2

[0032] Reference Figures 1-4 The image shows the second embodiment of this utility model, which specifically combines advanced sensor technology to monitor and automatically adjust the gas flow rate in real time, enabling it to respond quickly and accurately to changes in gas flow rate. The embodiment includes a kiln body 1; a mounting bracket 2 positioned on the front side of the kiln body 1; a PIC remote I / O station 3 mounted on the front end of the mounting bracket 2; a gas nozzle 4 positioned on the right end of the kiln body 1; an automatic regulating valve 5 positioned above the gas nozzle 4; a gas pipe 8 positioned to the left of the automatic regulating valve 5; a pneumatic shut-off valve 17 connected below the gas pipe 8; a manual regulating valve 18 connected below the pneumatic shut-off valve 17; and an orifice plate flow meter 19 connected below the manual regulating valve 18.

[0033] In summary, before installation, shut off the gas supply and vent the gas from the pipeline. Then, adjust the manual regulating valve 18 to the fully open position before installing the automatic regulating valve 5. Ensure that the valve is installed in the correct position and that the inlet and outlet directions match the gas flow direction. Connect the power supply line and control signal line to the corresponding terminals. Connect the gas source pipe and control signal line. The PID module in the PIC remote IO station 3 calculates the control signal based on the deviation between the preset flow value and the actual measured flow signal using its internal algorithm and sends the signal to the automatic regulating valve 5. The automatic regulating valve 5 adjusts its opening degree according to the received control signal, thereby achieving precise automatic control of the gas flow rate.
