Description

Technical Field

[0001] This utility model relates to the field of oxygen regulation in lime kilns, and more specifically, to an oxygen regulation device for lime kilns. Background Technology

[0002] Lime kilns are a very broad and important type of industrial equipment, widely used in steel, building materials, chemical, environmental protection, and agriculture industries. Their core function is to produce quicklime by calcining limestone at high temperatures, and in some processes, they are further processed into active lime, lightly calcined dolomite, calcium carbide raw materials, etc.

[0003] However, in the process of lime production in a lime kiln, oxygen needs to be supplied to the kiln through an oxygen delivery system connected to a pipeline. The pipeline is opened or closed by valves, and the flow rate of the oxygen delivery is regulated by the degree of valve rotation. Since the valves are installed on the oxygen delivery pipeline after being drilled through holes, they may age over time, leading to air leaks between the oxygen delivery pipeline and the valves, which could endanger workers. Therefore, a lime kiln oxygen regulating device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the oxygen delivery pipeline is prone to leakage because the valve is installed on the oxygen delivery pipeline later.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides an oxygen regulating device for a lime kiln, comprising an oxygen processing device. A gas transmission pipe is fixedly connected to the surface of the oxygen processing device. A first cover plate and a second cover plate are provided on the surface of the gas transmission pipe.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 An oxygen regulating device for a lime kiln includes an oxygen processing device 1. A gas transmission pipe 2 is fixedly connected to the surface of the oxygen processing device 1. A first cover plate 3 and a second cover plate 4 are provided on the surface of the gas transmission pipe 2. The first cover plate 3 and the second cover plate 4 are fixed together by bolts. A rubber gasket is provided between the first cover plate 3 and the second cover plate 4 for sealing. A second valve 11 is provided inside the gas transmission pipe 2 located inside the first cover plate 3 and the second cover plate 4. A driving structure is provided inside the second cover plate 4. The driving structure includes a moving plate 10. The surface of the moving plate 10 is slidably connected to the inside of the second cover plate 4. An alarm 17 is fixedly connected to the bottom of the second cover plate 4. A control switch 16 is provided inside the second cover plate 4. The control switch 16 and the alarm 17 are electrically connected. Since the oxygen processing device 1 and the alarm 17 are existing known devices, they will not be explained further.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A return spring 15 is fixedly connected inside the second cover plate 4. The end of the return spring 15 away from the second cover plate 4 is fixedly connected to the moving plate 10. The sliding of the moving plate 10 is controlled by the setting of the return spring 15.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The second cover plate 4 is fixedly connected to a limiting rod 14. The surface of the limiting rod 14 is slidably connected to the inside of the moving plate 10. Thus, the sliding of the moving plate 10 is restricted by the setting of the limiting rod 14, thereby reducing the possibility of the moving plate 10 tilting and getting stuck when sliding.

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The surface of the second cover plate 4 is provided with a collection structure, which includes a fixed pipe 6. The fixed pipe 6 is fixedly connected to the surface of the second cover plate 4. A collection box 8 is fixedly connected to the end of the fixed pipe 6 away from the second cover plate 4. A discharge pipe 9 is fixedly connected to the surface of the collection box 8. A first valve 7 is provided on the surface of both the discharge pipe 9 and the fixed pipe 6. The fixed pipe 6 and the discharge pipe 9 are closed by the setting of the first valve 7.

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A rotating rod 5 is rotatably connected inside the first cover plate 3. The rotating rod 5 extends into the interior of the first cover plate 3. A rotating block 12 is fixedly connected to one end of the rotating rod 5 inside the first cover plate 3. A positioning rod 19 is fixedly connected to the bottom of the rotating block 12. A positioning hole 18 is provided at the upper end of the second valve 11. The positioning hole 18 corresponds to the positioning rod 19. The positioning rod 19 is then inserted into the positioning hole 18, which can drive the second valve 11 when the rotating rod 5 is rotated.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A limiting plate 13 is fixedly connected inside the first cover plate 3. The inside of the limiting plate 13 is rotatably connected to the surface of the rotating block 12. Thus, by setting the limiting plate 13, the swaying of the rotating block 12 when the rotating rod 5 drives the rotating block 12 to rotate is reduced.

[0032] The process of using the oxygen regulating device for lime kilns provided by this utility model is as follows: When installing the first cover plate 3 and the second cover plate 4, align the rotating block 12 with the upper end of the second valve 11, and then insert the positioning rod 19 into the positioning hole 18. The second valve 11 can be driven by rotating the rotating rod 5, thereby controlling the second valve 11 and thus controlling the flow rate of oxygen inside the gas pipeline 2.

[0033] When the second valve 11 leaks, oxygen enters the space between the first cover plate 3 and the second cover plate 4 through the gap between the second valve 11 and the gas pipeline 2. Since the first cover plate 3 and the second cover plate 4 are sealed spaces, the oxygen leaks and compresses the moving plate 10. The moving plate 10 moves downward under force and contacts the control switch 16. The movement of the moving plate 10 causes the return spring 15 to deform, which in turn compresses the control switch 16 and activates the alarm 17. The alarm 17 sounds an alarm to remind the staff so that timely maintenance can be carried out and to avoid injury to the staff.

[0034] At the same time, the moving plate 10 moves down and no longer blocks the fixed pipe 6, so that the excess oxygen enters the collection box 8, thereby collecting the leaked oxygen and avoiding the waste of oxygen. It also avoids excessive pressure inside the first cover plate 3 and the second cover plate 4, and can be connected to the discharge pipe 9 through the pipe to export the oxygen collected inside the collection box 8.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; conversely, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
