DETAILED DESCRIPTION

[0035] Embodiment one:

[0036] As Figures 1-3As shown, the ash discharge valve structure given in this example includes an ash discharge pipe 1, a fixed box 18 fixedly installed on the outer surface of the ash discharge pipe 1, a fixed sleeve 3 and a cylinder 11 fixedly installed inside the fixed box 18. A valve body 2 is fixedly installed on the inner surface of the ash discharge pipe 1. A rotating rod 4 is rotatably installed on the inner surface of the fixed sleeve 3. A rotating block 5 is fixedly installed on the outer surface of the rotating rod 4. The other end of the rotating block 5 away from the rotating rod 4 is fixedly installed with a connecting rod 6.

The rotating rod 4 extends to the other end of the fixed box 18 and is fixedly installed with a connecting arm 8. The other end of the connecting arm 8 away from the rotating rod 4 is rotatably installed with a connecting block 9.

[0037] Combined with Figure 4 and Figure 5 As shown, in some embodiments of this example, a fixed block 10 is provided at the other end of the connecting block 9 in the ash discharge valve structure away from the rotating rod 4, and the fixed block 10 is fixedly installed on the output shaft of the cylinder 11. Thus, when it is necessary to control the opening or closing of the ash discharge valve, the cylinder 11 is started, and the output shaft of the cylinder 11 expands and contracts, driving the connected fixed block 10 to move. The fixed block 10 then drives the connecting block 9 to move. Through the precise drive of the cylinder 11, accurate control of the valve opening and closing actions can be achieved, which is more stable and efficient than manual operation. The valve opening can be accurately adjusted according to the actual ash discharge requirements, effectively controlling the ash discharge amount and ash discharge speed, reducing human operation errors and labor intensity.

[0038] In some embodiments of this example, a support block 12 is fixedly installed on the outer surface of the ash discharge pipe 1 in the ash discharge valve structure. A limit frame one 13 with a "U" - shaped cross - section is fixedly installed on the outer surface of the support block 12, and the limit frame one 13 is adapted to the cylinder 11. The provided limit frame one 13 provides stable support and positioning for the cylinder 11, preventing the cylinder 11 from shifting or shaking due to factors such as vibration and external force impact during operation, ensuring the accuracy of the movement of the output shaft of the cylinder 11, thus ensuring the reliability of valve control, extending the service life of the cylinder 11 and the entire valve structure, and making the entire ash discharge valve structure more stable and compact, which is beneficial for normal operation under complex working conditions.

[0039] In some embodiments of the present application, the cylinder 11 in the ash valve structure is fixedly installed with an extension block 14 away from the other end of the output shaft, the extension block 14 is fixedly installed with a mounting rack 15 away from the other end of the cylinder 11, the mounting rack 15 is fixedly installed with a limiting rack two 16 away from the other end of the extension block 14, and the outer surface of the limiting rack two 16 is provided with a fixing bolt 17. The extension block 14 and the mounting rack 15 play a connecting and transitional role, which facilitates the installation of the cylinder 11 at a suitable position and the adjustment of the angle of the cylinder 11, the limiting rack two 16 further enhances the fixing effect of the cylinder 11, and cooperates with the limiting rack one 13 to limit the degrees of freedom of the cylinder 11 from multiple directions, so that the cylinder 11 can remain stable under various working conditions. The fixing bolt 17 can flexibly select a fixing point according to the actual installation environment, improve the adaptability and flexibility of the installation of the entire valve structure, and ensure the reliability and stability of the driving of the cylinder 11 to drive the valve to act.

[0040] Embodiment two:

[0041] The present application further provides an optimized scheme on the basis of the scheme of embodiment one.

[0042] Referring to Figures 6 to 8 , in the constituting scheme of the ash valve structure provided in embodiment one, a fixed seat 19 is fixedly installed away from the other end of the ash pipe 1 on the fixed box 18, and a rotating shaft 20 is arranged on the outer surface of the rotating rod 4.

[0043] In this structure, the rotating shaft 20 ensures the smoothness of the rotation of the rotating rod 4, so that when the cylinder 11 drives the connecting block 9 to drive the rotating rod 4 to rotate, the rotating process is stable and has no jamming, and the power can be accurately transmitted to the ash cover 7 to realize reliable opening and closing of the valve and improve the working efficiency and reliability of the valve structure.

[0044] In combination with Figure 2 and Figure 3 , the present application is fixedly installed with a protective plate 21 on the outer surface of the fixed box 18, and the cross section of the protective plate 21 is in the shape of an "L" letter. After the fixed box 18 is installed, the protective plate 21 is fixed on the outer surface of the fixed box 18, and the protective plate 21 can effectively prevent external objects from colliding and impacting the fixed box 18 and its internal components, thereby playing a protective role.

[0045] In combination with Figure 7As shown, the example is provided with a sealing gasket 22 on the outer surface of the valve body 2, the sealing gasket 22 is a rubber sealing gasket, and the ash removal cover 7 is matched with the valve body 2. The rubber sealing gasket 22 here has good elasticity and sealing performance, when the ash removal cover 7 is closed, the sealing gasket 22 is deformed by being extruded between the ash removal cover 7 and the valve body 2, filling the tiny gap between the two, effectively preventing the material in the ash removal pipe 1 from leaking, ensuring the sealing of the ash removal process, reducing material waste and environmental pollution, improving the safety and environmental protection of the ash removal operation, and also avoiding the entry of external air, moisture and the like into the ash removal pipe 1, affecting the material quality.

[0046] In combination Figures 1 to 8 As shown, based on the above example scheme, the ash valve structure formed in the specific use, the cylinder 11 as a power source, its output shaft stretches to drive the valve action. When it is needed to open the valve to unload ash, the output shaft of the cylinder 11 is stretched out, since the fixed block 10 is fixed on the output shaft of the cylinder 11, the fixed block 10 is connected with the connecting block 9, and the connecting block 9 is connected with the connecting arm 8 of one end of the rotating rod 4, so with the movement of the output shaft of the cylinder 11, the connecting block 9 is driven to move, and then the rotating rod 4 rotates around the rotating shaft 20 in the fixed sleeve 3.

[0047] When the rotating rod 4 rotates, the rotating block 5 fixed on the outer surface thereof rotates, the rotating block 5 drives the ash removal cover 7 to move through the connecting rod 6, when the rotating rod 4 rotates by a certain angle in the corresponding direction, the ash removal cover 7 will move away from the valve body 2, so that the inside of the ash removal pipe 1 is communicated with the outside, and the material can flow out of the ash removal pipe 1, realizing the ash removal operation.

[0048] When it is needed to close the valve to stop unloading ash, the output shaft of the cylinder 11 is retracted, and each component is driven to move in the reverse direction according to the above transmission path, so that the ash removal cover 7 returns to the position tightly combined with the valve body 2, the rubber sealing gasket 22 on the outer surface of the valve body 2 will be deformed due to extrusion when the ash removal cover 7 is combined with the valve body 2, filling the tiny gap between the two, forming a good sealing effect, effectively preventing the material in the ash removal pipe 1 from leaking and external air, moisture and the like from entering the pipe, ensuring the sealing, safety and material quality of the ash removal operation.

[0049] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
