[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0017] An electro-hydraulic intelligent double-layer ash discharge valve, combined with Figures 1 to 2 As shown, it includes a valve body 1, which is square and has through ports on the top and bottom respectively. Two partitions 2 are arranged inside the valve body 1 along the length direction. The two partitions 2 are arranged horizontally and located between the two through ports. A valve port 3 is provided on the partition 2, and the valve port 3 is arranged opposite to the through port.

[0018] The valve body 1 is equipped with two electro-hydraulic valve plate assemblies 4, each corresponding to one of the two valve ports 3. These assemblies are used to open and close the corresponding valve ports 3. The electro-hydraulic valve plate assembly 4 includes a main shaft 46, which is rotatably mounted within the valve body 1 and positioned below and to one side of the valve port 3 via a bearing and a bearing seat 47. One end of the main shaft 46 extends beyond the valve body 1 and is connected to a drive mechanism that drives the main shaft 46. A valve plate 49 is mounted on the main shaft 46 via a valve plate crank 48. The valve plate 49 rotates with the main shaft 46 to open and close the valve port 3.

[0019] Specifically, the drive mechanism includes a power pump 41, which is mounted on the outer wall of the valve body 1. The power pump 41 is connected to a telescopic cylinder 43 via a hydraulic oil pipe 42. The telescopic cylinder 43 is mounted on the outer wall of the valve body 1 via a telescopic cylinder bracket 411. The end of the telescopic rod of the telescopic cylinder 43 is provided with a U-shaped seat 44, which is rotatably connected to a spindle crank 45 via a pin. The end of the spindle crank 45 away from the U-shaped seat 44 is connected to the end of the spindle 46 that extends from the valve body 1. A pressure plate 410 is provided at the connection between the spindle 46 and the spindle crank 45. The pressure plate 410 is located outside the spindle crank 45. During use, the telescopic cylinder 43 is controlled to extend and retract through the power pump 41. The extension and retraction of the telescopic cylinder 43 drives the main shaft crank 45 to rotate. The rotation of the main shaft crank 45 drives the main shaft 46 to rotate. The rotation of the main shaft 46 drives the valve plate 49 to rotate. The rotation of the valve plate 49 realizes the opening and closing of the valve port 3. With such a design, ash is not easily stuck between the valve plate 49 and the valve port 3, which can avoid the blockage of the discharge pipe due to air leakage, the damage to the surface of the valve plate 49, the non-sealing of the valve plate 49 plane, and the external leakage problem.

[0020] A silicone ring 6 is provided on the valve port 3 through a clamp 5. The silicone ring 6 is in a bell-mouth shape and contacts the valve plate 49 when the valve plate 49 closes the valve port 3, thereby achieving sealing.

[0021] Two window covers 7 are pivotally connected to the valve body 1. These two covers 7 are positioned opposite the opened valve plate 49, allowing for convenient cleaning and maintenance of the interior of the valve body 1. A wrench 8 is pivotally mounted on the window cover 7 via a wrench locating pin, facilitating opening and closing of the window cover 7. A door lock 9 is provided on the outer wall of the valve body 1, which cooperates with the wrench 8 to securely lock the window cover 7. A sealing ring is also provided on the outer wall of the valve body 1, which seals with the window cover 7 when closed, thereby achieving a seal at the window cover 7.

[0022] When the present invention is in use, the power pump 41 controls the extension and retraction of the telescopic cylinder 43. The extension and retraction of the telescopic cylinder 43 drives the rotation of the main shaft crank 45. The rotation of the main shaft crank 45 drives the rotation of the main shaft 46. The rotation of the main shaft 46 drives the rotation of the valve plate 49. The rotation of the valve plate 49 realizes the opening and closing of the valve port 3. With this design, ash is not easily stuck between the valve plate 49 and the valve port 3. This can prevent the blockage of the feed pipe due to air leakage, the damage to the surface of the valve plate 49, the non-sealing of the valve plate 49, and the external leakage.
