[0002] The electric ash discharge valve is generally made of casting or welded carbon steel plates. It is one of the main equipment for discharging ash from dust removal equipment and other equipment. The electric ash discharge valve is divided into normal temperature type and high temperature type, which is composed of a motor, a differential planetary reducer or a pinwheel cycloidal reducer and a rotary dragon type discharger; the electric ash discharge valve has the functions of real-time air locking and ash discharging. When a dust explosion occurs, it can prevent the flame and air wave from overflowing and causing casualties, and at the same time, it can empty the dust in the ash hopper in real time to reduce the risk of secondary dust explosion. At present, the blades inside the explosion-proof electric ash discharge valve are integrally formed or welded with the rotating rod. After long-term use, the blades are easily worn, so the whole impeller needs to be replaced, which increases the cost to a certain extent. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0028] Refer to Figures 1 - 6 , the explosion-proof electric ash discharge valve includes a valve body 1. Feed ports and discharge ports are respectively opened at the upper and lower ends of the valve body 1. And a motor 2 is installed on the side of the valve body 1, and the output end of the motor 2 is connected to a rotating rod 3; the rotating rod 3 penetrates into the valve body 1, and grooves 4 are annularly and equidistantly opened on the surface of the valve body 1. And a rotating plate 5 is arranged inside the groove 4, and a fixing hole 6 is opened on one side of the rotating plate 5; a sleeve 7 is sleeved on the surface of the rotating rod 3 outside the valve body 1, and a first chute 8 is opened on the inner wall of the sleeve 7. A first slider 9 is slidably connected inside the first chute 8, and a connecting rod 10 is connected to one side of the first slider 9; connecting grooves 11 are annularly and equidistantly opened on the surface of the rotating rod 3 outside the valve body 1, and the connecting rod 10 passes through the connecting groove 11 and is connected to a connecting plate 12. A fixing rod 13 is connected to one side of the connecting plate 12, and the fixing rod 13 passes through the groove 4 and is in contact with the inside of the fixing hole 6. By moving the sleeve 7, the connecting rod 10 connected thereto can drive the connecting plate 12 and the fixing rod 13 to move, so that the fixing rod 13 passes through the groove 4 and is in contact with the inside of the fixing hole 6 on the surface of the rotating plate 5, thereby the rotating plate 5 can be fixed inside the groove 4. Conversely, it is also convenient to disassemble it for replacement or maintenance, etc.

[0029] Furthermore, the inner diameter of the sleeve 7 is the same as the diameter of the rotating rod 3, and the diameter of the connecting rod 10 is the same as the width of the connecting groove 11; the cross-sectional area of the rotating plate 5 is the same as the cross-sectional area of the groove 4, and the diameter of the fixing rod 13 is the same as the inner diameter of the fixing hole 6, which is to avoid gaps between them, resulting in deviation or movement.

[0030] Further, a limiting plate 14 is connected to one side of the sleeve 7. A partition plate 15 is fixedly connected to the surface of the rotating rod 3. An annular plate 16 is movably sleeved on the surface of the rotating rod 3. A rack 17 is connected to the inner wall of the annular plate 16. A gear 18 is connected to the surface of the rack 17. A screw rod 19 that is threadedly connected between the partition plate 15 and the limiting plate 14 is connected to the center of the gear 18. By rotating the annular plate 16, it can move on the surface of the second slider 21 through the second chute 20, so that the rack 17 moves on the surface of the gear 18, driving the screw rod 19 to rotate. Since the screw rod 19 is threadedly connected to the surface of the partition plate 15, it can rotate and move, so as to move the screw rod 19 into the threaded hole on the surface of the limiting plate 14, thereby fixing the limiting plate 14 and the sleeve 7, etc.

[0031] Further, a second chute 20 is opened at the bottom end inside the annular plate 16.
