[0003] The ash discharge valve drives a set of impellers with several blades to rotate through a motor reduction transmission device. When the material in the upper hopper falls by its own weight and fills the gaps between the blades, the material will be discharged as the blades rotate, thus realizing periodic quantitative feeding.

[0004] However, existing ash discharge valve monitoring equipment can only detect the current and voltage signals of the ash discharge valve, which is difficult to directly reflect the actual opening and closing speed of the valve inside the ash discharge valve. Furthermore, when the ash discharge valve is blocked due to dust accumulation, it is difficult to detect the abnormality in time by relying solely on the current and voltage monitoring device. Therefore, it does not meet the existing requirements. In response, we have proposed an ash discharge valve with intelligent speed monitoring. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The ash discharge valve 1 (model YJD), the ash discharge valve drive motor 2 (model DM542), and the tachometer 6 (model HT-3100) mentioned in this utility model can be obtained from the market or through private customization.

[0023] Please see Figures 1 to 4 The present invention provides an embodiment of an ash discharge valve with intelligent speed monitoring, comprising an ash discharge valve 1, an ash discharge valve drive motor 2 mounted on the front end face of the ash discharge valve 1, an output shaft of the ash discharge valve drive motor 2 connected to a drive shaft 3 via a coupling, a cylindrical metal housing 4 fixed to the rear end face of the ash discharge valve 1 on the outer side of the rear end of the drive shaft 3, a tachometer 6 fixedly mounted in the middle position inside the cylindrical metal housing 4, a square tachometer detection head 7 connected to the middle position of the front end face of the tachometer 6, a square slot 5 located in the middle position of the rear end face of the drive shaft 3 on the outer side of the square tachometer detection head 7, and the square tachometer detection head 7 inserted into the interior of the square slot 5.

[0024] The inner wall of the square slot 5 has a square cross-section. The outer surface of the square tachometer head 7 fits against the inner wall of the square slot 5, and the square tachometer head 7 and the square slot 5 are slidably connected. A wireless data transmitter 8 is installed on one side of the lower end face of the tachometer 6, and the wireless data transmitter 8 is connected to the cloud signal for data monitoring. When the motor 2 for driving the ash discharge valve drives the drive shaft 3 to rotate, the square tachometer head 7 inserted in the square slot 5 at the rear end face of the drive shaft 3 will rotate synchronously with the drive shaft 3. Through the rotating square tachometer head 7, the tachometer 6 can monitor in real time the actual operating speed and status of the drive shaft 3 used to drive the ash discharge valve 1, including the valve opening and closing speed, blockage status, and the speed of material flow inside the ash discharge valve 1. This data is transmitted to the cloud via the wireless data transmitter 8. The above technical solution can monitor in real time data that is difficult to capture directly by current and voltage monitoring devices alone. When a blockage occurs inside the equipment, the monitoring personnel can quickly detect the abnormality and dispatch maintenance personnel to carry out maintenance work, thereby improving the protection of the ash discharge valve 1.

[0025] A data display panel 17 is fixedly installed on one side of the outer surface of the tachometer 6. The data display panel 17 extends to the outer surface of the cylindrical metal housing 4 by passing through it. The data display panel 17 allows maintenance personnel to observe the actual operating speed and condition of the drive shaft 3 from the outside.

[0026] A first bevel gear 9 is fixedly sleeved on the outer surface of the drive shaft 3 located inside the cylindrical metal casing 4. The first bevel gear 9 meshes with a second bevel gear 10. The shaft of the second bevel gear 10 is connected to a gear shaft 11. A third bevel gear 12 is fixedly sleeved on the upper side of the outer surface of the gear shaft 11. The third bevel gear 12 meshes with a fourth bevel gear 13. The shaft of the fourth bevel gear 13 is connected to a generator shaft 14. The rear end face of the generator shaft 14 is connected to a small rotary generator 15, which is fixedly installed inside the cylindrical metal casing 4. A small energy storage box 16, which is fixedly installed inside the cylindrical metal casing 4, is located behind the small rotary generator 15. The small energy storage box 16 is connected to the small rotary generator 15 and the tachometer 6 respectively through a power transmission line. The drive shaft 3 rotates during... During the process, the first bevel gear 9, which is fixedly sleeved on the outer surface of the drive shaft 3, and the second bevel gear 10, which meshes with the first bevel gear 9, will rotate together. The rotating second bevel gear 10 can drive the gear shaft 11 connected to the axis of the second bevel gear 10 and the third bevel gear 12, which is fixedly sleeved on the outer surface of the gear shaft 11, to rotate. When the third bevel gear 12 rotates, the fourth bevel gear 13, which meshes with it, and the generator shaft 14 connected to the axis of the fourth bevel gear 13 will rotate synchronously. The rotating generator shaft 14 enables the small rotary generator 15 to generate its own power. This power will be stored inside the small energy storage box 16 to supply the energy consumption of the tachometer 6 during operation. The above technical solution can reduce the overall energy consumption of the equipment during operation.

[0027] The tachometer 6 has a circular cover plate located at the rear end of the cylindrical metal housing 4, and the cylindrical metal housing 4 and the circular cover plate are fixed together by screws. When the tachometer 6 malfunctions, the circular cover plate can be removed. Since the tachometer 6 is connected to the drive shaft 3 through the square slot 5 and the square tachometer detection head 7, the tachometer 6 can be directly pulled out after the circular cover plate is removed. After the maintenance of the tachometer 6 is completed, the square tachometer detection head 7 is inserted into the square slot 5 and the circular cover plate is installed back in its original position. The above technical solution enables quick disassembly and assembly of the tachometer 6, improving the convenience of maintenance of the tachometer 6.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
