[0002] The clinker suspension preheater system of a cement clinker production line is an important part of the cement production process. It mainly undertakes functions such as raw material decomposition and heat exchange. As one of the important main equipment in the whole clinker production line, the performance of the preheater directly affects the production capacity of the whole production line and largely determines the economic benefits of the enterprise and the environmental indicators of the whole factory; among them, the C4 discharge pipe of the preheater is very important. Whether the C4 discharge pipe of the preheater is used normally is related to the output of the whole production line and the environmental indicators. However, the material distributing valve device on the preheater discharge pipe is related to whether the C4 discharge pipe can operate normally and effectively.

[0003] Previously, the material distributing valve usually adopted a manual regulating valve plate, and the material distribution ratio was adjusted by adjusting the position of the valve plate. This method mainly has two disadvantages:

[0004] 1. Manual adjustment cannot achieve precise adjustment.

[0005] 2. There are safety risks in manual adjustment. When the pressure in the pipeline changes too much, the handle may suddenly bounce up, resulting in mechanical injury accidents. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: an electric actuator for a material distribution valve of a preheater discharge pipe of a cement clinker production line, which includes a main pipeline 1, a first branch pipeline 2 and a second branch pipeline 3. The upper ends of the first branch pipeline 2 and the second branch pipeline 3 are connected to the bottom of the main pipeline 1. The first branch pipeline 2 and the second branch pipeline 3 are arranged to bifurcate at equal angles below the main pipeline 1. A hydraulic pushing component 4 is provided on the side wall of the first branch pipeline 2. The output shaft of the hydraulic pushing component 4 is connected to a valve plate component 5. Both ends of the valve plate component 5 are rotatably connected to the middle positions of the first branch pipeline 2 and the second branch pipeline 3. When the valve plate component 5 rotates, it can control the powder ratio. By setting the hydraulic pushing component 4 to push the valve plate component 5, the purpose of adjusting the material distribution ratio is conveniently achieved.

[0024] In this embodiment, the hydraulic pushing component 4 includes a support frame 41, a hydraulic push rod 42 and a hydraulic oil station 43. The side surface of the support frame 41 is fixedly installed on the side surface of the first branch pipeline 2. The hydraulic push rod 42 is fixedly installed on the support frame 41 through a bracket 44. The hydraulic push rod 42 is communicated with the hydraulic oil station 43 through a pipeline. The hydraulic oil station 43 is used to drive the hydraulic push rod 42 to work.

[0025] In this embodiment, the hydraulic push rod 42 is rotatably connected to the bracket 44. When one end of the hydraulic push rod 42 is stressed, the reaction force on the hydraulic push rod 42 during the flipping of the swing arm 51 can be decomposed through rotation.

[0026] In this embodiment, the valve plate component 5 includes a swing arm 51, a swing arm frame 52, a rotating shaft 53 and a valve plate 54. The top end of the swing arm 51 is hinged to the end of the output shaft of the hydraulic push rod 42. The swing arm 51 is installed at the end of the rotating shaft 53. The swing arm frame 52 is fixedly installed on the middle side surfaces of the first branch pipeline 2 and the second branch pipeline 3. Both ends of the rotating shaft 53 are rotatably installed on the swing arm frame 52 and the side walls in the middle of the first branch pipeline 2 and the second branch pipeline 3. The valve plate 54 is fixedly installed on the rotating shaft 53. The hydraulic push rod 42 pushes the swing arm 51 to rotate. When rotating, the valve plate 54 is driven to rotate through the rotating shaft 53. When the valve plate 54 rotates, it can control the communication area between the tops of the first branch pipeline 2 and the second branch pipeline 3 and the communication position with the main pipeline 1, thereby achieving the purpose of adjusting the material distribution ratio.

[0027] In this embodiment, a marking shaft 55 is provided at the root of the swing arm 51. The marking shaft 55 can rotate along with the swing arm 51. By observing the rotation position of the marking shaft 55, the rotation position of the valve plate 54 in the first branch pipeline 2 and the second branch pipeline 3 can be judged.

[0028] In this embodiment, a safety cover 541 is provided on the top of the valve plate 54, which can protect the valve plate 54, reduce the impact on the valve plate 54, and prevent the valve plate 54 from deforming.

[0029] The working principle is as follows: During use, the hydraulic push rod 42 is driven to work by the hydraulic oil station 43. The hydraulic push rod 42 pushes the swing arm 51 to rotate. When rotating, the valve plate 54 is driven to rotate through the rotating shaft 53. When the valve plate 54 rotates, the communication areas between the tops of the first branch pipe 2 and the second branch pipe 3 and the communication positions of the main pipe 1 can be controlled respectively, so as to achieve the purpose of adjusting the material distribution ratio.

[0030] Based on the above, the present utility model provides a new material distribution valve actuator. By setting the hydraulic push rod, the angle of the valve plate can be adjusted conveniently and controllably, reducing the risk of manual turning.
