[0002] High-carbon fly ash is a fine ash collected from the flue gas after coal combustion. Fly ash is a major solid waste discharged from coal-fired power plants. With the development of the power industry, the amount of fly ash emitted by coal-fired power plants has been increasing year by year, becoming one of the largest industrial waste residues in my country. However, fly ash can be utilized as a resource, such as as an admixture in concrete. When reusing fly ash, there are requirements for its fineness, which requires grinding to reduce the fly ash to a finer particle size. Existing grinding equipment can only grind fly ash of a specified coarseness. Processing fly ash of different coarsenesses often requires disassembling the equipment and replacing different types of grinding discs, which is cumbersome. Therefore, we propose a high-carbon fly ash raw material grinding equipment. Utility Model Content

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses a high-carbon fly ash raw material grinding device. A grinding ring 101 is fixedly connected to the inner wall of the outer shell 100. The grinding ring 101 cooperates with the grinding disc 105 to facilitate grinding of the raw material. A hydraulic cylinder 102 is fixedly connected to the bottom wall of the outer shell 100, which facilitates the movement of a support frame 103. The extension end of the hydraulic cylinder 102 is fixedly connected to the support frame 103, which supports a rotating rod 104. The bottom wall of the inner cavity of the support frame 103 is rotatably connected to the rotating rod 104, which drives the grinding disc 105 to rotate. The top end of the rotating rod 104 is fixedly connected to the grinding disc 105, which facilitates the grinding of the raw material. The grinding ring 101... The distance between the grinding disc 105 and the grinding wheel gradually decreases, and the gradually decreasing distance allows the raw material to be ground to a suitable coarseness. A motor 106 is fixedly connected to the bottom wall of the outer casing 100, which facilitates the rotation of the transmission rod 107. The output end of the motor 106 is fixedly connected to the transmission rod 107, which facilitates the rotation of the thick gear 108. The outer wall of the transmission rod 107 is fixedly connected to the thick gear 108, which facilitates the rotation of the lifting gear 109. The outer wall of the rotating rod 104 is fixedly connected to the lifting gear 109, which facilitates the rotation of the rotating rod 104. The thick gear 108 meshes with the lifting gear 109. A dust discharge port is provided on the right side wall of the outer casing 100.

[0021] In this embodiment: High-carbon fly ash raw material is fed into the inner cavity of the outer shell 100 from the top. The motor 106 drives the transmission rod 107 to rotate, which in turn drives the thick gear 108 to rotate. The thick gear 108 drives the lifting gear 109 to rotate, which in turn drives the rotating rod 104 to rotate. The rotating rod 104 then drives the grinding disc 105 to rotate. The grinding disc 105, in conjunction with the grinding ring 101, grinds the high-carbon fly ash raw material. When grinding fly ash of different coarseness, the hydraulic cylinder 102 drives the support frame 103 to rise and fall. The support frame 103 drives the rotating rod 104 to rotate, which in turn drives the grinding disc 105 to rise and fall. This allows for easy adjustment of the distance between the grinding disc 105 and the grinding ring 101, thereby grinding fly ash of different coarseness. This device allows for easy adjustment of the distance between the grinding disc 105 and the grinding ring 101, facilitating the processing of high-carbon fly ash of different coarseness and improving the practicality of the device.

[0022] A support rod 110 is fixedly connected to the top wall of the grinding disc 105. The support rod 110 facilitates the rotation of the guide auger 111. The outer wall of the support rod 110 is fixedly connected to the guide auger 111, which facilitates the pushing of raw materials.

[0023] In this embodiment: the grinding disc 105 drives the support rod 110 to rotate, and the support rod 110 drives the guide auger 111 to rotate. The guide auger 111 facilitates the pushing of fly ash raw materials, which makes it easier for the device to push the fly ash raw materials into the inner cavity of the outer shell 100, avoids the raw materials from being blocked, and is conducive to the grinding operation of fly ash.

[0024] A guide ring 112 is fixedly connected to the bottom wall of the grinding disc 105. The guide ring 112 facilitates the flow of the ground fly ash. A baffle ring 113 is fixedly connected to the bottom wall of the outer shell 100. The baffle ring 113 facilitates the blocking of fly ash. The outer wall of the baffle ring 113 is inclined, which facilitates the discharge of fly ash.

[0025] In this embodiment: the guide ring 112 facilitates the flow of the ground fly ash, and the baffle ring 113 separates and blocks the falling fly ash, making it easy to collect and store the fly ash for subsequent discharge and collection.

[0026] A ash-pushing plate 114 is fixedly connected to the bottom wall of the grinding disc 105. The ash-pushing plate 114 facilitates the movement of fly ash, and it is matched with the ash-blocking ring 113.

[0027] In this embodiment: the grinding disc 105 drives the ash pusher 114 to rotate, and the ash pusher 114 pushes the falling fly ash, which is convenient to move the fly ash to the ash discharge port for discharge, and facilitates the subsequent collection of fly ash.

[0028] The top wall of the support frame 103 is evenly provided with rotating grooves, and the inner wall of each rotating groove is rotatably connected with a rotating ball 115. The rotating ball 115 facilitates the support of the grinding disc 105. The rotating ball 115 is located on the bottom wall of the grinding disc 105.

[0029] In this embodiment: the support frame 103 facilitates the support of the rotating ball 115, and the rotating ball 115 supports the grinding disc 105, which facilitates the support of the grinding disc 105, prevents the grinding disc 105 from deflecting, and improves the stability of the device.
