[0032] As described in more detail in this embodiment, a rotating shaft 141 is provided inside the raw material lifting cylinder 140, and an auger 142 is spirally mounted on the outside of the rotating shaft 141. The upper and lower ends of the rotating shaft 141 are supported by bearings at the upper and lower ends of the raw material lifting cylinder 140.

This facilitates the assembly of the raw material lifting cylinder 140 and the coarse slag lifting cylinder 150 during use, and facilitates the lifting and conveying of raw materials and substandard materials by the raw material lifting cylinder 140 and the coarse slag lifting cylinder 150 respectively, ensuring stable subsequent use.

This facilitates the auxiliary support assembly of the horizontal drive shaft 163, the second rotating shaft 151, and the first rotating shaft 141, making the subsequent transmission more stable and convenient.

[0033] As described in more detail in this embodiment, both the raw material feed hopper 143 and the coarse slag feed hopper 153 are wide-mouthed. Both the raw material discharge pipe 144 and the coarse slag discharge pipe 154 are inclined at different heights, with the ends of the raw material discharge pipe 144 and the coarse slag discharge pipe 154 closest to the outer walls of the raw material elevator cylinder 140 and the coarse slag elevator cylinder 150 respectively being higher. A raw material pipe cover 145 is provided on the top of the feed channel 101, with the upper end of the raw material pipe cover 145 fitted over the lower end of the raw material discharge pipe 144. The lower end of the coarse slag channel 102 is aligned with the coarse slag discharge point. The outer wall of the connector 155 is fastened with screws, and a discharge sleeve 156 is installed at the lower outlet of the coarse slag discharge connector 155. The lower end of the discharge sleeve 156 is inserted into the coarse slag feed hopper 153. This facilitates the feeding of the lower part of the raw material lifting cylinder 140 and the coarse slag lifting cylinder 150 and the discharge of the upper part of the raw material lifting cylinder 140 and the coarse slag lifting cylinder 150, making the conveying operation more convenient. With the cooperation of the raw material pipe cover 145, it is easy to assist in the relative sealing and prevent it from falling from the top.

[0034] As described in more detail in this embodiment, the upper end of the receiving hopper 120 is integrally provided with an arc-shaped upward auxiliary side cover 121, and the lower end of the receiving hopper 120 is integrally provided with a connecting discharge pipe 122. The lower end of the discharge pipe 122 is inserted into the upper end of the stable flow silo 130. The upper end of the stable flow silo 130 is covered with an auxiliary cover 123, and the upper end of the auxiliary cover 123 is fitted and assembled on the outer wall of the lower end of the coarse slag outlet pipe 154 and the discharge pipe 122. This facilitates the auxiliary reception of raw materials transmitted by the conveying device, facilitates the guiding of material feeding into the stable flow silo 130, and facilitates the maintenance of the top of the stable flow silo 130. The lower end of the stable flow silo 130 is equipped with a discharge valve 131, and the lower end of the discharge valve 131 is equipped with a discharge soft sleeve 132. The discharge soft sleeve 132 is inserted into the discharge funnel 170. This facilitates the auxiliary discharge and limiting sealing of the bottom of the stable flow silo 130, making subsequent material discharge more convenient.

[0035] As a more detailed embodiment, the top side of the feeding hopper 170 is integrally fixed with a corresponding side support plate 172. A limiting pin 173 is inserted through the side of the side support plate 172, and the lower end of the limiting pin 173 is fixed to the surface of the supporting side plate 112. The upper end of the limiting pin 173 is fastened by a nut, and a spring 174 is sleeved on the outer wall of the limiting pin 173. Two sets of springs 174 are located above and below the side support plate 172, which facilitates the limiting support of the feeding hopper 170 during assembly and use, and also facilitates subsequent vibration discharge. A vibrator 171 is installed and supported on the outer wall of the side of the feeding hopper 170, and a feeding hose 175 is fixedly installed at the bottom of the feeding hopper 170. The feeding hose 175 is inserted into the upper part of the raw material feed hopper 143, which facilitates the auxiliary vibration of the feeding hopper 170, making it easier to vibrate and prevent accumulation during intermediate material receiving, and making the feeding of raw material feed hopper 143 more convenient.

[0036] Working principle: With the cooperation of the support frame 110 and related support brackets, the stable flow silo 130, raw material lifting cylinder 140, and coarse slag lifting cylinder 150 are supported and assembled. Simultaneously, with the cooperation of the drive mechanism 160, the stable flow silo 130 and raw material lifting cylinder 140 are driven and assembled, making subsequent drive operations more convenient. In use, the receiving hopper 120, with the cooperation of the auxiliary side cover 121, receives the raw material transmitted by the conveying device. Then, with the cooperation of the discharge pipe 122 and the auxiliary cover 123, it is guided into the stable flow silo 130. With the sealing of the discharge valve 131, the stable flow is easily controlled. The material is concentrated inside the material hopper 130. After a certain amount is stored, the material is discharged into the material hopper 170 through the opening of the discharge valve 131 and the cooperation of the discharge sleeve 132. Then, with the cooperation of the discharge hose 175, the material is guided into the raw material feed hopper 143. When discharging material in the material hopper 170, the vibration of the vibrator 171, under the elastic force of the side support plate 172, the limit sliding pin 173 and the spring 174, makes the material hopper 170 easy to vibrate and shake to discharge material, avoiding blockage at the bottom of the material hopper 170, making the discharge more convenient. Furthermore, in the drive mechanism 160... Driven by the motor, the rotating shafts 141 and 151 inside the raw material lifting cylinder 140 and the coarse slag lifting cylinder 150 rotate synchronously, thereby driving the screw conveyors 142 and 152 to lift the material in cooperation with the raw material lifting cylinder 140 and the coarse slag lifting cylinder 150. Specifically, the raw material is lifted to the upper end of the raw material lifting cylinder 140 by the screw conveyor 142, and then transported to the cement vertical mill 100 for crushing and grinding through the feed channel 101 with the cooperation of the raw material outlet pipe 144. After falling inside the mill and passing through the internal screen, qualified material is discharged through the discharge chute for use, while unqualified coarse slag material is discharged through the internal screen. The coarse slag is discharged into the coarse slag feed hopper 153 through the coarse slag channel 102 with the cooperation of the coarse slag feeding connector 155 and the discharge soft sleeve 156. Then, with the cooperation of the screw conveyor 152 and the coarse slag lifting cylinder 150, it is lifted to the top and discharged into the stable flow silo 130 through the coarse slag discharge pipe 154. After being remixed with the raw materials entering the stable flow silo 130, it will be re-entered into the cement vertical mill 100 for further grinding. This makes the operation more convenient and facilitates the transition and stable feeding during feeding and the re-lifting and feeding of unqualified coarse slag materials. The operation ends here.

[0037] It should be noted that in this application, the internal and external settings and principles of the cement vertical mill 100, the use of the vibrator 171, and the specific connection structure between components are all prior art and common knowledge to those skilled in the art. They can be implemented through various methods, and no other special requirements are made in this application.
