[0024] like Figures 1 to 4As shown, the utility model provides a device for feeding large-sized solid waste to cement kiln tail, comprising an upper feeding box 1 and a machine-side control box 10. A feeding port 13 is provided at the front end of the upper feeding box 1, and a sealing door 4 is provided at the feeding port 13, so that the upper feeding box 1 is a fully sealed box body on all sides.

[0025] A first pneumatic gate valve 11 is provided at the bottom of the upper feed box 1, and a flange is provided between the upper feed box 1 and the first pneumatic gate valve 11. The first pneumatic gate valve 11 is connected to the intermediate feed box 3 through the first flange, and the intermediate feed box 3 is connected to the second pneumatic gate valve 12 through the second flange. The lower end of the second pneumatic gate valve 12 is connected to one end of the feeding chute 5, and the other end of the feeding chute 5 is welded to one end of the feeding straight pipe 6, and the other end of the feeding straight pipe 6 is connected to the processing device 9. The feeding chute 5, the feeding straight pipe 6 and the processing device 9 are interconnected, and the solid waste enters the processing device 9 through the feeding chute 5 and the feeding straight pipe 6. The processing device 9 is connected to a cleaning and blowing pipeline 7, and the cleaning and blowing pipeline 7 is connected to an air cannon, which can clean the processed solid waste materials in time to prevent the solid waste materials from agglomerating.

[0026] The first pneumatic gate valve 11 and the second pneumatic gate valve 12 are respectively connected to the machine-side control box 10 , and the switch of the first pneumatic gate valve 11 and the second pneumatic gate valve 12 is controlled by the machine-side control box 10 .

[0028] The working principle of the utility model is:

[0029] The solid waste is placed on the kiln tail platform through the lifting device. The staff adds the solid waste into the upper feed box 1, then closes the sealing door 4, and then controls the first pneumatic gate valve 11 to be opened through the machine side control box 10, and the solid waste falls into the middle feed box 3. The first pneumatic gate valve 11 is closed and the second pneumatic gate valve 12 is opened through the machine side control box 10, and the solid waste enters the treatment device 9 through the feeding chute 5 and the feed straight pipe 6 for treatment. When the solid waste is treated, the treated material is cleaned and blown through the air cannon connected to the cleaning pipeline 7, waiting for the next treatment of the solid waste.

[0030] The utility model avoids the normal operation of the cement kiln system being affected by the accumulation of materials. When no material is fed into the upper feeder, the first pneumatic gate valve 11, the second pneumatic gate valve 12 and the sealing door 4 of the utility model are all in a closed state, thus effectively preventing the cement kiln system from backflowing, thereby ensuring the stable operation of the cement kiln system and the personal safety of the operators.
