[0002] The clean recovery coke oven gas collection system is mainly composed of riser, gas collection pipe and gas collection main pipe. The riser is mainly used to connect the rising fire channel of the carbonization chamber wall of the furnace body and the gas collection pipe. The normal working temperature is about 800~900 degrees. The material is mostly clay refractory material. The riser sends the high-temperature exhaust gas completely burned in the coke oven combustion chamber into the gas collection pipe, making full and effective use of high-temperature waste heat. The riser lining brick is the main lining brick in the coke oven riser, generally composed of 6 pieces of clay material with a porosity of about 20%;

By setting the L-shaped block 9 and the spring 12, when the raw material contacts the crushing part, the crushing part can be shaken, and then the raw material can fall down.

[0031] The crushing part includes a clamping rod 20 mounted between two frame rods 21, the outer surface of the clamping rod 20 has slopes 33 on both sides, and a plurality of crushing cone heads 19 are vertically mounted on the outer surface of the clamping rod 20;

[0032] Reference Manual Attached Figure 3 and Figure 6 It can be seen that the crushing cone head 19 can disperse the agglomerates and reduce the agglomerations in the raw materials, so as to ensure the full utilization of the raw materials. The outer surface of the clamping rod 20 is set in a slope 33, which can reduce the hanging of the raw materials on the wall, and enable the raw materials to fall to the bottom through the gap between adjacent clamping rods 20 after contacting the crushing cone head 19.

[0036] Reference Manual Attached Figure 5 It can be seen that under the transmission cooperation of the transmission wheel 30 and the synchronous belt 31, the chuck 29 and the chuck shell 32 outside the chuck shaft 35 are driven by the transmission structure to centrifugally disperse the raw materials falling from the material passage, so that the raw materials can achieve preliminary mixing.

[0037] Two fixed rods 28 are fixedly installed on one side of the bottom of the arc-shaped bucket 13, and a connecting shaft 27 is inserted and rotated together inside the two fixed rods 28.

A second motor 24 is fixedly installed on the outside of one of the fixed rods 28, and the output shaft of the second motor 24 is fixedly connected to the connecting shaft 27;

[0038] Reference Manual Attached Figure 4 and Figure 5It can be seen that the two fixing rods 28 are used to mount the connecting shaft 27 . When the second motor 24 drives the connecting shaft 27 to rotate, the external first bevel gear 25 will mesh with the second bevel gear 26 , thereby causing the clamping shaft 35 to rotate.

[0039] The conveying mechanism includes a conveying pipe 8, which is arranged below the lower material bin 4 and the upper surface of which is connected to the interior of the lower material bin 4 through a connecting port. A first motor 7 is arranged at one end of the outer side of the conveying pipe 8, one end of the first motor 7 extends into the interior of the conveying pipe 8 and the end is connected to a rotating shaft 17, a spiral blade 14 is installed on the outer side of the rotating shaft 17, and a connecting assembly is arranged at the lower part of the interior of the conveying pipe 8 to communicate with the feed pipe 6;

For specific reference, please refer to the ball mill model specification of Ф1200×3000.

[0043] Working principle: When in use, various raw materials are poured into the processing box 3. During the falling process, the raw materials contact the crushing cone 19 on the outer surface of the clamping rod 20, so that the crushing cone 19 disperses the agglomerates in the raw materials, and then fall into the arc bucket 13 through the gap between the two adjacent clamping rods 20. The heating plates 10 on both sides of the arc bucket 13 can dry and heat the materials inside the arc bucket 13 during the processing process, thereby reducing moisture in the raw materials and reducing the adhesion of the raw materials to the steel balls inside the ball mill body 1. The raw materials contact the chuck 29 at the lower end through the material inlet, and the second motor 24 drives the connecting shaft 27 to rotate on one side of the arc bucket 13, so that the connecting shaft 27 The first bevel gear 25 on the outside is rotatably engaged with the second bevel gear 26, and the second bevel gear 26 drives the clamping shaft 35 and the external chuck 29 to rotate. During the rotation process, the upper part of the outside of the clamping shaft 35 is driven by the synchronous belt 31 and the transmission wheel 30, and the two clamping shafts 35 rotate at the same time. During the rotation process, the raw materials falling into the inside of the clamping shell 32 can be initially mixed under the action of centrifugal force, and the dispersed raw materials fall into the inside of the conveying pipe 8. The first motor 7 drives the rotating shaft 17 and the spiral blade 14 inside the conveying pipe 8 to rotate, and the raw materials inside the conveying pipe 8 are automatically transmitted to the discharge pipe 18. Finally, through the guide pipe 16 and the rotating sleeve 15, the raw materials are sent into the inside of the ball milling device body 1 for fine mixing.
