[0002] The sintering machine gas solid waste treatment device is mainly used for treating gaseous and solid waste generated in the steel sintering process, and has key significance for realizing green and sustainable development of the steel industry. In the steel production process, the sintering process will produce a large amount of dust-containing waste gas, harmful gas and various solid waste. If these wastes are not properly treated, not only will they cause serious pollution to the environment, but also will lead to waste of resources. In actual application scenarios, whether it is a large steel joint enterprise or a relatively small sintering production plant, efficient gas and solid waste treatment devices are needed to meet the needs of environmental protection and resource utilization. The current sintering machine gas solid waste treatment device usually needs the following technologies in actual application:

[0032] Gap sleeve 11: as the bearing frame of the whole screening and partial driving structure, it provides installation space and support for internal components such as crank rod 12, driving motor 17, screening bucket 15, etc.

[0033] Crank rod 12: one end is connected with driving motor 17, and the other end is rotationally connected with rectangular connecting rod 13; it does circular motion under the driving of driving motor 17, and through its rotation, it periodically pulls rectangular connecting rod 13, converting the rotary motion of the motor into the reciprocating linear motion of rectangular connecting rod 13, which is a key link for power transmission to drive the subsequent shaking of screening bucket 15;

It is a key equipment for the preliminary separation of gas and solid, laying a foundation for the further treatment of waste gas and solid waste.

[0045] Gas collector 25: It is used to adsorb and collect waste gas and solid waste generated during the production of the sintering machine, and guide them to the cyclone dust collector 24 for treatment, ensuring that the waste generated during the production process can be effectively collected and preventing unorganized discharge.

[0046] Spray cooling tower 26: Through the internal spray pipe, it cools the waste gas, reduces the temperature of the waste gas, and makes it reach the temperature range that the subsequent treatment equipment can withstand, ensuring the normal operation of the subsequent equipment. It is an important part of the waste gas treatment process.

[0047] Working principle:

[0048] The first step, the gas collecting hood 25 provided in the cyclone dust collector 24 is used to adsorb and collect the waste gas, solid waste and other waste generated during the production of the sintering machine. The gas collecting hood 25 adsorbs the waste gas, solid waste and other waste into the cyclone dust collector 24. The waste gas is preliminarily separated from the large particles of dust in the waste gas by using the principle of centrifugal force in the cyclone dust collector 24. At this time, the gas floats upwards, and the dust and solid waste are discharged along the lower end discharge pipe of the cyclone dust collector 24 to the jaw crusher 23. The waste gas is discharged along the upper end pipe of the cyclone dust collector 24 into the spray cooling tower 26. The waste gas is cooled and treated by the spray pipe provided in the spray cooling tower 26, the temperature of the waste gas is reduced, and finally the waste gas is discharged to reach the temperature range that can be tolerated by the subsequent treatment equipment. The solid waste is crushed by the jaw crusher 23 to reduce the particle size of the solid waste, such as sintered ore undersize, steel slag and other solid waste. The crushed waste is discharged into the screening barrel 15 along the inclined discharge plate provided in the jaw crusher 23. The waste is classified and screened by the two spherical screen plates 22 provided in the screening barrel 15. The large waste is blocked on the upper spherical screen plate 22, the medium size waste is blocked on the lower spherical screen plate 22, and the small size waste falls into the inner wall of the screening barrel 15. The inner wall of the screening barrel 15 and the upper surface of the two spherical screen plates 22 are spherical. The waste falls along the inclined surface of the sphere and finally is discharged through the three inclined discharge plates 21 provided in the screening barrel 15 for subsequent use. The above process completes the integrated and collaborative treatment of solid waste, which is compact in structure and effectively reduces the emission of gaseous and solid waste.

[0049] The second step, when the material is discharged into the screening barrel 15, the drive motor 17 installed in the notch sleeve 11 is started to drive the crank rod 12 connected thereto to make circular motion. With the rotation of the crank rod 12, it periodically pulls the rectangular connecting rod 13 to make reciprocating displacement. Under the reciprocating pulling action of the rectangular connecting rod 13, the impact lifting block 14 slides up and down. When the impact lifting block 14 moves upward, it contacts and lifts the hollow circular ring base 16. In this way, the hollow circular ring base 16 drives the screening barrel 15 to make reciprocating lifting action, so that the screening barrel 15 is shaken, effectively accelerating the screening process of the waste. During the shaking and screening of the screening barrel 15, the movement of the barrel body causes the four springs 19 installed below it to be continuously compressed. The spring 19 rebounds after being compressed. The continuous compression and rebound process produces a resonance effect, further improving the shaking frequency of the screening barrel 15 and significantly improving the screening efficiency.

[0050] Finally, it should be noted that: apparently, the above embodiments are merely examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made. Here, it is not necessary and impossible to exhaust all the implementation. The obvious changes or variations derived from it are still within the protection scope of the utility model.
