4. The waste liquid coal water slurry incineration boiler according to claim 1, characterized in that: the conveyor (10) is preferably a screw conveyor.

5. The method for using the waste liquid coal water slurry incineration boiler according to claim 1, characterized in that: the method comprises the following steps: when the device is used, waste liquid is added into a waste liquid pool, a floating ball floats upwards to drive a first deflector rod to rotate, the other end of the first deflector rod is separated from the inclined surface of a valve rod, the first deflector rod is separated from a first switch, a ball plug is plugged into a liquid conveying pipe by the tension of a third spring when the valve rod is not stressed, the liquid conveying pipe is in a blocked state, and a tee joint below a slag melting pool initially flows into a second slag fishing pool; secondly, stirring the waste liquid and the coal powder in a stirrer, spraying the mixture into a boiler through a jet pump for incineration, allowing residual large-particle coal and slag to fall into a slag pool after the incineration, and allowing a large amount of steam generated in the slag pool to enter a steam recovery box through a first steam pipe for recovery; thirdly, the cooled slag flows into a second slag salvaging pool through a tee joint, and the slag is sent into a first storage bin through a slag salvaging machine; fourthly, when the waste liquid in the waste liquid pool is used up, the liquid level is lowered, the floating ball falls into the bottom of the waste liquid pool, the floating ball drives the first shifting lever to rotate, the end part of the first shifting lever pushes the valve rod to the right through the inclined plane of the valve rod, the third spring is compressed, the ball plug is extruded into the cavity on the side of the infusion tube at the moment, and meanwhile, the first boss on the first shifting lever is contacted with the first switch, so that the first switch controls the push rod on the tee joint to move, and the tee joint flows to the first slag fishing pool; and simultaneously, controlling the action of the crusher, the conveyor and the feeding device by the first switch, conveying the crushed slag and the waste coal powder into the incinerator for combustion, and finally flowing the residual slag into the first slag salvaging tank for fishing out after combustion.
