So set up, can send into the box through gas sediment water pan feeding mouth through gaseous cinder and sewage that gas such as gas will contain through external drilling equipment, the gaseous gas that gets into in the box can be discharged through the gas discharging mouth that sets up on the first inner chamber to guarantee safe gas and discharge. Slag and water then fall through gravity, flow into the second inner chamber from first inner chamber through the clearance of baffle and bottom half, and the slag water that flows into in the second inner chamber then can be through the effect of slag water pump, is put into other equipment of further separation cinder and water through slag water discharge pipeline and external pipeline.

According to one scheme of the invention, an inclined baffle plate with adjustable inclination is lapped on the side wall of the first inner cavity facing the partition plate and the bottom wall of the first inner cavity. So set up, can be so that the sediment water that falls down can flow into the second inner chamber through this slope baffle fast to realize quick flow direction sediment water pump, realize being taken out fast and carry out the process of sediment water separation on next step. The inclination of the inclined baffle can be adjusted to adapt to coal cinder with different particle sizes and different water contents, for example, when the particle size of the coal cinder filled in the material is smaller (namely softer and more finely divided coal cinder) and the water content is smaller, the water-containing coal cinder is easy to adhere to the inclined baffle, the inclination of the inclined baffle is properly adjusted to ensure that the whole inclined baffle is arranged more steeply, and at the moment, slag water can more easily enter the second inner cavity through the inclined baffle so as to be discharged by the slag water pump.
According to one scheme of the invention, the inclined baffle plate consists of two baffle plates which are rotatably connected, and one ends of the two baffle plates, which are far away from each other, are respectively in lap joint and sliding connection with the side wall and the bottom wall of the first inner cavity. So set up, can be so that the slope baffle is buckled from the intermediate position, can change the whole radian of slope baffle, be "sunken" form (actually be the bending type form that the baffle of two different slopes formed) in the middle of the adjustment slope baffle for example, can be when gas slag water drops into first inner chamber like this, make gas because inertia along with the in-process that the slag water descends, gas can have more time and stroke and break away from sediment and water, thereby when guaranteeing that the slag water can get into the second inner chamber fast, guarantee that gas can be fully discharged. Of course, the gas discharge port may be connected to a gas suction device, so that the gas in the first cavity can be discharged from the first cavity to other places more quickly and sufficiently by negative pressure suction. Therefore, after the gas is discharged, the residual slag water can be discharged through the slag water pump in the second inner cavity safely, and the problem of potential safety hazard of places is solved.

Because if the liquid level is too high, firstly, the gas separation efficiency can be influenced after the gas slag water feeding port is not passed, and secondly, the gas discharging port is too close to enable the coal slag water to be fed into the special gas drainage pipeline due to negative pressure. The liquid level can of course also be judged by weight. The advantage is that whole case weighing detector does not receive water, sediment influence.
