[0033] The water and additive batching system 13 comprises a first float ball liquid level meter, a second float ball liquid level meter, a first additive temporary storage tank, a second additive temporary storage tank, a first pneumatic ball valve, a second pneumatic ball valve, a third pneumatic ball valve, a fourth pneumatic ball valve, a first metering hopper, a second metering hopper, a first pull type sensor, a second pull type sensor, a third pull type sensor, a counterweight, a support, a liquid collecting tank, a first additive stirring tank, a second additive stirring tank, a first additive pump and a second additive pump.

[0034] According to production needs, the prepared raw materials are unloaded into the additive stirring tank by manual or pump, the additive stirring tank is provided with a back flushing pipeline, a plurality of gas outlets are arranged at the bottom of the additive stirring tank, an air compressor is connected to the gas circuit, and an electric control stop valve is arranged on the pipeline; after being stirred in the additive stirring tank, the additive is pumped into the additive tank through the first additive pump, the second additive pump and the liquid feeding pipeline, and then is sent into the first metering hopper and the second metering hopper through the first pneumatic ball valve and the second pneumatic ball valve for weighing; when the float ball liquid level meter fails, the additive can be returned to the additive stirring tank through the liquid return pipeline; the two kinds of weighed additives enter the liquid collecting tank, and are mixed with the weighed water in the liquid collecting tank, and then enter the stirring machine together.

[0037] The dust removal system in the utility model is related to the following information: the dust removal system comprises a dust collection pipeline, a dust remover, a spiral machine, a cement injector, a dust conveying pipeline, a check valve, a support platform, a fly ash tank, an outer package and a gas inlet pipeline.

[0038] When the stirring system is in the continuous working state, the dust removal system starts to work synchronously to collect the dust generated by the double-machine stirring module, and the collected dust enters the conical hopper of the dust collector through the pipeline. A manual butterfly valve is installed in the dust collection pipeline to adjust the air volume in the pipeline. The selection of the dust collector is determined by the required treatment air volume of the dust collection place. After the dust collector starts to work, the electric control stop valve opens and releases compressed air to send ash. The conical body of the dust collector is equipped with a screw machine to realize intermittent feeding. When the electric control stop valve is open, the gas passes through the cement injector to blow the residual ash in the injector and the pipeline into the tank. When the screw machine starts to work, the cement injector is in a continuous ash feeding state. After the screw machine works for a certain period of time, it stops working. After a certain delay, it works again. The working state of the screw machine is a small cycle with a fixed time. The cycle works intermittently.

The aggregate batching device 2 measures the sand and stone by a pressure sensor or a suspension sensor. The sand and stone is first discharged to about 80% of the weighing value. This proportion can be adjusted according to actual needs. If the amount is insufficient, the lower arc door feeder of the aggregate bin 1 is operated to ensure accurate measurement. If the amount is excessive, the excess sand and stone can be deducted when unloading. The remaining material is used for the next batch of measurement. The sand and stone material after weighing is unloaded into the horizontal rubber belt conveyor 3. In order to prevent the sand and stone material from rolling on the feeding rubber belt conveyor 4, the sand and stone after weighing is first unloaded by half, then the stone is unloaded, and finally the remaining sand is unloaded.

The service life of the feeding rubber belt conveyor 4 is prolonged, and the operation is more reliable. In addition, the rubber belt conveyor roller is designed in a 35° deep "V" shape, which increases the conveying capacity and transportation reliability of the rubber belt conveyor.
