Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of cylinder mixing machine water adding device with clean water flushing pipeline, belong to metallurgical industry sintering machine technical field. BACKGROUND

[0002] Sintering mixture moisture control is the key link of sintering production process, and the stability of mixture moisture control is the key to the stability of sintering process control. The smaller the range of mixture moisture fluctuation, the stronger the stability of sintering production process.

[0003] Currently, the primary condition of sintering production is to meet the A-class enterprise emission standard. After a large amount of flux and other powdery materials in the mixture are wetted with water, a large amount of dust particles with high viscosity and humidity will be generated during the operation of the mixing machine, which is difficult to control. The dust removal effect of the bag-type dust collector is poor, which can easily cause secondary pollution. To prevent dust overflow, a water bath dust removal device is added at the inlet of the mixing machine. To ensure the dust removal effect of the water bath dust removal device, the generated dust removal water needs to be recycled. Using the dust removal water generated by the dust removal device for water addition and balling of the mixing machine not only ensures the dust removal effect of the water bath dust removal device, but also recycles the generated dust removal water. However, using dust removal water can cause blockage of the pipeline of the mixing machine water adding device, resulting in insufficient wetting of the mixed material. The blocked parts are mainly located at the nozzle position. After the nozzle outlet is blocked by particles, the flow rate decreases, and then the mud slowly accumulates, eventually causing the nozzle to be completely blocked, affecting the water addition effect of the mixed material. The nozzle needs to be stopped for dredging, which seriously affects the normal operation of sintering production. SUMMARY

One path is connected to the water outlet of the dust removal water pump through a pipeline. The other path is connected to the water outlet of the clean water pump through a pipeline. The water outlet end of the water adding pipeline is connected to the first blowdown valve.
