Problems solved by technology
The production method is intermittent production, the operation time is long, and the labor intensity is high. The discharge suction filter cylinder is open, and a large amount of acidic and harmful gas is discharged during discharge, which is easy to cause environmental pollution. The safety of the entire operation process is poor. Vacuum filtration The device is greatly affected by vacuum and temperature, which may easily cause poor separation and rinsing effects
In addition, the horizontal water flushing vacuum unit is an equipment designated by the state to be eliminated, which does not meet the relevant national safety and environmental protection requirements. Moreover, the operation process has shortcomings such as high labor intensity and poor operation safety. It is no longer suitable for the requirements of modern industrial production. Improve and innovate processes and equipment

The invention provides a device for separating, rinsing and discharging a 2-ethylanthraquinone acidolysis crude product. The device comprises an acidolysis reaction kettle 1, a hydraulic feeding valve2, an automatic centrifugal machine 3, a PLC controller 4, a hydraulic station 5, a rinsing hot water pump 6 and a discharging vehicle 7. By setting a special program, the device is controlled to automatically operate so that the acidolysis crude product is separated, rinsed, discharged and the like, and working efficiency is greatly improved. The device is high in automation degree, a sealing device and a corrosion-resistant material are adopted, and the device has characteristics of a simple structure, convenient operation, good process safety and the like.
Description
technical field [0001] The invention relates to the technical field of automatic operation, and mainly refers to an automatic operation device for separation, rinsing and unloading of 2-ethylanthraquinone acid hydrolysis crude product. Background technique [0002] The original process adopts the separation method of gap vacuum suction filtration. It is necessary to put the crude dilute acid solution that has completed the acidolysis reaction in the acidolysis kettle into the suction filter tank lined with filter cloth, and then pump it through the vacuum filter device composed of water flushing vacuum pump. Filtration, the liquid-phase dilute acid is pumped into the suction filter tank, and the solid crude product in the suction filter tank is washed with hot water to wash away the acidic substances bound in the crude product, and then filtered to dryness through a vacuum filter device, and the rinse wastewater Pumped into the suction filter tank, the rough product after ri...
