The working principle and the working process of the invention are as follows:
before the reaction kettle 2 is stirred and operated, firstly, materials are added into the kettle body, the materials are directly pumped into the kettle body through a feed inlet 28 by a pump through a feed pipeline, parameters are set in advance by an automatic control system, a filter pressing starting button is pressed to carry out filter pressing treatment, at the moment, a first speed reducing motor 6 is started to control a stirring part to move downwards, a second speed reducing motor 7 starts to rotate forwards, and the materials are stirred and mixed; after the materials are uniformly stirred, nitrogen begins to be introduced into the reaction kettle 2 through the nitrogen port 29, after the nitrogen is added, the second speed reducing motor 7 stops, the first speed reducing motor 6 is started, the stirring part is lifted to the highest position (the distance between the sintering filter screen and the sintering filter screen is about 350mm, a limit switch is arranged at the position), a filter pressing stop button is pressed, and the filter pressing process is ended.
When the material filtering layer in the kettle body is unevenly distributed or is broken, the following operations are required: pressing a filter layer processing start button, pressing a first reducing motor 6 descending button, descending a stirring scraper to the highest point of a filter layer or a filter layer fracture position, switching a forward rotation switch of a second reducing motor 7 to operate, and uniformly flattening the material or eliminating the filter layer fracture by using the scraper; when the materials are evenly spread or the breakage of the filter layer is eliminated, the forward rotation switch of the second speed reducing motor 7 is switched to stop, then the ascending button of the first speed reducing motor 6 is pressed, the stirring scraper is lifted to the highest position, then the filter layer processing stop button is pressed, and the filter layer processing flow is finished.
Next, after the filtration is finished, discharging liquid in the kettle through a liquid outlet 39 at the bottom end, then opening a discharge port 36, pressing a discharge start button, starting the second speed reduction motor 7 to rotate reversely, gradually moving down the first speed reduction motor 6 from the highest position, gradually descending the first speed reduction motor 6 according to a 50mm stroke (keeping a certain time when the first speed reduction motor 6 descends for a certain distance), enabling the first speed reduction motor 6 and the second speed reduction motor 7 to work cooperatively, and enabling the second speed reduction motor 7 to overturn a scraper to push the material out of a side wall discharge port; the first speed reducing motor 6 stops when being reduced to about 10mm above the sintering filter screen 35, the second speed reducing motor 7 continues to rotate reversely until the scraper pushes the materials out of the side wall discharge hole completely, the discharge end button is pressed down, the second speed reducing motor 7 stops rotating reversely, the first speed reducing motor 6 is started to lift the stirring scraper to the highest position, the stirring scraper automatically stops, and the production process is finished.
