[0026] It should be noted that: chemical raw materials are poured into the kettle body 1 through the feeding trough 3, and then water is injected into the cavity of the kettle body 1 from the water injection hole 4, and then the knob 65 above the frame 63 is turned to drive the screw 64 to rotate.

At this time, the arc-shaped groove 16 will squeeze the arc-shaped block 17. The arc-shaped block 17 will be squeezed and move in the filter box 13 and squeeze the spring 18. At this time, the slider 19 slides in the slide groove, so that the arc-shaped block 17 can be separated from the arc-shaped groove 16, and then the filter screen plate 14 can be taken out of the filter box 13. The filter screen plate 14 can be installed in the filter box 13 by reverse operation.

[0036] The working principle of a temperature-controlled steam-heated chemical reactor provided by the utility model is as follows:
