After the coordinates are set, the main interface is returned, the parameter interface is entered, whether the parameter values are normal or not is confirmed, the washing times are mainly confirmed, and the main interface is returned after the washing times are accurate. Pressing the "circulation start" button 222 of the button unit 22, the control module 5 receives the operation instructions of the display unit 21 and the button unit 22, and the electric lifting rod performs lifting circulation movement, so that the lifting block 312 in the filtering unit 31 performs lifting circulation movement in the first cavity 321, drives the upper pressing plate 3131 in the pressing block 313, the filter element on the filter element mounting area 3132 and the lower pressing plate 3133 to perform lifting circulation movement, and enables the filter element to perform telescopic circulation movement, and the washing liquid in the second cavity 323 flows into the first cavity 321 through the overflow pipe 3225 to perform multiple elutriation on the filter element by utilizing the negative pressure principle.

After the panning program set by the manual input operation instruction is ended on the display unit 21, the control module 5 controls the stopping of panning. The "circulation stop" key 223 of the key unit 22 may be pressed, so that the control module 5 receives the "circulation stop" operation instruction of the key unit 22, and the electric lifting rod stops lifting, so that the lifting block 312 in the filter unit 31 stops being driven to perform lifting circulation motion in the first cavity 321, and the upper pressing plate 3131 in the pressing block 313, the filter element on the filter element mounting area 3132, and the lower pressing plate 3133 stop being driven to perform lifting circulation motion, and the filter element is stopped being washed.

Then, the valve 3242a outside the bottom cover 324 is opened, and the washing liquid in the second chamber 323 is discharged through the drain pipe 3242 after passing through the filter paper 3243 and the filter paper holder 3241. The second chamber 323 is detached from the lower fixed cover 3222, and after the filter paper 3243 is washed with the washing liquid, the washed washing liquid is collected for subsequent treatment. Meanwhile, the panning information is output through the output module 8, that is, by manually inputting an operation instruction on the touch screen of the display unit 21 of the input module 2, entering a printing interface on the touch screen, confirming printing, and the printer 81 receives the operation instruction information transmitted from the display unit 21 in the input module 2 through the control module 5 and outputs the relevant parameter values of the panning experiment through the printout box 82.

The above procedure was repeated again using panning. After the use, the switch 7 is turned off, the power supply is cut off through the power supply module 6, and the power supply indication lamp 221 on the key unit 22 is turned off.

In conclusion, the automatic two-worm panning machine provided by the invention has the advantages of intelligence, accurate control, high automation degree, printing function, time and labor saving and great popularization and application value. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.
