[0014] In S4, the following steps are also included: S42. During the drying process of the moist air, the drying state is monitored by a humidity sensor, and then the electric heating plate is adjusted by a heating controller.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is equipped with a cleaning component. After the monitoring device is used, the cleaning nozzle is driven to rotate by the hollow fan plate, and the cleaning liquid is sprayed to rinse and clean the part of the bottom of the monitoring unit extending into the slurry. The hollow fan plate is rotated synchronously by the arrangement of the worm gear, the worm, the driving gear and the inner ring gear. When the hollow fan plate rotates to the direction of the cleaning nozzle on its inner wall toward the inner wall of the monitoring box, the inside of the monitoring box is rinsed and cleaned, and the position of the hollow fan plate can be adjusted, which is beneficial to improving the cleaning effect of the inside of the monitoring box, avoiding the slurry from adhering to the outer wall of the monitoring unit and the inner wall of the monitoring box, affecting the next use of the monitoring device, and is beneficial to improving the concentration monitoring accuracy of the monitoring device.

[0017] 3. The present invention sets a transmission funnel and a humidity sensor to detect the dryness of the gas after the gas passes through a group of electric heating plates for heating and drying. When the dryness of the detected gas reaches a set threshold, the heating control unit turns off the use of the remaining electric heating plates to avoid repeated heating and drying of the gas that has reached the dryness threshold, which is beneficial to saving energy and improving the energy-saving effect of the monitoring equipment.

[0018] 4. The present invention blocks the drying path between the electric heating plates that are not needed by installing a through groove, a sealing plate and a sliding plate. The sealing plate moves to restore the through groove to a connected state, so that the gas with a dryness reaching a threshold value is directly transferred downward to the position of the gas output pump inlet through the transfer funnel and the through groove, shortening the gas flow path, which is beneficial to speeding up the drying efficiency inside the monitoring box and improving the utilization efficiency of the concentration monitoring equipment.

The wall is slidably connected, and electromagnet 1 44 and electromagnet 2 45 are respectively installed on the left and right inner walls on both sides of the sealing plate 39, and electromagnet 1 44 and electromagnet 2 45 are respectively located on both sides of the insulating plate 40, and a controller is installed on the inner wall of the sealing plate 39, and the controller is used to control electromagnet 1 44 and electromagnet 2 45 so that the on and off states of electromagnet 1 44 and electromagnet 2 45 are opposite, and a telescopic rod 2 38 is embedded in the interior of the monitoring box 1, and the output end of the telescopic rod 2 38 is connected to the top of the sealing plate 39.

[0034] Furthermore, when taking slurry into the monitoring box 1 through the slurry inlet 37, the right electromagnet 2 45 is in the on state, and the left electromagnet 1 44 is in the off state. The electromagnet 2 pulls the insulating plate 40 to the right through the magnetic attraction, and then drives the cross bar 42 to pull the leveling plate 43 to move to the right, so that the right outer wall of the leveling plate 43 fits the outer wall of the sealing plate 39, and the telescopic rod 2 38 is shortened, pulling the sealing plate 39 and the leveling plate 43 upward to the monitoring box 1, so that the slurry inlet 37 leaks out, so that the slurry enters the monitoring box through the slurry inlet 37.

[0035] Working principle: The monitoring box 1 is installed on the outer wall of the rake rod inside the thickener, and the slurry is collected through the slurry inlet 37 to enter the monitoring box 1, and the slurry inlet 37 is sealed with a sealing plate 39. The slurry concentration in the monitoring box 1 is detected by the monitoring unit 3 using a multi-parameter fusion sensor. After the detection is completed, the slurry is discharged through the one-way discharge valve at the bottom of the monitoring box 1. The dual-axis motor 13 drives the worm 14 and the vertical rod 15 to rotate, and the worm gear 12 drives the hanging ring 7 to rotate, so that the hollow fan plate 8 rotates outward, and the pump body transmits the cleaning liquid in the liquid storage tank 10 to the hollow fan plate 8 through the infusion pipe 11, and then through the cleaning The nozzle 9 sprays cleaning liquid outward to rinse and clean the monitoring unit 3 and the inner wall of the monitoring box 1. After the rinsing is completed, the gas capture pump 20 and the gas output pump 21 are started to extract the moist gas on the inner wall of the monitoring box 1 into the drying box 19 for drying, and the dried gas is discharged back into the monitoring box 1. The slurry concentration is monitored by setting a concentration monitoring device installed inside the thickener, instead of taking the slurry out for testing, which improves the monitoring efficiency. The cleaning and drying of the monitoring components are carried out in the thickener to avoid taking out the monitoring equipment, further improving the monitoring efficiency and ease of use.
