be provided with second motor (31), turn over board (32) and portable moisture appearance (33) in detection case (3), wherein turn over board (32) and the output shaft of second motor (31), portable moisture appearance (33) set up at detection case (3) inner wall, be located the upside of turning over board (32).
8. A sludge transfer apparatus as claimed in claim 1 wherein:
the transport mechanism (2) can be provided with a bracket (4).
9. The sludge conveying device and the conveying method thereof are characterized in that the conveying method comprises the following steps:
s1, measuring the water content, wherein in an initial state, an inward turning plate (32) of a detection box (3) is transversely arranged to block a channel leading to a mud storage box (1), an inner pipeline (222) encloses a cylindrical pipeline, and a gate assembly (11) is in a gate closing state; a certain amount of sludge is input above the detection box (3), and when the portable moisture meter (33) above the turning plate (32) is contacted, the portable moisture meter (33) can roughly measure the water content of the sludge and feed back information to the control module;
s2, pipe diameter judgment, namely judging and classifying an interval where the water content of the sludge to be conveyed is located according to the received water content information of the sludge, wherein the sludge with high water content is mainly divided into two major categories, namely a small pipe diameter channel corresponding to the sludge with high water content due to strong circulation property, and a large pipe diameter channel corresponding to the sludge with low water content due to high viscosity, so that the conveying efficiency can be further improved by purposefully selecting the pipe diameter according to the water content, and meanwhile, effective data can be provided for the next procedure for subsequent treatment due to the fact that the water content of the sludge is measured in advance;
s3, high-water-content sludge treatment, wherein when the control module judges that the sludge to be conveyed is in a high-water-content zone, the inner pipeline (222) and the gate assembly (11) maintain an initial state unchanged, the control module drives the second motor (31) to drive the turning plate (32) to turn over 90 degrees towards the side of the portable moisture meter (33) so as to avoid scraping the portable moisture meter (33), and after a passage is formed, the sludge enters the lower sludge storage box (1) and is conveyed out by the conveying mechanism (2);
s4, low-water-content sludge treatment, when the control module judges that the sludge to be conveyed is in a low-water-content zone, the control module drives the gate assembly (11) to lift to expose a rear large-pipe-diameter channel, meanwhile, the drive assembly (224) is controlled, the drive assembly (2244) drives the pulleys to move to the terminal from the initial end to the terminal end through the drive (2242) in the drive assembly, so that the inner pipeline (222) is attached to the outer pipeline (221) to form a large-pipe-diameter channel, and the second motor (31) is driven to drive the turning plate (32) to turn towards the side of the portable moisture meter (33) by 90 degrees at the moment so as to transport the sludge.
