Since the detecting block 410 is fixedly connected with the blocking rod 440, the blocking rod 440 is used for preventing the scraper 210 from sliding towards the side wall of the filter vat 110. When the detection block 410 slides along the third section 433, the blocking rod 440 slides towards the axial direction of the centrifugal cylinder 120, so that the thickness of the sludge treated by the scraper 210 is increased, at the moment, the telescopic hydraulic rod contracts, oil in the telescopic hydraulic rod enters the oil cavity of the hydraulic cavity 390, the air cavity of the hydraulic cavity 390 is extruded, and the telescopic hydraulic rod tends to extend.
After the sludge in the centrifuge tube 120 is dewatered, the sludge is taken out from the side wall of the centrifuge tube 120, at this time, the weight of the centrifuge tube 120 is reduced, the centrifuge tube 120 is made to slide upwards along the driving shaft 320 under the action of the return spring 520, the detection block 410 is made to slide towards the side wall close to the centrifuge tube 120 under the action of the first spring 450, and the telescopic hydraulic rod is made to extend gradually under the action of the air cavity of the hydraulic cavity 390, so that the scraper 210 is abutted against the stop lever 440 fixedly connected with the detection block 410, and the device is made to gradually return to the initial state.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
