Embodiment Construction

[0024] The present invention will be further elaborated below in conjunction with accompanying drawing and specific embodiment;

[0025] Such as figure 2 As shown, when the sludge scraper in the sedimentation tank performs the mud scraping operation, the sludge in the sedimentation tank is not only pushed toward the center of the circle by the force of the scraper 11, but also moves the bottom mud to the center of the pool along the slope of the bottom of the pool inclined toward the center by gravity. The scraper 11 is welded on the scraper arm 10 and is inclined at a certain angle to the axis of the scraper arm 10, so that the normal line of the tangent to the outer diameter of the arc of the scraper 11 has a centripetal thrust 26 facing the center of the pool, and the centripetal thrust 26 It is enough to scrape the sediment to the mud collecting chamber 17 in the center of the sedimentation tank, and then use the mud pump 19 to pump out the bottom mud of the mud collectin...

Abstract

A method and device for pumping high-concentration bottom mud with a fixed torque of a mud scraper in a sedimentation tank, to read the value of the scraping reaction force of the mud scraper, and divide the mud pumping procedure into several steps based on this value , so that the concentration of sludge extracted by the sludge scraper reaches the highest and stable, which is conducive to the dehydration of the subsequent dehydration facilities in the sedimentation tank, and ensures that the sludge scraper's operating torque can be kept within a safe range with the highest proper rate.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a method and a device for pumping high-concentration bottom mud with a fixed torque for a mud scraper in a sedimentation tank. Background technique [0002] The suspended particles contained in the wastewater generated during the production process of the factory need to undergo a sedimentation separation process before being discharged to remove the suspended particles from the wastewater so that the wastewater becomes a clear liquid before being discharged. Performing this function in the wastewater treatment program is a coagulation sedimentation program, and it is implemented in the coagulation tank and the sedimentation tank. [0003] Such as figure 1 As shown, in the existing coagulation and sedimentation operation, the raw water 1 and the coagulation liquid 2 are injected into the coagulation tank 3 with the help of the mixer 4 in the tank to forcibly...
