Problems solved by technology

Its shortcomings are: ①This device only realizes the integration of a set of suction and filtration units, which is only suitable for independent experiments of one person and one sample, which is not conducive to the simultaneous experiment of multiple groups of students, or the simultaneous experiment of multiple groups of parallel samples
②The opening of the curved tube at the lower end of the Buchner funnel is open downward. When the sludge dewatering performance is good and the filtrate is pumped out too quickly, it is very easy to splash water and affect the fluctuation of the liquid level, and the ideal anti-drip effect cannot be obtained.
③In the whole device, the main components such as Buchner funnel, suction filter cartridge and vacuum pump are scattered on the workbench, without forming a movable integrated device, and there are still problems such as inconvenient disassembly and transportation

Description

technical field [0001] The invention relates to a measuring device, in particular to a multi-connected sludge specific resistance measuring device for measuring sludge dewatering specific resistance parameters. Background technique [0002] Specific resistance is a main parameter reflecting the dewatering performance of sludge. Its physical meaning is: when a unit weight of sludge is filtered under a certain pressure, the resistance on the unit filter area is the resistance of the unit dry weight of the filter cake on the unit filter area. have resistance. The influencing factors of specific resistance measurement include: experimental pressure, solid content rate and other parameters, etc. In this experiment, the main parameter is to determine the slope of t / V~V linear regression. Therefore, accurate determination of each parameter and reduction of experimental errors have a significant impact on the accuracy of experimental results. [0003] At present, the specific resi...
