Problems solved by technology

[0006] The inventor found that the difficulty of the prior art is that the surprise control of the vacuum filtration device relies on the fine control of the vacuum pump, which requires the cooperation of multiple people, which also causes the following specific defects:
[0007] 1. When measuring, two or more people are required to cooperate together, and manual reading is required; the reading accuracy is low
[0008] 2. Since the measuring device currently used is generally a graduated cylinder, t

Abstract

The invention discloses a suction filtration experiment device and method, and belongs to the technical field of buildings. A capillary tube is used, and ripple fluctuation can be prevented from being generated in the process of gathering liquid drops into a measuring cylinder, so that the measurement accuracy is enhanced. The device comprises a bottle body, a funnel, a pressurizing container, a negative pressure source, a measuring pipeline and a server, wherein the bottle body is internally provided with a cavity, and an opening is formed in the top of the bottle body and detachably connected with a bottle plug; a top opening of the funnel is paved with filter paper, and a bottom opening penetrates through the bottle plug and enters the bottle body; the pressurizing container detachably covers the top end of the funnel and can seal the top end of the funnel, the pressurizing container is provided with a plurality of pressurized gas inlets, and each pressurized gas inlet is communicated with a pressure source; the negative pressure source is communicated with the bottle body; a main body of the measuring pipeline is spiral, the measuring pipeline is arranged in the bottle body, an inlet of the measuring pipeline is located under the funnel, and the measuring pipeline is further provided with a water level measuring device for measuring the water level; and the water level measuring device can communicate with the server.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a suction filtration experiment device and method. Background technique [0002] Municipal sludge is a gelatinous waste produced in the process of sewage treatment in municipal sewage treatment plants. Random discharge and stacking of untreated sludge will cause serious environmental problems. International sludge disposal methods mainly include land use, sanitary landfill, incineration, sea throwing, etc. Among them, landfill disposal has relatively loose requirements on technical indicators and low operating costs, and is the main method of sludge disposal at this stage. The simple separate landfill means that after the sludge is dehydrated and digested, it is directly dumped into the pre-set landfill pit to form a temporary sludge storage area. [0003] The inventors found that the sludge has a high water content and poor physical and mechanical properties, w...
