Abstract

The invention discloses a system for measuring the expansion degree of filter material. The system for measuring the expansion degree of filter material is provided with: a grit settling pan; the lower end of the grit settling plate with a filter screen is equipped with an orifice plate, and the upper end is equipped with a gland; at least A grit chamber is connected in series through fixing bolts to form a probe; the probe is fixed at one end of a hollow plastic conduit; one end of the wire protrudes symmetrically from the side wall of the grit chamber, the other end runs through the plastic conduit, and the other end of the plastic conduit protrudes to connect with the ohmmeter. connect. The invention is simple in structure, easy to carry and assemble, and the length of the conduit and the wire can be adjusted according to the depth of the filter tank (filter column) to be tested. The device for measuring the degree of swelling of the filter material can also be used in environmental protection, petroleum, chemical and other industries under appropriate conditions to measure the interface of liquid and sludge.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a system for measuring the expansion degree of filter material. Background technique [0002] When the filter tank (filter column) in the waterworks and sewage treatment plant is backwashed with water, it is necessary to measure the expansion degree of the filter sand. The previous method is: adopt a steel pipe, weld some small spoons for riding sand on different positions of its lower end, and determine the degree of expansion of the filter material by the sand content in the sand spoons. The tools of this method are complicated to make and cannot be adjusted according to the measured target. The expansion degree is only judged according to the sand content in the small spoon, which is greatly affected by factors such as the volume of the small spoon, the flow velocity in the filter column, and operating errors, and there is a time lag that cannot be...
