Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
Basic scheme of the present invention is: a kind of cell size proving installation, comprise that one for holding the container of slurry, this container has the slurry inlet of top, is arranged at intervals with up and down upper and lower conducting strip in container intracavity, is all connected with for connecting the terminals of wire on upper and lower conducting strip.
Further, the inner chamber of container is up big and down small stepped cavity.
Further, container all form up and down split-type structural, be convenient to the assembling of electrode and fixing.
Concrete, test macro as shown in Figure 1, comprise proving installation and and precision direct current resistance tester 12, tester 12 is by the upper and lower conducting strip 21,20 of wire 11 connecting test devices.
Proving installation main body is a container, and for the ease of production and processing, container adopts cylindrical shape.The inner chamber of container is up big and down small stepped cavity, corresponding with stepped cavity, and container body comprises the upper end cylindrical shell 5 and lower end cylindrical shell 6 being wholely set, and cylindrical shell 5 diameters in upper end are greater than lower end cylindrical shell 6 diameters, and the opening of upper end cylindrical shell 5 is slurry inlet.
Container body upper end is provided with a removable cylindrical shell 1, and upper end cylindrical shell 5 is fixedly connected with removable cylindrical shell 1, is provided with the support for fixing upper conducting strip 21 in upper end cylindrical shell 5 inwalls, and upper conducting strip 21 is fixed on to middle position.As Fig. 1, support 2 be a kind of symmetrically arranged "
" shape shoestring, can support on conducting strip 21.After upper end cylindrical shell 5 and the fixing assembling of removable cylindrical shell 1, upper conducting strip 21 is in stepped cavity upper surface more than 30, to guarantee that upper conducting strip 21 can not stop that slurry flows into the cavity of below.The terminals of upper conducting strip 21 arrange upward, are convenient to the introducing of wire.On upper end cylindrical shell 5 outer walls along being provided with fixed pin jack 4, for removable cylindrical shell 1 time along the corresponding assembling of upper pin.
