Embodiment
See also shown in Figure 1ly, be first embodiment of the present utility model, wherein, discharge device 1 is for having the container of a height (H), the bottom sealing, and top is an openend 7, and discharge device 1 bottom is provided with a pressure detector 3, and feed tube 4 is directly all to discharge device 1; Drain pump 2 also is a container, and it is communicated with a discharging tube 5, and the open end portion 7 on discharge device 1 top is nested in the drain pump 2, and the two is combined into into an integral body; The remainder of the discharge device 1 that combines with drain pump 2 does not expose, and each side is equipped with support bar 6.
By shown in Figure 2, the pressure detector 3 that is provided with at discharge device 1 has a sensitive area, is used to detect the concentration of cement grout, and this sensitive area directly touches the cement grout in the discharge device 1; The openend 7 on the top of discharge device 1 is the discharge face of liquid, and the height of drain pump 2 will be higher than this openend discharge face 7.After the liquid in discharge device 1 container was all filled, liquid can overflow by openend 7, flowed in the drain pump 2, and got rid of by discharging tube 5.
The course of work of the utility model cement grout concentration device for dynamically detecting is as follows:
Just can dynamically detect force value on the pressure detector at any time by said process.Just can draw the concentration of real-time cement grout, i.e. proportion size again by converting.
Draw the concentration of cement grout by following formula:
P0 is the pressure at zero point of pressure detector,
P1 is the force value that clear water passes through this equipment,
P2 is the force value that cement grout passes through this equipment,
R1 is the proportion of clear water,
R2 is the proportion of cement grout,
H is the height of discharge device,
Draw according to hydraulic ultimate principle:
P1＝P0+R1×H(1)
P2＝P0+R2×H(2)
(2) formula is deducted (1) formula to be got:
P2-P1＝(R2-R1)×H(3)
Because the proportion R1 of water is generally 1, so with R1=1 substitution (3) formula, the proportion R2 that just can draw cement grout through conversion is:
R2＝(P2-P1)/H]+1
