Description
Technical field
The invention belongs to the electrochemical measuring technique field, relate to a kind of installation and pick-up unit that adopts glass electrode to carry out continuous detecting, be specifically related to a kind of stationary flow measuring pool that is used for electro-chemistry sensing glass electrode.
Background technology
In a large amount of fields such as metallurgy, chemical industry, electric power, medicine, all need chemical reaction related in its production run, cooling liquid or the like, carry out the detection of chemical property, such as the detection of pH, sodion or the like all kinds of electrochemical parameters.Traditional detection method is to gather fluid to be measured with glass container, and electrode is inserted in the liquid in the glass container, and the detected signal of glass electrode is transferred to secondary instrument again, shows the data of detection signal.But this method can only be used for detection occasion off-line, discrete.And needs are carried out the occasion of continuous detecting, generally exactly electrode is directly inserted chemical reaction container or detected pipeline at present.
Yet the maximum characteristics that electro-chemistry glass electrode detects require electrode to be in the detected relatively stably liquid exactly.One requires detected liquid phase to steadily, no big motion; Its two, require detected liquid directly not impact electrode surface.Obviously, at present electrode is directly inserted the method for container or pipeline, must cause the inaccurate or serious fluctuation of testing result.
Summary of the invention
Purpose of the present invention is exactly at the deficiencies in the prior art, for electro-chemistry glass electrode provide one stably, shock-free, the stationary flow measuring pool that can realize continuous detecting arranged.
The present invention includes the measuring cell body of drum type, the sidewall of measuring cell body is provided with water inlet near bottom position.The measuring cell bodies top is set with end cap, and the center of end cap vertically is provided with glass electrode, and glass electrode one end stretches out measuring cell, and this is external, and an end extend into the inner chamber of measuring cell body.Be provided with the water conservancy diversion outer ring of cylinder type in the measuring cell body, be provided with the current stabilization inner ring of cylinder type in the water conservancy diversion outer ring.The lower end of the lower end of water conservancy diversion outer ring and current stabilization inner ring respectively with bottom fixed seal connection, the upper end of current stabilization inner ring and the end cap fixed seal connection of measuring cell body.The bottom barrel of current stabilization inner ring has many row's water inlet apertures, and the height of topmost one row's aperture is lower than the lower end that is fixed on the glass electrode on the end cap.End cap inside is provided with exhalant canal, the exhalant canal one end opening inner chamber that the current stabilization inner ring surrounds in the measuring cell body, and the other end communicates with the external world.
Advantage of the present invention is: 1) space in the middle of lower bottom base of this device and the outer back-up ring reduces fluid to be measured speed greater than water inlet greatly, makes liquid form stably stratified flow by the annular space between outer ring and the inner ring again; 2) liquid flows into inner ring through the porous of inner ring bottom, avoids the impact of liquid to glass electrode, for glass electrode forms stable measurement environment; 3) this device is connected with pipeline in the production run by water inlet and water delivering orifice, can realize the continuous detecting to fluid to be measured; 3) this apparatus structure is simple, realization is convenient, it is reliable to use.
Apparatus of the present invention, overtesting and obtain a large amount of practical applications, have simple in structure, realize convenient, use series of advantages such as reliable, that testing result is accurate.

Embodiment
As shown in Figure 1, the stationary flow measuring pool of electrochemical sensor glass electrode comprises the measuring cell body of drum type, and the sidewall 4 of measuring cell body is provided with water inlet 9 near bottom positions.The measuring cell bodies top is set with end cap 1, and the center of end cap 1 vertically is provided with glass electrode 2, and glass electrode 2 one ends stretch out measuring cell, and this is external, and an end extend into the inner chamber of measuring cell body.Be provided with the water conservancy diversion outer ring 5 of cylinder type in the measuring cell body, be provided with the current stabilization inner ring 7 of cylinder type in the water conservancy diversion outer ring 5.The lower end of the lower end of water conservancy diversion outer ring 5 and current stabilization inner ring 7 respectively with bottom 6 fixed seal connections, the upper end of current stabilization inner ring 7 and end cap 1 fixed seal connection of measuring cell body.The bottom barrel of current stabilization inner ring 7 has many row's water inlet apertures 8, and wherein the height of topmost one row's aperture 8 is lower than the lower end of the glass electrode 2 that is fixed on the end cap 1.End cap 1 inside is provided with exhalant canal 3, the exhalant canal 3 one end openings inner chamber that current stabilization inner ring 7 surrounds in the measuring cell body, and the other end communicates with the external world.
Detected liquid flows into measuring cell from water inlet, on the sidewall of measuring cell body and the space between the water conservancy diversion outer ring, rise, cross the annular space between inflow water conservancy diversion outer ring, upper end, water conservancy diversion outer ring and the current stabilization inner ring, flow into the inside of current stabilization inner ring again by the water inlet aperture on the current stabilization inner ring lower periphery, contact with the glass electrode that is in current stabilization inner ring center, form the electrochemical parameter detection of glass electrode this liquid.Water inlet aperture position on the current stabilization inner ring lower periphery is lower than the lower end of middle glass electrode, thereby makes fluid to be measured slow in, stable, shock-free electrode tip, and formation is stablized and measured accurately.
