Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings. Only this statement, the utility model discloses the upper and lower, left and right, preceding, back, inside and outside etc. position words that appear or will appear in the text only use the utility model discloses an attached drawing is the benchmark, and it is not right the utility model discloses a concrete restriction.
As shown in fig. 1, the embodiment of the present invention provides a PH value sampling and detecting device, which includes an electric three-way valve 1, a detecting pipe section 2, a mixing tank 3, a liquid outlet pipe section 4 and a liquid supply pipe section 5; one end of the liquid outlet pipe section 4 is connected with an inlet 13 of the electric three-way valve 1, one end of the liquid supply pipe section 5 is connected with a first outlet 11 of the electric three-way valve 1, and one end of the detection pipe section 2 is connected with a second outlet 12 of the electric three-way valve 1; a PH detection device 6 is arranged on the detection pipe section 2, the upper part of the mixing tank 3 is connected with the other end of the detection pipe section 2, and the bottom part of the mixing tank is connected with the other end of the liquid outlet pipe section 4; the mixing tank 3 is also connected with a neutralizing acid tank (not shown in the figure) through a neutralizing pipe section 7; a centrifugal pump 8 is arranged on the liquid outlet pipe section 4; the liquid supply pipe section 5 is used for supplying liquid dye liquid for the dye vat.
Preferably, a drain pipe 41 is further connected to the liquid outlet pipe section 4. The detection pipe section 2 comprises a vertical liquid supply pipe 21, a transverse detection pipe 22 and a vertical liquid return pipe 23; the PH detection device 6 is arranged on the transverse detection pipe 22, and the height of the transverse detection pipe 22 is higher than that of the connecting position of the vertical liquid return pipe 23 and the mixing tank 3. By adopting the structure, after no new dye liquor is introduced into the detection pipe section 2, the dye liquor in the detection pipe section 2 automatically and slowly flows into the mixing tank 3 under the action of gravity, so that the influence on the detection result caused by the stop of the dye liquor at the PH detection device 6 is avoided.
The electric three-way valve 1 can switch the device between a dye liquor acidity adjusting state and a dye liquor output state, and when the device is in the dye liquor acidity adjusting state, an inlet 13 of the electric three-way valve 1 is communicated with a second outlet 12; when in the dye liquor output state, the inlet 13 of the electric three-way valve 1 is communicated with the first outlet 11.

In order to realize intelligent control of the pH value of the dye liquor, the centrifugal pump 8 is connected with a frequency converter (not shown in the figure), and the frequency converter can control the rotating speed of the centrifugal pump 8 according to the detection data of the pH detection device 6. When the PH value obtained by the PH detection device 6 deviates from the preset value too much, the frequency converter accelerates the rotating speed of the centrifugal pump 8 and accelerates the circulation of the dye liquor in the mixing tank 3, so that the dye liquor is contacted with more neutralizing liquor; when the PH value obtained by the PH detection device 6 is close to the preset value, the frequency converter slows down the rotating speed of the centrifugal pump 8 and the circulation of the dye liquor in the mixing tank 3, so that the PH value of the dye liquor is stabilized within a certain range.
The working principle of the device is as follows: the PH detection device 6 detects the PH value of the dye liquor flowing through, when the deviation value is greater than a preset value, the electric three-way valve 1 is in a dye liquor acidity regulation state, and an inlet 13 of the electric three-way valve 1 is communicated with a second outlet 12; the centrifugal pump 8 feeds the liquid in the mixing tank 3 into the top of the mixing tank 3 again through the detection pipe section 2, and the impact force flowing in through the centrifugal pump is mixed with the acid solution introduced from the neutralization acid tank in the mixing tank 3.
The PH detection device 6 continuously detects the PH value of the dye liquor flowing through, and when the deviation value is smaller than a preset value and the dye liquor is in a dye liquor output state, an inlet 13 of the electric three-way valve 1 is communicated with a first outlet 11; the dye liquor in the mixing tank 3 is conveyed to the subsequent process flow through a liquor outlet pipe section 4. When the dye liquor in the mixing tank 3 is less than the preset value, new dye liquor is added into the mixing tank 3 again.
By adopting the scheme, the automatic detection and control of the pH value of the dye liquor can be realized, the detection is accurate, and the labor is saved.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and decorations can be made without departing from the principle of the invention, and these modifications and decorations are also regarded as the protection scope of the present invention.
