Description

Technical Field

[0001] The utility model relates to the technical field of pH meter cleaning, and more specifically to a device for automatically lifting and cleaning a pH meter at intervals. Background Art

[0002] As a commonly used measurement and control instrument, pH meter is mainly used to accurately measure the pH value of various liquid media. Due to its wide applicability, it is often used in industry, agriculture, environmental protection and other fields. Especially in industry, it is widely used. For example, in the treatment of arsenic-containing wastewater in copper smelting by the lime-iron salt method, the measurement and control of the pH value of the treated liquid is the key basis for whether the arsenic removal can meet the standard. The treated liquid contains substances such as Ca(OH)2 and CaSO4, which are easy to adhere to the glass electrode of the pH meter during the pH value measurement and control process, causing the glass electrode to be unable to continuously and accurately reflect the pH value of the treated liquid, affecting the operation of subsequent processes. At the same time, the continuous flushing of the treated liquid can easily cause damage to the glass electrode.

[0003] Therefore, it is an urgent problem for those skilled in the art to develop a device that can clean and protect the pH meter and automatically lift and clean the pH meter at intervals. Utility Model Content

[0004] In view of this, the utility model provides a device for automatically lifting and cleaning the pH meter at intervals, which can clean the pH meter and protect the pH meter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for automatically lifting and cleaning a pH meter at intervals, comprising:

[0009] A flushing liquid pipeline, wherein a flushing liquid valve is provided on the flushing liquid pipeline;

[0010] A crank-connecting rod mechanism, one end of which is hinged to one end of the lifting rod connected to the pH meter, and the other end is fixedly connected to the switch wrench of the flushing liquid valve, and the swing of the crank-connecting rod mechanism will open or close the flushing liquid valve.

[0011] The beneficial effect of adopting the above technical solution is that in the utility model, the pH meter is removed from the detection tank by moving the lifting rod upward, and at the same time the lifting rod can drive the crank-connecting rod mechanism to operate, open the flushing liquid valve, and then flush the pH meter. The pH meter can be flushed regularly to ensure the accuracy of pH value detection.

[0012] Preferably, an anti-scour sleeve is fixed in the detection tank, the pH meter extends into the anti-scour sleeve, and a liquid inlet hole is provided on the surface of the anti-scour sleeve. The anti-scour sleeve can slow down the flow rate of the measured medium, thereby protecting the pH meter and preventing the measured medium from flowing too fast to damage the pH meter.

[0013] Preferably, a pneumatic lifting mechanism is provided on the top of the lifting rod, and the pneumatic lifting mechanism is connected to an air supply pipe. The lifting rod can be driven to rise by supplying air into the pneumatic lifting mechanism, thereby achieving flushing of the pH meter.

[0014] Preferably, the air supply pipe is provided with an air supply valve, which can control the start and stop of the lifting movement of the lifting rod.

[0015] Preferably, a soft jacket is connected to the bottom of the lifting rod, and the soft jacket clamps the top of the pH meter. The soft jacket is made of flexible material, which can not only clamp the pH meter, but also avoid damage to the pH meter during clamping.

[0016] Preferably, the crank-connecting rod mechanism comprises: a long lever and a short lever; one end of the long lever is hinged to the soft jacket, and the other end is hinged to the short lever; one end of the short lever away from the long lever is fixedly connected to the switch wrench of the flushing liquid valve. The long lever moves with the lifting rod and drives the short lever to rotate, thereby driving the switch wrench of the flushing liquid valve to rotate, thereby opening or closing the flushing liquid valve.

[0017] Preferably, the liquid outlet of the flushing liquid pipeline is connected to a spray head, which can disperse the flushing liquid flowing out of the flushing liquid pipeline to more comprehensively and effectively flush the pH meter.

[0018] Preferably, the pH meter is connected to a signal line for transmitting the detection signal outward.

[0019] It can be seen from the above technical solution that, compared with the prior art, the utility model discloses a device for automatically lifting and cleaning a pH meter at intervals, and its beneficial effects are:

[0020] (1) In the utility model, the lifting rod and the pH meter are lifted by the pneumatic lifting mechanism, and the flushing liquid valve is started to flush the pH meter, thereby ensuring that the pH meter can stably and accurately monitor the pH of the medium and transmit data, thereby avoiding data distortion;

[0021] (2) The anti-scouring sleeve can slow down the flow rate of the measuring medium, prevent the pH meter from being scoured and worn by the medium, protect the pH meter, and greatly extend the service life of the pH meter. BRIEF DESCRIPTION OF THE DRAWINGS

Under the action of the crank connecting rod mechanism 6, when the pH meter 2 is lifted, the flushing liquid valve 5 is opened at the same time, which makes the operation easier, and the pH meter 2 can be flushed to ensure the accuracy of the detection result of the pH meter 2.

[0035] In order to further optimize the above technical solution, an anti-scour sleeve 7 is fixed in the detection tank 1, and the pH meter 2 extends into the anti-scour sleeve 7. A liquid inlet hole is provided on the surface of the anti-scour sleeve 7. The liquid inlet hole allows the measured medium to enter the anti-scour sleeve 7, so that the pH meter 2 can detect the pH value of the measured medium. At the same time, the liquid inlet hole of the anti-scour sleeve 7 can slow down the flow rate of the measured medium when entering, and avoid scouring and wear of the pH meter 2.

[0036] In order to further optimize the above technical solution, a pneumatic lifting mechanism 8 is provided on the top of the lifting rod 3 , and the pneumatic lifting mechanism 8 is connected to an air supply pipe 9 .

[0037] In order to further optimize the above technical solution, an air supply valve 10 is provided on the air supply pipe 9. The air supply valve 10 is a timed air supply valve, which is opened for 5 minutes every 25 minutes. When the air supply valve 10 is opened, the pH meter 2 is flushed.

[0038] In order to further optimize the above technical solution, a soft jacket 11 is connected to the bottom of the lifting rod 3 , and the soft jacket 11 clamps the top of the pH meter 2 .

[0039] In order to further optimize the above technical solution, a glass electrode is provided at the bottom of the pH meter 2, and the glass electrode is rinsed during rinsing to ensure the accuracy of the test result. At the same time, the anti-scouring sleeve 7 can prevent scouring and wear of the glass electrode.

[0040] In order to further optimize the above technical solution, the crank-connecting rod mechanism 6 includes: a long lever 61 and a short lever 62; one end of the long lever 61 is hinged to the soft jacket 11, and the other end is hinged to the short lever 62; one end of the short lever 62 away from the long lever 61 is fixedly connected to the switch wrench of the flushing liquid valve 5.

[0043] Working principle:

[0044] When cleaning the pH meter 2, the air supply valve 10 is opened, and the compressed air enters the pneumatic lifting mechanism 8 through the air supply pipe 9. The lifting rod 3 lifts the pH meter 2 to the top of the measured medium. During the lifting process, the long lever 61 is driven to move through the soft jacket 11, and the long lever 61 drives the right end of the short lever 62 to move upward. The right end of the short lever 62 moves upward, and the flushing liquid valve 5 is opened. The flushing liquid passes through the flushing liquid pipeline 4 and is dispersed by the spray head 12 to flush the glass electrode at the lower end of the pH meter 2. The flushing liquid flows downstream with the measured medium and will not interfere with the monitoring results. When the pH of the measured medium is monitored, the air supply valve 10 is closed, the pneumatic lifting mechanism 8 is in a non-working state, and the pH meter 2 falls into the anti-scouring sleeve 7 in the detection tank 1 to monitor the pH of the treated liquid. The monitoring signal is transmitted to the display instrument through the signal line 13. During the descent process, the long lever 61 and the short lever 62 are driven downward by the soft jacket 11, and the flushing liquid valve 5 is closed accordingly. The air supply valve 10 is opened for 5 minutes at intervals of 25 minutes, thereby repeatedly performing flushing and testing operations.
