[0021] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0022] As shown in Figure 1 , 2 A PH value detection device with automatic cleaning PH probe function includes a PH meter, a cylinder system, a support system and a probe automatic cleaning system. The PH value detection device can be used for automatic detection of lime milk reaction tank PH value, but it can be understood that it can also be used for detecting the PH value of other liquids.

[0023] The PH meter includes a probe 101, a PH data transmission line 102, a control and display box 103, and the probe 101 is connected with the control and display box 103 through the PH data transmission line 102. The PH data transmission line 102 transmits the detection data from the probe 101 to the control and display box 103 for controlling, detecting and displaying the PH value. In one embodiment, the control and display box 103 includes a display screen for displaying the PH value.

[0024] The cylinder system includes a cylinder 301, a gas source pipe 302, and a gas source control valve 303, the gas source control valve 303 is connected with the cylinder 301 through the gas source pipe 302, and is used for controlling the up and down movement of the gas rod of the cylinder 301.

[0025] The support system comprises a first support 203, a second support 201, a third support 204 and a fourth support 205. The first support 203 is fixed in space, for example, on a guardrail. The second support 201 is movably installed in the first support 203, so that the second support 201 can move up and down, playing a role in adjusting the position of the cylinder 301, avoiding that the PH detection probe cannot extend into the water due to the over-high or over-low liquid level of the milk of lime reaction tank. The second support 201 and the first support 203 can be fixed by an adjusting bolt 202. The fourth support 205 is fixed on the second support 201, and the cylinder 301 is fixed on the fourth support 205 by a cylinder fixing bolt 304. The third support 204 is installed at the bottom of the cylinder 301 and used for installing the probe 101. The probe 101 is installed on the third support 204, and the third support 204 is immersed in the milk of lime reaction tank. When the air rod of the cylinder 301 moves up and down, the third support 204 at the bottom of the cylinder 301 carrying the probe 101 can be immersed or floated out of the milk of lime tank, facilitating the completion of PH detection and the flushing of the probe 101. In an embodiment, the air rod of the cylinder 301 is connected with the third support 204.

[0026] The probe automatic cleaning system comprises a water storage bucket 401, a water supplementing electric valve 403 installed at a water supplementing opening of the water storage bucket 401, a cleaning electric valve 404 installed at a water outlet opening of the water storage bucket 401, a liquid level meter 402 for detecting the liquid level in the water storage bucket 401, and a pipeline connected to the probe 101 and communicating with the cleaning electric valve 404. The water storage bucket 401 is used for storing water for flushing the probe. The water supplementing electric valve 403 communicates with the water storage bucket 401 and can supplement water into the water storage bucket 401 through the water supplementing electric valve 403. The water supplementing electric valve 403 is connected with an external water source. The liquid level meter 402 is installed in the water storage bucket 401 and can detect the liquid level in the water storage bucket 401. When it is detected that the water storage bucket 401 is full, the water supplementing electric valve 403 is automatically closed. The cleaning electric valve 404 is installed at the water outlet opening of the water storage bucket 401. When the air rod at the bottom of the cylinder 301 performs a lifting action, the cleaning electric valve 404 performs an opening action, and the probe 101 is flushed by the self-flowing water in the bucket. After the flushing is completed, the cleaning electric valve 404 performs a closing action, and thus the flushing of the probe 101 is completed. Then, the air rod of the cylinder 301 can perform a stretching action, so that the probe 101 returns to the milk of lime reaction tank to continue the PH detection.

[0027] In an embodiment, the liquid level meter 402 is used for detecting whether the water level in the water storage bucket 401 reaches an upper limit or a lower limit. When the upper limit is reached, it indicates that the water supplementing should be stopped, and when the lower limit is reached, it indicates that the water supplementing should be started. According to the value fed back by the liquid level meter 402, when the water level reaches the lower limit, the water supplementing electric valve 403 performs an opening action to supplement water, and when the water level reaches the upper limit, the water supplementing electric valve 403 performs a closing action to stop the water supplementing.

[0028] In one embodiment, the height of the water storage bucket 401 is higher than the height of the probe 101. In one embodiment, the water storage bucket 401 can be fixed to the top of the guardrail beside the probe 101, and the probe 101 is washed by the self-flowing water in the water storage bucket 401.

[0029] In one embodiment, the first end and the second end of the air cylinder 301 are fixed on the fourth support 205 by the air cylinder fixing bolt 304. In one embodiment, the fourth support 205 includes an upper arm and a lower arm.
