Description

Technical Field

[0001] This utility model relates to the field of pickling water detection technology, and in particular to an online pickling water detection device. Background Technology

[0002] Electric circuit steel pipe poles, iron towers, communication steel pipe poles, high light poles, etc. are all made of steel pipes and poles. After the steel pipe poles are processed and shaped, their surfaces are cleaned and then galvanized and electrostatic sprayed to improve their corrosion resistance.

[0003] Currently, before cleaning the surface of steel pipe poles, pickling water is used to clean the surface of the steel pipe poles to remove oxide scale and rust. In order to ensure the cleaning power of the pickling water, a testing device is used to test the pH value of the pickling water.

[0004] Existing technologies all use pH meters to detect the acidity or alkalinity of pickling water. However, the detection head of existing pH meters is easily corroded and damaged when immersed in pickling water for extended periods. Therefore, we propose an online pickling water detection device. Summary of the Invention

[0005] The main objective of this invention is to provide an online detection device for pickling water, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An online acid washing water detection device includes a pH meter body, a cylinder, and a funnel groove. The cylinder is located on one side of the pH meter body. A slot is formed inside the cylinder, and a detection head is fixedly engaged inside the slot. A funnel groove is formed at the bottom of the slot. A first water inlet groove is formed inside the cylinder on one side of the slot, and a second water inlet groove is formed inside the cylinder on the other side of the slot. A solenoid valve is connected to the end of the second water inlet groove on the outer side of the cylinder via a pipe. A float plate is fixedly fitted at the bottom outer side of the cylinder. A small water pump is mounted on one side of the cylinder via a mounting bracket. A drainage groove is formed at the bottom of the cylinder.

[0008] Furthermore, the signal output terminal of the detection head is electrically connected to the signal input terminal of the pH meter body via a power cord, and the bottom end of the detection head is located inside the funnel groove; this facilitates the detection of the acid wash water drawn into the funnel groove.

[0009] Furthermore, a protective net is connected to the bottom of the float plate via a threaded groove, the inlet end of the small water pump is connected to the inside of the protective net via a pipe, and the outlet end of the small water pump is connected to one end of the first inlet tank via a pipe; the protective net can prevent impurities from being drawn into the first inlet tank.

[0010] Furthermore, the end of the solenoid valve furthest from the cylinder is connected to a flexible hose via a threaded groove.

[0011] Furthermore, the funnel trough and the drainage trough are connected by a connecting groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The small water pump draws pickling water from the first inlet tank into the funnel tank. The detection head can detect the pickling water in the funnel tank and transmit the detection data to the pH meter for processing and display, making it easy for personnel to view. The pickling water entering the funnel tank can slowly flow out from the drain tank through the connecting tank, so that the bottom of the detection head will not be soaked in the pickling water for a long time. Opening the solenoid valve allows external clean water to flow into the funnel tank through the second inlet tank, which can clean the bottom of the detection head located in the funnel tank and prevent it from being corroded by the pickling water.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3As shown, an online acid washing water detection device includes a pH meter body 1, a cylinder 2, and a funnel trough 3. The cylinder 2 is located on one side of the pH meter body 1. A slot 4 is provided inside the cylinder 2, and a detection head 5 is fixedly engaged inside the slot 4. A funnel trough 3 is provided at the bottom of the slot 4. A first water inlet trough 10 is provided inside the cylinder 2 on one side of the slot 4, and a second water inlet trough 11 is provided inside the cylinder 2 on the other side of the slot 4. A solenoid valve 7 is connected to the end of the second water inlet trough 11 on the outside of the cylinder 2 through a pipe. A float plate 9 is fixedly fitted at the bottom of the outside of the cylinder 2. A small water pump 6 is installed on one side of the cylinder 2 through a mounting bracket. A drainage trough 13 is provided at the bottom of the cylinder 2.

[0020] Among them, such as Figure 1 and Figure 2 As shown, the signal output terminal of the detection head 5 is electrically connected to the signal input terminal of the pH meter body 1 via a power cord. The bottom end of the detection head 5 is located inside the funnel groove 3. The data detected by the detection head 5 is transmitted to the pH meter body 1 for processing and display.

[0021] Among them, such as Figure 1 and Figure 2 As shown, the bottom of the float plate 9 is connected to a protective net 14 through a threaded groove. The inlet end of the small water pump 6 is connected to the inside of the protective net 14 through a pipe. The outlet end of the small water pump 6 is connected to one end of the first water inlet tank 10 through a pipe. The small water pump 6 works to pump pickling water into the first water inlet tank 10 through the protective net 14.

[0022] Among them, such as Figure 1 As shown, the end of the solenoid valve 7 away from the cylinder 2 is connected to a flexible hose 8 via a threaded groove. The flexible hose 8 facilitates the connection of the solenoid valve 7 to an external water supply device.

[0023] Among them, such as Figure 2 As shown, a connecting groove 12 is provided through the funnel trough 3 and the drainage trough 13, and the opening of the connecting groove 12 facilitates the flow of pickling water in the funnel trough 3 out of the drainage trough 13.

[0024] It should be noted that this utility model is an online detection device for pickling water. During operation, personnel use bolts to fix the pH meter body 1 to the side of the pickling water tank or pool. The device is connected to an external power source using a power cord, and one end of the hose 8 is connected to an external water supply device. The cylinder 2 is placed on the pickling water, and the float 9 uses its own buoyancy to keep the cylinder 2 afloat on the surface of the pickling water. The small water pump 6 is turned on, pumping the pickling water through the protective net 14 into the first inlet tank 10. The pickling water entering the first inlet tank 10 flows into the funnel trough 3. The pickling water in the funnel trough 3... The washing water flows slowly out of the drain trough 13 through the connecting groove 12, so that the funnel trough 3 always contains acid washing water. The detection head 5 in the slot 4 can detect the acid washing water in the funnel trough 3 and transmit the detection data to the pH meter body 1 for processing and display, so that personnel can easily view it. After the detection is completed, the small water pump 6 is turned off and the solenoid valve 7 is turned on. External clean water flows through the hose 8 and the solenoid valve 7 to the second water inlet trough 11, and then through the second water inlet trough 11 to the funnel trough 3. This can clean the bottom of the detection head 5 located in the funnel trough 3, so that it is not easily corroded by the acid washing water.
