Description

Technical Field

[0001] This utility model relates to the field of wastewater reuse technology, and more specifically to a pH value detection device for wastewater reuse. Background Technology

[0002] With the development of industrial production and the prosperity of the social economy, human activities generate a large amount of wastewater. If this wastewater is not treated in a timely manner, it will seriously pollute the human living environment. Among the various indicators in wastewater treatment, pH is a frequently tested and controlled item. Therefore, pH testing devices are installed in wastewater reuse equipment for monitoring. Existing pH testing devices typically use pH meters, which are supported by an installation mechanism and inserted into the wastewater for measurement.

[0003] For example, in the prior art disclosure number CN219777653U, there is a sewage pH value detection device for a sewage tank. This utility model uses a slider to push the pH meter probe downward to insert it into the sewage to detect the pH value. After the detection is completed, the rotating motor reverses to drive the pH meter probe back into the cylinder. When not detecting, the pH meter probe is away from the sewage, which can effectively reduce the rate of corrosion of the pH meter probe.

[0004] However, the existing technology has the following problems when used: due to the long-term standing of sewage, the concentration of pH value inside the sewage will be unevenly distributed. Traditional detection devices can only detect the pH value of sewage at one place at a time, and the height needs to be frequently adjusted to detect the pH value of sewage at different depths, resulting in low detection efficiency. Based on this, the present invention provides a pH detection device for sewage recycling with high detection efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a pH value detection device for wastewater reuse. By using the detection heads of multiple pH detectors on the detection column to detect wastewater at different depths, the pH value of wastewater at different depths can be detected simultaneously, thereby greatly improving detection efficiency. Furthermore, the use of a protective cover can protect the detection heads of multiple pH detectors from accidental collisions and damage, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pH detection device for wastewater reuse, comprising a detection column, wherein at least one pH meter is installed inside the detection column, and the pH meter is provided with a detection end, the detection end penetrating through the outer wall of the detection column for detecting the pH value in the wastewater, a protective cover is connected to one side of the detection column, and the other side of the detection column has the same number of mounting slots as the pH meter, the protective cover is fitted over the detection ends of the multiple pH meters, the protective cover is connected to the detection column through a rotating assembly, and a fixing assembly is connected to the detection column for supporting the detection column to be inserted into the wastewater for detection.

[0007] In a preferred embodiment, each pH meter is fixedly provided with a sealing plate on the side away from the protective cover. The sealing plate is detachably connected to the mounting groove. After long-term use, the operator can remove the sealing plate from the mounting groove to inspect and replace the pH meter.

[0008] In a preferred embodiment, a sealing strip is provided between the protective cover and the outer wall surface of the detection column to improve the sealing performance between the two. The sealing strip can further improve the sealing performance between the protective cover and the detection column when the protective cover is closed.

[0009] In a preferred embodiment, the rotating assembly includes a rotating rod fixed to one side of the protective cover. A servo motor for driving the rotating rod to rotate is connected to the top of the rotating rod. The servo motor is detachably mounted on the detection column. The servo motor drives the rotating rod to rotate the protective cover, thereby realizing the automatic opening and closing of the protective cover.

[0010] In a preferred embodiment, the fixing component includes a fixing column, the top of which is rotatably connected to a fixing member, and a connecting column is detachably connected within the fixing member, which can be used to support the detection column.

[0011] In a preferred embodiment, a connector is fixedly provided at one end of the connecting column near the detection column. The detection column is rotatably connected inside the connector. A second servo motor is fixedly provided at the rear end of the connector. One end of the output shaft of the second servo motor passes through the connector and is fixed to the detection column. The second servo motor drives the detection column to rotate, thereby adjusting the angle of the detection column.

[0012] In a preferred embodiment, the number of pH detectors is set to multiple, and the multiple pH detectors are distributed at equal intervals from top to bottom on the detection column, thereby improving the detection efficiency of wastewater pH value.

[0013] The technical effects and advantages of this utility model are as follows:

In addition, the protective cover can protect the detection ends of multiple pH detectors from accidental collisions and damage.

[0015] 2. The detection column is supported by a fixed and connecting column, and the angle of the detection column is automatically adjusted by a servo motor, making it faster to use and allowing the detection column to perform detection at different angles. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figure 1-5This utility model provides a pH value detection device for wastewater recycling, including a detection column 1. At least one pH meter 2 is installed inside the detection column 1. The pH meter 2 is an important tool for measuring and reacting the acidity and alkalinity of a solution. A DARK pH3110 can be selected, which can perform pH / ORP measurement, high and low limit alarm control, current output and digital communication, etc. The temperature can be automatically or manually compensated. The pH meter 2 is provided with a detection end 201, which penetrates through the outer wall of the detection column 1 and is used to detect the pH value in the wastewater. A protective cover 3 is connected to one side of the detection column 1. A sealing strip 8 is provided between the protective cover 3 and the outer wall surface of the detection column 1 to improve the sealing between the two. The other side of the detection column 1 has the same number of mounting slots 4 as the pH meter 2. The protective cover 3 is fitted over the detection ends 201 of the multiple pH meters 2.

[0026] The number of pH detectors 2 is set to multiple, and the multiple pH detectors 2 are distributed at equal intervals from top to bottom on the detection column 1, so as to improve the detection efficiency of the pH value of wastewater.

[0027] The protective cover 3 is connected to the detection column 1 via a rotating assembly 5. Specifically, the rotating assembly 5 includes a rotating rod 501, which is fixed on one side of the protective cover 3. A servo motor 502 for driving the rotating rod 501 to rotate is connected to the top of the rotating rod 501. The servo motor 502 is detachably mounted on the detection column 1.

[0028] The detection column 1 is connected to a fixing component 6 for supporting the detection column 1 when inserted into the sewage for detection. Specifically, the fixing component 6 includes a fixing column 601, a fixing member 602 rotatably connected to the top of the fixing column 601, a connecting column 603 detachably connected inside the fixing member 602, a connecting member 604 fixedly provided at one end of the connecting column 603 near the detection column 1, the detection column 1 being rotatably connected inside the connecting member 604, and a servo motor 605 fixedly provided at the rear end of the connecting member 604, one end of the output shaft of the servo motor 605 passing through the connecting member 604 and fixed to the detection column 1.

[0029] In practical use, the fixing column 601 is first installed next to the wastewater recycling treatment equipment. Then, the servo motor 2 605 drives the detection column 1 to rotate and insert it into the wastewater. The servo motor 1 502 then drives the rotating rod 501 to open the protective cover 3, allowing the detection ends 201 of multiple pH meters 2 to detect wastewater at different depths. This allows for the simultaneous detection of pH values ​​at different depths, improving detection efficiency. When it is no longer necessary to detect the pH value of the wastewater, the servo motor 2 605 can be used to drive the detection column 1 to rotate and remove it from the wastewater, and the protective cover can be opened. The wastewater adhering to the detection ends 201 of the pH meters 2 and the wastewater on the protective cover 3 will drip into the wastewater under gravity. Alternatively, the detection ends 201 can be rinsed with a spray gun as needed.

[0030] In this embodiment, servo motor 502 and servo motor 605 can be selected from the Lihao servo motor LH180 series, with a power of 3.0kw-15kw. It is an auxiliary motor indirect speed change device that can accurately control parameters such as speed, position and torque, and can convert the input electrical signal into angular displacement or angular velocity output on the shaft. Therefore, with the help of servo motor 502 and servo motor 605, there is sufficient power to drive the rotating rod 501 and the detection column 1 to rotate.

[0031] Refer to the instruction manual appendix Figure 1-5 Each pH meter 2 is fixedly equipped with a sealing plate 7 on the side away from the protective cover 3. The sealing plate 7 is detachably connected to the mounting groove 4. After long-term use, the staff can remove the sealing plate 7 from the mounting groove 4 to inspect and replace the pH meter 2.
