Description

Technical Field

[0001] This utility model relates to the field of pH meters, specifically to an online pH meter mounting structure. Background Technology

[0002] Online pH meters have been widely used in many fields. In the current technology, the installation method of online pH meters mainly adopts the pipe insertion structure, that is, the pH meter device is directly installed inside the pipe. This structure has the following drawbacks:

[0003] 1. The pH meter probe is directly exposed to high-speed flowing liquid. Some of the liquid contains solid particles. The continuous friction of the solid particles leads to increased mechanical wear of the probe and shortens its service life. In addition, long-term contact with the liquid can also easily cause scale to form on the probe surface, resulting in sluggish pH meter response or even failure.

[0004] 2. If the pH meter is damaged and needs to be replaced or repaired, the liquid delivery must be stopped before disassembly, which will affect the production schedule.

[0005] 3. It cannot be cleaned online. Conventional backwashing requires the introduction of an external water source, which poses a risk of contamination for liquids that are prohibited from being washed or diluted. It can only be cleaned after disassembly.

[0006] The aforementioned problems have led to a sharp increase in the maintenance costs of online pH meters, which has had an adverse impact on production. Utility Model Content

[0007] The purpose of this invention is to reduce the frequency of maintenance for online pH meters and extend their service life.

[0008] To achieve the above objectives, this utility model provides an online pH meter installation structure, which includes a pH detection chamber. The pH detection chamber is connected to a liquid delivery pipeline via an outlet pipe and to the outside via a liquid discharge pipe. The pH detection chamber is used to detect the pH value of the flowing liquid.

[0009] This invention allows the liquid to be tested to be introduced into the pH testing chamber through the lead-out pipe only when testing is required. The pH value is then measured in the pH testing chamber, and finally the liquid is discharged through the liquid discharge pipe. This prevents mechanical wear and scaling of the pH meter probe caused by long-term impact of the liquid flowing in the pipeline, reduces the number of maintenance times for the online pH meter, and extends its service life.

[0010] Furthermore, the pH testing chamber includes a chamber body and an online pH meter. The outer wall of the chamber body is provided with a mounting base, the pH meter is mounted on the mounting base, and the probe of the online pH meter extends into the interior of the chamber body.

[0011] The housing stores the introduced liquid, allowing it to contact the probe of the online pH meter for detection. The online pH meter is fixed to the housing via a mounting bracket, and its display panel is located on the outside of the housing for easy reading.

[0012] Furthermore, the mounting base is detachably connected to the housing.

[0013] The detachable connection design allows for quick removal of the online pH meter from the enclosure when maintenance or replacement is needed, without damaging the enclosure. Furthermore, by changing the mounting bracket specifications, the mounting structure can be adapted to various pH meter models, expanding its application range.

[0014] Furthermore, the top of the housing is provided with an openable and closable vent.

[0015] The vent is opened when injecting and discharging liquid into the chamber, which facilitates smoother injection and discharge, improving testing efficiency. The vent is closed during normal operation to prevent contamination of the pH testing chamber.

[0016] Furthermore, the housing is equipped with a level gauge for detecting the liquid level.

[0017] Among them, the liquid level in the tank is monitored in real time by a level gauge to ensure that the liquid does not exceed the probe of the online pH meter during testing, thus preventing testing failure.

[0018] Furthermore, the enclosure is made of corrosion-resistant material.

[0019] Corrosion-resistant materials can prevent corrosive liquids from damaging the tank and extend its service life.

[0020] Furthermore, a backwash pipe is installed inside the box, with the outlet of the backwash pipe facing the probe and the inlet of the backwash pipe connected to an external water source.

[0021] The backflushing pipe is used to backflush the probe, achieving effective cleaning without disassembling the online pH meter. Furthermore, because the backflushing pipe is located inside the housing, the backflushing water does not come into contact with the liquid in the pipe, preventing contamination.

[0022] Furthermore, a backwash valve is installed on the backwash water pipe to control the backwashing process.

[0023] Furthermore, the liquid discharge pipe is located at the bottom of the tank, and the outlet pipe is equipped with an outlet pipe valve and a liquid discharge valve.

[0024] The liquid discharge pipe is located at the bottom of the tank for easy discharge of backwash water or liquid. If the online pH meter requires maintenance, the outlet valve can be closed for easy disassembly without stopping the machine and without affecting production progress.

[0025] Furthermore, a filter screen is installed at the connection between the outlet pipe and the liquid conveying pipe to prevent solid particles in the liquid from entering the pH detection box and causing damage.

[0026] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0027] 1. This invention allows the liquid to be tested to be introduced into the pH testing chamber via the lead-out pipe only when testing is required. The pH value is then measured within the chamber, and finally, the liquid is discharged through the liquid discharge pipe. This prevents mechanical wear and scaling of the pH meter probe caused by long-term impact from the flowing liquid in the pipeline, reducing the frequency of online pH meter maintenance, extending its service life, and improving the accuracy and stability of pH value measurement. If maintenance of the online pH meter is needed, the lead-out pipe valve can be closed for easy disassembly without stopping the machine and without affecting production progress.

[0028] 2. This utility model has a backwash pipe installed inside the box to clean the probe. The backwash water will not come into direct contact with the liquid in the pipe, thus avoiding the risk of contaminating the liquid in the pipe. Attached Figure Description
