Description

Technical Field

[0001] The utility model relates to a multi-point sampling system for pre-treatment of plated parts, belonging to the technical field of sample detection instruments. Background Art

[0002] Traditional pre-treatment bath liquid testing for plated parts usually adopts a single-point sampling method, which cannot fully reflect the state of the entire bath liquid and easily leads to one-sided test results. In addition, single-point sampling cannot monitor the changes in components at different locations in the bath liquid, which is not conducive to timely detection and handling of local abnormalities. Pre-treatment bath liquid testing mainly relies on manual sampling and laboratory titration, which is inefficient, time-consuming, and susceptible to human errors. Traditional detection methods cannot achieve real-time monitoring. Galvanizing companies rely entirely on experience for production, which puts production under imprecise control, resulting in an increase in the scrap rate of steel pipes, causing huge economic losses and waste of energy and resources to companies.

[0016] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the following further elaborates the utility model in combination with specific embodiments.

[0017] The utility model is a multi-point sampling system for pre-treatment of plating parts, mainly used for sampling the bath solution for pre-treatment of plating parts, and can realize multi-point sampling.

[0018] This system mainly includes a central control unit, a data acquisition unit and a number of sampling units. Among them, the sampling units are distributed at different positions of the bath solution and are used for sampling the bath solution at different positions. The sampling units can sample the bath solution at multiple points simultaneously or separately. The data acquisition unit is used to collect data at the sampling points and send the data to the central control unit. The central control unit is responsible for scheduling the work of each sampling unit and transmitting sampling instructions. The central control unit is communicatively connected to the data acquisition unit and the sampling point unit. The key point of the utility model is multi-point sampling, and a plurality of sampling units are set. The central control unit and the data acquisition unit among them are applications of conventional technologies.

[0019] Such as Figure 1 、 Figure 2 、 Figure 3As shown, in the present utility model, the sampling unit includes a power pump 3, a filter 1, and a waste discharge assembly. The sampling unit samples in the bath solution of the production line. The power pump 3 is the power component of the sampling unit, and the power pump 3 pumps the sample into the filter 1. The filter 1 is used to filter the sample, and then discharges the filtered sample for use by the subsequent unit that detects the sample. The waste discharge assembly is used to externally discharge the waste liquid and the cleaning waste liquid.

[0020] Further, specifically, the inlet of the power pump 3 of the sampling unit is connected to the liquid inlet interface 4, and the outlet of the power pump 3 is connected to the inlet of the filter 1. The outlet of the filter 1 is used by the subsequent unit that detects the sample. The filter 1 is also provided with a cleaning liquid outlet for discharging the cleaning liquid, and the cleaning liquid outlet is connected to the cleaning waste discharge valve 2. The cleaning waste discharge valve 2 is connected to the liquid discharge interface 6. The cleaning waste discharge valve 2 is the waste discharge assembly.

[0021] In a specific implementation, the sampling unit further includes a sampling box body 7, and the sampling unit is distributed and installed in the form of a box body. The liquid inlet interface 4, the liquid discharge interface 6, and the communication interface 5 are arranged on the surface of the sampling box body 7.

[0022] During use, the sampling unit is installed on the production line. In the bath solution of the production line, the bath solution is circulated into the filter 1 through the power pump 3. After the bath solution is filtered, it becomes a clear sample to be detected and waits for detection. The residual impurities and the bath solution in the filter 1 will be washed out by the cleaning module and discharged through the cleaning waste discharge valve 2. The collection unit is controlled by the central control unit, selects different sampling points for sampling, and transports them to the subsequent detection unit. The sample to be detected filtered in the filter 1 enters the detection component through the sampling system and is detected.

[0023] In the pretreatment tank of the hot-dip galvanizing production line, multiple sampling units are arranged according to the size and shape of the bath solution. The central control unit sets the sampling plan, including the sampling point position, sampling frequency, and sampling volume. The data acquisition unit collects the data of each sampling point and transmits it to the central control unit for analysis and processing.

[0024] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
