AI Technical Summary
In the production of electrolytic copper foil, the sampling port of copper sulfate solution is prone to dead loops, which can lead to pipeline blockage. Furthermore, the droplets after sampling can cause crystallization on the ground. The existing valve control method is not ideal.
Design a sampling port device including an inlet pipe, a guide pipe, and an outlet pipe. The guide pipe has a larger diameter than the inlet and outlet pipes, has a sampling notch, and is equipped with a dust cover and a sampling window. The dust cover is constructed using PVC board and plexiglass board to ensure convenient sampling and prevent crystallization.
It effectively prevents pipe blockage and ground crystallization, and improves the convenience and safety of sampling operations.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrolytic copper foil production technology, specifically to a copper sulfate solution sampling port device. Background Technology
[0002] The copper sulfate solution used in the production of electrolytic copper foil needs to be sampled and tested. Currently, the sampling port is controlled by a valve. After sampling is completed and the valve is closed, a dead loop occurs before and after the valve, which easily causes crystallization and leads to frequent blockages in the pipeline. On the other hand, after sampling, the residual electrolyte in the pipeline drips onto the ground, causing crystallization and slipperiness.
[0003] Therefore, in order to correct the above-mentioned defects, we propose a copper sulfate solution sampling port device. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a copper sulfate solution sampling port device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper sulfate solution sampling port device, comprising an inlet pipe, a guide pipe, and an outlet pipe, wherein the inlet pipe is connected to the inlet end of the guide pipe, and the outlet pipe is connected to the outlet end of the guide pipe, wherein the diameter of the guide pipe is larger than the diameter of the inlet pipe and the outlet pipe, and a sampling notch is provided on the guide pipe.
[0006] Furthermore, the diameter of the inlet port on the liquid guide tube connected to the liquid inlet tube is smaller than the diameter of the liquid inlet tube.
[0007] Furthermore, the inlet and outlet ends of the liquid guide tube are symmetrically arranged.
[0008] Furthermore, it also includes a dust cover, with the liquid guide tube inside the dust cover, and a liquid dispensing window installed on the dust cover, which is connected to the dust cover via a hinge.
[0009] Furthermore, the dust cover is composed of several PVC boards.
[0010] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a DN150 CPVC pipe at the copper sulfate sampling port, with a DN25 CPVC pipe leading out from each end as the inlet and outlet pipes for the sampling port. The inlet, which was originally DN150, is now reduced to DN15 to ensure concentrated liquid intake. The dust cover is welded from PVC board, and the sampling window is made of plexiglass, serving both observation and dust prevention purposes. This solves the crystallization problem and makes sampling more convenient and faster. Attached Figure Description

[0014] 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.
[0015] This utility model provides a technical solution:
[0016] Please see Figure 1 A copper sulfate solution sampling device includes an inlet pipe 2, a guide pipe 5, and an outlet pipe 8. The inlet pipe 2 is connected to the inlet end of the guide pipe 5, and the outlet pipe 8 is connected to the outlet end of the guide pipe 5. The diameter of the guide pipe 5 is larger than the diameter of the inlet pipe 2 and the outlet pipe 8. The inlet pipe 2 is connected to an inlet valve 1. A sampling notch is provided on the guide pipe 5, so that the copper sulfate solution entering the guide pipe 5 is exposed from the sampling notch, and the worker can directly sample from the sampling notch.
[0017] In addition, a dust cover 4 is added. The top and bottom of the dust cover 4 are connected and supported to the inlet pipe 2 and the outlet pipe 8, respectively. The liquid guide pipe 5 is located inside the dust cover 4. A liquid retrieval window 7 is installed on the dust cover 4. The liquid retrieval window 7 is connected to the dust cover 4 through a hinge 6. A door latch 10 is also installed on the liquid retrieval window 7 to lock the liquid retrieval window 7. When retrieving liquid, the liquid retrieval window 7 on the dust cover 4 is opened first, and then the liquid is retrieved.
[0018] Specifically, a DN150 CPVC pipe is taken from the copper sulfate sampling port, and a DN25 CPVC pipe is led out from each end of the pipe to serve as the inlet and outlet pipes for the sampling port. The inlet of the DN150 pipe is reduced to DN15 to ensure concentrated liquid intake. The dust cover is welded with PVC board, and the sampling window is made of plexiglass, which serves both observation and dust prevention purposes. This solves the crystallization problem and makes sampling more convenient and faster.
