Abstract
Description
Technical Field
[0001] The utility model belongs to the field of liquid mixing equipment, and in particular relates to a mixing barrel for acid concentration. Background Art
[0002] Steel wire produced by drawing needs to be pickled before electroplating to remove surface oil stains. Our company usually dilutes the purchased concentrated acid to prepare the pickling solution. Before the invention, the pickling solution was prepared directly in an open tank through manual operation. Due to the strong corrosiveness of the acid solution, this preparation method often poses a safety hazard. Utility Model Content

[0004] One end of the water adding pipeline is connected to the upper side of the barrel body, the other end of the water adding pipeline is connected to an external water source, and a water adding control valve is provided on the water adding pipeline; one end of the acid adding pipeline is connected to the upper side of the barrel body, the other end of the acid adding pipeline is connected to an external acid source, and an acid adding control valve is provided on the acid adding pipeline; one end of the liquid outlet pipeline is connected to the bottom surface of the barrel body, the other end of the liquid outlet pipeline is connected to an external liquid storage tank or acid-using equipment, and a liquid outlet control valve is provided on the liquid outlet pipeline; a liquid level gauge is connected to the side of the barrel body for observing the liquid level in the barrel body and the amount of concentrated acid and water added;
[0005] One end of the bypass line is connected to the front of the valve of the acid addition line through a three-way pipe fitting, and the other end of the bypass line is connected to the rear of the valve of the liquid outlet line through a three-way pipe fitting. A bypass valve is provided on the bypass line. When the concentration of the recovered acid source does not need to be adjusted by adding water, the bypass valve can be opened to bypass the barrel body through the bypass line; one end of the overflow line is vertically arranged above the inside of the barrel body, and the other end of the overflow line is located outside the barrel body and is connected to the rear of the valve of the bypass line through a three-way pipe fitting. When the liquid level in the barrel body is too high, it can be discharged from the overflow line in time to ensure safety.
[0006] Preferably, the water addition control valve, acid addition control valve and liquid outlet control valve are all pneumatic diaphragm valves, which can be remotely controlled to open and close the valves through an air source, making the preparation of the acid solution more convenient.
[0007] Preferably, a support plate is provided below the water addition control valve and the acid addition control valve, and the valve bodies of the water addition control valve and the acid addition control valve are fixedly connected to the support plate respectively. The support plate is fixedly connected to the side of the barrel body through a fixed plate. The pneumatic diaphragm valve is large in size and heavy in weight. In this way, the support of the support plate can prevent the water addition pipeline and the acid addition pipeline from being deformed due to the weight of the valve.
[0008] Preferably, an exhaust pipeline is provided on the cover plate of the barrel body to balance the air pressure in the barrel body, so that concentrated acid and water can be added smoothly and the prepared acid solution can be discharged smoothly.
[0009] Furthermore, a sampling line is connected to the valve front of the liquid outlet pipeline through a three-way pipe fitting, and a sampling valve is provided on the sampling line. The liquid in the barrel can be sampled through the sampling line and the sampling valve to detect the concentration. A floor drain is provided below the open end of the sampling line, and the floor drain is connected to the external waste liquid recovery tank through a pipeline. The floor drain can collect the acid dripping during sampling to prevent the acid from dripping outside and forming a safety hazard.
[0010] Through the above technical solution, the utility model has at least the following beneficial effects:
[0011] The acid concentration mixing barrel described in the present application is easy to use. Acid and water addition operations can be performed through the cooperation of preset pipelines and the barrel body. During the entire concentration mixing process, the acid is in a relatively closed space. Workers can complete the concentration mixing without contacting the acid, which is highly safe.
