Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foil processing, in particular to a continuous quantitative adding device for activated carbon. Background Art

[0002] Activated carbon plays an important role in the processing of electrolytic copper foil. Due to its porosity and high specific surface area, activated carbon can effectively adsorb impurities in the electrolyte, including organic matter, metal ions, etc., during the circulation of the electrolyte. This adsorption can not only purify the electrolyte and improve the electrolysis efficiency, but also reduce the color and turbidity in the electrolyte, thereby increasing the service life of the equipment.

[0003] In actual operation, activated carbon is usually prepared with water and added to the diatomaceous earth filter, so that when the electrolyte to be filtered passes through the diatomaceous earth filter, organic matter, arsenic and other impurities in the electrolyte are filtered out, thereby achieving a filtering effect. However, it should be noted that the adsorption capacity of activated carbon is limited, so it is necessary to add activated carbon to the filter regularly. The traditional method of adding activated carbon is manual and regular addition, which has unstable process control and cannot ensure that the amount of activated carbon added is accurate and continuous in time. At the same time, there are also problems such as high labor intensity of employees and difficulty in cleaning due to the strong adhesion of activated carbon, which affects the quality and production efficiency of electrolytic copper foil.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0021] See also Figure 1 A preferred embodiment of a continuous quantitative addition device for activated carbon is provided. In this embodiment, the device is used to filter the electrolyte of the electrolytic copper foil during the circulation process, and the activated carbon used for the filtering operation utilizes the pore size and the permeability of organic matter passing through the pores to achieve the adsorption purpose.

[0022] The device includes a stirring barrel 3, which is a vertical structure. The lower part of the stirring barrel 3 can be held in position by a stand or a fixed seat. The top of the stirring barrel 3 is open, and a fixed cover is provided at the opening position. A feeding port is provided on one side of the fixed cover. A surface cover 2 is hingedly connected to the feeding port to facilitate closing and opening of the feeding port, thereby adding activated carbon and observing the inside of the stirring barrel 3.

[0023] Inside the mixing barrel 3, an agitator 5 is provided, and the agitator 5 is connected to the agitator motor 1 through the agitator shaft 4. The agitator motor 1 is fixedly assembled on the top surface of the fixed cover plate of the mixing barrel 3 through the motor bracket, drives the agitator shaft 4 to rotate, and then drives the agitator 5 to perform a stirring operation. The structure of the agitator 5 can adopt a paddle-type design to better achieve uniform mixing of activated carbon powder and water. At the same time, the agitator motor 1 adopts a variable frequency motor, and the stirring speed can be adjusted as needed, so as to better control the dispersion effect of the activated carbon.

[0024] The agitator 5 structure in the mixing barrel 3 keeps stirring during operation to ensure the suspension of the activated carbon powder in the water, and ensures that the activated carbon powder is uniform in the water without being deposited and sticking to the bottom of the mixing barrel 3, so as to facilitate daily cleaning by employees, and effectively avoid pipeline blockage caused by uneven distribution when the activated carbon is injected.

[0025] In another embodiment, the device may also be provided with a raw material batching structure, which includes an activated carbon tank, a water supply pipeline and a batching device; the activated carbon tank is connected to the feeding port of the mixing barrel 3 through a feeding pipeline with a powder pump, and the water supply pipeline is connected to the feeding port of the mixing barrel 3, and the batching device is an electrically controlled structure, which is electrically connected to and controlled by the powder pump on the feeding pipeline and the water pump on the water supply pipeline. The batching device can control the feeding amount of the powder pump and the water supply pipeline by controlling the opening degree and opening time of the powder pump and the water pump according to the set ratio, thereby achieving a precise ratio of activated carbon and water.

[0026] The bottom of the mixing barrel 3 is provided with a discharge port 6, which is connected to the diatomaceous earth filter through a pumping pipeline. The pumping pipeline is provided with a metering pump 7, which can control the feeding frequency by manual control, thereby realizing continuous quantitative addition of activated carbon.

[0027] In another embodiment, the metering pump 7 can also be connected to a timing controller or have a built-in timing controller to automatically implement the above-mentioned manual control operation through the timing controller, so as to accurately control the feeding time and feeding amount of the metering pump 7 while further improving the intelligence and stability of the device.

[0028] In addition, considering that the adsorption capacity of activated carbon is related to the solution temperature, the higher the solution temperature, the stronger the adsorption capacity of activated carbon; but when the solution temperature reaches above 30°C, the adsorption capacity reaches its limit and tends to gradually decrease. The stirring barrel 3 can be temperature controlled to ensure that the temperature of the solution entering the diatomaceous earth filter is around 30°C. A heat preservation structure can also be provided on the stirring barrel 3, which can be a heat preservation interlayer or an electric heating unit. The heat preservation interlayer heats and stirs the stirring barrel 3 by providing heat preservation material on the outer wall of the stirring barrel 3, thereby maintaining a uniform dispersion state of the activated carbon in the water.
