Description

Technical Field

[0001] The utility model relates to the technical field of mixing, in particular to an opening and closing mechanism of a mixing tank. Background Art

[0002] In sewage treatment, it is necessary to mix the chemicals first. The lower end of the mixing tank currently used is provided with a feed pipe, and the lower end of the feed pipe is provided with an opening and closing valve, and there is a certain distance between the opening and closing valve and the mixing tank. That is to say, when the chemicals are dissolved in the feed pipe, the chemicals can enter it, while the part of the chemicals that enter the upper part of the feed pipe cannot be stirred by the stirring mechanism, so this part of the chemicals is dissolved at a slow speed or not dissolved. When the opening and closing valve is opened, this part of the chemicals will be discharged. Since the chemicals are completely dissolved, problems such as clogging of the liquid outlet head are prone to occur. Utility Model Content

[0003] The utility model provides an opening and closing mechanism for a mixing tank to solve the above-mentioned deficiencies of the prior art, facilitate the discharge of dissolved materials, and avoid the discharge of undissolved medicines, thus having strong practicality.
