Description

Technical Field

[0001] This utility model belongs to the field of mixed acid purification technology, and specifically relates to a mixed acid separation device. Background Technology

[0002] With the development of the chemical industry, various acid mixtures are generated during the production process. Some acidic substances are toxic and harmful after discharge, while others can be recycled to reduce costs and protect the environment. For example, the manufacturing process generates mixed acids containing waste sulfuric acid and waste phosphoric acid. The indiscriminate discharge of these waste liquids not only causes environmental and water pollution, but also wastes various organic and inorganic acids in the waste liquids. Therefore, it is very important to obtain a mixed acid separation device. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a mixed acid separation device, including a separation device shell, and at least one set of partition assemblies fixed inside the separation device shell. The partition assembly includes a first partition and a second partition arranged at an angle, with the first partition and the second partition having different angles. The first partition and the second partition sequentially divide the separation device shell into a first chamber, a second chamber, and a third chamber. The bottom of the inclined surface of the first partition and the second partition are each provided with an outlet. The side walls of the first chamber, the second chamber, and the third chamber are each provided with a separating agent addition port. Each outlet is equipped with a control valve. The first chamber, the second chamber, and the third chamber are each divided into upper and lower parts, which are detachably connected by flanges.

[0004] Each chamber has a filter element at the bottom, which is a filter screen and covers the outlet.

[0005] Through the above technical solution, the mixed acid of this utility model is first placed in the first chamber. After the first separating agent is added, the first acidic ion is precipitated. Then, the control valve is opened and not closed. The remaining liquid flows to the second chamber. After the second separating agent is added, the second acidic ion is precipitated. The solid substance is filtered through the filter element. The control valve of the second chamber is opened and not closed. Since there may be gas during the reaction, an exhaust one-way valve is provided at the top of the first chamber. The exhaust one-way valve includes: a guide channel opened at the top of the first chamber, and a valve plate configured in the guide channel and axially movable in the guide channel. The top of the valve plate has a sealing ring integrally formed, and the bottom has a limiting ring integrally formed. The first chamber located outside the limiting ring has a plurality of vent holes. An installation component is detachably connected to the inner wall of the first chamber. The installation component has a groove. The filter adsorption packing is fixed in the groove. A cover plate can be fixed at the top of the groove. The cover plate has small holes to prevent leakage of the filter adsorption packing. The filter adsorption packing covers all the vent holes.

[0006] Based on the above structure, the gas can be discharged from the exhaust check valve, and the filter adsorption packing can be a weakly alkaline packing, which can partially neutralize the volatile acidic gas or the gas generated by the reaction.

[0007] The partition assembly has several groups arranged linearly, and can be configured according to requirements.

[0008] When the precipitated solid is needed, it can be removed by opening the flange.

[0009] The outlet is threaded with a plug to prevent gas leakage during the reaction.

[0010] The bottom of the outer shell of the separation device is provided with an inclined surface, and a waste liquid outlet is opened at the bottom of the inclined surface.

[0011] It also includes a workbench, a first hinge is fixed to the bottom of the housing of the separation device, and a second hinge is fixed to the workbench. The first hinge and the second hinge are hinged together. It also includes a first electric telescopic rod and a second electric telescopic rod. The two ends of the first electric telescopic rod are respectively hinged to the housing of the separation device and the workbench. The two ends of the second electric telescopic rod are respectively hinged to the housing of the separation device and the workbench. The first electric telescopic rod and the second electric telescopic rod are respectively placed on both sides of the first hinge.

[0012] Through the above technical solution, the first and second electric telescopic rods of this utility model can extend and retract sequentially, that is, the outer shell of the separation device can swing, thereby increasing the mixing reaction effect.

[0013] The filter element is filter paper.

[0014] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure and can realize the separation of mixed acidic liquids. Attached Figure Description
