Acid pickling device for laboratory

Abstract

The invention relates to an acid pickling device for a laboratory. The acid pickling device comprises a pickling bath, a fluoroplastic magnetic drive pump, an acid mist absorption cover, a suction fan, an acid mist collection vessel, a cover plate and a heating device inserted into the pickling bath, wherein the acid mist absorption cover is arranged above the pickling bath; a suction port and an air outlet of the suction fan are connected with a suction pipe and an air outlet pipe respectively; one end of the air suction pipe extends into the acid mist absorption cover to be communicated with the acid mist absorption cover; one end of the air outlet pipe is communicated with the acid mist collection vessel; an acid liquor draining hole and an acid liquor entering hole are symmetrically formed in two side walls of the pickling bath and connected with a suction port and a drain port of the fluoroplastic magnetic drive pump respectively through an acid liquor conveying pipe; an acid mist discharge port is further formed above one side wall of the pickling bath and is connected with an acid mist conveying pipe communicated with the acid mist collection vessel. The acid pickling device for the laboratory is compact in structure, high in acid pickling efficiency, good in energy saving and environmental protection property and suitable for acid pickling device in the laboratory, and cleaning acid liquor can flow circularly.

Description

technical field [0001] The invention belongs to the technical field of pickling equipment, and in particular relates to a laboratory pickling device. Background technique [0002] Pickling is the most commonly used method for cleaning metal surfaces. Pickling solutions generally include hot solutions of sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, and hydrofluoric acid, so acid mist is an inevitable product in the pickling process, so It will inevitably lead to harsh working environment and serious air pollution, and the existing pickling equipment cannot be effectively used in the experiment due to problems such as excessive volume, low pickling efficiency, poor pickling effect, and the inability to effectively collect the generated acid mist. in the room. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a laboratory pickling device, the cleaning acid can be circulated,...
