Description

Technical Field

[0001] The utility model relates to the field of stirring devices, in particular to a stirring device for a heat treatment water tank. Background Art

[0002] Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but rather changes the internal microstructure of the workpiece or the chemical composition of the workpiece surface to give or improve the performance of the workpiece. Its characteristic is to improve the intrinsic quality of the workpiece, which is generally not visible to the naked eye. In order to make the metal workpiece have the required mechanical properties, physical properties and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment processes are often indispensable. Steel is the most widely used material in the machinery industry. The microstructure of steel is complex and can be controlled by heat treatment, so the heat treatment of steel is the main content of metal heat treatment. In addition, aluminum, copper, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different performance. Quenching is the most common means of heat treatment. At present, many factories will lay compressed air pipelines at the bottom of the heat treatment pool, and use compressed air to promote the circulation of cooling water in the pool to achieve the purpose of rapid cooling and quenching of the products. However, since the compressed air pressure drops quickly, the air compressor needs to work to increase the pressure, and a continuous supply cannot be achieved. Therefore, the quenching effect of the product is not very ideal.

[0003] According to a heat treatment water pool stirring device provided by patent application number CN202022241338.X, it belongs to the field of heat treatment equipment. A heat treatment water pool stirring device includes a heat treatment pool, a barrier net is installed in the middle of the heat treatment pool, and a plurality of submersible mixers located outside the barrier net are installed at equal distances on the inner bottom wall of the heat treatment pool, a filter pocket is installed on the inner wall of the heat treatment pool, and an installation groove is opened on the inner bottom wall of the center of the heat treatment pool, a collection basket is placed in the installation groove, and a filter net is provided at the bottom end of the collection basket, and a plurality of detection components located in front of the submersible mixer are installed at equal distances on the inner wall of the heat treatment pool. The utility model installs multiple submersible mixers in the heat treatment pool to drive water circulation, which improves the uniformity of water flow temperature, and the surface hardness of the quenched product is more uniform than before, and the hardness of each position is higher after treatment. In addition, it is convenient to clean the heat treatment pool and detect faults.

[0004] There are still some deficiencies in the patent application. The patent does not effectively control the range of metal chips produced by quenching. When the stirring device is working, the fast-flowing water makes it difficult for the metal chips to form deposits for collection. As the metal chips in the water flow increase, the stirring device will be damaged and cause jamming. Therefore, a heat treatment water tank stirring device is needed to solve this problem.
