Constant-temperature ball mill

Abstract

The invention discloses a constant-temperature ball mill, which comprises a frame, and the frame is provided with a driving device, a ball mill protective cover, a temperature control box and a controller, wherein the ball mill protective cover is internally provided with a ball mill tank driven to rotate by the driving device and a temperature sensor connected with the controller, the ball mill protective cover is provided with a protective cover air inlet and a protective cover air outlet, and the temperature control box is provided with a temperature control air outlet and a temperature control air inlet which are respectively connected with the protective cover air inlet and the protective cover air outlet; the temperature control box is internally provided with a refrigerating part connected with the controller and / or a heating part connected with the controller and a circulating fan enabling air to circulate between the ball mill protective cover and the temperature control box,and the refrigerating power of the refrigerating part or the heating power of the heating part is controlled by the controller according to signals of the temperature sensor. According to the invention, monitoring signals of the temperature sensor can be obtained in real time by the controller, and the refrigerating power of the refrigerating part or the heating power of the heating part is controlled according to signals of the temperature sensor and the requirement of the grinding environment temperature, so that the temperature required by the grinding material in the grinding process can be better met.

Description

technical field [0001] The invention belongs to the technical field of ball mills, and in particular relates to a constant temperature ball mill. Background technique [0002] The ball mill is mainly designed for crushing or grinding powders such as dispersing metals, non-metals, Chinese herbal medicines, cosmetics, and electronic products. Most of the ball mills work in the normal temperature environment. When the ball mill is grinding, it will encounter various demands on the grinding environment temperature or problems about the grinding environment temperature due to the different grinding materials. For example: in the grinding materials of some industries Some catalysts are used, and some catalysts are more sensitive to the temperature index of the grinding environment of the ball mill; when the ball mill is used for mixing chemical raw materials, the chemical raw materials need an appropriate temperature environment as the prerequisite for their physical state; Or th...

Problems solved by technology

[0003] In view of the above situation, the usual method is to manually touch the temperature of the ball milling tank, and manually spray water to the ball milling tank to cool it down. This method has low production cost but also low work efficiency, and it is not easy to control the temperature of the grinding environment. Therefore, There are liquid nitrogen ball mills, air-cooled ball mills, etc., such as: a refrigerated liquid nitrogen ball mill with a Chinese patent application number of CN201811276172.6. Liquid nitrogen is provided in the ball mill tank to cool down the grinding materials in the ball mill tank. However, its use conditions are relatively strict, and the equipment manufacturing and processing require high sealing. If the ball mill tank encounters high heat, the internal pressure of the container will increase, and there is a risk of cracking and explosion. , this type of liquid nitrogen ball mill is mainly to solve the demand for low-temperature grinding environment of tough grinding materials such as plastics and resins. It is inconvenient to control the stability of the grinding environment temperature, and cannot meet the grinding requirements of grinding materials that are sensitive to the grinding environment temperature.
