Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sand mill cooling, in particular to a water-cooled and electric-control integrated sand mill. Background Technique
[0002] The traditional integrated sand mill uses an air-cooled frequency converter, which needs to be installed in an electric cabinet. Since the air-cooled frequency converter relies on cold air to achieve the cooling purpose, it requires air inlets and outlets for heat dissipation of the frequency converter. Therefore, it is necessary to open heat dissipation ports on the surface of the electric cabinet for the frequency converter to cool down. However, for the electric cabinet with heat dissipation ports opened, its structural strength is greatly reduced and the explosion-proof grade is low. Content of the Utility Model

[0006] To achieve the above object, the utility model provides the following technical solution: A water-cooled and electric-control integrated sand mill, including a sand mill body, on one side of which there is a frequency conversion cabinet, and inside the frequency conversion cabinet there is a water-cooled frequency converter.
[0007] On the frequency conversion cabinet, there is a main cooling water pipe, which includes a main cooling water inlet and a main cooling water outlet.
[0008] On the water-cooled frequency converter, there are respectively a frequency converter cooling water outlet and a frequency converter cooling water inlet.
[0009] The main cooling water inlet is connected to the frequency converter cooling water inlet through a water pipe, and the main cooling water outlet is connected to the frequency converter cooling water outlet through a water pipe.
[0010] As a further preferred option, the frequency conversion cabinet is of a closed integrated structure.
[0011] (3) Beneficial Effects

[0013] For this water-cooled and electric-control integrated sand mill, by improving the existing frequency converter and adopting a water-cooled frequency converter, the water-cooled frequency converter uses the water-cooling method. Compared with the air-cooled frequency converter, it does not need to exchange heat by opening heat dissipation ports. Therefore, its frequency conversion cabinet adopts a closed structure and the explosion-proof grade can reach IP65 level. Description of the Drawings

[0021] The water-cooled frequency converter 3 is provided with a frequency converter cooling water outlet 6 and a frequency converter cooling water inlet 7 .
[0022] The main cooling water inlet 4 is connected to the inverter cooling water inlet 7 through a water pipe, and the main cooling water outlet 5 is connected to the inverter cooling water outlet 6 through a water pipe (the connecting water pipe is not shown in the figure).
