Technical Field

[0001] The utility model belongs to the technical field of grinding wheel production equipment, and specifically relates to a material mixing device for grinding wheel production. Background Art

[0002] In the process of making grinding wheels, a mixing device is needed to stir and mix the abrasive. The uniformity of the mixing of the abrasive is one of the important factors that determine the quality of the grinding wheel. The commonly used mixing devices on the market have the following problems during use, such as: 1. Generally, a single stirring structure is used to stir the material in a single direction. This stirring method not only takes a long time to stir and mix, but also has a poor mixing effect, which affects the quality of the subsequent grinding wheel production; 2. In the process of stirring and mixing the materials, some materials will adhere to the inner wall of the stirring tank, making it difficult to mix the materials thoroughly and evenly; 3. After use, the inside of the mixing device is difficult to clean, which affects the next use.

[0003] Therefore, a new mixing device is needed to solve the above problems. Utility Model Content

[0018] To facilitate cleaning of the inner wall of the tank body 2, the rotating rod 6 is provided with a plurality of nozzles 20 connected to the interior thereof, the nozzles 20 are provided with a plurality of nozzles 21, and a partition 22 is provided in the rotating pipe corresponding to the lower portion of the nozzles 20; a water pump 18 is provided above the tank body 2, the water inlet of the water pump 18 is connected to a water supply pipe 19, the water outlet of the water pump 18 is connected to one end of a drain pipe 17, and the other end of the drain pipe 17 is rotatably connected to the top end of the rotating pipe through a rotating joint.

[0019] In order to improve the stirring and mixing efficiency of the materials, the spiral radius of the spiral stirring blade 10 gradually increases from bottom to top.

[0020] In order to facilitate the movement of the device, a plurality of supporting legs 15 are provided at the bottom of the mounting frame 1 , and a universal wheel 16 with a locking mechanism is provided at the bottom of the supporting legs 15 .
