[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 , an embodiment provided by the utility model:

[0022] An open grinding jar comprising:

[0023] A grinding sleeve 1, the upper surface of the grinding sleeve 1 is threadedly connected with an upper sleeve 11, the lower surface of the grinding sleeve 1 is threadedly connected with a lower sleeve 12, the grinding sleeve 1, the upper sleeve 11 and the lower sleeve 12 constitute a grinding jar, the top and bottom of the grinding sleeve 1 are open, the upper sleeve 11 and the lower sleeve 12 have the same structure, a non-metallic upper cover 2 is fixedly connected to the surface of the upper sleeve 11 and the lower sleeve 12, a long groove 21 is provided on the surface of the non-metallic upper cover 2, an anti-corrosion silicone sealing groove 23 is provided on the bottom of the non-metallic upper cover 2, a long rib 22 is snap-connected to the long groove 21, and a sealing notch 24 is provided on the surface of the upper sleeve 11.

[0024] Furthermore, the grinding sleeve 1 adopts an aluminum alloy surface oxidation process, which can effectively improve the service life of the grinding sleeve 1 and prevent rust. The grinding sleeve 1 is designed with upper and lower external threads, the upper sleeve 11 and the lower sleeve 12 are designed with internal threads, and the upper sleeve 11 and the lower sleeve 12 are knurled for easy manual tightening.

[0025] Furthermore, the upper sleeve 11 and the lower sleeve 12 are connected by the internal thread and the external thread of the grinding sleeve 1. The non-metallic upper cover 2 is made of non-metallic material. The non-metallic upper cover 2 is embedded with nylon, Teflon, agate, and tungsten carbide materials, which can withstand the impact inside the grinding sleeve 1 and has a service life higher than that of metal materials.

[0026] Furthermore, three groups of long grooves 21 are provided with a height of 2 to 3 mm, and the long ribs 22 are connected to the long grooves 21 in three groups by snapping, which can effectively reduce the friction between the grinding sleeve 1 and the upper sleeve 11 and the lower sleeve 12, and improve the service life of the upper sleeve 11 and the lower sleeve 12.

[0027] Furthermore, the non-metallic upper cover 2 is provided with an arc of R5, which can mitigate the impact of the magic ball inside the grinding sleeve 1 and fit tightly with the grinding sleeve 1.

[0028] Furthermore, an anti-corrosion silicone sealing groove 23 is provided at the bottom of the non-metallic upper cover 2. The silicone on the anti-corrosion silicone sealing groove 23 can compress the upper sleeve 11 and the lower sleeve 12 to improve the tightness of the connection between the grinding sleeve 1 and the upper sleeve 11 and the lower sleeve 12.

[0029] Furthermore, the sealing notches 24 on the upper sleeve 11 and the lower sleeve 12 leave spaces for the anaerobic sealant, and the matching tolerance is 10um to 500um, which can effectively protect the grinding sleeve 1 and the upper sleeve 11 from being damaged.

[0030] Working principle: external threads are provided on both sides of the grinding sleeve 1, and the upper sleeve 11 and the lower sleeve 12 are installed at the two ends of the grinding sleeve 1. The grinding sleeve 1 is open as a whole, which is convenient for integrated processing and reduces production costs. Three groups of long grooves 21 are opened on the non-metallic upper cover 2. By engaging the long ribs 22 on the long grooves 21, the friction between the non-metallic upper cover 2 and the grinding sleeve 1 is reduced. At the same time, the curvature of the non-metallic upper cover 2R5 can also be reduced to slow down the impact of the grinding balls, and it is closely matched with the grinding sleeve 1. At the same time, anti-corrosion silicone is installed on the anti-corrosion silicone sealing groove 23, and the upper grinding sleeve 1, the upper sleeve 11 and the lower sleeve 12 are pressed together to prevent the grinding sleeve 1, the upper sleeve 11 and the lower sleeve 12 from being corroded. The sealing notches 24 are opened on the upper sleeve 11 and the lower sleeve 12 to reduce the friction between the grinding sleeve 1 and the upper sleeve 11 and the lower sleeve 12, thereby improving the service life of the tank cover.
