[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-Figure 5 A high-sealing turbine sand mill comprises: a grinding cylinder 1, a control panel 4 and a turbine sand mill body 5; an end cover connecting mechanism 6, comprising an end cover flange shell 601, and positioning sleeve holes 603 are opened on the inner sides of both ends of the end cover flange shell 601, and the end cover flange shell 601 is arranged on the outer side of the front end of the grinding cylinder 1 to achieve positioning sleeve connection for installation; a discharging end cover mechanism 3, comprising a flange sealing cover plate 302, and the flange sealing cover plate 302 is installed and connected to the end cover connecting mechanism 6 by screws; a quick positioning mechanism 2, comprising a positioning pin 204 and a positioning sleeve 205, and a positioning pin 204 is arranged on the inner side of the positioning sleeve 205, and the positioning pin 204 is arranged on the inner side of the outer end of the end cover connecting mechanism 6 to achieve quick disassembly and assembly of the installation; a tight positioning mechanism 7, comprising a high-sealing rubber ring 701, and the high-sealing rubber ring 701 is arranged on the inner side of the end cover connecting mechanism 6 to achieve a positioning sealing effect.

[0028] The turbine sand mill body 5 can be set for grinding through the control panel 4. The front end of the grinding cylinder 1 passes through the end cover flange shell 601 of the end cover connecting mechanism 6, so that the flange sealing cover plate 302 can be installed accordingly. The flange sealing cover plate 302 and the end cover flange shell 601 are sealed by a high-sealing rubber ring 701 of the positioning and tightening mechanism 7 to avoid overflow and leakage. The quick positioning mechanism 2 can quickly position the positioning and tightening mechanism 7 on the inner side of the end cover flange shell 601, so that it can be quickly installed.

[0029] A tight mechanism positioning sleeve cavity 602 is provided in the middle of the end cover flange shell 601, so that the tight positioning mechanism 7 can be installed in a corresponding sleeve connection.

[0030] A discharge pipe 303 is welded and fixed in the middle of the inner side of the flange sealing cover 302, and a discharge filter cover 304 is screwed to the inner end of the discharge pipe 303, so that the material filtered out by the discharge filter cover 304 can be discharged to the outside through the discharge pipe 303. A carrying handle 301 is fixed in the middle of the upper end of the flange sealing cover 302 to facilitate personnel to hold and carry for installation.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an inner positioning sleeve 704 is sleeved on the inner side of the high-sealing rubber ring 701, and the inner positioning sleeve 704 passes through the high-sealing rubber ring 701 on the outer side. The high-sealing rubber ring 701 is sleeved and connected in the end cover flange shell 601, thereby effectively improving the assembly sealing performance of the inner positioning sleeve 704 and the end cover flange shell 601, so that the inner positioning sleeve 704 is tighter after being inserted, and a positioning convex plate 702 is fixedly connected between the upper ends of the high-sealing rubber ring 701 and the inner positioning sleeve 704. When inserted, the positioning convex plate 702 can be used for positioning and sleeve connection, so that the overall installation position corresponds, thereby facilitating installation and fixation. After insertion, since a positioning hole 703 is opened on the inner side of the positioning convex plate 702, the quick positioning mechanism 2 can be quickly positioned, thereby facilitating stable installation in the later stage.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, the upper end of the positioning pin 204 passes through the positioning sleeve 205 and is movably sleeved with a T-shaped movable column 202, so that when the movable wrench block 201 vertically contacts the upper end of the positioning sleeve 205, the T-shaped movable column 202 can be positioned and moved upward in the positioning sleeve 205, and the T-shaped movable column 202 can drive the positioning pin 204 to be positioned and moved upward in the positioning sleeve 205, and the lower end of the T-shaped movable column 202 is located in the positioning sleeve 205 and is sleeved with a resistance spring 203. The spring 203 can elastically resist the positioning column 204, and the upper end of the T-shaped movable column 202 is sleeved with an adjustable wrench block 201. When the adjustable wrench block 201 is rotated and laid flat, the resisting spring 203 resists the positioning column 204, and the positioning column 204 drives the T-shaped movable column 202 to move downward, so that the positioning column 204 inside the positioning sleeve 205 can be inserted into the end cover connecting mechanism 6, and the positioning column 204 can be inserted into the positioning hole 703 for quick positioning.

[0033] The welding connection between the positioning sleeve 205 and the end cover connecting mechanism 6 is connected, so that the positioning pin 204 can be inserted through for positioning. The positioning pin 204 is sleeved in the end cover connecting mechanism 6 through the resistance spring 203, and can be elastically resisted by the resistance spring 203 for quick positioning.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
