Description

Technical Field

[0001] The utility model relates to a split-type soft connection bracket which is easy to assemble and disassemble. Background Art

[0002] The ring roller mill crushes the material by the principle of impact, rolling and grinding. There is a certain gap between the grinding wheel installed on the grinding wheel frame and the grinding pin. When the grinding wheel frame revolves with the main shaft, the grinding wheel rotates by the centrifugal force and is thrown to the grinding ring and pressed against the inner wall of the grinding ring, forming a grinding force. When the material passes through the gap between the grinding wheel and the grinding ring, it is impacted, squeezed, ground and crushed by the grinding wheel. The crushed material falls to the throwing plate under the action of gravity and is thrown to the air flow channel (the air flow is generated by the matching centrifugal fan), enters the grading chamber for classification, and qualified fine powder enters through the grading wheel and is collected by the collection system. The coarse powder is thrown to the inner wall of the drainage ring and falls back into the crushing chamber for crushing. The grinding method of this type of mill usually produces large vibrations due to the action of centrifugal force. The grading part and the main machine part need to be set separately to avoid the main machine working vibration interfering with the smooth operation of the classifier, such as the ring roller mill disclosed in the patent document with announcement number CN208526808U. However, there are still some problems, especially when the main machine needs to be regularly maintained or the internal grinding equipment needs to be replaced due to aging, that is, it is necessary to first remove dozens of connecting bolts connecting the grading part and the frame, and then use a crane to lift the grading part away. Removing the bolts is extremely inconvenient, inefficient, and consumes a lot of manpower. In addition, the bottom of the lifted extension part has no support and is inconvenient to place, and is easily damaged, which urgently needs to be improved. Utility Model Content

[0019] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0020] like Figures 1 to 7As shown, a split flexible connection bracket that is easy to disassemble and assemble includes a lower support frame 1 and a flexible connection frame 3 connected to the top of the lower support frame for fixing the grading cylinder 2. The flexible connection frame includes a connecting platform 4 and a connecting leg 5 fixedly connected to the lower side of the connecting platform for connecting to the lower support frame. The lower end of the connecting leg and the upper end of the lower support frame are fixed with a flange 6, and the flanges are fitted and fastened with bolts 7.

[0021] In an embodiment of the present invention, the lower support frame is in the shape of a prism with a smaller upper portion and a larger lower portion, and the connecting legs all extend obliquely outward to connect with the lower support frame at the same inclination, making the connection, installation and support more stable.

[0022] In the embodiment of the present invention, a through opening 9 is provided in the middle of the connecting platform for connecting the upper grading cylinder and the ring roller mill 8 in the lower support frame. A plurality of connecting holes 10 for fixing to the upper grading cylinder are provided in a circular array on the connecting platform. The ring roller mill includes a grinding frame driven to rotate by a main motor and a grinding wheel that is ground by centrifugal circulation in the grinding frame. A grading wheel for screening the ground particles and an air flow channel for discharging the material are provided in the grading cylinder. These are all common settings and will not be described in detail here. The upper end of the ring roller mill needs to be connected to the grading cylinder to output or reflux the crushed material for re-grinding, but the two are not fixedly connected and there is a gap, that is, the upper end of the ring roller mill and the lower end of the grading cylinder are covered with a rubber annular sleeve 11 to prevent air from entering and exiting. The rubber annular sleeve is fastened to the ring roller mill and the grading cylinder.

[0023] In the embodiment of the present invention, a plurality of fastening holes 12 are vertically opened in an annular array on the flange, and bolts are passed through the fastening holes for connection and fastening.

[0024] In the embodiment of the present invention, a ladder 13 is fixed on the lower support frame to facilitate climbing, and multiple ladders can be provided to facilitate the removal of bolts for lifting.

[0025] The working principle of the embodiment of the utility model is as follows: when the grinding wheel needs to be replaced or maintenance needs to be carried out, the disassembly can be completed by removing the bolts on the flange, and the ring roller mill can be maintained by hoisting the grading cylinder and the soft connectors. There is no need to remove the many connectors connecting the original grading cylinder and the frame, which saves manpower. In addition, the displacement support after hoisting is more stable, and maintenance is more convenient and efficient.

[0026] The present invention is not limited to the above-mentioned best embodiment. Anyone can come up with other forms of split flexible connection brackets that are easy to disassemble and assemble based on the inspiration of the present invention. All equivalent changes and modifications made within the scope of the patent application of the present invention shall fall within the scope of the present invention.
