Description

Technical Field

[0001] The utility model relates to the field of a flotation machine stirring impeller, in particular to a self-made flotation machine stirring impeller. Background Art

[0002] In the coal washing industry, flotation machines play an important role in coal washing plants. They mainly separate coal from gangue through the flotation principle to improve coal quality. The impeller of the flotation machine mainly sucks in the slurry and the unmineralized internal circulation flow to complete the aeration and stirring of the slurry and make the bubbles have a good dispersion.

[0003] At present, the flotation agitator impeller is seriously worn out due to long-term use, and now needs to be replaced. Due to the high procurement cost, a single flotation machine consumes nearly 100,000 yuan of impellers each year. In order to reduce the cost of using the flotation machine impeller, it is necessary to develop a homemade flotation machine impeller to solve the above problem. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a self-made flotation machine agitator impeller.

[0005] The utility model is realized through the following technical solutions:

[0006] A self-made flotation machine agitator impeller comprises a supporting bottom plate and a conical cylinder fixed on its upper part, the conical cylinder can be sleeved with a bottom cover plate of an impeller, the top of the conical cylinder supports a hub of the impeller, a plurality of blades are evenly installed between the side of the hub and the bottom cover plate, a plurality of positioners for positioning the blades are installed on the conical cylinder, an upper cover plate is fixed on the upper part of the plurality of blades, and a plurality of guide vanes are evenly fixed on the upper cover plate.

[0007] Further optionally, the positioner includes two vertical limiting plates, a positioning block supporting the blade is fixed on the inner side of the center of the limiting plates, and a positioning groove is formed between the two limiting plates on the upper part of the positioning block.

[0008] Further optionally, the bottom diameter of the conical cylinder of the positioner matches the pulp inlet hole opened in the center of the bottom cover plate.

[0009] Further optionally, a boss is provided on the inner side of the top of the conical cylinder, and a slot that can be snapped into the inside of the wheel hub is formed between the boss and the conical cylinder.

[0010] Further optionally, the height of the limiting plate does not exceed the height of the corresponding blade.

[0011] Compared with the existing technology, the beneficial effects of the utility model are: the utility model uses the conical cylinder and multiple positioners on the upper part of the impeller to quickly position, assemble and fix the bottom cover plate, blades, hub and upper cover plate of the impeller. The integrally manufactured impeller is not only highly efficient but also of good quality. At the same time, the cost of the homemade impeller is greatly reduced compared to the cost of purchasing a single flotation machine impeller, thereby reducing the operating cost of the flotation machine.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0017] like Figure 1 , 3 As shown, a homemade flotation machine agitator impeller comprises a supporting bottom plate 7 and a conical cylinder 8 fixed on its upper portion, the conical cylinder 8 can be sleeved with a bottom cover plate 1 of the impeller, the top of the conical cylinder 8 supports a hub 4 of the impeller, a plurality of blades 3 are evenly installed between the side of the hub 4 and the bottom cover plate 1, a plurality of positioners for positioning the blades 3 are installed on the conical cylinder 8, an upper cover plate 5 is fixed on the upper portion of the plurality of blades 3, and a plurality of guide vanes 6 are evenly fixed on the upper cover plate 5.

[0018] like Figure 1 As shown, the positioner includes two vertical limiting plates 11 , a positioning block 12 supporting the blade 3 is fixed to the inner side of the center of the limiting plate 11 , and a positioning groove is formed between the two limiting plates 11 above the positioning block 12 .

[0019] like Figure 1 As shown, the bottom diameter of the conical cylinder 8 of the positioner matches the pulp inlet hole 2 opened in the center of the bottom cover plate 1.

[0020] like Figure 2 As shown, a boss 9 is provided on the inner side of the top of the conical cylinder 8, and a slot 10 that can be snapped into the inside of the hub 4 is formed between the boss 9 and the conical cylinder 8. The hub 4 and the axis of the bottom cover plate 1 are coaxially arranged through the positioning of the slot 10, thereby ensuring the accuracy of impeller installation.

[0021] like Figure 1 As shown, the height of the limiting plate 11 does not exceed the height of the corresponding blade 3 , so that the upper cover plate 5 will not interfere with the limiting plate 11 .

[0022] The implementation principle of a self-made flotation machine agitator impeller in the embodiment of the present application is:

[0023] When manufacturing the impeller, firstly, the bottom cover plate 1, the plurality of blades 3, the upper cover plate 5, and the guide vane 6 are cut and processed. After processing, the bottom cover plate 1 is placed on the conical cylinder 8 supporting the bottom plate 7, and the pulp inlet hole 2 of the bottom cover plate 1 is matched with the root of the conical cylinder 8. After the bottom cover plate 1 is positioned, the hub 4 is placed in the groove 10 of the boss 9 on the top of the conical cylinder 8 to achieve the positioning of the bottom cover plate 1;

[0024] Next, multiple blades 3 are vertically placed in the positioning grooves of the positioners on the corresponding conical cylinders 8, so that the bottom ends of the blades 3 fit with the upper part of the bottom cover plate 1, and the upper part of the blades 3 fit with the side of the hub 4. Through the positioning effect of the positioning grooves of the positioners, multiple blades 3 can be evenly distributed on the bottom cover plate 1, and the positioning blocks 12 in the positioning grooves support the lower part of the blades 3 to prevent them from being deflected. After the multiple blades 3 are positioned, a welding gun is used to weld them to the bottom cover plate 1 and the side of the hub 4;

[0025] After welding, the upper cover plate 5 is placed on the upper part of the plurality of blades 3 and welded to the blades 3. After welding, the guide vane 6 is welded and fixed on the upper part of the upper cover plate 5 to complete the manufacture of the flotation machine impeller. The impeller manufactured as a whole is not only more efficient but also of better quality. At the same time, the self-made impeller reduces the cost of a single flotation machine impeller by 84,000 yuan per year compared to the annual cost of purchasing a single flotation machine impeller of 16,000 yuan.
