Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing equipment, in particular to a repair structure for a bottom plate of a flotation machine tank. Background Art

[0002] Flotation machine is the abbreviation of flotation ore dressing machine, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the pulp treated with reagents is stirred and aerated, so that some mineral particles are selectively fixed on the bubbles, float to the surface of the pulp and are scraped out to form foam products, and the rest are retained in the pulp to achieve the purpose of separating minerals. During the operation of the flotation machine, the impeller in the center rotates and stirs, which will flow a large amount of pulp from the center to the surroundings. Therefore, during the flow of pulp, the center bottom plate of the flotation machine tank is seriously worn. In addition, since the flotation machine is in a corrosive pulp environment for a long time, the bottom plate of the tank is easily cracked due to wear and corrosion, causing the bottom plate to leak pulp. In addition, the tank of the flotation machine is located on a concrete foundation, and the bottom plate of the tank is in close contact with the concrete foundation, making it difficult to repair the bottom plate of the tank from the outside. Utility Model Content

[0003] The utility model provides a repair structure for a flotation machine tank body bottom plate, aiming at repairing the flotation machine tank body bottom plate which is easy to wear and tear, and improving the service life of the flotation machine tank body.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A flotation machine cell bottom plate repair structure comprises a flotation machine cell bottom plate located on a concrete foundation, a repair hole penetrating the cell bottom plate is opened in the middle of the flotation machine cell bottom plate, a fixed layer and a wear-resistant layer are filled inside the repair hole, and the fixed layer is located between the flotation machine cell bottom plate and the wear-resistant layer to fixedly connect the flotation machine cell bottom plate and the wear-resistant layer.

[0006] According to the above scheme, after the bottom plate of the flotation machine cell is worn, a repair hole penetrating the bottom plate of the flotation machine cell is opened in the middle of the bottom plate of the flotation machine cell, a fixing layer is first poured into the repair hole, an area for placing the wear-resistant layer is reserved in the middle of the fixing layer, and then the wear-resistant layer is embedded in the middle of the fixing layer. Finally, the fixing layer and the wear-resistant layer are laid to form a whole, thereby completing the repair of the bottom plate of the flotation machine cell and improving the service life of the flotation machine cell. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 2 It is a schematic diagram of the repair state of the utility model;

[0009] Figure 3It is an enlarged view of the repair structure of the utility model. DETAILED DESCRIPTION

[0010] like Figures 1 to 3 The repair structure of a flotation machine cell bottom plate shown in the figure comprises a flotation machine cell bottom plate 10 located on a concrete foundation 40, a repair hole 11 penetrating the cell bottom plate 10 is opened in the middle of the flotation machine cell bottom plate 10, the interior of the repair hole 11 is filled with a fixed layer 20 and a wear-resistant layer 30, and the fixed layer 20 is located between the flotation machine cell bottom plate 10 and the wear-resistant layer 30 to fixedly connect the flotation machine cell bottom plate 10 and the wear-resistant layer 30.

[0011] In the above scheme, when the bottom plate 10 of the flotation machine cell is cracked due to wear and corrosion, a repair hole 11 penetrating the bottom plate 10 is firstly opened in the middle of the bottom plate 10 of the flotation machine cell, and then the fixing layer 20 is filled into the repair hole 11, and an area for placing the wear-resistant layer 30 is reserved in the middle of the fixing layer 20, and finally the wear-resistant layer 30 is embedded in the fixing layer 20. The wear-resistant layer 30 directly contacts the ore pulp, which can extend the service life of the bottom plate of the flotation machine cell and improve the service life of the flotation machine cell.

[0012] The further fixed layer 20 is located at the side and bottom of the wear-resistant layer 30 , and fixedly connects the bottom plate 10 of the flotation machine tank and the wear-resistant layer 30 .

[0013] In the above scheme, the fixed layer 20 surrounds the side and lower part of the wear-resistant layer 30. The fixed layer 20 is wear-resistant cement, and the wear-resistant layer 30 is a steel plate. The steel plate cannot be directly welded to the bottom plate 10 of the flotation machine tank. Therefore, wear-resistant cement is selected as the fixed layer 20. While providing a leveling foundation, it plays a role in connecting and fixing the bottom plate 10 of the flotation machine tank and the wear-resistant layer 30.

[0014] Preferably, after the wear-resistant layer 30 is embedded in the fixed layer 20, the fixed layer 20 is leveled to ensure that the upper surface of the wear-resistant layer 30 is flush with the upper surface of the flotation machine tank bottom plate 10 to ensure the normal operation of the grinding flotation system.

[0015] The specific operation process is as follows:

[0016] 1. A repair hole 11 penetrating the bottom plate 10 of the flotation machine tank is opened at the damaged part of the bottom plate 10 of the flotation machine tank;

[0017] 2. Pour wear-resistant cement and level it as a fixed layer 20;

[0018] 3. Embed a steel plate in the wear-resistant cement as a wear-resistant layer 30;

[0019] 4. Ensure that the upper surface of the wear-resistant layer 30 is flush with the upper surface of the bottom plate 10 of the flotation machine tank, and scrape off the excess wear-resistant cement to achieve the repair of the bottom plate 10 of the flotation machine tank.
