Description

Technical Field

[0001] The utility model relates to the technical field of bauxite processing, in particular to a low-grade bauxite washing device. Background Art

[0002] As an important industrial raw material, bauxite is widely used in many fields. With the rapid development of industry, the demand for bauxite continues to grow. Different industrial applications have specific requirements for the quality of bauxite, and bauxite that has not been fully cleaned often cannot meet these requirements. For example, in the aluminum smelting industry, high-quality bauxite can improve smelting efficiency, reduce energy consumption and reduce the damage of impurities to equipment. In the field of building materials, bauxite can be processed to produce refractory materials, ceramics, etc. If the bauxite contains too many impurities, it will affect the refractory properties of the refractory materials and the quality of the ceramics. In the chemical industry, bauxite can be used as a catalyst or raw material for certain chemical reactions. Unwashed bauxite may introduce unnecessary impurities, affecting the efficiency of the chemical reaction and the purity of the product.

[0003] Some of the current bauxite washing devices have the problem of insufficient cleaning during the cleaning process, which affects the quality of the bauxite and subsequent processing and utilization. The simple water flushing method cannot effectively remove various fine impurities and stubborn attachments mixed in the bauxite. This will not only lead to lower product quality in subsequent smelting, chemical and other industrial applications of bauxite, but also increase equipment wear and energy consumption due to the presence of impurities. Therefore, a low-grade bauxite washing device is proposed to solve the above problems. Utility Model Content

[0034] Reference Figure 1 、 Figure 3 and Figure 4 The screening assembly includes a sieve plate 14, which is made of high-strength aluminum alloy, has a light weight and good strength, and can withstand the weight of bauxite and the vibration during the screening process. The rear end of the sieve plate 14 is arranged at the front end of the cleaning barrel 1, and the interior of the sieve plate 14 is fixedly connected with a screen 15. The screen 15 is made of stainless steel, has good wear resistance and corrosion resistance, and can effectively screen bauxite. A plurality of support columns 16 are provided at the bottom end of the sieve plate 14. The support columns 16 are made of sturdy steel and can withstand the weight of the sieve plate 14 and bauxite, ensuring the stability of the screening process. The interiors of the multiple support columns 16 are all fixedly connected with telescopic springs 22. The telescopic springs 22 are made of high-quality spring steel, have good elasticity and durability, and can provide stable support and buffering during the screening process.

[0035] The top ends of the multiple telescopic springs 22 are all fixedly connected to fixed blocks 20. The fixed blocks 20 are made of wear-resistant plastic material with good wear resistance and can be tightly connected to the telescopic springs 22 and the sieve plate 14. The top ends of the multiple fixed blocks 20 are fixedly connected to the bottom end of the sieve plate 14. The bottom end of the sieve plate 14 is rotatably connected to two transmission rods 19.

The outer portions of the two motors 17 are fixedly connected to the interior of two of the support columns 16.

[0037] Working principle: When the staff needs to clean the bauxite, the bauxite to be cleaned is transferred to the inside of the cleaning barrel 1 through the conveyor belt 12. At this time, the motor 11 is started to rotate the rotating column 2. The rotation of the rotating column 2 causes the latch 3 to drive the rotating disk 4 to rotate back and forth, so that the cleaning brush 5 brushes the surface of the bauxite. At the same time, the water pump 8 will pump the water inside the water tank 9 to make the water flow, and the bauxite is flushed with high-pressure water through the outlet pipe 7 and the outlet 6. The flushed sewage and mud will be discharged to the outside through the filter 13, thereby completing the cleaning of the bauxite. Through rapid automatic cleaning, the work efficiency and processing quality are improved.

[0038] The cleaned aluminum ore will fall into the inside of the sieve plate 14. The sieve plate 14 is tilted as a whole and has a rotation point at the front end. At this time, the motor 2 17 will start the eccentric wheel 18 to rotate back and forth, so that the transmission rod 19 pushes the sieve plate 14 back and forth to rise and fall. When descending, the support column 16 will slide inside the fixed block 20, and the fixed block 20 will squeeze the telescopic spring 22, thereby slowly descending. When rising, the telescopic spring 22 will push the fixed block 20 to rise quickly, so that the bauxite rises and falls on the screen 15, thereby completing the screening. The appropriate size will fall from the inside of the screen 15, and the too large will fall from the front end, so that it can be taken away for fine crushing for the next screening. Through screening, the consistency during processing is guaranteed, the problem of waste caused by different sizes is avoided, and the quality of the product is guaranteed.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
