Abstract

This invention discloses an automatic tungsten ore refining and beneficiation equipment, including a beneficiation chamber. A control console is located on the top of the chamber, with a main motor connected to the center of a turntable. Several sets of spring seats are evenly distributed on the turntable, each set vertically connected to both sides of a separating hopper. A gate assembly is located at the bottom of the separating hopper. When the separating hopper rotates to the feeding position, the hopper opening is below the crusher discharge port. Vibrators on both sides of the crusher base plate contact the spring seats. The separating hopper's discharge port connects to a circulating water tower, and a liquid injection platform on one side of the circulating water tower rises into the gate assembly. When the separating hopper rotates to each discharge position, the gate assembly connects to the material outlet on the top of the beneficiation chamber, and a shaking table mechanism is located below the material outlet. Each position is equipped with a probe facing the transparent wall of the separating hopper. This equipment, through the cooperation of the liquid injection platform and the vibrators, generates a vertically alternating water flow within the separating hopper, causing mineral particles with different specific gravities to stratify within the hopper. The material is then discharged in batches above the shaking table mechanism using color-detecting probes, thus improving beneficiation efficiency.

Description

Technical Field

[0001] This invention relates to the field of tungsten ore processing equipment technology, specifically to an automatic ore beneficiation equipment for tungsten ore refining. Background Technology

[0002] Mineral beneficiation, also known as mineral processing, refers to the separation of various minerals and useless impurities (such as gangue) from mineral raw materials using physical or chemical methods. It is the most crucial step in the entire mineral production process, effectively improving the quality of mineral raw materials, reducing the difficulty of further processing, lowering transportation and processing costs, and enabling the comprehensive utilization of mineral raw materials. This is particularly important for ores with low mineral content, such as tungsten, which must be beneficiated and enriched into concentrate before it can be used as a raw material for smelting. Currently, tungsten ore beneficiation involves multiple steps, including crushing and grinding, settling and classification, and shaking table fine separation. These steps are completed by a combination of various equipment, requiring continuous transfer of minerals between different devices during operation. This results in poor equipment integration, dust generation and waste, and affects beneficiation efficiency. Especially in the settling and classification stage, the fluctuation of ore composition makes it difficult to accurately separate the classified ore particles, directly impacting subsequent beneficiation results. A new type of equipment is needed to solve these problems. Summary of the Invention

[0022] In this embodiment, a spraying device is provided above the shaking table 33. The spraying device includes a distribution box 39, which is connected to the output end of the spraying pump 40.

The drain connector 4202 can be connected to the circulating water tower 8 through a water pump.

[0023] The working principle of this invention is as follows: The main motor 3 is started, driving the turntable 4 to rotate and moving the corresponding jump bucket 6 to the feeding position. The roller motor 18 is started, driving each roller to rotate. The tungsten ore fed into the crusher is first crushed by the crushing roller 17 and the uppermost transport roller 16, and then rolled and transported by the double-layer transport roller 16 to the grinding roller 15 for further grinding. Finally, the ground ore falls into the bucket as particles. At the same time, the roller motor 18 drives the vibrator to strike both sides of the jump bucket 6, causing it to vibrate vertically. The lifting motor 25 drives the injection cylinder 26 to rise into the discharge pipe 602, and the injection pump 28 is started to inject water into the bucket from bottom to top. The resulting vertical alternating water flow causes mineral particles with different specific gravities to stratify in the bucket. The wastewater overflowing from the discharge port 601 flows into the circulating water tower 8 through the flow plate 22 and is purified by the filter box 23.

[0024] During the above process, probe 9 monitors in real time through the transparent bucket wall. After the particle stratification stabilizes, the injection pump 28 is turned off, and the drain pipe 2801 is opened to drain the remaining liquid in the bucket. Then, the roller motor 18 is turned off to stop the vibration. The jumping bucket 6 rotates with the turntable 4 to the adjacent discharge station. The drive motor 12 is started to retract the upper perforated plate 11. The mineral particles pass through the lower perforated plate 11 and fall into the shaking table 33 below. During unloading, the drive motor 12 can drive the lower perforated plate 11 to shake back and forth to prevent the mineral from clogging. The shaking table motor 36 is started. With the cooperation of the cam and the return spring 35, each shaking table 33 slides back and forth on the roller seat 29. The spray pump 40 is started to spray clean water from the circulating water tower 8 onto the head of the shaking table 33. The mineral falling into the shaking table 33 is asymmetrically shaken with the water flow, thereby further stratifying. When probe 9 detects that all the mineral particles in the layer have been unloaded, the upper orifice plate 11 is closed again, and the jump-dividing bucket 6 rotates with turntable 4 to the next discharge station to continue the stacking and unloading.

[0025] After the equipment has been running for a period of time, it can uniformly process the mineral residue in the flow plate 22, filter box 23, filter screen 4201, and waste liquid collection tank, avoiding waste and pollution. This invention, through the cooperation of the injection platform and the vibrator, generates a vertically alternating water flow in the jumping hopper 6, causing mineral particles with different specific gravities to stratify within the hopper. Then, a colorimetric probe is used to separate and unload the material above the shaking table mechanism. The equipment continuously loads and unloads through the rotating multiple jumping hoppers 6, featuring full automation and high integration, greatly improving mineral processing efficiency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
