Description

Technical Field

[0001] This utility model relates to the technical field of ore processing equipment, specifically to a quartz ore grading and cleaning device. Background Technology

[0002] Before being processed, quartz ore usually needs to be cleaned to remove surface dirt, dust and other impurities, and then classified by particle size according to the requirements of subsequent processes. Traditional processing methods often treat cleaning and grading as separate processes, using different equipment, such as washing tanks and agitated washing machines for cleaning, and then using vibrating screens and drum screens for grading.

[0003] The above-mentioned separation process has the problems of long process, multiple equipment, large area and high cost, and the need to transfer materials between different equipment, which increases the complexity of operation and energy consumption. Although traditional drum screens can wash and screen at the same time, they usually only have a single screen aperture, making it difficult to achieve multi-level grading and cleaning. Utility Model Content

[0004] In order to overcome the problems in the prior art, this utility model provides a quartz ore grading and cleaning device, which solves the problems of long process, many equipment and large footprint in the existing quartz ore cleaning and grading process, and realizes efficient integrated processing of cleaning and multi-level grading.

[0005] A quartz ore grading and cleaning device includes a frame, a tilting frame, a first power unit, a second power unit, and a screen cylinder. The frame is inverted U-shape. The first power unit is mounted on one arm of the frame, and a bearing mechanism is mounted on the other arm. The tilting frame is also U-shaped and rotatably mounted between the two arms of the frame, connecting the power output end of the first power unit and the bearing mechanism. The second power unit is mounted on the cross arm of the tilting frame. The screen cylinder is spindle-shaped or rugby ball-shaped with a diameter in the middle larger than the diameters at both ends. The screen cylinder is located inside the tilting frame, with one conical end connected to the power output end of the second power unit and the other conical end of the screen cylinder having a water inlet. The screen cylinder wall is provided with a screen mesh and a discharge gate. The screen mesh includes at least one fine screen mesh located in the large-diameter area in the middle of the screen cylinder and at least one coarse screen mesh located at at least one end of the screen cylinder.

[0006] Furthermore, the screen cylinder is provided with end plates at both conical ends. One end plate at one conical end of the screen cylinder is provided with a water inlet, and the other end plate at the other conical end is provided with a connecting shaft. The connecting shaft is connected to the power output end of the second power device. Several reinforcing plates are connected to the two end plates and fixed to the screen mesh.

[0007] Furthermore, the cross-section of the fine screen perpendicular to the rotation axis of the screen cylinder is a trapezoid with a narrower bottom and a larger top, and the coarse screen is connected to both sides of the fine screen.

[0008] Furthermore, the coarse screen includes a first coarse screen and a second coarse screen, which are respectively installed at one conical end of the screen cylinder, and the mesh count of the first coarse screen is smaller than that of the second coarse screen.

[0009] Furthermore, the first power unit includes a first motor that drives the tilting frame to tilt, and the second power unit includes a second motor that drives the screen cylinder to rotate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a specially shaped drum and screens with different mesh sizes arranged in sections. While the drum rotates and cleans, the tilting of the drum changes the material retention area, enabling cleaning and at least two levels of particle size classification to be completed in one device. This simplifies the process and reduces the number of devices and floor space required.

[0011] This invention provides excellent cleaning results. The rotation of the drum causes the ore to tumble and rub against each other, and come into contact with the water flow. The multi-faceted design enhances the material dropping effect, thereby improving cleaning efficiency and cleanliness.

[0012] This invention achieves more precise multi-level grading by setting screen partitions with different mesh sizes and controlling the residence time of materials in each area by controlling the tilt angle and rotation time. The rotation speed and tilt angle of the drum can be driven and controlled by a power unit. The operating parameters can be flexibly adjusted according to the particle size distribution, mud content, hardness, etc. of the ore to optimize the cleaning and grading effect. The tilting and rotation function also facilitates feeding and unloading. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] See Figure 1 , Figure 2 This utility model proposes a quartz ore grading and cleaning device, including a frame 1, a tilting frame 2 mounted on the frame 1, a first power unit 3 mounted on one side arm of the frame 1, a second power unit 4 mounted on the tilting frame 2, and a screen cylinder 5 installed inside the tilting frame 2 and driven to rotate by the second power unit 4; the frame 1 provides basic support, the tilting frame 2 is roughly U-shaped, and its two ends are pivotally connected to the output end of the first power unit 3 and the bearing mechanism 11 on the other arm of the frame 1, respectively. The first power unit 3 (such as a geared motor with self-locking) can drive the tilting frame 2 to rotate around the pivot axis, thereby changing the overall tilt angle of the screen cylinder 5 installed inside the tilting frame 2, so that it can tilt from a horizontal state to a state with one end facing down; See Figure 3 , Figure 4 The screen cylinder 5 is shaped like a spindle or a rugby ball, with a thicker middle and thinner ends. The screen cylinder 5 has end plates 51 at both ends. One end plate 51 has a water inlet 54 in the center, which is connected to an external water pipe to supply water to the inside of the screen cylinder. The other end plate 51 has a connecting shaft 52 in the center. The connecting shaft 52 is connected to the power output end of the second power device 4 (such as a geared motor) installed on the cross arm of the tilting frame 2. The second power device 4 drives the screen cylinder 5 to rotate around its central axis (i.e., the line connecting the center point of the connecting shaft 52 and the water inlet 54). The end plates 51 are connected by several axially extending reinforcing plates 53, which form the skeleton of the screen cylinder. See Figure 3 , Figure 4 The sidewall of the screen cylinder 5 is mainly composed of screen mesh and is equipped with an openable discharge gate 50 for loading and unloading quartz ore. The screen mesh is divided into areas: in the middle of the screen cylinder 5, where the diameter is largest, a fine screen 6 with a smaller mesh size is installed; in the conical area where the screen cylinder 5 narrows towards both ends, a coarse screen 7 with a larger mesh size than the fine screen 6 is installed. The coarse screen 7 can be further divided into two parts, namely a first coarse screen 71 and a second coarse screen 72 located at the two conical ends. The mesh size of these two coarse screens can be set to be the same or different according to the grading requirements. For example, the mesh size of the first coarse screen 71 is smaller than that of the second coarse screen 72, thereby achieving three-level grading of fine, medium, and coarse ore. The screen mesh is fixed by a reinforcing plate 53 and an end plate 51. The sidewall of the screen cylinder can be designed as a multi-faceted structure, for example, it can be spliced ​​together with a fine screen 6 panel with a trapezoidal cross section and a coarse screen 7 panel with a triangular or trapezoidal cross section to enhance the tumbling and lifting effect of the ore during rotation.

[0018] Work process: Feeding and primary cleaning: Drive the tilting frame 2 to a position where the screen cylinder 5 is roughly horizontal, load the quartz ore to be processed through the discharge gate 50, start the second power unit 4 to make the screen cylinder 5 rotate, and at the same time, introduce cleaning water through the water inlet 54. The ore rolls, rubs against each other and is washed by the water flow in the fine screen area 6 in the middle part of the screen cylinder 5. Fine particles, mud and wastewater smaller than the mesh size of the fine screen 6 are discharged through the fine screen 6. Secondary cleaning and grading: After a predetermined time, the first power device 3 is started to tilt the tilting frame 2 and the screen cylinder 5 so that the end with the first coarse screen 71 is facing down. The screen cylinder 5 continues to rotate and water is introduced. At this time, the ore with a size larger than the fine screen 6 moves and gathers at the lower end of the screen cylinder 5 due to gravity, that is, the area of ​​the first coarse screen 71. In this area, tumbling, cleaning and screening continue. Ore particles with a size between the fine screen 6 and the first coarse screen 71 are discharged through the first coarse screen 71. Three-stage cleaning and grading: If a second coarse screen 72 with a different mesh size is set, the first power device 3 is restarted after the second stage of treatment to tilt the tilting frame 2 in the opposite direction, so that the other end with the second coarse screen 72 is facing down. The screen cylinder 5 continues to rotate and water is introduced. The ore with a size larger than the first coarse screen 71 moves and gathers at the new downward tilting end, that is, the area of ​​the second coarse screen 72. The final cleaning and screening are carried out in this area. Ore particles with a size between the first coarse screen 71 and the second coarse screen 72 are discharged through the second coarse screen 72. Discharge: After completing all cleaning and grading steps, stop water intake and rotation, tilt the tilting frame 2 to an angle that facilitates discharge, open the discharge door 50, and discharge the fourth-grade ore that is larger than the aperture of all screens that is finally left in the screen cylinder 5.

[0019] This invention can precisely control the first power unit 3 and the second power unit 4 through the control system, and adjust the tilt angle, rotation speed and processing time of each stage to adapt to the processing requirements of different materials.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
