Description

Technical Field

[0001] The utility model relates to the field of mineral processing equipment, in particular to a novel mineral screening vibrating screen. Background Art

[0002] In the field of mineral processing, minerals are natural elements or compounds with fixed chemical compositions and physical and chemical properties, formed in the Earth's crust by natural physical, chemical, and biological processes. Mineral processing is the process of separating useful minerals from gangue minerals to the greatest extent possible, thereby obtaining high-grade concentrates. It also involves recovering as many useful minerals as possible from the coexisting minerals into separate concentrates, removing harmful impurities, and comprehensively recovering and utilizing various useful components.

[0003] Screening is indispensable in the mineral processing industry. It can screen out fine particles from the crusher feed, increasing crusher productivity and preventing over-crushing. Before jigging and dry magnetic separation, ore is often screened into several grades based on particle size for separate processing, improving separation efficiency. In a mineral processing plant, screening can sometimes be used as selective screening, dewatering screening, or ore washing screening. Screening is an essential operation in mineral processing.

[0004] The traditional screening machine has a relatively simple screening action and its efficiency needs to be further improved. In addition, the structure is relatively complex and there are many transmission mechanisms. When it is damaged during operation, maintenance work becomes complicated and difficult.

The eccentric wheel mechanisms on the left and right side rails are arranged in pairs opposite to each other; a shaking plate is arranged above the eccentric wheel mechanism, and convex handles are respectively provided on the left and right ends of the shaking plate. The convex handles correspond to the vertical long holes opened on the four frames; a transmission sprocket mechanism is provided on the inner side of the side bars on the left and right sides, and the eccentric wheel mechanism cooperates with the transmission sprocket mechanism so that the transmission sprocket mechanism drives the rotation of the eccentric wheel mechanism, causing the shaking plate on the eccentric wheel mechanism to shake, and a screen structure for screening is provided on the surface of the shaking plate; an inclined receiving plate is installed just below the shaking plate on the frame, a bottom base plate is provided at the bottom of the frame, and a vibration motor is provided on the bottom base plate at one end of the frame to drive the frame to shake.

[0025] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] The present invention is described more fully below with reference to the accompanying drawings, which illustrate various aspects of the present invention. The present invention may be implemented in various forms and should not be construed as limited to the various aspects of the present invention presented in this implementation section. Unless otherwise defined, all terms used herein (including industry terms) have the same meanings as commonly understood by persons of ordinary skill in the art to which the present invention pertains.

[0027] Various aspects of the present invention will be described below with reference to the accompanying drawings, which are schematic illustrations of idealized configurations of the present invention. As such, variations in the shapes of these illustrations are to be expected, for example, as a result of manufacturing techniques and / or tolerances. The various aspects of the present invention shown in the drawings may not necessarily be drawn to scale. Furthermore, some of the drawings have been simplified for the sake of clarity. Consequently, the drawings may not depict all of the various components of a given apparatus (e.g., device) or method. Therefore, the components shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shape of the components and are not intended to limit the scope of the present invention.

[0028] Reference Figures 1 to 3 As shown, the new mineral screening vibrating screen described in the utility model includes a frame 1, which includes four columns 2, two side fences 3 and a bottom plate 4. The columns 2 are upright on the bottom plate 4, and the four columns 2 are distributed at the four corners of a rectangle. The four columns 2 are divided into two groups on the left and right sides in the length direction of the frame 1. A side fence 3 is horizontally mounted on the corresponding horizontal side of each group of columns 2, and the two ends of the side fence 3 are respectively vertically connected to the two columns 2 in each group.

[0029] Several eccentric wheel mechanisms 5 are arranged at intervals on the side rails 3 of the frame 1. The eccentric wheel mechanisms 5 include a support rod 6, a connecting shaft 7, a rotating wheel 8, and an eccentric support wheel 9. The support rod 6 is vertically mounted on the side rail 3. The upper part of the support rod 6 is vertically connected to the connecting shaft 7. A rotating rotating wheel 8 is arranged on the connecting shaft 7. One side of the rotating wheel 8 is the support rod 6, and an eccentric support wheel 9 is arranged on the opposite side. The eccentric support wheel 9 and the rotating wheel 8 are fixedly connected or integrally formed. Several protrusions 10 are arranged along a radial array on the outer periphery of the rotating wheel 8, and the length direction of the protrusions 10 is arranged toward the axial direction of the rotating wheel 8.

[0030] The eccentric wheel mechanism 5 is installed on the side rail 3 through the support rod 6. The side rail 3 is provided with a mounting hole at the mounting position. The support rod 6 is provided with an adjustment long hole along the length direction. The support rod 6 is installed in the mounting hole of the side rail 3 through the matching bolts and knobs to achieve the height position adjustment and fixation of the eccentric wheel mechanism 5.

[0031] The eccentric wheel mechanisms 5 on the left and right side rails 3 are arranged in pairs relative to each other. A rocking plate 11 is provided above the eccentric wheel mechanisms 5. The rocking plate 11 is supported and rocked by all the eccentric wheel mechanisms 5. A screen structure for screening is provided on the surface of the rocking plate 11.

[0032] The two ends of the rocking plate 11 are respectively provided with convex handles on the left and right sides, and the convex handles correspond to the vertical long holes provided on the four frames 1 .

[0033] When the rocking plate 11 rocks, the convex handle of the rocking plate 11 moves up and down in the corresponding vertical long hole on the frame 1, forming a buffer force, which facilitates the rocking plate 11 to rock up and down without falling off.

[0034] A transmission sprocket mechanism 13 is provided inside the left and right side rails 3. The transmission sprocket mechanism 13 includes drive sprockets 14 at each end and a chain 15 wound around the drive sprockets 14. The drive sprockets 14 at one end of the side rail 3 are coaxially connected to each other via a coupling 16. One of the drive sprockets 14 serves as the active sprocket and is driven by a lightweight drive motor 17 mounted on the corresponding side rail 3. The lightweight drive motor 17 drives the main sprocket and the other drive sprockets 14 to rotate together, causing the transmission sprocket mechanism 13 to rotate the sprockets. The lightweight drive motor 17 can be a low-power motor mechanism, reducing energy consumption while achieving functional effects.

[0035] The eccentric wheel mechanisms 5 on the left and right side rails 3 are correspondingly located between the upper and lower chains 15 of the transmission sprocket mechanism 13, and the protruding member 10 of the eccentric wheel mechanism 5 cooperates with the chain 15 of the transmission sprocket mechanism 13, so that the transmission sprocket mechanism 13 drives the rotating wheel 8 of the eccentric wheel mechanism 5 to rotate, and then drives the eccentric support wheel 9 to rotate, so that the shaking plate 11 on the eccentric wheel mechanism 5 shakes.

[0036] An inclined receiving plate 12 is installed just below the shaking plate 11 on the frame 1. The receiving plate 12 is mounted on the four columns 2 of the frame 1 and cooperates with the shaking plate 11 to transport and discharge the fine sand minerals screened by the shaking plate 11.

[0037] A bottom base plate is provided at the bottom of the frame 1 , and the bottom of the frame 1 and the bottom base plate are connected in a sliding manner by means of guide rails, and lubricating oil is used to enable the frame 1 to move silently on the guide rails of the bottom base plate.

[0038] A vibration motor 18 is mounted on the bottom substrate at one end of the frame 1. A vibration connector 19 is attached to the vibration motor 18. The vibration connector 19 is connected to the frame 1 and transmits the vibration force of the vibration motor 18 to the main body of the frame 1. A compression spring 20 and a support plate 21 are mounted on the bottom substrate at the other end of the frame 1. The support plate 21 is vertically mounted on the bottom substrate. One end of the compression spring 20 is mounted on the support plate 21, while the other end rests against the bottom side of the frame 1.

[0039] When the frame 1 vibrates under the vibration drive of the vibration motor 18, the compression spring 20 acts as a buffer, thereby causing the entire frame 1 to vibrate horizontally. The compression spring 20 and the abutment plate 21 are arranged in pairs, with one set of compression spring 20 and abutment plate 21 being provided on the left and right sides of one end of the frame 1.

[0040] During implementation of the present invention, in the initial state, a rocking plate 11 is provided above the eccentric mechanism 5. The rocking plate 11 is supported and rocked by all the eccentric mechanisms 5. A screening mesh structure is provided on the surface of the rocking plate 11. Protruding handles are provided on the left and right ends of the rocking plate 11. The protruding handles correspond to the vertical elongated holes provided on the four frames 1. An inclined receiving plate 12 is installed directly below the rocking plate 11 on the frame 1. The receiving plate 12 is mounted on the four uprights 2 of the frame 1 and corresponds to the rocking plate 11, ready for operation.

[0041] After the machine is turned on, the lightweight drive motor 17 drives the main sprocket and other drive sprockets 14 to rotate together, causing the transmission sprocket mechanism 13 to rotate. The eccentric wheel mechanism 5 on the left and right side rails 3 is located between the upper and lower chains 15 of the transmission sprocket mechanism 13. The protrusions 10 of the eccentric wheel mechanism 5 cooperate with the chains 15 of the transmission sprocket mechanism 13, causing the transmission sprocket mechanism 13 to rotate the rotating wheel 8 of the eccentric wheel mechanism 5, which in turn drives the eccentric support wheel 9 to rotate, causing the rocking plate 11 on the eccentric wheel mechanism 5 to rock. The bottom of the frame 1 is connected to the bottom base plate using a guide rail sliding fit, and lubricating oil is used to ensure that the frame 1 moves silently on the guide rails of the bottom base plate.

[0042] When the vibration motor 18 is activated, the frame 1 shakes under the vibration drive of the vibration motor 18. The compression spring 20 acts as a buffer, thereby causing the entire frame 1 to vibrate horizontally. When the rocking plate 11 shakes, the protruding handle of the rocking plate 11 moves up and down within the corresponding vertical slot on the frame 1, generating a buffering force, which facilitates the rocking plate 11 to shake up and down without disengaging.

[0043] The mineral to be screened is placed upside down on the shaking plate 11, which screens the mineral under the dual effects of shaking and vibration. Then, the receiving plate 12 arranged just below the shaking plate 11 on the frame 1 cooperates with the shaking plate 11 to transfer and discharge the fine sand minerals screened by the shaking plate 11.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
