Description

Technical Field

[0001] This utility model relates to the field of shaking table technology, and more specifically, to a shaking table with adjustable baffles. Background Technology

[0002] Traditional shaking tables have a fixed receiving trough on the discharge side of the table surface, with fixed partitions dividing the collection areas for concentrate and tailings. This fixed structure has significant drawbacks: when the grade of the raw ore (i.e., the content of valuable elements) fluctuates, the width and position of the mineral bands on the table surface will change accordingly. If the grade of the raw ore increases, the concentrate band widens, and the fixed concentrate receiving area cannot cover all high-grade minerals, causing some qualified concentrate to flow into the tailings, resulting in resource waste and economic losses. Conversely, if the grade of the raw ore decreases, the concentrate band narrows, and the fixed receiving area will receive some substandard materials, resulting in unqualified concentrate that needs to be returned for reprocessing or downgraded, increasing production costs and process complexity. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shaker with an adjustable baffle to solve the above-mentioned shortcomings.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model discloses a shaking table with adjustable baffles, including a bed surface, a frame, a feed trough, a water trough, and a transmission mechanism. The bed surface is provided on the frame, and a transmission mechanism is provided at one end of the frame. The transmission mechanism is connected to the bed surface through a connecting rod. A feed trough and a water trough are provided on one side of the bed surface. A movable baffle system is provided on the product discharge side of the bed surface and is fixed on the frame.

[0006] Preferably, the movable baffle system includes a mounting frame, a lead screw assembly, a baffle bracket, and a baffle body. The mounting frame is fixedly connected to the frame. The lead screw assembly is mounted on the mounting frame and includes a lead screw body and a micro motor control box for driving its rotation. The baffle bracket is sleeved on the lead screw body, and the baffle body is mounted on the baffle bracket.

[0007] Preferably, the baffle bracket has a sliding hole that engages with the mounting bracket.

[0008] Preferably, the lower end of the baffle bracket is provided with a sliding groove, a slider is movably connected in the sliding groove, a first screw passes through the sliding groove, and the first screw meshes with the slider.

[0009] Preferably, an adjusting block is provided at the lower end of the baffle body, and the upper side of the baffle bracket and the side adjacent to the slide groove are open structures, with the adjusting block placed in the open and slidingly engaged with the inner wall of the baffle bracket.

[0010] Preferably, a second screw is movably connected to the slider, and a threaded hole matching the second screw is provided on the adjusting block.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0012] This invention uses a micro-motor control box to drive a lead screw, which can precisely control the lateral position of the baffle body, ensuring that qualified concentrate products are always collected even when the raw ore grade fluctuates. It also maximizes the recovery of valuable minerals, effectively improving concentrate yield and metal recovery rate. This invention can be linked with online grade analyzers and other detection equipment via a communication interface to form a closed-loop control system. The system can automatically adjust the baffle position based on real-time concentrate grade data, achieving fully intelligent production, reducing manual intervention and operational lag, and keeping production at its optimal state. The baffle body can not only move laterally, but its longitudinal distance from the edge of the bed surface can be adjusted via the first screw, and its height above the ground via the second screw. This three-dimensional adjustment capability allows the baffle to perfectly adapt to the separation needs under different mineral properties, feed concentrations, and water volumes, making it highly versatile. The baffle support is connected to the mounting frame via sliding holes, forming a stable guiding structure that ensures the stability of the baffle during movement and prevents jamming and shaking.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figures 1-4 This utility model discloses a shaking table with adjustable baffles, including a bed surface 1, a frame 2, a feed trough 3, a water trough 4, and a transmission mechanism 5. The bed surface 1 is mounted on the frame 2, and the transmission mechanism 5 is mounted on one end of the frame 2. The transmission mechanism 5 is connected to the bed surface 1 via a connecting rod. The feed trough 3 and the water trough 4 are mounted on one side of the bed surface 1. The specific structure and working principle of the bed surface 1, the frame 2, the feed trough 3, the water trough 4, and the transmission mechanism 5 are similar to those disclosed in Chinese Patent No. CN220737935U, which discloses a new type of shaking table. It should be noted that a movable baffle system 6 is provided on the product discharge side of the bed surface 1, and the movable baffle system 6 is fixed on the frame 2.

[0021] Specifically, the movable baffle system 6 includes a mounting frame 61, a lead screw assembly 62, a baffle bracket 63, and a baffle body 64. The two ends of the mounting frame 61 are connected to the frame 2 by bolts. The mounting frame 61 protrudes towards the product discharge side of the bed surface 1, and the lead screw assembly 62 is provided on the recessed surface of the mounting frame 61. The lead screw assembly 62 includes a lead screw body 621 movably connected to the end of the mounting frame 61 through a bearing, and a micro motor control box 622 fixed to one end of the mounting frame 61. The micro motor control box 622 drives the lead screw body 621 to rotate. The baffle bracket 63 is sleeved on the lead screw body 621, and the baffle body 64 is installed on the baffle bracket 63.

[0022] It is important to know that the micro motor control box 622 is equipped with:

[0023] Miniature motors: As a power source, stepper motors or servo motors are usually used;

[0024] Reducer: Connected to the motor output shaft;

[0025] Coupling: Used to connect the output shaft of the reducer to the input end of the lead screw body 621, transmit torque, and compensate for minor concentricity errors;

[0026] Motor driver: Receives low-power pulse signals from the control board and converts them into powerful current and voltage to drive the motor to rotate precisely step by step or at a specific speed;

[0027] Main control board: A circuit board that integrates a microprocessor MCU or a miniature programmable logic controller (PLC), which is responsible for receiving external instructions, processing logic, and sending control signals to the motor driver;

[0028] Power module: Provides a stable DC power supply for all electronic components such as motors, main control boards, and drivers;

[0029] Communication interface: Used to receive external control signals. It can be a simple I / O interface to receive switch signals from buttons; or it can be a communication bus interface, such as RS485, CAN or Ethernet, to receive digital instructions from a host computer or automation system, and connect to the online quality analyzer system to achieve advanced automation control.

[0030] More specifically, the baffle bracket 63 has a sliding hole 631 that engages with the mounting bracket 61. When the lead screw body 621 drives the baffle bracket 63 to move, the sliding hole 631 moves along the mounting bracket 61, improving the stability of the baffle bracket 63. The lower end of the baffle bracket 63 has a sliding groove 632, in which a slider 633 is movably connected. A first screw 634 passes through the sliding groove 632, passing through the slider 633 and engaging with it. Rotating the first screw 634 can control the slider 633 to move along the sliding groove 632, adjusting the distance between the baffle body 64 connected to the slider 633 and the edge of the bed surface 1.

[0031] Furthermore, a second screw 635 is movably connected to the slider 633. The upper end of the second screw 635 engages with the baffle body 64. An adjusting block 641 is provided on one side of the lower end of the baffle body 64. The adjusting block 641 has a threaded hole that matches the second screw 635. The upper side of the baffle bracket 63 and the side adjacent to the slide groove 632 are both open structures. The width of the adjusting block 641 is the same as the width of the inner wall of the open baffle bracket 63. The adjusting block 641 is clamped by the baffle bracket 63. By rotating the second screw 635, the adjusting block 641 can be pushed up and down to adjust the height of the baffle body 64.

[0032] Working process: Based on the basic characteristics of the minerals to be sorted, the baffle is initially positioned. The operator can manually rotate the first screw 634 to drive the slider 633 to move within the groove 632, thereby adjusting the initial distance of the baffle body 64 from the edge of the bed surface 1 in the longitudinal direction. Rotating the second screw 635 pushes the adjusting block 641 to move the baffle body 64 up and down, adjusting its lower edge to the optimal height with a small gap of 0.2-0.5mm between it and the surface of the bed surface 1. During the normal sorting process of the shaking table, an online grade analyzer (not shown in the figure) monitors the concentrate stream in real time. When the analyzer detects that the concentrate grade (such as effective sulfur content) is higher than the set target value (such as 33% > 30%), it will send a signal through the communication interface. The data is sent to the main control board inside the micro-motor control box 622. After calculation, the main control board instructs the motor driver to drive the micro-motor to rotate. Through the reducer and coupling, the power is transmitted to the lead screw body 621 to rotate, driving the baffle bracket 63 to move towards the tailings trough, thereby expanding the concentrate collection area and recovering the enriched minerals that would otherwise be lost, increasing the total output of qualified concentrate. Conversely, when the online grade analyzer detects that the concentrate grade is close to or below the qualified line (e.g., 29% < 30%), the system will control the micro-motor to rotate in the opposite direction, driving the baffle bracket 63 to move towards the concentrate trough, reducing the concentrate collection area, and excluding unqualified low-grade mineral particles from the concentrate product, thereby ensuring that the grade of the produced concentrate is consistently up to standard.
