Description

Technical Field

[0001] The present invention relates to the technical field of slurry transportation, and in particular to a multi-position distribution slurry intelligent feeding device. Background Art

[0002] In order to improve process efficiency, reduce waiting time for intermediate transfers, and avoid affecting operational stability due to excessive load on a single diversion pipeline, a multi-position slurry distribution device is currently often used to transport the slurry to different equipment or work sections at the same time.

[0003] The multi-position slurry distribution device rotates the distribution pipes mounted on the central inner cylinder, sequentially directing the slurry into multiple storage chambers separated by partitions within the outer cylinder. Each chamber corresponds to a corresponding diversion pipe, which transports the slurry to the corresponding downstream equipment. The slurry flow rate required by different equipment or work sections varies. However, in existing multi-position slurry distribution devices, the outlet flow rate of the distribution pipes on the inner cylinder is fixed and cannot be automatically adjusted in real time based on the accumulation of slurry in each storage chamber. This can easily lead to excessive slurry accumulation in the chamber corresponding to the diversion pipe with a smaller flow demand, causing overflow, resulting in resource waste and environmental pollution. Summary of the Invention

A circular floating plate is provided in the silo, and the four sides of the circular floating plate are tightly attached to the four sides of the inner wall of the silo. A connecting rod is connected to the side of the top of the circular floating plate away from the inner cylinder, and an arc-shaped push plate is connected to the connecting rod. The push plate can move up to contact the sliding rod, and both ends of the push plate are designed with inclined surfaces.

[0006] Preferably, a concentration measuring mechanism is provided on the outer cylinder, and the concentration measuring mechanism includes a fixed rod connected to the outer wall of the outer cylinder, an L-shaped injection pipe is connected to the fixed rod, the discharge end of the L-shaped injection pipe extends into the inner cylinder, and a blocking plate is slidingly provided on one side of the injection pipe near its feed end for blocking the injection pipe, a driving member for driving the blocking plate to rise and fall is installed on the outside of the injection pipe, and an ultrasonic slurry concentration meter is installed on the side of the injection pipe near its feed end.

[0007] Preferably, a flow meter is installed on the diversion pipe.

[0008] Preferably, a stirring mechanism is provided in the inner cylinder, and the stirring mechanism includes a baffle connected to the inner cylinder, the baffle is located on the lower side of the distribution pipe, a rotating shaft is provided on the baffle, and stirring plates located on the upper side of the baffle are connected to the rotating shaft at intervals along the circumferential direction, and a driving motor for driving the rotating shaft to rotate is installed at the inner bottom of the inner cylinder.

[0009] Preferably, the driving mechanism includes an annular slide rail mounted on the frame, an annular slider is slidably provided on the annular slide rail, the annular slider is fixedly connected to the bottom of the inner cylinder, and a reduction motor for driving the inner cylinder to rotate is mounted on the frame.

[0011] Preferably, discharge holes are spaced apart on the circumferential side wall of the lower portion of the injection tube.

[0012] Preferably, a contact wheel for reducing friction is provided on the end of the slide bar away from the blocking block.

[0013] Preferably, the stirring plate is wavy in shape.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The flow of the diversion pipe can be adjusted by the solenoid valve to achieve intelligent and automatic flow adjustment to adapt to the slurry flow required by different equipment or work sections, with strong flexibility; through the sealing mechanism composed of a slide bar, a blocking block, a return float, a connecting rod and a push plate, the flow of the diversion pipe can be automatically adjusted in real time according to the accumulation of slurry in each silo, so as to avoid continuously injecting ore into the silo corresponding to the diversion pipe with a smaller flow demand, thereby avoiding excessive slurry accumulation in the silo corresponding to the diversion pipe with a smaller flow demand, preventing overflow, avoiding resource waste and environmental pollution, and being able to continuously inject ore into the silo corresponding to the diversion pipe with a larger flow demand, ensuring that the amount of slurry injected into each silo can be reasonably distributed according to actual needs, so as to ensure a stable slurry supply for subsequent operations or work sections.

DETAILED DESCRIPTION

[0026] See also Figures 1-6 A multi-position distribution slurry intelligent feeding device includes a frame 1, which includes a chassis 01, a support rod 02 and a support plate 03. The middle of the top of the chassis 01 is connected to the support rod 02, and the upper part of the support rod 02 is connected to the support plate 03. An inner cylinder 2 is provided above the support rod 02, and a driving mechanism for driving the inner cylinder 2 to rotate is provided on the top of the support rod 02. The driving mechanism includes an annular slide rail 51 installed on the top of the support rod 02, and an annular slider 52 is slidably provided on the annular slide rail 51. The annular slider 52 is fixedly connected to the bottom of the inner cylinder 2, and a reduction motor 5 is installed on the top of the support rod 02. 3. The reduction motor 53 is located on the inner side of the annular slide rail 51. The output shaft of the reduction motor 53 is connected to the bottom of the inner cylinder 2 to drive the inner cylinder 2 to rotate. Six L-shaped material distribution pipes 21 are evenly spaced along the circumference of the inner cylinder 2. An outer cylinder 3 is provided on the outside of the inner cylinder 2. The top and bottom of the outer cylinder 3 are both open-type designs. Eight arc-shaped silos 4 are connected to the inner wall of the outer cylinder 3 along the circumference. The silos 4 are fixedly connected to the support plate 03. The silos 4 are designed to be larger at the top and smaller at the bottom. The adjacent two silos 4 are close together. The bottom of the silo 4 is connected to a diversion pipe 41. The diversion pipe 4 1 passes through the support plate 03, a solenoid valve 42 is installed on the diversion pipe 41, and a blocking mechanism is provided between the distribution pipe 21 and the silo 4. The blocking mechanism includes a slide rod 61 slidably connected to the distribution pipe 21 away from the side of the inner cylinder 2, and a block 62 for blocking the distribution pipe 21 is connected to the slide rod 61. The block 62 is located in the horizontal section of the L-shaped distribution pipe 21. A return float 63 is provided in the silo 4. The four sides of the return float 63 are in close contact with the four sides of the inner wall of the silo 4, ensuring that the return float 63 can float up and down with the change of the slurry amount in the silo 4, thereby avoiding the return float. The circular floating plate 63 is offset or tilted in the silo 4. Two connecting rods 64 are symmetrically connected to the side of the top of the circular floating plate 63 away from the inner tube 2. An arc-shaped push plate 65 is connected between the tops of the two connecting rods 64. The push plate 65 moves upward to contact the slide bar 61. Both ends of the push plate 65 are designed with inclined surfaces. A contact wheel 66 is rotatably provided on the end of the slide bar 61 away from the block 62. The contact wheel 66 can reduce the friction between the slide bar 61 and the push plate 65, reduce the wear on the slide bar 61 and the push plate 65, and extend the service life of the slide bar 61 and the push plate 65.

[0027] First, connect each diversion pipe 41 to each corresponding device through a pipeline, then inject the slurry into the inner tube 2 through the external injection pipe. The slurry in the inner tube 2 is discharged into the silo 4 through the distribution pipe 21. The slurry in the silo 4 is transported to the corresponding equipment through the diversion pipe 41 and the pipeline. Control the reduction motor 53 to drive the inner tube 2 to drive the distribution pipe 21 to rotate, so that the mineral material can be evenly distributed to each silo 4. The flow of the diversion pipe 41 can be adjusted by the solenoid valve 42, realizing intelligent and automated flow adjustment to adapt to the slurry flow required by different equipment or work sections, with strong flexibility. As the liquid level of the slurry in the silo 4 corresponding to the diversion pipe 41 with smaller flow demand rises, the circular float 63 in the silo 4 corresponding to the diversion pipe 41 with smaller flow demand is pushed upward, thereby driving the push plate 65 upward through the connecting rod 64. When the distribution pipe 21 drives its upper slide rod 61 to rotate until it contacts the inclined surface on the upward push plate 65, the slide rod 61 is squeezed by the inclined surface on the push plate 65, so that the slide rod 61 pushes the block 62 to move toward the direction close to the inner tube 2, blocking the feed end of the distribution pipe 21, so as to avoid continuous injection of mineral materials into the silo 4 corresponding to the diversion pipe 41 with a smaller flow demand, to avoid excessive accumulation of mineral slurry in the silo 4 corresponding to the diversion pipe 41 with a smaller flow demand, to prevent overflow, and to avoid waste of resources and environmental pollution. When the slide bar 61 rotates to disengage from the upward push plate 65, the slurry in the diverter pipe 41 pushes the block 62 to move away from the inner tube 2, releasing the blockage on the feed end of the distribution pipe 21, thereby continuously injecting the mineral material into the corresponding silo 4 of the diverter pipe 41 with a larger flow demand, ensuring that the amount of slurry injected into each silo 4 can be reasonably distributed according to actual needs, thereby achieving the effect of automatically adjusting the flow of the distribution pipe 21 in real time according to the accumulation of slurry in each silo 4, so as to ensure a stable supply of slurry for subsequent operations or work sections.

[0028] See also Figure 1 and Figure 7The outer cylinder 3 is provided with a concentration measuring mechanism, which includes a fixed rod 81 connected to the outer wall of the outer cylinder 3, an L-shaped injection tube 82 connected to the top of the fixed rod 81, the discharge end of the L-shaped injection tube 82 extends into the inner cylinder 2, and a blocking plate 85 is slidably provided on one side of the injection tube 82 near its feed end for blocking the injection tube 82. A driving member for driving the blocking plate 85 to rise and fall is installed on the outside of the injection tube 82, and the driving member includes an electric push rod 83 installed on the top of the injection tube 82. The electric push rod 83 An L-shaped rod 84 is connected to the telescopic rod, and the L-shaped rod 84 is connected to the blocking plate 85. An ultrasonic slurry concentration meter 86 is installed on the side of the injection pipe 82 near its feed end. Discharge holes 87 are spaced apart on the circumferential side wall of the lower part of the injection pipe 82 to increase the slurry discharge area, improve the discharge uniformity, and make the slurry more evenly discharged into the inner tube 2, realizing multi-point uniform distribution, effectively improving the flow distribution state of the slurry in the inner tube 2, thereby providing a more stable and reliable basic condition for subsequent diversion and regulation.

[0029] The slurry is injected into the inner tube 2 through the injection pipe 82. The concentration of the slurry injected into the injection pipe 82 can be detected in real time by the ultrasonic slurry concentration meter 86. The ultrasonic slurry concentration meter 86 is a prior art and will not be described in detail here. When the ultrasonic slurry concentration meter 86 detects that the slurry concentration is higher or lower than the preset value, the ultrasonic slurry concentration meter 86 sends a signal to the controller. The controller is not shown in the figure. The controller is a prior art and will not be described in detail here. After receiving the signal, the controller controls the electric push rod 83 to drive the L-shaped rod 84 to drive the blocking plate 85 to move down to block the feed end of the injection pipe 82, thereby preventing slurry with too high or too low concentration from entering the subsequent processing steps, ensuring that the subsequent operation or work section obtains the required slurry concentration.

[0030] See also Figure 1 A flow meter 43 is installed on the shunt pipe 41 and is located on the lower side of the solenoid valve 42. The flow meter 43 can measure the instantaneous flow rate (i.e., the flow rate per unit time) and the cumulative flow rate (i.e., the total flow rate over a period of time) of the slurry flowing through the shunt pipe 41, thereby providing accurate slurry flow data. By electrically connecting the flow meter 43 to the background terminal, the flow data can be transmitted to the background terminal in real time for analysis and display, so that operators can monitor the production process and adjust process parameters in a timely manner.

[0031] See also Figure 8, a stirring mechanism is provided in the inner cylinder 2, and the stirring mechanism includes a baffle 91 connected to the inner cylinder 2, the baffle 91 is located at the lower side of the distribution pipe 21, and a rotating shaft 92 is rotatably provided on the baffle 91. Six stirring plates 93 are connected to the rotating shaft 92 at even intervals along the circumference, and the stirring plates 93 are located on the upper side of the baffle 91. A driving motor 94 is installed at the bottom of the inner side of the inner cylinder 2, and the output shaft of the driving motor 94 is connected to the rotating shaft 92 to drive the rotating shaft 92 to drive the stirring plates 93 to rotate and stir the slurry. The shape of the stirring plates 93 is wavy, and the wavy design increases the contact area between the stirring plates 93 and the slurry. Compared with the flat stirring plates, it can more effectively disrupt the flow state of the slurry, generate more turbulence and eddy currents, thereby improving the stirring effect, and more effectively keeping the slurry in a suspended state, reducing the sedimentation of particulate matter.

[0032] The drive motor 94 is controlled to operate, driving the rotating shaft 92 to rotate the stirring plate 93, stirring the slurry in the inner drum 2. This keeps the slurry in suspension, reduces particulate matter settling, helps maintain a uniform distribution of slurry components, prevents areas of excessively high or low concentration, and promotes consistency in subsequent processing steps. The baffle 91 effectively blocks the slurry, preventing it from corroding the drive motor 94, thereby protecting the drive motor 94 from damage.
