Description

Technical Field

[0001] The invention belongs to the technical field of mine paste filling equipment, and in particular relates to an anti-clogging bucket cone for mine paste filling powder. Background Art

[0002] Conical hoppers with cones are often used for metering and batching of powder for filling of mining paste. Due to the wide variety of filling powders and the fact that fluidity is greatly affected by changes in material level and moisture content, the powder in the cone of the hopper has self-weight compression arch bridges and poor discharge. Traditional processes usually use compressed air injection and external vibrators to break the arches and assist flow. Compressed air injection can easily cause dust and airflow to suddenly gush out of the upstream and downstream interfaces of the hopper, causing environmental pollution problems. The high-frequency vibration breaking effect of the external vibrator is greatly affected by the thickness of the wall material, resulting in high energy consumption, fatigue damage to the hopper wall material, easy damage to the weighing sensor, excessive residual powder in the hopper, and noise pollution.

[0014] The flow-aiding method based on the above-mentioned mining paste filling powder anti-clogging bucket cone includes the following steps: (1) Make the anti-clogging bucket cone of the mining paste filling powder in the initial state: the length direction of the rotary rake arm is parallel to the length direction of the rectangular flange plane; the horizontal straight line through the center point of the C pin is below the horizontal straight line through the center point of the fixed transmission shaft, the acute angle between the B pin, the C pin and the fixed transmission shaft is 45°, and the piston rod of the drive cylinder is fully retracted; (2) The piston rod of the driving cylinder is extended, and the end of the piston rod pushes the torque increasing connecting rod through the E pin shaft to drive the fixed transmission shaft to rotate 45 degrees. The fixed transmission shaft drives the rotary plate to rotate synchronously, and the rotary plate drives the C pin shaft to rotate synchronously. The C pin shaft drives the range extending connecting rod to move. The range extending connecting rod drives the range extending ear seat and the rotary rake arm to rotate around the A pin shaft through the B pin shaft, and the rotary rake arm swings outward to the maximum angle; (3) The piston rod of the driving cylinder is extended to the maximum extension length. The end of the piston rod pushes the torque increasing connecting rod through the E pin shaft to drive the fixed transmission shaft to continue to rotate 45° on the basis of step (2). The fixed transmission shaft drives the rotating plate to rotate synchronously. The rotating plate drives the C pin shaft to rotate synchronously. The C pin shaft drives the range extending connecting rod to move. The range extending connecting rod drives the range extending ear seat and the rotary rake arm to rotate in the opposite direction around the A pin shaft through the B pin shaft. The rotary rake arm swings in the opposite direction until it is parallel to the rectangular flange plane. (4) The driving cylinder retracts the piston rod. The end of the piston rod pushes the torque increasing connecting rod through the E pin shaft to drive the fixed transmission shaft to rotate 45° in the opposite direction based on step (3). The fixed transmission shaft drives the rotary plate to rotate in the opposite direction synchronously. The fixed rotary plate drives the C pin shaft to rotate in the opposite direction synchronously. The C pin shaft drives the range extending connecting rod to move. The range extending connecting rod drives the range extending ear seat and the rotary rake arm to rotate around the A pin shaft through the B pin shaft. The rotary rake arm swings outward to the maximum angle. (5) The driving cylinder completely retracts the piston rod. The end of the piston rod pushes the torque increasing connecting rod through the E pin shaft to drive the fixed transmission shaft to rotate 45° in the opposite direction based on step (4). The fixed transmission shaft drives the rotating plate to rotate in the opposite direction synchronously. The rotating plate drives the C pin shaft to rotate in the opposite direction synchronously. The C pin shaft drives the range extending connecting rod to move. The range extending connecting rod drives the range extending ear seat and the rotating rake arm to rotate around the A pin shaft through the B pin shaft. The rotating rake arm swings in the opposite direction until it is parallel to the rectangular flange plane and returns to the initial state of step (1). (6) Repeat steps (1) to (5), and the rotary rake wall swings repeatedly to destroy the material bridge arch, thereby achieving continuous flow assistance.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. An isolation plate is provided on the upper part of the bucket cone, which divides the bucket cone into two sections, the upper section is divided by the isolation plate to form four identical areas with vertical side walls, eliminating the condition for high-position powder in the upper section of the bucket cone to form a bridge arch at the axis; the bucket cone wall is the arch foot foundation section of the material arch bridge, and the rotary rake wall is set along the length direction of the bucket cone wall generatrix, with a length covering the upper and lower ends. By rotating and swinging into the bucket cone, the powder bridge arch foundation is destroyed. It has a dual flow-aiding function and is highly adaptable to material changes.

[0016] 2. The rotation center of the rotary rake arm is located at the upper end, and the swing displacement of the lower end is greater than that of the upper end. While destroying the compacted material at the lower end, it further activates the material near the upper end, which is conducive to the continuous and stable flow of bucket cone powder to the lower outlet.

[0017] 3. The rotary harrow wall adopts a rectangular long thin plate structure. The thin plate plane is parallel to the direction of the rotary harrow wall, which is conducive to cutting the powder bridge arch and has low energy consumption.

[0018] 4. It is equipped with a range-extending ear seat and a range-extending connecting rod, which can be configured to adjust the swing displacement of the lower end of the rotary rake arm 2 according to the material characteristics and the size of the inclined wall of the bin, and has strong adaptability to the bin structure.

[0019] 5. A torsion-increasing connecting rod is provided, which can increase the torque and reduce the thrust of the driving cylinder by lengthening the torsion-increasing connecting rod, and has low energy consumption.

[0020] 6. There is a rotating disc. The gap between the rotating disc and the disc shell remains unchanged during the rotation process, which prevents the incremental material from entering the gap space and causing jamming, and has high reliability.

[0021] 7. The rotary rake arm is equipped with rake teeth, which expands the contact range with the material and has a good arch-breaking and flow-aiding effect.

[0022] 8. The stroke of the drive cylinder can be adjusted to change the rotation angle of the turntable. One movement of the drive cylinder can achieve the adjustment function of swinging the rotary rake arm once or twice.

[0023] 9. The drive cylinder can adopt a telescopic drive cylinder to drive the transmission shaft together with the torsion-increasing connecting rod, or a rotary drive cylinder can be used to directly drive the transmission shaft, which is convenient for selection according to the material load characteristics to achieve low-consumption drive.

[0024] In conclusion, the present invention effectively solves the problems of poor discharge and poor flow-aiding effect of the existing powder hopper cone. BRIEF DESCRIPTION OF THE DRAWINGS
