Description

Technical Field

[0001] The invention relates to the technical field of raw coal transportation, and in particular to an anti-blocking divided-bin type raw coal bunker. Background Art

[0002] In the production process of the power, building materials, energy, chemical and other industries, different types of coal need to be mixed and then transported to the coal feeder through the coal bunker. The existing coal bunker is usually composed of a square upper part and a funnel-shaped lower part. The conventional feeding device adopts equal-diameter screws or gravity coal dropping. The constant cross-section of the equal-diameter screw cannot gather the coal flow. The coal is dispersed due to its own weight during transportation, forming local gaps ("bridge phenomenon"), and the loose coal flow is layered under the action of gravity. The friction between the coal blocks increases, which hinders the overall flow and eventually causes blockage. The blocked coal is in static contact with the bunker wall for a long time, and the coal The deadweight of the block and the pressure of the upper coal flow cause plastic deformation of the contact surface, so that the coal powder is embedded in the micropores on the surface of the silo wall to form a physical adsorption layer, which greatly improves the adhesion and makes the blocked coal more easily adhere to the silo wall. In the prior art, a vibration device is usually installed on the silo wall to prevent the coal from adhering to the silo wall by driving the silo wall to vibrate. Since the vibration energy of the vibration device will continue to decay in the silo, the vibration energy is only effective in the area close to the source of the earthquake. The silo wall far away from the source of the earthquake will still form an adhesion layer due to the stagnation of the coal flow, and it is impossible to effectively maintain the smooth flow inside the coal silo for a long time. If multiple sets of seismic sources are used to work together, the cost will be further increased. Summary of the invention

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] Example 1 See also Figure 1-Figure 9As shown, the purpose of this embodiment is to provide an anti-blocking divided-bin raw coal bin, including a distribution port 5, a square bin 11 is fixedly connected below the distribution port 5, and a funnel bin 12 is connected below the square bin 11. Different types of coal are put into the distribution port 5 and fall through the bottom of the funnel bin 12. A feeding device 2 is arranged inside the square bin 11. The feeding device 2 rotates and pushes the coal to move to the funnel bin 12 below the square bin 11. The rigid support structure of the square bin 11 and the funnel bin 12 reduces the risk of lateral collapse by dispersing the coal flow pressure. Two isolation devices 3 are symmetrically arranged on the two side walls of the funnel bin 12. The isolation devices 3 isolate the coal from the inner wall of the funnel bin 12. The coal falls downward along the isolation devices 3. The isolation devices 3 block the direct contact between the coal and the bin wall, thereby reducing the probability of adhesion caused by friction. When working, the isolation devices 3 tear the compacted coal blocks attached to the side walls of the isolation devices 3, and destroy the coal by shear force. The coal blocks are adhered to the feed device 2 to prevent the coal blocks from accumulating and clogging. The coal blocks torn by the isolating device 3 fall from the bottom of the hopper bin 12. A transmission device 4 is arranged on one side of the feeding device 2. The isolating device 3 is driven by the transmission device 4 to remove the coal blocks attached to the isolating device 3, and the coordinated control of the feeding and anti-blocking actions is realized at the same time. The bottom of the rotating feeding device 2 continues to push the coal blocks dropped from the isolating device 3 to move downward, and its continuous push ensures that the coal falls continuously without stagnation. A plurality of scrapers 15 are fixedly installed on the side of the isolating device 3 away from the side wall of the hopper bin 12. The scraper 15 is arranged to be thick in the middle and thin on both sides. Its parabolic cross-section efficiently removes the residual coal blocks on the surface of the isolation plate through the scraping action, thereby reducing the formation of secondary compaction. When the isolating device 3 removes the compacted coal blocks, it scrapes against the scraper 15. The scraper 15 removes the coal attached to the isolating device 3, and its periodic cleaning mechanism prevents the coal blocks from being attached to the equipment for a long time and affecting the operation of the equipment.

[0021] The feeding device 2 includes a protective shell 22 arranged at the top of the square bin 11. The outer wall of the protective shell 22 is fixedly installed in the inner wall of the square bin 11 through a plurality of fixing rods 23. The protective shell 22 wraps the internal mechanical structure to prevent coal dust from invading. The fixing rods 23 enhance the overall connection stability and reduce the impact of vibration on the bin body. A motor 24 is fixedly installed inside the fixing rod 23. The rotating shaft of the motor 24 passes through the bottom of the protective shell 22 and is fixedly connected to a screw 21. The motor 24 provides a controllable power source. The screw 21 is set to a cone with a thick top and a thin bottom. The conical screw 21 passes through the bottom of the protective shell 22. The coal is gathered downward through the tapering cross-section to reduce coal accumulation caused by uneven distribution of coal flow in the bin. Spiral blades are arranged on the side walls of the screw 21. The motor 24 drives the screw 21 to rotate through the rotating shaft. The rotating screw 21 stirs the coal through the spiral blades to make the coal move downward and enter the hopper bin 12. The spiral blades force the coal to fall to avoid stagnation and blockage caused by insufficient weight of the coal blocks. A supporting rod 14 is fixedly installed at the bottom of the hopper bin 12, and the bottom of the screw 21 is rotatably installed on the supporting rod 14 to maintain the stability of the axis and prevent the decrease in transportation efficiency caused by yaw.

[0022] The isolation device 3 includes a plurality of first isolation plates 38 and second isolation plates 39 slidingly arranged on the inner wall of the funnel bin 12. The plurality of first isolation plates 38 and second isolation plates 39 are staggered. The first isolation plates 38 and the second isolation plates 39 generate shear force through periodic sliding, tearing the compacted coal blocks attached to the surface, blocking the direct contact between the coal and the bin wall, and reducing adhesion caused by friction. The plurality of first isolation plates 38 and second isolation plates 39 isolate the coal and the inner wall of the funnel bin 12 to prevent the coal from agglomerating on the bin wall. When the coal is agglomerated into coal blocks on the first isolation plates 38 and the second isolation plates 39, the staggered sliding isolation plates exert a bidirectional pulling force on the coal blocks through relative displacement, destroying the internal structure of the coal blocks and breaking them into pieces, thereby preventing large pieces of coal from blocking the falling channel; the torn coal blocks fall to the bottom of the funnel bin 12, ensuring the stability of the anti-blocking effect during long-term operation.

[0023] The first isolation plate 38 and the second isolation plate 39 are arranged between the scraper 15 and the inner wall of the funnel bin 12. The first isolation plate 38 and the second isolation plate 39 are in close contact with the scraper 15. The first isolation plate 38 and the second isolation plate 39 are scratched against the scraper 15 when they slide alternately. The mechanical stripping effect is used to remove the residual coal blocks on the surface, and the surface is kept clean continuously to avoid the secondary compaction of coal blocks that causes the anti-blocking function to fail. The scraper 15 will remove the coal attached to the first isolation plate 38 and the second isolation plate 39.

[0024] The isolation device 3 includes a bevel gear 31 rotatably mounted on the outer wall of the funnel bin 12, and a rocker 33 is rotatably mounted below the bevel gear 31. The rocker 33 converts the rotational motion into reciprocating swinging, distributes the movement amplitude through the hinge point, and realizes the symmetrical driving of the isolation plate. One end of the rocker 33 is hinged with a second hinged rod 35, and the lower end of the second hinged rod 35 is hinged with a second cross bar 36. The second cross bar 36 is connected to a plurality of second isolation plates 39 through a plurality of sliders. The swing of the rocker 33 drives the second cross bar 36 to slide up and down through the second hinged rod 35, and the sliding second cross bar 36 drives the plurality of second isolation plates 39 to slide up and down to form a dynamic shear gap. The end of the rocker 33 away from the second hinged rod 35 is hinged with a first hinged rod 34, and the lower end of the first hinged rod 34 is hinged with the first cross bar 3 7. The first cross bar 37 is connected to a plurality of first isolation plates 38 through a plurality of sliders. The rocker 33 swings through the first hinge rod 34 to drive the first cross bar 37 to slide back and forth. The sliding first cross bar 37 drives a plurality of first isolation plates 38 to slide back and forth. The first hinge rod 34 cooperates with the first cross bar 37 to symmetrically drive the first hinge rod 34, so that the first isolation plates 38 and the second isolation plates 39 form a staggered movement, thereby enhancing the tearing effect on the compacted coal blocks. The slider is set in the slide groove opened on the funnel bin 12 to slide, limiting the first isolation plates 38 and the second isolation plates 39 to slide only in the vertical direction, maintaining the contact pressure between the isolation plates and the scraper 15 stable, and ensuring the consistency of cleaning efficiency. The design of the slider and the slide groove eliminates lateral deviation through mechanical guidance, reduces movement resistance and prolongs the life of transmission components, and reduces maintenance requirements.

[0025] A rocker arm 33 located between the first hinged rod 34 and the second hinged rod 35 is rotatably installed on the outer wall of the funnel bin 12 and serves as a swing fulcrum to provide stable rotational freedom. The rocker arm 33 swings around this installation point to convert the rotational input into periodic swing. The swing of the rocker arm 33 drives the first hinged rod 34 and the second hinged rod 35 to slide up and down alternately, driving the first hinged rod 34 and the second hinged rod 35 to produce symmetrical reverse motion, forming an alternating shearing action of the first isolation plate 38 and the second isolation plate 39, so that a plurality of first isolation plates 38 and second isolation plates 39 slide up and down alternately, tearing off the coal blocks attached to the first isolation plates 38 and the second isolation plates 39, realizing self-cleaning, reducing maintenance requirements, and improving system reliability.

[0026] A crank 32 is hinged on the bevel gear 31 at a position close to the edge of the outer wall of the funnel bin 12. The bevel gear 31 forms an asymmetric power transmission structure with the crank 32 through an eccentric hinge point, and the output swing amplitude is amplified by the eccentric distance. The other end of the crank 32 is rotatably connected to one end of the rocker 33. This connection point is set on the rocker 33 at an end away from the second hinged rod 35. The power direction is distributed through phase difference to ensure the symmetrical movement of the first hinged rod 34 and the second hinged rod 35 on both sides, thereby avoiding transmission failure caused by unilateral overload. The rotation of the bevel gear 31 drives the crank 32 to rotate around the axis of the bevel gear 31, and the rotation of the crank 32 drives the end of the rocker 33 to swing back and forth up and down. The swinging rocker 33 drives the first hinged rod 34 and the second hinged rod 35 to slide up and down alternately, so that the first isolation plate 38 and the second isolation plate 39 form a dynamic shear gap, forcing the stripping of the compacted coal blocks and inhibiting secondary adhesion.

[0027] A mounting plate 25 is fixedly installed in the middle section of the inner part of the protective shell 22, and the motor 24 is fixedly installed on the mounting plate 25. The motor 24 is fixed to the middle part of the protective shell 22 through the mounting plate 25. The rigid support structure produces a centering positioning effect, reduces the impact of the vibration of the motor 24 on the shell, and improves the running stability. The transmission device 4 includes a first bevel gear 41 fixedly sleeved on the rotating shaft of the motor 24, and the first bevel gear 41 is arranged below the mounting plate 25. A first gear rod 42 is meshed on one side of the first bevel gear 41. The first gear rod 42 penetrates and is rotatably installed in a fixed rod 23. A second gear rod 43 is meshed below the end of the first gear rod 42 away from the motor 24. The second gear rod 43 is rotatably installed on the outer wall of the square warehouse 11, and the second gear rod 43 is vertically meshed with the first gear rod 42 at a right angle. The meshing structure produces a power steering effect, converting horizontal rotation into vertical transmission, adapting to the layout of the side wall of the warehouse body, and the lower end of the second gear rod 43 is meshed with two third gear rods 44, and the third gear rod 44 is symmetrically meshed on both sides of the second gear rod 43. The symmetrical transmission structure produces a power balancing effect to ensure that the isolation plates on both sides move synchronously to prevent unilateral jamming. The two third gear rods 44 are both installed on the outer wall of the funnel warehouse 12, and the end of the third gear rod 44 away from the second gear rod 43 is meshed with the fourth gear rod 45. The fourth gear rod 45 is rotatably installed on the side wall of the funnel warehouse 12 above the bevel gear 31, and the motor 24 drives the first bevel gear 41 to rotate through the rotating shaft, and the rotating first bevel gear 41 drives the first gear rod 42, the second gear rod 43, the third gear rod 44, and the fourth gear rod 45 to rotate in turn.

[0028] A worm 46 is fixedly sleeved on one end of the fourth gear rod 45 near the bevel gear 31, and a worm wheel 47 is meshed below the worm 46. The worm 46 transmits the rotational motion to the worm wheel 47, and the worm wheel 47 and the worm 46 produce a self-locking anti-reversal effect to ensure the stability of the one-way power transmission and prevent the isolation device 3 from retreating due to the resistance of the coal block. The worm wheel 47 is rotatably installed between the fourth gear rod 45 and the bevel gear 31. The worm wheel 47 meshes with the bevel gear 31, and a torque-increasing effect is generated through the reduction structure to convert the high speed of the motor 24 into a high torque output to meet the strong force requirement of the isolation plate tearing action. The rotating fourth gear rod 45 drives the worm wheel 47 to rotate through the worm 46, and the rotating worm wheel 47 drives the bevel gear 31 to rotate, and finally drives the first isolation plate 38 and the second isolation plate 39 to slide back and forth up and down to form dynamic shear to prevent coal blocks from adhering to the coal bin.

[0029] Sliding holes are provided at the bottom of both sides of the square bin 11. The top of the first isolation plate 38 and the second isolation plate 39 slides through the sliding holes during the sliding process. The sliding holes limit the sliding direction of the first isolation plate 38 and the second isolation plate 39 through the guide channel to ensure that they only move along the set trajectory to avoid friction loss caused by deflection. A baffle 13 is fixedly installed above the sliding hole inside the square bin 11. The baffle 13 is arranged above the first isolation plate 38 and the second isolation plate 39. The baffle 13 presses the first isolation plate 38 and the second isolation plate 39 downward to produce a downward pressure limiting effect, thereby suppressing the upward displacement of the first isolation plate 38 and the second isolation plate 39 caused by the resistance of coal blocks during the sliding process, maintaining the stability of the tearing action, and slidingly contacting with the top of the first isolation plate 38 and the second isolation plate 39 to produce a continuous scraping effect, automatically removing the coal blocks adhering to the top of the isolation plate, avoiding the accumulation of coal blocks affecting the sliding freedom, and reducing the need for manual maintenance.

[0030] When this embodiment is used, after the coal is put into the top of the distribution port 5, the conical screw 21 of the internal feeding device 2 rotates and stirs the coal, forcing the coal flow downward into the funnel bin 12; the isolation device 3 on both sides of the funnel bin 12 drives the first isolation plate 38 and the second isolation plate 39 to slide alternately through the transmission device 4, forming a dynamic gap to block the contact between the coal and the bin wall, and at the same time using shear force to tear the compacted coal blocks; the scraper 15 slides with the isolation plate to scrape the surface to remove residual coal blocks, and the baffle 13 is pressed down to limit and assist in cleaning; the worm wheel 47 and the worm 46 cooperate with the first bevel gear 41, the first gear rod 42, the second gear rod 43, the third gear rod 44, and the fourth gear rod 45 to ensure power synchronization and self-locking anti-reverse, and finally the coal blocks are discharged smoothly from the bottom of the funnel bin 12 through the screw 21.
