Description

Technical Field

[0001] This invention relates to the field of raw coal conveying technology, and more specifically, to a blockage-resistant, compartmentalized raw coal silo. Background Technology

[0002] In the production processes of industries such as power, building materials, energy, and chemicals, different types of coal need to be mixed and then transported to the coal feeder through a coal bunker. Existing coal bunkers typically consist of a square upper section and a funnel-shaped lower section. Conventional feeding devices use constant-diameter screws or gravity-feed coal. The constant cross-section of the constant-diameter screw cannot effectively concentrate the coal flow. During transportation, the coal disperses due to its own weight, forming local voids ("bridging phenomenon"). The loose coal flow accumulates in layers under gravity, increasing the friction between coal blocks and hindering overall flow, ultimately leading to blockages. The blocked coal remains in static contact with the bunker wall for a long period, causing... The weight of the coal block and the pressure of the upper coal flow cause plastic deformation at the contact surface, which embeds coal powder into the micropores on the surface of the bin wall, forming a physical adsorption layer. This significantly increases the adhesion force, making it easier for clogged coal to adhere to the bin wall. In existing technologies, vibration devices are usually installed on the bin wall to prevent coal from adhering to it by causing the bin wall to vibrate. However, since the vibration energy of the vibration device will continue to decay inside the bin, the vibration energy is only effective in the area near the vibration source. The bin wall far from the vibration source will still form an adhesion layer due to the stagnation of coal flow, which cannot effectively maintain the smooth flow inside the coal bin in the long term. If multiple sets of vibration sources are used to work together, the cost will be further increased. Summary of the Invention

[0003] The purpose of this invention is to provide a blockage-resistant, compartmentalized raw coal silo to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a clog-resistant, compartmented raw coal bunker is provided, including a distribution port. A square bin is fixedly connected below the distribution port, and a funnel bin is connected below the square bin. Different types of coal are fed into the distribution port and fall through the bottom of the funnel bin. A feeding device is installed inside the square bin. The feeding device rotates and pushes the coal into the funnel bin below the square bin. Two isolation devices are symmetrically arranged on the two side walls of the funnel bin. The isolation devices isolate the coal from the inner side wall of the funnel bin, and the coal falls downward along the isolation devices. When the isolation devices are working, they isolate the coal adhering to the side walls of the isolation devices. The feeding device tears apart the caking coal blocks, and the torn coal blocks fall from the bottom of the hopper. A transmission device is provided on one side of the feeding device. When the feeding device rotates, the transmission device drives the isolation device to remove the coal blocks attached to the isolation device. The bottom of the rotating feeding device continues to push the coal blocks falling from the isolation device downward. Several scrapers are fixedly installed on the side of the isolation device away from the side wall of the hopper. The scrapers are designed to be thick in the middle and thin at both sides. When the isolation device removes the caking coal blocks, it rubs against the scrapers, and the scrapers remove the coal attached to the isolation device.

[0005] As a further improvement to this technical solution, the feeding device includes a protective shell set at the top of a square bin. The outer wall of the protective shell is fixedly installed in the inner wall of the square bin by several fixing rods. A motor is fixedly installed inside the fixing rods. The rotating shaft of the motor passes through the bottom of the protective shell and is fixedly connected to a screw. The screw is set in a conical shape that is thicker at the top and thinner at the bottom. Spiral blades are provided on the side wall of the screw. The motor drives the screw to rotate through the rotating shaft. The rotating screw agitates the coal through the spiral blades, causing the coal to move downward and enter the hopper bin. A support rod is fixedly installed at the bottom of the hopper bin, and the bottom of the screw is rotatably mounted on the support rod.

[0006] As a further improvement to this technical solution, the isolation device includes a plurality of first isolation plates and second isolation plates that are slidably disposed on the inner sidewall of the hopper chamber. The plurality of first isolation plates and second isolation plates are staggered and the plurality of first isolation plates and second isolation plates isolate the coal from the inner sidewall of the hopper chamber. When the coal clumps together on the first isolation plates and second isolation plates, the staggered first isolation plates and second isolation plates pull and tear the coal clumps, and the torn coal clumps fall to the bottom of the hopper chamber.

[0007] As a further improvement to this technical solution, the first and second isolation plates are disposed between the scraper and the inner wall of the funnel chamber. The first and second isolation plates are in close contact with the scraper. When the first and second isolation plates slide alternately, they both rub against the scraper. The scraper removes the coal attached to the first and second isolation plates.

[0008] As a further improvement to this technical solution, the isolation device includes a helical gear rotatably mounted on the outer wall of the funnel chamber. A rocker arm is rotatably mounted below the helical gear. One end of the rocker arm is hinged to a second hinge rod, and the lower end of the second hinge rod is hinged to a second crossbar. The second crossbar is connected to several second isolation plates via several sliders. The rocker arm swings, causing the second crossbar to slide up and down repeatedly via the second hinge rod. The sliding second crossbar causes several second isolation plates to slide up and down repeatedly. The end of the rocker arm away from the second hinge rod is hinged to a first hinge rod, and the lower end of the first hinge rod is hinged to a first crossbar. The first crossbar is connected to several first isolation plates via several sliders. The rocker arm swings, causing the first crossbar to slide up and down repeatedly via the first hinge rod. The sliding first crossbar causes several first isolation plates to slide up and down repeatedly. The sliders are arranged in a groove opened on the funnel chamber to slide, restricting the first and second isolation plates to slide only in the vertical direction.

[0009] As a further improvement to this technical solution, a rocker arm located between the first hinge rod and the second hinge rod is rotatably installed on the outer wall of the funnel chamber. The rocker arm swings around this installation point, and the swinging of the rocker arm causes the first hinge rod and the second hinge rod to slide up and down alternately, causing several first isolation plates and second isolation plates to slide up and down alternately, tearing the coal blocks attached to the first isolation plates and second isolation plates.

[0010] As a further improvement to this technical solution, a crank is hinged to the outer side wall of the helical gear away from the funnel chamber near the edge. The other end of the crank is rotatably connected to one end of the rocker arm. This connection point is located on the rocker arm away from the second hinge rod. The rotation of the helical gear drives the crank to rotate around the axis of the helical gear. The rotation of the crank drives the end of the rocker arm to swing up and down reciprocally. The swinging rocker arm drives the first hinge rod and the second hinge rod to slide up and down alternately.

[0011] As a further improvement to this technical solution, an installation plate is fixedly installed in the middle section of the inner part of the protective shell. The motor is fixedly installed on the installation plate. The transmission device includes a first bevel gear fixedly sleeved on the motor shaft. The first bevel gear is located below the installation plate. A first gear rod meshes with one side of the first bevel gear. The first gear rod passes through and is rotatably installed in a fixed rod. A second gear rod meshes with the lower end of the first gear rod away from the motor. The second gear rod is rotatably installed on the outer wall of the square chamber. Two third gear rods mesh with the lower end of the second gear rod. Both third gear rods are installed on the outer wall of the funnel chamber. A fourth gear rod meshes with the end of the third gear rod away from the second gear rod. The fourth gear rod is rotatably installed on the side wall of the funnel chamber above the helical gear. The motor drives the first bevel gear to rotate through the shaft. The rotating first bevel gear sequentially drives the first gear rod, the second gear rod, the third gear rod, and the fourth gear rod to rotate.

[0012] As a further improvement to this technical solution, a worm gear is fixedly sleeved at one end of the fourth gear rod near the helical gear, and a worm wheel meshes below the worm gear. The worm wheel is rotatably installed between the fourth gear rod and the helical gear, and the worm wheel meshes with the helical gear. The rotating fourth gear rod drives the worm wheel to rotate through the worm gear, and the rotating worm wheel drives the helical gear to rotate.

[0013] As a further improvement to this technical solution, sliding holes are provided at the bottom of both sides of the square compartment. The top of the first and second isolation plates slide through the sliding holes during the sliding process. A baffle is fixedly installed above the sliding holes inside the square compartment. The baffle is positioned above the first and second isolation plates. The baffle presses down on the first and second isolation plates to limit their movement. The baffle slides in contact with the top of the first and second isolation plates.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In this anti-blockage compartmentalized raw coal bunker, the screw is driven by a motor to rotate, and the spiral blades forcefully push the coal downward. The tapered cross-section structure of the screw generates a downward gathering effect, reducing the accumulation of coal in the bunker and lowering the risk of initial blockage. At the same time, the motor drives the first and second isolation plates to slide alternately through the transmission device, generating bidirectional shearing force to forcibly break up the coal pieces adhering to the first and second isolation plates, thereby effectively preventing coal pieces from adhering and accumulating and getting stuck in the falling channel.

[0016] 2. In this anti-clogging compartmentalized raw coal bunker, when the first and second isolation plates slide alternately, they will make sliding contact with the parabolic scraper. The scraper scrapes the coal blocks on the first and second isolation plates, generating a mechanical stripping effect, which efficiently and continuously removes the residual coal blocks on the surface of the first and second isolation plates, inhibits the formation of secondary caking, and reduces the frequency of manual maintenance.

[0034] Example 1

[0035] Please see Figures 1-9As shown, the purpose of this embodiment is to provide a blockage-resistant, compartmentalized raw coal silo, including a feed inlet 5. A square silo 11 is fixedly connected below the feed inlet 5, and a funnel silo 12 is connected below the square silo 11. Different types of coal are fed into the feed inlet 5 and fall through the bottom of the funnel silo 12. A feeding device 2 is installed inside the square silo 11. The feeding device 2 rotates and pushes the coal into the funnel silo 12 below the square silo 11. The rigid support structure of the square silo 11 and the funnel silo 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 silo 12. The isolation devices 3 isolate the coal from the inner side wall of the funnel silo 12. The coal falls downward along the isolation devices 3. The isolation devices 3 prevent direct contact between the coal and the silo wall, reducing the probability of adhesion caused by friction. When working, the isolation devices 3 tear apart the caking coal lumps attached to the side wall of the isolation devices 3, breaking the coal through shearing force. The coal blocks are designed to adhere to the material, preventing coal block accumulation and blockage. Coal blocks torn by the isolation device 3 fall from the bottom of the funnel bin 12. A transmission device 4 is installed on one side of the feeding device 2, which drives the isolation device 3 to remove coal blocks attached to it. This achieves coordinated control of feeding and anti-blocking actions. The rotating bottom of the feeding device 2 continues to push the coal blocks falling from the isolation device 3 downwards. This continuous pushing ensures that the coal falls continuously without stagnation. Several scrapers 15 are fixedly installed on the side of the isolation device 3 away from the side wall of the funnel bin 12. The scrapers 15 are designed to be thick in the middle and thin at both sides. Their parabolic cross section efficiently removes residual coal blocks from the surface of the isolation device through scraping action, reducing the formation of secondary caking. When the isolation device 3 removes caking coal blocks, it scrapes against the scrapers 15. The scrapers 15 remove the coal attached to the isolation device 3. This periodic cleaning mechanism prevents long-term coal block adhesion from affecting equipment operation.

[0036] The feeding device 2 includes a protective shell 22 installed 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 by several fixing rods 23. The protective shell 22 encloses the internal mechanical structure to prevent coal dust from entering. 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 rods 23. The 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 as a cone shape with a thicker top and a thinner bottom. The cone-shaped screw 21 passes through... The gradually narrowing cross section gathers the coal downwards, reducing coal accumulation caused by uneven coal flow distribution within the hopper. Spiral blades are installed on the side wall of the screw 21. The motor 24 drives the screw 21 to rotate through the shaft. The rotating screw 21 agitates the coal through the spiral blades, causing the coal to move downwards and enter the hopper 12. The spiral blades forcefully push the coal downwards, avoiding stagnation and blockage caused by insufficient weight of the coal. A support rod 14 is fixedly installed at the bottom of the hopper 12. The bottom of the screw 21 is rotatably mounted on the support rod 14 to maintain axial stability and prevent a decrease in conveying efficiency caused by swaying.

[0037] The isolation device 3 includes several first isolation plates 38 and second isolation plates 39 that are slidably disposed on the inner wall of the funnel chamber 12. The several first isolation plates 38 and second isolation plates 39 are staggered. The first isolation plates 38 and second isolation plates 39 generate shear force through periodic sliding, tearing apart the caking coal lumps attached to the surface, blocking direct contact between the coal and the chamber wall, and reducing adhesion caused by friction. The several first isolation plates 38 and second isolation plates 39 isolate the coal from the inner wall of the funnel chamber 12 to prevent the coal from caking on the chamber wall. When the coal caking into lumps on the first isolation plates 38 and second isolation plates 39, the staggered sliding isolation plates apply bidirectional tensile force to the coal lumps through relative displacement, destroying the internal structure of the coal lumps and causing them to break apart, preventing large pieces of coal from blocking the falling channel; the torn coal lumps fall to the bottom of the funnel chamber 12, ensuring stable anti-blocking effect during long-term operation.

[0038] The first isolation plate 38 and the second isolation plate 39 are disposed between the scraper 15 and the inner wall of the funnel hopper 12. The first isolation plate 38 and the second isolation plate 39 are in close contact with the scraper 15. When the first isolation plate 38 and the second isolation plate 39 slide alternately, they both rub against the scraper 15, using mechanical peeling to remove residual coal lumps from the surface, continuously keeping the surface clean, and avoiding secondary coal caking that would cause the anti-blocking function to fail. The scraper 15 removes the coal attached to the first isolation plate 38 and the second isolation plate 39.

[0039] The isolation device 3 includes a helical gear 31 rotatably mounted on the outer wall of the funnel chamber 12. A rocker arm 33 is rotatably mounted below the helical gear 31. The rocker arm 33 converts rotational motion into reciprocating oscillation, distributing the amplitude of motion through hinge points to achieve symmetrical drive of the isolation plates. One end of the rocker arm 33 is hinged to a second hinge rod 35, and the lower end of the second hinge rod 35 is hinged to a second crossbar 36. The second crossbar 36 is connected to several second isolation plates 39 via several sliders. The oscillation of the rocker arm 33 drives the second crossbar 36 to slide up and down reciprocally via the second hinge rod 35. The sliding second crossbar 36 drives the several second isolation plates 39 to slide up and down reciprocally, forming a dynamic shearing gap. The end of the rocker arm 33 away from the second hinge rod 35 is hinged to a first hinge rod 34, and the lower end of the first hinge rod 34 is hinged to a first crossbar 36. 7. The first crossbar 37 is connected to several first isolation plates 38 via several sliders. The rocker arm 33 swings and drives the first crossbar 37 to slide up and down repeatedly via the first hinge rod 34. The sliding first crossbar 37 drives several first isolation plates 38 to slide up and down repeatedly. In conjunction with the first hinge rod 34, the first crossbar 37 is symmetrically driven, so that the first isolation plates 38 and the second isolation plates 39 form an alternating motion, which enhances the tearing effect on the caking coal blocks. The sliders are set in the sliding grooves opened on the funnel bin 12 to slide, which restricts the first isolation plates 38 and the second isolation plates 39 to slide only in the vertical direction, maintains the stable contact pressure between the isolation plates and the scraper 15, and ensures the consistency of cleaning efficiency. The design of the sliders and the sliding grooves eliminates lateral offset through mechanical guidance, reduces motion resistance and extends the life of transmission components, and reduces maintenance requirements.

[0040] A rocker arm 33, located between the first hinge rod 34 and the second hinge rod 35, is rotatably mounted on the outer wall of the funnel chamber 12 and serves as a pivot point to provide stable rotational freedom. The rocker arm 33 swings around this mounting point, converting the rotational input into periodic oscillation. The swing of the rocker arm 33 causes the first hinge rod 34 and the second hinge rod 35 to slide up and down alternately, driving the first hinge rod 34 and the second hinge rod 35 to produce symmetrical opposite movements, forming an alternating shearing action of the first isolation plate 38 and the second isolation plate 39. This causes several first isolation plates 38 and second isolation plates 39 to slide up and down alternately, tearing the coal lumps attached to the first isolation plates 38 and the second isolation plates 39, achieving self-cleaning, reducing maintenance requirements, and improving system reliability.

[0041] A crank 32 is hinged to the outer wall of the helical gear 31 near the edge of the funnel hopper 12. The helical gear 31 and the crank 32 form an asymmetrical power transmission structure through an eccentric hinge point, which amplifies the output swing amplitude by utilizing the eccentricity. The other end of the crank 32 is rotatably connected to one end of the rocker arm 33. This connection point is located on the rocker arm 33 at the end away from the second hinge rod 35. The power direction is distributed through the phase difference to ensure the symmetrical movement of the first hinge rod 34 and the second hinge rod 35 on both sides, avoiding transmission failure caused by unilateral overload. The rotation of the helical gear 31 drives the crank 32 to rotate around the axis of the helical gear 31. The rotation of the crank 32 drives the end of the rocker arm 33 to swing up and down. The swinging rocker arm 33 drives the first hinge rod 34 and the second hinge rod 35 to slide up and down alternately, so that the first isolation plate 38 and the second isolation plate 39 form a dynamic shearing gap, which forcibly peels off the caking coal blocks and inhibits secondary adhesion.

[0042] An mounting plate 25 is fixedly installed in the middle section of the inner part of the protective shell 22. The motor 24 is fixedly installed on the mounting plate 25. The mounting plate 25 fixes the motor 24 to the middle of the protective shell 22. The rigid support structure provides a central positioning effect, reducing the impact of motor 24 vibration on the shell and improving operational stability. The transmission device 4 includes a first bevel gear 41 fixedly sleeved on the rotating shaft of the motor 24. The first bevel gear 41 is located below the mounting plate 25. A first gear rod 42 meshes with one side of the first bevel gear 41. The first gear rod 42 passes through and is rotatably installed in a fixed rod 23. A second gear rod 43 meshes with the lower part 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 compartment 11. The second gear rod 43 meshes perpendicularly with the first gear rod 42 at a right angle. The meshing structure generates a power steering effect, converting horizontal rotation into vertical transmission, adapting to the layout of the hopper side wall. The lower end of the second gear rod 43 meshes with two third gear rods 44, which are symmetrically meshed on both sides of the second gear rod 43. The symmetrical transmission structure generates a power balance effect, ensuring that the isolation plates on both sides move synchronously and preventing one-sided jamming. Both third gear rods 44 are installed on the outer side wall of the funnel hopper 12. The end of the third gear rod 44 away from the second gear rod 43 meshes with a fourth gear rod 45. The fourth gear rod 45 is rotatably installed on the side wall of the funnel hopper 12 above the helical gear 31. The motor 24 drives the first bevel gear 41 to rotate through the rotating shaft. 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 sequence.

[0043] A worm gear 46 is fixedly sleeved at one end of the fourth gear rod 45 near the helical gear 31. A worm wheel 47 meshes below the worm gear 46. The worm gear 46 transmits rotational motion to the worm wheel 47. The worm wheel 47 and the worm gear 46 have a self-locking anti-reverse function to ensure the stability of unidirectional power transmission and prevent the isolation device 3 from retracting due to coal block resistance. The worm wheel 47 is rotatably installed between the fourth gear rod 45 and the helical gear 31. The worm wheel 47 meshes with the helical gear 31 and generates a torque-increasing effect through the reduction structure, converting the high speed of the motor 24 into high torque output to meet the strong demand of the tearing action of the isolation plate. The rotating fourth gear rod 45 drives the worm wheel 47 to rotate through the worm gear 46. The rotating worm wheel 47 drives the helical gear 31 to rotate, which ultimately drives the first isolation plate 38 and the second isolation plate 39 to slide up and down to form dynamic shearing, preventing coal blocks from adhering to the coal bunker.

[0044] The bottom of both sides of the square bin 11 is provided with sliding holes. The top of the first isolation plate 38 and the second isolation plate 39 slide through the sliding holes during the sliding process. The sliding holes restrict the sliding direction of the first isolation plate 38 and the second isolation plate 39 through the guide channel, ensuring that they only move along the set trajectory and avoiding frictional wear caused by deflection. A baffle 13 is fixedly installed above the sliding holes inside the square bin 11. The baffle 13 is set above the first isolation plate 38 and the second isolation plate 39. The baffle 13 presses down on the first isolation plate 38 and the second isolation plate 39 to produce a downward pressure limiting effect, suppressing the upward displacement of the first isolation plate 38 and the second isolation plate 39 caused by the resistance of coal during the sliding process, maintaining the stability of the tearing action, and sliding in contact 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 pieces adhering to the top of the isolation plates, avoiding the accumulation of coal pieces affecting the degree of freedom of sliding, and reducing the need for manual maintenance.

[0045] In this embodiment, after coal is fed into the top of the feed inlet 5, it is agitated by the rotating conical screw 21 of the internal feeding device 2, which forces the coal flow downward into the funnel bin 12. The isolation devices 3 on both sides of the funnel bin 12 drive 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 coal from contacting the bin wall, while using shear force to tear apart the caking coal blocks. The scraper 15 slides with the isolation plate to scrape the surface and remove residual coal blocks, and the baffle 13 presses down to limit and assist in cleaning. The worm gear 47 and worm 46 work together 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 transmission. Finally, the coal blocks are smoothly discharged through the bottom of the funnel bin 12 via the screw 21.
