Description

Technical Field

[0001] The utility model belongs to the technical field of coal gangue storage bins, and particularly relates to a coal gangue feeding anti-blocking device. Background Technique

[0002] Coal gangue is a black rock that is much harder than coal discharged during the coal production process. Traditional reuse methods include using it for paving roads, ground filling, or land reclamation. Nowadays, with the improvement of reuse technology, it is crushed and then used in building materials such as refractory bricks, gangue cement, and lightweight concrete aggregates. It can also be used to produce chemical products such as aluminum chloride and sodium silicate;

[0003] After retrieval, the application (publication) number is: CN220431623U, which proposes a coal gangue resource utilization storage bin, "including a mounting frame, a reciprocating mechanism is installed on the mounting frame, a bin body is installed on the reciprocating mechanism, a power mechanism is installed on the bin body, two horizontal shafts and a power shaft member are installed on the power mechanism, the two horizontal shafts are respectively rotatably sleeved on both sides of the bin body, one end of the horizontal shaft is fixed with an eccentric wheel, the eccentric wheel corresponds to the mounting frame, a screw conveyor member is slidably installed at the lower end of the power shaft member, an installation groove is formed on the power shaft member, a second vibration assembly is installed in the installation groove, the second vibration assembly is fixedly connected to the screw conveyor member, and a lifting mechanism is installed on the screw conveyor member" and other technical features, "can well vibrate the storage bin, and can effectively lift the screw conveyor member in the storage bin, facilitate the turnover of coal gangue, and ensure the stable output of coal gangue, and can effectively ensure the output effect and quality" and other technical effects;

[0004] However, most of the components for anti-blocking in this device are located inside the bin body, which greatly occupies the internal space of the bin body. Moreover, the components contain power transmission components, and the powder contained in coal gangue will affect the power transmission. In addition, the pressure generated after the coal gangue is fully loaded will also affect the operation of the anti-blocking components and the use effect of the anti-blocking components;

[0005] Secondly, although the "screw conveyor member" can play an anti-blocking effect, its conveying capacity is limited by the space formed by the blades and the discharge port. The blades can only output the crushed stones contained in this space during a single rotation, and the output efficiency needs to be improved. Moreover, when the bin body is fully loaded, the blades will be subjected to a large pressure generated by the crushed stones, increasing the load of the "screw conveyor member";

[0006] To solve the above problems, a coal gangue feeding anti-blocking device is proposed in this application. Utility Model Content

[0007] The purpose of the utility model is to provide a coal gangue feeding anti-blocking device, which solves the problems put forward in the above background technique.

[0008] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0009] The present utility model is a coal gangue feeding anti-blocking device, including a bin body. A support for supporting is arranged at the bottom of the bin body. An output main pipe is communicated with the bottom of the support. A plurality of inclined pipes communicating with the output main pipe are circumferentially distributed on the outer circumference of the output main pipe. A vertical pipe is communicated with the bottom of the inclined pipe. A butterfly valve is arranged at the bottom of the vertical pipe. A plurality of the butterfly valves can be opened or closed synchronously. A discharge pipe is arranged at the bottom of the butterfly valve. A rotating conical spiral blade is arranged between the bin body and the output main pipe, and the tip of the conical spiral blade faces downward. A spiral rod circumferentially distributed with the conical spiral blade is also arranged between the bin body and the output main pipe.

[0010] Further, the total inner cavity of a plurality of circumferentially distributed inclined pipes is larger than the inner cavity of the output main pipe. An inclined through hole is arranged at the connection between the output main pipe and the inclined pipe. The inner diameters of the inclined pipe and the vertical pipe are equal.

[0011] Further, the butterfly valve is located directly below the vertical pipe, and the discharge pipe is located directly below the butterfly valve. A vertical feeding channel is formed among the vertical pipe, the butterfly valve, and the discharge pipe.

[0012] Further, an upper support is fixedly arranged at the lower end inside the bin body, and a lower support is fixedly arranged at the bottom of the output main pipe. A rotating linkage shaft is arranged between the spiral rod and the lower support, and the linkage shaft is coaxial with the output main pipe.

[0013] Further, both the conical spiral blade and the spiral rod are fixed on the linkage shaft. The overall diameter of the spiral rod is smaller than the inner diameter of the output main pipe. The diameter of the conical spiral blade gradually decreases from top to bottom, and the conical spiral blade is located directly above the central position of a plurality of inclined pipes.

[0014] Further, an output motor with an output end connected to the linkage shaft is fixedly arranged at the bottom of the output main pipe. The linkage shaft, the conical spiral blade, and the spiral rod rotate at the connection between the bin body and the output main pipe through the output motor.

[0015] Further, an extension rod extending outward is arranged on the disc inside the butterfly valve. A transmission box for linkage of the extension rod is arranged below the output main pipe. A valve motor for driving the discs inside a plurality of butterfly valves to rotate simultaneously through the transmission box is fixedly arranged at the lower end of the output main pipe.

[0016] The present utility model has the following beneficial effects:

[0017] By arranging the power transmission part of the anti-blocking component below the outside of the bin body, the anti-blocking component does not occupy a large amount of space inside the bin body. Accordingly, the coal gangue crushed powder will also reduce the influence on the transmission of the anti-blocking component, ensuring the service life while preventing blockage.

[0018] By providing a conical spiral blade and a screw rod, the conical spiral blade will form the "Bernoulli effect" after rotation, driving the crushed stones located below the conical spiral blade towards the output main pipe. The acting range of the force is larger, and it can effectively reduce the pressure generated by the crushed stones on the conical spiral blade. At the same time, a screw rod cooperating with the conical spiral blade is also provided. The screw rod can not only play a role in pushing and preventing blockage, but also will not affect the rapid passage of the crushed stones, ultimately achieving the purpose of improving the output efficiency of the crushed stones.

[0019] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0030] Please refer to Figures 1-5 As shown, the present invention is a coal gangue feeding anti-blocking device, which includes a bin body 1. A bracket 2 for support is arranged at the bottom of the bin body 1. The bottom of the bracket 2 is communicated with an output main pipe 3. The outer circumference of the output main pipe 3 is distributed with inclined pipes 4 communicating with it. The bottom of the inclined pipe 4 is communicated with a vertical pipe 5. A butterfly valve 6 is arranged at the bottom of the vertical pipe 5. Multiple butterfly valves 6 can be opened or closed synchronously. A discharge pipe 7 is arranged at the bottom of the butterfly valve 6. A rotating conical spiral blade 9 is arranged between the bin body 1 and the output main pipe 3, and the tip of the conical spiral blade 9 is downward. A spiral rod 10 distributed in a circle is also arranged between the bin body 1 and the output main pipe 3.

[0031] Among them, the total inner cavity of the multiple inclined pipes 4 distributed in a circle is larger than the inner cavity of the output main pipe 3. An inclined through hole is opened at the connection between the output main pipe 3 and the inclined pipe 4. The inner diameters of the inclined pipe 4 and the vertical pipe 5 are equal. In this embodiment, the cooperation of the inner cavity spaces of the output main pipe 3 and the multiple inclined pipes 4 ensures that after the crushed stones in the output main pipe 3 fall, the multiple inclined pipes 4 can quickly output the crushed stones downward, avoiding blockage. The inclined setting between the output main pipe 3 and the inclined pipe 4 can not only make room for the installation of the output motor 13, but also does not affect the stable output of the crushed stones.

[0032] Among them, the butterfly valve 6 is located directly below the vertical pipe 5, and the discharge pipe 7 is located directly below the butterfly valve 6. A vertical feeding channel is formed among the vertical pipe 5, the butterfly valve 6, and the discharge pipe 7. In this embodiment, the vertical channel formed by the vertical pipe 5, the butterfly valve 6, and the discharge pipe 7 can ensure the smoothness of the crushed stone feeding, and the butterfly valve 6 can also play a role in intercepting the flow.

[0033] Among them, an upper support 11 is fixedly arranged at the lower end inside the bin body 1, a lower support 12 is fixedly arranged at the bottom of the output main pipe 3, a rotating linkage shaft 8 is arranged between the screw rod 10 and the lower support 12, the linkage shaft 8 is coaxial with the output main pipe 3. In this embodiment, the entire top surface of the upper support 11 is provided with an inclined surface to prevent gravel accumulation, and the connection parts of the linkage shaft 8 with the upper support 11 and the lower support 12 are both driven by bearings.

[0034] Among them, the conical spiral blade 9 and the screw rod 10 are both fixed on the linkage shaft 8. The overall diameter of the screw rod 10 is smaller than the inner diameter of the output main pipe 3. The diameter of the conical spiral blade 9 gradually decreases from top to bottom, and the conical spiral blade 9 is located directly above the center position of a plurality of inclined pipes 4. In this embodiment, the large diameter at the upper end of the conical spiral blade 9 ensures the downward feeding effect, and the small diameter at the lower part leaves a passing space for gravel between it and the output main pipe 3. Then, under the action of the screw rod 10, the gravel can be output more smoothly. The position distribution of the conical spiral blade 9 and the inclined pipes 4 ensures that the gravel output through the conical spiral blade 9 can be directly conveyed outward by the plurality of inclined pipes 4, preventing blockage.

[0035] Among them, an output motor 13 with an output end connected to the linkage shaft 8 is fixedly arranged at the bottom of the output main pipe 3. The linkage shaft 8, the conical spiral blade 9, and the screw rod 10 rotate at the connection of the bin body 1 and the output main pipe 3 through the output motor 13. In this embodiment, the circumferentially distributed inclined pipes 4 provide an avoidance space for the installation of the output motor 13, and at the same time, it does not affect the conveying effect. By arranging the output motor 13 outside and directly driving the conical spiral blade 9 and the screw rod 10, the effective transmission of power is ensured.

[0036] Among them, the disc inside the butterfly valve 6 is provided with an outward extending rod, a transmission box 14 for the linkage of the extending rod is arranged below the output main pipe 3, and a valve motor 15 that drives the discs inside a plurality of butterfly valves 6 to rotate simultaneously through the transmission box 14 is fixedly arranged at the lower end of the output main pipe 3. In this embodiment, conical gears are arranged at the output ends of the disc extending rods inside the butterfly valve 6 and the valve motor 15. The gears on the valve motor 15 synchronously drive the gears on a plurality of extending rods to rotate, thereby realizing the simultaneous opening or closing of a plurality of butterfly valves 6.

[0037] It can be understood that first, the anti-blocking component is arranged outside the lower part of the bin body 1 to avoid excessive occupation of the internal space of the bin body 1, and it can also effectively reduce the influence of coal gangue gravel dust on the transmission parts of the anti-blocking component, ensuring the service life of the anti-blocking component. Secondly, the conical spiral blade 9 forms a "Bernoulli effect" after rotation, which can not only ensure the output efficiency but also not be affected by the large pressure of coal gangue gravel. Then, under the push of the screw rod 10, a better output effect is achieved.

[0038] A specific application of this embodiment is as follows: the butterfly valve 6 is in a closed state through the valve motor 15 and the transmission box 14. There are bevel gears inside the transmission box 14. One bevel gear connected to the valve motor 15 drives a plurality of bevel gears that cooperate with the internal sealing pieces of the butterfly valve 6, so as to realize the synchronous opening or closing of multiple butterfly valves 6. Coal gangue and gravel are stored in the bin 1 through the feed inlet at the top of the bin 1.

[0039] Feeding and output: Driven by the valve motor 15 and under the action of the transmission box 14, a plurality of butterfly valves 6 are driven to open simultaneously. The output motor 13 drives the conical spiral blade 9 and the screw rod 10 to rotate through the linkage shaft 8. The cooperation between the lower end of the conical spiral blade 9 and the output main pipe 3 creates enough space for the gravel to be discharged in part of the output main pipe 3. Then, under the push of the conical spiral blade 9 and the screw rod 10, the gravel is conveyed downward more efficiently and smoothly, and then discharged outward through multiple branched inclined pipes 4, vertical pipes 5, and discharge pipes 7.
