Description

Technical Field

[0001] This utility model relates to the field of coal hopper technology, and in particular to a coal hopper with a cleaning function. Background Technology

[0002] A coal hopper is a container used for storing and transporting coal. During coal combustion or processing, the coal hopper can play a role in feeding the coal evenly and ensuring a stable supply of coal. It is commonly used in technical fields such as the power industry and metallurgy.

[0003] In practice, some coals have high moisture content and caking properties, resulting in poor coal flowability. As a result, some coal slag tends to stick to the walls of the coal hopper and cause blockages, affecting the operation of the coal hopper. Existing common methods for clearing blockages include installing a vibrating device on the coal hopper to vibrate and remove the attached coal slag, or installing coal shovels. However, vibrating devices can easily damage the coal hopper when they are in operation, and coal shovels require manual intervention, resulting in low clearing efficiency.

[0004] Therefore, a coal hopper with a cleaning function that can improve the unblocking efficiency without damaging the coal hopper was proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a coal hopper with a cleaning function, which improves the unblocking efficiency without damaging the coal hopper.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a coal hopper with a cleaning function, comprising: a coal hopper body, wherein a discharge port is provided at the bottom;

[0007] The coal hopper body is provided with a blockage-clearing component, including a conveying plate hinged to the side wall corresponding to the discharge port. A reset element is also provided between the discharge port and the conveying plate for applying a pulling force to the conveying plate in a direction away from the center of the discharge port. A pressing component is also provided on one side of the discharge port, and the pressing component is detachably connected to the conveying plate and applies a pressing force to it in a direction closer to the center of the discharge port.

[0008] Furthermore, the discharge port is provided with two oppositely arranged conveyor plates, and the extrusion assembly is detachably connected to the two conveyor plates and applies a thrust to each conveyor plate toward the center of the discharge port.

[0009] Furthermore, multiple opposing first grooves are provided on both sides of the discharge port corresponding to the conveying plate;

[0010] The feeding plate includes two hinged seats hinged at the discharge port, one of which is located below the other. Multiple connecting rods are distributed from top to bottom between the two hinged seats. Each connecting rod's two ends correspond to one of the first sliding grooves and are slidably disposed within the corresponding first sliding groove. A movable plate for changing the shape of the discharge port is rotatably disposed between adjacent connecting rods. Another movable plate is rotatably disposed between each hinged seat and the corresponding connecting rod. When the extrusion assembly is connected to the corresponding movable plate or connecting rod, the extrusion assembly applies an extrusion force toward the center of the discharge port.

[0011] The reset element includes a plurality of elastic units respectively disposed between each of the first slide grooves and the corresponding connecting rods, and each elastic unit applies a pulling force to the corresponding connecting rod in a direction away from the center of the discharge port.

[0012] Furthermore, a protective cover is provided around the discharge port to protect the unblocking component;

[0013] The extrusion assembly includes two transmission rods rotatably disposed within the protective cover. Each transmission rod is disposed on the side of the corresponding feeding plate away from the discharge port. Each transmission rod is also provided with an extrusion block. When the transmission rod rotates, the extrusion block contacts the corresponding movable plate or the connecting rod and applies an extrusion force toward the center of the discharge port.

[0014] The protective cover is also equipped with a power unit. The moving end of the power unit is connected to one of the transmission rods. A belt drive assembly is also provided between the power unit and the other transmission rod. The power unit drives the two transmission rods to rotate synchronously through the belt drive assembly.

[0015] Furthermore, a guide groove is provided at the discharge port, and the guide groove is located below each of the conveying plates;

[0016] A telescopic plate is also provided on one side of the discharge port. The telescopic end of the telescopic plate is slidably disposed in the guide groove. The telescopic plate is used to open or close the discharge port.

[0017] Furthermore, an air inlet is provided at the top of the coal hopper body;

[0018] The inner wall of the coal hopper body is also surrounded by a gas supply pipe, which is connected to the gas inlet and has multiple gas outlets at the bottom. The gas supply pipe is used to supply airflow to the inner wall of the coal hopper body.

[0019] The beneficial effects of this utility model are reflected in:

[0020] This invention utilizes a blockage-clearing component. The extrusion assembly applies a pressing force to the conveyor plates near the center of the discharge port, causing the conveyor plates to move towards the center of the discharge port until the extrusion assembly separates from each conveyor plate. At this point, the reset element drives the conveyor plates to move away from the center of the discharge port until the extrusion assembly contacts each conveyor plate again. This periodically changes the shape of the inner wall of the discharge port through the conveyor plates, allowing the accumulated coal at the discharge port to fall off, thus preventing coal from accumulating and causing blockages at the discharge port. The entire process does not damage the coal hopper and improves the blockage-clearing efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figure 1-5This utility model discloses a coal hopper with a cleaning function, including a coal hopper body 01, which has a discharge port 011 at the bottom;

[0030] In one embodiment, the coal hopper body 01 is provided with a blockage-clearing component 1, including a conveying plate 11 hinged to the side wall of the discharge port 011. A reset element is also provided between the discharge port 011 and the conveying plate 11. The reset element applies a pulling force to the conveying plate 11 in a direction away from the center of the discharge port 011. A pressing component 12 is also provided on one side of the discharge port 011. The pressing component 12 is detachably connected to the side of the conveying plate 11 away from the center of the discharge port 011. The pressing component 12 is used to apply a pressing force to each conveying plate 11 in a direction close to the center of the discharge port 011.

[0031] In practice, when coal enters the coal hopper body 01 and is conveyed, the extrusion assembly 12 contacts the conveying plate 11 and applies an extrusion force toward the center of the discharge port 011, thereby causing the conveying plate 11 to move toward the discharge port 011, thereby periodically changing the shape of the inner wall of the discharge port 011, preventing coal from accumulating at the discharge port 011, and allowing the accumulated coal at the discharge port 011 to fall off.

[0032] In this invention, through the operation of the unblocking component 1, the extrusion assembly 12 applies extrusion force to the conveying plate 11 towards the center of the discharge port 011, thereby causing the conveying plate 11 to move towards the center of the discharge port 011 until the extrusion assembly 12 separates from each conveying plate 11. At this time, the reset element drives the conveying plate 11 to move away from the center of the discharge port 011 until the extrusion assembly 12 contacts each conveying plate 11 again. Thus, by periodically changing the inner wall shape of the discharge port 011 through the conveying plate 11, the accumulated coal at the discharge port 011 falls off, thereby preventing coal from accumulating at the discharge port 011 and causing blockage. The whole process does not damage the coal hopper and can improve the unblocking efficiency.

[0033] In one embodiment, the discharge port 011 is provided with two oppositely arranged conveyor plates 11, and the extrusion assembly 12 is detachably connected to the two conveyor plates 11. When the extrusion assembly 12 contacts each conveyor plate 11, the extrusion assembly 12 applies a thrust to each conveyor plate 11 in the direction close to the center of the discharge port 011, thereby further improving the effect of changing the inner wall shape of the discharge port 011 and improving the anti-blocking efficiency.

[0034] In one embodiment, the discharge port 011 is provided with a plurality of oppositely arranged first grooves 012 on both sides of the conveying plate 11;

[0035] The feeding plate 11 includes two hinge seats 111 hinged at the discharge port 011. One hinge seat 111 is located below the other hinge seat 111. A plurality of connecting rods 112 are distributed from top to bottom between the two hinge seats 111. The two ends of each connecting rod 112 correspond to each first slide groove 012 and are slidably disposed in the corresponding first slide groove 012. A movable plate 113 for changing the shape of the discharge port 011 is provided between two adjacent connecting rods 112. The two ends of the movable plate 113 are rotatably disposed on the corresponding connecting rod 112. Another movable plate 113 is provided between each hinge seat 111 and the corresponding connecting rod 112. The two ends of the corresponding movable plate 113 are rotatably disposed on the corresponding hinge seat 111 and the corresponding connecting rod 112. When the extrusion assembly 12 is connected to the corresponding movable plate 113 or the connecting rod 112, the extrusion assembly 12 applies an extrusion force toward the center of the discharge port 011.

[0036] The reset element includes a plurality of elastic units 13 respectively disposed between each first slide groove 012 and the corresponding connecting rod 112, and each elastic unit 13 applies a pulling force to the corresponding connecting rod 112 in a direction away from the center of the discharge port 011.

[0037] With this design, when the coal enters the coal hopper body 01, the extrusion assembly 12 connects to the corresponding movable plate 113 or connecting rod 112 and applies extrusion force towards the center of the discharge port 011, thereby causing the corresponding connecting rod 112 to move closer to the center of the discharge port 011, while simultaneously driving the corresponding movable plate 113 to rotate. At this time, the shape of the discharge port 011 changes. Subsequently, when the extrusion assembly 12 separates from the corresponding movable plate 113 or connecting rod 112, the corresponding elastic unit 13 loses its constraint and drives the corresponding connecting rod 112 to move away from the discharge port 011. The corresponding movable plate 113 rotates with the movement of the corresponding connecting rod 112, at which point the shape of the discharge port 011 is restored, thereby creating an "intestinal peristalsis" effect at the discharge port 011, so as to avoid coal accumulation by periodically changing the shape of the discharge port 011.

[0038] In one embodiment, a protective cover 2 for protecting the unblocking component 1 is provided around the discharge port 011;

[0039] The extrusion assembly 12 includes two transmission rods 121 rotatably disposed within the protective cover 2. Each transmission rod 121 is disposed on the side of the corresponding conveying plate 11 away from the discharge port 011. Each transmission rod 121 is also provided with an extrusion block 122. When the transmission rod 121 rotates, the extrusion block 122 contacts the corresponding movable plate 113 or connecting rod 112 and applies an extrusion force toward the center of the discharge port 011. The protective cover 2 is also provided with a power unit 123. The moving end of the power unit 123 is connected to one of the transmission rods 121. A belt drive assembly 14 is also provided between the power unit 123 and the other transmission rod 121. The power unit 123 drives the two transmission rods 121 to rotate synchronously through the belt drive assembly 14.

[0040] With this design, when the coal enters the coal hopper body 01, the power unit 123 drives the two transmission rods 121 to rotate together through the belt transmission assembly 14. Each transmission rod 121 drives the corresponding extrusion block 122 to rotate and extrudes the corresponding movable plate 113 or connecting rod 112 towards the discharge port 011, thereby driving the corresponding connecting rod 112 to move until the extrusion block 122 separates from the corresponding movable block. Each connecting rod 112 moves away from the center of the discharge port 011 through the elastic unit 13.

[0041] It should be noted that the belt drive assembly 14 includes two synchronous pulleys 141 respectively disposed on the moving end of the power unit 123 and the corresponding transmission rod 121, and a synchronous belt 142 connecting the two synchronous pulleys 141. When the power unit 123 drives the corresponding transmission rod 121 to rotate, the synchronous pulley 141 disposed on the power unit 123 drives the synchronous pulley 141 on the other transmission rod 121 through the synchronous belt 142, thereby realizing the synchronous rotation of the two transmission rods 121.

[0042] It should be noted that multiple extrusion blocks 122 may be circumferentially distributed on each transmission rod 121, thereby increasing the frequency of extrusion on the corresponding conveying plate 11 and improving the anti-blocking efficiency.

[0043] In one embodiment, a guide groove 013 is also provided at the discharge port 011, and the guide groove 013 is located below each conveying plate;

[0044] A telescopic plate 3 is also provided on one side of the discharge port 011. The telescopic end of the telescopic plate 3 is slidably disposed in the guide groove 013. The telescopic plate 3 is used to open or close the discharge port 011.

[0045] With this design, when it is necessary to stop the coal conveying, the telescopic end of the telescopic plate 3 moves towards the discharge port 011 until the telescopic plate 3 closes the discharge port 011, thus preventing the coal from leaking out accidentally.

[0046] Preferably, the telescopic plate 3 can be an electric telescopic plate 3 as in the prior art.

[0047] In one embodiment, a gas inlet 014 is provided on the top of the coal hopper body 01;

[0048] The inner wall of the coal hopper body 01 is also surrounded by a gas supply pipe 4, which is connected to the gas supply port 014 and has multiple gas outlets 41 at the bottom. The gas supply pipe 4 is used to supply airflow to the inner wall of the coal hopper body 01.

[0049] With this design, when transporting coal, the external gas conveying component (not shown in the figure) delivers hot air into the gas conveying pipe through the gas inlet. The hot air is discharged into the inner wall of the coal hopper body through each gas outlet, thereby increasing the inner wall temperature and reducing the moisture content of the coal, thus reducing the adhesion of the coal.

[0050] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0051] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0052] Additionally, "multiple" refers to two or more.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
