Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, and in particular relates to a dust suppression device for conveyors. Background Technology

[0002] Dust suppression devices for conveyors are designed to reduce dust pollution generated during material transportation. Dust is frequently generated during transport due to friction and collisions, especially with materials like ores, coal, and sand. Long-term accumulation of dust not only pollutes the environment but also harms the health of operators. Therefore, dust suppression devices play a crucial role.

[0003] According to a public notice (publication number: CN 216140906U), a belt conveyor unloading vehicle that can effectively suppress dust has a three-way funnel at the unloading port of the unloading vehicle body. The lower part of the three-way funnel is connected to the unloading chute located on both sides of the unloading vehicle body. The lower end of the unloading chute is opposite to the hopper opening. Dust collectors are installed on both sides of the unloading chute and fixed on the frame of the unloading vehicle body. A dust collection hood is installed below the dust collector and covers the hopper opening.

[0004] In the aforementioned application, the cooperation between components such as the unloading vehicle body and the three-way funnel makes it difficult to solve the problem of accurately adjusting the spray volume according to the amount of dust and specifically suppressing dust of different particle sizes, and flexibly adapting to changes in the conveyor's operating conditions. This results in increased water flow, making it difficult to save water resources and failing to specifically suppress dust of different particle sizes, which needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a dust suppression device for a conveyor. By cooperating with the nozzles, adjusting plates and other components inside the dust suppression spray adjustment assembly, it solves the problem that existing devices cannot accurately adjust the spray volume according to the amount of dust and specifically suppress dust of different particle sizes, thus flexibly adapting to changes in conveyor operating conditions.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a dust suppression device for a conveyor, comprising a conveyor, a support structure on the side of the conveyor, a dust cover on the side of the support structure, a spray assembly on the inner wall of the dust cover, a pipeline system on the side of the conveyor, a guardrail on the side of the conveyor, a dust suppression spray adjustment assembly inside the spray assembly, the dust suppression spray adjustment assembly including a nozzle, one end of the nozzle penetrating through the bottom of the spray assembly, a middle frame fixedly connected to the inner wall of the nozzle, a large slot and a small slot on the top of the middle frame, an adjustment plate rotatably connected to the inner wall of the middle frame, and a handle fixedly connected to the top of the adjustment plate.

[0008] Furthermore, several large slots are provided and arranged in a circular array at the bottom of the middle frame. The presence of several large slots facilitates the downward flow of more water, resulting in a larger volume of water being sprayed out.

[0009] Furthermore, several small slots are provided and arranged in a circular array at the bottom of the middle frame. The presence of several small slots helps to allow less water to flow downwards, resulting in less water being sprayed out.

[0010] Furthermore, the adjusting plate is located at the top of the large and small slots, a design that allows for adjustment of the exposed area of ​​the large and small slots when the adjusting plate is rotated.

[0011] Furthermore, the bottom of the handle is slidably connected to the outer wall of the nozzle. Several nozzles are arranged in a linear array at the bottom of the spray assembly. Having several nozzles facilitates simultaneous spraying and improves dust suppression efficiency.

[0012] Furthermore, the pipeline system is located on the side of the conveyor, and two guardrails are provided, which are symmetrical to each other along the vertical central axis of the conveyor. Providing two guardrails is beneficial for protecting the conveyor.

[0013] Furthermore, an anti-clogging component is provided on the outer wall of the nozzle. The anti-clogging component includes a squeezing rod, one end of which is fixedly connected to the side of the handle. A bracket is fixedly connected to the outer wall of the nozzle, and a turntable is rotatably connected to the inner wall of the bracket. An inclined rod is fixedly connected to the circumference of the turntable, and a vibrating rod is fixedly connected to the circumference of the turntable. When the handle moves, the squeezing rod squeezes the inclined rod, causing the turntable and the vibrating rod to rotate. This causes the vibrating rod to strike the outer wall of the nozzle, loosening the large and small grooves inside the nozzle and preventing clogging.

[0014] Furthermore, the inclined rod is located on the displacement trajectory of the extrusion rod, and a controller is provided on the side of the conveyor. This design is beneficial because the inclined rod can be directly extruded when the extrusion rod moves.

[0015] Furthermore, the vibrating rod is located on the side of the nozzle, and the nozzle is located on the displacement trajectory of the vibrating rod. This design allows the vibrating rod to directly strike the outer wall of the nozzle when it moves.

[0016] Furthermore, a torsion spring is fixedly connected to the side of the turntable, and the end of the torsion spring away from the turntable is fixedly connected to the side of the bracket. The design of the torsion spring is beneficial to the automatic reset of the vibration rod when the turntable is not driven.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model achieves precise adjustment of spray volume according to dust volume by cooperating with the nozzles, adjustment plates and other components inside the dust suppression spray adjustment component. When the dust is heavy, the flow rate is increased to enhance dust suppression, and when the dust is light, the flow rate is reduced to save water resources. Different slots and adjustment plates can form water mists of different densities to specifically suppress dust of different particle sizes. It can flexibly adapt to changes in conveyor conditions, such as changes in material type and conveying speed that cause changes in dust, and always maintain effective dust suppression.

[0019] 2. This utility model achieves the goal of clearing the nozzle slot through vibration by cooperating with the vibration rod, extrusion rod and other components inside the anti-clogging component, thus preventing clogging and ensuring continuous and effective dust suppression by spraying. The automatic reset structure ensures that the vibration device can work repeatedly without frequent manual maintenance, ensuring continuous and stable spraying and improving the overall reliability and dust suppression efficiency of the conveyor dust suppression device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0030] Please see Figures 1-5 As shown, this utility model is a dust suppression device for a conveyor, including a conveyor 1, a support structure 2 on the side of the conveyor 1, a dust cover 3 on the side of the support structure 2, a spray assembly 4 on the inner wall of the dust cover 3, a pipeline system 5 on the side of the conveyor 1, a guardrail 6 on the side of the conveyor 1, and a dust suppression spray adjustment assembly 7 inside the spray assembly 4. The dust suppression spray adjustment assembly 7 includes a nozzle 71, one end of which penetrates the bottom of the spray assembly 4. A middle frame 72 is fixedly connected to the inner wall of the nozzle 71. A large slot 73 and a small slot 74 are opened at the top of the middle frame 72. An adjustment plate 75 is rotatably connected to the inner wall of the middle frame 72, and a handle 76 is fixedly connected to the top of the adjustment plate 75.

[0031] Several large slots 73 are provided and arranged in a circular array at the bottom of the middle frame 72. The presence of several large slots 73 facilitates the downward flow of more water, resulting in a larger amount of water being sprayed out.

[0032] Several small slots 74 are provided and arranged in a circular array at the bottom of the middle frame 72. The presence of several small slots 74 helps to allow less water to flow downwards, resulting in less water being sprayed out.

[0033] The adjusting plate 75 is located on top of the large slot 73 and the small slot 74. This design is beneficial for adjusting the exposed area of ​​the large slot 73 and the small slot 74 when rotating the adjusting plate 75.

[0034] The bottom of the handle 76 is slidably connected to the outer wall of the nozzle 71. Several nozzles 71 are arranged in a linear array at the bottom of the spray assembly 4. The arrangement of several nozzles 71 facilitates simultaneous spraying and improves dust suppression efficiency.

[0035] The pipeline system 5 is located on the side of the conveyor 1. There are two guardrails 6, which are symmetrical to each other along the vertical central axis of the conveyor 1. The two guardrails 6 are beneficial to the protection of the conveyor 1.

[0036] An anti-clogging component 8 is provided on the outer wall of the nozzle 71. The anti-clogging component 8 includes a squeezing rod 81, one end of which is fixedly connected to the side of the handle 76. A bracket 82 is fixedly connected to the outer wall of the nozzle 71. A turntable 83 is rotatably connected to the inner wall of the bracket 82. An inclined rod 84 is fixedly connected to the circumference of the turntable 83. A vibrating rod 85 is fixedly connected to the circumference of the turntable 83. When the handle 76 moves, the squeezing rod 81 squeezes the inclined rod 84, causing the turntable 83 and the vibrating rod 85 to rotate. This causes the vibrating rod 85 to strike the outer wall of the nozzle 71, loosening the large groove 73 and the small groove 74 inside the nozzle 71 and preventing clogging.

[0037] The inclined bar 84 is located on the displacement trajectory of the extrusion bar 81. The controller 9 is provided on the side of the conveyor 1. This design is beneficial to directly extruding the inclined bar 84 when the extrusion bar 81 moves.

[0038] The vibrating rod 85 is located on the side of the nozzle 71, and the nozzle 71 is located on the displacement trajectory of the vibrating rod 85. This design allows the vibrating rod 85 to directly strike the outer wall of the nozzle 71 when it moves.

[0039] A torsion spring 86 is fixedly connected to the side of the turntable 83. The end of the torsion spring 86 away from the turntable 83 is fixedly connected to the side of the bracket 82. The design of the torsion spring 86 is conducive to the automatic reset of the vibration rod 85 when the turntable 83 is not driven.

[0040] A specific application of this embodiment is as follows: Conveyor 1 serves as a dust source, stably supported by support structure 2. Dust cover 3 covers the area above conveyor 1, limiting the dust diffusion range. Pipeline system 5 delivers water to spray assembly 4. Spray assembly 4 sprays water mist of different densities inside dust cover 3. Simultaneously, guardrail 6 ensures the safety of personnel during operation and maintenance. When dust rises at the bottom of dust cover 3, it is captured and settled by the water mist sprayed by spray assembly 4. Pipeline system 5 continuously supplies water to ensure uninterrupted spraying. Support structure 2 and conveyor 1 operate stably, jointly achieving efficient dust suppression and effectively controlling dust pollution. Spray assembly 4 typically sprays water mist through nozzles 71. Several nozzles 71 are provided to increase the spray volume and improve the dust suppression effect. An intermediate frame 72 is installed inside the nozzle 71. Water flowing into the nozzle 71 passes through the intermediate frame 72. A large groove is opened at the top of the intermediate frame 72. Water passing through the middle frame 72 can only be sprayed out of the nozzle 71 through the large slot 73 and the small slot 74. The top of the large slot 73 and the small slot 74 has a rotating adjustment plate 75. The presence of the adjustment plate 75 blocks part of the exposed area of ​​the large slot 73 and the small slot 74. By gripping the handle 76 and rotating it, the adjustment plate 75 can be rotated, which can change the exposed area of ​​the large slot 73 and the small slot 74, thereby adjusting the water flow rate and the amount of spray from the nozzle 71. The spray volume can be precisely adjusted according to the amount of dust. When the dust is heavy, the flow rate can be increased to enhance dust suppression, and when the dust is light, the flow rate can be reduced to save water resources. Different slots, together with the adjustment plate 75, can form water mist of different densities, which can specifically suppress dust of different particle sizes. This flexibly adapts to changes in the working conditions of the conveyor 1, such as changes in material type and conveying speed that cause changes in dust, and always maintains effective dust suppression.

[0041] When the lever 76 rotates towards the side closer to the inclined bar 84, it drives the squeezing rod 81 to rotate towards the side closer to the inclined bar 84, causing the squeezing rod 81 to squeeze the inclined bar 84, resulting in displacement of the inclined bar 84. This displacement of the inclined bar 84 drives the turntable 83 to rotate, causing the turntable 83 to move the vibrating rod 85 towards the side closer to the outer wall of the nozzle 71. The vibrating rod 85 strikes the outer wall of the nozzle 71, causing the nozzle 71 to vibrate and clear the large slot 73 and small slot 74, preventing blockage. When the inclined bar 84 is no longer squeezed, it will automatically reset through the torsion spring 86. Vibration clears the slots of the nozzle 71, preventing blockage and ensuring continuous and effective dust suppression. The automatic reset structure ensures that the vibration device can work repeatedly without frequent manual maintenance, providing continuous and stable spray protection and improving the overall reliability and dust suppression efficiency of the dust suppression device on the conveyor 1.
