Description

Technical Field

[0001] The utility model relates to the technical field of dry fog dust suppression, in particular to a high-pressure spray dust suppression system. Background Art

[0002] In the raw material handling systems of factories in industries such as building materials, metallurgy, and mining, raw materials and batch materials are typically transported and transferred using belt conveyors. While belt conveyors offer many advantages, such as long conveying distances, high throughput, and minimal maintenance, they also have drawbacks. When conveying powdery materials (such as cullet, coal dust, silica sand, slurry, and glass batch), most of these materials generate significant dust on the conveyor belt working surface. To facilitate material transfer, high-pressure spray dust suppression systems are often installed at various locations along the belt conveyor. These systems consist of a material trough and a dry mist spray device. The trough is wrapped around the conveyor at the corresponding location to prevent material spillage, while the dry mist spray device is positioned within the trough to suppress dust. While this dust suppression system is effective, it has some drawbacks. For example, to ensure sufficient dry mist coverage, at least three spray heads with different spray directions are installed within the dust suppression position within the trough. Each spray head requires its own dry mist piping, which complicates the layout of the spray heads and their associated piping, making installation and subsequent maintenance difficult. Utility Model Content

[0003] Based on this, it is necessary to provide a high-pressure spray dust suppression system to address the problem that the existing spray dust suppression system is equipped with at least three spray heads with different spray directions and their corresponding pipelines, which makes the layout of the spray heads and their pipelines relatively complicated and not conducive to installation and subsequent maintenance.

[0004] A high-pressure spray dust suppression system includes a material guide chute and at least one spray module; the material guide chute includes a sealing shield; the spray module includes:

[0005] a housing mounted on top of the sealing shield;

[0006] The spray pipe includes a fixed pipe and a rotating pipe; the fixed pipe is connected to the housing, and one end of the fixed pipe extends into the housing and is rotatably sleeved with the rotating pipe; the rotating pipe is rotatably mounted on the housing; the end of the rotating pipe away from the fixed pipe passes through the sealing shield and extends to the inner top of the sealing shield;

[0007] A driving mechanism, which is provided on the housing and is used to drive the rotating tube to rotate;

[0008] The spray head is connected to one end of the rotating tube located in the material guide trough; the spray head is communicated with the rotating tube and is used for spraying dry mist while rotating with the rotating tube.

[0009] As a preferred example, the driving mechanism includes a driving gear, a driven gear and a motor; the driven gear is fixedly sleeved with one end of the rotating tube located in the shell; the motor is connected to the shell, and the output shaft of the motor is fixedly sleeved with the driving gear; the driving gear is meshed with the driven gear.

[0010] As a preferred example, a baffle is fixedly sleeved on one end of the rotating tube located in the shell, and a limiting groove with the rotating tube as the center is opened on one side of the baffle, and multiple balls are rolled in the limiting groove; the multiple balls are rollingly connected to the inner bottom of the shell.

[0011] As a preferred example, a rotating sealing ring is provided between the fixed tube and the rotating tube.

[0012] As a preferred example, the spraying direction of the spray head is set to be a horizontal direction, or the angle between the spraying direction of the spray head and the vertical direction is an acute angle.

[0013] As a preferred example, the spray module further includes an additional spray head; the additional spray head is arranged at one end of the rotating tube located in the sealing shield, and the spray direction of the spray head is set to vertically downward.

[0014] As a preferred example, one end of the fixed tube away from the rotating tube extends to the outside of the shell and is provided with a quick connector.

[0015] As a preferred example, at least three spray modules are provided, and the plurality of spray modules are evenly spaced apart in the length direction of the sealing shield.

[0016] As a preferred example, both ends of the sealing shield in the length direction are provided with dust curtains, which are used to isolate the dust in the material guide chute.

[0017] As a preferred example, an observation window cover is provided above the sealing shield.

[0018] The beneficial effect of this utility model is that, by arranging multiple spray modules, only one spray head is required to achieve 360-degree dry mist coverage over a wide area through rotation. In a long material guide trough, a spray module can be arranged at intervals, and each spray module can spray dry mist covering the area and in multiple directions. Compared with the traditional arrangement of multiple spray heads in multiple directions, this utility model can significantly reduce the number of spray heads and their corresponding pipelines, facilitating installation and subsequent maintenance and replacement.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please refer to Figure 1 This embodiment provides a high-pressure spray dust suppression system, which includes a guide trough and several spray modules. The main part of the guide trough includes a sealing shield 1, which is wrapped around the roller group and the belt ( Figure 1Only the upper roller group and belt are shown, and the lower roller group and belt are not shown. Since the lower roller group and belt do not transport materials, they can be set inside or outside the sealing shield 1). The feed port of the sealing shield 1 can be set at the top or at one end. At the same time, dust curtains 11 are provided at both ends of the sealing shield 1, namely the feed port and the discharge port, to prevent internal dust and airflow from leaking out of the feed port and the discharge port. The top of the sealing shield 1 is set in a trapezoidal shape. An observation window is provided on the inclined surface of the top of the sealing shield 1, and a transparent observation window cover 12 is provided to facilitate observation of the environment and conditions inside the sealing shield 1.

[0027] The spray module is installed on the top of the sealing shield 1. According to the length of the sealing shield 1 and the dust suppression requirements, a corresponding number of spray modules are arranged. If the number of spray modules is large, they are evenly spaced along the length direction of the sealing shield 1. Specifically, Figure 2As shown, the spray module includes a housing 2, a spray pipeline, a drive mechanism, and a spray head 5. The housing 2 is fixedly mounted on the top of the sealing shield 1. The spray pipeline includes a fixed tube 3 and a rotating tube 4. The fixed tube 3 is also fixed to the housing 2, with the bottom end of the fixed tube 3 located inside the housing 2 and the top located outside the housing 2. At the same time, a quick connector 10, such as a sealed threaded connector, is fixedly connected to the top of the fixed tube 3 for quickly connecting the pipeline to the front-end equipment that generates dry mist. The bottom end of the fixed tube 3 is rotatably connected to the top of the rotating tube 4. Generally, the fixed tube 3 is located inside the rotating tube 4, and a rotating sealing ring is provided at the rotating contact point between the fixed tube 3 and the rotating tube 4 to enhance the sealing between the fixed tube 3 and the rotating tube 4. The bottom of the rotating tube 4 extends outside the housing 2 and passes through the top of the sealing shield 1, so that the bottom of the rotating tube 4 extends to the inner top area of ​​the sealing shield 1. The spray head 5 is horizontally mounted at the bottom of the rotating tube 4, that is, the spray head 5 is located inside the sealing shield 1 and above the belt. As the rotating tube 4 rotates the spray head 5, dry mist enters the spray head 5 through the spray line and is sprayed into the sealed shield 1. A single spray head 5 can now achieve 360-degree dry mist coverage. To enable the rotating tube 4 to rotate, in this embodiment, the drive mechanism includes a driving gear 6, a driven gear 7, and a motor 8. Since it only needs to drive the rotating tube 4 and a small number of spray heads 5 to rotate, the power and size of the motor 8 can be relatively small, allowing it to be installed inside or outside the housing 2. The top of the rotating tube 4, located at one end of the housing 2, is fixedly connected to the driven gear 7. The driving gear 6 and the driven gear 7 mesh together to form a gear train located inside the housing 2 to protect it from external impurities such as dust. The output shaft of the motor 8 is fixedly connected to the driving gear 6, thereby driving the rotating tube 4 to rotate. Furthermore, the housing 2 has a through hole with the same diameter as the rotating tube 4. The rotating tube 4 is inserted into the through hole, and the portion of the rotating tube 4 located inside the housing 2 is fixedly connected to a baffle 9. The bottom of the baffle 9 is provided with an annular limiting groove centered on the rotating tube 4. Multiple balls are rolled within the limiting groove. These balls are in rolling contact with the inner bottom of the housing 2, thereby reducing friction and supporting the rotating tube 4.

[0028] In one embodiment, the spray direction of the spray head 5 is set to be inclined, that is, the angle between the spray direction of the spray head 5 and the vertical direction is an acute angle, and the spray head 5 sprays obliquely downward to prevent insufficient dry mist below the rotating tube 4. In another embodiment, the spray module can also add an additional spray head 5. The original spray head 5 is still set in the horizontal direction to maximize the coverage of the dry mist spray. The additional spray head 5 is fixedly connected to the bottom of the rotating tube 4, and the spray direction is set vertically downward. This arrangement does not require the addition of additional pipelines. One rotating tube 4 can supply two spray heads 5 to spray dry mist, and the spray range is larger. In a longer material guide trough, a spray module can be arranged at a certain distance. The spray module can spray dry mist covering the area and in multiple directions. Compared with the traditional multi-directional arrangement of multiple spray heads 5, this high-pressure spray dust suppression system can significantly reduce the number of spray heads 5 and their corresponding pipelines, which is convenient for installation and subsequent maintenance and replacement.

[0029] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
