Description

Technical Field

[0001] The utility model relates to the technical field of dry fog dust suppression, in particular to a micron-level dry fog dust suppression device. Background Art

[0002] Dry mist dust suppression uses compressed air to drive an acoustic oscillator. The sonic boom of high-frequency sound waves atomizes water in the nozzle's resonant chamber, producing fine dry mist particles smaller than 10μm (water mist particles larger than 2.5μm and smaller than 10μm are called dry mist). These particles are sprayed toward the dust source, where they collide and bond with dust particles, agglomerating and growing before settling under gravity, effectively reducing dust. Existing dry mist dust suppression devices typically include an electrical control cabinet, a dry mist main unit, a spray box, a filtration system, and a pressurization system. The generated dry mist is ultimately ejected through the spray box. Existing spray boxes are typically constructed from a single box with several spray heads, connectors, and pipelines installed. However, the fixed specifications of the spray box, including size, number of spray heads, and spacing between the heads, limit the range of dry mist dust suppression, making it difficult to adapt to the dust suppression requirements of varying environments or dust levels. Utility Model Content

[0003] Based on this, it is necessary to provide a micron-level dry mist dust suppression device to address the problem that the specifications of existing spray boxes are fixed, which makes the range of dry mist dust suppression relatively fixed, making it difficult to adapt to dust suppression requirements in different environments or with different dust levels.

[0004] A micron-level dry mist dust suppression device comprises a spray box comprising at least two spray units and at least one extension piece;

[0005] The spray unit includes a housing and a spray head; the housing is configured in the shape of a quadrangular prism; two symmetrical sides of the housing are provided with symmetrical connecting grooves; the other two symmetrical sides of the housing are connected to connecting pieces parallel to the connecting grooves; the connecting pieces and the connecting grooves match each other; the spray head is connected to the interior of the housing and is used to spray micron-level dry mist outside the housing;

[0006] Both ends of the extension piece match the connecting grooves, and are used to connect adjacent spray units into a whole.

[0007] As a preferred example, the lengths of the connecting groove and the connecting member are the same as the length of the housing.

[0008] As a preferred example, the lengths of the connecting groove and the connecting piece are smaller than the length of the shell, and one end of the connecting groove is located at the edge of the shell.

[0009] As a preferred example, the cross-sectional shapes of the connecting groove and the connecting piece are both set to be T-shaped.

[0010] As a preferred example, the extension piece includes an extension plate and two embedded plates; the two embedded plates are respectively connected to the two ends of the extension plate, and the whole is in an I-shape; the embedded plates match the connecting grooves.

[0011] As a preferred example, a plurality of fixing holes are provided on both of the embedded plates.

[0012] As a preferred example, one side of the connecting groove on the shell in the length direction is provided with an outlet of the spray head, and the other side is connected to a pipe communicating with the spray head.

[0013] As a preferred example, the plurality of spray units are combined in a straight line or in a matrix.

[0014] As a preferred example, adjacent shells are connected to form a whole through connecting grooves and connecting pieces.

[0015] As a preferred example, the micron-level dry mist dust suppression device further includes a distribution box, which is used to detachably connect multiple spray heads and provide dry mist to the spray heads.

[0016] The beneficial effect of the present invention lies in that, through the modular configuration of the spray box, the present invention enables the spray box to be composed of any number of spray units or any number of spray units and extension plates. The specifications and dimensions of the freely combinable spray box are adjustable, thereby adjusting the range of dry mist dust suppression. According to the dust suppression requirements under different environments or different dust levels, whether it is a large-scale dust suppression scenario or a small-scale dust suppression scenario, a matching spray box can be quickly assembled to adapt to the on-site working environment.

[0025] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0026] 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.

[0027] Please refer to Figure 1 This embodiment provides a micron-level dry mist dust suppression device, which includes an electric control cabinet, a dry mist main unit, a spray box, a filtration system, a pressurization system, a water supply system, an air supply system and other components. The utility model redesigns the spray box, and the remaining components adopt the existing technology. The spray box includes two spray units and two extensions. The spray unit includes a shell 1 and a spray head 2. The shape of the shell 1 is set to be a quadrangular prism. For the convenience of explanation, Figure 1The A side is called the front side, the B side is called the right side, and the corresponding other sides are respectively the top, bottom, left side and back side. Symmetrical connecting grooves are provided on the left and right sides of the shell 1. Symmetrical connecting parts 3 are provided on the top and bottom of the shell 1. The length of the connecting part 3 and the connecting groove is the same as the length of the shell 1, extending to both ends of the shell 1 (that is, extending to the front and back). The connecting part 3 is arranged in parallel with the connecting groove, that is, the connecting part 3 and the connecting groove are arranged in one direction to facilitate subsequent installation. Specifically, the cross-sectional shape of the connecting part 3 and the connecting groove is set to T-shaped. The spray head 2 adopts the existing micron-level dry mist spray head 2. The spray head 2 is installed inside the shell 1, and the outlet of the spray head 2 is set in front of the shell 1. A pipe connected to the spray head 2 is also connected to the back of the shell 1. The pipe is connected to the front-end equipment of the dry mist dust suppression device, and finally the dry mist is sprayed out through the spray head 2. In addition, the cross-sectional shape of the connecting member 3 and the connecting groove is not limited to T-shaped, and can be set to other shapes that can be embedded and prevented from falling off, such as a dovetail shape, a circle, etc.

[0028] The extension piece includes an extension plate 4 and two embedded plates 5. The two embedded plates 5 are respectively connected to the two ends of the extension plate 4, and the whole is in an I-shape. The I-shaped extension piece can match the connection groove on the shell 1. Figure 1 As shown, the two ends of the extension piece are respectively connected to the two shells 1, so that the two spray units form a whole. At the same time, multiple fixing holes can be opened on the embedded plate 5. After the extension piece is installed on the shell 1 at the edge, the idle embedded plate 5 on the other side can be fixedly connected to the external fixing parts or the frame through the fixing holes thereon, so that the entire spray box is fixedly installed. Furthermore, a limiting hole is also opened on the side of the shell 1 where the connecting groove is opened. The limiting hole corresponds to the fixing hole on the embedded plate 5 inserted into the connecting groove. Limiting pins or limiting screws are inserted into the limiting hole and the corresponding fixing hole to prevent the embedded plate 5 from falling out of the connecting groove and strengthen the connection strength between adjacent spray units.

[0029] In another embodiment, Figure 2As shown, compared with the above embodiment, the difference is that the length of the connecting groove and the connecting member 3 is different. In this embodiment, the length of the connecting groove and the connecting member 3 does not need to extend to the length of the shell 1, ensuring that one end of the connecting groove is located at the edge of the shell 1. At this time, the length of the connecting groove and the connecting member 3 can be set to be less than the length of the shell 1, ensuring that there is sufficient friction between the connecting member 3 and the connecting groove, which can ensure the combined assembly of the spray unit, thereby helping to reduce materials. In another embodiment, the micron-level dry mist dust suppression device also includes a distribution box. A one-to-many pipeline is provided in the distribution box, that is, one inlet and multiple outlets. The inlet of the pipeline is connected to the front-end equipment of the dry mist dust suppression device. The outlet of each pipeline is provided with a valve. The pipes at the tail of the multiple spray heads 2 correspond one-to-one to the outlets of the multiple pipelines, and quick connection is achieved through threaded joints, thereby realizing the pipeline connection of the modularly arranged spray unit.

[0030] Select the appropriate number of spray units according to the site environment or actual working conditions. Multiple spray units can have different installation methods and installation structures. When installing, such as Figure 3 As shown, multiple spray units can be arranged in a straight line. Each spray unit is connected by an extension piece to control the spacing between adjacent spray units. In another embodiment, as shown Figure 4 As shown, compared with the above installation method, the extension piece can be used directly by using the connection groove and the connection piece 3 on the shell 1, and the T-shaped connection piece 3 is slid into the T-shaped connection groove for connection. In the above two assembly methods, no matter which method is used, in addition to the straight-line setting, in order to increase the dry mist spraying volume, multiple spray units can also be combined in a matrix. Figure 5 As shown, multiple spray units can be arranged in a matrix of multiple rows and columns to increase the spray volume per unit area on site. The required dust suppression requirements can be met by increasing or decreasing the number of spray units according to the site environment or actual working conditions.

[0031] 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.

[0032] 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.
