Description

Technical Field

[0001] This utility model relates to a centrifugal spray device with a large spray angle, belonging to the technical field of textile air conditioning spray system. Background Technology

[0002] Existing textile air conditioning spray systems using centrifugal nozzles have several problems. Centrifugal nozzles have a small spray angle, generally 90° or less, resulting in limited spray coverage and insufficient heat and moisture exchange. Impact nozzles have a spray angle of 180° and a large spray coverage, but the liquid breaks up unevenly after collision, resulting in a wide range of droplet sizes. Many droplets are too large or too small, leading to poor atomization. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a centrifugal spraying device with a large spray angle, which increases the spray angle, expands the spray range, ensures the atomization effect, and improves the heat and moisture exchange efficiency, in contrast to the above-mentioned prior art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a centrifugal spraying device with a large spray angle, including a spray housing, one end of which is open, and a spray cover is provided at the open end of the spray housing. The spray cover and the spray housing are threaded together. A spray nozzle is opened in the center of the spray cover. A diffuser cone is passed through the spray nozzle. A spiral groove is opened in the inner wall of the spray housing. The spray housing is connected to a spray pipe. The spray pipe is connected to the inner cavity of the spray housing. The water flow in the spray pipe flows into the inner cavity of the spray housing. The water flow flows spirally along the spiral groove and then is sprayed out through the spray nozzle and impacts the bottom of the diffuser cone to form a large-angle spray water mist.

[0005] The injection nozzle has a tapered structure that is wider at the top and narrower at the bottom.

[0006] The bottom of the inner cavity of the spray housing is provided with a boss, and a threaded hole is opened in the center of the boss. The bottom of the diffuser cone is provided with a threaded hole, and the two are threadedly connected.

[0007] A sealing ring is provided between the spray housing and the spray cover.

[0008] Compared with existing technologies, the advantages of this utility model are as follows: A centrifugal spray device with a large spray angle features a spiral water flow where water collides with each other within the vortex chamber, preventing a decrease in water flow velocity. The diffuser cone has a taper of 150°, and the spiral water flow within the vortex chamber is ejected through the spray nozzle and impacts the cone's conical part, forming a large-angle spray mist that expands the spray coverage area. Adjusting the distance between the diffuser cone's conical part and the spray nozzle optimizes the water spray effect and improves atomization performance, thereby enhancing the heat and moisture exchange efficiency of the air conditioning spray system and creating a more stable and suitable environment for textile production.

Detailed Implementation

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0011] like Figure 1 , 2 As shown in Figure 3, a centrifugal spraying device with a large spray angle in this embodiment includes a spray housing 1, which is open at one end and closed at the other. A spray cover 4 is installed at the open end of the spray housing 1, and the spray cover 4 is threadedly connected to the spray housing 1, making assembly and disassembly convenient. A tapered spray nozzle 8, wider at the top and narrower at the bottom, is opened at the center of the spray cover 4. A diffuser cone 5 vertically passes through the spray nozzle 8, and the bottom of the diffuser cone 5 has external threads. A boss 7 is provided at the bottom of the inner cavity of the spray housing 1, with a threaded hole at its center. The bottom of the diffuser cone 5 also has a threaded hole, and the two are threadedly connected. This allows for easy assembly and disassembly of the diffuser cone and makes its vertical position adjustable. A spray pipe 6 is connected to the spray housing 1, and the inner cavity of the spray pipe 6 communicates with the inner cavity of the spray housing 1. A spiral groove 2 is opened on the inner wall of the spray housing, forming a vortex chamber within the spray housing. Water from the spray pipe 6 flows into the vortex chamber, where it flows in a spiral pattern. The water flow within the vortex chamber collides with each other, preventing a decrease in water flow velocity. The diffuser cone has a taper a of 150°. The spiral water flow in the vortex chamber is ejected through the nozzle and impacts the cone of the diffuser cone, forming a large-angle spray mist that expands the spray coverage area.

[0012] A sealing ring 3 is provided at the connection between the spray housing 1 and the spray cover 4 to seal the connection.

[0013] By adjusting the depth of the threaded hole at the bottom of the diffuser cone, the distance between the cone and the spray nozzle can be adjusted, thereby optimizing the water spray effect, improving atomization performance, and thus improving the heat and moisture exchange efficiency of the air conditioning spray system, creating a more stable and suitable environment for textile production.
