Description

Technical Field

[0001] This utility model relates to the field of dry fog dust suppression technology, and in particular to a micron-level dry fog constant pressure dust suppression device. Background Technology

[0002] Dry fog dust suppression technology is a highly efficient and environmentally friendly dust control method, widely used in work environments prone to dust and floating ash. This technology utilizes specially designed nozzles to atomize water into extremely small micron-sized particles, creating a suspended state in the air similar to natural fog. These ultrafine droplets can fully contact airborne dust particles, exhibiting excellent capture effects, particularly for inhalable dust particles with diameters below micron. After the water mist particles combine with the dust, they agglomerate into larger particles, which then settle under gravity, effectively reducing the concentration of dust and floating ash in the air and achieving highly efficient dust suppression.

[0003] Dry fog dust suppression nozzles rely on high-pressure water flow for propulsion during spraying operations. The water flow has a strong impact force, so they are typically fixed directly to the connector using threaded fasteners to ensure stability. However, during prolonged high-intensity operation, the nozzles are subjected to continuous water flow and vibration, which can easily cause wear and tear, leading to a decline in sealing performance. Weakened sealing increases the risk of leakage at the connection points, affecting not only the dust suppression effect but also potentially wasting water resources, thus shortening the overall service life and increasing maintenance costs. Utility Model Content

[0004] The technical problem this invention aims to solve is that dry fog dust suppression nozzles operate at high frequencies for extended periods, leading to wear at the connection points and reduced airtightness.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a micron-level dry fog constant pressure dust suppression device, including a nozzle body and a protective shell, wherein the protective shell has a cavity through which it is opened, the nozzle body is configured as a cylindrical nozzle and placed in the cavity of the protective shell, and the nozzle body is fixedly connected to the protective shell, a connecting platform is fixedly provided on the top of the protective shell, the connecting platform has an inner cavity through which it communicates with the cavity, a first thread is provided on the outer wall of the top of the connecting platform, a second thread is provided on the connecting port of the top of the nozzle body, and a first sealing ring and a second sealing ring are provided on the outer side of the first thread and the second thread.

[0006] As a further improvement of this utility model, the output end of the nozzle body is located at the bottom, and multiple square grooves are provided through the corresponding part of the protective shell.

[0007] As a further improvement of this utility model, the square groove and the inner wall of the bottom side of the protective shell are coated with a ceramic coating.

[0008] As a further improvement of this utility model, an annular groove is provided at the top of the connecting platform, and the annular groove is fastened and engaged with the first sealing ring.

[0009] As a further improvement of this utility model, the second sealing ring is securely fitted on the top of the nozzle body and abuts against the top of the connecting platform.

[0010] As a further improvement of this utility model, four connecting arms are fixedly provided on the outer wall of the nozzle body, and the connecting arms are fixedly connected to the inner wall of the cavity of the protective shell.

[0011] The beneficial effects of this utility model are as follows: By combining the protective shell with the nozzle body in a fixed manner, this utility model enhances the structural stability of the product. Simultaneously, a first thread and a second thread are respectively provided on the top of the protective shell and the nozzle body. This double-threaded fixing design effectively prevents high-pressure water flow from impacting the connection, thus preventing the nozzle from loosening, increasing wear, and improving the reliability of the fastening. Furthermore, a first sealing ring and a second sealing ring are added between the nozzle and the connection point, improving airtightness and reducing the direct force of water flow impact on the nozzle, thereby reducing the wear rate. Finally, the bottom side of the protective shell and the inner wall of the square groove are coated with a ceramic coating, which reduces localized impact force and minimizes excessive localized wear on the nozzle.
