A high-pressure dedusting fog cannon

Abstract

The invention relates to a high-pressure dedusting fog machine, which includes a water storage tank and a water pump. The water pump is arranged in an installation cavity. The upper end of the drain pipe extends beyond the upper end of the water storage tank, and the upper end of the drain pipe is connected with an extension pipe through a flange. The extension tube is connected with a spray gun; the upper end of the water storage tank is provided with a support frame with a limited extension tube. The support frame includes a frame body 1 and a frame body 2 arranged parallel to each other, and the frame body 1 and frame body 2 are connected through a connecting rod. , the extension tube is limited on the frame body two, and the side of the frame body one away from the frame body two is rotationally connected to the water storage tank. For the limit rod in the limit groove, the frame body 2 is also provided with a driving member that drives the vertical displacement of the limit rod. The invention has the effects of increasing the spraying height and spraying range of the water mist and reducing the number of fog cannons required for dust reduction on construction sites, so as to ensure the dust reduction work and reduce the impact on building construction.

Description

technical field [0001] The invention relates to the technical field of dust reduction on construction sites, in particular to a high-pressure dust removal fog cannon. Background technique [0002] At present, with the continuous expansion of the city scale and the gradual increase of various construction projects, the adverse impact of the construction industry on the urban environment is becoming more and more serious; in order to further improve the urban living environment, each urban area organizes various functional departments to increase Supervise demolition projects and construction excavation sites that may cause dust pollution, and force construction units to take dust prevention and reduction measures. At present, most construction sites use fog cannons for dust suppression. [0003] The existing authorization announcement number is that the Chinese patent of CN207331584U discloses a kind of laterally moving fog cannon machine, including frame, gun barrel, gun mo...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: due to the limited height of the fog cannon, the barrel is generally in an inclined spray mode, so that when it sprays water mist, it is an arc spray range from low to high and then low, resulting in its spraying The height range is limited, generally 1-4 meters, and the length of spraying is 6-8 meters at the same time, and the construction site is large, so when it wants to achieve a better dust reduction effect, it can only be equipped with multiple fog cannons for water mist Dust reduction work; at the same time, due to the low height of the gun barrel, when the water mist is sprayed from the opening of the gun barrel, it is easy to be blocked by construction equipment, buildings or staff on the construction site. On the one hand, it affects the dust reduction work, and on the other hand construction work
