Sanitation vehicle and secondary pressurizing suction and spraying device and spray gun thereof

Abstract

The invention relates to a sanitation vehicle and a secondary pressurizing suction and spraying device and a spray gun thereof. The spray gun comprises a spray gun body of a cylindrical structure. Oneend of the spray gun body is provided with a jet orifice, and the other end of the spray gun body is provided with an air inlet which forms a relay air port of an exhaust outlet of a suction fan. Thespray gun body is internally provided with an air pressurizing device for re-pressurizing high-pressure air entering the gun spray body from the air inlet. The air flow path on the spray gun body isprovided with an air supplementing opening which is located at the upstream of the air pressurizing device. The spray gun body further includes an atomizing device located at the jet orifice of the spray gun body. The mist discharge position of the atomizing device is within the outer contour of an air outlet column of the spray gun body, the air pressurizing device increases the pressure and speed of the high-pressure air again, and thus the spray gun shoots farther. In order to meet the injection volume of the high-pressure air, the air supply in the spray gun body can be realized through the air supplementing opening, and sufficient air supply can be ensured in the spray gun body.

Description

technical field [0001] The invention relates to a sanitation vehicle, a secondary pressurized suction spray device, and a spray cannon body. Background technique [0002] It is well known that road cleaning and cleaning vehicles are used to clean the road surface of urban roads, so that the roads can be in a good state of use, thereby ensuring the normal operation of urban roads. The mechanical cleaning has been developed to the existing cleaning modes, among which the high efficiency is the pneumatic road sweeper which uses air flow to collect and store dust and garbage, which can effectively reduce dust pollution, improve air quality, and reduce The content of inhalable particulate matter in the air, so as to achieve the purpose of improving the living environment of urban residents. [0003] As disclosed in the Chinese patent document CN206090418U with the authorized announcement number, a multifunctional cleaning vehicle for road surface maintenance is disclosed, which ...
