A gas-liquid two-phase flushing nozzle and sanitation vehicle

Abstract

The invention discloses a gas-liquid two-phase flushing suction nozzle and a sanitation vehicle, comprising a suction nozzle body, a suction pipe and a high-pressure spray gun welded on the upper surface of the suction nozzle body, and a forward spray nozzle is installed on the lower side of the high-pressure spray gun along its axial interval. A high-pressure nozzle, an air intake duct is arranged between the suction pipe and the high-pressure spray gun, the upper end of the air intake duct is welded with an air intake duct, and the lower end passes through the nozzle body and extends into the cavity of the nozzle body. A vertical wear-resistant block is arranged between the suction pipe and the air intake duct, the top of the wear-resistant block is connected to the nozzle body, there is a gap between the bottom end and the ground, and the rear edge of the wear-resistant block It is connected with the front bottom end of the air intake duct. The protruding end of the air intake duct is flat and inclined towards the front, the cross section of the protruding end gradually becomes smaller along the outlet direction, and the width of the protruding end is consistent with the suction width of the suction nozzle. Compared with the prior art, the invention flushes the garbage through the high-speed air curtain and the water curtain, which can reduce the water consumption and improve the cleaning rate and operation stability.

Description

technical field [0001] The invention belongs to a suction nozzle structure for sanitation vehicles, in particular to a gas-liquid two-phase flushing suction nozzle and a sanitation vehicle, which are applied to sanitation vehicles or equipment for road cleaning. Background technique [0002] With the rapid development of urban and rural construction, the scope of urban roads, suburban roads and township roads has continued to expand. As people have higher and higher requirements for environmental cleanliness, the corresponding road cleaning pressure and workload are also increasing. In order to achieve efficient and fast cleaning operations and reduce labor costs, the demand for sanitation vehicles and equipment for road cleaning is growing rapidly. The industry has also continuously introduced various sanitation sweeper products with diverse functions and stable performance according to the needs of the market and customers. How to improve the operation effect of sanitation...

AI Technical Summary

Problems solved by technology

However, this cleaning operation mode also has the following problems: 1) It needs to consume a lot of water, which is not suitable for cities in the north where there is a drought and water shortage. The water after washing the ground will be sucked into the suction nozzle like garbage, which becomes a suction burden ;2) In order to hold more clean water, the volume of the garbage bin is affected; 3) After the operation, there is a lot of residual water on the ground, which cannot be used in winter, and the ground is frozen; 4) When the high-pressure nozzle is blocked, the effect of cleaning operation will decrease obvious
