Pneumatic sweeping and conveying system of road sweeper

Abstract

A pneumatic sweeping and conveying system of a road sweeper is composed of a high-pressure air blower, an air supply passage, an air amplifier, a dust suction opening, a conveying pipe, a dust suction opening fixing support and an air supply pipe fixing sleeve. The high-pressure air blower is connected with the air amplifier through the air supply passage. The air amplifier is connected to the position above the dust suction opening. The conveying pipe is arranged above the air amplifier. The dust suction opening is fixed through the dust suction opening fixing support. The air supply pipe is fixed through the air supply pipe fixing sleeve. The air supply passage is provided with at least two branches. The air supply passage is formed by a straight air supply pipe a, a straight air supply pipe b, a straight connecting pipe, a cavel-shaped tee joint, a reversing air supply pipe a, a reversing air supply pipe b, a reducing pipe and a straight joint. The pneumatic sweeping and conveying system has the advantages that air entering a draught fan is natural air and does not need to be filtered, therefore, the pneumatic sweeping and conveying system is simplified, pressure losses are reduced, and the work efficiency of the draught fan is improved; the pneumatic sweeping and conveying system is simple in structure, low in pressure loss and energy consumption and environmentally friendly, and saving energy.

Description

technical field [0001] The invention relates to the field of road cleaning equipment, in particular to a road sweeper pneumatic cleaning and conveying system. Background technique [0002] At present, road sweepers can be basically divided into three types: pure sweeping type, pure suction type and suction sweeping type according to different operating methods; The pure suction road sweeper uses the induced air of the fan to achieve cleaning, and the introduced air is used as a carrier to bring the cleaning objects into the air. The pneumatic conveying channel needs to be equipped with a settling box and a filter to settle and filter the finer particles of garbage and dust, respectively. Dust, the introduced air is filtered and finally discharged from the fan; the pneumatic conveying system of the suction sweeper is similar to that of the pure suction sweeper, the difference is that the cleaning device is also equipped with a sweeping brush, which is composed of the sweeping...

[0002] At present, road sweepers can be basically divided into three types: pure sweeping type, pure suction type and suction sweeping type according to different operating methods; The pure suction road sweeper uses the induced air of the fan to achieve cleaning, and the introduced air is used as a carrier to bring the cleaning objects into the air. The pneumatic conveying channel needs to be equipped with a settling box and a filter to settle and filter the finer particles of garbage and dust, respectively. Dust, the introduced air is filtered and finally discharged from the fan; the pneumatic conveying system of the suction sweeper is similar to that of the pure suction sweeper, the difference is that the cleaning device is also equipped with a sweeping brush, which is composed of the sweeping brush and the pneumatic conveying system Realize cleaning operations; in order to provide sufficient suction for pure suction and suction sweeping road sweepers, the fan equipped with them consumes a lot of energy, is expensive to use, and is not environmentally friendly. Moreover, secondary dust is still generated during operation
