technical field

The invention relates to the technical field of road cleaning vehicles, in particular to a cleaning vehicle based on centrifugal water curtain dust removal technology.

Background technique

Fuel oil version or electric version road sweeper cleaning machine of prior art all is the cleaning special equipment that collects cleaning, dust suction at present. Most of its structure adopts: the side brush collects the road garbage in the cleaning width range to the working range of the main brush, and the main brush rotates in the brush cylinder to raise and throw the garbage entering the brush cylinder to the garbage bin on the vehicle, or the fan rotates to generate airflow The garbage is sucked into the garbage bin; the airflow during the working process of the fan will cause the dust in the garbage to move with the airflow of the fan, which will generate working dust and cause secondary pollution; most of the existing dust blocking methods are to install air filters in the air duct or at the air outlet. It is carried out in the form of a dust filter bag; the device has the following deficiencies: 1. Due to the different working conditions of the road surface of the cleaning operation, there is a lot of dust on the road surface, and when the continuous working time is long, there will often be too much dust to block the filter element and filter bag. 2. The dust-vibrating mechanism of the filter element and filter bag is complicated, inconvenient to operate, and needs to be replaced regularly, which increases the cost of operation and maintenance; 3. Due to the need to ensure the permeability of the filter element and filter bag, so The mesh number of the filter element and filter bag should be set moderately. If the airflow is too dense, it will not pass through, and if it is too thin, a large amount of tiny dust will pass through, causing the emission of the sweeper to exceed the standard; Installing a spray dust-reducing water nozzle makes it difficult to control the amount of water sprayed. If the amount of water sprayed is too small, the expected effect of dust suppression and dust suppression will not be achieved. If the amount of water sprayed is too large, the garbage mixed with water mist will enter the brush cylinder and the air flow channel. It will cause the filter element and filter bag to be clogged with water mist and ash due to excessive humidity, resulting in the inability to carry out the cleaning operation smoothly and efficiently.
