Description

A circulating water utilization road sweeper with multi-stage cleaning function

technical field

The utility model relates to the technical field of road sweepers, in particular to a road sweeper with multi-stage cleaning function utilizing circulating water.

Background technique

With the development of my country's economy and the needs of urbanization construction, mechanized cleaning of urban roads has been basically popularized. At present, there are three types of urban road sweepers on the market: ①, pure sweeping type; ②, sweeping suction type; ③ , Pure suction type.

The pure-sweeping road sweeper does not use fan suction, but only relies on side sweeping brushes and roller brushes to sweep up the garbage and drop it into the garbage bin. The work efficiency is low, and it is easy to raise dust. be widely promoted.

Sweeping suction road sweeping vehicles are mostly equipped with four brushes in the middle and a rear suction cup structure. During the cleaning process, wet dust control is carried out by spraying clean water. Dust spraying and dusting are common at times, causing secondary pollution. Because the work requires water, the driving distance of the vehicle is limited by the size of the water tank.

Wet dust control device: brush + water spray, complex mechanism, high manufacturing cost, many wearing parts, high energy consumption. The sprayed water will easily form a thin ice layer on the road surface, which will easily cause pedestrians to fall or vehicles to skid, causing unsafe hidden dangers in urban traffic. The garbage is sucked into the garbage bin and freezes due to moisture, so that the garbage cannot be dumped from the bin. If the deicing agent aqueous solution is used to spray water, it will pollute the road, seriously affect the growth of greenery, and pollute the environment. Therefore, this type of road sweeper cannot be commonly used in the northern region and in winter and dusty areas.

The structure of the pure suction road sweeper is to cancel the sweeping brush, and use a high-power fan to clean the garbage on the road surface through the movable suction nozzle or the fixed suction nozzle. This working principle is similar to that of a household vacuum cleaner. At present, the pure suction road sweeper technology also has certain defects. Since the road sweeper does not need sweeping brushes, the suction of a fan is limited, and it is equipped with two suction nozzles that move with the car. 1. Dust, leaves, paper scraps and heavy particle garbage that adhere to the ground after raining are not easy to be sucked up. In order to solve the problem of spraying dust and flying dust, bag-type or filter paper-type devices are often used to filter the dust-laden airflow. However, due to complex road conditions, wet dust often passes through the cloth bag or filter paper device in case of rainy and snowy weather or road surface water, causing blockage of cloth holes or filter paper pores, increasing the operating resistance of the fan, reducing suction, and seriously reducing the quality of cleaning operations. . In order to ensure the quality of the operation, the filter device needs to be replaced and cleaned frequently in time, which increases the labor intensity of the operator, and the recycling rate of the cloth bag or filter paper is low, which leads to an increase in the cost of use. Dry dust and garbage, the raised fine powder dust will cause a wide range of air pollution, and cause great harm to the health of operators and surrounding residents.
