Problems solved by technology

In fact, the flow air volume generated by the fan of the sweeping suction road sweeper is about 3000m 3 /h~10000m 3 /h, when the ambient temperature is -10°C or -20°C, it is difficult to prevent the atomized water droplets ejected from the nozzle from freezing in the fast-flowing cold air only

[0046] Figure 7 It is a structural schematic diagram of the second embodiment of the road sweeper of the present invention. Such as Figure 7 As shown, the road sweeper in this embodiment is an extension of the aforementioned first embodiment, and its main structure includes a vehicle frame 1, a dustbin 2, a butterfly sweep brush 5, a water tank 21, a water pump 22, a nozzle 4, and a fan 6 , on the basis of the semi-enclosed dust collection tent 12 and the support frame 13, the suction passage 8 is canceled, and in the semi-enclosed dust collection tent 12, a pair of butterfly sweeping brushes 5 on both sides of the vehicle frame 1 are installed in sequence. Only the suction cup 3, the connecting rod mechanism or cable mechanism driven by the hydraulic cylinder will put down the butterfly brush 5 and the suction cup 3 on the same side at the same time during work, and lift them up at the same time when they are in transition. Both suction cups 3 are equipped with suction cyl...

Abstract

The invention relates to a road sweeper as well as a cleaning operational method. The road sweeper comprises a water tank, a garbage box and a filter screen arranged on a vehicle frame, a water pump made of copper, aluminum or stainless steel material and communicated with the water tank is also disposed on the vehicle frame, a butterfly shape brush and a suction cup are arranged at both sides of the vehicle frame respectively, a suction roll communicated with the garbage box is arranged on the suction cup, a fan communicated with the garbage box is mounted on the vehicle frame, a semi-closed dust-collecting curtain is arranged under the vehicle frame for covering the butterfly shape brush, and the suction cup is communicated with the semi-closed dust-collecting curtain, the fan sucks dust and garbage swept by the butterfly shape brush by dry method in the semi-closed dust-collecting curtain to form a dusty airflow to enter the garbage box through the suction cup and the suction roll, and the water pump pumps snow-melting agent aqueous solution in the water tank and sprinkles the solution to the dusty airflow through a nozzle arranged in the suction cup and/or the suction roll, the fan pumps the clean airflow undergoing gravity settling and filtration by the filter screen in the garbage box and discharges the airflow through an exhaustion channel, and the road sweeper can be used for sweeping operations by dry method or wet method, and has advantages of good wet-type dust control effect and environmental protection of operations.

Description

technical field [0001] The invention relates to sanitation equipment and its working method, in particular to a road sweeper and its cleaning operation method. Background technique [0002] Due to seasonal changes and geographical reasons, when sweeping suction road sweepers are used for cleaning operations in northern cities in winter, the water in the water tank is easy to freeze, and the garbage in the garbage bin is easy to freeze, and when the water is sprayed on the ground, it will form thin ice. It is easy to cause pedestrians to fall or vehicles to skid, causing unsafe hidden dangers in urban traffic. [0003] In order to solve the above problems, the prior art has proposed multiple technical solutions for wet and dry road sweepers. Although the structure of a variety of wet and dry road sweepers can be divided into single-stage dust filter or multi-stage dust filter, their working principle is basically the same, that is, in the process of dry cleaning operation, i...
