An environmentally friendly and efficient sanitation vehicle

Abstract

An environmentally-friendly and efficient sanitation vehicle comprises a vehicle chassis, a garbage bin, a fan, a suction nozzle, a suction pipe, a liquid cleaning and filtering dust removing device,wherein an inlet of the device is communicated with the garbage bin, an outlet of the device is communicated with the fan, and dust removing liquid is arranged in the chassis; the fan works to producenegative pressure, make garbage enter that suction pipe through the suction nozzle, and then enter the garbage bin, most garbage is deposited in the garbage bin, a small amount of dust enters and dissolves in the dust-removing liquid with the airflow, and the clean gas out of the dust-removing liquid is discharged through the fan. The invention can realize cleaner and environmentally friendly airdischarged from the blower of the sanitation vehicle and avoid secondary dust. Saving water; Significant reduction in vehicle energy consumption and exhaust emissions; Strong suction, long mileage, significantly improve the efficiency of the vehicle; Reduce the cost of manufacturing and using the vehicle, save time and labor for operators; Ensure that sanitation vehicles operate normally in winter; Reduce random dumping of sewage.

Description

technical field [0001] The invention relates to a special-purpose vehicle, including the field of municipal sanitation vehicles, and in particular to a sanitation vehicle with a liquid cleaning, filtering and dust-removing device, including road sweepers, sweepers, dust collectors, dry sweepers and the like. Background technique [0002] Road sweeper is a general term for a class of sanitation vehicles, including vehicle chassis, dustbins, centrifugal fans, suction cups (suction nozzles), suction pipes and accessories, of which the dustbin contains inlets, outlets and tailgates. Its basic working principle is that the suction nozzle is connected to the inlet of the suction pipe, the suction pipe is connected to the inlet of the dustbin, and the outlet of the dustbin is connected to the inlet of the centrifugal fan; the vehicle chassis carries these parts and drives at low speed on the road; Negative pressure is generated at the mouth, and the air and garbage on the road are ...

AI Technical Summary

Problems solved by technology

This directly shortens the continuous and sustainable working time of the road sweeper, so in actual use, the road sweeper often needs to stop sweeping due to lack of water and go to the water source to add water, losing a lot of time and fuel consumption

[0019] 2) The work efficiency of the road sweeper is significantly reduced

The whole drainage process usually takes 10 minutes to 30 minutes, and the road sweeper usually drains water 2 to 6 times a day. Among them, the washing and sweeping car with a large water consumption usually needs to be drained every half an hour, which greatly reduces the cleaning time of the road sweeper. work efficiency

[0020] 3) The work efficiency of the road sweeper is significantly reduced

A very large garbage bin can actually only load very little garbage due to the above reasons, which leads to a reduction in the single continuous working capacity of the road sweeper

[0021] 4) The work efficiency of the road sweeper is significantly reduced

[0022] 5) Road sweepers consume a lot of water and waste water resources

At Nozzle 2 and Nozzle 3, the fine water mist used for spraying dust reduction and the passing garbage need to be fully contacted to achieve a good dust reduction effect, but the high-speed airflow here has a negative impact on the full contact between the two, and this should be improved problem, it is necessary to increase the water supply and water supply pressure, which in turn brings about the problems of large water consumption, more frequent sewage discharge and high fuel consumption

Therefore, the design of this road sweeper can only balance the advantages and disadvantages as much as possible, but cannot completely solve the problem.

[0023] 6) Large water consumption, waste of water resources

However, these devices take up a large amount of the internal volume of the dustbin, and significantly increase the cost of vehicle manufacturing and post-use maintenance costs

[0024] 7) The road sweeper consumes a lot of fuel

Therefore, the road sweeper with water spray dust reduction cannot be used in the northern winter

Existing vehicles used for road cleaning in winter in the north are all dry-type road sweepers without clean water tanks and cannot be sprayed to reduce dust. After the garbage is sucked into the dustbin, a large amount of dust will be ejected again with the fan, forming secondary secondary environmental pollution, this problem has not been well resolved

Since the dumped garbage is accompanied by a large amount of sewage, this will bring additional workload and cost to subsequent sewage collection and treatment, garbage compression, and centralized garbage transportation.
