Disc system, low pressure water mist system (with low-pressure pump), heavy pressure fine spray system (with high-pressure hydraulic pump), vacuum is swept to inhale Dust hood etc. is all the auxiliary equipment of sweeping machine.Wherein, the rubbish that disc system can be sticked to road surface with assisted collection rubbish and loosening is swept； Dust that low pressure water mist system can inhibit sweeping disc for road sweeper to raise during the work time and avoid dust and rubbish by from Heart blower is discharged into external environment again；Vacuum cleaning cover is for absorbing the dust sweeping disk and raising at work；High pressure fine water Mist flushing system can reinforce road surface cleaning capacity and atomizing de-dusting ability.According to different applications, sweeping machine is not with Same auxiliary device, has just evolved into different modification vehicles, these subdivision vehicles are usually referred to as and sweep road by industry personage Vehicle, sweeper, vacuum sweeper, dry-type road sweeper, wet type sweeping machine etc., or according to whether vehicle is divided into suction sweeping type with disk is swept Sweeping machine or only absorbing sweeper truck.In addition, a large amount of ground sewage can be drawn into rubbish in operation by sweeping machine, sweeper etc. Case, so dustbin is also often referred to as foul water tank by insider, it is herein, unified that dustbin or foul water tank are referred to as rubbish Rubbish case.

In order to make it easy to understand, the notable feature of above-mentioned several subdivision vehicles is described first below.And in fact, These subdivision vehicles not stringent differentiation and unified standard, different producers can be according to practical customer demand freely by these Product feature is combined.

1) sweeping machine: there is no high-pressure hydraulic pump；With low-pressure pump (usually automatically controlled diaphragm pump), cooperate spray head sweep disk, Place injection low pressure water mist, is used for atomizing de-dusting inside suction nozzle, dustbin etc.；There are four sweep medium-and-large-sized sweeping machine usually band Disk sweeps the front that disk is arranged in vehicle rear wheel, and there are two on each side；There is usually one suction pipes and a suction nozzle for drawing rubbish, Suction pipe and suction nozzle are arranged in rear-wheel rear middle position.

2) sweeper: having high-pressure hydraulic pump (usually plunger pump), cooperates spray head, realizes high-pressure high-flow water mists, can To be used for Street surface cleaning, it can also be used to atomizing de-dusting；With low-pressure pump (usually automatically controlled diaphragm pump), spray head is cooperated to sweep The place injection such as disk, suction nozzle, dustbin inside low pressure water mist, is used for atomizing de-dusting；Usually band is swept disk and is arranged in there are two disk is swept The front of vehicle rear wheel, every side one；Usually there are two suction pipes and a shared suction nozzle for drawing rubbish, and suction pipe is arranged in In front of rear-wheel, every side one, suction nozzle is arranged in the middle position in front of rear-wheel.

3) vacuum sweeper: usually not high-pressure hydraulic pump；Do not sweep disk；Usually there are two or four suction pipes and disjunctor, Shared suction nozzle is for drawing rubbish；With or without low-pressure pump, spray head can be cooperated to exist with low-pressure pump The local atomizing de-dusting such as inside suction nozzle, dustbin.

4) dry-type road sweeper: there is no high-pressure hydraulic pump；There are two bands or four are swept disk；There are two bands or four suction pipes； There is no spray head sweeping Pan Chu, can not achieve atomizing de-dusting；It is covered with vacuum cleaning cover and sweeps disk, and cooperate suction pipe that will sweep what disk raised Dust is drawn into dustbin together.

Sweeping machine described in this patent be refer to a kind of environmental sanitation municipal administration vehicle, including it is all using blower carry out dust suction and The vehicle of road-cleaning, particularly including vacuum sweeper, dry-type road sweeper, wet type sweeping machine, sweeper, sweeping machine etc..This patent institute The innovative technology of description is a common technology, be suitable for above-mentioned all vehicles, for ease of description, behind by these segment vehicle Type is referred to as sweeping machine, no longer described separately.

When sweeping machine carries out sweeping road operation, centrifugal blower high speed rotation generates negative pressure by centrifugal action, and air is by suction nozzle Sucking, and successively pass through suction pipe, dustbin, blower, finally it is discharged to the outside in environment.Rubbish near suction nozzle is due to negative pressure With by the air draught drive of high-speed motion, can be inhaled into suction nozzle together with air, and reached in dustbin by suction pipe. Since rubbish box space is very big, air velocity can reduce suddenly, and rubbish can be comprehensive due to Gravity Separation and air rotating separation Cooperation is with decomposing；Gross mass big (such as brick) and density ratio biggish (such as clod, stone, iron nail, glass Fragment) rubbish can first be deposited in dustbin bottom, and air and the rubbish not settled continue to move to dustbin export direction.Due to Dustbin is bigger, and air velocity is relatively low, and air residence time in dustbin is longer, reaches dustbin in air and exports it Before, most rubbish can settle, but still suffering from a small amount of dust and rubbish can be exported simultaneously along with air by dustbin It enters blower and is discharged into external environment to generate secondary air pollution eventually by fan outlet.In order to as far as possible Reduce secondary air pollution, that is, the air for allowing blower to be discharged is as clean as possible, usually on sweeping machine using following part or Whole depositing dust schemes:

1: Pan Chu installation water mist spraying head 1 is being swept, usually by multiple sprinkler compositions.The water mist that water mist spraying head 1 sprays is by ground Drench, so that these rubbish such as floating dust, tiny dust and water are sufficiently mixed, due to the bond effect of water, these tiny rubbish Rubbish can be coagulated together the rubbish for becoming more bulk or tiny rubbish and can be bonded on bulk rubbish.It sweeps disk and collects these Just do not allow to be also easy to produce dusty phenomenon when rubbish.There are also agitations, impact to ground refuse for the water flow that water mist spraying head 1 ejects It is acted on high-pressure wash, allows rubbish to be easier to be swept disk collection, also allow ground cleaner.

2: water mist spraying head being installed at the rear ground gap of the binding site or close suction nozzle of rubbish suction nozzle and suction pipe 2, usually by multiple sprinkler compositions.The rubbish of water mist and sucking that water mist spraying head 2 sprays is mixed, and is further bonded rubbish Together, consolidate adhesive effect in other words, so that rubbish is easier to settle after entering dustbin.The water that water mist spraying head 2 ejects There are also agitations and percussion to ground refuse for stream, and rubbish is allowed to be easier to be sucked by suction nozzle.

3: appropriate location (usually exports the place of rear a distance, herein air-flow apart from suction pipe inside dustbin Flow velocity is still very high) installation water mist spraying head 3, usually by multiple sprinkler compositions.Water mist spraying head 3 sprays the rubbish hair of water mist and process Raw mixing promotes rubbish sedimentation again.

4: before dustbin outlet, large area filter screen or/and air filtration cartridge (filter core) being installed, air is allowed to enter blower The dust and rubbish passed through before by the filtering of filter screen or/and air filtration cartridge, the overwhelming majority can be filtered and be retained in Inside dustbin.Usual sweeping machine and sweeper are due to there is atomizing de-dusting measure, so only with plane or the band of cube There is the metal screen (metal plate) of small-bore hole to can reach preferable filter effect；And vacuum sweeper leads to because not sweeping disk It is often insufficient without atomizing de-dusting measure or atomizing de-dusting capacity of equipment, and the environment to work more severe (such as steel mill, mine Mountain, Dust Capacity are very big), so usually first level-one coarse filtration is carried out using metal screen, then again with the cylinder of multiple large sizes Shape air filtration cartridge carries out the filtering of second level essence.

The product that low-pressure pump (such as automatically controlled diaphragm pump) is either still used using high-pressure high-flow high-pressure hydraulic pump, is adopted It may be referred to collectively as atomizing de-dusting apparatus with the device of water mist spraying head.

After generalling use above scheme, the air for reaching fan air inlet is cleaner, the sky of blower discharge Gas can satisfy environmental sanitation requirement.

By being analyzed above it is found that using above-mentioned atomizing de-dusting apparatus and filter device, blower discharge can be significantly improved The cleanliness of air, but have distinct disadvantage below:

1) sweeping machine working efficiency significantly reduces, and oil consumption increases.Reason one needs often to add water.Sweeping machine is due to space With the limitation of gross combination weight, it is impossible to configure very big water tank, so sweeping machine is at work, not usually dustbin is full It needs soot to tip rubbish, but needs to add water that could continue operation again because of water tank sky.This directly shortens and sweeps road The continuous sustainable working time of vehicle, so sweeping machine is often because water shortage needs to stop to sweep road and go to water source in actual use Place plus water, have lost plenty of time and oil consumption.

2) sweeping machine working efficiency significantly reduces.Reason two needs often to drain.In order to which atomizing de-dusting just needs largely to spray Water, a large amount of water enter in dustbin along with rubbish, and whole rubbish (including water) in dustbin will quickly increase and increase Height, sweeping machine can also stir the water in dustbin in the transportational process to loiter, generate wave.If water arranged not in time Out outside vehicle, part dirty water and rubbish are possible to reversely drop to from suction pipe and generate pollution on road surface, or are sucked simultaneously by blower again It is discharged to the outside in environment again, this process can also the equipments such as Rapid Damage blower.In order to ensure fan safe and keep away Exempt from sewage to trickle down to road surface, sweeping machine just must often stop operation, and vehicle is parked in roadside, and by dustbin tail-gate Sewage in dustbin is periodically discharged outside vehicle sewage discharge ball valve.Entire drainage procedure usually at 10 minutes to 30 minutes, and As soon as sweeping machine day drains usually at 2 to 6 times, wherein the big sweeper of water consumption usually per half an hour needs to drain once, this Greatly reduce the working efficiency of sweeping machine.

3) sweeping machine working efficiency significantly reduces.Reason three, dustbin volume could not be fully utilized.For atomizing de-dusting Water and rubbish be all absorbed and be stored in a shared dustbin, equivalent to increase total garbage bulk, especially For sweeper, when sweeping road, the major part of dustbin sucking is water, and fraction is true rubbish, this leads to dustbin Volume cannot be fully utilized.Also, since the ratio of the water in the rubbish aqueous solution is very high, the high solid refuse of density is logical It is often deposited in lower part, and the rubbish of a large amount of dirty water and low-density floats on top, free-flowing is in, since vehicle is being transported It receives traffic influence during defeated rubbish to be frequently necessary to brake and accelerate, this will lead to dirty water and flows everywhere in dustbin And raise the waves, in order to ensure during transportation, the rubbish and dirty water of low-density will not be started by wave and be fallen along suction pipe It flows back on road surface, it is 20 to 60 centimetres low that the design of sweeping machine is fully loaded with height of rubbish (dirty water) height usually than suction pipe outlet.This It is meant that the dischargeable capacity of dustbin: whole volumes usually only 1:4 of dustbin is even lower.One very big rubbish Case can only actually load considerably less rubbish for these reasons, and which results in the reductions of sweeping machine single continuous work ability.

4) sweeping machine working efficiency significantly reduces.Reason four, water are used in unwanted place.Sweeping machine at work, Atomizing de-dusting is all carried out to all rubbish being absorbed into, and this is not necessarily to.Such as brick, coin, screw etc. these Big quality or highdensity rubbish, after they reach dustbin inside, even if the not adhewsive action of water, can also settle quickly Without being discharged to the outside environment again by blower in dustbin.And existing sweeping machine is at work to these rubbish Meeting atomizing de-dusting, will consume water more naturally.If sweeping machine at work being capable of more targeted atomizing de-dusting, that is, true Protect blower discharge air purity under the premise of, only to necessary rubbish carry out atomizing de-dusting, and to other rubbish not into Row atomizing de-dusting will reduce water consumption naturally, then the sweeping machine with same capacity filtered water tank can continue working more The long time, to improve working efficiency.

5) sweeping machine water consumption is big, waste water resource.Reason one, water consumption is big.In order to ensure dust-laying effect, it is necessary to spray Many water can be only achieved purpose, so the daily need of work of sweeping machine wastes a large amount of urban water.This is lacked in global water resources The weary epoch do not meet the theory of environmental protection.At nozzle 2 and nozzle 3, needed for the water mists of atomizing de-dusting and the rubbish of process The dust-laying effect that can have just played is come into full contact with, but the high-speed flow at this comes into full contact with the two and plays negative effect, Improve this problem, must just increase water supply and pressure of supply water, this brings again, and water consumption is big, needs more frequent sewerage The big problem with oil consumption.So the design of this sweeping machine can only balance as far as possible each pros and cons wherein and cannot thoroughly solve Problem.

6) water consumption is big, waste water resource.Reason two, water cannot reuse.It dumps rubbish every time, the rubbish in dustbin Rubbish and water all can be outwelled all.These water cannot be used again in sweeping road depositing dust, waste water resource.To solve this problem, There is part sweeping machine producer to attempt that sewage recovery reutilization device is installed in sweeping machine to reduce the overall usage amount of water.But Be that these devices occupy a large amount of dustbin internal volumes, and significantly improve vehicle manufacture cost and later period working service at This.

7) sweeping machine oil consumption is big.Reason one, vehicle gross mass are big.When being continued working in order to ensure atomizing de-dusting effect and vehicle Between, sweeping machine needs to be equipped with very big water tank and the topped up with water before start-up operation, this causes gross combination weight big.Heavy vehicle exists Vehicle parking place-sweeping road place-is shuttled between place of tipping rubbish, and is necessarily required to a large amount of fuel consumption.

8) sweeping machine (sweeper) oil consumption is big.Reason two, high-pressure hydraulic pump power are big.For sweeper, by high pressure The high-pressure hydraulic pump of big flow, above-mentioned spray head can be realized better atomizing de-dusting effect.But the driving power of high-pressure hydraulic pump is very Greatly, usually 25 to 40kw or so, this requires to provide power by vehicle itself, can dramatically increase the oil consumption of sweeper naturally.

9) sweeping machine oil consumption is big, and working efficiency is low.Reason three, air filtration cartridge increase blower both ends draught head.Vacuum sweeper It is mainly used for absorbing tiny dust, for example is used for mining site or steel mill.Since dust content is very big in the rubbish of this occasion, it is Ensure that the air of blower discharge is clean enough, just must the connection fans entrance inside dustbin front end installation it is multiple big The air filtration cartridge of volume, the air that convection current enters blower are filtered.But because dust is excessive in rubbish, filter core can block up quickly Plug, the filter core of blocking can dramatically increase the draught head at blower both ends, and fans load becomes larger, to consume more fuel oils.In addition, In order to guarantee that vacuum sweeper works normally, vacuum sweeper needs often clean or replace these large-scale air filter cylinders, to reduce Working efficiency increases the manufacturing cost and use cost of vehicle.

10) secondary environmental pollution is brought.Usually there is a sewage valve on dustbin tail-gate, having expired when dustbin sewage needs When draining, some sweeping machine drivers are directly arbitrarily discharged into road side by sewage valve goalkeeper sewage to save trouble, and produce Raw secondary environmental pollution.

11) idleness of equipment of sweeping machine in winter is wasted than more serious.The reason is that can not be in 0 degree of northern weather below Normal operation.Water in sweeping machine water tank is all used for atomizing de-dusting or high-pressure wash, and the water that a part ejects directly stays in Road surface, a part of water are inhaled into dustbin and then are also poured onto roadside or refuse depot, i.e., the water in all water tanks It is all disposably consumed and cannot be utilized again.If the not atomizing de-dusting effect of water, traditional sweeping machine work It will lead to dust to fly upward everywhere, the largely dry dust sucked in dustbin can be sucked by blower and be discharged into the external world again To generate secondary pollution in environment.Due to the limitation of cost and environment protection emission, the water in water tank is taken from tap water, industrial Water or fire hydrant supply water, it is impossible to add the liquid medium for reducing freezing point of similar anti-icing fluid thereto to ensure to sweep road Vehicle carries out atomizing de-dusting when sweeping road 0 degree of winter below.So the sweeping machine with water spray depositing dust is can not be in the north Use in winter.The existing vehicle that road surface cleaning effect is carried out in north of china in winter is all dry-type road sweeper, without filtered water tank, cannot be sprayed Mist depositing dust, after rubbish is inhaled into dustbin, a large amount of dust can be sprayed again with blower, form secondary environmental pollution, This problem is never by very good solution.

12) extra workload, difficulty and cost are brought to rubbish post-processing.Due to the rubbish companion poured Have large amount of sewage, this to subsequent sewage collecting and processing, garbage-compressing, rubbish collective conveyance etc. bring extra workload and Cost.
