Description

Coal gas waste water truck

The utility model relates to the special-purpose vehicle technology, belongs to existing cargo vehicle repacking.The product of this technology is applicable to the waste water in the underground gas water accumulation of pipeline cylinder of coal gas industry suction transportation city.

Existing technology is such:

The segmentation in the underground gas supply line of the city of domestic use coal gas is provided with the ponding cylinder, and is long-pending when a certain amount of when waste water in the ponding cylinder, waste water must be discharged, otherwise influence normal air feed, relates to huge numbers of families' problem concerning life.The habitual behindhand type of manually bleeding that follows of people, because efficient hand-manipulated is not high, discharge of wastewater is on road, and labor strength is big, and efficient is low, causes environment serious dirty seven.

The purpose of this utility model is released special-purpose coal gas waste car, and it is reasonable in design, and the suction convenient transportation is safe and reliable, than manual pumping efficiency height, has prevented environment dirt seven.

The purpose of this utility model can realize by following measure.

Adopt the two class truck chassis transformations of the way (truck chassis that does not promptly have railway carriage), at vehicle frame top (erecting) top for sleeping in one tank body.Safety relief valve 3 is fixed on the flange on tank body top by bolt.Top also is provided with and attracts tapping equipment and floss hole.Force driving device is connected with the speed changer of car transmissions, with the output of car engine mechanomotive force, drives the vacuum pump running of air-channel system.Air-channel system mainly is made up of vacuum pump (single-stage rotary vane type) 11, one way valve 6, cross valve 5 and pipeline.This system extracts air in the tank body 1 out by vacuum pump 11 runnings and makes jar interior negative pressure suction device that forms, and coal gas waste is drawn in the jar in the ponding cylinder.This special-purpose vehicle also is furnished with the extremely alert automatic Presentation Function of safety.

Structure is described:

Fig. 1 is the coal gas waste car after the repacking, every major parameter of former car and performance are constant substantially, connect take-off 8 at former car gearbox power taking window place, drive vacuum pump 11 runnings through the power transmission shaft outputting power, take-off control crank 7 is positioned at driver's cabin, and tank body 1 is positioned at vehicle frame top, it is provided with manual drain device 2, safety relief valve 3, electronic audio alarm water level display unit 4 and suction tube 13, safety relief valve can be used as the inlet of maintenance tank body simultaneously.

Fig. 2: safety relief valve is made up of shell 15, spring 17, sealing ring 18, pressing plate 16, spring 17 acts on pressing plate bottom plate hole is sealed, when the jar internal pressure reaches certain value, the pressure that upper gas produces pressing plate is with length of spring compressed, make on the pressing plate and move, outside the gas drain tank, a restriction jar internal pressure is guaranteed traffic safety.

Fig. 3: suction joint 23 and the matching surface iron chains of taking between 20 are joined sealing ring 22, adopt screw spacing, and joint can rotate freely in adapter place simultaneously, and joint 23 front ends are connected with underground gas water accumulation of pipeline cylinder hose nozzle with screw thread.

Near Fig. 4: when car stops underground gas ponding cylinder, suction joint 12 with suction tube 13 front ends is connected with ponding cylinder effluent pipe mouth earlier, open ball valve 6 simultaneously, pilot engine, depress clutch pedal, promote the take-off control crank 7 in the driver's cabin, make vacuum pump 11 rotations, air in the jar is extracted out, and after ball valve 6, cross valve 5, one way valve 15 entered vacuum pump, the oil-containing gases of discharge flowed back to cross valve through gs-oil separator 9 again and enters atmosphere.When vacuum value was to certain limit in vacuum meter 14 demonstrates jar, the waste water in the ponding cylinder was inhaled in the jar by suction tube.In the gs-oil separator 9 lubrication oil is housed, lubrication oil enters vacuum pump 11 through oil rectifier 10 and discharges with gas when the vacuum pump work, the oil that oil-containing gases is separated in gs-oil separator sinks in the housing and is recycled, its effect is lubricated vacuum pump, sealing, cooling guarantees that vacuum pump works well.

Full (warning) level displaying device of Fig. 5 electronic audio newspaper.

When liquid level in the tank body reaches the rated capacity height, full (alarm) 27 of electronic audio newspaper sends signal, level displaying device sends sound equipment automatically and signal shows, remind the operator in time to take measures, close ball valve 6, stop vacuum pump work simultaneously, prevent to flow to air-channel system and cause the fault effects normal operation because of tank body overflows, reference test bar 25 is positioned at tank body among the figure, 2 test points are arranged on it, distance between 2 is equivalent to the liquid height of tank body rated capacity 1/5th, when on liquid level is continuous, opening, each test point is delivered to the small-signal that records the display 26 in the driver's cabin respectively, put luminous point on the bright display step by step through amplifying signal, demonstrating liquid level capacity in the tank body, when liquid level during to the highest test point, signal is sent to the alarm 27 that is combined into one with display 26 simultaneously, and this signal promotes alarm equipment alarm after amplifying.

The function of this special-purpose vehicle is: suction: discharging is described in detail by following embodiment 2: Fig. 1 also are that the utility model is implemented accompanying drawing, and repeatedly water sorption is meant that vacuum of tank body can repeatedly aspirate the interior waste water of two above ponding cylinders.After being the waste water in ponding cylinder of vacuum draw of tank body, (the ordinary circumstance lower tank can not be filled to rated capacity) closes two ball valves 6 immediately simultaneously as residue in the jar enough vacuum values.Only need during next time suction operation the ball valve of suction tube leading section is opened, the waste water sucking-off can be worked as, a vacuum values drops in limited time and by the suction job requirements vacuum pump is turned round again again in jar.

Discharging:

When the waste water that is filled jar is transported to suitable place, handles tapping equipment 2 waste water is flowed out through floss hole.

Advantage of the present utility model:

1, handsome in appearance, reasonable in design, multiple functional.

2, simple to operate, the maintenance aspect, with low cost.

3, prevented environmental pollution, had than the great society benefit, received praises from customers.
