Combined suction sewage truck ultrasonic wave mud-water separation total system
Technical field
The present invention relates to the tripping device of combined suction sewage truck, refer to particularly a kind of combined suction sewage truck ultrasonic wave mud-water separation total system.
Background technology
In the waste disposal plant of current suction-type sewer scavenger, by the arrangement form of processing unit, substantially can be divided into following two classes:
1, sewage separation equipment and vacuum tank integrated arrangement.In tank, be provided with and drive power-actuated separation barrel, utilizing vacuum pump to vacuumize is drawn into sewage in separation barrel, cylinder rotates under power wheel drive, high-pressure hydraulic pump injects high pressure clear water in cylinder and rinses mud simultaneously, sewage flows into sealed shell of tank or directly via pipeline, discharges from cylinder surrounding, and mud is trapped in cylinder or tank interior.
2, sewage separation equipment and vacuum tank apart arrangement.This scheme adopts the anti-row of pressure or adopts the mode of impeller pump pump drainage that the mud being drawn in vacuum tank is delivered to individual curing in mud and water separating equipment, mud and used water are sent in classification, and the main technical principle of its use comprises centrifugation, the stirring of slag slurry, mechanical vibration etc.But this technology exists more problem at present, not mature enough, apply not general.

Effluent cycle re-use device in combined suction sewage truck ultrasonic wave mud-water separation total system of the present invention comprises filter cylinder swing arm 9, lifting hydraulic ram 10, elementary centrifugal dirty water pump 8, one-level swirler 26, the cascade filtration foul water tank 24 connecting successively, secondary centrifugal dirty water pump 23, second cyclone 21 and filtered water tank 20.
Filter cylinder swing arm 9 is articulated with on tank body 11, and filter cylinder swing arm 9 is provided with locating shaft, and this locating shaft is inserted in the centre hole of rotating filter cartridge 7, and rotating filter cartridge 7 rotates around locating shaft.Rotating filter cartridge 7 drives by rotary hydraulic motor 12, lift cylinder 10 is hinged with vacuum tank 11, piston rod front end in lift cylinder 10 is connected with filter cylinder swing arm 9, and piston rod drives filter cylinder swing arm 9 motions under the driving of hydraulic pressure, thereby filter cylinder swing arm 9 driven rotary filter cylinders 7 rotate.
Elementary centrifugal dirty water pump 8 connects rotating filter cartridge 7 water outlets, the other end connection one-level swirler 26 water-ins by pipeline one end.The water outlet of one-level swirler 26 is connected to cascade filtration foul water tank 24 by pipeline, secondary centrifugal dirty water pump 23 respectively with cascade filtration foul water tank 24 and second cyclone 21 water-ins, second cyclone 21 water outlets are connected to filtered water tank 20, second cyclone 21 slag notches directly lead to tank interior, and 22 of high-pressure hydraulic pumps are from filtered water tank 20 water intaking back-flushing rotary filter cylinders 7 or dredge for high pressure.Effluent cycle re-use device can be according to the inner sewage level height of vacuum tank 11, by lift cylinder 10, regulate the position of rotating filter cartridge 7, rotary hydraulic motor 12 drives rotating filter cartridge 7, stirring-up sewage, sewage enters by the filter pore on rotating filter cartridge 7 surfaces the rising pipe that rotating filter cartridge connects, sewage after initial filter is sent into one-level swirler 26 cyclonic separation via elementary sump pump 8, then enter cascade filtration foul water tank 24, via secondary sump pump 23, be drawn into second cyclone 21 cyclonic separation again, qualified water after separation is recycled to filtered water tank 20, can start if desired high-pressure hydraulic pump 22 and take out high pressure water back-flushing rotary filter cylinder 7 from filtered water tank 20, the filter pore that prevents rotating filter cartridge 7 surfaces is blocked, and the silt of accumulation can be discharged by manual ball valve 25 in cascade filtration foul water tank 24.
The anti-arranging device of sewage in combined suction sewage truck ultrasonic wave mud-water separation total system of the present invention comprises: vacuum pump, floating drum 14, float guide 16, anti-flexible pipe 15, knife gate valve I, knife gate valve II and other pipelines arranged.Vacuum pump is communicated with vacuum tank 11 by airway, and floating drum 14 is positioned at vacuum tank 11 inside and floats on sewage level surface, and the traction by float guide 16 can swing along perpendicular.
Anti-row's flexible pipe 15 is connected on floating drum 14 and is opening down.In vacuum tank 11, be provided with thrust-augmenting nozzle 27, one end of thrust-augmenting nozzle 27 is communicated with the upper end of anti-row's flexible pipe 15, and the middle part of thrust-augmenting nozzle 27 is communicated with a rising pipe 28, and the mouth of pipe of rising pipe 28 extends to the outside of vacuum tank 11; Knife gate valve I is located between one end and rising pipe 28 of thrust-augmenting nozzle 27, and knife gate valve II is located between described rising pipe 28 and the other end of thrust-augmenting nozzle 27.
According to actual condition, when needs are anti-while arranging decrement operation, while starting in the reverse tank of vacuum pump pressurization, opening knife gate valve I, close knife gate valve II, in tank, upper water is discharged vacuum tanks from anti-row's flexible pipe 15.When needs aspirate sewage operation, start vacuum pump and vacuumize from vacuum tank, opening knife gate valve II, close knife gate valve I, sewage under atmospheric pressure enters vacuum tank.
As shown in Fig. 3, Fig. 4, Fig. 5, the anti-arranging device of mud in combined suction sewage truck ultrasonic wave mud-water separation total system of the present invention comprises: two cover tank internal screw thrusters 18, a set of tank external spiral thruster 28, advancing hydraulic pressure motor 17, tank body elevating ram 27.The bottom that two cover tank internal screw thrusters 18 are arranged symmetrically in tank body, every cover tank internal screw thruster 18 is all driven by two advancing hydraulic pressure motors 17, and tank external spiral thruster 28 is arranged in the mid-way of tank body outer bottom, by a set of advancing hydraulic pressure motor, is driven.Through ultrasonic pretreatment, anti-row after decrement, in tank, remaining residue is mainly mud and other foreign material of moisture content less, start immediately the anti-arranging device of mud: first start tank body elevating ram 27 tank body afterbody is lifted to the certain angle that leans forward, mud surface water flows to anterior accumulation, control lift cylinder 10 and adjust rotating filter cartridge 7 positions, can further filter residue surface water.After draining completes, two cover tank internal screw thruster 18 rotating Vortexes, mud is pushed to tank body afterbody along two hump grooves of tank base (shown in Fig. 5).Tank body afterbody has an openable valve, tank external spiral thruster 28 under the driving of advancing hydraulic pressure motor with valve automatic butt, then circular knife inserts certain depth (as shown in Figure 4) in tank, just can combine tank internal screw cutter by the mode of relay and jointly complete the task that mud is released.Thereby realize the anti-process of arranging of whole mud.
The above whole operation process, vacuum soil pick-up with ultrasonic wave sewage separated pre-treatment should preferentially implement, then can be according to the difference of site work amount, sludge moisture content, mud impurity component, be used in conjunction with anti-decrement and the effluent cycle recycling function of arranging of pressure, not only collaborative but also independent, make flexible arrangement in good time.
