Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments；
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model fecal suction truck pressure guiding deodorization device, including vacuum system, deodoration system and
Control system；
The vacuum system includes vacuum pump 23, flow switch 12, moisture trap 16, pressure sensor 13 and tank body
20；It include two states of suction and anti-row when vacuum system works, when suction, vacuum pump 23 siphons away sky out of tank body 20 first
Gas is made tank body 20 is inside and outside to form Negative Pressure Difference, and then passes through extraneous liquid manure using atmospheric pressure and inhale in excrement mouth indentation tank body 20, and
Tail gas then passes through mixing chamber 2 and is discharged；As anti-row, the flow direction of entire gas circuit is on the contrary, i.e. vacuum pump 23 is sucked from mixing chamber 2 first
Then air pumps air into tank body 20 again, so that the pressure in tank body 20 is greater than extraneous atmospheric pressure, and then liquid manure is pressurizeed
Quickly discharge.Suction and anti-two states of row pass through flow switch 12 and realize mutual switching；
The deodoration system includes that deodorant liquid holding vessel 6(storage inside has deodorant liquid 5), deodorant liquid delivery pump 8, flow tune
Save device 4, atomizer 3 and mixing chamber 2；When vacuum pump 23 is started to work, deodorant liquid delivery pump 8 is worked at the same time, and deodorant liquid is stored up
The deodorant liquid in tank 6 is deposited to be sucked out and be pumped into mixing chamber 2, with vacuum pump 23 be discharged tail gas hybrid concurrency life react, and into
Before entering mixing chamber 2, deodorant liquid has also passed through flow regulator 4 and atomizer 3 respectively, and flow regulator 4, which can receive, comes from CPU
The signal of controller 11, and according to the aperture of Signal Regulation pipeline, deodorant liquid can be atomized by atomizer 3, so as to make deodorant liquid with
The tail gas that vacuum pump 23 is discharged substantially more reacts.
The control system includes power supply 10 and cpu controller 11, and cpu controller 11 and flow regulator 4, deodorant liquid are defeated
Pump 8, pressure sensor 13 and flow switch 12 is sent to be electrically connected, power supply 10 is to cpu controller 11, deodorant liquid delivery pump 8, flow
Adjuster 4 and pressure sensor 13 are powered；Wherein cpu controller 11 can be interior default with the panel of setting inner parameter
Logical relation between flow switch 12, pressure sensor 13 and flow regulator 4, can respectively from flow switch 12 with
And pressure sensor 13 receives signal, and handles by integration procedure, issues regulating command to flow regulator 4, then reaches
The purpose of deodorant liquid the amount of injection is guided by vacuum system pressure size.In addition, being prefixed vacuum system pressure in cpu controller 11
The associated data of gas flow and the associated data of flow regulator 4 aperture and deodorization flow quantity in power and vacuum tube, and can
It is adjusted according to gas flow in the pressure and vacuum tube of vacuum pump 23 and deodorant liquid delivery pump 8, while being also prefixed immediately
Proportion relation between tail gas of vacuum gas pump flow and deodorant liquid, and any adjustment can be carried out according to actual needs；
The tank body 20, which has, inhales excrement mouth 21 and defecation mouth 22, and the top of tank body 20 is connected with anti-overflow device 18, anti-overflow device 18,
Moisture trap 16, flow switch 12 and mixing chamber 2 are sequentially connected by vacuum tube 17, vacuum pump 23 and flow switch 12
Also it is connected using vacuum tube 17；Pressure sensor 13 is connected on vacuum tube 17 by surveying pressure hose 18, for detecting vacuum system
The pressure state of system；
2 bottom of mixing chamber has tracheae 1, and atomizer 3 is connected to the deodorant liquid entrance at 2 top of mixing chamber, deodorization
Liquid delivery pump 8 and flow regulator 4 are connected in turn between deodorant liquid holding vessel 6 and mixing chamber 2 by deodorant liquid delivery pipe 7.
Pressure vacuum gauge 14 is connected on the pressure sensor 13, the pressure value that pressure sensor 13 acquires is shown in very
On hollow pressure gauge 14.
The vacuum pump 23 is sequentially connected by transmission shaft and fecal suction truck chassis power taking mouth.
Working principle of the utility model is: guiding deodorant liquid the amount of injection according to vacuum system pressure size, then reach
Save the purpose of deodorant liquid cost.When fecal suction truck is in running order, power supply 10 is defeated to cpu controller 11, deodorant liquid simultaneously
It send pump 8, flow regulator 4 and pressure sensor 13 to power, keeps each component in running order, at this point, cpu controller 11
Signal is read from flow switch 12 first, judge airflow direction and determines which kind of working condition fecal suction truck is at this time according to this
(suction or anti-row), if fecal suction truck is in aspiration phases, cpu controller 11 can read pressure value from pressure sensor 13,
The associated data and flow regulator 4 that vacuum system pressure and gas flow in vacuum tube are preset in cpu controller 11 are opened
The associated data of degree and deodorization flow quantity, therefore cpu controller 11 can be by judging the gas in vacuum tube according to pressure value
Flow, and the uninterrupted (gas in the flow and vacuum tube of tail gas of vacuum gas pump of tail gas of vacuum gas pump in mixing chamber 2 is obtained simultaneously
Flow is identical), cpu controller 11 is matched according to tail gas of vacuum gas pump flow and deodorant liquid with the preset of tail gas of vacuum gas pump flow at this time
Than sending adjustment signal to flow regulator 4, flow regulator 4 is according to the uninterrupted of Signal Regulation deodorant liquid.Finally, through
It crosses the deodorant liquid being atomized and tail gas of vacuum gas pump and is sufficiently mixed reaction in mixing chamber 2, to achieve the purpose that deodorization.Wherein, air
Anti-overflow device 18 and moisture trap 16 can successively be passed through, anti-overflow device 18 can prevent liquid manure to be inhaled into vacuum pump 23 and cause vacuum pump
23 damages, moisture trap 16 can filter out moisture in air, to play the role of protecting vacuum pump 23.
And if it is to be in anti-row pattern state that cpu controller 11, which judges vacuum system, it can immediate instruction flow regulator 4
Deodorization flow quantity is adjusted to and shuts state completely, deodorant liquid is avoided to flow into mixing chamber 2 to be entered in vacuum pump 23 by suck-back.
