As shown in fig. 6, being a kind of cleaning method of stage variable pressure pulse cleaner of the application, respectively moisturizing is heated, Vacuum pulse tank is taken out, and vacuum pulse pumpback and lumen internal pulses air-blowing five are most of.First during statement described below, do not have The system being described to then is considered for closed state.

Process 1, moisturizing:

Moisturizing process is exactly the step of injecting cleaning solution into vacuum tank 2 from water compensating valve 16.It is divided into vacuum feed and normal pressure Moisturizing both of which can select according to the actual situation.Vacuum feed is exactly that vacuum tank 2 is intake under negative pressure state, opens moisturizing Valve 16 injects cleaning solution into vacuum tank 2 by inlet pipeline, while vacuum pumping valve 6 is opened, and vacuum pump 29 is opened, and starting is true Empty slot vacuuming action makes groove body keep negative pressure (- 80Kpa or so) state.In the case where groove body is negative pressure state, on the outside of inlet valve Water will accelerate speed and inject toward rinse bath, and moisturizing efficiency can be improved.Water compensating valve 16 is closed when cleaning solution reaches at high liquid level 11 Stop moisturizing, while being also switched off vacuum pumping valve 6, stops vacuum pump 29.And it opens broken 8 (3~5 seconds) the recovery vacuum tanks 2 of valve of gas and is Normal pressure state completes entire vacuum feed process.

It the use of normal pressure moisturizing specific method is to open simultaneously the gentle broken valve 8 of water compensating valve 16, (0KPa is left in normal pressure for cleaning solution It is right) it is injected in vacuum tank 2 naturally under state, the gentle broken valve of water compensating valve 16 is closed when cleaning solution reaches the height of high liquid level 11 8, complete moisturizing process.

The cleaning solution of injection needs to submerge article-cleaning, but needs and retain certain altitude at the top of vacuum tank, at this time vacuum tank According to liquid level be divided under liquid and liquid on.Cleaning solution can be pure water, tap water, and softened water can also add various special Use cleaning agent.

Process 2, heating:

The step of temperature of 2 cleaning liquid inside of vacuum tank is heated to set temperature.2 cleaning liquid inside of vacuum tank is more than low first Just allow heater 17 when the height of liquid level 13, temperature sensor 18 reads the real time temperature of cleaning solution, cleaning solution temperature Stop heating when at or above set temperature, starts heater 17 when being lower than set temperature, stablize cleaning solution temperature Set temperature or so, heating stepses can be according to the set temperatures of variation through in whole service beat, other steps are not having Body states heating process.Heater 17 can be the modes such as electric heating or steam heating, be also possible to the heating of arbitrary shape Device.

Process 3, vacuum pulse tank are taken out:

It is exactly cleaning solution by the process that is drawn onto vacuum tank 9 in vacuum tank 2 that process 3, which is briefly described,.Specific step is as follows:

Moisturizing process 1 and heating process 2 is first carried out, makes the cleaning solution of injection certain altitude in vacuum tank 2, and is heated to Set temperature.It after having executed process 1 and process 2, opens gas and breaks valve 8, make to keep normal pressure (0KPa) state on 2 liquid of vacuum tank.It opens Dynamic vacuum pump 29 opens left arteries and veins after reaching setting time (20 seconds) or setting pressure (- 90KPa) to 9 pumping high vacuum of vacuum tank Rush valve 12 (3-6 seconds), because of the pressure difference of 9 relative vacuum slot of vacuum tank, 2 presence -90KPa or so, according to liquid from high pressure toward low The principle flowed at pressure, being immersed in the cleaning solution inside the lumen instrument in cleaning solution will be inhaled by the vacuum of 2 the inside of vacuum tank Leading-in device 14 pours in vacuum tank 9 quickly through left pulse valve 12, because pressure difference is big, the cleaning solution inside lumen instrument is such as arteries and veins Punching is the same quickly to be injected in vacuum tank 9 in a very short period of time, and powerful scouring force is generated in flow process by the dirt inside lumen Stain is taken away, therefore plays efficient cleaning effect.After the left opening of pulse valve 12 reaches setting time, left pulse valve 12 is closed, and Stop vacuum pump 29, after delay 2 seconds, opens the broken valve 7 of tank gas and tank drain valve 28 exhausts the cleaning solution in vacuum tank 9.Arrive this The left side vacuum pulse tank for completing a process takes out step.Same principle, after vacuum tank replenishes cleaning solution, in repetition It states the movement right side vacuum pulse tank that only left pulse valve 12 is changed to right pulse valve 15 then and can similarly complete a process and takes out step. Left side vacuum pulse tank is taken out and right side vacuum pulse tank pumping is alternately performed, and terminates entire vacuum pulse tank pumping after reaching setting number Step.

Process 4, vacuum pulse pumpback

It is exactly cleaning solution by the process that is flowed back into vacuum tank 2 in vacuum tank 9 that process 4, which is briefly described,.Specific step is as follows:

After process 3 has been first carried out, process 4, vacuum pulse pumpback cleaning can be carried out if selection vacuum tank does not drain Step.

Specific method is to close the gas connected with vacuum tank 2 to break valve 8, opens vacuum pump 29 and vacuumizes to vacuum tank 2, reaches To after setting vacuum degree (- 80KPa), then it is delayed 10 seconds.Opening broken pot valve 7 makes vacuum tank 9 keep normal pressure state, as long as beating at this time Left pulse valve 12 is opened, cleaning solution passes through vacuum suction device by left pulse valve 12 under differential pressure action in vacuum tank 9, then leads to It crosses interface and is diverted to inside each lumen and return in vacuum tank 2, because pressure difference is big flow velocity is fast, have ratio to lumen inside The spot being attached to inside lumen is taken away, plays cleaning action by stronger scouring effect.Similarly, if above-mentioned movement is by a left side Pulse valve 12, which is changed to right pulse valve 15 then, can equally complete the right side vacuum pulse tank pumping step an of process.If executing process 4, then process 3 is drained without tank, makes cleaning solution between vacuum tank 2 and vacuum tank 9 so process 3 and process 4 can be alternately performed It washes away back and forth, is not necessarily to additional additional clean liquid, reaches more energy efficient more efficient cleaning purpose.

Process 5, lumen internal pulses air-blowing

Firstly, vacuum slot cover 3 is to be in close state, closes gas and break valve 8, make vacuum tank 2 for closed state.It opens and takes out Vacuum valve 6 and vacuum pump 29 extract 2 inner air of vacuum tank out.Reach setting time (such as 20 seconds) or setup pressure value (as- After 90KPa), vacuum pump 29 and vacuum pumping valve 6 are closed.Opening broken pot valve 7 at this time makes vacuum tank 9 keep normal pressure (0KPa), delay Left pulse valve 12 is opened after 3 seconds.At this time between vacuum tank and vacuum tank there are bigger pressure difference, such as the principle of giant, Open left pulse valve 12 in a flash, air quickly pours into the cleaning solution squeezed away inside lumen inside lumen instrument, left pulse valve It is closed after opening 2 seconds, and opens gas at once and break valve 8, so that vacuum tank 2 is restored normal pressure, the intracavitary portion of normal pressure state down tube is squeezed away Cleaning solution backfills rapidly the place occupied by air again, this flowing having a try, which is brought, bigger inside lumen washes away effect It answers, plays the effect in the intracavitary portion of cleaning pipe.Same principle repeats the above steps, and left pulse valve, which is changed to right pulse valve, can then replace Execute the lumen internal pulses air-blowing step of left and right side.Terminate entire lumen internal pulses air-blowing stream after reaching setting number Journey.

The technical process that entire embodiment 1 is then completed after process 5 is executed, the present embodiment 1 mainly introduces process 1 to work The process flow of sequence 5 can add peripheral step according to the actual situation, these steps, which are not limited to, to be applied in the cleaning process stage, It may be used in other techniques such as prewashing technique, rinsing process.

The position of each system or function can also be adjusted according to the actual situation.

Cleaning method introduction primarily directed to all kinds of non-intubation instruments below but the cleaning that also can be used as intubation class instrument.

Moisturizing process and heating process are identical as above-mentioned cleaning method, are not repeating to state herein, other processes are as follows.

Process 6, changing voltage pulses clean under multistage liquid:

Specific method is after having executed process 1 and process 2, and 2 cleaning liquid inside of vacuum tank reaches at high liquid level 11 and temperature The temperature that sensor 11 detects reaches set temperature.Then start to execute changing voltage pulses cleaning process under multistage liquid.

After temperature reaches set temperature, firstly, opening vacuum pumping valve 6, starts vacuum pump 29, vacuum tank 2 is taken out Vacuum, in vacuum, the gas in vacuum tank 2 is extracted, with being gradually increased for vacuum degree, air pressure in vacuum tank 2 Set vacuum values are progressivelyed reach, the boiling point that 2 cleaning liquid inside of vacuum tank is generated according to set vacuum values also decreases, vacuum 2 internal liquid of slot starts to roll, after pressure sensor 5 reaches setting value, when being rolled with liquid in system time control vacuum tank 2 Between, open liquid under fluid valve 34,1 second~30 seconds, external atmosphere pressure with filter 20 through tank break valve 7 suck vacuum tank 9 liquid On face, keep balancing with ambient pressure, liquid quickly enters jet pipe 1902 in vacuum tank 9, and jet pipe 1902 is at " out " word Shape or honeycomb are uniformly fixed on the bottom of vacuum tank 2, and liquid enters vacuum tank 2 through 1902 moment of jet pipe in vacuum tank 9 It is interior, one powerful scouring force is formed, while driving the progress of 2 cleaning liquid inside of vacuum tank is quickly fierce to wash away, when in vacuum tank 2 Rapidly after multiple pressure, 2 inner vacuum value of vacuum tank restores normal pressure.

According to the observation we have found that being successively more able to satisfy not using changing voltage pulses cleaning under progress liquid under a variety of negative pressure states With instrument or instrument different parts cleaning requirement, herein we first will setting pressure be successively assigned a value of -60KPa, - 80KPa and three pressure ratings of -100KPa, are repeated in changing voltage pulses cleaning process under above-mentioned liquid, different pressure levels Changing voltage pulses scavenging period is 1-5 seconds, 3-8 seconds, 9-15 seconds, 12-20 seconds, 20-30 seconds, and the execution of different interval is exactly multistage liquid The basic principle of lower changing voltage pulses cleaning technique.

Process 7, transformation phase pulse cleaning on multistage liquid:

Specific method is after having executed process 1 and process 2, and 2 cleaning liquid inside of vacuum tank reaches at high liquid level 11 and temperature The temperature that sensor 11 detects reaches set temperature.Then start to execute transformation phase pulse cleaning process on multistage liquid.

Firstly, opening vacuum pumping valve 6, vacuum pump 29 is opened, vacuum tank 2 is vacuumized, in vacuum, very Gas in empty slot 2 is extracted, and with being gradually increased for vacuum degree, the air content in cleaning solution in vacuum tank 2 gradually subtracts Less and with then part boiling phenomenon, after pressure sensor 5 detects that pressure reaches setting pressure and maintains a period of time, this When open gas and break valve 8 because being negative pressure state in vacuum tank 2, due to huge pressure difference, generate bulk gas and pour vacuum tank 2 It is interior, to the instrument being immersed in cleaning solution formed it is strong wash away, restore normal pressure rapidly in vacuum tank 2.

According to the observation it was found that under different pressures liquid level pour into air generation number of bubbles and play intensity it is different, Successively using carrying out changing voltage pulses cleaning on liquid is more able to satisfy different instruments or instrument different parts under a variety of negative pressure states Cleaning requirement, herein we first will setting pressure be successively assigned a value of three pressure of -100KPa, -120KPa and -150KPa etc. Grade, is repeated in changing voltage pulses cleaning process on above-mentioned liquid, the liquid phase pulse cleaning of different pressure levels 1-5 seconds, 3-8 seconds, 9-15 seconds, 12-20 seconds, 20-30 seconds, the execution of different interval are exactly the basic principle of changing voltage pulses cleaning technique on multistage liquid.

It is typically repeated changing voltage pulses cleaning process 2-5 times on liquid, fabulous cleaning effect can be played to lumen instrument.It is more It is exactly that variation is more, therefore above-mentioned described pressure value or time etc. count one of the characteristics of changing voltage pulses cleaning technique on grade liquid Value can all adjust according to the actual situation, be intended only as a kind of introduction of method herein, for example become on each not good liquor by controlling Gas during pulse cleaning is pressed to break the time that valve 8 is opened, the number of bubbles and play generated when to controlling cleaning solution bumping is strong Degree makes cleaning ability obtain effective guarantee to guarantee not cause instrument shift position to damage because stirring excessively.
