Process 1, moisturizing:

Moisturizing process is exactly the step of injecting cleaning solution into cleaning cabin 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 to clean cabin 2 to intake under negative pressure state, opens moisturizing Valve 16 injects cleaning solution into cleaning cabin 2 by inlet pipeline, while vacuum pumping valve 6 is opened, and vacuum pump 29 is opened, and starting is clear Washing of tanks 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 gas broken 8 recovery in (3~5 seconds) of valve cleaning cabin 2 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) under state naturally in injection cleaning cabin 2, 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 clean to retain certain altitude at the top of cabin, cleans cabin at this time 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 for cleaning 2 cleaning liquid inside of cabin is heated to set temperature.Cleaning 2 cleaning liquid inside of cabin 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 cleaning in cabin 2 process being drawn onto vacuum tank 9 that process 3, which is briefly described,.Specific step is as follows:

Moisturizing process 1 and heating process 2 is first carried out, makes to clean the cleaning solution of injection certain altitude in cabin 2, and is heated to Set temperature.It after having executed process 1 and process 2, opens gas and breaks valve 8, make to clean holding normal pressure (0KPa) state on 2 liquid of cabin.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 opposite cleaning 2 presence -90KPa of cabin of vacuum tank 9 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 cleaning cabin 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 cleaning cabin 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 flowing back into the process cleaned in cabin 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 the broken valve 8 of gas for closing and cleaning the connection of cabin 2, opens 29 pairs of cleaning cabins 2 of vacuum pump and vacuumizes, 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 cleaning cabin 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 cleaning cabin 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, cleaning hatchcover 3 is to be in close state, closes gas and break valve 8, makes to clean cabin 2 for closed state.It opens and takes out Vacuum valve 6 and vacuum pump 29, extraction cleaning 2 inner air of cabin.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.It is cleaned between cabin and vacuum tank at this time 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, make to clean the recovery of cabin 2 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 cleaning 2 cleaning liquid inside of cabin 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, start vacuum pump 29, cleaning cabin 2 is taken out Vacuum, in vacuum, the gas cleaned in cabin 2 is extracted, and with being gradually increased for vacuum degree, cleans air pressure in cabin 2 Set vacuum values are progressivelyed reach, the boiling point that cleaning 2 cleaning liquid inside of cabin is generated according to set vacuum values is also decreased, cleaned 2 internal liquid of cabin starts to roll, after pressure sensor 5 reaches setting value, when controlling liquid rolling in cleaning cabin 2 with system time 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 in cleaning cabin 2, and liquid 1902 moment of jet pipe is entered cleaning cabin 2 in vacuum tank 9 It is interior, one powerful scouring force is formed, while driving cleaning 2 cleaning liquid inside of cabin progress is quickly fierce to wash away, when in cleaning cabin 2 Rapidly after multiple pressure, cleaning 2 inner vacuum value of cabin 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.

It is typically repeated changing voltage pulses cleaning process 2-5 times under liquid, fabulous cleaning effect can be played to lumen instrument.It is more One of the characteristics of grade changing voltage pulses cleaning technique is exactly that variation is more, therefore the above-mentioned described numerical value such as pressure value or time are all It can adjust according to the actual situation, be intended only as a kind of introduction of method herein.Such as by controlling transformation arteries and veins under each not good liquor The time that fluid valve 34 is opened under liquid in cleaning process is rushed, so that the liquid supply rate that cabin 2 is cleaned under vacuum negative pressure condition is controlled, thus Keep the impact force injected every time and cleaning force different, so that cleaning ability is obtained effective guarantee, while vacuumizing boiling A large amount of heat can be consumed in the process and reduce the temperature of cleaning solution, limited when cleaning solution temperature in the process of cleaning is reduced to When below fixed minimum temperature, heater 17 can be automatically turned on, to guarantee that cleaning process can be carried out effectively.

Process 7, transformation phase pulse cleaning on multistage liquid:

Specific method is after having executed process 1 and process 2, and cleaning 2 cleaning liquid inside of cabin 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, cleaning cabin 2 is vacuumized, in vacuum, clearly Gas in washing of tanks 2 is extracted, and with being gradually increased for vacuum degree, the air content in cleaning solution cleaned in cabin 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 cleaning cabin 2, due to huge pressure difference, generate bulk gas and pour cleaning cabin 2 It is interior, to the instrument being immersed in cleaning solution formed it is strong wash away, clean cabin 2 in restore normal pressure rapidly.

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.
