Abstract
A cleaning treatment device of medical or pharmaceutical rubber stopper can effectively reduce surface insoluble particles. The theory is that the rubber stopper can be cleaned when floating or half floating by high pressure liquid flow from the above. The device comprises a container, a cleaning tank, a water storing bucket, a water inlet pipe and water outlet pipe. The characteristics lie in that pluralities of water spray holes are positioned on the bottom or sides of the container and that back-flow grooves and holes are arranged on the bottom. Cleaning water is sprayed out of the spray holes at a certain pressure through the pressurization pump the pressure adjusting valve. When cleaned, the rubber stopper is floating or half floating so dynamic cleaning is realized and friction between rubber stoppers is avoided.
Description
Technical field
The present invention relates to a kind of cleaning processing apparatus that can effectively reduce the medical or medicinal rubber stopper of surperficial particulate matter.
Background technology
Current rubber stopper (hereinafter to be referred as plug) with vulcanized rubber (comprising the various vulcanizates based on butyl rubber, natural rubber, isoamyl glue, acrylonitrile-butadiene rubber etc.) is widely used in the peristome of the medical or pharmaceutical containers of shutoff, this is because the rubber high resilience can produce functions such as remarkable sealing, shroud of gas, anti-acupuncture to the content of container.But because its technological process of production will comprise multiple working procedures such as mixing, moulding, sulfuration, die-cut, deburring, check, packing, the plug surface is very easy in the handover process of each procedure adheres to and is infected with various insoluble impurities particulates.For content medical or that pharmaceutical containers held,, can't permit the contamination of this based fine particles owing to maintaining the health even the life of human body.Before in the end packing, medical for this reason or medical rubber plug all to pass through washing procedure, to remove surperficial particulate matter.
Cleaning device at present commonly used has two kinds of roller and basket-hangings.
Roller is in a container that holds certain water gaging or cleaning solution, a rotating drum is set, arranges on the drum wall and can supply water or hole that cleaning solution flows through, plug is placed in the drum, by the rotation of drum in water or cleaning solution, reach the purpose of cleaning.This method utilization is arranged on the valve of container bottom, can be according to water and the cleaning solution in the needs of the technology transposing container, thereby can be to repeatedly cleaning with batch plug.The shortcoming of this method is: 1, impurity content and density unevenness are even in water in the drum or the cleaning solution; Plug was in contact with one another friction when 2, drum rotated, and produced new particulate matter; But though 3, water or cleaning solution reflux and filter after cleaning, removal of contamination is to the pollution once more of plug fully.
Basket-hanging is to arrange side by side that several hold the container of clear water or cleaning solution, and plug places and hangs indigo plant, by hanging basket in each container one by one lixiviate move, finish the washing and cleaning operation of plug.Though this method can avoid plug to be in contact with one another the friction and the repeated contamination of cleaning fluid, still, its shortcoming is, 1, plug immerses in the cleaning fluid under static conditions, and whole cleaning performance is undesirable; 2, inconsistent in hanging basket centre and border area cleaning performance between the two, particularly the plug at zone line can not get effective washing.
Summary of the invention
Because the shortcoming of above-mentioned cleaning device, the present invention aim to provide a kind of in cleaning process plug can not be in contact with one another cleaning treatment method and the device that friction can wash away and take away the medical or medicinal rubber stopper of particulate matter again with dynamic current flow.
The utility model system promptly adopts high pressure liquid stream to wash away rubber stopper from bottom to top based on the principle that the liquid that adopts band pressure impacts washing, makes rubber stopper finish cleaning treatment when being in half suspension and suspended state.
For this reason specialized designs by the device of the medical or medicinal rubber stopper of this cleaning treatment principle cleaning treatment, constitute and comprise container, washing tank, water butt, water inlet pipe, outlet pipe, it is characterized in that, the bottom of described container and side wall array hole for water spraying, the bottom also is placed with backflash or return port.When cleaning plug, plug places in the washing tank, from the cleaning solution of water inlet pipe inflow, after the booster pump supercharging, act on plug from the liquid stream of water jet ejection band certain pressure, make plug be subjected to washing away, constantly be in half and suspend and suspended state, simultaneously by backflash or return port from the fluid power of bottom and side, install after filtration, extract out by the liquid of suction pump after, return water storing tank, recycle Washing.Discharge for the liquid stream after making particulate matter with washing, avoid polluting once more plug, guarantee to clean thoroughly, on inlet pipeline, connect pressure regulator valve, can regulate pressure regulator valve, make feed liquor flow V
1≤ go out flow quantity V
2
Container can be cylinder and the cube of bottom for arc and plane, and for the flow stream pressure that makes ejection is evenly distributed, the hole for water spraying that is arranged in its bottom and sidewall should be staggered, and the distance between borehole between the hole for water spraying is represented to be preferably with three hole inscribe diameter of a circles:
Bottom hole for water spraying pitch of holes: D
1=1/4d
1～3/4d
1,
Sidewall hole for water spraying pitch of holes: D
2=d
1～3d
1,
The hole for water spraying aperture is preferably: D
3=1/10d
1～3d

In the formula: D
1---three hole inscribed circle diameters in the bottom;
D
2---at three hole inscribed circle diameters of sidewall;
D
3---the hole for water spraying aperture;
d
1---the biggest size of element of plug.
The hole for water spraying pitch of holes is too small, causes backflash and return port to be difficult for arranging, so that discharge opeing is not smooth, otherwise pitch of holes is excessive, can cause hydraulic pressure not enough and uneven, even plug can not be in half suspension and suspended state.The hole for water spraying aperture is excessive or too smallly all can cause the flow stream pressure deficiency, can not make plug be in desirable half and suspend and suspended state, so that cleaning performance is affected.
For the particulate matter that washes away is taken away by liquid stream smoothly, arrange in the bottom of container backflash or return port, the groove width H of backflash
1Or the aperture D of return port
4Be preferably:
Groove width H

In the formula; h
1---the plug height;
d
2---the glue stopper neck physical dimension.
It is conspicuous adopting effect of the present utility model, that is:
1, plug is subjected to washing away of certain pressure liquid stream and washes, and can effectively reach the effect of flush away insoluble impurities particulate;
2, plug constantly is in half suspension and suspended state, is subjected to the impact from bottom and side liquid stream simultaneously, and under dynamic situation, the plug surface can evenly be washed, and every batch of cleaning performance is even;
3, be in half at the effect bottom plug of liquid stream scouring force and suspend and suspended state, significantly reduce it and be in contact with one another friction and the chance that produces new contaminant particles;
4, the liquid after the washing is forced to extract out and discharges, and takes away the contaminant particles of getting off from surface washing, has avoided the pollution once more to plug.
