Description
Technical field
The present invention relates to a kind for the treatment of technology of dry powder bucket in haemodialysis control unit, more particularly, to a kind of haemodialysis control unit
Dry powder bucket purging method.
Background technology
During the use of dry powder bucket, being inside it can be water-filled.And, it is necessary to will be dry after dry powder bucket is used and finished
Powder bucket is removed and abandoned from dry powder frame.Due to having water in dry powder bucket, when dry powder bucket is removed from dry powder frame, water can be from dry powder bucket
In spill, made troubles to operating personnel.
Therefore, before dry powder bucket is removed, it is necessary to empty dry powder bucket, by the water discharge in dry powder bucket, so that convenient operation
Personnel.In current haemodialysis control unit, dry powder bucket emptier is to need to increase the control elements such as magnetic valve just in fluid path
Can realize, cost of implementation is higher.
The content of the invention
To overcome the defect of prior art, the present invention to propose a kind of dry powder bucket purging method of haemodialysis control unit without increasing
Control element and realize simple.
The present invention adopts the following technical scheme that realization：A kind of dry powder bucket purging method of haemodialysis control unit, it includes：
Keep negative pressure pump to rotate, B liquid pipes are taken out from heating chamber, make its water in cannot sucking heating chamber；
Close plunger displacement pump, air removing valve is opened, in the presence of the negative pressure between negative pressure pump and thin footpath joint, make dry powder bucket
Interior water is sequentially passed through except air cavity, air removing valve, negative pressure are pumped into heating chamber；
Wherein, heating chamber connects negative pressure pump by thin footpath joint, and thin footpath joint connects the row except air cavity by air removing valve
Gas port, and the outlet of the liquid inlet connection dry powder bucket of air cavity is removed, and the entrance for connecting dry powder bucket connects heating by B liquid pipes
Chamber, except the liquid outlet of air cavity connects the liquid inlet of plunger displacement pump by pipeline.
Wherein, the dry powder bucket purging method of the haemodialysis control unit also includes：The shape that plunger displacement pump closing, air removing valve are opened
After state maintains setting duration, terminate the emptying process of dry powder bucket.
Wherein, a length of 10s during setting.
Wherein, air removing valve is magnetic valve.
Compared with prior art, the present invention has the advantages that：
The present invention realizes dry powder bucket emptying process using the negative pressure in fluid path, without increasing element in fluid path, realizes letter
Single, cost of implementation is relatively low.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is schematic flow sheet of the invention.
Specific embodiment
As shown in figure 1, the present invention proposes the dry powder bucket for having simple structure, cost of implementation relatively low in haemodialysis control unit
Emptier, it includes：Heating chamber 1；A liquid pipes 2 and B liquid pipes 3 in alternative implantation heating chamber 1 in liquid；B liquid pipes 3 connect
The entrance of the dry powder bucket 5 being fixed on dry powder frame 4 is connect, and the outlet of dry powder bucket 5 is connected except the liquid of air cavity 6 enters by pipeline
Mouthful, and the liquid outlet for removing air cavity 6 connects the liquid inlet of plunger displacement pump 7 by pipeline；And heating chamber 1 passes through a thin footpath joint
10 one negative pressure pump 8 of connection, the thin footpath joint 10 connects the exhaust outlet except air cavity 6 by air removing valve 9.
Rotated when negative pressure pump 8 works, due to the obstruction of thin footpath joint 10, make to have between negative pressure pump 8 and thin footpath joint 10
The negative pressure of certain pressure size, so that the liquid in heating chamber 1 is separated with gas, reaches the purpose of degasification.
In haemodialysis control unit normal work, air removing valve 9 is closed, and by the rotation of plunger displacement pump 7, water is by B liquid pipes 3 from heating
Chamber 1 is extracted out, and mixed liquor is mixed into the B powder in dry powder bucket 5 by dry powder bucket 5, and mixed liquor passes through except air cavity 6 send from plunger displacement pump 7
Go out.
Wherein, air removing valve 9 is magnetic valve.
With reference to shown in Fig. 2, to dry powder bucket 5 carry out emptying process the step of specifically include：
Step S1, holding negative pressure pump 8 are rotated, and B liquid pipes 3 are taken out from heating chamber 1, and allowing it to expose can only inhale in atmosphere
Enter air and the water in heating chamber 1 cannot be sucked.
Step S2, close plunger displacement pump 7, air removing valve 9 is opened, the work of the negative pressure between negative pressure pump 8 and thin footpath joint 10
Under, the water in dry powder bucket 5 is sequentially passed through except air cavity 6, air removing valve 9, the feeding heating chamber 1 of negative pressure pump 8.
Step S3, plunger displacement pump 7 is closed, state that air removing valve 9 is opened maintains setting duration (such as 10s), in postponing to set
After timing is long, closes air removing valve and terminate the emptying process of dry powder bucket 5.
So, the present invention is blotted the water in dry powder bucket 5 using the negative pressure between negative pressure pump 8 and thin footpath joint 10, is reached
The purpose of the emptying of dry powder bucket 5, facilitates operating personnel that dry powder bucket 5 is removed from dry powder frame.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
