Abstract
The utility model discloses a dry powder barrel emptying device used for a hemodialysis machine. The dry powder barrel emptying device comprises a heating cavity and a negative pressure pump, wherein the negative pressure pump is connected with the heating cavity through a thin joint connected with an exhaust port of an air removing cavity through an air removing valve, a liquid inlet of the air removing cavity is connected with an outlet of a dry powder barrel, and a B liquid tube connected with an inlet of the dry powder barrel is arranged outside the heating cavity. When a plunger pump is turned off and the air removing valve is opened, under the action of negative pressure between the negative pressure pump and the thin joint, water in the dry powder barrel passes through the air removing cavity, the air removing valve and the negative pressure pump in sequence, so as to be sent into the heating cavity, therefore the water in the dry powder barrel is sucked up, the purpose of emptying the dry powder barrel is achieved, and operating personnel can conveniently take down the dry powder barrel from a dry powder rack. According to the dry powder barrel emptying device, the negative pressure on a liquid path is utilized to empty the dry powder barrel, no element is additionally arranged on the liquid path, and the dry powder barrel emptying device has the advantages of simple structure and lower implementation cost.
Description
Technical field
This utility model relates to a kind of parts of haemodialysis control unit, especially relates to a kind of dry powder bucket emptier for haemodialysis control unit.
Background technology
In the use procedure of dry powder bucket, its inside is can be water-filled.And after the dry powder bucket is finished using, the dry powder bucket need to be taken off and abandons from the dry powder frame.Owing in the dry powder bucket, water being arranged, when the dry powder bucket was taken off from the dry powder frame, water can spill from the dry powder bucket, makes troubles to operator.
Therefore, before taking off the dry powder bucket, need emptying dry powder bucket, the water in the dry powder bucket is discharged, thus the handled easily personnel.In present haemodialysis control unit, dry powder bucket emptier is need to increase the control element such as electromagnetic valve could realize on the liquid road, realizes that cost is higher.
The utility model content
For overcoming the defective of prior art, the utility model proposes a kind of simple in structure for haemodialysis control unit, realize lower-cost dry powder bucket emptier.
This utility model adopts following technical scheme to realize: a kind of dry powder bucket emptier for haemodialysis control unit, and it comprises: heating chamber; The negative pressure pump that connects heating chamber by thin drive connector; And thin drive connector connects the air vent that removes air cavity by air removing valve, and connects the outlet of dry powder bucket except the liquid inlet of air cavity, and the B liquid pipe of the entrance of connection dry powder bucket is placed in outside heating chamber.
Wherein, the liquid outlet except air cavity connects the liquid inlet of plunger displacement pump by pipeline.
Wherein, air removing valve is electromagnetic valve.
Compared with prior art, the utlity model has following beneficial effect:
This utility model utilizes the negative pressure on the liquid road to realize that the dry powder bucket is emptying, and need not increases element on the liquid road, and is simple in structure, realizes that cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model proposes for haemodialysis control unit have simple in structure, realize lower-cost dry powder bucket emptier, it comprises: heating chamber 1; A liquid pipe 2 and B liquid pipe 3 in alternative implantation heating chamber 1 in liquid; B liquid pipe 3 is fastened on the entrance of the dry powder bucket 5 on dry powder frame 4, and the outlet of dry powder bucket 5 connects liquid inlet except air cavity 6 by pipeline, and connects the liquid inlet of plunger displacement pump 7 by pipeline except the liquid outlet of air cavity 6; And heating chamber 1 connects a negative pressure pump 8 by a thin drive connector 10, the air vent that this thin drive connector 10 connects except air cavity 6 by air removing valve 9.
Rotate during negative pressure pump 8 work, due to the obstruction of thin drive connector 10, make between negative pressure pump 8 and thin drive connector 10 to have the negative pressure of certain pressure size, thereby make the liquid in heating chamber 1 separated from the gas, reach the purpose of degasification.
When haemodialysis control unit worked, air removing valve 9 was closed, and by the rotation of plunger displacement pump 7, water is extracted out from heating chamber 1 by B liquid pipe 3, and the B powder interior through dry powder bucket 5 and dry powder bucket 5 is mixed into mixed liquor, and mixed liquor is through sending from plunger displacement pump 7 except air cavity 6.
When needs carry out when emptying dry powder bucket 5, keep negative pressure pump 8 to rotate, B liquid pipe 3 is taken out from heating chamber 1, allowing it be exposed in air outward can only air amount and can't suck water in heating chamber 1; Then, make that plunger displacement pump 7 cuts out, air removing valve 9 is opened, under the effect of the negative pressure between negative pressure pump 8 and thin drive connector 10, water in dry powder bucket 5 is successively through sending into heating chamber 1 except air cavity 6, air removing valve 9, negative pressure pump 8, thereby the water in dry powder bucket 5 is blotted, reach the emptying purpose of dry powder bucket 5, the handled easily personnel take off dry powder bucket 5 from the dry powder frame.
Wherein, air removing valve 9 is electromagnetic valve.
The above is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. a dry powder bucket emptier that is used for haemodialysis control unit, is characterized in that, comprising: heating chamber; The negative pressure pump that connects heating chamber by thin drive connector; And thin drive connector connects the air vent that removes air cavity by air removing valve, and connects the outlet of dry powder bucket except the liquid inlet of air cavity, and the B liquid pipe of the entrance of connection dry powder bucket is placed in outside heating chamber.
2. be used for according to claim 1 the dry powder bucket emptier of haemodialysis control unit, it is characterized in that, the liquid outlet that removes air cavity connects the liquid inlet of plunger displacement pump by pipeline.
