The inlet and outlet points of the pump body are respectively provided with adjustable pipe clips matched with the pump body. The utility model has the advantages of high flow, low pulse, high precision, simple structure and convenient operation.

Description

Pumping flexible working head for dosing packing

The utility model relates to a kind of Wriggling Pump Head, particularly be a kind of quantitative packing Wriggling Pump Head.

The domestic peristaltic pump power that has is little at present, and stream time is short, and is only limited to the conduit that uses a kind of diameter, is subjected to certain limitation on using scope.There is pulse peristaltic pump in itself, and when roller leaves conduit, just have flashy flow velocity and reduce, poor accuracy, precision is low.The peristaltic pump unreasonable structure that has, poor reliability, dangerous.

In view of above reason, the purpose of this utility model is for a kind of high flow capacity is provided, low pulse, and highi degree of accuracy, rational in infrastructure, safe in utilization, the quantitative packing Wriggling Pump Head that reliability is high.

The pump housing that contains import and outlet is arranged in the utility model, place the pump cover on the pump housing, it is characterized in that the runing rest that can be connected with motor is arranged in the pump housing, be symmetrically placed in the molgogger on the runing rest, one end respectively with runing rest and the hinged rocking arm of molgogger, the flattening roller that is loaded on the rocking arm the other end respectively and can rotates, import and export at the pump housing is equipped with the adjustable pipe clip of cooperation with it respectively (referring to Fig. 1, Fig. 2), the rotation of motor can be adopted computer control, adopt molgogger, flatten each two of rollers, can reduce the influence of pulse, keep constant under various conditions, adopt adjustable pipe clip, except that conduit can being fixed, also can adjust arbitrarily according to the different size of conduit.

The diameter of above-mentioned flattening roller is greater than the diameter (referring to Fig. 1) of molgogger.

On the above-mentioned rocking arm adjusting screw is housed, adjusting screw one end is tightly packed in (referring to Fig. 1) on the runing rest, according to the diameter adjustment flattening roller of conduit and the gap of the pump housing, to satisfy different traffic requirements.

Pressure spring (referring to Fig. 1, Fig. 2) is housed respectively between above-mentioned rocking arm and runing rest, keeps the rocking arm stable working.

On the central axis of above-mentioned runing rest mounting hole is arranged, elastic chuck is loaded in the mounting hole, and motor output shaft is loaded in the elastic chuck, and adjusting screw is through on runing rest and the elastic chuck motor output shaft is connected (referring to Fig. 4) with runing rest.

The above-mentioned pump cover and the pump housing hinged (referring to Fig. 1, Fig. 3) can be got easily and change conduit, and pump cover can adopt plexiglass to make, can the sense of rotation of runing rest directly perceived and flowing of liquid.

During work, conduit is installed on the pump housing, the roller of propelling when one section conduit recovers its original shape, produces certain negative pressure with closed catheter in the pipe, liquid is sucked, and this partially liq is promoted forward by second roller subsequently, finally releases from the pump housing.

The utility model can adopt computer control, and drive motor can reduce the influence of pulse, keeps invariable under various conditions.Low pulse, high flow capacity, highi degree of accuracy can be done operation, draws formula certainly and extracts liquid, does not produce adverse current, and liquid is not produced shearing, does not change biochemical property and physical property, and liquid only can not produce any pollution through conduit.Compact structure, reasonable, the reliability height, safe in utilization, but continuous operation 24 hours, the energy stepless time adjustment is from 0～220 rev/min, and speed adjustable range is wide, can change the conduit of different-diameter, various criterion (as abrasive rubber II type according to different usage requirements, biological rubber, silicone rubber, neoprene; styrene butadiene rubber; synthetic rubber, polyethylene etc.), packing at regular time and quantity.Easy to operate, applied range can be widely used in the beverage packing, cell cultivation and fermentation, filtration and separate food processing, Chemical Manufacture, pharmacy, blood product, the industries such as solution and water treatment of taking pictures.The technical performance of the utility model Wriggling Pump Head and safety reliability reach the standard-required of Britain BS800 and International Power member IEC335-1 of committee and IEC34-5.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the assembly relation schematic representation of runing rest and roller.

Referring to Fig. 1～Fig. 4, import 2, outlet 3 are arranged on the pump housing 1, the pump cover 4 and the pump housing 1 that adopt the transparent organic glass material to make are hinged.Runing rest 5 places in the pump housing 1.Molgogger 6,7 symmetries are positioned on the runing rest 5, on the end that hinge

8,9 is through molgogger 6,7 and rocking

arm

10,11 successively and the runing rest 5 molgogger 6,7 are connected with runing rest respectively with rocking arm 10,11.Rotatable flattening roller 12,13 is housed on the other end of rocking

arm

10,11, flattens the diameter phi 2 of the diameter phi 1 of roller greater than molgogger.On the both ends of the surface of runing rest and rocking arm opposite position, scyewed joint adjusting screw 14 and two spring stacks 15 on rocking arm are arranged respectively.

Adjustable pipe clip

18,19 is contained in the just

available spring sheet

25,26 of pump housing import and export to be fixed on the pump housing.

Referring to Fig. 4, flexible dop 28 in the mounting hole 27 of runing rest, the output shaft 29 of motor is loaded in the elastic chuck, and adjusting screw 30 is through on runing rest and the elastic chuck motor output shaft 29 is connected with runing rest.

Automatically during control, adopt monolithic computer program control and high energy permanent magnetism small volume motor and and electronic scale combine together, just can realize the function of quantitative packing.

But the electric rotary switch of manual operation, the control motor speed is finished.
