Description
Technical field
The utility model relates to chemical apparatuses technical fields, and in particular to a kind of visual box sand core Suction filtration device.
Background technique
Suction filtration has double meaning, and suction filtration, which refers to, in physical term reduces the pressure in bottle,suction using aspiration pump, reaches solid
The purpose method of liquid separation.Existing laboratory Suction filtration device is a bottle,suction, is only used for retaining since water withdrawal is excessive
Suspended matter, directly cannot inside place colorimetric cylinder or volumetric flask filters the device that digestion solution can be obtained.And when filtering, only
A sample can be filtered, bottle,suction is big and is difficult to rinse, needs to clean a bottle,suction after having filtered again, can not achieve multiplicity
Product are filtered simultaneously, and working efficiency is difficult to improve.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of visual box sand core Suction filtration device, to reach simultaneously
Multi-example suction filtration is carried out, the technical effect of working efficiency is improved.
To achieve the above object, the technical solution of the utility model is:
A kind of visual box sand core Suction filtration device, including cabinet and colorimetric tube fixing device, the front of the cabinet are equipped with saturating
Bright sealing cover, the sealing cover are surrounded by seal washer, can directly seal buckle on cabinet, the side of the cabinet is equipped with
Aspirating hole, the box house are equipped with colorimetric cylinder, and the colorimetric cylinder is fixed in cabinet by colorimetric tube fixing device, the cabinet
Top planes are equipped with several equally distributed sealing holes equipped with sealing ring, and the upper end of the cabinet is equipped with several cylindrical sand cores
Case is inserted into across sealing hole in funnel and conical sand core funnel, the outlet of the cylinder sand core funnel and conical sand core funnel
In intracorporal colorimetric cylinder.
Further, the cabinet is trapezoidal, and each case angle of cabinet is arc angling.
Further, volumetric flask or conical flask are additionally provided in the cabinet.
The utility model compared with prior art, the beneficial effect is that:
The utility model can directly put colorimetric cylinder, volumetric flask or conical flask in case, and it is with a scale that different type may be selected
Sand core funnel can be filtered in the lab according to the volume of sample solution.Meet simultaneously filter it is a small amount of or batch
Sample filters overall process, is all transparent visual, can accurately hold the water of rinse resolution bottle.Especially for environmental classes without press proof
Product (solid waste leachate, filter cylinder, filter membrane, deposit etc.) digestion solution carries out batch rapid filtration under suction, need to only be moistened with a small amount of pure water
Constant volume is washed, does not need to repeat to clear up and closely do, more traditional filtering has the time short, and work efficiency is high, and recovery of standard addition is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model sealing cover；
The meaning of appended drawing reference in figure: 1, cylindrical sand core funnel, 2, sealing hole, 3, aspirating hole, 4, colorimetric cylinder, 5, circular cone
Shape sand core funnel, 6, cabinet, 7, sealing cover, 8, colorimetric tube fixing device.
Specific embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment 1:
A kind of visual box sand core Suction filtration device, including cabinet 6 and colorimetric tube fixing device 8, the front of the cabinet 6 are equipped with
Transparent sealing cover 7, the sealing cover 7 are surrounded by seal washer, can directly seal buckle on cabinet 6, the one of the cabinet 6
Side is equipped with aspirating hole 3, and the box house is equipped with colorimetric cylinder 4, and the colorimetric cylinder 4 is fixed on cabinet 6 by colorimetric tube fixing device 8
Interior, 6 top planes of cabinet are equipped with several equally distributed sealing holes 2 equipped with sealing ring, and the upper end of the cabinet 6 is equipped with
Several cylinder sand core funnels 1 and conical sand core funnel 5, the cylinder sand core funnel 1 and conical sand core funnel 5 go out
Mouth passes through sealing hole 2 and is inserted into the colorimetric cylinder 4 in cabinet 6.
Wherein, the cabinet 6 is trapezoidal, and each case angle of the cabinet 6 is arc angling.Appearance is additionally provided in the cabinet 6
Measuring bottle or conical flask.
In use, firstly, colorimetric cylinder 4, volumetric flask or conical flask are put into cabinet 6, then with cylindrical sand core funnel 1
Or conical sand core funnel 5 passes through colorimetric cylinder 4, volumetric flask or the conical flask inside sealing hole connection, followed by sealing
7 seal case 6 of lid.
Secondly, trimming filter paper, it is slightly less than funnel, but all holes are all covered, and distilled water is added dropwise to make to filter
Paper is completely embedded with funnel.
Finally, being vacuumized finally by aspiration pump connection aspirating hole 3 to cabinet 6, pumping switch pump is opened, starts to take out
Filter.
For above-described embodiment simply to illustrate that the technical ideas and features of the present invention, its purpose is allows this field
Interior those of ordinary skill can understand the content of the utility model and implement accordingly, can not limit the utility model with this
Protection scope.The equivalent changes or modifications that all essence according to the content of the present invention is made, should all cover in this reality
With in novel protection scope.
