Abstract
The utility model relates to a small centrifugal filter which comprises a filtering liquor receiving vessel and a rotatable pezizoid filtering component arranged in the filtering liquor receiving vessel, wherein, the filtering component has an internal surface which can support filtering media, and at least the position of the side wall of the filtering component has a through filtering hole; the lower part of the filtering component is provided with a coupling structure, the coupling structure is locked and connected with a rotating shaft, and the rotating shaft which is arranged at the bottom of the filtering liquor receiving vessel can be driven by a drive mechanism to rotate along a vertical axial cord.
Description
The utility model relates to a kind of centrifugal filter device, particularly be suitable for the small-sized filter that the laboratory is used.
Filtration is one of several operations the most frequent in the many laboratories, particularly chemical laboratory, and the instrument that tradition is used is the funnel of variety classes such as conical hopper, Buchner funnel, sintered filter funnel and form; Reliable liquid gravity natural filtration of mode of operation and the outer forms such as suction filtration that add negative pressure.For the funnel instrument, limit by its version as Buchner funnel, the molten funnel that hangs down etc., some position almost can't directly be cleaned, and is a scabrous problem.For the negative pressure leaching mode, not only equipment needed thereby is many, and volume is big, expense height, and regular meeting runs into contaminated equipment or pressure irregular variation, even cause and accident such as pour in down a chimney.
The purpose of this utility model is to provide a kind of small-sized centrifugal filter device that the laboratory is used that is particularly suitable at the problems referred to above.
The utility model filter includes the filtrate receiving vessel and is arranged on interior two the primary structure parts of rotatable cup-shaped filtration members of this container.But wherein rotatable cup-shaped filtration members has a support filter medium, as the inner surface of typing medium such as filter paper, filter cloth or unformed medium such as active carbon, diatomite, and the filter opening of some connectivities should be arranged at its sidewall position at least.Certainly, also can adopt similar sintered filter funnel such, this inner surface and filter medium and filter opening are all made overall structure form, be divided into the typing series filtration members of different model again by filter opening size in volume and/or the medium.The bottom of said above-mentioned rotatable filtration members has bottom being in the filtrate receiving vessel and can--motor or hand-operated mechanism etc.--drive be connected along the rotating shaft do locking that vertical axis rotates by driving mechanism, so that the draw bail that maintenance is driven to rotate.This draw bail can adopt versions such as having spiral, card, folder, also can adopt frosted joint-interface structure form commonly used in the laboratory when rotating speed is very not high, purpose is to make filtration members both can closely cooperate with rotating shaft and is driven to rotate, can be separated with rotating shaft again, to clear up filter residue and to carry out feelings and wash.Driving mechanism can be located in the filtrate receiving vessel or outer any suitable position, cooperate with the rotating shaft connection through transmission mechanism, being provided in a side of below this container of most convenient, pass container bottom and connect (this moment, the suitable seal structure was necessary certainly) with rotating shaft, can reach simple in structure and the little effect of volume.In case of necessity, the tap hole that a band valve is set at the minimum position of filtrate receiving vessel bottom is desirable, helps the taking-up of filtrate.During use, different rotating speeds according to rotating shaft--can regulate or the manual operation adjusting by motor, the cup-shaped filtration members is driven to rotate, the liquid that is filtered in the material wherein throws away the filtrate receiving vessel with the filter opening of different speed from sidewall under centrifugal action, and filter residue retains in the filter medium surface of filtration members inwall.The advantage of this device is that not only filter efficiency is high and be convenient to wash filter residue, and structure all greatly simplifies than various vacuum shafts filter equipment, also is convenient to the cleaning of parts, does not have the position, dead angle that can't clean.The unsafe factor that may occur when also having avoided simultaneously present various vacuum filtration.
Below structure of the present utility model is described, but it should be interpreted as it is qualification the above-mentioned subject area of the utility model with example shown in the drawings.
Fig. 1 structure of the present utility model
As shown in the figure, this example is with motor-driven small-sized centrifugal filter device, is provided with rotatable filter cup 3 in filtrate receiving vessel 2, and its inner surface 1 is a filter medium support face, and many connectivity filter openings 8 are arranged on the sidewall.5 of the rotating shafts of the bottom of filter cup 3 bottoms and filtrate receiving vessel 2 have frosted joint-interface formula draw bail 4.Be provided with the motor 7 of band arrangements for speed regulation in the base, the arbor of its vertical axis passes filtrate receiving vessel 2 diapires and connects with rotating shaft 5.Be provided with the leakage fluid dram 6 of a band valve at the lowest part of this filtrate receiving vessel.Filter cup 3 wherein can be made into has not isometric serial refill-unit form, choosing when easy to use.
Claims (3)
1, a kind of small-sized centrifugal filter device with the filtration spare that has filter opening, it is characterized in that including filtrate receiving vessel (2) and be arranged on interior rotatable cup-shaped filtration members (3) two-part structure of this container, filtration members (3) but have the inner surface (1) of a support filter medium, and the filter opening (8) that connectivity should be arranged at its sidewall position at least, its underpart have and are in the draw bail (4) that filtrate receiving vessel (2) bottom can be connected by rotating shaft (5) the do locking that the driving mechanism drive is rotated along vertical axis.
2, device as claimed in claim 1 is characterized in that between the draw bail (4) of said filtration members (3) bottom and rotating shaft (5) fit structure for the taper frosted joint-interface shape that not only can closely cooperate mutually but also can be separated from each other.
3, device as claimed in claim 1 or 2 is characterized in that the minimum position in said filtrate receiving vessel (2) bottom is provided with the tap hole (6) of band valve.
