Abstract
The utility model discloses a vacuum suction filter for doing chemical analysis in the laboratory, comprising a container; wherein the upper part of the container has a liquid filtering orifice and a connector connected with a vacuum pump; the lower part of the container has a liquid level controller and a vacuum unilateral valve; wherein the liquid level controller comprises a shield and an a hydraulic control tube in the shield; thehydraulic control tube is connected with the inlet end of the vacuum unilateral valve and the outlet of the vacuum unilateral valve is communicated to the outside of the container. If the vacuum pump stops working and the liquid level is higher than the height of the hydraulic control tube, the redundant liquid will automatically be discharged out through the vacuum one way valve. Therefore, the operation is easy and the work efficiency can be improved.
Description
Technical field:
The utility model relates to a kind of laboratory and does the vacuumfilter that chemical analysis is used.
Background technology:
At present to do the vacuumfilter that chemical analysis uses be a glass triangle bottle in the laboratory, this triangular flask top has filtrate inlet, a joint that is connected with vavuum pump, filtrate enters in the triangular flask by the vacuum draft fast, after liquid in the bottle raises gradually, vacuum draft meeting reduces gradually, therefore liquid will be poured out when liquid level arrives certain altitude, so operating efficiency reduces relatively, operation is also inconvenient.The glass triangle bottle is frangible explosive in addition, has the hidden danger of harm operator personal safety.
The utility model content:
In order to overcome the prior art above shortcomings, the purpose of this utility model is to provide a kind of operating efficiency higher, easy to operate vacuumfilter.
The technical solution adopted in the utility model is: it comprises a container, this container top has liquid filter mouth, a joint that is connected with vavuum pump, the bottom has a liquid-level controller, a vacuum check valve in the container, wherein liquid-level controller is made up of the hydraulic control pipe in device cover and the device cover, the hydraulic control pipe links to each other with the entrance point of vacuum check valve, and the outlet of vacuum check valve passes to outside the container.
In order to adapt to the different requirements of the different solutions rate of filtration, and know vacuum in the container at any time, a vacuum breaker, a vacuum dial gauge also are equipped with in container top.
Described filtrate inlet has embedded a crucible suction filtration base, and this base communicates with container cavity with its filter screen.
In order to make the utility model not easily broken, described each parts all adopt plastics to make.
Owing to the utlity model has liquid-level controller and vacuum check valve, when vavuum pump quits work and liquid level when surpassing hydraulic control pipe height, excess liquid just can be discharged by vacuum check valve automatically, and is so not only easy to operate, and operating efficiency is improved.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, the utility model comprises container 1, in the present embodiment, this container is made up of casing 2, case lid 3, be equipped with on the case lid 3 crucible suction filtration base 4, vacuum pump adapter 5, vacuum breaker 6, wherein the bottom of crucible suction filtration base 4 are filter screens with casing 2 in communicate, vacuum pump adapter 5 is the three way type joint, one communicates with casing 2, one is connected with vacuum meter 7, and the other end is connected with vavuum pump; Vacuum breaker 6 has a spool 6a, have atmosphere input hole 6b in this spool, rise spool 6a communicates atmosphere input hole 6b and the outer atmosphere of container and atmosphere is delivered in the casing 2, adjusting by this valve, can regulate vacuum in the casing 2, to satisfy the different requirements of different liquids the rate of filtration.Also illustrate among the figure, the below is equipped with vacuum check valve 8, liquid-level controller 9, this liquid-level controller 9 and is made up of the hydraulic control pipe 9b in device cover 9a and the device cover 9a in the casing 2, hydraulic control pipe 9b links to each other with vacuum check valve 8 entrance points, and vacuum check valve 8 outlets communicate with casing 2 outer atmosphere.When vavuum pump began to vacuumize, solution entered in the casing 2 by crucible suction filtration base 4, because the effect of vacuum draft, vacuum check valve 8 can be closed automatically, made to keep vacuum in the casing 2, and solution can average rate filter.Vavuum pump quits work, be in antivacuum state in the casing 2, this moment, vacuum check valve 8 was opened automatically, the hydraulic control pipe 9b of redundant solution in the casing 2 by liquid-level controller 9 is outside vacuum check valve 8 drains into casing 2, liquid level in the casing 2 is effectively controlled, is normally getting ready of next time working.
