Abstract
The utility model discloses a laboratorial leaching device with convenient operation. The device is characterized in that a cylindrical inner container is mounted in a Buchner funnel, and a sealing ring is also arranged in the inner container and matched with the ring-shaped bottom of the inner container; an exhaust pipe provided with a cock is inserted in a rubber plug; another cock is mounted at the front segment of a negative-pressure rubber tube; a suck-back prevention isolator is serially connected to a pipeline at the rear part of the negative-pressure rubber tube; and the inlet and the outlet of the negative-pressure rubber tube are mounted on the outer walls of casings at the upper and the lower sections of the suck-back prevention isolator respectively. The laboratorial leaching device has the benefits that the inner container is arranged movably, so that great convenience is provided for removal of filter paper, not only can the filter paper be prevented from being broken, but also leached objects can be prevented from losing advantageously, and even a filter cake can be weighed indirectly; and since the suck-back prevention isolator is arranged, the structure of the device is more compact, and the occupied area is decreased correspondingly.
Description
Technical field
The utility model relates to a kind of laboratory suction filtration device of being convenient to operate.
Background technology
Suction filtration (Leaching) is to utilize aspiration pump that the pressure in the bottle,suction is reduced, thereby realizes the unit operations of the purpose of Separation of Solid and Liquid.In many chemistry and Bioexperiment, all often need obtain product through the mode of suction filtration.Suction filtration device commonly used at present comprises bottle,suction, filter paper and Buchner funnel, during operation filter paper is layered in the Buchner funnel, and the appearance liquid that will filter is placed in the Buchner funnel, through negative pressure system filtrating is collected in the bottle,suction.Adopting this device to exist following deficiency, at first is that filter paper can be bonded on the Buchner funnel tightly, leaches in the process of thing in collection after suction filtration finishes, and filter paper usually can occur and damage, or leach phenomenons such as thing spills, and has influenced test effect.In addition, in order to prevent in the vacuum lines system to occur filtrating suck-back phenomenon, the existing suction filtration device conical flask of also will connecting, the shortcoming of setting is that utensil is comparatively loaded down with trivial details like this, it is also bigger to occupy the space.
Summary of the invention
What the utility model at first will solve is the problem that operation back filter paper is removed difficulty, and it is loaded down with trivial details also will to solve Experimental Establishment in addition, and big problem takes up room.
The technical scheme of the utility model is: this device comprises bottle,suction, Buchner funnel, the red paper of filter and negative pressure pipe, and the plug that the discharging tube of Buchner funnel bottom passes on the bottle,suction bottleneck gets into bottle,suction.An inner bag is housed in Buchner funnel, and this inner bag is cylindric, the inwall interference fit of its outer wall Buchner funnel, and height is a little more than the filter chamber of Buchner funnel, and its bottom has the annular end, in this inner bag, also is provided with a sealing ring that is complementary with its annular end.
The elastic ring that described sealing ring can be processed for elastomeric material also can be processed by glass material, and the sealing ring bottom of adopting glass material to process has frosting, and the upper surface at the inner bag annular end also has frosting.
On this plug, also be inserted with a blast pipe, cock is equipped with in the upper end of blast pipe.Negative pressure sebific duct leading portion being connected with the exhaust tube interface of bottle,suction also is equipped with a cock, anti-suck isolator of series connection on the pipeline of its back.The anti-suck isolator is the closed container of a vertical setting, and the import of negative pressure sebific duct is installed in respectively on upper and lower section the housing outer wall of anti-suck isolator with outlet.
The beneficial effect of the utility model is: owing to increased the inner bag of movable setting,, can avoid filter paper damaged, also help preventing to leach the loss of thing for the removal of filter paper provides very big convenience, even the weight of weighing filter cake indirectly.Owing to be provided with the anti-suck isolator, make the structure of this device compact more, take up room and also dwindle accordingly.
