Abstract
The utility model relates to a pressure-reducing filter, which is characterized by consisting of a sealing cover and a barrel, wherein the sealing cover is sealed with an opening of the barrel, the middle part of the sealing cover is provided with a hole which is connected with a Buchner funnel by a rubber plug, and the side face of the barrel is provided with an air suction a branch nozzle which is connected with a conduit for a vacuum pump. The utility model has the advantages that the filter does not need to be cleaned repeatedly, filtrate does not need to be transferred after filtration, the volume of the filtrate is not increased, the concentration is not reduced, water is saved, and a volumetric flask, a beaker, a reagent bottle or other containers can all be directly used as a filtrate collecting container. The pressure-reducing filter breaks through the limit that the filtrate can only be collected by an absorption flask, and is more ideal for the situation requiring high accuracy and small filtering volume in scientific researches, experiments and the like.
Description
Technical field:
The utility model relates to the filtration under diminished pressure in the chemical experiment, belongs to the experimental technique field, is specifically related to vacuum filter.
Background technology:
Filtration is the common method of separating solids and liquid in the chemical experiment, filtration is divided into normal pressure and filters and filtration under diminished pressure, the two relatively, filtration under diminished pressure has the under equal conditions fast characteristics of separating rate, and filtration under diminished pressure can can't filter or normal pressure filters consuming time oversize etc. in particular cases use at the big normal pressure of viscosity.
The used instrument of filtration under diminished pressure has cloth formula funnel, bottle,suction and vavuum pump, utilizes the effect of finding time of vavuum pump, constantly the air in the bottle,suction is taken away, and it is poor with the outer build-up of pressure of liquid level to make in the cloth formula funnel, and reaches the purpose of filtration.
In conventional filtration under diminished pressure operating process, filtrate is filtered to earlier in the bottle,suction, after operation to be filtered is finished, the filtrate in the bottle,suction is transferred in other container.In order to obtain purer filtrate and to reduce filter loss, need repeatedly to clean bottle,suction before the experiment, when carrying out scientific research, require in the accurate result, to wash bottle,suction with water 2 to 3 times after having shifted filtrate, with washing lotion and filtrate merging, get final filtered fluid.More than there is following problem in operation:
1. the washing bottle,suction shifts filtrate, and operating procedure is more, and the time is long;
2. filtering rear filtrate needs to shift, and filtrate is easily lost, complicated operation;
3 washing lotions and filtrate merge, and filtrate volume is increased, and concentration reduces, and increases post-processing difficulty;
4. want water when washing bottle,suctions many times, the waste experimental water;
4. carry out the amount of filtration under diminished pressure when smaller at needs, not easy to operate.
Summary of the invention:
The utility model provides a kind of new vacuum filter at above-mentioned deficiency, to replace bottle,suction.The container that the utility model vacuum filter directly will receive filtrate is put in the bucket of vacuum filter, allows it directly receive the filtrate that cloth formula funnel leaches, and is used with cloth formula funnel and vavuum pump, reaches the purpose of filtration under diminished pressure.
It is characterized in that: the utility model vacuum filter is made up of seal cover and bucket, and seal cover can seal with the opening of bucket, and is porose in the middle of the seal cover, is connected with plug with cloth formula funnel or other funnel, and the side of bucket is provided with a mouth of bleeding, and is connected with conduit with vavuum pump.
The advantage of the utility model vacuum filter is to have removed steps such as cleaning repeatedly, has simplified operation, has saved the time; After the filtration, need not shift filtrate, filtrate volume does not increase, and concentration does not reduce, and is convenient to the back experiment; Need not clean the conserve water resource in the operation repeatedly; The container that receives filtrate is put in the bucket of vacuum filter, breaks the restriction that can only be received filtrate by bottle,suction, the filtrate receiving vessel can directly use volumetric flask, beaker, examination Ji bottle or other container.

1 seal cover
2 barrels
3 seal cover interstitial holes
A mouth of bleeding of 4 barrels of sides
5 cloth formula funnels
6 connect the plug of cloth formula funnel and seal cover
7 receive the beaker that filtrate is used
The specific embodiment
The utility model decompression transition and cloth formula funnel and vavuum pump are finished the operation of filtration under diminished pressure jointly.
1 is connected the degree of tightness appropriateness with cloth formula funnel with plug with seal cover;
2 usefulness sebific ducts are connected the vavuum pump bleeding point with a mouth of bleeding of bucket;
3 with the container that will receive filtrate put into the bucket the centre position;
4 seal covers that will be connected with cloth formula funnel cover on bucket;
5 open vavuum pump, add filter paper, add material to be filtered and get final product suction filtration;
After 6 suction filtrations are finished, close vavuum pump, treat to open the seal cover that is connected with cloth formula funnel after pressure reduces, take out receiving vessel, suction filtration is finished.Illustrate: the used funnel of 1 the utility model decompression transition is not can only be cloth formula funnel, so long as can the usefulness plug be connected with seal cover all can, as sand core funnel.
Be used to receive the container of filtrate in 2 barrels, can use so long as can put into any container of bucket, as reagent bottle, beaker, volumetric flask, test tube etc.
