Abstract
The utility model provides a rapid filtering funnel for a chemical experiment. The rapid filtering funnel comprises a funnel barrel body and a funnel pipe, wherein a spiral heave is spirally arranged on the inner wall of the funnel barrel body, and a reinforced holding handle is connected onto the outer side wall of the top edge of the funnel barrel body. Compared with the prior art, the rapid filtering funnel for the chemical experiment has the advantages of reasonable design, simple structure, convenience in use and the like, is high in liquid flowing speed and ideal in filtering effect, improves the efficiency of the chemical experiment, and is low in cost and easy to manufacture, thus having good population and using values.
Description
Technical field
The utility model relates to a kind of experimental article, specifically a kind of simple in structure, chemical experiment rapid filtering funnel.
Background technology
Funnel is one of requisite laboratory apparatus in the chemical laboratory, and funnel is a cartridge type object, is used as liquid and powdery object are injected the more tiny container of entrance.The tubulose more tiny at the funnel mouth partly can have different length.When filtering in the chemical laboratory of prior art, earlier filter paper is rolled into taper shape and puts into funnel and water adhesional wetting, make filter paper be close to the funnel inwall, then filtrate is poured into, filtrate penetrates filter paper and realizes filtering.But this filter type is slower, and the filtrate flows process is slow especially.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, chemical experiment rapid filtering funnel is provided.
The technical solution of the utility model realizes in the following manner, this a kind of chemical experiment rapid filtering funnel, comprise funnel cylindrical shell, filler tube, spiraling on the inwall of described funnel cylindrical shell is provided with spiral salient, is connected with the reinforcing grab handle on the top of funnel cylindrical shell along lateral wall.When adopting technique scheme to carry out chemical experiment, at first filter paper is filled in the funnel cylindrical shell along spiral salient, then filter paper is bedewed, pour liquid into funnel along spiral salient, because the spiral prominence role, prolonged the filtration time of liquid, can guarantee that filtrate carries out fast simultaneously.
As preferably, described reinforcing grab handle is made up of the connection handle that is inverted "L" shaped and horizontal hand holding handle.The setting of connection handle is for auxiliary the funnel cylindrical shell to be fixed, and hand holding handle is convenient this funnel cylindrical shell that grips then.
The beneficial effect that the utility model compared with prior art produces is:
A kind of chemical experiment of the present utility model with rapid filtering funnel have simple in structure, easy to use, characteristics such as be skillfully constructed, liquid flow velocity is fast, the filter effect ideal, improved the efficient of chemical experiment, and the funnel that the utility model provides is with low cost, be easy to make, thereby have good value for applications.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, funnel cylindrical shell, 2, spiral salient, 3, connection handle, 4, hand holding handle, 5, filler tube.
The specific embodiment
Below in conjunction with accompanying drawing a kind of chemical experiment of the present utility model is done following detailed description the in detail with rapid filtering funnel.
As shown in Figure 1, this a kind of chemical experiment rapid filtering funnel comprises funnel cylindrical shell 1, filler tube 5, and spiraling on the inwall of described funnel cylindrical shell 1 is provided with spiral salient 2, is connected with the reinforcing grab handle on the top of funnel cylindrical shell 1 along lateral wall.
Described reinforcing grab handle is made up of the connection handle 3 that is inverted "L" shaped and horizontal hand holding handle 4.
In the above-described embodiments, preferred forms of the present utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations, become other shapes such as " Z " shape such as the alteration of form that will reinforce grab handle, in essential scope of the present utility model, also can make a lot of variations, remodeling, interpolation or replacement.At this, should illustrate that any change of making all will fall in the protection domain of the present utility model under inventive concept of the present utility model.
