Description

A kind of novel concentration purifying plant

Technical field

The utility model relates to chemical experiment device technical fields.Specifically a kind of novel concentration purifying plant.

Background technique

Concentration purification is a kind of common product or feedstock purification means in laboratory, such as the purification of cupric sulfate pentahydrate, In order to accelerate experiment progress, it will usually accelerate to be separated by solid-liquid separation by the way of filtering, and existing Suction filtration device, it is leaked to suction filtration When bucket is cleaned, generally requires first to remove suction funnel from bottle,suction on the whole and then clean.To some strength For insufficient experimenter, suction funnel is removed to some difficulty from bottle,suction, often will appear bottle,suction translate into or Person's other accidents.And existing suction funnel existed in the concentration purification experiment for retaining filtrate filtrate introduce it is new miscellaneous The possibility of matter has been easy residual that is, since the cavity below suction funnel orifice plate is not easy to be cleaned completely, easily is needed to retain The experiment of filtrate brings new problem.

Utility model content

For this purpose, the technical problem to be solved by the utility model is to provide a kind of novel concentrations convenient for operation to purify dress It sets, the safety in utilization of concentration purification operations whole flow process is improved using split type suction funnel, while being also convenient for strength not The people of foot single can carry out concentration purification using Suction filtration device.

In order to solve the above technical problems, the utility model provides the following technical solutions:

A kind of novel concentration purifying plant, which is characterized in that including vacuum pump, bottle,suction, safety flack and suction funnel；Institute The lower end for stating suction funnel passes through rubber plug and is arranged in the suction filtration bottleneck, the outlet side for filtering bottleneck and the safety flack Inlet end fluid communication connection, the outlet side of the safety flack is connect with the inlet end fluid communication of the vacuum pump；It is described The blow-down pipe of bottle,suction is sealed by fixture；The suction funnel, including drainage tube, taper collecting pipe, solution hold pipe, orifice plate And casing；The upper end of the drainage tube is fixedly connected with the necking end of the taper collecting pipe, the flaring of the taper collecting pipe End is fixedly connected with the lower end of described sleeve pipe, and described sleeve pipe, which is covered, to be held on pipe in the solution and hold the seal of tube with the solution Connection；The orifice plate setting, which holds in pipe in the solution and holds pipe with the solution, to be fixedly connected, and the orifice plate is located at institute State the top that solution holds the outlet end of pipe.

Above-mentioned novel concentration purifying plant, described sleeve pipe and the solution, which are held, is equipped with sealant between pipe.

Above-mentioned novel concentration purifying plant, the sealant are petrolatum layer.

Above-mentioned novel concentration purifying plant is equipped with gap between the sealant and taper confluence inside pipe wall.

The technical solution of the utility model achieves following beneficial technical effect:

1. reduce suction funnel using split type suction funnel removes the difficulty cleaned from bottle,suction, meet The single demand that concentration purification is carried out using Suction filtration device of strength lesser people is reduced during concentration purification operations because tearing open The experiment accident washing suction funnel and occurring.

2. split type suction funnel is conducive to clean the cavity below suction funnel hollow plate, reduce the cavity Pollution of the interior residuals to filtrate.

Detailed description of the invention

Fig. 1 is that the novel concentration of the utility model proposes the structural schematic diagram of device；

Enlarged drawing at A in Fig. 2 Fig. 1.

Appended drawing reference indicates in figure are as follows: 10- suction funnel, 11- solution hold pipe, 12- drainage tube, 13- taper collecting pipe, 14- casing, 15- orifice plate, 16- sealant；20- bottle,suction；30- safety flack；40- vacuum pump；50- blow-down pipe；60- fixture；70- Rubber plug.

Specific embodiment

As depicted in figs. 1 and 2, the novel concentration purifying plant of the utility model, which is characterized in that including vacuum pump 40, Bottle,suction 20, safety flack 30 and suction funnel 10；The lower end of the suction funnel 10 passes through rubber plug 70 and is arranged in the bottle,suction In 20 mouthfuls, the outlet side of 20 mouthfuls of the bottle,suction is connect with the inlet end fluid communication of the safety flack 30, the safety flack 30 Outlet side connect with the inlet end fluid communication of the vacuum pump 40；The blow-down pipe 50 of the bottle,suction 20 is close by fixture 60 Envelope；The suction funnel 10, including drainage tube 12, taper collecting pipe 13, solution hold pipe 11, orifice plate 15 and casing 14；It is described The upper end of drainage tube 12 is fixedly connected with the necking end of the taper collecting pipe 13, the flared end of the taper collecting pipe 13 and institute The lower end for stating casing 14 is fixedly connected, and 14 sets of described sleeve pipe is held on pipe 11 in the solution and to hold pipe 11 with the solution close Envelope connection；The setting of orifice plate 15, which holds in pipe 11 in the solution and holds pipe 11 with the solution, to be fixedly connected, the hole Plate 15 is located at the top that the solution holds the outlet end of pipe 11.When carrying out simple concentration purification, such as cupric sulfate pentahydrate Concentration purification, holds pipe 11 for the solution and is placed in described sleeve pipe 14, then put filter paper, Ji Kekai on the orifice plate 15 The vacuum pump 40 is moved filter.

Some colloids can be generated by being concentrated in purification process in view of some substances, or the crystal grain generated is comparatively fine, so that Gap between crystal grain is smaller, is unfavorable for passing through for liquid, in order to improve the draught head between the bottle,suction 20 and the external world, removes Except the efficiency of the raising vacuum pump 40, it can also be held between pipe 11 by improving described sleeve pipe 14 and the solution Air-tightness, for this purpose, held in described sleeve pipe 14 and the solution in the present embodiment and be equipped with sealant 16 between pipe 11, it is described close Sealing 16 is petrolatum layer.And the vaseline during filtering in order to avoid long-time in the petrolatum layer can be acted in pressure In lower trickling to 13 inner wall of taper collecting pipe being located at immediately below the orifice plate 15, in the present embodiment, in the sealant Gap is equipped between 16 and 13 inner wall of taper collecting pipe.

When using the utility model, when needing to clean suction funnel 10, it is thus only necessary to hold the solution Pipe 11 takes out from described sleeve pipe 14 and is cleaned, without taking the entire suction funnel 10 from the bottle,suction 20 Get off, consequently facilitating the insufficient people of strength carries out concentration purification operations by way of suction filtration, improves concentration purification experiment Operational safety.

The state that the petrolatum layer and the taper confluence inside pipe wall contact is shown in the present embodiment, in Fig. 2, it can be with Meet the suction filtration requirement in general concentration purification experiment, but when carrying out filtering operation for a long time, the sealant should be made There are gaps between 16 and 13 inner wall of taper collecting pipe.

Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes among still in present patent application scope of protection of the claims.
