Abstract
The utility model relates to the technical field of auxiliary equipment in a conventional chemical laboratory, in particular to a novel laboratory waste liquid collecting barrel. The waste liquid collecting barrel comprises a barrel body, a one-way valve type device, a barrel cover and a limiting groove. The barrel cover and the barrel body are screwed together through threads; one-way valve formula device is fixed in spacing groove department, can dismantle simultaneously, two emulsion sheet films of one-way valve formula device are because atmospheric pressure and liquid surface tension's reason are laminated closely each other, can effectively prevent gaseous volatilizing and the spill of liquid, reduce the diffusion of the pungent smell that brings when the waste liquid stirs, the environment of collecting of a waste liquid that gives the experimenter better relatively.
Description
Technical Field
The utility model relates to the technical field of auxiliary equipment in a conventional chemical laboratory, in particular to a novel laboratory waste liquid collecting barrel.
Background
For a long time, in chemical experiments, a large amount of waste liquid is often generated, and the waste liquid contains many volatile and toxic substances, such as methanol, acetonitrile, isopropanol, n-hexane, tetrahydrofuran, trifluoroacetic acid, ethyl acetate, acetone, phenol and the like. The waste liquid is usually contained in a plastic barrel with a large capacity, the waste liquid contained in the waste liquid is directly contacted with the outside air, no protective measures are provided, the smell of the waste liquid is pungent, and experimenters need to bear the pungent smell brought by the waste liquid when collecting the waste liquid, so that the experimenters are greatly harmed; and the pollution to the surrounding experimental environment can be caused.
Therefore, there is a need in the chemical laboratory to provide a collection bucket that reduces the harsh odors associated with collecting waste fluids.
Disclosure of Invention
In order to solve the problems, the utility model designs a novel laboratory waste liquid collecting barrel to solve the problems that a laboratory provided in the background art generates more volatile pungent waste liquid, the waste liquid contained in the laboratory directly contacts with the outside air, no protective measures are provided, and the like, and the harm to a human body or the pollution to an experimental environment are avoided.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a novel laboratory waste liquid collecting vessel, includes the staving that the resistant strong corrosion material was made, the top of staving is equipped with detachable and is used for empting one-way flap formula device and the spacing groove of waste liquid, and one-way flap formula device is placed in the bellied spacing groove department of staving, and the bung passes through the screw thread with the staving and is in the same place soon.
One-way valve formula device be a hollow section of thick bamboo, the upper end bending of a section of thick bamboo just is fixed in the sealed pad of staving spacing groove, be provided with film formula check valve in the section of thick bamboo, film formula check valve is two films including the symmetry setting, two films are the latex film, the material of a section of thick bamboo is polyvinyl chloride, two films all include the upper segment and the vertical hypomere of slope, the upper segment of two films and rather than the contained angle of the hypomere that corresponds are 140~160, the edge of two film upper segments all with the inner wall in close contact with and fixed connection of a section of thick bamboo, two film hypomere laminate each other and form liquid outlet channel.
The utility model has the beneficial effects that:
by adding the one-way valve type device, the two emulsion sheet films are tightly attached to each other due to the air pressure and the surface tension of the liquid, so that the volatilization of air and the splashing of the liquid can be effectively prevented, the diffusion of pungent smell caused by the turning of the waste liquid is reduced, and a relatively good waste liquid collection environment is provided for experimenters.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a one-way valve device according to the present invention
In the figure: 1. a barrel body; 2. a one-way flapper type device; 3. a barrel cover; 4. a limiting groove.
Detailed Description
The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples, which are provided to illustrate the present invention and not to limit the scope of the present invention.
The laboratory waste liquid collecting barrel comprises a barrel body 1, a one-way valve type device 2, a barrel cover 3 and a limiting groove 4. The barrel body 1 is a collecting barrel made of strong corrosion resistant materials. The one-way valve type device 2 is fixed at a limiting groove 4 at the upper end inside the barrel body through a sealing ring, the one-way valve type device 2 can be detached and freely installed, the barrel material of the one-way valve type device is all PVC (polyvinyl chloride) or other hard materials, the one-way valve type device is used for resisting pressure and keeping the stable state of the whole collected waste liquid, the deformation of the device caused by external pressure is avoided, a film made of latex material can deform when being subjected to external force and can keep the original state when not being subjected to the external force, and therefore the design of the film realizes the one-way function and effectively prevents the volatilization of gas and the splashing of liquid; the barrel cover 3 and the barrel body 1 are tightly screwed together through threads.
When collecting the waste liquid, unscrew bung 3, done the experiment when the experimenter, pour into the upper end of staving 1 with a large amount of waste liquids, the waste liquid passes through one-way flap formula device 2 fast, has effectively prevented gaseous volatilizing and the spill of liquid, collects the completion back, screws up bung 3 in the upper end of staving 1. The body of the experimenter and the surrounding experimental environment are protected.
The above-mentioned embodiments are merely descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
