Abstract
A fume cupboard top cover with a liquid receiving function comprises a wall plate. The wall plate is provided with a vent hole, a liquid collecting face is formed on the periphery of the vent hole and is inclined downwards gradually from inside to outside, the edge of the bottom end of the liquid collecting face is bent from outside to inside to form a liquid receiving groove, and the liquid receiving groove is connected with a flow guiding pipe. Compared with the prior art, the fume cupboard top cover can prevent harmful liquid from flowing into a main box of a fume cupboard, protects a fume cupboard main body and internal devices from damage, and prolongs service life of the fume cupboard. Simultaneously, the harmful liquid is recycled in a concentrated mode, back flow of the harmful liquid is avoided, smooth running of tests is guaranteed, and test operation safety is improved.
Description
Technical field
The utility model relates to ventilation hoods for laboratories, is specifically related to the vent cabinet overhead guard that a kind of band connects the liquid function.
Background technology
Present stage, in carrying out the scientific research and testing process, the vent cabinet equipment that is absolutely necessary.Yet existing vent cabinet can not satisfy the requirement of scientific research and testing, for example, when the scientific research personnel does the acid mist test in vent cabinet, the overhead guard of vent cabinet will residual acidity liquid, the more liquid of overhead guard accumulation will be dropped in the vent cabinet, so not only can influence accuracy of experimental results, also might damage the instrument in the vent cabinet simultaneously, simultaneously, acid liquid can corrode the cabinet of vent cabinet, shortens the service life of vent cabinet.
The utility model content
At the deficiencies in the prior art, the vent cabinet overhead guard that provides a kind of band to connect the liquid function is provided the purpose of this utility model, and it can improve the service life of vent cabinet, increases the accuracy of test.
For achieving the above object, the utility model adopts following technical scheme:
Band connects the vent cabinet overhead guard of liquid function, comprises wallboard, offers an air vent on the wallboard, the periphery of air vent forms a liquid collecting face, gradually downward-sloping from inside to outside of this liquid collecting face, edge, the bottom ecto-entad of liquid collecting face is bent to form and connects liquid bath, connects and is connected with a mozzle on the liquid bath.
Connect liquid bath closed form ringwise.
Connect on the diapire of liquid bath and offer a pod apertures, a water conservancy diversion mouth is installed on this pod apertures, mozzle turns on the water conservancy diversion mouth.
The beneficial effects of the utility model are:
Than prior art, the utility model can prevent that harmful liquid from flowing in the main box of vent cabinet, and protection vent cabinet main body and internal unit are without prejudice, and have improved the service life of vent cabinet.Simultaneously, harmful liquid is concentrated and is reclaimed, and prevents that harmful liquid from flowing backwards, and has guaranteed carrying out smoothly of test, has improved the security of test operation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Wherein: 1, wallboard; 2, liquid collecting face; 3, connect liquid bath; 4, air vent; 5, mozzle; 6, pod apertures; 7, water conservancy diversion mouth.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Referring to Fig. 1,2, vent cabinet overhead guard of the present utility model comprises the wallboard 1 as the overhead guard main part, its material is fiberglass, offer an air vent 4 at wallboard 1, the periphery of air vent 4 forms a liquid collecting face 2, this liquid collecting face 2 gradually downward-sloping from inside to outside, namely downward-sloping by the edge of air vent 4, the edge, bottom of liquid collecting face 2 has one and connects liquid bath 3, connecing liquid bath 3 is the grooves that formed by the edge ecto-entad bending of liquid collecting face 2 bottom, connect and be connected with a mozzle 5 on the liquid bath 3, this mozzle 5 is used for will connecing the liquid guide flow of liquid bath 3 to assigned address.
Above-mentioned liquid collecting face 2 can be by four the downward-sloping inclined-planes of difference all around that are positioned at air vent 4, two adjacent inclined-plane wiring place bendings, liquid collecting face 2 also can be to be round table-like, in a word, no matter liquid collecting face 2 adopts above-mentioned the sort of structure, and the liquid bath 3 that connects of its bottom all is closed annulars.Connect on the diapire of liquid bath 3 and offer a pod apertures 6, a water conservancy diversion mouth 7 is installed on the pod apertures 6, above-mentioned mozzle 5 is installed on the water conservancy diversion mouth 7.
The harmful fog that produces in the process of the test touches the inwall of liquid collecting face 2 or air vent 4 when rising, meet condensation and form droplet, and these droplets flow into along liquid collecting face 2 and connect in the liquid bath 3, flow to assigned address through mozzle 5 again and are collected.Through collecting, can prevent that harmful liquid from flowing in the main box of vent cabinet, protection vent cabinet main body and internal unit are without prejudice, and have improved the service life of vent cabinet.Simultaneously, harmful liquid is concentrated and is reclaimed, and prevents that harmful liquid from flowing backwards, and has guaranteed carrying out smoothly of test, has improved the security of test operation.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
