Description
Technical Field
The utility model relates to a container cover body specifically is a prevent splash backward flow lid.
Background
The monitoring experiment of pollutants such as air, waste gas, fixed pollution sources and the like accounts for a large proportion in environmental monitoring, and is an indispensable monitoring index. When samples such as air, waste gas, fixed pollution sources and the like are collected, a method of intercepting substances to be detected in the gas by using a filter membrane and a filter cylinder is mostly adopted, and then the samples are taken back to a laboratory for detection. All need heat before the detection and clear up the processing, clear up and have the potential safety hazard in the experimentation, the experimenter need pay close attention to the condition of heating in the bottle constantly, but the problem of splash can't be avoided appearing, and the splash not only can cause the harm of scald to the experimenter, still can lead to gathering sample testing result inaccurate. The conventional method for solving the problem is to purchase devices such as a microwave digestion instrument and a digestion tank, but the devices are high in price and high in cost, a plurality of inspection and detection mechanisms consider to save the cost and cannot select to purchase, and the problem of how to avoid the experimental risk needs to be solved urgently.
The prior art CN207288286U discloses a CIP anti-splashing backflow device, which mainly comprises a baffle, a blowout-preventing cap and a guide plate; the baffle is cylindrical and is sleeved on the periphery of a tank cover at the top of the fermentation tank and welded on the tank cover; the blowout prevention cap is arranged above the baffle plate, and the baffle plate is sleeved in the blowout prevention cap; the guide plate is welded on the wall of the tank around the baffle plate, and the inner plate body is welded with a limit nail; the guide plate is close to the lowest position of the horizontal position of the tank side wall and is provided with a guide opening, the guide opening is provided with a drainage tube along the tank side wall, and a collection box is connected below the drainage tube. This method of preventing the liquid inside from being ejected is a common design method by directly modifying the outlet of the container. The above prior art is not suitable for use with small, especially laboratory, heating vessels.
Disclosure of Invention
The utility model discloses a solve uncovered container heating, liquid provides a splashproof backward flow bottle lid from the technical problem of bottleneck splash.
The technical scheme includes that the anti-splash backflow bottle cap comprises a connecting cover bottom, a condensation cavity is arranged on the peripheral wall of the connecting cover bottom, a water inlet and a water outlet are formed in the condensation cavity, a backflow funnel is arranged on the inner wall of the connecting cover bottom, a cover top is arranged on the upper portion of the connecting cover bottom, an air outlet is formed in the position of the upper side face of the backflow funnel, the backflow funnel comprises an upper funnel on the upper portion and a lower funnel on the lower portion, and small end portions of the upper funnel and the lower funnel are connected and communicated.
When using, at first add the pending sample, will link up the lid end and look into the bottleneck and be connected with the bottle well, condensation function alternative use, water inlet and delivery port are connected well during the use, heat again and clear up, if not take place the splash, steam can be followed two gas outlets and discharged among the heating process, if take place the splash, the liquid of splash to the caping, can stay to the return-flow funnel in along the guide plate, finally flow back to the container in, the liquid of splash to lid body lateral wall then accessible return-flow funnel flows back to the container immediately rapidly, reach and prevent spun effect.
Particularly, the backflow funnel is internally and symmetrically connected by an upper funnel and a lower funnel, the upper funnel can enable liquid splashed to the top to flow back, and the lower funnel can prevent a part of liquid splashed to the middle from rushing out.
The condensation chamber is positioned at the inner side of the connecting cover bottom, and the space formed between the reflux funnel and the connecting cover bottom is the condensation chamber.
The condensation chamber is adjacent to the return funnel, and can directly cool the gas rushing through the return funnel gap, thereby preventing a large amount of steam from leaking, having good cooling effect and reducing the pressure of splashing.
The condensation cavity is an annular cavity, the water inlet is positioned at the lower part of the condensation cavity, and the water outlet is positioned at the upper part of the condensation cavity. The heat absorption can be carried out in the largest area, and the cooling effect of the bottle mouth is improved.
The cover top is spherical, a guide plate is arranged below the cover top and is positioned on the air outlet side, the guide plate is inclined, and the lower end of the guide plate is positioned above the reflux funnel.
After the gas or liquid drops directly impact the lower part of the cover top, the liquid drops to the reflux funnel through the guide plate, and the liquid is prevented from being sprayed out from the gas outlet on the side along with the steam.
Compared with the prior art, the utility model discloses avoid liquid splash to outside scald experimenter, protected experimenter safety, avoided simultaneously clearing up the sample and leaded to the problem that the testing result has the deviation because of the splash loss, improved the rate of recovery of clearing up the sample. The cost is low, and various digestion systems with high value are not needed to be purchased, so that the cost of a digestion experiment is reduced; meanwhile, the bottle cap is simple to operate, convenient to use and wide in application.
