Description
Technical Field
The utility model relates to a chemistry experiment facility, specific theory has related to a fume hood for clearing up jar acid dip.
Background
The fume hood is a common large-scale device in a chemical laboratory, mainly reduces harmful gas generated in the experiment, and is a barrier for protecting laboratory personnel and preventing danger of toxic and harmful chemical substances.
In the detection of heavy metal elements, a nitric acid soaking digestion tank, a volumetric flask and various utensils are often needed, and the situation that the nitric acid soaking digestion tank, the volumetric flask and various utensils can not be spilled on a panel inside a fume hood and outside in the soaking process and the waste liquid pouring process or can not be splashed on a laboratory staff is avoided.
At present, the operating platform and the outer ring of the fume hood on the market are made of common plastics, and the fume hood is easy to slowly glue when meeting acid in the daily soaking process, so that the fume hood is damaged, and the fume hood serving as an infrastructure is difficult to replace and high in cost.
In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The utility model aims at the not enough of prior art to a fume hood for clearing up jar acid soaking that acid resistance, long service life, difficult sputter, difficult acid leakage are provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a fume hood for digestion tank acid soaking comprises an operation platform, wherein an invaginated groove is formed in the operation platform, a polytetrafluoroethylene thin plate attached to the groove structure is laid in the invaginated groove, the polytetrafluoroethylene thin plate is of an integral structure, and the periphery of the polytetrafluoroethylene thin plate is matched with the groove to form a water retaining edge; a waste liquid port is further formed in the groove, a pipe orifice is correspondingly formed in the polytetrafluoroethylene thin plate, the pipe orifice penetrates out of the bottom of the waste liquid port, and an external thread connector is arranged at the tail end of the pipe orifice; and a waste liquid barrel is arranged below the waste liquid port, and the top end of the waste liquid barrel is in threaded fit connection with the external thread interface.
And the polytetrafluoroethylene thin plate wraps the water retaining edge and bypasses the water retaining edge for 5-10 cm.
Basically, the polytetrafluoroethylene thin plate and the groove are of a detachable embedded structure.
Basically, the tail end of the pipe orifice is connected with a polytetrafluoroethylene end cover through a guide rope, and the polytetrafluoroethylene end cover is in threaded fit with the external thread interface.
Basically, the ratio of the groove to the area of the operating platform is 80-90%.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses with the form of operation platform design for the recess, and lay the polytetrafluoroethylene sheet metal in the recess, form the manger plate edge all around, design waste liquid mouth in inside, and extend the mouth of pipe structure extension of polytetrafluoroethylene sheet metal through waste liquid mouth, wear out from the bottom of waste liquid mouth, form continuous integrative structure, even if take place the situation of acid leakage like this, also can protect the overall structure of fume hood stable, do not receive the influence of materials such as nitric acid, reduced the possibility of sputter operation platform simultaneously, security and life obtain great extension.
Drawings
Fig. 1 is a schematic structural view of a fume hood for digestion tank acid soaking according to the present invention.
Figure 2 is a sectional view of a fume hood for use in digesting tank acid infusions in accordance with the present invention.
In the figure: 1. an operating platform; 2. a groove; 3. a polytetrafluoroethylene sheet; 4. a water retaining edge; 5. a waste liquid port; 6. a pipe orifice; 7. a waste liquid barrel; 8. a polytetrafluoroethylene end cap.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1 and 2, the fume hood for acid leaching of the digestion tank comprises an operation platform 1, wherein an invaginated groove 2 is formed in the operation platform, the groove accounts for 80-90% of the area of the operation platform, a polytetrafluoroethylene thin plate 3 attached to the groove structure is laid in the invaginated groove 2 to form the invaginated operation platform, the operable part of the platform is made of polytetrafluoroethylene, the acid resistance is high, the polytetrafluoroethylene thin plate and the groove are of detachable embedded structures, and fixing structures such as structural glue or nails are not used so as to facilitate replacement or cleaning of an interlayer at any time.
A waste liquid port 5 is further formed in the groove 2, a pipe orifice 6 is correspondingly formed in the polytetrafluoroethylene thin plate 3, the pipe orifice 6 penetrates out of the bottom of the waste liquid port 5, and an external thread connector is arranged at the tail end of the pipe orifice 6, so that the main body of the fume hood cannot be contacted in the whole flowing process of the cleaned waste water, no gap exists, and the possibility of acid leakage does not exist; waste liquid barrel 7 is installed below waste liquid port 5, the top of waste liquid barrel 7 with external screw thread interface screw-thread fit is connected, a polytetrafluoroethylene end cover 8 is connected through the leader to the tail end of mouth of pipe 6, the polytetrafluoroethylene end cover with external screw thread interface screw-thread fit, during the use, links together waste liquid barrel 7 and the mouth of pipe 6 of waste liquid port 5 department for accept acidic waste liquid, when not using, covers the mouth of pipe with the polytetrafluoroethylene end cover, avoids the acidizing fluid seepage.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
