Abstract
The utility model provides a solid-state powder shifts funnel. A straight-through sleeve pipe is sleeved on the outer side of the lower part of the conical upper guide pipe to replace a circular lower guide pipe, and a clamping groove is formed in the outer surface of the conical upper guide pipe matched with the straight-through sleeve pipe; the diameter phi D of the straight-through sleeve is larger than the diameter phi D of the lower part of the conical upper conduit. The utility model adopts the straight-through sleeve to replace the round lower conduit, and the non-round lower conduit is more convenient for solid powder to slide down and fall down, so that the solid powder can be transferred into a utensil with smaller diameter of the bottleneck more smoothly without residue and loss; the straight-through sleeve at the lower part of the conical upper guide pipe can also play a role in fixing the conical funnel, the straight-through sleeve and the clamping groove of the conical upper guide pipe have a role in further fixing the conical funnel, the operation is simple, the reusability is high, and the working efficiency is improved. The powder transfer funnel is suitable for being used as a solid powder transfer funnel.
Description
Technical Field
The utility model relates to a conical hopper in the field of chemical experiments, in particular to a lower conduit section of a conical hopper.
Background
At present, more solid powdered medicines or samples are transferred to conical bottles or test tube vessels with smaller bottle mouth diameters in laboratories. Because test tube erlenmeyer flask bottleneck diameter is less, it is great to shift the degree of difficulty, and conventional funnel can not be fine satisfy the needs of shifting and cause the residue of solid powdered medicine or sample easily, influences the experimental result accuracy.
Disclosure of Invention
In order to solve the accurate transfer of solid-state powder, avoid remaining on the household utensils, improve the accuracy of experimental result, the utility model provides a solid-state powder shifts funnel. This funnel has increased the diameter of toper funnel lower part discharge gate through the round downcomer of direct pipe replacement, and the gliding of the solid powder of being convenient for falls and shifts fast, and solid powder medicine or sample do not have on the household utensils and remain when solving solid powder and shifting technical problem.
The utility model provides a scheme that technical problem adopted is:
a straight-through sleeve pipe is sleeved on the outer side of the lower part of the conical upper guide pipe to replace a circular lower guide pipe, and a clamping groove is formed in the outer surface of the conical upper guide pipe matched with the straight-through sleeve pipe;
preferably, the diameter phiD of the straight-through sleeve is larger than the diameter phid of the lower part of the conical upper guide pipe;
preferably, the diameter phid of the lower part of the conical upper guide pipe is larger than the diameter phid of the lower part of the conical upper guide pipe of the conventional conical funnelo。
The utility model has the advantages that as the straight-through sleeve pipe is adopted to replace the circular lower conduit, the non-circular lower conduit is more convenient for solid powder to slide down and fall down, so that the solid powder can be transferred into a vessel with smaller diameter of the bottleneck more smoothly without residue and loss; the straight-through sleeve at the lower part of the conical upper guide pipe can also play a role in fixing the conical funnel, the straight-through sleeve and the clamping groove of the conical upper guide pipe have a role in further fixing the conical funnel, the operation is simple, the reusability is high, and the working efficiency is improved. The powder transfer funnel is suitable for being used as a solid powder transfer funnel.

Fig. 2 is a schematic view of the present invention.
In the figure, 1 is a conical upper duct, 2 is a circular lower duct, 3 is a straight-through sleeve, phid is the diameter of the lower part of the conical upper duct, phid is the diameter of the straight-through duct, phidoDiameter of lower part of upper conduit of conventional cone funnel cone type.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is to be understood that although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
As shown in the figure, a straight-through sleeve 3 is sleeved on the outer side of the lower part of a conical upper guide pipe 1 to replace a circular lower guide pipe 2, and a clamping groove is arranged on the outer surface of the conical upper guide pipe matched with the straight-through sleeve.
The diameter phi D of the straight-through sleeve is larger than the diameter phi D of the lower part of the conical upper conduit.
The diameter phi d of the lower part of the conical upper conduit is larger than the diameter phi d of the lower part of the conical upper conduit of the conventional conical funnelo。
The utility model discloses a theory of operation:
ordinary conical hopper is equipped with tapered upper pipe and circular downcomer, and tapered upper pipe bottom diameter is the diameter of circular downcomer promptly, and during solid-state powder shifts, because the upper portion diameter of tapered upper pipe and the lower part diameter of tapered upper pipe differ greatly, solid-state powder gliding falls and easily remains in the internal surface of household utensils, influences the accuracy of experiment.
The straight-through sleeve pipe is adopted to replace the circular lower guide pipe, the diameter of the lower part of the conical upper guide pipe is correspondingly increased, so that the difference between the diameter of the upper part of the conical upper guide pipe and the diameter of the lower part of the conical upper guide pipe is reduced, solid powder rapidly slides down and falls when being transferred, no residue is left on the inner surface of a vessel, and the accuracy of an experiment is improved; the outer surface of the conical upper catheter is provided with a clamping groove which forms stable matching with the straight-through sleeve.
The utility model has the characteristics that:
the straight-through sleeve pipe is adopted to replace the circular lower conduit, so that the non-circular lower conduit is more convenient for solid powder to slide down and fall, and is smooth and free of residues; the straight-through sleeve at the lower part of the conical upper guide pipe can also play a role in fixing the conical funnel, and the straight-through sleeve and the clamping groove of the conical upper guide pipe have a role in further fixing the conical funnel. According to different application modes, the size of the conical funnel formed by the conical upper guide pipe and the straight-through sleeve pipe can be adjusted, and the application requirements are met.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
