Description

[Detailed explanation of the invention] (Industrial application field) This invention is used to mix the organic synthesis reaction liquid with a stirrer tip when conducting an organic synthesis reaction of chemical substances. This relates to a chip remover that removes stirrer chips in a funnel when transferring the chips to a container.

(Prior Art) Generally, when two or more chemical substances are mixed and an organic synthesis reaction is carried out, a stirrer chip is placed in the organic synthesis reaction solution and stirred in order to enhance the reaction effect. That is, as shown in FIG.
By rotating the magnet 24 with the motor 25 on the outside of the bottom surface of the container 23, the stirrer chips 21 are moved and stirred by mutual magnetic action. When transferring the organic synthesis reaction solution to another container after stirring, the remaining stirrer chips 21 must be removed.

Therefore, as shown in FIG.
A take-out rod 27 with a magnet 26 attached to the tip was inserted into the container and the stirrer chip 21 was attracted and pulled up.

(Problem to be solved by the invention) However, the stirrer chip 21 and the extraction rod 27
When the magnetic force of the partner is weak or when the weight of the stirrer chip 21 is heavy, the organic synthesis reaction liquid is sometimes transferred to another container with the stirrer chip 21 still in the container because it takes time and effort to take it out.
In addition, if a funnel is used, it is possible to prevent the stirrer chips from being put into another container as is, but as shown in Figure 7, the stirrer chips 21 become stuck at the outlet of the funnel 27, severely restricting the flow of the liquid. It had some flaws that made it worse.

Therefore, in order to eliminate the above drawbacks, this idea
To provide a chip remover which arranges a member for removing stirrer chips in a funnel, improves the flow of liquid, and eliminates stagnation of liquid in the funnel until the end.

(Means for solving the problem) In order to achieve this object, the chip remover according to this invention has at least three sharp protrusions in contact with the inner wall of the funnel, and has a hole of a size that does not allow chips to pass through. The present invention is provided with a chip removing member having a shape and a regulating rod which is erected at the center of the chip removing member and inserted into the discharge pipe of the funnel to restrict the swinging of the chip removing member.

(Example) An example of this invention will be described in more detail below based on the drawings.

FIG. 1 is a partial sectional view showing how the chip remover is used, and FIG. 2 is a longitudinal sectional view thereof. Reference numeral 1 is a chip remover, and 2 is a funnel. The chip remover 1 is composed of a chip removing member 3 and a regulating rod 4. The chip removing member 3 is made of a solvent-resistant and heat-resistant material such as fluororesin, polyethylene, and polypropylene, and has 12 sharp protrusions 5 on the outer periphery and has a star shape, as shown in FIG. ing.

Note that the number of these protrusions 5 may be at least three, but preferably 10 to 15. Although these protrusions 5 are provided so as to be on the same plane, they may be slightly inclined in the same direction to create a slight difference in height between the center portion and the tips of the protrusions. The tips of the protrusions 5 are arranged on concentric circles so that the tips are in contact with the inner wall surface of the funnel 2. A hole 6 is bored in a portion of the chip removing member 3 other than the protrusion 5. These holes 6 have a shape that prevents the stirrer chips for stirring described above from passing through them, and can also be used as holes for the initials of a company's name, for example, to increase the advertising effect, as shown in FIG. The hole 6 may have various shapes such as a simple round shape or a square shape.

A regulating rod 4 is erected at the center of the chip removing member 3. In this embodiment, the regulating rod 4 passes through the chip removing member 3 at right angles, and as shown in FIG. A regulating rod 4 is attached to the removal member 3.
is becoming fixed. The lower tip 4a of the regulating rod 4 is connected to the funnel 2 as shown in FIGS.
is inserted into the discharge pipe 8 of the funnel 2, and the chip removing member 3 is tilted within the funnel 2 to prevent it from swinging. On the other hand, the upper end of the regulating rod 4 extends to the upper end injection port of the funnel 2 and serves as a knob for inserting and removing the chip remover 1.

When the regulating rod 4 is made separate from the chip removing member 3, it is preferably a thin rod made of a material that does not easily deform and has solvent resistance and heat resistance, for example, a glass rod is suitable.

In the above embodiment, the regulating rod 4 is made separately and passed through it, but it can be integrated with the chip removing member 3. Further, a regulating rod is provided upright in only one direction from the center of the chip removing member 3 so that it can be inserted into the discharge pipe 8 of the funnel 2, and a small protrusion serving as a knob is provided on the other side of the chip removing member 3. You can also do it.

Note that the regulating rod 4 inserted into the discharge pipe 8 of the funnel 2 must be smaller than the inner diameter of the discharge pipe 8 in order to smoothly discharge the liquid.

The regulation rod 4 is installed upright in the chip removal member 3 so as to be inserted into the discharge pipe 8 of the funnel. However, if the discharge pipe 8 of the funnel 2 is installed at an angle, the regulation rod 4 Needless to say, the chip removing member 3 is erected at a certain angle with respect to the chip removing member 3.

The funnel 2 is generally commercially available, and has a tapered injection part 9 and a discharge pipe 8 integrally formed at the tip thereof.

(Operation of the invention) The chip remover 1 described above is disposed at the inner lower part of the funnel 2, and the tip of the sharp protrusion 5 of the chip removing member 3 is supported in contact with the inner wall of the funnel 2. The tip 4a of the regulating rod 4 is guided and inserted into the discharge pipe 8 of the funnel 2, and the chip removing member 3
prevents it from swinging from side to side.

Therefore, when the organic synthesis reaction liquid stirred by the stirrer tip is injected into the funnel 2, the liquid flows through the holes 6 of the chip remover 1 and the gaps 11 formed between the adjacent protrusions 5. It flows out from the discharge pipe 8 through the discharge pipe 8. On the other hand, the stirrer chips that have fallen onto the chip remover 1 along with the liquid remain on the chip remover 1 as they are, and are taken out of the funnel 2 together with the chip remover 1 and separated from the liquid.

In the above embodiment, a stirrer chip was used as the chip, but it is needless to say that the chip is not limited to this.

(Effects of the invention) As explained above, according to the invention, chips are removed before reaching the funnel discharge pipe opening, so the discharge pipe opening is no longer blocked by chips, and liquid clogging is eliminated. Further, since the tip of the protrusion of the chip removing member that is in contact with the inner wall of the funnel makes point contact with the inner wall of the funnel, the amount of liquid that accumulates between the funnel wall surface and the tip of the protrusion is very small, and the liquid drains easily. Furthermore, there is an advantage that the chip remover can be easily inserted and removed.
