Description

  The present invention relates to a holder for attaching a separatory funnel, which is a kind of shaking container, to a shaking plate.

  Put two or more kinds of mutually insoluble liquid in a shaking container, mix the liquid by shaking the shaking container, and shake and shake the shaking container up and down as a shaker that extracts and concentrates the target substance into one liquid A so-called vertical shaker is known. This vertical shaker reciprocates in the vertical direction on the side of a box containing a drive motor and a crank mechanism that converts the rotational motion of the drive motor into reciprocating motion by a connecting rod connected to the crank mechanism. A guide member for guiding the moving shake plate is provided, the shake vessel is mounted on the shake vessel holder attached to the shake plate, and the shake plate is reciprocated in the vertical direction along the side surface of the box by the rotation of the drive motor. Shake the liquid in the shaking container.

  A test tube, a flask, a separatory funnel or the like is used as a shaking container. Each of these shaking containers is attached to a shaking plate via a dedicated holder. Among them, the separator funnel holder is compatible with separator funnels of different sizes, so that it can be slid onto the support column, a vertical support column that can be attached to and detached from the shaking plate, a support arm fixed to the lower end of the support column, And holding the stopper of the separatory funnel reversed by the support arm, and holding the valve of the separatory funnel reversed by the holder arm (for example, Patent Document 1). reference).

The separatory funnel is mounted by placing an elastic material such as a coil spring on the stopper receiving part of the support arm, placing the stopper of the separatory funnel on the elastic material, and then lowering the holding arm to separate the liquid. Press the funnel valve to compress the elastic material and fix the holding arm to the support column with screws, pins, etc. at an appropriate holding pressure, or lock the holding arm by locking the ratchet to the rack provided on the support column The separatory funnel was held between the holding arm and the support arm.

  As described above, according to the present invention, since the holding arm is urged in the downward direction by the spring member, when the separatory funnel is mounted, the separatory funnel in which the holding arm is lifted upward and reversed. Since the holding arm presses and holds the separatory funnel from above by simply holding the stopper on the support arm and making it contact the valve of the separatory funnel with the holding arm reversed, it is easy to attach and detach the separatory funnel And it can be done for a short time. Further, by providing a stopper for restricting the lowering of the holding arm on the support column, the holding arm does not descend to the bottom of the support column, so that the mounting time of the separatory funnel can be shortened.

  Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. The separatory funnel holder 4 attached to the shaker plate 3 of the vertical shaker 2 by holding the separatory funnel 1 containing two or more kinds of mutually insoluble liquids in an inverted manner is detachably attached to the shaker plate 3. Directional strut 5, a support arm 7 that supports the stopper 6 of the separatory funnel 1 fixed to the lower end of the strut 5 and reversed, and slidably provided on the strut 5 and reversed. A holding arm 9 that presses and holds the valve 8 of the separatory funnel 1 from above is provided.

  The column 5 has a front plate 5a and both side plates 5b and 5b, and has a shape in which the back side which is the side of the shaking plate 3 is opened, and a holding portion 5c of the drum 10 is formed below the side plates 5b and 5b. The mounting portion 5d to the shaking plate 3 is fixed on the upper back side. A drum holder 12 having a U-shaped cross section provided with a horizontal shaft 11 that rotatably supports the drum 10 is fixed to the holding portion 5c.

  The support arm 7 includes a bottom member 7c having a bottom plate 7a and both side plates 7b, 7b, and a plug receiving plate 7d that closes the front and upper sides of the side plates 7b, 7b of the bottom member 7c. The attachment portions 7e to the shaking plate 3 are bent and formed on the back surfaces of the side plates 7b and 7b. The support arm 7 is fixed to the lower end of the support column 5 on the back side of the bottom member 7c. In the stopper receiving plate 7d, a mounting hole 7f for the stopper receiver 13 for supporting the stopper 6 of the separatory funnel 1 is formed. The stopper receiver 13 is formed of an elastic material such as a soft resin, and has a recess 13a into which the stopper 6 is inserted.

  The holding arm 9 has a front plate 9a, both side plates 9b, 9b and a top plate 9c, and holds both side plates 5b, 5b of the column 5 by the side plates 9b, 9b. , 9b are formed longer on the back side than the side plates 5b, 5b at a wider interval than the side plates 5b, 5b of the support column 5. Sliding plates 9d and 9e are attached to the side plates 9b and 9b with the front plate 5a of the support column 5 sandwiched from the front and rear sides. A retaining plate 9f that maintains the distance between the retaining arm 9 and prevents the holding arm 9 from falling off the support column 5 is fixed, and a spacer 9g is provided between the retaining plate 9f and the rear sliding plate 9e. ing. A bifurcated holding member 9h for pressing and holding the valve 8 of the separatory funnel 1 from above is attached to the front plate 9a.

In the present embodiment, a belt spring 14 having a constant load of 2 kg is wound around the drum 10 with its base end fixed and wound. The rear surface of the front plate 5a is extended upward and is connected to the sliding plate 9e on the rear side of the holding arm 9. As a result, the holding arm 9 is urged by the belt spring 14 in the downward direction. Further, a stopper 15 for restricting the lowering of the holding arm 9 is attached to the lower part of the holding arm 9 with a screw 16. The mounting position of the stopper 15 is preferably slightly lower than the valve of the smallest separatory funnel. As a result, the holding arm 9 does not descend to the bottom of the support column 5, so that the separatory funnel 1 is attached. You can save time.

  The separatory funnel holder 4 configured in this manner is attached to the shaking plate 3 by screwing the attaching portion 5d of the support column 5 and the attaching portion 7e of the support arm 7 to the shaking plate 3. Then, the stopper 6 of the separator funnel 1, which has been reversed by pulling up the holding arm 9 of the separator funnel holder 4, is inserted into the recess 13 a of the stopper receiver 13 of the support arm 7, and the holding member 9 h of the holder arm 9 is inserted. By fitting the pipe of the separatory funnel 1 into the fork and releasing the holding arm 9, the holding arm 9 is lowered by the urging force of the belt spring 14, and the valve 8 of the reversed separatory funnel 1 is pressed from above. Holding, the separatory funnel 1 is attached to the separatory funnel holder 4. When removing the separatory funnel 1, if the holding arm 9 is pulled upward, the pressing and holding is released and the separatory funnel 1 can be removed.

  Therefore, the attaching / detaching operation of the separatory funnel 1 can be easily performed. Further, even a separation funnel having the same trunk diameter and a different distance from the stopper 6 to the valve 8 can be easily mounted. Further, as shown in FIG. 5, the large-capacity separatory funnel 1 having a large trunk diameter can be mounted by allowing the holding member 9 h of the holding arm 9 to slide in the front-rear direction.

  The vertical shaker 2 reciprocally shakes the shaking plates 3 provided on both side surfaces of the casing 21 in a vertical state or at a desired inclination angle in the vertical direction. A drive mechanism for reciprocating the plate 3 in the vertical direction and a tilt mechanism for fixing the shaking plate 3 to a vertical state or a desired tilt angle are provided.

  The drive mechanism includes a drive motor (not shown) installed in the casing 21, a crank mechanism 22 that converts the rotation of the drive motor into a reciprocating motion, and a shaking plate 3 that is connected to the crank mechanism 22 and moves the shaking plate 3 up and down. A connecting rod 23 that reciprocates in the direction and a guide member 25 that guides the shaking plate 3 through a plurality of guide rollers 24 so as to be movable in the vertical direction.

  The tilt mechanism includes a guide member support plate 26 fixed to both side surfaces of the casing 21, a horizontal support shaft 27 provided on the guide member support plate 26 and supporting the upper portion of the guide member 25. A shaking plate fixed position knob 29 that is inserted into an arc-shaped elongated hole 28 formed in the guide member support plate 26 and is screwed into the lower portion of the guide member 24.

  As a result, the guide member 25 can be tilted with respect to the casing 21 by rotating about the support shaft 27, so the shaking plate predetermined position fixing knob 29 is set at a desired angle. By tightening, the shaking plate 3 is fixed to a vertical state or a desired inclination angle, and reciprocally shakes in the vertical direction by operation of the drive motor.

  When the shaking plate 3 is tilted and shaken, the contact area of each liquid in the separatory funnel 1 becomes larger than that in the vertical state, and each liquid has a vertical force due to gravity and the shaking plate 3 Due to the force of the combined motion of the horizontal force by the product of the amplitude and the tilt angle, the fluid interface is disturbed by the frictional motion with the inner wall of the separatory funnel 1, and each liquid becomes agitated from the low speed stage, and the vertical shaking Compared to the above, the stirring force is increased, the shaking time can be shortened, vibration and noise can be reduced, and the mechanical burden can be reduced. Moreover, even if the shaking speed is reduced to 2/3 of the conventional method, the same degree of shaking effect can be obtained. In this case, extremely quiet operation is possible, and mechanical wear can be reduced and power can be saved. .
