Technical Field

The utility model relates to experimental equipment, in particular to an electric stirrer.

Background

In physical and chemical experiments, liquid is often required to be mixed, emulsified, dispersed and pulped, and the process is finished by placing a beaker filled with the liquid on a stirrer. Common stirrers in laboratories are magnetic stirrers and electric stirrers. The magnetic stirrer is mainly used for stirring low-viscosity mixtures and generally has a heating function. The electric stirrer is a simple mechanical stirrer and is suitable for various types of liquid.

The electric stirrer structurally drives the vertical stirring shaft to rotate by the motor, and the stirring shaft drives liquid to form vortex motion to realize a stirring function. The liquid has a certain height in the beaker, the stirring shaft is generally small in diameter and small in contact area with the liquid, and the time is long for stirring the liquid fully. Sometimes, in order to stir fully, the height of the stirring shaft needs to be adjusted to different heights for stirring for multiple times, which is inconvenient to use.

Above-mentioned electric mixer, the upper end slidable cover of vice pole is established on the annular frame, the left and right sides of vice pole is equipped with the spring, the spring cover is established on the annular frame.

Above-mentioned electric mixer, the lower extreme of vice pole and mobile jib all is equipped with the stirring piece that thickness is 1~3mm, be equipped with the several through-hole on the stirring piece.

Above-mentioned electric mixer, the ring heart department of annular frame is equipped with the opening cover, opening cover outer wall is equipped with the external screw thread, the body of rod of mobile jib wears to establish after the opening cover with fastening nut spiro union in the upper and lower both ends of opening cover.

According to the electric mixer, the upright post is provided with the vertical sliding groove, the motor box is provided with the sliding block matched with the sliding groove, the left side and the right side of the upright post are provided with the strip holes, and the locking bolts penetrate through the strip holes and are in threaded connection with the sliding block.

Above-mentioned electric mixer, the chuck that is used for the clamping mobile jib is installed to the motor shaft end in the motor case.

The beneficial effects of the utility model are as follows: the stirring component is arranged into a structure of the main rod and the auxiliary rod, so that the contact area of the stirring component and liquid is increased, and the stirring uniformity and efficiency are improved. The auxiliary rod is of a movable structure, and the position on the annular frame is micro-moved during rotation, so that irregular movement of liquid is realized, and the effect of full stirring can be achieved more quickly. Meanwhile, the relative position of the auxiliary rod and the main rod in the vertical direction is adjustable, and the position of the auxiliary rod can be adaptively adjusted according to different liquid heights.

FIG. 2 is a side view of the present invention;

FIG. 3 is an enlarged partial schematic view of the stirring member of the present invention;

FIG. 4 is a schematic view of the structure of the stirring member of the present invention.

In the figure: the device comprises a base plate 1, a stand column 2, a motor box 3, a locking bolt 4, a chuck 5, a main rod 6, a fastening nut 7, an annular frame 8, an auxiliary rod 9, a stirring piece 10, a spring 11 and a strip hole 21.

Detailed Description

The present invention will be described in detail with reference to the drawings, in which the directions "up, down, left and right" are determined based on the orientation in the front view.

The embodiment is an electric mixer for laboratory stirring all kinds of liquid, including bottom plate 1, stand 2, motor case 3 and stirring part, stand 2 is vertical to be established on bottom plate 1, motor case 3 is installed on stand 2, stirring part is rotatory by the motor drive in the motor case 3. The clamp 5 is arranged at the end of the motor shaft in the motor box 3, so that the main rod 6 can be conveniently clamped, and the clamp 5 is similar to a clamping type clamp used on an electric drill or a drilling machine.

The motor case 3 can be slidably adjusted in position in the column. Be equipped with vertical spout on the stand 2, be equipped with the slider that matches with the spout on the motor case 3, the left and right sides of stand 2 is equipped with rectangular hole 21, passes rectangular hole 21 and spiro union in slider with locking bolt 4.

Specifically speaking, the stirring part includes mobile jib 6 and two auxiliary rod 9, the body of rod of mobile jib 6 is gone up the level and is equipped with the annular frame 8 that uses mobile jib 6 as the centre of a circle, guarantees that the centre-to-centre spacing between two auxiliary rod 9 does not exceed 80mm, can be applicable to most laboratory common containers such as beakers.

The upper end slidable of vice pole 9 is established on annular frame 8, the left and right sides of vice pole 9 is equipped with spring 11, and he spring 11 cover is established on annular frame 8, so when rotatory position of vice pole 9 on annular frame be the fine motion, thereby the motion of messenger's liquid appears irregular phenomenon can be more quick reach the abundant effect of stirring.

For further improving stirring efficiency, avoid the heavy end of particulate matter in the liquid, the lower extreme of vice pole 9 and mobile jib 6 all is equipped with the stirring piece 10 that thickness is 1~3mm, be equipped with the several through-hole on the stirring piece 10, increase and the area of contact of bottom liquid.

The mounted position between annular frame 8 and the mobile jib 6 is adjustable, specific saying so the ring heart department of annular frame 8 is equipped with the opening cover, opening cover outer wall is equipped with the external screw thread, the body of rod of mobile jib 6 wears to establish after the opening cover with fastening nut 7 spiro union in the upper and lower both ends of opening cover. When the liquid is less (lower), the annular frame 8 can be adjusted lower to make the auxiliary rod 9 longer than the main rod 6; when the liquid is more (higher), the annular frame 8 can be heightened to enable the lower end of the auxiliary rod 9 to be shorter than the main rod 6, and as shown in fig. 1, the auxiliary rod 9 can stir the upper part of the liquid, so that the whole stirring is more uniform.
