Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, specifically to a structure for a multi-tube vortex mixer device. Background Technology
[0002] A multi-tube vortex mixer is an experimental device used for mixing liquids or gases, and is widely used in fields such as chemistry, pharmaceuticals, food, and environmental protection. The multi-tube vortex mixer utilizes the vortex flow formed by rotating fluid within the tubes to generate a strong vortex effect, promoting rapid and uniform mixing of substances and effectively achieving the homogenization of different components.
[0003] In a multi-tube vortex mixer, sample tubes are typically secured by a vortex tube rack, which sits on the test tube platform and is positioned by an upper pressure plate that limits the tubes from the top. Therefore, to prevent the upper pressure plate from interfering with the placement and removal of test tubes from the vortex tube rack, the position of the upper pressure plate must be adjusted to move it away from the test tubes. In existing technology, the upper pressure plate is often installed by sliding a sleeve onto a slide rod and then secured with a locking screw. Adjusting the position of the upper pressure plate requires first unlocking the locking screw, then sliding the upper pressure plate to create sufficient operating space between the plate and the test tube, and finally tightening the locking screw to secure it. This process is cumbersome, inconvenient, and detrimental to experimental efficiency. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] A multi-tube vortex mixer device, such as Figures 1-3 As shown, its structural relationship is as follows: the multi-tube vortex mixer 2 is installed and fixed to the top of the base 1. The top of the multi-tube vortex mixer 2 is a test tube stand 3 for placing the vortex test tube rack 4. The upper pressure plate 6 is located above the test tube stand 3 and is installed to the base 1 through the height adjustment mechanism 5. The height adjustment mechanism 5 is provided with a vertical frame 51, a sliding block 53, a threaded screw 54, a screw nut 55, and a drive motor 56. The drive motor 56 is preferably a bidirectional motor. At the same time, in order to ensure the synchronicity of the drive of a pair of drive motors 56, a motor controller and a synchronizer should also be provided if necessary. The switch for controlling the drive motor 56 is preferably integrated into the multi-tube vortex mixer 2. The circuit connection method of the bidirectional motor is the prior art, and the control circuit and synchronous rotation method can be implemented by those skilled in the art through simple programming. It is common knowledge in the art. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.
[0035] A pair of vertical frames 51 are respectively provided on both sides of the upper pressure plate 6, and the vertical frames 51 have openings facing the upper pressure plate 6.
[0036] The sliding block 53 is fixedly connected to the lead screw nut 55. The lead screw nut 55 is slidably connected to the slide groove 52 through the sliding block 53, forming a vertical lead screw nut sliding pair between the lead screw nut 55 and the slide groove 52. The cross-section of the slide groove 52 is cross-shaped, and the shape of the sliding block 53 matches the slide groove 52. The threaded lead screw 54 is located in the slide groove 52, with its axis parallel to the lead screw nut sliding pair. One end of the lead screw nut 54 is shaft-connected to the output end of the fixedly installed drive motor 56, and the other end is rotatably connected to the vertical frame 51. The lead screw nut 55 and the threaded lead screw 54 are threadedly fitted together and fixedly installed with the upper pressure plate 6.
[0037] The aforementioned multi-tube vortex mixer device drives the threaded screw 54 to rotate via the drive motor 56. Under the limiting action of the slide groove 52, the screw nut 55 slides upward or downward within the slide groove 52. The upper pressure plate 6 rises or falls with the screw nut 55, realizing flexible adjustment of the height of the upper pressure plate 6. This greatly facilitates the installation and removal of the vortex test tube rack 4 and test tubes, simplifies the operation process of adjusting the height of the upper pressure plate, improves work efficiency, and can better adapt to the experimental needs of test tubes of different specifications (different heights).
[0038] Preferably, the lead screw 54 is rotatably connected to the vertical frame 51 via bearings at one end and near the other end, and the other end is shaft-connected to the output end of the drive motor 56. The bearing configuration helps ensure the smooth rotation of the lead screw 54.
[0039] like Figures 2-5 As shown, the vortex test tube rack 4 is provided with a pair of side plates 41 and a frame 42;
[0040] A pair of vertically arranged frame bodies 42 are located between a pair of side plates 41 and are connected and fixed to the pair of side plates 41 as an integral structure. Insertion holes 43 are densely arranged on the pair of frame bodies 42 in a corresponding manner. Insertion holes 43 for limiting the position of test tubes are densely arranged on the frame bodies 42.
[0041] Preferably, a limiting frame 44 with an opening facing the center of the insertion hole 43 is evenly distributed and fixed in the circumferential direction inside the insertion hole 43. The positioning plate 45 is slidably installed with the limiting frame 44, and the two form a positioning plate sliding pair in the radial direction of the insertion hole 43. The inner end of the positioning plate 45 extends out from the opening of the limiting frame 44. It is used to limit the test tube inserted into the insertion hole 43 from the side.
[0042] The limiting frame 44 is also threadedly fitted with a locking screw 46, which can press against the positioning plate 45 in a tightened state, thus limiting the relative sliding between the limiting frame 44 and the positioning plate 45.
[0043] In actual use, the radial installation position of the positioning plate 45 within the limiting frame 44 can be adjusted by sliding to accommodate the limiting needs of test tubes with different outer diameters. This setting allows test tubes with different outer diameters to be installed on the same vortex test tube rack for mixing in the same batch, which has good versatility and is conducive to simplifying the quantity of similar experimental supplies and controlling experimental costs.
[0044] Preferably, the inner end of the positioning plate 45 is arc-shaped to avoid damaging the test tube, and an ear block 47 is fixed at the top of the inner end. The operator can easily slide the positioning plate 45 inward or outward relative to the limiting frame 44 by applying force to the ear block 47.
[0045] The locking screw 46 is threaded and installed on the top of the limit frame 44.
[0046] like Figure 2and Figure 4 As shown, a limiting groove is provided on the test tube stand 3, and the vortex test tube rack 4 is placed in the limiting groove for limiting.
[0047] Preferably, the side plate 41 is made of magnetic material; a magnetic element is embedded in the limiting groove corresponding to the side plate 41, and the side plate 41 and the magnetic element are magnetically attracted. The magnetic element is preferably fixed by high-strength adhesive or installed and fixed in the limiting groove by threaded connector.
[0048] In actual use, the operator can use the limiting groove to keep the vortex test tube rack 4 in a stable position on the test tube stand 3. After it is placed stably, the side plate 41 and the magnetic component magnetically attract each other, further improving the stability of the vortex test tube rack 4.
[0049] When using the above-mentioned multi-tube vortex mixer to mix samples contained in test tubes, the following process is included:
[0050] The first step is to control the drive motor 56 to work, drive the threaded screw 54 to rotate in the forward direction, and drive the screw nut 55 to move upward under the guidance and limiting action of the slide groove 52. The upper pressure plate 6 rises with the screw nut 55, so that there is enough space between the test tube stage 3 and the upper pressure plate 6.
[0051] The second step is to place the vortex test tube rack 4 on the test tube stand 3 and embed the vortex test tube rack 4 into the limiting groove for limitation. At this time, the magnetic attraction between the side plate 41 made of magnetic material and the magnetic component makes the side plate 41 and the magnetic component firmly attracted and fixed.
[0052] The third step is to insert the test tubes containing the samples to be mixed into the corresponding sets of insertion holes 43 and fix them in place. The pair of insertion holes 43 on a pair of test tube racks 42 are one set of insertion holes.
[0053] The fourth step is to control the drive motor 56 to work, drive the threaded screw 54 to rotate in the opposite direction, and drive the screw nut 55 to move down under the guidance and limiting action of the slide groove 52. The upper pressure plate 6 follows the screw nut 55 to descend, so that the upper pressure plate 6 presses down to the top of the test tube.
[0054] Fifth step: Start the multi-tube vortex mixer 2 to mix the sample.
[0055] Step 6: Following the method in Step 1, raise the upper pressure plate 6 and remove the test tube containing the mixed sample.
[0056] Before the second step mentioned above, the vortex test tube rack 4 can be adjusted according to the outer diameter of the test tubes. The specific process is as follows:
[0057] (Using tools) Loosen the locking screw 46, apply force to the ear block 47, so that the positioning plate 45 slides radially inward or outward relative to the limiting frame 44 until the distance between the inner ends of each positioning plate 45 meets the limiting requirements of the test tube. Then (using tools) tighten the locking screw 46 again to fix the positioning plate 45 and the limiting frame 44 in place.
