DETAILED DESCRIPTION

[0020] The technical solutions of the utility model will be described clearly and completely in combination with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0021] Please refer to Figures 1-3 The utility model provides a technical scheme:

[0022] The vacuum parallel concentration instrument 101 can accelerate the evaporation speed of the solution. Since the structural components and working principles of the vacuum parallel concentration instrument 101 are prior art, the specific structural components and working principles of the vacuum parallel concentration instrument 101 are not described in detail in this embodiment.

[0023] In this embodiment, the vacuum parallel concentration instrument 101 is provided with a turntable 201 and a water bath kettle 301, and a driving mechanism 401 for driving the turntable 201 to rotate. The turntable 201 is rotatably connected to the base of the vacuum parallel concentration instrument 101. Referring to Figure 2 The driving mechanism 401 includes a motor and a belt, and the turntable 201 and the output shaft of the motor are connected by the belt.

[0024] When the tail pipe bottles 901 are placed in the water bath kettle 301, in order to prevent the tail pipe bottles 901 from falling, a limiting frame 501 is installed in the water bath kettle 301, and a plurality of through holes are arranged on the limiting frame 501. In this way, each tail pipe bottle 901 is placed in each through hole, and the tail pipe bottles 901 will not be tilted when the water bath is heated.

[0025] In the heating process of the water in the water bath kettle 301 to the tail pipe bottles 901, in order to make the water in the water bath kettle 301 continuously impact the bottle body of the tail pipe bottles 901, increase the heat exchange speed between the tail pipe bottles 901 and the water, and quickly increase the temperature of the solution in the tail pipe bottles 901, so as to achieve the purpose of increasing the evaporation speed of the solution in the tail pipe bottles 901, an eccentric block 601 is installed on the turntable 201 in this embodiment. A counterbore 701 is formed in the eccentric block 601, and the central axis of the counterbore 701 is parallel to and not collinear with the central axis of the turntable 201. At the same time, a connecting pin (not shown in the figure) matched with the counterbore 701 is installed at the middle of the bottom of the water bath kettle 301. The connecting pin is inserted into the counterbore 701, and the water bath kettle 301 is installed on the eccentric block 601. At the same time, four flexible rods 801 are installed at the four corners of the bottom of the water bath kettle 301. The bottom end of any flexible rod 801 is connected to the base of the vacuum parallel concentration instrument 101, and the central axis of any flexible rod 801 is parallel to the central axis of the counterbore 701.

[0026] When the driving mechanism 401 drives the turntable 201 to rotate, the eccentric block 601 will also rotate synchronously, and the water bath pot 301 will also rotate synchronously, and the rotation of the water bath pot 301 will be converted into oscillation in the horizontal range under the action of the flexible rod 801, and the water in the water bath pot 301 and the solution in the tail pipe bottle 901 will also be oscillated, thereby improving the evaporation speed of the solution.

[0027] When the tail pipe bottle 901 is placed in the water bath pot 301, the bottle opening of the tail pipe bottle 901 needs to be sealed before heating. Therefore, in order to solve this problem, the water bath pot 301 in the embodiment is also provided with a sealing mechanism, which can seal the openings of the tail pipe bottles 901 when the tail pipe bottles 901 are placed in the water bath pot 301.

[0028] With reference to Figure 1 and Figure 3 , the sealing mechanism in the embodiment includes two synchronous driving motors 1001 symmetrically installed on both sides of the water bath pot 301, and each of the output shafts of the two driving motors 1001 is provided with an oscillating arm 1002, and the projections of the two oscillating arms 1002 on one side of the water bath pot 301 coincide. A sealing plate 1003 is installed between the two oscillating arms 1002, and the opposite sides of the sealing plate 1003 are each provided with two sliding blocks, and the two sliding blocks are respectively in sliding connection with the two oscillating arms 1002, and the sliding direction of the sliding blocks (i.e. the sliding direction of the sealing plate 1003) is the same as the extension direction of the oscillating arms 1002. A plurality of sealing pads 1004 are installed on the side wall of the water bath pot 301 close to the sealing plate 1003, and the plurality of sealing pads 1004 correspond one-to-one to the bottle openings of the plurality of tail pipe bottles 901 placed in the water bath pot 301. In this way, when the plurality of tail pipe bottles 901 are placed in the water bath pot 301, the presence of the limiting frame 501 makes each tail pipe bottle 901 be placed vertically, and then the two driving motors 1001 are started to make the two oscillating arms 1002 oscillate to the vertical position, and then the sealing plate 1003 falls to the top of the water bath pot 301 under the action of gravity, at this time each sealing pad 1004 abuts against the bottle opening of each corresponding tail pipe bottle 901, that is, the bottle opening of each tail pipe bottle 901 can be sealed.

[0029] During the oscillation of the water bath pot 301, if the oscillation amplitude of the water bath pot 301 is too large, the whole device may vibrate, which may damage other parts of the device. Therefore, in order to reduce the oscillation amplitude of the water bath pot 301, a counterweight 1101 is installed on the turntable 201 in the embodiment.

[0030] The above merely describes preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein, by the above teachings or related art or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the claims of the present application.
