In addition, the three-dimensional spatial dimensions including length, width and depth should be included in actual manufacturing.

[0026] Please refer to the accompanying Figure 1 and Figure 2 The utility provides a mixing device for chemical reagent adjuvants, which comprises an outer shell 1, a reaction table 2 movably arranged inside the outer shell 1, lifting mechanisms 3 arranged on the left and right sides of the reaction table 2 for driving the reaction table 2 to ascend and descend, wherein a plurality of groups of air suction holes 5 are uniformly and penetratively arranged on the inner side of the outer shell 1, a gas collecting cover 51 is fixedly installed on the outer side of the air suction hole 5, and a negative pressure pipe 6 is connected to the outer side of the gas collecting cover 51.

[0027] In this embodiment, in the chemical reagent auxiliary mixing reaction, first, the reaction table 2 is lifted to the top of the outer shell 1 by the lifting mechanism 3, then the reaction beaker 7 is placed in the reaction table 2, and the chemical reagent auxiliary required for the experiment is poured into the reaction beaker 7, and then the reaction table 2 is lowered to the bottom of the outer shell 1 by the lifting mechanism 3. During the chemical reaction, the negative pressure generated in the negative pressure pipe 6 can suck the gas in the outer shell 1 through the air suction hole 5, so as to suck the toxic and harmful gas generated in the chemical experiment, and avoid the toxic and harmful gas from spreading to the outside to affect the safety of the experiment personnel;

[0028] In addition, the distal end of the negative pressure pipe 6 is connected to the negative pressure fan, so that the negative pressure fan can generate negative pressure in the negative pressure pipe 6, facilitate the adsorption of the toxic and harmful gas diffused into the outer shell 1, and the gas outlet of the negative pressure pipe 6 is extended to the outside, facilitating the discharge of the adsorbed toxic and harmful gas to the outside through the negative pressure pipe 6, avoiding harm to indoor personnel. When the gas outlet of the negative pressure pipe 6 cannot be extended to the outside, a purification device needs to be arranged at the gas outlet of the negative pressure pipe 6 to purify the toxic and harmful gas before discharging, reducing the harm to personnel;

[0029] Preferably, during the experiment, when the reaction of two reagents is relatively violent, or a large amount of gas is generated, in order to make the generated gas not spread to the outside as much as possible, the reaction beaker 7 needs to be placed behind the reaction table 2, and the reaction table 2 drives the reaction beaker 7 to descend to the outer shell 1. After various reagent auxiliaries are introduced into the reaction beaker 7 for experimental operation, the negative pressure fan needs to be turned on before the reagent is poured, so that a negative pressure environment is generated in the outer shell 1.

[0030] Please refer to Figure 2 As shown in the figure, the front and rear ends of the reaction table 2 are respectively slidably connected to the guide rod 21, and the lower end of the guide rod 21 is fixedly connected to the inner bottom end of the outer shell 1.

[0031] By slidably connecting the reaction table 2 to the guide rod 21, the reaction table 2 can be more stable during lifting or lowering, preventing it from shaking.

[0032] Please refer to Figures 2 to 4 As shown in the figure, the lifting mechanism 3 includes a guide wheel 32 fixedly installed at the top of the inner side wall of the outer shell 1, a winch 33 fixedly installed at the bottom of the outer shell 1, and a pulling rope 31 for lifting the reaction table 2. One end of the pulling rope 31 is tied to the reaction table 2, the other end of the pulling rope 31 is wound around the winch 33 through the guide wheel 32, and one end of the winch 33 is connected with a driving motor 34.

[0033] The lifting mechanism 3 can drive the reaction table 2 to ascend and descend in the outer shell 1. When the reaction table 2 is lifted, the driving motor 34 drives the capstan 33 to rotate, and the capstan 33 pulls the pulling rope 31, so that the reaction table 2 is lifted. When the reaction table 2 needs to descend, the driving motor 34 is reversed, the capstan 33 is reversed, the pulling rope 31 wound on the capstan 33 is loosened, the pulling of the reaction table 2 by the pulling rope 31 is loosened, and the reaction table 2 descends to the bottom of the outer shell 1 under the action of its own gravity.

[0034] The lifting mechanism 3 is provided in two groups and symmetrically arranged about the vertical center line of the reaction table 2.

[0035] Preferably, the two symmetrically arranged lifting mechanisms 3 are more stable when lifting the reaction table 2.

[0036] Please refer to Figure 2 and Figure 3 As shown, the suction cups 4 are provided in multiple groups on the reaction table 2, and the lower ends of the multiple groups of reaction tables 2 are connected to the gas collecting pipe 41. The lower end of the gas collecting pipe 41 is connected to the connecting pipe 42, and the other end of the connecting pipe 42 is in communication with the negative pressure pipe 6.

[0037] In this embodiment, the suction cups 4 can adsorb the reaction beaker 7 placed on the reaction table 2, so that the reaction beaker 7 is placed more stably on the reaction table 2. Specifically, the negative pressure generated by the negative pressure pipe 6 is connected to the connecting pipe 42, so that the negative pressure is generated in the gas collecting pipe 41. The negative pressure generated by the gas collecting pipe 41 causes the negative pressure to be generated in the suction cup 4, so that the bottom of the reaction beaker 7 is adsorbed.

[0038] The connecting pipe 42 is provided with a control valve 43.

[0039] The control valve 43 provided on the connecting pipe 42 can control the communication between the suction cup 4 and the negative pressure pipe 6. When negative pressure needs to be generated in the suction cup 4, the control valve 43 is opened. When the reaction beaker 7 needs to be removed from the reaction table 2, the control valve 43 can be closed to facilitate the removal of the reaction beaker 7.

[0040] In addition, in this embodiment, the outside of the device is electrically connected to a controller (not shown in the figure). The controller can control the rotation of the driving motor 34. In addition, the controller can control the driving motor 34 in the two lifting mechanisms 3 at the same time, so that the driving motor 34 works synchronously and stops synchronously, thereby being more stable when lifting the reaction table 2. In addition, the controller can control the working of the negative pressure fan. In addition, the control valve 43 is an electromagnetic valve, which can be opened and closed by the controller.

[0041] The utility model discloses a working principle is: in the chemical reagent auxiliary agent mixed reaction, first utilize the lifting mechanism 3 and lift the reaction stage 2 to the top of the outer casing 1, then place the reaction beaker 7 in the reaction stage 2, and pour the chemical reagent auxiliary agent required in experiment into the reaction beaker 7, then utilize the lifting mechanism 3 and drop the reaction stage 2 to the bottom of the outer casing 1, in the chemical reaction process, the negative pressure of negative pressure pipe 6 produces and will be through the gas hole 5 and inhale the gas in the outer casing 1 in the process, together with the toxic and harmful gas produced in the chemical experiment, avoid the toxic and harmful gas and spread to the outside and influence the personal safety of the experimental personnel.

[0042] The above only is the preferred implementation of the utility model, should point out, for the ordinary skill in the art, on the premise of not departing from the utility model principle, still can make a number of improvement and refinement, these improvements and refinements also should be regarded as the protection scope of the utility model.
