Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a solution purification device for chemical laboratories. Background Art

[0002] Silver diammine hydroxide is an inorganic substance with the chemical formula Ag(NH3)2OH. The chemical reaction actually involves silver hydroxide, essentially AgOH·2NH3. Silver diammine hydroxide solution contains the following components: [Ag(NH3)2]+ ions, NH3 molecules, NH3·H2O molecules, NH4+ ions, OH- ions, and a very small amount of Ag+ ions. Silver diammine hydroxide is a complex compound with weak oxidizing properties, a strong base, and corrosive properties. It dissolves in water and ethanol and can be completely ionized. Silver ammonia solution is a commonly used solution reagent in chemical experiments.

[0003] However, in the process of preparing silver ammonia solution in the laboratory, since ammonia water needs to react with brown silver oxide precipitate, the process of preparing silver ammonia solution requires continuous shaking of the test tube to allow the ammonia water and the silver oxide solid precipitate to fully react. However, in the actual preparation process, insufficient shaking often leads to insufficient reaction between ammonia water and the silver oxide precipitate, resulting in low purity of diammine silver hydroxide in the silver ammonia solution, which reduces the accuracy of subsequent use of the reagent.

[0030] The following is combined with Figure 1-3 The utility model is described in further detail.

[0031] Example 1

[0032] like Figure 1-Figure 3 As shown, in order to solve the existing problems, the present invention discloses a solution purification device for a chemical laboratory in this embodiment, comprising a mounting plate 1 and a base 2 connected to the bottom thereof, an addition tank 3 connected to the mounting plate 1, a control valve 4 connected to the bottom of the addition tank 3, and a swing component 6 connected to the other side of the mounting plate 1;

[0033] The mounting plate 1 is rotatably connected to a swing member 7 , and the swing member 7 is provided with a limiting component 8 .

[0034] The swing component 6 includes a motor bracket 601 connected to the side of the mounting plate 1, the motor bracket 601 is connected to a rotating motor 602, the output end of the rotating motor 602 is connected to a turntable 603, the end of the turntable 603 away from the rotating motor 602 is rotatably connected to a rotating connecting rod 604, and the other end of the rotating connecting rod 604 is rotatably connected to a sliding rod 605;

[0035] Furthermore, the mounting plate 1 is provided with a sliding groove 606, the sliding rod 605 is slidingly connected to the inner wall of the sliding groove 606, the end of the sliding rod 605 away from the rotating connecting rod 604 is connected to a transmission member 607, the transmission member 607 is slidingly connected to a transmission rod 608, and the transmission rod 608 is connected to the swinging member 7.

[0036] The limiting component 8 includes an abutment member 801 connected to the side of the swing member 7, a sliding clamping member 802 is slidably connected to the side of the swing member 7, a rotating connection member 803 is connected to the top of the sliding clamping member 802, the rotating connection member 803 is rotatably connected to a rotating transmission rod 804, the other end of the rotating transmission rod 804 is rotatably connected to a threaded member 805, and the top of the swing member 7 is rotatably connected to a screw rod 806, which is threadedly connected to the threaded member 805;

[0037] Furthermore, an arc-shaped groove is provided on the side of the sliding clamping member 802 , an arc-shaped groove is provided on the side of the abutting member 801 , and two sliding clamping members 802 are symmetrically provided on the side of the swinging member 7 , and the two sliding clamping members 802 are symmetrically distributed on both sides of the abutting member 801 .

[0038] The specific working principle is: this device can achieve continuous shaking during the chemical reaction process, thereby avoiding problems such as insufficient reaction due to insufficient shaking, and thus achieving the purification preparation effect of the silver ammonia solution. When the device is used, the solution reagent tube containing silver oxide is placed between the sliding clamps 802 on both sides. At this time, the threaded part 805 can be moved upward by rotating the screw 806. The structure of rotating the transmission rod 804 can drive the rotating connecting parts 803 on both sides to approach each other, and then the sliding clamps 802 are brought close to each other. The combination of the sliding clamp 802 and the abutment part 801 can achieve clamping and fixation of reagent tubes of different diameters, thereby improving the clamping compatibility of the device.

[0039] When the reagent tube is clamped and fixed, the rotating motor 602 is started. The rotating motor 602 drives the turntable 603 to rotate. The rotation of the turntable 603 can rotate one end of the rotating connecting rod 604. The combination of the turntable 603 and the rotating connecting rod 604 can achieve the vertical reciprocating sliding effect of the sliding rod 605, thereby facilitating the subsequent shaking transmission effect of the swinging part 7.

[0040] Since the swinging of the swinging member 7 is an arc motion, and the sliding rod 605 is a vertical linear sliding, the combination of the transmission member 607 and the transmission rod 608 can drive the swinging member 7 to swing in an arc while the sliding rod 605 slides vertically linearly. The transmission rod 608 slides inside the transmission groove inside the transmission member 607, thereby avoiding the transmission jam of this device.

[0041] During the reciprocating swing of the swing member 7, if ammonia water is insufficient, when the swing member 7 is tilted toward the adding tank 3, ammonia water can be added to the inside of the reagent tube through the control valve 4, thereby ensuring the accurate preparation of the silver ammonia solution and avoiding the addition of excessive ammonia solution to the silver ammonia solution, which leads to a decrease in the concentration of the effective ingredients in the silver ammonia solution.

[0042] Example 2

[0043] like Figure 1-Figure 3 As shown, in order to solve the existing problems, based on the same concept as the above-mentioned embodiment 1, this solution purification device for a chemical laboratory further includes: a sliding groove is provided on the side of the swinging member 7, and a transmission groove is provided on the top of the swinging member 7. The sliding groove is connected to the inside of the transmission groove, and the sliding groove and the transmission groove are perpendicular to each other.

[0044] The base 2 is symmetrically distributed on both sides of the bottom of the mounting plate 1 , the adding tank 3 is distributed on the side of the swing member 7 , and the transmission member 607 is provided with a transmission groove, the inner wall of the transmission groove is slidably connected to the transmission member 607 .

[0045] The specific working principle is: this device avoids laboratory personnel from manually shaking the reagent tube, thereby avoiding splashing of ammonia or silver oxide solution due to manual shaking, and can reduce the operation difficulty of laboratory personnel. At the same time, this device can effectively improve the thoroughness of the reaction of the device through continuous and sufficient mixing effect.

[0046] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
