Description

Technical Field

[0001] This utility model belongs to the field of chemical experimental instrument technology, and in particular relates to a liquid exchange device for preparing chemical reagents and auxiliaries. Background Technology

[0002] Chemical reagents are widely used in various sectors of industry, agriculture, medical and health care, life sciences, inspection and quarantine, environmental protection, energy development, scientific research and national economy. They are used in chemical experiments, chemical analysis, chemical research and other experiments to carry out the mixing of chemical reagents in various purity levels. Sometimes, chemical experiments require mixing chemical reagents in proportion, so liquid exchange devices are needed to complete the liquid exchange.

[0003] Existing liquid exchange devices for chemical reagents and auxiliaries typically involve mixing two reagents (such as a mixture of acidic potassium permanganate and concentrated hydrochloric acid) and pouring them into the liquid exchange bottle for reaction. During the reaction, harmful gases such as chlorine are produced. Although some devices filter these gases by adding an exhaust pipe and a filter, in actual use, harmful gases can easily remain in the conduit leading to the gases. These harmful gases are then easily released when the mixed reagent is discharged, potentially harming the experimental operators. Therefore, we propose a new liquid exchange device for the preparation of chemical reagents and auxiliaries to address these problems. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0022] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0023] In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1: Refer to Figures 1-5 A chemical reagent and auxiliary preparation liquid exchange device includes a liquid exchange bottle 1 and a water bottle 2, which are connected by a conduit 3. A one-way valve is provided at the connection between the conduit 3 and the water bottle 2. An inlet pipe 11 is provided at the top of the liquid exchange bottle 1. The device also includes: a stirring rod 63, which is horizontally arranged inside the liquid exchange bottle 1; a jet nozzle 56, which is arranged in a ring-shaped inclined distribution inside the bottom of the water bottle 2; and an actuating element 4, which is located on one side of the water bottle 2, for extracting harmful gases remaining at the conduit 3 and then transporting them to the water bottle 2. At the same time, the actuating element 4 drives the stirring rod 63 to rotate inside the liquid exchange bottle 1 during operation.

[0025] In this invention, during the experimental operation, two reagents in a specific ratio, such as acidic potassium permanganate + concentrated hydrochloric acid, are poured into the liquid exchange bottle 1 through the inlet pipe 11. The inlet pipe 11 is then sealed, and the reaction takes place in the liquid exchange bottle 1. When the two reagents react chemically, the pressure inside the liquid exchange bottle 1 expands, and the generated chlorine gas is transported to the inside of the water bottle 2 through the conduit 3. Water is pre-filled into the water bottle 2. When the chlorine gas comes into contact with the water, it dissolves, facilitating the collection and treatment of the chlorine gas. After the natural reaction is complete, the chlorine gas is discharged through the inlet pipe 3. The starter 4 drives the stirring rod 63 to rotate, thereby disturbing the reagent inside the liquid exchange bottle 1, preventing some reagent liquid from not reacting fully, and improving the mixing effect of the reagent. At the same time, when the starter 4 reciprocates, it can extract the residual chlorine gas in the conduit 3 and then transport it to the inside of the water bottle 2. Due to the setting of the jet head 56, the extracted chlorine gas is output through the bottom of the water bottle 2, impacting the liquid inside the water bottle 2, accelerating the fusion of chlorine gas and water in the water bottle 2, improving the collection effect of the device and reducing the occurrence of gas-liquid stratification.

[0026] Example 2: Refer to Figure 2 and Figure 4 Similar to Embodiment 1, but further: the starting component 4 includes a fixing plate 40 fixed to the outer wall of the water bottle 2, a driving part 41 is installed on the fixing plate 40, a moving rod 42 is fixedly connected to the output end of the driving part 41, the moving rod 42 is provided with teeth, and a gear 61 is driven by the teeth meshing on the surface of the moving rod 42. A rotating shaft 62 is fixedly connected to the shaft center of the gear 61, and one end of the rotating shaft 62 passes through the liquid replacement bottle 1 and extends into the interior where a stirring rod 63 is fixedly connected. Both the liquid replacement bottle 1 and the water bottle 2 are provided with sensors, which are pressure sensors used to monitor the pressure values ​​inside the liquid replacement bottle 1 and the water bottle 2.

[0027] The drive unit 41 uses a reciprocating cylinder instead of a drive. When the natural reaction of the reagent in the liquid exchange bottle 1 ends, the drive unit 41 is activated to drive the moving rod 42 to move up and down reciprocally. The teeth on the surface of the moving rod 42 mesh with the gear 61, thereby driving the stirring rod 63 to rotate. Due to its horizontal arrangement, the stirring rod 63 can disturb the liquid at the bottom of the reagent in the liquid exchange bottle 1 when it rotates back and forth, so that the bottom of the reagent mixes with the bottom of the reagent, allowing the reagent to react fully. This prevents some reagents from failing to react fully during the actual preparation process, which would result in the generation of residual chlorine gas and affect the quality of the experimental reagent preparation. The pressure sensor is not shown in the figure, but a commonly used model on the market can be used to facilitate the monitoring of the pressure values ​​in the liquid exchange bottle 1 and the clear water bottle 2 during the experimental preparation process, thereby improving the stability of the liquid replacement of the device.

[0028] A piston 51 is fixedly connected to one end of the moving rod 42. The piston 51 is slidably connected inside the extraction cylinder 52. The extraction cylinder 52 is installed on the outer wall of the water bottle 2. A suction pipe 53 is fixedly connected to one end of the extraction cylinder 52. One end of the suction pipe 53 is connected to the conduit 3. A one-way valve is provided at the connection between the suction pipe 53 and the extraction cylinder 52. A gas supply pipe 54 is connected to one end of the extraction cylinder 52. A one-way valve is provided at the connection between the gas supply pipe 54 and the extraction cylinder 52. One end of the gas supply pipe 54 passes through the water bottle 2 and extends to the inside where it is fixedly connected to an annular pipe 55. A jet nozzle 56 is fixed on the surface of the annular pipe 55. A liquid inlet 21 is provided on the top outer wall of the water bottle 2. A sealing cap is provided on the liquid inlet 21. The annular pipe 55 is close to the bottom inner wall of the water bottle 2 but does not contact it. The diameter of the annular pipe 55 is smaller than the diameter of the water bottle 2.

[0029] When the moving rod 42 reciprocates, it drives the piston 51 to slide inside the extraction cylinder 52. The extraction cylinder 52 generates negative pressure, which can extract the residual chlorine gas at the conduit 3 and then transport it to the annular pipe 55 through the gas delivery pipe 54. Then, it is sprayed out through multiple jet nozzles 56, which are arranged in a ring shape and have an inclination angle of 40 degrees. After the gas is sprayed out, it rises from the bottom of the liquid in the water bottle 2, disturbing the liquid and causing centrifugal rotation, thereby accelerating the fusion of chlorine gas and water in the water bottle 2, improving the chlorine gas collection effect, and avoiding the occurrence of gas-liquid stratification.

[0030] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
