Description

Technical Field

[0001] This application relates to the field of solution preparation technology, specifically a multi-channel preparation device for inorganic standard solutions. Background Technology

[0002] The preparation of inorganic standard solutions is a crucial task in many fields, including chemical analysis, environmental monitoring, and biomedicine. Traditional methods for preparing inorganic standard solutions often rely on manual operation, which is not only inefficient but also prone to human error, making it difficult to guarantee the accuracy of the solution preparation. With advancements in technology and the development of automation, automated preparation devices for inorganic standard solutions have emerged.

[0003] However, while existing automated inorganic standard solution preparation devices can meet the requirement of simultaneous preparation through multiple channels, in actual operation, due to the physical and chemical properties of the solution itself, such as viscosity and adhesion, residues are easily generated during the preparation process, especially at the junctions where multiple preparation tubes converge, thus affecting the accuracy of solution preparation.

[0037] Preferably, a limiting frame 111 is fixedly installed on the mounting plate 11 at the position corresponding to the impact rod 81. The limiting frame 111 has a guide hole 1111, and the impact rod 81 is slidably connected in the guide hole 1111.

[0038] Preferably, an impact disc 811 is fixedly installed at one end of the impact rod 81 near the inlet tank 3, and the diameter of the impact disc 811 is larger than the diameter of the guide hole 1111.

[0041] Preferably, the liquid dispensing pipe 5 has an inclined surface 51 fixedly provided inside, and the inclined surface of the inclined surface 51 gradually decreases from front to back.

[0042] The preferred embodiments of the present invention are described below with reference to the accompanying drawings, and the present invention will be further described in detail.

[0043] This embodiment provides a multi-channel preparation device for inorganic standard solutions, such as... Figure 1-5 As shown, the multi-channel preparation device includes a housing 1, multiple storage tanks 2 placed inside the housing 1, a mounting plate 11 fixedly mounted on the housing 1 corresponding to one side of the storage tanks 2, a receiving tank 3 fixedly mounted on the mounting plate 11, a mixing tank 4 rotatably connected to the mounting plate 11 and rotatably connected to the bottom of the receiving tank 3, a dispensing pipe 5 penetrating the housing 1 and connected at both ends to the storage tanks 2 and the receiving tank 3 respectively, a metering pump 6 fixedly mounted on the dispensing pipe 5 near one end of the storage tank 2, and a drive mechanism 7 mounted on the mounting plate 11 for driving the mixing tank 4 to rotate. The mixing tank 4 and the receiving tank 3 are connected to the receiving tank 3. The tank 3 is connected; the multi-channel preparation device also includes an inclined surface 51 fixedly installed in the liquid dispensing pipe 5 near the inlet tank 3 and an impact mechanism 8 installed on the mounting plate 11 and connected to the drive mechanism 7 for vibrating the inlet tank 3. The lower end of the inclined surface 51 is located at the connection between the liquid dispensing pipe 5 and the inlet tank 3; the impact mechanism 8 includes an impact rod 81 that moves laterally on the mounting plate 11 corresponding to one side of the inlet tank 3 for impacting one side of the inlet tank 3 and a transmission assembly 82 installed on the mounting plate 11 and connected to the drive mechanism 7 for transmitting the power of the drive mechanism 7 to the impact rod 81.

[0044] In order to facilitate the discharge of the mixed solution, a valve 41 is fixedly installed at the bottom of the mixing tank 4. The design of the valve 41 allows the mixed solution in the mixing tank 4 to be discharged simply by opening the valve 41 after mixing, and the mixing tank 4 to be sealed when mixing by closing the valve 41 during mixing, thus simplifying the operation process.

[0045] Before mixing the solutions, ensure valve 41 is closed. Then, turn on metering pump 6 to draw the required solution from the corresponding storage tank 2 and into the corresponding dispensing pipe 5. Once in the dispensing pipe 5, the solution is guided by inclined plane 51 and delivered to the receiving tank 3. Simultaneously, start drive mechanism 7 to rotate mixing tank 4. After all the solution has been added to receiving tank 3, it flows directly into mixing tank 4. The rotation of mixing tank 4 ensures thorough mixing of the solutions entering it. Because transmission component 82 is connected to drive mechanism 7, the solution is fully mixed. During the rotation of the mixing tank 4 driven by the drive mechanism 7, the transmission component 82 will synchronously drive the impact rod 81 to repeatedly impact the inlet tank 3. The impact of the impact rod 81 will cause the inlet tank 3 to vibrate, which will be transmitted to the dispensing pipe 5 and the mixing tank 4. The vibration of the inlet tank 3 and the dispensing pipe 5 can reduce the residue of the dispensing solution in the dispensing pipe 5 and the inlet tank 3, and can directly flow into the mixing tank 4 for mixing. In addition, the vibration of the mixing tank 4 can further promote the mixing of the solution. After the mixed solution is obtained, the drive mechanism 7 is stopped, and the valve 41 is opened to discharge the obtained solution from the mixing tank 4.

[0046] Specifically, the drive mechanism 7 includes a gear ring 71 fixedly sleeved on the outside of the mixing tank 4 and rotatably disposed in the mounting plate 11, a connecting shaft 73 longitudinally penetrating one side of the mounting plate 11 corresponding to the gear ring 71 and rotatably connected to the mounting plate 11, a gear 72 fixedly sleeved on the connecting shaft 73 and meshing with the gear ring 71, and a motor 74 fixedly disposed at the bottom end of the connecting shaft 73 corresponding to the mounting plate 11 for driving the connecting shaft 73 to rotate.

[0047] When the solution is transported to the receiving tank 3 through the dispensing pipe 5 and then to the mixing tank 4 through the receiving tank 3, the motor 74 is started. At this time, the motor 74 will drive the connecting shaft 73 connected to it to rotate. Since the connecting shaft 73 is connected to the gear 72, the gear 72 will also rotate synchronously as the connecting shaft 73 rotates. Since the gear 72 meshes with the gear ring 71 connected to the mixing tank 4, the mixing tank 4 will also rotate synchronously as the gear 72 rotates. As the mixing tank 4 rotates, the solution entering the mixing tank 4 will be subjected to centrifugal force, and thus mixing will occur.

[0048] Furthermore, the transmission assembly 82 includes a rotating wheel 821 fixedly connected to the top of the connecting shaft 73 and located on one side of the inlet tank 3, an eccentric rod 822 fixedly connected to the rotating wheel 821, and a connecting rod 823 whose two ends are movably connected to the eccentric rod 822 and the impact rod 81 respectively on the side away from the inlet tank 3.

[0049] When the starting motor 74 drives the connecting shaft 73 to rotate, since the top end of the connecting shaft 73 is connected to the rotating wheel 821, the rotating wheel 821 will also rotate synchronously as the connecting shaft 73 rotates. Since the rotating wheel 821 is connected to the eccentric rod 822, and the eccentric rod 822 is eccentrically set, when the rotating wheel 821 rotates, the eccentric rod 822 will be subjected to centrifugal force to drive the connecting rod 823 to reciprocate. The other end of the connecting rod 823 will transmit the reciprocating motion to the impact rod 81 under the sliding guide of the impact rod 81, so that the impact rod 81 reciprocates to impact the merging tank 3, causing the merging tank 3, the liquid distribution pipe 5 and the mixing tank 4 to vibrate.

[0050] Understandably, in order to ensure the movement of the impact rod 81, a limit frame 111 is fixedly installed on the mounting plate 11 at the position corresponding to the impact rod 81. The limit frame 111 has a guide hole 1111, and the impact rod 81 is slidably connected in the guide hole 1111. The design of the limit frame 111 and the guide hole 1111 ensures the stability and accuracy of the impact rod 81 during movement. The guide hole 1111 provides a fixed movement path for the impact rod 81, avoiding the impact effect from shaking or deviation. At the same time, the limit frame 111 also plays the role of supporting and fixing the impact rod 81, enhancing the structural stability of the entire device. In addition, to prevent the impact rod 81 from moving away from the limiting frame 111, an impact disc 811 is fixedly installed at the end of the impact rod 81 near the inlet tank 3. The diameter of the impact disc 811 is larger than the diameter of the guide hole 1111. The larger diameter of the impact disc 811 effectively prevents the impact rod 81 from moving away from the limiting frame 111. This design not only improves the stability and reliability of the impact rod 81, but also avoids the safety hazards caused by the impact rod 81 falling off. At the same time, the impact disc 811 can also increase the impact area and improve the impact effect.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
