Description

Technical Field

[0001] This utility model relates to the field of production technology of multi-threaded gradual liquid dispensing device, and in particular to a multi-threaded gradual liquid dispensing device. Background Technology

[0002] A multi-threaded gradient dispensing device refers to a device with multiple independently or semi-independently controlled dispensing channels ("threads"), capable of simultaneously dispensing liquid to multiple target containers, greatly improving work efficiency. Gradual dispensing means that the flow rate or volume of each dispensing channel can change smoothly and continuously according to a preset program (such as linear, exponential, S-curve, etc.), rather than simply "on / off" or a fixed flow rate. This is crucial for applications requiring dynamic changes in reaction conditions or the preparation of gradient materials.

[0003] When the solution is gradually added into the reaction tank, it can undergo a chemical reaction. However, after the reaction, a certain amount of metal will precipitate at the bottom of the reaction tank. The precipitated metal may stick to the inner wall of the bottom of the reaction tank, making it difficult to feed the solution.

[0004] Therefore, how to provide a multi-threaded gradual dispensing device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a multi-threaded gradual liquid addition device, which addresses the problem mentioned in the background art where precipitated metal may stick to the inner wall at the bottom of the reaction tank, making it difficult to dispense the material.

[0006] A multi-threaded gradual liquid addition device according to an embodiment of the present invention includes a reaction chamber. A sealing plate is installed on one side of the reaction chamber, and a three-channel multi-head peristaltic pump is installed on the top of the reaction chamber. The outlet end of the three-channel multi-head peristaltic pump is equipped with a conduit that penetrates and extends into the reaction chamber. A pushing mechanism is provided inside the reaction chamber, and the pushing mechanism includes a mounting frame, a protective cylinder, a piston plate, an electric cylinder, a movable rod, and a push plate. A protective cylinder is fixedly installed on one side of the reaction chamber, a mounting frame is fixedly installed on the bottom of the reaction chamber, an electric cylinder is fixedly installed on the top of the mounting frame, a movable rod that penetrates and extends into the reaction chamber is fixedly installed on the output shaft of the electric cylinder, a piston plate adapted to the protective cylinder is fixedly installed on the outer ring of the movable rod located inside the protective cylinder, and a push plate is fixedly installed on one end of the movable rod located inside the reaction chamber.

[0007] As a preferred embodiment of this utility model: a placement rack is fixedly installed on both sides of the reaction box, and three liquid-containing tanks are fixedly installed on the top of the placement rack.

[0008] As a further preferred embodiment of this utility model: each of the three liquid tanks is equipped with a flexible tube at one end, and the other end of each of the three flexible tubes is connected to a three-channel multi-head peristaltic pump.

[0009] As a further preferred embodiment of this utility model: each of the three liquid-containing tanks is fixedly equipped with a feed pipe on its top, and the top of each of the three feed pipes is closed by a cover plate.

[0010] As a further preferred embodiment of this utility model: a motor is fixedly installed on the top of the reaction chamber, and a rotating shaft is fixedly installed on the output shaft of the motor, and the rotating shaft passes through and extends into the reaction chamber.

[0013] As a further preferred embodiment of this utility model:

[0014] The beneficial effects of this utility model are:

[0015] 1. The electric cylinder is activated to move the movable rod, which in turn moves the push plate. This pushes some metal that has settled at the bottom of the reaction tank, making it easier to loosen the settled metal and facilitate subsequent material feeding. When the movable rod moves, it can move the piston plate inside the protective cylinder, which can prevent leakage at the connection between the movable rod and the reaction tank.

[0016] 2. When different solutions need to be added to the reaction tank, a three-channel multi-head peristaltic pump is used to control the addition of solutions from the corresponding liquid tanks. The solutions are delivered to the conduit through a hose and then added to the reaction tank. The motor is then started to rotate the shaft and the stirring plate, which gently stirs the gradually added liquids, accelerating their fusion and thus the reaction. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1 As shown in Figures 1, 2, and 3, the reaction chamber includes a reaction chamber 1. A sealing plate 17 is installed on one side of the reaction chamber 1. A three-channel multi-head peristaltic pump 11 is installed on the top of the reaction chamber 1. The outlet end of the three-channel multi-head peristaltic pump 11 is equipped with a conduit 12 that penetrates and extends into the reaction chamber 1. The reaction chamber 1 is equipped with a pushing mechanism, which includes a mounting frame 10, a protective cylinder 9, a piston plate 8, an electric cylinder 7, a movable rod 6, and a push plate 5. A protective cylinder 9 is fixedly installed on one side of the reaction chamber 1. A mounting frame 10 is fixedly installed on the bottom of the reaction chamber 1. An electric cylinder 7 is fixedly installed on the top of the mounting frame 10. A movable rod 6 that penetrates and extends into the reaction chamber 1 is fixedly installed on the output shaft of the electric cylinder 7. A piston plate 8 that is compatible with the protective cylinder 9 is fixedly installed on the outer ring of the movable rod 6 located inside the protective cylinder 9. A push plate 5 is fixedly installed on one end of the movable rod 6 located inside the reaction chamber 1.

[0025] The start-up of the electric cylinder 7 drives the movable rod 6 to move, which in turn moves the push plate 5. This pushes some metal deposited at the bottom of the reaction tank 1, making it easier to loosen the deposited metal and facilitate subsequent material feeding. When the movable rod 6 moves, it can drive the piston plate 8 to move inside the protective cylinder 9, which can prevent leakage at the connection between the movable rod 6 and the reaction tank 1.

[0026] refer to Figure 1As shown in Figures 1, 2, and 3, a placement rack 15 is fixedly installed on both sides of the reaction chamber 1. Three liquid collection tanks 13 are fixedly installed on the top of the placement rack 15. A hose 16 is installed at one end of each of the three liquid collection tanks 13. The other ends of the three hoses 16 are respectively connected to a three-channel multi-head peristaltic pump 11. A feed pipe 14 is fixedly installed on the top of each of the three liquid collection tanks 13. The top of each of the three feed pipes 14 is closed by a cover plate. A motor 2 is fixedly installed on the top of the reaction chamber 1. A rotating shaft 3 is fixedly installed on the output shaft of the motor 2. The rotating shaft 3 passes through and extends into the reaction chamber 1. Three sets of stirring plates 4 are fixedly installed on the outer ring of the rotating shaft 3 inside the reaction chamber 1. A feed hopper 19 is fixedly installed on the top of the reaction chamber 1. A drain pipe 18 is fixedly installed on one side of the reaction chamber 1.

[0027] The starting motor 2 drives the rotating shaft 3 to rotate, which in turn drives the stirring plate 4 to rotate. This can gently stir the gradually added liquid, accelerate its fusion, and thus accelerate its reaction. When gradual addition is required, the three liquid tanks 13 are respectively filled with Cu(NO3)2 solution (containing sodium citrate inhibitor), silver ammonia solution, and EDTA-2Na complexing agent solution. When gradual addition is required, the solution in the liquid tank 13 is controlled by the three-channel multi-head peristaltic pump 11, which can deliver the solution in the liquid tank 13 to the conduit 12 through the hose 16 and drip it into the reaction tank 1, which can accelerate the reaction in the reaction tank.

[0028] Working principle: When different solutions need to be added to the reaction tank 1, the three-channel multi-head peristaltic pump 11 controls the addition of the solution to the corresponding liquid tank 13. The solution is then transported to the conduit 12 through the hose 16 and added to the reaction tank 1. Then, the motor 2 is started to drive the rotating shaft 3 to rotate, which in turn drives the stirring plate 4 to rotate. This gently stirs the gradually added liquid, accelerating its fusion and reaction. After the reaction in the reaction tank 1 has settled, the liquid in the reaction tank 1 is discharged through the drain pipe 18. Then, the sealing plate is opened, and the electric cylinder 7 is started to move the movable rod 6, which in turn moves the push plate 5 inside the reaction tank 1. This pushes the metal that has settled at the bottom of the inner wall of the reaction tank 1, facilitating the discharge of the material after the reaction and sedimentation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
