Description

Technical Field

[0001] The utility model relates to the technical field of adsorption devices, in particular to a macroporous resin adsorption and desorption device. Background Art

[0002] Macroporous resin is mainly made of raw materials such as styrene and divinylbenzene. Its physical and chemical properties are stable, and it can resist the erosion of acids, alkalis and various organic solvents. Its unique property lies in its high selective adsorption ability for organic substances. This process is hardly interfered by inorganic salts, strong ions or low-molecular compounds. Through the physical adsorption mechanism, macroporous resin can accurately capture and enrich target organic substances from complex solution systems, so as to achieve the goal of efficient separation and purification.

[0003] However, most macroporous adsorption devices have a drawback, that is, the fluidity of macroporous resin in the device is poor, which leads to a slow contact speed with the stock solution to be treated, and then affects the overall adsorption efficiency, making the adsorption process less efficient.

[0004] Therefore, aiming at the situation that the poor fluidity of macroporous resin in the device leads to a reduction in the adsorption efficiency of the liquid, a macroporous resin adsorption and desorption device can be designed. Through the gear transmission structure and the rotary stirring structure, while stirring the macroporous resin, the macroporous resin and the liquid are fully mixed, thereby improving the adsorption efficiency. Summary of the Utility Model

[0005] In order to overcome the problem that the poor fluidity of macroporous resin in the device leads to a reduction in the adsorption efficiency of the liquid.

[0006] The technical solution of the utility model is: a macroporous resin adsorption and desorption device, which includes feet, an adsorption box, a drainage frame, a water inlet pipe, a water outlet pipe, a coaxial reverse rotation assembly, a stirring structure and an adsorption assembly; there are four groups of feet and they are symmetrically and fixedly connected to the outer wall of the adsorption box on the left and right. The lower end of the adsorption box is fixedly connected with a funnel-shaped drainage frame, and the water outlet pipe is adapted to the water outlet of the drainage frame and is installed at the lower end of the water outlet. The water inlet pipe is installed on the upper left side of the adsorption box. The coaxial reverse rotation assembly is installed in the adsorption box and a gear transmission structure is arranged in the coaxial reverse rotation assembly. The stirring structure is fixedly connected to the outer walls of the forward rotating shaft and the reverse rotating shaft in the coaxial reverse rotation assembly. The adsorption assembly is installed in the adsorption box.

[0007] Preferably, the feet are the basic support part of the device, ensuring that the entire adsorption box can be stably placed on the ground and preventing shaking or tipping during operation. The adsorption box is used to accommodate macroporous resin and the solution to be treated. The drainage frame is located at the lower end of the adsorption box and is designed in a funnel shape for collecting and discharging the solution after adsorption treatment. The coaxial reverse rotation assembly realizes the synchronous but reverse rotation of the forward rotating shaft and the reverse rotating shaft through a gear transmission structure. This design helps to enhance the mixing effect of the solution in the adsorption box and improve the adsorption efficiency. The stirring structure is fixedly connected to the outer walls of the forward rotating shaft and the reverse rotating shaft in the coaxial reverse rotation assembly and rotates with the rotation of the rotating shaft. Its function is to stir the solution and resin in the adsorption box, enabling the two to come into full contact and react. The adsorption assembly provides a place for the contact and reaction between the resin and the solution, and these materials capture and enrich the target organic substances from the solution through physical adsorption.

[0008] Preferably, the coaxial reverse rotation assembly includes a rotating motor, a coupling, a connecting shaft, and a rotating support seat. The rotating motor is installed on the right side inside the adsorption box. The right end of the connecting shaft is equipped with a coupling and is connected to the output shaft of the rotating motor through the coupling. The rotating support seat is fixedly connected to the top inside the adsorption box. The rotating motor is the power source of the entire coaxial reverse rotation assembly, providing the necessary torque and rotational speed to drive the rotational movement of the entire assembly. The coupling is used to connect the output shaft of the rotating motor and the connecting shaft to ensure stable transmission between the two. The connecting shaft transmits the rotational action of the rotating motor to the first bevel gear. The rotating support seat provides stable support for the forward rotating shaft to ensure the stability of the forward rotating shaft during rotation.

[0009] Preferably, the coaxial reverse rotation assembly further includes a forward rotating shaft and a reverse rotating shaft. The upper end of the forward rotating shaft is rotatably connected inside the rotating support seat. The reverse rotating shaft is shorter than the forward rotating shaft and is sleeved on the outer wall of the forward rotating shaft. The forward rotating shaft and the reverse rotating shaft are the core components of the coaxial reverse rotation assembly and realize synchronous but reverse rotational movement through gear transmission. This design helps to enhance the stirring effect and improve the adsorption efficiency. Both of them are meshed and driven with the bevel gears on the connecting shaft through bevel gears.

[0010] Preferably, the coaxial reverse assembly further includes a first bevel gear, a second bevel gear, a third bevel gear, and a limit bracket; the first bevel gear is fixedly connected to the outer wall of the connecting shaft, the second bevel gear is fixedly connected to the outer wall of the forward rotating shaft, the third bevel gear is fixedly connected to the outer wall of the reverse rotating shaft, the first bevel gear is meshed with the second bevel gear, the first bevel gear is meshed with the third bevel gear, the upper end of the limit bracket is fixedly connected to the top inside the adsorption box, a limit groove adapted to the third bevel gear is provided inside the limit bracket, and the third bevel gear is rotatably connected to the corresponding limit groove. The first bevel gear, the second bevel gear, and the third bevel gear are used to achieve the transmission between two perpendicular intersecting shafts, that is, to transmit the torque and speed of the rotating motor to the forward rotating shaft and the reverse rotating shaft through the connecting shaft, and ensure that the two rotate synchronously but in opposite directions. The limit bracket is used to ensure the stability of the reverse rotating shaft during rotation.

[0011] Preferably, the stirring structure includes stirring blades; there are three stirring blades, which are respectively fixedly connected to the outer walls of the forward rotating shaft and the reverse rotating shaft. The three stirring blades are all distributed along the axial direction of the forward rotating shaft and the reverse rotating shaft. The centrifugal force generated by the rotation of the stirring blades fully stirs and mixes the liquid and the macroporous resin. Since the forward rotating shaft and the reverse rotating shaft rotate synchronously but in opposite directions, these stirring blades will also rotate in opposite directions, thereby enhancing the stirring effect.

[0012] Preferably, the adsorption assembly includes a first adsorption box and a second adsorption box; the first adsorption box and the second adsorption box are fixedly connected to the inner wall of the adsorption box in sequence from top to bottom. The stirring blades on the reverse rotating shaft are located inside the first adsorption box, and the stirring blades on the forward rotating shaft are located inside the second adsorption box. The first adsorption box and the second adsorption box are the main parts of the adsorption assembly. They are responsible for accommodating the liquid and macroporous resin to be processed, and adsorbing or separating specific components through their internal structures and materials. The two are fixedly connected to the inner wall of the adsorption box in sequence from top to bottom. This design enables the liquid to pass through the two adsorption boxes in sequence, thereby achieving a multi-stage adsorption effect.

[0013] Preferably, the adsorption assembly further includes water passing holes and feed pipes; water passing holes are opened at the lower ends of both the first adsorption box and the second adsorption box. There are two feed pipes, and both are installed at the left end of the adsorption box. The right ends of the two feed pipes extend to the inside of the adsorption box. The water passing holes are located at the lower ends of the first adsorption box and the second adsorption box, and are channels connecting the two adsorption boxes and allowing the liquid to flow through. Through the water passing holes, the liquid can flow from the first adsorption box into the second adsorption box to achieve a continuous adsorption process. The feed pipes are channels for introducing macroporous resin into the adsorption assembly, thereby providing the necessary raw materials for the adsorption process.

[0015] 1. Through the coordinated operation of the coaxial reverse assembly, the stirring structure, and the adsorption assembly, the forward rotating shaft and the reverse rotating shaft rotate synchronously but in opposite directions.

The feet 1 are the basic support part of the device, ensuring that the entire adsorption tank 2 can be stably placed on the ground and preventing shaking or tipping during operation. The adsorption tank 2 is used to accommodate macroporous resin and the solution to be treated. The drainage frame 3 is located at the lower end of the adsorption tank 2 and is designed in a funnel shape to collect and discharge the solution after adsorption treatment. The coaxial reverse rotation assembly realizes the synchronous but reverse rotation of the forward rotating shaft 605 and the reverse rotating shaft 606 through the gear transmission structure. This design helps to enhance the mixing effect of the solution in the adsorption tank 2 and improve the adsorption efficiency. The stirring structure is fixedly connected to the outer walls of the forward rotating shaft 605 and the reverse rotating shaft 606 in the coaxial reverse rotation assembly and rotates with the rotation of the rotating shaft.

The rotary motor 601 is the power source of the entire coaxial reverse rotation assembly, providing the necessary torque and rotational speed to drive the rotational movement of the entire assembly. The coupling 602 is used to connect the output shaft of the rotary motor 601 and the connecting shaft 603 to ensure stable transmission between the two. The connecting shaft 603 transmits the rotational action of the rotary motor 601 to the first bevel gear 607. The rotary support base 604 provides stable support for the forward rotating shaft 605 to ensure the stability of the forward rotating shaft 605 during rotation. The forward rotating shaft 605 and the reverse rotating shaft 606 are the core components of the coaxial reverse rotation assembly, achieving synchronous but reverse rotational movement through gear transmission. This design helps to enhance the stirring effect and improve the adsorption efficiency. Both of them are meshed and transmitted with the bevel gears on the connecting shaft 603 through bevel gears. The first bevel gear 607, the second bevel gear 608, and the third bevel gear 609 are used to achieve transmission between two perpendicular intersecting shafts, that is, transmitting the torque and rotational speed of the rotary motor 601 to the forward rotating shaft 605 and the reverse rotating shaft 606 through the connecting shaft 603, and ensuring that the two achieve synchronous but reverse rotation. The limit bracket 610 is used to ensure the stability of the reverse rotating shaft 606 during rotation.

[0027] Please refer to Figures 5-6, in this embodiment, the stirring structure includes stirring blades 7; there are three stirring blades 7 which are respectively fixedly connected to the outer walls of the forward rotating shaft 605 and the reverse rotating shaft 606. The three stirring blades 7 are all distributed along the axial directions of the forward rotating shaft 605 and the reverse rotating shaft 606. The centrifugal force generated by the rotation of the stirring blades 7 fully stirs and mixes the liquid and the macroporous resin. Since the forward rotating shaft 605 and the reverse rotating shaft 606 rotate synchronously but in opposite directions, these stirring blades 7 will also rotate in opposite directions, thereby enhancing the stirring effect. The adsorption assembly includes a first adsorption box 801 and a second adsorption box 802; the first adsorption box 801 and the second adsorption box 802 are fixedly connected to the inner wall of the adsorption box 2 in sequence from top to bottom. The stirring blades 7 on the reverse rotating shaft 606 are located in the first adsorption box 801, and the stirring blades 7 on the forward rotating shaft 605 are located in the second adsorption box 802. The adsorption assembly further includes water passing holes 803 and feed pipes 804; water passing holes 803 are opened at the lower ends of both the first adsorption box 801 and the second adsorption box 802. There are two feed pipes 804 and both are installed at the left end of the adsorption box 2. The right ends of the two feed pipes 804 extend rightward into the adsorption box 2. The first adsorption box 801 and the second adsorption box 802 are the main parts of the adsorption assembly. They are responsible for containing the liquid and macroporous resin to be processed and adsorbing or separating specific components through their internal structures and materials. The two are fixedly connected to the inner wall of the adsorption box 2 in sequence from top to bottom. This design enables the liquid to pass through the two adsorption boxes 2 in sequence, thereby achieving a multi-stage adsorption effect. The water passing holes 803 are located at the lower ends of the first adsorption box 801 and the second adsorption box 802 and are channels connecting the two adsorption boxes 2 and allowing the liquid to flow through. Through the water passing holes 803, the liquid can flow from the first adsorption box 801 into the second adsorption box 802 to achieve a continuous adsorption process. The feed pipes 804 are channels for introducing macroporous resin into the adsorption assembly, thereby providing the necessary raw materials for the adsorption process.

[0028] In the operation process, the staff first accurately send the macroporous resin into the corresponding adsorption boxes through the two feed pipes 804. Subsequently, the liquid to be processed is injected into the first adsorption box 801 by using the water inlet pipe 4. The rotary motor 601 is started. The motor drives the connecting shaft 603 to rotate, and with the precise meshing of the gears, drives the forward rotating shaft 605 and the reverse rotating shaft 606 to rotate synchronously in opposite directions. At this time, under the action of gravity and rotational force, the liquid smoothly passes through the water passing holes 803 at the bottom of the first adsorption box 801 and flows into the second adsorption box 802;

[0029] During the adsorption process, the stirring fan blades 7 in the first adsorption box 801 and the second adsorption box 802 rotate in opposite directions along their respective rotating shafts, efficiently and evenly stirring the liquid and the macroporous resin. This reverse rotation stirring method effectively promotes the full contact between the liquid and the macroporous resin, significantly improving the adsorption efficiency. Finally, the liquid that has been fully adsorbed flows through the water passing holes 803 of the second adsorption box 802 into the drainage frame 3 under the action of gravity, and is finally smoothly discharged through the water outlet pipe 5, completing the entire adsorption process.

[0030] Through the above steps, through the coordinated operation of the coaxial reverse rotation assembly, the stirring structure, and the adsorption assembly, the synchronous but reverse rotation of the forward rotating shaft 605 and the reverse rotating shaft 606 is achieved. This not only promotes the full mixing and flow of the liquid in the adsorption box 2, but also enables the macroporous resin in the first adsorption box 801 and the second adsorption box 802 to effectively adsorb the target components, thereby enhancing the adsorption effect and solving the problem that the poor fluidity of the macroporous resin in the device leads to a decrease in the adsorption efficiency of the liquid.

[0031] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art.
