Abstract
Description
A multi-stage ultrafiltration impurity removal device for glutathione catalyst solution Technical Field
[0001] This utility model relates to the field of ultrafiltration impurity removal technology, and more specifically, to a multi-stage ultrafiltration impurity removal device using glutathione catalyst. Background Technology
[0002] Glutathione, as an important bioactive molecule, is widely used in pharmaceuticals, food, and cosmetics. Efficient purification of the catalyst solution during its production is crucial for ensuring product purity and yield. Traditional catalyst solution purification processes often rely on single filtration or centrifugation techniques, which have significant limitations: for example, conventional filters can only intercept large particles, while their effectiveness in retaining fine suspended solids is poor, requiring repeated filtration and resulting in low efficiency; simultaneously, the catalyst solution adsorbed in the filter residue is difficult to fully recover, leading to resource waste; furthermore, static filtration devices lack dynamic compression capabilities, making the filter pores prone to clogging and requiring frequent shutdowns for cleaning, severely impacting continuous production.
[0003] In recent years, although some improved filtration equipment has introduced multi-stage filters or vibration-assisted structures, there are still technical bottlenecks. For example, although multi-stage filters can trap impurities in stages, the accumulation of filter residue will still lead to catalytic liquid residue, and there is a lack of targeted pressure filtration design. While vibration-assisted devices can reduce clogging, they are prone to splashing of catalytic liquid or secondary pollution, and it is difficult to achieve precise control of pressure filtration force. Therefore, in order to address the above technical problems, a multi-stage ultrafiltration impurity removal device for glutathione catalytic liquid is proposed here. Summary of the Invention
[0004] The purpose of this invention is to provide a multi-stage ultrafiltration impurity removal device for glutathione catalyst solution. Through two-stage filtration of filter screen and filter plate, combined with dynamic pressure filtration of pressure plate, impurities are classified and intercepted and the catalyst solution is efficiently recovered. In addition, the coordinated control of the rebound mechanism and drive motor ensures that the pressure filtration action is reversible and cyclical, which significantly improves the ultrafiltration efficiency and the sustainable operation of the device. At the same time, the inclined plate guide design further optimizes the discharge stability.
[0005] This utility model is achieved through the following technical solution:

[0017] The technical solution of this utility model has at least the following beneficial effects:
[0018] This multi-stage ultrafiltration equipment for glutathione catalyst solution significantly improves the purity of the catalyst solution through dual filtration: large particles are intercepted by the filter screen, while fine suspended matter is retained by the micropores of the filter plate. Simultaneously, the dynamic downward pressure of the pressure plate squeezes the filter residue, allowing residual catalyst solution to fully seep out, greatly reducing resource waste. The automatic filtration cycle, achieved through a drive motor and elastic reset design, prevents filter pore clogging, reduces the frequency of manual cleaning, and ensures continuous production. Furthermore, the inclined plate flow guiding structure further optimizes liquid collection efficiency, comprehensively solving problems such as low filtration efficiency, high levels of catalyst solution residue, and easy clogging in traditional processes. It improves glutathione production efficiency while also ensuring ease of operation and economy. Attached Figure Description

[0027] A cone-shaped container 4 is fixedly connected to the upper end of the inlet pipe 3. The cone-shaped container 4 is designed to facilitate the concentrated delivery of the catalyst liquid and avoid liquid splashing.
[0028] The filter plate 6 has multiple arrays of tiny micropores on its exterior. These micropores are evenly distributed to enhance the fineness and efficiency of secondary filtration. Two sets of symmetrically arranged fixing rods 8 are fixedly connected to the inner side of the main body 1 of the device. The fixing rods 8 are close to the two ends of the upper surface of the filter plate 6. The pressure plate 7 is rotatably connected to the outside of the fixing rods 8. The pressure plate 7 can rotate under the limitation of the fixing rods 8.
[0029] The rebound mechanism includes an arc-shaped cylinder 9, an arc-shaped rod 10, a sliding plate 11, and a tension spring 12. The arc-shaped cylinder 9 is fixedly connected to the outside of the two inner side walls of the main body 1 of the equipment.

[0030] The filter press mechanism includes a rotating shaft 14 and a connecting rope 15. The rotating shaft 14 is rotatably connected to the inner side of the main body 1 of the equipment and is installed on the lower side of the filter plate 6.

[0034] The working principle of the multi-stage ultrafiltration impurity removal device for glutathione catalyst solution based on the embodiment is as follows: First, the glutathione catalyst solution to be treated is introduced into the device through the cone 4. As it flows downward along the inlet pipe 3, the filter screen 5 fixed at the bottom of the inlet pipe 3 completes the initial filtration, intercepting larger impurities and achieving primary impurity removal. The catalyst solution containing fine impurities after the initial filtration then falls into the device body 1 and concentrates in the area between the two sets of symmetrically inclined pressure plates 7 and filter plates 6. After the catalyst solution contacts the filter plate 6, it undergoes secondary filtration through the array of fine micropores on its surface, further separating the fine impurities. During this process, in order to reduce the loss of catalyst solution remaining on the surface of the filter plate 6, the drive motor 13 is started to drive the rotating shaft 14 to rotate. The connecting rope 15 pulls the end of the pressure plate 7 downward to rotate the two sets of pressure plates 7 and filter plates 6. Plate 7 applies pressure to the impurity layer on filter plate 6. This dynamic pressure filtration action forces the catalytic liquid adsorbed in the impurities to seep out from the micropores, significantly improving the catalytic liquid recovery rate. At the same time, during the downward pressing of plate 7, the arc-shaped rod 10 connected to its upper part drives the slide plate 11 to slide along the inner side of the arc-shaped cylinder 9, stretching the tension spring 12 to accumulate elastic potential energy. When the pressure filtration is completed, the drive motor 13 reverses to release the connecting rope 15. The restoring force of the tension spring 12 drives the slide plate 11 to slide in the opposite direction, pulling plate 7 back to its initial tilted state through the arc-shaped rod 10, providing operating space for the next round of filtration. The catalytic liquid, after multi-stage treatment, finally flows into the bottom of the main body 1 of the equipment, is guided to the outlet 16 by the symmetrically arranged inclined plates 17, and is discharged in a concentrated manner through the outlet nozzle 18. The inclined design of the inclined plates 17 avoids liquid residue and ensures efficient discharge.
