Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to an integrated D-ribose ultrafiltration membrane device. Background Technology

[0002] Purification is a crucial step in the production of D-ribose. Since D-ribose is typically present in low concentrations in the fermentation broth and is mixed with other impurities, it needs to be separated using effective purification techniques.

[0003] A search revealed a utility model patent with Chinese patent publication number CN213060396U, which discloses a novel antibacterial ultrafiltration membrane filtration device. The device has three return pipes on one side of its main body, and three discharge pipes on its lower end. Each of the three return pipes has an auxiliary pipe at one end, and an output end is installed at one end of each auxiliary pipe. The output end is installed on one side of the main liquid conveying pipe.

[0004] When using the above-mentioned device, multiple ultrafiltration membrane devices are usually put into use at the same time to improve the processing efficiency. However, as the usage time increases, the modules need to be replaced, which requires shutdown and consumes a long time for operation, making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide an integrated D-ribose ultrafiltration membrane device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated D-ribose ultrafiltration membrane device, including a mounting frame, inside which two sets of vertically arranged filter cartridges are fixedly installed, and each set of filter cartridges consists of one or more individual units. A vertically arranged support plate is fixedly connected to the bottom of the mounting frame, and an inlet pipe and an outlet pipe are rotatably connected inside the support plate. The ends of the two sets of filter cartridges are fixedly connected to the same inlet pipe group, and the outside of the two sets of filter cartridges is fixedly connected to the same outlet pipe group. A reversing component is installed on both the inlet pipe and the two inlet pipe groups and the outlet pipe and the two outlet pipe groups. A rubber joint is provided on the outer wall of one end of the inlet pipe, which can enter the opening of the inlet pipe group. A horizontally arranged rotary joint is installed on one end of the inlet pipe.

[0007] As a further preferred embodiment of this technical solution, a vertically arranged hydraulic cylinder is fixedly installed on the outside of the support plate, and a vertically arranged rack is fixedly connected to the output end of the hydraulic cylinder. A toothed ring is coaxially fixed on the outside of both the second water inlet pipe and the second water outlet pipe, and the rack meshes with the two toothed rings.

[0008] This device can quickly replace another set of filter elements, thus ensuring seamless operation and effectively preventing any adverse impact on work efficiency during module replacement. Activating the hydraulic cylinder outside the support plate causes the output end of the hydraulic cylinder to move the rack downwards. The rack meshes with two toothed rings, which in turn rotate the inlet pipe and outlet pipe, respectively. The ends of these two pipes then connect with another inlet pipe assembly and outlet pipe assembly, respectively. Because the rubber joint can deform, the connection process of the inlet pipe or outlet pipe can proceed smoothly, and under pressure, the connection is also ensured to be tighter.

[0009] As a further preferred embodiment of this technical solution, a connecting ring is coaxially fixed to the outer circumference of the water inlet pipe assembly, a tensioning ring adapted to the connecting ring is coaxially fixed to the outer circumference of the two water inlet pipes, and an extension ring is coaxially fixed to the outer circumference of the two water inlet pipes.

[0010] As a further preferred embodiment of this technical solution, each of the plurality of filter cartridges is equipped with a filter assembly, the filter assembly including a support mesh cylinder that is slidably inserted into the filter cartridge.

[0011] As a further preferred embodiment of this technical solution, an ultrafiltration membrane layer is provided inside the supporting mesh cylinder, an activated carbon layer is provided inside the ultrafiltration membrane layer, and a filter screen is provided inside the activated carbon layer. The filter screen is slidably sleeved outside the liquid inlet inside the filter cylinder.

[0012] As a further preferred embodiment of this technical solution, four reinforcing plates are fixedly connected to the bottom outer wall of the mounting frame. The second water inlet pipe and the second water outlet pipe are rotatably connected inside two of the reinforcing plates, and the other two reinforcing plates are fixedly sleeved on the outside of the ends of the two water outlet pipe groups.

[0013] As a further preferred embodiment of this technical solution, rounded corners are provided at the inner circumference edge of one end of each of the two water inlet pipe assemblies.

[0014] This invention provides an integrated D-ribose ultrafiltration membrane device, which has the following beneficial effects:

[0015] This invention, by setting a reversing component, allows the device to quickly replace another set of filter elements, thereby ensuring seamless operation and effectively preventing any adverse impact on work efficiency during module replacement. Activating the hydraulic cylinder outside the support plate causes the output end of the hydraulic cylinder to move the rack downwards. The rack, through meshing, drives two toothed rings to rotate. These two toothed rings respectively rotate the second inlet pipe and the second outlet pipe, causing their ends to connect with another inlet pipe group and outlet pipe group, respectively. Because the rubber joint can deform, the connection process of the second inlet pipe or the second outlet pipe can proceed smoothly, and under pressure, a tighter connection is also ensured.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the integrated D-ribose ultrafiltration membrane device includes a mounting frame 1. Two sets of vertically arranged filter cartridges 2 are fixedly installed inside the mounting frame 1, and each set of filter cartridges 2 consists of more than one individual unit. A vertically arranged support plate 5 is fixedly connected to the bottom of the mounting frame 1. A second inlet pipe 6 and a second outlet pipe 7 are rotatably connected inside the support plate 5. The ends of the two sets of filter cartridges 2 are fixedly inserted with the same inlet pipe group 3. The outside of the two sets of filter cartridges 2 is fixedly inserted with the same outlet pipe group 4. A reversing component 9 is installed on the inlet pipe 6 and the two inlet pipe groups 3, and on the outlet pipe 7 and the two outlet pipe groups 4. The reversing component 9 includes a rubber joint 905 provided on the outer wall of one end of the inlet pipe 6. The rubber joint 905 can enter the opening of the inlet pipe group 3. A horizontally arranged rotary joint 901 is installed on one end of the inlet pipe 6.

[0024] A vertically arranged hydraulic cylinder 903 is fixedly installed on the outside of the support plate 5. A vertically arranged rack 904 is fixedly connected to the output end of the hydraulic cylinder 903. A toothed ring 902 is coaxially fixed on the outside of the water inlet pipe 6 and the water outlet pipe 7. The rack 904 meshes with the two toothed rings 902.

[0025] After running for a period of time, the hydraulic cylinder 903 outside the support plate 5 is started. The output end of the hydraulic cylinder 903 drives the rack 904 to move downward. The rack 904 drives the two toothed rings 902 to rotate through meshing. The two toothed rings 902 drive the inlet pipe 6 and the outlet pipe 7 to flip respectively. Then, the ends of the two will be connected to another inlet pipe group 3 and outlet pipe group 4 respectively. Since the rubber joint 905 can deform, it can ensure that the connection process of the inlet pipe 6 or the outlet pipe 7 can be carried out smoothly. Under the action of pressure, it can also ensure a tighter connection.

[0026] like Figure 3 As shown, a connecting ring 906 is coaxially fixed to the outer circumference of the water inlet pipe assembly 3, and a tensioning ring 908 adapted to the connecting ring 906 is coaxially fixed to the outer circumference of the second water inlet pipe 6. An extension ring 907 is coaxially fixed to the outer circumference of the second water inlet pipe 6. If the seal is not tight enough, pull the tensioning ring 908 toward the connecting ring 906, and then rotate the tensioning ring 908 to connect with the connecting ring 906. Then the tensioning ring 908 and the extension ring 907 abut against each other. The tensioning ring 908 can drive the second water inlet pipe 6 to squeeze toward the water inlet pipe assembly 3 through the extension ring 907, which can further increase the sealing performance of the two.

[0027] like Figure 1 and Figure 4 As shown, each of the several filter cylinders 2 has a filter assembly 8 installed inside it. The filter assembly 8 includes a support mesh cylinder 804 that is slidably inserted into the filter cylinder 2.

[0028] An ultrafiltration membrane layer 803 is provided inside the support cylinder 804, an activated carbon layer 802 is provided inside the ultrafiltration membrane layer 803, and a filter screen 801 is provided inside the activated carbon layer 802. The filter screen 801 is slidably sleeved outside the liquid inlet inside the filter cylinder 2.

[0029] The raw solution enters the inlet pipe group 3 through the second inlet pipe 6, and then enters the filter screen 801 of a row of multiple filter cylinders 2. After preliminary filtration by the filter screen 801, it is filtered by the activated carbon layer 802, and finally filtered by the ultrafiltration membrane layer 803 before passing through the holes of the support mesh cylinder 804 into the filter cylinder 2. It then enters a water outlet pipe group 4 and is finally conducted to the outside through the second water outlet pipe 7. Finally, the end cap of the old filter cylinder 2 is opened, and then the filter assembly 8 is pulled, and the filter assembly 8 can be quickly pulled out, making disassembly and assembly convenient.

[0030] like Figure 1 and Figure 2As shown, four reinforcing plates are fixedly connected to the bottom outer wall of the mounting frame 1. The second water inlet pipe 6 and the second water outlet pipe 7 are rotatably connected inside two of the reinforcing plates, and the other two reinforcing plates are fixedly sleeved on the outside of the ends of the two water outlet pipe groups 4. This helps to reinforce the state of the second water inlet pipe 6, the second water outlet pipe 7 and the two water outlet pipe groups 4, so that they will not easily deform when subjected to force.

[0031] like Figure 3 As shown, rounded corners are provided at the inner circumference edge of one end of both water inlet pipe groups 3, which reduces the obstruction encountered during the docking process between water inlet pipe group 3 and water inlet pipe 7.

[0032] This utility model provides an integrated D-ribose ultrafiltration membrane device, the specific working principle of which is as follows:

[0033] When the device is working, the raw liquid enters the inlet pipe group 3 through inlet pipe 2 6, and then enters the filter screens 801 of multiple filter cylinders 2. After preliminary filtration by filter screens 801, it is filtered by activated carbon layer 802, and finally filtered by ultrafiltration membrane layer 803 before passing through the holes of support screen cylinder 804 into filter cylinder 2. It then enters a single outlet pipe group 4, and finally is conducted to the outside through outlet pipe 2 7. After running for a period of time, the hydraulic cylinder 903 outside the support plate 5 is activated. The output end of hydraulic cylinder 903 drives rack 904 to move downward. Rack 904 drives two gear rings 902 to rotate through meshing. The two gear rings 902 respectively drive inlet pipe 2 6 and outlet pipe 2 7 to rotate, so that their ends will respectively engage with the other... A water inlet pipe assembly 3 and a water outlet pipe assembly 4 are connected. Because the rubber joint 905 can deform, the connection process of the second water inlet pipe 6 or the second water outlet pipe 7 can be carried out smoothly. Under pressure, the connection can also be made tighter. If the seal is not tight enough, pull the tension ring 908 towards the connecting ring 906, and then rotate the tension ring 908 to connect with the connecting ring 906. Then the tension ring 908 and the extension ring 907 abut against each other. The tension ring 908 can drive the second water inlet pipe 6 to squeeze towards the water inlet pipe assembly 3 through the extension ring 907, which can further increase the sealing of the two. Finally, open the old filter cylinder 2 end cover, and then apply a pulling force to the filter assembly 8. The filter assembly 8 can be quickly pulled out, making disassembly and assembly convenient enough.
