Description

Technical Field

[0001] This utility model relates to the technical field of lactulose oral solution production equipment, and in particular to a precipitation and filtration device for lactulose oral solution production. Background Technology

[0002] Lactulose Oral Solution is a clear, brownish-yellow, viscous liquid. It is used to treat hyperammonemia and diseases caused by elevated blood ammonia levels; it is also used to treat chronic functional constipation.

[0003] In the production process of lactulose oral solution, it is necessary to clean the internal impurities. However, most methods currently rely on simple filtration, which results in poor impurity removal and inadequate separation of particulate matter from the solution, leading to low production efficiency.

[0004] Therefore, a lactulose oral solution production device using filtration and precipitation is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To overcome the shortcomings of existing technologies, a precipitation and filtration device for lactulose oral solution production is proposed. This device addresses the problem that current lactulose oral solution production processes often rely on single-value filtration to remove internal impurities, resulting in poor impurity removal, inadequate separation of particulate matter from the solution, and low production efficiency.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: This utility model proposes a precipitation and filtration device for producing lactulose oral solution, comprising a filter box and a precipitation box stacked on top of each other.

[0009] The filter box is equipped with a ring-shaped filter screen inside, and the liquid inlet at the top of the filter box is located inside the filter screen. The bottom of the filter box has a drop outlet that penetrates the upper end of the sedimentation tank. The bottom of the filter screen has a discharge outlet, and a first solenoid valve is installed inside the discharge outlet.

[0010] The bottom of the sedimentation tank is provided with a through outlet, and the other side of the sedimentation tank is provided with several side outlets from top to bottom, and a second solenoid valve is installed inside the outlet and the side outlets.

[0011] Furthermore, an inclined conduit is connected to the bottom of the outlet, penetrating the side of the sedimentation tank.

[0012] Furthermore, a rotating shaft is rotatably installed inside the filter box, and a motor is installed on the top of the filter box and connected to the rotating shaft. A force-bearing plate is connected to the outside of the rotating shaft through a connecting rod, and a scraper is provided on the outside of the force-bearing plate to contact the filter screen.

[0013] Furthermore, a main flow pipe is connected to the outer side of each of the side outlets.

[0014] Furthermore, the bottom surface inside the sedimentation tank is inclined towards the liquid outlet.

[0015] Furthermore, the bottom of the sedimentation tank is provided with a support block, and a controller and an observation window are installed on the outside of the sedimentation tank.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] 1. In this utility model, the raw material is fed into the filter screen inside the filter box through the liquid inlet. Under the action of the filter screen, it is filtered and then enters the sedimentation tank through the drop outlet, where it settles naturally. The side outlets are opened one by one to drain the liquid from top to bottom, avoiding the discharge of the bottom sediment. This makes the lactulose oral solution filter better, reduces internal impurities, and improves the quality.

[0019] 2. In this utility model, the rotating shaft driven by the motor causes the scraper on the side to rotate and clean the filter screen, thus avoiding impurities clogging the filter screen and resulting in poor filtration effect. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a precipitation and filtration device for producing lactulose oral solution, including a filter box 2 and a sedimentation box 1 stacked on top of each other, which allows for two steps of filtration and precipitation of lactulose oral solution, resulting in better product quality. The bottom of the sedimentation box 1 is equipped with a support block 8 to raise the bottom and facilitate the discharge of material from the bottom. A controller 3 and an observation window 4 are installed on the outside of the sedimentation box 1. The controller 3, which is purchased externally, facilitates the operation of the electrical components in the device, making it more convenient for the staff to operate. The observation window 4 facilitates the observation of the water level inside the sedimentation box 2, which is convenient for the liquid discharge work.

[0027] The filter box 2 has a ring-shaped filter screen 11 inside, which is designed to perform filtration in a cylindrical shape. The inlet 5 at the top of the filter box 2 is located inside the filter screen 11, allowing lactulose oral solution to be introduced into the filter screen 11 for filtration. The bottom of the filter box 2 has a drop outlet 10 that penetrates the upper end of the sedimentation box 1. A solenoid valve can be installed inside the drop outlet 10 to facilitate the lowering operation by the operator, allowing the upper filter box to continue filtration during sedimentation. The bottom of the filter screen 11 has a discharge outlet 12 to discharge the filtered impurities. The bottom of the discharge outlet 12 is connected to an inclined conduit 14 that penetrates the side of the sedimentation box 1, allowing the device to discharge and collect the impurities, avoiding subsequent cleaning and improving work efficiency. A first solenoid valve 13 is installed inside the discharge outlet 12, which can be used for the first... The solenoid valve 13 prevents impurities from being discharged during filtration, resulting in better working performance. The bottom of the sedimentation tank 1 has a through outlet 9 to discharge the remaining liquid after sedimentation. The bottom surface of the sedimentation tank 1 is inclined towards the outlet 9 to reduce accumulation on one side, resulting in better discharge. On the other side of the sedimentation tank 1, there are several side outlets 19 arranged from top to bottom. The side outlets 19 can be opened sequentially from top to bottom to allow for slow discharge, avoiding excessively fast discharge rate from affecting the sedimentation. Each side outlet 19 is connected to a main pipe 7 to facilitate the centralized collection of the discharged liquid. Both the outlet 9 and the side outlet 19 are equipped with a second solenoid valve 110 to facilitate the operation of the discharged liquid by the operator.

[0028] Inside the filter box 2, a rotating shaft 15 is rotatably installed. A motor 6 is installed on the top of the filter box and connected to the rotating shaft 15. A force plate 17 is connected to the outside of the rotating shaft 15 through a connecting rod 16. A scraper 18 is provided on the outside of the force plate 17 and contacts the filter screen 11. When the motor 6 drives the rotating shaft 15, the connecting rod 16 pulls the force plate 17, causing the scraper 18 to scrape the filter screen 11, thereby preventing impurities from clogging the filter screen 11 and resulting in poor filtration.

[0029] Working principle: In use, first connect the motor 6, the first solenoid valve 13, the second solenoid valve 110 to the controller 3, and connect to an external power supply. Then, the lactulose oral solution is fed into the filter screen 11 through the inlet 5. The motor 6 drives the rotating shaft 15 to scrape the side scraper 18, which avoids clogging during the scraping process. The filtered solution enters the sedimentation tank 1 through the drop outlet 10 for sedimentation treatment. During sedimentation, filtration is stopped and the first solenoid valve 13 is opened to discharge impurities. After observing the internal sedimentation through the observation window 4, the side outlet 19 can be opened in sequence to drain the liquid. After the settled solution at the top is discharged, the entire contents are discharged through the outlet 9, thus completing the work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
