Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration technology, specifically to a device for refining viscous polymer liquid. Background Technology
[0002] In the process of drug development, filtration is an important process that needs to be studied in the field of formulation technology. At present, laboratory filtration is mainly carried out by suction filtration, peristaltic pump connected to small stainless steel filter or compressed air through filter element in large filter. However, these common filtration methods are not suitable for filtering viscous liquids.
[0003] Existing patent application CN202321409886.6 discloses a laboratory viscous liquid filtration device for filtering liquids, particularly viscous liquids. The filtration device includes a storage tank and a filter connected via an adapter and a valve. The upper end of the filter can be customized with a filter of varying lengths and equipped with an exhaust valve, depending on specific requirements. The upper end of the storage tank is connected to a valve via a tee connector, and the valve is connected to a gas storage tank via a pipeline. The gas storage tank is equipped with a gas supply switch, a gas valve, and a pressure gauge. The other end of the gas storage tank is connected to compressed air. This invention enables the filtration of viscous liquids, avoiding the loss of viscous liquids associated with using large filters and the low filtration efficiency of peristaltic pumps, thus improving the filtration efficiency of viscous liquids.
[0004] However, after the aforementioned patented equipment is used, there will be viscous liquid residue on the inner wall of the filter chamber, which needs to be cleaned manually. Otherwise, it will affect the filtration quality of the viscous liquid in the future, and manual cleaning will increase the labor intensity of the operators. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for refining viscous polymer liquid. By activating the heating plate inside the spiral auger, the liquid can be heated to improve its fluidity and ensure that it can flow quickly toward the filter plate. In conjunction with the starting motor, the spiral auger can be driven to rotate, which not only facilitates the flow of the liquid toward the filter plate but also cleans the liquid adhering to the inner wall of the first cylinder.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A device for refining viscous polymer liquid includes a first cylinder and a second cylinder. The second cylinder is slidably disposed inside the first cylinder. The interior of the first cylinder and the bottom of the second cylinder form a temporary storage chamber. A filter plate is disposed at the bottom of the second cylinder. A spiral auger capable of contacting the inner wall of the second cylinder is disposed inside the second cylinder. A motor for driving the spiral auger is disposed at the top of the second cylinder. A lifting device is disposed at the upper outer edge of the first cylinder and is connected to the top of the second cylinder. An inlet pipe and a feed pipe are disposed on the side wall of the top of the second cylinder. The spiral auger has a cavity inside and a heating element is disposed inside the cavity.
[0008] Preferably, the feed pipe is equipped with a first valve, the feed pipe can be connected to an external liquid storage tank through a hose, and a gas compression device is provided on one side of the liquid storage tank, the gas compression device is connected to the liquid storage tank through a pipe.
[0009] Preferably, a second valve is provided on the inlet pipe, and the inlet pipe can be connected to an external cleaning agent storage tank through a hose. A pump body is provided between the cleaning agent storage tank and the inlet pipe, and the pump body can deliver the cleaning agent inside the cleaning agent storage tank to the inside of the second cylinder.
[0010] Preferably, the lifting device includes an electric actuator, which is mounted on the outer edge of the top of the first cylinder via a mounting ring. A connecting plate is installed at the power output end of the electric actuator, and the connecting plate can be connected to the top of the first cylinder.
[0011] Preferably, a pressure relief valve is provided on one side of the first cylinder located at the upper end of the temporary storage chamber, and a third valve is provided on the pressure relief valve.

[0013] Preferably, the first cylinder is provided with an observation window made of borosilicate glass, and the bottom of the second cylinder is equipped with an annular scraper that can abut against the inner wall of the first cylinder.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model has a simple structure. By activating the heating element inside the spiral auger, the liquid material can be heated, improving its fluidity and ensuring that it can flow quickly toward the filter plate. In conjunction with the starting motor, the spiral auger can be driven to rotate, which not only facilitates the flow of the liquid material toward the filter plate but also cleans the liquid material adhering to the inner wall of the first cylinder.
[0016] 2. After the liquid inside the storage tank in this device is completely filtered, the gas compression device continues to supply high-pressure gas to the first cylinder and the temporary storage chamber. By closing the third valve on the pressure relief valve and opening the fourth valve at the top of the discharge pipe, the filtered liquid inside the temporary storage chamber can be quickly discharged from the discharge pipe. At this time, in order to avoid a large amount of liquid adhering to the inner wall of the temporary storage chamber, the lifting device is activated. The lifting device drives the second cylinder to slide to the bottom of the first cylinder. Since the outer wall of the second cylinder is adapted to the inner wall of the first cylinder, when the second cylinder descends inside the first cylinder, the bottom outer edge of the second cylinder can scrape off the liquid adhering to the inner wall of the temporary storage chamber, making it easier for it to be discharged from the discharge pipe.
[0017] 3. This device injects cleaning agent into the second cylinder through the inlet pipe. The motor drives the spiral auger to continue rotating, which can clean the inner wall of the second cylinder. At the same time, when the liquid flows to the filter plate and enters the gap between the bottom of the first and second cylinders, it can clean the filter plate and the temporary storage chamber, avoiding manual cleaning and reducing the labor intensity of operators.
[0018] 4. The connecting plate of this device is detachably connected to the top of the second cylinder, which facilitates the removal of the second cylinder from the inside of the first cylinder for maintenance or replacement of the filter plate at the bottom of the second cylinder, ensuring the practicality of this device.
[0019] 5. The observation window on the first cylinder of this device allows operators to easily observe whether the temporary storage chamber and filter plate have been completely cleaned during cleaning, ensuring the filtration quality of the subsequent liquid. The annular scraper installed at the bottom of the second cylinder can abut against the inner wall of the first cylinder, making it easy to scrape off all the liquid adhering to the inside of the temporary storage chamber, thus improving the cleaning effect of the device on the adhering liquid.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] A device for refining viscous polymer liquid, the structure of which is as follows: Figures 1-4 As shown, the system includes a first cylinder 1 and a second cylinder 2. The second cylinder 2 is slidably disposed inside the first cylinder 1. A temporary storage chamber 13 is formed between the interior of the first cylinder 1 and the bottom of the second cylinder 2. A filter plate 10 is disposed at the bottom of the second cylinder 2. A spiral auger 7, capable of contacting the inner wall of the second cylinder 2, is disposed inside the second cylinder 2. A motor 6, for driving the spiral auger 7, is disposed at the top of the second cylinder 2. A lifting device is disposed on the upper outer edge of the first cylinder 1, and the lifting device is connected to the top of the second cylinder 2. An inlet pipe 9 and a feed pipe 8 are disposed on the side wall of the top of the second cylinder 2. The spiral auger 7 has a cavity inside, and a heating element 11 is disposed inside the cavity of the spiral auger 7. A first valve is disposed on the feed pipe 8, and the feed pipe 8 can be connected to an external storage tank through a hose. A gas compression device is disposed on one side of the storage tank, and the gas compression device is connected to the storage tank through a pipe. The high-pressure gas in the gas compression device can drive the viscous polymer liquid inside the storage tank into the second cylinder 2. A pressure relief valve 12 is provided on one side of the first cylinder 1 located at the upper end of the temporary storage bin 13, and a third valve is provided on the pressure relief valve 12. A support leg 15 is provided at the outer edge of the bottom end of the first cylinder 1, and a discharge pipe 14 is provided at the bottom of the first cylinder 1, and a fourth valve is provided on the discharge pipe 14.
[0028] When it is necessary to refine viscous polymer liquid, high-pressure gas is injected into the storage pipe by starting the gas compression device. At this time, the first valve on the feed pipe 8 is opened, ensuring that the liquid inside the storage tank enters the second cylinder 2 through the feed pipe 8. The liquid entering the second cylinder 2 flows towards the filter plate 10 along the spiral auger 7 under its own weight. At this time, the heating plate 11 inside the spiral auger 7 is activated to heat the liquid, improve the fluidity of the liquid, ensure that the liquid can flow quickly towards the filter plate 10, and increase the speed of the liquid passing through the filter plate 10. When a lot of liquid accumulates on the surface of the filter plate 10, the pressure inside the second cylinder 2 will increase due to the liquid continuously being delivered into the second cylinder 2, which will quickly force the liquid to pass through the filter plate 10 for effective filtration. The liquid after passing through the filter plate 10 continuously enters the temporary storage chamber 13 inside the second cylinder 2, and the pressure inside the temporary storage chamber 13 will continue to increase. The air pressure inside the temporary storage chamber 13 can be discharged through the pressure relief valve 12.
[0029] Meanwhile, to prevent some liquid from adhering to the inner wall of the first cylinder 1, the starting motor 6 can drive the spiral auger 7 to rotate, which not only facilitates the flow of liquid towards the filter plate 10, but also cleans the liquid adhering to the inner wall of the first cylinder 1.
[0030] After the liquid inside the storage tank is completely filtered, the gas compression device continues to deliver high-pressure gas into the first cylinder 1 and the temporary storage chamber 13. By closing the third valve on the pressure relief valve 12 and opening the fourth valve at the upper end of the discharge pipe 14, the filtered liquid inside the temporary storage chamber 13 can be quickly discharged from the discharge pipe 14. At this time, in order to avoid a large amount of liquid adhering to the inner wall of the temporary storage chamber 13, the lifting device is activated. The lifting device drives the second cylinder 2 to slide to the bottom of the first cylinder 1. Since the outer wall of the second cylinder 2 is adapted to the inner wall of the first cylinder 1, when the second cylinder 2 descends inside the first cylinder 1, the bottom outer edge of the second cylinder 2 can scrape off the liquid adhering to the inner wall of the temporary storage chamber 13, so that it can be discharged from the discharge pipe 14.
[0031] After the liquid is discharged, some liquid will still adhere to the screw conveyor 7 and filter plate 10. To avoid affecting subsequent filtration, the first valve is closed and the second valve is opened. The lifting device moves the second cylinder 2 upward, ensuring that there is a certain gap between the bottom of the first cylinder 1 and the bottom of the second cylinder 2. Then, cleaning agent is injected into the second cylinder 2 through the liquid inlet pipe 9. The motor 6 drives the screw conveyor 7 to continue rotating, which can clean the inner wall of the second cylinder 2. At the same time, when the liquid flows to the filter plate 10 and enters the gap between the bottom of the first cylinder 1 and the second cylinder 2, it can clean the filter plate 10 and the temporary storage chamber 13, avoiding manual cleaning and reducing the labor intensity of the operators.
[0032] A second valve is provided on the inlet pipe 9. The inlet pipe 9 can be connected to an external cleaning agent storage tank through a hose. A pump body is provided between the cleaning agent storage tank and the inlet pipe 9. The pump body can transport the cleaning agent inside the cleaning agent storage tank to the inside of the second cylinder 2.
[0033] Because the cleaning agent storage tank is equipped with a pump, the cleaning agent can be quickly pumped into the second cylinder 2, which can increase the flow rate of the cleaning agent. At the same time, the heating plate 11 inside the screw conveyor 7 works to ensure the fluidity of the liquid, which facilitates the rapid cleaning of the liquid adhering to the inside of the device.
[0034] The lifting device includes an electric push rod 4, which is mounted on the outer edge of the top of the first cylinder 1 via an mounting ring 3. A connecting plate 5 is installed at the power output end of the electric push rod 4, and the connecting plate 5 can be connected to the top of the first cylinder 1.
[0035] The electric actuator 4 is fixedly connected to the top of the first cylinder 1 via the mounting ring 3. The top of the electric actuator 4 is connected to the top of the second cylinder 2 via the connecting plate 5, which facilitates the electric actuator 4 to drive the second cylinder 2 to move up and down inside the first cylinder 1 to effectively clean the attached liquid. The connecting plate 5 is detachably connected to the top of the second cylinder 2, which facilitates the removal of the second cylinder 2 from the first cylinder 1 to repair or replace the filter plate 10 at the bottom of the second cylinder 2, ensuring the practicality of the device.
[0036] Example 2
[0037] Based on Embodiment 1, the first cylinder 1 is provided with an observation window 16, which is made of borosilicate glass, and the bottom of the second cylinder 2 is equipped with an annular scraper, which can abut against the inner wall of the first cylinder 1.
[0038] The observation window 16 on the first cylinder 1 allows operators to observe whether the temporary storage chamber 13 and the filter plate 10 have been completely cleaned during cleaning, ensuring the filtration quality of the subsequent liquid. The annular scraper installed at the bottom of the second cylinder 2 can abut against the inner wall of the first cylinder 1, making it easy to scrape off all the liquid adhering to the inside of the temporary storage chamber 13, thus improving the cleaning effect of the device on the adhering liquid.
[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, additions, subtractions, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
