Description

Technical Field

[0001] This utility model relates to the field of polymerization inhibitor production technology, and in particular to a polymerization inhibitor production filtration device. Background Technology

[0002] Polymerization inhibitors are industrial additives typically used to prevent polymerization. Inhibitor molecules react with chain free radicals to form non-free radical substances or low-activity free radicals that cannot be initiated, thereby terminating the polymerization. Filtration is a crucial step in the production of polymerization inhibitors.

[0003] Existing filtration devices typically filter polymerization inhibitors using a filter screen. This filtration relies on the flowability of the inhibitor, resulting in low efficiency and impacting production efficiency. Furthermore, the filter screen is prone to clogging, requiring frequent shutdowns for cleaning, further hindering production. Therefore, this paper proposes a polymerization inhibitor production filtration device to address these issues. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-5 As shown, the present invention proposes a filtration device for producing polymerization inhibitors, which includes a filter box 1, a filtration mechanism 2 inside the filter box 1, and a rinsing mechanism 3 outside the filter box 1.

[0024] In this invention, the filtration mechanism 2 can filter the polymerization inhibitor quickly and thoroughly, improving the filtration efficiency of the polymerization inhibitor. After filtration, the rinsing mechanism 3 can rinse the filtration mechanism 2 to prevent clogging. In addition, after long-term use, the filtration mechanism 2 can be disassembled to facilitate cleaning of the filter box 1 and the filtration mechanism 2.

[0025] In an optional embodiment, the filter mechanism 2 includes a U-shaped frame 21, a drive motor 22, a rotating rod 23, a mounting plate 24, a feed pipe 25, a filter cylinder 26, a mounting assembly 27, and a door 28. The U-shaped frame 21 is located on the top of the filter box 1, the drive motor 22 is located on the top of the U-shaped frame 21, the rotating rod 23 is rotatably connected to the top of the filter box 1 and extends into it, the output end of the drive motor 22 is connected to the top end of the rotating rod 23 through a reducer, and the mounting plate 24 is located on the top of the filter box 1. At the bottom of the rotating rod 23, the feed pipe 25 is located inside the rotating rod 23. The bottom end of the feed pipe 25 extends to the bottom of the mounting plate 24. The other end of the feed pipe 25 is located above the filter box 1 and is connected to the outside. The filter cylinder 26 is located at the bottom of the mounting plate 24. The mounting assembly 27 is located at the bottom of the mounting plate 24. The mounting plate 24 is connected to the filter cylinder 26 through the mounting assembly 27. The box door 28 is hinged to the outside of the filter box 1 through a hinge. The filter box 1 corresponds to the filter cylinder 26.

[0026] It should be noted that when the polymerization inhibitor needs to be filtered, the polymerization inhibitor is added into the filter cylinder 26 through the feed pipe 25. Then, the drive motor 22 is started. The output shaft of the drive motor 22 drives the rotating rod 23 to rotate. The rotating rod 23 drives the mounting plate 24 to rotate. Under the action of the mounting assembly 27, the mounting plate 24 drives the filter cylinder 26 to rotate. The filter cylinder 26 drives the polymerization inhibitor inside to rotate. Through the centrifugal force of the polymerization inhibitor, the polymerization inhibitor can quickly pass through the filter cylinder 26 for filtration, which improves the filtration effect of the polymerization inhibitor and thus improves the production efficiency of the polymerization inhibitor.

[0027] In addition, viewed from the front to the back, the shielding area of ​​the door 28 is larger than that of the filter cylinder 26. After long-term use, the door 28 can be opened and the filter cylinder 26 can be disassembled through the mounting component 27. Then the filter cylinder 26 can be taken out from the inside of the filter box 1, which makes it convenient to replace the filter cylinder 26 and clean it thoroughly.

[0028] In an optional embodiment, the mounting assembly 27 includes two mounting blocks 271, two connecting grooves 272, a connecting block 273, two threaded grooves 274, two threaded rods 275, and two knobs 276. The two mounting blocks 271 are both located at the bottom of the mounting plate 24 and are symmetrically distributed. The two connecting grooves 272 are respectively opened on opposite sides of the two mounting blocks 271, and the front of the two connecting grooves 272 is connected to the outside. The two connecting blocks 273 are respectively located on the outside of the filter cylinder 26 and are slidably connected to the inside of the two connecting grooves 272. The two threaded grooves 274 are respectively opened at the bottom of the two connecting blocks 273. The two threaded rods 275 are respectively located at the bottom of the two mounting blocks 271 and extend into the inside of the two threaded grooves 274. The two threaded rods 275 are respectively threadedly connected to the two threaded grooves 274. The two knobs 276 are respectively located at the bottom end of the two threaded rods 275.

[0029] It should be noted that when the filter cylinder 26 needs to be disassembled, turn the two knobs 276. The two knobs 276 will drive the two threaded rods 275 to rotate respectively. When the two threaded rods 275 are disengaged from the two threaded grooves 274 respectively, the two connecting blocks 273 can be removed from the two connecting grooves 272 respectively, so that the filter cylinder 26 can be disassembled and removed from the box door 28.

[0030] In addition, when installing the filter cylinder 26, it is necessary to send the filter cylinder 26 into the filter box 1 through the box door 28, and slide the two connecting blocks 273 into the two connecting grooves 272. Then, rotate the two knobs 276 in the opposite direction. The two knobs 276 will drive the two threaded rods 275 to rotate in the opposite direction. When the two threaded rods 275 are threadedly connected to the two threaded grooves 274 respectively, the connecting blocks 273 can be fixed by the threaded rods 275 and the threaded grooves 274, thereby fixing the filter cylinder 26 and ensuring that the filter cylinder 26 can rotate with the mounting plate 24.

[0031] In an optional embodiment, the rinsing mechanism 3 includes a water pump 31, a connecting pipe 32, and multiple nozzles 33. The water pump 31 is located outside the filter box 1, the connecting pipe 32 is connected to the outlet of the water pump 31, and the other end of the connecting pipe 32 extends into the interior of the filter box 1. The multiple nozzles 33 are all connected to the outside of the connecting pipe 32, and the multiple nozzles 33 are all corresponding to the filter cylinder 26. The inlet of the water pump 31 is connected to the cleaning liquid tank through the inlet pipe. The bottom of the filter cylinder 26 is connected to a drain pipe, and a first valve is provided inside the drain pipe.

[0032] It should be noted that after the polymerization inhibitor is filtered, the first valve is opened through the box door 28, and then the water pump 31 is started. The water pump 31 draws the cleaning solution through the water inlet pipe and sends it into the connecting pipe 32. Finally, it is sprayed out through multiple nozzles 33. Under the action of spray pressure, the cleaning solution washes the filter cylinder 26, washing off the impurities on the filter cylinder 26 and preventing the filter cylinder 26 from becoming clogged. When washing the filter cylinder 26, the drive motor 22 makes the filter cylinder 26 rotate, so that the filter cylinder 26 can be thoroughly washed. The washed-off impurities and cleaning solution are discharged through the drain pipe. When filtering the polymerization inhibitor, the first valve is closed to prevent the polymerization inhibitor from falling through the drain pipe.

[0033] In addition, when rinsing the filter cylinder 26, it is only possible to ensure that impurities do not clog the filter cylinder 26 as much as possible, and to allow the impurities to fall through the discharge pipe as much as possible. However, it is not possible to thoroughly clean the filter cylinder 26, and some impurities will remain inside the filter cylinder 26. After a period of use, the impurities remaining inside the filter cylinder 26 can be cleaned by disassembling the filter cylinder 26, thereby thoroughly cleaning the inside of the filter cylinder 26.

[0034] In an optional embodiment, the bottom of the filter box 1 is provided with four evenly distributed support columns 4, the bottom of the filter box 1 is connected to a discharge pipe 5 that extends into its interior, the discharge pipe 5 is provided with a second valve, and the outside of the filter box 1 is provided with a controller.

[0035] It should be noted that the filter box 1 can be stably supported by the four support columns 4. When filtering the polymerization inhibitor, the filtered polymerization inhibitor can be discharged from the discharge pipe 5 by opening the second valve. When cleaning the filter cylinder 26, the wastewater can be discharged through the discharge pipe 5.

[0036] In addition, both the drive motor 22 and the water pump 31 are electrically connected to the controller, which can control the drive motor 22 and the water pump 31.

[0037] Working principle:

[0038] In this polymerization inhibitor production filtration device, during use, the polymerization inhibitor is added into the filter cylinder 26 through the feed pipe 25. After feeding is complete, the feed pipe 25 is disconnected, and then the drive motor 22 is started, causing the filter cylinder 26 to rotate. The filter cylinder 26 drives the polymerization inhibitor inside to rotate, and the centrifugal force of the polymerization inhibitor allows it to pass through the filter cylinder 26 quickly, improving the filtration effect. After filtration is complete, the first valve is opened through the door 28, and then the water pump 31 and the drive motor 22 are started. The water pump 31 pumps the cleaning solution through the water inlet pipe. The cleaning fluid is extracted and fed into the connecting pipe 32, and finally sprayed out through multiple nozzles 33. Under the action of spray pressure, the cleaning fluid washes the filter cylinder 26, washing away the impurities on the filter cylinder 26 and preventing the filter cylinder 26 from clogging. The filter cylinder 26 can be thoroughly washed by rotating it. After a period of use, the box door 28 can be opened, and the filter cylinder 26 can be disassembled through the installation component 27. Then, the filter cylinder 26 can be taken out from the filter box 1 for thorough cleaning or replacement.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
