Technical Field
[0001] This utility model relates to the field of ethoxyfluorfen technology, specifically a filtration device for the preparation of ethoxyfluorfen. Background Technology
[0002] Ethoxyfluorfen is an organic compound with the molecular formula C15H11ClF3NO4. It is a white to orange or red-brown crystalline solid with a smoky odor. It is produced by reacting 3,4-dichlorotoluene and resorcinol through chlorination, fluorination, etherification, nitration, and alcoholysis. After the ethoxyfluorfen reaction is completed, filtration is generally required before further processing.
[0003] Most existing filtration devices filter the liquid after the reaction by using a filter screen, but the filter screen is inconvenient to remove, making it difficult to clean the impurities inside the filter screen. Utility Model Content
[0004] To address the problem of inconvenient filter screen removal leading to difficulty in cleaning out impurities, the purpose of this invention is to provide a filtration device for the preparation of ethoxyflufenicol.
[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a filtration device for the preparation of ethoxyfluorfen, comprising a barrel body, an inlet at the top of the barrel body, a discharge pipe fixedly passing through the bottom of the barrel body, a filtration assembly inside the barrel body, a sealing assembly on the barrel body, and an agitation assembly inside the barrel body; the filtration assembly comprises a box body and a filter cylinder, the box body being movably inserted into the barrel body, one end of the filter cylinder being inserted through and through one side of the box body, an inlet at the upper surface of the box body, the inlet being aligned with the inlet, a guide plate at the bottom of the box body, and a handle fixedly provided on the side of the box body away from the filter cylinder; the sealing assembly comprises a sealing plate, a cavity at the top of the barrel body communicating with the inlet, the sealing plate being slidably connected within the cavity and aligned with the inlet, the sealing plate moving within the cavity to seal the inlet, and then the handle being used to open the filter cylinder. The box body is removed from the barrel, causing the filter cartridge to move out of the barrel along with the box body. Then, the filter cartridge is rotated and removed from the box body, and impurities inside the filter cartridge are cleaned. This avoids the inconvenience of disassembling and cleaning the filter structure. A positioning ring is fixedly provided at one end of the filter cartridge near the box body. One side of the positioning ring fits against the box body. The positioning ring prevents the filter cartridge from being inserted too much into the box body. A cylinder is fixedly provided on the outside of the barrel body. The driving end of the cylinder moves through the barrel body and is fixedly connected to one side of the sealing plate. The sealing plate can be easily moved by the cylinder. A connecting pipe is fixedly provided inside the inlet. The end of the connecting pipe away from the barrel body is connected to the outlet of the reaction device in the previous process. Liquid can be sent into the barrel body through the connecting pipe. The end of the guide plate near the filter cartridge is lower than the other end of the guide plate. This can easily guide the liquid into the box body and into the filter cartridge. The box body and the filter cartridge are connected by threads, which can easily install the filter cartridge onto the box body.
[0006] Preferably, the agitation assembly includes a rotating shaft symmetrically distributed and rotatably mounted inside the container. A series of agitating rods arranged in a circular array are fixedly mounted on the outer side of the rotating shaft. A symmetrically distributed connecting shaft slides through the bottom of the container, with one end of the connecting shaft fixedly connected to one end of the rotating shaft. A first gear is fixedly sleeved on the outer side of the connecting shaft, and a second gear meshes between the two first gears. A motor is mounted on the lower surface of the container, with the end of the motor's output shaft fixedly connected to the middle of the second gear. The two agitating rods are staggered, and the motor's output shaft drives the second gear to rotate. The second gear drives the two first gears to rotate synchronously, which in turn drives the connecting shaft to rotate. The connecting shaft then drives the rotating shaft to rotate, which in turn drives the agitating rods to rotate, thus agitating the liquid and preventing sedimentation. A fixing plate is fixedly mounted on the lower surface of the container, and the motor is fixedly mounted on the fixing plate for easy installation.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0008] 1. The sealing plate is moved by the drive end of the cylinder, so that the sealing plate blocks the inlet. Then the box is moved out of the barrel, and the box moves the filter cartridge out of the barrel. The filter cartridge is removed from the box and the impurities inside the filter cartridge are cleaned. This avoids the filter structure from being inconvenient to disassemble and clean, thus achieving the purpose of convenient cleaning.
[0009] 2. The second gear drives the two first gears to rotate synchronously. The first gear drives the connecting shaft to rotate, the connecting shaft drives the rotating shaft to rotate, and the rotating shaft drives the stirring rod to rotate, so that the stirring rod stirs the liquid. This can prevent the substances in the liquid from settling, thus achieving the purpose of convenient stirring. Attached Figure Description

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.
[0017] Example: Figure 1-4 As shown, this utility model provides a filtration device for the preparation of ethoxyflufenicol, including a barrel 1, an inlet 5 at the top of the barrel 1, a discharge pipe 6 fixedly passing through the bottom of the barrel 1, a filter assembly 2 inside the barrel 1, a sealing assembly 3 on the barrel 1, and an agitation assembly 4 inside the barrel 1; the filter assembly 2 includes a box 21 and a filter cylinder 22, the box 21 being movably inserted into the barrel 1, one end of the filter cylinder 22 being inserted through and into one side of the box 21, and an inlet 24 on the upper surface of the box 21. The liquid outlet 24 is aligned with the inlet 5. A guide plate 23 is provided at the bottom of the box body 21. A handle 25 is fixedly provided on the side of the box body 21 away from the filter cartridge 22. The sealing assembly 3 includes a sealing plate 31. A cavity 32 is provided at the top of the barrel 1. The cavity 32 is connected to the inlet 5. The sealing plate 31 is slidably connected in the cavity 32 and aligned with the inlet 5. By moving the sealing plate 31 in the cavity 32, the sealing plate 31 seals the inlet 5. Then, the box body 21 is moved out of the barrel 1 by the handle 25, causing the box body 21 to move. The filter cartridge 22 is removed from the barrel 1, then rotated to remove it from the box 21, and the impurities inside the filter cartridge 22 are cleaned. This avoids the inconvenience of disassembling and cleaning the filter structure. A positioning ring 26 is fixedly provided at one end of the filter cartridge 22 near the box 21. One side of the positioning ring 26 fits against the box 21. The positioning ring 26 prevents the filter cartridge 22 from being inserted too deeply into the box 21. A cylinder 33 is fixedly provided on the outside of the barrel 1. The driving end of the cylinder 33 moves through the barrel 1 and is fixedly connected to one side of the sealing plate 31. The cylinder 33 can easily move the sealing plate 31. The inlet 5 is fixedly equipped with a connecting pipe 7. The end of the connecting pipe 7 away from the barrel 1 is connected to the outlet of the reaction device of the previous process. Liquid can be sent into the barrel 1 through the connecting pipe 7. The end of the guide plate 23 near the filter cylinder 22 is lower than the other end of the guide plate 23, which can easily guide the liquid into the box 21 and into the filter cylinder 22. The box 21 and the filter cylinder 22 are connected by threads, which can easily install the filter cylinder 22 onto the box 21.
[0018] The agitation assembly 4 includes a rotating shaft 41, which is symmetrically distributed and rotatably mounted inside the barrel 1. Agitating rods 42 arranged in a circular array are fixedly mounted on the outer side of the rotating shaft 41. A symmetrically distributed connecting shaft 43 slides through the bottom end of the barrel 1. One end of the connecting shaft 43 is fixedly connected to one end of the rotating shaft 41. A first gear 44 is fixedly sleeved on the outer side of the connecting shaft 43. A second gear 45 meshes between the two first gears 44. A motor 46 is mounted on the lower surface of the barrel 1. The end of the output shaft of the motor 46 is fixedly connected to the middle of the second gear 45. The stirring rods 42 are staggered and drive the second gear 45 to rotate through the end of the output shaft of the motor 46. The second gear 45 drives the two first gears 44 to rotate synchronously. The first gears 44 drive the connecting shaft 43 to rotate, the connecting shaft 43 drives the rotating shaft 41 to rotate, and the rotating shaft 41 drives the stirring rods 42 to rotate, so that the stirring rods 42 agitate the liquid. This can prevent the substances in the liquid from settling. A fixing plate 47 is fixedly provided on the lower surface of the barrel 1. The motor 46 is fixedly installed on the fixing plate 47. The fixing plate 47 makes it easy to install the motor 46.
[0019] Working principle: First, the reaction device of the previous process sends liquid into the inlet 5 through the connecting pipe 7. The liquid passes through the liquid inlet 24 into the box 21, and is guided into the filter cylinder 22 by the guide plate 23. The liquid filters impurities through the filter cylinder 22 and falls to the bottom of the barrel 1. At the same time, the motor 46 is started, so that the motor 46 starts to work. The end of the output shaft of the motor 46 drives the second gear 45 to rotate. The second gear 45 drives the two first gears 44 to rotate synchronously. The first gears 44 drive the connecting shaft 43 to rotate. The connecting shaft 43 drives the rotating shaft 41 to rotate. The rotating shaft 41 drives the stirring rod 42 to rotate, so that the stirring rod 42 stirs the liquid. This can prevent the substances in the liquid from settling, thereby achieving the purpose of convenient stirring.
[0020] When the filter cartridge 22 needs to be cleaned, the cylinder 33 is activated, causing the cylinder 33 to start working. The driving end of the cylinder 33 drives the sealing plate 31 to move within the cavity 32, causing the sealing plate 31 to block the inlet 5. Then, the box 21 is moved out of the barrel 1 by the handle 25, causing the box 21 to move the filter cartridge 22 out of the barrel 1. Next, the filter cartridge 22 is rotated to remove it from the box 21, and the impurities inside the filter cartridge 22 are cleaned. This avoids the inconvenience of disassembling and cleaning the filter structure, thus achieving the purpose of convenient cleaning.
[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
