[0002] Chemical liquids are various liquid media produced or used in chemical production processes. Due to factors such as production processes, they are mixed with harmful substances such as solid particles. These impurities not only affect the purity and quality of chemical products, but may also increase equipment maintenance costs and production safety hazards. Therefore, before chemical liquids enter subsequent processes, they need to be separated by special filtration devices.

[0003] Common automated chemical liquid filtration devices mostly use fixed filter cartridges as filtration components. The chemical liquid to be filtered is introduced into the filtration chamber, and the liquid flows through the filter cartridge to intercept impurities. However, because the filter cartridge is in a stationary state, impurities are easy to adhere to the inside of the filter cartridge, causing the filter screen to become clogged.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of this utility model provides an automated chemical liquid filtration device, comprising a first outer shell 1, a motor 2 fixedly connected to the upper surface of the first outer shell 1, a drive wheel 3 fixedly provided at the output end of the motor 2, a driven wheel 4 meshing with the tooth end of the drive wheel 3, a transmission shaft 5 fixedly connected to the inner wall of the driven wheel 4, a first partition 6 rotatably connected to the outer wall of the transmission shaft 5, a connecting plate 7 fixedly connected to the lower surface of the transmission shaft 5, a filter cylinder 8 fixedly connected to the outer wall of the connecting plate 7, a fixing plate 9 rotatably connected to the outer wall of the filter cylinder 8, a second partition 10 rotatably connected to the outer wall of the filter cylinder 8, a waste outlet 11 rotatably connected to the inner wall of the filter cylinder 8, a support leg 15 fixedly connected to the outer wall of the first outer shell 1, and an inlet / outlet assembly provided inside the first outer shell 1 for material conveying of the device;

[0026] Specifically, by starting motor 2, the driving wheel 3 rotates, causing the driven wheel 4 to rotate intermittently, which in turn drives the transmission shaft 5 to rotate intermittently. This, in turn, causes the connecting plate 7 and the filter cylinder 8 to rotate intermittently along the central axis of the transmission shaft 5. The first outer casing 1 serves to fix motor 2, preventing it from changing position during operation. After the driving wheel 3 rotates a certain angle, the teeth of the driving wheel 3 mesh with the teeth of the driven wheel 4, causing the driven wheel 4 to rotate. Simultaneously, after rotating a certain angle, the driving wheel 3 no longer meshes with the driven wheel 4. At this point, the driving wheel 3 remains in a self-rotating state, while the driven wheel 4 remains stationary. This allows the driven wheel 4 to rotate intermittently while the driving wheel 3 rotates. The driven wheel 4 is fixed to the outer wall of the transmission shaft 5, ensuring that during its intermittent rotation, the driven wheel 4 drives the transmission shaft 5 to rotate synchronously along the central axis of the driven wheel 4, preventing the driven wheel 4 from falling off during rotation and causing the teeth to disengage from the driving wheel. The first partition 6 restricts the transmission shaft 5, limiting its rotation along the interior of the first partition 6 during rotation and preventing it from changing position. The transmission shaft 5 fixes the connecting plate 7, which is also fixed to the inner wall of the filter cylinder 8. Thus, when the transmission shaft 5 rotates, it can drive the connecting plate 7 and the filter cylinder 8 to rotate intermittently along the central axis of the transmission shaft 5 without changing position. The fixing plate 9 and the second partition 10 provide rotational support for the filter cylinder 8, improving its stability during rotation. The inner wall of the filter cylinder 8 rotates on the outer wall of the waste outlet 11, preventing the filter cylinder 8 from rotating the waste outlet 11. The support leg 15 fixes the first outer shell 1, ensuring that the first outer shell 1 and other internal components remain stable during filtration. The intermittently rotating filter cylinder 8 not only removes attached impurities but also prevents local blockage.

[0027] Reference Figure 1 and Figure 2The feeding and discharging assembly includes a feeding port 12, the outer wall of the feeding port 12 is disposed inside the first housing 1, a guide tube 13 is fixedly connected to the inner wall of the feeding port 12, and a discharging port 14 is fixedly connected to the inside of the first housing 1.

[0028] Specifically, the chemical liquid is added through the inlet 12 and enters the interior of the first outer shell 1 through the guide tube 13. The first outer shell 1 restricts the position of the inlet 12 and the guide tube 13, so that the chemical liquid flowing out through the guide tube 13 falls into the interior of the filter cylinder 8 for filtration, preventing it from flowing to the outside of the filter cylinder 8 and thus failing to be filtered.

[0029] Reference Figure 2 and Figure 4 The outer wall of the drive shaft 5 is rotatably connected to the inside of the first housing 1, and the outer wall of the first partition 6 is fixedly connected to the inner wall of the first housing 1.

[0030] Specifically, the first outer shell 1 restricts the transmission shaft 5, preventing it from rotating inside the first outer shell 1 during rotation and thus preventing it from changing position during rotation. The first outer shell 1 also fixes the first partition 6, preventing the first partition 6 from being dislodged by force when the transmission shaft 5 rotates inside the first partition 6.

[0031] Reference Figure 2 and Figure 4 The outer wall of the fixing plate 9 is fixedly connected to the inner wall of the first outer shell 1, and the outer wall of the second partition plate 10 is fixedly connected to the inner wall of the first outer shell 1.

[0032] Specifically, the first outer shell 1 serves to fix the fixing plate 9 and the second partition 10, preventing the fixing plate 9 and the second partition 10 from falling off under force when the filter cylinder 8 rotates inside the fixing plate 9 and the second partition 10.

[0033] Reference Figure 1 and Figure 2 The waste outlet 11 is fixedly connected inside the second partition 10, and the bottom of the filter cylinder 8 is conical.

[0034] Specifically, the second partition 10 fixes the waste outlet 11, ensuring the seal between the filter cylinder 8 and the waste outlet 11. The bottom of the filter cylinder 8 is conical, which effectively prevents the accumulation of fallen impurities at the bottom, allowing the impurities to smoothly enter the waste outlet 11.

[0035] Reference Figure 2 , Figure 5 and Figure 6A pin-hole disc 16 is fixedly connected to the lower surface of the first partition 6. A second outer shell 17 is provided on the lower surface of the pin-hole disc 16. A scraper 18 is fixedly connected to the outer wall of the second outer shell 17. A limiting block 19 is provided inside the second outer shell 17. A connecting block 20 is fixedly connected to the lower surface of the limiting block 19. A knob 21 is fixedly connected to the lower surface of the connecting block 20. A spring 22 is fixedly connected to the outer wall of the limiting block 19. A cylindrical pin 23 is fixedly connected to the upper surface of the limiting block 19. A limiting block 24 is fixedly connected to the outer wall of the cylindrical pin 23. The outer wall of the connecting block 20 is slidably connected to the inside of the second outer shell 17. The outer wall of the spring 22 is located inside the second outer shell 17. The outer wall of the cylindrical pin 23 slides inside the second outer shell 17. The outer wall of the cylindrical pin 23 slides inside the pin-hole disc 16. The limiting block 24 slides on the inner wall of the pin-hole disc 16.

[0036] Specifically, by aligning the cylindrical pin 23 and the limiting block 24 with the slot opened in the pin hole disk 16 and placing them into the interior of the pin hole disk 16, until the second outer shell 17 is in contact with the pin hole disk 16, then rotating the knob 21 causes the connecting block 20 to push the limiting block 19, the cylindrical pin 23, and the limiting block 24, and compress the spring 22. After the limiting block 24 enters the interior of the pin hole disk 16, rotating the knob 21 causes the connecting block 20 to rotate, thereby causing the cylindrical pin 23 and the limiting block 24 to rotate. 4. After rotating the disc 24 to fit the inner bottom surface of the pin hole disc 16, release the knob 21. At this time, the spring 22 rebounds and pushes the limiting block 19 to reset the cylindrical pin 23, thereby clamping the limiting block 24 with the inner bottom surface of the pin hole disc 16. The first partition 6 fixes the pin hole disc 16 to prevent it from falling off due to gravity, and the second outer shell 17 fixes the scraper 18 to prevent it from falling off due to the force of the intermittently rotating filter cylinder 8. The scraper 18 can improve the cleaning effect of adhering impurities. The second outer shell 17 guides the limiting block 19, connecting block 20, and cylindrical pin 23, allowing them to rotate or slide only within the second outer shell 17. The limiting block 19 fixes the connecting block 20, while the knob 21 of the connecting block 20 is fixed, so that when the knob 21 rotates or slides, it can drive the connecting block 20 and the limiting block 19 to rotate or slide synchronously. The limiting block 19 limits the sliding distance of the knob 21 and the connecting block 20. The limiting block 19 also fixes the cylindrical pin 23, limiting its sliding distance while driving it to rotate or slide. The spring 22 returns the limiting block 19 to its original position upon rebound. The outer wall of the limiting block 24 fits against the outer wall of the pin hole disc 16 to prevent gaps that could lead to insufficient stability, thus fixing the position of the scraper 18. This allows for quick installation and removal of the scraper 18, making it convenient to clean or replace the scraper 18 after each use.

[0037] Working Principle: When using this device for chemical liquid filtration, the chemical liquid is first input through the inlet 12 inside the first outer casing 1. The liquid enters the guide tube 13 through the inlet 12 and then into the filter cylinder 8 fixed by the fixed plate 9. The starting motor 2 drives the drive wheel 3 to rotate, causing the driven wheel 4 to rotate intermittently. This, in turn, drives the transmission shaft 5 to rotate intermittently inside the first partition 6, which in turn drives the connecting plate 7 and the filter cylinder 8 fixed to the outer wall of the connecting plate 7 to rotate intermittently along the central axis of the transmission shaft 5. The intermittent rotation of the filter cylinder 8, in conjunction with the scraper 18, not only removes adhering impurities but also prevents localized blockages. The removed impurities are discharged from the waste outlet 11 inside the second partition 10, while the filtered chemical liquid is output from the outlet 14. The support legs 15 ensure the stability of the device during use.

[0038] When the scraper 18 needs to be installed after cleaning, align the cylindrical pin 23 and the limiting block 24 with the slot opened in the pin hole disc 16 and put them into the inside of the pin hole disc 16 until the second outer shell 17 is in contact with the pin hole disc 16. Then, rotate the knob 21 to make the connecting block 20 push the limiting block 19, the cylindrical pin 23, and the limiting block 24, and press the spring 22. After the limiting block 24 enters the inside of the pin hole disc 16, rotate the knob 21 to make the connecting block 20 rotate, thereby making the cylindrical pin 23 and the limiting block 24 rotate. After the limiting block 24 rotates to fit the inner bottom surface of the pin hole disc 16, release the knob 21. At this time, the spring 22 rebounds and pushes the limiting block 19 to make the cylindrical pin 23 return to its original position, so that the limiting block 24 and the inner bottom surface of the pin hole disc 16 form a clamp, thereby fixing the position of the scraper 18 and achieving the effect of quickly installing the scraper 18.

[0039] In other words, when the device is in use, it not only achieves the effect of removing attached impurities and avoiding local blockage, but also achieves the effect of quickly installing and removing the scraper 18, making it convenient to clean or replace the scraper 18 after each use.
