[0001] The present invention relates to the technical field of multi-stage sewage treatment, and particularly to a multi-stage sewage treatment device for pharmaceutical coating production. Background Art

[0002] A multi-stage sewage treatment device for pharmaceutical coating production is a device used to effectively treat the sewage generated during the production of pharmaceutical coatings. Its main purpose is to ensure that the sewage meets the national or local environmental protection standards before discharge, protecting the environment from pollution. During the treatment process of the sewage for pharmaceutical coating production, it is necessary to treat the pharmaceutical coatings that are unqualified or have defects in production. There are many types of pharmaceutical coatings, and among them, water-insoluble film coating materials do not dissolve in water, thus generating water-insoluble dregs. At present, when the multi-stage treatment device treats the sewage for pharmaceutical coating production, due to its water-insoluble characteristics, the pharmaceutical coatings of water-insoluble film coating materials will accumulate and block inside the multi-stage sewage treatment device, thereby affecting the treatment effect of the multi-stage sewage treatment for pharmaceutical coating production.

When the trigger bar 45 leaves the position corresponding to the knocking column 47, the tension spring 49 rebounds to drive the knocking column 47 to rebound while knocking the filter plate 39.

[0028] Working principle: First step, when it is necessary to treat the sewage produced in pharmaceutical coating production, the sewage containing water-insoluble pharmaceutical coating is poured along the feed pipe 5. Then, the sewage with water-insoluble pharmaceutical coating enters the interior of the treatment shell 1 along the feed pipe 5. Then, the starting rod 19 moves, and the starting rod 19 drives the mating block 22 to move. When the starting rod 19 moves, it drives the spring 52 to compress. When the two mating blocks 22 move to the corresponding positions, the mating blocks 22 cut and crush the water-insoluble pharmaceutical coating. When the cutting is completed, the spring 52 rebounds to drive the starting rod 19 to reset, preventing the mating blocks 22 from blocking the sewage flow.

[0029] Second step, start the stepper motor 33. The stepper motor 33 drives the second threaded rod 34 to rotate. When the second threaded rod 34 rotates, it drives the bearing plate 35 connected by threads to move downward. Then, when the bearing plate 35 moves, it drives the placing shell 9 downward. Further, when the second threaded rod 34 rotates, it drives the bevel gear 36 to rotate. When the bevel gear 36 rotates, it drives the single-headed gear column 40 to rotate. When resetting is required, the stepper motor 33 drives the second threaded rod 34 to rotate in the reverse direction. Then, when the second threaded rod 34 rotates in the reverse direction, it drives the bearing plate 35 to move upward. When the bearing plate 35 moves upward, it drives the placing shell 9 to move upward. Then, when the placing shell 9 moves upward, it can realize the action cycle.

[0030] Step 3: When it is necessary to treat the sewage produced in the production of pharmaceutical coatings, start the shell 8 to move downward. Then, when the shell 8 moves, it drives the trigger block 17 to move downward. When the trigger block 17 moves to the position corresponding to the trigger plate 23, the trigger block 17 drives the centralized strip 24 to move. Then, when the shell 8 moves, the sealing gasket 14 and the mating block 22 cooperate to prevent the water-insoluble pharmaceutical coatings from floating. When the connecting block 15 drives the annular blade 29 on one side of the support column 18 to fit with the special-shaped filter plate 30, the mating block 22 fits with the annular blade 29, and then the water-insoluble pharmaceutical coatings on the top of the special-shaped filter plate 30 are crushed. When the annular blade 29 moves to fit with the special-shaped filter plate 30, the pressure rod 13 on the top of the connecting block 15 moves upward. Then, the sealing gasket 14 outside the pressure rod 13 compresses the air inside the compression cylinder 7. When the annular blade 29 resets, the compressed air drives the sealing gasket 14 to rebound and reset. When it is necessary to replace the special-shaped filter plate 30, release the clamping state of the clamping strip 31 and the clamping plate 51, and then clean and replace the special-shaped filter plate 30.

[0031] Step 4: When the sewage produced in the production of pharmaceutical coatings enters the top of the filter plate 39, the single-headed gear column 40 rotates. Then, when the single-headed gear column 40 rotates, it drives the scraping strip 44 to rotate. When the scraping strip 44 rotates, it shovels up the fine particles attached to the top of the filter plate 39. When the fine particles are shoveled up, the collection frame 43 on the top of the scraping strip 44 collects the shoveled fine particles.

[0032] Step 5: When the fine particles are attached to the top of the filter plate 39, the single-headed gear column 40 rotates to drive the trigger strip 45 to rotate. Then, when the trigger strip 45 rotates to the position corresponding to the receiving strip 46, the trigger strip 45 drives the fitted receiving strip 46 to move downward. While the receiving strip 46 moves downward, it drives the knocking column 47 to move into the knocking cylinder 41. Then, when the knocking column 47 moves, it drives the tension spring 49 to stretch. When the trigger strip 45 leaves the position corresponding to the knocking column 47, the tension spring 49 rebounds to drive the knocking column 47 to rebound and knock the filter plate 39 at the same time.
