Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and specifically to a pharmaceutical water circulation treatment device with self-cleaning and sterilization functions. Background Art

[0002] The characteristics of water used in the pharmaceutical industry are complex composition, high organic matter content, high toxicity, deep color, and high salt content. Especially, its biodegradability is very poor, and it is discharged intermittently, belonging to industrial wastewater that is difficult to treat. How to treat this kind of wastewater is a difficult problem in environmental protection today. Pharmaceutical water needs to be filtered before discharge to remove substances that will pollute the environment. The existing filtering devices have poor filtering effects and cannot effectively remove harmful substances in the wastewater.

[0003] The Chinese patent discloses a pharmaceutical water stratification filtering device (authorization publication number CN214990778U). Through the settings of stirring blades, feed inlets, and fine filtering plates, when in use, staff introduce wastewater into the stirring tank through the connecting water inlet pipe, then put flocculants from the feed inlets, start the motor to drive the stirring rod to rotate, thereby driving the stirring blades to stir, which can better make the impurities in the wastewater react with the flocculants. Then, it enters the filtering tank through the conveying pipe, filters out larger substances through the coarse filtering plate, and filters out smaller substances through the fine filtering plate, improving the filtering effect and effectively removing harmful substances in the wastewater.

[0004] However, it has certain drawbacks:

[0005] First, its fixed stirring design leads to significant stratification of the fluid in the tank. When the stirring blades only rotate horizontally, laminar flow states are easily formed for liquids with different densities, the contact area between the flocculants and impurities is limited, and the reaction efficiency is low. Especially when treating high-turbidity wastewater, the fixed stirring depth is difficult to penetrate the bottom sediment, causing a stirring blind area, resulting in insufficient flocculation reaction and ultimately affecting the subsequent filtering effect.

[0006] Second, during long-term operation, flocs and impurities continuously adhere to the tank wall, forming a dirt layer that is difficult to remove. These residues become a breeding ground for microorganisms, leading to secondary pollution of the water quality. It is necessary to regularly disassemble the tank body for manual scraping and washing, increasing the maintenance cost. Summary of the Invention

[0037] The water outlet pipe 15 is provided with a valve, which is used to discharge the filtered pharmaceutical water after being opened.

[0038] In Figure 1 , Figure 2 , Figure 4 and Figure 5 : On the upper surface of the base 1, displacement mechanisms 18 for driving the treatment tank body 2 to lift are arranged on both the left and right sides of the treatment tank body 2. The displacement mechanism 18 includes a support plate 19. The lower end of the support plate 19 is fixedly connected to the upper surface of the base 1. The rear surface of the support plate 19 is fixedly connected with a second motor 20. The output end of the second motor 20 is fixedly connected with a first gear 21. A support rod 22 is rotatably connected to the front surface of the support plate 19 below the first gear 21. A second gear 23 is fixedly sleeved on the outside of the support rod 22. The first gear 21 is meshed with the second gear 23. A turntable 24 is fixedly sleeved on the outside of the support rod 22 in front of the second gear 23.

The lower end of the front surface of the slide rod 26 is rotatably connected to the outer edge of the front surface of the turntable 24. The upper end of the slide rod 26 is fixedly connected with a support block 29. One end of the support block 29 is fixedly connected to one side surface of the treatment tank body 2;

[0039] The second motor 20 is equipped with a brake, that is, after power-off, the motor shaft cannot rotate, and it is used to drive the first gear 21 to rotate;

[0040] The rotation of the turntable 24 can drive the slide rod 26 to move up and down through the rotating plate 28, thereby driving the processing tank body 2 to move up and down, enabling the stirring blade 8 to generate a displacement in the vertical direction while performing horizontal stirring, increasing the stirring range, avoiding the flow dead zone caused by fluid stratification or density difference, and improving the mixing uniformity;

[0041] When the slide rod 26 descends to the lowest end, the lower surface of the processing tank body 2 just fits the upper surface of the base 1.

[0042] In Figure 1 、 Figure 2 and Figure 6 : A scraping mechanism 30 is provided on the upper surface of the tank cover 3. The scraping mechanism 30 includes a rotating pipe 31. The rotating pipe 31 movably penetrates the upper surface of the tank cover 3. The stirring rod 7 movably passes through the rotating pipe 31. A shell-type bearing 32 is fixedly sleeved on the upper end of the outer side of the rotating pipe 31. The shell-type bearing 32 is fixedly connected to the upper surface of the tank cover 3. Slide holes 33 are opened on the front and rear surfaces of the rotating pipe 31 below the shell-type bearing 32. A slider 34 is slidably connected inside the slide hole 33. The slider 34 is fixedly connected to one side surface of the stirring rod 7. L-shaped scraping plates 35 are fixedly connected to the left and right surfaces of the rotating pipe 31 below the shell-type bearing 32. The L-shaped scraping plates 35 are movably attached to the inner surface of the processing tank body 2;

[0043] The rotating pipe 31 is fixedly connected to the inner ring of the shell-type bearing 32 (the inner ring and the outer ring of the bearing are in a mutually rotating state), so it is in a mutually rotating state with the shell-type bearing 32;

[0044] When the stirring rod 7 rotates, it can drive the rotating pipe 31 to rotate through the slider 34, thereby driving the L-shaped scraping plates 35 to clean the inner wall of the processing tank body 2 and preventing impurities from adhering to the inner wall of the processing tank body 2;

[0045] When the processing tank body 2 is at the lowest position, the slider 34 is located at the upper end position inside the slide hole 33; when the processing tank body 2 is at the highest position, the slider 34 is located at the lower end position inside the slide hole 33.

[0046] The working principle of the present invention is:

[0047] After the pharmaceutical water and the flocculant are injected into the processing tank body 2 through the feed pipe of the tank cover 3, the first motor 6 drives the stirring rod 7 to drive the multi-layer stirring blades 8 to perform horizontal rotary stirring. At the same time, the second motors 20 of the two displacement mechanisms 18 drive the turntable 24 to rotate through the gear set, driving the slide rod 26 to move up and down, causing the overall lifting of the processing tank body 2. This lifting movement enables the stirring blades 8 to form a three-dimensional stirring trajectory in the tank, breaking the flow dead zone of traditional fixed stirring and ensuring the full mixing of liquids with different densities in the tank;

[0048] During the stirring process, the rotation of the stirring rod 7 drives the rotating pipe 31 and the L-shaped scraper 35 to rotate synchronously through the cooperation of the slider 34 and the sliding hole 33. The L-shaped scraper 35 rotates closely against the inner wall of the treatment tank body 2, scraping off the adhered flocculants in real time to prevent impurity accumulation. When the treatment tank body 2 is lifted or lowered, the relative sliding of the sliding hole 33 and the slider 34 enables the scraper to always maintain effective contact with the tank wall, ensuring that the inner wall can be thoroughly cleaned regardless of whether the tank body is in the high position or the low position.

[0049] After the mixing is completed, the water pump 9 pumps the liquid out through the valve 4 and sends it into the filter box body 13 through the second water pipe 11. The purified water filtered by the filter plate 17 is discharged from the water outlet pipe 15, and the continuous purification of pharmaceutical water is achieved through physical filtration and mechanical cleaning.
