Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a stirring device for chemical production that is easy to clean. Background Technology

[0002] Chemical production often involves high-viscosity, easily solidified, corrosive, or toxic materials. Traditional mixing devices are prone to material residue, leading to cross-contamination or reaction failure. Traditional mixers also have dead zones that are difficult to clean thoroughly, requiring manual disassembly or high-pressure washing, which is time-consuming and labor-intensive. Therefore, there is a need to design a mixing device for chemical production that is easy to clean.

[0003] To address this, patent CN109092101A discloses a chemical production mixing and blending device with a cleaning function, comprising a mixing tank, a stirring motor located at the center of the upper surface of the mixing tank, a stirring rod located below the stirring motor, stirring frames located on both sides of the stirring rod, and stirring blades located at the end of the stirring rod away from the stirring motor. A cleaning mechanism is located on one side of the mixing tank, a circulation mechanism is located on the other side of the mixing tank, and a shock-absorbing mechanism is located at the bottom of the mixing tank. The cleaning mechanism in the chemical production mixing and blending device allows users to rinse the inner wall of the mixing tank when needed, making cleaning the mixing tank more convenient, time-saving, and labor-saving.

[0004] Although the aforementioned chemical production mixing and blending device can be cleaned by spraying water from the top of the mixing device during use, the impact force of the water flowing to the bottom of the mixing device is weak, and residue is easily left during cleaning. Therefore, it is necessary to design a mixing device for chemical production that is easy to clean. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0030] Please see Figures 1-6 The present invention provides a stirring device for chemical production that is easy to clean, including a stirring component 1.

[0031] Reference Figures 1-6 The mixing assembly 1 includes a mixing tank 11, a mixing chamber 12, a cover 13, a feed pipe 14, and a discharge pipe 15. The mixing tank 11 has a mixing chamber 12 inside. The cover 13 is fixed to the top of the mixing tank 11, and the feed pipe 14 is fixed to one side inside the cover 13. The discharge pipe 15 is fixed to the bottom of the mixing tank 11. A mixing structure 2 is provided on the top of the mixing assembly 1. The mixing structure 2 includes a drive gear 21, a drive motor 22, a sealing block 23, a driven gear 24, a rotating shaft 25, and a mixing rod 26. The drive motor 22 is fixed... Installed on one side of the top of the cover 13, the output end of the drive motor 22 is fixedly connected to the active gear disk 21, the rotating shaft 25 is set on the top of the stirring chamber 12, and stirring rods 26 are fixed on the outer walls on both sides of the rotating shaft 25. The top of the rotating shaft 25 extends to the top of the cover 13 and is fixed with a sealing block 23. A driven gear disk 24 is fixed on the outer wall of the sealing block 23. The active gear disk 21 and the driven gear disk 24 are meshed and connected. The stirring rods 26 are symmetrically distributed on both sides of the rotating shaft 25 and are evenly distributed on the outer side of the rotating shaft 25.

[0032] When an external power source is connected and the drive motor 22 is started, the drive motor 22 will drive the active gear disk 21 to rotate. The active gear disk 21 and the driven gear disk 24 are meshed and connected. When the active gear disk 21 rotates, it will drive the driven gear disk 24 to rotate. The rotation of the driven gear disk 24 will drive the stirring rod 26 to rotate through the rotating shaft 25. The stirring rods 26 are evenly distributed to ensure uniform mixing of materials and prevent sedimentation at the bottom.

[0033] Reference Figures 2-6 The bottom of the stirring structure 2 is fixed with a spraying structure 4. The spraying structure 4 includes a water supply pipe 43 fixed to the bottom of the stirring structure 2. Diverter pipes 42 are evenly fixed on the outer walls of both sides of the water supply pipe 43. A nozzle 41 is fixed at the end of the diverter pipe 42 away from the water supply pipe 43. The spraying structure 4 also includes a water inlet pipe 45 fixed at the middle position of the top of the cover 13. The spraying structure 4 also includes a water delivery chamber 44 opened inside the rotating shaft 25. The diverter pipes 42 are symmetrically distributed on both sides of the water supply pipe 43. The water supply pipe 43 and the rotating shaft 25 are interconnected through the water delivery chamber 44. The bottom end of the water inlet pipe 45 extends into the interior of the sealing block 23 and is rotatably connected to the sealing block 23. The water inlet pipe 45 and the rotating shaft 25 are interconnected through the water delivery chamber 44. The top end of the water inlet pipe 45 is connected to a water tank and a water pump.

[0034] With an external power supply, during cleaning, external water enters the water delivery chamber 44 through the water inlet pipe 45, then enters the interior of the water supply pipe 43, and is sprayed out at high pressure from the nozzle 41 through the diversion pipe 42 to perform high-pressure spraying and washing of the inner wall at the bottom of the mixing tank 11. The diversion pipe 42 and the water supply pipe 43 rotate with the stirring structure 2, so that the water flow can impact the inner wall of the mixing tank 11 at multiple angles. With the help of the wall scraping structure 3, the inner wall of the mixing tank 11 can be thoroughly cleaned.

[0035] Reference Figures 2-6 Both sides of the stirring structure 2 are fixed with scraping structures 3. The scraping structure 3 includes a connecting groove 31, a connecting block 32, a connecting bolt 33, and an elastic scraper 34. The connecting groove 31 is opened at the end of the stirring rod 26 away from the rotating shaft 25. The connecting groove 31 is provided with a connecting block 32 inside. The connecting bolt 33 passes through the inside of the connecting block 32. An elastic scraper 34 is fixed on one side of the connecting block 32. Both ends of the connecting bolt 33 extend to the outside of the stirring rod 26 and are threadedly connected to the stirring rod 26. The elastic scrapers 34 are symmetrically distributed on both sides of the rotating shaft 25. One side of the elastic scraper 34 is in contact with the inner wall of the stirring tank 11.

[0036] During the mixing process, the connecting block 32 rotates with the stirring rod 26. When the connecting block 32 rotates, it can drive the elastic scraper 34 to rotate. When the elastic scraper 34 rotates, it will stick to the tank wall and scrape off the residue. After the wall scraping is completed, water can be sprayed onto the inner wall of the mixing tank 11 through the feed pipe 14. The residue scraped off on one side of the elastic scraper 34 will fall down under the flushing of the high-pressure water flow and be discharged out through the discharge pipe 15, ensuring the cleaning effect of the inner wall of the top of the mixing tank 11. By adjusting the tightness of the connecting bolt 33, the scraper pressure can be controlled to adapt to high viscosity or easily solidified materials.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
