Abstract
Description
Technical Field
[0001] This application relates to the field of bottom discharge and residue prevention technology, and in particular to a bottom discharge and residue prevention structure for a stirred tank used in the production of defoamers. Background Technology
[0002] A stirred tank is a type of mixing equipment widely used in industries such as chemical, food, pharmaceutical, and coating. It is mainly used to realize the stirring, mixing, dispersion, and reaction processes of materials. In the production process of defoamer, the stirred tank is the core reaction equipment, and the residue problem in its discharge stage has long restricted production efficiency and product quality.
[0003] Traditional stirred tanks typically use a flat discharge structure at the bottom, which easily leads to material sedimentation at the bottom and side walls. This is especially problematic for high-viscosity, particulate defoamers. Failure to clean this properly not only wastes resources but also increases the risk of batch-to-batch cross-contamination. Therefore, we propose a bottom discharge structure to prevent residue buildup in stirred tanks used in defoamer production. Utility Model Content

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0027] This application discloses a bottom discharge and residue prevention structure for a stirred tank used in the production of defoamers. For example... Figures 1-5 As shown, it includes:
[0028] Mixing vessel shell 1: A cover plate 2 is inserted and installed on the top of the mixing vessel shell 1, and a motor 3 is fixedly installed on the top of the cover plate 2; a rotating roller 7 is rotatably installed inside the mixing vessel shell 1, and several stirring blades 8 are fixedly installed on the circumferential wall of the rotating roller 7. Three support rods 9 are fixedly installed at one end of each of the stirring blades 8. A sliding groove 12 is opened in each of the three support rods 9. A scraper 10 is slidably installed in the sliding groove 12. Several springs 18 are fixedly installed in the sliding groove 12 and on one side of the scraper 10. Three scraper 2 11 are fixedly installed at the lower end of the rotating roller 7 and directly below the stirring blades 8.
[0029] The discharge pipe 6 is fixedly installed at the bottom of the mixing tank shell 1. An annular air pipe 13 is sleeved on the discharge pipe 6. Several nozzles 14 are fixedly installed on the inner wall of the annular air pipe 13, and one end of each nozzle 14 extends through the outer wall of the discharge pipe 6 into the interior.
[0030] Drive assembly: The drive assembly is located on the cover plate 2 and is used to drive the stirring blade 8 to rotate;
[0031] Jet assembly: The jet assembly is located on one side of the mixing vessel shell 1 and is used to drive several nozzles 14 to jet into the discharge pipe 6.
[0032] In this process, an appropriate amount of defoamer material is added into the mixing tank shell 1. The drive assembly drives the rotating roller 7 to rotate, which in turn drives several stirring blades 8 to rotate, mixing the defoamer material in the mixing tank shell 1. At the same time, the rotating stirring blades 8 drive the scraper 10 to rotate. Under the elastic action of the spring 18, the scraper 10 adheres tightly to the inner wall of the mixing tank, scraping off the material adhering to the inner wall of the mixing tank shell 1. The spring 18 can automatically adapt to changes in the curvature of the side wall to ensure a tight fit. The scraper 2 11 at the lower end of the stirring blades 8 rotates synchronously with the stirring blades 8, directly scraping the bottom of the mixing tank shell 1 to prevent the material from accumulating at the bottom of the inner cavity of the mixing tank shell 1. The material is discharged through the discharge pipe 6 under the pushing action of gravity and the stirring blades 8. The stirring blades 8 continue to rotate. The scraper blades 10 and 11 operate synchronously, stirring and cleaning the side walls and bottom residues simultaneously to ensure efficient material discharge. The bottom of scraper blade 11 is close to the bottom of the inner cavity of the mixing tank shell 1, pushing the material into the discharge pipe 6 without dead angles. After the defoamer material in the mixing tank shell 1 is basically emptied, high-pressure gas is delivered to the annular air pipe 13 through the jet assembly. The airflow is then sprayed onto the inner wall of the discharge pipe 6 through the inclined nozzle 14. The airflow covers the entire inner wall of the discharge pipe 6, blowing away any adhering trace amounts of material to the valve 16 for discharge. This ensures that the defoamer material adhering to the mixing tank shell 1 and the inner wall of the discharge pipe 6 can be cleaned in a timely manner, avoiding residue and greatly reducing resource waste. It also avoids the risk of cross-contamination.
[0033] Please see Figure 1 , Figure 2 and Figure 3 The driving components include:
[0034] Motor 3 is fixedly installed on the top of cover plate 2. The output shaft of motor 3 passes through the top of cover plate 2 and is coaxially connected to rotating roller 7.
[0035] In this process, the motor 3 is connected to the power supply and started, and the output shaft of the motor 3 rotates, driving the rotating roller 7 to rotate.
[0036] Please see Figure 3 The output shaft of motor 3 is rotatably connected to cover plate 2.
[0037] This ensures that motor 3 can operate normally on cover plate 2.
[0038] Please see Figure 2 and Figure 5 The jet assembly includes:
[0039] Air pump 17 is located on one side of the mixing vessel shell 1, and a connecting pipe 15 connects the air pump 17 to the annular air pipe 13.
[0040] When the air pump 17 is connected to the power supply and started, the air pump 17 draws in outside air and compresses it. The compressed air enters the annular air pipe 13 through the connecting pipe 15 and sprays airflow onto the inner wall of the discharge pipe 6 through the inclined nozzle 14. The airflow covers the entire inner wall of the discharge pipe 6 and blows the adhering trace materials to the valve 16 for discharge.
[0041] Please see Figure 1 and Figure 2 The top of the cover plate 2 is fixedly installed with a feed hopper 4, and a plug plate 5 is inserted into the feed inlet of the feed hopper 4. The annular air pipe 13 is fixed to the discharge pipe 6 by several bolts, and the nozzle 14 has an inclined structure.
[0042] The design of the feed hopper 4 can guide the material to be poured into the mixing tank shell 1 in a concentrated manner, avoiding the spillage or accumulation of material at the connection between the cover plate 2 and the shell when manually poured, thus improving the feeding efficiency. The insert plate 5 is inserted into the feed inlet of the feed hopper 4. The feed channel can be quickly opened or closed by pushing and pulling the insert plate 5, which is convenient for controlling the feed amount and ensuring the stability of the structure of the annular air pipe 13 and the discharge pipe 6.
[0043] Please see Figure 1 , Figure 2 and Figure 5 A valve 16 is fixedly installed on the circumferential wall of the discharge pipe 6 and directly below the annular air pipe 13.
[0044] Among them, it is ensured that the discharge of defoamer material inside the mixing tank shell 1 can be controlled through valve 16.
[0045] Please see Figure 3 One end of scraper 10 contacts the inner wall of the mixing vessel shell 1, and the bottom end of scraper 21 contacts the bottom of the inner cavity of the mixing vessel shell 1.
[0046] Specifically, scraper 10 is designed to scrape off the defoamer material on the mixing tank shell 1, and scraper 2 11 is designed to scrape off the defoamer material at the bottom of the inner cavity of the mixing tank shell 1, thus preventing accumulation.
[0047] The implementation principle of the bottom discharge anti-residue structure of the mixing tank for defoamer production in this application embodiment is as follows: Open the insert plate 5, add an appropriate amount of defoamer material into the mixing tank shell 1 through the feed hopper 4, and then close the insert plate 5. Connect the motor 3 to the power supply and start it. The output shaft of the motor 3 rotates, driving the rotating roller 7 to rotate. The rotating roller 7 drives several stirring blades 8 to rotate, stirring and mixing the defoamer material in the mixing tank shell 1. Simultaneously, the rotating stirring blades 8 drive the scraper 10 to rotate. Under the elastic action of the spring 18, the scraper 10 adheres tightly to the inner wall of the mixing tank, scraping off the material adhering to the inner wall of the mixing tank shell 1. The spring 18 can automatically adapt to changes in the curvature of the side wall to ensure a tight fit. The scraper 2 11 at the lower end of the stirring blade 8 rotates synchronously with the stirring blade 8, directly scraping the bottom of the mixing tank shell 1 to prevent material from accumulating at the bottom of the inner cavity of the mixing tank shell 1.
[0048] When discharge is required, open valve 16 at the bottom of discharge pipe 6. The material is discharged through discharge pipe 6 under the influence of gravity and the pushing action of stirring blade 8. Stirring blade 8 rotates continuously, and scraper blades 10 and 11 operate synchronously, simultaneously stirring and cleaning residues on the side walls and bottom to ensure efficient material discharge. The bottom end of scraper blade 11 is tightly attached to the bottom of the inner cavity of the mixing tank shell 1, pushing the material into discharge pipe 6 without any dead angles. Once the defoamer material in the mixing tank shell 1 is basically emptied, turn off motor 3 and turn on air pump 17. When the power is turned on and started, the air pump 17 draws in outside air and compresses it. The compressed air enters the annular air pipe 13 through the connecting pipe 15 and sprays airflow onto the inner wall of the discharge pipe 6 through the inclined nozzle 14. The airflow covers the entire inner wall of the discharge pipe 6, blowing away the adhering trace materials to the valve 16 for discharge. This ensures that the defoamer material adhering to the mixing tank shell 1 and the inner wall of the discharge pipe 6 can be cleaned in time, avoiding residue and greatly reducing resource waste. It also avoids the risk of cross-contamination.
[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
