[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a stirring device capable of defoaming, such as Figure 1-Figure 4 As shown, it includes a stirring shaft 1, a paddle 2 is symmetrically installed at the lower end of the stirring shaft 1, and a bubble scraper 3 is symmetrically installed at the upper end of the stirring shaft 1 for scraping the foam to concentrate it together. A plurality of bubble scraper blades 31 are vertically installed on the side of the bubble scraper 3 to scrape off and poke the foam on the water surface to achieve a defoaming effect. A plurality of bubble poking needles 311 are installed on the top of the bubble scraper blade 31 to poke the foam. A cavity is provided inside the stirring shaft 1, and a height adjustment component is installed in the cavity. The bubble scraper 3 is height-adjusted by the height adjustment component to achieve height adjustment of the bubble scraper 3, which can be flexibly adjusted according to the height of the foam on the water surface.

[0023] In this embodiment, the top end of the stirring shaft 1 is driven to rotate by the driving motor 4 , so as to facilitate the flexible rotation of the stirring shaft 1 .

[0024] Specifically, the foam scraping blades 31 are arranged in parallel and at equal intervals to ensure uniform scraping of the foam.

[0025] Furthermore, the height adjustment component includes a screw rod 12, on which a screw slider 13 is installed, guide holes 11 are provided on both sides of the stirring shaft 1, one end of the bubble scraper plate 3 passes through the guide hole 11 and is connected to the screw slider 13, and the top end of the screw rod 12 is driven to rotate by a screw motor 14, and the screw motor 14 drives the screw rod 12 to rotate, thereby realizing the lifting and lowering of the screw slider 13, and then driving the lifting and lowering of the bubble scraper plate 3.

[0026] Furthermore, a threaded joint 32 is installed at one end of the bubble scraper plate 3 , a threaded groove 131 is provided on the outer side of the screw slider 13 , and the threaded joint 32 is threadedly connected to the threaded groove 131 , which facilitates the installation and disassembly of the bubble scraper plate 3 .

[0027] Furthermore, a mounting plate 312 is welded to the bottom end of the bubble scraping blade 31 , and the mounting plate 312 is fixed to the bubble scraping plate 3 by bolts, so as to facilitate the installation and removal of the bubble scraping blade 31 .

[0028] Furthermore, a water passage 313 is provided in the middle of the bubble scraping blade 31, and a water inlet and a water outlet are respectively provided at the upper and lower ends of the water passage 313. The water inlet is located at the top of the bubble scraping blade 31, and the water outlet is located at the lower end side of the bubble scraping blade 31, so as to facilitate the passage of water and reduce the resistance of the bubble scraping plate 3. The water flow can also clean the bubble scraping blade 31.

[0029] Furthermore, the bottom end of the screw rod 12 is rotatably connected to the bottom of the cavity of the stirring shaft 1 through a bearing, thereby ensuring that the screw rod 12 rotates stably.

[0030] When the defoaming stirring device of the utility model is used, firstly, the core component of the whole device is the stirring shaft 1, and the lower end of the stirring shaft is symmetrically provided with blades 2 for stirring the liquid. When the driving motor 4 is started, it drives the stirring shaft 1 to rotate flexibly, thereby realizing the stirring function.

[0031] During the stirring process, a large amount of foam may be generated on the liquid surface due to certain chemical reactions or components in the liquid. In order to eliminate these foams, a foam scraper plate 3 is symmetrically installed on the upper end of the stirring shaft 1. When the stirring shaft 1 rotates, the foam scraper plate 3 will also rotate accordingly, scraping the foam on the liquid surface and gathering it together. A number of foam scraper blades 31 are vertically installed on the side of the foam scraper plate 3, and these blades are arranged in parallel and at equal intervals to ensure that the foam can be scraped evenly. When the foam scraper plate 3 rotates, the foam scraper blades 31 will scrape the foam on the water surface and further puncture it, thereby achieving a defoaming effect.

[0032] In order to enhance the defoaming effect, a plurality of bubble poking needles 311 are also installed on the top of the bubble scraping blade 31. These needle-like structures can more effectively poke the foam. Considering that the height of the foam may be different in different situations, a height adjustment component is also designed in the device. This component includes a screw 12 and a screw slider 13. When the height of the bubble scraping plate 3 needs to be adjusted, the screw motor 14 will drive the screw 12 to rotate, thereby driving the screw slider 13 to move up and down along the screw 12. Since one end of the bubble scraping plate 3 is connected to the screw slider 13 through the guide hole 11, the height of the bubble scraping plate 3 will also be adjusted accordingly. This design allows the device to be flexibly adjusted according to the height of the foam on the water surface to achieve the best defoaming effect.

[0033] During the scraping process, a water passage 313 is provided in the middle of the scraping blade 31, and the water flow is allowed to pass through. Such a design not only reduces the resistance of the scraping plate 3 during the rotation process, but also enables the water flow to pass through the scraping blade 31 and clean it, thereby keeping the blade clean and sharp.

[0034] Finally, it should be noted that the electronic components of the screw motor 14, drive motor 4, etc. in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.
