Description

Technical Field

[0001] This utility model relates to the field of sodium silicate processing technology, and in particular to a sodium silicate stirring device. Background Technology

[0002] Sodium silicate, also known as sodium silicate aqueous solution or water glass, is an inorganic compound with the chemical formula Na₂SiO₃. It is a transparent to slightly turbid liquid with viscosity, and it gradually hardens into a gel-like substance in air. The production of sodium silicate requires mixing and stirring the raw materials to obtain liquid sodium silicate.

[0003] During the stirring process, a large number of bubbles are generated, which affects the quality of the final product. Existing methods mostly involve controlling the stirring speed or using a closed container to control the amount of bubbles. However, the bubbles still remain in the stirring container and are difficult to expel. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] See attached document Figures 1-4 A sodium silicate stirring device includes a stirring tank 1, the stirring tank 1 is equipped with a stirring device, the stirring device includes a drive shaft 3 driven by a motor 2, a stirring blade 4 located inside the stirring tank 1 is installed on the drive shaft 3, and a degassing device 5 installed on the drive shaft 3 is provided inside the stirring tank 1.

[0019] The degassing device 5 includes a top plate 51 fixed on the drive shaft 3. The top plate 51 has several openings 52 at equal intervals. One end of a scraper 53 is hinged to the opening 52. The scraper 53 is inclined. The mixing tank 1 includes an arc-shaped frame 54 located above the stirring blade 4. The top plate 51 is slidably mounted on the arc-shaped frame 54. An arc-shaped ramp 55 fixed inside the mixing tank 1 is provided below the arc-shaped frame 54. Auxiliary wheels 56 are rotatably mounted on both sides of the other end of the scraper 53. The auxiliary wheels 56 are in contact with the arc-shaped ramp 55.

[0020] The mixing tank 1 is equipped with a feed pipe 8 that is connected to the mixing tank 1. The feed pipe 8 is located between the mixing blades 4 and the top plate 51.

[0021] The mixing tank 1 is divided into two parts by the top plate 51. The lower part is the traditional mixing area, where the raw materials enter the mixing tank 1 and are mixed by the mixing blades 4. The upper part of the top plate 51 is the degassing area, where air bubbles are scraped into the degassing area by the scraper 53.

[0022] Specifically, the starting motor 2 drives the stirring blades 4 to stir the raw materials. During stirring, bubbles are generated and float on the surface of the raw materials, located at the arc-shaped frame 54. The rotation of the drive shaft 3 causes the top plate 51 to rotate, which in turn causes the scraper 53 to rotate. The rotating scraper 53 comes into contact with the bubbles and scrapes them onto it. As the scraper 53 continues to rotate, when it reaches the arc-shaped slope 55, the auxiliary wheel 56 comes into contact with the surface of the arc-shaped slope 55 and moves on it. As the auxiliary wheel 56 continues to move on the arc-shaped slope 55, which is uphill, the scraper 53 is lifted and moved towards the top plate 51 during rotation, finally causing the bubbles to enter the degassing area.

[0023] In this embodiment, as Figure 4 As shown, a discharge assembly 7 is provided above the top plate 51. The discharge assembly 7 includes a drive gear 71 fixed on the drive shaft 3, and a seat 72 fixed on the top of the mixing tank 1. A gear sleeve 73 that meshes with the drive gear 71 is rotatably mounted on the seat 72. An auxiliary scraper 74 is installed at the bottom of the gear sleeve 73.

[0024] In summary, as the scraper 53 is continuously raised, it will completely enter the opening 52, making the scraper 53 and the top plate 51 flush, allowing the air bubbles to completely enter the degassing area.

[0025] At the same time, the rotation of the drive shaft 3 will drive the drive gear 71 to rotate, which will mesh with the gear sleeve 73 to rotate. The rotation of the gear sleeve 73 can drive the auxiliary scraper 74 to rotate. The rotation of the auxiliary scraper 74 can scrape off the air bubbles on the scraper 53. After scraping, the auxiliary wheel 56 will move to the end on the arc-shaped ramp 55. Finally, as the scraper 53 continues to rotate, the auxiliary wheel 56 passes through the arc-shaped ramp 55 and falls, causing the scraper 53 to fall due to gravity and form an inclined shape again, so that it can continue to scrape off the air bubbles.

[0026] It should be noted that, in order to avoid the auxiliary scraper 74 and the top plate 51 moving synchronously and failing to achieve the scraping effect, the rotation speed of the auxiliary scraper 74 will be less than that of the top plate 51. Specifically, since the top plate 51 is mounted on the drive shaft 3, the rotation speed of the top plate 51 is the same as that of the drive shaft 3. The drive gear 71 is also mounted on the drive shaft 3, so their rotation speeds are the same. However, the diameter of the drive gear 71 is smaller than the diameter of the gear sleeve 73, so the rotation speed of the gear sleeve 73 is less than that of the drive gear 71. As a result, the top plate 51 rotates faster and the auxiliary scraper 74 rotates slower. The two do not move synchronously, resulting in a speed difference. Thus, the auxiliary scraper 74 can scrape away the air bubbles through the opening 52.

[0027] In addition, such as Figure 2 As shown, a collection box 6 is fixed around the mixing tank 1. The collection box 6 is connected to the top of the mixing tank 1. The top of the collection box 6 has a box opening 61 and a box cover 62.

[0028] After the air bubbles on scraper 53 are scraped off by auxiliary scraper 74, the air bubbles will be thrown into collection box 6 by centrifugal force as auxiliary scraper 74 rotates, so that the air bubbles can be collected. The collected air bubbles can be discharged by opening the box cover 62.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
