Description

Technical Field

[0001] The utility model belongs to the technical field of stirrers, and particularly relates to a stirring scraper. Background Art

[0002] Conventional mixers, in the case of serious material sticking to the wall, will add a scraper structure on the anchor frame blade so that the material sticking to the wall can be scraped away by the rotating mixer scraper, and the material will not be compacted on the inner wall of the inner cylinder, thereby achieving an effective stirring and mixing effect. If the material sticking to the wall cannot be scraped away in time, it will be compacted on the inner wall of the inner cylinder, which will not only cause material waste, but also be difficult to clean because it is stuck to the cylinder wall. At present, conventional stirring scraper structures are either fixed scrapers or one-way scrapers.

[0003] For fixed scrapers, there may be some deviation in the inner diameter of the cylinder. The fixed scraper is fixedly connected to the inner wall of the cylinder and there is no adjustment margin. Therefore, there will be areas where the inner wall of the cylinder and the scraper fit loosely, and the inside of the cylinder wall cannot be scraped cleanly; and areas where the inner wall of the cylinder and the scraper fit tightly will seriously scratch the inner wall of the cylinder.

[0004] One-way scrapers can only scrape in one direction and are relatively simple to use. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a stirring scraper, which is a bidirectional scraper that can meet the actual needs of forward or reverse rotation, and has floating contact, fits closely with the inner wall of the cylinder without scratching the inner wall of the cylinder.

[0006] The utility model provides a stirring scraper, comprising:

[0007] A scraper connecting piece, wherein the scraper connecting piece is fixedly arranged on the stirring blade;

[0008] The scraper body is movably arranged on the scraper connecting piece, and the scraper body can swing left and right relative to the stirring blade.

[0009] Furthermore, the scraper connecting piece includes:

[0010] An installation limit plate is fixedly arranged on the stirring blade, and there are two installation limit plates, which are spaced apart from each other;

[0011] The mounting portion is arranged on the scraper body and is arranged between the upper and lower mounting limit plates.

[0012] Furthermore, the upper and lower mounting limit plates are both provided with through holes, and a cylindrical pin is provided inside the mounting portion and along its length direction. The upper and lower ends of the cylindrical pin respectively pass through the mounting portion, and the scraper body is limited in the upper and lower directions by inserting the upper and lower ends of the cylindrical pin into the corresponding through holes.

[0013] Furthermore, the upper and lower ends of the cylindrical pin respectively pass through corresponding through holes, and the upper and lower ends of the cylindrical pin are both provided with a locking pin to prevent the cylindrical pin from falling off from the through hole of the mounting limit plate.

[0014] Furthermore, the bayonet pin is a wavy hairpin pin.

[0015] Furthermore, the scraper body is a triangular prism structure.

[0016] Furthermore, the scraper body is an isosceles triangular prism structure, and the isosceles surface is the stirring slurry contact surface.

[0017] The beneficial effects of the utility model are:

[0018] The scraper used in this utility model is a bidirectional scraper, which can meet the actual needs of forward or reverse rotation. It has floating contact and fits closely with the inner wall of the cylinder without scratching the inner wall. When the stirring is unidirectional, if one side of the scraper is worn and no longer contacts the inner wall of the cylinder, the scraper can be removed, rotated 180 degrees, and then reinstalled to meet the same scraping requirements. Therefore, the replacement cycle of this scraper is twice that of a unidirectional scraper, and the service life is long.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0027] like Figures 1 to 3 The figure shows the optimal embodiment of the present invention. The present invention provides a stirring scraper, comprising: a scraper connector and a scraper body 1.

[0028] The scraper connecting piece is fixedly arranged on the stirring blade 10 , and the scraper body 1 is movably arranged on the scraper connecting piece. The scraper body 1 can swing left and right relative to the stirring blade 10 .

[0029] The stirring scraper of the utility model can swing in the direction of the flow of the slurry under the impact of the stirring slurry, and can meet the needs of forward or reverse rotation. The scraper body 1 is movably arranged on the scraper connecting piece. The scraper body 1 is in floating contact with the inner wall of the cylinder under the push of the slurry. Therefore, the scraper body 1 fits closely with the inner wall of the cylinder and will not scratch the inner wall of the cylinder.

[0030] The scraper connection includes: a mounting limit plate 2 and a mounting portion 3. The mounting limit plate 2 is fixedly mounted on the stirring blade 10. The mounting limit plate 2 is two pieces, and the two mounting limit plates 2 are spaced apart. The mounting portion 3 is mounted on the scraper body 1, and the mounting portion 3 is positioned between the upper and lower mounting limit plates 2. The mounting limit plate 2 and the outermost side of the stirring blade 10 are fixed together by welding. They can be arranged according to actual needs to ensure that every part of the mixing operation area can be scraped cleanly.

[0031] Both the upper and lower mounting limit plates 2 are provided with through holes. A cylindrical pin 4 is provided within the mounting portion 3 and along its length. The upper and lower ends of the cylindrical pin 4 extend through the mounting portion 3, respectively. By inserting the upper and lower ends of the cylindrical pin 4 into the corresponding through holes, the scraper body 1 is limited in the vertical direction. The cylindrical pin 4 and the mounting limit plate 2 are fitted with a clearance fit, thereby ensuring that the cylindrical pin 4 can freely swing left and right along the mounting limit plate 2, thereby driving the scraper body 1 to automatically swing left and right. The magnitude of the swing depends on the limit of the mounting limit plate 2 on the slurry contact surface 6.

[0032] The upper and lower ends of the cylindrical pin 4 pass through corresponding through holes respectively, and the upper and lower ends of the cylindrical pin 4 are both provided with a locking pin to prevent the cylindrical pin 4 from falling off from the through hole of the mounting limit plate 2.

[0033] The locking pin is a wavy hairpin pin 5, and the wavy hairpin pin 5 is installed to the end of the cylindrical pin 4, specifically including: opening the wavy hairpin pin 5 by external force, inserting its smooth end into the end of the cylindrical pin 4, and making the wavy part tightly against the outer periphery of the cylindrical pin 4 through its own elasticity, so that the cylindrical pin 4 is not easy to disengage from the installation limit plate 2. At the same time, the surface of the wavy hairpin pin 5 is smooth and has no threads, which is easier to clean.

[0034] The scraper body 1 is a triangular prism structure, preferably an isosceles triangular prism structure, and the isosceles surface is the mixing slurry abutment surface 6. When the mixed slurry flows, the impact force hits the slurry abutment surface 6, causing the scraper body 1 to abut against the inner wall of the cylinder, scraping off the adhered matter on the inner wall of the cylinder.

[0035] Working principle:

[0036] like Figure 3 As shown, the scraper body 1 is fixed to the outermost side of the anchor frame stirring blade 10. When the stirring shaft rotates, it drives the slurry to flow. The impact force of the slurry flow hits the slurry contact surface 6, causing the scraper body 1 to contact the inner wall of the cylinder, scraping away any adherent matter on the inner wall of the cylinder. The contact tightness between the scraper body 1 and the inner wall of the cylinder is adjustable, thus acting as a floating scraper. The scraper is composed of mechanical parts with a smooth surface and no threads, making it easy to clean and leaving no slurry residue.

[0037] In summary, the scraper used in this utility model is a bidirectional scraper that can meet the actual needs of forward or reverse rotation. It also has floating contact, which makes it fit closely with the inner wall of the cylinder without scratching the inner wall. When the stirring is unidirectional, if one side of the scraper is worn and no longer contacts the inner wall of the cylinder, the scraper can be removed, rotated 180 degrees, and then reinstalled to meet the same scraping requirements. Therefore, the replacement cycle of this scraper is twice that of a unidirectional scraper, and the service life is long.
