Description

Technical Field

[0001] The utility model belongs to the technical field of cylindrical mixers, and particularly relates to an on-line cleaning device for sticky materials and ring formation of a cylindrical mixer. Background Art

[0002] The cylindrical mixer is a key equipment in the sintering process of the iron and steel industry. Its function is to fully mix the iron-containing raw materials, fuels, solvents, etc. used in the sintering process, add water for wetting, and manufacture pellet balls, etc., so as to obtain a sintering mixture with uniform chemical composition and appropriate particle size. Adding solvents such as quicklime to the mixture is to strengthen the sintering process and improve the sintering production quality. However, after adding solvents such as quicklime, the mixture has too high viscosity, resulting in serious sticky materials and ring formation inside the cylinder body of the cylindrical mixer. If the inner wall of the cylinder body of the cylindrical mixer is sticky with materials and forms rings for a long time, it will inevitably increase the load weight of the cylinder body of the cylindrical mixer and the motor load, increase the power consumption and energy consumption. In addition, the sticky materials and ring formation on the inner wall of the cylinder body of the cylindrical mixer reduce the internal space of the cylinder body, change the mixing and rolling path of the materials, shorten the mixing time, reduce the mixing and granulation effects of the cylindrical mixer, and seriously affect the quality of sintered ore. The traditional method for cleaning the sticky materials and ring formation inside the cylinder body of the cylindrical mixer is generally manual cleaning at regular intervals, which is time-consuming and laborious. Moreover, during the cleaning process, large pieces of materials are likely to fall and injure people, resulting in frequent industrial accidents and endangering the lives of workers.

[0003] To overcome the above defects, the purpose of the utility model is to provide an on-line cleaning device for sticky materials and ring formation of a cylindrical mixer, which can conveniently and quickly clean the sticky materials and ring formation on the inner wall of the cylinder body of the cylindrical mixer on-line without stopping production.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] An on-line cleaning device for sticky materials and ring formation of a cylindrical mixer includes a cylinder body, a first support beam, a second support beam, a support, a tool rest and a scraper.

The other end of the first support beam extends outside the cylinder body and is fixedly connected to the support, and the other end of the second support beam extends outside the cylinder body and is fixedly connected to the foundation of the cylindrical mixer. The tool rest is arranged on one side of the first support beam and the second support beam close to the lining plate of the inner wall of the cylinder body, and a plurality of scrapers are arranged on the tool rest, and the cutting edges of the scrapers are serrated.

[0006] Preferably, a plurality of scrapers are arranged on both the upper and lower end faces of the tool rest, and the cutting edges of the upper and lower two layers of scrapers are arranged in a staggered manner.

[0007] Preferably, the plurality of scrapers are arranged parallel to the generatrix direction of the cylinder body, and the distance between the cutting edge of the scraper and the lining plate of the inner wall of the cylinder body is 10 cm to 15 cm.

[0018] The following further illustrates the utility model in conjunction with some specific embodiments.

[0019] See Figures 1-4, An on-line cleaning device for adhesive material and ring formation on a cylindrical mixer, comprising a cylinder body 1, a first support beam 2, a second support beam 3, a support 4, a tool holder 5 and a scraper 6. The cylinder body 1 is inclined and rotatable. Dust covers are provided at both ends of the cylinder body 1 and are fixed on the foundation of the cylindrical mixer without affecting the rotation of the cylinder body 1. Feed inlets and discharge outlets are provided on the dust covers at both ends. The first support beam 2 and the second support beam 3 are steel structures welded by I-beams and steel plates, having good bending resistance. One end of the first support beam 2 and the second support beam 3 is fixedly connected by bolts and nuts, and the middle section is arranged inside the cylinder body 1 of the cylindrical mixer. The other end of the first support beam 2 penetrates through the dust cover and extends outside the cylinder body 1 and is fixed on the support 4. The other end of the second support beam 3 penetrates through the dust cover and extends outside the cylinder body 1 and is fixed on the foundation of the cylindrical mixer. A tool holder 5 is installed on one side of the first support beam 2 and the second support beam 3 close to the inner wall lining of the cylinder body. A number of scrapers 6 are provided on the tool holder 5. The cutting edge of the scraper 6 is serrated. Each scraper 6 has 5 cutting edges, and the tooth shape of the cutting edge is a triangular tooth shape with an included angle of 45°, which can reduce the scraping resistance.

[0020] Furthermore, a number of scrapers 6 are provided on both the upper and lower end faces of the tool holder 5. The cutting edges of the double-layer scrapers 6 are staggered. The protruding parts of the cutting edges of the upper-layer scrapers correspond to the concave parts of the cutting edges of the lower-layer scrapers, and the concave parts of the cutting edges of the upper-layer scrapers correspond to the protruding parts of the cutting edges of the lower-layer scrapers, which can clean the adhesive material and ring formation on the inner wall of the cylinder body of the cylindrical mixer more comprehensively, ensuring that there are no dead corners when the scrapers clean the adhesive material and ring formation on the inner wall of the cylinder body, and improving the cleaning effect.

[0021] Furthermore, a number of scrapers 6 are placed parallel to the generatrix of the cylinder body 1 of the cylindrical mixer inside the cylinder body 1 of the cylindrical mixer. The cutting edge of the scraper 6 is opposite to the rotation direction of the cylinder body 1 of the cylindrical mixer. The distance between the cutting edge of the scraper 6 and the inner wall lining of the cylinder body 1 of the cylindrical mixer is 10 cm to 15 cm, ensuring that the scraper 6 can efficiently clean the adhesive material and ring formation on the inner wall of the cylinder body without damaging the inner wall lining of the cylinder body 1 of the cylindrical mixer.

[0022] Even further, two rows of waist-shaped holes 7 are opened on the blade surface of the scraper 6, and two rows of light holes matching the waist-shaped holes 7 are opened on the tool holder 5. Bolts penetrate through the waist-shaped holes 7 and the light holes to fix the scraper 6 on the tool holder 5, and the distance between the cutting edge of the scraper 6 and the inner wall of the cylinder body 1 of the cylindrical mixer can be adjusted to ensure that the scraper 6 does not damage the inner wall lining of the cylinder body 1 of the cylindrical mixer.

[0023] Furthermore, a wear-resistant pad 8 is provided on the cutting edge surface of the scraper 6 to improve the wear resistance of the scraper 6 and extend the service life of the scraper 6.

[0024] When the on-line cleaning device for adhesive material and ring formation on the cylindrical mixer of the present utility model is in use, during the rotation of the cylinder body 1, the adhesive material and ring formation on the inner wall of the cylinder body 1 of the cylindrical mixer are scraped off by the scraper 6, realizing the on-line scraping and cleaning of the adhesive material and ring formation. The structure is simple, reducing the labor intensity of workers, reducing the operating load of the motor, and significantly improving the quality of sintered ore.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
