Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection material stirring, in particular to an environmental protection material stirring device. Background Art

[0002] Environmentally friendly materials refer to materials that are non-toxic, harmless, low-toxic and low-emission, or materials whose toxic substances cannot be determined and evaluated by scientific technology and testing methods. Popular environmentally friendly decorative materials on the market mainly include environmentally friendly wall materials, environmentally friendly wall decorations, environmentally friendly floor materials, environmentally friendly pipes, environmentally friendly paints, environmentally friendly lighting, etc. Among them, some viscous environmentally friendly materials need to be stirred and mixed during production.

[0003] The stirring structure in the traditional mixing box is simple. For the production of environmentally friendly coatings with viscous liquid mixtures, the stirring effect is not good, especially for the stirring and mixing of multiple materials. Due to the differences in specific gravity, particle size, etc. between the materials, stratification often occurs, that is, the material with a larger specific gravity is deposited at the bottom, and the material with a smaller specific gravity floats on the surface, which not only affects the stirring effect, but also may cause unstable product quality; secondly, the sticky attachments in the material will adhere to the inner wall. If it is cleaned after stirring, the residue on the inner wall is easy to harden and agglomerate, resulting in troublesome cleaning. If it is cleaned at the same time as stirring during the stirring process, the scraper and the stirring rod work simultaneously, resulting in unnecessary functional loss, which is not in line with the advocated concept of saving and environmental protection.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] like Figure 1-5 As shown, the utility model provides an environmentally friendly material stirring device, including a stirring barrel 1, a stirring mechanism 2 and a wall scraping mechanism 3;

[0030] A feed inlet is arranged at the top of the mixing barrel 1, and a discharge outlet is arranged at the bottom; the stirring mechanism 2 comprises a motor 21, a transmission assembly 22 and two stirring shafts 23, the two stirring shafts 23 are symmetrically and rotatably arranged at the top of the mixing barrel 1, and the two stirring shafts 23 are fixedly connected with a stirring auger 24 located in the mixing barrel 1, and the motor 21 realizes the simultaneous rotation of the two stirring shafts 23 through the transmission assembly 22, and the two stirring shafts 23 rotate in opposite directions and at different speeds; the wall scraping mechanism 3 comprises a wall scraping member 31 and a reduction assembly 32, the wall scraping member 31 is arranged in the mixing barrel 1, the wall scraping member 31 is a spiral belt scraper and fits the inner wall of the mixing barrel 1, and the motor 21 realizes the low-speed rotation of the wall scraping member 31 through the reduction assembly 32.

[0031] In this embodiment, the transmission assembly 22 includes a bracket 221 fixedly connected to the top of the mixing barrel 1, the motor 21 is installed on the bracket 221, and a transmission shaft 222, a first rotating shaft 223 and a second rotating shaft 224 are rotatably provided on the bracket 221. The output shaft of the motor 21 is fixedly connected to one end of the transmission shaft 222, a first transmission wheel 225 is fixedly sleeved on the transmission shaft 222, and a second transmission wheel 226 and a third transmission wheel 227 are fixedly sleeved on the first rotating shaft 223 and the second rotating shaft 224 respectively. A first transmission belt 228 is provided for transmission between the first transmission wheel 225 and the second transmission wheel 226, and a second transmission belt 229 is provided for transmission between the first transmission wheel 225 and the third transmission wheel 227.

[0032] Specifically, the motor 21 drives the transmission shaft 222, and drives the first rotating shaft 223 and the second rotating shaft 224 to rotate respectively through the first transmission wheel 225 via the first transmission belt 228 and the second transmission belt 229, so that the first rotating shaft 223 and the second rotating shaft 224 rotate simultaneously.

[0033] In this embodiment, the diameter of the second transmission wheel 226 is greater than the diameter of the first transmission wheel 225 , and the diameter of the third transmission wheel 227 is smaller than the diameter of the first transmission wheel 225 .

[0034] Specifically, since the diameters of the second transmission wheel 226, the first transmission wheel 225 and the third transmission wheel 227 are arranged from large to small, when the first transmission wheel 225 drives the first rotating shaft 223 and the second rotating shaft 224 to rotate respectively via the first transmission belt 228 and the second transmission belt 229, the rotation speed of the first rotating shaft 223 is lower than that of the transmission shaft 222, and the rotation speed of the second rotating shaft 224 is higher than that of the transmission shaft 222, thereby achieving different rotation speeds of the first rotating shaft 223 and the second rotating shaft 224.

[0035] In this embodiment, the first rotating shaft 223 and the second rotating shaft 224 are respectively fixedly sleeved with the first bevel gear 2210 and the second bevel gear 2211 , and the top ends of the two stirring shafts 23 are respectively fixedly connected with the third bevel gear 2212 and the fourth bevel gear 2213 that cooperate with the first bevel gear 2210 and the second bevel gear 2211 .

[0036] Specifically, when the first rotating shaft 223 and the second rotating shaft 224 rotate, they can respectively drive the first bevel gear 2210 and the second bevel gear 2211 to rotate, and respectively drive the two stirring shafts 23 to rotate in the opposite direction through the third bevel gear 2212 and the fourth bevel gear 2213, so that the two stirring shafts 23 have different rotation speeds and opposite directions. The reverse rotation of the two stirring shafts 23 produces convective shear, reduces material stratification, and the reverse rotation avoids material accumulation in the center of the barrel, thereby improving stirring uniformity.

[0037] In this embodiment, the wall scraping mechanism 3 further includes a support platform 33 fixedly connected to the mixing barrel 1 , a gear ring 34 is rotatably provided in the support platform 33 , and the wall scraping member 31 is fixedly connected to the bottom of the gear ring 34 .

[0038] Specifically, the support platform 33 provides support for the gear ring 34 , and the wall scraper 31 rotates with the mixing barrel 1 as the axis as the gear ring 34 rotates.

[0039] In this embodiment, the reduction assembly 32 includes a box body 321 fixedly connected to the outer wall of the mixing barrel 1, a linkage rod 322 is rotatably provided on the box body 321, one end of the linkage rod 322 is fixedly connected to the first rotating shaft 223, the other end of the linkage rod 322 extends into the box body 321 and is fixedly connected to a bevel gear 323, a vertical rod 324 perpendicular to the linkage rod 322 is rotatably provided in the box body 321, a bevel gear disk 325 meshing with the bevel gear 323 is fixedly sleeved on the vertical rod 324, a rotating tooth 326 located below the bevel gear disk 325 is fixedly sleeved on the vertical rod 324, and the rotating tooth 326 is meshed with the gear ring 34; the number of teeth of the bevel gear disk 325 is 5 times the number of teeth of the bevel gear 323, and the number of teeth of the gear ring 34 is 10 times the number of teeth of the rotating tooth 326.

[0040] Specifically, the first rotating shaft 223 drives the bevel gear 323 through the linkage rod 322, the bevel gear 323 meshes with the bevel gear disk 325 to drive the vertical rod 324, the rotating teeth 326 on the vertical rod 324 drive the gear ring 34, and then drives the scraper 31 to rotate at an extremely low speed, scraping continuously at a low speed to remove the material adhering to the barrel wall; the reduction ratio of the bevel gear 323 and the bevel gear disk 325 is 5:1, and the reduction ratio of the rotating teeth 326 and the gear ring 34 is 10:1. The multi-stage reduction reduces the scraping power to less than 5% of the main stirring, saving energy and reducing consumption.

[0041] In this embodiment, a wall scraping rod 35 is fixedly connected to the bottom of the wall scraping member 31 , and the wall scraping rod 35 is in contact with the inner bottom wall of the mixing barrel 1 .

[0042] Specifically, the scraping rod 35 follows the scraping member 31 to scrape the inner bottom wall of the mixing barrel 1 .

[0043] How to use and working principle of this device:

[0044] Environmentally friendly materials are put into the mixing barrel 1 through the feed port, and the motor 21 is started to drive the transmission shaft 222 to rotate. The transmission shaft 222 drives the first transmission wheel 225 and drives the second transmission wheel 226 and the third transmission wheel 227 to rotate through the first transmission belt 228 and the second transmission belt 229. The diameter of the second transmission wheel 226 is larger than that of the third transmission, so that the first rotating shaft 223 and the second rotating shaft 224 rotate at a higher and lower speed than the transmission shaft 222 respectively. The first rotating shaft 223 makes the corresponding stirring shaft 23 rotate counterclockwise at a low speed through the cooperation of the first bevel gear 2210 and the third bevel gear 2212, pushing the material to move upward. The second rotating shaft 224 makes the corresponding stirring shaft 23 rotate clockwise at a high speed through the cooperation of the second bevel gear 2211 and the fourth bevel gear 2213, generating a downward shear flow. The double speed difference of the two stirring shafts 23 forms a velocity gradient, generating a shear rate, and reverse rotation avoids the accumulation of the environmentally friendly material in the center. The stirring auger 24 pushes the environmentally friendly material to roll up and down and diffuse radially, thereby improving the mixing uniformity and achieving a better mixing effect.

[0045] During mixing, the first rotating shaft 223 with a relatively low rotation speed drives the linkage rod 322 to rotate the bevel gear 323, and the bevel gear 323 meshes with the bevel gear plate 325 to drive the vertical rod 324, and the rotating teeth 326 on the vertical rod 324 drive the gear ring 34, thereby driving the scraper 31 to rotate at an extremely low speed. The multi-stage reduction reduces the scraper power to less than 5% of the main stirring. During the stirring process, the scraper continuously scrapes at a low speed to remove the material adhering to the barrel wall, which can avoid the problems of low scraping and cleaning efficiency after stirring, easy hardening and agglomeration of residues, and large fluctuations in uniformity due to static stratification in the late stage of mixing, and can also avoid the problems of partial splashing, sharp increase in power consumption and large wear caused by high-speed scraping during stirring;

[0046] After the mixing is completed, the bottom discharge port is opened, the stirring auger 24 continues to rotate to push the material out, and the scraper mechanism 3 keeps running until there is no residue in the barrel, thereby reducing the residue in the stirring barrel 1.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
