Common powder classifiers include cyclone powder classifiers, three-separation powder classifiers, centrifugal powder classifiers, coal mill powder classifiers, calcium powder classifiers, etc. Later, many high-efficiency powder classifiers and high-efficiency three-separation powder classifiers were developed. They are new generation varieties that improve deficiencies and increase production on the basis of the original ones.

[0003] The three-separation powder concentrator breaks through the conventional closed-circuit grinding system's "coarse and fine powder" two-separation theory, and "divides" the material into three parts, namely coarse powder, medium coarse powder and fine powder. The product system has simple configuration and low cost, and can greatly increase the mill output. Its internal structure is reasonable and the powder selection effect is significant. It is the first choice product for improving the product quality of the grinding system after the implementation of the new cement standard.

[0004] When the existing powder classifier is separating large quantities of materials, if a large amount of material enters at a time, the amount of material entering the spreading equipment will increase, which will easily lead to a decrease in the dispersion effect of the spreading equipment, and then affect the powder selection, resulting in a higher content of fine powder in the coarse powder.

[0013] By providing a grinding heat conduction module, the grinding heat conduction module can transfer the heat generated by grinding to the heat conduction plate through the grinding seat when in use, and then heat the heat conduction ring pipe.

At this time, the drive motor drives the spreading seat to rotate for spreading operation. At the same time, the dispersion motor is started, and the dispersion motor drives the outer gear ring and the inner gear ring to rotate through the drive gear, and drives the dispersion rod to assist in spreading;

[0016] Step 2: The spreading seat operates to throw out the coarse powder, so that the coarse powder contacts the elastic material selection plate, loses power after contact and falls to the bottom of the separation bin, and the coarse powder is discharged and returned to the external device roller machine;

[0017] Step 3: While the coarse powder is being selected, ventilation is conducted to the interior of the separation bin through the tuyere pipe, so that the fine powder and medium powder scattered during the selection are driven by the wind to rise into the rectifier rotor, and the cyclone is started to collect the fine powder product, while the medium powder enters the inside of the dividing cone;

[0018] Step 4: After the medium powder enters the dividing cone, it enters the hollow cavity and the medium powder pipe through the through hole.

At this time, with the internal wind force rising and the grinding operation, the grinding heat is transferred to the inside of the heat conduction ring pipe through the heat conduction plate. The wind enters it to absorb the heat and discharge it, and when discharged, the fine powder and medium powder during the spreading operation are transported upward. The other feeding pipe returns part of the medium powder and coarse powder to the external equipment roller machine.

The movable gear 810 is located inside the mounting groove, and the driving gear 810 is meshed with the outer gear ring 817 and the inner gear ring 818; the outer wall of the hollow column seat 805 is provided with a plurality of fixing openings, and the inner walls of the plurality of fixing openings are provided with lifting plates 806, and the bottoms of the plurality of lifting plates 806 are fixedly connected with connecting wires 804, and one end of the plurality of connecting wires 804 is respectively fixedly connected with the outer walls of one side of the plurality of buffer plates 819, and an active cavity is provided inside the driving rod 11, and a pressure spring 814 is fixedly connected to the bottom of the inner wall of the active cavity, and a connecting plate 813 is fixedly connected to the top of the pressure spring 814, and the connecting plate 813 A plurality of connecting wires 807 are fixedly connected to the bottom, and one ends of the plurality of connecting wires 807 are respectively fixedly connected to the tops of the plurality of lifting plates 806; a plurality of material spreading openings 808 are equidistantly provided on the top of the hollow column seat 805, and a plurality of interconnected through holes are equidistantly provided on the inner walls of the plurality of material spreading openings 808 and the outer wall of the material dividing cone 12; the plurality of connecting wires 807 are respectively located inside the plurality of through holes, and a plurality of interconnected through holes 13 are equidistantly provided on the inner wall of one side of the material dividing cone 12 and the outer wall of the hollow column seat 805; a hollow cavity is provided at the bottom of the hollow column seat 805, and the plurality of through holes 13 are all connected to the hollow cavity.

[0035] Specifically, the material enters the separation bin 3, the drive motor 6 is started, and the drive motor 6 drives the drive rod 11 to rotate, so that the drive rod 11 drives the hollow column seat 805, the material distribution cone 12, the rectifier rotor 7 and the grinding roller equipment body 14 to rotate. At this time, the material contacts the buffer plate 819 through the material spreading port 808 to prevent the material from being directly scattered out of the material spreading seat 801. At the same time, the buffer plate 819 can drive the torsion spring 812 to rotate, so that the connecting line 1 804 is loosened. At this time, the pressure spring 814 drives the connecting plate 813 and the connecting line 2 807 to rise, and the material is put into the separation bin 3. The lifting plate 806 is pulled, and then the torsion spring 812 drives the buffer plate 819 to reset, and the connecting line 804 pulls the lifting plate 806 to reset, so that the material is lifted and vibrated and dispersed. When the material falls on the spreading seat 801, the dispersion motor 809 is started, and the dispersion motor 809 drives the driving gear 810 to rotate. Since the driving gear 810 is meshed with the outer gear ring 817 and the inner gear ring 818, the outer gear ring 817 and the inner gear ring 818 are driven to rotate, and then the dispersion rod 816 is driven to rotate, so that the material is evenly distributed, and then rotates through the spreading hole 803 for material selection;

[0036] In specific application scenarios, the scattering and anti-blocking accessory 8 is suitable for the coarse and heavy particle selection link, that is, the scattering and anti-blocking accessory 8 can make the material entering the scattering seat 801 for scattering and selection more evenly distributed when in use, thereby avoiding the material from being scattered in clumps during scattering, and further avoiding excessive internal fine powder content during coarse powder selection, so as to improve the use effect of the device.

[0038] Specifically, after the material is scattered, the coarse powder contacts the elastic material selection plate 1007 due to the centrifugal force. At this time, the elastic material selection plate 1007 transmits the impact force, so that the buffer spring 1005 absorbs the impact force and buffers it. At the same time, the elastic material selection plate 1007 can contact the sound-absorbing sponge column 1006 during buffering to reduce noise. In the process of spreading the material, the electric telescopic rod 1001 drives the material selection frame 1002 to move up and down to avoid the material from contacting a single position of the elastic material selection plate 1007 for a long time. At this time, the coarse powder loses power and falls;

[0039] In a specific application scenario, the material selection protection accessory 10 is suitable for the coarse powder selection link, that is, the material selection protection accessory 10 can buffer and protect the impact force generated by the coarse powder being thrown out during use, thereby avoiding wear and damage to the inner wall of the separation bin 3 after long-term material selection, so as to increase the service life of the device, and when the material is thrown out and impacted, the elastic material selection plate 1007 can contact with the sound-absorbing sponge column 1006, thereby transmitting and absorbing the sound generated by the impact, so as to reduce the noise generated by the use of the equipment and increase the practicality of the device.

[0040] Reference Figure 2 , Figure 8 and Fig. 9 In a preferred embodiment, the grinding heat conduction module 9 includes a grinding seat 901, the grinding seat 901 is fixedly connected to the inner wall of the separation chamber 3, and the inner wall of the grinding seat 901 is provided with a plurality of heat conduction plates 905 at equal distances, and the outer walls of one side of the plurality of heat conduction plates 905 are provided with mounting ports 906 and two air holes 904, and the inner walls of the plurality of mounting ports 906 are fixedly connected with the same heat conduction ring pipe 907, and the top of the heat conduction ring pipe 907 is provided with a plurality of exhaust ports 908 at equal distances; the bottom of the heat conduction ring pipe 907 is provided with a plurality of exhaust ports 908 at equal distances; A plurality of gas heat pipes 902 are equidistantly arranged at the bottom, and the input ends of the plurality of gas heat pipes 902 are fixedly connected with guide plates 903, and a grinding roller equipment body 14 is arranged at the bottom of the spreading seat 801, and the outer wall of the grinding roller equipment body 14 is in contact with the inner wall of the grinding seat 901, and a middle powder pipe 16 is fixedly connected to the bottom of the spreading seat 801, and the interior of the middle powder pipe 16 is connected with the hollow cavity, and three feed pipes 15 are fixedly connected to the outer wall of the hollow pipe, and one of the feed pipes 15 is located inside the heat-conducting ring pipe 907.

[0041] Specifically, after the medium powder enters the dividing cone 12, it enters the hollow cavity and the medium powder pipe 16 through the through hole 13. At this time, the medium powder is transported to the grinding seat 901 through two of the feeding pipes 15, and the grinding roller equipment body 14 is driven by the driving motor 6 to perform the grinding operation. At the same time, the wind drives the airflow to enter the guide plate 903, and then enters the gas heat pipe 902 through the guide plate 903. At this time, the heat generated during the grinding operation can be transferred to the heat conduction ring pipe 907 through the heat conduction plate 905, and the airflow inside the gas heat pipe 902 then enters the heat conduction ring pipe 907, and absorbs the heat transferred to the heat conduction ring pipe 907, and is discharged through the exhaust port 908 for cooling. At the same time, the discharged airflow passes through the material spreading area, and transports the medium powder and fine powder inside the material upward to the inside of the rectifier rotor 7;

[0042] In a specific application scenario, the grinding heat conduction module 9 is used in the medium powder grinding stage, that is, the grinding heat conduction module 9 can transfer the heat generated by grinding to the heat conduction plate 905 through the grinding seat 901 when in use, and then heat the heat conduction ring tube 907. At this time, the wind force inside the equipment moves through the guide plate 903 into the heat conduction ring tube 907 to reduce its internal temperature, thereby cooling the grinding seat 901 to ensure the use effect of the equipment. At the same time, the airflow density that absorbs heat is lower than the bottom airflow temperature, so that the airflow rises rapidly, so as to improve the rising effect of the internal fine powder and medium powder during coarse powder selection, and improve the powder selection quality.

[0043] A method for using a three-separation process powder selection device, using the three-separation process powder selection device as described above, comprises the following steps:

[0044] Step 1: The material enters the separation bin 3 through the feed pipe 5, and the drive motor 6 is started. The drive motor 6 drives the drive rod 11 to rotate, and then the drive rod 11 drives the hollow column seat 805, the material distribution cone 12, the rectifier rotor 7 and the grinding roller equipment body 14 to rotate. At this time, the material contacts the buffer plate 819 through the material spreading port 808 to prevent the material from being directly scattered out of the material spreading seat 801. At the same time, the buffer plate 819 can drive the torsion spring 812 and rotate, so that the connecting line 1 804 is loose, and the pressure spring 814 drives the connecting plate 813 and the connecting line 2 807 to rise. , and then pull the lifting plate 806, and then the torsion spring 812 drives the buffer plate 819 to reset, and the connecting line 804 pulls the lifting plate 806 to reset, so that the material is lifted and vibrated and dispersed. When the material falls on the spreading seat 801, the dispersion motor 809 is started, and the dispersion motor 809 drives the driving gear 810 to rotate. Since the driving gear 810 is engaged with the outer gear ring 817 and the inner gear ring 818, the outer gear ring 817 and the inner gear ring 818 are driven to rotate, and then the dispersion rod 816 is driven to rotate, so that the material is evenly distributed, and then rotates through the spreading hole 803 for material selection;

[0045] Step 2: After the material is scattered, the coarse powder contacts the elastic material selection plate 1007 due to centrifugal force. At this time, the elastic material selection plate 1007 transmits the impact force, so that the buffer spring 1005 absorbs and buffers the impact force. At the same time, the elastic material selection plate 1007 can contact the sound-absorbing sponge column 1006 during buffering to reduce noise. In the process of spreading the material, the electric telescopic rod 1001 drives the material selection frame 1002 to move up and down to prevent the material from contacting the elastic material selection plate 1007 at a single position for a long time. At this time, the coarse powder loses power to fall, and the coarse powder is discharged and returned to the external equipment roller machine;

[0046] Step 3: While the coarse powder is being selected, ventilation is conducted to the interior of the separation bin 3 through the tuyere pipe 2, so that the fine powder and medium powder scattered during the selection are driven by the wind to rise into the rectifier rotor 7, and the cyclone 4 is started to collect the fine powder product, while the medium powder enters the inside of the dividing cone 12;

[0047] Step 4, after the medium powder enters the dividing cone 12, it enters the hollow cavity and the medium powder connecting pipe 16 through the through hole 13. At this time, the medium powder is transported to the grinding seat 901 through two of the conveying pipes 15, and the grinding roller equipment body 14 is driven by the driving motor 6 to perform the grinding operation. At the same time, the wind drives the airflow to enter the guide plate 903, and then enters the gas heat pipe 902 through the guide plate 903. At this time, the heat generated during the grinding operation can be transferred to the inside of the heat conducting ring pipe 907 through the heat conducting plate 905, and the airflow inside the gas heat pipe 902 enters the inside of the heat conducting ring pipe 907, and absorbs the heat transferred to the inside of the heat conducting ring pipe 907, and is discharged through the exhaust port 908 for cooling. At the same time, the discharged airflow passes through the material spreading area, and transports the medium powder and fine powder inside the material upward to the inside of the rectifier rotor 7. The other conveying pipe 15 returns part of the medium powder and coarse powder to the external equipment roller machine.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
