Description

Technical Field

[0001] This utility model relates to the field of material crushing and processing technology, and in particular to a circulating fluid crusher. Background Technology

[0002] In modern industrial production, material crushing is a key pre-processing step in many processing stages. As various industries continuously raise their requirements for product quality, higher standards are being set for the particle size, uniformity, and production efficiency of crushed materials. Some existing crushing equipment uses only mechanical crushing or airflow crushing methods, which cannot fully utilize the advantages of both methods, resulting in low crushing efficiency and high energy consumption. The material screening device is also poorly designed and cannot efficiently screen out materials that meet the particle size requirements. The recycling and reprocessing efficiency of materials that do not meet the particle size requirements is low, making it impossible to achieve efficient recycling of materials and meet the needs of continuous production. Therefore, we have introduced a circulating fluid crusher. Utility Model Content

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A circulating fluid pulverizer includes an upper plate 1, with support rods 8 fixedly connected to the four corners of the lower end of the upper plate 1. The bottom of the four support rods 8 is fixedly connected to a base plate 9. A pulverizing box 5 is fixedly connected to the upper left part of the base plate 9. A pulverizing device 4 and an auxiliary device 6 are respectively fixedly installed on the upper left and lower left parts of the pulverizing box 5.

[0027] The crushing box 5 is fixedly connected to the middle of the right end of the No. 3 connecting pipe 13. The other end of the No. 3 connecting pipe 13 is fixedly connected to the filter device 7. The outer right side of the filter device 7 is fixedly connected to the No. 4 connecting pipe 14. The other end of the No. 4 connecting pipe 14 is connected to the blower device 15. The lower end of the filter device 7 is fixedly connected to the collection box 16. The lower left side of the upper plate 1 is fixedly connected to two fixing brackets 11. The left and right ends of the two fixing brackets 11 are fixedly connected to the screw feeder 3. The lower outer surface of the screw feeder 3 is fixedly connected to the No. 2 connecting pipe 12. The upper left side of the upper plate 1 is fixedly connected to the hopper 2. The lower end of the hopper 2 is fixedly connected to the No. 1 connecting pipe 10.

[0028] Four support rods 8 are fixed in a rectangular arrangement at the four corners of the lower end of the upper plate 1, and the support rods 8 are perpendicular to the upper plate 1 and the bottom plate 9.

[0029] In this embodiment, the crushing device 4 includes a drive motor 41. The output end of the drive motor 41 passes through the crushing box 5 and is fixedly connected to a rotating rod 43. A rotating outer cylinder shell 42 is fixedly connected to the outer surface of the rotating rod 43. A plurality of long grooves 44 are opened on the outer surface of the rotating outer cylinder shell 42. A plurality of crushing blades 45 are fixedly connected in each of the plurality of long grooves 44. The drive motor 41 is fixedly installed on the upper left side of the crushing box 5. The auxiliary device 6 includes a blower device 65. A long pipe 61 is fixedly connected to the output end of the blower device 65. A plurality of diverter pipes 62 are fixedly connected to the lower part of the outer surface of the long pipe 61. A high-pressure air inlet nozzle 64 is provided on the outer surface of each of the plurality of diverter pipes 62. A connecting frame 63 is fixedly connected to the upper part of the outer surface of the plurality of diverter pipes 62. The bottom of the blower device 65 is fixedly installed on the upper rear part of the base plate 9. The plurality of long grooves 44 are distributed in a ring at equal intervals around the rotating outer cylinder shell 42. The plurality of crushing blades 45 are all inclined at a 30-degree angle.

[0030] Through the above scheme: after the drive motor 41 starts, it drives the rotating rod 43 and the rotating outer cylinder shell 42 to rotate. In the annularly distributed long grooves 44 on the outer surface of the rotating outer cylinder shell 42, the crushing blades 45, which are inclined at a 30-degree angle, mechanically impact and shear the material. At the same time, the blower 65 compresses the air and sprays it into the crushing box 5 through the long pipe 61 and the diverter pipe 62, forming a high-speed, high-pressure airflow through the high-pressure air intake nozzle 64. This pushes the material to collide and rub against the crushing blades 45 and between the materials, thus achieving crushing. The combination of mechanical crushing and airflow crushing, the special angle of the crushing blades 45 and the distribution of the long grooves 44 enhance the crushing effect, and the high-speed airflow generated by the high-pressure air intake nozzle 64 ensures that the material is fully dispersed and collided, improving the crushing efficiency and quality, so that the equipment has a good crushing effect and high efficiency.

[0031] In this embodiment, the filtration device 7 includes an outer barrel 71 and a second drive motor 77. A barrel cover 75 is fixedly connected to the upper end of the outer barrel 71. The output end of the second drive motor 77 passes through the barrel cover 75 and is fixedly connected to a connecting rod 72. Several filter plates 76 are fixedly connected to the outer surface of the connecting rod 72. A conveying pipe 73 is fixedly connected to the bottom of the outer barrel 71. A switch valve 74 is provided on the outer surface of the conveying pipe 73. The outer barrel 71 is inserted and fixedly installed at the lower end of the upper plate 1. The left and right parts of the outer surface of the outer barrel 71 are fixedly installed to the third connecting pipe 13 and the fourth connecting pipe 14, respectively. The bottom of the conveying pipe 73 is fixedly installed to the surface of the collection box 16. Several filter plates 76 are distributed in a ring at equal intervals around the connecting rod 72. The outer barrel 71 communicates with the inside of the collection box 16 through the conveying pipe 73.

[0032] Through the above scheme: the crushed material enters the outer barrel 71 through the No. 3 connecting pipe 13. The drive motor 77 drives the connecting rod 72 and the annularly distributed filter plates 76 to rotate. The material impacts the filter plates 76. Those that meet the particle size requirements pass through the sieve holes and fall into the collection box 16 through the conveying pipe 73. Those that do not meet the requirements are intercepted and returned to the crushing box 5 for re-crushing under the suction generated by the blower equipment 15 through the No. 4 connecting pipe 14. The rotating filter plates 76 achieve dynamic and efficient screening, ensuring accurate particle size screening. It is linked with the crushing process to form a cycle, ensuring continuous material processing, improving crushing efficiency and product quality stability, and reducing manual intervention.

[0033] It should be noted that this utility model is a circulating fluid pulverizer. During the operation of the circulating fluid pulverizer, the material first starts from the hopper 2, passes through the first connecting pipe 10, and falls smoothly into the screw feeder 3 by gravity. The spiral blades inside the screw feeder 3 rotate at high speed under the drive of the motor. During the rotation, the material is pushed by the spiral blades and subjected to friction, moving slowly along the spiral trajectory of the spiral blades, gradually being conveyed from the feed end to the discharge end of the equipment, and finally being accurately fed into the pulverizing chamber 5 through the second connecting pipe 12. When the material enters the pulverizing chamber 5, the pulverizing device 4 immediately starts to operate. The drive motor 41 starts after the power is turned on, and the stator winding inside the motor generates a rotating magnetic field after being energized. The magnetic field interacts with the rotor windings, causing the rotor to generate electromagnetic torque, which in turn drives the motor output shaft to rotate at high speed. The rotation of the motor output shaft is transmitted to the rotating rod 43 through transmission components such as couplings. The rotating rod 43 drives the rotating outer cylinder shell 42, which is fixed to its outer surface, to rotate at high speed. Since several long grooves 44 are evenly distributed on the outer surface of the rotating outer cylinder shell 42, and several crushing blades 45 are fixedly connected in each long groove 44, these crushing blades 45, driven by the rotating outer cylinder shell 42, mechanically impact and shear the material in a high-speed rotation. At the same time, the auxiliary device 6 also starts to work. After the blower equipment 65 draws in the outside air, it compresses the air by the high-speed rotation of the internal impeller, so that the air obtains a higher temperature. The pressure energy is then used to deliver compressed air from the output end to the long pipe 61. As the compressed air flows through the long pipe 61, it is divided by several branch pipes 62. The divided compressed air then enters each branch pipe 62. Since each branch pipe 62 has a high-pressure air inlet nozzle 64 on its outer surface, the compressed air forms a high-speed, high-pressure airflow that is injected into the crushing chamber 5. This high-speed, high-pressure airflow comes into full contact with the material, generating a strong impact force. The material, carried by the airflow, collides and rubs against the crushing blades 45 and with each other, thus achieving efficient crushing. The crushed material, propelled by the continuous airflow generated by the blower 65, forms a material-carrying airflow within the crushing chamber 5. The material moves to the right end of the crushing box 5 and enters the filter device 7 through the third connecting pipe 13. After the drive motor 77 in the filter device 7 starts, the motor output shaft drives the connecting rod 72 to rotate at high speed. Several filter plates 76 fixedly connected to the outer surface of the connecting rod 72 rotate together. During the rotation, these filter plates 76 screen the material entering the filter device 7. Since the filter plates 76 are provided with screen holes of a specific size, when the material impacts the filter plates 76 under the action of airflow, the fine material particles that meet the particle size requirements can pass through the screen holes. Under the action of gravity, they fall into the collection box 16 for collection through the conveying pipe 73 at the bottom of the outer barrel 71. The larger particles that do not meet the particle size requirements are intercepted by the filter plates 76 and cannot pass through the screen holes.Larger particles intercepted by filter plate 76 are drawn back into the grinding chamber 5 by the suction force generated by blower 15. Since the right side of the outer surface of filter device 7 is connected to blower 15 via connecting pipe 14, the blower 15, through impeller rotation, draws air out of connecting pipe 14, creating a negative pressure environment. Under this negative pressure difference, the intercepted material is drawn back into connecting pipe 14 and returned to the grinding chamber 5. The material returning to the grinding chamber 5 is then pulverized again with newly entering material under the synergistic action of grinding device 4 and auxiliary device 6. This cycle repeats until all material reaches the required particle size.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
