Description

Technical Field

[0001] This utility model relates to crushing equipment, specifically a three-axis crusher. Background Technology

[0002] Currently, domestic enterprises need to use pulverizing equipment when producing iron oxide red. Conventional pulverizing equipment usually consists of multiple pulverizers. After multiple pulverizations, qualified powder is obtained. Between each pulverizer, the product from the previous step needs to be transported manually to the next step for the next process. In this case, the labor intensity of workers is very high, especially in summer, when employees are prone to heatstroke. At the same time, a large amount of dust is generated during the transportation process, which not only has a negative impact on the environment and the health of workers, but also inevitably introduces impurities. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a three-axis crusher, which effectively solves the problems pointed out in the background art.

[0004] The technical solution adopted in this utility model is:

[0005] A three-axis crusher includes a hopper, and a first crushing device, a transverse conveying device, and a second crushing device arranged sequentially from top to bottom within the hopper. The first crushing device, the transverse conveying device, and the second crushing device are all driven by a motor, and the bottom of the hopper is the hopper outlet.

[0006] Preferably, the first crushing device includes a first crushing chamber fixed inside the hopper and a first crushing shaft arranged horizontally at the center of the first crushing chamber. The inner wall of the first crushing chamber is provided with a plurality of first crushing rods along the axial direction. The first crushing rods are fixed to the first crushing shaft by rotating disks at both ends. The top of the first crushing chamber is provided with a first feed inlet and the side is provided with a first discharge outlet. A first screen is fixed on the first discharge outlet.

[0007] The first crushing device is used for initial crushing to obtain products with larger particles. At the same time, the first screen uses a thicker wire diameter to solve the problem of frequent screen breakage in the original single-layer screen, thus ensuring product quality (no impurities). The position of the first crushing rod in the radial direction of the first crushing shaft can be adjusted as needed. When the distance between the first crushing rod and the first crushing shaft is large, that is, the gap between the first crushing rod and the inner wall of the first crushing chamber is small, the crushed product particles are relatively small. When the distance between the first crushing rod and the first crushing shaft is small, that is, the gap between the first crushing rod and the inner wall of the first crushing chamber is large, the crushed product particles are relatively large.

[0008] Preferably, the transverse conveying device includes a conveying bin with an opening at the top and a spiral conveying mechanism arranged transversely at the center of the conveying bin, with a conveying outlet at the bottom of one end of the conveying bin.

[0009] The transverse conveying device uses a screw conveyor mechanism to transport all the products in the conveying bin to the conveying outlet at one end, so that the products can smoothly enter the second crushing device. While conveying the materials, the transverse conveying device also plays a stirring role, making the product color more uniform and thus improving the product quality.

[0010] Preferably, the second crushing device includes a second crushing chamber fixed inside the hopper and a second crushing shaft arranged laterally in the center of the second crushing chamber. The inner wall of the second crushing chamber is provided with a plurality of second crushing rods along the axial direction. The second crushing rods are fixed to the second crushing shaft by rotating disks at both ends. The top of the second crushing chamber is provided with a second inlet that matches the conveying outlet, and the side is provided with a second outlet. A second screen is fixed on the second outlet.

[0011] The second crushing device is used for secondary crushing to obtain products with smaller particles. Because the first crushing chamber removes coarser and harder impurities, the second screen is less likely to break frequently, ensuring product quality (no impurities). The holes on the second screen are smaller than those on the first screen. The position of the second crushing rod in the radial direction of the second crushing shaft can be adjusted as needed. When the distance between the second crushing rod and the second crushing shaft is greater, that is, the gap between the second crushing rod and the inner wall of the second crushing chamber is smaller, the particles of the crushed product are relatively smaller. When the distance between the second crushing rod and the second crushing shaft is closer, that is, the gap between the second crushing rod and the inner wall of the second crushing chamber is larger, the particles of the crushed product are relatively larger.

[0012] Preferably, the motor is fixed to the top of the hopper, and a drive pulley is fixed to the output shaft of the motor. A first left pulley and a first right pulley are fixed to the two ends of the first crushing shaft outside the hopper, respectively. A transverse conveying pulley is fixed to the right end of the shaft of the screw conveyor outside the hopper, and a second left pulley is fixed to the left end of the second crushing shaft outside the hopper. The drive pulley is connected to the first left pulley, the drive pulley is connected to the second left pulley, and the first right pulley is connected to the transverse conveying pulley by belts.

[0013] The first crushing shaft, the screw conveyor mechanism, and the second crushing shaft are driven by a single motor, which reduces the use of motors, simplifies the overall structure, and lowers energy consumption.

[0014] Preferably, both the first and second crushing rods are made of angle iron, and both ends of the first and second crushing rods are welded with fixing seats, which are fixed to the rotating disk by bolts.

[0015] The two ends of the first and second crushing rods are fixed to the rotating disk by a fixed base, which facilitates the replacement and maintenance of the crushing rods.

[0016] This invention integrates a first crushing device, a transverse conveying device, and a second crushing device within the same hopper. After initial crushing by the first crushing device, the material yields a product with larger particles. After secondary crushing by the second crushing device, the material yields a product with smaller particles. The transverse conveying device then feeds the product from the first crushing device into the second crushing device. This structural design not only simplifies the overall structure of the crushing device but also directly yields the desired product after crushing, saving labor, reducing the labor intensity of workers, and greatly improving crushing efficiency.

[0017] This invention uses a single motor to drive the first crushing device, the transverse conveying device, and the second crushing device simultaneously, reducing the use of motors and effectively lowering energy consumption.

[0018] In this invention, the material is stirred in the first crushing device, the transverse conveying device, and the second crushing device. The three stirring processes greatly improve the consistency of the product color.

[0019] Compared with the prior art, this utility model solves the problems of product impurities, frequent sieve breakage, and inconsistent product color, while also reducing labor intensity and lowering equipment energy consumption. Attached Figure Description

[0030] like Figure 1-3 As shown, a three-shaft crusher includes a hopper 1, and a first crushing device 2, a transverse conveying device 3, and a second crushing device 4 arranged sequentially from top to bottom within the hopper 1. The first crushing device 2 performs initial crushing of the material, and the resulting larger particles are then conveyed to the second crushing device 4 via the transverse conveying device 3. The second crushing device 4 performs secondary crushing of the material, resulting in smaller particles. The first crushing device 2, the transverse conveying device 3, and the second crushing device 4 are all driven by a motor 5. The bottom of the hopper 1 is a hopper outlet 6, and the product obtained by the second crushing device 4 is discharged from the hopper outlet 6.

[0031] The first crushing device 2 includes a first crushing chamber 21 fixed inside the hopper 1 and a first crushing shaft 22 horizontally arranged at the center of the first crushing chamber 21. Multiple first crushing rods 23 are axially arranged on the inner side of the inner wall of the first crushing chamber 21. The first crushing rods 23 are fixed to the first crushing shaft 22 via rotating disks 7 at both ends. The top of the first crushing chamber 21 has a first feed inlet 24, and the side has a first discharge outlet. A first screen 25 is fixed to the first discharge outlet. The first crushing shaft 22 drives the first crushing rods 23 to perform initial crushing of the material in the first crushing chamber 21 via the rotating disks 7. Simultaneously, the material in the first crushing chamber 21 reaches the inner side of the first screen 25 under the drive of the first crushing rods 23. Material that meets the requirements passes through the first screen 25 and leaves the first crushing chamber 21, while material that does not meet the requirements returns to the first crushing chamber 21 for further crushing.

[0032] The transverse conveying device 3 includes a conveying chamber 31 with an open top and a spiral conveying mechanism 32 arranged transversely in the center of the conveying chamber 31. Since the spiral conveying mechanism 32 is a conventional material conveying mechanism, the alignment structure of this utility model will not be described in detail, and its specific structure is not shown in the attached drawings. A conveying outlet 33 is provided at the bottom of one end of the conveying chamber 31. Since the top of the conveying chamber 31 is completely open, the material that leaves the first screen 25 after being crushed by the first crushing device 2 falls directly into the conveying chamber 31. Under the action of the spiral conveying mechanism 32, all the material in the conveying chamber 31 is conveyed to one end of the conveying chamber 31 and leaves the conveying chamber 31 from the conveying outlet 33.

[0033] The second crushing device 4 includes a second crushing chamber 41 fixed inside the hopper 1, and a second crushing shaft 42 horizontally arranged at the center of the second crushing chamber 41. Multiple second crushing rods 43 are axially arranged on the inner wall of the second crushing chamber 41. The second crushing rods 43 are fixed to the second crushing shaft 42 via rotating disks 7 at both ends. The top of the second crushing chamber 41 has a second inlet 44 matching the conveying outlet 33, and the side has a second outlet. A second screen 45 is fixed to the second outlet. The second crushing shaft 42 drives the second crushing rods 43 to perform secondary crushing of the material in the second crushing chamber 41 via the rotating disks 7. Simultaneously, the material in the second crushing chamber 41 reaches the inner side of the second screen 45 under the drive of the second crushing rods 43. Material that meets the requirements passes through the second screen 45 and leaves the second crushing chamber 41, exiting directly from the hopper outlet 6. Material that does not meet the requirements returns to the second crushing chamber 41 for further crushing.

[0034] The motor 5 is fixed to the top of the hopper 1. A drive pulley 51 is fixed to the output shaft of the motor 5. A first left pulley 221 and a first right pulley 222 are fixed to the two ends of the first crushing shaft 22 outside the hopper 1, respectively. A transverse conveying pulley 321 is fixed to the right end of the shaft of the screw conveying mechanism 32 outside the hopper 1. A second left pulley 421 is fixed to the left end of the second crushing shaft 42 outside the hopper 1. The drive pulley 51 is connected to the first left pulley 221, the drive pulley 51 is connected to the second left pulley 421, and the first right pulley 222 is connected to the transverse conveying pulley 321 by belts. The motor 5 drives the first crushing shaft 22, the screw conveying mechanism 32 and the second crushing shaft 42 simultaneously by belts. The structure is simple and the energy consumption is low.

[0035] The first crushing rod 23 and the second crushing rod 43 are both made of angle iron. Both ends of the first crushing rod 23 and the second crushing rod 43 are welded with fixing seats 8. The fixing seats 8 are fixed to the rotating disk 7 by bolts 9.

[0036] The working principle of this utility model is as follows:

[0037] 1. The material to be crushed is put into the first crushing chamber 21 through the first feed port 24 for initial crushing. After crushing, the material that meets the requirements of the first screen 25 leaves the first crushing chamber 21 through the first screen 25 and falls into the conveying chamber 31 below. The material that does not meet the requirements of the first screen 25 and impurities remain in the first crushing chamber 21 for further crushing. The wire diameter of the first screen 25 is relatively thick, so impurities are not likely to damage the first screen 25 when passing through the screen, thereby improving the service life of the first screen 25.

[0038] 2. The material in the conveying bin 31 is conveyed to one end of the conveying bin 31 by the screw conveyor mechanism 32 and leaves the conveying bin 31 from the conveying outlet 33. The screw conveyor mechanism 32 also stirs the material while conveying, so that the product color is more consistent.

[0039] 3. The material leaving from the conveyor outlet 33 enters the second crushing chamber 41 through the second feed inlet 44 for secondary crushing. The material that meets the requirements of the second screen 45 after crushing leaves the second crushing chamber 41 through the second screen 45 and is discharged directly from the hopper outlet 6. The material that does not meet the requirements of the second screen 45 remains in the second crushing chamber 41 for further crushing.

[0040] The material entering hopper 1 is directly crushed into the required material after primary and secondary crushing, which saves labor, reduces the labor intensity of workers, and greatly improves crushing efficiency.

[0041] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
