Description

Technical Field

[0001] This utility model relates to the field of screening equipment for cement production, and more specifically, to a high-efficiency screening equipment for cement production. Background Technology

[0002] Cement: A powdered hydraulic inorganic binder. When mixed with water, it forms a paste that hardens in air or water and can firmly bind materials such as sand and stone together. During cement production, the raw materials need to be screened to obtain a suitable particle size.

[0003] A search revealed that patent application CN202220936393.7 discloses a screening device for cement production, comprising a support plate, a mounting plate, a horizontal plate, a connecting plate, a connecting seat, a raw material box, a shaking component, a screen, a swaying component, and a collection box. The cement to be screened falls from the discharge port in the raw material box onto the screen mounted on the horizontal plate, where it is screened. Qualified cement falls into the collection box at the bottom. During the screening process, the shaking component continuously vibrates the screen, accelerating the screening speed and preventing clogging. The swaying component moves the connecting plate back and forth, further increasing the screening speed and improving the efficiency and practicality of the device. However, it still has the following drawbacks:

[0004] (1) In the process of screening cement raw materials, the screening device in the prior art is inconvenient to send out the large pieces of material screened out, and at the same time, it is necessary to manually remove the small particles of material in the collection box, resulting in low screening efficiency.

[0005] (2) The screening devices in the prior art are not convenient to screen out iron impurities in the raw materials of cement production, resulting in poor screening effect.

[0006] Therefore, we have made improvements to this and proposed a high-efficiency screening equipment for cement production. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a high-efficiency screening equipment for cement production, including a frame 1. Two sets of rotating seats 2 are symmetrically and fixedly connected to the upper part of the frame 1. A rotating shaft 3 is rotatably connected between each set of rotating seats 2. Drive wheels 4 are fixedly connected to both ends of the rotating shaft 3. Connecting sleeves 5 are rotatably connected between adjacent drive wheels 4. A screen cylinder 6 is fixedly connected between the connecting sleeves 5. A feed hopper 7 is provided at the top of the screen cylinder 6. The feed hopper 7 is fixedly connected to the frame 1 via a support rod 8. A first conveying frame 9 is provided on the lower side of the screen cylinder 6. Support rods 10 are rotatably connected to the front and rear side walls of the left end of the first conveying frame 9. The bottom ends of the support rods 10 are fixedly connected to the frame 1. First conveying rollers 11 are rotatably connected to both ends of the first conveying frame 9. A first conveyor belt 12 is drivenly connected to the first conveying rollers 11. A symmetrical and fixed... The fixed connection has two connecting seats 13, and each of the two connecting seats 13 is rotatably connected to a hydraulic cylinder 14. The drive end of the hydraulic cylinder 14 is rotatably connected to a connecting seat 15, which is fixedly connected to the first conveying frame 9. The left end of the frame 1 is provided with a screening mechanism 16. The material enters the screen cylinder 6 from the feed hopper 7. During the rotation of the screen cylinder 6, the material is initially screened due to centrifugal force and the screen hole structure of the screen cylinder 6. Larger particles remain in the screen cylinder 6, while smaller particles fall through the screen holes. The smaller particles after initial screening fall onto the first conveyor belt 12 and are transported by the first conveyor belt 12 to the subsequent processing stage without manual transfer. Large pieces of material fall and are transported. By extending and retracting the hydraulic cylinder 14, the tilt angle of the first conveying frame 9 can be adjusted, thereby changing the conveying slope of the first conveyor belt 12 to adapt to different conveying needs.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the iron screening mechanism 16 further includes a base frame 1601 fixed to the left end of the frame 1. A second conveying frame 1602 is fixedly connected to the upper end face of the base frame 1601. Second conveying rollers 1603 are rotatably connected to both ends of the second conveying frame 1602. A second conveyor belt 1604 is driven between the second conveying rollers 1603. Two mounting plates 1605 are symmetrically and fixedly connected to the upper end face of the second conveying frame 1602. A magnetic roller 1606 is rotatably connected between 605. A scraper frame 1607 is provided on the left side of the magnetic roller 1606. The scraper frame 1607 is fixedly connected to the second conveyor frame 1602. The second conveyor belt 1604 conveys the raw material after it has been screened by the screen cylinder 6. During the conveying process, the material passes under the magnetic roller 1606. The magnetic roller 1606 adsorbs the iron impurities in the material.

Wheel 1614 is connected to the third pulley 1613 via the second synchronous belt 1615. The second pulley 1611 is driven to rotate by the first motor 1610. The second pulley 1611 drives the first pulley 1608 to rotate via the first synchronous belt 1612, which in turn drives the second conveyor roller 1603 to rotate, thereby driving the second conveyor belt 1604 to run. At the same time, the second conveyor roller 1603 drives the third pulley 1613. The third pulley 1613 drives the fourth pulley 1614 to rotate via the second synchronous belt 1615, so that the magnetic roller 1606 and the second conveyor roller 1603 rotate synchronously, ensuring that iron impurities can be adsorbed and separated in a timely manner.

[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a guide plate 17 is provided at the bottom of the screen cylinder 6. The guide plate 17 is fixedly connected to the frame 1 by two fixing rods 18. The guide plate 17 facilitates the guidance and transportation of large pieces of raw material screened by the screen cylinder 6 to the second conveyor belt 1604.

[0035] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, a fifth pulley 24 is fixedly connected to the front end of the upper first conveying roller 11, and an assembly frame 25 is fixedly connected to the lower end face of the first conveying frame 9. A third motor 26 is fixedly connected inside the assembly frame 25, and a sixth pulley 27 is fixedly connected to the drive end of the third motor 26. The sixth pulley 27 is connected to the fifth pulley 24 via a fourth synchronous belt 28. The sixth pulley 27 is driven to rotate by the third motor 26, and the sixth pulley 27 drives the fifth pulley 24 to rotate via the fourth synchronous belt 28, thereby causing the first conveying roller 11 connected to it to rotate, thereby driving the first conveyor belt 12 to run and realize the conveying of materials.

[0036] Specifically, in operation, this high-efficiency screening equipment for cement production works as follows: The extension and retraction of the hydraulic cylinder 14 drives the first conveyor frame 9 to rotate, thereby adjusting the conveying height of the first conveyor belt 12. The second motor 21 is started, driving the second double-groove pulley 22 to rotate. The second double-groove pulley 22, via the third synchronous belt 23, drives the first double-groove pulley 19 to rotate, which in turn causes the connected shaft 3 to rotate. The rotation of the shaft 3 drives the drive wheel 4 to rotate, which in turn drives the connecting sleeve 5 and the screen cylinder 6 to rotate. The third motor 26 is started, driving the sixth pulley 27 to rotate. The sixth pulley 27, via the fourth synchronous belt 28, drives the fifth pulley 24 to rotate, which in turn causes the connected first conveyor roller 11 to rotate, thereby driving the first conveyor belt 12 to run, guiding the cement raw materials into the feed hopper 7. The cement raw materials enter the screen cylinder 6, and small particles fall into the first... Large pieces of material are conveyed on conveyor belt 12. They fall through guide plate 17 and enter the second conveyor belt 1604. The first motor 1610 is started to drive the second pulley 1611 to rotate. The second pulley 1611 drives the first pulley 1608 to rotate through the first synchronous belt 1612, which in turn drives the second conveyor roller 1603 to rotate, thereby driving the second conveyor belt 1604 to run. At the same time, the second conveyor roller 1603 drives the third pulley 1613. The third pulley 1613 drives the fourth pulley 1614 to rotate through the second synchronous belt 1615, so that the magnetic roller 1606 rotates synchronously with the second conveyor roller 1603. Large pieces of raw material pass under the magnetic roller 1606. The magnetic roller 1606 adsorbs iron impurities mixed in the material. As the magnetic roller 1606 rotates, the iron impurities are carried to the scraper frame 1607 and scraped off by the scraper frame 1607, thus realizing the screening of iron impurities.
