Description

Technical Field

[0002] Cement grinding is the final process in cement manufacturing.

After the powder selection blade crushes the cement particles into cement powder, starting a second motor, and the second motor drives the powder selection barrel to rotate through a flip column, and pours the cement powder onto a powder separation net, and the cement powder that meets the standard falls into a diversion bucket, and a cement packaging bag is put on the bottom of the diversion bucket for bagging, and the cement that does not meet the standard rolls out of the fragment hole along the powder separation net.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention is provided with a crushing mechanism, two integrated storage and screening mechanisms and a rotary exchange mechanism. When the integrated storage and screening mechanism is filled with cement raw materials, the crushing mechanism works, and the cement raw materials in the integrated storage and screening mechanism flow toward the crushing mechanism. The crushing mechanism crushes the cement raw materials in the upper integrated storage and screening mechanism, and the cement raw materials fall into the integrated storage and screening mechanism located at the lower end of the crushing mechanism after being crushed. The cement raw materials that are crushed and qualified flow out of the integrated storage and screening mechanism, while the cement raw materials that are crushed and unqualified remain in the integrated storage and screening mechanism. When the cement raw materials in the integrated storage and screening mechanism located at the upper end of the crushing mechanism are crushed and unqualified, the cement raw materials are crushed and unqualified. After all the raw materials have passed through the crushing mechanism, the integrated material screening mechanism at the upper end of the crushing mechanism is in an empty state, and the rotary switching mechanism works to swap the positions of the two integrated material screening mechanisms at the upper and lower ends of the crushing mechanism.

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figures 1 to 13As shown: a raw material crushing equipment for cement processing, including a rectangular frame 1, a feeding mechanism 2, a crushing mechanism 3, an integrated storage material screening mechanism 4 and a rotary exchange mechanism 5; a rectangular frame 1; the feeding mechanism 2 is arranged at the upper end inside the rectangular frame 1, the feeding mechanism 2 includes a feeding box 21 and a first lifting structure 22, the feeding box 21 is connected to an external conveying device, the first lifting structure 22 is arranged on the rectangular frame 1, and the first lifting structure 22 is used to change the height of the feeding box 21; the crushing mechanism 3 is arranged in the middle of the rectangular frame 1, and the crushing mechanism 3 is used to crush cement into qualified products; there are two integrated storage material screening mechanisms 4, and the two integrated storage material screening mechanisms 4 are respectively arranged on both sides of the crushing mechanism 3, the integrated storage material screening mechanism 4 located above the crushing mechanism 3 is used to store the raw materials put in by the feeding mechanism 2, and the integrated storage material screening mechanism 4 located below the crushing mechanism 3 is used to screen out unqualified products; the rotary exchange mechanism 5 is arranged at both ends of the crushing mechanism 3, and the rotary exchange mechanism 5 is used to exchange the positions of the two integrated storage material screening mechanisms 4.

[0035] The feeding mechanism 2 is connected to an external conveying device, and can automatically convey the cement raw materials to the integrated material screening mechanism 4 located at the upper end of the crushing mechanism 3. The two integrated material screening mechanisms 4 are respectively located at the upper and lower ends of the crushing mechanism 3. The upper integrated material screening mechanism 4 is used to store the cement raw materials to be crushed, and the lower integrated material screening mechanism 4 is used to collect and screen the crushed cement particles to distinguish qualified and unqualified products. When the integrated material screening mechanism 4 is full of cement raw materials, the crushing mechanism 3 works, and the cement raw materials in the integrated material screening mechanism 4 flow toward the crushing mechanism 3. The crushing mechanism 3 crushes the cement raw materials in the upper integrated material screening mechanism 4, and the cement raw materials fall into the integrated material screening mechanism 4 located at the lower end of the crushing mechanism 3 after being crushed, and the crushed qualified cement raw materials flow out of the integrated material screening mechanism 4. The material screening integrated mechanism 4 is operated, while the unqualified cement raw materials are retained in the stock screening integrated mechanism 4. When all the cement raw materials in the stock screening integrated mechanism 4 located at the upper end of the crushing mechanism 3 have passed through the crushing mechanism 3, the stock screening integrated mechanism 4 located at the upper end of the crushing mechanism 3 is in an empty state, and the rotary switching mechanism 5 works to swap the positions of the two stock screening integrated mechanisms 4 at the upper and lower ends of the crushing mechanism 3. The stock screening integrated mechanism 4 with unqualified cement raw materials is at the upper end of the crushing mechanism 3, and the feeding mechanism 2 injects the cement raw materials into the stock screening integrated mechanism 4, and then the crushing mechanism 3 works, and the above process is repeated, so that the unqualified cement raw materials can enter the crushing mechanism 3 in time for crushing again, thereby realizing continuous secondary processing of unqualified products and improving the production utilization rate of cement raw materials.

[0036] Reference Figure 3 , Figure 4 and Figure 5As shown: the material storage and screening integrated mechanism 4 includes a material storage hopper 41 and a screening structure 42; the material storage hopper 41 is funnel-shaped, the small end of the material storage hopper 41 is connected to the crushing mechanism 3, and the large end of the material storage hopper 41 is open; there are two screening structures 42, and the two screening structures 42 are covered on the large end of the material storage hopper 41, and the screening structure 42 includes a mounting frame 421, a reinforcing connecting plate 422 and a screening intercepting net 423, the mounting frame 421 is slidably connected to the material storage hopper 41, the two ends of the reinforcing connecting plate 422 are connected to the mounting frame 421, and the screening intercepting net 423 is arranged on the mounting frame 421.

[0037] When feeding is required, the two screening structures 42 at the upper end are away from each other, leaving enough space for the feeding mechanism 2 to inject the cement raw materials into the storage hopper 41. After the feeding is completed, the screening structures 42 abut against each other to close the upper end of the storage hopper 41, effectively preventing the splashing of the cement raw materials during the crushing process, improving production safety and environmental cleanliness. At the same time, air is allowed to pass through the screening interception net 423, which means that during the falling process of the cement raw materials, the air pressure in the storage hopper 41 can remain relatively stable, reducing the resistance of the cement raw materials when moving toward the crushing mechanism 3, ensuring the smooth flow and efficient processing of the raw materials. The screening interception net 423 located at the lower end of the crushing mechanism 3 screens and intercepts the cement. Qualified cement particles can smoothly pass through the screening interception net 423 and fall to the outside of the storage hopper 41 for subsequent processing or collection, while unqualified large-particle cement is intercepted in the storage hopper 41, thereby realizing automatic screening of cement raw materials.

[0038] Reference Figure 4 and Figure 6As shown: the integrated storage and screening mechanism 4 also includes an opening and closing structure 43 and a guide structure 44; the opening and closing structure 43 has two, and the two opening and closing structures 43 are respectively arranged on both sides of the storage hopper 41, and the opening and closing structure 43 is used to drive the two screening structures 42 to move closer to or away from each other, and the opening and closing structure 43 includes a first moving block 431, a first linear driving structure 432 and two first driving plates 433, the first moving block 431 is arranged in parallel on one side of the storage hopper 41, the first linear driving structure 432 is installed on the storage hopper 41, the first linear driving structure 432 is used to drive the first moving block 431 to move in the vertical direction, and the two first driving plates 433 are respectively arranged At both ends of the first moving block 431, both ends of the first driving plate 433 are respectively axially connected to the first moving block 431 and one end of the reinforcing connecting plate 422; there are two guide structures 44, and the two guide structures 44 are respectively arranged on both sides of the screening structure 42, and the guide structure 44 includes a second rectangular frame 441, a guide rod 442 and two second moving blocks 443, the second rectangular frame 441 is installed on the storage hopper 41, and the two ends of the guide rod 442 are respectively connected to the two ends of the second rectangular frame 441, and the two second moving blocks 443 are arranged on the guide rod 442, and the two sides of the second moving block 443 are respectively connected to the first driving plate 433 and the reinforcing connecting plate 422.

[0039] The two screening structures 42 located at the lower end of the crushing mechanism 3 are close to each other, closing the large end of the storage hopper 41. If the two screening structures 42 deviate after being close to each other, unqualified cement may flow out from between the two screening structures 42. By setting two opening and closing structures 43 and two guide structures 44, the two opening and closing structures 43 work simultaneously, and the first linear drive 533 drives the first moving block 431 to move from the large end of the storage hopper 41 toward the small end of the storage hopper 41. The first moving block 431 drives the two first driving plates 433 to move. The two first driving plates 433 respectively drive the two second moving blocks 443 to approach each other. The two second moving blocks 443 drive the two screening structures 42 to move. The two screening structures 42 are guided by the guide rod 442 to approach each other, so that the two corresponding end faces of the two screening structures 42 are pressed against each other to avoid a gap between the two screening structures 42, thereby preventing unqualified cement from merging into qualified cement.

[0040] Reference Figure 4 and Figure 7As shown: the integrated material screening mechanism 4 also includes a vibration structure 45, which has two vibration structures 45. The two vibration structures 45 are respectively arranged on one side of the two sub-screening structures 42, and the vibration structure 45 includes a transmission column 451, a vibration swing arm 452, a third rotating shaft 453 and a reciprocating swinging structure 454; one end of the transmission column 451 is connected to the sub-screening intercepting net 423, a slot is provided in the mounting frame 421, and the sub-screening intercepting net 423 is slidably arranged in the mounting frame 421; one end of the vibration swing arm 452 is provided with an inclined groove 4521, and the other end of the transmission column 451 is inserted into the inclined groove 4521; the third rotating shaft 453 is arranged at the other end of the vibration swing arm 452, and the middle part of the third rotating shaft 453 is axially connected to the reinforcing connecting plate 422; the reciprocating swinging structure 454 is arranged on the reinforcing connecting plate 422, and the reciprocating swinging structure 454 is used to drive the third rotating shaft 453 to swing.

[0041] During the screening process, unqualified cement particles will gradually accumulate on the screening intercepting net 423, reducing the effective screening area, thereby affecting the screening efficiency and accuracy. By setting two vibration structures 45, the two vibration structures 45 work simultaneously, and the reciprocating swinging structure 454 drives the third rotating shaft 453 to swing within a certain angle range. The third rotation drives the vibration swing arm 452 to swing, and the inclined groove 4521 on the vibration swing arm 452 drives the transmission column 451 to move. The transmission column 451 drives the screening filter to swing back and forth in the installation frame 421. Relative sliding occurs between the intercepted unqualified cement particles and the screening filter, ensuring that the screening intercepting net 423 always maintains a large effective screening area, thereby effectively removing the cement particles accumulated on the screening filter.

[0042] Reference Figure 3 , Figure 4 and Figure 8 As shown: the integrated material screening mechanism 4 also includes a toggle structure 46, and the toggle structure 46 includes a toggle component 461; there are two toggle components 461, and the two toggle components 461 are arranged in parallel inside the material storage hopper 41. The toggle component 461 includes a fourth rotating shaft 4611 and a toggle tool 4612. The two ends of the fourth rotating shaft 4611 are respectively connected to the two opposite sides of the material storage hopper 41, and the toggle tool 4612 is sleeved on the fourth rotating shaft 4611.

[0043] After the crushing mechanism 3 crushes the cement raw material, the cement particles fall onto the screening interception net 423. Due to the limited falling area, the utilization area of ​​the screening interception net 423 is small, resulting in limited processing speed. By setting the toggle assembly 461, the two toggle assemblies 461 work at the same time, and the two fourth rotating shafts 4611 rotate in opposite directions. The two toggle cutters 4612 therefore rotate in opposite directions. The cement particles falling on the toggle assembly 461 come into contact with the rotating toggle cutters 4612, and the toggle cutters 4612 exert a force on the cement particles toward the inner wall of the storage hopper 41. This force causes the cement particles to collide with the inner wall of the storage hopper 41 and then splash, thereby increasing the dispersion of the cement particles in the storage hopper 41, allowing more cement particles to have the opportunity to come into contact with the screening interception net 423, thereby increasing the utilization area of ​​the screening interception net 423.

[0044] Reference Figure 3 and Fig. 9 As shown: the crushing mechanism 3 includes a first rectangular frame 31, a crushing assembly 32 and a driving structure 33; the first rectangular frame 31 is horizontally arranged, and the small ends of the two storage hoppers 41 are respectively connected to the upper and lower sides of the first rectangular frame 31; the crushing assembly 32 includes a second rotating shaft 321 and a crushing roller 322, the second rotating shaft 321 has an even number, and the even number of second rotating shafts 321 are arranged parallel to each other, and the two ends of the second rotating shaft 321 are respectively connected to the two ends of the first rectangular frame 31, the crushing roller 322 has an even number, and the even number of crushing rollers 322 are respectively arranged on the even number of second rotating shafts 321; the driving structure 33 is arranged At both ends of the crushing assembly 32, the driving structure 33 is used to drive the even number of second rotating shafts 321 to rotate simultaneously. The driving structure 33 includes an even number of linkage gears 331, a first rotation driver 332 and a transmission connection sleeve 333. The linkage gear 331 is arranged at one end of the second rotating shaft 321. The even number of linkage gears 331 are respectively matched with the even number of second rotating shafts 321, and two adjacent linkage gears 331 are meshed. The first rotation driver 332 is arranged at the other end of the second rotating shaft 321, and the two ends of the transmission connection sleeve 333 are respectively connected to the second rotating shaft 321 and the first rotation driver 332.

[0045] When the pulverizing mechanism 3 pulverizes the cement raw material, it is necessary to ensure both the quality of the product and the efficiency of production. By setting the first rectangular frame 31, the pulverizing assembly 32 and the driving structure 33, an even number of pulverizing rollers 322 are closely arranged in the first rectangular frame 31, which can effectively prevent the un-pulverized cement raw material from leaking out from the gap between the pulverizing rollers 322 and the first rectangular frame 31, ensuring that all the raw materials can be fully pulverized. The first rotary driver 332 drives the transmission connection sleeve 333 to rotate, and the transmission connection sleeve 333 drives a second rotating shaft 321 to rotate. The second rotating shaft 321 is connected to the transmission connection sleeve 333 by an even number of linkage gears. 331 drives the remaining second rotating shafts 321 to rotate, and the rotation directions of two adjacent second rotating shafts 321 are opposite. The two adjacent second rotating shafts 321 drive the two adjacent crushing rollers 322 to rotate in opposite directions. The cement raw material passes between the two adjacent crushing rollers 322, and the two crushing rollers 322 crush the cement raw material. Through the mutual cooperation of an even number of crushing rollers 322 and the opposite rotation directions of adjacent crushing rollers 322, the cement raw material is subjected to shear force and extrusion force from two directions when passing between the adjacent crushing rollers 322, thereby achieving efficient crushing of the cement raw material.

[0046] Reference Figure 8 and Fig.10 As shown: the toggle structure 46 also includes a linkage component 462, which has two linkage components 462, and the two linkage components 462 correspond to the two toggle components 461 respectively. The linkage component 462 includes a first transmission wheel 4621, a second transmission wheel 4622 and a transmission belt 4623. The two first transmission wheels 4621 are respectively connected to two second rotating shafts 321 with opposite rotation directions, the second transmission wheel 4622 is connected to the fourth rotating shaft 4611, and the diameter of the second transmission wheel 4622 is smaller than the diameter of the first transmission wheel 4621, and the two ends of the transmission belt 4623 are respectively mounted on the first transmission wheel 4621 and the second transmission wheel 4622.

[0047] Since the diameter of the second transmission wheel 4622 is smaller than that of the first transmission wheel 4621, according to the principle of transmission ratio, when the first transmission wheel 4621 rotates one circle, the second transmission wheel 4622 will rotate multiple circles, so that the power transmitted from the second rotating shaft 321 to the fourth rotating shaft 4611 is significantly amplified in rotation speed. When the crushing mechanism 3 is working, the second rotating shaft 321 drives the first transmission wheel 4621 to rotate, the first transmission wheel 4621 drives the second transmission wheel 4622 to rotate through the transmission belt 4623, the second transmission wheel 4622 drives the fourth rotating shaft 4611 to rotate, and the fourth rotating shaft 4611 drives the shifting tool 4612 to rotate. As the rotation speed of the shifting tool 4612 increases, the force it generates on the cement particles also increases, thereby realizing the synchronous operation of the crushing component 32 and the crushing component.

[0048] Reference Figure 1 and Fig.11 As shown: the rotation exchange mechanism 5 also includes a second lifting structure 51 and a rotating structure 52; the second lifting structure 51 has two, and the two second lifting structures 51 are respectively arranged on both sides of the inside of the rectangular frame 1, and the second lifting structure 51 includes a third moving block 511 and a second linear driving structure 512, and the second linear driving structure 512 is used to drive the third moving block 511 to move in the vertical direction; the rotating structure 52 is arranged at both ends of the rectangular frame 1, and the rotating structure 52 includes a first connecting shaft 521, a second connecting shaft 522 and a second rotating driver 523, the first connecting shaft 521 and the second connecting shaft 522 are respectively arranged at both ends of the crushing mechanism 3, the first connecting shaft 521 and the second connecting shaft 522 are coaxially arranged, and the first connecting shaft 521 and the second connecting shaft 522 are respectively arranged on the two third moving blocks 511, and the second rotating driver 523 is used to drive the first connecting shaft 521 to rotate.

[0049] The distance between the integrated material screening mechanism 4 located at the lower end of the crushing mechanism 3 and the external conveying device for transferring qualified cement is relatively close, which can prevent the cement from escaping into the air. When the rotating exchange mechanism 5 exchanges the two integrated material screening mechanisms 4, the integrated material screening mechanism 4 located at the lower end of the crushing mechanism 3 will come into contact with the conveying device. By setting two second lifting structures 51 and a rotating structure 52, the two second lifting structures 51 work simultaneously, and the second linear driving structure 51233 drives the third moving block 511 to move upward. The two third moving blocks 511 respectively drive the first connecting shaft 521 and the second connecting shaft 522 to move upward. The first connecting shaft 521 and the second connecting shaft 522 drive the crushing mechanism 3 and the two integrated material screening mechanisms 4 to move upward as a whole, so that there is a sufficient distance between the integrated material screening mechanism 4 located at the lower end of the crushing mechanism 3 and the conveying device, thereby avoiding potential collision and interference.

[0050] Reference Fig.11 and Fig.12 As shown: the rotation exchange mechanism 5 also includes a fixed structure 53, which is arranged at one end of the second connecting shaft 522, and a vertical groove 5221 is opened at the end of the second connecting shaft 522. The fixed structure 53 includes a frame plate 531, an insert block 532 and a linear driver 533. The frame plate 531 is installed on one side of the third moving block 511, and the insert block 532 cooperates with the vertical groove 5221. The linear driver 533 is arranged on one side of the frame plate 531, and the output end of the linear driver 533 is connected to the insert block 532.

[0051] The vibration generated by the equipment during operation, especially when the integrated material storage and screening mechanism 4 located at the upper end of the crushing mechanism 3 is filled with cement raw materials, the center of gravity of the equipment will be biased upward, making the equipment more sensitive to vibration and prone to large swings. By setting the fixed structure 53, after the two integrated material storage and screening mechanisms 4 are swapped, the linear drive 533 drives the plug 532 to be inserted into the vertical groove 5221 at the end of the second connecting shaft 522, and the two ends of the plug 532 are respectively connected to the two ends of the frame plate 531, so that the second connecting shaft 522, the plug 532 and the frame plate 531 are fixedly connected, ensuring that the second connecting shaft 522 remains in a fixed state when rotation is not required, preventing accidental rotation, thereby achieving a stable fixation of the equipment in operation.

[0052] Reference Figure 3 and Fig.13 As shown: the material mechanism includes a loading box 21, a first lifting structure 22 and a crushing structure 23; a feeding port is opened at the upper end of the loading box 21; the first lifting structure 22 is arranged at the upper end of the rectangular frame 1, and the first lifting structure 22 is used to change the height of the loading box 21; the crushing structure 23 is arranged inside the loading box 21, and the crushing structure 23 includes a first rotating shaft 231, a crushing tool 232 and a rotating drive assembly 233, the two ends of the first rotating shaft 231 are respectively connected to the two ends of the loading box 21, the crushing tool 232 is sleeved on the first rotating shaft 231, and the rotating drive assembly 233 is arranged outside the loading box 21, and the rotating drive assembly 233 is used to drive the first rotating shaft 231 to rotate.

[0053] When the integrated material screening mechanism 4 rotates to the upper end of the crushing mechanism 3 and adjusts its position, the loading box 21 can be automatically extended into the material storage hopper 41 through the drive of the first lifting structure 22. During this process, the crushing structure 23 is started at the same time, and the rotating drive component 233 drives the first rotating shaft 231 to rotate, thereby driving the crushing tool 232 to rotate. The crushing tool 232 crushes the agglomerated part of the cement raw material entering and passing through the loading box 21. The crushing treatment of the cement raw material by the crushing structure 23 effectively solves the agglomeration problem that may occur in the cement raw material, improves the fluidity of the cement raw material, and makes the particle size of the cement raw material more uniform, which is beneficial to the subsequent screening, mixing or processing steps, thereby improving the overall production efficiency and product quality.

It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
