Description

Technical Field

[0001] This utility model relates to the field of cement feeding technology, and in particular to a cement feeding crusher. Background Technology

[0002] In the cement production and transportation process, cement feeding and subsequent conveying are key steps to ensure production efficiency and product quality. Cement is discharged into the feeding chute through a feeding hopper. However, during storage, due to factors such as moisture and pressure, cement is prone to forming lumps of varying sizes. Moreover, traditional feeding devices often lack effective flow control mechanisms, and cement material can easily surge into the feeding chute in large quantities suddenly. When the pneumatic valve is opened to discharge cement, a large amount of material enters the chute in a short period of time. The conveying capacity of the chute may not be able to match this in time, leading to material accumulation and blockage. Cement can easily surge into the feeding chute suddenly, causing blockages and dust emission. At the same time, if there are lumps of material, it is very easy to get stuck.

[0003] Based on the above situation, we propose a cement feeding crusher to solve the above problems. Utility Model Content

[0004] This utility model provides a cement feeding crusher to solve the problems in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A cement feeding crusher includes a multi-stage crushing unit and an intermittent feeding unit installed at the output end of the feeding hopper. The multi-stage crushing unit includes at least a coarse crushing component and a fine crushing component, with the fine crushing component located below the coarse crushing component. It is used to classify and crush cement agglomerated materials. The intermittent feeding component is located at the lower end of the multi-stage crushing unit and is used to control the pulverized cement material to intermittently enter the downstream feeding chute, thereby preventing the cement material from suddenly rushing into the feeding chute and causing blockage.

[0007] Preferably, the coarse crushing component includes a first rotating shaft and coarse dynamic crushing teeth equidistantly installed along the axial direction of the first rotating shaft. The inside of the hopper is provided with a plurality of coarse static crushing teeth that are misaligned with the coarse dynamic crushing teeth. The fine crushing component includes a second rotating shaft and fine dynamic crushing teeth equidistantly installed along the axial direction of the second rotating shaft. The inside of the hopper is provided with a plurality of fine static crushing teeth that are misaligned with the fine dynamic crushing teeth, and the distance between two adjacent coarse dynamic crushing teeth is greater than the distance between two adjacent fine dynamic crushing teeth.

[0008] Preferably, one end of the second rotating shaft is connected to a drive motor, and both the first and second rotating shafts are provided with gears, and the two gears mesh with each other.

[0009] Preferably, the intermittent feeding assembly includes a rotating rod rotatably connected to the feeding hopper, and a plurality of material distribution plates are equidistantly connected on the rotating rod, with a material storage space formed between two adjacent material distribution plates.

[0010] Preferably, the rotating rod and the second rotating shaft are connected by a synchronous transmission mechanism.

[0012] Preferably, the coarse dynamic crushing teeth and the fine dynamic crushing teeth are spirally distributed on the first rotating shaft and the second rotating shaft, respectively, which enables the cement blocks to move axially during the crushing process.

[0013] The beneficial effects of this utility model are as follows: Through the multi-stage crushing mechanism combining coarse and fine stages, the coarse crushing component can first crush large-sized agglomerated materials into smaller pieces, which are then further refined by the fine crushing component. This can better adapt to various materials, ensure crushing effect, prevent agglomerated materials from clogging subsequent equipment, and under the action of the intermittent feeding component, the crushed material intermittently enters the feeding chute, avoiding the phenomenon of sudden large-scale cement influx causing dust emission.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Reference Figures 1-3As shown, a cement feeding crusher includes a multi-stage crushing unit installed at the output end of the feeding hopper 1. The multi-stage crushing unit includes at least a coarse crushing component 2 and a fine crushing component 3, with the fine crushing component 3 located below the coarse crushing component 2. A medium crushing component may also be provided as needed for classifying and crushing cement agglomerated materials. Specifically, the coarse crushing component 2 includes a first rotating shaft 21 and coarse dynamic crushing teeth 22 equidistantly installed along the axial direction of the first rotating shaft 21. The inside of the feeding hopper 1 is provided with a plurality of coarse static crushing teeth 23 that are offset from the coarse dynamic crushing teeth 22. The fine crushing component 3 includes a second rotating shaft 31 and fine dynamic crushing teeth 32 equidistantly installed along the axial direction of the second rotating shaft 31. The inside of the hopper 1 is provided with multiple fine static crushing teeth 33 that are offset from the fine dynamic crushing teeth 32, and the distance between two adjacent coarse dynamic crushing teeth 22 is greater than the distance between two adjacent fine dynamic crushing teeth 32. When the first rotating shaft 21 or the second rotating shaft 31 drives the coarse dynamic crushing teeth 22 or the fine dynamic crushing teeth 32 to rotate, shearing forces are generated with the coarse static crushing teeth 23 and the fine static crushing teeth 33 respectively, thereby impacting the contents of the hopper 1. The falling clumps of material are crushed by compression, while the powdery material falls through the gaps between the crushing teeth. The coarse dynamic crushing teeth 22 and the fine dynamic crushing teeth 32 are spirally distributed on the first rotating shaft 21 and the second rotating shaft 31, respectively, enabling axial movement of the cement clumps during the crushing process. On the upper first rotating shaft 21, the coarse dynamic crushing teeth 22 are spirally distributed. When cement clumps enter, the axial movement allows the clumps to be fully dispersed within a large space. The coarse crushing teeth at different positions act on the clumps sequentially, performing primary crushing of large pieces of material from multiple angles and at multiple frequencies. This effectively transforms large clumps into smaller fragments, providing more suitable material for the fine crushing of the second rotating shaft 31 below. The material after coarse crushing above falls into the fine crushing area of ​​the second rotating shaft 31 below. The fine dynamic crushing teeth 32 are also spirally distributed. During the falling process, the material moves axially to make full contact with the fine crushing teeth and is further finely ground. This coordinated falling and axial movement ensures that each part of the material can be fully crushed, improving the crushing quality and preventing clumped material from entering the downstream feed chute 5 and causing blockages.

[0021] Reference Figure 2As shown, furthermore, to prevent cement from suddenly rushing into the feeding chute 5 and causing blockages and dust emissions when the multiple feeding hoppers 1 on the feeding chute 5 are opened to discharge material, an intermittent feeding component 4 is provided at the lower end of the multi-stage crushing unit. This component controls the intermittent entry of the crushed cement material into the downstream feeding chute 5. The intermittent feeding component 4 includes a rotating rod 7 that is rotatably connected to the feeding hopper 1. Multiple distribution plates 71 are equidistantly connected on the circumference of the rotating rod 7, and a storage space 72 is formed between two adjacent distribution plates 71. When the material falling from the multi-stage crushing unit enters the storage space 72, and when the storage space 72 containing the material moves with the rotation of the rotating rod 7 to the position where the lower opening faces downward, the material will fall into the feeding chute 5 below. This process is repeated to achieve intermittent material falling, thus preventing the material from suddenly rushing into the feeding chute 5 and causing blockages.

[0022] Furthermore, a guide 9 is provided on the inner wall of the hopper 1. The guide 9 is located at the upper end of the multi-stage crushing unit. An installation cover 11 is provided on the inner wall of the hopper 1. The multi-stage crushing unit is located inside the installation cover 11. The output port of the guide 9 faces the center of the installation cover 11, that is, the middle part of the coarse dynamic crushing tooth 22, so that the material falls directly between the coarse dynamic crushing tooth 22 and the coarse static crushing tooth 23 as much as possible for crushing, and avoids some lumpy material falling to the edge of the installation cover 11.

[0023] One end of the second rotating shaft 31 is connected to a drive motor 6, which is installed on the outer wall of the hopper 1. Both the first rotating shaft 21 and the second rotating shaft 31 are equipped with gears 61, and the two gears 61 mesh with each other, which can make the first rotating shaft 21 and the second rotating shaft 31 rotate in opposite directions. This allows the coarse dynamic crushing teeth 22 and the fine dynamic crushing teeth 32 to crush the material from different angles, which can more comprehensively act on all parts of the cement block, reduce the insufficient crushing caused by uneven force on the material, and further improve the crushing effect.

[0024] Reference Figure 1 As shown, the rotating rod 7 is further connected to the second rotating shaft 31 through a synchronous transmission mechanism 8. The synchronous transmission mechanism 8 can be a transmission gear 61, which drives the rotating rod 7 to rotate synchronously while the second rotating shaft 31 rotates, or it can be a belt for transmission connection, so as to realize the intermittent feeding while crushing the material, without the need to set an additional drive mechanism for the intermittent feeding component 4.
