Description

Technical Field

[0001] The invention relates to the technical field of cement production equipment, in particular to a low-loss and high-wear-resistant raw material crusher. Background Art

[0002] Cement: A powdered, hydraulically hardening inorganic cementitious material. When mixed with water, it forms a slurry that hardens in air or, even better, in water, firmly bonding materials like sand and stone. Early lime-pozzolana mixtures are very similar to modern lime-pozzolana cement. Using it to bond crushed stone concrete yields high strength after hardening and resistance to erosion by fresh or salt water. It has long been a key cementitious material used extensively in civil engineering, water conservancy projects, and other fields.

[0003] In the cement production process, raw materials need to be crushed. The raw material crushing equipment in the existing technology usually uses crushing rollers to directly crush the raw materials. This crushing method puts a large force on the crushing roller, resulting in high power consumption of the crushing equipment and easy damage to the crushing roller.

[0004] Therefore, the crushing equipment in the prior art has technical problems of high energy consumption and easy damage of the crushing roller. Summary of the Invention

[0005] The present invention provides a low-loss and highly wear-resistant raw material crusher, which solves the technical problems of high energy consumption and easy damage of crushing rollers in the prior art crushing equipment.

[0006] Some implementation plans adopted to solve the above technical problems include:

[0007] A low-loss and high-wear-resistant raw material crusher comprises a frame and a crushing assembly arranged on the frame;

[0008] The crushing assembly includes a slewing ring rotatably connected to the frame, and a crushing space is formed in the slewing ring;

[0009] A thrower and a crusher located below the thrower are provided in the crushing space, and a filter hole is provided on the rotary ring, and the filter hole passes through the rotary ring;

[0010] The frame is further provided with a feeding pipe, which is communicated with the crushing space;

[0011] Wherein, the raw material enters the crushing space through the feed pipe;

[0012] The raw material entering the crushing space enters the thrower under the action of gravity, and the thrower throws the raw material so that the raw material hits the rotary ring and is crushed to obtain intermediate material;

[0013] The intermediate material enters the rotating ring under the action of gravity, and the rotating ring drives the intermediate material to rotate. A portion of the intermediate material driven by the rotating ring is thrown again by the thrower and hits the rotating ring, and the other portion of the intermediate material driven by the rotating ring enters the crusher under the action of gravity;

[0014] The intermediate material crushed by the crusher is discharged from the crushing space through the filter hole, and the filtered material of the filter hole is driven to rotate again by the rotary ring and is thrown again by the thrower.

[0015] Preferably, the inner wall of the slewing ring is provided with a particle board, and the particle board is arranged along the diameter direction of the slewing ring. The frame is provided with a third driver for driving the slewing ring to rotate.

[0016] Preferably, a material retaining ring is provided at both ends of the rotating ring, and the material retaining ring protrudes from the inner wall of the rotating ring toward the middle of the rotating ring. The rotating ring, the material retaining ring and the particle board cooperate to form a receiving groove, and the intermediate material enters the receiving groove under the action of gravity.

[0017] Preferably, a blade is provided at one end of the particle board away from the slewing ring, and the blade and the particle board are an integrated structure.

[0018] Preferably, the thrower includes a throwing shaft, the throwing shaft is provided with blades, the blades and the throwing shaft are an integrated structure, and the frame is further provided with a first driver for driving the throwing shaft to rotate.

[0019] Preferably, the blade is provided with a buffer layer, the buffer layer is bonded to the blade, and the buffer layer is a rubber layer.

[0020] Preferably, there are at least two throwing shafts, each of which is driven by an independent first driver, and each of which is provided with blades, and each of which has an independent rotational speed.

[0021] Preferably, the crusher includes a crushing roller, which is rotatably connected to the frame. There are two crushing rollers, and a crushing channel is formed between the two crushing rollers.

[0022] Preferably, the crushing roller is driven by a second driver, which drives one of the crushing rollers, and a transmission mechanism is provided between the two crushing rollers.

[0023] Preferably, the crushing roller is provided with crushing teeth, the crushing teeth are welded to the crushing roller, and the crushing teeth are provided with a wear-resistant layer.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. By setting up a thrower, the raw material that enters the thrower during the rotation process will be thrown out, and the thrown raw material collides with the rotating ring. Since the thrown raw material has a certain linear velocity, the raw material collides with the rotating ring and generates impact, so that the raw material is broken due to the collision. The broken raw material is then broken by the crusher. Therefore, the raw material crushed by the crusher is the raw material that has been crushed by collision. The crusher does not require large power, which reduces the power consumption of the crusher and improves the crushing efficiency.

[0026] 2. By setting up a thrower, the thrower throws the raw material, causing the raw material to collide with the crushing ring and be broken. There is no need to directly squeeze the raw material to break it. Therefore, the thrower does not require a large power, further reducing the power consumption of the crusher.

[0027] 3. By setting up a rotary ring, the rotary ring can transfer the filtered material from the filter hole to the top of the thrower again. After being transferred to the top of the thrower, the filtered material from the filter hole is processed by the thrower and crusher again, forming a circular process, thereby improving the crushing effect of the crusher, and the materials discharged from the filter hole are all materials that meet the requirements.

[0042] The specific embodiment shown below is intended to be a description of the various configurations of the subject technology of the present invention, and is not intended to represent that the subject technology of the present invention can be put into practice. The specific embodiment includes that specific details are intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and apparent to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be put into practice without these specific details.

[0043] It will be understood that, herein, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another entity or operation, and are not intended to express or imply any actual relationship or order between these entities or operations.

[0044] The terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0045] Reference Figures 1 to 6 As shown, a low-loss and high-wear-resistant raw material crusher includes a frame 1 and a crushing assembly 2 arranged on the frame 1;

[0046] The crushing assembly 2 includes a slewing ring 21 rotatably connected to the frame 1 , and a crushing space 211 is formed in the slewing ring 21 ;

[0047] The crushing space 211 is provided with a thrower 22 and a crusher 23 located below the thrower 22. The rotary ring 21 is provided with a filter hole 212, and the filter hole 212 passes through the rotary ring 21.

[0048] The frame 1 is further provided with a feed pipe 3, which is communicated with the crushing space 211;

[0049] The raw material enters the crushing space 211 through the feed pipe 3;

[0050] The raw material entering the crushing space 211 enters the thrower 22 under the action of gravity. The thrower 22 throws the raw material so that the raw material hits the rotary ring 21 and is crushed to obtain intermediate material.

[0051] The intermediate material enters the rotating ring 21 under the action of gravity, and the rotating ring 21 drives the intermediate material to rotate. A portion of the intermediate material driven by the rotating ring 21 is thrown again by the thrower 22 and hits the rotating ring 21. The other portion of the intermediate material driven by the rotating ring 21 enters the crusher 23 under the action of gravity.

[0052] The intermediate material crushed by the crusher 23 is discharged from the crushing space 211 through the filter hole 212 , and the filtered material in the filter hole 212 is driven to rotate again by the rotary ring 21 and is thrown again by the thrower 22 .

[0053] Specifically, the thrower 22 is used to throw the raw material so that the raw material obtains a higher linear velocity, thereby causing the raw material to collide with the rotary ring 21 to generate an impact, and the raw material is broken under the impact.

[0054] The thrower 22 does not need to directly squeeze the raw material to break it. Therefore, the thrower 22 does not need to have a large power. It only needs to make the raw material have a certain linear speed when throwing the raw material.

[0055] That is, the throwing shaft 221 of the throwing device 22 only needs to have a certain rotation speed.

[0056] Because the raw material is first impacted and crushed before entering the crusher 23, the particles of the intermediate material entering the crusher 23 are smaller, which means that the crusher 23 does not need to have a large power, thereby reducing the power consumption of the crusher. In addition, because the diameter of the intermediate material entering the crusher 23 is small, the crusher 23 is not easily worn or damaged.

[0057] The rotary ring 21 is in a rotating state during use, and can continuously convey the filtered material of the filter holes 212 to a higher position, so that the raw material in the crushing space 211 is cyclically crushed, thereby improving the crushing quality.

[0058] Reference Figures 2 to 6 As shown, in some embodiments, the inner wall of the slewing ring 21 is provided with a particle board 213, and the particle board 213 is provided along the diameter direction of the slewing ring 21. The frame 1 is provided with a third driver for driving the slewing ring 21 to rotate.

[0059] The third driver may be a motor, which drives the gear disposed on the frame 1 to rotate, and the slewing ring 21 is provided with a gear ring engaged with the gear.

[0060] The frame 1 is also provided with intermediate wheels, which are rotatably connected to the frame 1 and are used to support the slewing ring 21. The intermediate wheels are evenly distributed along the circumference of the slewing ring 21. The number of intermediate wheels is not limited and can be reasonably determined as needed.

[0061] In some embodiments, a retaining ring 214 is further provided at both ends of the rotating ring 21, and the retaining ring 214 protrudes from the inner wall of the rotating ring 21 toward the middle of the rotating ring 21. The rotating ring 21, the retaining ring 214, and the particle board 213 cooperate to form a receiving groove 215, and the intermediate material enters the receiving groove 215 under the action of gravity.

[0062] When the slewing ring 21 rotates, the opening of the receiving groove 215 rotates to tilt downward, and the raw material with a larger volume in the receiving groove 215 slides out of the receiving groove 215 first, and the raw material with a smaller volume in the receiving groove 215 slides out of the receiving groove 215 later. After the raw material with a smaller volume slides out of the receiving groove 215, it falls to the crusher 23 under the action of gravity.

[0063] A blade is provided at one end of the particle board 213 away from the slewing ring 21 , and the blade and the particle board 213 are an integrated structure.

[0064] The retaining ring 214, the rotating ring 21 and the chipping plate 213 are an integrated structure. The raw material thrown by the ejector 22 collides with the blade of the chipping plate 213, making the raw material easier to break.

[0065] In some embodiments, the ejector 22 includes a ejector shaft 221 , the ejector shaft 221 is provided with blades 222 , the blades 222 and the ejector shaft 221 are an integrated structure, and the frame 1 is further provided with a first driver that drives the ejector shaft 221 to rotate.

[0066] The blade 222 is provided with a buffer layer, which is bonded to the blade 222 and is a rubber layer.

[0067] In some embodiments, there are at least two throwing shafts 221 , each of which is driven by an independent first driver, and each of which is provided with a blade 222 , and each of which has an independent rotation speed.

[0068] When the linear velocity of the raw meal or the filtered material from the filter holes 212 is high, the raw meal or the filtered material from the filter holes 212 may collide with the rotary ring 21 multiple times within the crushing space 211. Therefore, the path of the raw meal or the filtered material from the filter holes 212 within the crushing space 211 is uncertain. By providing two throwing shafts 221, the raw meal or the filtered material from the filter holes 212 can be thrown multiple times, thereby optimizing the crushing effect.

[0069] Reference Figures 2 to 6 As shown, in some embodiments, the crusher 23 includes a crushing roller 231 , and the crushing roller 231 is rotatably connected to the frame 1 . There are two crushing rollers 231 , and a crushing channel is formed between the two crushing rollers 231 .

[0070] The crushing rollers 231 are driven by a second driver, and the second driver drives one of the crushing rollers 231 . A transmission mechanism is provided between the two crushing rollers 231 .

[0071] The second driver and the first driver can both be motors, and the first driver, the second driver and the third driver can all be fixed to the frame 1 by screws.

[0072] The transmission mechanism may be a gear transmission assembly, which includes a driving gear and a driven gear. One crushing roller 231 is provided with a driving gear, and the other crushing roller 231 is provided with a driven gear meshing with the driving gear.

[0073] In some embodiments, the crushing roller 231 is provided with crushing teeth, the crushing teeth are welded to the crushing roller 231, and the crushing teeth are provided with a wear-resistant layer.

[0074] The wear-resistant layer can be plated on the crushing teeth.

[0075] In some embodiments, the rotation speed of the throwing shaft 221 is determined according to the strength of the raw material, that is, the rotation speed of the throwing shaft 221 needs to ensure that the raw material thrown out by the thrower 22 is broken under the impact when it collides with the rotating ring 21, thereby achieving the initial crushing of the raw material.

[0076] The raw meal refers to the raw meal that enters the crushing space 211 through the feed pipe 3 and the raw meal formed by the filtered material of the filter holes 212 conveyed by the rotary ring 21.

[0077] The above describes the subject technical solution and corresponding details of the present invention. It can be understood that the above description is only some implementation plans of the subject technical solution of the present invention, and some details may be omitted during its specific implementation.

[0078] In addition, in some embodiments of the above invention, multiple embodiments may be implemented in combination. Due to space limitations, various combination schemes are not listed one by one. Those skilled in the art can freely combine and implement the above embodiments as needed in specific implementation to obtain a better application experience.

[0079] When implementing the subject technical solution of the present invention, those skilled in the art can obtain other detailed configurations or drawings based on the subject technical solution of the present invention and the drawings. Obviously, these details still fall within the scope covered by the subject technical solution of the present invention without departing from the subject technical solution of the present invention.
