Description

Technical Field

[0001] This utility model relates to the technical field of rotary kiln equipment, specifically to a device for quickly cleaning accumulated material inside a rotary kiln preheater. Background Technology

[0002] Blockage in rotary kiln preheaters can cause serious problems, including: obstructed material flow, disrupting the continuity of the entire production process; reduced or even interrupted feed and discharge rates, leading to longer production cycles and a significant decrease in output per unit time; and the need for extensive cleaning and repair after blockage, further increasing downtime and reducing the effective operating time of the equipment.

[0003] When the preheater becomes clogged, airflow is obstructed, resulting in poor ventilation. To maintain production, the fan power needs to be increased to overcome the resistance, leading to increased energy consumption. Simultaneously, the prolonged residence time of materials in the preheater reduces heat exchange efficiency, requiring more fuel to maintain the rotary kiln's normal temperature, further increasing energy costs.

[0004] Blockage can cause increased internal pressure in the preheater, putting enormous stress on the equipment's structure. Prolonged high pressure can lead to production accidents such as equipment deformation and cracking. For example, components like the preheater's cyclone separator and pipes may rupture due to excessive pressure, posing a serious threat to surrounding personnel and equipment.

[0005] Blockages disrupt the thermal regime of the preheater, reducing heat exchange efficiency. Materials that are not adequately preheated within the preheater require more heat to reach the reaction temperature upon entering the rotary kiln, increasing fuel consumption and potentially affecting product quality. However, existing preheater cleaning technologies suffer from low efficiency, significantly impacting production cycle time. Utility Model Content

[0030] The working principle and beneficial effects of this utility model are as follows:

[0031] In this invention, the pusher plate is slidably disposed relative to the frame and connected to the first sliding member via a first connecting member. The pusher head is disposed at the end of the first sliding member. This design allows the pusher head to move flexibly within a large range, effectively covering material accumulation in different locations within the preheater. When cleaning accumulated material, the sliding of the pusher plate can drive the pusher head to the area where the material is accumulated. Then, under the action of the first sliding member, the pusher head can further penetrate the material, achieving a powerful push and greatly improving cleaning efficiency. Since the pusher head can be adjusted in position under the action of the first sliding member, this device can more effectively clean material accumulation in corners or irregularly shaped areas within the preheater. Compared with traditional fixed-structure cleaning devices, this adjustable pusher head can better adapt to the complex internal structure of the preheater, ensuring that the accumulated material is thoroughly removed. The combined structure of the pusher plate, the first connecting member, the first sliding member, and the pusher head can be adjusted according to rotary kiln preheaters of different sizes. Whether it is a large or small preheater, by adjusting the sliding range of the pusher plate and the stroke of the first sliding member, the pusher head can cover the entire internal space of the preheater, meeting the material cleaning needs of production equipment of different sizes and improving the versatility of the device.

[0032] Driven by the first sliding component, the pusher head can more precisely push away the accumulated material, avoiding scratches or impacts to the inner wall of the preheater caused by improper force or inaccurate positioning during the cleaning process. In long-term cleaning operations, this precise operation can extend the service life of the preheater and reduce maintenance costs and production delays due to equipment damage. The sliding of the push plate relative to the frame and the stable movement of the pusher head on the first sliding component make the cleaning process smoother. It prevents damage to the preheater structure due to severe vibration or unstable operation, ensuring the normal operation of the preheater after the accumulated material is cleaned.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Reference Figures 1-4 The first embodiment of this utility model proposes a device for quickly cleaning up accumulated material in a rotary kiln preheater, including a frame, a push plate 1 slidably disposed relative to the frame, a first connecting member 2 disposed on the push plate 1, a first sliding member 3 slidably disposed relative to the first connecting member 2, and a push head 4 disposed at the end of the first sliding member 3 for pushing up the accumulated material in the preheater.

[0044] In this embodiment, the pusher plate 1 is slidably disposed relative to the frame and connected to the first sliding member 3 via the first connecting member 2. The pusher head 4 is disposed at the end of the first sliding member 3. This design allows the pusher head 4 to move flexibly within a large range, effectively covering material accumulation in different locations within the preheater. When cleaning accumulated material, the sliding of the pusher plate 1 can drive the pusher head 4 to the area where the material is located. Then, under the action of the first sliding member 3, the pusher head 4 can further penetrate the material, achieving a powerful push and greatly improving cleaning efficiency. Since the pusher head 4 can adjust its position under the action of the first sliding member 3, the device can more effectively clean material accumulation in corners or irregularly shaped areas within the preheater. Compared with traditional fixed structure cleaning devices, this adjustable pusher head 4 can better adapt to the complex internal structure of the preheater, ensuring that the accumulated material is thoroughly removed. The combined structure of the pusher plate 1, the first connecting member 2, the first sliding member 3, and the pusher head 4 can be adjusted according to rotary kiln preheaters of different sizes. Whether it is a large or small preheater, by adjusting the sliding range of the pusher plate 1 and the stroke of the first sliding member 3, the pusher head 4 can cover the entire internal space of the preheater, meet the material cleaning needs of production equipment of different sizes, and improve the versatility of the device.

[0045] Driven by the first sliding member 3, the pusher head 4 can more precisely push the accumulated material, avoiding scratches or impacts to the inner wall of the preheater caused by improper force or inaccurate positioning during the cleaning process. In long-term cleaning operations, this precise operation can extend the service life of the preheater and reduce maintenance costs and production delays caused by equipment damage. The sliding of the pusher plate 1 relative to the frame and the stable movement of the pusher head 4 on the first sliding member 3 make the cleaning process smoother. It prevents damage to the preheater structure due to severe vibration or unstable operation, ensuring the normal operation of the preheater after cleaning the accumulated material.

[0046] Furthermore, the first connector 2 has a sliding cavity 201, and the first slider 3 is slidably disposed within the sliding cavity 201.

[0047] In this embodiment, the first connecting member 2 has a sliding cavity 201, in which the first sliding member 3 is slidably disposed. This design provides a stable sliding track for the first sliding member 3, enabling it to move precisely along a predetermined path when pushing the pusher head 4 to clean up accumulated material. In the case of limited space and complex environment within the rotary kiln preheater, this stable sliding structure ensures that the pusher head 4 accurately reaches the material accumulation position, avoiding any impact on the cleaning effect due to shaking or deviation.

[0048] The presence of the sliding cavity 201 makes the movement of the first sliding member 3 more reliable. During the process of cleaning accumulated material, various resistances and interferences may be encountered. The sliding cavity 201 can restrict the degree of freedom of the first sliding member 3, preventing it from unexpectedly bending or deforming under stress. This allows operators to operate the device with greater confidence, improving the reliability and stability of the cleaning work.

[0049] The sliding cavity 201 serves to protect the first sliding member 3. Inside the preheater, accumulated material may contain hard particles or impurities, which could cause wear to the first sliding member 3 during cleaning. By placing the first sliding member 3 within the sliding cavity 201, direct contact with the accumulated material and other external objects is avoided, reducing the risk of wear and damage. Furthermore, the sliding cavity 201 prevents dust and moisture from entering the connection 601 between the first sliding member 3 and the first connecting member 2, extending the service life of the device. By protecting the first sliding member 3, the sliding cavity 201 contributes to improving the overall durability of the device. Reduced wear and damage during long-term use means less frequent maintenance and component replacement, lowering maintenance costs. Simultaneously, a durable device better meets production needs, ensuring the normal operation of the rotary kiln preheater.

[0050] Furthermore, the first sliding member 3 has a second locking part 301, which is arranged in a plurality of ways, and also includes a first swing member 5, which is swing-arranged in the sliding cavity 201. The first swing member 5 has a first locking part 501. After the first swing member 5 swings, the first locking part 501 engages with or disengages from the second locking part 301.

[0051] In this embodiment, several second locking portions 301 arranged on the first sliding member 3 cooperate with the first locking portions 501 on the first swing member 5. When the first swing member 5 swings, the first locking portions 501 and the second locking portions 301 engage, effectively fixing the first sliding member 3 in a specific position. During the process of cleaning the accumulated material inside the rotary kiln preheater, this engaging structure ensures that the pusher head 4 remains stable in the required position, allowing for more precise cleaning of the accumulated material. When the pusher plate 1 resets, the pusher head 4 will not retract, thus reducing the cleaning area. Through the engaging mechanism, the cleaning range of the pusher head 4 is extended, reducing the labor intensity of the workers.

[0052] During the process of cleaning up accumulated material, various unexpected situations may occur, such as equipment vibration and external impact. The engagement between the first locking part 501 and the second locking part 301 can prevent the first sliding member 3 from accidentally sliding in these situations, thereby avoiding injury to the operator or preheater equipment caused by the pusher head 4. This safety protection function is crucial for ensuring the safety of the operator and the normal operation of the equipment.

[0053] Furthermore, the first swing member 5 is a first pawl, and the second locking part 301 is a first ratchet, with the first pawl locking onto the first ratchet.

[0054] In this embodiment, the first swinging member 5 is designed as a first pawl, and the second locking part 301 is a first ratchet. This combination forms a one-way locking structure. During the process of cleaning the accumulated material in the rotary kiln preheater, the first pawl is locked on the first ratchet, which can effectively prevent the first sliding member 3 from sliding backward. When the pusher 4 pushes the accumulated material, even if it is subjected to the reaction force of the accumulated material, the first pawl can firmly lock the first ratchet, ensuring that the first sliding member 3 will not retract unexpectedly, thus ensuring the stability and safety of the cleaning operation. The one-way locking function makes the operator more at ease when using the device. There is no need to worry about the first sliding member 3 becoming unstable during operation, so that the operator can focus more on the material cleaning operation. This reliability is especially important for long-term, high-intensity cleaning work, which can reduce downtime caused by equipment failure and improve production efficiency. In the rotary kiln preheater, the distribution and accumulation of accumulated material can be very complex. Sometimes it is necessary to continuously apply pushing force to clean the accumulated material, and the one-way locking pawl and ratchet structure meets this need. Regardless of the resistance from the accumulated material, the first pawl ensures that the first sliding member 3 continues to advance until the cleaning task is completed. This adaptability allows the device to handle various material accumulation conditions, improving cleaning effectiveness and work efficiency.

[0055] Furthermore, the first sliding member 3 has a sliding groove 302 and also includes a second sliding member 6. The second sliding member 6 is slidably disposed in the sliding groove 302, and the second swing member 7 is swing disposed in the sliding groove 302. After the second swing member 7 swings, the second swing member 7 engages with or disengages from the second sliding member 6.

[0056] In this embodiment, the first sliding member 3 is provided with a groove 302, in which the second sliding member 6 can slide, providing more adjustment dimensions for the cleaning device. When cleaning the accumulated material in the rotary kiln preheater, the position and angle of the pusher head 4 can be further precisely controlled by adjusting the position of the second sliding member 6 in the groove 302 according to the specific location and shape of the accumulated material. This multi-dimensional sliding adjustment function allows the cleaning device to adapt more flexibly to different material accumulation conditions and improves cleaning efficiency. The setting of the second swing member 7 makes the control of the second sliding member 6 more precise. When the second swing member 7 swings and engages or disengages with the second sliding member 6, it can quickly lock and unlock the second sliding member 6. When it is necessary to fine-tune the position of the pusher head 4, the operator can precisely control the movement of the second sliding member 6 through the second swing member 7, thereby achieving fine adjustment of the pusher head 4. This allows the pusher head 4 to slide in one direction, further increasing the cleaning range of the pusher head 4.

[0057] During the process of cleaning accumulated material, various external forces may be encountered, such as the reaction force of the accumulated material and equipment vibration. The engagement between the second swing member 7 and the second sliding member 6 prevents the second sliding member 6 from sliding accidentally in these situations, thereby ensuring the stability of the pusher head 4 and guaranteeing the smooth progress of the cleaning work. This stable structural design can improve the reliability of the device and reduce cleaning failures or damage to the inner wall of the preheater caused by accidental sliding.

[0058] When maintenance or repair of the cleaning device is required, the design of the second sliding member 6 and the second swing member 7 makes disassembly and replacement more convenient. Operators can easily remove the second sliding member 6 from the slide groove 302 by swinging the second swing member 7 for inspection, repair, or replacement. This maintenance-friendly design reduces equipment downtime and improves production efficiency.

[0059] Because of the high flexibility and adjustability of the design of the second sliding member 6 and the second swing member 7, this cleaning device can adapt to rotary kiln preheaters of different specifications. Whether the preheater is large or small, the cleaning needs of preheaters of different sizes and shapes can be met by adjusting the position and state of the second sliding member 6 and the second swing member 7. This versatility allows the device to function effectively in various production environments, saving companies equipment investment costs.

[0060] Furthermore, after the first slider 3 slides, it slides into or out of the sliding cavity 201. The second slider 6 has a connecting part 601. The second slider 6 is configured such that after the first slider 3 slides out of the sliding cavity 201, the connecting part 601 engages with the first locking part 501. When the first connecting part 2 slides in a direction away from the push head 4, the second slider 6 slides relative to the first slider 3.

[0061] In this embodiment, after the first sliding member 3 slides out of the sliding cavity 201, the connecting part 601 of the second sliding member 6 engages with the first locking part 501. The different sliding states and engagement relationships of the first sliding member 3 and the second sliding member 6 enable the cleaning device to perform multi-stage operations. During the cleaning of accumulated material in the rotary kiln preheater, the pusher 4 can first be pushed to a certain position by sliding the first sliding member 3. Then, as needed, the first sliding member 3 can slide out, causing the connecting part 601 of the second sliding member 6 to engage with the first locking part 501, and then further operations can be performed. This multi-stage operation can better adapt to complex material accumulation situations and improve cleaning efficiency.

[0062] After the first sliding member 3 slides out of the sliding cavity 201, the connecting part 601 of the second sliding member 6 engages with the first locking part 501, effectively preventing accidental sliding of the first sliding member 3 and the second sliding member 6 during operation. The different sliding states and locking relationships of the first sliding member 3 and the second sliding member 6 make it easier for operators to adjust and maintain the cleaning device. Through the two-stage sliding of the first sliding member 3 and the second sliding member 6, the cleaning efficiency and cleaning area are effectively improved, and the device better matches the reciprocating pushing state of the pusher head 4 inside the preheater, enhancing the adaptability of the equipment.

[0063] Furthermore, the second swing member 7 is a second pawl, and the second sliding member 6 has a third locking part 602, which is a second ratchet, and the second pawl is locked on the second ratchet.

[0064] In this embodiment, the second pawl engages with the second ratchet bar, forming a one-way locking mechanism. During the cleaning of accumulated material inside the rotary kiln preheater, this mechanism effectively prevents the second sliding member 6 from sliding backward under external force. This ensures that the pusher head 4 remains in the desired position, continuously and stably pushing the accumulated material, improving cleaning efficiency and effectiveness. The one-way locking function provides operators with a more stable operating experience. During cleaning, there is no need to worry about the second sliding member 6 accidentally retracting, allowing operators to focus more intently on controlling the position and force of the pusher head 4, reducing operational errors and improving work safety.

[0065] The pawl and ratchet have a relatively simple structure, offering high strength and wear resistance. They can withstand significant forces and frequent friction during long-term use without easily becoming damaged. Compared to other complex locking structures, the design of the second pawl and ratchet reduces wear between components, extending the device's lifespan. Due to its simple and durable structure, maintenance costs are relatively low. In daily use, frequent repairs and component replacements are unnecessary, reducing equipment downtime and maintenance costs. Simultaneously, the reliable locking mechanism reduces safety hazards caused by component damage.

[0066] Furthermore, the pusher head 4 has a shovel section 401 and also includes a sliding plate 8, which is slidably disposed on the pusher head 4 and located above the shovel section 401.

[0067] In this embodiment, a shovel section 401 is provided on the pusher head 4 to push the accumulated material in the preheater, and a sliding plate 8 is slidably arranged above the shovel section 401. During the cleaning process, the sliding plate 8 can assist in shoveling material as the pusher head 4 advances. When the shovel section 401 of the pusher head 4 contacts the accumulated material, the sliding plate 8 can slide above the shovel section 401 as the pusher head 4 advances, generating additional pressure on the accumulated material, making it easier to shovel and push. This auxiliary shoveling function can improve shoveling efficiency and reduce cleaning time. The presence of the sliding plate 8 allows the cleaning device to better adapt to different states of accumulated material. For looser accumulated material, the sliding plate 8 can help compact the material, making it easier to shovel; for harder accumulated material, the sliding plate 8 can increase the shoveling force and improve the cleaning effect. This adaptability allows the cleaning device to perform well in the face of various accumulated material conditions.

[0068] During the process of clearing accumulated material, the scraping part 401 of the pusher head 4 comes into direct contact with the accumulated material, making it susceptible to wear and damage. The sliding plate 8 can protect the scraping part 401 to a certain extent, reducing the direct impact and wear it receives. When encountering hard accumulated material or obstacles, the sliding plate 8 can make contact with the accumulated material first, dispersing some of the impact force, thereby reducing the risk of damage to the scraping part 401. In addition, the sliding plate 8 can also prevent sharp objects in the accumulated material from directly scratching the scraping part 401, extending the service life of the pusher head 4.

[0069] When the pusher plate 1 retracts, the material on the shovel section 401 exerts pressure on the pusher head 4, effectively preventing it from retracting. This mechanism is crucial in cleaning accumulated material inside the rotary kiln preheater. In complex cleaning operations, the stable advancement and position maintenance of the pusher head 4 are paramount. This anti-retraction function ensures that the pusher head 4 remains in an effective working position throughout the cleaning process, avoiding incomplete cleaning or the need for readjustment due to pusher head 4 retraction, thus improving the overall stability of the cleaning operation. When dealing with accumulated material of varying density and hardness, the pusher head 4 requires a continuous and stable pushing force. Through the pressure exerted on the pusher head 4 by the material in the shovel section 401, even under conditions that might cause changes in the force on the pusher head 4, such as the retraction of the pusher plate 1, a continuous cleaning force on the accumulated material can still be maintained, ensuring the continuity and efficiency of the cleaning operation. This stable cleaning force can better handle various complex material accumulation situations and improve the cleaning effect.

[0070] Furthermore, the bottom of the shovel section 401 abuts against the bottom of the preheater, and the shovel section 401 has a shovel slope 402.

[0071] In this embodiment, the bottom of the shovel section 401 abuts against the bottom of the preheater, ensuring maximum contact with the accumulated material during cleaning. This allows for more effective shoveling of the accumulated material from the bottom of the preheater, preventing material residue. In actual operation, this tight contact allows the shovel section 401 to penetrate deep into the accumulated material layer, improving the efficiency and thoroughness of shoveling. The shovel section 401 has a shovel ramp 402, which helps guide the accumulated material to flow in the direction of movement of the pusher 4. As the pusher 4 moves forward, the accumulated material is smoothly pushed along the shovel ramp 402, reducing resistance during the shoveling process. The accumulation pattern of the material in a rotary kiln preheater can vary. The abutment of the bottom of the shovel section 401 against the bottom of the preheater and the design of the shovel ramp 402 can accommodate different material thicknesses and accumulation angles. Whether the accumulated material layer is thin or thick, flat or inclined, this design effectively cleans it, improving the versatility and adaptability of the device.

[0072] The design of the scraper section 401 also plays a role in handling accumulated materials of varying hardness. When encountering harder accumulated materials, the abutment at the bottom of the scraper section 401 provides greater scraping force, while the scraping ramp 402 reduces damage to the scraper section 401 by dispersing the force. For softer accumulated materials, the scraping ramp 402 can better guide the flow of the accumulated materials, improving cleaning efficiency.

[0073] When the bottom of the shovel section 401 comes into contact with the bottom of the preheater, it reduces wear and scratches on the preheater bottom. During the cleaning of accumulated material, direct hard collisions between the shovel section 401 and the preheater bottom are avoided, reducing the risk of damage to the preheater equipment. At the same time, the smooth design of the shovel slope 402 also reduces friction on the preheater bottom during the shoveling process, extending the preheater's service life.

[0074] Furthermore, it also includes a first elastic member 9, one end of which acts on the sliding cavity 201 and the other end of which acts on the first swing member 5, providing a force for the first locking part 501 to approach the second locking part 301; a second elastic member 10, one end of which acts on the sliding groove 302 and the other end of which acts on the second swing member 7, providing a force for the second swing member 7 to approach the second sliding member 6; and a third elastic member 11, one end of which acts on the push head 4 and the other end of which acts on the sliding plate 8, providing a force for the sliding plate 8 to move away from the push head 4.

[0075] In this embodiment, one end of the first elastic member 9 acts on the sliding cavity 201, and the other end acts on the first swing member 5, providing a force to bring the first locking part 501 close to the second locking part 301. During the process of cleaning the accumulated material inside the rotary kiln preheater, this elastic force ensures that the first locking part 501 remains in close contact with the second locking part 301, enhancing the stability of the locking mechanism. Even when the device is subjected to vibration or external interference, the first elastic member 9 can keep the first swing member 5 in the locking position, preventing the first sliding member 3 from accidentally sliding and ensuring the smooth progress of the cleaning work.

[0076] The second elastic element 10 acts on the slide groove 302 at one end and on the second swing element 7 at the other end, providing a force to pull the second swing element 7 closer to the second sliding element 6. Similarly, this elastic force makes the engagement between the second swing element 7 and the second sliding element 6 more secure, improving the stability of the device. During operation, the second elastic element 10 ensures that the second swing element 7 can quickly and accurately engage with the second sliding element 6 when needed, improving work efficiency.

[0077] The third elastic element 11 acts on the pusher head 4 at one end and on the sliding plate 8 at the other end, providing a force to push the sliding plate 8 away from the pusher head 4. During material cleaning, the sliding plate 8 can automatically adjust its position according to the thickness and hardness of the accumulated material. When encountering thicker or harder material, the sliding plate 8 can move backward under the action of the third elastic element 11, increasing the pressure on the material and improving the cleaning effect. When encountering thinner or softer material, the sliding plate 8 can maintain an appropriate position under the action of the third elastic element 11, avoiding excessive compression of the material and protecting the inner wall of the preheater. When the material reaches the discharge port, the sliding plate 8 pushes the material away from the shoveling section 401 under the action of the third elastic element 11.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
