Description

Technical Field

[0001] This invention relates to the field of cement manufacturing technology, specifically to grinding equipment and production process for low-carbon monolithic cementitious materials based on particle size distribution technology. Background Technology

[0002] With increasingly stringent standards for large-scale infrastructure and architectural design in China, the application scenarios for UHPC and RPC concrete are expanding. The cement, fly ash, mineral powder, and silica fume used in these high-performance concretes are all commercially available products. In particular, mineral powder products that meet national standards often fail to meet the mix design requirements of UHPC and RPC concrete, necessitating the use of more expensive silica fume as an admixture. Furthermore, the so-called ultrafine powders on the market are often adulterated, with issues beyond fineness, such as blast furnace slag content and loss on ignition. Silica fume, a submicron-sized product with an average particle size of 0.1-0.3 mm, is highly prone to agglomeration. Mineral powder typically has a specific surface area of ​​420-450 m² / kg and an average particle size of 15 mm; Grade I fly ash has a specific surface area of ​​300 m² / kg and an average particle size of 25 mm; and cement has a specific surface area of ​​350 m² / kg and an average particle size of around 20 mm. When producing concrete using the four cementitious materials mentioned above, general-purpose mixing equipment struggles to achieve uniform mixing. Materials with smaller proportions are even more difficult to distribute evenly, failing to fully realize their intended properties. To achieve the design objectives, the proportions of these materials must be increased accordingly, leading to material waste and increased costs. Furthermore, in existing production processes, the dust collector often requires shutdown for repairs due to filter plate damage during dust collection. Summary of the Invention

[0073] In this embodiment, a dust collector 1 is designed, the main body of the dust collector 1 is a shell 101, and a closed cavity 102 is formed inside the shell 101 to provide space for dust collection and filtration. A partition 117 is arranged in the cavity 102, which divides the cavity 102 into an upper cavity 103 and a lower cavity 104. A plurality of through holes 108 are arranged on the partition 117 for the filter core to pass through, and the cover plate on the partition 117 can swing to control the opening and closing of the through holes 108, thereby avoiding dust escape when the filter plate 109 is not replaced. The filter plate 109 is located in the lower cavity 104 and can slide, and its two sides are respectively a dust gas inlet 105 and a clean gas outlet 106. The sliding design of the filter plate 109 enables it to pass through the through hole 108 on the partition 117 and enter the upper cavity 103, facilitating the replacement and cleaning of the filter plate 109. The filter plate 109 is designed with a clamping groove 110, and the clamping piece 111 is swingingly arranged in the lower cavity 104. The swinging of the clamping piece 111 can realize the clamping and swinging out of the filter plate 109. This design ensures the stable fixation of the filter plate 109 during use, and also facilitates the disassembly and replacement of the filter plate 109. The replacement clamp 112 is located in the upper cavity 103 and can move.

In summary, through the innovative design of the dust collector 1, not only the dust collection efficiency is improved, but also the filter plate 109 is replaced conveniently. Compared with the dust collector 1 of the prior art, the advantage of the design of the partition 117 is that the dust in the lower cavity 104 is not easy to escape to the upper cavity 103 under the action of the airflow. The design of the partition 117 further avoids the escape of dust.

The arc-shaped clamping piece 111 and the arc-shaped clamping groove 110 are concentrically arranged, and the radii are equal, which facilitates the clamping of the arc-shaped clamping piece 111. Compared with other shapes of clamping pieces 111, the arc-shaped clamping piece 111 can avoid the interference phenomenon between the clamping piece 111 and the clamping groove 110 when the clamping piece 111 swings. The movement of the replacement clamp 112 enables the filter plate 109 to be replaced without stopping, and compared with the prior art, the design of the filter plate 109 enables the filter plate 109 to be replaced quickly without stopping when it is blocked or damaged, which improves the production efficiency and reduces the downtime.

[0074] Further, the first screw rod 2 is rotationally arranged at the upper portion of the upper cavity 103, the moving piece 3 is threadedly arranged on the first screw rod 2, the moving piece 3 is provided with the first guide hole 301, the first guide rod 4 is arranged in the upper cavity 103 and penetrates the first guide hole 301, the second screw rod 5 is rotationally arranged on the moving piece 3 and is perpendicular to the first screw rod 2, the lifting piece 6 is threadedly arranged on the second screw rod 5, the second screw rod 5 is provided with the second guide hole 601, the second guide rod 7 is arranged on the moving piece 3 and is parallel to the second screw rod 5, the second guide rod 7 penetrates the second guide hole 601, and the rotating piece 8 is rotationally arranged on the lifting piece 6, and the replacement clamp 112 is arranged on the rotating piece 8.

[0075] In the embodiment, the first screw rod 2 is rotationally arranged at the upper portion of the upper cavity 103, the moving piece 3 is threadedly arranged on the first screw rod 2, and along with the rotation of the first screw rod 2, the moving piece 3 moves linearly along the axis direction of the first screw rod 2. The moving piece 3 is also designed with the first guide hole 301 for the guidance of the first guide rod 4. The first guide rod 4 penetrates the first guide hole 301 of the moving piece 3, limits the moving direction of the moving piece 3, ensures the linear movement of the moving piece 3 along the axis of the first screw rod 2, and improves the precision and stability of the movement. The second screw rod 5 is arranged perpendicularly to the first screw rod 2 and is rotationally arranged on the moving piece 3. The lifting piece 6 is threadedly arranged on the second screw rod 5, and along with the rotation of the second screw rod 5, the lifting piece 6 moves along the axis direction of the second screw rod 5 to realize the lifting in the vertical direction. The second guide rod 7 is arranged parallel to the second screw rod 5 and penetrates the second guide hole 601 of the lifting piece 6, which is used to limit the moving direction of the lifting piece 6, ensure the vertical movement of the lifting piece 6 only along the axis direction of the second screw rod 5, and improve the stability and precision of the lifting process. The rotating piece 8 is rotationally arranged on the lifting piece 6, and the replacement clamp 112 is arranged on the rotating piece 8. Through the rotation of the rotating piece 8, the direction of the replacement clamp 112 can be adjusted to facilitate the alignment of the filter plate 109, realize the accurate clamping and replacement of the filter plate 109.

Compared with the commonly used mechanical arm, the use of the screw rod can avoid the damage of the equipment caused by dust, so that the failure rate of the equipment is lower. Through the design of the screw rod, the movement and positioning of the equipment are more accurate, the precision of the equipment is improved, and the existing dust collector 1 or dust remover adopts the method of replacing the filter plate 109 during shutdown. Through the design of the screw rod, the replacement of the filter plate 109 without shutdown is realized, which is convenient for the maintenance of the dust collector 1 by the operator.

[0076] Further, the third screw rod 9 is rotationally arranged in the upper cavity 103 and located below the first screw rod 2, and the blocking piece 10 is movably arranged in the upper cavity 103 and threadedly arranged on the third screw rod 9. After the blocking piece 10 moves, the blocking piece 10 pushes the filter plate 109 on the replacement clamp 112, the replacement clamp 112 and the rotating piece 8 rotate until the filter plate 109 is horizontal, and then the blocking piece 10 moves synchronously with the moving piece 3.

[0077] In this embodiment, the third screw rod 9 is rotationally arranged in the upper cavity 103 and located below the first screw rod 2. This design provides a power source for the movement of the blocking piece 10. The movement distance and speed of the blocking piece 10 can be accurately controlled through the rotation of the third screw rod 9. The blocking piece 10 is threadedly arranged on the third screw rod 9 and can move with the rotation of the third screw rod 9. When the blocking piece 10 moves, it can contact and push the filter plate 109 on the replacement clamp 112, thereby driving the replacement clamp 112 and the rotating piece 8 to rotate and change their positions and postures. When the blocking piece 10 pushes the replacement clamp 112 and the filter plate 109, the rotation of the rotating piece 8 and the lifting or movement of the moving piece 3 can gradually adjust the filter plate 109 from the vertical state to the horizontal position. This process is automatically completed without manual intervention, which improves the efficiency and safety of replacing the filter plate 109. After the filter plate 109 is adjusted to the horizontal position, the blocking piece 10 and the moving piece 3 start to move synchronously. This means that the filter plate 109 in the horizontal position can be more stably controlled, which is convenient for subsequent movement and replacement operations. This design ensures smooth transition of the filter plate 109 during the entire replacement process and avoids unnecessary shaking or displacement. To avoid the blocking piece 10 from swinging along the circumference of the third screw rod 9 during movement, one end of the blocking piece 10 abuts against the inner wall of the upper cavity 103, and a plurality of wheels are arranged at the abutting position of the blocking piece 10 and the inner wall of the upper cavity 103 to reduce the friction between the blocking piece 10 and the inner wall of the upper cavity 103. In summary, through the innovative design of the third screw rod 9 and the blocking piece 10, the automatic horizontal adjustment of the filter plate 109 during the replacement process is realized, which not only simplifies the operation steps but also improves the automation level and operation safety of the equipment.

[0078] Further, the transmission member is movably arranged on the partition plate 117, the transmission member is provided with tooth portions on both sides and the upper side, the first gear 12 is arranged at the end of the clamping piece 111, the first gear 12 is meshingly arranged with the tooth portions on both sides of the transmission member, the second gear 13 is rotationally arranged on the partition plate 117, the second gear 13 is meshingly arranged with the tooth portions on the upper side of the rotating piece 8, the first bevel gear 14 is coaxially arranged with the second gear 13, the second bevel gear 15 is arranged at the end of the cover plate, and the cover plate and the clamping piece 111 synchronously swing after the transmission member moves.

[0079] In this embodiment, the transmission member is movably arranged on the partition plate 117, and the two sides and the upper side thereof are provided with tooth portions. This design enables the transmission member to cooperate with the gear and bevel gear system, and through the movement thereof, the synchronous action of the cover plate and the clamping member 111 is realized. The first gear 12 is arranged at the end of the clamping member 111 and meshes with the tooth portions on the two sides of the transmission member. This means that when the transmission member moves, the first gear 12 rotates, thereby driving the clamping member 111 to swing, and realizing the clamping or swinging out of the clamping member 111 from the clamping groove 110 of the filter plate 109. The second gear 13 is rotatably arranged on the partition plate 117 and meshes with the tooth portion on the upper side of the transmission member. The rotation of the second gear 13 is driven by the movement of the transmission member, and the function thereof is to transmit the movement to the bevel gear system through gear transmission, and further control the swinging of the cover plate. The first bevel gear 14 is coaxially arranged with the second gear 13, and the second bevel gear 15 is arranged at the end of the cover plate. When the second gear 13 rotates, through the cooperation of the first bevel gear 14 and the second bevel gear 15, the rotary movement can be converted into the swinging of the cover plate, and the opening or closing of the through hole 108 of the partition plate 117 by the cover plate is realized. In summary, through the precise combination of the transmission member, the gear and the bevel gear, the synchronous swinging of the cover plate and the clamping member 111 is realized, which not only improves the degree of automation of the equipment, but also optimizes the replacement and fixing process of the filter plate 109. Through the synchronous action of the cover plate and the clamping member 111, when the clamping member 111 is not moved to the position during the replacement of the filter plate 109, the clamping member 111 can be swung to be opened synchronously when the filter plate 109 is moved out of the lower cavity 104 by the replacement clamp 112, so as to avoid the interference between the new filter plate 109 and the clamping member 111 when the new filter plate 109 enters the lower cavity 104, thereby reducing the failure rate of the equipment and reducing the labor intensity of the operating personnel.

[0081] In this embodiment, the linear drive 16 is arranged on the cover plate for precise control of the movement of the transmission member. Through the driving of the linear drive 16, the transmission member can move according to the predetermined trajectory, and then through the gear and bevel gear system, the synchronous swing of the cover plate and the clamping member 111 is realized, and the opening and closing of the through hole 108 is controlled. The first rotating drive 17 is arranged outside the casing 101 for driving the rotation of the first lead screw 2. This design enables the moving member 3 to move linearly along the axis direction of the first lead screw 2, realizing the positioning of the replacement clamp 112 in the horizontal direction. The second rotating drive 18 is arranged on the moving member 3 for driving the rotation of the second lead screw 5. The rotation of the second lead screw 5 controls the vertical movement of the lifting member 6, and then realizes the lifting of the replacement clamp 112, facilitating the replacement and taking out of the filter plate 109. The third rotating drive 19 is also arranged outside the casing 101 for driving the rotation of the third lead screw 9. The rotation of the third lead screw 9 controls the movement of the blocking member 10, thereby realizing the automatic adjustment of the filter plate 109 from the vertical to the horizontal position, simplifying the process of replacing the filter plate 109. In summary, through the design of the linear drive 16 and multiple rotating drives, the automatic control of the key components of the equipment is realized, not only improving the efficiency of replacing and maintaining the filter plate 109, but also optimizing the running stability and operation safety of the equipment, avoiding the damage to the equipment caused by the low operation precision of the operator, and reducing the failure rate of the equipment.

[0082] Further, the end of the replacement clamp 112 has a plurality of cylindrical electromagnets 113, and the end of the filter plate 109 has a metal cavity hole 114 for accommodating the cylindrical electromagnets 113.

[0083] In this embodiment, the end of the replacement clamp 112 is designed with several cylindrical electromagnets 113. These electromagnets generate magnetic force in the energized state, which is used to attract and fix the filter plate 109. The end of the filter plate 109 is provided with a metal cavity hole 114, which is matched in size with the cylindrical electromagnet 113 and can accommodate the cylindrical electromagnet 113. The material of the metal cavity hole 114 is usually magnetically conductive metal, such as iron, steel, etc., so that it can be effectively attracted when the cylindrical electromagnet 113 generates a magnetic field. When the replacement clamp 112 moves to the position of the filter plate 109, the cylindrical electromagnet 113 is inserted into the metal cavity hole 114, and through the magnetic force generated by the electromagnet, the filter plate 109 can be quickly adsorbed and fixed on the replacement clamp 112, realizing the rapid positioning and stable fixation of the filter plate 109, which is convenient for the replacement and maintenance of the filter plate 109. The cooperation design of the cylindrical electromagnet 113 and the metal cavity hole 114 not only improves the efficiency of the replacement of the filter plate 109, but also ensures the safety of the replacement process. The magnetic force of the electromagnet can be turned on or off according to the needs, avoiding the complexity and safety hazards that may be caused by the traditional mechanical fixing method. In summary, through the innovative design of the cylindrical electromagnet 113 and the metal cavity hole 114, the rapid positioning and stable fixation of the filter plate 109 during the replacement process are realized, which not only simplifies the operation steps, but also improves the automation level and operation safety of the equipment.

[0084] Further, the upper cavity 103 has an inlet 115 for the filter plate 109 to enter the upper cavity 103 and an outlet 116 for the filter plate 109 to move out of the upper cavity 103, and further comprises a material leakage hole 20 arranged below the casing 101 and communicating with the lower cavity 104, and a main fan 21 communicating with the clean air outlet 106.

[0085] In this embodiment, the upper cavity 103 is designed with an inlet 115 and an outlet 116. The inlet 115 is used for the filter plate 109 to enter the upper cavity 103, facilitating the installation and positioning of the filter plate 109. The outlet 116 is used for the filter plate 109 to move out of the upper cavity 103, facilitating the replacement and cleaning of the filter plate 109. This design ensures smooth and convenient replacement of the filter plate 109. The inlet 115 and the outlet 116 are at the same level. After the replacement clamp 112 removes the filter plate 109 from the upper cavity 103, the lifting member 6, the moving member 3, and the blocking member 10 cooperate to rotate 180 degrees, and then a new filter plate 109 is moved into the upper cavity 103 through the inlet 115. After that, the moving member 3 and the lifting member 6 cooperate to move the new filter plate 109 into the lower cavity 104. The material leakage port 20 is arranged below the casing 101 and communicates with the lower cavity 104, mainly used for collecting dust or particulate matter collected during the filtering process of the filter plate 109. Considering that the material leakage port 20 is designed to communicate with the lower cavity 104, the dust collector 1 cannot achieve dust collection. The upper part of the material leakage port 20 is designed with a baffle, and the filter plate 109 is designed as a back-shaped filter plate 109. The collected material can be made to fall in the middle of the back-shaped filter plate 109 by setting a pulse jet port between the two filter plates 109, avoiding accumulation affecting the performance of the equipment, and also facilitating the collection and utilization of the material. The main fan 21 communicates with the clean gas outlet 106, used for sucking and purifying the air filtered by the filter plate 109. The operation of the main fan 21 can maintain the negative pressure state inside the equipment, promote the circulation of air and material, and at the same time discharge the purified air to the external environment, reducing the pollution to the environment. In summary, through the integrated design of the inlet and outlet 116 of the upper cavity 103, the material leakage port 20, and the main fan 21, the material processing and air purification process are optimized, which not only improves the operating efficiency and environmental performance of the equipment, but also simplifies the replacement and maintenance process of the filter plate 109, reflecting the comprehensiveness and practicality of the design.

[0086] Further, it further comprises a hot blast stove 22, a primary grinding 23 located on one side of the dust collector 1, the primary grinding 23 having a grinding cavity, the hot blast stove 22 leading to the grinding cavity, the grinding cavity leading to the dust collector 1, the distribution pipe 24 having a first communication port 2401, a second communication port 2402 and a third communication port 2403, the first communication port 2401 communicating with the material leakage port 20, the secondary grinding 25 having a fine grinding cavity, the fine grinding cavity communicating with the second communication port 2402, the fine grinding cavity leading to the first elevator 26, the third communication port 2403 leading to the first elevator 26, the material bin 27 being a plurality of bins for storing different materials, the first elevator 26 leading to the material bin 27, the material bin 27 leading to the conveying member 28, the conveying member 28 leading to the material mixer 29, the material mixer 29 leading to the second elevator 30, the second elevator 30 leading to the finished product warehouse 31.

[0087] In this embodiment, the hot air provided by the hot air furnace 22 enters the grinding chamber of the primary grinding mill 23, which is used to dry and preheat the ground material, thereby improving the grinding efficiency. The material processed by the primary grinding mill 23 is directly sent to the dust collector 1 for preliminary dust collection. The distribution pipe 24 is connected to the material leakage port 20 below the dust collector 1 through its first communication port 2401, and the collected material is distributed to the secondary grinding mill 25 and the first elevator 26 through the distribution pipe 24. This design ensures the reasonable distribution and efficient use of the material. The fine grinding chamber of the secondary grinding mill 25 receives the material from the distribution pipe 24, which is finely ground to improve the quality and uniformity of the finished product. The ground material is sent to the silo 27 by the first elevator 26, which is used to store different types of materials for subsequent batching and mixing. The material in the silo 27 is sent to the mixer 29 by the conveying element 28 for accurate material batching and mixing to ensure the quality and performance of the finished product. The mixed material is sent to the finished product warehouse 31 by the second elevator 30, which is used to store the final product for packaging and shipping. In summary, through the integrated design of the hot air furnace 22, the primary grinding mill 23, the secondary grinding mill 25, the distribution pipe 24, the first elevator 26, the silo 27, the conveying element 28, the mixer 29, the second elevator 30, and the finished product warehouse 31, a complete production line from raw material processing to finished product preparation is constructed, which improves the production efficiency and product quality.

[0088] The low-carbon integral cementitious material production process based on particle grading technology uses a low-carbon integral cementitious material grinding device based on particle grading technology, which includes the following steps:

[0089] S1: After the material is quantitatively batched, it is subjected to primary grinding treatment,

[0090] S2: The hot air blower blows hot air into the primary grinding mill 23, and the hot air blows the powder with a specific surface area of 550㎡ / Kg into the dust collector 1, and the dust collector 1 discharges the powder into the material leakage port 20,

[0091] S3: The material leakage port 20 sends the powder into the distribution pipe 24, and the distribution pipe 24 uses a distribution valve to send 30%-50% of the powder into the secondary grinding mill 25, and the remaining powder into the first elevator 26,

[0092] S4: The secondary grinding mill 25 grinds the powder to a specific surface area of up to 700㎡ / Kg, D50≦6.5㎛, and the content of particles below 3㎛ is 30%,

[0093] S5: The powder after the secondary grinding mill 25 is mixed with the powder produced by the primary grinding mill 23 on the first elevator 26, and the mixed material is discharged into a silo 27,

[0094] S6: The several bins 27 send the material into the conveying member 28, the conveying member 28 sends the material into the mixer 29, the mixer 29 sends the mixed material into the second elevator 30, and the second elevator 30 sends the mixed material into the finished product warehouse 31.

[0095] In this embodiment, first, according to the performance index of the required product, the raw materials are accurately proportioned, and then the proportioned materials are sent into the primary grinding 23 for preliminary grinding. The hot air blower blows hot air into the primary grinding 23, and the hot air not only dries the material, but also carries the powder with a specific surface area of 550㎡ / Kg into the dust collector 1. The dust collector 1 preliminarily collects the powder, and then discharges the powder into the leakage port 20. The leakage port 20 sends the collected powder into the distribution pipe 24, and the distribution pipe 24 sends 30%-50% of the powder into the secondary grinding 25 through the distribution valve, and the remaining powder directly enters the first elevator 26, ready to be mixed with other materials. The secondary grinding 25 further grinds the received powder to make its specific surface area reach 700㎡ / Kg, the particle size D50≦6.5㎛, and the content of particles below 3㎛ is 30%, realizing finer particle grading and improving the performance of the finished product. The powder after secondary grinding is mixed with the powder produced by the primary grinding on the first elevator 26 to ensure the uniformity of the finished product. The mixed material is discharged into a bin 27 for temporary storage. The several bins 27 send the material into the conveying member 28, the conveying member 28 sends the material into the mixer 29 for final mixing to ensure that all ingredients are evenly distributed. The mixer 29 sends the mixed material into the second elevator 30, and the second elevator 30 sends the material into the finished product warehouse 31, completing the production process. The secondary stage grinding can realize any proportion mixing and matching with the primary grinding product. The specific surface area of the product after secondary grinding can reach 700㎡ / Kg, D50≦6.5㎛, and the content of particles below 3㎛ can reach 30%. The specific surface area of the primary grinding product is S=550㎡ / Kg, D50≦8.0㎛, and the content of particles below 3㎛ is about 20%. This can make the particle size distribution of the stage grinding product wider, achieving better overall cementitious material filling effect. The product particle after secondary grinding processing has better circularity, better product flowability and filling property; the produced solid waste-based cementitious material has better performance, and has excellent cementitious and filling properties. The solid waste-based cementitious material produced by this process replaces 20%-40% of cement in the preparation of overall cementitious material. Since the carbon emission of solid waste-based cementitious material is only about 10% of that of cement, the carbon emission of the produced overall cementitious material can be reduced by 15%-35%. In summary, this production process makes full use of the low-carbon overall cementitious material grinding equipment based on particle grading technology, realizes efficient production of low-carbon cementitious material through accurate material proportioning, hot air drying, two-stage grinding, and fine mixing, and ensures the high quality and environmental protection of the finished product.

[0096] Further, the material proportioning in step S1 is completed by a plurality of quantitative scales 32 weighing a plurality of materials in sequence and then feeding the materials into the primary grinding 23.

[0097] In this embodiment, different types of raw materials are accurately weighed by respective quantitative scales 32. The weight of each raw material is pre-set according to the formula requirements, and the quantitative scales 32 can ensure the accuracy of each weighing, which is the basis for realizing the quality control of finished products. After weighing, each raw material is sequentially fed into the primary grinding 23. This sequence is usually determined according to the properties of the raw materials and the grinding efficiency to ensure that the raw materials can be optimally processed during the grinding process. Although the raw materials have been weighed according to the proportion before the primary grinding 23, the raw materials will be further mixed during the grinding process to ensure uniform distribution of various components in the finished product, which is the key to realizing stable product performance. By using multiple quantitative scales 32 to weigh different materials in sequence and feed the materials into the primary grinding 23, not only the accuracy of the material proportioning is improved, but also the continuity and efficiency of the production process are ensured, which is a necessary step to realize high-quality and high-efficiency production. This method effectively controls the raw material proportioning of each batch of products, thereby ensuring the performance and consistency of the final product, meeting the requirements of modern industrial production for precise control.
