Description

Technical Field

[0001] This invention relates to the field of ceramic waste treatment technology, and in particular to a ceramic waste sintering tile production equipment. Background Technology

[0002] Sintered tiles are roofing materials made from clay or other inorganic non-metallic raw materials such as shale and coal gangue through molding and sintering. The production process includes raw material crushing, mixing, extrusion molding, and drying.

[0003] Ceramic waste can replace 10-40% of clay in the production of sintered tiles. It needs to be crushed and screened to remove impurities. Some waste is activated by calcination to enhance its activity. The moisture content needs to be controlled at 18-22% during the mixing stage. Water is added quantitatively during stirring, and then the tiles are extruded or pressed into shape. The final fired tiles have both frost resistance, weather resistance and decorative effect.

[0004] However, traditional technology has some problems: during the raw material mixing stage of sintered tile production, the uneven distribution of moisture due to the difference in water absorption of the raw materials can cause uneven hardness of the green body during molding, making it easy to break or wrinkle on the surface during extrusion; and it can also cause cracks to expand at high temperatures during the sintering stage, leading to warping, bulging or even breakage of the tile body. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of uneven moisture content in raw materials leading to cracking during green body forming, microcracks during drying, deformation during sintering, and decreased strength and frost resistance of finished products in the prior art. Therefore, this invention proposes a ceramic waste sintering tile production equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ceramic waste sintered tile production device includes a base, and further includes: a central tube fixed to the upper part of the base, the upper part of the base having several recesses, a first feeding channel between the central tube and the base, the central tube being connected and communicating with the base through the first feeding channel; a transmission pipe fixed to the outside of the central tube, with corresponding recesses, the upper part of the central tube having a second feeding channel, the upper part of the transmission pipe communicating with the second feeding channel; and a mixing component including an auger rotatably mounted on the upper part of the base and located in the middle of the transmission pipe, wherein, when adding water to the raw materials, the auger is rotated, and the raw materials are transported from the recesses of the base through the transmission pipe to the upper layer of the central tube for uniform water addition and mixing.

[0008] Preferably, a housing is fixedly connected to the upper part of the base, and the housing is located outside the central tube and the transmission tube.

[0009] To enable water to be added to the raw materials in the central tube, preferably, a cover is inserted and installed on the upper part of the machine casing, a connecting seat for connecting a water pump is fixedly installed on the upper part of the cover, and several atomizing nozzles are fixedly installed on the lower part of the cover, with the atomizing nozzles communicating with the connecting seat.

[0010] To achieve uniform water addition, the atomizing nozzle receives the liquid transmitted by the connector and sprays it evenly onto the raw material on the upper layer of the central tube.

[0011] To drive the gear ring, a first gear is fixedly installed at the motor output end, which is fixedly mounted outside the housing, and the gear ring, which is rotatably mounted on the upper part of the housing, meshes with the first gear.

[0012] To enable the motor to drive multiple augers, the augers are further provided, and each auger has a second gear fixedly connected to its upper part. The second gear meshes with the inner side of the gear ring, and the multiple augers are driven by the motor to perform rotational transmission.

[0013] To facilitate the feeding of mixed raw materials, a lifting column is further screwed to the center of the base, and the feeding action is performed when the lifting column is withdrawn.

[0014] Compared with the prior art, the present invention provides a ceramic waste sintering tile production equipment, which has the following beneficial effects:

[0015] This ceramic waste sintering tile production equipment effectively solves the problem of uneven water absorption between ceramic waste and clay through a vertical circulation mixing and gradient wetting mechanism. After startup, the raw material enters the feeding channel from the base depression and is lifted to the top of the central pipe by the auger along the transmission pipe. The spiral shearing force of the auger blades breaks up the agglomerates, and the serrated edges cut off the adsorbed clumps. After the material reaches the top, it falls into the atomization zone through the feeding channel. The high-pressure atomizing nozzle converts water into micron-sized droplets, forming a uniform water curtain for initial wetting. The highly absorbent clay preferentially absorbs water, while the ceramic waste... Micro-cracks are generated by the friction of the auger, which increases the water absorption rate. The material that is not fully penetrated falls back to the base. After multiple cycles, deep penetration is achieved. The infrared moisture meter monitors the moisture content in real time. The water pump flow rate is adjusted by the algorithm to avoid over-wetting or dryness. Finally, the moisture distribution of the material is uniform after circulation, the extrusion molding qualification rate is significantly improved, the flexural strength of the tile body is stable after sintering, and the auger power is automatically cut off when the lifting column is feeding material, reducing energy consumption. This design overcomes the technical bottleneck of uneven water absorption of heterogeneous raw materials through the synergistic effect of spatial layered wetting and forced time cycle.

[0016] The parts not covered in this device are the same as or can be implemented using existing technologies. This invention achieves uniform moisture distribution of raw materials through cyclic mixing and atomized wetting, improves the molding qualification rate and tile strength, reduces energy consumption, and effectively solves the problem of uneven water absorption of ceramic waste and clay.

[0028] Example:

[0029] Reference Figures 1-6 A ceramic waste sintering tile production equipment includes a base 1, and further includes: a central pipe 9, which is fixed to the upper part of the base 1. The upper part of the base 1 has several recesses 10. A first feeding channel 7 is provided between the central pipe 9 and the base 1, and the central pipe 9 is connected to the base 1 through the first feeding channel 7; a transmission pipe 12, which is fixed to the outside of the central pipe 9 and correspondingly provided with the recesses 10. A second feeding channel 8 is provided on the upper part of the central pipe 9, and the upper part of the transmission pipe 12 is connected to the second feeding channel 8; and a mixing component 6, which includes an auger 605. The auger 605 is rotatably installed on the upper part of the base 1 and located in the middle of the transmission pipe 12. When adding water to the raw materials, the auger 605 is rotated, and the raw materials are transmitted from the recesses 10 of the base 1 through the transmission pipe 12 to the upper layer of the central pipe 9 for uniform water addition and mixing.

[0030] The aforementioned ceramic waste sintered tile production equipment addresses the problem of uneven moisture distribution caused by differences in the water absorption of raw materials through a vertical circulation mixing and gradient wetting mechanism.

[0031] Specifically, it is divided into three stages: material lifting and dispersion, stratified atomization and penetration, and dynamic circulation homogenization;

[0032] After the equipment starts, ceramic waste and clay materials at the bottom of the base 1 enter the first feeding channel 7 through the depression 10. The auger 605, rotating at 30 to 50 revolutions per minute, vertically lifts the materials along the transmission pipe 12 to the top of the central pipe 9, at a height of 1.2 to 1.5 meters. During this process, the spiral shearing force of the auger 605 blades breaks up the agglomerated materials into fine powder of less than or equal to 0.5 mm, accounting for over 85%. Simultaneously, the serrated edges, with a tooth depth of 2 to 3 mm, cut off the adsorbed clumps of clay and waste. After reaching the top, the material naturally falls through the second feeding channel 8 to the upper atomization zone of the central pipe 9. The high-pressure atomizing nozzle 5 on the cover 3, with an orifice diameter of 0.1 mm, converts water into 50 to 100 micrometer-sized droplets, forming a uniform water curtain covering more than 80% of the pipe diameter, achieving initial wetting. At this point, the highly absorbent clay particles, with a specific surface area of ​​20 to 30 square meters per gram, preferentially absorb 70% of the water, while the vitrified ceramic waste, due to the auger 605... 05 Friction generates micro-cracks, increasing the water absorption rate from 5% to 15%. The incompletely permeated material falls back to the bottom of base 1 under gravity and is lifted and circulated again by auger 605. After 2 to 3 cycles, the waste material achieves deep water penetration through mechanical friction and repeated wetting. The infrared moisture meter monitors the moisture content of base 1 in real time, and the water pump flow rate is dynamically adjusted through a PID algorithm with an accuracy of ±0.5%, avoiding local over-wetting greater than 23% or dryness less than 18%. Finally, after 4 to 5 cycles, the standard deviation of moisture distribution of the material decreases from ±2.5% to ±0.7%, the extrusion molding qualification rate increases to 95%, and the flexural strength of the tile body stabilizes at 18 to 20 MPa after sintering. Moreover, the lifting column 11 automatically cuts off the power of auger 605 when discharging material, reducing energy consumption by 18%. This design overcomes the technical bottleneck of uneven water absorption of heterogeneous raw materials through the synergistic effect of spatial layered wetting and forced time circulation.

[0033] Preferably, a housing 2 is fixedly connected to the upper part of the base 1, and the housing 2 is located outside the central tube 9 and the transmission tube 12. To add water to the raw material in the central tube 9, preferably, a cover 3 is inserted and installed on the upper part of the housing 2. A connecting seat 4 for connecting a water pump is fixedly installed on the upper part of the cover 3, and several atomizing nozzles 5 are fixedly installed on the lower part of the cover 3, communicating with the connecting seat 4. To achieve uniform water addition, the atomizing nozzles 5 receive the liquid transmitted from the connecting seat 4 and perform a uniform spraying operation on the raw material on the upper layer of the central tube 9.

[0034] The housing 2 serves as the core protective structure, covering the central tube 9 and the transmission tube 12 to prevent dust from spilling out and maintain equipment stability. The cover 3 is fixed to the top of the housing 2 by a plug-in connection, and the connecting seat 4 installed on it is connected to the water pump to provide a stable water source for the atomizing nozzle 5. The atomizing nozzle 5 converts water into 50 to 100 micrometer-sized droplets with an aperture of 0.1 mm, forming a uniform water curtain that covers the material on the upper layer of the central tube 9.

[0035] When the auger 605 lifts the raw material to the top of the central tube 9, the material falls through the water mist zone, achieving stratified wetting. The highly absorbent clay preferentially absorbs water, while the ceramic waste gradually penetrates through multiple cycles of lifting, ensuring uniform moisture distribution.

[0036] To drive the gear ring 603, a first gear 602 is fixedly mounted on the output end of the motor 601, which is fixedly installed outside the housing 2. The gear ring 603, rotatably mounted on the upper part of the housing 2, meshes with the first gear 602. To enable the motor 601 to drive multiple augers 605, multiple augers 605 are provided. Each auger 605 has a second gear 604 fixedly connected to its upper part. The second gear 604 meshes with the inner side of the gear ring 603, and the multiple augers 605 rotate under the drive of the motor 601.

[0037] The motor 601 transmits power to the gear ring 603 through the first gear 602 at the output end. When the gear ring 603 rotates, its inner side meshes with the second gear 604 on the upper part of multiple augers 605, driving the augers 605 to rotate synchronously.

[0038] The speed of motor 601 is controlled at 30 to 50 revolutions per minute by frequency converter to ensure the efficiency of shearing and lifting of raw materials by auger 605 blades.

[0039] Multiple augers 605 work together at the same speed to avoid local accumulation of materials or uneven transmission. At the same time, the precise transmission through gear meshing reduces power loss and improves the stability of equipment operation.

[0040] To facilitate the feeding of mixed raw materials, a lifting column 11 is further screwed to the center of the base 1. The lifting column 11 performs the feeding action when it is pulled out.

[0041] The base 1 has a screw-type lifting column 11 at its center, which is controlled by hydraulic or mechanical drive. After mixing is completed, the lifting column 11 is slowly pulled away, and the material at the bottom is discharged naturally under the action of gravity. The lifting speed of the lifting column 11 can be adjusted to ensure that the material is discharged evenly and without residue.

[0042] In this invention, the raw material enters the first feeding channel 7 from the recess 10 of the base 1. It is then lifted by the auger 605 at 30 to 50 revolutions per minute along the transmission pipe 12 to the top of the central pipe 9, at a height of 1.2 to 1.5 meters. The spiral shearing force of the auger 605 blades breaks up the agglomerates into fine powder of less than or equal to 0.5 mm with a proportion of more than 85%. The serrated edge cuts off the adsorbed clumps. After the material reaches the top, it is scattered into the atomization zone through the second feeding channel 8. The high-pressure atomizing nozzle 5 converts water into 50 to 100 micrometer-sized droplets, forming a water curtain covering more than 80% of the pipe diameter, achieving initial wetting. The highly absorbent clay preferentially absorbs 70% of the water. The ceramic waste is rubbed by the auger 605 to generate microcracks, increasing the water absorption rate from 5% to 15%. The material that has not fully penetrated falls back to the base 1. After 2 to 3 cycles, deep penetration is achieved. The infrared moisture meter monitors the moisture content in real time, and the water pump flow rate is adjusted by the PID algorithm with an accuracy of ±0.5%, avoiding over-wetting or dryness.

[0043] Ultimately, after 4 to 5 cycles, the standard deviation of moisture distribution in the material decreased from ±2.5% to ±0.7%, the extrusion molding qualification rate increased to 95%, and the flexural strength of the tile body stabilized at 18 to 20 MPa after sintering. Furthermore, the lifting column 11 automatically cut off the power of the auger 605 when feeding material, reducing energy consumption by 18%. This design overcomes the technical bottleneck of uneven water absorption of heterogeneous raw materials through the synergistic effect of spatial layered wetting and forced time cycle.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
