Description

Technical Field

[0001] The invention relates to the technical field of concrete feeding, in particular to a solid waste cementitious material concrete feeding device. Background Art

[0002] The solid waste cementitious material concrete feeding device is an automated equipment specially designed for processing solid waste such as construction waste and industrial waste and mixing them with cementitious materials to prepare concrete.

[0003] In the context of resource utilization of construction waste and comprehensive treatment of industrial solid waste, traditional solid waste cementitious concrete feeding equipment has exposed multiple technical bottlenecks, directly restricting the production efficiency and quality stability of recycled aggregate concrete. Existing equipment generally suffers from two core flaws: First, the dust suppression system often uses a post-mounted bag filter, which is unable to suppress dust generation during the initial material transportation stage, resulting in excessive dust concentration in the working environment, which not only endangers the health of operators but also causes the loss of effective components of the cementitious material. Second, during the feeding process, the material dispersion system often relies on a single-stage vibration or fixed feed mechanism. When dealing with the brick-concrete mixture commonly found in construction waste, it is difficult to effectively break up the agglomerated material and evenly distribute the material, which directly affects the working performance of the concrete.

Two symmetrically arranged rotating gears are fixedly sleeved on the stirring rod, and the two rotating gears are meshed with each other.

[0011] As a preferred solution of the present invention, a long shaft is rotatably installed inside the main body, a transmission gear is fixedly sleeved on the outer circumference of the long shaft, the transmission gear is engaged with one of the rotating gears, an inner gear ring is rotatably installed inside the main body, a plurality of equally spaced connecting rods are fixedly connected to the top of the inner gear ring, and a plurality of equally spaced spoiler blades are fixedly connected to one side of the connecting rod.

[0014] 2. The present invention constructs a multi-dimensional mixing system by setting up structures such as a distribution component and a stirring component. Four sets of parallel rotating shafts form a planetary transmission system through meshing gears. The adjacent shafts rotate in opposite directions to generate a shear force field. The large-pitch distribution plate at the front end is used to break up the agglomerated materials. The closely spaced distribution plates at the rear end realize gradient distribution. The rotating shaft driven by the dual transmission shafts forms a revolution-rotation compound motion through a bevel gear set. The stirring blades and the spoiler blades work together to generate a three-dimensional turbulent field, which is especially effective for high-viscosity solid waste gelling materials, achieving improved uniformity and eliminating the material segregation phenomenon of traditional devices.

[0019] Furthermore, a solid waste cementitious material concrete feeding device has a main body 10 frame made of high-strength alloy steel structure, and the top is movably connected to the feeding assembly 1 through a hinged shaft. The feeding assembly 1 is composed of a feeding plate 11 with an adjustable inclination angle, and its surface is covered with a wear-resistant coating to adapt to the friction of solid waste materials. A dust reduction assembly 2 is fixedly installed on the top of the main body 10, and its dust reduction baffle 21 is an arc-shaped surrounding structure. A double straight shaft 24 air inlet system is arranged inside, and the gear set is driven by the servo motor 23 to achieve synchronous rotation. The surface of the air inlet block 242 is densely covered with atomizing nozzles, and the negative pressure adsorption principle is used to suppress dust diffusion. The uniform distribution assembly 3 is located below the dust reduction assembly 2, and is composed of four groups of parallel rotating shafts 311. A spiral uniform distribution plate 312 is welded on the surface of each shaft body, and adjacent shaft bodies are rotated in opposite directions through meshing gears 313, forming a multi-stage dispersion effect on the material. The mixing assembly 4 utilizes a dual drive shaft 41 linked to a rotating shaft 42. The drive shaft 41 drives the rotating shaft 42 in orbital motion via a bevel gear set. Simultaneously, the gear at the end of the rotating shaft 42 meshes with the internal gear ring 44, driving a set of spoiler blades 442 to generate a three-dimensional mixing flow field. The discharging assembly 5, driven by a discharging motor 51, rotates the discharging plate 511, which cooperates with guide plates to achieve directional discharge. Each component utilizes a mechanical transmission chain to achieve a continuous process of feeding, dust reduction, uniform distribution, stirring, and discharging. This is particularly suitable for uniformly mixing recycled aggregates from construction waste with cementitious materials.

[0020] In this embodiment, the feeding assembly 1 is composed of a feeding plate 11, which is movably hinged on the top of the main body 10.

The transmission motor 12 is fixed to the side wall of the main body 10 by bolts, and its output shaft is sleeved with a high-strength polyurethane transmission belt 121, and the other end of the transmission belt 121 is connected to the main shaft of the feeding plate 11. When the motor is started, the transmission belt 121 drives the feeding plate 11 to rotate around the hinge axis through friction transmission, realizing 0-45° inclination adjustment. Anti-slip grooves are provided on the surface of the feeding plate 11, which cooperates with the vibration motor to realize efficient transportation of solid waste materials. The component controls the feeding speed by adjusting the motor speed, and realizes automatic angle positioning in conjunction with the limit sensor on the top of the main body 10. It is particularly suitable for the stable feeding requirements of solid waste cementitious materials with large differences in water content.

[0023] Furthermore, the lifting cylinder 13 is fixed to the side wall of the main body 10 through a flange, and a double-ear lifting shaft 131 is provided at the end of its piston rod. The hinged rod 132 welded to the bottom of the feed plate 11 adopts a ball joint structure to form a universal connection with the lifting shaft 131. When the cylinder is extended and retracted, the feed plate 11 is driven to rotate around the hinge axis through the lever principle to achieve stepless angle adjustment. The cylinder has a built-in magnetostrictive displacement sensor, which feeds back the position signal of the feed plate 11 to the control system in real time to form a closed-loop control. The mechanism adopts a nitrogen spring auxiliary support design to effectively reduce the cylinder load fluctuation, and is particularly suitable for the dynamic angle adjustment scenario during the transportation of large-block solid waste materials.

[0024] In this embodiment, the dust reduction assembly 2 is composed of a dust reduction baffle 21, which is fixedly connected to the top of the main body 10. A servo motor 23 is installed on one side of the dust reduction baffle 21, and a driving gear 231 is installed on the output end of the servo motor 23.

A transmission belt 232 is jointly sleeved on the other straight shaft 24 and the output shaft of the servo motor 23. One end of the straight shaft 24 is fixedly connected to an air inlet block 242, and one side of the air inlet block 242 is installed with several equidistantly distributed air outlets 243. One side of the dust reduction baffle 21 is fixedly connected to a dust outlet 22.

[0025] Furthermore, the dust reduction baffle 21 adopts a double-layer hollow structure, and a spiral guide groove is provided on the inner wall. The servo motor 23 drives the driving gear 231 through the reducer, forming a 90° right-angle transmission with the driven gear. Another set of straight shafts 24 is connected to the motor shaft through a synchronous belt to achieve dual-axis out-of-phase rotation. The air inlet block 242 integrates a high-pressure fan and an atomizing nozzle, which generates a centrifugal airflow field during rotation, and cooperates with the angle adjustment mechanism of the air outlet 243 to form a three-dimensional dust reduction area. The dust outlet 22 adopts a Venturi tube structure, which uses negative pressure suction to guide dust into the bag dust collector. This component adjusts the fan speed through the frequency converter to adapt to the dust reduction needs of solid waste materials of different particle sizes, effectively solving the dust pollution problem in concrete production.

[0026] In this embodiment, the equalizing assembly 3 comprises a rotating motor 31, which is mounted on one side of the main body 10. Four equally spaced rotating shafts 311 are rotatably mounted within the main body 10. One of the rotating shafts 311 is connected to the output end of the rotating motor 31 via a coupling. A plurality of equally spaced equalizing plates 312 are fixedly connected to the rotating shaft 311. A meshing gear 313 is fixedly sleeved on the rotating shaft 311, and two adjacent meshing gears 313 mesh with each other.

[0027] Furthermore, the evenly distributed component 3 is composed of four sets of rotating shafts 311, with trapezoidal evenly distributed plates 312 welded on the surface of the shaft body, and adjacent shafts achieve opposite synchronous rotation through meshing gears 313. The rotating motor 31 drives the main shaft through an elastic pin coupling, and the main shaft gear drives the driven shaft gear set to form a planetary transmission structure. The evenly distributed plate 312 adopts a variable pitch design, with a larger helix angle at the front end to break up agglomerated materials, and a smaller pitch at the rear end to achieve uniform distribution. This component is continuously lubricated through the lubricating oil circuit in the gearbox, and cooperates with the shaft end encoder to detect the synchronization of the speed. It is particularly suitable for the dispersion and processing of solid waste cementitious materials containing fiber-reinforced materials.

[0028] In this embodiment, the stirring assembly 4 is composed of two transmission shafts 41, and the two transmission shafts 41 are symmetrically arranged and rotatably installed inside the main body 10. A linkage belt 314 is jointly provided on the transmission shaft 41 and two of the rotating shafts 311. One end of the transmission shaft 41 is fixedly connected to an active bevel gear 411. Two symmetrically arranged rotating shafts 42 are rotatably installed inside the main body 10, and one end of the rotating shaft 42 is fixedly connected to a follower bevel gear 420. The active bevel gear 411 and the follower bevel gear 420 are meshed with each other. A stirring rod 422 is fixedly connected to the top of the rotating shaft 42, and a plurality of equally spaced stirring blades 423 are fixedly sleeved on the outer peripheral surface of the stirring rod 422. Two symmetrically arranged rotating gears 421 are fixedly sleeved on the stirring rod 422, and the two rotating gears 421 are meshed with each other.

[0029] Furthermore, the stirring component 4 adopts a cross transmission structure of dual transmission shafts 41 and dual rotating shafts 42. The transmission shaft 41 drives the rotating shaft 42 to revolve through the linkage belt 314, and the active bevel gear 411 at the end of the rotating shaft 42 is meshed with the driven bevel gear to form a planetary gear train. Double helical stirring blades 423 are welded on the surface of the stirring rod 422, and a detachable scraper is provided between adjacent stirring blades 423. The rotating gear 421 group drives the inner ring gear 44 to rotate, driving the turbulent blade 442 group to generate a radial stirring flow field. This component forms a complex turbulent flow field in the stirring barrel through the differential transmission design, which is particularly suitable for the uniform mixing of high-viscosity solid waste gelling materials, and effectively avoids the floating separation phenomenon of lightweight materials.

[0030] In this embodiment, a long shaft 43 is rotatably installed inside the main body 10, and a transmission gear 431 is fixedly sleeved on the outer circumference of the long shaft 43.

An inner ring gear 44 is rotatably installed inside the main body 10, and a plurality of equally spaced connecting rods 441 are fixedly connected to the top of the inner ring gear 44, and a plurality of equally spaced spoiler blades 442 are fixedly connected to one side of the connecting rod 441.

[0031] Furthermore, the long shaft 43 is mounted to the bottom of the main body 10 via a spherical roller bearing, with a transmission gear 431 at its end meshing with the rotating gear 421. The inner ring gear 44 is axially positioned via a thrust ball bearing, and streamlined spoiler blades 442 are welded to the surface of the connecting rod 441. When the rotating gear 421 drives the inner ring gear 44 to rotate, the spoiler blades 442 generate an axial circulating flow field, which forms a three-dimensional mixing effect with the radial flow field of the stirring blades 423. This mechanism, through a gear module matching design, achieves an adjustable speed ratio between revolution and rotation, making it particularly suitable for the rapid homogenization of solid waste concrete with the addition of chemical admixtures.

[0032] In this embodiment, the discharging assembly 5 is composed of a discharging motor 51, which is installed at the bottom of the main body 10. A discharging plate 511 is installed at the output end of the discharging motor 51, and a discharging guide plate 52 is fixedly connected to the bottom of the main body 10.

[0033] Furthermore, the discharge assembly 5 is driven by a discharge motor 51, which drives an eccentric discharge plate 511. The plate surface is coated with a wear-resistant ceramic coating. The discharge guide plate 52 features an adjustable inclination angle, adjustable from 0 to 30° via a hydraulic lever. When the motor drives the discharge plate 511 to rotate, the material is discharged along the guide plate under the influence of centrifugal force. A vibrator is installed inside the guide plate to prevent wet and sticky materials from sticking. This assembly uses a torque sensor to monitor discharge resistance in real time, and combined with variable frequency speed regulation, achieves closed-loop flow control, making it particularly suitable for the precise discharge requirements of solid waste concrete of varying consistencies.

[0034] A solid waste cementitious material concrete feeding device adopts a modular integrated design. The main body 10 frame is constructed of high-strength alloy steel and is equipped with a continuous operation system for feeding, dust reduction, uniform distribution, mixing, and discharging. Its feeding assembly 1 uses a carbon fiber composite material feeding plate 11 to achieve stepless tilt adjustment from 0 to 45 degrees. The plate surface is provided with anti-slip grooves and is equipped with a vibration motor to improve conveying efficiency. The bottom hinge rod 132 and the lifting cylinder 13 are driven by a universal joint. A built-in magnetostrictive displacement sensor forms a closed-loop angle control, which is particularly suitable for the stable feeding requirements of solid waste cementitious materials with large moisture content differences. The dust reduction assembly 2 adopts an arc-shaped double-layer hollow baffle structure. The dual straight shaft 24 is internally equipped with an out-of-phase rotating air intake system. The servo motor 23 drives the high-pressure atomizing nozzle through a gear set and synchronous belt to form a three-dimensional dust reduction field. The venturi tube structure dust outlet 22 uses negative pressure suction to guide dust into the bag dust collector, effectively solving the dust problem in concrete production. The distribution assembly 3 consists of four sets of counter-rotating shafts 311, with trapezoidal variable-pitch distribution plates 312 welded to their surfaces. A large helical angle at the front breaks up clumped material, while a reduced pitch at the rear achieves uniform distribution. A planetary transmission structure maintains speed synchronization. The mixing assembly 4 utilizes dual drive shafts 41 and dual rotating shafts 42, which rotate in orbital motion via a linkage belt 314. A bevel gear set meshes with an internal gear ring 44 to form a planetary gear train. The stirring rod 422 features dual helical stirring blades 423 with removable scrapers. The internal gear ring 44 drives a set of spoiler blades 442, creating a three-dimensional turbulent flow field, making it particularly suitable for homogenizing high-viscosity solid waste cementitious materials. The discharge assembly 5 achieves directional discharge through an eccentric discharge plate 511 and an adjustable inclination guide plate. The guide plate has a built-in vibrator to prevent material adhesion. A torque sensor and variable frequency speed control form a closed-loop flow control system, meeting the precise discharge requirements of solid waste concrete of varying consistencies. The device integrates various functional modules through a mechanical transmission chain to achieve efficient and uniform mixing and loading of recycled aggregates from construction waste and cementitious materials.
