Description

Technical Field

[0001] This invention relates to the field of concrete feeding technology, specifically to a concrete feeding device for solid waste cementitious materials. Background Technology

[0002] The solid waste cementitious material concrete feeding device is an automated equipment specifically designed for processing solid waste such as construction waste and industrial slag into concrete by mixing it with cementitious materials.

[0003] Against the backdrop of the industrial context of construction waste resource utilization and comprehensive treatment of industrial solid waste, traditional solid waste cementitious concrete feeding devices have exposed multiple technical bottlenecks, directly restricting the production efficiency and quality stability of recycled aggregate concrete. Existing equipment generally suffers from two major defects: First, the dust suppression system mostly uses post-installed bag filters, which cannot suppress dust generation in the initial stage of material conveying, leading to excessive dust concentration in the working environment, endangering the health of operators and causing the loss of effective components of the cementitious materials; Second, during feeding, the material dispersion system mostly relies on single-stage vibration or fixed material feeding structures, which are difficult to effectively break up and uniformly distribute agglomerated materials when dealing with common brick-concrete mixed waste in construction waste, directly affecting the workability of the concrete.

A transmission belt is mounted on the other straight shaft and the output shaft of the servo motor. An air inlet block is fixedly connected to one end of the straight shaft, and several equidistant air outlets are installed on one side of the air inlet block. A dust outlet is fixedly connected to one side of the dust suppression baffle.

[0009] As a preferred embodiment of the present invention, the equalizing component is composed of a rotating motor, which is installed on one side of the main body. Four equally spaced rotating shafts are rotatably installed inside the main body. One of the rotating shafts is connected to the output end of the rotating motor via a coupling. Several equally spaced equalizing plates are fixedly connected to the rotating shaft. Meshing gears are fixedly sleeved on the rotating shaft, and two adjacent meshing gears mesh with each other.

[0010] In a preferred embodiment of the present invention, the stirring assembly consists of two drive shafts, which are symmetrically arranged and rotatably mounted inside the main body. A linkage belt is fitted onto each drive shaft and one of the rotating shafts. A drive bevel gear is fixedly connected to one end of each drive shaft.

The drive bevel gear and the follower bevel gear mesh with each other. A stirring rod is fixedly connected to the top of each rotating shaft. A plurality of equidistant stirring blades are fixedly fitted onto the outer circumference of the stirring rod. Two symmetrically arranged rotating gears are fixedly fitted onto the stirring rod, and the two rotating gears mesh with each other.

[0011] As a preferred embodiment of the present invention, a long shaft is rotatably mounted inside the main body, and a transmission gear is fixedly sleeved on the outer circumferential surface of the long shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention achieves dust source control through the design of dust suppression components and dust outlets. The dust suppression baffle has a built-in dual linear shaft air intake system. A servo motor drives a gear set to rotate the linear shaft, creating a negative pressure airflow field in the air intake block. This, combined with the atomizing nozzle, forms a gas-liquid mixing adsorption effect, intercepting dust at the material inlet. The venturi tube structure dust outlet utilizes the fluid negative pressure effect to directionally guide unadsorbed particles into the bag filter, constructing a dual environmental protection barrier and completely solving the dust overflow pollution problem of traditional devices.

[0015] 2. This invention constructs a multi-dimensional mixing system through the arrangement of components such as a uniform distribution assembly and a stirring assembly. Four sets of parallel rotating shafts form a planetary transmission system through meshing gears. The counter-rotation of adjacent shafts generates a shear force field, which, together with the large-pitch uniform distribution plate at the front end, breaks up agglomerated materials, while the closely spaced uniform distribution plates at the rear end achieve gradient material distribution. The rotating shafts driven by dual transmission shafts form a combined revolution-rotation motion through a bevel gear set. The stirring blades and turbulence-generating blades work together to generate a three-dimensional turbulent field, which is particularly effective for high-viscosity solid waste gelling materials, improving uniformity and eliminating the material segregation phenomenon of traditional devices.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-6 A solid waste cementitious material concrete feeding device includes a main body 10. One end of the main body 10 is movably hinged to a feeding component 1 for feeding assistance. A dust suppression component 2 for dust suppression is installed on the top of the main body 10. A material distribution component 3 for material dispersion is installed at the bottom of the dust suppression component 2. A stirring component 4 for uniform stirring of the material is installed at the bottom of the stirring component 3. A discharge component 5 for discharging the material is installed at the bottom of the stirring component 4.

[0029] Furthermore, a solid waste cementitious material concrete feeding device has a main body 10 frame made of high-strength alloy steel, with a feeding assembly 1 movably connected to the top via a hinged shaft. The feeding assembly 1 consists of an adjustable-angle feeding plate 11, the surface of which is covered with a wear-resistant coating to adapt to the friction of solid waste materials. A dust suppression assembly 2 is fixedly installed on the top of the main body 10, with its dust suppression baffle 21 having an arc-shaped surrounding structure and an internal dual straight-shaft 24 air intake system. The system is driven by a servo motor 23 to drive a gear set to achieve synchronous rotation. The surface of the air intake block 242 is densely covered with atomizing nozzles, using the principle of negative pressure adsorption to suppress dust diffusion. A distribution assembly 3 is located below the dust suppression assembly 2 and consists of four sets of parallel rotating shafts 311. Each shaft surface is welded with a spiral distribution plate 312, and adjacent shafts rotate in opposite directions through meshing gears 313, forming a multi-stage dispersion effect on the material. The mixing assembly 4 employs a linkage structure of dual drive shafts 41 and a rotating shaft 42. The drive shaft 41 drives the rotating shaft 42 to revolve via a bevel gear set. Simultaneously, the gear at the end of the rotating shaft 42 meshes with the internal gear ring 44, driving the turbulence vanes 442 to generate a three-dimensional mixing flow field. The discharge assembly 5 is driven by a discharge motor 51 to rotate the discharge plate 511, which, in conjunction with the guide plate, achieves directional discharge. All components achieve a continuous operation process of feeding, dust suppression, uniform distribution, mixing, and discharge through a mechanical transmission chain, making it particularly suitable for the uniform mixing and feeding of recycled aggregates and cementitious materials from construction waste.

[0030] In this embodiment, the feeding assembly 1 is composed of a feeding plate 11, which is movably hinged to the top of the main body 10. A drive motor 12 is installed on one side of the feeding plate 11, and a drive belt 121 is sleeved on the output shaft of the drive motor 12.

[0031] Furthermore, the feeding assembly 1 is composed of a feeding plate 11 made of carbon fiber composite material, with adjustable side guards on both sides of the plate. The drive motor 12 is bolted to the side wall of the main body 10, and its output shaft is fitted with a high-strength polyurethane drive belt 121, the other end of which is connected to the main shaft of the feeding plate 11. When the motor starts, the drive belt 121 drives the feeding plate 11 to rotate around the hinge axis via friction transmission, achieving an angle adjustment of 0-45°. Anti-slip grooves are formed on the surface of the feeding plate 11, which, in conjunction with the vibrating motor, enables efficient conveying of solid waste materials. This assembly controls the feeding speed through motor speed adjustment and, in conjunction with the limit sensor on the top of the main body 10, achieves automated angle positioning, making it particularly suitable for the stable feeding requirements of solid waste cementitious materials with significant differences in moisture content.

[0032] In this embodiment, a lifting cylinder 13 is installed on one side of the main body 10, a hinge rod 132 is fixedly connected to the bottom of the feeding plate 11, a lifting shaft 131 is installed at the output end of the lifting cylinder 13, and the lifting shaft 131 and the hinge rod 132 are hinged to each other.

[0033] Furthermore, the lifting cylinder 13 is fixed to the side wall of the main body 10 via a flange, and its piston rod end is equipped with a double-eared lifting shaft 131. The hinge rod 132 welded to the bottom of the feeding plate 11 adopts a ball joint structure and forms a universal connection with the lifting shaft 131. When the cylinder extends or retracts, it drives the feeding plate 11 to rotate around the hinge shaft through the lever principle, realizing stepless angle adjustment. The cylinder has a built-in magnetostrictive displacement sensor, which feeds back the position signal of the feeding plate 11 to the control system in real time, forming a closed-loop control. This mechanism adopts a nitrogen spring auxiliary support design, which effectively reduces cylinder load fluctuations and is particularly suitable for dynamic angle adjustment scenarios when conveying large pieces of solid waste.

[0034] In this embodiment, the dust suppression component 2 is composed of a dust suppression 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 suppression baffle 21, and a drive gear 231 is installed at the output end of the servo motor 23. Two symmetrically arranged straight shafts 24 are rotatably installed inside the dust suppression baffle 21. A follower gear 241 is fixedly sleeved on the outer circumference of one of the straight shafts 24. The drive gear 231 and the follower gear 241 mesh with each other. A transmission belt 232 is sleeved on the other straight shaft 24 and the output shaft of the servo motor 23. An air inlet block 242 is fixedly connected to one end of the straight shaft 24. Several equidistant air outlets 243 are installed on one side of the air inlet block 242. A dust outlet 22 is fixedly connected to one side of the dust suppression baffle 21.

[0035] Furthermore, the dust baffle 21 adopts a double-layer hollow structure with spiral guide grooves on the inner wall. The servo motor 23 drives the drive gear 231 via a reducer, forming a 90° right-angle transmission with the driven gear. Another set of straight shafts 24 is connected to the motor shaft via a synchronous belt, achieving dual-axis out-of-phase rotation. The air inlet block 242 integrates a high-pressure fan and atomizing nozzles, generating a centrifugal airflow field during rotation. This, combined with the angle adjustment mechanism of the air outlet 243, forms a three-dimensional dust suppression area. The dust outlet 22 adopts a Venturi tube structure, utilizing negative pressure suction to guide dust into the bag filter. This component adjusts the fan speed via a frequency converter to adapt to the dust suppression requirements of solid waste materials with different particle sizes, effectively solving the dust pollution problem in concrete production.

[0036] In this embodiment, the equalizing component 3 is composed of a rotating motor 31, which is installed on one side of the main body 10. Four equally spaced rotating shafts 311 are rotatably installed inside the main body 10. One of the rotating shafts 311 is connected to the output end of the rotating motor 31 via a coupling. Several equally spaced equalizing plates 312 are fixedly connected to the rotating shaft 311. Meshing gears 313 are fixedly sleeved on the rotating shaft 311, and two adjacent meshing gears 313 mesh with each other.

[0037] Furthermore, the equalizing component 3 consists of four sets of rotating shafts 311, with trapezoidal equalizing plates 312 welded to the shaft surfaces. Adjacent shafts rotate synchronously in opposite directions via meshing gears 313. The rotating motor 31 drives the main shaft through a flexible pin coupling, and the main shaft gear drives the driven shaft gear set to form a planetary transmission structure. The equalizing 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 material distribution. This component achieves continuous lubrication through the lubrication oil circuit in the gearbox, and works in conjunction with the shaft end encoder to detect the speed synchronization, making it particularly suitable for the dispersion treatment of solid waste gelled materials containing fiber-reinforced materials.

[0038] In this embodiment, the stirring assembly 4 consists of two drive shafts 41, which are symmetrically arranged and rotatably installed inside the main body 10. The drive shafts 41 and two of the rotating shafts 311 are fitted with a linkage belt 314. One end of the drive shaft 41 is fixedly connected to a drive bevel gear 411. Two symmetrically arranged rotating shafts 42 are rotatably installed inside the main body 10. One end of the rotating shaft 42 is fixedly connected to a follower bevel gear 420. The drive bevel gear 411 and the follower bevel gear 420 mesh with each other. The top of the rotating shaft 42 is fixedly connected to a stirring rod 422. Several equally spaced stirring blades 423 are fixedly fitted on the outer circumferential surface of the stirring rod 422. Two symmetrically arranged rotating gears 421 are fixedly fitted on the stirring rod 422, and the two rotating gears 421 mesh with each other.

[0039] Furthermore, the stirring assembly 4 adopts a cross-drive structure of dual drive shafts 41 and dual rotating shafts 42. The drive shaft 41 drives the rotating shaft 42 to revolve via a linkage belt 314. The driving bevel gear 411 at the end of the rotating shaft 42 meshes with the driven bevel gear to form a planetary gear system. Double helical stirring blades 423 are welded to the surface of the stirring rod 422, and detachable scrapers are provided between adjacent stirring blades 423. The rotating gear 421 drives the internal gear ring 44 to rotate, which in turn drives the turbulence blade 442 to generate a radial stirring flow field. This assembly, through differential transmission design, forms a complex turbulent flow field in the mixing tank, which is particularly suitable for the uniform mixing of high-viscosity solid waste cementitious materials and effectively avoids the floating and separation of light materials.

[0040] In this embodiment, a long shaft 43 is rotatably mounted inside the main body 10, and a transmission gear 431 is fixedly sleeved on the outer circumferential surface of the long shaft 43. The transmission gear 431 meshes with one of the rotating gears 421. An internal gear ring 44 is rotatably mounted inside the main body 10. Several equidistant connecting rods 441 are fixedly connected to the top of the internal gear ring 44, and several equidistant turbulence vanes 442 are fixedly connected to one side of the connecting rods 441.

[0041] Furthermore, the long shaft 43 is mounted on the bottom of the main body 10 via a self-aligning roller bearing, and its end drive gear 431 meshes with the rotating gear 421. The internal gear ring 44 is axially positioned via a thrust ball bearing, and streamlined baffles 442 are welded to the surface of the connecting rod 441. When the rotating gear 421 drives the internal gear ring 44 to rotate, the baffles 442 generate an axial circulating flow field, forming a three-dimensional mixing effect with the radial flow field of the stirring blades 423. This mechanism, through gear module matching design, achieves an adjustable speed ratio between revolution and rotation, making it particularly suitable for the rapid homogenization treatment of solid waste concrete with added chemical admixtures.

[0042] In this embodiment, the discharge assembly 5 is composed of a discharge motor 51, which is installed at the bottom of the main body 10. A discharge plate 511 is installed at the output end of the discharge motor 51, and a discharge guide plate 52 is fixedly connected to the bottom of the main body 10.

[0043] Furthermore, the discharge assembly 5 is driven by a discharge motor 51 to produce an eccentric discharge plate 511, the surface of which is coated with a wear-resistant ceramic coating. The discharge guide plate 52 features an adjustable tilt angle design, adjustable from 0-30° via a hydraulic rod. When the motor drives the discharge plate 511 to rotate, the material is discharged directionally along the guide plate under centrifugal force. A vibrator is installed inside the guide plate to prevent wet and sticky materials from adhering. This assembly monitors the discharge resistance in real time using a torque sensor, and achieves closed-loop flow control in conjunction with frequency conversion speed regulation, making it particularly suitable for the precise discharge requirements of solid waste concrete with different consistencies.

[0044] A solid waste cementitious material concrete feeding device adopts a modular integrated design. The main frame 10 is constructed of high-strength alloy steel and is equipped with a continuous operation system for feeding, dust suppression, equalization, mixing, and discharging. Its feeding component 1 achieves stepless tilt adjustment from 0-45° via a carbon fiber composite feeding plate 11. Anti-slip grooves are provided on the plate surface, and a vibrating motor enhances conveying efficiency. The bottom hinge rod 132 is driven by a universal joint with the lifting cylinder 13, and a built-in magnetostrictive displacement sensor forms a closed-loop angle control, particularly suitable for the stable feeding requirements of solid waste cementitious materials with large differences in moisture content. The dust suppression component 2 adopts an arc-shaped double-layer hollow baffle structure, with an internal dual-axis 24 anti-phase rotating air intake system. A servo motor 23 drives a high-pressure atomizing nozzle through a gear set and synchronous belt to form a three-dimensional dust suppression field. The venturi tube dust outlet 22 uses negative pressure suction to guide dust into a bag filter, effectively solving the dust problem in concrete production. The equalization component 3 consists of four sets of counter-rotating shafts 311, with trapezoidal variable-pitch equalization plates 312 welded to the shaft surfaces. The large helix angle at the front breaks up agglomerated materials, while the reduced pitch at the rear achieves uniform material distribution. A planetary transmission structure maintains synchronized rotational speeds. The mixing component 4 employs a cross-drive system of dual drive shafts 41 and dual rotating shafts 42. The drive shafts 41 drive the rotating shafts 42 to revolve via a linkage belt 314. Simultaneously, a bevel gear set meshes with an internal gear ring 44 to form a planetary gear system. Double helical mixing blades 423 on the surface of the mixing rod 422 are coupled with detachable scrapers. The internal gear ring 44 drives a set of turbulent blades 442 to generate a three-dimensional turbulent flow field, making it particularly suitable for homogenizing high-viscosity solid waste cementitious materials. The discharge component 5 achieves directional discharge through an eccentric discharge plate 511 and an adjustable-angle guide plate. The guide plate has a built-in vibrator to prevent material adhesion. A torque sensor and frequency converter form a closed-loop flow control system to meet the precise discharge requirements of solid waste concrete of different consistencies. The device integrates various functional modules through a mechanical transmission chain to achieve efficient and uniform mixing and feeding of recycled aggregates and cementitious materials from construction waste.
