Description

Technical Field

[0001] This utility model belongs to the field of asphalt recycling powder processing technology, specifically relating to a shearing spiral-type wet asphalt station recycling powder auxiliary feeding device. Background Technology

[0002] Wet asphalt plant recycled powder is a fine powdery substance produced during the asphalt mixture production process. It is mainly composed of mineral powder and unburned asphalt, and has a certain degree of viscosity and moisture content. In the production process of wet asphalt plants, the treatment and recycling of this powder is of great significance for improving production efficiency, reducing costs, and minimizing environmental pollution.

[0003] In the production process of wet asphalt plants, the handling and feeding of recycled powder has always been a critical link. Existing recycled powder handling methods mainly have the following problems: easy agglomeration and blockage: During the discharge process, traditional recycled powder handling devices lack effective vibration and shearing mechanisms, causing wet recycled powder to easily agglomerate at the discharge port, leading to blockage and affecting production efficiency; inability to discharge quantitatively: Most existing discharge methods rely on gravity or simple conveying devices, which cannot achieve quantitative discharge of materials and make it difficult to accurately control the amount of recycled powder used; difficult cleaning: Recycled powder easily forms a scale layer on the inner wall of the storage shell and related components, and traditional cleaning methods are ineffective and difficult to completely remove the attached material. Utility Model Content

[0004] The purpose of this invention is to provide a shearing spiral-type wet asphalt station recycling powder auxiliary feeding device, which aims to solve the problems mentioned in the background art.

[0005] A shear-spiral conveyor-type wet asphalt station recycling powder auxiliary feeding device, comprising,

[0006] A protective shell and a storage shell, wherein the storage shell is embedded in the inner wall of the protective shell;

[0007] A discharge assembly, located inside the storage shell, comprises a vibrating plate, a drive rod, a return spring, ball bearings, a lifting block, a mounting frame, a rotating rod, a blade, and a drive assembly. The vibrating plate is slidably embedded in the bottom of the inner wall of the storage shell. The drive rod is fixedly mounted in the bottom of the outer wall of the vibrating plate. The return spring is sleeved on the outer wall of one end of the drive rod. The ball bearings are rotatably embedded in a groove in the inner wall of the bottom end of the drive rod. The lifting block is slidably embedded in the top of the inner wall of the storage shell. The rotating rod is rotatably inserted into the outer wall of the mounting frame. The blade is embedded in the inner wall of the rotating rod. The drive plate is rotatably embedded in the inner wall of the protective shell. The drive plate and the ball bearings are matched. A discharge pipe is embedded in the inner wall of the protective shell, and a helical rod is rotatably embedded in the inner wall of the discharge pipe. One end of the discharge pipe is inserted into the interior of the storage shell, and the discharge pipe matches the opening of the vibrating plate.

[0008] Furthermore, the drive assembly includes a cleaning motor, a drive gear, a driven gear, a compression cylinder, a vibration motor, a transmission wheel, and a mounting port.

[0009] Furthermore, the cleaning motor is fixedly mounted on the top of the outer wall of the storage shell via a bracket, the driving gear is fixedly mounted on the outer wall of the output end of the cleaning motor, the driven gear is fixedly mounted on the center of the top of the outer wall of the mounting frame via a rotating shaft, the driving gear and the driven gear are meshed and connected, the squeezing cylinder is fixedly mounted on the top of the outer wall of the storage shell, and the squeezing cylinder is fixedly mounted on the top of the outer wall of the lifting block.

[0010] Furthermore, the vibration motor is fixedly mounted on the outer wall of the protective shell, the transmission wheel is fixedly mounted on the outer wall of the vibration motor, the transmission wheel is connected to the drive plate through transmission, and the mounting port is opened on the outer wall of the protective shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] A vibrating motor drives a transmission wheel, which in turn causes the drive plate to periodically impact the ball bearings, generating high-frequency vibration in the drive rod. Combined with the elastic reset of the return spring, this creates a continuous vibration effect, effectively preventing wet recycled powder from clumping and clogging at the discharge port. A spiral rod is built into the discharge pipe and driven by a dedicated discharge motor to achieve quantitative forced discharge of materials. The vibration of the vibrating plate and the shearing conveying of the spiral rod create a synergistic effect, ensuring continuous and stable output of high-viscosity materials. The cleaning motor drives the rotating rod through a gear set to rotate the blades, while the extrusion cylinder controls the lifting block to move vertically. Under the combined motion of revolution and rotation, the blades can perform three-dimensional cleaning of the inner wall of the storage shell, the bottom of the mounting frame, and the surface of the vibrating plate. The blades are installed at a special angle, creating a shearing airflow during rotation. Combined with the shaking action of the vibrating plate, this effectively peels off the attached materials, preventing the formation of a scale layer. Attached Figure Description

[0023] Please see Figure 1-3 The technical solution provided in this embodiment is as follows:

[0024] A shear-spiral conveyor-type wet asphalt station recycling powder auxiliary feeding device, comprising,

[0025] The protective shell 1 and the storage shell 2 are embedded in the inner wall of the protective shell 1;

[0026] The discharge assembly is located inside the storage shell 2, and includes a vibrating plate 13, a drive rod 14, a return spring 15, a ball bearing 16, a drive plate 17, a lifting block 18, a mounting bracket 19, a rotating rod 20, a blade 21, and a drive assembly. The vibrating plate 13 is slidably embedded in the bottom of the inner wall of the storage shell 2, the drive rod 14 is fixedly installed in the bottom of the outer wall of the vibrating plate 13, the return spring 15 is sleeved on the outer wall of one end of the drive rod 14, and the ball bearing 16 is rotatably embedded in the groove on the inner wall of the bottom end of the drive rod 14. The lifting block 18 is slidably embedded in the top of the inner wall of the storage shell 2. The rotating rod 20 is rotatably inserted into the outer wall of the mounting bracket 19.

[0027] In a specific embodiment of this utility model, the vibration motor 7 drives the transmission wheel 8, which in turn drives the drive plate 17 to periodically impact the ball bearing 16, causing the drive rod 14 to generate high-frequency vibration. Combined with the elastic reset of the return spring 15, a continuous vibration effect is formed, effectively preventing the wet recycled powder from clumping and clogging at the discharge port. The discharge pipe 11 has a built-in spiral rod 12, which is driven by a dedicated discharge motor 10 to achieve quantitative forced discharge of materials. The vibration of the vibrating plate 13 and the shearing conveying of the spiral rod 12 form a synergistic effect, ensuring continuous and stable output of high-viscosity materials. The cleaning motor 3 drives the rotating rod 20 through the gear set to drive the blade 21 to rotate. At the same time, the extrusion cylinder 6 controls the lifting block 18 to move vertically. Under the combined motion of revolution and rotation, the blade 21 can perform three-dimensional cleaning of the inner wall of the storage shell 2, the bottom of the mounting bracket 19, and the surface of the vibrating plate 13. The blade 21 is installed at a special angle, which forms a shearing airflow during rotation. Combined with the shaking action of the vibrating plate 13, it effectively peels off the attached materials and avoids the formation of a scale layer.

[0030] Specifically, the cleaning motor 3 is fixedly mounted on the top of the outer wall of the storage shell 2 via a bracket, the driving gear 4 is fixedly mounted on the outer wall of the output end of the cleaning motor 3, the driven gear 5 is fixedly mounted on the center of the top of the outer wall of the mounting bracket 19 via a rotating shaft, the driving gear 4 and the driven gear 5 are meshed and connected, the squeezing cylinder 6 is fixedly mounted on the top of the outer wall of the storage shell 2, and the squeezing cylinder 6 is fixedly mounted on the top of the outer wall of the lifting block 18.

[0031] In a specific embodiment of this utility model, the compression cylinder 6 is fixedly installed at the top of the outer wall of the lifting block 18, which can ensure the stability of the lifting.

[0034] Specifically, the blade 21 is matched with the lifting block 18, and the blade 21 is matched with the vibrating plate 13.

[0035] In a specific embodiment of this utility model, the blade 21 is matched with the vibrating plate 13 to achieve cleaning of the vibrating plate 13.

[0036] Specifically, a discharge motor 10 is fixedly installed at the center of the bottom of the outer wall of the discharge pipe 11, and the output end of the discharge motor 10 is fixedly installed at the center of the bottom of the outer wall of the screw rod 12.

[0037] In a specific embodiment of this utility model, the output end of the discharge motor 10 is fixedly located at the center of the bottom of the outer wall of the screw rod 12, which can ensure continuous driving of the screw rod 12.

[0038] Working principle:

[0039] Wet asphalt recovery powder enters the storage shell 2 through the feed inlet (not shown) at the top of the storage shell 2. The embedded design of the storage shell 2 ensures dust sealing. After the power is turned on, the control system initializes, and each drive component (vibration motor 7, discharge motor 10, cleaning motor 3, extrusion cylinder 6) enters standby mode. Vibration motor 7 starts and drives drive plate 17 to rotate periodically through transmission wheel 8. The protrusion of drive plate 17 hits ball bearing 16, pushing drive rod 14 upward. The return spring 15 then rebounds, forming high-frequency vibration. Vibration plate 13 vibrates continuously under the drive of drive rod 14, loosening the recovery powder at the bottom of storage shell 2 and discharging it evenly to prevent agglomeration and blockage. Discharge motor 10 drives screw rod 12 to rotate at high speed. The material enters discharge pipe 11 through the opening of vibration plate 13. The spiral blades of screw rod 12 shear and propel the material to achieve quantitative distribution. Continuous forced discharge: The cleaning motor 3 drives the rotating rod 20 and blade 21 to revolve through the meshing of the driving gear 4 and the driven gear 5. The extrusion cylinder 6 pushes the lifting block 18 to move vertically periodically, so that the blade 21 rotates along the axis of the rotating rod 20 while revolving, forming a three-dimensional cleaning trajectory. The cutting edge of the blade 21 scrapes the inner wall of the storage shell 2, the bottom of the mounting bracket 19 and the surface of the vibrating plate 13 at a special angle to peel off the attached material. The shearing airflow generated during the rotation and the vibration of the vibrating plate 13 work together to further remove residual powder and prevent scaling. The control system adjusts the frequency of the vibrating motor 7 and the speed of the screw rod 12 in real time according to the moisture content of the material to optimize the discharge efficiency. The lifting frequency of the extrusion cylinder 6 matches the speed of the cleaning motor 3 to ensure that the blade 21 covers the entire cleaning area. The elastic sealing layer of the protective shell 1 isolates external vibration and avoids equipment resonance damage.
