Description

Technical Field

[0001] The utility model relates to a material conveying system for an oil-stone separation device of asphalt recycled materials, belonging to the technical field of asphalt recycling. Background Art

[0002] Oil-stone separation is a key technology for recycling waste asphalt mixtures in road construction and maintenance. This process aims to recycle old asphalt pavement materials. By separating asphalt from aggregates (oil and stone), they can be reused in new asphalt mixtures. Due to the high viscosity of asphalt mixtures, there are problems of unsmooth or even blocked feeding during feeding. Existing oil-stone separation devices lack effective dredging structures. When there are problems with smooth feeding during the separation of oil and stone, manual workers need to enter the treatment tank to dig out materials, which poses safety hazards in operation.

[0003] To solve the above problems, we propose a material conveying system for an oil-stone separation device of asphalt recycled materials, which can solve the problem of unsmooth feeding of asphalt mixtures. Content of the Utility Model

[0004] The technical problem to be solved by the utility model: The existing asphalt mixtures have high viscosity and are prone to problems of unsmooth feeding and blockage.

[0005] To achieve the above purpose, the utility model provides a material conveying system for an oil-stone separation device of asphalt recycled materials, including an installation base plate. A separation bin is fixedly connected to the installation base plate. The bin wall inclination of the separation bin is relatively large, which is conducive to the smooth feeding of asphalt mixtures. An operation platform is fixedly connected to the separation bin. A grate screen is slidably connected to the inner bottom end of the separation bin. Longitudinally symmetric sliding rods are fixedly connected to the grate screen. A first elastic member is connected between the sliding rods and the inner wall of the separation bin. A contact plate is fixedly connected to the bottom end of the grate screen. The contact plate extends outside the separation bin. A driving motor is fixedly connected to the separation bin. A cam is fixedly connected to the output shaft of the driving motor. The cam is in extrusion cooperation with the contact plate. A conveying component for separately conveying the separated materials is arranged on the installation base plate. A material blocking component for adjusting the feeding speed is arranged in the separation bin.

[0006] In the aforementioned material conveying system for an oil-stone separation device of asphalt recycled materials, the grate screen is inclined, and a discharge port is opened on the separation bin. The lower end of the grate screen is located at the discharge port.

[0007] In the aforementioned material conveying system for an oil-stone separation device of asphalt recycled materials, laterally symmetric air arch breakers are fixedly connected to the separation bin.

[0008] The aforementioned material conveying system for an asphalt recycled material oil-stone separation device, wherein the conveying assembly includes an installation frame fixedly connected to the installation base plate. A conveyor belt is connected between the two ends of the installation frame through conveying wheels. A servo motor is fixedly connected to the installation frame, and the output shaft of the servo motor is connected to the adjacent conveying wheel. A guide plate is fixedly connected to the separation bin.

[0009] The aforementioned material conveying system for an asphalt recycled material oil-stone separation device, wherein the guide plate is inclined. The higher end of the guide plate is located at the discharge port, and the lower end is located at the installation frame, for conveying the material discharged from the discharge port onto the conveyor belt.

[0010] The aforementioned material conveying system for an asphalt recycled material oil-stone separation device, wherein the baffle assembly includes longitudinally symmetrical rotating plates. The longitudinally symmetrical rotating plates are rotatably connected to the middle part inside the separation bin. A rotating column is fixedly connected to the rotating plate, and the rotating column extends outside the separation bin. Longitudinally symmetrical clamping rods are slidably connected to the separation bin, and a second elastic member is connected between the clamping rods and the separation bin.

[0011] The aforementioned material conveying system for an asphalt recycled material oil-stone separation device, wherein a circle of grooves adapted to the clamping rods is formed on the rotating column.

[0012] The beneficial effects achieved by the present utility model are as follows: 1. The asphalt mixture is introduced into the separation bin. Due to the large inclination angle of the bin wall of the separation bin, it is beneficial for the smooth feeding of the asphalt mixture. Under the action of the air arch breaker, the inside of the separation bin can also be directly dredged to avoid the need for manual material removal due to the blockage of the asphalt mixture. After the asphalt mixture falls onto the grid screen, the grid screen vibrates to screen the asphalt mixture. The asphalt passes through the grid screen and directly falls downward, while the separated oil-stone is conveyed to the right through the inclined grid screen and then discharged from the discharge port.

[0013] 2. The asphalt passes through the grid screen and directly falls onto the conveyor belt on the left. The oil-stone discharged from the discharge port is guided and conveyed to the conveyor belt on the right through the guide plate, and the asphalt and oil-stone are conveyed by the two conveyor belts.

[0014] 3. The asphalt mixture in the separation bin will be blocked by the rotating plates. The asphalt mixture needs to be conveyed downward through the gap between the front and rear rotating plates to avoid a large amount of asphalt mixture directly piling up on the grid screen and affecting the separation effect.

Detailed implementation manners

[0021] The following will further illustrate the present utility model in conjunction with specific embodiments. It should also be noted that unless otherwise clearly specified and limited, terms such as: setting, installation, connection, and coupling should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] Embodiment 1: A material conveying system for an asphalt recycled material oil-stone separation device, as Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes an installation base plate 1, a separation bin 2, an operation platform 3, an air arch breaker 4, a grate screen 5, sliding rods 6, a first elastic member 7, a contact plate 8, a driving motor 9, a cam 91, a conveying assembly, and a material blocking assembly. The left part of the installation base plate 1 is fixedly connected with the separation bin 2. The wall inclination of the separation bin 2 is relatively large, which is beneficial to the smooth feeding of the asphalt mixture. The rear side of the separation bin 2 is fixedly connected with the operation platform 3. Air arch breakers 4 are fixedly connected to both the left and right sides of the upper part of the separation bin 2. The lower part inside the separation bin 2 is slidably connected with a grate screen 5. The grate screen 5 is inclined. An outlet is opened at the lower right side of the separation bin 2. The lower end of the grate screen 5 is located at the outlet. The left part of the grate screen 5 is fixedly connected with symmetric front and rear sliding rods 6. A first elastic member 7 is connected between the sliding rods 6 and the inner wall of the separation bin 2. The lower left side of the grate screen 5 is fixedly connected with a contact plate 8. The contact plate 8 extends outside the separation bin 2. The lower left side of the separation bin 2 is fixedly connected with a driving motor 9. A cam 91 is fixedly connected to the output shaft of the driving motor 9. The cam 91 is in pressing cooperation with the contact plate 8. A conveying assembly for separately conveying the separated materials is provided on the installation base plate 1. A material blocking assembly for adjusting the feeding speed is provided inside the separation bin 2.

[0023] When using this device, the staff starts the driving motor 9. The rotation of the output shaft of the driving motor 9 drives the cam 91 to rotate. The rotation of the cam 91 presses the contact plate 8 to move downward. The downward movement of the contact plate 8 drives the grate screen 5 to slide downward. The sliding rods 6 slide downward accordingly, and the first elastic member 7 deforms. When the cam 91 rotates to separate from the contact plate 8, under the action of the reset of the first elastic member 7, the sliding rods 6 drive the grate screen 5 to slide upward and reset. By controlling the continuous rotation of the cam 91, the vibration of the grate screen 5 can be controlled. Then the staff feeds the asphalt mixture into the separation bin 2. Since the wall inclination of the separation bin 2 is relatively large, it is beneficial to the smooth feeding of the asphalt mixture. Under the action of the air arch breaker 4, the inside of the separation bin 2 can also be directly dredged to avoid the need for manual material removal due to the blockage of the asphalt mixture. After the asphalt mixture falls onto the grate screen 5, the asphalt mixture is screened by the vibrating grate screen 5. The asphalt passes through the grate screen 5 and directly falls downward, while the separated oil stones are conveyed to the right through the inclined grate screen 5 and then discharged from the outlet. The separated asphalt and oil stones are separately conveyed by the conveying assembly, and the material blocking assembly can adjust the feeding speed of the asphalt mixture in the separation bin 2 so that the grate screen 5 can separate. When the use of this device is completed, the staff turns off the driving motor 9.

[0024] Embodiment 2: On the basis of Embodiment 1, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, the conveying assembly includes an installation frame 10, a conveyor belt 11, a servo motor 12 and a guide plate 13. Both the left and right parts of the installation base plate 1 are fixedly connected with the installation frame 10. The conveyor belt 11 is connected between the left and right parts of the installation frame 10 through conveying wheels. The servo motor 12 is fixedly connected to the front side of the left part of the installation frame 10, and the output shaft of the servo motor 12 is connected to the adjacent conveying wheel. The guide plate 13 is fixedly connected to the lower right part of the separation bin 2. The guide plate 13 is inclined and is used to convey the materials discharged from the discharge port onto the conveyor belt 11.

[0025] When using this device, the asphalt passes through the grid screen 5 and directly falls onto the conveyor belt 11 on the left. The oil-stone separated by the grid screen 5 is discharged from the discharge port, and then is guided and conveyed onto the conveyor belt 11 on the right through the guide plate 13. By operating the servo motor 12 to rotate the conveyor belt 11, the asphalt and the oil-stone can be conveyed respectively.

[0026] As Figure 4 and Figure 5 shown in the figure, the material blocking assembly includes a rotating plate 14, a rotating column 15, a clamping rod 16 and a second elastic member 17. The rotating plates 14 that are symmetrically arranged front and back are rotatably connected to the middle part inside the separation bin 2. The right end of the rotating plate 14 is fixedly connected with the rotating column 15. The rotating column 15 extends outside the separation bin 2. The clamping rods 16 that are symmetrically arranged front and back are slidably connected to the middle part on the right side of the separation bin 2. A circle of slots adapted to the clamping rods 16 are formed on the rotating column 15. The second elastic member 17 is connected between the clamping rod 16 and the separation bin 2.

[0027] When using this device, the asphalt mixture inside the separation bin 2 will be blocked by the rotating plate 14. The asphalt mixture needs to be conveyed downward through the gap between the front and rear rotating plates 14 to prevent a large amount of asphalt mixture from directly piling up on the grid screen 5 and affecting the separation effect. At the same time, under the action of the second elastic member 17, the clamping rod 16 can slide upward to separate from the rotating column 15, so that the rotating column 15 can drive the rotating plate 14 to rotate and adjust the opening size, thereby adjusting the feeding speed.

[0028] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
