Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture separation technology, and more specifically, to a waste asphalt mixture oil-stone separation device. Background Technology

[0002] In the field of road construction and maintenance, asphalt-aggregate separation is a key step in realizing the recycling of waste asphalt, saving resources, and reducing costs. Existing technologies, such as the asphalt-aggregate separation device disclosed in document CN210730103U, while meeting the requirements for asphalt-aggregate separation to a certain extent, still have shortcomings in practical use.

[0003] The existing device's filter screen is rotatably connected at one end via a hinge shaft. During the screening process, the filter screen can only swing around the hinge shaft. This single mode of movement results in a limited range of motion for the part of the filter screen near the hinge shaft, leading to significantly lower screening efficiency in this area compared to other regions. Furthermore, due to the restricted overall movement of the filter screen, it cannot effectively screen the asphalt mixture, easily causing material accumulation and further reducing screening efficiency. Utility Model Content

[0004] Based on the aforementioned technical problem that "the filter screen can only swing around the hinge axis, and this single movement mode results in a small range of motion for the part of the filter screen near the hinge axis, leading to a much lower screening efficiency in this area compared to other areas. At the same time, due to the limited overall movement of the filter screen, it is unable to effectively screen the asphalt mixture, which easily leads to material accumulation and further reduces screening efficiency," this utility model proposes a waste asphalt mixture oil-stone separation device.

[0005] This utility model proposes a waste asphalt mixture oil-stone separation device, which includes an installation sleeve, a swaying ring, a support component, a swing transmission mechanism, and a drive assembly.

[0010] The output end of the drive component is connected to the first rotating shaft to drive the swing transmission mechanism, so that the swing ring swings in the swing groove.

[0011] Preferably, the support member includes a support frame, which has a cross-shaped structure. Each end of the support frame is fixedly connected to a fixing plate. Each fixing plate has a fixing hole on its outer wall, and the fixing hole is connected to the device by bolts.

[0012] Preferably, a discharge net is fixedly connected to the top of the swaying ring, and the discharge net has a ring structure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-3 As shown, a waste asphalt mixture oil-stone separation device includes an installation sleeve 13, a swaying ring 15, a support component, a swaying transmission mechanism, and a drive assembly.

[0027] The mounting sleeve 13 has an annular swaying groove 14 extending coaxially with itself on its inner wall;

[0028] The swaying ring 15 slides in conjunction with the swaying groove 14, and a filter screen 16 is fixedly installed on its inner circumference;

[0029] The support is fixedly connected inside the device, and its top is fixedly connected to a vertically extending support shaft 9;

[0030] The swing transmission mechanism includes a second swing arm 8 rotatably connected to the support shaft 9, a third rotating shaft 7 rotatably connected to the free end of the second swing arm 8, the top of the third rotating shaft 7 being fixedly connected to the bottom circular part of the filter screen 16, a connecting arm 6 being fixedly connected to the outside of the third rotating shaft 7, a second rotating shaft 5 rotatably connected to the end of the connecting arm 6, a first swing arm 4 being fixedly connected to the bottom of the second rotating shaft 5, and a first rotating shaft 3 being fixedly connected to the end of the first swing arm 4.

[0031] The output end of the drive component is connected to the first rotating shaft 3 to drive the swing transmission mechanism, so that the swing ring 15 swings in the swing groove 14.

[0032] The filter screen in the device is connected to a hinge shaft at one end. During the screening process, the filter screen can only swing around the hinge shaft. This single movement method results in a small range of motion for the part of the filter screen near the hinge shaft, causing the screening efficiency in this area to be much lower than in other areas. At the same time, because the overall movement of the filter screen is restricted, it cannot effectively screen the asphalt mixture, which easily leads to material accumulation and further reduces the screening efficiency.

[0033] In the above-described structure of this device, by setting up the mounting sleeve 13, the swaying ring 15, the support member, the swaying transmission mechanism and the drive assembly, the filter screen 16 is allowed to sway, so that each area of ​​the filter screen 16 can obtain sufficient activity space, avoiding the problems of low local screening efficiency and material accumulation, and improving the efficiency and effect of oil-stone separation.

[0034] In some embodiments, such as Figure 2 As shown, the support includes a support frame 10, which has a cross-shaped structure. Each end of the support frame 10 is fixedly connected to a fixing plate 11. The outer wall of the fixing plate 11 is provided with fixing holes 12, and the fixing holes 12 are connected to the device by bolts.

[0035] The cross-shaped support frame 10 is connected to the device through the fixing plate 11 and fixing hole 12, providing stable support for the support shaft 9.

[0036] In some embodiments, such as Figure 1 As shown, a discharge net 20 is fixedly connected to the top of the shaking ring 15, and the discharge net 20 has a ring structure.

[0037] The discharge screen 20 provides a discharge channel for the separated coarse materials such as asphalt. The annular discharge screen 20 works in conjunction with the filter screen 16 to guide the coarse materials such as asphalt separated on the filter screen 16 to move towards the edge and be discharged.

[0038] In some embodiments, the diameter of the inner hole of the discharge screen 20 is the same as the diameter of the filter screen 16, and the mesh size of the discharge screen 20 is larger than that of the filter screen 16, so that the separated coarse materials such as asphalt can pass smoothly through the discharge screen 20 and be discharged.

[0039] In some embodiments, a first connecting pipe 17 is fixedly connected to the top of the discharge mesh 20, and the diameter of the inner hole of the first connecting pipe 17 is the same as the diameter of the inner hole of the discharge mesh 20. The fact that the inner hole diameter of the first connecting pipe 17 is the same as the inner hole diameter of the discharge mesh 20 improves the smoothness of the discharge channel.

[0040] In some embodiments, such as Figure 2As shown, a rubber sleeve 18 is coaxially sleeved at the top of the first connecting pipe 17. The rubber sleeve 18 forms a tapered curved through hole from the middle to both ends. The minimum diameter of the through hole is two-thirds of the diameter of the filter screen 16, and the maximum diameter is the same as the diameter of the filter screen 16. The design of the tapered curved through hole plays a role in gathering and guiding fine materials such as asphalt.

[0041] In some embodiments, such as Figure 1 As shown, a second connecting pipe 19 is fixedly connected to the top of the rubber sleeve 18. The inner diameter of the second connecting pipe 19 is the same as the inner diameter of the first connecting pipe 17.

[0042] In some embodiments, such as Figure 2 As shown, the drive assembly includes a frame 1 and a stepper motor 2 fixedly connected to the outer wall of the frame 1. The output end of the stepper motor 2 is fixedly connected to the first rotating shaft 3.

[0043] Working principle: When the stepper motor 2 is started, its output end drives the first rotating shaft 3 to rotate. When the first rotating shaft 3 rotates, it drives the first swing arm 4 to swing. The first swing arm 4 drives the connecting arm 6 to move through the second rotating shaft 5. The connecting arm 6 then drives the second swing arm 8 to rotate around the support shaft 9 through the third rotating shaft 7. At the same time, the third rotating shaft 7 drives the filter screen 16 to swing in the shaking groove 14.

[0044] This oscillation allows all parts of the filter screen 16 to have a large range of motion. After the waste asphalt mixture enters the filter screen 16, the stones and asphalt can be separated more fully under its oscillation. The separated fine materials such as asphalt fall through the filter screen 16, while the larger stones are gradually moved towards the discharge screen 20 under the oscillation of the filter screen 16 and discharged through the discharge screen 20.

[0045] The second connecting pipe 19 can be fixedly installed at the feeding port. When the shaking ring 15 drives the discharge net 20 to shake, the second connecting pipe 19 can remain stationary and stably convey the mixture.

[0046] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
