Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste asphalt stripping equipment, and in particular to a waste asphalt stripping equipment. Background Technology
[0002] Asphalt pavements are subjected to erosion from natural factors such as sunlight, rainfall, and air, as well as vehicle loads. Over time, the asphalt within the pavement undergoes qualitative changes, including volatilization and oxidation. Aging asphalt exhibits significantly deteriorated properties, leading to dryness, brittleness, and eventually cracking, severely reducing traffic safety. Therefore, it is essential to repair or replace aging asphalt pavements promptly.
[0003] A search revealed Chinese Patent Publication No. CN220071799U, which discloses a waste asphalt stripping device, comprising a first housing, a crushing mechanism, a centrifugal mechanism, and a screening mechanism. The housing has a feed inlet at its top. The crushing mechanism is located within the first housing and is used to crush the waste asphalt. The centrifugal mechanism is located below the crushing mechanism and is used to centrifugally strip the waste asphalt. The screening mechanism is located below the centrifugal mechanism and is used to screen the material according to different particle sizes. This device solves the problems of low stripping efficiency and poor stripping effect found in existing waste asphalt stripping devices.
[0004] While the above technologies have achieved improved asphalt stripping effect, the centrifugal discs, lacking a sediment discharge structure, cause sediment to accumulate, requiring frequent shutdowns for cleaning. This not only affects production efficiency but also increases maintenance costs. Therefore, a waste asphalt stripping device is proposed to solve these problems. Utility Model Content

[0031] 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.
[0032] Reference Figures 1-3This utility model provides an embodiment of a waste asphalt stripping device, including a shell 1. A support 2 is fixedly connected to the outer wall of the shell 1 to provide support for the shell 1. A crushing device 3 for pre-processing waste asphalt is set at the top of the shell 1. The crushing rollers inside the crushing device 3 are synchronously crushed by gears. A feeding element 8 with a square upper end and a round lower end is fixedly connected to the bottom of the crushing device 3. A support plate 5 for providing support for a motor 61 is fixedly connected to the outer wall of the shell 1. A heat dissipation component 6 is set at the top of the support plate 5 to move the installation position of the motor 61 from inside the equipment to the outside, reducing the risk of high temperature operation caused by the enclosed space and limited airflow, and significantly improving heat dissipation efficiency. A discharge hopper 7 is fixedly connected to the outer wall of the shell 1. There are two sets of discharge hoppers 7, which are mirror-distributed along the central axis of the shell 1. The shell 1 is equipped with a discharge component 4 that optimizes the structure of the centrifugal disc 41 to effectively discharge the sediment in the centrifugal disc 41 and improve production efficiency.
[0033] The discharge assembly 4 includes a centrifugal turntable 41. Several support rods 42 are fixedly connected to the top of the centrifugal turntable 41, and these support rods 42 are arranged in a ring along a base 43. The top of each support rod 42 is fixedly connected to the base 43. A ring 44 is fixedly connected to the outer wall of the centrifugal turntable 41 to facilitate its rotation within a fixed ring 45 without it falling off. A fixed ring 45 with an internal groove is fixedly connected to the inside of the housing 1. The bottom of the fixed ring 45 is fixedly connected to a groove on its outer wall. The discharge ring 46 of the hole has a baffle 47 slidably connected inside. The outer wall of the ring 44 is rotatably connected to the inside of the fixed ring 45. When the sediment inside the centrifugal disc 41 is to be discharged, the handle 48 is manually held on the outer wall of the housing 1 and pulled outward, which drives the baffle 47 inside the discharge ring 46 to be pulled outward, so that the sediment inside the centrifugal disc 41 falls from the discharge ring 46 into the discharge pipe 49 and flows out, while the asphalt thrown out by centrifugal force is discharged from the discharge hopper 7.
[0034] Reference Figure 1 , Figure 3 , Figure 4A feed pipe 49 is fixedly connected to the bottom of the baffle 47. A handle 48 for easy removal of the baffle 47 is fixedly connected to the outer wall of the baffle 47. The outer wall of the feed pipe 49 is fixedly connected to the inside of the housing 1. The outer wall of the handle 48 is slidably connected to the outer wall of the housing 1. The heat dissipation assembly 6 includes a motor 61. The bottom of the motor 61 is fixedly connected to the top of the support plate 5. A crossbar 62 is fixedly connected to the output shaft of the motor 61. A first bevel gear 63 is fixedly connected to the front end of the crossbar 62. A second bevel gear 64 meshes with the outer wall of the first bevel gear 63. A dust cover 65 with a spherical top and a smooth surface that is narrow at the top and wide at the bottom is fixedly connected to the top of the chassis 43. The bottom of the first bevel gear 63 is fixedly connected to the top of the chassis 43. The outer wall of the dust cover 65 has a hole, and the outer wall of the first bevel gear 63 is rotatably connected to the inside of the hole. The dust cover 65 provides protection for the first bevel gear 63 and the second bevel gear 64, extending their service life. The outer wall of the crossbar 62 is rotatably connected to the outer wall of the housing 1. The outer walls of the first bevel gear 63 and the second bevel gear 64 are rotatably connected to the inside of the dust cover 65. When the asphalt is to be peeled off by centrifugal force, the motor 61 is turned on, causing the crossbar 62 to rotate, which drives the first bevel gear 63 to rotate and simultaneously causes the second bevel gear 64 to rotate. This causes the chassis 43 connected to the second bevel gear 64 to rotate, which in turn drives the support rod 42 to rotate, causing the ring 44 on the outer wall of the centrifugal turntable 41 to rotate inside the fixed ring 45.
[0035] Working principle: When using the centrifugal disc 41, to discharge the sediment inside the centrifugal disc 41, manually hold the handle 48 on the outer wall of the housing 1 and pull it outward. This will cause the baffle 47 inside the discharge ring 46 to be pulled outward, so that the sediment inside the centrifugal disc 41 falls from the discharge ring 46 into the discharge pipe 49 and flows out. The asphalt thrown out by centrifugal force is discharged from the discharge hopper 7. When the asphalt needs to be peeled off by centrifugal force, turn on the motor 61, so that the crossbar 62 rotates and drives the first bevel gear 63 to rotate, and at the same time, the second bevel gear 64 rotates. This causes the chassis 43 connected to the second bevel gear 64 to rotate, which drives the support rod 42 to rotate, and causes the ring 44 on the outer wall of the centrifugal disc 41 to rotate inside the fixed ring 45.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
