Description

Technical Field

[0001] This utility model relates to the field of RAP oil-stone separation technology, and in particular to a RAP oil-stone separation device. Background Technology

[0002] With continuous economic development, the construction scale of asphalt pavement in my country has gradually increased. During long-term use, asphalt pavement is subjected to natural conditions such as heat, oxygen, sunlight, and water, as well as traffic loads, leading to asphalt aging and aggregate stripping, thus reducing the performance of the asphalt pavement and causing various pavement defects. In recent years, with the increasing awareness of environmental protection, pavement recycling technology has developed rapidly. This technology involves milling, crushing, screening, and recycling of old pavement asphalt mixtures. Milling is the primary method for recycling old pavement asphalt mixtures. This method makes it relatively easy to separate the asphalt and aggregate from coarse RAP material after milling. However, the coarse RAP material needs to be heated during the separation process. For example, Chinese patent CN216275103U discloses an asphalt-aggregate separation device for fine-particle RAP material in highways, but this device has low heating efficiency and cannot continuously heat large quantities of material.

[0003] Therefore, in order to address the above problems, a RAP oil-stone separation device is proposed to solve them. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a RAP oil-stone separation device that can continuously heat RAP materials.

[0005] The technical solution to the technical problem solved by this utility model is as follows: A RAP oil-stone separation device includes a conveyor belt, which conveys materials into a heating tank. The heating tank is equipped with multiple heating plates, which heat the materials. The heating plates are provided with discharge ports, and the discharge ports of different layers of heating plates are arranged in a spiral pattern. Multiple scrapers are provided on the heating plates.

[0006] The conveyor belt transports the material into the heating tank, where it is heated by multiple layers of heating plates. The material on the heating plates falls from the discharge port onto the heating plates below, improving the heating effect and extending the heating time. Multiple scrapers move the material along the heating plates, ensuring that the material is heated by the multiple layers of heating plates.

[0007] Preferably, the heating plate is set on the positioning platform, multiple positioning platforms are set on the inner wall of the heating barrel, the heating plate has a cavity inside, and multiple sets of heating wires are set in the cavity.

[0008] Heating is achieved through heating wires inside the cavity of the heating plate, which prevents materials from contaminating the heating wires while still achieving the desired heating effect.

[0009] Preferably, a main shaft is vertically installed inside the heating tank, passing through multiple heating plates. Multiple mounting plates are installed on the main shaft, located on the heating plates, and multiple scrapers are installed on the mounting plates.

[0010] The main shaft drives the mounting plate and scraper to rotate. The scraper pushes the material to move on the heating plate, so that the heating plate heats the material. At the same time, it pushes the material from the discharge port into the lower heating plate.

[0011] Preferably, multiple mounting heads are evenly arranged on the mounting plate, and the mounting heads are connected to the handle of the scraper. A reinforcing plate is provided on the scraper, which is horizontally positioned on the upper part of the scraper. A baffle is provided on the scraper, which is vertically positioned and connected to the reinforcing plate.

[0012] The reinforcing plate on the scraper enhances its structural strength and prevents deformation. The baffle on the scraper reduces the amount of material entering the mounting plate during movement.

[0013] Preferably, a speed reducer is connected to the lower part of the main shaft, and the speed reducer is located below the heating tank and connected to the motor.

[0014] Preferably, a discharge pipe is provided at the bottom of the heating barrel, which is connected to the discharge port of the lower heating plate. A feed chute is provided at the top of the heating barrel, which is offset from the discharge port of the upper heating plate and is located below the conveyor belt.

[0015] The heated material falls into the discharge pipe and is discharged from the discharge pipe to enter the next process, realizing RAP oil-stone separation.

[0016] Preferably, a flue pipe is installed on the heating barrel, and the flue pipe is connected to a flue gas treatment device.

[0017] The flue gas treatment device collects and treats the flue gas generated during asphalt heating.

[0018] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0019] The conveyor belt transports the material to the heating plate of the heating tank. The main shaft drives the mounting plate and scraper to rotate. The scraper pushes the material to rotate on the heating plate. The material falls from the discharge port into the next layer of heating plate for further heating. By heating the material through multiple layers of heating plates, the heating time is extended and the heating effect is improved. Attached Figure Description

[0027] like Figures 1 to 4 As shown, a RAP (Rapid Alkali) oilstone separation device includes a conveyor belt 1, which transports material into a heating tank 2. The heating tank 2 contains multiple heating plates 3, which heat the material. Each heating plate 3 has a discharge port 5, arranged in a spiral pattern. Multiple scrapers 4 are mounted on each heating plate 3. The conveyor belt 1 transports the material into the heating tank 2, where it is heated by passing through the multiple heating plates 3. Material on the heating plates 3 falls from the discharge port 5 onto the lower heating plates 3, extending the heating time. The multiple scrapers 4 move the material along the heating plates 3, ensuring the material is heated by the multiple heating plates 3.

[0028] The heating plate 3 is mounted on the positioning platform 6, and multiple positioning platforms 6 are mounted on the inner wall of the heating barrel 2. The heating plate 3 has a cavity inside, and multiple sets of heating wires are installed in the cavity. Heating is achieved through the heating wires in the cavity of the heating plate 3, which can prevent the materials from contaminating the heating wires while achieving the heating effect.

[0029] A main shaft 7 is vertically installed inside the heating tank 2. The main shaft 7 passes through multiple heating plates 3. Multiple mounting plates 8 are installed on the main shaft 7, which are located on the heating plates 3. Multiple scrapers 4 are installed on the mounting plates 8. The main shaft 7 drives the mounting plates 8 and scrapers 4 to rotate. The scrapers 4 push the material to move on the heating plates 3, so that the heating plates 3 heat the material. At the same time, the material is pushed from the discharge port 5 into the lower heating plate 3.

[0030] Multiple mounting heads 9 are evenly arranged on the mounting plate 8. The mounting heads 9 are connected to the handle of the scraper 4. A reinforcing plate 10 is installed on the scraper 4, horizontally positioned on the upper part of the scraper 4. A baffle 11 is installed on the scraper 4, vertically positioned and connected to the reinforcing plate 10. The reinforcing plate 10 on the scraper 4 enhances the structural strength of the scraper 4 and prevents deformation. The baffle 11 on the scraper 4 reduces the amount of material entering the mounting plate 8 during movement.

[0031] The lower part of the main shaft 7 is connected to the reducer 12, which is located below the heating tank 2 and is connected to the motor 13.

[0032] A discharge pipe 14 is provided at the lower part of the heating tank 2, which is connected to the discharge port 5 of the lower heating plate 3. A feed chute 15 is provided at the upper part of the heating tank 2, which is offset from the discharge port 5 of the upper heating plate 3 and is located below the conveyor belt 1. The heated material falls into the discharge pipe 14 and is discharged from the discharge pipe 14 to enter the next process, realizing RAP oilstone separation.

[0033] A flue pipe 16 is installed on the heating tank 2, and the flue pipe 16 is connected to a flue gas treatment device. The flue gas treatment device collects and treats the flue gas generated by heating asphalt.

[0034] Working principle: The conveyor belt 1 transports the material to the heating plate 3 of the heating tank 2. The main shaft 7 drives the mounting plate 8 and the scraper 4 to rotate. The scraper 4 pushes the material to rotate on the heating plate 3. The material falls from the discharge port 5 into the next layer of heating plate 3 for further heating. The material is heated by multiple layers of heating plates 3.
