Description

Technical Field

[0001] This utility model relates to the technical field of asphalt production and processing, specifically to a heating and mixing tank for recycling asphalt pavement repair waste. Background Technology

[0002] Asphalt pavement is widely used in road construction and maintenance. Over time and under traffic loads, asphalt pavement develops defects and requires repair. Traditional repair methods generate a large amount of waste, which, if not properly disposed of, pollutes the environment and wastes resources. Therefore, asphalt pavement repair waste recycling technology has emerged. In existing asphalt pavement repair waste recycling processes, the heating and mixing stage is crucial. Some heating and mixing tanks suffer from uneven heating, preventing the asphalt in the waste from fully melting and mixing, thus affecting the quality of the recycled mixture. Some mixing tanks have low mixing efficiency, making it difficult to meet the needs of large-scale production. Moreover, asphalt is highly viscous and easily adheres to the inner wall of the tank, making cleaning difficult, resulting in material waste and increased costs. Therefore, developing a high-efficiency, uniformly heated heating and mixing tank for asphalt pavement repair waste recycling that reduces material adhesion is of significant practical importance.

[0003] Application number CN202122375959.1 discloses an environmentally friendly asphalt mixing device for highway construction. In use, asphalt is first poured into the feed cylinder, then screened by a screening disc before entering the mixing tank. Large, unqualified particles and impurities are discharged through a waste discharge disc. The mixing motor then drives the mixing rod to rotate and mix the asphalt. Simultaneously, a heating coil is energized to heat the asphalt. Waste gas generated during mixing is drawn into a waste gas treatment cylinder by a vacuum pump through a vacuum pipe. The waste gas first passes through a... The filter layer filters the exhaust gas. When the exhaust gas enters the ionizer, the dust and tar in the exhaust gas are ionized under the action of electric charge. They move towards the charged metal wire and pipe wall, lose their charge, and fall to the bottom of the ionizer under the action of gravity and flow out. Then, the exhaust gas is discharged after the odor is adsorbed by the activated carbon adsorption layer. The asphalt after the mixing is completed is discharged through the discharge pipe. However, there is a shortcoming: when the device is in use, it is not able to perform internal screening of the material after the device has been mixed. This will affect the subsequent work.

[0028] The bracket assembly 1 includes a mounting bracket 101, a mounting bracket 2 102 fixedly mounted on one side of the mounting bracket 101, and a fixing suction cup 103 fixedly mounted diagonally at the bottom of the mounting bracket 101 and the mounting bracket 2 102. The mounting bracket 101 and the mounting bracket 2 102 in the bracket assembly 1 provide stable support for the entire equipment, and the fixing suction cup 103 at the bottom diagonally can be adsorbed on the ground to enhance the stability of the equipment.

[0029] The lifting and stirring braking assembly 2 includes a connecting base 201, a pneumatic pump 202 fixedly installed on the top of the connecting base 201, a lifting rod 203 installed on the top of the pneumatic pump 202, an extension plate 204 fixedly installed on the top of the lifting rod 203, the extension plate 204 is parallel to the mounting bracket 101 and extends towards the middle of the mounting bracket 101, a rotary motor 205 is fixedly installed on the top of the extension plate 204, and a rotating rod 207 is fixedly installed on the bottom of the rotary motor 205.

[0030] The rotating rod 207 passes through the middle of the sealing cover 206, and the stirring rod 208 is fixedly installed at one of the bottom corners of the rotating rod 207.

The sealing cover 206 is fixedly installed at the bottom of the extension plate 204 and in the lifting and stirring braking assembly 2. The pneumatic pump 202 drives the lifting rod 203 to lift and lower the extension plate 204, the rotary motor 205, the rotating rod 207 and other components. The rotary motor 205 drives the rotating rod 207 to rotate, thereby causing the stirring rod 208 to stir the waste and the cleaning scraper 209 to clean the inner wall of the heating tank assembly 3.

[0032] One end of the filter screen 406 is positioned lower than the transmission pipe 405 on the other side. The solid-liquid separation component 4 relies on the brake motor 402 to drive the spiral transmission device 404 via the transmission device 403 to transport waste material in the transmission pipe 405, and uses the filter screen 406 to achieve solid-liquid separation.

[0033] This asphalt pavement repair waste recycling and heating mixing tank uses a support assembly 1 as its foundation. A lifting and mixing braking assembly 2 is used to achieve the mixing and lifting of the waste. A heating storage tank assembly 3 heats and stores the waste, and a solid-liquid separation assembly 4 completes the solid-liquid separation of the waste. These components work together to recycle asphalt pavement repair waste. Mounting brackets 101 and 102 in the support assembly 1 provide stable support for the entire equipment. Diagonally opposite suction cups 103 at the bottom can adhere to the ground, enhancing the equipment's stability. In the lifting and mixing braking assembly 2, a pneumatic pump 202 drives a lifting rod 203, which in turn drives the extension plate 204, rotary motor 205, and rotating rod 207 to rise and fall. The rotary motor 205 drives the rotating rod 207 to rotate, thereby causing the mixing rod 208 to mix the waste and the cleaning scraper 209 to clean the inner wall of the heating storage tank assembly 3. In the heating tank assembly 3, the heating tank 302 heats the waste material, the shock absorber 303 reduces the vibration during the heating process, and the discharge telescopic plate 306 and the pneumatic telescopic rod 307 control the discharge. The solid-liquid separation component 4 relies on the brake motor 402 to drive the spiral conveyor 404 via the transmission device 403 to transport waste material in the transmission pipeline 405. Solid-liquid separation is achieved using the filter screen 406. In the working process, the equipment is moved to the work site and adhered to the ground by the fixed suction cups 103 at the bottom of the support component 1 to ensure equipment stability. The asphalt pavement repair waste is placed into the heating tank 302 of the heating tank component 3 in a suitable manner. The heating tank 302 is located inside the center of the installation tank 301 and is supported by the shock absorber 303 via the support plate 304. The pneumatic pump 202 in the lifting and mixing brake component 2 is started, which pushes the lifting rod 203 upward, driving the extension plate 204, the rotary motor 205, the rotating rod 207, and other components to rise until the rotating rod 207 passes through the sealing cover 206 and extends into the waste material in the heating tank 302. The sealing cover 206 is fixed to the bottom of the extension plate 204. The rotary motor 205 is started, and the rotary motor 205... The rotating rod 207 is driven to rotate, and the diagonally opposite stirring rod 208 at the bottom of the rotating rod 207 stirs the waste material to make it evenly mixed. At the same time, the cleaning scraper 209 at the other diagonal is set to intersect with the stirring rod 208, and cleans the inner wall of the heating tank 302 during rotation to prevent the waste material from sticking. The heating function of the heating tank 302 is turned on to heat the waste material to a temperature suitable for regeneration. The shock absorber 303 reduces the vibration generated during the heating process to ensure stable operation of the equipment. After the waste material is heated and stirred, the pneumatic telescopic rod 307 in the heating tank assembly 3 is activated. The pneumatic telescopic rod 307 pushes the discharge telescopic plate 306 to open the discharge port 305. The waste material in the heating tank 302 enters the transmission pipe 405 through the discharge port 305. The brake motor 402 in the solid-liquid separation assembly 4 is activated. The brake motor 402 drives the screw conveyor 404 to rotate in the transmission pipe 405 through the transmission device 403, and transports the waste material forward.Since one end of the filter screen 406 is lower than the other side of the transmission pipe 405, during the transmission process, liquid waste is separated and discharged through the filter screen 406, while solid waste continues to be transported in the transmission pipe 405 to a designated location for collection, thus completing the solid-liquid separation process.
