Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of aggregate processing, in particular to a device for preparing recycled water-stable aggregate from demolition waste and road waste. BACKGROUND
[0002] Water-stable recycled aggregate is a kind of recycled aggregate made from waste highway pavement (including asphalt concrete and cement concrete) by crushing, screening, adding calcium-based curing agent and adding additives such as fly ash. Compared with the original material, they have higher stability, better durability and lower cost.
[0003] The raw material of recycled aggregate often contains various impurities. If these impurities are not removed during the crushing process, they will seriously damage the strength, stability and durability of the water-stable base. Among them, the asphalt film on the surface of the waste asphalt concrete is the most difficult impurity to handle. The existing technology usually uses a three-stage process of "heating and softening, mechanical stripping, and water washing" to handle the asphalt film. First, the crushed coarse material is added to a drum heater to soften the hard and brittle asphalt film at room temperature into a viscous state. Then, it is sent to a double-shaft rubbing machine for rubbing and stripping to remove the viscous asphalt film from the surface of the aggregate. Finally, the high-pressure water washing device is used to flush the residual asphalt film on the surface of the aggregate. During the transfer process between the heating machine, rubbing machine and high-pressure water washing device, the aggregate needs to pass through intermediate links such as conveyer belts or chutes, and the transfer time is usually 10-30 seconds. During this period, the viscous asphalt film quickly cools down (the temperature drop can be up to 20-40℃) due to contact with air, and it is easy to re-solidify and re-bond to the surface of the aggregate or the inner wall of the equipment, making it difficult to completely remove the residual asphalt film by subsequent water washing, resulting in a residual asphalt rate that does not meet the standard and becoming a key bottleneck that restricts the quality of the aggregate.

For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0024] Please refer to Figures 1 to 7 The device for preparing recycled water-stable material by using demolition garbage and road garbage provided by the present application comprises an outer sleeve 1 and a series processing assembly 2. The series processing assembly 2 is arranged in the outer sleeve 1. The series processing assembly 2 comprises an inner sleeve 201 arranged in the outer sleeve 1. A partition plate 202 is fixedly arranged in the middle of the inner sleeve 201 in the radial direction. An axial flow fan 203 is arranged in parallel with the axis of the inner sleeve 201 at the top end of the partition plate 202. A hot air pipe 204 is connected to the air outlet of the axial flow fan 203. A heating section 205 is arranged at the rear end of the inner sleeve 201. The heating section 205 is wrapped with a heating block 206. The outer circle of the heating block 206 is arranged with radiation fins 207 in an array. A stripping section 208 is arranged at the front end of the inner sleeve 201. Hollow holes 209 are evenly arranged on the outer circle of the stripping section 208. Ring-shaped spray pipes 210 are arranged on the outer circle of the stripping section 208 in an equal interval in the axial direction. A drying section 211 is connected to the end of the inner sleeve 201. A semicircular partition plate 212 is fixedly arranged at the top end of the inlet of the drying section 211. The top end of the drying section 211 is connected to the outlet end of the hot air pipe 204. The inner sleeve 201 comprises a three-section structure from the rear to the front, which comprises the heating section 205, the stripping section 208 and the drying section 211. The partition plate 202 fixedly arranged in the middle of the inner sleeve 201 separates the heating section 205 and the stripping section 208. The semicircular partition plate 212 fixedly arranged at the top end of the inlet of the drying section 211 separates the stripping section 208 and the outlet end of the hot air pipe 204.
[0025] The specific operation is as follows: after the raw materials of the recycled aggregate are pre-crushed, the small particles and fine materials are removed through the air separation screen, and the remaining large particles and coarse materials larger than the size of the hollow hole 209 are sent into the feeding pipe 4 through the hopper 5. Under the action of the screw auger 303 at the rear end of the main shaft 301, the coarse materials enter the heating section 205 at the rear end of the inner sleeve 201, and under the action of the heating block 206 wrapped outside the heating section 205, the hard and brittle asphalt film on the surface of the coarse materials is heated and softened into a viscous flow state. At this time, under the action of the four-petal turning paddle 304 in the middle of the main shaft 301, the mechanical peeling of the asphalt film is realized by using the collision and friction between the coarse material particles combined with heating and softening. Then, the coarse material particles enter the peeling section 208 at the front end of the inner sleeve 201, and the asphalt film on the surface of the heated aggregate is immediately separated by the water washing method. The peeled asphalt particles follow the water flow and flow into the water storage cavity 902 in the support seat 901 through the hollow hole 209. The water inlet of the water pump 905 fixed at the bottom end of the side surface of the support seat 901 filters out impurities through the filter screen, and then the water flow in the water storage cavity 902 is pumped out through the hot water coil 906 connected to the water outlet of the water pump 905. The hot water coil 906 is spirally threaded through the inside of the heating block 206 and connected to the annular spray pipe 210 at the rear end, so that the water flow is preheated during the spiral passage through the heating block 206. In this way, the annular spray pipe 210 installed radially outside the peeling section 208 sprays hot water, which can effectively prevent the re-solidification and secondary bonding of the asphalt film while assisting in the peeling of the asphalt film. The coarse materials in this application complete the process of "heating and softening → particle collision and peeling → hot water spraying and separation" in the same inner sleeve 201, without the need for external transfer links such as conveyors and chutes, thereby avoiding the process of exposing the aggregate to air cooling and ensuring that the asphalt is always in a viscous flow state until it is washed away by water. Moreover, the hot water preheated by the heating block 206 matches the temperature of the heating section 205, and is sprayed out through the annular spray pipe 210. On the one hand, it can maintain the surface temperature of the aggregate to prevent the asphalt from re-solidifying due to temperature drop. On the other hand, the hot water has a better flushing ability than normal temperature water for the viscous asphalt, which can more efficiently remove the residual asphalt film on the surface and in the pores of the aggregate.
[0026] Please refer to Figures 2 to 5 The inner sleeve 201 is internally provided with a linkage energy supply assembly 3, which includes a main shaft 301 installed along the axis direction of the inner sleeve 201.

[0029] It can be understood that the application separates the heating section 205 and the stripping section 208 in front and back of the inner sleeve 201 by radially fixing the isolation plate 202 in the middle of the inner sleeve 201 and by the isolation plate 202, and the heating block 206 wrapped outside the heating section 205 realizes the preheating of aggregate and the heating of water flow in the internal spiral water coil 906, and at the same time, the radiation fins 207 installed outside the heating block 206 realize heat radiation into the structural gap between the heating section 205 and the outer sleeve 1, the shaft fan 203 at the top end of the isolation plate 202 transports the hot air radiated in the structural gap between the heating section 205 and the outer sleeve 1 to the drying section 211 at the end of the inner sleeve 201 through the hot air pipe 204, and the semi-circular partition plate 212 fixed at the top end at the entrance of the drying section 211 separates the stripping section 208 from the outlet of the hot air pipe 204, greatly blocks the mixing of moisture in the stripping section 208, maintains a low-humidity and high-wind-speed hot environment above the drying section 211, and the damp coarse material discharged from the stripping section 208 falls into the inside of the notch of the "L" shaped structure of the scoop 305, and cannot be directly discharged from the discharge port 6 at the bottom end of the drying section 211, but can only follow the rotation of the scoop 305 and enter the drying section 211 above and realize drying under the action of the hot air continuously output by the hot air pipe 204, and after completing one circle of circumferential movement, the dried coarse material can be discharged from the discharge port 6 at the bottom end of the drying section 211, and finally enters the inclined sieve plate 7, realizes step-by-step sieving of different particle size aggregates through multiple sieve plates, and the hot air circulation system constructed by the "radiation fins 207+shaft fan 203+hot air pipe 204" maximizes the use of the waste heat of the heating section 205 for aggregate drying, and through the combined design of the "L" shaped scoop 305 and the semi-circular partition plate 212, the problems of insufficient residence time of aggregate, incomplete drying and chaotic discharge in traditional drying equipment are solved, and forced drying and orderly discharge are realized.
[0030] Please refer to Figures 3 to 4 The motor 10 is fixedly installed at the bottom side end of the outer sleeve 1, the rotating end of the motor 10 is fixedly connected with the direct drive rod 11, the direct drive rod 11 is rotationally connected with the belt pulley 302 through the transmission member one 12, the root of the direct drive rod 11 is engaged with the steering gear set 13, and the steering gear set 13 is rotationally connected with the skimming plate 904 through the transmission member two 14.
[0031] The motor 10 is installed at the bottom side end of the outer sleeve 1. On the one hand, the direct drive rod 11 directly connected with the rotating end of the motor 10 is rotated and driven to the belt pulley 302 through the transmission member one 12, and then the co-axial spiral auger 303, the turning paddle 304 and the skimmer 305 on the main shaft 301 are rotated and operated to realize the corresponding functions. On the other hand, the steering gear set 13 at the root of the direct drive rod 11 is rotated and driven to the skimming plate 904 through the transmission member two 14, and then the skimming plate 904 located at the opening at the side end of the water storage cavity 902 is rotated to realize the skimming of the asphalt floating scum, and the sewage containing dust and floating scum is discharged through the overflow weir 903, so as to reduce the filtering pressure of the filter screen at the water inlet of the water pump 905. Through the double transmission chain design of the direct drive rod 11 and the main shaft 301, and the steering gear set 13 and the skimming plate 904, the operation rhythm of the aggregate treatment and the skimming and cleaning of the sewage is highly coordinated, the system disorder caused by the different functions is avoided, the energy consumption is optimized, and the operation cost is reduced.
[0032] In summary, in the use of the device, the recycled aggregate raw material is first crushed and then the small particles and fine materials are removed through the air separation screen, and the remaining large particles larger than the size of the hollow hole 209 are sent into the feeding pipe 4 through the hopper 5, and under the action of the screw auger 303 at the rear end of the main shaft 301, the coarse material enters the heating section 205 at the rear end of the inner sleeve 201, and under the action of the heating block 206 wrapped outside the heating section 205, the hard and brittle asphalt film on the surface of the coarse material is heated and softened into a viscous flow state. At this time, under the action of the four-petal turning paddle 304 in the middle of the main shaft 301, the mechanical peeling of the asphalt film is realized by using the collision and friction between the coarse material particles combined with heating and softening. Then the coarse material particles enter the peeling section 208 at the front end of the inner sleeve 201, and the asphalt film on the surface of the heated aggregate is immediately separated by the water washing method. The peeled asphalt particles follow the water flow through the hollow hole 209 and flow into the water storage cavity 902 in the support seat 901. The water inlet of the water pump 905 fixed at the bottom end of the side surface of the support seat 901 filters out impurities through the filter screen, and then the water flow in the water storage cavity 902 is pumped out through the hot water coil 906 connected to the outlet of the water pump 905. The hot water coil 906 spirally passes through the inside of the heating block 206 and is connected to the annular spray pipe 210 at the rear end, so that the water flow is preheated during the spiral passage through the heating block 206. In this way, the annular spray pipe 210 installed radially outside the peeling section 208 sprays hot water, which can effectively prevent the re-solidification and secondary bonding of the asphalt film while assisting in the peeling of the asphalt film. The coarse material in this application completes the processes of "heating and softening → particle collision and peeling → hot water spraying and separation" in the same inner sleeve 201, without the need for external transfer links such as conveyors and chutes, avoiding the process of exposing the aggregate to air cooling, ensuring that the asphalt is always in a viscous flow state until it is washed away by water, and the hot water preheated by the heating block 206 matches the temperature of the heating section 205, which is sprayed out through the annular spray pipe 210. On the one hand, it can maintain the surface temperature of the aggregate to prevent the asphalt from re-solidifying due to temperature drop. On the other hand, hot water has better flushing ability than normal temperature water for viscous asphalt, which can more efficiently remove the residual asphalt film on the surface and in the pores of the aggregate; Secondly, the inner sleeve 201 is radially fixed with the isolation plate 202 in the middle part, and the heating section 205 and the stripping section 208 before and after the inner sleeve 201 are isolated by the isolation plate 202. The heating block 206 wrapped outside the heating section 205 realizes preheating of aggregate and heating of water flow in the hot water coil 906, and at the same time, heat radiation is realized in the structural gap between the heating section 205 and the outer sleeve 1 through the radiation fins 207 installed outside the heating block 206. The shaft flow fan 203 at the top end of the isolation plate 202 transports the hot air radiated in the structural gap between the heating section 205 and the outer sleeve 1 to the drying section 211 at the end of the inner sleeve 201 through the hot air pipe 204, and the stripping section 208 is isolated from the outlet of the hot air pipe 204 by the semicircular partition plate 212 fixed at the top end of the entrance of the drying section 211, which greatly blocks the mixing of moisture in the stripping section 208, so that a low-humidity and high-wind-speed hot environment is maintained above the drying section 211. The damp aggregate discharged from the stripping section 208 falls into the inside of the notch of the "L"-shaped structure of the scoop 305, and cannot be directly discharged from the discharge port 6 at the bottom end of the drying section 211, but can only rotate with the scoop 305 and enter the drying section 211 above to be dried under the action of the hot air continuously output by the hot air pipe 204. After one circle of circumferential movement, the dried aggregate can be discharged from the discharge port 6 at the bottom end of the drying section 211 and finally enter the inclined sieve plate 7, and different particle size aggregates are gradually separated by multiple sieve plates. The hot air circulation system composed of the "radiation fins 207 + shaft flow fan 203 + hot air pipe 204" maximizes the use of the waste heat of the heating section 205 for aggregate drying, and the combination of the "L"-shaped scoop 305 and the semicircular partition plate 212 solves the problems of insufficient residence time of aggregate, incomplete drying and chaotic discharge in traditional drying equipment, and realizes forced drying and orderly discharge. Finally, the motor 10 is installed at the bottom side end of the outer sleeve 1. On the one hand, the direct drive rod 11 directly connected to the rotating end of the motor 10 rotates the belt pulley 302 through the transmission member one 12, and then drives the co-axial spiral auger 303, the turning paddle 304 and the scoop 305 on the main shaft 301 to rotate and work to realize the corresponding functions. On the other hand, the steering gear set 13 at the root of the direct drive rod 11 rotates the skimming plate 904 through the transmission member two 14, and then drives the skimming plate 904 at the side end opening of the water storage cavity 902 to rotate to skim the asphalt float, and the sewage containing dust and float is discharged through the overflow weir 903, reducing the filtering pressure of the filter screen at the water inlet of the water pump 905. The double transmission chain design of the direct drive rod 11 and the main shaft 301, and the steering gear set 13 and the skimming plate 904 makes the operation rhythm of aggregate treatment and skimming and cleaning highly coordinated, avoids system disorder caused by different functions, optimizes energy consumption, and reduces operation cost.
