Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of asphalt heat regeneration, and particularly relates to an asphalt heat regeneration anti-sticking device. BACKGROUND

[0002] The performance of asphalt will degrade after a period of use, and the original asphalt needs to be conveniently recycled, mixed with new asphalt raw materials after crushing, and then used again, thereby effectively improving the utilization efficiency of materials and avoiding waste. When paving asphalt, the asphalt raw materials need to be heated to avoid solidification and adhesion, which affects subsequent pouring and paving operations.

[0003] However, in actual use, when the asphalt is discharged to the outside, the flowability of the asphalt often becomes poor due to a decrease in temperature. In addition, when the regenerated asphalt is applied, it is usually poured onto the road surface through the inclined conveying plate at the bottom of the stirring barrel. Because the conventional conveying device lacks a heating structure, once the asphalt sticks, it is easy to cause blockage, which affects pouring and use, and manual cleaning is required, which is very inconvenient. In addition, the asphalt paving operation needs to be stopped, and thus a device that can conveniently clean the asphalt conveying structure is needed. SUMMARY

[0004] The utility model aims at providing an asphalt heat regeneration anti-sticking device, which solves the problems of regenerated asphalt adhesion and fixation and inconvenient manual cleaning in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an asphalt heat regeneration anti-sticking device, comprising a stirring tank, a stirring rod and a conveying plate, wherein the stirring rod is arranged through the inside center of the stirring tank, the conveying plate is rotatably connected to the bottom of the stirring tank, the outer wall of the conveying plate is annularly provided with a rotating belt, one end of the bottom of the rotating belt is provided with a connecting rod, and the other end of the bottom of the rotating belt, away from the connecting rod, is provided with a cleaning roller.

[0006] The outer wall of the stirring rod is annularly provided with a plurality of stirring rods near the top, the outer wall of the stirring tank is fixedly connected with a rotating scraper near the bottom end of the stirring tank, and the bottom outer wall of the stirring rod is fixedly connected with a spiral blade.

[0007] The outer wall of the conveying plate is fixedly connected with a baffle on both sides, the outer wall of the end of the conveying plate, away from the connecting rod, is rotatably connected with an electric push rod at the top, and the top of the electric push rod is rotatably connected with the bottom of the stirring tank.

[0008] The outer wall of the connecting rod, near the bottom of the rotating belt, is fixedly connected with a scraper in an inclined manner, and the outer wall of the cleaning roller is in close contact with the bottom surface of the rotating belt.

[0009] Preferably, the bottom of the mixing tank is funnel-shaped, and a conveying pipe is fixedly connected to the bottom of the mixing tank. Both the conveying pipe and the outer wall of the mixing tank are equipped with electric heating modules. The inner wall of the conveying pipe corresponds to the outer wall of the spiral blade, and the outer wall of the rotating scraper corresponds to and fits against the inclined surface at the bottom of the inner wall of the mixing tank.

[0010] Preferably, the bottom of the mixing tank is equipped with connecting plates on both sides near the conveying plate. The bottom sidewall of the connecting plate is rotatably connected to the inside of the conveying plate through a rotating shaft. The bottom protruding end of the electric push rod is rotatably connected to one end of the baffle.

[0011] Preferably, drive rollers are rotatably connected to both ends of the conveyor plate, the outer wall of the drive roller is in contact with the inner end of the rotating belt, a drive motor is installed at one end of the outer wall of the drive roller, and a rotating motor is installed at the top of the stirring rod.

[0012] Preferably, the top end of the connecting rod is inclined away from the cleaning roller and fits against the surface of the rotating belt, and both ends of the connecting rod are equipped with torsion springs. The outer wall of the cleaning roller is surrounded by cleaning brushes, and one end of the cleaning roller is connected to a rotating motor.

[0013] Preferably, a lubricating brush is provided at the bottom end of the rotating belt away from the connecting rod, the outer wall of the lubricating brush is in contact with the rotating belt, and the outer wall of the lubricating brush is coated with lubricant.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The driving agitator rotates, thereby agitating the material inside the mixing tank to prevent sedimentation, stratification, or solidification. At the same time, the material can be effectively heated through the mixing tank and the external conveying pipe. When it is necessary to discharge asphalt to the bottom, the conveying pipe can be opened and the agitator rotated in the opposite direction, which will cause the spiral blades to rotate, thereby conveying the material to the bottom. It can also easily rotate the rotating scraper, so that the material on the inclined surface at the bottom of the mixing tank can be easily agitated and cleaned, preventing asphalt material from accumulating and sticking together.

[0016] 2. The drive roller rotates, causing the rotating belt to follow suit, which in turn drives and conveys the material. After conveying, the bottom of the rotating belt comes into contact with the scraper and scrapes it. The scraper can easily clean the material adhering to the surface of the rotating belt. At the same time, the cleaning roller can be restarted to rotate and clean the adhering material again. When the rotating belt rotates, it can come into contact with the lubricating brush, so that the surface of the rotating belt is covered with lubricant. This can effectively isolate the rotating belt from the asphalt material through the lubricant, further reducing adhesion and attachment. No manual cleaning is required, reducing labor intensity. At the same time, it can also achieve continuous production without interrupting the asphalt production and processing, ensuring production efficiency. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1-5The device for preventing sticking of hot asphalt recycling, as shown, includes a mixing tank 1, an agitator 2, and a conveying plate 3. The agitator 2 is inserted through the center of the mixing tank 1. The conveying plate 3 is rotatably connected to the bottom of the mixing tank 1. A rotating belt 4 is arranged around the outer wall of the conveying plate 3. A connecting rod 5 is provided at one bottom end of the rotating belt 4. A cleaning roller 6 is provided at the bottom end of the rotating belt 4 away from the connecting rod 5. Multiple agitator rods 202 are arranged around the outer wall of the agitator 2 near the top. A rotating scraper 201 is fixedly connected around the outer wall of the mixing tank 1 near the bottom end of the mixing tank 1. A spiral blade 203 is fixedly connected around the bottom outer wall of the agitator 2. Baffles 301 are fixedly connected to both sides of the outer wall of the conveying plate 3. An electric push rod 302 is rotatably connected to the top of the outer wall of the conveying plate 3 away from the connecting rod 5. The top of the electric push rod 302 is rotatably connected to the bottom of the mixing tank 1. A scraper 501 is fixedly connected at an angle to the outer wall of the connecting rod 5 near the bottom of the rotating belt 4. The outer wall of the cleaning roller 6 is in contact with the bottom surface of the rotating belt 4.

[0027] like Figure 1 , Figure 5 As shown, the bottom of the mixing tank 1 is funnel-shaped. A conveying pipe 101 is fixedly connected to the bottom of the mixing tank 1. Both the conveying pipe 101 and the outer wall of the mixing tank 1 are equipped with electric heating modules. The inner wall of the conveying pipe 101 corresponds to the outer wall of the spiral blade 203. The outer wall of the rotating scraper 201 corresponds to and fits against the inclined surface of the bottom of the inner wall of the mixing tank 1. Connecting plates 102 are installed on both sides of the bottom of the mixing tank 1 near the conveying plate 3. The bottom side wall of the connecting plate 102 is rotatably connected to the inside of the conveying plate 3 through a rotating shaft. The bottom protruding end of the electric push rod 302 is rotatably connected to one end of the baffle 301. The mixing tank 1 and the external conveying pipe 101 can effectively heat the material. When it is necessary to discharge asphalt to the bottom, the conveying pipe 101 can be opened and the stirring rod 2 can be rotated in the opposite direction, thereby causing the spiral blade 203 to rotate, thus realizing the material conveying to the bottom. At the same time, the rotating scraper 201 can be rotated easily, so that the material on the inclined surface at the bottom of the mixing tank 1 can be easily stirred and cleaned.

[0028] like Figure 3 , Figure 4 As shown, drive rollers 401 are rotatably connected to both ends of the conveyor plate 3. The outer wall of the drive roller 401 is in contact with the inner end of the rotating belt 4. A drive motor is installed on one end of the outer wall of the drive roller 401. A rotating motor is installed on the top of the stirring rod 2. When the drive roller 401 is started to rotate, the rotating belt 4 rotates accordingly, thereby driving the material to be conveyed. After the conveying is completed, the bottom of the rotating belt 4 is in contact with the scraper 501 and scrapes.

[0029] like Figure 3 , Figure 4As shown, the top end of the connecting rod 5 is inclined away from the cleaning roller 6 and fits against the surface of the rotating belt 4. Both ends of the connecting rod 5 are equipped with torsion springs. The outer wall of the cleaning roller 6 is surrounded by cleaning brushes. One end of the cleaning roller 6 is connected to a rotating motor. The bottom end of the rotating belt 4 away from the connecting rod 5 is equipped with a lubricating brush 601. The outer wall of the lubricating brush 601 fits against the rotating belt 4 and is coated with lubricant. The scraper 501 can easily clean the material adhering to the surface of the rotating belt 4. At the same time, the cleaning roller 6 can be restarted to rotate and clean the adhering material again. When the rotating belt 4 rotates, it can fit against the lubricating brush 601, so that the surface of the rotating belt 4 is covered with lubricant. This can effectively isolate the rotating belt 4 from the asphalt material through the lubricant, further reducing adhesion.

[0030] During use, the recycled asphalt after mixing can be easily poured into the mixing tank 1, and then the stirring rod 202 can be started to rotate, which will agitate the material inside the mixing tank 1, preventing the asphalt from settling, separating, or solidifying. At the same time, the material can be effectively heated through the mixing tank 1 and the external conveying pipe 101. When it is necessary to discharge asphalt to the bottom, the conveying pipe 101 can be opened and the stirring rod 2 can be rotated in the opposite direction, which will cause the spiral blade 203 to rotate, thereby realizing the material being conveyed to the bottom. At the same time, the rotating scraper 201 can also be rotated to easily agitate and clean the material on the inclined surface at the bottom of the mixing tank 1, preventing the asphalt material from accumulating, and allowing the material to move to one end of the bottom through the rotating belt 4.

[0031] In use, the drive roller 401 can be easily started to rotate, causing the rotating belt 4 to rotate accordingly, thereby driving and conveying the material. After conveying, the bottom of the rotating belt 4 comes into contact with the scraper 501 and scrapes it. The scraper 501 can easily clean the material adhering to the surface of the rotating belt 4. At the same time, the cleaning roller 6 can be started to rotate and clean the adhering material again. When the rotating belt 4 rotates, it can come into contact with the lubricating brush 601, so that the surface of the rotating belt 4 is covered with lubricating liquid. This can effectively isolate the rotating belt 4 from the asphalt material through the lubricating liquid, further reducing adhesion and re-adhesion. No manual cleaning is required, reducing labor intensity, and the asphalt production and processing operations can be interrupted.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
