Description

Technical Field

[0001] This utility model belongs to the field of asphalt processing technology, specifically relating to a mixer for producing modified asphalt concrete. Background Technology

[0002] Modified asphalt concrete is often used in routine road construction. During the production of modified asphalt concrete, a mixer is usually used to mix the asphalt. Existing mixers generate a large amount of harmful fumes during the heating and mixing process of the asphalt. If these fumes are directly emitted, they will not only pollute the environment but also harm the health of workers.

[0003] The prior art CN208990600U discloses a mixing device for the production of modified asphalt. During the heating and mixing process of modified asphalt, the mixing device uses an air pump to draw the harmful fumes generated by heating into a flue gas purification box, thereby purifying the harmful fumes before discharge, so as to avoid direct emission of waste gas that would pollute the environment and harm the health of workers.

[0004] However, the aforementioned mixing device cannot scrape off the high-viscosity modified asphalt adhering to its inner wall during use. As a result, the high-viscosity modified asphalt adhering to the inner wall of the mixer is difficult to clean after it solidifies, which will affect the subsequent use of the mixing device. Utility Model Content

[0005] The purpose of this utility model is to provide a mixer for the production of modified asphalt concrete, which aims to solve the technical problem that existing mixing devices cannot scrape off the high-viscosity modified asphalt adhering to their inner walls during use, making it difficult to clean the high-viscosity modified asphalt adhering to the inner walls of the mixer after it solidifies, thus affecting the subsequent use of the mixing device.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a mixer for producing modified asphalt concrete, including a mixing tank, a feed inlet, a support base, a drive mechanism, a mixing rod, mixing blades, a scraper, and a discharge pipe. The feed inlet is connected to the mixing tank and located on the mixing tank. The support base is disposed on the mixing tank. The drive mechanism is located between the support base and the mixing tank and is used to drive the mixing rod to move up and down or rotate. The mixing rod is movably disposed inside the mixing tank, passes through the mixing tank, and extends outside the mixing tank. A plurality of mixing blades are evenly disposed outside the mixing rod. Each mixing blade is provided with a scraper, and both the mixing blades and the scraper are located inside the mixing tank. The discharge pipe is connected to the mixing tank and located outside the mixing tank.

[0008] The driving mechanism includes a driving part, a driving plate, and a moving part. The driving part is disposed below the support base. The driving plate is connected to the output end of the driving part and rotatably connected to the stirring rod, and is located between the driving part and the stirring rod. The moving part is used to drive the stirring rod to rotate inside the mixing tank.

[0009] The moving component includes a rotating part and a transmission component. The rotating part is disposed below the drive plate, and the transmission component is used to transmit the rotational power of the rotating part to the stirring rod.

[0010] The transmission component includes a first gear and a second gear. The first gear is connected to the output shaft of the rotating part and is located outside the rotating part. The second gear meshes with the first gear and is disposed outside the stirring rod.

[0011] The modified asphalt concrete production mixer also includes a maintenance plate, which is detachably connected to the mixing tank and located in the slot of the mixing tank.

[0012] This utility model discloses a mixer for producing modified asphalt concrete. The feed inlet is connected to and located on the mixing tank. A support base is disposed on the mixing tank. A drive mechanism is located between the support base and the mixing tank, used to drive the mixing rod to move up and down or rotate. The mixing rod is movably disposed inside the mixing tank, penetrates the mixing tank, and extends outside the mixing tank. Several mixing blades are evenly arranged on the outside of the mixing rod. Each mixing blade is equipped with a scraper, and both the mixing blades and the scraper are located inside the mixing tank. A discharge pipe is connected to and located outside the mixing tank. After the raw material is discharged, the scraper rotates and moves up and down within the mixing tank, thereby scraping off the residual raw material on the inner wall of the mixing tank and finally discharging it through the discharge pipe. This avoids the high-viscosity modified asphalt adhering to the inner wall of the mixer, which, after solidification, is difficult to clean and will ultimately affect the subsequent use of the mixing device.

Detailed Implementation

[0018] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] First Embodiment

[0020] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the mixer for producing modified asphalt concrete according to the first embodiment of this utility model. Figure 2 This is a cross-sectional schematic diagram along the first gear 112 of the mixer for producing modified asphalt concrete according to the first embodiment of this utility model. Figure 3 This is a cross-sectional view of the mixer for producing modified asphalt concrete according to the second embodiment of this utility model, along the feed inlet 102.

[0021] This utility model provides a mixer for producing modified asphalt concrete, comprising a mixing tank 101, a feed inlet 102, a support base 103, a drive mechanism, a mixing rod 104, mixing blades 105, a scraper 106, a discharge pipe 107, and a maintenance plate 108. The drive mechanism includes a drive unit 109, a drive plate 110, and a moving component. The moving component includes a rotating part 111 and a transmission component, which includes a first gear 112 and a second gear 113. This solution solves the problem that the aforementioned mixing device cannot scrape off the high-viscosity modified asphalt adhering to its inner wall during use, making it difficult to clean after the high-viscosity modified asphalt solidifies, thus affecting the subsequent use of the mixing device. It is understood that the aforementioned solution can be used in the production of modified asphalt concrete.

[0022] In this embodiment, the raw materials for preparing modified asphalt concrete are fed into the mixing tank 101 through the feed inlet 102. The driving mechanism then drives the stirring rod 104 to rotate and move up and down along its own axis within the mixing tank 101. This causes the stirring blades 105 to rotate and move up and down along the axis of the stirring rod 104 within the mixing tank 101. This, in turn, causes the scraper 106 to rotate and move up and down along the axis of the stirring rod 104 within the mixing tank 101. The rotation and movement of the stirring blades 105 within the mixing tank 101 along the axis of the stirring rod 104 allow the stirring blades 105 to mix and stir the raw materials within the mixing tank 101. After mixing, The material is discharged from the discharge pipe 107 to the outside of the mixing tank 101. The scraper 106 rotates and moves up and down along the axis of the mixing rod 104 inside the mixing tank 101, so that after the material is discharged, the scraper 106 can scrape off the material remaining on the inner wall of the mixing tank 101 and finally discharge it from the discharge pipe 107. This avoids the problem that the high viscosity modified asphalt adhering to the inner wall of the mixer is difficult to clean after solidification, which will eventually affect the subsequent use of the mixing device. This solves the technical problem that existing mixing devices cannot scrape off the high viscosity modified asphalt adhering to their inner walls during use, which makes it difficult to clean the high viscosity modified asphalt adhering to the inner wall of the mixer after solidification, thus affecting the subsequent use of the mixing device.

[0023] The feed inlet 102 is connected to and located on the mixing tank 101. The support base 103 is mounted on the mixing tank 101. The drive mechanism is located between the support base 103 and the mixing tank 101, and is used to drive the stirring rod 104 to move up and down or rotate. The stirring rod 104 is movably disposed inside the mixing tank 101, passes through the mixing tank 101, and extends outside the mixing tank 101. A plurality of stirring blades 105 are evenly arranged outside the stirring rod 104. Each stirring blade 105 is equipped with a scraper 106, and both the stirring blades 105 and the scraper 106 are located inside the mixing tank 101. The discharge pipe 107 is connected to and located outside the mixing tank 101. A valve 115 is provided on the side of the discharge pipe 107 away from the mixing tank 101, and the valve 115 is used to control the passage of the discharge pipe 107. The opening or closing of the mixing tank allows the raw materials entering the mixing tank 101 from the inlet 102 to be stirred and mixed within the tank. After stirring and mixing, the raw materials are discharged from the mixing tank 101 through the discharge pipe 107. The stirring rod 104 can move up and down or rotate along its own axis within the mixing tank 101, driving the stirring blades 105 to move up and down or rotate along the axis of the stirring rod 104 within the mixing tank 101. This, in turn, drives the scraper 106 to move up and down or rotate along the axis of the stirring rod 104 within the mixing tank 101. A heating plate 114 is provided at the bottom of the mixing tank 101. The heating plate 114 can heat the raw materials during the stirring and mixing process within the mixing tank 101, making the raw materials in the mixing tank 101 more fluid.

[0024] Secondly, the drive unit 109 is disposed below the support base 103. The drive plate 110 is connected to the output end of the drive unit 109 and rotatably connected to the stirring rod 104, and is located between the drive unit 109 and the stirring rod 104. The moving member is used to drive the stirring rod 104 to rotate inside the mixing tank 101. The output end of the drive unit 109 is connected to the drive plate 110 and drives the drive plate 110 to move up and down below the support base 103, thereby driving the moving member to move up and down above the mixing tank 101, and further driving the stirring rod 104 to move up and down above the mixing tank 101.

[0025] Furthermore, the rotating part 111 is disposed below the drive plate 110, and the transmission member is used to transmit the rotational power of the rotating part 111 to the stirring rod 104.

[0026] Furthermore, the first gear 112 is connected to the output shaft of the rotating part 111 and is located outside the rotating part 111. The second gear 113 meshes with the first gear 112 and is disposed outside the stirring rod 104. Both the first gear 112 and the second gear 113 are bevel gears, and the first gear 112 and the second gear 113 are arranged perpendicularly. The output shaft of the rotating part 111 is coaxially arranged with the first gear 112, and the second gear 113 is coaxially arranged with the stirring rod 104. The output shaft of the rotating part 111 is connected to the first gear 112 and drives the first gear 112 to rotate along its own axis. Since the second gear 113 meshes with the first gear 112, the rotation of the first gear 112 along its own axis can drive the second gear 113 to rotate along its own axis, thereby driving the stirring rod 104 to rotate along its own axis inside the stirring tank 101.

[0027] Finally, the maintenance plate 108 is detached from the mixing tank 101 and located in the slot of the mixing tank 101. The maintenance plate 108 can be installed or removed in the slot of the mixing tank 101, thereby opening the slot of the mixing tank 101 and exposing the internal space of the mixing tank 101. This allows the scraper 106 to be removed and replaced with a new scraper 106 after it has been worn down during long-term use.

[0028] When using this invention, the raw materials for preparing modified asphalt concrete are fed into the mixing tank 101 through the feed inlet 102. The rotating part 111 is then activated, causing the power output from the output shaft of the rotating part 111 to drive the first gear 112 to rotate along its own axis. Since the second gear 113 meshes with the first gear 112, the rotation of the first gear 112 along its own axis drives the second gear 113 to rotate along its own axis, thereby driving the stirring rod 104 to rotate along its own axis within the mixing tank 101. This, in turn, drives the stirring blade 105 to rotate along the axis of the stirring rod 104 within the mixing tank 101. The drive unit 10 is then activated. 9. The power output from the output end of the drive unit 109 drives the drive plate 110 to move up and down below the support base 103, thereby driving the stirring rod 104 to move up and down above the mixing tank 101, and in turn driving the stirring blade 105 to move up and down inside the mixing tank 101. Combined with the rotation of the stirring blade 105 along the axis of the stirring rod 104 inside the mixing tank 101, the stirring blade 105 can stir and mix the raw materials in the mixing tank 101. During the stirring and mixing process, the heating plate 114 can heat the raw materials in the mixing tank 101, making the raw materials in the mixing tank 101 more fluid.

[0029] After the raw materials are mixed, the discharge pipe 107 is opened through the valve 115 to discharge the raw materials from the mixing tank 101 to the outside of the mixing tank 101. After the raw materials are discharged, the mixing blades 105 continue to rotate and move up and down along the axis of the mixing rod 104 inside the mixing tank 101, driving the scraper 106 to rotate and move up and down along the axis of the mixing rod 104 inside the mixing tank 101. This allows the scraper 106 to scrape off the raw materials remaining on the inner wall of the mixing tank 101 and finally discharge them from the discharge pipe 107. This avoids the problem that the high-viscosity modified asphalt adhering to the inner wall of the mixer is difficult to clean after solidification, which would eventually affect the subsequent use of the mixing device. This solves the technical problem that existing mixing devices cannot scrape off the high-viscosity modified asphalt adhering to their inner walls during use, making it difficult to clean the high-viscosity modified asphalt adhering to the inner wall of the mixer after solidification, thus affecting the subsequent use of the mixing device.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
