An asphalt binder preparation apparatus

Abstract

This invention relates to the field of asphalt adhesive technology and discloses an asphalt adhesive preparation device, including a tank, a top cover, a manhole, and a feeding port. The top cover is fixedly connected to the top of the tank, and the manhole is fixedly connected to the outer wall of the top cover. A first stirring plate is curved towards the stirring rod, and an elastic band made of silicone material is placed between the two plates. When the stirring rod is rotated by the driver, the reciprocating oscillation of the curved structure allows the viscous material around the first stirring plate to move towards the center of the tank, ensuring thorough mixing after contact with the second stirring plate. This avoids the problem of insufficient mixing of the viscous material near the inner wall of the tank. The elastic band not only seals the gap between the stirring plates to prevent material jamming but also adapts to the rotation of the first stirring plate, reducing leakage of viscous material from the gap between the two plates. This improves the effect of the first stirring plate pushing the viscous material towards the center of the tank, thereby enhancing the mixing effect of the viscous material.

Description

Technical Field

[0001] This invention relates to the field of asphalt adhesive technology, specifically to an asphalt adhesive preparation apparatus. Background Technology

[0002] Asphalt adhesive is a bonding material made primarily from asphalt, with modifiers, additives, and other components, prepared through a specific process. Leveraging the inherent viscosity of asphalt and the optimization of various modifiers and additives, it can effectively bond to different substrates (such as stone, steel, and concrete). It is widely used in road construction, building waterproofing, and industrial bonding, enhancing the integrity, waterproofing, and durability of structures.

[0003] Chinese invention patent CN117861501A discloses a composite asphalt adhesive preparation device and its preparation method. This invention sets up a mixing cylinder with a secondary box. The power component in the secondary box can drive the inner cylinder to rotate inside the mixing cylinder, so that it can rotate centrifugally after the mixed material is inside. Alternatively, the first motor on the top cover can drive the stirring shaft to rotate for mixing. Multiple mixing methods can be selected flexibly according to the mixed material and actual conditions. The set up filling component can put the material into the temporary storage cylinder when filling it, and then pump it into multiple branch filling pipes through a liquid pump, and inject it into the inner cylinder through a one-way valve. Injecting it directly into the mixed material from multiple directions can improve the mixing effect. Through testing and thermal desorption performance testing, the performance of the composite asphalt adhesive under high temperature environment is understood.

[0004] The existing technology also has the following problems: Existing technologies typically use a combination of centrifugal rotation of the inner cylinder and stirring by a stirring shaft, which makes it difficult to fully mix high-viscosity asphalt and modifiers. This easily creates a mixing isolation zone inside the tank, leading to material agglomeration and stratification, preventing deep penetration and fusion of the components. Furthermore, the fixed stirring method easily creates mixing blind spots. High-viscosity materials easily adhere to the inner wall of the tank, resulting in residue, which wastes materials, affects the quality of the next batch of products, and is difficult to clean, increasing operating costs. In addition, relying solely on a single mechanical stirring mode makes it difficult to break up the mixing isolation zone of the material flow field. For modifiers with high toughness and difficulty in dispersion, the dispersion effect is poor, resulting in insufficient uniformity and bonding strength stability of the finished product.

[0005] Therefore, an apparatus for preparing asphalt adhesive is proposed. Summary of the Invention

[0011] Preferably, the adjusting mechanism further includes a gas supply valve fixedly connected to the top of the top cover, and the gas supply valve extends downward through the top cover into the inner cavity of the tank. The bottom end of the gas supply valve is fixedly connected to a guide valve.

The driving telescopic sleeve is slidably connected to the outer wall of the stirring rod.

[0018] Preferably, the fixing plate is a bent rod-shaped structure.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The mixing plate 1 is curved towards the mixing rod, and with the elastic band made of silicone between the two plates, when the driver drives the mixing rod to rotate, the arc structure swings back and forth, which allows the sticky material around the mixing plate 1 206 to move towards the middle of the tank. This ensures that the sticky material comes into contact with the mixing plate 2 and is thoroughly mixed, avoiding the problem of insufficient mixing of sticky material near the inner wall of the tank. The elastic band can not only seal the gap between the mixing plates to prevent material from getting stuck, but also bend adaptively with the rotation of the mixing plate 1, reducing the leakage of sticky material from the gap between the mixing plates 1. This improves the effect of the mixing plate 1 in pushing the sticky material towards the middle of the tank, thereby improving the mixing effect of the sticky material. At the same time, the scrapers at both ends of the connecting plate are in contact with the inner wall of the tank. When the connecting plate rotates, they can scrape off the sticky material attached to the tank wall, which reduces material waste and prevents residual material from affecting the subsequent mixing effect, indirectly ensuring the uniformity of mixing.

[0021] 2. The adjustment mechanism uses a drive telescopic sleeve to slide adjustment blocks one and two, causing the adjustment rod to rotate in conjunction with hinged plate two and fixed plate two. This expands the mixing coverage area of ​​mixing plate two. Combined with the rotation of the mixing rod, this achieves full-area mixing of materials within the tank without dead zones. Simultaneously, it drives the nozzles to move synchronously, creating a synergistic effect of mechanical mixing and gas jets through the gas nozzles. The shearing action of the side nozzles disrupts the mixing isolation zone of the flow field, while the rear nozzles enhance liquid turbulence, effectively solving the problems of agglomeration and stratification of high-viscosity asphalt and modifiers. Furthermore, the overall temperature control system and the staged feeding design of the feeding structure ensure full penetration and fusion of all components, significantly improving the uniformity and bonding strength of the finished product and reducing performance differences between batches.

[0022] 3. The stirring plate is connected to the connecting sleeve plate via a hinge block and a hinge rod, allowing the connecting sleeve plate to slide along the connecting plate. This causes the stirring plate to rotate around the sleeve axis, allowing the viscous material on one side of the tank's inner wall to move towards the center of the tank. In addition, the adjustment mechanism drives the telescopic sleeve plate to slide the adjustment blocks one and two along the stirring rod. The adjustment rod and the hinge plate two drive the fixed plate to rotate around the shaft axis, thereby changing the stirring posture and coverage of the stirring plate two. Combined with the rotational movement of the stirring rod, targeted stirring of different areas in the upper, middle, and lower parts of the tank can be achieved, avoiding insufficient stirring in certain areas.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0037] Please see Figures 1 to 11 An embodiment of the present invention provides an asphalt adhesive preparation device, comprising a tank 101, a top cover 102, a manhole 103, and a feeding port 104. The top cover 102 is fixedly connected to the top of the tank 101. The manhole 103 is fixedly installed on one end of the outer wall of the top cover 102 and communicates with the tank 101. The feeding port 104 is fixedly installed on the other end of the outer wall of the top cover 102 and communicates with the tank 101. A partial stirring mechanism 200 is provided inside the tank 101, and a partial adjusting mechanism 300 is provided inside the tank 101.

[0038] The stirring mechanism 200 includes a connecting plate 203, a scraper 204, a sleeve 205, a stirring plate 206, and an elastic band 207. The connecting plate 203 is disposed inside the tank 101. The scraper 204 is symmetrically fixedly connected to both ends of the connecting plate 203 and fits against the inner wall of the tank 101. The sleeve 205 is symmetrically fixedly connected to the outer wall of the top of the connecting plate 203. The stirring plate 206 is rotatably connected to the outer wall of the sleeve 205. The elastic band 207 is symmetrically fixedly connected between the two stirring plates 206. The elastic band 207 is made of silicone.

[0039] The adjustment mechanism 300 includes a drive telescopic sleeve 305, an adjustment block 307, an adjustment rod 310, a hinge plate 311, and a fixing plate 312. The drive telescopic sleeve 305 is disposed inside the tank 101. The telescopic end of the drive telescopic sleeve 305 slides on the outer wall of the stirring rod 202. The adjustment block 307 is fixedly connected to the telescopic end of the drive telescopic sleeve 305. The adjustment rod 310 is symmetrically rotatably connected to the outer wall of the adjustment block 307. The hinge plate 311 is fixedly connected to the outer wall of the adjustment rod 310. The fixing plate 312 is rotatably connected to the outer wall of the bottom end of the hinge plate 311. The hinge plate 311 is inclined about the side away from the adjustment block 307 with the adjustment rod 310 as the axis. The fixing plate 312 is a bent rod structure.

[0040] It should be noted that the feeding port 104 is fixedly connected to the outer wall of the top of the top cover 102, and the feeding port 104 is connected to the interior of the top cover 102.

[0041] The driver 201-1 operates in a rotating state, and the driver telescopic sleeve 305 operates in an extending and retracting state. Both the driver telescopic sleeve 305 and the driver 201-1 are equipped with receiving control circuits, and the receiving control circuits are connected to the external control panel via radio signals. This allows the external control panel to transmit commands to the receiving control circuits to control the power supply between the driver 201-1 and the power supply 201, and also allows the external control panel to transmit commands to the receiving control circuits to control the power supply between the driver telescopic sleeve 305 and the driver 201-1.

[0042] Furthermore, the stirring mechanism 200 also includes a power supply 201 fixedly connected to the top of the top cover 102. The power supply 201 is connected to an external power source via a wire. A driver 201-1 is fixedly connected to the bottom of the power supply 201. The power transmission end inside the power supply 201 is connected to the power supply device inside the driver 201-1 via a conductive wire. The power supply device inside the drive telescopic sleeve 305 is connected to the power supply device inside the driver 201-1 via a conductive wire. A stirring rod 202 is fixedly connected to the drive end of the driver 201-1. The connecting plate 203 is fixedly connected to the outer wall of the middle part of the stirring rod 202. The stirring plate 206 is in an arc shape bent towards one side of the stirring rod 202. The inner walls of the two stirring plates 206 are fixedly connected to the hinge block 208. The hinge rod 209 is rotatably connected inside the hinge block 208. The hinge rod 209 is rotatably connected to the linkage sleeve 210. The linkage sleeve 210 is symmetrically slidably connected to the outer wall of the connecting plate 203. The outer wall of the connecting plate 203 is symmetrically provided with grooves 211. The upper surface of the linkage sleeve 210 is fixedly connected to the hinge plate 212.

[0043] It should be noted that when the linkage plate 210 slides along the connecting plate 203, the hinge block 208 is pulled by the hinge rod 209, which can flexibly adjust the flip angle of the stirring plate 206, thereby improving the stirring effect on viscous materials. The elastic band 207 made of rubber can not only seal the gap between the two stirring plates 206 to prevent high-viscosity materials from getting stuck and remaining, but its elastic restoring force can also provide auxiliary support when the stirring plate 206 is reset, ensuring the stability of the stirring process. The groove 211 provides sliding space for the linkage rod 308, avoiding interference between the adjustment mechanism 300 and the stirring mechanism 200 when they move, and ensuring the coordinated operation of each component.

[0044] Furthermore, the regulating mechanism 300 also includes a gas supply valve 301 fixedly connected to the top of the top cover 102, and the gas supply valve 301 extends downward through the top cover 102 into the inner cavity of the tank body 101. The gas supply valve 301 is connected to an external gas supply device, and a guide valve 302 is fixedly connected to the bottom end of the gas supply valve 301. The bottom end of the gas supply valve 301 is fixedly connected to the rotating cavity of the guide valve 302. The guide valve 302 is composed of a fixed cavity at the top and a rotating cavity at the bottom, and is fixed... The cavity and the rotating cavity are connected, and a sealing gasket is provided at the connection. Symmetrical grooves 303 are formed on the outer wall of the stirring rod 202, and symmetrical mounting grooves 304 are formed on the outer wall of the stirring rod 202. The grooves 303 are located at the top of the mounting grooves 304. A drive telescopic sleeve 305 is slidably connected to the outer wall of the stirring rod 202. Slider blocks 306 are symmetrically fixed to the inner wall of the telescopic end of the drive telescopic sleeve 305. The sliders 306 slide inside the grooves 303 for adjustment. A connecting rod 308 is symmetrically fixedly connected to the outer wall of block 307. The end of hinge plate 212 away from connecting sleeve plate 210 is fixedly connected to the outer wall of connecting rod 308. Connecting rod 308 slides inside groove 211. Adjusting block 309 is fixedly connected to the bottom end of connecting rod 308. Both adjusting block 307 and adjusting block 309 slide on the outer wall of stirring rod 202. Adjusting rods 310 are symmetrically rotatably connected to the outer wall of adjusting block 309. Fixed plate 3... A shaft 313 is fixedly connected to the inner wall of 12. The shaft 313 is rotatably connected to the outer wall of the mounting groove 304. A stirring plate 314 is symmetrically fixedly connected to the outer wall of the shaft 313. A nozzle 315 is fixedly connected to the bottom end of the shaft 313. An air guide port 316 is fixedly connected to the bottom inner wall of the air guide valve 302. Both ends of the air guide port 316 are fixedly connected to a folded tube 317. A folded tube 318 is fixedly connected between the two nozzles 315 in the vertical direction.

[0045] It should be noted that: since the rotating cavity at the bottom of the gas supply valve 301 and the gas guide valve 302 is fixedly connected, the stirring rod 202 cannot drive the gas supply valve 301 to rotate synchronously during the rotation of the gas guide valve 302, thus avoiding the problem of jamming.

[0046] Since the first folded tube 317 is vertically positioned between the air inlet 316 and the nozzle 315 inside the tank 101, and the second folded tube 318 is vertically positioned between the two nozzles 315 on the same vertical plane, and the connecting plate 203 rotates synchronously with the stirring rod 202, the connecting plate 203 rotates synchronously with the second folded tube 318 and the first folded tube 317, and the two stirring plates 314 on the synchronous vertical plane rotate synchronously to the side away from the stirring rod 202. Therefore, there is no phenomenon of the second folded tube 318, the first folded tube 317, or other structures being entangled or jammed.

[0047] The outer wall of the nozzle 315 has two symmetrical inclined surfaces, and the nozzles are evenly distributed on the circumference of the inclined surfaces.

[0048] The design of the slider 306 and the groove 303 limits the sliding trajectory of the drive telescopic sleeve 305, ensuring that the first adjusting block 307 and the second adjusting block 309 move smoothly along the axial direction of the stirring rod 202, avoiding adjustment failure caused by deviation. The inclined setting of the second hinge plate 311 can convert the axial movement into the flipping force of the fixed plate 312 under the drive of the adjusting rod 310, so as to realize the control of the stirring angle of the second stirring plate 314. The rotational connection between the shaft 313 and the mounting groove 304 provides stable support for the second stirring plate 314 and the nozzle 315, while ensuring that they rotate synchronously with the stirring rod 202 to realize full-area stirring and gas injection.

[0049] Working principle: In the initial state, the elastic band 207 is in an unstretched state, and the slider 306 is at the top of the groove 303.

[0050] When working, refer to Figures 1 to 5 As shown, the operator slowly feeds material into the tank 101 through the feeding port 104. Then, the operator connects the power supply 201 to an external power source via a conductive wire, enabling the power supply 201 to supply power to the device. After the material is fed in, the operator sends a power-on command to the receiving control circuit inside the driver 201-1 via the external control panel, energizing the power supply device inside the driver 201-1 and the power supply 201's output terminal. This causes the driver 201-1 to drive the stirring rod 202 to rotate, which in turn drives the connecting plate 203 to rotate synchronously. The connecting plate 203 then drives the scraper 204 and the sleeve 205 to rotate synchronously. During rotation, the scraper 204 scrapes away the sticky material adhering to the inner wall of the tank 101. During the rotation of the sleeve 205, the sleeve 205 drives the rotating stirring plate 206 to rotate synchronously. During the rotation of tank 101, the mixed materials are stirred. Then, the operator connects the gas supply valve 301 to the external gas supply device, so that the external gas supply device delivers high-pressure gas into the gas supply valve 301. The high-pressure gas enters the gas inlet 316 through the gas guide valve 302, and then enters the folded tube 317 and folded tube 318 through the gas guide port 316. The high-pressure gas is then sprayed out through the nozzle 315. Then, the operator sends a power-on command to the receiving control circuit set inside the drive telescopic sleeve 305 through the external control panel, so that the power supply device set inside the drive telescopic sleeve 305 and the power supply device set inside the driver 201-1 are powered on. This causes the telescopic end of the drive telescopic sleeve 305 to slowly and uniformly extend and retract. The telescopic end of the drive telescopic sleeve 305 drives the adjusting block 307 to slide up and down synchronously on the outer wall of the stirring rod 202.

[0051] During the process of the extension of the telescopic sleeve 305 and the stirring rod 202 driving the stirring plate 206 to stir the mixture, the telescopic sleeve 305 causes the slider 306 to slide downward inside the groove 303, causing the telescopic sleeve 305 to drive the adjusting block 307 to slide downward synchronously on the outer wall of the stirring rod 202, causing the adjusting block 307 to drive the connecting rod 308 to move downward synchronously, causing the connecting rod 308 to drive the adjusting block 309 to move downward synchronously on the outer wall of the stirring rod 202, causing the adjusting blocks 307 and 309 to drive the adjusting rod 310 rotatably connected to them to move downward synchronously, causing the adjusting rod 310 to drive the hinge plate 311 to move downward synchronously, causing the hinge plate 311 to drive the fixed plate 312 rotatably connected to its bottom end to flip synchronously, causing the top of the fixed plate 312 to tilt downward and flip away from the stirring rod 202, causing the fixed plate 312 to rotate around the shaft 313. The rotation of the fixed plate 312 causes the shaft 313 to rotate synchronously inside the mounting groove 304. During the rotation of the fixed plate 312, the fixed plate 312 drives the stirring plate 314, which is fixedly connected to it, to rotate synchronously. This causes the nozzle 315, which is fixedly connected to the bottom end, to rotate synchronously. During the rotation of the nozzle 315, the nozzle 315 sprays high-pressure gas synchronously. Under the action of the stirring rod 202, the nozzle 315, the fixed plate 312, and the stirring plate 314 rotate synchronously. This causes the mixture between the two stirring plates 314 in the vertical direction to be stirred, expanding the stirring area of ​​the stirring plate 314. This increases the area where the nozzle 315 sprays high-pressure gas into the tank 101, thereby improving the stirring effect of the device. Conversely, during the retraction of the telescopic sleeve 305, the fixed plate 312 can drive the nozzle 315 to rotate in the opposite direction, stirring the material inside the tank 101.

[0052] During the upward retraction of the drive telescopic sleeve 305, the drive telescopic sleeve 305 causes the adjusting block 307 to move upward synchronously, which in turn causes the connecting rod 308 to move upward synchronously. The connecting rod 308 then causes the bottom end of the hinge plate 212 to move vertically upward, causing the bottom end of the hinge plate 212 to slide the connecting sleeve 210 on the outer wall of the connecting plate 203 towards the side closest to the groove 211. This causes the connecting sleeve 210 to move the hinge rod 209, which is hinged to it, synchronously. The hinge rod 209 then moves the hinge block 208, which is hinged to it, synchronously. Finally, the hinge block 208 causes the stirring plate 206 to begin moving around the sleeve 205 as its axis. The stirring plate 206 is flipped towards one side of the groove 211, thereby adjusting the angle of the stirring plate 206 in stirring the mixture. At the same time, as the stirring plate 206 flips towards the side closer to the groove 211, it bends the elastic band 207, so that the elastic band 207 can always seal the gap between the two stirring plates 206 after it is extended. As the stirring plate 206 flips towards the side closer to the groove 211, it moves the material around the inner wall of the tank 101 towards the side closer to the stirring plate 214. This not only improves the fluidity of the material, but also prevents the material around the inner wall of the tank 101 from not being effectively stirred, thus ensuring the uniformity of the stirring.

[0053] The stirring plate 206 is curved towards the stirring rod 202, and with the elastic silicone band 207 between the two plates, when the driver 201-1 drives the stirring rod 202 to rotate, the reciprocating oscillation of the curved structure allows the viscous material around the stirring plate 206 to move towards the center of the inner side of the tank 101. This ensures that the viscous material comes into contact with the stirring plate 314 and is thoroughly mixed, avoiding the problem of insufficient mixing of viscous material near the inner wall of the tank 101. The elastic band 207 can also seal the gaps between the stirring plates 206 to prevent the material from being mixed. The material can be stuck, but it can also bend adaptively as the mixing plate 206 flips, reducing the leakage of viscous material from the gap between the mixing plates 206. This improves the effect of the mixing plate 206 in pushing the viscous material towards the center of the tank 101, thereby improving the mixing effect of the viscous material. At the same time, the scrapers 204 at both ends of the connecting plate 203 are in contact with the inner wall of the tank 101. When the connecting plate 203 rotates, it can scrape off the viscous material attached to the tank wall, which reduces material waste and avoids residual material from affecting the subsequent mixing effect, thus indirectly ensuring the uniformity of mixing.

[0054] The drive telescopic sleeve 305 within the adjustment mechanism 300 drives the adjustment block 307 and adjustment block 309 to slide, causing the adjustment rod 310 to rotate in conjunction with the hinge plate 311 and the fixed plate 312, thereby expanding the mixing coverage area of ​​the mixing plate 314. Combined with the rotation of the mixing rod 202, this achieves full-area mixing of materials within the tank 101 without dead angles. Simultaneously, it drives the nozzle 315 to move synchronously, and through the set gas nozzles, forms a synergistic effect of mechanical mixing and gas jet. The shearing action of the side nozzles can disrupt the flow field mixing isolation zone, while the rear nozzles can enhance the degree of liquid turbulence, effectively solving the problems of agglomeration and stratification of high-viscosity asphalt and modifiers. At the same time, combined with the overall temperature control system of the device and the staged feeding design of the feeding structure, it ensures that all components fully penetrate and blend, significantly improving the uniformity and bonding strength of the finished product and reducing the performance differences between batches.

[0055] The stirring plate 206 is connected to the connecting sleeve 210 via the hinge block 208 and hinge rod 209, causing the connecting sleeve 210 to slide along the connecting plate 203. This causes the stirring plate 206 to rotate around the sleeve 205, allowing the viscous material on one side of the inner wall of the tank 101 to move towards the middle of the tank 101, thereby increasing the fluidity of the material inside the tank 101. In addition, through the adjustment mechanism 300, the telescopic sleeve 305 drives the adjustment block 307 and adjustment block 309 to slide along the stirring rod 202, causing the adjustment rod 310 and hinge plate 311 to drive the fixed plate 312 to rotate around the shaft 313. This changes the stirring posture and coverage of the stirring plate 314. Combined with the rotational movement of the stirring rod 202, targeted stirring of different areas in the upper, middle, and lower parts of the tank 101 can be achieved, avoiding insufficient stirring in certain areas.
