Description

Technical Field

[0001] This invention relates to the field of asphalt material mixing technology, specifically to a mixing device for preparing fog seal material and its usage method. Background Technology

[0002] Construction and maintenance are the two major themes of highway development. Construction represents active development, while maintenance represents sustainable development. Highway construction is the foundation, and maintenance management is the guarantee. Preventive maintenance is an effective means to alleviate the shortage of funds for road surfaces and extend their service life. Currently, the main preventive maintenance measures for road surfaces include fog seal, micro-surfacing, slurry seal, chip seal, super-adhesive wearing course, thin overlay, composite overlay, milled overlay, plant-mixed and in-situ hot recycling, etc. Among them, fog seal utilizes the direct spraying of asphalt mixture materials, which has the characteristics of low cost, fast construction speed, and rapid restoration of road surface traffic, and is therefore widely used.

[0003] According to Chinese Patent Application No. 202010756782.7, a high-performance sand-containing fog seal material and its preparation method are disclosed, belonging to the field of road engineering technology. The material composition includes amphoteric emulsified asphalt, suspending thickener, thickening and toughening agent, film-forming agent, suspending agent, corrosion inhibitor, and anti-skid fine sand. The preparation method includes preparing the base material, preparing the sand-containing fog seal concentrate, preparing the high-performance sand-containing fog seal material, and construction. The comparative example shows that the finger-drying time of the sand-containing fog seal material is 10-30 min, and the pull-out strength at 60℃ is 0.35-1.

[0004] 0.1MPa, wet wheel abrasion value of 22.8~56g / m2, uniform suspension of diamond abrasive after 7 days, service life of more than 3 years, the high temperature pull-out strength of the comparative ratio is at least 20% higher than that of existing traditional sand-containing mist sealing materials, which can solve the problems of poor high temperature adhesion and poor wear resistance of existing materials, and has the advantages of short drying time, good curing effect and long service life.

[0005] The comparison shows that the addition and mixing of sand-containing materials can support fog seal materials with good annual and anti-skid properties. However, before the material is sprayed onto the ground, it needs to be demulsified. In order to ensure that the carborundum can remain suspended and uniform in the emulsified asphalt for a long time, the particle size and content of carborundum are limited. Therefore, it is not convenient to combine materials such as carborundum to improve friction according to the usage requirements. Summary of the Invention

[0006] The purpose of this invention is to provide a mixing device and its method for preparing fog seal materials. It has the advantages of being convenient for mixing and demulsifying according to needs. It solves the problem that the material still needs to be demulsified before being sprayed onto the ground, and that the particle size and content of the carborundum are limited in order to ensure that the carborundum can remain suspended and uniform in the emulsified asphalt for a long time. Therefore, it is inconvenient to combine materials such as carborundum to improve friction according to the needs of use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for preparing fog sealing material, comprising a mounting plate, a connecting unit provided on one side of the top of the mounting plate, a mixing unit provided on the other side of the top of the mounting plate, a mixing mechanism provided at the front end of the top of the mounting plate, a spraying unit provided in front of the mixing mechanism, the spraying unit and the mounting plate being threadedly connected to an external moving vehicle by bolts, the mixing mechanism comprising a mounting cylinder, the mounting cylinder being fixedly connected to the top of the mounting plate, the mixing unit being provided in the inner cavity of the mounting cylinder, a pump being fixedly connected to the front of the mounting cylinder, one end of the pump being connected to the mounting cylinder, and the other end being connected to a conveying pipe.

[0008] Preferably, the mixing unit includes a mounting barrel, a mounting frame is fixedly connected to the top of the mounting barrel, a motor is fixedly connected to the top of the mounting frame, a connecting plate is movably connected to the inner cavity of the mounting barrel, and mixing rods are fixedly connected to all four sides of the bottom of the connecting plate.

[0009] Preferably, the mixing unit further includes a feeding bucket, which is fixedly connected to one side of the mounting frame and has a through groove at its bottom communicating with the inner cavity of the mounting bucket. Both the top of the feeding bucket and the output shaft of the motor are provided with pulleys, which are connected by a belt drive. The output shaft of the motor is driven by one end of one of the pulleys. An auger is movably connected to the inner cavity of the feeding bucket, with one end of the auger penetrating the feeding bucket and fixedly connected to the pulley on the other side. The output shaft of the motor passes through one of the pulleys and is driven by a connecting plate.

[0010] Preferably, the mixing mechanism further includes a connecting frame, which is fixedly connected to one side of the mounting cylinder. One side of the connecting frame is connected to a discharge block, and one end of the discharge block extends into the inner cavity of the mounting cylinder and communicates with the inner cavity of the mounting cylinder.

[0011] Preferably, the connecting unit includes a connecting frame, which is fixedly connected to the top of the mounting plate. A feeding pump is fixedly connected to one side of both the connecting frame and the mounting barrel. The two inlets of the two feeding pumps extend through conduits to the inner cavities of the mounting barrel and the connecting frame, respectively. The outlets of the two feeding pumps are connected to the inner cavity of the connecting frame.

[0012] Preferably, the mixing unit includes a rotating rod, which is movably connected to the inner wall of the mounting cylinder. A push plate is fixedly connected to the surface of the rotating rod, and a curved rod is fixedly connected to the surface of the rotating rod and to one side of the push plate. Limiting plates are fixedly connected to the bottom and the bottom of the inner cavity of the mounting cylinder. One end of the curved rod extends into the inner cavity of the limiting plate and is movably connected to the inner cavity of the limiting plate. The push plate is located in front of the discharge block.

[0013] Preferably, the spraying unit includes a spraying plate, the feed pipe of the pump outlet is connected to the spraying plate, and the bottom of the spraying plate is connected to a nozzle.

[0014] Preferably, the steps for its use are as follows:

[0015] A. First, place the prepared emulsified asphalt material in the connecting frame and extend the feed inlet pipe of the conveying pump into the material cylinder. At the same time, add the demulsifier and water into the inner cavity of the installation bucket in proportion, and fill the inner cavity of the filling bucket with the required particle size of the diamond abrasive material.

[0016] B. Next, the motor is started through the external controller. The output shaft of the motor drives the two pulleys to rotate, and also drives the connecting plate to rotate. The connecting plate stirs and mixes the demulsifier and water. At the same time, the rotation of the pulleys drives the auger to rotate, and gradually transports the diamond material in the feeding tank to the inner cavity of the installation tank, where it is stirred with the demulsifier and water, thus completing the linkage mixing of the demulsifier, water and diamond material.

[0017] C. Then, the material pump is started by the external controller. The material pump delivers the material from the installation bucket and the emulsified asphalt material bucket to the inner cavity of the connecting frame, and sprays it into the inner cavity of the installation cylinder through the discharge block. During the process, the sprayed material drives the push plate and the rotating rod to rotate, which in turn drives the curved rod to move along the inner cavity of the limiting plate, thereby mixing the emulsified asphalt material and the demulsifier mixture. The material conveying and mixing operations are completed in a coordinated manner.

[0018] D. Finally, the pump is started to extract the mixed material from the inner cavity of the installation cylinder and spray it onto the ground through the spray plate and nozzle. As the external mobile vehicle moves, the material spraying operation on the road surface begins, forming a fog seal layer. The emulsified asphalt material itself has good adhesion under the action of the tackifier, and the demulsifier improves its water resistance. In addition, the added diamond abrasive material increases the wear resistance and anti-slip properties of the fog seal layer.

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

[0020] This invention provides support for the connecting unit, mixing unit, and mixing mechanism by setting an installation plate. The connecting unit can be used to limit the emulsified asphalt material in the cylinder and to transport the material in conjunction with the mixing unit. The mixing unit can mix the demulsifier required for spraying and add wear-resistant materials such as corundum in conjunction with it. The materials can be selected regardless of the viscosity and uniformity requirements of the emulsified asphalt material, thus better meeting the wear resistance and anti-skid requirements of the road surface. The mixing mechanism is used to mix the demulsifier, asphalt, and corundum materials, and the mixing operation is carried out using the material conveying connection of the connecting unit. The spraying unit works with the mixing mechanism to spray the mixed materials, thereby completing the spraying of the fog seal layer on the road surface and protecting the original asphalt pavement. This allows for easy addition of materials in the mixing unit according to the road surface usage requirements, and by demulsifying the asphalt material, the water resistance of the fog seal layer is improved, achieving the effect of on-site construction mixing.

[0044] A. First, place the prepared emulsified asphalt material in the connecting frame 21, and extend the feed inlet pipe of the feed pump 22 into the material cylinder. At the same time, add the demulsifier and water into the inner cavity of the installation bucket 31 in proportion, and fill the inner cavity of the filling bucket 36 with the required particle size of the diamond abrasive material.

[0045] B. Next, the motor 33 is started by the external controller. The output shaft of the motor 33 drives the two pulleys 37 to rotate and drives the connecting plate 34 to rotate. The connecting plate 34 stirs and mixes the demulsifier and water.

During the process, the sprayed material drives the push plate 452 and the rotating rod 451 to rotate, which in turn drives the curved rod 453 to move along the inner cavity of the limiting plate 454, thereby mixing the emulsified asphalt material and the demulsifier mixture, and completing the material conveying and mixing operations in a coordinated manner.

[0047] D. Finally, the pump 42 is started to extract the mixed material from the inner cavity of the installation cylinder 41 and spray it onto the ground through the spray plate 51 and nozzle 52. As the external mobile vehicle moves, the material spraying operation on the road surface begins, forming a fog seal layer. The emulsified asphalt material itself has good adhesion under the action of the tackifier, and the demulsifier improves its water resistance.
