Description

Technical Field

[0001] The utility model relates to an asphalt processing device, in particular to a modified asphalt combined reaction device. Background Art

[0002] Asphalt is a kind of high-viscosity organic liquid, mainly used in industries such as coatings, plastics, rubbers, etc. and for paving roads. Modified asphalt is an asphalt binder in which rubber, resin, polymer, rubber powder or other fillers (modifiers) are added to the original asphalt material in proportion. Compared with ordinary asphalt materials, it has better flexibility and elasticity, and its service life is significantly enhanced.

[0003] In related technologies, during the processing of modified asphalt, medium-temperature asphalt needs to enter multiple reaction kettles in sequence, and the temperature of the asphalt material needs to be kept stable at about 370 degrees Celsius when entering the kettles. At present, when transporting modified asphalt between different reaction kettles, it is generally after the reaction kettle stops operating, and the asphalt is transferred between the reaction kettles through a pumping device.

[0004] Regarding the above-mentioned related technologies, the inventor believes that during the transfer process of asphalt, when the asphalt is transferred by pumping, the transportation speed is limited, and the asphalt temperature is relatively high. When continuously pumping, the pump machine heats up quickly, the pressure on the pump machine unit is relatively high, and the transfer speed of the asphalt is relatively limited. In addition, when the asphalt is transferred by pumping, the asphalt temperature is likely to change, resulting in the need for temperature adjustment of the raw material before entering the kettle, generating additional energy consumption. Summary of the Invention

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a modified asphalt combined reaction device. By arranging the reaction kettles adjacent to each other, and setting a mutually matching feeding docking mechanism and discharging docking mechanism between adjacent reaction kettles to connect each reaction kettle to each other, rapid transfer of asphalt materials is realized, so as to solve the problems of slow asphalt transfer speed and large temperature change before entering the kettle in related technologies.

[0006] To achieve the above purpose and other related purposes, the present invention provides a modified asphalt combined reaction device, including a plurality of reaction kettles; a feeding docking mechanism and a discharging docking mechanism are arranged on each of the reaction kettles. The feeding docking mechanism is arranged at the top of the side wall of the reaction kettle, and the discharging docking mechanism is arranged at the bottom of the reaction kettle. Between two adjacent reaction kettles, the corresponding discharging docking mechanism and the feeding docking mechanism are mutually adapted; a kettle body lifting mechanism is further arranged on the reaction kettle, and the kettle body lifting mechanism is used to drive the reaction kettle to move in the vertical direction.

[0007] Further, the feeding docking mechanism includes a feeding port arranged at the top of the side wall of the reaction kettle. A feeding pipe is arranged at the feeding port, and a feeding plug valve is arranged at the feeding pipe. The discharging docking mechanism includes a discharging port arranged at the bottom of the reaction kettle. A drainage pipe is arranged at the discharging port, and a discharging plug valve capable of closing the discharging port is arranged on the drainage pipe. The pipe orifice at the end of the drainage pipe away from the reaction kettle is adapted to the pipe orifice of the feeding pipe on the adjacent reaction kettle.

[0008] Further, a feeding sleeve is arranged at the pipe orifice of the feeding pipe. The feeding sleeve is sleeved on the feeding pipe and can slide along the axial direction of the feeding pipe. A driving cylinder is arranged on the pipe wall of the feeding pipe. The piston rod of the driving cylinder is parallel to the axial direction of the feeding pipe and is fixedly connected to the feeding sleeve.

[0009] Further, a plurality of guide posts are arranged below the reaction kettle. A stable support is arranged at the bottom of the reaction kettle, and a guide ring matched with the guide posts is arranged on the stable support.

[0010] Further, a stable plate is arranged at the bottom of the stable support.

[0011] Further, a plurality of air springs are arranged at the bottom of the reaction kettle.

[0012] Further, the bottom ends of the air springs are all in contact with the ground.

[0013] Further, the reaction kettle lifting device includes an electric hoist, and a lifting ear for connecting the electric hoist is arranged at the top of the reaction kettle.

[0014] As described above, the utility model has at least the following beneficial effects:

[0015] 1. By arranging a plurality of reaction kettles adjacent to each other, and by arranging a feeding docking mechanism and a discharging docking mechanism on each reaction kettle, after the asphalt material is stirred and reacted in one of the reaction kettles, through the adaptation and connection of the feeding docking mechanism and the discharging docking mechanism, and after lifting the discharging reaction kettle, under the action of gravitational potential energy, the asphalt can be quickly transferred to another reaction kettle. Since the distance between the reaction kettles is close and the conveying distance of the asphalt is short, the temperature change during the asphalt transfer process is smaller;

[0016] 2. By arranging the feeding sleeve to improve the sealing performance when the feeding pipe and the drainage pipe are connected, reducing the possibility of asphalt leakage during the transfer process;

[0017] 3. By arranging the cooperation of the guide posts and the guide rings on the stable support to limit the reaction kettle, making the lifting movement track of the reaction kettle more stable;

[0027] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0028] Please refer to Figures 1 to 5, the present utility model provides a modified asphalt combined reaction device, including several adjacent reaction kettles 1. In this embodiment, the number of reaction kettles 1 is selected as 3, which are respectively denoted as the No. 1 reaction kettle 1, the No. 2 reaction kettle 1, and the No. 3 reaction kettle 1. Each reaction kettle 1 is provided with a feeding docking mechanism 2 and a discharging docking mechanism 3. The feeding docking mechanism 2 and the corresponding discharging docking mechanism 3 between adjacent reaction kettles 1 are adapted to each other. Each reaction kettle 1 is also equipped with a kettle body lifting mechanism for driving the reaction kettle 1 to move in the vertical direction. When asphalt is modified and processed, it needs to be reacted and processed in the No. 1 reaction kettle 1, the No. 2 reaction kettle 1, and the No. 3 reaction kettle 1 in sequence. During the transfer of asphalt, taking the transfer from the No. 1 reaction kettle 1 to the No. 2 reaction kettle 1 as an example, when the asphalt is processed in the No. 1 reaction kettle 1, under the action of the kettle body lifting mechanism, the No. 1 reaction kettle 1 rises until the discharging docking mechanism 3 of the No. 1 reaction kettle 1 is docked with the feeding docking and structure of the No. 2 reaction kettle 1. Then, under the action of gravitational potential energy, the asphalt enters the No. 2 reaction kettle 1 from the No. 1 reaction kettle 1. Since the transfer path of the asphalt is short and the speed is fast, the transfer efficiency of the asphalt is high and the temperature change is small, and the reaction kettle 1 can be transferred at a constant temperature between each reaction kettle 1.

[0029] The feeding docking mechanism 2 includes a feeding port 21 opened at the top of the side wall of the reaction kettle 1. A feeding pipe 22 is arranged at the feeding port 21. A feeding plug valve 23 is arranged at the connection between the feeding pipe 22 and the feeding port 21. A feeding sleeve 24 is arranged at the pipe orifice of the feeding pipe 22 far from the reaction kettle 1. The feeding sleeve 24 is sleeved on the outer periphery of the feeding pipe 22, and the feeding sleeve 24 can move along the axial direction of the feeding pipe 22. A driving cylinder 241 is fixedly installed on the feeding pipe 22. The piston rod of the driving cylinder 241 is arranged parallel to the axis of the feeding pipe 22, and the piston rod of the driving cylinder 241 is fixedly connected with the feeding sleeve 24.

[0030] The discharging docking mechanism 3 includes a discharging port 31 arranged at the bottom of the reaction kettle 1. A drainage pipe 32 is arranged at the discharging port 31. One end of the drainage pipe 32 close to the bottom of the reaction kettle 1 is funnel-shaped. The end of the drainage pipe 32 far from the reaction kettle 1 extends obliquely downward. The drainage pipe 32 and the feeding pipe 22 of the adjacent reaction kettle 1 are in the same plane. A discharging plug valve 33 is arranged at the pipe orifice of the drainage pipe 32 close to the reaction kettle 1.

[0031] The main function of the kettle body lifting mechanism is to drive the corresponding reaction kettle 1 to move in the vertical direction. The kettle body lifting mechanism can be a hydraulic lifting mechanism (such as a hydraulic cylinder), a pneumatic lifting mechanism (such as a cylinder), or a hoisting mechanism. In this embodiment, a hoisting mechanism with a lower cost is selected, specifically the cooperation of an electric hoist and a lifting rope, and a lifting ear 11 cooperating with the lifting rope is arranged at the top of the reaction kettle 1. In the kettle body lifting mechanism, the electric hoist and the lifting rope are both commonly used devices in the prior art, so they are not shown in the drawings.

[0032] The bottom of the reactor 1 is provided with a stabilizing support 5, and the bottom of the stabilizing support 5 is provided with a stabilizing plate 52. The stabilizing support 5 supports the reactor 1, so that a certain gap is left between the reactor 1 and the ground for the installation of the drainage pipe 32. The provision of the stabilizing plate 52 increases the contact area between the stabilizing support 5 and the ground, thereby reducing the shaking of the reactor 1 during operation and improving stability.

[0033] A plurality of guide posts 4 are arranged on the foundation below each reactor 1, and a guide ring 51 matched with the guide posts 4 is arranged on the stabilizing support 5. The guide posts 4 are matched with the corresponding guide rings 51. On the one hand, the guide posts 4 limit the movement trajectory of the reactor 1 during the lifting process, and on the other hand, the cooperation between the guide posts 4 and the guide rings 51 can also control the vibration of the reactor 1 during the processing process, thereby improving the overall stability of the equipment. In this embodiment, in order to avoid interference between different components, two guide posts 4 are arranged, and one of the guide posts 4 is shorter to make room for the asphalt transfer channel. However, during the lifting process of the reactor 1, there are still two guide posts 4 that are always matched with the corresponding guide rings 51 to maintain the stability of the movement trajectory of the reactor 1.

[0034] A plurality of air springs 6 are arranged below the reactor 1. The lower end of the air spring 6 is connected to the ground, and the top end is connected to the bottom of the reactor 1. When the reactor 1 is raised to the point where the corresponding feed docking mechanism 2 is connected to the corresponding discharge docking mechanism 3, the air springs 6 below the reactor 1 are in a natural state. In this embodiment, in order to adapt the length of the air spring 6 to the rising stroke of the reactor 1, a foundation pit is opened on the ground below the reactor 1, and the air spring 6 is installed in the foundation pit to install the air spring 6 with a longer total length, thereby obtaining a sufficient telescopic length. The air spring 6 plays a buffering role for the lifting and lowering movement of the reactor 1, and offsets part of the weight of the reactor 1 during the lifting and lowering process of the reactor 1, thereby reducing the pressure on the escalator lifting mechanism.

[0035] The implementation principle of this embodiment is:

[0036] By arranging a plurality of reactors 1 adjacent to each other and arranging a feed docking mechanism 2 and a discharge docking mechanism 3 on each reactor 1, after the asphalt material is stirred and reacted in one of the reactors 1, the feed docking mechanism 2 and the discharge docking mechanism 3 can be adapted and connected, and the reactor 1 with the discharge material can be lifted up, and the asphalt can be quickly transferred to another reactor 1 under the action of gravity potential energy. Since the distance between the reactors 1 is short and the asphalt transportation distance is short, the temperature change during the asphalt transportation process is smaller;

[0037] During the asphalt reaction process, the stirring device in the corresponding reactor 1 rotates at a normal speed. After the asphalt material is output and the reactor 1 is lifted by the reactor lifting mechanism, the stirring device in the reactor 1 still operates, but the movement speed of the stirring device decreases. Thus, while maintaining the flow of asphalt to accelerate the transfer speed, the shaking of the reactor 1 caused by the rotation of the stirring device is reduced, and the overall stability of the equipment is improved.

[0038] By setting the feed sleeve 24, the sealing performance when the feed pipe 22 and the diversion pipe 32 are connected is improved, and the possibility of asphalt leakage during the transfer process is reduced.

[0039] By setting the cooperation of the guide column 4 and the guide ring 51 on the stable support 5, the reactor 1 is limited, making the lifting movement trajectory of the reactor 1 more stable.

[0040] By setting the stable plate 52, the contact area between the reactor 1 and the ground is increased, and the stability of the reactor 1 is improved during the operation of the reactor 1.

[0041] By setting the air spring 6, the lifting movement of the reactor 1 is buffered, and the pressure on the reactor lifting mechanism is reduced.

[0042] Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0043] The above embodiments are only illustrative of the principles and effects of the present invention and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
