Description

Technical Field

[0001] The utility model relates to the technical field of rubber composite modified asphalt preparation, in particular to an environmentally friendly high-content rubber composite modified asphalt preparation system. Background Art

[0002] With the rapid development of road traffic, asphalt, as the main road paving material, has become increasingly demanding in terms of performance and environmental protection. Currently, there is technology that modifies asphalt by adding rubber powder to improve its wear resistance and crack resistance.

[0003] The existing rubber composite modified asphalt is mainly prepared by using a mixing tank with a heating mechanism and a mixing mechanism to achieve the mixing preparation of rubber powder and asphalt raw materials. Although the mixing tank of this structure can achieve the preparation of rubber composite modified asphalt, when the rubber powder is added during the preparation process, since the rubber powder is directly added to the mixing tank, it is easy to cause insufficient mixing of the rubber powder with the asphalt raw materials after addition due to the presence of impurity particles in the rubber powder, resulting in poor preparation quality of the rubber composite modified asphalt. At the same time, the harmful exhaust gas generated in the mixing tank of the above structure during use is mostly directly discharged to the external environment, resulting in pollution to the surrounding environment during the preparation of the rubber composite modified asphalt. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an environmentally friendly high-dosage rubber composite modified asphalt preparation system based on the current status of the existing technology, which can not only vibrate and screen the rubber powder when adding it to prevent large impurities mixed in the rubber powder from entering the mixing box, but also adsorb and purify the exhaust gas discharged during the preparation process to avoid pollution of the surrounding environment during the preparation of the rubber composite modified asphalt.

[0005] The present invention is realized through the following technical scheme: The present invention proposes an environmentally friendly high-content rubber composite modified asphalt preparation system, comprising a mixing box, a box cover is installed on the top of the mixing box, a feeding box is welded to one side of the top of the box cover, a screening mechanism is installed in the feeding box, the screening mechanism comprises a fixed frame installed on the inner wall of the feeding box, springs evenly distributed on the upper end of the fixed frame, a screen arranged on the top of the spring and a vibration motor installed around the bottom end of the screen, an exhaust pipe is also welded on the other side of the upper end of the box cover, an adsorption purification component is installed in the exhaust pipe, the adsorption purification component comprises a pull-out plate, two sets of mounting rails installed on the pull-out plate facing the side wall of the exhaust pipe and an activated carbon mesh plate installed on each set of the mounting rails.

[0006] By adopting the above technical solution, when rubber powder needs to be added through the feeding box during the production process of rubber composite modified asphalt, the rubber powder is directly added to the screen, and then the screen is vibrated under the action of the vibration motor and the spring. After the vibration of the screen, the rubber powder will be screened to ensure that large particles of impurities in the rubber powder can be intercepted, and the screened rubber powder can smoothly enter the mixing box to ensure that the rubber powder can be fully mixed with the asphalt raw material, thereby ensuring the preparation quality of the final rubber composite modified asphalt. The exhaust gas generated during the production process will be adsorbed and purified when passing through the activated carbon mesh plate in the adsorption purification component, thereby effectively avoiding the exhaust gas from polluting the surrounding environment, making the device more environmentally friendly.

[0007] Furthermore, the fixing frame is connected to the feeding box with bolts, the top end of the spring is welded to the frame of the screen, and the bottom end of the spring is welded to the fixing frame.

[0008] By adopting the above technical solution, the spring can ensure that the screen can vibrate up and down conveniently relative to the fixed frame.

[0009] Furthermore, the mounting rail is welded to the pull-out plate, a pull handle is provided on the outer wall of the pull-out plate, and the activated carbon mesh plate is slidably connected to the mounting rail.

[0013] Furthermore, the material blocking mechanism includes a material blocking plate slidably mounted on the feeding box and an electric telescopic rod installed between the material blocking plate and the outer wall of the feeding box.

[0014] By adopting the above technical solution, the material blocking mechanism is mainly used to control the connection and disconnection between the feeding box and the mixing box, ensuring that the feeding box and the mixing box are not connected when no material is added, so as to realize the centralized discharge of waste gas through the exhaust pipe during the preparation process.

[0015] Furthermore, the material baffle is an L-shaped structure, and the electric telescopic rod is connected to the feeding box and the material baffle by bolts.

[0016] By adopting the above technical solution, it is possible to ensure that the baffle plate can slide conveniently relative to the feeding box.

[0017] Furthermore, two heating plates are symmetrically installed on the two side walls of the mixing box, and a mixing mechanism is also installed in the mixing box between the heating plates. The mixing mechanism includes a mixing rack installed in the middle of the mixing box and a mixing motor installed on the outer wall of the mixing box facing the mixing rack.

[0022] The utility model installs a screening mechanism in the feeding box, so that when rubber powder is added during the preparation process of the rubber composite modified asphalt, the rubber powder can be screened and filtered under the action of the vibration motor, spring, and screen in the screening mechanism, thereby preventing large particles in the rubber powder from entering the mixing box, ensuring sufficient mixing of the rubber powder and the asphalt raw material, and improving the preparation quality of the rubber composite modified asphalt. At the same time, by installing an adsorption purification component in the exhaust pipe, the activated carbon mesh plate in the adsorption purification component can be used to adsorb and purify the exhaust gas, thereby avoiding pollution to the surrounding environment during the preparation of the rubber composite modified asphalt, and making the device more energy-saving and environmentally friendly.

When the rubber powder is added through the feeding box 1 during the preparation process, the vibration motor 1002, the spring 1004, and the screen 1001 in the screening mechanism 10 are used for screening and filtering to prevent large particles in the rubber powder from entering the mixing box 5, ensuring that the rubber powder and the asphalt raw materials are fully mixed, so that the preparation quality of the rubber composite modified asphalt is better.
