Problems solved by technology

This scheme solves the problem of waste asphalt removal and recycling very well, but there are still some key technical problems that have not been resolved: 1. There are many dust impurities and wastes condensed on the surface of the waste road surface, which will affect the new construction if it is used for re-construction without removal. The quality of the road surface; 2. Using a coil heating device to heat the road surface consumes a lot of energy, the cost is too high, and the efficiency is too low; 3. The cutting device uses a single cutter to cut the road surface vertically and horizontally, and the efficiency is low; 4. The heating box of the regeneration device The direct heating efficiency of the coil is low; the filter screen under the coil cannot effectively exert the filtering effect, because the asphalt is very viscous, and the speed of passing through the screen is extremely slow; at the same time, stones and sand are easy to block the mesh and reduce the filtering effect

Embodiment 1

[0053] Such as figure 1 , 2 Shown in and 3, a kind of highway waste and old asphalt of the present invention rejects regeneration construction integrated device, comprises:

[0054] The car body 1 is fixed with a high-pressure air pump 2 and a steam furnace 3. The high-pressure air pump 2 extracts steam from the steam furnace 3 and pressurizes the steam. The specific positions of the high-pressure air pump 2 and the steam furnace 3 can be determined according to the device space of the car body set up;

[0055] Shoveling device 4, which is arranged on the car body 1, protrudes from the bottom of car body 1, contacts with the ground, and shovels off the surface layer of the road surface when car body 1 moves. Said shoveling device 4 includes a shovel handle 5, The blade 6 and the connector 7, the first end of the shovel handle 4 is hinged to the bottom of the car body 1, and the second end extends forward and downward to be close to the ground so that an angled area is formed...

Embodiment 2

[0070] In the above-mentioned embodiment 1, in order to improve the heating effect, the drum heating device can be another scheme, as follows: figure 1 , 2 As shown in and 4, the drum heating device 15 includes:

[0071] The outer drum 18 has an open upper end and a closed lower end, and an outlet 23 for discharging asphalt is provided on the lower end or the side wall; the function of the outer drum 18 is to collect asphalt.

[0072]The inner drum 19 is rotatably arranged inside the outer drum 18, and there is a gap between them. The upper end of the inner drum 19 has an inlet for receiving waste asphalt, the side wall has mesh holes to form a screen, and the lower end has a The discharge port 22, the discharge port 22 can stretch out of the first drum 18, and the joint between the discharge port 22 and the first drum 18 is provided with a bearing, so that the second drum can rotate relative to the first drum; the inner drum Including the upper half 25 and the lower half 26...

Abstract

The invention discloses an integrated device for highway waste asphalt removing and regenerating construction. The integrated device for highway waste asphalt removing and regenerating construction comprises a vehicle body, a removing device, a plurality of cutting devices, a conveying device and a roller heating device, wherein the removing device is used for removing impurities on the surface layer of an asphalt pavement and preheating the pavement; the cutting devices are used for cutting the pavement transversely and longitudinally, so that lump materials are obtained; the conveying device is used for shoveling the lump materials up and conveying the lump materials to the roller heating device; and the roller heating device is used for melting the lump materials and separating asphalt from the impurities. According to the integrated device for highway waste asphalt removing and regenerating construction, the impurities on the surface layer of the pavement are removed through the removing device, the pavement is cut into the lump materials through the cutting devices, and the screening efficiency is improved through the roller heating device. The removing device integrates a heating function and a removing function, so that the efficiency is improved. The multiple cutting devices are arranged in parallel and integrate a heating function and a cutting function, and thus the structure is simplified. The roller heating device rotates at a high speed, and heating and screening are rapid.

Description

technical field [0001] The invention relates to the field of asphalt pavement construction, more specifically, the invention relates to an integrated device for removing and regenerating road waste asphalt. Background technique [0002] When the asphalt pavement needs maintenance and maintenance, the traditional method is to use manual or mechanical methods to cut out the waste asphalt on the road surface, use vehicles to transport the waste asphalt away, and then pave new asphalt. Such a method is time-consuming and laborious, and the waste asphalt is not effectively utilized, so it is very wasteful. [0003] The patent with application number 201410727611.6 discloses an integrated device for removing and recycling road waste asphalt and its construction method. In this solution, a heating device is installed on the car body to preheat the road surface, and then a cutting device is used to cut the road surface into blocks. , the block material is transported to the regener...
