Description

Technical Field

[0001] The invention relates to the technical field of modified asphalt processing, in particular to modified asphalt processing equipment. Background Art

[0002] With the rapid growth of highway traffic construction in my country, road transportation is becoming increasingly busy, and asphalt pavement has serious problems such as rutting, cracking, and potholes. In order to comprehensively improve the performance of asphalt pavement, the use of modified asphalt is one of the effective measures. During the preparation and processing of modified asphalt, it is necessary to add rubber, resin, high molecular polymer, ground rubber powder or other fillers and other modifying materials to the asphalt raw materials, and use the preparation and processing equipment to melt, stir and mix, so that the performance of asphalt or asphalt mixture can be improved to obtain modified asphalt.

[0003] In the current asphalt modification processing equipment, during the processing and production, only a single mixing and stirring work can be performed on the asphalt raw material and the modified material. The asphalt material has a strong adhesion in the molten state. The modified material and the asphalt material cannot be mixed with each other by continuous stirring alone. The modified material and the asphalt material will gather into a mass, and the modified material wrapped in the mass is always in a dry powder state. This is a problem that cannot be solved by a single stirring method. In addition, the particle sizes contained in the modified material, the asphalt material and the agglomerated mixture are all different, which will directly affect the quality of the modified asphalt. For example, the prior art: CN114311372A, a modified asphalt The green preparation and processing technology, in the process of preparing modified asphalt, uses a reciprocating screw to drive the connecting plate to perform a stable reciprocating motion, and then drives the grinding wheels on each fixed plate to perform a stable reciprocating motion on the filter plate, so as to efficiently and stably grind and crush the modified material delivered to the filter plate. However, this technical solution still has obvious defects. For example, there are plastic materials in the modified material. In the processing equipment, since the asphalt material is in a molten state and the temperature is relatively high, it cannot be crushed by rolling and grinding. The softened modified material will only be crushed to become flat and slender, and the so-called "grinding and crushing" effect cannot be achieved.

[0004] Therefore, we propose a modified asphalt processing equipment to solve the above technical problems. Summary of the invention

[0005] The object of the present invention is to provide a modified asphalt processing equipment to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The modified asphalt processing equipment, through the design and use of reaction tanks, partitions, movable plates, hollow cylinders, spiral rollers, storage tanks, telescopic shafts, wedges and pressure strips, the asphalt is first spread on the movable plate from bottom to top, and then the modified material is spread on the asphalt, and then covered with a layer of asphalt.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a technical solution for a modified asphalt processing device:

[0028] Embodiment 1:

[0029] like Figure 1 As shown, it includes a reaction tank 1 for processing modified asphalt and a storage tank 2 installed on the top of the reaction tank 1 for storing modified material;

[0030] like Figure 3 As shown, a partition 3 is installed on the upper part of the inner wall of the reaction tank 1 through fasteners, and an annular groove 4 is opened on the inner wall of the reaction tank 1 above the partition 3. A movable plate 5 is clamped in the inner cavity of the annular groove 4, and a circulation leak hole 6 for the circulation of asphalt material is opened on the top of the movable plate 5 and the partition 3;

[0031] like Figure 3 As shown, a hollow cylinder 7 is installed through the middle of the partition 3, a spiral roller shaft 8 is inserted into the inner cavity of the hollow cylinder 7, and a notch is opened at the bottom of the outer side of the hollow cylinder 7 for asphalt to enter;

[0032] like Figure 1 As shown, a driving motor 9 is installed at the solid middle position of the storage tank 2, and the output shaft of the driving motor 9 is butt-jointed with the top of the spiral roller shaft 8;

[0033] like Figure 2 and Figure 4 As shown, a telescopic shaft 10 is installed through the bottom of the storage tank 2, a return spring 11 is mounted on the outer ring of the telescopic shaft 10, a wedge 12 is fixedly installed on the top of the telescopic shaft 10, a pressure strip 13 is installed on the outer wall of the spiral roller shaft 8 through fasteners, and a groove 14 for loading modified materials is opened on the outer wall of the telescopic shaft 10.

[0034] In this embodiment, firstly, the heated molten asphalt material is poured into the inner cavity of the reaction tank 1, then the modified material is poured into the storage tank 2, and finally the driving motor 9 is started;

[0035] The driving motor 9 drives the spiral roller 8 at the bottom to rotate through the output shaft. When the spiral roller 8 rotates, the asphalt is drawn into the bottom of the hollow cylinder 7, and then gradually moves upward along the hollow cylinder 7, and flows out from the upper port to the upper surface of the movable plate 5;

[0036] At the same time, when the spiral roller 8 rotates, it drives the pressure strip 13 thereon to rotate in a circular manner. When rotating, the pressure strip 13 will gradually squeeze the wedge block 12 in turn. The wedge block 12 is squeezed and compresses the telescopic shaft 10 at its bottom to move downward. When the telescopic shaft 10 moves, it will pass through the hole at the bottom of the storage tank 2, and then the groove 14 loaded with the modified material will extend out of the storage tank 2 and then fall on the asphalt material intercepted by the movable plate 5. During the continuous rotation of the spiral roller 8, this action occurs continuously, that is, the modified material is spread on the asphalt material layer by layer, that is, the mixing relationship between the asphalt material and the modified material is: a layer of asphalt material and a layer of modified material are in contact with each other, and finally the asphalt mixed with the modified material gradually flows into the lower space of the reaction tank 1 again from the circulation leak 6 and falls on the upper layer of the untreated asphalt material.

[0037] When the above technical solution is in use, the asphalt and the modifier are contacted and mixed by spreading them layer by layer. The asphalt is in the inner cavity of the reaction tank 1, gradually moving upward from the bottom of the asphalt and then the asphalt mixed with the modifier is dropped again. On the one hand, it ensures that all the asphalt can contact the modifier. On the other hand, the asphalt and the modifier can be mixed more fully through the flow of asphalt and the impact force generated by the flow of asphalt. This can effectively solve the problem that the existing single stirring method is prone to the agglomeration of the modifier in the asphalt, resulting in the powdery particles of the modifier wrapped in the agglomerated mixture, which is easy to cause problems in the subsequent use of asphalt.

[0038] Among them, when the telescopic shaft 10 moves, it will also drive the return spring 11 to move. First, the return spring 11 can drive the telescopic shaft 10 to contract to avoid spreading too much modified material on a layer of asphalt material. On the other hand, the return spring 11 can stir the modified material when it moves, and can even crack and break the rigid material in the modified material to achieve the purpose of refining the modified material.

[0039] Embodiment 2:

[0040] like Figure 3 and Figure 5 As shown, the diameter of the movable plate 5 is larger than the diameter of the partition 3, and the bottom of the movable plate 5 is in contact with the top of the partition 3. An elliptical hole 15 is opened in the middle of the movable plate 5, and a scraper strip 16 is installed at the position of the elliptical hole 15 of the spiral roller shaft 8 through fasteners.

[0041] In this embodiment, based on the embodiment 1, when the spiral roller shaft 8 rotates, the scraper strip 16 thereon also rotates. When the scraper strip 16 rotates, it pushes the movable plate 5 to make an eccentric movement. At this time, the movable plate 5 and the circulation leakage hole 6 on the partition 3 will be misaligned. On the one hand, the asphalt material on the movable plate 5 can have enough time to receive the modified material. On the other hand, some soft raw materials can be cut off during the misalignment process, thereby achieving crushing, so that the asphalt material and the modified material can be fully mixed, thereby producing high-quality modified asphalt.

[0042] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
