Description

Technical Field

[0001] This utility model relates to the field of lignin-modified asphalt mixing technology, specifically to a lignin-modified asphalt mixing device with heating function. Background Technology

[0002] A lignin-modified asphalt mixing unit is a device used to mix lignin with asphalt for modification. Lignin is one of the main components of plant cell walls and possesses excellent chemical and physical properties, especially in improving the performance of asphalt. As an environmentally friendly and renewable modifying material, lignin has been widely researched and applied. Lignin and asphalt themselves have different physical properties. Asphalt is a highly viscous, oily liquid, while lignin is a complex organic polymer with strong hydrophilicity and low thermal stability. Therefore, during the mixing process, lignin needs to be uniformly dispersed in the asphalt to avoid agglomeration or precipitation.

[0003] While existing lignin-modified asphalt mixing devices can effectively mix lignin and asphalt, in practical applications, the heating system is located inside the mixing tank. This means that during mixing, the lignin and asphalt adhering to the inner wall of the mixing tank cannot be mixed. Over time, the lignin is prone to thermal degradation due to prolonged exposure to high temperatures, and the viscosity of the asphalt decreases due to prolonged heating, resulting in asphalt adhering to the inner wall of the mixing tank, making cleaning difficult and inconvenient to use.

[0004] Therefore, we propose a lignin-modified asphalt mixing device with heating function to solve the problems mentioned above. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-3A lignin-modified asphalt mixing device with heating function includes a mixing structure 1. The mixing structure 1 includes a mixing drum 16 and connecting strips 15 installed on both sides of the mixing drum 16. An adjusting member 11 is installed at one end of the connecting strip 15. An upper cover plate 12 is installed at the top of the two sets of adjusting members 11, and the upper cover plate 12 is located at the upper end of the mixing drum 16. An operating member 13 is installed at the bottom end of the upper cover plate 12, and an internal stirring member 14 is installed at the middle of the bottom end of the operating member 13.

[0024] The operating component 13 includes a rubber cylinder 131 and a suction tube 132 opened inside the rubber cylinder 131. A T-shaped rod 121 is movably installed at the top center of the upper cover plate 12. A gear A122 is installed on the lower outer surface of the T-shaped rod 121. A drive unit 124 is installed at the top of the upper cover plate 12 and on one side of the T-shaped rod 121. A rotating shaft 125 is installed at the output end of the drive unit 124. A gear B126 is installed on the lower outer surface of the rotating shaft 125. The gear B126 meshes with the gear A122. A wire hole 123 is opened through the middle end of the T-shaped rod 121.

[0025] The internal stirring component 14 includes a rotating cylinder 141 and a heating tube 135 installed inside the rotating cylinder 141. The rotating cylinder 141 is installed at the bottom end of the gear A122. A heat transfer plate 142 is installed laterally on the lower outer surface of the rotating cylinder 141. An outer stirring plate 143 and an inner stirring plate 144 are installed at the top of the heat transfer plate 142. The connecting wire of the heating tube 135 can be connected to an external power source through the wire hole 123.

[0026] The adjusting component 11 includes a fixed cylinder 111 and an inner bottom groove 112 formed inside the top of the fixed cylinder 111. A cylinder 113 is installed at the bottom of the inner bottom groove 112. A movable cylinder 114 is installed on one side of the bottom of the upper cover plate 12. An inner top groove 115 is formed inside the bottom of the movable cylinder 114. The movable end of the cylinder 113 is installed at the top of the inner top groove 115. The cylinder 113 is used to control the position and height of the upper cover plate 12, the operating component 13 and the inner stirring component 14.

[0027] In this embodiment: lignin and asphalt are poured into the interior of the mixing drum 16. The cylinder 113 retracts, and the moving drum 114 moves downward, causing the upper cover plate 12 to move along with it. The inner stirring component 14 is inserted into the bottom of the mixing drum 16, and the rubber cylinder 131 is inserted into the upper end of the mixing drum 16. The single-machine 124 is driven to operate, and the rotating shaft 125 rotates, causing the rotating shaft 125 and gear A122 to rotate. The rotating drum 141, installed at the bottom of gear A122, drives the heat transfer plate 142, the outer stirring plate 143, and the inner stirring plate 144 to rotate and stir inside the mixing drum 16. The wire supplies power to the heating tube 135 inside the rotating drum 141 through the wire hole 123. The heating tube 135 heats the tube, and the heat is transferred through the rotating drum 141 to the heat transfer plate 142, the outer stirring plate 143, and the inner stirring plate 144. In step 4, the heated rotating cylinder 141, heat transfer plate 142, outer stirring plate 143, and inner stirring plate 144 mix and stir the lignin and asphalt inside the mixing cylinder 16. Since the outer surfaces of the rotating cylinder 141, heat transfer plate 142, outer stirring plate 143, and inner stirring plate 144 are all coated with ceramic coating 145, the lignin and asphalt are prevented from adhering to the outer surface of the inner stirring component 14. At the same time, the inner stirring component 14 can thoroughly mix and stir the lignin and asphalt inside the mixing cylinder 16. The outer wall of the outer stirring plate 143 contacts the inner wall of the mixing cylinder 16, reducing the adhesion of lignin and asphalt to the inner wall of the mixing cylinder 16. When the upper cover plate 12, operating component 13, and inner stirring component 14 move upward, the ceramic coating 145 prevents the lignin and asphalt from adhering to the outer surface of the inner stirring component 14.

[0028] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 2 and Figure 4 The outer wall of the rubber cylinder 131 contacts the inner wall of the mixing cylinder 16. A sealing ring 134 is installed at the bottom of the inner part of the rubber cylinder 131, and the sealing ring 134 seals the space between the rotating cylinder 141 and the rubber cylinder 131.

[0029] An air pump 127 is installed at the top of the top cover plate 12. A suction pipe 132 is installed through the inside of the rubber cylinder 131. One end of the suction pipe 132 is connected to the suction end of the air pump 127. The air pump 127 extracts the odor generated inside the mixing drum 16 through the suction pipe 132.

[0030] A T-shaped tube 128 is installed through the interior of the T-shaped rod 121 and the rubber cylinder 131. A dustproof net 129 is installed at the upper end of the interior of the T-shaped tube 128. A one-way valve 133 is installed at the lower end of the dustproof net 129 inside the T-shaped tube 128. The distance between the one-way valve 133 and the extraction tube 132 is located on both sides of the sealing ring 134 to prevent the air entering the mixing drum 16 from being immediately extracted.

[0031] The outer surfaces of the rotating cylinder 141, heat transfer plate 142, stirring outer page 143 and stirring inner page 144 are all coated with ceramic coating 145. The ceramic coating 145 prevents lignin and asphalt from adhering to the outer surface of the inner stirring component 14.

[0032] In this embodiment: when the internal stirring component 14 mixes and stirs the lignin and asphalt, the vacuum pump 127 operates. The odor generated during the mixing of the mixing drum 16 is extracted by the vacuum pump 127 through the extraction pipe 132. The gas is collected in a collection bottle. As the gas inside the mixing drum 16 is extracted, the outside air passes through the dustproof net 129, which blocks impurities in the air. The one-way valve 133 controls the airflow in one direction to prevent the leakage of odorous gas.

[0033] Working principle: Lignin and asphalt are poured into the mixing drum 16, driving the single unit 124 to operate. The heat transfer plate 142, the outer mixing plate 143, and the inner mixing plate 144 rotate and stir inside the mixing drum 16. The electric wire supplies power to the heating tube 135 inside the rotating drum 141 through the wire hole 123. The heating tube 135 heats the mixture, and the heat is transferred through the rotating drum 141 to the heat transfer plate 142, the outer mixing plate 143, and the inner mixing plate 144 to heat, mix, and stir the lignin and asphalt inside the mixing drum 16. The outer wall of the outer mixing plate 143 contacts the inner wall of the mixing drum 16 to reduce the adhesion of lignin and asphalt to the inner wall of the mixing drum 16. The ceramic coating 145 is provided to prevent lignin and asphalt from adhering to the outer surface of the inner mixing component 14.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
