Asphalt mixture processing mixer

Abstract

The present invention relates to the technical field of mixers, and specifically proposes an asphalt mixture processing mixer, comprising a mixing pot with a semicircular bottom, wherein circular plates with a fixed rod in the middle are installed on both sides of the inner wall of the mixing pot, and the center of the circular plate is located on the same horizontal line as the center of the semicircular bottom. The interior of the mixing pot is equipped with three groups of rotatable mixing components arranged in a circular array with the center of the circular plate. The present invention arranges three groups of mixing components, gear 1 and a ring gear, and regards the three groups of mixing components as a whole to rotate in the positive direction. The engagement of the ring gear and gear 1 causes each mixing shaft to rotate in the opposite direction to form three circular mixing areas. However, since the rotation direction of the mixing as a whole is opposite to the rotation direction of the mixing shaft, a complex mixing path can be formed, and the mixing coverage area is larger, reducing the mixing dead angle, and the raw materials near the mixing shaft will also move with the revolution of the mixing shaft, further reducing the mixing dead angle and providing an overall mixing effect.

Description

Technical Field

[0001] The invention relates to the technical field of mixers, and in particular provides an asphalt mixture processing mixer. Background Art

[0002] Asphalt mixing pot is one of the key equipment in asphalt mixture production. Its main structure includes the pot body and stirring device. The pot body is the main part of the asphalt mixing pot. It is generally made of high-quality heat-resistant steel and has good high temperature resistance and wear resistance. Its shape is usually cylindrical, and the bottom can be flat or hemispherical to adapt to different mixing needs. The stirring device is the core component for achieving material mixing. It is usually composed of a stirring shaft and stirring blades, and is driven to rotate by a motor and a reducer. Blades of different shapes are suitable for stirring different types of materials, which can make the materials produce complex motion trajectories in the pot body, thereby achieving sufficient mixing.

[0003] The stirring method of asphalt mixing pot is usually double-axis stirring. During the stirring process, the two shafts rotate in opposite directions, causing the material to produce a complex motion trajectory in the stirring chamber. The material will not only move in the axial and radial directions, but also form strong convection and shearing effects between the two shafts. This complex movement can effectively reduce the mixing dead angle. At the same time, the double-axis structure enables the mixing blades to cover a larger stirring space, which means that the double-axis mixer can mix the material more comprehensively during the stirring process, reducing the possibility of mixing dead angles due to insufficient stirring range.

[0004] However, since the positions of the dual shafts of the current asphalt mixing pot are fixed, the mixing range is the range covered by the revolution of the mixing blades with the mixing shaft as the center. There will be overlapping coverage space between the mixing blades of the dual shafts, which can effectively mix the asphalt near the mixing shaft. However, the mixing effect of the asphalt in the non-overlapping area near the two mixing shafts is relatively poor. Regardless of whether the bottom of the mixing pot is flat or hemispherical, due to the coverage range of the mixing blades, there are still some mixing dead angles from its edge to the bottom of the mixing pot, which will affect the mixing effect.

[0005] The mixing of asphalt includes two processes: dry mixing between aggregates and wet mixing between aggregates and asphalt. During wet mixing, the asphalt needs to be injected into the mixing pot in batches. Therefore, when the asphalt is injected into the mixing pot from top to bottom, the position of the mixing shaft is fixed, so the mixing blades may not be able to mix the injected asphalt immediately, affecting the mixing efficiency. In addition, asphalt itself is sticky, and some asphalt may carry aggregates and move to the mixing dead corner area, which also greatly affects the asphalt mixing effect. Summary of the Invention

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Figure 1 It is an asphalt mixture processing mixer, comprising a mixing pot 1 with a semi-circular bottom, the bottom of which is equipped with an openable and closable discharge valve (see Figure 2 ), the stirring pot 1 is placed in the working area through a support column welded at the bottom, and circular plates 2 with a fixing rod in the middle are installed on both sides of the inner wall of the stirring pot 1. The center of the circular plate 2 is on the same horizontal line as the center of the semicircular bottom, and the edge of the circular plate 2 can rest on the bottom of the inner wall of the stirring pot 1. The interior of the stirring pot 1 is equipped with three groups of rotatable stirring components arranged in a circular array with the circular plate 2 as the center. Example

[0036] like Figure 1 and Figure 5 As shown, the stirring assembly includes a plurality of axially assembled stirring shafts 3, which are fixedly connected by bolts. In this embodiment, the surface of each stirring shaft 3 is equipped with three stirring rods 4 in a spiral array, and the stirring rods 4 are of any shape. The surface of the stirring rod 4 is equipped with two stirring blades 5, and the inclination directions of the two stirring blades 5 are completely opposite. When the stirring shaft 3 rotates, the side edges of the stirring blades 5 can intermittently rest against the inner wall of the semicircular bottom of the stirring pot 1, and at the same time, the side edges of the stirring blades 5 can also intermittently contact the nearby surface of the stirring shaft 3.

[0037] like Figure 3 and Figure 4As shown, both sides of the mixing pot 1 are provided with through grooves 7 which are completely covered by the circular plate 2. The circular plate 2 is against the side wall of the mixing pot 1 to prevent the aggregate and asphalt from overflowing from the through groove 7 during the mixing process. The fixing rod on the circular plate 2 passes through the inside of the through groove 7. Protective covers are provided on both sides of the mixing pot 1. The fixing rod is installed inside the protective cover through a bearing to ensure that the fixing rod can stably drive the circular plate 2 to rotate. A reduction motor is provided outside the mixing pot 1 to be connected to the fixing rod for driving the rotation of the circular plate 2 (not shown in the figure). The ends of the two mixing shafts 3 located at both ends are fixed with a rotating shaft 8 by bolts. The end of the rotating shaft 8 movably passes through the circular plate 2 and extends to the inside of the protective cover. The rotating shaft 8 and the circular plate 2 are also connected and fixed by bearings.

[0038] The surface of the rotating shaft 8 on one side of the mixing pot 1 is equipped with a gear 9, and the side of the mixing pot 1 is equipped with a ring gear 10. The gear 9 is located on the inner side of the ring gear 10 and meshes with the ring gear 10. When the reduction motor drives the circular plate 2 to rotate, the circular plate 2 drives the three groups of stirring components to revolve around the axis of the circular plate 2. At this time, all the stirring blades 5 will mix the entire aggregate. Assuming that the rotation direction at this time is the positive direction, due to the meshing action of the ring gear 10 and the gear 9, the gear 9 will be reversed, then all the stirring shafts 3 will be reversed, thereby forming three stirring areas respectively, and the three areas are mixed respectively. The overall stirring and mixing are combined with the regional stirring and mixing, and the rotation direction is completely opposite. Each stirring blade 5 will form a complex movement path to improve the mixing effect. And since each stirring shaft 3 will revolve, in the stirring areas that do not overlap, the aggregate around the stirring shaft 3 will still move to different positions with the revolution of the stirring shaft 3, thereby achieving a better mixing effect.

[0039] Compared with the traditional dual-axis fixed mixing mode, the three-axis moving mixing mode enables the mixing blade 5 to contact the edge of the inner wall of the mixing pot 1, and the mixing shaft 3 drives the nearby aggregate to move, thereby increasing the mixing coverage range, reducing the mixing dead angle as much as possible, and ensuring the mixing effect.

[0040] In order to ensure the stable meshing of the ring gear 10 and the gear 9, the surface of the rotating shaft 8 on the other side of the stirring pot 1 is sleeved with a pulley 11, and any two adjacent groups of pulleys 11 are connected by multiple transmission belts 12. Since the long-term meshing of the gear 9 and the ring gear 10 during the transmission process will cause the teeth to wear, the pulley 11 and the transmission belt 12 are used for auxiliary transmission to improve the stability of the entire equipment.

[0041] like Figure 1 and Figure 6 As shown, the stirring pot 1 is provided with a transverse groove 13 on one side of the circular plate 2 in the direction of rotation. Figure 6The direction of the middle arrow is the direction of rotation of each stirring shaft 3, and the direction of rotation of the circular plate 2 is the opposite direction. A feeding head 14 is embedded in the inner wall of the transverse groove 13, and a plurality of inclined discharge troughs 6 are provided on the surface of the feeding head 14. The inclined direction of the discharge trough 6 is the tangential direction of the stirring blade 5 when it revolves. When the stirring blade 5 rotates, the outlet of the discharge trough 6 will be scraped to ensure that the asphalt can flow out smoothly from the inside of the discharge trough 6. The discharge trough 6 is arranged in an axial linear array along the stirring shaft 3. The discharge trough 6 is arranged in an axial linear array along the stirring shaft 3. An integral inclined frame 15 is provided on the feeding head 14. The discharge trough 6 is an inverted V-shape, and its bending portion is higher than the position of the discharge port and the feed port.

[0042] Pour asphalt into the interior of the inclined material frame 15. As the liquid level gradually rises until it reaches the bend, the asphalt will evenly flow out from the inside of each discharge trough 6 and slowly flow down along the bottom of the stirring pot 1. At a certain interval (depending on the rotation speed of the stirring shaft 3), the stirring blade 5 will move to the position of the discharge trough 6 to take away the asphalt and mix it with the aggregate. Compared with the traditional quantitative batch injection method, this method can continuously inject asphalt and can avoid the problem of large amounts of asphalt accumulating and bonding aggregates as much as possible, ensuring the effect of mixing aggregates and asphalt, while also improving the mixing efficiency.

[0043] like Figure 3 、 Figure 6-Figure 7 As shown, a support plate 16 for placing an inclined material frame 15 is welded to the outside of the stirring pot 1, and a guide block 17 with an isosceles trapezoidal cross-section is provided on the surface of the inclined material frame 15. In this embodiment, there are two groups of guide blocks 17. A guide groove 18 adapted to the guide block 17 is provided on the surface of the support plate 16. The guide block 17 is movably engaged in the inside of the guide groove 18. The surface assembly surface of the support plate 16 is provided with a fixing plate 20 with a threaded hole. A threaded rod 21 is threadedly installed on the surface of the fixing plate 20. A rotatable hinge joint is provided at the end of the threaded rod 21. An extrusion plate 19 is movably installed at the position of the hinge joint, and the extrusion plate 19 is against the surface of the inclined material frame 15.

[0044] During long-term use, the inside of the discharge chute 6 will inevitably become clogged. At this time, the feed head 14 needs to be replaced as a whole. The threaded rod 21 is rotated to make the extrusion plate 19 move away from the bevel frame 15 until the extrusion plate 19 is flush with the support plate 16. At this time, the entire bevel frame 15 can be removed, and a new bevel frame 15 can be installed. The installation can be done in reverse order. Example

[0045] like Figure 9 and Figure 10As shown, the stirring rod 4 is circular in shape, and the same surface is equipped with two stirring blades 5 with completely opposite inclination directions. A round rod 22 is movably passed through the middle of the stirring shaft 3, and the two ends of the round rod 22 are respectively equipped with a rotating plate 24 with a groove on the surface and a block 23 adapted to the shape of the groove. The shape of the block 23 can be non-circular, and the side of the rotating plate 24 is flush with the side of the end of the stirring shaft 3. When assembling adjacent stirring shafts 3, it is necessary to align the block 23 with the inside of the groove of the rotating plate 24. The middle part of the rotating shaft 8 at both ends is movably equipped with a connecting shaft 25, and the rotating plate 24 and the block 23 are embedded in the end of the connecting shaft 25, that is, the end of the connecting shaft 25 connected to the rotating plate 24 is provided with the same block 23, and the end of the connecting shaft 25 connected to the block 23 is provided with the same groove. When the stirring shaft 3 is assembled, all the internal round rods 22 can rotate simultaneously.

[0046] like Figure 10 and Figure 11 As shown, the interior of the stirring shaft 3 is equipped with a rotatable rotating rod 26 through a mounting seat, that is, the rotating rod 26 and the stirring shaft 3 will not produce relative displacement. Each stirring rod 4 corresponds to a rotating rod 26. The surfaces of the round rod 22 and the rotating rod 26 are equipped with mutually meshing gears 27. When the round rod 22 rotates, the rotating rod 26 is driven to rotate through the gear 27. The surfaces of the stirring rod 4 and the rotating rod 26 are equipped with mutually meshing bevel gears 28, thereby indirectly causing the stirring rod 4 to rotate. Figure 8 As shown, the end of the connecting shaft 25 extends to the outside of the rotating shaft 8 and is fixed to the surface of the fixed rod by a connecting rod 29, that is, the round rod 22 will not rotate. When the stirring shaft 3 rotates, the rotating rod 26 will revolve around the round rod 22. The engagement of the two gears 27 makes the rotating rod 26 rotate, and the engagement of the bevel gear 28 realizes the rotation of the stirring rod 4. As a result, the movement path of the stirring blade 5 will be more complicated, which can further improve the mixing effect.
