Description

Technical Field

[0001] The present invention relates to the technical field of recycled asphalt concrete processing, and in particular to green and environmentally friendly recycled asphalt concrete purification processing equipment. Background Art

[0002] Recycled asphalt concrete is an asphalt mixture that meets road performance requirements by excavating, recycling, crushing, and screening discarded old asphalt concrete, and then mixing it with some new aggregate and new asphalt in a certain proportion. It is used to pave the surface or base layer of the road, thereby reducing energy consumption and enhancing environmental protection by reusing asphalt and stone. The use of recycled asphalt concrete in road construction is of great significance in terms of technology, economy, and environment. The green and environmentally friendly recycled asphalt concrete purification equipment is used to screen the recycled and crushed recycled asphalt concrete to achieve purification of the recycled recycled asphalt concrete.

[0003] For example, the Chinese patent with the authorization announcement number CN217016783U and the authorization announcement date of 2022.07.22, and the name "A Green and Environmentally Friendly Regenerated Asphalt Concrete Purification Treatment Device", its specific structure includes a shell, the top of the shell is provided with a feeding port, the interior of the shell is provided with a crushing layer, a screening layer and a collection layer from top to bottom, the crushing layer includes a filter plate, the filter plate is connected to the inner wall of the shell, the filter plate is provided with filter holes, and a heater and a rotating roller located in the shell are also provided above the filter plate, the rotating roller is provided with crushing nails, and a constant speed motor is installed at one end of the rotating roller.

[0004] For example, the above-mentioned application is to crush, screen and purify the recycled asphalt concrete. The shortcoming of the existing technology including the above-mentioned application is that, at present, vibrating screens are mostly used for screening and purification of recycled asphalt concrete, and screening is performed by vertical vibration during the screening process. Since there is a mixture of granular materials of different masses (such as stone and asphalt granular materials) in the recycled asphalt concrete, the traditional vibrating screen has a poor screening efficiency when screening the mixed materials such as recycled asphalt concrete in a single manner, and the screening is carried out continuously in a flow-type manner. When screening the mixed material particles, lighter granular materials are prone to appear in the upper layer. Since the lower aggregate forms a bridging effect on the upper sieve holes, some of the lighter particles in the upper layer move along with the lower aggregate, affecting the screening effect.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1-9 The embodiment of the present invention provides a technical solution: a green and environmentally friendly recycled asphalt concrete purification treatment equipment, which is used to screen and purify asphalt concrete recovered by excavation and crushing, including an inclined conveying mechanism 1, and the conveying mechanism 1 is connected to a vibrating screening mechanism 3 through an elastic connecting member 2, that is, the vibrating screening mechanism 3 can vibrate on the conveying mechanism 1 through the elastic connecting member 2, wherein the vibrating screening mechanism 3 is installed above the conveying mechanism 1, and the vibrating screening mechanism 3 and the conveying mechanism 1 are parallel to each other and are also inclined, so that the material screened on the vibrating screening mechanism 3 can be vibrated under the action of gravity. The material is automatically screened at the bottom, and the vibrating screening mechanism 3 includes a screen frame 31. The screen frame 31 is composed of two parallel side plates connected by a fixed frame. A composite screen assembly 5 is slidingly arranged in the screen frame 31, and a vibration assembly 30 is arranged on the screen frame 31; the vibration assembly 30 is used to cooperate with the elastic connecting part 2 to drive the vibrating screening mechanism 3 to vibrate, wherein the vibration mode is up and down reciprocating vibration in the vertical direction. Optionally, the vibration assembly 30 is a vibration motor, which is used to provide a vibration power source for the screen frame 31. Furthermore, the vibration assembly 30 can also be a driving motor cooperated with an eccentric driving mechanism to drive other vibration driving mechanisms.

[0034] A composite screening mechanism 4 is also provided on the conveying mechanism 1, and the composite screening mechanism 4 is transmission-connected to the composite screen assembly 5. The composite screening mechanism 4 is arranged parallel to the vibrating screening mechanism 3 and is parallel to the vibrating screening mechanism 3. When the vibrating screening mechanism 3 performs vibrating screening, the composite screening mechanism 4 passively drives the composite screen assembly 5 to slide back and forth and intermittently blocks the aggregate sliding and screening on the composite screen assembly 5. That is, when the vibration component 30 cooperates with the elastic connecting part 2 to drive the vibration screening mechanism 3 to rise and fall and vibrate reciprocatingly, the composite screening mechanism 4 passively drives the composite screen component 5 in the vibration screening mechanism 3 to move linearly and reciprocatingly, and performs auxiliary screening to significantly improve the screening efficiency. At the same time, the composite screening mechanism 4 intermittently blocks the aggregates being slid and screened on the composite screen component 5, so that the composite screen component 5 has intermittent blank sections. When vibrating screening is performed, the lighter particles on the upper layer of the composite screen component 5 can be diffused to the blank sections on the composite screen component under the action of the linear reciprocating movement of the composite screen component 5, thereby achieving comprehensive screening of the mixed recycled asphalt concrete material, avoiding the lighter particles on the upper layer, and affecting the screening effect due to the bridging effect of the lower aggregate on the sieve holes of the composite screen component 5, which causes some of the lighter particles on the upper layer to move with the lower aggregate.

[0035] This embodiment provides a green and environmentally friendly recycled asphalt concrete purification and treatment equipment, by movably setting the composite screen assembly 5 in the vibrating screening mechanism 3, and arranging the composite screening mechanism 4 to be transmission-connected with the composite screen assembly 5, so that when the vibrating screening mechanism 3 performs vibrating screening, the composite screening mechanism 4 passively drives the composite screen assembly 5 in the vibrating screening mechanism 3 to move linearly back and forth, and performs auxiliary screening to significantly improve the screening efficiency. At the same time, the composite screening mechanism 4 intermittently blocks the aggregate slidingly screened on the composite screen assembly 5, so that the composite screen assembly 5 has intermittent blank sections. When vibrating screening is performed, the lighter granular material on the upper layer of the composite screen assembly 5 can be diffused to the blank section on the composite screen assembly under the action of the linear reciprocating movement of the composite screen assembly 5, thereby achieving comprehensive screening and treatment of the mixed recycled asphalt concrete material.

[0036] In another embodiment provided by the present invention, the composite screen assembly 5 includes two screen mechanisms 51 that are arranged in parallel and sliding in the screen frame 31. The two screen mechanisms 51 are arranged in parallel and sliding in the screen frame 31 in an upper and lower manner. The screen hole diameter of the upper screen mechanism 51 is larger than the screen hole diameter of the lower screen mechanism 51, so that the recycled asphalt concrete material is double-screened by the upper screen mechanism 51 cooperating with the lower screen mechanism 51, and a linkage adjustment mechanism 52 is arranged between the two screen mechanisms 51. The composite screening mechanism 4 is transmission-connected to the upper screen mechanism 51. When the composite screening mechanism 4 passively drives the composite screen assembly 5 to slide back and forth, the linkage adjustment mechanism 52 passively drives the lower screen mechanism 51 to move back and forth in the opposite direction. That is, by arranging a linkage adjustment mechanism 52 between the two screen mechanisms 51, when the composite screening mechanism 4 drives the upper screen mechanism 51 to move along one end of its length direction, the linkage adjustment mechanism 52 drives the lower screen mechanism 51 to move along the other end of the air field direction, so that the upper screen mechanism 51 and the lower screen mechanism 51 move back and forth in opposite directions, so that the aggregate screened by the upper screen mechanism 51 can be evenly screened on the lower screen mechanism 51 when the aggregate is diffused during throwing. The upper screen mechanism 51 and the lower screen mechanism 51 are necessarily in a relatively static state for material screening, which significantly improves the screening uniformity of the lower screen mechanism 51 and further improves the screening effect.

[0037] In another embodiment provided by the present invention, two groups of linkage adjustment mechanisms 52 are provided, and the two groups of linkage adjustment mechanisms 52 are symmetrically arranged on the two side walls inside the screen frame 31, wherein the linkage adjustment mechanism 52 includes a rotating connecting seat 521, the rotating connecting seat 521 is rotatably connected to the inner wall of the screen frame 31, and two groups of telescopic adjustment rods 522 are symmetrically slidably connected to the rotating connecting seat 521, and the ends of the two groups of telescopic adjustment rods 522 are respectively rotatably connected to the upper and lower sides of the screen mechanism 51 through a hinge seat 523. The linkage adjustment mechanism 52 passively drives the lower screen mechanism 51 and the upper screen mechanism 51 to move back and forth in the opposite direction. Specifically, when the upper screen mechanism 51 moves along one side of its length direction under the driving action of the composite screening mechanism 4, the upper screen mechanism 51 drives the rotating connecting seat 521 to rotate through the hinge seat 523 in cooperation with the telescopic adjustment rod 522, and the telescopic adjustment rod 522 on the other side of the rotating connecting seat 521 cooperates with the hinge seat 523 to drive the lower screen mechanism 51 to move linearly in the opposite direction. In this way, when the upper screen mechanism 51 moves back and forth linearly, under the drive of the linkage adjustment mechanism 52, the lower screen mechanism 51 maintains reciprocating movement in the opposite direction of the upper screen mechanism 51.

[0038] In another embodiment provided by the present invention, the outlet end of the screen frame 31 is connected to a first discharge interface 32 and a second discharge interface 33 for cooperating with two screen mechanisms 51 to discharge materials, and the outlet directions of the first discharge interface 32 and the second discharge interface 33 are respectively directed to both sides, and the screen mechanism 51 includes a screen frame 511, a steel mesh frame 512 is provided in the screen frame 511, and a compensation connecting plate 513 is integrally fixed to the tail end of the screen frame 511, and the compensation connecting plate 513 is slidably overlapped on the first discharge interface 32. By installing the first discharge interface 32 and the second discharge interface 33 at the outlet end of the screen frame 31, the outlets of the first discharge interface 32 and the second discharge interface 33 are located on both sides of the conveying mechanism 1, the first discharge interface 32 is docked with the upper screen mechanism 51, and the second discharge interface 33 is docked with the lower screen mechanism 51, thereby realizing separate discharge of the aggregates on the two layers of screen mechanisms 51, and further, the tail ends of the screen frames 511 in the two layers of screen mechanisms 51 are provided with compensation connecting plates 513, and the compensation connecting plates 513 in the two layers of screen mechanisms 51 are correspondingly slidably overlapped on the first discharge interface 32 and the second discharge interface 33, so that the screen mechanism 51 can always maintain docking and feeding with the first discharge interface 32 and the second discharge interface 33 through the compensation connecting plate 513 during reciprocating linear movement, thereby improving the stability of discharge.

[0039] In another embodiment provided by the present invention, the compound screening mechanism 4 includes two adjusting side frames 41, which are symmetrically fixed to the conveying mechanism 1 through brackets, and the adjusting side frames 41 are located above the vibrating screening mechanism 3, and the distance between the adjusting side frames 41 and the vibrating screening mechanism 3 is greater than the stroke length of the reciprocating lifting vibration of the vibrating screening mechanism 3, thereby avoiding interference with the vibration of the vibrating screening mechanism 3. A plurality of adjusting arms 42 are equidistantly connected to the adjusting side frames 41 for rotation, and the tail ends of the adjusting arms 42 are rotatably connected to the compound screen assembly 5 through an articulated frame 43. Since the adjusting side frames 41 are fixed to the conveying mechanism 1 through brackets, when the vibrating screening mechanism 3 vibrates reciprocatingly, the vibrating screening mechanism 3 synchronously drives the compound screen assembly 5 thereon to rise and fall synchronously. Vibration, since the composite screen assembly 5 is slidingly arranged on the vibrating screening mechanism 3, when the vibrating screening mechanism 3 drives the composite screen assembly 5 to rise in the vibration stroke, multiple adjusting arms 42 drive the composite screen assembly 5 to move to one side, and when the vibrating screening mechanism 3 drives the composite screen assembly 5 to descend in the vibration stroke, multiple adjusting arms 42 drive the composite screen assembly 5 to move to the other side, and so on, the composite screen assembly 5 is driven to move reciprocating linearly, and the composite screen assembly 5 is subjected to reciprocating lifting vibration and reciprocating linear sliding dual-drive combined vibration for screening, which significantly improves the screening effect. Furthermore, multiple connecting frames 44 are symmetrically fixed on the two adjusting side frames 41, and a material unloading adjustment frame 45 is connected between the bottom ends of the two relative connecting frames 44. The connecting frame 44 is composed of a sleeve and an adjusting rod slidably embedded in the bottom end of the sleeve, and a spring is provided between the adjusting rod and the sleeve. The elastic force of the spring is used to drive the adjusting rod to protrude to the outside of the sleeve, and the top of the sleeve is fixed to the adjusting side frame 41. A blanking adjustment stop frame 45 is connected between the bottom ends of the adjusting rods in the two connecting frames 44 opposite to each other along the length direction of the vibrating screening mechanism 3. By setting the connecting frame 44 to be composed of a sleeve and an adjusting rod, and cooperating with the spring to elastically support the adjusting rod, the vibrating screening mechanism 3 drives the composite screen assembly 5 to synchronously perform the lifting and vibrating stroke. The blanking adjustment stop frame 45 is located at the rear end of the rising stroke and the front end of the falling stroke. The frame 45 is attached to the surface of the composite screen assembly 5 under the action of the connecting frame 44, realizing intermittent material discharge blocking, so that the composite screen assembly 5 has intermittent blank sections. When vibrating screening is performed, the lighter particles on the upper layer of the composite screen assembly 5 can be diffused to the blank sections on the composite screen assembly under the action of the linear reciprocating movement of the composite screen assembly 5, thereby realizing comprehensive screening of the mixed recycled asphalt concrete material, avoiding the lighter particles on the upper layer, and affecting the screening effect due to the bridging effect of the lower aggregate on the sieve holes of the composite screen assembly 5, causing some of the lighter particles on the upper layer to move along with the lower aggregate.

[0040] In another embodiment provided by the present invention, further, the steel grid 512 includes a plurality of longitudinal steel frames 5121 equidistantly arranged along the length direction of the screen frame 511, and a plurality of transverse steel frames 5122 equidistantly arranged along the width direction of the screen frame 511, and a sieve hole is formed between the plurality of longitudinal steel frames 5121 and the transverse steel frames 5122, the tail end of the longitudinal steel frame 5121 extends to the outside of the steel grid 512 and is fixedly sleeved with an adjusting column 5123, the circumference of the adjusting column 5123 is provided with a spiral adjusting groove 5124, the bottom of the first discharge interface 32 is connected to the limiting bracket 321, and the bottom of the limiting bracket 321 is provided with an adjusting protrusion The adjusting convex part is embedded in the spiral adjusting groove 5124. When the screen mechanism 51 moves back and forth, it synchronously drives the steel grid 512 thereon to move back and forth. The longitudinal steel frame 5121 in the steel grid 512 is rotated. At this time, when the longitudinal steel frame 5121 moves linearly synchronously with the steel grid 512, the adjusting convex part on the limiting bracket 321 cooperates with the spiral adjusting groove 5124 to drive the adjusting column 5123 to rotate, and the adjusting column 5123 drives the longitudinal steel frame 5121 to rotate back and forth, thereby passively driving the longitudinal steel frame 5121 to rotate back and forth during screening, thereby reducing the situation where the screened aggregate blocks the screen holes, further improving the screening effect.

The first connecting seat 21 is fixed on the conveying mechanism 1, and the second connecting seat 22 is fixed on the outer wall of the vibrating screening mechanism 3. The positions of the first connecting seat 21 and the second connecting seat 22 correspond to each other up and down. A through hole is opened on the second connecting seat 22 for use with the limiting rod 23. A plurality of limiting rods 23 are vertically fixed on the first connecting seat 21. The limiting rods 23 pass through the through holes to realize movable limiting of the first connecting seat 21 and the second connecting seat 22. A support spring 24 is sleeved on the limiting rod 23, and the two ends of the support spring 24 respectively abut against the first connecting seat 21 and the second connecting seat 22 to realize elastic support.

[0042] In another embodiment provided by the present invention, the conveying mechanism 1 includes a conveying frame 11, a support base 12 is provided at the bottom of the conveying frame 11, and a conveyor belt 14 is rotatably provided on the conveying frame 11 via rotating rollers 13. Specifically, rotating rollers 13 are symmetrically rotated at both ends of the conveying frame 11, and the conveyor belt 14 is sleeved between the two rotating rollers 13. A drive motor is provided on the outside of the conveying frame 11, and the drive motor is in transmission connection with one of the rotating rollers 13. The drive motor drives the rotating roller 13 to rotate, and the rotating roller 13 drives the conveyor belt 14 to rotate, thereby conveying the aggregate screened by the lower screen mechanism 51 via the conveyor belt 14.

[0043] In another embodiment provided by the present invention, a silo 6 is further fixed to the conveying mechanism 1 via a bracket. A feed interface 61 is provided at the bottom of the silo 6, and the feed interface 61 faces the inlet of the vibrating screening mechanism 3. Furthermore, left and right feed components are provided in the feed interface 61, and a docking mechanism is provided at a position opposite to the feed interface 61 at the inlet of the screen frame 31. When the vibrating screening mechanism 3 performs vibratory screening, the docking mechanism passively drives the feed component in the feed interface 61 to break up and discard the aggregate conveyed by the feed interface 61, thereby preventing aggregate consolidation from affecting the screening effect and further improving the screening effect.

[0044] The unloading component includes a rotating shaft 62 rotatably arranged in the feeding interface 61, and the circumferential surface of the rotating shaft 62 is evenly provided with shift rods. The two ends of the rotating shaft 62 pass through the outside of the feeding interface 61 and are fixedly sleeved with an adjusting gear sleeve 64 through a one-way bearing 63. The docking mechanism includes a docking sleeve 34 integrally formed at the inlet position of the screen frame 31, and strip openings 35 are opened on both sides of the docking sleeve 34, and adjusting gear racks 36 used to cooperate with the adjusting gear sleeve 64 are provided on both sides of the docking sleeve 34, and the two adjusting gear racks 36 are staggered and distributed on both sides of the strip opening 35 of the docking sleeve 34. When the feeding interface 61 at the bottom of the silo 6 is docked with the docking mechanism for feeding, the feeding interface 61 is deeply inserted into the docking sleeve 34, and both ends of the rotating shaft 62 in the feeding interface 61 extend to the outside through the strip openings 35 on both sides of the docking sleeve 34, and the adjusting gear sleeves 64 connected at both ends of the rotating shaft 62 are respectively engaged with the adjusting gear racks 36 on both sides of the docking sleeve 34. Since the adjusting gear sleeve 64 is connected to the rotating shaft 62 through a one-way bearing 63, the one-way bearing 63 is a bearing that can rotate freely in one direction and is locked in the other direction, so that when the screen frame 31 rises, the adjusting gear sleeve 64 at one end cooperates with the adjusting gear rack 36 6 drives the rotating shaft 62 to rotate in more than one direction, and the adjusting gear sleeve 64 at the other end is in an idling state. When the screen frame 31 descends, the adjusting gear sleeve 64 at the other end cooperates with the adjusting gear rack 36 to drive the rotating shaft 62 to rotate in the same direction. At this time, the adjusting gear sleeve 64 at one end is in an idling state, thereby realizing the passive driving of the rotating shaft 62 to always rotate in the same direction, and realizing the aggregate delivered to the feeding interface 61 by the rotating shaft 62 in cooperation with the shifting rod to be broken up and thrown, while avoiding the two-way reciprocating rotation of the rotating shaft 62 affecting the stability of the discharge amount, and causing the discharge to be blocked, affecting the stability of the passive drive.
