Description

Technical Field

[0001] The invention relates to the technical field of construction waste recycling and treatment, in particular to a processing device based on construction waste collaborative recycling micro powder. Background Art

[0002] The processing of co-regenerated micro-powder of construction waste is the process of converting construction waste into micro-powder materials. The purpose is to convert these wastes into valuable building materials, which can be applied to concrete, mortar, cement and other construction fields to achieve the goal of resource utilization. This processing process can not only reduce environmental pollution, but also save raw material resources. Specifically, it refers to the refining and crushing of different types of construction waste (such as waste concrete, waste bricks, waste stones, steel slag, waste glass, etc.) into micro-powder and mixing them together, improving their physical and chemical properties under the interaction, and achieving the improvement of comprehensive performance. The overall processing flow usually includes crushing, pulverizing, mixing, drying and other steps, among which crushing and mixing are the key links.

[0003] Existing crushing and mixing processes usually adopt a multi-stage crushing and final mixing method. Due to the differences in the physical properties, composition and processing requirements of different materials in construction waste, such as the common characteristics of waste concrete, waste bricks and waste stones are high hardness and strong wear resistance; steel slag has high density and hardness; waste glass has high brittleness and low hardness; the current fine crushing processing usually crushes different materials separately, and it is necessary to repeat the fine crushing steps many times. In addition, the conversion of different materials between equipment requires additional conveying auxiliary equipment for transfer, which leads to an extension of the processing cycle and increases the loss of materials during the transportation process during processing.

[0004] And because crushing and mixing are two independent steps, after crushing, the powders of different materials need to be sent to the mixing equipment for overall mixing. Mixing a large number of materials takes a long time and is prone to incomplete mixing. Summary of the invention

[0005] The present invention provides a processing device based on the coordinated regeneration of micro-powder from construction waste, which solves the problem that the existing crushing and mixing process usually adopts a multi-stage crushing and final mixing method in sequence. Since the physical properties, components and processing requirements of different materials in construction waste are quite different, different materials need to be crushed separately, and the crushing process needs to be repeated many times. This step-by-step processing method leads to the need for additional conveying equipment for conversion between different materials, which increases the processing cycle and aggravates material loss. In addition, since crushing and mixing are two independent steps, the micro-powder needs to be sent to the mixing equipment for overall mixing after the crushing is completed. When processing a large amount of materials, the mixing process is not only time-consuming, but also prone to incomplete mixing, affecting the quality and uniformity of the final regenerated micro-powder.

[0006] The present invention provides a processing device based on the coordinated regeneration of micro-powder from construction waste, comprising an upper open and rectangular work box and two rotating shafts symmetrically distributed and rotatably connected between the front and rear cavity walls of the work box, a driving part for driving the two rotating shafts to rotate in opposite directions is arranged at the rear of the work box, and a coordinated integrated mechanism for finely crushing and mixing different types of construction waste at the same time so as to quickly prepare regenerated micro-powder is arranged between the rotating shaft and the work box, the coordinated integrated mechanism comprises two crushing rollers respectively sleeved and fixed on the outside of the rotating shaft, two guide barrels symmetrically distributed and V-shaped and fixedly connected between the front and rear cavity walls of the work box and corresponding to the crushing rollers, the lower part of the guide barrel abuts against and fits on the outer wall of the corresponding crushing roller, and the guide barrels are equidistant A plurality of material guide grooves are provided which are perpendicular to the axis of the crushing roller and are distributed along the axis of the crushing roller.

A plurality of material conveying pipes which are corresponding to and connected to the material guide groove are equidistantly fixedly connected to the upper end face of the material guide cylinder along the axial direction of the crushing roller. A push plate is slidably connected in the material guide groove. Two pushing units for pushing the push plate to slide in the material guide groove to push the construction waste to be pushed onto the crushing roller for fine crushing are symmetrically arranged on the upper end face of the working box. A diversion mechanism for screening and re-crushing the finely crushed construction waste is arranged between the front and rear cavity walls of the working box and directly below the two crushing rollers.

[0007] In a possible implementation, the pushing unit includes a support plate fixedly connected to the upper end surface of the working box, a hydraulic telescopic cylinder is provided on the side of the support plate close to the middle of the working box, the telescopic end of the hydraulic telescopic cylinder is fixedly connected to a strip mounting plate, and a plurality of push rod groups corresponding to the push plate are fixedly connected at equal intervals on the side of the strip mounting plate close to the material guide cylinder, and the lower end of the push rod group is fixedly connected to the upper side of the push plate corresponding to it.

[0008] In one possible implementation, the diversion mechanism includes a material receiving platform, an extrusion bar, a rectangular frame and an inverted V-shaped screen. Two material receiving platforms are fixedly connected between the front and rear cavity walls of the working box, and are respectively located directly below the crushing rollers and are symmetrically distributed on the left and right. The upper surface of the material receiving platform is fixedly connected with an extrusion bar that contacts the outer wall of the crushing roller and has a trapezoidal vertical cross-section. The front and rear cavity walls of the working box are slidably connected to the rectangular frame through a reciprocating electric telescopic column. The front and rear opposite sides of the rectangular frame are fixedly connected with an inverted V-shaped screen located directly below the two crushing rollers through a connecting column, and the inverted V-shaped screen is slidably connected to the opposite sides of the two material receiving platforms.

[0009] In a possible implementation, the driving unit includes a driving motor fixedly connected to the rear end surface of the working box through a fixing frame, the output shaft of the driving motor is fixedly connected to the rear end of one of the rotating shafts, and the outsides of the two rotating shafts are fixedly connected with mutually meshing gear rings.

[0010] In one possible implementation, a material control unit is provided between the push rod group and the material delivery pipe, and the material control unit includes a valve plate slidably connected to the right wall plate of the material delivery pipe and an arc-shaped elastic sheet fixedly connected to the left cavity wall of the material delivery pipe and located below the valve plate; an L-shaped shift rod is fixedly connected to the right side of the valve plate; a limit spring is fixedly connected between the L-shaped shift rod and the material delivery pipe; and a push frame cooperating with the L-shaped shift rod is fixedly connected to the upper part of the push rod group.

[0015] In a possible implementation, the left and right cavity walls of the working box are in an inclined state gradually approaching the middle of the cavity bottom from top to bottom.

[0016] It can be seen from the above technical solutions that the present invention has the following advantages:

[0017] In the present invention, different materials in the construction waste are placed into a plurality of equally spaced material guide channels and pushed to collide with the outside of a crushing roller, so that different materials in the construction waste can be simultaneously finely crushed, avoiding the process of multiple crushing and equipment conversion in traditional processes, significantly shortening the processing cycle, and reducing the loss of materials during the processing.

[0018] In the present invention, multiple refinement and crushing are achieved by passing the construction waste respectively between the crushing roller and the crushing tooth seat, between the two crushing rollers, and between the crushing roller and the extrusion bar, which can more efficiently process different materials into fine particles and ensure a more uniform particle size distribution.

[0019] In the present invention, the arrangement design of the material guide cylinder and the crushing roller can also drive the finely crushed powder to mix together during the crushing process. Different types of materials in the construction waste can be mixed during the crushing process. The materials are already in a dynamic mixing state at each crushing stage, ensuring that different materials can be quickly and evenly mixed together after crushing, thereby improving the comprehensive performance of the recycled micropowder.

[0020] In the present invention, the receiving table, the extrusion bars, the inverted V-shaped screen and the crushing roller in the diversion mechanism cooperate with each other to screen the crushed construction waste, and at the same time, some of the incompletely crushed materials are crushed again, ensuring that the materials are more evenly and thoroughly refined, and further improving the uniformity and particle size consistency of the recycled micropowder.

[0035] See also Figure 1 , Figure 3 , Figure 4 and Fig. 9 In this embodiment, the cooperative integrated mechanism 4 includes two crushing rollers 41 respectively sleeved and fixed on the outside of the rotating shaft 2, two guide cylinders 42 symmetrically and V-shapedly distributed and fixedly connected between the front and rear cavity walls of the working box 1 and corresponding to the crushing rollers 41, the lower part of the guide cylinder 42 abuts against and fits on the outer wall of the crushing roller 41 corresponding to it, and the guide cylinder 42 is equidistantly provided with a plurality of guide grooves 43 running perpendicular to the axis of the crushing roller 41, and the guide grooves 43 are distributed along the axis of the crushing roller 41, and the lower part of the upper side wall plate of the guide cylinder 42 is equidistantly embedded and fixedly connected with a plurality of guide grooves 43 respectively located in the guide grooves 43 A crushing tooth seat 44 is located at the position and is used to cooperate with the crushing roller 41. The upper end surface of the guide cylinder 42 is fixedly connected with a plurality of conveying pipes 45 corresponding to and connected to the guide channel 43 at equal distances along the axial direction of the crushing roller 41. A push plate 46 is slidably connected in the guide channel 43. Two pushing units 47 are symmetrically arranged on the upper end surface of the working box 1 for pushing the push plate 46 to slide in the guide channel 43 to push the construction waste to the crushing roller 41 for fine crushing. A mask 7 for covering and limiting the construction waste being crushed is fixedly connected between the front and rear cavity walls of the working box 1 and directly above the crushing roller 41.

[0036] See also Figure 3 and Figure 4The pushing unit 47 includes a support plate 471 fixedly connected to the upper end surface of the working box 1, a hydraulic telescopic cylinder 472 is arranged on the side of the support plate 471 close to the middle of the working box 1, and a strip mounting plate 473 is fixedly connected to the telescopic end of the hydraulic telescopic cylinder 472, and a plurality of push rod groups 474 corresponding to the push plate 46 are fixedly connected at equal intervals on the side of the strip mounting plate 473 close to the material guide cylinder 42, and the lower end of the push rod group 474 is fixedly connected to the upper side of the push plate 46 corresponding to it.

[0037] See also Figure 4 , Figure 5 and Figure 6 A material control unit 6 is commonly provided between the push rod group 474 and the feed pipe 45. The material control unit 6 includes a valve plate 61 which is slidably connected to the right wall plate of the feed pipe 45 and an arc-shaped elastic sheet 62 which is fixedly connected to the left cavity wall of the feed pipe 45 and is located below the valve plate 61. An L-shaped lever 63 is fixedly connected to the right side of the valve plate 61. A limit spring 64 is commonly fixedly connected between the L-shaped lever 63 and the feed pipe 45. A push frame 65 which cooperates with the L-shaped lever 63 is fixedly connected to the upper part of the push rod group 474.

[0038] First, the driving motor 31 is controlled to run and drive the rotating shaft 2 connected thereto to rotate, and the rotating shaft 2 then drives the gear ring 32 to rotate, and the gear ring 32 then drives another rotating shaft 2 to rotate through another gear ring 32, and the two rotating shafts 2 then respectively drive the crushing rollers 41 to rotate, and the two crushing rollers 41 rotate in opposite directions. At this time, the hydraulic telescopic cylinder 472 is controlled to shrink to the shortest state, and the hydraulic telescopic cylinder 472 drives the push rod group 474 to move obliquely upward to the highest position, and the push rod group 474 then drives the push frame 65 to contact the L-shaped lever 63, and drives the L-shaped lever 63 to move upward, and the L-shaped lever 63 then pulls the valve plate 61 to move upward, so that the feed pipe 45 and the material guide channel 43 are in a connected state.

[0039] Then, different kinds of construction waste that have been broken into blocks are respectively introduced into the feed pipe 45, and the construction waste then enters the material guide chute 43 through the feed pipe 45. When the construction waste entering the material guide chute 43 reaches the required amount, the external construction waste introduced into the feed pipe 45 is stopped, and the construction waste in the feed pipe 45 continues to move downward until it completely enters the material guide chute 43. At this time, the material level of the construction waste in the material guide chute 43 does not exceed the connecting position between the material guide chute 45 and the feed pipe 45. Then, the hydraulic telescopic cylinder 472 is controlled to extend and push the push rod group 474 downward, and the push rod group 474 then pushes the push plate 46 downward, and the push plate 46 then pushes downward until the construction waste in the material guide chute 43 moves downward. (The push rod group 474 During the initial downward movement, the push rack 65 is driven to move downward synchronously. When the push rack 65 moves downward, the L-shaped lever 63 is gradually stopped. Then the limit spring 64 in the stretched state is reset and contracts to pull the L-shaped lever 63 to move downward gradually. The L-shaped lever 63 then drives the valve plate 61 to be gradually inserted into the feed pipe 45 until the lower part of the valve plate 61 touches the arc-shaped elastic sheet 62, cutting off the connection between the feed pipe 45 and the material guide channel 43. The building materials at the bottom of the material guide channel 43 will be pressed by the push plate 46 to fit the outer wall of the rotating crushing roller 41. The crushing roller 41 drives the construction waste to move upward toward the gap between the crushing roller 41 and the crushing tooth seat 44, and the crushing roller 41 and the crushing tooth seat 44 cooperate with each other to crush the construction materials.

[0040] The crushed construction materials are brought out by the rotating crushing roller 41 and moved to the position above the crushing roller 41. The powdered construction waste will hit the mask 7 upwards, and then the construction waste moves between the two crushing rollers 41. At this time, the two crushing rollers 41 can once again further refine and crush the construction waste passing between the two crushing rollers. The construction waste passing between the two crushing rollers 41 enters the diversion mechanism 5, and is screened by the diversion mechanism 5 until the push plate 46 pushes the construction waste in the guide channel 43 to be refined and crushed by the crushing roller 41, thereby realizing the simultaneous refinement and crushing of different types of construction waste. Different building materials will be crushed and mixed with each other under the rotation of the crushing roller 41, and crushing and mixing can be achieved.

[0041] Then the hydraulic telescopic cylinder 472 can be controlled to contract again to drive the push rod group 474 to move upward, and the push rod group 474 then drives the push plate 46 to move upward until the push rod group 474 drives the push and pull frame 65 to contact the L-shaped lever 63 and push the L-shaped lever 63, and repeat the above-mentioned step of moving the valve plate 61 upward to connect the feed pipe 45 with the material guide channel 43.

[0042] See also Figure 7 and Figure 8In this embodiment, the diversion mechanism 5 includes a material receiving platform 51, an extrusion bar 52, a rectangular frame 53 and an inverted V-shaped screen 54. Two material receiving platforms 51 are fixedly connected between the front and rear cavity walls of the working box 1 and are respectively located directly below the crushing rollers 41 and are symmetrically distributed on the left and right. The upper surface of the material receiving platform 51 is fixedly connected with an extrusion bar 52 that contacts the outer wall of the crushing roller 41 and has a trapezoidal vertical cross-section. The front and rear cavity walls of the working box 1 are slidably connected to the rectangular frame 53 through a reciprocating electric telescopic column 55. The front and rear opposite sides of the rectangular frame 53 are fixedly connected with an inverted V-shaped screen 54 located directly below the two crushing rollers 41 through a connecting column. The V-shaped screen 54 is slidably connected to the opposite sides of the two receiving platforms 51, and the lower end surface of the rectangular frame 53 is fixedly connected with a plurality of T-shaped rods equidistantly along the front and rear longitudinal direction, and the T-shaped rods are symmetrically arranged in two rows, and the lower end surface of the transverse section of the T-shaped rod is fixedly connected with a plurality of strip-shaped toggle pieces 8 equidistantly, and the left and right opposite sides of the rectangular frame 53 are fixedly connected with spring telescopic columns symmetrically front and back, and the ends of the front and rear adjacent spring telescopic columns are commonly fixedly connected with strip-shaped cleaning brushes 9 attached to the outer wall of the crushing roller 41, and the upper surface of the inverted V-shaped screen 54 is fixedly connected with ribs symmetrically front and back, and the vertical cross-sectional shape of the ribs matches the vertical cross-sectional shape of the inverted V-shaped screen 54.

[0043] When the construction waste is processed by the crushing roller 41 and enters the inverted V-shaped screen 54, the reciprocating electric telescopic column 55 is controlled to drive the rectangular frame 53 to move back and forth, and the rectangular frame 53 then drives the inverted V-shaped screen 54 to move synchronously through the connecting column. During the reciprocating movement of the inverted V-shaped screen 54, the screening speed of the powdered construction waste falling on its upper surface is accelerated, and the powdered construction waste that meets the required size passes through the inverted V-shaped screen 54 and falls into the working box 1, while some construction waste that is still larger in size will be intercepted by the inverted V-shaped screen 54, and then passed through the inverted V-shaped screen. Under the action of the double slope surface of 54, the construction waste rolls to the left and right sides and rolls onto the receiving platform 51. Then the surface of the rotating crushing roller 41 contacts the construction waste on the receiving platform 51 and drives the construction waste to move toward the inclined surface of the extrusion bar 52. The crushing roller 41 cooperates with the inclined surfaces of the extrusion bar 52 to further refine and crush part of the construction waste, ensuring that the construction waste can be thoroughly refined and crushed. The crushed construction waste is taken out by the crushing roller 41 from the gap between the crushing roller 41 and the extrusion bar 52, and then falls into the work box 1.

[0044] The rectangular frame 53 reciprocates back and forth, and at the same time, the strip cleaning brush 9 is driven to reciprocate on the outer wall of the crushing roller 41 through the spring telescopic column, so as to remove the fine powder attached to the outer wall of the crushing roller 41 in real time, ensuring that the crushing capacity of the crushing roller 41 is always in the best state.

[0045] The reciprocating motion of the rectangular frame 53 will also drive the T-shaped rod to move synchronously, and the T-shaped rod will then drive the strip-shaped shifting piece 8 to move, and the strip-shaped shifting piece 8 will shift the fine powder falling into the working box 1, further ensuring that the various materials in the construction waste can be further mixed.

[0046] During operation, first, the driving unit 3 is controlled to operate to drive the crushing roller 41 to rotate, and then the various materials in the construction waste that have been broken into blocks are respectively introduced into the feed pipe 45 in the cooperative integrated mechanism 4, and then the various materials in the construction materials enter the guide channel 43, and the push unit 47 is controlled to operate to move the construction waste downward. When the construction waste located at the lower part is attached to the outer wall of the crushing roller 41, the combination of the crushing roller 41 and the crushing tooth seat 44 is used to refine and crush the construction waste. During the rotation of the crushing roller 41, the crushed construction waste can also be driven to move together for mixing, and then the construction waste enters the diversion mechanism 5. The diversion mechanism 5 operates to screen the refined and crushed construction waste. The ones that meet the size pass through the diversion mechanism 5 and enter the working box 1. The ones that are still larger in size will be stopped for further refinement and crushing. The operation of the diversion mechanism 5 will also drive the strip-shaped shifting piece 8 to move back and forth, shift the powdered construction waste entering the working box 1, and further mix the various materials in the construction waste, thereby completing the coordinated regeneration processing of the micro-powder of the construction waste.
