Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building waste recycling, in particular to a processing device for building waste collaborative recycled micro powder. BACKGROUND

[0002] Building waste collaborative recycled micro powder processing is a process of converting building waste into micro powder materials, which aims to convert these wastes into valuable building materials that can be applied to the fields of concrete, mortar, cement and other building fields to achieve the goal of resource utilization. This processing process not only reduces environmental pollution, but also saves raw material resources. Specifically, different types of building waste (such as waste concrete, waste bricks, waste stone, steel slag, waste glass and the like) are finely crushed into micro powder and mixed together, and the physical and chemical properties are improved under the interaction to realize the improvement of comprehensive performance. The overall processing flow usually includes crushing, crushing, mixing, drying and the like, and crushing and mixing are key links.

[0003] The existing crushing and mixing process usually adopts a mode of multi-stage crushing in sequence and finally mixing. Since the physical properties, composition and processing requirements of different materials in the building waste are different, for example, the common characteristics of waste concrete, waste bricks and waste stone are high hardness and strong wear resistance; steel slag has high density and hardness; waste glass has high brittleness and low hardness; and the current fine crushing processing usually needs to be repeated for multiple fine crushing steps according to different materials, and additional conveying auxiliary equipment is needed for transfer between different materials, which prolongs the processing cycle and increases the loss of materials during the transfer process.

[0004] In addition, since crushing and mixing are two independent steps, after crushing is completed, the micro powder of different materials needs to be sent into the mixing equipment for overall mixing. When a large amount of materials is processed, a long time is needed for mixing, and the mixing is not thorough, which affects the quality and uniformity of the final recycled micro powder. SUMMARY

[0005] The application provides a processing device for building waste collaborative recycled micro powder, which solves the technical problem that the existing crushing and mixing process usually adopts a mode of multi-stage crushing in sequence and finally mixing. Since the physical properties, composition and processing requirements of different materials in the building waste are quite different, different materials need to be crushed separately, and the crushing process needs to be repeated multiple times.

[0036] Please refer to Figure 3 and Figure 4The pushing unit 47 comprises a supporting plate 471 fixedly connected to the upper end face of the working box 1, a hydraulic telescopic cylinder 472 arranged on one side close to the middle of the working box 1, a strip-shaped mounting plate 473 fixedly connected to the end of the hydraulic telescopic cylinder 472, a plurality of top rod groups 474 corresponding to the pushing plates 46 fixedly connected to one side close to the guide cylinder 42 of the strip-shaped mounting plate 473, and the lower end of each top rod group 474 is fixedly connected to the upper side of the pushing plate 46 corresponding thereto.

[0037] Please refer to Figure 4 、 Figure 5 and Figure 6 The top rod groups 474 and the material conveying pipe 45 are jointly provided with a material control unit 6, the material control unit 6 comprises a valve plate 61 slidingly penetrating and connected to the right wall plate of the material conveying pipe 45 and an arc-shaped elastic sheet 62 fixedly connected to the left cavity wall of the material conveying pipe 45 and located below the valve plate 61, an L-shaped pushing rod 63 is fixedly connected to the right side of the valve plate 61, a limiting spring 64 is jointly fixedly connected between the L-shaped pushing rod 63 and the material conveying pipe 45, and a pushing and pushing frame 65 is fixedly connected to the upper part of the top rod groups 474 and cooperates with the L-shaped pushing rod 63.

[0038] Firstly, the driving motor 31 is controlled to drive the rotation of the shaft 2 connected thereto, the shaft 2 drives the rotation of the gear ring 32, the gear ring 32 drives the rotation of the other shaft 2 through the other gear ring 32, and the two shafts 2 drive the rotation of the crushing rollers 41 respectively, the rotating directions of the two crushing rollers 41 are opposite, at this time, the hydraulic telescopic cylinder 472 is controlled to shrink to the shortest state, the hydraulic telescopic cylinder 472 drives the top rod groups 474 to move obliquely upwards to the highest position, the top rod groups 474 then drive the pushing and pushing frame 65 to abut against the L-shaped pushing rod 63 and drive the L-shaped pushing rod 63 to move upwards, the L-shaped pushing rod 63 then drives the valve plate 61 to move upwards, and the material conveying pipe 45 is in a communication state with the guide groove 43.

[0039] The different types of construction waste broken into blocks are respectively fed into the material conveying pipe 45, and then the construction waste enters the material guide channel 43 through the material conveying pipe 45. When the construction waste in the material guide channel 43 reaches the required amount, the external feeding of the construction waste into the material conveying pipe 45 is temporarily stopped, and the construction waste in the material conveying pipe 45 continues to move downward until it is completely fed into the material guide channel 43. At this time, the material level of the construction waste in the material guide channel 43 does not exceed the connection position of the material guide channel 45 and the material conveying pipe 45. Then the hydraulic telescopic cylinder 472 is controlled to extend and push the top rod set 474 to move downward. The top rod set 474 then pushes the push plate 46 to move downward. The push plate 46 then pushes the construction waste in the material guide channel 43 to move downward. (During the initial downward movement of the top rod set 474, the push plate 65 is simultaneously moved downward. The downward movement of the push plate 65 gradually stops the pushing of the L-shaped pushing rod 63. Then the stretched limiting spring 64 is reset to contract and pull the L-shaped pushing rod 63 to gradually move downward. The L-shaped pushing rod 63 further drives the valve plate 61 to gradually insert into the material conveying pipe 45 until the lower part of the valve plate 61 touches the arc-shaped elastic sheet 62, cutting off the connection between the material conveying pipe 45 and the material guide channel 43.) The construction material at the lowermost part of the material guide channel 43 is pressed and attached to the outer wall of the rotating crushing roller 41 by the push plate 46. The crushing roller 41 drives the construction waste to move upward towards the gap between the crushing roller 41 and the crushing tooth seat 44. The construction material is finely crushed by the cooperation between the crushing roller 41 and the crushing tooth seat 44.

[0040] The crushed construction material is moved by the rotating crushing roller 41 to a position above the crushing roller 41. The construction waste in powder form will hit the cover 7 and then move between the two crushing rollers 41. At this time, the two crushing rollers 41 can again finely crush the construction waste passing between them. The construction waste passing between the two crushing rollers 41 enters the flow separation mechanism 5, which performs a screening process on it. When the push plate 46 pushes the construction waste in the material guide channel 43 to be completely crushed by the crushing roller 41, the simultaneous fine crushing of different types of construction waste is achieved. Different construction materials are also mixed with each other under the rotation of the crushing roller 41, achieving fine crushing and mixing at the same time.

[0041] Then the hydraulic telescopic cylinder 472 is controlled to contract, driving the top rod set 474 to move upward. The top rod set 474 then drives the push plate 46 to move upward until the top rod set 474 drives the push plate 65 to touch and push the L-shaped pushing rod 63, and the above-mentioned step of moving the valve plate 61 upward to connect the material conveying pipe 45 and the material guide channel 43 is repeated.

[0042] Please refer to Figure 7 and Figure 8In the embodiment, the shunting mechanism 5 includes a material receiving table 51, an extrusion strip 52, a rectangular frame 53, and an inverted V-shaped screen 54. Two material receiving tables 51 are symmetrically arranged on the front and rear walls of the working box 1 below the crushing rollers 41. The upper surface of each material receiving table 51 is fixedly connected with an extrusion strip 52 in contact with the outer wall of the crushing roller 41 and having a trapezoidal vertical cross-section. The front and rear walls of the working box 1 are both connected with a rectangular frame 53 through a reciprocating electric telescopic column 55. The opposite sides of the rectangular frame 53 are fixedly connected with an inverted V-shaped screen 54 below the two crushing rollers 41 through connecting columns. The inverted V-shaped screen 54 is slidably connected to the opposite sides of the two material receiving tables 51. The lower end surface of the rectangular frame 53 is fixedly connected with a plurality of T-shaped rods symmetrically arranged in two rows along the front and rear longitudinal direction. The lower end surface of the horizontal section of each T-shaped rod is fixedly connected with a plurality of strip-shaped actuating pieces 8. The opposite sides of the rectangular frame 53 are both fixedly connected with spring telescopic columns symmetrically arranged in front and back. The end portions of the adjacent spring telescopic columns are fixedly connected with strip-shaped material cleaning brushes 9 attached to the outer wall of the crushing roller 41. The upper surface of the inverted V-shaped screen 54 is fixedly connected with a baffle symmetrically arranged in front and back. The vertical cross-sectional shape of the baffle matches that of the inverted V-shaped screen 54.

[0043] When the construction waste is processed by the crushing rollers 41 and falls onto 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. The rectangular frame 53 then drives the inverted V-shaped screen 54 to move synchronously through the connecting columns. The inverted V-shaped screen 54 accelerates the screening speed of the powdery construction waste falling onto its upper surface during the reciprocating movement. The construction waste meeting the size requirement passes through the inverted V-shaped screen 54 and falls into the working box 1. Part of the construction waste with a larger size is intercepted by the inverted V-shaped screen 54 and then rolls to the left and right sides under the action of the double-slope surface of the inverted V-shaped screen 54 and falls onto the material receiving table 51. The surface of the rotating crushing roller 41 then contacts the construction waste on the material receiving table 51 and drives the construction waste to move towards the inclined surface of the extrusion strip 52. The inclined surface of the crushing roller 41 cooperates with that of the extrusion strip 52 to further crush part of the construction waste, ensuring that the construction waste is completely crushed. The construction waste after the second crushing is brought out from the gap between the crushing roller 41 and the extrusion strip 52 by the crushing roller 41 and then falls into the working box 1.

[0044] The rectangular frame 53 moves back and forth, and the strip-shaped material cleaning brushes 9 move back and forth on the outer wall of the crushing roller 41 through the spring telescopic columns, which can remove the micro-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 rectangular frame 53 reciprocating movement will also drive the T-shaped rod synchronous operation, the T-shaped rod in turn drive the strip-shaped actuating piece 8 movement, the strip-shaped actuating piece 8 again to the micro powder in the work box 1 is stirred, further ensure that each material in construction waste can further mix.

[0046] When working, first control the driving part 3 operation drive the crushing roller 41 rotation, then the broken into the building waste of each material is respectively into the material pipe 45 in the cooperative integrated mechanism 4, then each material in building material enters into the material guide channel 43, control the push unit 47 operation makes the building waste descend, when the building waste 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 holder 44 is used to finely crush the building waste, the building waste is also moved together for mixing during the rotation of the crushing roller 41, then the building waste enters into the shunt mechanism 5, the shunt mechanism 5 operation is screened to the finely crushed building waste, the size that meets is passed through the shunt mechanism 5 and enters into the work box 1, the size is still larger and is blocked for further finely crushing treatment, the shunt mechanism 5 operation will also drive the strip-shaped actuating piece 8 reciprocating movement, the powder-like building waste in the work box 1 is stirred, further make each material in the building waste mix, so that the micro powder cooperative regeneration processing of the building waste can be completed.
