Detailed Implementation

[0039] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Example 1

[0041] This embodiment proposes a construction waste crushing device for civil engineering projects, such as... Figure 1 As shown, the construction waste crushing device has a first chamber 1, a second chamber 2 and a third chamber 3; the top of the first chamber 1 is provided with a feeding port 4 and the bottom is provided with a right-downward inclined filter screen 5; the bottom of the first chamber 1 serves as the top of the second chamber 2, and the bottom of the second chamber 2 is provided with a left-downward inclined filter screen 6; the bottom of the second chamber 2 serves as the top of the third chamber 3.

[0042] In this embodiment, as Figure 1As shown, the left bottom of the second compartment 2 is horizontally connected to the sand storage tank 8 via the first electric door 7; the sand storage tank 8 is vertically connected to the sand sieve 9 via a control opening at its bottom; the sand sieve 9 has, from top to bottom, a horizontal filter screen 10 and a blade stirring assembly 11. The structure of the blade stirring assembly 11 is as follows... Figure 2 As shown, the blade mixing assembly 11 includes: a fixed base 11-1, a fixed rod 11-2, and mixing blades 11-3; multiple mixing blades 11-3 are horizontally fixed to the fixed rod 11-2, the fixed rod 11-2 is vertically fixed to the fixed base 11-1, and the fixed base 11-1 is fixed to the bottom of the sand and soil screener 9.

[0043] In this embodiment, as Figure 1 As shown, the bottom right side of the first compartment 1 is connected to the horizontal transfer chamber 13 via the second electric door 12.

[0044] In this embodiment, it should be noted that: the feeding port 4 is used to feed the initial construction waste; the lower right inclined filter screen 5 is used to screen the initial construction waste into: sandy waste and non-sandy waste; the lower left inclined filter screen 6 is used to screen the sandy waste into: small-particle soil waste and non-small-particle soil waste; and the horizontal filter screen 10 is used to screen the non-small-particle soil waste into: sandy waste and soil waste.

[0045] In this embodiment, it should be noted that: according to preset conditions, the opening / closing of the first electric door 7, the second electric door 12, and the controlled opening is adjusted by the controller; wherein, the preset conditions are: the weight of the remaining garbage in the first compartment 1 / second compartment 2 / controlled opening reaches a preset range.

[0046] In this embodiment, it should be noted that: the pore size of the filter mesh 5 (lower right inclined screen) is larger than that of the filter mesh 10 (horizontal screen); the pore size of the filter mesh 10 (horizontal screen) is larger than that of the filter mesh 6 (lower left inclined screen). Non-sand and soil waste generally includes reinforced concrete blocks, bricks, and plastic materials, and the volume of non-sand and soil waste is often larger than that of sand and soil waste. Sand and soil waste includes sand and soil, while the soil in construction waste includes lumpy soil and powdery soil. In summary, regarding the right-downward inclined filter 5, the left-downward inclined filter 6, and the horizontal filter 10, firstly, based on the right-downward inclined filter 5 with the largest filter hole diameter, non-sand waste such as reinforced concrete blocks, bricks, and plastic materials is retained, while sand and soil are screened out. Because the right-downward inclined filter 5 is tilted to the right, non-sand waste slides down from the first compartment 1 into the horizontal conveyor chamber 13 via the second electric gate 12, while the screened sand and soil naturally fall from the first compartment 1 into the second compartment 2. Secondly, based on the left-downward inclined filter 6 with the smallest filter hole diameter, the waste in the second compartment 2... The sand and clumps of soil are retained, while the powdery soil is sieved out. The sieved powdery soil falls naturally from the second chamber 2 into the third chamber 3. Due to the downward tilt of the left-hand filter screen 6, the sand and clumps of soil slide down from the second chamber 2 into the sand storage box 8 through the first electric door 7. The sand and clumps of soil then fall into the sand separator 9 through the controlled opening of the sand storage box 8. The sand separator 9 is pre-filled with water. Under the stirring action of the blade stirring assembly 11, the sand is retained through the horizontal filter screen 10 with the middle pore size among the three filters, and the clumps of soil fall to the bottom of the sand separator 9 after being dispersed.

[0047] In this embodiment, it should be noted that: in order to improve the filtration speed and efficiency of both the lower right inclined filter 5 and the lower left inclined filter 6, both the lower right inclined filter 5 and the lower left inclined filter 6 are configured as motor-driven vibrating filters; such as Figure 1 As shown, the first motor 24-1 is matched with the lower right inclined filter screen 5, and the second motor 24-2 is matched with the lower left inclined filter screen 6.

[0048] In this embodiment, as Figure 1 As shown, the right end of the horizontal conveying chamber 13 is based on the vertical crushing chamber 14 and connected to the left end of the conveying channel 15; the horizontal conveying chamber 13 is provided with a horizontal conveying platform 16; the vertical crushing chamber 14 is provided with a jaw crushing assembly 17.

[0049] In this embodiment, as Figure 1As shown, the conveyor channel 15 runs through the horizontal crushing chamber 18 from left to right, and the horizontal crushing chamber 18 is equipped with a pendulum crushing assembly 19; the end of the conveyor channel 15 is provided with a first discharge port 20 connected to the horizontal crushing chamber 18; the left side of the horizontal crushing chamber 18 is fixed to the right side of the vertical crushing chamber 14 based on the horizontal plate 21; the blower 22 and the rotary sorting assembly 23 are fixed to the bottom surface of the horizontal plate 21 from left to right; the bottom of the vertical crushing chamber 14 is provided with a second discharge port 25 matching the conveyor channel 15; the left side of the horizontal crushing chamber 18 is provided with a first inlet, and the right side of the horizontal crushing chamber 18 is provided with a third discharge port; the second discharge port 25 is based on the conveyor channel 15 and is connected to the first inlet, the third discharge port and the first discharge port 20 in sequence.

[0051] In this embodiment, it should be noted that: Figure 1 As shown, non-sand waste falling into the horizontal conveying chamber 13 is conveyed between the jaw crusher fixed plate 17-1 and the jaw crusher impact plate 17-2 by the conveying action of the conveying platform in the horizontal conveying chamber 13. Preferably, in order to ensure that the non-sand waste falls accurately between the jaw crusher fixed plate 17-1 and the jaw crusher impact plate 17-2, the inner wall of the vertical crushing chamber 14 above the jaw crusher crushing component 17 has a downward tightening trend. Non-sand waste, including reinforced concrete blocks, bricks and plastic materials, is transformed into small-volume non-sand waste under the continuous mutual impact of the jaw crusher fixed plate 17-1 and the jaw crusher impact plate 17-2. The small-volume non-sand waste falls into the conveying channel 15. Specifically, the third motor 24-3 drives the drive device 17-3, and the drive device 17-3 controls the start and stop of the jaw crusher impact plate 17-2 hitting the jaw crusher fixed plate 17-1 and the impact frequency.

[0052] In this embodiment, it should be noted that the small-volume non-sand waste obtained by the jaw crusher assembly 17 may include not only concrete fragments and broken bricks, but also some lightweight waste and metal wire-like components. The lightweight waste includes plastic materials, and the metal wire-like components include steel bars. Furthermore, when the small-volume non-sand waste is conveyed through the conveyor channel 15, the lightweight waste in the small-volume non-sand waste is blown out by the blower 22; and the metal wire-like components in the small-volume non-sand waste are automatically picked out by the sorting action of the rotary sorting assembly 23. Specifically, the blower 22 is driven by the fourth motor 24-4, and the rotary sorting assembly 23 is driven by the fifth motor 24-5.

[0053] In this embodiment, the structure of the rotary sorting assembly 23 is as follows: Figure 4 As shown, the rotary sorting assembly 23 includes: a rotary wheel 23-1 and sorting pins 23-2; multiple sorting pins 23-2 with hook-like structures at their ends are fixed to the outside of the rotary wheel 23-1; the rotation start / stop and rotation speed of the rotary wheel 23-1 are adjusted by a fifth motor 24-5; specifically, when the rotary wheel 23-1 rotates, the hook-like structures at the ends of the sorting pins 23-2 automatically pick out the metal wire-like parts mixed in with small-volume non-sand waste located on the conveying channel 15; correspondingly, a holding trough 26 adapted to the rotary sorting assembly 23 is provided on one side of the conveying channel 15, and the holding trough 26 is used to hold the picked-out metal wire-like parts; a baffle 2 is provided on the left side of the holding trough 26, and the baffle 2 is used to prevent lightweight waste from being accidentally blown into the holding trough 26.

[0054] In this embodiment, it should be noted that: the pendulum crushing assembly 19 is used to crush small-volume non-sand waste (excluding lightweight waste and wire-like components) into small-particle non-sand waste; the structure of the pendulum crushing assembly 19 is as follows: Figure 5 As shown, the pendulum crushing assembly 19 includes: a fixed plate 19-1, a rotating shaft 19-2, a fixed rod 19-3, and pendulums 19-4; the two fixed plates 19-1 are fixed to each other based on the rotating shaft 19-2 and the fixed rod 19-3, and multiple pendulums 19-4 are fixed to the fixed rod 19-3; the rotation start / stop and rotation speed of the rotating shaft 19-2 are adjusted by the sixth motor 24-6 to control the rotation start / stop and rotation speed of the pendulums 19-4; specifically, the rapid rotation of the pendulums 19-4 continuously strikes the small-volume non-sand waste that has completed the lightweight waste removal step and the metal wire component sorting step on the conveying channel 15 to obtain small-particle non-sand waste; the small-particle non-sand waste is output through the first discharge port 20 under the conveying action of the conveying channel 15. The small-particle non-sand waste can be remade into building bricks.
