Description

Technical Field

[0002] Solid waste in environmental engineering refers to solid waste generated during production, daily life, and other activities. This waste includes industrial waste, domestic waste, construction waste, agricultural waste, and more. Industrial solid waste is a crucial research area in environmental engineering. Industrial solid waste primarily includes mining waste, smelting slag, and chemical waste. Mining waste, specifically waste rock and tailings generated during mining operations, is a massive quantity and poses a significant environmental risk, necessitating recycling and reuse.

[0003] Traditional mining waste recycling requires transporting waste rock to a designated location before crushing and processing. This process presents a significant problem: large solid waste ores are difficult to load when transporting the waste rock in bulk. Furthermore, if the waste rock is initially crushed before being transported and loaded to a designated location for further processing, it must be transported separately to the crushing unit. Furthermore, the crushing process generates significant dust, which poses a significant health risk to on-site workers. Summary of the Invention

DETAILED DESCRIPTION

[0046] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0047] The applicant argues that traditional mining waste recycling requires the waste rock to be transported to a designated location before being crushed and processed. This process presents a critical issue: large solid waste ores are difficult to load when transporting the waste rock in bulk. Furthermore, if the waste rock is initially crushed before being transported and loaded to a designated location for further processing, it must be transported separately to the crushing unit. Furthermore, the crushing process generates significant dust, posing a significant risk to on-site workers.

[0048] To this end, the applicant designed an environmental engineering solid waste crushing and recycling device, which can perform preliminary crushing of mineral waste rock through the crushing component 4, facilitating the loading operation of waste rock recovery. At the same time, by adjusting the discharge unit and coordinating with shoveling and digging, the generation of dust during the crushing process can be greatly reduced, thereby improving the overall crushing environment quality.

[0049] The environmental engineering solid waste crushing and recycling device involved in the present invention mainly includes three parts: a main body component, a shovel component 3 and a crushing component 4. Among them, the main body component includes a hollow base 1 with a predetermined containment capacity, which can perform corresponding load-bearing and containment operations and is provided with a corresponding open end; a crawler moving unit 2 connected to the base 1 and having a predetermined working size and supporting force; the shovel component 3 includes a positioning support unit placed on the working surface of the base 1, with a predetermined working size and supporting force; a shovel unit movably connected to the positioning support unit, with a predetermined working length and carrying space; the crushing component 4 includes a vibration crushing unit placed in the hollow chamber of the base 1; and an adjustable discharge unit connected to the vibration crushing unit, with a predetermined working length and elasticity. Through holes of predetermined working sizes are provided at the upper and lower ends of the working direction of the base 1, which serve as a loading port and a unloading port respectively.

[0050] The crawler moving unit 2 comprises two components: a rotating positioning post 201 and a movable track 202. The rotating positioning post 201 is rotatably connected to the working surface of the base 1 and has a predetermined working length and support force. There are multiple rotating positioning posts 201, each with a predetermined working distance between them, and they are arranged in an array, allowing for full-scale rotational adjustment. The movable track 202 wraps around the rotating positioning posts 201 and has a predetermined working length. It can be adjusted to a corresponding working position as the rotating positioning posts 201 rotate. There are multiple movable tracks 202, symmetrically distributed on the working surface of the base 1. In a further preferred embodiment, the working surface of the rotating positioning post 201 is evenly distributed with multiple friction bumps to increase the natural friction between the rotating positioning post 201 and the movable track 202. During later operation, the rotation of the rotating positioning posts 201 can drive the movable track 202 to rotate accordingly, thereby achieving forward and backward movement adjustment of the base 1 and the entire device. The specific operating principle of the crawler moving unit 2 can refer to the crawler vehicle structure in the prior art.

[0051] The positioning support unit comprises four components: a positioning plate 301, a support column 302, a limiting rod 303, and a push cylinder 305. The positioning plate 301 is placed on the working surface of the base 1 and has a predetermined working length and supporting force, enabling corresponding positioning and connection operations. Multiple positioning plates 301 are provided with a predetermined working distance between them. The support columns 302 are rotatably connected to the positioning plate 301 and have a predetermined working length and supporting force. Multiple supporting columns are provided, enabling rotational adjustment within a predetermined range. The limiting rod 303 is rotatably connected to the positioning plate 301 at one end and to the support column 302 at the other end via a connecting plate 304. It has a predetermined working length and is provided in multiple positions, allowing adjustment of the working angle accordingly with the rotation of the support column 302. The push cylinder 305 is rotatably connected to the positioning plate 301 at one end and to the support column 302 at the other end via a connecting plate 306. It has a predetermined working length and is provided in multiple positions, enabling telescopic adjustment within a predetermined range. During later operations, the operating angle of the support column 302 can be adjusted by extending and retracting the push cylinder 305. When the push cylinder 305 is extended, the support column 302 is lifted upward in the operating direction due to the restraint of the limit rod 303. When the push cylinder 305 is retracted, the support column 302 is pulled downward in the operating direction, and the limit rod 303 simultaneously adjusts the operating angle accordingly.

[0052] The shovel unit comprises three components: a maneuvering column 307, a pulling cylinder 308, and a bucket 310. One end of the maneuvering column 307 is rotatably connected to the connecting plate 306. It has a predetermined working length and support, and there are multiple of them, allowing for rotational adjustment within a predetermined range. One end of the pulling cylinder 308 is rotatably connected to the connecting plate 304, and the other end is rotatably connected to the adjusting column via a linkage frame 309. It has a predetermined working length and multiple of them, allowing for telescopic adjustment within a predetermined range. The bucket 310 is rotatably connected to the linkage frame 309 and communicates with the maneuvering column 307. It has a predetermined working size and load capacity, and can be adjusted to a corresponding working angle in response to the rotation of the linkage frame 309. Later in the operation, the autonomous rotation of the maneuvering column 307 can drive the pulling cylinder 308, linkage frame 309, and bucket 310 to adjust their working positions, thereby raising and lowering the bucket 310. The bucket 310 is then pulled to adjust the corresponding working angle by adjusting the extension and retraction of the pulling cylinder 308. The adjustment column 307 is connected to the connecting plate 306 via a rotating bearing, and a predetermined damping value is set between the adjustment column 307 and the connecting plate 306.

[0053] The vibration crushing unit includes four components: a crushing chamber 401, a back plate 402, a vibration crushing plate 403, and a drive motor 405. The crushing chamber 401 is placed in the hollow chamber of the base 1, is hollow and open at both ends, has a predetermined bearing space, and can perform corresponding bearing and positioning operations. The back plate 402 is connected to the inner wall of the hollow chamber of the crushing chamber 401, has a predetermined working length and supporting force, and has crushing grooves evenly distributed on the surface. The vibration crushing plate 403 is connected to the crushing chamber 401 through a vibration rotating column 404, and extends into the hollow chamber of the crushing chamber 401, leaving a predetermined working distance between it and the back plate 402, and has crushing bumps evenly distributed on the surface. The drive motor 405 is connected to the vibration rotating column 404 through a vibration track 406, is placed in the hollow chamber of the base 1, and can perform a predetermined driving force. During the later operation, the rotation of the drive motor 405 and the vibrating crawler 406 causes the vibrating rotating column 404 to vibrate, thereby causing the vibrating rotating column 404 to drive the vibrating crushing plate 403 to perform corresponding vibration adjustment as a whole, thereby vibrating and crushing the waste rock in the crushing chamber 401. The vibrating crushing unit in this application can refer to the operating process of the jaw crusher in the prior art, which is prior art and will not be described in detail in this application.

[0054] The adjustable discharge unit comprises three components: a discharge frame 5, a discharge adjustment cylinder 6, and a bottom frame 7. The discharge frame 5 is positioned below and connected to the crushing chamber 401 in its operating direction. It has predetermined operating dimensions and is equipped with corresponding through-holes for positioning and connection. One end of the discharge adjustment cylinder 6 is connected to the discharge frame 5. It has predetermined operating dimensions, can be adjusted telescopically within a predetermined range, and can be extended to a predetermined operating position outside the base 1. The bottom frame 7 is connected to the other end of the discharge adjustment cylinder 6. It has predetermined operating dimensions and is equipped with corresponding through-holes for adjusting the operating position in accordance with the telescopic adjustment of the discharge adjustment cylinder 6. The discharge frame 5 and bottom frame 7 are connected via an organ pipe 8. In a further preferred embodiment, the crushing chamber 401 is open at both ends, allowing loading through the top end and discharging through the bottom end during operation. The discharge frame 5 is connected to the open portion at the lower end of the crushing chamber 401, and can receive the crushed waste rock flowing out of the crushing chamber 401 and guide the crushed waste rock to complete the final discharge processing. When the discharge regulating cylinder 6 is extended, it drives the bottom frame 7 to move away from the discharge frame 5, so that the organ pipe 8 is stretched, thereby forming a corresponding closed discharge channel, effectively avoiding the generation of dust during the discharge process. When the discharge regulating cylinder 6 is retracted, it drives the bottom frame 7 to move toward the discharge frame 5, so that the organ pipe 8 is retracted, thereby completely exposing the crushed waste rock material, and subsequent waste rock crushing processing operations can be carried out. In order to avoid the generation of secondary dust during the exposure of the waste rock material after the crusher, the speed of the discharge regulating cylinder 6 is relatively slow when performing the retraction operation.

[0055] The inner wall surface of the discharge frame 5 in the working direction is provided with a laser radar, which can perform corresponding dust concentration detection.

[0056] A recycling method for an environmental engineering solid waste crushing and recycling device comprises the following steps:

[0057] First, the crawler moving unit 2 is driven to move toward the solid waste pile to be recycled, driving the shovel assembly as a whole to move toward the solid waste pile, and stops moving when it reaches the predetermined working position;

[0058] Next, the shovel unit is started to shovel the solid waste. By adjusting the working angle of the positioning support unit, the shovel unit as a whole is moved to the corresponding working position and angle. The material shoveled by the shovel assembly is loaded and unloaded into the vibration crushing unit, and the material is crushed by the vibration crushing unit.

[0059] Then, while the vibration crushing unit starts to perform the corresponding crushing operation, the discharging unit is adjusted to extend until the discharging unit is in contact with the ground, so that the solid waste crushed by the vibration crushing unit can be discharged with the assistance of the discharging unit;

[0060] The laser radar installed in the discharging unit is started synchronously when the discharging unit is extending to detect the dust concentration at the feeding port of the discharging unit;

[0061] When the laser radar detects that the dust concentration at the feed port of the adjusting discharging unit is lower than a predetermined value, the adjusting discharging unit is retracted to complete the corresponding unloading operation.

[0062] Finally, the above steps are repeated cyclically until all the solid waste piles to be crushed are crushed.

[0063] The laser radar set in this step includes a laser transmitter and a photosensitive receiver. When used for dust concentration detection, the laser radar must first be aimed at the target area. By emitting lasers and receiving reflected signals, the dust concentration in the air is determined based on the changes in the signals. The specific analysis steps are as follows:

[0064] When the discharging unit is adjusted to the initial state, that is, when the discharging unit is adjusted to the contracted state, the transmitter emits laser light, the receiver receives the emitted laser light, and the optical capturer captures and records the corresponding emission point. With receiving point The spatial coordinates of the two coordinate points are marked as the feature sample distance , the specific calculation formula is as follows:

[0065] ;

[0066] When the discharging unit is adjusted to start the stretching operation, the transmitter is continuously in the laser radiating state, and the optical capturer captures and locates the scattering points of the laser emitted by the transmitter at a frequency of 40 frames per second, and continuously records the spatial coordinates of the captured scattering points to generate a scattering point set. , where N represents the total number of captured scattering points, Represents the spatial location of the i-th scattering point in the set;

[0067] The coordinates of all scattering points in the scattering point set S are aligned with the emission point The coordinates of the two coordinates are calculated in turn to calculate the spatial distance and generate the scattering distance set , the specific calculation formula is as follows:

[0068]

[0069]

[0070]

[0071]

[0072]

[0073]

[0074] Where n represents the total number of scattering distances of captured scattering points, Represents the value of the scattering distance of the i-th captured scattering point in the set;

[0075] The feature sample distance The total number of arrays is the same as the total number of captured scattering points, and the array sample set Z is obtained. The array sample set Z is compared with the scattering distance set R for similarity to obtain the similarity value d(Z, R). The calculation formula is as follows:

[0076]

[0077] Where n represents the total number of scattering distances of captured scattering points, and The values ​​are the same, Represents the i-th scattering distance value in the scattering distance set R;

[0078] The dust concentration is determined by the similarity value d(Z, R). A smaller value of the similarity value d(Z, R) indicates a lower dust concentration, while a smaller value indicates a higher dust concentration. When the similarity value d(Z, R) is below 0.3, the discharge regulating cylinder 6 is activated to retract, causing the organ pipe 8 to retract, thereby completely exposing the crushed waste rock material for subsequent waste rock crushing operations.

[0079] In a further preferred embodiment, when the crushing assembly is activated, the bucket 310 can adjust its operating angle to cover the loading port of the base 1, thereby preventing dust from spreading from the loading port during the crushing process. As the discharge lift adjustment cylinder 6 retracts, the bucket 310 moves away from the loading port to proceed with the subsequent shoveling operation. A wireless signal receiver and transmitter are provided between the shovel assembly 3 and the crushing assembly 4 to receive and transmit corresponding wireless signals. This is prior art and will not be described in detail in this application.

[0080] Each component in this application can be driven by a corresponding external motor. This is existing technology and will not be described in detail in this application.

[0081] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
