Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and in particular to solid waste treatment equipment for construction engineering. Background Art

[0002] During the construction of the project, a large amount of solid waste will be generated, and the solid waste needs to be crushed regularly. These solid wastes mainly include bricks, gravel, slag, concrete fragments, plastic packaging bags and boxes of building materials, etc. There are many recyclable resources in the solid waste, so they need to be processed and reused. The main measures are screening and crushing. Bricks, gravel, slag and concrete blocks (hereinafter referred to as blocks) are screened with plastic packaging bags of building materials and other packaging boxes (hereinafter referred to as plastic parts). The screened blocks are crushed for secondary recycling. The screened plastic parts are packaged and transported to the processing plant for further processing. At present, the solid waste screening in construction projects basically adopts vibrating screen equipment, and the plastic parts are distinguished from the blocks by the vibration of the vibrating screen. Because plastic parts may be mixed in the wet concrete in many cases during the construction process, when the concrete solidifies, the plastic parts will solidify inside the concrete, which is simple. Simple vibration screening cannot separate plastic parts from concrete very well, and the vibration of the vibration screen will generate kinetic energy for the blocks, and blocks such as concrete blocks will jump on the vibration screen. Since the surface of the vibration screen is a flat screen structure, after the concrete blocks and other blocks vibrate and fall on the vibration screen again, the concrete blocks and other blocks hit the flat structure, and the kinetic energy of the concrete blocks and other blocks is absorbed by the screen, resulting in a smaller crushing effect of the blocks themselves. Moreover, the vibration screen moves the solid waste forward while vibrating. The concrete blocks and other blocks after vibration screening still contain a lot of broken slag or slag. If all of them are directly transported to the crushing equipment, under the condition that the capacity of the screening equipment remains unchanged, the crushing amount of large blocks such as concrete blocks will be reduced in the same time, which affects the working efficiency of the crushing equipment in terms of overall work efficiency. Based on the above reasons, the existing solid waste treatment equipment has the problems of poor screening effect, energy loss and low crushing efficiency during operation. Summary of the invention

[0063] Compared with the prior art, the present invention provides a solid waste treatment equipment for construction engineering, which has the following beneficial effects:

[0064] 1. The present invention can convey solid waste that needs to be screened through a conveying channel. During the conveying process, the screen is driven to vibrate on the top of the vibration box through a vibration mechanism to screen the lumps and plastic parts contained in the solid waste. Since the gravity of the lumps is greater than that of the plastic parts, the lumps will continue to move downward during the vibration process, while lighter impurities such as plastic parts will move upward. Through a separation component with an air blowing function, the lighter plastic parts that are bounced by vibration can be blown to the corresponding collection position, so that the lumps and plastic parts can be screened.

[0065] 2. The present invention can swing the solid waste continuously left and right during the vibration process through the swing assembly, so that it can contact and collide with the screen more fully, avoiding direct transportation to the next process after incomplete screening, thereby increasing the screening time of the solid waste and improving the screening effect.

[0066] 3. The present invention can crush the blocks screened out by the screening mechanism again through the crushing barrel, and can continuously push the blocks to the position of the crushing mechanism through the pushing mechanism, so that the crushing mechanism can effectively cut the blocks. The crushing barrel with a cutting function can perform a second cutting on the blocks that have been cut and crushed in the crushing barrel when they are discharged outward, thereby improving the crushing effect.

[0067] 4. In the present invention, the solid debris waste generated by the preliminary screening by the screening mechanism and the solid debris waste crushed by the crushing mechanism are finally transported to the crushing box, and the crushing shafts arranged in staggered meshing can be used for the final crushing treatment to improve the crushing effect.

[0068] 5. The present invention, by setting a screening mechanism, can utilize the kinetic energy generated by the vibration in the screening mechanism to the block, so that it continuously collides with the crushing components on the screen. After repeated collisions, the blocks with smaller hardness will be crushed during the screening process, so as to achieve the purpose of preliminary screening, and the slag and slag contained in the solid waste can be directly screened out and transported to the crushing box. The harder blocks are vibrated into the crushing cylinder, and are continuously pushed by the pushing mechanism to continuously contact the crushing mechanism, so as to achieve the purpose of cutting and crushing, and finally cut again by the crushing cylinder, and finally discharged into the crushing box, so that the smaller slag or slag contained in the solid waste and the harder blocks can be processed separately, so that the solid waste contained in each processing step is basically of the same size, thereby enhancing the pertinence of the crushing treatment, avoiding the phenomenon in the traditional technology that the same crushing equipment contains not only harder blocks but also slag and slag, and improving the crushing efficiency and effect.

During the transportation process, the screen 4 is driven to vibrate on the top of the vibration box 3 by the vibration mechanism to screen the lumps and plastic parts contained in the solid waste. Since the gravity of the lumps is greater than that of the plastic parts, the lumps will continuously move downward during the vibration process, while lighter impurities such as plastic parts will move upward. Through the separation component with an air blowing function, the lighter plastic parts that are vibrated and jumped up can be blown to the corresponding collection position, so that the lumps and plastic parts can be screened.

[0086] The crushing mechanism includes: a crushing barrel, which is arranged at the output end of the conveying channel, a curved pipe channel is arranged between the output end of the conveying channel and the input end of the crushing barrel through communication, and a pushing mechanism is arranged in the middle of the crushing barrel, and a circumferentially arranged crushing mechanism is arranged on the periphery of the pushing mechanism, the pushing mechanism is used to continuously push the block solid waste to the position of the crushing mechanism, and a rotating barrel with a cutting function is also rotatably sleeved on the outside of the crushing barrel, and the blocks screened out of the screening mechanism can be crushed again through the crushing barrel, and the blocks can be continuously pushed to the position of the crushing mechanism through the pushing mechanism, so that the crushing mechanism can effectively cut and process the blocks, and the blocks that have been cut and crushed in the crushing barrel can be cut twice when discharged outwards through the rotating barrel with a cutting function, thereby improving the crushing and crushing effect;

A swing gap is arranged between the two sides of the vibration box 3 and the two sides of the inner part of the box body 2, and the spring 17 is arranged in the swing gap. The two ends of the spring 17 are respectively connected to the outer wall of the vibration box 3 and the inner wall of the box body 2. Through the swing gap, it can be ensured that the vibration box 3 can generate a swing gap with the box body 2 under the action of the rotating seat 12. 12 is the swing of the center of the circle, wherein the cam assembly includes a rotating shaft and a cam mounted on the rotating shaft. In this embodiment, two cams are used and are respectively mounted on both sides of the rotating shaft.

Regarding the blowing assembly, the blowing assembly includes a blowing motor 35, a gear set and an impeller 36. The blowing motor 35 is installed at the top of the box body 2. A cover body 37 is arranged outside the impeller 36. The impeller 36 is installed at the top of the box body 2 through the cover body 37.

A large gear 38 is installed at the output end of the air-blowing motor 35, and a support seat is also installed at the top of the box body 2. A rotating shaft is rotatably connected to the support seat. A small gear 39 is installed at one end of the rotating shaft, and a large gear 38 is installed at the other end. The small gear 39 meshes with the large gear 38 on the air-blowing motor 35. A rotating shaft is also provided on the impeller 36. The rotating shaft rotates and passes through the cover body 37. Both sides of the rotating shaft are rotatably supported by the support seat. A small gear 39 is installed on the side of the rotating shaft close to the second large gear 38. The large gear 38 and the small gear 39 are meshed, and through the rotation of the air-blowing motor 35 and the acceleration transmission of the gear set, the impeller 36 rotates at a high speed inside the cover body 37, thereby forming a negative pressure and generating an air flow. An air inlet pipe 40 and an air outlet pipe 41 are provided on the cover body 37. The first air blowing nozzle 31, the second air blowing nozzle 34 and the third air blowing nozzle are all connected to the air outlet pipe 41 of the air-blowing assembly through the air pipe.

Then, the air flow is restricted by the air guide pipe 42 so that the air flow is blown upward longitudinally to achieve the purpose of blowing upward. In addition, the large conical head 44 can also puncture the particles entering the air guide pipe 42 during the vibration process to avoid clogging the air guide pipe 42. The air pipe can be appropriately selected as a hard pipe or a soft pipe according to the use requirements to ensure the operation of the screening mechanism.

[0098] In this embodiment, correspondingly, the staggered drive mechanism also includes: a lower toothed disc 60, a lower bracket 61, a lower sliding ring 62, a lower rotating wheel 63 and a lower gear 64.

[0099] Correspondingly, the transmission member used in this embodiment is: a transmission frame 66, which corresponds to the lower bracket 61 one by one, and the transmission frame 66 is connected to the bottom of the crushing drum, a first transmission wheel 67 is concentrically installed on the lower rotating wheel 63, and a second transmission wheel 68 is concentrically installed on the lower gear 64, the lower gear 64 and the second transmission wheel 68 are both transmission-connected to the transmission frame 66, the first transmission wheel 67 and the second transmission wheel 68 are transmission-connected by a transmission belt 69, and tensioning wheels 70 are provided on both sides of the transmission belt 69, and the tensioning wheel 70 is rotationally connected to the transmission frame 66.

[0100] It should also be noted that, in the present embodiment, a conveyor belt 71 is installed at the entrance of the conveying channel, and a power shaft 72 is provided on the side of the conveyor belt 71 close to the conveying channel, and the power shaft 72 is rotatably connected to the inner wall of the box body 2, wherein the power shaft 72 and the rotating shaft are both connected to the transmission assembly through a sprocket and chain structure (or a transmission wheel and a transmission belt 69 structure), and the impeller 36, the power shaft 72, the conveying shaft and the rotating shaft are driven simultaneously by the air blower motor 35.

[0101] Embodiment 2: Based on embodiment 1, embodiment 2 further includes a roller, which is arranged in the middle of the collection box 32. The interior of the roller is communicated with the interior of the collection box 32, and a roller motor 73 is installed on the outside of the roller. A roller is installed inside the roller, and an annular frame 74 is arranged on the roller. A plurality of pins 75 are installed on the annular frame 74. When solid waste such as plastic parts that can be blown enters the interior of the collection box 32, the rotation of the roller motor 73 drives the annular frame 74 to rotate, and the annular frame 74 drives the pins 75 to rotate, so that solid waste such as plastic parts can be continuously collected and inserted, thereby avoiding the accumulation of solid waste such as plastic parts, and the dust contained in the solid waste can also be separated from it. The dust falls to the bottom of the collecting box 32. An exhaust port is provided at the bottom of the collecting box 32. A filter cotton 76 is detachably provided on the exhaust port. The filter cotton 76 intercepts the dust. When the dust reaches a certain amount, the filter cotton 76 can be removed and the dust can be processed at the exhaust port. A take-in and put-out port is also provided on the outer wall of the drum. A transparent baffle door 77 is installed on the take-in and put-out port through a hinge. The transparent baffle door 77 is consistent with the curvature of the drum. A bolt pin is provided between the bottom of the transparent baffle door 77 and the drum. When the solid waste such as plastic parts inside the drum reaches a certain amount, the transparent baffle door 77 can be opened to take it out. When taking it out, the operator needs to wear protective gloves to avoid being stabbed by the pin 75.

[0102] It should be noted that the screen holes of the screen 4 and the aperture size of the discharge holes 26 after being separated by the cutting ring 25 are almost the same, that is, the particle size of the lumps entering the crushing box 6 is basically the same, and is also the particle size more suitable for crushing in the crushing box 6. The solid waste discharged by the screen 4 and the discharge holes 26 does not need to be particularly fine solid waste, as long as smaller particles can be formed so that the solid waste entering the crushing box 6 is basically granular solid waste of the same size. The screening mechanism is used to screen out granular solid waste of similar size and the solid waste with lower hardness is preliminarily crushed. The crushing mechanism is used to centrally crush the solid waste with greater hardness to obtain granular solid waste of similar size. The screening mechanism, the crushing mechanism and the crushing mechanism respectively centrally process solid waste of the same size and type, and the treatment effect is better than the mixed treatment method of the prior art.

[0103] In summary, when the solid waste treatment equipment for construction projects is used, the solid waste to be treated is first transported to the conveyor belt 71 through the belt conveyor, and the air blowing motor 35 is turned on. The air blowing motor 35 drives the power shaft 72 to rotate, so that the conveyor belt 71 works and the solid waste is continuously sent into the conveying channel. At this time, the impeller 36 rotates at a high speed under the action of the gear set, and the first blowing nozzle 31, the second blowing nozzle 34, and the third blowing nozzle all produce gas. The third blowing nozzle blows air upward on the vibrating solid waste, so that lighter solid waste such as plastic parts are blown upward. At the same time, under the blowing action of the first blowing nozzle 31, it is continuously blown toward the distribution pipe 33. The bottom of the distribution pipe 33 is provided with a slope shape to facilitate the sliding of solid waste such as plastic parts. When solid waste such as plastic parts enters the corner of the distribution pipe 33, it is blown by the blowing of the second blowing nozzle 34 to make it slide again, and finally enter the collection box 32, and is collected by the annular frame 74 and the pin 75. The dust is distributed on the surface of the annular frame 74, and the dust is shaken off to the bottom of the collection box 32. The dust and solid waste such as plastic parts can be handled regularly. At the same time, the vibration motor 14 is started, and the vibration motor 14 vibrates the screen 4, so that the block solid waste obtains kinetic energy and jumps up and down. When the air-blowing motor 35 rotates, the cam will also rotate, driving the vibration box 3 to swing back and forth, so that the block solid waste can jump on the screen 4 for a sufficient time, so that some block solid waste with smaller hardness can be broken as much as possible through the vibration of the screen 4 and the collision with the pointed head 5. When the air-blowing motor 35 rotates, its conveying roller 46 will also rotate, and the block solid waste will be subjected to kinetic energy again when it touches the rotating conveying roller 46, increasing the collision and crushing effect with the pointed head 5. In addition, through the rotation of the conveying roller 46, the lighter solid waste such as the blown plastic parts can be guided to avoid it from sticking to the top wall of the conveying channel and accumulating, and it is transported to the distribution pipe 33 in cooperation with the first blowing nozzle 31;

[0104] After the block solid waste and plastic solid waste inside the screening mechanism are screened, the plastic solid waste enters the collection box 32, and the solid waste with lower hardness or the granular debris and soil residue contained in the solid waste enters the crushing box 6 through the screen 4 and the first discharge pipe 8. The harder solid waste or large pieces of solid waste vibrate into the crushing box, and the drive motor 57 is turned on. The drive motor 57 drives the push barrel and the upper gear plate 51 and the lower gear plate 60 to rotate, and the harder solid waste is squeezed and pushed by the push barrel, so that it is continuously transported to the position of the A plate 22 and the B plate 23, and the sawtooth heads 21 on the A plate 22 and the B plate 23 with high-speed staggered action squeeze the solid waste. After cutting and crushing to a size that can enter the discharge hole 26, the cylinder 24 is driven to rotate by the rotation of the driving motor 57, and the cutting ring 25 is driven to rotate. The cutting and crushing are performed again horizontally by the cutting ring 25, which can not only prevent the solid waste from clogging the discharge hole 26, but also crush the solid waste again. After the solid waste is crushed, under the rotation of the cylinder 24, the shredded solid waste particles pass through the discharge hole 28 and the discharge port 29 on the annular bracket 27 to continuously overlap, so that they are continuously transported to the inside of the crushing box 6 through the second discharge pipe 30 for final crushing. The finally crushed solid waste is discharged through the output end of the crushing box 6 to the subsequent processing process.
