Description

Technical Field

[0002] During shield construction, timely and effective transportation of the debris cut by the shield machine is an important guarantee for ensuring the normal excavation of the shield machine. If the debris cannot be discharged smoothly, it will accumulate in front of the shield machine, increasing the excavation resistance of the shield machine, affecting the construction progress, and may even cause engineering accidents such as ground subsidence.

[0003] At present, the transportation and conveying of the slag from shield construction is generally carried out by spiral conveying, and then belt conveying is used for transportation and discharge. However, in the existing technology, in the process of transporting and discharging the slag, large and small particles of slag are generally not separated and mixed for transportation. However, the weight, fluidity, friction between particles and other parameters of large and small particles of slag are different.

After the slag inside the detection chamber is humidified, it is mixed by the rotation of the detection blade and the mixing blade and then discharged by the spiral conveying of the conveying blade 2, thereby realizing the mixing and humidity detection of the small particles of slag after sorting, and performing humidity control on the slag particles with low water content, so that the composition of the slag particles finally entering the transfer and transportation is more uniform, the overall fluidity is better, and they can be better distributed on the belt of the conveying device, reducing the vibration impact during the transportation process, helping to improve the transportation efficiency and reduce the local wear of the transmission mechanism. At the same time, it can avoid dust during the transportation process, effectively improving the efficiency and safety of slag transportation. BRIEF DESCRIPTION OF THE DRAWINGS

The interior of the water tank 203 is provided with a pressure pump to provide a stable pressure inside the water tank 203. When the connecting hole 212 is connected to the water outlet hole 219, the water flow can be pumped out from the water outlet hole 219 by the pressure inside the water tank 203. The interior of the transfer box 200 is rotatably connected with a transmission pipe 205. The portion of the transmission pipe 205 extending to the outside of the transfer box 200 is transmitted to the output shaft of the motor 104 through a belt.

[0035] It should be noted that, through the design of the protrusion, the rotation of the swivel 207 can be limited to avoid excessive rotation, and through the L-shaped design of the connecting groove 215, when the swivel 207 is reset, the water flow between the transmission tube 205 and the swivel 207 can be squeezed into the interior of the connecting ring 214 through the connecting groove 215 to avoid water deposition affecting the rotation.

[0036] It should be noted that the conveying blade 210, the rotating ring 207 and the mixing blade 209 are designed and distributed in sequence from bottom to top along the vertical direction.

[0037] Furthermore, a connecting ring 217 is provided at the connection between the sleeve 206 and the rotating ring 207 , and the connecting ring 217 at the connection between the sleeve 206 and the rotating ring 207 is connected to the connecting ring 214 .

[0038] It should be noted that, through the connecting ring 217 at the connection between the sleeve 206 and the rotating ring 207, when the sleeve 206 and the rotating ring 207 rotate relative to each other, the connecting ring 217 can maintain communication with the connecting ring 214 through the annular design.

[0039] Reference Figure 1-10 The sorting mechanism includes a rotating cylinder 300 rotatably arranged on the inner side of the conveying pipe 101, a cutter head 301 is movably sleeved on the inner side of the rotating cylinder 300, a spring 2 303 is arranged between the cutter head 301 and the rotating cylinder 300, a cutter group 302 is arranged at the end of the cutter head 301 away from the rotating cylinder 300, a filter screen 304 is arranged on the side wall of the conveying pipe 101, a discharge trough 305 is also provided on the side wall of the conveying pipe 101, a transmission assembly is arranged between the rotating cylinder 300 and the rotating shaft 102, a channel 202 is opened inside the transfer box 200, and a filter plate 211 is also arranged inside the transfer box 200.

[0040] Reference Fig.10 The transmission assembly includes a driving gear 107 arranged on the outer wall of the rotating shaft 102, a gear ring 306 is opened on the inner side of the rotating cylinder 300, and a transmission gear 307 meshing with the gear ring 306 and the driving gear 107 is arranged at the end of the rotating cylinder 300.

[0041] It should be noted that the knife set 302 is provided with saw teeth, and the knife set 302 is designed to be arc-shaped as a whole, and there are multiple sets of knife sets 302 distributed in a ring shape along the axis of the rotating shaft 102.

[0042] Furthermore, the filter plate 211 is designed to be inclined, and the mesh gap size of the filter plate 211 and the filter screen 304 is the same.

[0043] It should be noted that the highest point of the conveying blade 103 matches the designed position of the discharge trough 305, so that the conveyed material of the conveying blade 103 can be discharged from the discharge trough 305. The position of the cutter head 301 also matches the position of the discharge trough 305. The cutter head 301 can block the discharge trough 305, reduce the gap of the discharge trough 305, and prevent large particles from being discharged directly through the discharge trough 305.

[0044] The working process of the slag safety transfer device used in shield construction is as follows:

[0045] The motor 104 is started, and the slag generated during the shield construction can be lifted and transported toward the rotating drum 300 in the form of a spiral conveyor through the rotation of the rotating shaft 102 and the conveying blade 103. When the slag material is transported to the area where the filter screen 304 is located, the slag material with smaller particles can be directly discharged from the filter screen 304 and fall onto the surface of the filter plate 211, and further enter the interior of the detection chamber 204 through the filter plate 211, while the slag material with larger particles is continuously lifted and transported to the corresponding area of ​​the discharge trough 305. Since the rotating drum 300 blocks a part of the discharge trough 305, the materials that meet the discharge conditions can pass through the discharge trough 305 and the cutter head 303. 01 directly falls into the gap between the filter plate 211 for filtration, small particles enter the detection chamber 204, larger particles follow the surface of the filter plate 211 into the channel 2 202, and large particles cannot be discharged through the gap between the discharge trough 305 and the cutter head 301. With the continuous conveying of the conveying blade 103, the increase of materials continues to push the slag materials upward and press against the cutter head 301, and the spring 2 303 is compressed. At the same time, under the rotation effect of the shaft 102, the driving gear 107 can drive the gear ring 306 to decelerate through the transmission gear 307, so as to realize the differential rotation of the rotating cylinder 300 and the rotating shaft 102, and the rotating cylinder 300 and the rotating shaft 102 are rotated. 00 further drives the cutter head 301 to rotate at a differential speed. The differential rotation can prevent the material inside the conveying pipe 101 from rotating synchronously with the cutter head 301, the rotating shaft 102 and the conveying blade 103. Therefore, the cutter head 301 can use the cutter group 302 to grind and crush the large-particle slag material on the top at a low speed through differential rotation. The crushed slag can fall into the surface of the filter plate 211 through the gap between the discharge trough 305 and the cutter head 301 for filtration and sorting. Large-particle slag materials such as pebbles and stones are difficult to be discharged through grinding and crushing. As the conveying blade 103 continues to transport the material, the cutter head 301 can be continuously pushed by the large-particle material to carry out The compression of the second dynamic spring 303 not only increases the relative force between the knife group 302 and the slag, and improves the grinding and crushing effect, but also increases the gap between the discharge chute 305 and the cutter head 301. When the large particles of material are not crushed and refined until the gap between the discharge chute 305 and the cutter head 301 is expanded to allow the large particles of material to be discharged, at this time, under the rotation of the knife group 302, the arc design of the knife group 302 can push the large particles of material in the direction away from the rotating shaft 102, so that it is discharged through the gap between the discharge chute 305 and the cutter head 301, and the large particles of slag material enter the interior of the channel 2 202 through the sorting of the filter plate 211.

[0046] After the small particles of slag material enter the detection chamber 204, the transmission tube 205 rotates under the transmission action of the motor 104, driving the conveying blade 210 and the sleeve 206 to rotate. When the sleeve 206 rotates, it can drive the rotating ring 207, the detection blade 208 and the mixing blade 209 to rotate synchronously, and fully mix the slag material in the detection chamber 204, and discharge the mixed slag material into the channel 1 201 through the conveying blade 210. The mixing can make the slag particles with different parameters such as particle size, hardness and humidity in the slag The materials are fully mixed to make their components more uniform, improve the overall fluidity, enhance the conveying efficiency and reduce the local wear of the conveying mechanism. In the process of mixing the slag materials by the mixing blades 209 and the detection blades 208, the mixing blades 209 can rotate and mix the slag materials entering the detection chamber 204, and the detection blades 208 can further mix and detect the preliminarily mixed materials. When the detection blades 208 rotate to mix and detect, when the overall water content of the mixed slag materials is low, the fluidity is poor, and the detection blades 208 are subjected to The resistance is greater, thereby increasing the relative rotation displacement distance of the swivel 207 and the transmission tube 205, and increasing the compression degree of the spring 1 216. When the relative rotation distance of the swivel 207 and the transmission tube 205 makes the swivel 207 rotate to break away from the blockage of the connecting groove 1 213, at this time, under the pressure of the pressure pump inside the water tank 203, the water inside the water tank 203 is pumped into the transmission tube 205 through the connecting hole 212, and further pumped into the inside of the connecting ring 214 through the connecting groove 1 213 and the connecting groove 2 215. The water flows through the connecting ring 214. The connection with the connecting ring 217 further enters the connecting pipe 218 and is discharged through the one-way valve arranged inside the water outlet 219, so as to humidify the debris inside the detection chamber 204, and further adjust the humidity through the stirring of the detection blade 208 and the mixing blade 209, and then is discharged to the channel 1 201 in a spiral conveying manner through the rotation of the conveying blade 210. Finally, the small-particle debris after the humidity adjustment is discharged through the channel 1 201 and transported by the conveyor belt 1 105, while the large-particle material is discharged through the channel 2 202 and transported by the conveyor belt 2 106.

[0047] During the process of spirally conveying the slag through the conveying pipe 101, the device performs preliminary filtration and discharge of the slag through the filter screen 304, and directly discharges the small particles of slag through the discharge trough 305, and utilizes the knife group 302 to grind and crush the large particles of slag materials through the differential rotation of the cutter head 301, thereby effectively preventing the agglomerated slag materials from mixing with the large particles of slag materials. At the same time, through the elastic design of the cutter head 301, the gap between the discharge trough 305 and the cutter head 301 is adjusted to discharge the large particles of slag materials that are difficult to crush, and the slag materials are filtered and sorted through the filter plate 211, so that the large particles and small particles of slag materials are finally conveyed through the conveyor belt 2 106 and the conveyor belt 1 105 respectively, thereby realizing automatic sorting of the slag after conveying and transferring them separately according to the particle size, reducing the damage to the conveying device and the instability of conveying caused by mixed conveying, and effectively improving the conveying efficiency and safety.

[0048] The soil particles inside the detection chamber 204 are mixed by rotating the detection blade 208 and the mixing blade 209, and the humidity of the soil particles is detected by the resistance encountered by the detection blade 208 when rotating. When the humidity is low, the relative rotation displacement distance of the rotating ring 207 and the transmission pipe 205 increases, and the water inside the water tank 203 enters the interior of the connecting pipe 218 through the transmission pipe 205, the connecting groove 1 213, the connecting groove 215, the connecting ring 214 and the connecting circle 217, and is discharged through the water outlet 219, so that the soil inside the detection chamber 204 is humidified. The detection blade 208 rotates and mixes the mixture, and then the mixture is spirally conveyed and discharged through the conveying blade 210, thereby achieving mixing and humidity detection of the small particles of slag after sorting, and humidity adjustment treatment of the slag particles with low water content, so that the composition of the slag particles that finally enter the transfer and transportation is more uniform, the overall fluidity is better, and they can be better distributed on the belt of the conveying device, reducing the impact of vibration during the transportation process, helping to improve the transportation efficiency and reduce local wear on the transmission mechanism, while avoiding dust during the transportation process, effectively improving the efficiency and safety of slag transfer and transportation.

[0049] It should be noted that the detection blade 208 is arranged at the lower part. Since the moisture of the slag will flow downward under the action of gravity, if the moisture is relatively high, the slag in the rotating mixing area of ​​the lower detection blade 208 will inevitably have a certain humidity and fluidity, which can reduce the interference of uneven moisture distribution on the detection and humidity control work, ensure the humidity control of the slag and avoid excessive humidity control.
