Description

TECHNICAL FIELD

[0002] With the development of society, the construction of urban rail transit, underground pipe gallery and river and lake management projects, geotechnical engineering operations are becoming more and more widespread, and a large amount of muck is generated in shield construction, so that the treatment of muck has become an industry problem. The muck is generally composed of sand, soil and water of different particle sizes. At present, the muck in shield construction is generally not treated, and the muck is directly transported and filled, which causes resource waste, environmental pollution and huge economic losses. The unreasonable discharge of existing slurry seriously pollutes the environment and water resources, and hides major safety hazards such as geological disasters. Strengthening the management of disposal and ensuring the effectiveness of building slurry management, exploring the ways of resource utilization, reduction and harmless in-situ treatment of advanced slurry treatment equipment, will cause pollution of the environment during transportation and disposal, and the direct disposal of recyclable materials will cause resource waste. Piling up not only wastes land resources, but also significantly reduces the internal uniformity of the pile, which may cause soil landslides and other hazards under rainfall conditions.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] In the separation and treatment of the muck generated in the shield construction, the muck separation process mainly consists of a feeding system, a stone washing system, a screening system, a sand washing and fine sand recovery system, a filter pressing treatment system, a spraying system, etc. The feeding system can be fed by a loader or a hook machine, or a robot can be preset to feed, effectively reducing the labor intensity of manual work. The stone washing system adopts a drum-type stone washer, which is continuously rotated and stirred, and water is sprayed to clean the mud adhered to the sand to a great extent, reducing the difficulty of subsequent process treatment. The screening system can be provided with 2-3 layers of vibrating screens according to the need to classify materials of different particle sizes. The sand washing and fine sand recovery system adopts two wheel-type sand washers, a high-frequency dehydration screen, a slurry pump, and a cyclone to recover fine sand of ≥74 μm or more, reducing the loss of fine sand. The filter pressing system mainly includes a thickening tank, a filter press, a slurry pump, and other equipment to press filter the mud of <74 μm into a mud cake, which can be used to make bricks, and the clean water pressed out forms a cycle with the spraying system. The spraying system mainly consists of a water pump and a pipeline to clean the mud on the muck.

[0022] The shield slag treatment process can dispose 150-200 cubic meters / hour of shield slag, specifically, the hole slag is lifted into the drum stone washing machine through the buffer bin and the large-inclination-angle belt, and is washed and screened to remove mud, and <5mm is washed and screened in the sand washing and fine sand recycling integrated machine, the cyclone and the vibrating screen, and then is put into the stockpile, and >5mm is screened in the screening machine to obtain three kinds of materials of 5-10mm, 10-26mm and >26mm, and 0-5mm is put into the sand washing and fine sand recycling machine through the slurry pump and then is put into the stockpile, and the overflow slurry of the cyclone is concentrated and flocculated and then is put into the filter press to be compacted into a mud cake; the overflow clear water is recycled into the stone washing machine to clean the materials, and the whole system is recycled without external discharge, and the filter pressing treatment system is the most important for the shield slag treatment and recycling, in order to avoid resource waste, specifically: As Figures 1 to 9 shown, the shield slag separation treatment system comprises a machine body assembly 1, the machine body assembly 1 comprises a machine frame 101, a plurality of filter pressing assemblies 2 are arranged in the machine frame 101, a supporting frame 110 is arranged above the machine frame 101, and a cleaning assembly 3 is arranged at an end of the supporting frame 110 away from the machine frame 101.

[0023] As Figure 5 shown, the filter pressing assembly 2 comprises a filter pressing frame 201, a filter pressing plate 202 is arranged in the filter pressing frame 201, guide plates 205 are arranged at both sides of the filter pressing frame 201, an inlet 203 is arranged at the surface center position of the filter pressing plate 202, and liquid outlets 204 are formed at the surface four corners of the filter pressing frame 201 and the filter pressing plate 202.

[0024] As Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, a main hydraulic cylinder 105 is arranged at one end of the machine frame 101, a pressing plate 106 is arranged at one end of the output shaft of the main hydraulic cylinder 105, a thrust plate 107 is arranged at an end of the machine frame 101 away from the pressing plate 106, an inlet pipe 108 is arranged at the surface center position of the thrust plate 107, liquid discharge pipes 109 are arranged at the surface four corners of the thrust plate 107, a collecting table 102 is arranged at the bottom end of the machine frame 101, a guide rail 103 is arranged at one side of the machine frame 101, a pull plate trolley 104 is assembled on the guide rail 103, and the pull plate trolley 104 is used for moving the guide plates 205.

[0025] The solid particles and water in the slurry are separated by a filter press, specifically, first, the pressing plate 106 is pressed by controlling the main hydraulic cylinder 105, then the material to be separated is transported into the filter press assembly 2 through the feed pipe 108 on the thrust plate 107 by the feed pump, in the process of feeding, the solid particles in the material will stay on the surface of the filter cloth, and the liquid will enter the filter chamber through the filter cloth, then the main hydraulic cylinder 105 pushes the pressing plate 106 to exert pressure on the filter frame 201 on the filter press assembly 2, under the action of the pressure, the solid particles in the liquid are intercepted by the filter cloth, realizing solid-liquid separation, the liquid passes through the liquid outlet 204 and finally collects on the liquid discharge pipe 109 on the thrust plate 107, when the filtration is completed, the pressing plate 106 stops exerting pressure on the filter frame 201 by controlling the main hydraulic cylinder 105, then the material is unloaded, the guide plate 205 is pulled by the pull plate trolley 104, thereby driving the filter frame 201 and the filter plate 202 to move together, and then the filter cake is dropped.

[0026] When the plate-and-frame filter press is in use, the filtration of the filter cloth on the filter plate 202 cannot be monitored in real time; during the feeding process, the blockage of the filter plate 202 can cause the filtration channel to narrow, making it difficult for the water in the sludge to pass through the filter cloth and the filter plate 202, thereby causing the filtration efficiency to decrease and affecting the filtration effect; after the filtration, part of the filter cake adheres to the surface of the filter cloth, which usually needs to be cleaned manually, and the efficiency is low.

[0027] To solve the above problems, the device further comprises: As Figures 8 to 9 shown, the cleaning assembly 3 comprises a mounting frame 301, the mounting frame 301 is arranged above the rack 101, the inside of the mounting frame 301 is provided with a spraying pipe 302, a plurality of liquid outlets 303 are arranged below the spraying pipe 302, a spray branch pipe 304 is arranged at the end of the liquid outlet 303 away from the spraying pipe 302, a guide frame 305 is arranged on the spray branch pipe 304, a flow guide plate 306 is arranged on one side of the guide frame 305, a flushing pipe 307 is arranged at both ends of the spraying pipe 302, a control valve is assembled on the flushing pipe 307, a liquid conveying hose 308 is arranged on one side of the spraying pipe 302, and a liquid storage tank 309 is arranged at the end of the liquid conveying hose 308 away from the spraying pipe 302.

[0028] The upper portion of the mounting frame 301 is provided with a moving track 313, which is fixedly connected to the support frame 110 near one end of the mounting frame 301. The moving track 313 is provided with a ball screw 312 on one side. The surface of the ball screw 312 is provided with a sliding frame 311. One end of the moving track 313 is provided with a driving motor 314. The output shaft of the driving motor 314 is connected to the ball screw 312. There are two ball screws 312, which are respectively located at both ends of the sliding frame 311. The surface of the sliding frame 311 is provided with a fixing groove matched with the liquid storage tank 309. The two ends of the mounting frame 301 are provided with hydraulic rods 310. One end of the hydraulic rod 310 away from the mounting frame 301 is fixedly connected to the sliding frame 311.

[0029] The inside of the guide plate 205 is provided with a pressure sensor, which is arranged at one end of the guide plate 205 close to the rack 101. The pressure sensor is used to detect whether the amount of sludge adhered to each filter pressing assembly 2 is full when feeding. If the detection value of the pressure sensor on a certain filter pressing assembly 2 is too low, it indicates that the filter pressing assembly 2 is blocked. At this time, high-pressure water flow is introduced into the liquid discharge pipe 109 on the thrust plate 107 through the pipeline. The liquid enters the inside of the filter pressing plate 202 through the liquid outlet 204 on the filter pressing plate 202, so as to realize the purpose of washing the surface of the filter cloth on the filter pressing plate 202, thereby improving the blockage at this position and ensuring the normal operation of the filter pressing work.

[0030] It is worth noting that the pipeline is connected with the liquid discharge pipe 109. The pipeline is composed of a plurality of connecting pipes (not shown in the figure). The pipeline can not only discharge the liquid in the liquid discharge pipe 109, but also can introduce high-pressure water flow into the liquid discharge pipe 109 for washing.

[0031] And due to the filter cake adhering to the surface of the filter cloth after pressure filtration, if not cleaned in time, it will affect the filtration efficiency in the subsequent feeding process. The blockage of the filter plate 202 will cause the filtration channel to narrow. In order to facilitate cleaning, the detection value of the pressure sensor is used to determine which filter assembly 2 has more adhered filter cake. In the first stage, when the detection value of the pressure sensor exceeds the preset value, the driving motor 314 drives the ball screw 312 to rotate, thereby causing the sliding frame 311 to move along the moving track 313, so that the sliding frame 311 moves to that position as a whole. Then the hydraulic rod 310 is controlled to extend, and the hydraulic rod 310 drives the mounting bracket 301 and the spray pipe 302 to move towards the collection table 102, so that the liquid outlet 204 on the filter plate 202 corresponds to the liquid outlet 204 on the filter plate 202. The positioning of the spray pipe 302 is realized, and then the driving motor 314 drives the ball screw 312 to rotate, thereby causing the sliding frame 311 to move along the moving track 313 towards the filter plate 202. At this time, the liquid outlet 204 on the spray pipe 302 enters the liquid outlet 204 on the filter plate 202, and the flow guide plate 306 is inserted into the filter cake on the filter plate 202. Then the liquid in the spray pipe 302 passes through the liquid outlet pipe 303 and is sprayed from the spray branch pipe 304, and the liquid sprayed from the spray branch pipe 304 enters the interior of the filter cake along the guide frame 305 and the flow guide plate 306. Thus, the spray liquid directly enters the gap between the filter cake and the filter cloth on the filter plate 202, thereby effectively reducing the adhesion between the filter cake and the filter cloth on the filter plate 202, and under the action of the gravity of the filter cake itself, the filter cake falls downward as a whole, achieving the purpose of separating the filter cake from the filter cloth. It can reduce the blockage of the filter cake on the filter cloth and prolong the service life of the filter cloth.

[0032] Then after cleaning, the driving motor 314 drives the ball screw 312 to rotate, thereby causing the sliding frame 311 to move along the moving track 313 away from the filter plate 202. At this time, the liquid outlet 204 on the spray pipe 302 moves away from the liquid outlet 204 on the filter plate 202. Then the hydraulic rod 310 is controlled to retract, and the hydraulic rod 310 drives the mounting bracket 301 and the spray pipe 302 to move away from the collection table 102, thereby restoring to the initial height.

[0033] It is worth noting that the purpose of the device is to realize the reduction of shield sludge and mud transportation, environmental protection treatment and full resource utilization. At this time, the spraying method will not have too much impact on it, that is, the spraying amount of the spraying method will cause the change of the water content of the filter cake. The influence of this change on the final reduction of sludge transportation can be ignored.

[0034] In the above process, since the cleaning difficulty of the mud cake is related to the dryness of the mud cake, if the mud cake is too dry, it will be bonded to the surface of the filter cloth on the filter plate 202, and it is difficult to clean, so a pressure sensor is arranged in the inner part of the guide plate 306, and when the guide plate 306 is inserted into the mud cake, the resistance is detected, if the detection value of the pressure sensor on the guide plate 306 is in the standard range, it indicates that the hardness of the mud cake is appropriate, at this time, the first stage cleaning method is used to clean it.

[0035] It is worth noting that at this time, if the hardness of the mud cake on the same filter plate 202 is different, the spraying amount of the spraying branch pipe 304 at different positions is adjusted according to the detection value of the pressure sensor, so as to ensure that the degree of wetting of the mud cake is consistent, so that the whole mud cake falls off, at this time, the cleaning strength is best.

[0036] If the detection value of the pressure sensor on the guide plate 306 exceeds the maximum threshold of the standard range, it indicates that the hardness of the mud cake is large, and the mud cake will be bonded to the surface of the filter cloth on the filter plate 202, at this time, by opening the control valve, the liquid enters through the liquid outlet 204 on the filter plate 202 through the flushing pipe 307, at this time, the volume of the liquid in the filter plate 202 increases, so as to quickly wet the filter cloth on the filter plate 202, avoid that part of the mud cake is bonded to the surface of the filter cloth on the filter plate 202 during cleaning, affect the effect of the whole mud cake falling off, at the same time, control the liquid in the spraying pipe 302 to pass through the liquid outlet pipe 303 and be sprayed from the spraying branch pipe 304, the liquid sprayed from the spraying branch pipe 304 directly enters the gap between the mud cake and the filter cloth on the filter plate 202 along the guide frame 305 and the guide plate 306, under the action of the water flow, the separation of the mud cake and the filter cloth is accelerated, the adhesion between the mud cake and the filter cloth on the filter plate 202 is reduced, and the whole mud cake falls down under the action of its own gravity, so as to quickly clean it.

[0037] It is worth noting that in order to facilitate the cleaning of the surfaces of the filter cloths on both sides of the filter plate 202, two groups of sliding frames 311 can be arranged on the moving track 313, and the guide frames 305 on the two groups of sliding frames 311 are symmetrically arranged, for cleaning the surfaces of the filter cloths on both sides of the filter plate 202 respectively (only one group of sliding frames 311 is shown in the drawings), in addition, the above operation is cooperated with the spraying branch pipe 304 and the flushing pipe 307, which can not only clean the mud cake with large hardness, but also clean the filter cloth on the filter plate 202 after the mud cake is cleaned, and wash the small mud cake debris on the surface of the filter cloth, so as to realize the quick cleaning of the filter cloth, and the characteristic of this method is high cleaning efficiency and saving water resources.

[0038] The present application also provides a shielded sludge separation and treatment process, and the specific process steps are as follows: S1: First, the muck sludge generated by shield construction is treated and then enters the material pile, and then the overflow sludge of the cyclone is treated by concentration and flocculation and then enters the filter press; S2: Then, the filter press assembly 2 on the machine body assembly 1 is used to compact the sludge into a mud cake, that is, to separate the solid particles and water in the slurry, so as to achieve the purpose of solid-liquid separation of the muck sludge; S3: Finally, the cleaning assembly 3 is used to clean the mud cake adhered to the filter press assembly 2, so as to ensure that the filter press assembly 2 can normally perform the filtering work subsequently.
