TECHNICAL FIELD
[0001] The utility model belongs to the technical field of tunneling equipment, and particularly relates to a sewage tank for a tunneling machine and the tunneling machine. BACKGROUND
[0002] During construction, for example, when tunneling in a water-rich stratum, a tunneling machine (shield machine, TBM, etc.) is prone to produce a large amount of sewage and waste water. To avoid the impact of sewage on normal construction, a sewage diaphragm pump or submersible pump is usually arranged at the tail of the shield body, and a sewage tank is arranged on the rear supporting trailer. The sewage diaphragm pump or submersible pump pumps the sewage to the sewage tank, and the sewage is discharged outside the tunnel after being deposited in the sewage tank.
[0003] The existing sewage tank generally only has the function of storing sewage. After a period of work, the silt and slag in the sewage will deposit at the bottom of the sewage tank. After a period of work, the slag needs to be manually cleaned before the sewage tank can be used normally. For example, the patent with the authorization announcement number CN214972408U discloses a shield machine sewage treatment device (i.e., a sewage tank), which comprises a tank body, a water inlet pipe (water inlet), a drain pipe (water outlet), and a discharge port arranged on the tank body. A partition is arranged inside the tank body, which divides the cavity inside the tank body into a sedimentation chamber and a water storage chamber. The water inlet pipe and the discharge port are located on one side of the sedimentation chamber, and the water outlet pipe is located on one side of the water storage chamber. The sewage enters the sedimentation chamber from the water inlet pipe first. After the sewage in the sedimentation chamber reaches a certain amount, the "clean water" after sedimentation can enter the water storage chamber through the partition, and then be discharged from the drain pipe. The mud and slag deposited in the sedimentation chamber can be discharged from the discharge port.
[0004] However, the internal space of the tunnel is very limited. The sewage tank is generally mounted on one side of the left and right sides of the rear supporting trailer, which is very close to the tunnel wall. The operation space for manually cleaning the mud and slag in the sewage tank is very small. In addition, manual operation also has certain safety hazards. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION
[0032] In order to facilitate the discharge of the sludge deposited in the sewage tank, the basic technical concept of the utility model is to increase the deslagging device in the sewage tank, so as to send the sludge deposited in the sewage tank to the deslagging system of the heading machine, and finally send the sludge out by the deslagging system of the heading machine, and the utility model will be further described in detail in combination with the embodiments.
[0033] The specific embodiment of the sewage tank for the heading machine provided by the utility model is as follows:
[0034] As a most basic embodiment, as shown in FIG. 1, the sewage tank for the heading machine comprises a box body 7, a sedimentation cavity 2, a water storage cavity 6, a partition 5, a liquid level meter 8, a drain pump 10, a drain pipe 9, a drain port 11, a manhole 12, a first section 13, a second section 14, a swing driving device 15, a rear matching trailer 100 and a deslagging vehicle 200. Figure 1As shown, the sewage tank comprises a tank body 7, which is provided with a water inlet and a water outlet 11. The water inlet is provided with a water inlet pipe 1, and the water outlet 11 is provided with a water outlet pipe 9. A water pump 10 is arranged at the water outlet pipe 9, which can pump out the water in the tank body 7. A partition plate 5 is arranged inside the tank body 7, which divides the tank body 7 into a sedimentation cavity 2 and a water storage cavity 6. The partition plate 5 is used to prevent the sludge deposited in the sedimentation cavity 2 from entering the water storage cavity 6. The water inlet is directly communicated with the sedimentation cavity 2, and the water outlet 11 is directly communicated with the water storage cavity 6. Sewage can enter the sedimentation cavity 2 from the water inlet, and the sludge is deposited at the bottom of the sedimentation cavity 2 under the action of gravity. The "clean water" after sedimentation can enter the water storage cavity 6 through the channel between the partition plate 5 and the inner wall of the tank body 7.
[0035] The sewage tank in the embodiment is also provided with a sludge discharge device, which is used to discharge the sludge in the sedimentation cavity 2. Figure 1 and Figure 2 As shown, the sewage tank can be carried on the rear matching trailer 100 in use. The sludge discharge device has a sludge discharge channel, the two ends of which are a sludge inlet and a sludge outlet. The sludge inlet is located at the bottom of the sedimentation cavity 2, and the sludge outlet is located above the sludge discharge system of the tunneling machine in use. The sludge discharge system of the tunneling machine can be the sludge car 200 shown in the figure. Of course, the sludge discharge system can also be a belt conveyor. Since the sludge outlet is located above the sludge discharge system of the tunneling machine, the sludge in the sedimentation cavity 2 can be sent to the sludge discharge system of the tunneling machine by the sludge discharge device, and finally sent out of the hole by the sludge discharge system.
[0036] It can be analyzed that, unlike the prior art, the embodiment realizes automatic discharge of the sludge in the sedimentation cavity 2 by configuring the sludge discharge device, without manual sludge cleaning and discharging, which is convenient and efficient, and can also realize synchronous sludge discharge during tunneling.
[0037] As a preferred embodiment for convenient sludge discharge, as shown in Figure 1 and Figure 2 The sludge discharge device is a spiral sludge discharge device. The sludge discharge device comprises a shell and a spiral conveying mechanism (screw shaft and spiral blade) inside the shell. The space inside the shell constitutes a sludge discharge channel. The shell comprises a first section 13 and a second section 14, which are communicated with each other. The spiral conveying mechanism is arranged in each of the first section 13 and the second section 14. The sludge inlet is located in the first section 13, and the sludge outlet is located in the second section 14. The first section 13 penetrates the tank body 7, which is used to discharge the sludge in the sedimentation cavity 2. The second section 14 is arranged obliquely upward, which is used to convey the sludge upward to the position of the sludge discharge system (sludge car 200). The driving device (motor or hydraulic motor, not shown in the figure) of the spiral conveying mechanism can be arranged outside the tank body 7, and the two parts of the spiral conveying mechanism are respectively provided with different driving devices. For the sludge mixture, especially the spiral conveying mechanism including large sludge stones, has better sludge discharge effect.
[0038] It should be noted that in other embodiments, the slag discharge device can also use the pumping pipeline to discharge the slag, and the slag discharge pipeline (i.e. the slag discharge channel) is configured, and the slag pumping pump (such as a vacuum pump) is configured on the slag discharge management. The slag pumping pump can send the sludge in the sedimentation cavity 2 to the slag discharge system.
[0039] Based on the preferred embodiment of the spiral slag discharge device, further, as shown in Figure 1 and Figure 2 , the slag discharge port is higher than the box body 7. In this way, the water in the sedimentation cavity 2 can be completely prevented from overflowing from the slag discharge port.
[0040] In order to make the sewage tank suitable for different heights and different widths of the slag discharge system, as a preferred embodiment, the second section 14 is configured to be swingable relative to the first section 13, so that the height of the slag discharge port can be changed by adjusting the swing of the second section 14. As shown in Figure 2 , if the second section 14 is swung clockwise, the slag discharge port can be moved to a higher position. At this time, the sewage tank can be provided with a swing driving device 15 for driving the second section 14 to swing, such as a hydraulic cylinder, an electric push rod, etc. Of course, in other embodiments, the swing driving device 15 does not necessarily need to be provided on the sewage tank, but can also be provided on the rear supporting trailer 100.
[0041] As an embodiment that can make the second section 14 swing relative to the first section 13, the shell can be a flexible shell made of flexible material, which can be deformed (twisted) by itself, and the swing of the second section 14 relative to the first section 13 can be realized by the deformation of the flexible shell itself. Of course, in other embodiments, only the connection position between the second section 14 and the first section 13 can be a flexible shell, and other positions can be rigid shells. The flexible shell at the connection position can already satisfy the small swing of the second section 14.
[0042] Of course, in other embodiments, the second section 14 and the first section 13 can both be rigid shells, and if the relative swing of the second section 14 and the first section 13 is to be realized, the second section 14 can be provided with an elbow at the bottom, the elbow is inserted into the first section 13, or the first section 13 is inserted into the elbow, and a movable sealing element is arranged in the insertion gap to ensure the sealing effect.
[0043] In order to make the sludge in the sedimentation cavity 2 be discharged faster, as shown in Figure 1 , in some preferred embodiments, the part of the first section 13 located in the sedimentation cavity 2 extends to the partition plate 5, and the cross section of the part of the first section 13 located in the sedimentation cavity 2 is U-shaped, and the upward opening of the U-shaped cross section constitutes the slag inlet. In this way, the sludge deposited at various positions in the sedimentation cavity 2 can all enter the shell (slag discharge channel) directly from the slag inlet. Compared with the embodiment in which the shell is a closed circular shell and only the slag inlet is arranged at a part of the position, it is obvious that the slag discharge efficiency is higher.
[0044] In order to make the sludge in the sedimentation cavity 2 more concentratedly fall in the central position of the bottom, as shown in some preferred embodiments, the bottom wall of the box 7 is an arc-shaped structure with an upward opening. Compared with the flat structure of the bottom of the box 7, this can make the sludge more concentratedly fall in the central position of the bottom, and is more convenient for collection and discharge. Figure 2
[0045] As an embodiment with better effect of blocking sludge, as shown in some preferred embodiments, the partition plate 5 is provided with two plates, one of which is connected with the bottom wall of the box 7, and the other of which is connected with the top wall of the box 7. The two partition plates 5 are spaced apart in the arrangement direction of the sedimentation cavity 2 and the water storage cavity 6, and have overlapping parts in the projection direction perpendicular to the plate surface direction of the partition plate 5. In this way, a gap for blocking sludge is formed between the two partition plates 5, and compared with the case of providing only one partition plate 5, the effect of “filtering” sludge is better. Figure 1
[0046] Considering that in some cases, the sludge may contain sludge with strong adhesion, in some preferred embodiments, as shown in some preferred embodiments, the inside of the box 7 is also provided with a flushing device 4. The flushing device 4 has a flushing nozzle 3 for spraying flushing water to flush the inner wall of the box 7. The flushing nozzle 3 is distributed in the sedimentation cavity 2 and the water storage cavity 6. When the sludge adheres to the inner wall of the box 7 and is difficult to clean, the flushing nozzle 3 can be opened to actively flush the inner wall of the box 7 by spraying flushing water, which is convenient and efficient. Figure 1
[0047] In some embodiments, as shown in some preferred embodiments, a manhole 12 is further provided on the box 7, and a openable and closable hole door is arranged at the manhole 12. In the case of opening the hole door, the worker can enter the inside of the box 7 to carry out maintenance and cleaning work (not necessary to open). Figure 1
[0048] In addition, a liquid level meter 8 is further installed on the box 7, and the start and stop of the water pump 10 can be automatically controlled by the signal of the liquid level meter 8 to realize automatic drainage.
[0049] The specific embodiment of the tunneling machine in the utility model:
[0050] The tunneling machine comprises a rear matched trailer, and the rear matched trailer is loaded with the sewage tank described in the embodiment of the sewage tank for the tunneling machine, which will not be described in detail here.
[0051] Finally, it needs to be explained that the above is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments without paying creative labor, or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
