Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and in particular to an integrated tunnel construction wastewater treatment device. Background Technology

[0002] Tunnel construction generates a significant amount of wastewater mixed with silt and sand. Direct discharge of this wastewater would harm the environment, necessitating silt and sand separation using wastewater treatment equipment to remove the large amounts of silt and sand. For relatively clean wastewater from seepage and fissures, silt and sand separation can often be discharged directly. However, if the wastewater still does not meet discharge standards after silt and sand separation, it must undergo further treatment in subsequent processes. Silt and sand separation is a crucial step in handling wastewater from tunnel construction.

[0003] In existing technologies, to treat tunnel wastewater, collection trenches or tanks are typically installed at the construction site, with filters installed at the drain outlets to separate sediment from the wastewater. However, in practice, the filters inside the collection devices are easily clogged by sediment or debris, affecting filtration efficiency. To address this issue, some construction sites install aeration devices at the filters, using intermittent aeration to backwash them. While this method alleviates clogging to some extent, residual sediment or impurities inside the collection device are still difficult to remove. When sediment or impurities accumulate significantly, it also affects the efficiency of subsequent wastewater treatment. Furthermore, space is typically limited at tunnel construction sites. Therefore, exploring a wastewater treatment device that is compact, can be deployed on-site, and ensures effective treatment is a pressing technical problem in this field. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problem that in some existing wastewater treatment equipment, the internal filter screen is easily clogged by silt or debris when filtering wastewater, and the trapped silt or impurities are inconvenient to discharge. When a large amount of silt or impurities accumulate, it affects the wastewater treatment efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated tunnel construction wastewater treatment device includes: a housing with a wastewater inlet channel at the top and a drain outlet on the side wall of the housing; an inner cavity formed on the inner wall of the housing, with an outlet perpendicular to the wastewater inlet channel, and a baffle slidably embedded in the inner cavity; a sleeve plate located on the inner wall near the drain outlet; a centrifugal ring nested in a mounting hole of the sleeve plate, with its top opening below the outlet; openings on the side wall of the centrifugal ring and multiple slots on its lower side wall; the inner wall of the mounting hole fitting against the outer surface of the centrifugal ring located within the mounting hole; a rotary drive device connected to the centrifugal ring; a conical collar located below the centrifugal ring, with an impurity discharge outlet on the housing wall between the conical collar and the centrifugal ring; and a hydraulic lifting device located below the conical collar and connected to the centrifugal ring.

[0007] A hydraulic cylinder is provided below the conical collar, and the output end of the hydraulic cylinder is connected to the centrifugal ring.

[0008] The output end of the hydraulic cylinder is connected to the movable plate, which is located below the conical collar.

[0009] A limiting groove is formed on the inner wall of the box, and the end of the movable plate is slidably embedded in the limiting groove.

[0010] A drive motor is mounted on one side surface of the moving plate, and the output end of the drive motor is connected to the mounting plate at the bottom of the centrifugal ring.

[0011] A second hydraulic cylinder is also provided, the output end of which extends laterally into the inner cavity and is connected to the stop block.

[0012] A mounting bracket is provided on the outer surface of the housing, and the second hydraulic cylinder is mounted on the mounting bracket.

[0013] A funnel block is provided on the inner wall of the box located below the inner cavity. A funnel-shaped channel is formed in the center of the funnel block, and the bottom opening of the funnel-shaped channel is located above the top opening of the centrifugal ring.

[0014] A positioning shaft is fixedly installed inside the multiple slots, and a baffle is movably sleeved on each positioning shaft.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] (1) The integrated tunnel construction wastewater treatment device of this utility model controls the closing of the wastewater interface channel outlet by driving the baffle to move inside the inner cavity. At the same time, the centrifugal ring is driven to move back and forth in the vertical direction by the hydraulic lifting device. The centrifugal ring has openings on its side wall and multiple slots on its lower side wall. The inner wall of the mounting hole is in contact with the outer surface of the centrifugal ring located in the mounting hole. When the multiple slots are located in the mounting hole, the slots are closed. At this time, the wastewater interface channel is opened to let the wastewater into the centrifugal ring. The rotation drive device is started to drive the centrifugal ring to rotate. The centrifugal force drives the wastewater through the openings on the surface of the centrifugal ring and discharges the wastewater through the drain outlet. The mud and impurities remain inside the centrifugal ring, thereby completing the separation of impurities in the wastewater and improving the treatment efficiency. At the same time, the integrated tunnel construction wastewater treatment device of this application occupies a small area and is easy to arrange at the tunnel construction site.

[0017] (2) In the integrated tunnel construction wastewater treatment device of this utility model, after the wastewater treatment is completed, the hydraulic lifting device drives the centrifugal ring to move downward. As a preferred embodiment, the lifting of the centrifugal ring can be further limited by the limiting groove, so that the groove opening is disengaged from the inside of the sleeve plate. At this time, the drive motor is started again to drive the centrifugal ring to rotate. With the help of centrifugal force, the baffle on the surface of the positioning shaft rotates, so that the mud and sand inside the centrifugal ring fall into the surface of the conical sleeve ring and slide out through the impurity discharge port. After cleaning is completed, the hydraulic lifting device works again to move the centrifugal ring on the surface of the mounting plate upward along the inside of the sleeve plate for reset. At the same time, it moves through the baffle to enter the next wastewater treatment cycle. The integrated tunnel construction wastewater treatment device of this utility model does not require manual cleaning and is also convenient for subsequent deep treatment or reuse of wastewater.

The inner wall surface of the mounting hole is in contact with the outer surface of the centrifugal ring 1064 located within the mounting hole. In this embodiment, a positioning shaft 1066 is fixedly provided inside the multiple slots 1065, such as... Figure 4 As shown, baffles 1067 are movably sleeved on the outer surface of the multiple positioning shafts 1066, and the baffles 1067 are slidably embedded inside the sleeve 107.

[0029] A conical collar 108 is provided below the centrifugal ring 1064. An impurity discharge port 103 is provided on the wall surface of the box between the conical collar 108 and the centrifugal ring 1064. The conical collar 108 has a structure that is narrow at the top and wide at the bottom. The bottom edge of the conical collar 108 abuts against the inner wall of the box 1.

[0030] The integrated tunnel construction wastewater treatment device is also equipped with a hydraulic lifting device, which is a hydraulic cylinder 106. The hydraulic cylinder 106 is located below the conical collar 108, and its output end is connected to the centrifugal ring 1064. In this embodiment, the output end of the hydraulic cylinder 106 is connected to a moving plate 1061, which is located below the conical collar 108. A limiting groove 105 is formed on the inner wall of the housing 1, and the end of the moving plate 1061 is slidably embedded in the limiting groove 105 to limit the movement path of the output end. A rotary drive device is installed on the upper surface of the moving plate 1061. The rotary drive device is a drive motor 1062, and its output end is connected to the mounting plate 1063 at the bottom of the centrifugal ring 1064. The output end of the drive motor 1062 passes through the annular hole of the conical collar 108.

[0031] In a preferred embodiment, the integrated tunnel construction wastewater treatment device is further equipped with a second hydraulic cylinder 201. The output end of the second hydraulic cylinder 201 extends laterally into the inner cavity 104 and is connected to the stop block 202. A mounting bracket 2 is provided on the outer surface of the housing 1, and the second hydraulic cylinder 201 is mounted on the mounting bracket 2. The output end of the second hydraulic cylinder 201 penetrates the side wall of the housing 1 and enters the inner cavity 104.

[0032] As a preferred embodiment, a funnel block 109 is provided on the inner wall of the box 1 located below the inner cavity 104 for collecting wastewater from the wastewater inlet channel 101.

[0033] The working process of the integrated tunnel construction wastewater treatment device described in this embodiment is as follows: During use, wastewater is collected through the wastewater interface channel 101. As an optional implementation, the wastewater treatment device in this embodiment can be connected to water collection devices such as water collection ditches inside the tunnel to collect wastewater from these devices. After the wastewater enters, the hydraulic cylinder 201 drives the stop block 202 to move inside the inner cavity 104, controlling the closing of the outlet of the wastewater interface channel 101. When it opens, the wastewater is discharged into the centrifugal ring 1064. At this time, the drive motor 1062 is started, and the centrifugal ring 1064 is rotated by the mounting plate 1063 at the output end. Centrifugal force forces the wastewater through the through holes on the surface of the centrifugal ring 1064 and discharges it through the drain outlet 102. Mud and impurities remain inside the centrifugal ring 1064, thus completing the separation of impurities from the wastewater and improving treatment efficiency. After wastewater separation is completed, hydraulic cylinder 201 is reset to block the wastewater above. At the same time, drive motor 1062 stops working and hydraulic cylinder 106 is started. With the help of the moving plate 1061 on the output end surface, drive motor 1062 moves downward. The moving plate 1061 is limited by the limiting groove 105, so that the groove 1065 is disengaged from the inside of sleeve plate 107. At this time, drive motor 1062 is started again to drive centrifugal ring 1064 to rotate. With the help of centrifugal force, baffle 1067 on the surface of positioning shaft 1066 rotates, so that the mud and sand inside centrifugal ring 1064 fall into the surface of conical collar 108 and slide out through impurity discharge port 103. There is no need for manual cleaning at regular intervals, which facilitates subsequent processing. After cleaning, hydraulic cylinder 106 works again to move centrifugal ring 1064 on the surface of mounting plate 1063 upward along the inside of sleeve plate 107 to reset. Hydraulic cylinder 201 works to treat wastewater again.
