Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of suspended partition wall technology, and more specifically, to a suspended partition wall for wastewater treatment ponds that can be constructed without interrupting water flow. Background Technology

[0002] The Biolake process, a common nitrogen removal process in wastewater treatment plants, does not strictly separate the anoxic and aerobic zones, which are relatively close together. The anoxic and aerobic zones are formed in the tank only by the alternating aeration and non-aeration of the aeration chain. Therefore, oxygen from the aerobic zone of the biological treatment tank can easily be carried into the anoxic zone, making it difficult to create an environment with extremely low dissolved oxygen concentration or anoxic conditions. With the increasing national standards for wastewater treatment discharge, it is still difficult for wastewater treatment plants using this process to meet the total nitrogen discharge standards. Therefore, in the subsequent upgrading and renovation process, the Biolake tank needs to be divided into anoxic and aerobic zones to meet the nitrogen removal requirements. In existing technologies, construction is generally carried out without interrupting water supply. A crane is used to lift the suspended partition wall and place it in the pool. However, during the construction process of placing the suspended partition wall using a crane, due to the large size of the suspended partition wall and the fact that it is only pulled into the pool by multiple ropes, it is difficult to maintain the stability of the suspended partition wall. This results in the suspended partition wall being placed tilted in the pool, which does not provide a good separation effect for the pool. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a suspended partition wall for construction without interrupting water flow in a sewage treatment tank, which solves the technical problem in the prior art where the stability of the suspended partition wall is too low when it is placed in the tank, resulting in the suspended partition wall being tilted in the tank and having a poor separation effect on the tank.

[0004] According to one aspect, at least one embodiment of this disclosure provides a suspended partition wall for construction without interrupting water flow in a sewage treatment tank, applied to the tank body, including a wall body, a slide rail provided on the tank body, an installation platform fixedly connected to one end of the wall body, the slide rail and the installation platform being detachably fixedly connected by bolts, and further including sliders, multiple quick-release hoisting connectors and floating support members, both ends of the wall body being fixedly connected to sliders that cooperate with the slide rails, the multiple quick-release hoisting connectors being disposed on the installation platform for stable connection with crane hooks, and the floating support members being disposed on the wall body for supporting the wall body.

[0005] Preferably, in order to quickly and securely connect the crane hook to the installation platform and facilitate disassembly and assembly, the quick-release lifting connector includes a connecting seat, a dovetail block, a lifting ring, and a locking component. One end of the connecting seat is fixedly connected to one end of the installation platform. The connecting seat has a dovetail groove that mates with the dovetail block. The dovetail block slides in the dovetail groove. One end of the dovetail block is fixedly connected to the lifting ring. The locking component is disposed in the connecting seat and is used to fix the connecting seat and the dovetail block.

[0006] Furthermore, in order to lock and fix the connecting seat and the dovetail block, the locking component includes a pin, an external thread, and a knob. Both the connecting seat and the dovetail block are provided with insertion holes. One end of the pin slides into the inner wall of the insertion hole. The external thread is fitted on the outer wall of the pin. The connecting seat is provided with a threaded hole that mates with the external thread. One end of the pin is coaxially fixedly connected to the knob.

[0007] Furthermore, in order to provide buoyancy to the wall and offset part of the weight of the wall borne by the crane, and to make the wall float in the pool, the floating support includes a fixed frame and multiple floats. The fixed frame is fixedly connected to both ends of the wall, one end of the fixed frame is fixedly connected to the other end of the installation platform, and multiple floats are arranged inside the fixed frame.

[0008] As a further aspect of this application, to prevent the pin from disengaging from the connector, the cross-sectional area of ​​the threaded hole is larger than the cross-sectional area of ​​the pin.

[0009] As a further improvement in this application, in order to allow water from the pool to enter the fixed frame and abut against the float, and to provide buoyancy to the wall in conjunction with the float, the fixed frame is L-shaped, and multiple through slots are provided at the other end of the fixed frame.

[0010] Based on the aforementioned solution, in order to increase the stability of the fixed frame, a plurality of reinforcing plates are fixedly connected to the other end of the fixed frame, and one end of the reinforcing plates is fixedly connected to the wall.

[0011] Furthermore, in order to limit the wall and fix it between the two guide rails, the slider is T-shaped.

[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the dovetail block is inserted into the dovetail groove by means of the cooperation of the slider, the slide rail, multiple quick-release lifting connectors and the floating support. By rotating the knob, one end of the pin is driven to rotate and insert into the insertion hole in the connector seat, and the external thread is engaged with the threaded hole. This fixes the connector seat and the dovetail block, so that the lifting ring is stably fixed above the installation platform, which is convenient for connection and cooperation with the crane hook. After the crane hook is connected to multiple lifting rings, it lifts the installation platform and wall, keeping them vertical. Then, it moves the installation platform so that the two sliders engage with the two guide rails. Driven by the crane, the wall and installation platform move longitudinally. The sliders guide and limit the wall, allowing it to be vertically installed in the pool, thus dividing the pool. When the multiple floats in the fixed frame come into contact with the pool water, they generate upward buoyancy for the installation platform, which can offset part of the weight of the wall borne by the crane. After the wall is installed in the pool, it can float in the pool. Finally, by using bolts to lock and fix the installation platform and guide rails, the wall can be prevented from floating up and down due to the buoyancy of the pool water, thus improving the stability of the wall.

[0022] like Figures 1-5As shown, this illustration depicts a suspended partition wall for a wastewater treatment tank constructed without interrupting water flow, applied to a tank body 1. The tank body 1 has a rectangular cross-section and includes a wall 2. Two slide rails 3 are symmetrically arranged within the two inner side walls of the tank body 1, and are on the same horizontal line. An installation platform 4 is fixedly connected to one end of the wall 2. The installation platform 4 is rectangular and its width is significantly greater than the width of the wall 2, providing greater buoyancy to the wall 2. The slide rails 3 and the installation platform 4 are detachably fixedly connected by bolts 5. The partition also includes a slider 6, multiple quick-release lifting connectors, and floating support components. Both ends of the wall 2 are fixedly connected to the slide rails. The sliders 6, which are matched with the wall 2, are used to limit the wall 2 and fix it between the two guide rails. The sliders 6 are T-shaped. By moving the wall 2, the two sliders 6 are respectively inserted into the two guide rails 3 and move longitudinally, which drives the installation platform 4 to move. When the top of the two guide rails 3 abuts against the bottom of the installation platform 4, the wall 2 is vertically set in the pool 1 and divides the pool 1. The installation platform 4 and the guide rails 3 are locked and fixed by bolts 5. This can prevent the wall 2 from floating up and down due to the buoyancy of the pool water. If the floating displacement is too large, when the worker stands on the installation platform 4, the worker may fall into the pool 1 and cause danger. like Figure 3 As shown, multiple quick-release lifting connectors are installed on the installation platform 4 for stable connection with the crane hook. In order to quickly and securely connect the crane hook to the installation platform 4 and facilitate disassembly and assembly, the quick-release lifting connectors include a connecting seat 7, a dovetail block 8, a lifting ring 10, and a locking component. One end of the connecting seat 7 is fixedly connected to one end of the installation platform 4. A dovetail groove 9 that mates with the dovetail block 8 is provided in the connecting seat 7. The dovetail block 8 and the dovetail groove 9 are slidably engaged. A lifting ring 10 is fixedly connected to one end of the dovetail block 8. The locking component is installed in the connecting seat 7 for fixing the connecting seat 7 and the dovetail block 8. like Figure 4As shown, to lock and fix the connecting seat 7 and the dovetail block 8, the locking components include a pin 11, an external thread 13, and a knob 15. Both the connecting seat 7 and the dovetail block 8 have insertion holes 12. One end of the pin 11 slides into the inner wall of the insertion hole 12, and the external thread 13 is fitted onto the outer wall of the pin 11. The connecting seat 7 has a threaded hole 14 that mates with the external thread 13. To prevent the pin 11 from disengaging from the connecting seat 7, the cross-sectional area of ​​the threaded hole 14 is larger than that of the pin 11. One end of the pin 11 is coaxially fixedly connected to the knob 15. By inserting the dovetail block 8 into the dovetail groove 9 on the connecting seat 7, and thus locking the connecting... The insertion holes 12 on the seat 7 and the dovetail block 8 are connected. The pin 11 is inserted into the insertion hole 12 in the dovetail block 8 through the threaded hole 14. When the external thread 13 abuts and aligns with the threaded hole 14, the knob 15 is rotated. The knob 15 drives the pin 11 and the external thread 13 on the outer wall of the pin 11 to rotate. The external thread 13 is threadedly engaged with the threaded hole 14. This causes one end of the pin 11 to rotate and insert into the insertion hole 12 in the connecting seat 7. One end of the knob 15 abuts against the connecting seat 7. This fixes the connecting seat 7 and the dovetail block 8, so that the lifting ring 10 is stably fixed above the installation platform 4, which is convenient for connection and cooperation with the crane hook. It should be added that the multiple connecting seats 7 are evenly distributed and small in size. The connecting seats 7 are made of high strength and high hardness material. While ensuring the stability of the hoisting, they will not affect the movement of the staff when they are inspecting the device on the installation platform 4. In addition, the bottom of the wall 2 is equipped with a soft connecting material section, which is made of soft PVC material. A stainless steel pressure strip is added to the bottom to ensure verticality. like Figure 2 and Figure 5As shown, the floating support is installed on the wall 2 to support the wall 2. In order to provide buoyancy to the wall 2 and offset part of the weight of the wall 2 borne by the crane, and to make the wall 2 float in the pool 1, the floating support includes a fixed frame 16 and multiple floats 17. The fixed frame 16 is fixedly connected to both ends of the wall 2. One end of the fixed frame 16 is fixedly connected to the other end of the installation platform 4. In order to increase the stability of the fixed frame 16, multiple reinforcing plates 19 are fixedly connected to the other end of the fixed frame 16. One end of the reinforcing plate 19 is fixedly connected to the wall 2. Multiple floats 17 are set inside the fixed frame 16. The floats 17 are plastic floats 17. In order to allow water from the pool 1 to enter the fixed frame 16 and come into contact with the floats 17, the floats 17 work together to support the wall 2. 17 provides buoyancy to the wall 2. The fixed frame 16 is L-shaped, and multiple through slots 18 are opened at the other end of the fixed frame 16. After the crane hook is connected to multiple lifting rings 10, it drives the installation platform 4 and the wall 2 to rise and maintain a vertical state. Then, it drives the installation platform 4 to move so that the two sliders 6 are respectively connected to the two slide rails 3. Under the drive of the crane, the wall 2 and the installation platform 4 move longitudinally. The sliders 6 guide and limit the wall 2. When the multiple floats 17 in the fixed frame 16 come into contact with the pool water, they can generate upward buoyancy for the installation platform 4, which can offset part of the weight of the wall 2 borne by the crane. After the wall 2 is installed in the pool 1, it can float in the pool 1. Then, the installation platform 4 and the slide rails 3 are locked and fixed by using bolts 5. Working principle: Before applying the suspended partition wall to the sewage treatment tank using a non-stop water supply construction method, the dovetail block 8 is inserted into the dovetail groove 9 on the connecting seat 7, and the insertion hole 12 on the connecting seat 7 and the dovetail block 8 are connected. The pin 11 is inserted into the insertion hole 12 in the dovetail block 8 through the threaded hole 14. When the external thread 13 abuts and aligns with the threaded hole 14, the knob 15 is rotated. The knob 15 drives the pin 11 and the external thread 13 on the outer wall of the pin 11 to rotate. The external thread 13 engages with the threaded hole 14, thus causing one end of the pin 11 to rotate and insert into the insertion hole 12 in the connecting seat 7. At the same time, one end of the knob 15 abuts against the connecting seat 7, thus fixing the connecting seat 7 and the dovetail block 8, so that the lifting ring 10 is stably fixed above the installation platform 4, facilitating connection and engagement with the crane hook. After the crane hook is connected to multiple lifting rings 10, it drives the installation platform 4 and the wall 2 to rise and remain vertical. Then, it drives the installation platform 4 to move so that the two sliders 6 are respectively connected to the two slide rails 3. Driven by the crane, the wall 2 and the installation platform 4 move longitudinally. The sliders 6 guide and limit the wall 2. When the multiple floats 17 in the fixed frame 16 come into contact with the pool water, they can generate upward buoyancy for the installation platform 4, which can offset part of the weight of the wall 2 borne by the crane. After the wall 2 is installed in the pool 1, it can float in the pool 1. Then, the installation platform 4 and the slide rails 3 are locked and fixed by using bolts 5 to prevent the wall 2 from floating up and down due to the buoyancy of the pool water. Finally, the knob 15 is turned to move the pin 11 out of the socket 12 and remove the dovetail block 8 and the lifting ring 10.
