Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to prefabricated steel guide walls. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse, and it is increasingly becoming a part of the daily lives of ordinary people.

[0003] There are many ways to treat wastewater, among which the common one is the AAO process. This process involves anaerobic, anoxic, and aerobic treatment of wastewater, and is a commonly used secondary wastewater treatment process that has the function of simultaneous nitrogen and phosphorus removal. The existing anaerobic, anoxic, and aerobic tanks are generally constructed by pouring concrete.

[0004] However, when it is necessary to modify the wastewater treatment process, due to process requirements, it is necessary to add flow guiding equipment and stirring equipment in the reaction tank. Due to the special nature of the project, the reaction tank cannot be shut down and needs to be operated while waiting for water. If it is necessary to add flow guiding partitions in the reaction tank, the tank needs to be emptied, brick-concrete or reinforced concrete partitions need to be added, and the required equipment needs to be installed at the same time. The modification cycle is too long and affects normal production. Therefore, we proposed the prefabricated steel flow guiding wall. Summary of the Invention

[0019] Preferably, a connecting strip is fixedly connected between the ends of the two rotating blocks, and a fixing strip is fixedly connected to the end of the connecting strip. The fixing strip is fixedly connected to the upper surface of the mounting base, and a guide block is movably sleeved on the outer surface of the fixing strip.

[0020] Furthermore, the guide block is equipped with a lifting structure.

[0024] This invention discloses a prefabricated steel flow guide wall, which has the following beneficial effects:

[0025] 1. This prefabricated steel flow guide wall, with its central partition platform also serving as a maintenance platform, primarily functions to fix the central partition. The supporting steel frame and multiple mounting brackets are made of angle steel and are constructed using welding technology. The working surface during this fabrication process still relies on the floating bridge support plate. The supporting steel frame is assembled from sections of the same length. During installation, the corridor bridge component acts as a lifting support, and a portable hoist is used to lift the central partition platform into place. The tops of multiple hooks are respectively engaged with the upper surfaces of the three bottom beam frames. Simultaneously, two traction ropes are installed between the two sides of the supporting steel frame and the supporting frame, thus completing the installation of the central partition platform. After all the work, installation, and adjustments are completed and qualified, the floating bridge component will be removed, allowing the entire mechanism to enter its working state. The water in the pool will circulate along the central partition under the propulsion of six thrust units. Without interrupting the water supply, the original flow pattern of the pool is altered by adding a stirring device.

[0026] 2. Due to site limitations, cranes and other lifting equipment could not be used during the installation of this prefabricated steel guide wall. Therefore, a floating bridge assembly was adopted as the construction platform. The floating bridge mainly consists of a floating bridge support plate, multiple pontoons, and multiple fixing cables. The pontoons serve as the main supporting components for the floating bridge support plate. First, the pontoons are placed on the water surface in sequence and fixed to each other to ensure stability and even stress distribution. Next, the floating bridge support plate is fixed to the pontoons to form a unified whole. Finally, the four corners are fixed to the pool wall using multiple fixing cables, thus forming a stable operating platform. The floating bridge assembly can be freely adjusted in position to meet construction requirements.

[0027] 3. This prefabricated steel guide wall is constructed by integrally fabricating the fixed support and mounting base on the floating bridge support plate. Simultaneously, two rotating blocks at the top of the fixed support are rotatably connected to two fixed blocks on the side of the bottom beam frame via two pins, allowing the fixed support to rotate around the pins on the side of the bottom beam frame. After the fixed support is completed, it is placed flat. First, it is connected to the bottom beam frame via pins, then one end is slowly lowered into the water using ropes until it is vertically positioned and then fixed. After the fixed support is installed, the thrust unit is installed. The guide block installed on the back of the thrust unit is movably fitted onto the outer surface of the fixed strip. Then, the outer surface of the rotating shaft is fixedly connected to the lifting rope, so that the outer surface of the lifting rope successively abuts the limit shaft and the limit block, and the bottom end of the lifting rope is fixedly connected to the guide block. At this point, turning the rotating handle drives the rotating shaft to rotate, allowing the thrust unit to move up and down via the guide block and the fixed strip. The unit can then be successfully installed in place. Attached Figure Description

The floating bridge assembly 1, the three corridor bridge assemblies 2, the central partition platform 3, and the central partition 4 are all installed in anaerobic, anoxic, or aerobic tanks related to wastewater treatment.

[0041] The central partition platform 3 is positioned between the three corridor bridge components 2, and the central partition 4 is positioned below the central partition platform 3;

[0042] The corridor bridge component 2 includes a bottom beam frame 201 and a support frame 202.

A thrust unit 206 is provided on the upper surface of the mounting seats 205. The fixed supports 204 are equipped with an installation mechanism.

[0043] The water in the pool will circulate along the central partition 4 under the push of the six thrust units 206.

[0044] The central partition platform 3 can also serve as a maintenance platform. Its main function is to fix the central partition 4. The supporting steel frame 301 and multiple mounting frames 302 are made of angle steel and are also manufactured using welding technology. The working surface of this manufacturing process still relies on the floating bridge support plate 101. The supporting steel frame 301 is assembled from 6 sections of the same length. During the installation process, the corridor bridge component 2 serves as a lifting support. A portable hoist is used to lift the central partition platform 3 into place, and the tops of multiple hooks 303 are respectively hooked to the upper surface of the three bottom beam frames 201. At the same time, two traction ropes 304 are installed between the two sides of the supporting steel frame 301 and the supporting frame 202, thus completing the installation of the central partition platform 3. After all the work installation and adjustment are qualified, the floating bridge component 1 will be removed, so that the entire mechanism enters the working state. The water in the pool will circulate along the central partition 4 under the push of the six thrust units 206. Without stopping the water flow, the original pool flow pattern is changed by adding a stirring device.

[0045] The floating bridge assembly 1 includes a floating bridge support plate 101, multiple pontoons 102 and multiple fixing cables 103. The multiple pontoons 102 are fixedly installed below the floating bridge support plate 101, and the multiple fixing cables 103 are fixedly connected between the floating bridge support plate 101 and the pool walls on both sides.

[0046] During installation, due to limitations of the on-site construction environment, cranes and other lifting equipment could not be used. Therefore, a floating bridge component 1 was adopted as the construction platform. The floating bridge mainly consists of a floating bridge support plate 101, multiple floats 102, and multiple fixing cables 103. The multiple floats 102 serve as the main supporting components for the floating bridge support plate 101. First, the multiple floats 102 are placed on the water surface in sequence and fixed to each other to ensure stability and even force distribution. Next, the floating bridge support plate 101 and the multiple floats 102 are fixed together to form a unified whole. Finally, the four corners are fixed to the pool wall using multiple fixing cables 103, thus forming a stable operating platform. The floating bridge component 1 can be freely adjusted in position to meet construction requirements.

The supporting steel frame 301 is welded from multiple brackets, and the multiple mounting brackets 302 are welded to the bottom of the supporting steel frame 301. The partition 4 is installed at the bottom of the multiple mounting brackets 302.

[0049] Multiple hooks 303 are symmetrically fixedly connected to the upper surface of the supporting steel frame 301, and the tops of the multiple hooks 303 are respectively hooked to the upper surface of the three bottom beam frames 201. Two traction ropes 304 are installed between the two sides of the supporting steel frame 301 and the supporting frame 202.

[0050] A second anti-slip pad 305 is fixedly connected to the upper surface of the supporting steel frame 301, and multiple sections of guardrail 306 are fixedly connected to the upper surface of the supporting steel frame 301.

[0051] A transition steel pipe 401 is installed at the bottom of the intermediate partition 4.

[0052] The mounting mechanism includes two fixed blocks 5, which are fixedly connected to the side of the bottom beam frame 201. Two rotating blocks 501 are fixedly connected to one side of the top of the fixed support 204. The two rotating blocks 501 are rotatably connected to the two fixed blocks 5 respectively through two pins.

[0053] A connecting strip 502 is fixedly connected between the ends of the two rotating blocks 501, and a fixing strip 503 is fixedly connected to the end of the connecting strip 502. The fixing strip 503 is fixedly connected to the upper surface of the mounting base 205, and a guide block 504 is movably sleeved on the outer surface of the fixing strip 503. The guide block 504 is fixedly connected to the back of the thrust unit 206.

[0054] Furthermore, the guide block 504 is equipped with a lifting structure.

[0055] The lifting structure includes a lifting platform 6, which is fixedly connected to the top of the support frame 202. A protective frame 601 is fixedly connected to the upper surface of the lifting platform 6, and a ladder 602 is fixedly connected between the lifting platform 6 and the upper surface of the first anti-slip pad 203. A lifting support 603 is fixedly connected to the side of the protective frame 601, and a support bar 604 is fixedly connected to the bottom of the lifting support 603. The support bar 604 is fixedly connected to the front of the support frame 202.

[0056] A lifting seat 605 is fixedly connected to the top of the lifting support 603. A rotating shaft 606 is rotatably connected to the inner walls on both sides of the lifting seat 605. One end of the rotating shaft 606 extends outward through the outer wall of the lifting seat 605 and is fixedly connected to a rotating handle 607. A limiting shaft 608 is also fixedly connected to the inner walls on both sides of the lifting seat 605. A limiting block 609 is fixedly connected to the end of the lifting support 603.

[0057] A lifting rope is fixedly connected to the outer surface of the rotating shaft 606. The outer surface of the lifting rope is in series with the limiting shaft 608 and the limiting block 609, and the bottom end of the lifting rope is fixedly connected to the guide block 504.

[0058] The fixed support 204 and mounting base 205 are fabricated on the floating bridge support plate 101. Simultaneously, the two rotating blocks 501 at the top of the fixed support 204 are rotatably connected to the two fixed blocks 5 on the side of the bottom beam frame 201 via two pins, allowing the fixed support 204 to rotate around the pins on the side of the bottom beam frame 201. After the fixed support 204 is completed, it is placed flat. First, it is connected to the bottom beam frame 201 via pins, then one end is slowly lowered into the water using ropes until it is vertically positioned and then fixed. The fixed support 204 is then installed in place. Then, the installation of the thrust unit 206 begins. The guide block 504 installed on the back of the thrust unit 206 is movably sleeved on the outer surface of the fixing strip 503. Then, the lifting rope is fixedly connected to the outer surface of the rotating shaft 606, so that the outer surface of the lifting rope is in sequence in contact with the limiting shaft 608 and the limiting block 609, and the bottom end of the lifting rope is fixedly connected to the guide block 504. At this time, when the rotating handle 607 is turned, the rotating shaft 606 is driven to rotate, so that the thrust unit 206 can move up and down through the guide block 504 and the fixing strip 503. At this point, the unit can be successfully installed in place.

[0059] Working Principle: During installation, due to limitations of the on-site construction environment, cranes and other lifting equipment could not be used. Therefore, a floating bridge component 1 was adopted as the construction platform. The floating bridge mainly consists of a floating bridge support plate 101, multiple floats 102, and multiple fixing cables 103. The multiple floats 102 serve as the main supporting components for the floating bridge support plate 101. First, the multiple floats 102 are placed sequentially on the water surface and fixed together to ensure stability and even force distribution. Next, the floating bridge support plate 101 and the multiple floats 102 are fixed together to form a unified whole. Finally, the four corners are fixed to the pool wall using multiple fixing cables 103, thus forming a stable operating platform. The floating bridge component 1 can be freely adjusted in position to meet construction requirements.

[0060] After the installation of the floating bridge component 1 is completed, the fabrication and installation of the corridor bridge component 2 is the first process. First, the bottom beam frame 201 is fabricated and installed. The entire bottom beam frame 201 is made of channel steel and angle steel. Finally, the first anti-slip mat 203 is laid on the bottom beam frame 201. During the fabrication and installation process, scaffolding is erected with the floating bridge support plate 101 as support. After the bottom beam frame 201 is completed, the support frame 202 is installed. The columns of the support frame 202 are also made of angle steel. During the column fabrication process, the dome beam follows closely behind. After the column fabrication is completed, the dome beam is completed at the same time. Next, the stiffening plates are welded. After the stiffening plates are fixed, the side braces are welded. During this period, the corridor bridge frame will be corrected from time to time to ensure that the entire bottom beam frame 201 and support frame 202 meet the design requirements after they are completed. Finally, the lifting lugs of the traction rope 304 of the top partition platform 3 of the support frame 202 are welded.

[0061] The three bridge components 2 are manufactured and installed in the same way, and the spacing dimensions of the three bridge components 2 are corrected during the manufacturing and installation process;

[0062] After the installation of the corridor bridge component 2 frame is completed, the lifting platform 6 is welded. Then, the protective frame 601 is installed on the upper surface of the lifting platform 6, and the escalator 602 is installed between the lifting platform 6 and the upper surface of the first anti-slip pad 203. The lifting platform 6, the protective frame 601 and the escalator 602 are all made of angle steel. The treads of the escalator 602 are patterned anti-slip plates, and the guardrails of the escalator 602 are made of round tubes. At this time, the lifting support 603 and the support bar 604 are installed on the outer surfaces of the protective frame 601 and the support frame 202, respectively.

[0063] Then, the fixed support 204 and the mounting base 205 are fabricated on the floating bridge support plate 101. At the same time, the two rotating blocks 501 on the top of the fixed support 204 are rotatably connected to the two fixed blocks 5 on the side of the bottom beam frame 201 through two pins, so that the fixed support 204 can rotate around the pins on the side of the bottom beam frame 201. After the fixed support 204 is fabricated, it is in a flat state. First, it is connected to the bottom beam frame 201 through the pins, and then one end is slowly lowered into the water by rope until it is vertically positioned and then fixed.

[0064] After the fixed support 204 is installed in place, the installation of the thrust unit 206 begins. The guide block 504 installed on the back of the thrust unit 206 is movably sleeved on the outer surface of the fixed strip 503. Then, the lifting rope is fixedly connected to the outer surface of the rotating shaft 606, so that the outer surface of the lifting rope is in series with the limit shaft 608 and the limit block 609, and the bottom end of the lifting rope is fixedly connected to the guide block 504. At this time, when the rotating handle 607 is turned, the rotating shaft 606 is driven to rotate, so that the thrust unit 206 can move up and down through the guide block 504 and the fixed strip 503. At this point, the unit can be successfully installed in place.

[0065] The central partition platform 3 can also serve as a maintenance platform. Its main function is to fix the central partition 4. The supporting steel frame 301 and multiple mounting frames 302 are made of angle steel and are also manufactured using welding technology. The working surface of this manufacturing process still relies on the floating bridge support plate 101. The supporting steel frame 301 is assembled from 6 sections of the same length. During the installation process, the corridor bridge component 2 serves as the lifting support. A portable hoist is used to lift the central partition platform 3 into place, and the tops of multiple hooks 303 are respectively hooked onto the upper surface of the three bottom beam frames 201. At the same time, two traction ropes 304 are installed between the two sides of the supporting steel frame 301 and the supporting frame 202, thus completing the installation of the central partition platform 3.

[0066] Finally, the middle partition 4 is made of 40×30 square steel pipe welded together, with a width of 1 meter. The stainless steel plate is connected and fixed to the frame with rivets to make it a whole. The whole set of partitions consists of 36 pieces, which can be adjusted according to the actual site conditions. Each partition is connected by a snap-fit ​​connection. At the same time, the bottom of the middle partition 4 is treated with transition steel pipe 401 to prevent it from touching the bottom of the pool, so as not to damage the bottom structure of the pool.

[0067] After all the work installation and adjustments are completed and qualified, the floating bridge component 1 will be removed, allowing the entire mechanism to enter the working state. The water in the pool will circulate along the middle partition 4 under the push of the six thrust units 206. Without stopping the water flow, the original pool flow pattern will be changed by adding a stirring device.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
