Description

Technical Field

[0001] This utility model relates to a guide rod system for installing a flow generator with a round upper part and a square lower part, belonging to the field of water treatment equipment. Background Technology

[0002] Currently, many wastewater treatment plants adopt a sunken structure with greening backfill on the top of the tank, and openings are only made at the equipment locations, usually horizontal openings. The axial opening size of the flow promoter in the oxidation ditch process is not large (generally 1.5-2m), with load-bearing beams on both sides, and a horizontal flow channel.

[0003] In some projects, the civil engineering has been completed, or the initial flow promoter selection was too small, resulting in poor flow promotion effect. When it is necessary to replace it with a larger model of equipment, the axial dimension of the mounting hole on the top of the pool is too small. The axial dimension of the new equipment is often significantly larger than the existing opening size, making it impossible to install normally. Furthermore, the two sides of the mounting hole are vertically thick transverse load-bearing beams, making it impossible to expand the hole axially. The flow promoter cannot be placed in the normal installation method. Utility Model Content

[0004] This utility model provides a guide rod system for installing a propeller with a round upper part and a square lower part. Through the special guide rod system, the propeller can be temporarily turned around the guide rod during installation to avoid the load-bearing beam without falling off the guide rod.

[0005] The technical solution adopted by this utility model is a guide rod system for installing a flow promoter with a round upper part and a square lower part, including the top of the treatment tank and an opening on the top of the tank, which communicates with the interior of the treatment tank; a hoisting device is provided on one side of the opening on the top of the tank, and a flow promoter mounting platform is provided at the bottom of the treatment tank.

[0006] The propeller mounting guide rod system with an upper circle and a lower part also includes a guide rod and a guide rod guide component. The guide rod guide component is configured to cooperate with the guide rod and slide along the guide rod. The upper end of the guide rod is detachably connected to the lower end of the hoisting device.

[0007] The guide rod includes an upper section, a transition section, and a lower section, which are sequentially connected to form a rod shape.

[0008] The upper section of the guide rod has a circular radial cross-section, and the lower section of the guide rod has a square radial cross-section. The shape of the end of the guide rod transition section that connects to the upper section of the guide rod is matched with the radial cross-section of the upper section of the guide rod, and the shape of the end of the guide rod transition section that connects to the lower section of the guide rod is matched with the radial cross-section of the lower section of the guide rod.

[0009] The optimized guide rod system for mounting the above-mentioned upper circle and lower part of the impeller has a U-shaped guide rod. The guide rod is installed at the rear end of the impeller and the opening direction of the U-shaped opening is set away from the rear end face of the impeller.

[0010] The guide rod guide has a guide plate on each of the three side walls of the U-shaped opening.

[0011] The optimized guide rod system for installing the above-mentioned upper circular and lower flow generator uses a hand-operated lifting device with a bracket, the bracket of which is fixed to the top surface of the treatment tank; the upper end of the guide rod is detachably connected to the bracket of the lifting device.

[0012] The optimized guide rod system for mounting the above-mentioned upper circle and lower part of the flow generator has a surface shape that gradually transitions from a circle at one end to a square at the other end.

[0013] The optimized guide rod system for mounting the impeller with the upper circle below has an internal support tube inside the guide rod transition section, and the internal support tube is coaxially arranged with the guide rod transition section.

[0014] The optimized guide rod system for mounting the above-mentioned upper circle and lower part of the flow generator has a connector one and a connector two at both ends of the guide rod transition section;

[0015] One end of the connector is inserted into the end of the guide rod transition section facing the lower section of the guide rod and is welded and fixed to the guide rod transition section. The other end of the connector is inserted into the end of the lower section of the guide rod and is welded and fixed to the lower section of the guide rod.

[0016] One end of the second connector is inserted into the end of the guide rod transition section facing the upper section of the guide rod and welded to the upper section of the guide rod for fixation. The other end of the second connector is inserted into the end of the upper section of the guide rod and welded to the upper section of the guide rod for fixation.

[0017] The optimized guide rod system for the propeller installation at the top and bottom of the aforementioned circle has connector one and connector two arranged in a ring shape.

[0018] The two ends of the internal support tube are respectively inserted into the middle of connector one and connector two, and are welded and fixed to connector one and connector two.

[0019] The optimized guide rod system for mounting the propeller with the upper circle and lower part has anti-detachment limiting rods on both sides inside the U-shaped opening of the guide rod guide.

[0020] The advantages of this application are:

[0021] The technical solution proposed in this application is designed for retrofit projects, or situations where existing equipment is too small, resulting in poor flow propulsion, requiring replacement with a larger model of equipment, and the axial opening size on site is too small. It enables the smooth installation of a large-size flow propeller within a small axial opening size, meeting process requirements, without requiring modifications to the civil engineering structure.

[0022] In the technical solution of this application, a special guide rod system is used to allow the thruster to temporarily turn around the guide rod during installation, avoiding the load-bearing beam without detaching from the guide rod (it is not visible when descending underwater along the guide rod, and detaching from the guide rod is very dangerous). The blades turn to the normal direction after passing around the crossbeam, ensuring that the thruster with a large axial dimension can be installed normally, while ensuring the strength and rigidity of the guide rod.

[0023] The upper side of the guide rod is a round tube, and the lower side is a standard square tube. The middle is connected by a transition piece with a round upper part and a square lower part. This structure can ensure that the flow generator can turn smoothly along the guide rod without the risk of jamming or detachment. Attached Figure Description

[0042] The technical features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] As shown in the figure, this utility model is a guide rod system for installing a propeller with an upper circle and a lower circle, which is mainly used for the installation and use of large-diameter, low-speed propellers.

[0044] The treatment tank has an opening at the top, which connects to the internal space of the tank. For example... Figure 1 As shown, a hoisting device 1 is installed on one side of the opening at the top of the pool. The hoisting device 1 is mainly used to lift large-diameter low-speed propellers and assist in the installation and use of large-diameter low-speed propellers.

[0045] In one embodiment of this application, the lifting device 1 can be a hand-operated lifting device with a rotatable cantilever support. In other embodiments of this application, other lifting equipment such as a gantry crane can also be used. The selection of the lifting device 1 is for the purpose of facilitating lifting and relocation of the large-diameter, low-speed propeller.

[0046] The lower part of the support frame of the hoisting device 1 may have a base, and the base of the hoisting device 1 is fixed to the top surface of the treatment tank. The upper end of the guide rod is detachably connected to the support frame of the hoisting device 1. A detachable guide rod connector may be provided at the upper end of the guide rod. The specific structure can be a clamp with a support as shown in the figure. By disassembling the guide rod connector, the upper end of the guide rod can be detachably connected to the support frame of the hoisting device 1.

[0047] In this application, a flow promoter mounting platform is provided at the bottom of the treatment tank. The flow promoter mounting platform needs to be installed below the opening at the top of the tank. The lower end of the guide rod can be fixedly connected to the flow promoter mounting platform by means of bolts, welding, etc., or it can be detachably connected to the flow promoter mounting platform by existing common connectors. After the guide rod is connected and installed, it should be kept vertically aligned axially.

[0048] The guide rod guide 3 is a component installed at the tail end of the large-diameter, low-speed thruster for guiding during lifting and lowering. Its purpose is to allow the thruster to move up and down along the length of the guide rod, avoiding the load-bearing beam and preventing it from detaching from the guide rod (it is not visible when descending underwater along the guide rod, and detaching from the guide rod is very dangerous).

[0049] As shown in the figure, in one embodiment of this application, the main body of the guide rod guide 3 is U-shaped. The main body of the guide rod guide 3 can be formed into a U-shape by bending a steel plate. The outer bottom surface of the U-shape of the guide rod guide 3 is fitted to the rear end face of the jet generator and can be installed by bolt connection. After the jet generator is installed, the guide rod guide 3 is not removed.

[0050] As shown in the figure, in one embodiment of this application, a guide plate 301 is provided on each of the three side walls of the U-shaped opening of the guide rod guide 3. During the hoisting and descent of the propeller, the three guide plates 301 can fit against the surfaces of the upper section 201 and the lower section 203 of the guide rod to guide the descent of the propeller.

[0051] In addition, anti-detachment limiting rods 302 are respectively provided on both sides of the U-shaped opening of the guide rod guide 3. The anti-detachment limiting rods 302 serve as a safety measure to prevent the guide rod from detaching from the U-shaped interior of the guide rod guide 3.

[0052] In this application, the guide rod is set in the form of an upper circle and a lower circle. The upper circle makes it convenient for the propeller to rotate around the upper circle of the guide rod in the early stage of the hoisting process to adjust the angle to enter the opening at the top of the pool. In the later stage of the hoisting process, the lower square rod section of the upper circle guides the descent of the propeller and prevents the propeller from rotating in this section.

[0053] The specific guide rod includes an upper section 201, a transition section 202, and a lower section 203, which are connected sequentially to form a rod shape.

[0054] The radial cross-section of the upper section 201 of the guide rod is circular, and the radial cross-section of the lower section 203 of the guide rod is square. The shape of the end of the guide rod transition section 202 that connects to the upper section 201 of the guide rod is matched with the radial cross-section of the upper section 201 of the guide rod, and the shape of the end of the guide rod transition section 202 that connects to the lower section 203 of the guide rod is matched with the radial cross-section of the lower section 203 of the guide rod.

[0055] As shown in the figure, the surface shape of the guide rod transition section 202 gradually transitions from a circle at one end to a square at the other end.

[0056] In one embodiment of this application, in order to improve the strength of the guide rod transition section 202, an internal support tube 204 can be provided inside the guide rod transition section 202, and the internal support tube 204 is coaxially arranged with the guide rod transition section 202.

[0057] As shown in the figure, the guide rod transition section 202 has a first connector 205 and a second connector 206 at both ends. Both connectors 205 and 206 are annularly arranged. The two ends of the internal support tube 204 are inserted into the middle of connectors 205 and 206 respectively and welded to them. The annular outer surface shapes of connectors 205 and 206 are matched with the surface shape of the transition section 202, forming a continuously gradually changing smooth surface and preventing the flow actuator from getting stuck at this point.

[0058] One end of connector 205 is inserted into the end of guide rod transition section 202 facing the lower section 203 of guide rod and welded to the guide rod transition section 202 for fixation. The other end of connector 205 is inserted into the end of guide rod lower section 203 and welded to the guide rod lower section 203 for fixation. One end of connector 206 is inserted into the end of guide rod transition section 202 facing the upper section 201 of guide rod and welded to the guide rod upper section 201 for fixation. The other end of connector 206 is inserted into the end of guide rod upper section 201 and welded to the guide rod upper section 201 for fixation.

[0059] The working principle of this application will be explained below with reference to the accompanying drawings:

[0060] 1. Remove the connector between the top guide rod and the crane base (guide rod connector, see...). Figure 5 );

[0061] 2. Rotate the impeller at a certain angle to ensure that its guide shoe can be inserted into the circular tube section on the upper side of the guide rod, and that the blades can be vertically inserted into the equipment opening. Figure 6 , 7 ).

[0062] 3. Lower the jet generator along the guide rod and promptly install the guide rod connector into place. Figure 8 , 9 10);

[0063] 4. When the impeller blades can pass over the lower edge of the crossbeam, rotate the impeller to the working direction. Figure 11 , 12 13).

[0064] 5. Continue lowering the thruster along the guide rod to the working position. Figure 14 ).

[0065] 6. To lift the jet generator, simply reverse the steps described above.

[0066] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
