Description

Technical Field

[0001] The embodiments of this utility model belong to the field of submersible propeller technology, and more specifically, relate to a propeller support for sewage treatment. Background Technology

[0002] In modern wastewater treatment processes, especially in large aeration tanks, anaerobic tanks, or anoxic tanks, submersible jet mixers are required. These mixers generate a strong water flow through impeller rotation, agitating and propelling the mixed liquor within the tank. This prevents the settling of solids such as activated sludge and ensures a uniform distribution of dissolved oxygen, nutrients, and microorganisms, thereby enhancing the efficiency of biochemical reactions. To enable the jet mixer to operate stably at a specified depth and angle underwater, achieving an optimal hydraulic circulation field, a specially designed support system must be used to rigidly fix it to a predetermined position on the tank wall or bottom.

[0003] In existing technology, a common type of jet mixer mounting bracket is a cantilevered "L"-shaped structure. This bracket typically includes a vertical mounting base fixed to the tank wall by chemical anchors or pre-embedded parts, and a cantilever beam (usually H-beams or square tubing) extending horizontally from the base. The jet mixer body is then fixed to the end of this cantilever beam via flange connections or hoisting, suspending the jet mixer in the tank. The advantages of this design are its relatively simple structure, ease of installation, and ability to position the jet mixer in an effective working area away from the tank wall.

[0004] However, the aforementioned cantilever support system exhibits significant stability defects in practical applications. During operation, the thruster generates continuous and powerful axial reaction forces and high-frequency mechanical vibrations. These forces all act on the free ends of the cantilever beam, generating enormous bending moments and shear forces at the base of the support. Under long-term cyclic loading, this structure is highly susceptible to loosening of connecting bolts, fatigue cracking of welds, or permanent plastic deformation of the cantilever arm. Even slight deformation or loosening of the support can cause the thruster's thrust axis to deviate, leading to uneven stress distribution and further exacerbating the imbalance of the entire support system. This can ultimately result in support failure or thruster detachment, severely impacting the stability and safety of wastewater treatment equipment. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a flow actuator support for wastewater treatment. A compression support provides upward thrust to the flow actuator for support, and the inclined plane between the inclined push plate and the inclined guide plate converts a portion of the lateral reaction force on the flow actuator into a vertical thrust, pushing the inclined guide plate upwards. Then, a tension support provides downward tension to limit its movement. Under the combined action of the compression and tension supports, the lateral thrust on the flow actuator is reduced, thereby reducing the bending moment and shear force on the support and preventing structural deformation under long-term cyclic loading, which could lead to a decrease in support stability.

[0006] To achieve the above objectives, this utility model provides a flow propeller support for sewage treatment, including a compression support and a tension support disposed on a base at the bottom of the pool, and a vertical force component disposed between the base and the top platform of the pool. The compression support and the tension support are arranged side by side, and their bottom ends are anchored to the base by anchoring steel bars. The pressure-resistant support is equipped with a sliding plate and an inclined push plate. The flow pusher is fixed on the sliding plate, and the inclined push plate is also fixed on the sliding plate. The flow pusher and the inclined push plate slide synchronously with the sliding plate. The tensile support is provided with an inclined guide plate. The inclined push plate has an upward inclined surface at one end near the inclined guide plate, and correspondingly, the inclined guide plate has a downward inclined surface. The inclined surfaces of the inclined push plate and the inclined guide plate are opposite to and in contact with each other. The vertical force component includes a pole, the bottom end of which is anchored to the base by anchoring steel bars, and the top end is fixedly connected to the top platform by a fixing seat. A connecting rod is provided on the pole, and one end of the connecting rod is in contact with the compression support.

[0007] Furthermore, the pressure-resistant support is also provided with a pressure-resistant base plate, which is fixed to the top of the pressure-resistant support. Guide plates are provided on both sides of the pressure-resistant base plate along the axial direction of the flow generator. A guide groove is opened in the limiting plate, and a limiting baffle is provided at the end of the pressure-resistant base plate away from the tension support.

[0008] Furthermore, the two sides of the slide plate are provided in the guide grooves of the pressure-resistant base plate and slide along it. The slide plate is provided with a fixing frame, which fixes the pusher on the slide plate and supports it. The inclined push plates are used in pairs and are fixed to the top of the fixed frame. The two inclined push plates are respectively arranged on both sides of the fixed frame along the axial direction of the pusher.

[0009] Furthermore, the initial position of the slide plate is set at the limiting baffle at the end of the pressure-resistant base plate, with one end in contact with the limiting baffle. At this time, there is a small gap or just contact between the inclined push plate and the inclined guide plate, and there is no interaction force between the two.

[0010] Furthermore, the tensile support is characterized by having a tensile base plate fixed to the top of the tensile support, with a connecting column fixed to the top surface of the base plate, and the inclined guide plate located at the top of the connecting column. The connecting columns are used in pairs and are respectively connected to both sides of the inclined guide plate.

[0011] Furthermore, a limiting groove is opened at the top of the connecting column, and the top of the limiting groove is filled with elastic rubber. The vertical end of the inclined guide plate is provided with a protrusion corresponding to the shape of the limiting groove. The protrusion is located in the limiting groove, and the inclined guide plate has a short-range movement space along the limiting groove.

[0012] Furthermore, the feature is that an upper sliding seat and a lower sliding seat are fixed on the upright, the plane of the upper sliding seat is above the fixed frame, and the plane of the lower sliding seat is below the fixed frame; The upper and lower ends of the upper slide are baffles, and a sliding rod is provided between the two baffles. An upper slider is provided on the sliding rod of the upper slide. The upper and lower ends of the sliding seat are baffles, and a sliding rod is provided between the two baffles. A sliding block is provided on the sliding rod of the sliding seat.

[0013] Furthermore, both the upper and lower sliders are provided with connecting rings, and the connecting rods are arranged in pairs. One end of each connecting rod is rotatably connected to the connecting rings of the upper and lower sliders, respectively, and the other end is rotatably connected to the same force-distributing plate. An obtuse angle is formed between the two connecting rods.

[0014] Furthermore, the force-shaping plate has two connecting rings on one side near the upright, which are rotatably connected to the two connecting rods respectively, and rubber is embedded on the other side to form a vibration-damping surface.

[0015] Furthermore, the fixed frame is provided with a horizontal push column at one end near the vertical force component. The horizontal push column is columnar and passes through the gap between the two connecting columns to contact the vibration damping surface of the force component plate. The connecting column and the force-distributing plate are only in contact but not connected.

[0016] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects: 1. The thruster support of this utility model provides upward thrust to the thruster through a compression support. Under the action of the inclined plane between the inclined push plate and the inclined guide plate, a portion of the lateral reaction force on the thruster is converted into a vertical thrust, pushing the inclined guide plate upwards. Then, a tension support provides downward tension to limit its movement. This reduces the lateral thrust experienced by the thruster under the combined action of the compression and tension supports, thereby reducing the bending moment and shear force on the support and preventing structural deformation under long-term cyclic loading, which could lead to a decrease in support stability.

[0017] 2. In the flow promoter bracket of this utility model, when the flow promoter is activated, the reaction force of the sewage pushes the sliding plate towards the vertical force component. At this time, the sliding plate moves slightly, causing the inclined push plate to contact the inclined guide plate and generate compression. This generates a force that pushes the inclined guide plate upward, and the inclined guide plate compresses the elastic rubber in the limiting groove to eliminate the vertical force. This reduces the lateral shear force on the compression and tension supports, preventing structural instability caused by prolonged shear force.

[0018] 3. In the propeller bracket of this utility model, when the slide plate moves slightly towards the side closer to the vertical force component, it squeezes the force component plate to move, thereby distributing the lateral force to the upper and lower slides through the connecting rod. The upper and lower slides pull the upright in the up and down directions respectively, thereby converting part of the shear force applied to the upright into axial force and preventing the upright from deforming.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1 , 2 As shown, this utility model embodiment provides a flow propeller support for sewage treatment, including a compression support 3 and a tension support 4 disposed on a base 1 at the bottom of the tank, and a vertical force component 8 disposed between the base 1 and the top platform 2 of the tank. The compression support 3 and the tension support 4 are arranged side by side, and their bottom ends are anchored to the base 1 by anchoring steel bars. The compression support 3 is provided with a sliding plate 302 and an inclined push plate 304. The flow propeller 9 is fixed on the sliding plate 302, and the inclined push plate 304 is also fixed on the sliding plate 302. The flow propeller 9 and the inclined push plate 304 slide synchronously with the sliding plate 302. The tension support 4 is provided with an inclined guide plate 403. The inclined push plate 304 has an upward inclined surface near the inclined guide plate 403, and correspondingly, the inclined guide plate 403 has a downward inclined surface. The inclined surfaces of the inclined push plate 304 and the inclined guide plate 403 are opposite to and in contact with each other. The vertical force component 8 includes a support rod 801, the bottom end of which is anchored to the base 1 by anchoring steel bars, and the top end is fixedly connected to the top platform 2 by a fixing seat. A connecting rod 807 is mounted on the support rod 801, one end of which contacts the compression support 3. The compression support 3 provides upward thrust to the thruster 9 for support, and under the action of the inclined plane between the inclined push plate 304 and the inclined guide plate 403, a portion of the lateral reaction force on the thruster 9 is converted into vertical thrust, pushing the inclined guide plate 403 upward. Then, the tension support 4 provides downward tension to limit its movement. Under the combined action of the compression support 3 and the tension support 4, the thruster 9 experiences less lateral thrust, thereby reducing the bending moment and shear force on the support, preventing structural deformation under long-term cyclic loading and thus avoiding a decrease in support stability.

[0023] The positional relationship between the compression brace 3, the tension brace 4, and the vertical force component 8 is as follows: the tension brace 4 is located in the middle, and the compression brace 3 and the vertical force component 8 are located on both sides of the tension brace 4.

[0024] like Figure 3-5As shown, the pressure-resistant support 3 is also provided with a pressure-resistant base plate 301, which is fixed to the top of the pressure-resistant support 3. Guide plates are provided on both sides of the pressure-resistant base plate 301 along the axial direction of the flow pusher 9. A guide groove is opened in the guide plate. A limiting baffle is provided at the end of the pressure-resistant base plate 301 away from the tensile support 4. The two sides of the sliding plate 302 are located in the guide grooves of the pressure-resistant base plate 301 and slide along them. A fixing frame 303 is provided on the sliding plate 302, which fixes the flow pusher 9 to the sliding plate 302 and supports it. The inclined push plates 304 are used in pairs and are fixed to the top of the fixing frame 303. The two inclined push plates 304 are respectively located on both sides of the fixing frame 303 along the axial direction of the flow pusher 9.

[0025] The initial position of the slide plate 302 is set at the limiting baffle at the end of the pressure-resistant base plate 301, with one end in contact with the limiting baffle. At this time, there is a small gap or just contact between the inclined push plate 304 and the inclined guide plate 403, and there is no interaction force between the two.

[0026] The tensile support 4 is also provided with a tensile base plate 401, which is fixed to the top of the tensile support 4. A connecting column 402 is fixed to the top surface of the tensile base plate 401, and the inclined guide plate 403 is provided at the top of the connecting column 402. The connecting columns 402 are used in pairs and are respectively connected to both sides of the inclined guide plate 403.

[0027] As a further preferred embodiment, the top of the connecting column 402 is provided with a limiting groove, the top of which is filled with elastic rubber, and the vertical end of the inclined guide plate 403 is provided with a protrusion corresponding to the shape of the limiting groove. The protrusion is located in the limiting groove, and the inclined guide plate 403 has a short-range movement space along the limiting groove.

[0028] Understandably, when the flow booster 9 is activated, the reaction force of the sewage pushes the slide plate 302 towards the vertical force component 8. At this time, the slide plate 302 moves slightly, causing the inclined push plate 304 to contact the inclined guide plate 403 and compress it. This generates a force that pushes the inclined guide plate 403 upward, and the inclined guide plate 403 compresses the elastic rubber in the limiting groove to eliminate the vertical force. This reduces the lateral shear force on the compression support 3 and the tension support 4, preventing structural instability caused by prolonged shear force.

[0029] An upper slide block 804 and a lower slide block 805 are fixed on the upright 801. The plane of the upper slide block 804 is above the fixing frame 303, and the plane of the lower slide block 805 is below the fixing frame 303. The upper and lower ends of the upper slide block 804 are baffles, and a sliding rod is provided between the two baffles. An upper slide block 802 is provided on the sliding rod of the upper slide block 804. The upper and lower ends of the lower slide block 805 are baffles, and a sliding rod is provided between the two baffles. A lower slide block 803 is provided on the sliding rod of the lower slide block 805. Both the upper slide block 802 and the lower slide block 803 are provided with connecting rings. The connecting rods 807 are arranged in pairs. One end of each connecting rod 807 is rotatably connected to the connecting rings of the upper slide block 802 and the lower slide block 803, respectively, and the other end is rotatably connected to the same force-sharing plate 806. The two connecting rods 807 form an obtuse angle.

[0030] The force-distributing plate 806 has two connecting rings on one side near the upright 801, which are rotatably connected to the two connecting rods 807 respectively. The other side has an embedded rubber surface to form a vibration-damping surface. The fixing frame 303 has a horizontal push column 305 at one end near the vertical force-distributing component 8. This horizontal push column 305 is columnar and passes through the gap between the two connecting columns 402, contacting the vibration-damping surface of the force-distributing plate 806. The connecting columns 402 only contact the force-distributing plate 806, without actually connecting them.

[0031] As a further preferred embodiment, the lengths of the upper slider 802 and the lower slider 803 are both slightly less than or equal to the lengths of the corresponding sliding rods, so that when the force-distributing plate 806 is subjected to a lateral force, it decomposes the lateral force into vertical forces in the upper and lower directions, while avoiding large slippage and ensuring the stability of the support bracket for the thruster 9.

[0032] Understandably, when the slide plate 302 moves slightly towards the side closer to the vertical force component 8, it squeezes the force component plate 806 to move it, thereby distributing the lateral force to the upper slide plate 802 and the lower slide plate 803 through the connecting rod 807. The upper slide plate 802 and the lower slide plate 803 pull the upright rod 801 in the up and down directions respectively, thereby converting part of the shear force applied to the upright rod 801 into axial force and preventing the upright rod 801 from deforming.

[0033] In a preferred embodiment, when the propeller 9 is in use, a support column 5 is also provided on the top platform 2. The support column 5 is anchored to the top surface of the top platform 2, and a hanger 6 is provided on the top support column 5. The hanger 6 extends beyond the top platform 2, and a lifting assembly 7 is provided at its top. The lifting assembly 7 includes a steel wire rope and a winch located at the rear end of the steel wire rope. The front end of the steel wire rope is lowered from the hanger 6 onto the propeller 9 and connected to the lifting ring of the propeller 9.

[0034] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
