Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment mixers, specifically to a sewage treatment mixer with adjustable mixing blade angle. Background Technology

[0002] The impeller-driven wastewater treatment mixer is a core piece of equipment in wastewater treatment processes to achieve mixing, mass transfer, and enhanced reaction. It drives the impeller to rotate and mechanically disturb the wastewater and reaction agents, providing the necessary hydraulic conditions for key processes such as pollutant degradation, mud-water separation, and reagent reaction. It is widely used in the treatment of urban domestic sewage, industrial wastewater (such as chemical, printing and dyeing, and food processing wastewater), and livestock and poultry breeding wastewater.

[0003] In existing technologies, mixers drive the impeller to rotate via a motor drive shaft, converting mechanical energy into the kinetic energy of the fluid. When the impeller rotates, the blade surface and the fluid generate relative motion, forming shear force, which causes the fluid to generate laminar or turbulent motion. Through the high shear force at the edge of the impeller, large particles or agglomerates are broken into smaller particles, increasing the contact area and promoting chemical reactions or biodegradation. Typically, the impeller blades are blade-shaped, such as straight blades or oblique blades.

[0004] However, there are some drawbacks: when sewage flows into the casing of the mixing blades of the mixer, the mixing range of traditional mixing blades is limited because they are connected in a fixed manner. When sewage carrying various impurities such as suspended particles, fibers, and lumpy sludge flows into the casing of the mixing blades, the mixing range of traditional mixing blades is fixed from the beginning of the design because they are connected to the drive components in a fixed manner. It is impossible to adjust the blade angle according to the suspended particles, fibers, and lumpy sludge after the sewage flows in. The fixed-angle mixing blades have difficulty contacting the sludge in some sewage, which may lead to uneven mixing in some areas. This may also cause some large particles to fail to be sheared and broken into smaller particles, ultimately reducing the overall effect of sewage treatment. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a sewage treatment mixer with adjustable impeller angle, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a sewage treatment mixer with adjustable impeller angle, including a shell and a hollow annular base plate disposed at one end of the shell. The shell contains an impeller body and a rotating ball. A bracket is fixedly connected to the inner port of one end of the hollow annular base plate. A fixing plate is fixedly installed at one end of the hollow annular base plate. An angle adjustment component is provided at one end of the impeller body, which is used to adjust the angle of the impeller body. The angle adjustment component includes a column, and a hemisphere is fixedly installed at the lower end of the column. A rotating hole is opened through the inner wall of the outer wall of the hemisphere, and the lower end of the column is located inside the hemisphere.

[0007] Furthermore, a support plate is fixedly connected to the lower end of the column near the outer wall, a bottom plate is fixedly installed on the upper end of the support plate, the bottom plate is slidably sleeved on the outer wall of the column, and a movable sleeve is fixedly sleeved on the upper end of the outer side of the column near the bottom plate.

[0008] Furthermore, the outer wall of the movable sleeve is fixedly connected with corner brackets, the upper end of the corner brackets is fixedly connected with movable guide rods, the upper end of the movable guide rods is rotatably fitted with fixed pins, the two ends of the fixed pins are fixedly fitted with movable frames, and one end of the movable frames is fixedly installed with connecting guide rods.

[0009] Furthermore, a threaded block is fixedly connected to the outer wall of the movable sleeve, and a screw is rotatably sleeved inside the threaded block. A connecting rod is fixedly connected to the upper end of the screw, and a micro motor is fixedly installed at the upper end of the connecting rod. An inner support plate is fixedly installed at the lower end of the micro motor. The inner wall of one end of a spherical cover is fixedly sleeved on the outer wall of the inner support plate. The micro motor and the inner support plate are located inside the spherical cover, and one end of the spherical cover is fixedly installed at one end of a hemisphere. Furthermore, an installation cylinder is fixedly connected to the upper part of the outer wall of the column, a bearing sleeve is fixedly sleeved inside the installation cylinder, a rotating column is fixedly sleeved inside the bearing sleeve, and the outer wall of the rotating column is rotatably sleeved inside the rotating hole of the hemisphere.

[0010] Furthermore, a connecting guide rod is fixedly sleeved inside the rotating column. One end of the connecting guide rod is fixedly installed at one end of the stirring blade body. An external corner plate is fixedly installed at one end of the stirring blade body. One side of the external corner plate is fixedly installed at one end of the rotating column, and one side of the external corner plate contacts the outer wall of the hemisphere and the spherical cover.

[0011] Furthermore, the bracket has a rotating shaft rotatably connected inside. One end of the rotating shaft is fixedly installed on one end of the outer wall of the spherical cover. A fixing plate is fitted onto one end of the rotating shaft. One end of the fixing plate is fixedly installed on one end of the hollow annular base plate. A fixing sleeve is fixedly installed on one end of the fixing plate. A servo motor is fixedly installed on one end of the fixing sleeve. The output shaft of the servo motor is drivenly connected to one end of the rotating shaft. The rotating shaft is fitted inside the fixing sleeve.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: This invention utilizes an angle adjustment component. A micro-motor output shaft drives a connecting rod and a screw to rotate, causing the threaded block to move up and down. The up-and-down movement of the movable sleeve causes the angle bracket block to move synchronously. This, in turn, pulls or pushes the movable frame via a movable guide rod. The movable frame is fixed to the connecting guide rod, which passes through a rotating column. The rotating column is mounted on a hemisphere through a rotating hole and can rotate around the axis of the rotating hole. The pushing and pulling of the movable frame is converted into the rotational motion of the rotating column, ultimately causing the main body of the stirring blade, fixed to the rotating column, to deflect around the axis of the rotating hole. This achieves angle adjustment of the stirring blade. Compared to traditional stirring blades, which are fixed and have a limited stirring range, this invention allows for adjustment of the blade angle based on the suspended particles, fibers, and lumpy sludge present in the wastewater. This avoids the problem of fixed-angle stirring blades failing to contact sludge in certain parts of the wastewater, thus preventing uneven stirring and ensuring that large sludge particles are not broken down into smaller particles, ultimately reducing the overall effectiveness of wastewater treatment.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example 1: Reference Figures 1 to 5 This is the first embodiment of the present invention, which discloses a wastewater treatment mixer with adjustable impeller angle. It includes a shell 1 and a hollow annular base plate 2 disposed at one end of the shell 1. The shell 1 is provided with an impeller body 4 and a rotating ball 6. The rotating ball 6 rotates, which in turn drives the impeller to rotate. A bracket 5 is fixedly connected to the inner port of one end of the hollow annular base plate 2. A fixing plate 32 is fixedly installed at one end of the hollow annular base plate 2. An angle adjustment component 7 is provided at one end of the impeller body 4. The angle adjustment component 7 is used to adjust the angle of the impeller body 4. The impeller with different angles pushes wastewater in different directions, stirs in different depths, and has different shear forces. When the impeller angle is gentler, the stirring range is larger and it is suitable for diluting wastewater. When the angle is steeper, the shear force is stronger and it is suitable for breaking up concentrated sludge. Wastewater mixers are common in the prior art and will not be described in detail here. The angle adjustment assembly 7 includes a column 71, with a hemisphere 61 fixedly installed at the lower end of the column 71. A rotating hole 63 is opened through the inner wall of the outer wall of the hemisphere 61. The lower end of the column 71 is located inside the hemisphere 61. A support plate 718 is fixedly connected to the lower end of the column 71 near the outer wall. A bottom plate 78 is fixedly installed at the upper end of the support plate 718. The inner wall of the bottom plate 78 is slidably fitted onto the outer wall of the column 71. A movable sleeve 713 is fixedly fitted onto the outer side of the column 71 near the upper end of the bottom plate 78. Angle bracket blocks 712 are fixedly connected to the outer wall of the movable sleeve 713. The micro motor 72 is the power source, and its output torque is transmitted to the screw 74 through the connecting rod 73. The screw 74 and the threaded block 719 form a threaded engagement. When the screw 74 rotates, the threaded block 719 will move up and down along the axial direction of the screw 74. Since the threaded block 719 is fixed to the movable sleeve 713, and the movable sleeve 713 is fitted on the column 71, the column 71 restricts the rotational freedom of the movable sleeve 713, which can only slide up and down. The upper end of the corner block 712 is fixedly connected to the movable guide rod 711. The upper end of the movable guide rod 711 is rotatably fitted with a fixed pin 710. The two ends of the fixed pin 710 are fixedly fitted with movable frames 79. One end of the movable frame 79 is fixedly installed with a connecting guide rod 714.

[0019] A threaded block 719 is fixedly connected to the outer wall of the movable sleeve 713. A screw 74 is rotatably sleeved inside the threaded block 719. A connecting rod 73 is fixedly connected to the upper end of the screw 74. A micro motor 72 is fixedly installed at the upper end of the connecting rod 73. An inner support plate 77 is fixedly installed at the lower end of the micro motor 72. The inner wall of the inner support plate 77 is fixedly sleeved with the inner wall of one end of the ball cover 62. The micro motor 72 and the inner support plate 77 are located inside the ball cover 62. One end of the ball cover 62 is fixedly installed at one end of the hemisphere 61. An installation cylinder 76 is fixedly connected to the upper part of the outer wall of the column 71. A bearing sleeve 75 is fixedly sleeved inside the installation cylinder 76. A rotating column 717 is fixedly sleeved inside the bearing sleeve 75. The outer wall of the rotating column 717 is rotatably sleeved inside the rotating hole 63 of the hemisphere 61. A connecting guide rod 714 is fixedly sleeved inside the rotating column 717. One end of the moving sleeve 713 is fixedly installed at one end of the stirring blade body 4. An external angle plate 715 is fixedly installed at one end of the stirring blade body 4. One side of the external angle plate 715 is fixedly installed at one end of the rotating column 717. One side of the external angle plate 715 contacts the outer wall of the hemisphere 61 and the ball cover 62. The up and down movement of the moving sleeve 713 will drive the angle bracket block 712 to move synchronously, and then pull or push the movable frame 79 through the movable guide rod 711. The movable frame 79 is fixed to the connecting guide rod 714, and the connecting guide rod 714 passes through the rotating column 717. The rotating column 717 is mounted on the hemisphere 61 through the rotating hole 63 and can rotate around the axis of the rotating hole 63. The pushing and pulling of the movable frame 79 will be converted into the rotational motion of the rotating column 717, which will eventually drive the stirring blade body 4 fixed to the rotating column 717 to deflect around the axis of the rotating hole 63, thereby realizing the adjustment of the stirring blade angle.

[0020] In use, first determine the direction of adjustment of the mixing blades, such as the mixing range and shear strength, based on the sewage treatment requirements. The upward or downward deflection angle value is determined by the output shaft of the micro motor 72, which drives the connecting rod 73 and the screw 74 to rotate. If the mixing blade body 4 needs to deflect upward, control the micro motor 72 to rotate forward. The screw 74 rotates, causing the threaded block 719 to move the moving sleeve 713 upward. The angle bracket block 712 moves upward, and the movable guide rod 711 pushes the movable frame 79 upward, causing the rotating column 717 to rotate around the rotating hole 63, which drives the mixing blade body 4 to deflect upward synchronously. If the mixing blade body 4 needs to deflect downward, control the micro motor 72 to rotate in reverse. The moving sleeve 713 moves downward, and the movable guide rod 711 pushes the movable frame 79 downward. The rotating column 717 rotates downward, achieving the downward deflection of the blades.

[0021] It is worth noting that the up-and-down movement of the movable sleeve 713 will drive the corner bracket block 712 to move synchronously, which in turn will pull or push the movable frame 79 through the movable guide rod 711. The movable frame 79 is fixed to the connecting guide rod 714, and the connecting guide rod 714 passes through the rotating column 717. The rotating column 717 is mounted on the hemisphere 61 through the rotating hole 63 and can rotate around the axis of the rotating hole 63. The pushing and pulling of the movable frame 79 will be converted into the rotational motion of the rotating column 717, which will eventually drive the stirring blade body 4 fixed to the rotating column 717 to deflect around the axis of the rotating hole 63, thereby realizing the adjustment of the stirring blade angle.

[0022] Example 2: Reference Figures 1 to 3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a rotating shaft 33 is rotatably sleeved inside the bracket 5. One end of the rotating shaft 33 is fixedly installed on one end of the outer wall of the ball cover 62. A fixing plate 32 is sleeved on one end of the rotating shaft 33. One end of the fixing plate 32 is fixedly installed on one end of the hollow annular base plate 2. A fixing sleeve 31 is fixedly installed on one end of the fixing plate 32. A servo motor 3 is fixedly installed on one end of the fixing sleeve 31. The output shaft of the servo motor 3 is drivenly connected to one end of the rotating shaft 33. The rotating shaft 33 is sleeved inside the fixing sleeve 31.

[0023] When in use, the servo motor 3 starts after the power is turned on, and its output shaft starts to rotate. The output shaft transmits power to the rotating shaft 33 connected to it, causing the rotating shaft 33 to rotate synchronously. Since one end of the rotating shaft 33 is fixedly installed on the outer wall of the ball cover 62, the rotation of the rotating shaft 33 will directly drive the ball cover 62 to rotate around the axis of the rotating shaft 33, further driving the ball and the rotating ball to rotate, thereby driving the stirring blade body 4 to rotate inside the outer shell 1.

[0024] The remaining structure is the same as that in Example 1.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
