Description

Technical Field

[0001] The utility model relates to the technical field of paddle type mixers, in particular to a paddle type mixer for sewage treatment. Background Art

[0002] The paddle mixer used in sewage treatment is a common equipment, which is mainly used to mix and stir the suspended matter in sewage, promote the sedimentation of sludge in water and the solid-liquid separation. The paddle mixer mixes and stirs the suspended matter in the water body through rotating blades or stirring paddles, making it easier to combine with the sludge. Stirring can prevent the accumulation of bottom sediments and promote uniform sedimentation and dispersion of suspended matter. Through mechanical stirring, it can also effectively improve the compactability of sludge, which is helpful for the subsequent sludge treatment process. The paddle mixer is usually composed of a motor, a reducer, stirring blades, etc. The design and layout of the stirring blades are crucial to the stirring effect.

[0003] At present, when installing the mixing blades of a paddle mixer, the motor is usually fixed in position using a bracket compatible with the mixer. However, the position of the mounting hole on some mixers does not correspond to the position on the bracket, so adjustment and installation are impossible. Moreover, the bracket of the corresponding size can only be installed with the mixer that matches it, unless the bracket is re-drilled for use and installation. This process is relatively cumbersome and will increase the difficulty of installation. At the same time, flanges are respectively assembled on the ends of the coupling and the mixing blades, and then the two flanges are installed. However, the impeller angle is prone to deflection during installation, and the verticality of the impeller and the rotating shaft is prone to deviation. It is easy to loosen after running for a long time. For this reason, we propose a paddle mixer for sewage treatment. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In an embodiment of the utility model, a paddle mixer for sewage treatment includes a mounting frame 1 and a coupling 3 arranged on the lower end surface of the mounting frame 1, a stirring blade 4 is installed at the end of the coupling 3, and side walls of the mounting frame 1 away from each other are installed with electric telescopic slides 6, and ends of the two electric telescopic slides 6 away from the mounting frame 1 are installed with mounting plates 8, and the outer circumferential surface of the coupling 3 is installed with a fixed clamping ring 21, and the outer circumferential surface of the fixed clamping ring 21 is installed with multiple auxiliary calibration components 2; the number of auxiliary calibration components 2 is not limited. In this embodiment, preferably, the number of auxiliary calibration components 2 is two, and the two auxiliary calibration components 2 are symmetrically arranged on the outer circumferential surface of the fixed clamping ring 21 with the coupling 3 as the midpoint, which is conducive to the calibration of the stirring blade 4 during the initial installation.

[0022] Specifically, a motor connected to a coupling 3 is installed on the upper end surface of the mounting frame 1, grooves are respectively provided on both sides of the mounting frame 1, and a first rotating shaft 5 is fixedly connected inside the grooves, and an end of the electric telescopic slide plate 6 is movably connected to the outer circumferential surface of the first rotating shaft 5, and a second rotating shaft 7 connected to a mounting plate 8 is installed on the other end of the electric telescopic slide plate 6, circular grooves are respectively provided on both sides of the electric telescopic slide plate 6, and the inside of the circular groove is rotatably connected to the second rotating shaft 7, and the surface of the second rotating shaft 7 is fixedly connected to the mounting plate 8. Secondly, since the positions of the mounting holes at the upper ends of different types of mixing barrels are different, by adjusting the inclination angle between the electric telescopic slide plate 6 and the mounting frame 1, and also by adjusting the length of the electric telescopic slide plate 6, the mounting holes on the mounting plate 8 can be made to correspond to the positions of the mounting holes on the mixing barrel, so that the mounting frame 1 for fixing the motor can adapt to mixing barrels of different types, thereby improving the adjustable effect and adaptability of the section mounting frame 1.

[0023] The auxiliary calibration assembly 2 includes an extended oblique rod 22 arranged on the outer circumference of the fixed clamping ring 21, a fixed plate 23 is installed at the end of the extended oblique rod 22, a sliding cross bar 24 is arranged through the vertical side wall of the fixed plate 23, a connecting square plate 26 is installed at the through end of the sliding cross bar 24, a third spring 25 is movably sleeved on the outer circumference of the sliding cross bar 24, whose ends are respectively in contact with the fixed plate 23 and the connecting square plate 26, an anti-slip ring is installed at the end of the sliding cross bar 24 away from the connecting square plate 26, and an external thread is provided on the end of the outer circumference of the sliding cross bar 24 close to the connecting square plate 26, and a calibration half ring 27 for auxiliary installation and calibration of the stirring blade 4 is installed on the end surface of the connecting square plate 26 away from the sliding cross bar 24.

[0024] Specifically, an internal threaded hole is provided on the surface of the fixed plate 23 for the sliding cross bar 24 to pass through, and the external thread arranged on the outer peripheral surface of the sliding cross bar 24 is threadedly connected with the internal threaded hole on the fixed plate 23. After the preliminary calibration during the installation of the mixing blade 4 is completed, the installation operation can be performed by one person alone during the entire operation, thereby avoiding the limitation that one person cannot operate the operation. The time spent on alignment can be reduced during the entire operation, greatly improving the efficiency of the installation. At the same time, the internal and external threads can contact when the anti-slip ring on the sliding cross bar 24 is pulled, and the sliding cross bar 24 can be rotated so that the internal threaded hole on the fixed plate 23 limits the lateral movement of the sliding cross bar 24. At this time, the calibration half ring 27 will not contact the surface of the mixing blade 4, which will not affect the normal rotation of the mixing blade 4.

[0025] See also Figure 2 In one embodiment, in this embodiment, preferably, a first spring 9 is provided on the upper end surface of the mounting plate 8, and an extension plate 10 connected to the surface of the electric telescopic slide plate 6 is installed at the end of the first spring 9.

[0026] Specifically, since the mounting plate 8 can rotate along the second rotating shaft 7 on the electric telescopic slide plate 6, when the electric telescopic slide plate 6 is adjusting the angle and length, the inclination angle of the mounting plate 8 can also be adjusted at any time, so that the bottom surface of the mounting plate 8 always maintains a larger contact area with the contact surface of the mounting hole on the mixing barrel. At the same time, the cooperation between the first spring 9 and the extension plate 10 can apply downward pressure to one end of the mounting plate 8, which can further ensure that the bottom surface of the mounting plate 8 is always in a fit state with the installation position. The adjustment of the mounting hole position can be effectively realized during the entire operation, thereby improving the overall installation adaptability and making it more practical.

[0028] The working principle and use process of the utility model are as follows: during operation, the operator controls the electric telescopic slides 6 on both sides to rotate on the surface of the first rotating shaft 5 connected to the mounting frame 1, thereby making the mounting plate 8 installed on the second rotating shaft 7 at the bottom of the electric telescopic slide 6 and the mounting hole position at the installation site adapt and align. During the adaptation process, the first spring 9 fixedly connected to the top of the mounting plate 8 is elastically bent at the bottom of the extension plate 10 fixedly connected to the side of the electric telescopic slide 6, thereby ensuring that the mounting plate 8 is in a fit state with the installation position.

At the same time, the stirring blade 4 is aligned with the inside of the two calibration semi-rings 27 and inserted. During the insertion process, the sliding cross bar 24 fixedly connected to the sides of the two calibration semi-rings 27 slides outward inside the fixed plate 23, and in the sliding process, the connecting square plate 26 fixedly connected to the surface of the sliding cross bar 24 squeezes the third spring 25 fixedly installed on the side of the fixed plate 23, and then under the action of the elastic potential energy of the third spring 25 itself, the calibration semi-ring 27 can be fitted on the surface of the stirring blade 4 to form a preliminary calibration auxiliary installation.
