Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to a rotary drum biological filler treatment device. Background Art

[0002] The biofilm method is a traditional biodegradation method for treating wastewater. The biofilm method uses microorganisms to aggregate and attach on the surface of the filler to form a biofilm. The biofilm comes into contact with the wastewater to be treated, thereby degrading the organic matter in the wastewater and purifying the wastewater.

[0003] At present, the more mature biofilm methods include biological packing turntable, biological contact oxidation method, biological filter and biological fluidized bed. In the application process of the biological packing turntable, the turntable is driven by electricity to improve the efficiency of oxygen mass transfer on the biofilm fixed on the turntable. This method is simple to operate and has low energy consumption. However, under different ambient temperatures, the growth rate, physiological characteristics and biological activity of microorganisms on the biological packing turntable are affected by the immersion rate. The working height of the existing biological packing turntable is fixed and cannot adapt to various working conditions, so further improvement is needed. Utility Model Content

[0004] In order to improve the adaptability of the biological filler rotating disk, the present application provides a rotating drum biological filler processing device.

[0005] The present application provides a rotary drum biological filler treatment device that adopts the following technical solution:

[0006] A rotary drum biological filler processing device comprises a tank body, a support frame vertically slidably connected to the inner wall of the tank body, a mounting shaft rotatably connected to the support frame, a biological filler turntable mounted on the mounting shaft, and a rotating mechanism arranged on the support frame to drive the mounting shaft to rotate. The tank body is provided with a lifting drive mechanism for driving the support frame to lift and lower to adjust the height position of the support frame.

[0007] By adopting the above technical solution and adding a lifting drive mechanism, it is convenient to adjust the height position of the support frame according to different working conditions, thereby adjusting the immersion rate of the biological filler turntable, improving the sewage treatment effect and improving the adaptability of the biological filler turntable.

[0008] Preferably, the lifting drive mechanism includes an adjusting screw rotatably connected to the pool body and threadedly penetrated through the slider, and a driving motor arranged on the pool body to drive the adjusting screw to rotate, and the axial direction of the adjusting screw is arranged vertically.

[0009] By adopting the above technical solution, the drive motor is started to drive the adjustment screw to rotate, thereby driving the slider to slide along the height direction of the pool body, so as to adjust the height position of the support frame according to different working conditions, thereby adjusting the immersion rate of the biological filler turntable.

[0015] By adopting the above technical solution, when the limiting sleeve slides to the corresponding position, when the sliding position of the limiting sleeve is limited by the limiting member, the elasticity of the spring itself is used to limit the distance between adjacent biological filler turntables, which can speed up the adjustment of the distance between adjacent biological filler turntables and reduce the time spent on limiting by placing limiting blocks of corresponding sizes between adjacent biological filler turntables.

[0016] Preferably, the outer wall of the mounting shaft is provided with limiting holes in the radial direction, a plurality of limiting holes are provided and distributed along the axial direction of the mounting shaft, the limiting member is a limiting bolt threadedly penetrated through the limiting ring sleeve, and the end of the limiting bolt is inserted into the limiting hole.

[0017] By adopting the above technical solution, when the sliding sleeve slides to the corresponding position, the limiting bolt slides through the limiting sleeve and is threadedly connected to the corresponding limiting hole to change the spacing between adjacent biological filler turntables.

[0019] By adopting the above technical solution, the installation shaft can be disassembled from the support frame by setting the connecting rod and the connecting block, so as to be used for disassembling the biological filler turntable slidably sleeved on the installation shaft, or to reduce or increase the number of biological filler turntables when changing the spacing between the biological filler turntables.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. By adding a lifting drive mechanism, it is convenient to adjust the height position of the support frame according to different working conditions, thereby adjusting the immersion rate of the biological filler turntable, improving the sewage treatment effect and improving the adaptability of the biological filler turntable.

[0022] 2. By providing an adjustment component, the spacing between adjacent biological filler turntables located on the same installation axis can be adjusted to improve the processing efficiency of microorganisms. BRIEF DESCRIPTION OF THE DRAWINGS
