Embodiment 1

[0029] see Figure 1-4 As shown, a high-efficiency microbubble dissolving device according to the present invention includes a tank body 1; one end of the tank body 1 is provided with a water inlet pipe 2 and an air inlet pipe 3, and the end of the tank body 1 away from the water inlet pipe 2 is arranged There is a water outlet pipe 4, and the middle part of the end face of the tank body 1 is rotatably connected with a rotating rod 5, and the end of the rotating rod 5 close to the water inlet pipe 2 is fixedly connected with a number of spiral fan blades 6; although the existing dissolved air tank body 1 The passing water flow can be cut through the air-dissolving rod 8 on the inner wall, so as to promote the integration of air into the water, but the cutting effect and cutting area of ​​the air-dissolving rod 8 on the water flow are limited, thereby affecting the overall air-dissolving efficiency of the device; and in the present invention When the micro-bubble dissolving dev...

Embodiment 2

[0039] see Figure 5 As shown, the inside of the flow groove 13 is slidably connected with a blocking ball 23, the inner end of the flow groove 13 is connected with a supporting net 24, and an elastic block 25 is connected between the blocking ball 23 and the supporting net 24. Limiting grooves 26 are symmetrically provided on the side walls of the circulation groove 13, and the limiting grooves 26 are internally connected with a limiting plate 27 of elastic material, and the side walls of the limiting grooves 26 can support the free end of the limiting plate 27 away from The rotation of one side of the net 24 is limited; when the slide plate 11 slides to the inside of the sliding cavity, the limit plate 27 limits the movement of the blocking ball 23 to the outer end of the flow groove 13, making it difficult for the liquid inside the sliding cavity to flow out. When the pressure of the sliding plate 11 on the inside of the sliding cavity reaches a certain value, the liquid in...

Abstract

The invention relates to the technical field of air dissolving devices for sewage treatment, in particular to an efficient microbubble air dissolving device which comprises a tank body, a water inlet pipe and an air inlet pipe are arranged at one end of the tank body, a water outlet pipe is arranged at the end, away from the water inlet pipe, of the tank body, a rotating rod is rotationally connected to the middle of the end face of the tank body, and a plurality of spiral fan blades are fixedly connected to the rotating rod; high-pressure water flow in linear motion in the pipe body can be changed into water flow in high-speed spiral motion, the contact liquid level between gas and the water flow is increased, and the larger the contact liquid level between the gas and the water is, the higher the efficiency of the gas in the water is, namely the shorter the time of the gas in the water is, the larger the quantity of the gas in the water is, the using effect of the dissolving device is improved, meanwhile, the spiral fan blades are driven by high-pressure water flow to continuously rotate, and a power assembly does not need to be additionally arranged for additionally driving the spiral fan blades, so that the device is more energy-saving, and the use cost of the device is reduced.

Description

technical field [0001] The invention relates to the technical field of an air-dissolving device for sewage treatment, in particular to a high-efficiency micro-bubble air-dissolving device. Background technique [0002] The commonly used dissolved air system is a vertical stuffing tank. The air-dissolving method of this technology is to fill the ball packing ring in the tank to chop air and water and increase the contact surface area of ​​air and water. This kind of tank is installed vertically, the residence time is as long as 2-5 minutes, the volume is very large, the filler is easy to block, and the gas-dissolving efficiency is not high. [0003] There are also some technical solutions about micro-bubble dissolving devices in the prior art, such as a Chinese patent, patent number 2013102169664, which proposes a rapid micro-bubble dissolving device, including a recumbent dissolving tank body, the cross-section of the dissolved air tank is circular, a water inlet pipe is c...
