Description

Technical Field

[0001] The present application relates to the technical field of aerators, and in particular to a double-nozzle cyclone aerator. Background Art

[0002] In the process of sewage treatment and aquatic organism breeding, aeration is a key process step. It increases the content of dissolved oxygen in the water by forcibly injecting air into the water to meet the needs of microbial metabolism or the survival of aquatic plants and animals.

[0003] Existing hanging aeration equipment usually includes a cutter, a base and an eccentrically mounted inlet riser. However, due to the eccentric mounting of the inlet riser, the center of gravity of the aerator changes significantly, causing the aerator to easily deform from a vertical state to an inclined state during the aeration process, resulting in unsatisfactory stability and aeration volume of the aerator during use. Utility Model Content

[0004] The problem to be solved by the present application is that the existing hanging type aerator is prone to positional deviation due to the offset of the center of gravity during use, resulting in unsatisfactory stability and aeration volume of the aerator.

[0005] In order to solve the above technical problems, the present application provides a double-nozzle cyclone aerator, including a bracket for serving as a basic support, a vertically arranged riser is arranged at the center position of the upper height direction of the bracket to avoid the center of gravity shift and is used to spray mixing air, and a plurality of cutters are coaxially arranged on the outside of the riser and are connected to the bracket to cut the water body to generate fine bubbles and dissolve oxygen; two branch pipes extending outward and connected are symmetrically arranged in the circumferential direction at the lower end of the riser, and an inclined and symmetrically arranged partition is provided on the outside of the riser.

[0006] Since the aerator of the present application is designed with a bracket, a riser and a cutter, the center of gravity of the aerator can be stabilized by the bracket and the riser, and the aeration volume of the aerator can be increased by the partition and the cutter, thereby solving the problem in the prior art that the existing hanging aerator is prone to position displacement due to the offset center of gravity during use, resulting in unsatisfactory stability and aeration volume of the aerator.

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0016] The present application relates to a double nozzle type cyclone aerator, such as Figure 1-7 As shown, the aerator includes a bracket 3 for serving as a basic support, a vertically arranged riser 10 for spraying mixing air is arranged at the center position of the upper height direction of the bracket 3 to avoid center of gravity shift, and a plurality of cutters 2 are coaxially arranged on the outside of the riser 10 and are connected to the bracket 3 for cutting the water body to generate fine bubbles and dissolve oxygen.

[0017] The cutter 2 includes a barrel 8, a mushroom head 7, and a clamping plate 9. The barrel 8 is a straight hollow structure. A plurality of mushroom heads 7 for cutting gas to improve mixing efficiency are evenly arranged in the circumferential direction inside the barrel 8, and clamping plates 9 for clamping with the side walls of the bracket 3 are symmetrically arranged on the outside of the barrel 8. In order to further improve the cutting effect of the mushroom head 7, the mushroom head 7 is mushroom-shaped, and the mushroom head 7 and the barrel 8 are integrally cast, so that convenient replacement operations can be performed.

[0018] The bracket 3 includes side plates 5 and a pressure plate 4. The side plates 5 adapted to the clamping plates 9 for clamping and fixing are symmetrically arranged on both sides of the vertical pipe 10, and a pressure plate 4 connected to the vertical pipe 10 by a detachable bolt 6 is arranged on the top of the side plate 5 for crimping and fixing the cylinder 8. The center position of the pressure plate 4 is also sleeved with the vertical pipe 10, so as to play an axial auxiliary supporting role therefor. The bracket 3 is made of stainless steel with high strength and corrosion resistance.

[0019] The riser 10 is a tubular structure with a hollow interior, and the side wall at the bottom end is welded to the side plate 5. A sleeve 1 is arranged at the upper end of the riser 10 to fit the hollow structure, so that it is convenient to suspend and fix the riser 10 with the help of the sleeve 1 and the lifting rod in the site. The lower end of the riser 10 is closed.

[0020] In order to increase the aeration amount, two outwardly extending and connected branch pipes 13 are symmetrically arranged in the circumferential direction of the lower end of the vertical pipe 10, and a nozzle 12 is added on the upper part of the branch pipe 13. The nozzle 12 is arranged side by side with the vertical pipe 10 upward, and the length ratio between the branch pipe 13 and the nozzle 12 is 2-2.5:1, and the diameter ratio between the branch pipe 13 and the nozzle 12 is 1-2:1, so that the gas sprayed by the nozzle 12 can be mixed with the water body in a vertically ascending manner. The cross-sectional shape of the branch pipe and the nozzle can be rectangular or circular. At the same time, an inclined and symmetrically arranged baffle 11 can be added to the outer side of the vertical pipe 10, so as to further enhance the turbulence effect of the gas and the water body, so that the two are fully mixed. The inclination angle of the baffle 11 is 15-60°.

[0021] When in use, the aerator is placed in the water body by hoisting, and the riser 10 is connected to the hoisting rod with hoisting ability through the sleeve 1 at its upper end, and then the gas is inflated along the hoisting rod into the riser 10, and then the gas is evenly dispersed circumferentially through the branch pipe 13 at the bottom of the riser 10, and then ejected through the nozzle 12 vertically arranged on the upper part of the branch pipe 13. The ejected gas and the water body are preliminarily rotated and mixed through the partition 11, so that a large number of bubbles are filled in the water body inside the cylinder 8, thereby driving the water body to circulate from bottom to top. The gas bursts through the collision between the gas and the water and the mushroom head 7, thereby increasing the contact area with the water, so that the gas can fully contact the water, which can not only promote the oxidation and decomposition of organic matter in the water, but also increase the dissolved oxygen content in the water, which is beneficial to the subsequent growth and reproduction of microorganisms. The centrally hoisted riser 10 makes the center of gravity of the aerator more stable during operation without position displacement, and thanks to the arrangement of the branch pipe 13 and the nozzle 12, the aeration volume is effectively improved.
