Description

Technical Field

[0001] The utility model belongs to the field of aeration oxygenators, in particular to a negative pressure self-priming spiral push flow oxygenator. Background Art

[0002] Aeration system inspection and maintenance have always been the difficulty and pain point of sewage treatment plant operation. The advent of negative pressure self-priming spiral push flow aerator has largely solved this difficulty and pain point. Its principle is: ① It realizes self-inhalation of air aeration, getting rid of equipment and facilities such as fans, pipes and aeration plates; ② It can impact, break up and mix the accumulated sludge in the aeration tank caused by damage to the aeration system or other factors, so as to make full use of the tank volume; ③ It can greatly reduce the labor, material costs and potential risks of inspection and replacement of aeration heads and pipelines, and long-term application can save a lot of expenses in application costs and maintenance costs.

[0003] The working principle of the negative pressure self-priming spiral push flow oxygenator is that the equipment is installed at a suitable position through a bracket at a 45° angle. The drive motor works, driving the propeller blades to rotate at high speed. The high-speed rotation of the propeller generates negative pressure. Under the action of negative pressure, the air is sucked in through the air inlet and sheared to form microbubbles and diffuse to achieve the aeration function. Generally, the bracket is installed above the aeration tank. In an environment where it is impossible to set up a mounting bracket, upgrading the old factory is a problem that needs to be solved in a timely manner. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a negative pressure self-priming spiral push flow oxygenator to solve the problems raised in the above background technology.

[0006] The buoy unit includes two buoys, which are connected by a transverse support plate and a transverse support rod, and the transverse support plate is fixed below the fixing plate;

[0007] The motor is connected to the main shaft through a shaft sleeve. The main shaft is arranged in a main shaft protective sleeve. A balance bearing is arranged at one end of the main shaft protective sleeve. The main shaft passes through the balance bearing to the outside of the main shaft protective sleeve. A stirring blade is arranged on the surface of the main shaft.

[0008] As a preferred embodiment, a negative pressure air inlet for inhaling external air is opened through the surface of the spindle protection sleeve.

[0011] As a preferred embodiment, the transverse support rod is connected to the two limiting holes through two rolling bearings, and the first buoy and the second buoy can rotate around the two sides of the transverse support rod through the two rolling bearings.

[0012] As a preferred embodiment, the bottom surface of the fixing plate is penetrated with a connecting hole, and the surface of the transverse support plate is penetrated with a through hole corresponding to the connecting hole, and a plurality of connecting holes and through holes are provided.

[0025] 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 of 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.

[0026] See also Figure 1 to Figure 2 , the utility model provides a technical solution:

[0027] A negative pressure self-priming spiral push flow oxygenator, comprising: a buoy 100 unit 100 and a motor 700 movably arranged on the buoy 100 unit 100, two fixing plates 710 symmetrically welded to the bottom of the motor 700, and the two fixing plates 710 are respectively fixed above two buoy 100 units 100;

[0028] The buoy 100 unit 100 includes two buoys 100, and the two buoys 100 are connected by a transverse support plate 130 and a transverse support rod 140, and the transverse support plate 130 is fixed below the fixing plate 710;

[0029] The motor 700 is connected to the main shaft 300 through the shaft sleeve 200. The main shaft 300 is arranged in the main shaft protection sleeve 400. A balance bearing 500 is arranged at one end of the main shaft protection sleeve 400. The main shaft 300 passes through the balance bearing 500 to the outside of the main shaft protection sleeve 400. A stirring blade 600 is arranged on the surface of the main shaft 300.

[0030] This type of negative pressure self-priming spiral push flow oxygenator has the following effects:

[0031] Energy saving: The motor 700 is directly driven to reduce power loss; according to the changes in the treated water load, the number of running units is controlled to achieve energy saving effects.

[0032] Long service life, easy inspection and maintenance: driven on water, no vulnerable parts underwater, long service life; the only consumable part of the entire mechanical part is the balance bearing 500, and no mechanical adjustment is required, which reduces a lot of maintenance work.

[0033] No noise and splashing: The operating sound 1m away from the noise source (motor 700) is less than 72 decibels; no sewage splashing will occur when aerating and stirring in the water, so there is no need for additional noise or splash prevention equipment.

[0034] Efficient oxygenation, flow pushing and homogenization effects: Since the air is broken into tiny bubbles by the high-speed rotating spiral and quickly mixed with the water, efficient oxygenation effect can be achieved. At the same time, due to the effect of the propeller, the equipment has a good mixing and flow pushing effect while oxygenating the water, which has a good effect on water homogenization.

[0035] As an embodiment of the utility model: a negative pressure air inlet for sucking in external air is opened through the surface of the spindle protection sleeve 400.

[0036] The two fixing plates 710 are welded to the two sides of the bottom of the motor 700 through two connecting rods. The two fixing plates 710 are arranged at 45 degrees to the motor 700. This arrangement allows the negative pressure air inlet to better inhale air.

[0037] As an embodiment of the utility model: the two buoys 100 are respectively a first buoy 100 and a second buoy 100, and limiting holes are opened on the inner surfaces of the first buoy 100 and the second buoy 100, and both sides of the transverse support rod 140 pass through the transverse support plate 130 and are inserted into the two limiting holes.

[0038] The transverse support rod 140 is connected to the two limit holes through two rolling bearings. Through the two rolling bearings, the first buoy 100 and the second buoy 100 can rotate around the two sides of the transverse support rod 140. The reason for arranging two rolling bearings is that the second buoy 100 and the first buoy 100 may rotate with the movement of the water surface during actual use. If no rolling bearings are provided, the rolling of the first buoy 100 and the second buoy 100 will drive the transverse support rod 140 and the transverse support plate 130 to rotate, and then drive the fixed plate 710 to rotate, thereby causing the whole to tip over.

[0039] A connecting hole is penetrated through the bottom surface of the fixing plate 710, and a through hole corresponding to the connecting hole is penetrated through the surface of the transverse support plate 130. There are a plurality of connecting holes and through holes. The fixing bolts penetrate the connecting holes and through holes to flexibly connect the fixing plate 710 and the transverse support plate 130 together. This flexible connection method is, firstly, to facilitate the replacement of damaged buoy 100 units 100, and secondly, to facilitate the overall transportation, so that the buoy 100 unit 100 and the motor 700, the main shaft 300, etc. can be disassembled for transportation, and thirdly, it can adapt to different installation environments. If the negative pressure self-priming spiral push flow oxygenator is not suitable for floating on the water surface and needs to be installed on the side of the pool, the buoy 100 unit 100 can be omitted and the fixing plate 710 can be directly fixed to the side of the pool by expansion bolts.

[0040] Limiting ropes are arranged on both sides of the motor 700. By arranging the limiting ropes and winding the two limiting ropes around the appropriate positions of the pool side, the motor 700 can be relatively fixed in an appropriate position to prevent the negative pressure self-priming spiral push flow oxygenator from moving during operation.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
