Description

Technical Field

[0001] The invention relates to aeration equipment, in particular to an oscillating aerator. Background Art

[0002] Aerators are widely used in the industrial field, especially in the process of sewage treatment using biological treatment. They use the principle of aeration diffusion to transfer oxygen in the gas phase to the liquid phase, that is, to transfer oxygen in the gas phase to dissolved oxygen in the liquid phase, which is beneficial to the oxidation and decomposition of impurities in sewage. In order to increase the dissolved oxygen in the liquid phase, the dispersion of the gas phase in the liquid phase is particularly important. Summary of the invention

[0003] The object of the present invention is to provide an oscillating aerator to solve the problem of poor dispersion of gas phase in liquid phase.

[0016] Figure 1 It is a structural schematic diagram of the oscillating aerator of the present invention. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] An oscillating aerator, such as Figure 1 As shown, it includes a first feeding barrel 1, a feeding cover 2 covered on the first feeding barrel 1, a second feeding pipe 3 connected to the feeding cover 2 and a mixing barrel 4 connected to the feeding cover 2, the first feeding barrel 1 and the mixing barrel 4 are coaxially arranged, an oscillation component 5 is arranged in the mixing barrel 4, a push-pull rod 6 is fixed on the oscillation component 5, and the end of the push-pull rod 6 away from the oscillation component 5 passes through the mixing barrel 4 and is connected to a reciprocating telescopic motor 7 fixed outside the mixing barrel 4.

[0019] The oscillating aerator has the discharge end of the first feed barrel 1 close to the feed end of the mixing barrel 4. When the device is in operation, the liquid enters the mixing barrel 4 from the first feed barrel 1. During the liquid flow, a negative pressure is formed at the outlet end of the first feed barrel 1, and the gas is sucked into the feed cover 2 from the second feed pipe 3, and then enters the mixing barrel 4, where the gas and liquid are mixed.

[0020] In order to improve the dispersion effect of gas in liquid, an oscillating component 5 is further provided in the mixing barrel 4. The oscillating component 5 is driven to reciprocate in the mixing barrel 4 by the reciprocating telescopic motor 7, which can further improve the mixing effect of gas and liquid.

[0021] It should be noted that, in theory, the first feed barrel 1 and the second feed barrel in the present application can both feed gas or both feed liquid, and those skilled in the art can make the selection as needed during application.

[0022] In this embodiment, the first feeding barrel 1 is conical, and the cross-section of the first feeding barrel 1 gradually decreases along the feeding direction.

[0023] The cross-section of the first feed barrel 1 gradually decreases along the feeding direction. Under the premise of a constant flow rate, the liquid flow rate will continue to accelerate. When the liquid leaves the first feed barrel 1, the liquid flow rate will be relatively fast, causing the second feed pipe 3 to be subjected to a relatively large negative pressure.

[0024] In this embodiment, the oscillating component 5 includes a spoiler 51 connected to the push-pull rod 6, and an angle is set between the spoiler 51 and the push-pull rod 6.

[0025] During the reciprocating movement, the spoiler 51 disturbs the gas and liquid in the mixing barrel 4, so that the gas and liquid are mixed more fully.

[0026] The spoiler 51 in this embodiment can be in the shape of a plate, a sheet, a strip, a tube, or a rod, and the specific shape can be selected by those skilled in the art as needed. Theoretically, the mixing effect is relatively good when it is in the shape of a sheet or a plate, but the cross-sectional area of ​​the mixing barrel 4 occupied by it is relatively large compared to the tube and rod shapes, which may hinder the flow of the liquid in the mixing barrel 4 and increase the energy consumption of the instant liquid flow, so those skilled in the art need to comprehensively consider the mixing effect and energy consumption to select the shape of the spoiler 51.

[0027] In this embodiment, a connecting rod 52 may be provided on the push-pull rod 6 , and more than two spoilers 51 may be provided on the connecting rod 52 , wherein an angle is provided between at least two spoilers 51 .

[0028] A plurality of spoilers 51 are provided, and the plurality of spoilers 51 are connected by connecting rods 52 , so that one reciprocating telescopic motor 7 can drive the plurality of spoilers 51 , and the structure is relatively simple.

[0029] The multiple spoilers 51 may be arranged in different directions, so that when the spoilers 51 are pushed, each spoiler 51 pushes the liquid in a different direction, resulting in a better mixing effect.

[0030] In this embodiment, the spoiler 51 is a spiral blade.

[0031] The spoiler 51 is a spiral blade. When the spiral blade moves back and forth, the direction of its thrust on the liquid changes constantly, so that the gas and liquid are pushed in different directions. The liquids pushed by two adjacent spoilers 51 collide and mix with each other, so that the original large bubbles are gradually dispersed into small bubbles. Although some small bubbles are combined with each other, the overall dispersion effect is better than that of spoilers 51 in plate or tubular shape.

[0032] In this embodiment, one end of the spoiler 51 away from the push-pull rod 6 is wrapped with an elastic anti-collision head.

[0033] When the reciprocating telescopic motor 7 fails, the reciprocating distance of the spoiler 51 may change, which may cause it to collide with the wall of the mixing tube. In order to avoid a rigid collision between the two and damage to the tube wall or the spoiler 51, an elastic anti-collision head is provided.

[0034] In this embodiment, a leakproof cover 8 is provided at the contact point between the mixing barrel 4 and the push-pull rod 6. The leakproof cover 8 is connected to the feed cover 2 through a connecting pipe 9. A valve is provided on the connecting pipe 9. The second feed pipe 3 is provided with a regulating valve capable of adjusting the feed flow rate of the second feed pipe 3.

[0035] To avoid leakage, a sealing device is provided between the mixing barrel 4 and the push-pull rod 6. The specific sealing structure can be selected by technical personnel in this field as needed. Although the sealing structure in the prior art has a good sealing effect, leakage may occur during long-term use. Therefore, the present application is provided with a leak-proof cover 8, and a sealing structure is also provided between the leak-proof cover 8 and the push-pull rod 6, which is equivalent to a two-stage seal.

[0036] On the other hand, the leakproof cover 8 is connected to the feed cover 2 through the connecting pipe 9. Since there is a certain negative pressure in the feed cover 2, the liquid leaking into the leakproof cover 8 can be pumped into the feed cover 2 and then returned to the mixing barrel 4, thereby avoiding the impact of the leakage on the production environment and avoiding the waste of materials.

[0037] In this embodiment, a liquid collecting groove 81 is arranged in the leakproof cover 8 around the contact point between the mixing barrel 4 and the push-pull rod 6 , and the liquid inlet end of the connecting pipe 9 is located at the bottom of the liquid collecting groove 81 .

[0038] The purpose of the liquid collecting groove 81 is to collect the liquid leaking into the anti-leakage groove in the liquid collecting groove 81 . Even if there is relatively little liquid in the anti-leakage groove, it can enter the feed cover 2 through the connecting pipe 9 .

[0039] Although the present invention is described herein with reference to a number of illustrative embodiments of the present invention, it will be appreciated that those skilled in the art may devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of the present disclosure, drawings, and claims, a variety of variations and modifications may be made to the components and / or layout of the subject combination layout. In addition to the variations and modifications made to the components and / or layout, other uses will also be apparent to those skilled in the art.
