A raft-type liftable aerator

Abstract

This utility model discloses a raft-type liftable aerator, relating to the field of aerator technology. The utility model includes plastic floats, elbows, tees, connectors, aeration risers, an aerator body, and steel wire ropes. Two floats are provided, and several elbows are provided, with the two floats connected by the elbows. By using two floats connected by several elbows and then joined by the connector to form a raft, the stability of the aerator body is increased. Four steel wire ropes are used to fix the entire raft, adding two more steel wire ropes than the single float of the original suspended chain aeration system, further reducing the swaying amplitude of the floats on the water surface. By replacing the hose (snake-skin hose) connection between the floats and the aerator body with a connector that connects to the aerator body via the aeration riser (which is a rigid pipe), tangling of the hose (snake-skin hose) is avoided, preventing tangling from affecting the equipment's performance and maintenance.

Technical Field

[0001] This utility model relates to the field of aerator technology, specifically a raft-type liftable aerator. Background Technology

[0002] The liftable suspended chain aerator is an energy-saving aeration device, mainly used for oxygenation of activated sludge in the treatment of industrial wastewater such as petrochemical, textile and papermaking industries and urban domestic sewage. The device adopts a modular design and consists of an air supply hose, a floating air distribution pipe, a suspended air delivery hose and a rubber membrane tube aeration unit.

[0003] However, existing liftable suspended chain aerators still have some drawbacks:

[0004] In existing technologies, liftable suspended chain aerators often suffer from problems due to the tangled hoses (snake-skin tubes) of two or more aerators, which affects the equipment's performance, makes maintenance difficult and expensive, and makes the aerators prone to swinging and colliding in the water during use, causing damage to the equipment. In addition, the hoses (snake-skin tubes) are often fixed with stainless steel clamps, which make them prone to falling off during use, thus affecting the equipment's performance and requiring a large amount of maintenance.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: As Figure 1-3 As shown, this utility model provides a raft-type liftable aerator. The raft-type liftable aerator includes a float pipe 1, plastic elbows 2, plastic tees 3, connectors 4, an aeration riser 5, an aerator body 6, a counterweight 7, and a steel wire rope 8. The aeration riser 5 is a metal pipe. Two float pipes 1 and four plastic elbows 2 are provided. By setting two float pipes 1 and four plastic elbows 2, together with multiple connectors 4, a raft body is formed, increasing the stability of the aerator body 6. The two float pipes 1 are connected by four plastic elbows 2. The plastic tees 3 are set between two of the plastic elbows 2 and are connected to the float pipes 1 through plastic elbows 2. One end of the plastic tees 3 is provided with an air supply hose 31. Several connectors 4, aeration risers 5, and aerator bodies 6 are provided. The connectors 4 are fixedly set on two float pipes 1 and are connected to the float pipes 1. The aeration riser 5 is set below the connectors 4. An aeration chamber 61 is provided in the middle of the main body 6. The aeration chamber 61 is a square metal air chamber. One end of the aeration riser 5 is fixed to the aeration chamber 61.

The counterweight 7 is fixedly set at the end of the aeration riser 5 near the aerator body 6 and is located at the lower part of the aerator body 6. By setting the counterweight 7, the drift amplitude of the float pipe 1 and the aerator body 6 can be reduced, thereby improving the stability of the float pipe 1 and the aerator body 6. Four steel wire ropes 8 are provided. The steel wire ropes 8 are detachably installed on the float pipe 1. Both ends of the float pipe 1 are provided with clamps 81. One end of the steel wire rope 8 is fixed to the clamp 81, and the other end is fixed to the bracket on the edge of the pool by connecting the spiral lock (adjustable). By setting four steel wire ropes 8 and adjusting the four steel wire ropes 8 by the spiral lock, the drift amplitude of the float pipe 1 on the water surface is reduced.

[0034] The connector 4 is U-shaped and includes a metal horizontal pipe 41, a metal tee 42, a metal elbow 43, a metal union 44, and a metal double-wire short pipe 45. The metal tee 42 is fixedly installed in the middle of the metal horizontal pipe 41, and the aeration riser 5 is connected to the metal horizontal pipe 41 through the metal tee 42. The metal elbow 43 is fixedly installed at one end of the metal horizontal pipe 41, and the metal union 44 is fixedly installed at one end of the metal elbow 43. One end of the metal double-wire short pipe 45 is threaded and detachably installed on the float pipe 1 and connected to the float pipe 1. The other end of the metal double-wire short pipe 45 is threaded and detachably installed at one end of the metal union 44. Compared with the existing technology that uses hoses for connection, the connector 4, composed of the metal horizontal pipe 41, metal tee 42, metal elbow 43, metal union 44, and metal double-wire short pipe 45, avoids tangling and collision between multiple aerator bodies 6, and facilitates installation and disassembly, improving the convenience of maintenance operations.

[0035] Example 2: Figure 4 As shown, unlike Embodiment 1, the connector 4 is arched.

[0036] Example 3: Figure 5 As shown, unlike Embodiment 1, the connector 4 includes a metal horizontal pipe 41, a quick connector 47, and a clamp connector 48. The metal horizontal pipe 41 is an integrally formed metal pipe. The aeration riser 5 is fixed to the middle of the metal horizontal pipe 41 through the quick connector 47. The metal horizontal pipe 41 can be detachably installed on the float pipe 1 through the clamp connector 48.

[0037] Example 4: Figure 6 As shown, unlike Embodiment 1, the aeration riser 5 is a metal-lined plastic pipe, the aeration chamber 61 is a circular plastic air chamber, and several reinforcing ribs 51 are fixedly provided between the aeration riser 5 and the aerator body 6.

[0038] Example 5: Figure 7 As shown, unlike Embodiment 1, two plastic elbows 2 and two air supply hoses 31 are provided. The two plastic elbows 2 are fixedly installed between the two floats 1, and the air supply hoses 31 are fixedly installed at one end of the floats 1.

[0039] Example 6: Figure 8 As shown, unlike Embodiment 5, four gas delivery hoses 31 are provided, and the gas delivery hoses 31 are fixedly installed at one end of the float pipe 1.

[0040] Example 7, as Figure 9 As shown, unlike Embodiment 1, the counterweight 7 is fixedly installed at one end of the aeration riser 5 near the aerator body 6, and the counterweight 7 is located at the upper part of the aerator body 6.

[0041] Example 8, as Figure 10As shown, unlike Embodiment 1, the aerator body 6 is externally fitted with a support tube, and the counterweight 7 is fixedly installed inside the support tube.

[0042] Working principle: By setting two floating pipes 1, which are connected by four plastic elbows 2 to form a raft, the stability of the aerator body 6 is increased.

[0043] The entire raft is secured by four steel wire ropes 8, which is two more steel wire ropes 8 than the single floating pipe 1 of the original suspended chain aeration system, further reducing the swaying amplitude of the floating pipe 1 on the water surface.

[0044] By replacing the hose (snake-skin hose) connecting the float pipe 1 and the aerator body 6 with the connector 4, the tangling between the hoses (snake-skin hose) is avoided, thus preventing the equipment from being affected by the tangling and thus avoiding the impact on the equipment's performance and maintenance.

[0045] The raft body on the water surface is stable and the aerator body 6 is connected by the aeration riser 5, which avoids collision between the aerator bodies 6.

[0046] The original stainless steel hose (snake-skin hose) fixed by the suspension chain aeration system was replaced with connector 4, and a metal union 44 was set in connector 4 for installation and disassembly. This avoids the drawback of hose falling off, and makes it convenient to disassemble and install when the aerator body 6 needs to be replaced after long-term use, saving disassembly and installation time and costs.

[0047] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the pipeline connection adopts conventional connection methods in the prior art, which will not be described in detail here.
