Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated liftable constant-pressure tubular aeration device. Background Art

[0002] With the development of society and the continuous improvement of people's awareness of environmental protection, sewage treatment technology has been more and more widely used. In the sewage treatment process, aeration is a very important link. It can provide sufficient oxygen for microorganisms, promote the growth and metabolism of microorganisms, and thus improve the efficiency of sewage treatment. There are two main traditional aeration methods: air aeration and mechanical aeration. Air aeration is to send air into the aeration tank through a blower to fully mix the air and sewage to achieve the purpose of aeration; mechanical aeration is to bring air into the sewage through a mechanical agitator to achieve the purpose of aeration. However, these traditional aeration methods have some problems, such as uneven aeration, high energy consumption, and difficult maintenance.

[0003] In order to solve these problems, the existing tubular aeration device integrates the aerator, air inlet pipe, water outlet pipe and other components into the aeration tank for sewage treatment. When cleaning is required, the aerator can be lifted out of the aeration tank by a lifting device for cleaning and maintenance.

[0004] However, the applicant has found that the existing tubular aeration device needs to be completely removed from the sewage treatment tank and moved to the ground for cleaning. This process is not only cumbersome and time-consuming, but also requires a cleaning site. Utility Model Content

[0020] In order to make the technical purpose, technical solution and beneficial effects of the present utility model clearer, the technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The utility model provides an integrated liftable constant pressure tubular aeration device, which is used to increase the oxygen content in water during sewage treatment. As shown in the figure, the device includes an aeration system, a lifting mechanism 4, a guiding mechanism and a locking member 8.

[0022] The aeration system includes a distributor 1, a tubular aerator 2, and a maintenance pedal 3. The distributor 1 is a rectangular frame structure. The distributor 1 can provide stable structural support while distributing airflow. There are multiple tubular aerators 2, and multiple tubular aerators 2 are arranged in the frame of the distributor 1 at intervals along the length direction of the distributor 1. The distributor 1 is provided with a maintenance pedal 3. The two ends of the maintenance pedal 3 are respectively fixed to the distributor 1. The pedal allows the staff to stand directly on the aeration device to inspect, clean or repair the aerator. Any tubular aerator 2 is connected to the distributor 1. The tubular aerator 2 is a prior art, and the distributor 1 is also a prior art. This application does not change the distribution of the distributor 1, but only sets its appearance to a rectangular frame structure. For ease of understanding, this application states the rectangular frame distributor 1 as follows:

[0023] The distributor 1 includes a main frame, a gas distribution pipeline, and an interface of the tubular aerator 2. The main frame is a rectangular frame structure and is generally made of metal materials (such as stainless steel or aluminum alloy) to ensure structural stability. The pedal is fixed on the main frame. The gas distribution pipeline is used to evenly distribute compressed air or other gases from the gas supply source to each tubular aerator 2. The gas distribution pipeline is installed in the inner cavity of the main frame. The gas distribution pipeline includes a main distribution pipe and two branch distribution pipes. The main distribution pipe is arranged in the horizontal frame of the main frame. The two branch distribution pipes are respectively arranged in the two vertical frames of the main frame. The two branch distribution pipes are respectively connected to the main distribution pipe. A connecting flange connected to the main distribution pipe for connecting to the external gas supply pipeline is provided on the horizontal frame of the main frame. A plurality of preset holes are spaced apart on the inner wall of the vertical frame of the main frame along the extension direction. The interfaces of the branch distribution pipes correspond to and pass through the preset holes one by one. The two ends of the tubular aerator 2 are connected to the interfaces of the two corresponding branch distribution pipes through quick-release connectors. The quick-release connectors can be set as clamp-type connectors.

[0024] The lifting mechanism 4 is installed on the rectangular frame distributor 1, and the guiding mechanism is arranged at at least two ends of the aeration system. The external lifting device can lift the height of the aeration system through the lifting mechanism 4, and the guiding mechanism guides the aeration system to move vertically. The locking member 8 is detachably connected to the guiding mechanism to unlock or lock the relative position of the guiding mechanism and the aeration system.

[0025] The lifting mechanism 4 includes a lifting ring and four lifting ropes, one end of each of which is connected to the distributor 1, and the other end of each of which is connected to the lifting ring, so that the four lifting ropes and the distributor 1 form a conical stable structure. The lifting hook of the lifting device passes through the lifting ring and then rises and falls to lift and lower the aeration system.

[0026] The guiding mechanism includes a track 5 vertically arranged outside the end of the aeration system, and two positioning posts 7 arranged on the end of the aeration system and located on both sides of the track 5. When the aeration system moves toward the positioning posts 7, the positioning posts 7 can abut against the track 5 to limit the movement distance of the aeration system in the direction of the positioning posts 7. The two positioning posts 7 are located on both sides of the track 5, which can limit the movement of the aeration system in two directions. At the same time, after the aeration system moves in the direction of the track 5, it can abut against the track 5, that is, the track 5 also limits the movement of the aeration system in one direction. Therefore, the guiding mechanism arranged in one direction of the aeration system can limit the movement of the aeration system in three directions.

[0027] In order to limit the shaking of the aeration system after it is lifted, the guiding mechanism is arranged at the opposite ends of the aeration system, and one or at least two spaced guiding mechanisms are respectively arranged at the opposite ends of the aeration system. The guiding mechanism on one end of the aeration system and the guiding mechanism on the other end of the aeration system cooperate to limit the horizontal movement of the aeration system.

[0028] Alternatively, the guiding mechanism is arranged at two adjacent ends of the aeration system, and one or at least two spaced guiding mechanisms are respectively arranged at the two adjacent ends of the aeration system, and the guiding mechanism on one end of the aeration system cooperates with the guiding mechanism on the other end of the aeration system to limit the horizontal movement of the aeration system.

[0029] However, the above can only limit the movement in the horizontal direction. If the height direction is limited only by the external lifting device, if the ring is removed during the maintenance process, it will cause injuries to the workers. To solve this problem, the track 5 is provided with a fixed frame 6 arranged at intervals along its length direction, and the locking member 8 includes a bayonet 81 and a clamp 82 fixed on both sides of the bayonet 81. The bayonet 81 and the clamp 82 of the locking member 8 are respectively arranged by cooperating with the fixed frame 6 and the positioning column 7, so that the locking member 8 locks and unlocks the relative position of the aeration system and the guide mechanism. Specifically, the bayonet 81 is set as a tubular structure with an opening at one end, and the bayonet 81 can be matched and fitted on the fixed frame 6, and the clamp 82 is set as a plate-like structure. The two positioning columns 7 can be placed on the two clamps 82 when the bayonet 81 is fitted on the fixed frame 6, or the bayonet 81 is set as a plate-like structure, and the clamp 82 is set as a tubular structure with an opening at one end. The two clamps 82 can be matched and fitted on the two positioning columns 7 at the same time, and the fixed frame 6 is against the upper side of the bayonet 81.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
