Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to a mobile aeration device, system and control method. Background Art

[0002] Centralized wastewater treatment has essentially resolved the water pollution issues that concern people and has become the primary method for wastewater treatment. The biochemical stage of centralized wastewater treatment, such as the Carrousel oxidation ditch, Orbel oxidation ditch, CASS, SBR, and AAO biochemical treatment processes, primarily utilizes aeration equipment such as disc aerators, rotating disc surface aerators, inverted umbrella aerators, suspended chain aerators, and hose aerators.

[0003] However, traditional aeration pipes are installed at the bottom of the pool and are generally single-layer aeration, resulting in low aeration efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a mobile aeration device to solve the problem of insufficient aeration in a single-layer aeration device.

[0005] In order to solve the above technical problems, the present invention provides a mobile aeration device, including a pipe rack and an aeration nozzle arranged on the pipe rack, the pipe rack includes a main pipe, a clamping rod is provided above the main pipe, a hanging ring is provided above the clamping rod, an air intake pipe is provided on one side above the main pipe, a plurality of layered and detachable first branch pipes are provided around the main pipe below the air intake pipe, and a plurality of detachable second branch pipes are provided on the first branch pipe.

[0006] In a preferred solution, an electric valve is provided between the main pipeline and the first branch pipeline, and both sides of the electric valve are threadedly connected to the first branch pipeline and the main pipeline respectively.

[0007] In a preferred embodiment, a connecting piece is provided between the first branch pipe and the second branch pipe, and a first through hole and a second through hole perpendicular to each other are provided on the connecting piece. The first branch pipe is installed in the first through hole, and the second branch pipe is installed in the second through hole. A third through hole connected to the second through hole is also provided in the first through hole. At least two annular grooves for installing sealing rings are provided in the first through hole and the second through hole, and the third through hole is arranged between the two annular grooves.

[0008] In a preferred embodiment, the connecting member includes a first clamping member, a second clamping member and a third clamping member. The first clamping member is provided with a semicircle, the second clamping member is provided with two semicircles perpendicular to each other, and the third clamping member is provided with a semicircle. The semicircle of the first clamping member and the semicircle of the second clamping member form a second through hole, and the semicircle of the second clamping member and the semicircle of the third clamping member form a first through hole.

[0009] In the preferred solution, multiple float switches are also provided on the main pipeline. The float switches are arranged above the corresponding first branch pipeline. The position of the float switch is higher than the height of the second branch pipeline on the corresponding first branch pipeline. The float switch is used to detect whether the first branch pipeline is still in water, and the controller thereby controls the electric valve on the first branch pipeline to close.

[0010] In a preferred solution, a pressure sensor is further provided on the first branch pipeline at the bottom. The pressure sensor is electrically connected to the controller, and the pressure sensor is used to detect whether the pipe rack is in contact with the underwater bottom.

[0011] An aeration system includes the mobile aeration device according to any one of items 1-6, and also includes a lifting device, the lifting device including a boom and a winch arranged on the boom, the lifting rope extending from the winch is connected to a lifting ring on the main pipeline, and a clamping device for clamping the main pipeline is also provided below the front end of the boom.

[0012] In a preferred embodiment, the clamping device includes a parallel clamping cylinder and a clamping finger arranged on the parallel clamping cylinder. Two V-shaped blocks are provided on the clamping finger in opposite directions. When working, the lifting rope and the clamping rod pass between the two V-shaped blocks.

[0013] In a preferred solution, a proximity sensor is provided on the clamping finger, the proximity sensor is electrically connected to the controller, and the proximity sensor is used to detect whether the clamping rod reaches the clamping position of the V-block.

[0014] A control method for a mobile aeration device includes a pulling-up stage and a lowering stage of the aeration device.

[0015] The pulling up stage includes: the winch winds up the lifting rope, and the aeration device slowly rises. First, the pressure sensor detects that the aeration device leaves the underwater bottom, and then the uppermost float switch detects that the float switch is out of the water surface. The controller controls the corresponding electric valve below the float switch to close, and the aeration nozzle on the first branch pipe on the top layer stops bursting air. Then, the second float switch below the first float switch detects that it is out of the water surface, and controls the electric valve on the first branch pipe below to close. And so on, until the aeration device leaves the water surface, the aeration nozzle on the first branch pipe on the bottom layer stops bursting air, and the aeration device continues to rise. When the proximity sensor detects that the main pipe has reached the clamping position, the winch stops hoisting, and the controller controls the clamping device to clamp the clamping rod. At this time, the lifting device can move quickly.

[0016] The lowering stage includes: the controller controls the clamping device to release the clamping rod, the winch starts to lower the rope, and the aeration device slowly descends. When the bottom float switch detects that the bottom first branch pipe has entered the water surface, the controller controls to open the electric valve on the bottom first branch pipe, and the aeration nozzle on the first branch pipe starts to explode. Then the float switch on the upper layer detects that the corresponding first branch pipe below has entered the water. And so on. After the aeration device enters the water, the explosion device on the first branch pipe on the top layer of the aeration device starts to explode. When the pressure sensor detects that the aeration device has entered the water bottom, the winch stops lowering the aeration device.

[0017] The beneficial effects of the present invention are as follows: since the present invention provides a mobile aeration device, by arranging multiple layers of first branch pipes and second branch pipes on a pipe rack, aeration can be performed at multiple positions within a three-dimensional height space, thereby improving the aeration efficiency of the aeration device; and by arranging a lifting ring on the pipe rack, the lifting ring can be connected to an external device, thereby facilitating the rapid lifting and movement of the pipe rack.

DETAILED DESCRIPTION

[0025] Example 1

[0026] See also Figure 1-5 As shown, an embodiment of the present application provides a technical solution: it includes a pipe rack 11 and an aeration nozzle 101 arranged on the pipe rack 11, the pipe rack 11 includes a main pipe 111, a clamping rod 17 is provided above the main pipe 111, a hanging ring 12 is provided above the clamping rod 17, an air intake pipe 114 is provided on one side above the main pipe 111, and a plurality of layered and detachable first branch pipes 112 are provided around the main pipe 111 below the air intake pipe 114, and a plurality of detachable second branch pipes 113 are provided on the first branch pipe 112.

[0027] Aeration nozzles 101 are mounted on a pipe rack 11, with each rack having one (a portion is omitted in the figure). Main pipes 111 are positioned at the center of gravity of the entire pipe rack 11, ensuring stable lifting. First branch pipes 112 can be arranged in three layers or spaced according to the depth of the liquid level and the spacing between them. This arrangement primarily aims to improve aeration efficiency. Gas is connected to an inlet pipe 114 via a flexible hose, passing through the aeration pipe and aeration nozzles 101 to achieve aeration. When the aeration device needs to be relocated or lifted for maintenance, it can be lifted by connecting the lifting ring 12 with an external lifting device.

[0028] By arranging multiple layers of first branch pipes and second branch pipes on the pipe rack, aeration can be performed at multiple positions within a three-dimensional height space, thereby improving the aeration efficiency of the aeration device.

[0029] In a preferred solution, an electric valve 13 is provided between the main pipeline 111 and the first branch pipeline 112 , and both sides of the electric valve 13 are threadedly connected to the first branch pipeline 112 and the main pipeline 111 respectively.

[0030] The electric valve 13 can open or close the pipeline as needed, so that the aeration nozzle 101 on the corresponding pipeline can work.

[0031] In a preferred embodiment, a connecting piece 14 is provided between the first branch pipe 112 and the second branch pipe 113, and a first through hole 141 and a second through hole 142 perpendicular to each other are provided on the connecting piece 14. The first branch pipe 112 is installed in the first through hole 141, and the second branch pipe 113 is installed in the second through hole 142. A third through hole 143 connecting the second through hole 142 is also provided in the first through hole 141. At least two annular grooves 144 for installing sealing rings are provided in the first through hole 141 and the second through hole 142, and the third through hole 143 is arranged between the two annular grooves 144.

[0032] In this way, the gas on the first branch pipe 112 can enter the second branch pipe 113 through the third through hole 143 , and a sealing ring is provided in the annular groove 144 to make the connection between the first branch pipe 112 and the second branch pipe 113 more airtight.

[0033] In the preferred embodiment, the connecting member 14 includes a first clamping member 145, a second clamping member 146 and a third clamping member 147. The first clamping member 145 is provided with a semicircle, the second clamping member 146 is provided with two semicircles perpendicular to each other, and the third clamping member 147 is provided with a semicircle. The semicircle of the first clamping member 145 and the semicircle of the second clamping member 146 constitute the second through hole 142, and the semicircle of the second clamping member 146 and the semicircle of the third clamping member 147 constitute the first through hole 141.

[0034] The first clamping member 145 , the second clamping member 146 and the third clamping member 147 are detachably connected via threads.

[0035] In the preferred solution, a plurality of float switches 15 are provided on the main pipe 111. The float switches 15 are arranged above the corresponding first branch pipe 112. The position of the float switch 15 is higher than the height of the second branch pipe 113 on the corresponding first branch pipe 112. The float switch 15 is used to detect whether the first branch pipe 112 is still in water, and the controller thereby controls the electric valve 13 on the first branch pipe 112 to close.

[0036] The float switch, a sophisticated liquid level controller, acts as a smart sentinel in the liquid world, precisely regulating the flow of water through a pump. More than just a simple switch, it's an essential component of automated control systems. Its core function is to transmit signals based on buoyancy changes, guiding the start and stop of the pump and enabling intelligent liquid level management. For float switches, consider the ELICO cable-type float switch.

[0037] When the float switch 15 is underwater, due to the pressure of the water, the float switch 15 detects that the bracket below the float switch 15 is still in the water. The float switch 15 and the number of layers of the first branch pipe 112 correspond one to one. One float switch 15 only corresponds to one layer of the first branch pipe 112. When a float switch 15 comes out of the water, the controller can control the closure of the first branch pipe 112 below the float switch 15.

[0038] In a preferred solution, a pressure sensor 16 is further provided on the lowest first branch pipe 112 . The pressure sensor 16 is electrically connected to the controller. The pressure sensor 16 is used to detect whether the pipe rack 11 is in contact with the underwater bottom.

[0039] The pressure sensor 16 is used to detect whether the pipe rack 11 has reached the bottom of the water, because the pipe rack 11 has a certain weight and is greater than the buoyancy of the water, so the pipe rack 11 sinks under the action of gravity.

[0040] Embodiment 2

[0041] Further illustrated in combination with Embodiment 1:

[0042] An aeration system, comprising the mobile aeration device of any one of Embodiments 1-6, further comprising a hoisting device 2, the hoisting device 2 comprising a boom 23 and a winch 21 arranged on the boom 23, a hoisting rope 211 of the winch 21 being connected with the lifting ring 12 on the main pipe 111, and a clamping device 3 for clamping the main pipe 111 being arranged below the front end of the boom 23.

[0043] The hoisting device 2 further comprises a fixed base 24, a rotary arm 22 being arranged above the fixed base 24, the fixed base 24 and the rotary arm 22 being connected through a rotary bearing 25, a gear motor 26 being arranged on the rotary arm 22, and an oil cylinder 27 being arranged between the rotary arm 22 and the boom 23.

[0044] The hoisting device 2 can also be other cranes or the like.

[0045] In the preferred embodiment, the clamping device 3 comprises a parallel jaw cylinder 31 and a clamping finger 32 arranged on the parallel jaw cylinder 31, two V-shaped blocks 33 being arranged on the clamping finger 32 in opposite directions, and the hoisting rope 211 and the clamping rod 17 passing through between the two V-shaped blocks 33 during operation.

[0046] In the preferred embodiment, a proximity sensor 34 is arranged on the clamping finger 32, the proximity sensor 34 being electrically connected with a controller, and the proximity sensor 34 being used to detect whether the clamping rod 17 reaches the clamping position of the V-shaped block 33.

[0047] When the proximity sensor 34 detects the main pipe 111, the controller controls the clamping device 3 to clamp the main pipe 111, and the main purpose at this time is to facilitate the rapid movement of the pipe rack 11. After all, if the pipe rack 11 is directly moved by the hoisting rope 211, the pipe rack 11 will shake too much, which is not conducive to the movement of the pipe rack 11. In this way, the speed of the pipe rack 11 moving horizontally can be improved, the hoisting device 2 can move the pipe rack 11 from one position to another position more conveniently, and the overall efficiency of the aeration can be improved.

[0048] Embodiment 3

[0049] Further illustrated in combination with Embodiments 1 and 2:

[0050] A control method of a mobile aeration device, comprising a pulling-up stage and a lowering stage of the aeration device,

[0051] The pulling up stage includes: the winch 21 winds up the lifting rope 211, and the aeration device slowly rises. First, the pressure sensor 16 detects that the aeration device leaves the underwater bottom, and then the uppermost float switch 15 detects that the float switch 15 leaves the water surface. The controller controls the corresponding electric valve 13 below the float switch 15 to close, and the aeration nozzle 101 on the uppermost first branch pipe 112 stops bursting air. Then, the second float switch 15 below the first float switch 15 detects that it leaves the water surface, and controls the electric valve 13 on the lower first branch pipe 112 to close. And so on, until the aeration device leaves the water surface, the aeration nozzle 101 on the lowermost first branch pipe 112 stops bursting air, and the aeration device continues to rise. When the proximity sensor 34 detects that the main pipe 111 reaches the clamping position, the winch 21 stops winching, and the controller controls the clamping device 3 to clamp the clamping rod 17. At this time, the lifting device 2 can move quickly.

[0052] The lowering stage includes: the controller controls the clamping device 3 to release the clamping rod 17, the winch 21 starts to lower the lifting rope 211, and the aeration device slowly descends. When the bottom float switch 15 detects that the bottom first branch pipe 112 has entered the water surface, the controller controls to open the electric valve 13 on the bottom first branch pipe 112, and the aeration nozzle 101 on the first branch pipe 112 starts to explode. Then the float switch 15 on the upper layer detects that the corresponding first branch pipe 112 below has entered the water. And so on. After the aeration device enters underwater, the explosion device on the top first branch pipe 112 of the aeration device starts to explode. When the pressure sensor 16 detects that the aeration device has entered the bottom of the water, the winch 21 stops lowering the aeration device.

[0053] The main purpose of controlling the aeration device in this way is to improve the efficiency of aeration. If aeration is started only after the aeration device is completely inserted into the pool or lowered to the bottom of the pool, the start time of aeration will be much slower than this method, and the efficiency of aeration cannot be improved.

[0054] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. In other words, equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
