Description

Technical Field

[0001] The invention relates to the technical field of biochemical pools, and in particular to a floating type heating aeration and oxygenation device for a biochemical pool. Background Art

[0002] The perforated aeration device is a device that accelerates the transfer of oxygen in water through aeration. Its working principle is: add oxygen to the water, disperse the gas in the water through the aeration device to form bubbles, and the bubbles will drive the suspended particles and microorganisms in the water to rise in the process of rising in the water, so that they can fully contact with oxygen, thereby achieving the purpose of accelerating oxygen transfer. The purpose of setting a heated aeration and oxygenation device in the anoxic pool included in the biochemical pool is: first, to fully stir the water in the anoxic pool so that the denitrifying bacteria can fully contact with organic matter and increase the denitrification rate; second, to provide a small amount of dissolved oxygen for the biological enzymes of the denitrifying bacteria, promote denitrification, and improve the denitrification efficiency; third, when the water temperature is low in winter, hot air is introduced to ensure that the water temperature in the anoxic pool is not lower than 10 degrees Celsius, which is beneficial to the metabolism and reproduction of denitrifying bacteria. The following problems exist in the existing technology:

[0003] Because the existing perforated aeration device is mainly installed at the bottom of the anoxic tank and works in a suspended state at a certain distance from the bottom of the tank, oxygen is output by using aeration heads distributed in a plurality of rectangular arrays. However, due to the fixed nature of the pipeline, when the aeration head needs to be inspected or cleaned, the water in the anoxic tank can only be completely drained to allow the perforated aeration device at the bottom to completely leak out.

The lifting mechanism 23 includes two limiting extension plates 231 on the left and right sides. The two limiting extension plates 231 are respectively fixedly installed on the left and right sides of the top of the rotating mounting plate 22. The two limiting extension plates 231 are both provided with sliding grooves that pass through the upper and lower parts. The top ends of the two lifting racks 36 respectively pass through the sliding grooves provided in the two limiting extension plates 231 to the top thereof. An L-shaped motor bracket 232 is fixedly installed on the left side of the left limiting extension plate 231, and a lifting drive motor 233 is fixedly installed on the vertical top of the L-shaped motor bracket 232. A rotating rod 234 is fixedly installed on the output shaft of the lifting drive motor 233.

[0029] Example 2

[0030] like Figure 1-6As shown, based on Example 1, the present invention provides a technical solution: preferably, the rear end of the horizontal part of the L-shaped air intake pipe 37 is fixedly connected with a telescopic hose 2 371, the rear end of the telescopic hose 2 371 is fixedly connected with a high-pressure oxygen connecting pipe 372, and the rear end of the high-pressure oxygen connecting pipe 372 is externally connected with an oxygen supply device.

[0031] In this embodiment, when supplying oxygen, the oxygen supply equipment is connected through the high-pressure oxygen connecting pipe 372, and then the oxygen passes through the telescopic hose 2 371 and the L-shaped air inlet pipe 37 and then enters the telescopic hose 1 35, and then the oxygen is transported to the square gas supply pipe 31 through the gas supply hard pipe 33 connected to the bottom of the telescopic hose 1 35. After passing through the square gas supply pipe 31 and the three perforated connecting pipes 32, the oxygen can be sprayed out in the form of bubbles through the bubble generator 322 connected to the top of the oxygen outlet fixing ring 321, so as to aerate and oxygenate the liquid in the biochemical anoxic pool 1.

At the same time, when the square gas supply pipe 31 rotates, there is no need to disconnect the high-pressure oxygen connecting pipe 372 from the oxygen supply equipment, and the oxygen supply work can be carried out normally with the help of the telescopic deformation of the telescopic hose 2 371.

[0032] Example 3

[0033] like Figure 1-6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a rotating gear 221 is fixedly installed on the front side of the bottom of the rotating mounting plate 22, a connecting column 222 is fixedly installed on the bottom of the rotating gear 221, the bottom of the connecting column 222 is movably connected to the top of the mounting base plate 21, a servo motor 212 is fixedly installed on the rear side of the top of the mounting base plate 21, a gear 213 is fixedly installed on the output shaft of the servo motor 212, the gear 213 is meshed with the rotating gear 221, the top of the gear 213 overlaps the bottom of the rotating mounting plate 22, mounting plates 211 are fixedly installed on the left and right sides of the mounting base plate 21, and three fixing bolts are respectively provided on the tops of the two mounting plates 211.

[0034] In this embodiment, when the bubble generator 322 on the perforated connecting pipe 32 near the middle needs to be inspected and cleaned but cannot be accessed, the servo motor 212 on the top of the mounting base plate 21 can be started to drive the gear 213 to rotate, and the gear 213 is engaged with the rotating gear 221 at the bottom of the rotating mounting plate 22. The entire rotating mounting plate 22 can be driven to rotate ninety degrees under the relationship of active connection between the connecting column 222 and the top of the mounting base plate 21. The servo motor 212 can use the encoder to accurately control the rotation speed and start and stop, so that it is convenient to stop at a precise position, so that the entire square gas supply pipe 31 is finally rotated and transferred to the top side of the biochemical anoxic pool 1, so that the bubble generator 322 on the perforated connecting pipe 32 in the middle part of the square gas supply pipe 31 can be cleaned or inspected.

[0035] Example 4

[0036] like Figure 1-6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, three perforated connecting tubes 32 and the outer walls on the left and right sides of the square gas supply pipe 31 are respectively and evenly fixedly connected with four oxygen outlet fixing rings 321, and the top of the oxygen outlet fixing ring 321 is provided with a bubble generator 322, the top of the oxygen outlet fixing ring 321 is fixedly connected with an internally threaded air outlet pipe 3211 passing through its inner cavity, the bottom of the bubble generator 322 is fixedly connected with a threaded connecting pipe 3221 passing through its inner cavity, a sealing rubber ring 3222 is sleeved on the outer wall of the threaded connecting pipe 3221, and the threaded connecting pipe 3221 is threadedly connected to the inner ring of the internally threaded air outlet pipe 3211.

[0037] In this embodiment, when the bubble generator 322 needs to be thoroughly cleaned or disassembled for maintenance, the bubble generator 322 only needs to be rotated, so that the oxygen outlet fixing ring 321 at the bottom of the bubble generator 322 and the inner circle thread of the internally threaded air outlet pipe 3211 at the top of the oxygen outlet fixing ring 321 are rotated and separated, so that they can be directly fallen off for easy cleaning. During installation, it is only necessary to align the threaded connecting pipe 3221 with the inner circle of the internally threaded air outlet pipe 3211 and rotate and tighten it until it is tight against the sealing rubber ring 3222 to complete the sealed and fixed connection without affecting continued use.

[0038] The following is a detailed description of the working principle of the floating heated aeration and oxygenation device used in the biochemical pool.

[0039] like Figure 1-6As shown, when delivering oxygen, the oxygen delivery device is connected through the high-pressure oxygen connecting pipe 372, and then the oxygen passes through the telescopic hose 2 371 and the L-shaped air inlet pipe 37 and then enters the telescopic hose 1 35, and then the oxygen is delivered to the square air delivery pipe 31 through the air delivery hard pipe 33 connected to the bottom of the telescopic hose 1 35. After passing through the square air delivery pipe 31 and the three perforated connecting pipes 32, the oxygen can be sprayed out in the form of bubbles through the bubble generator 322 connected to the top of the oxygen outlet fixing ring 321, and the liquid in the biochemical anoxic pool 1 is aerated and oxygenated. When heating is required, the oxygen in the oxygen delivery device can be heated in advance. When the square air delivery pipe 31 and the bubble generator 322 need to be repaired or cleaned, there is no need to clean the biochemical anoxic pool 1. To discharge the liquid in the left limit extension plate 231, it is only necessary to start the lifting drive motor 233 on the top of the L-shaped motor bracket 232 on the left side of the left limit extension plate 231 to drive the rotating rod 234 to rotate, thereby synchronously driving the two lifting gears 235 to rotate, and the lifting gear 235 is engaged with the rear side of the two lifting racks 36 to drive the two lifting racks 36 to rise in the limited position in the slide groove provided in the limit extension plate 231, so as to cooperate with the fixed connection between the fixed side plate 34 at the bottom of the lifting rack 36 and the gas delivery hard pipe 33, so as to drive the whole square gas delivery pipe 31 to rise, and when rising, it can be stably risen with the help of the retractable soft retractable hose 35, without removing the pipe, until the square gas delivery pipe 31 rises above the biochemical anoxic pool 1, and the square gas delivery pipe 31 can be retracted. The bubble generator 322 on the gas pipe 31 is inspected and cleaned. When the bubble generator 322 on the perforated connecting pipe 32 near the middle needs to be inspected and cleaned but cannot be accessed, the servo motor 212 on the top of the mounting base plate 21 can be started to drive the gear 213 to rotate, and the gear 213 is engaged with the rotating gear 221 at the bottom of the rotating mounting plate 22. The entire rotating mounting plate 22 can be driven to rotate ninety degrees under the relationship of the active connection between the connecting column 222 and the top of the mounting base plate 21. The servo motor 212 can accurately control the rotation speed and start and stop with the help of an encoder, so that it is convenient to stop at a precise position, so that the entire square gas pipe 31 is finally rotated and transferred to the top side of the biochemical anoxic pool 1, and at the same time When the square air supply pipe 31 rotates, there is no need to disconnect the high-pressure oxygen connecting pipe 372 from the oxygen supply equipment. The oxygen supply work can be carried out normally with the help of the telescopic deformation of the telescopic hose 371. When the bubble generator 322 needs to be thoroughly cleaned or disassembled for maintenance, it is only necessary to rotate the bubble generator 322, so that the oxygen outlet fixing ring 321 at the bottom of the bubble generator 322 and the inner circle thread of the internal threaded air outlet pipe 3211 at the top of the oxygen outlet fixing ring 321 are rotated and separated, so that they can be directly fallen off for easy cleaning. During installation, it is only necessary to align the threaded connecting pipe 3221 with the inner circle of the internal threaded air outlet pipe 3211 and rotate and tighten it until it is tight against the sealing rubber ring 3222 to complete the sealed fixed connection without affecting continued use.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
