[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to 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.

[0030] Example:

[0031] A sedimentation tank inclined tube air-water mixing cleaning device, such as Figure 1-2 As shown, it includes a riser 1, one end of which is connected to an external fan, and the other end is connected to a main air pipe 2. The main air pipe 2 is connected to a plurality of bronchi 4, and the bronchi 4 is provided with a plurality of air holes 5. The end of the main air pipe 2 away from the riser 1 and the end of the bronchi 4 away from the main air pipe 2 are both blocked by a plug 8.

[0032] In a possible implementation, the riser 1 is fixed to the side wall via a wall bracket, and the upper end thereof is connected to an external fan outlet duct via a flange.

[0033] In a possible implementation, the standpipe 1 is connected to the main gas pipe 2 through an elbow.

[0034] In a possible embodiment, the bronchus 4 is connected to the main trachea 2 via the saddle 7 .

[0035] In a possible implementation, both the main trachea 2 and the bronchial tube 4 are made of ABS pipes.

[0036] In a possible embodiment, a bracket 3 is further included for installing and fixing the main air pipe 2 and the bronchial pipe 4. The bracket 3 is directly fixed on the inclined pipe bracket on site in an upside-down hanging manner.

[0037] In a possible embodiment, the main airway 2 includes several pipe sections, which are respectively connected to several bronchi 4, and each pipe section is provided with an electric / manual valve for control.

[0038] In one possible embodiment, the vertical pipe 1 of the oblique-tube purging device is fixed to the side wall via a wall bracket, and the upper portion is connected to the fan outlet duct using a flange; the main air pipe 1 is connected to the vertical pipe using an elbow at the end, and is connected to the bronchial pipe 4 on the side using a saddle seat 7; the bronchial pipe 4 is provided with evenly distributed air holes 5 to achieve the purging effect. The oblique-tube air-water mixing cleaning device for the sedimentation tank of the present invention can continuously purge without interruption, has low power consumption, and the pipes inside and outside the tank can be connected using flanges, which are detachable, simple to install, and highly efficient and energy-saving. At the same time, the main air pipe 2 is controlled by a multi-section valve, which is convenient for daily operation and maintenance as well as later repair and replacement, and has the advantages of long service life, low maintenance cost, and wider applicability.

[0039] In one possible implementation, an air-water hybrid cleaning device utilizes the combined action of air and water to clean sedimentation tank inclined pipes without the use of any chemical cleaning agents. This technology features ease of operation, unaffected by complex piping, no damage to the pipe network, long operating distances, high efficiency, and strong adaptability. It is suitable for construction in complex pipe networks and can clean a wide range of inclined pipes, ranging from 25 to 100 mm in diameter. It is also suitable for materials such as polypropylene, PVC, fiberglass, and stainless steel. It saves time, effort, and energy, while offering low cleaning costs, a pollution-free design, and excellent cleaning results.

[0040] In one possible implementation, air-water mixed cleaning technology uses a strong impact of air and water to effectively strip and flush away dirt, scale, and biofilm adhering to the inner walls of the auxiliary pipe, restoring the pipe's smooth flow and cleanliness. For common inclined tube sedimentation tanks, installing this pulse flushing device can effectively reduce sludge adhesion, extend the life of the inclined tube, and reduce subsequent maintenance costs.

[0041] In a possible embodiment, the main air pipe 2, bronchial pipe 4, etc. are mostly made of ABS pipes, which have the advantages of corrosion resistance and good hardness, are inexpensive and can meet the use requirements and service life; elbows, flanges, saddle seats, etc. are used as connection methods, which are quick and convenient to install; the bracket 3 is mostly fixed directly on the inclined pipe bracket on site in an inverted hanging manner, which effectively saves the cost and difficulty of installation; the evenly distributed air holes 5 can effectively ensure the uniformity of blowing and better use effect, and the use of natural wind and raw water for cleaning is more environmentally friendly and economical.

[0042] It is worth noting that the above situation is used for bottom blowing of sedimentation tank fillers such as inclined tubes or inclined plates. Its function is to effectively prevent silt from adhering to the inner wall of the filler, increase the service life of the filler and reduce maintenance costs. Under certain conditions, changing the installation height of the device can also play a different role in the internal cleaning of the sedimentation tank. For example, installing it to the bottom of the sedimentation tank can effectively play the role of air stirring, increase the activity of the silt at the bottom of the sedimentation tank, and make it less likely to accumulate.

[0043] In one possible embodiment, during use, the main air pipe 2 can be divided into multiple separately used systems, each of which is equipped with an electric / manual valve for control, thereby achieving segmented control. Not only can the uniformity of hydraulic stirring be adjusted during use, but the cost of installation and maintenance can also be simplified.

[0044] In a possible embodiment, during the use of the project, the aeration fan fills the fan air volume into the riser 1 through the air inlet pipe, and is divided into each branch pipe 4 along the main air pipe, and finally the wind is ejected through the air hole 5. During the production, the aperture (usually 4-8mm), spacing (usually 100-500mm), and number of the air holes 5 need to be carefully calculated in the calculation sheet; the layout spacing of the branch pipes (usually 1000-1500mm), the total aeration air volume of the aeration should be based on the area of ​​the pool (the commonly used stirring load is 0.03-0.1m 3 / min), and then make a comprehensive calculation based on factors such as the aperture of the inclined tube, the quality and quantity of water being treated, etc.

[0045] Generally speaking, the aperture size of the inclined pipe is proportional to the density of the purge pipe, that is, the larger the aperture of the inclined pipe, the larger the required purge pipe layout spacing can be, and under the same conditions, the required total air volume is also smaller; and the selection of the pipe diameter of the main air pipe 2 and the bronchial pipe 4 needs to select the appropriate wind speed according to the pressure-bearing strength of the pipe; the calculated wind speed of the main air pipe 2 and the bronchial pipe 4 for conventional PN10 pipes is 5-8m / s, and the appropriate minimum pipe diameter requirements for the main and branch pipes are selected through calculation. The final selection and confirmation of the pipe diameter also requires comprehensive consideration of the pipe strength. To prevent damage, branches with too small a diameter cannot be selected; the number and spacing of the mounting brackets 3 are calculated based on the hardness, length and weight of the pipe itself, and it is necessary to ensure that the air pipe does not bend or deform during operation, and that there is no strong vibration during system operation.

[0046] Furthermore, the opening size of the air hole 5 is mostly 4-8mm. The number of openings is calculated based on its cross-sectional area and the flow rate through the hole (generally 8-12m / s). It should be noted that the distribution of the air holes must be uniform to ensure that the final flow rate through the hole is greater than the flow rate of the main branch pipe. Only in this way can the intensity of the water flow disturbance be increased and the uniformity of flushing be increased, thereby reducing the occurrence of flushing dead corners and sludge that cannot be flushed away, thereby making the purging process more efficient.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
