Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of water treatment equipment, in particular to an ultrasonic automatic cleaning device for an aerated grit chamber. Background Art

[0002] Aerated grit chamber is a common equipment in water treatment system. The purpose of using aeration tank is to effectively remove pollutants in the primary stage of sewage treatment, reduce the burden of subsequent treatment process, and provide better conditions for the entire sewage treatment process. Aerated grit chamber removes suspended matter and promotes sedimentation through aeration of aeration pipes. The aeration pipes in aerated grit chamber often get clogged during operation, which is usually caused by excessive accumulation of sand, organic matter or other impurities. There are several aeration holes on the aeration pipes. If the aeration holes are clogged, if they are not cleaned in time, it will affect their working efficiency, so they need to be cleaned in time. At present, most cleaning methods are to shut down the machine first, and then use manual tools or mechanical devices (such as sand suction pumps) for cleaning. This is not only inefficient, but may also affect the operation of the entire water treatment system due to shutdown. If the aeration hole blockage is not discovered and handled in time, it may bring the following disadvantages: 1. Affecting sewage treatment efficiency: Blockage will reduce the aeration volume, resulting in a decrease in the dissolved oxygen content in the water, affecting the activity of microorganisms and sewage treatment efficiency. 2. Increased energy consumption: In order to maintain the same aeration effect, it may be necessary to increase the operating frequency or power of the fan, thereby increasing energy consumption. 3. Risk of equipment damage: Long-term blockage may cause equipment overload, increasing the risk of equipment damage. 4. Increased maintenance costs: Long-term untreated blockage may require replacement of blocked parts, increasing maintenance costs. Utility Model Content

[0003] The utility model aims to address the deficiencies in the prior art and to provide an ultrasonic automatic cleaning device for an aerated grit chamber, which can promptly detect blockages in aeration holes on an aeration pipe and automatically clean the aeration holes without stopping the machine.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] An ultrasonic automatic cleaning device for an aerated grit chamber includes a plurality of ultrasonic vibrators and detection sensors arranged on an aeration pipe, an ultrasonic generator and a control module; the ultrasonic vibrator is connected to the ultrasonic generator, the detection sensor and the ultrasonic generator are electrically connected to the control module, and the detection sensor is used to detect the blockage of the aeration hole and feed back to the control module. The control module automatically adjusts the intensity and working time of the ultrasonic wave according to the feedback from the detection sensor to achieve efficient cleaning.

[0006] Preferably, the detection sensor is a flow sensor for detecting the flow in the aeration pipe. When the aeration hole is blocked, the flow in the aeration pipe decreases, and the control module can determine whether blockage occurs based on the flow reduction.

[0007] Preferably, the detection sensor is a pressure sensor for detecting the pressure in the aeration pipe. The pressure sensor is installed on the pipe wall of the aeration pipe. When the aeration hole is blocked, the liquid pressure in the aeration pipe increases. The control module can determine whether blockage has occurred according to the pressure change. The threshold of the pressure difference can be set. If the threshold is exceeded, it is determined that blockage has occurred. The degree of blockage is determined by monitoring the pressure difference before and after the aeration hole.

[0008] Preferably, the ultrasonic vibrator is arranged near the aeration hole and arranged at intervals. The closer the ultrasonic vibrator is to the aeration hole, the better the vibration cleaning effect is.

[0009] Preferably, the shell of the ultrasonic vibrator is made of corrosion-resistant material and has an appropriate waterproof grade to adapt to the humid environment of the aerated grit chamber.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model sets a number of ultrasonic vibrators and detection sensors on the aeration pipe, detects the blockage of the aeration hole in time through the detection sensor, controls the action of the ultrasonic generator through the control module, and makes the ultrasonic vibrator vibrate to clean and dredge the blockage of the aeration hole.

[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, a plurality of aeration tubes 2 are provided at the bottom of the aeration grit chamber 1, and an ultrasonic automatic cleaning device for an aeration grit chamber includes a plurality of ultrasonic vibrators 4 and detection sensors 5 arranged on the aeration tubes 2, as well as an ultrasonic generator and a control module; the ultrasonic vibrator 4 is connected to the ultrasonic generator, the detection sensor 5 and the ultrasonic generator are electrically connected to the control module, and the detection sensor 5 is used to detect the blockage of the aeration hole 3 and feed back to the control module. The control module automatically adjusts the intensity and working time of the ultrasonic wave according to the feedback of the detection sensor 5 to achieve efficient cleaning. The detection sensor 5 is installed on the outer wall of the aeration tube 2 to detect the blockage in an indirect manner. The control module connects all ultrasonic vibrators 4 and is connected to the ultrasonic generator through a cable. The module is responsible for receiving data from the detection sensor 5 and adjusting the intensity and emission frequency of the ultrasonic wave according to the data to achieve the best cleaning effect.

[0018] The detection sensor 5 is arranged below the aeration hole 3 area.

[0019] The detection sensor 5 may be a flow sensor for detecting the flow in the aeration tube 2. When the aeration hole 3 is clogged, the flow in the aeration tube 2 decreases, and the control module may determine whether a blockage occurs according to the decrease in flow.

[0020] The detection sensor 5 can also be a pressure sensor for detecting the pressure in the aeration tube 2. The pressure sensor is installed on the wall of the aeration tube 2. When the aeration hole 3 is blocked, the liquid pressure in the aeration tube 2 increases. The control module can determine whether a blockage has occurred based on the change in pressure. The threshold of the pressure difference can be set. If the threshold is exceeded, it is determined that a blockage has occurred. It is suitable for occasions where the blockage of the aeration hole 3 needs to be accurately detected. The degree of blockage can also be determined by monitoring the pressure difference before and after the aeration hole 3. When the pressure sensor is installed on the wall of the aeration tube 2, a sealing gasket is used, and a suitable fixing device such as a clamp or screw is used to ensure a tight seal without leakage risk. The pressure sensor monitors the pressure changes in real time and transmits the data to the control module.

[0021] Trigger cleaning mechanism: Once a blockage is detected, the control module automatically triggers the ultrasonic generator, adjusts the ultrasonic intensity and frequency, and uses the sound wave energy to destroy the structure of the blockage, thereby clearing the blockage. The ultrasonic vibrator 4 is set near the aeration hole 3 and is set at intervals. The closer the ultrasonic vibrator 4 is set to the aeration hole 3, the better the vibration cleaning effect. The shell of the ultrasonic vibrator 4 is made of corrosion-resistant material and has an appropriate waterproof grade to adapt to the humid environment of the aeration tank.

[0022] In normal operation, the control module regularly receives and analyzes the data from the detection sensor 5. When it is detected that the aeration hole 3 begins to be slightly blocked, ultrasonic cleaning is automatically started.

[0023] The frequency and power of the ultrasonic wave can be automatically adjusted according to the degree of blockage, ensuring that the blockage is effectively removed without damaging the aeration tube 2.

[0024] The cleaning process does not require downtime and will not affect the water quality, and can achieve efficient cleaning of the aerated grit chamber 1 that operates continuously for 24 hours.
