Description

Technical Field

[0001] This utility model belongs to the field of probe cleaning technology, and in particular relates to a two-in-one device and system that integrates the discharge of condensate from aeration pipes and the automatic cleaning of underwater probes. Background Technology

[0002] Currently, manual cleaning is the most common method for cleaning online instrument probes. This method has several problems, such as: probes are usually fixed in inconvenient locations like underwater, making manual retrieval time-consuming, labor-intensive, and posing safety hazards; manual cleaning cannot guarantee cleaning effectiveness; frequent probe movement may damage the probe and lead to inaccurate measurements. Taking a wastewater treatment plant as an example, manual cleaning of instrument probes requires two operators: one person leans out of the railing to remove the probe holder, lifts the probe vertically out of the water, and places it horizontally on the ground; the other person carries a bucket of clean water, wipes the probe surface clean with a damp cloth, and then puts the probe back in. This method requires manpower, poses safety hazards such as falls while working above the pool, and the use of cloths during manual cleaning can easily scratch the instrument probe. Furthermore, the cleaning method is simplistic and cannot guarantee cleaning effectiveness.

[0003] The wastewater treatment plant's AAO biological system uses blowers for continuous aeration to provide air to the aerobic tank, ensuring a normal dissolved oxygen concentration. Simultaneously, aeration provides stirring power for the sludge in the aerobic tank, ensuring uniform mixing of sludge and water. The aeration pipeline is equipped with a condensate drain line to discharge condensate that accumulates due to temperature and pressure variations. Failure to drain condensate in a timely manner will cause increased blower back pressure and energy consumption; excessive condensate accumulation will reduce the aeration efficiency of the aerobic tank. Therefore, timely condensate drainage is crucial for the normal operation of the AAO biological system. Currently, condensate drainage requires manual opening of the response valve to discharge the air-water mixture.

[0004] Therefore, based on the above problems, designing an automatic and efficient two-in-one solution that can utilize the water and air sources from the condensate drain pipe to clean underwater instrument probes is of significant practical importance. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a two-in-one device and system that integrates the discharge of condensate from aeration pipes and automatic cleaning of underwater probes. Its design aims to provide an efficient and automated cleaning solution, which is particularly suitable for cleaning precision instrument probes. This new cleaning method offers many convenient improvements, such as freeing up manpower, timed cleaning, and eliminating the need to move the probe, thereby saving manpower and material costs.

[0006] The technical solution adopted by this utility model to solve this problem is:

[0007] A two-in-one device integrating the discharge of condensate from aeration pipes and automatic cleaning of underwater probes, comprising:

[0008] The supporting structure has an assembly position for assembling the probe in the upper center and contains an ultrasonic vibrator and an ultrasonic mud level gauge. The probe is arranged vertically opposite to the ultrasonic vibrator in the assembled state.

[0009] The jet cleaning structure includes multiple horn-shaped nozzles arranged in multiple directions around the outer periphery of the assembly position and jet pipes for supplying air to the corresponding horn-shaped nozzles. The jet pipes are at least two in number, connected to the same air source and supplied with air independently.

[0010] In the above technical solution, the supporting structure is a U-shaped structure with two interlocking stainless steel square boxes as the supporting body, which is divided into two upper parts and one lower part.

[0011] In the above technical solution, the assembly position is an opening at the top center of the lower half of the load-bearing structure. The diameter of the assembly position is slightly larger than the diameter of the probe. A sealing strip is embedded in the edge of the assembly position, and the two sides are fastened with screws.

[0012] In the above technical solution, the ultrasonic mud level gauge is vertically installed in the lower half of the supporting structure, and an ultrasonic vibrator is fixed at the bottom center of the lower half of the supporting structure.

[0013] In the above technical solution, the horn-shaped nozzle is set at a 45° angle, and each of the horn-shaped nozzles surrounds the outer periphery of the assembly position with different spray directions, and each of the horn-shaped nozzles is connected to the corresponding jet pipeline.

[0014] In the above technical solution, the jet pipe is divided into at least two branches at the air source and arranged in an up-down direction. Each jet pipe is equipped with its own condensate drain manual valve and solenoid valve, so that each branch can operate independently.

[0015] In the above technical solution, the jet pipe is split into two paths at the air source, namely an upper air pipe and a lower air pipe. The upper air pipe is split into two paths again from the input end, and after extending into the supporting structure, it is connected to the corresponding horn-shaped nozzle. The lower air pipe is split into two paths again from the input end, and after extending into the supporting structure, it is connected to the corresponding horn-shaped nozzle.

[0016] In the above technical solution, the supporting structure is provided with a circular hole for inserting the jet pipe, wherein: the two holes on the upper side of the supporting structure are respectively for the two branches of the upper air pipe to pass through, and the two holes on the lower side are respectively for the two branches of the lower air pipe to pass through.

[0017] In the above technical solution, the gas source and the AAO biochemical system share a common gas source and are connected to a cleaning water source. The cleaning water source is the condensate from the aeration pipeline of the AAO biochemical tank, which is the condensate generated inside the aeration pipeline of the AAO biochemical tank.

[0018] The second objective of this invention is to provide a control system for a two-in-one device that integrates the discharge of condensate from aeration pipes and the automatic cleaning of underwater probes. The control system includes a solenoid valve control unit and an ultrasonic control unit. The solenoid valve control unit includes a time control circuit, which works in conjunction with the solenoid valve to control the timed switching of the solenoid valve. The ultrasonic control unit includes a mud level control circuit, which works in conjunction with an ultrasonic mud level gauge and an ultrasonic oscillator to control the opening and closing of the ultrasonic oscillator.

[0019] The advantages and positive effects of this utility model are:

[0020] 1. The advantages of this utility model are as follows:

[0021] High efficiency: The pressurized air-water mixture in the aeration pipeline is used to clean the underwater instrument probe, which can quickly and effectively remove dirt and impurities from the probe surface.

[0022] Automation: The cleaning process is automated through precise control of solenoid valves, reducing manual operation, ensuring cleaning effect, and improving cleaning efficiency;

[0023] Environmentally friendly: The entire cleaning process does not cause damage to the environment, making it an environmentally friendly device.

[0024] 2. This invention can share an air source system with the AAO biological treatment tank, saving on equipment and air source costs. Furthermore, the condensate discharge point can be used as a cleaning water source, enabling both air washing and dual air-water washing, doubling the cleaning effect. Additionally, the jet pipe of this invention can be connected to the condensate exhaust pipe of the AAO biological treatment tank, serving both as a water flushing probe and a discharge point for condensate from the AAO biological treatment system's aeration pipes—a dual benefit.

[0025] 3. This utility model uses an ultrasonic sludge level gauge. By measuring the time difference between the ultrasonic sensor's emission and reflection, the distance between the material and the sensor can be calculated, thereby determining the height of the sludge layer, judging the sludge layer thickness, and avoiding ineffective actions.

[0026] 4. This utility model uses an ultrasonic oscillator to break and disperse sludge particles, making them evenly distributed in the liquid, improving reaction efficiency and uniformity. By generating tiny bubbles in the liquid and causing the bubbles to collapse, ultrasonic vibration can generate strong negative pressure suction and impact force, causing dirt on the surface and in crevices of objects to be quickly peeled off, achieving the effects of removing stubborn dirt and disinfection.

Detailed Implementation

[0033] First, it should be noted that the specific structure, features, and advantages of this utility model will be described in detail below by way of examples. However, all descriptions are for illustrative purposes only and should not be construed as limiting the utility model in any way. Furthermore, any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the accompanying drawings, can still be arbitrarily combined or deleted among these technical features (or their equivalents) to obtain more other embodiments of this utility model that may not be directly mentioned herein. Additionally, for the sake of simplifying the drawings, the same or similar technical features may be indicated only in one place in the same drawing.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," and "screw-on" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The following will be combined with... Figures 1-4 This invention will now be described in detail. Example 1

[0035] A two-in-one device integrating the discharge of condensate from the aeration pipes of an AAO biochemical system and the automatic cleaning of underwater probes, comprising a support structure and a jet cleaning structure, wherein:

[0036] The supporting structure has an assembly position for assembling the probe 1 in the upper center and contains an ultrasonic vibrator 2 and an ultrasonic mud level gauge 3. The probe 1 is arranged vertically opposite to the ultrasonic vibrator 2 in the assembled state.

[0037] The jet cleaning structure includes multiple horn-shaped nozzles 4 arranged in multiple directions around the outer periphery of the assembly position and jet pipes for supplying air to the corresponding horn-shaped nozzles 4. The jet pipes are at least two in number, connected to the same air source 5 and supplied with air independently.

[0038] Furthermore, in this embodiment, one could also consider, such as Figure 1-2 As shown, the supporting structure 6 is a U-shaped structure with two interlocking stainless steel square boxes as the supporting body, which is divided into two upper parts 601 and one lower part 602.

[0039] Furthermore, in this embodiment, the assembly position can be considered as an opening at the top center of the lower half 602 of the load-bearing structure. The diameter of the assembly position is slightly larger than the diameter of the probe 1. A sealing strip is embedded in the edge of the assembly position, and the two sides are fastened with screws.

[0040] Furthermore, in this embodiment, the ultrasonic mud level gauge 3 is vertically arranged within the lower half 602 of the supporting structure, and an ultrasonic vibrator 2 is fixed at the bottom center of the lower half 602 of the supporting structure, wherein:

[0041] The function of an ultrasonic vibrator: When ultrasound propagates in a liquid, the dramatic change in sound pressure causes intense cavitation and emulsification, generating millions of tiny cavitation bubbles per second. These bubbles are rapidly generated in large quantities under the influence of sound pressure and continuously and violently burst, producing powerful impact force and negative pressure suction, which is sufficient to remove stubborn dirt.

[0042] The function of ultrasonic sludge level gauges: Through precise time measurement and sound velocity calculation, they can achieve high-precision interface position measurement. They support multiple variable output methods, including 4-20mA transmitter output, relay high / low alarm control output, and RS485 communication output, meeting the diverse needs of different users. Installation methods are flexible, including suspended, fixed, and insertion types, and cleaning and maintenance are simple, reducing the burden on users. By accurately monitoring and controlling the sludge treatment process, ultrasonic sludge level gauges help reduce energy consumption in wastewater treatment, achieving environmental protection and energy conservation goals.

[0043] Furthermore, in this embodiment, the horn-shaped nozzles 4 are arranged at a 45° angle, and each horn-shaped nozzle 4 surrounds the outer periphery of the assembly position / probe 1 with different spray directions, and each horn-shaped nozzle 4 is connected to a corresponding jet pipeline. For example... Figure 1-2 As shown, probe 1 has two nozzles on each side, one above the other. The two nozzles on the upper left and right are upper air jet nozzles, and the two nozzles on the lower left and right are lower air jet nozzles. The nozzles are trumpet-shaped, with a narrow inlet and a wide outlet. The angle of the upper and lower nozzles is 45° towards the probe.

[0044] Furthermore, in this embodiment, the jet pipe route can be divided into at least two branches at the gas source, arranged vertically. Each jet pipe route is equipped with its own condensate drain valve 7 and solenoid valve 8, allowing each route to operate independently. The solenoid valve ensures smooth gas transmission and controls the connection and disconnection between the gas outlet and the high-pressure gas source, achieving precise airflow control.

[0045] Furthermore, in this embodiment, the jet pipe 9 can be split into two paths at the air source 5: an upper air pipe 901 and a lower air pipe 902. The upper air pipe 901 splits into two paths from its input end, extending into the supporting structure and connecting to the corresponding trumpet-shaped nozzle 4. Similarly, the lower air pipe 902 splits into two paths from its input end, extending into the supporting structure and connecting to the corresponding trumpet-shaped nozzle 4. This dual-path jet cleaning structure effectively cleans stubborn sludge from the probe surface, providing several times the cleaning power of a single-path rinse. The trumpet-shaped nozzles rapidly disperse the liquid into fine droplets, forming a large-area, fine, and uniform mist cloud. This uniform spray effect helps improve the coverage and efficiency of the spray. Compared to vertical or horizontal spraying, 45° angle spraying reduces dead zones, ensuring that every corner receives sufficient spray coverage.

[0046] Furthermore, in this embodiment, the supporting structure may be provided with circular holes for inserting jet pipes, wherein: the two upper holes of the supporting structure are respectively for the two branches of the upper air pipe 901 to pass through, and the two lower holes are respectively for the two branches of the lower air pipe 902 to pass through.

[0047] Furthermore, in this embodiment, the gas source 5 can be considered to share a gas source with the AAO biochemical system and / or be connected to a cleaning water source. The cleaning water source is the condensate from the aeration pipe of the AAO biochemical tank, specifically the condensate generated within the aeration pipe. The gas source provides high-pressure gas to drive the cleaning process. The high-pressure gas ensures a strong airflow during the rinsing process, effectively removing stains and impurities from the probe surface. In selecting the gas source, our factory chose to share a gas source with the AAO biochemical tank. This saves equipment costs and allows for the provision of both cleaning gas and water sources via the condensate drain pipe, enabling both air-washing and dual-washing (air and water), doubling the cleaning effect. Alternatively, other types of gas sources can be used, such as high-pressure gas cylinders installed on-site or compressed gas sources using pneumatic valves. A blower or similar gas source can also be used, depending on the site conditions.

[0048] Working principle of Example 1: This device uses two interlocking stainless steel square boxes as the carrier. A hole is opened at the center of the top, with the diameter slightly larger than the probe diameter. Sealing strips are embedded in the edges, and both sides are secured with screws. The jet pipe is split into two paths at the air source, each equipped with its own condensate drain valve and solenoid valve, allowing each path to operate independently. Round holes the size of the air pipe are opened on the carrier structure for the jet pipe to pass through; the two upper holes are for the upper air pipe, and the two lower holes are for the lower air pipe. An ultrasonic vibrator is fixed at the center of the bottom of the carrier structure. This device is a two-in-one unit that integrates the discharge of condensate from the aeration pipe and automatic cleaning of the underwater probe. The air source is shared with the AAO (Automatic Angiography and Probe) system, and the probe water cleaning can also utilize the condensate generated from the aeration pipe (the condensate is clean water). The device has two air paths, one above the other. When the device is running, the air source is kept in the air intake state. The condensate drain valve is normally open and closed during maintenance. The solenoid valve works with the time control circuit to switch on and off at set times to achieve timed air blowing and timed cleaning. The ultrasonic mud level gauge determines the mud layer thickness and decides whether to start the ultrasonic oscillator. The air pipes serve as gas channels connecting the various parts. Example 2

[0049] The control system of the integrated device for discharging condensate from the aeration pipe of the AAO biochemical system and automatically cleaning the underwater probe, as described in Embodiment 1, includes a PLC controller, a solenoid valve control unit, and an ultrasonic control unit. The solenoid valve control unit includes a time control circuit, which works with the solenoid valve to control the timed switching of the solenoid valve. The ultrasonic control unit includes a mud level control circuit, which works with an ultrasonic mud level gauge and an ultrasonic oscillator to control the opening and closing of the ultrasonic oscillator.

[0050] In this embodiment, a two-in-one device that integrates the discharge of condensate from the aeration pipe and the automatic cleaning of the underwater probe mainly consists of seven parts: an air source, a condensate discharge manual valve, a solenoid valve, a time control circuit, an air jet pipeline, an ultrasonic vibrator, and an ultrasonic mud level gauge.

[0051] The operation steps include the following:

[0052] S1. The gas source is in a gas-filled state, and both manual valves are in the open state;

[0053] S2. The solenoid valve of the upper air pipe opens, starting the double steam and water wash from top to bottom. After the set time is reached, the solenoid valve of the upper air pipe closes.

[0054] S3. The solenoid valve of the lower air pipe opens, starting the steam-water double wash from bottom to top. After the set time is reached, the solenoid valve of the lower air pipe closes.

[0055] S4. The ultrasonic mud level gauge determines whether the mud layer thickness is greater than or equal to the preset value. If it is less than the preset value, proceed directly to step 6.

[0056] S5. When the mud layer thickness is greater than or equal to the preset value, the ultrasonic vibrator starts and stops after the set time is reached.

[0057] S6. The solenoid valve of the upper air pipe is opened, starting the double steam and water wash from top to bottom. After the set time is reached, the solenoid valve of the upper air pipe is closed, and step 4 is executed again.

[0058] This device can replace manual probe cleaning, starting at fixed times and locations, achieving efficiency unmatched by manual methods. It also completely eliminates the safety hazards associated with manual probe cleaning. Its advantages include:

[0059] High efficiency: The high-pressure steam-water mixture is used for cleaning, which can quickly and effectively remove stains and impurities from the probe surface.

[0060] Automation: The cleaning process is automated through precise control of solenoid valves, reducing manual operation and improving cleaning efficiency.
