Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for eliminating foam inside a tank and a neutralizing liquid recovery tank. Background Technology

[0002] During the neutralization liquid recovery and preparation process at wastewater treatment plants, the raw materials used contain foaming agents and cleaning agents, which easily generate large amounts of foam during preparation and circulation pump operation. This foam accumulates continuously inside the tank, causing a series of serious problems.

[0003] Currently, infrared level detection is commonly used for monitoring liquid levels inside tanks. However, with the increase of foam, infrared level detection becomes severely interfered with. Foam scatters and reflects infrared light, causing the detected level information to differ from the actual level, resulting in false level readings. These false levels mislead operators' judgment of the actual neutralizing liquid level in the tank, leading to deviations in the amount of neutralizing liquid added. Adding too much may waste neutralizing liquid and increase treatment costs; adding too little will fail to achieve the expected neutralization effect, affecting the quality of wastewater treatment.

[0004] Meanwhile, false liquid levels can also cause localized pressure anomalies in the circulation system. During the operation of the circulating pump, inaccurate liquid level information can cause fluctuations in the pump's inlet and outlet pressures, affecting the pump's normal operation and reducing its service life. In severe cases, localized pressure anomalies may even lead to safety accidents, posing a significant threat to the normal production and operation of the wastewater treatment plant. Therefore, it is urgent to take effective measures to solve the foaming problem in the neutralization liquid recovery tank. Utility Model Content

[0005] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a device for eliminating foam in a tank and a neutralizing liquid recovery tank.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a device for eliminating foam inside a tank, comprising: First pipe section, second pipe section, and nozzle; One end of the first pipe section is connected to the pipeline in the neutralization liquid recovery tank. One end of the first pipe section is detachably connected to one end of the second pipe section. The other end of the second pipe section is detachably connected to the connection end of the nozzle. The spray end of the nozzle faces the inside of the neutralization liquid recovery tank. Main working principle: The foam elimination device inside the tank is mainly used to solve the foam problem caused by foaming adhesive and cleaning agent in the neutral liquid recovery tank during configuration, operation and circulation pump operation. Through reasonable design of the connection and structure of each component, water is accurately delivered to the foam area inside the tank, and the foam is eliminated by the impact force of the water flow, ensuring accurate liquid level monitoring in the neutral liquid recovery tank and normal operation of the equipment.

[0007] One end of the first pipe section is securely connected to the pipeline in the neutralization liquid recovery tank, providing a stable water inlet channel for the entire foam elimination device and ensuring that external water sources can smoothly enter the device. This connection method guarantees effective integration between the device and the tank's piping system, allowing water to flow unimpeded from outside the tank into the device.

[0008] The first pipe section is detachably connected to the second pipe section at the other end. This design facilitates the installation, disassembly, and maintenance of the device. During installation, the first and second pipe sections can be quickly assembled together; when the device malfunctions or requires cleaning, they can be easily separated for inspection or cleaning. The second pipe section, as the intermediate component connecting the first pipe section and the sprinkler head, primarily functions to stably transmit the water flow introduced from the first pipe section to the sprinkler head. The detachable connection between the second pipe section and the sprinkler head also facilitates installation and maintenance. When installing the sprinkler head, the appropriate sprinkler type and specifications can be selected according to actual needs and securely installed on the second pipe section using the detachable connection. In case of blockage or damage to the sprinkler head, it can be quickly disassembled and replaced, reducing equipment downtime.

[0009] The spray nozzles are positioned so that their spray ends face inwards towards the neutralizing liquid recovery tank; this is a key design feature that enables the entire device to eliminate foam. By controlling the nozzles' on / off state, the water flow from the nozzles can be ensured to directly target the foam-generating area within the tank, improving foam elimination efficiency. When water is sprayed from the nozzles, it forms a water jet with a certain speed and pressure. These water jets impact the foam within the tank, using the kinetic energy of the water flow to break up the foam, disrupting its structural stability and causing it to quickly dissipate. Simultaneously, the water flow also dilutes the liquid components within the foam, further reducing its stability and thus effectively eliminating it.

[0010] When foam is detected in the neutralizing solution recovery tank, affecting liquid level monitoring and normal equipment operation, an external water source is turned on. Water flows through the pipeline in the neutralizing solution recovery tank into the first pipe section. The water flows steadily in the first pipe section and then continues its transmission into the second pipe section. Finally, the water reaches the nozzle and sprays out from the spray end of the nozzle, directly impacting and eliminating the foam in the tank. As the foam is continuously eliminated, the liquid level in the tank returns to normal. Monitoring equipment such as infrared liquid level detection can accurately obtain the actual liquid level information, ensuring the safe and stable preparation and use of the neutralizing solution.

[0011] Preferably, one end of the first pipe section is a first pair of interfaces, the size and shape of which correspond to the size and shape of the pipe in the neutral liquid recovery tank, and the first pair of interfaces is fitted around the pipe in the neutral liquid recovery tank. The other end of the first pipe section is a second pair of interfaces, the size and shape of which correspond to the size and shape of the second pipe section. The second pair of interfaces is threadedly connected to one end of the second pipe section that faces the pipeline in the neutralized liquid recovery tank. The first pair of interfaces and the second pair of interfaces are interconnected.

[0012] Preferably, the first pipe section is provided with a retaining edge on its periphery, and when the first pipe section is connected to the second pipe section, the second pipe section and the retaining edge are pressed together.

[0013] Preferably, the nozzle has a groove at its docking section and a retaining edge at one end of the second pipe section facing the neutralizing liquid recovery tank. The nozzle and the second pipe section are locked together by the groove and the retaining edge.

[0014] Preferably, a sealing ring is fitted around the edge of the clamp, and the nozzle and the second pipe section are pressed against the sealing ring by the groove and the clamp.

[0015] Preferably, the spray end of the nozzle includes a water outlet pipe, a connecting rod, and a baffle. The water outlet pipe is connected to the second pipe section. Multiple connecting rods are provided, one end of each connecting rod is connected to the baffle, and the other end of each connecting rod is connected to the water outlet pipe. The baffle faces into the neutralization liquid recovery tank.

[0016] Preferably, the second pipe section is made of polytetrafluoroethylene.

[0017] A neutralizing liquid recovery tank includes: any of the above-described devices for eliminating foam inside the tank, a tank body, and pipelines; The foam elimination device inside the tank is installed above the tank body, and the foam elimination device inside the tank is connected to an external water source through the pipeline.

[0018] Specific working principle: This neutralization liquid recovery tank is mainly used to collect and store neutralization liquid. At the same time, the foam elimination device inside the tank effectively solves the foam problem caused by the characteristics of the neutralization liquid components during the preparation operation and circulation pump circulation process, ensuring accurate liquid level monitoring inside the tank and maintaining the stable operation of neutralization liquid recovery and subsequent processing.

[0019] The tank body is the main structure of the neutralization liquid recovery tank, providing a stable storage space for the neutralization liquid. It is typically made of corrosion-resistant materials to withstand the potential corrosiveness of the neutralization liquid, ensuring the tank body remains undamaged during long-term use and guaranteeing the safe storage of the neutralization liquid.

[0020] When foam is generated inside the tank, an external water source supplies water to the foam-eliminating device inside the tank through pipelines. The water flows sequentially through the first pipe section, the second pipe section, and finally reaches the nozzle. The nozzle sprays the water at a specific angle and pressure, forming a water jet with a certain kinetic energy. These water jets impact the foam inside the tank, disrupting the surface film structure of the foam and causing it to quickly break down and dissipate. At the same time, the water flow also dilutes the liquid components in the foam, further reducing its stability, thereby achieving the purpose of completely eliminating the foam. The pipeline is the channel connecting the external water source and the foam-eliminating device inside the tank; its function is to stably deliver water from the external source to the foam-eliminating device inside the tank. The pipeline is usually made of pressure-resistant and corrosion-resistant materials to ensure that there will be no leakage or damage during water delivery, guaranteeing the normal water supply to the device.

[0021] Preferably, the pipeline is a PVC pipe.

[0022] Compared with the prior art, the beneficial effects of this utility model are: This invention enables water to be sprayed from a nozzle. When the water impacts the foam inside the tank, its powerful kinetic energy quickly breaks down the surface film structure of the foam, disrupting its stability and causing it to dissipate rapidly. This effectively solves the problem of foam accumulation caused by foaming adhesives and cleaning agents in the neutralization liquid recovery tank. The spray nozzle's spray end faces the inside of the neutralization liquid recovery tank, and its installation position and angle can be adjusted according to actual needs to ensure that the water flow can fully cover all foam areas inside the tank. Foam generated at the top, side walls, or bottom of the tank can be effectively impacted by the water flow, preventing foam residue and improving the thoroughness of foam elimination.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Example 1 This embodiment discloses a device for eliminating foam inside a can, such as... Figure 1 As shown, it includes a first pipe section 1, a second pipe section 2, and a nozzle 3. It is mainly used to solve the foam problem generated in the neutral liquid recovery tank due to the presence of foaming adhesive and cleaning agent during configuration, operation, and circulation pump operation. By reasonably designing the connection and structure of each component, water is accurately delivered to the foam area in the tank, and the water flow impact force is used to eliminate the foam, ensuring accurate liquid level monitoring in the neutral liquid recovery tank and normal operation of the equipment.

[0028] One end of the first pipe section 1 is securely connected to pipe 5 in the neutralization liquid recovery tank, providing a stable water inlet channel for the entire foam elimination device and ensuring that external water sources can smoothly enter the device. This connection method ensures effective docking between the device and the pipe 5 system of the tank 4, allowing water to flow unimpeded from outside the tank 4 into the device.

[0029] The other end of the first pipe section 1 is detachably connected to the second pipe section 2. This design facilitates the installation, disassembly, and maintenance of the device. During installation, the first pipe section 1 and the second pipe section 2 can be quickly assembled together; when the device malfunctions or needs cleaning, they can also be easily separated for inspection or cleaning. The second pipe section 2, as the intermediate component connecting the first pipe section 1 and the nozzle 3, primarily functions to stably transmit the water flow introduced from the first pipe section 1 to the nozzle 3. The detachable connection between the second pipe section 2 and the nozzle 3 is also for ease of installation and maintenance. When installing the nozzle 3, the appropriate nozzle type and specification can be selected according to actual needs and securely installed on the second pipe section 2 via the detachable connection. If the nozzle 3 becomes clogged or damaged, it can also be quickly disassembled and replaced, reducing equipment downtime.

[0030] The spray tip of nozzle 3 faces the interior of the neutralizing liquid recovery tank 4, which is a key design feature of the entire device to achieve its foam elimination function. By controlling the on / off state of nozzle 3, it is ensured that the water flow from nozzle 3 directly acts on the foam-generating area inside the tank, improving the efficiency of foam elimination. When the water flow is sprayed from nozzle 3, it forms a water jet with a certain speed and pressure. These water jets impact the foam inside the tank, using the kinetic energy of the water flow to break up the foam, disrupt its structural stability, and cause it to quickly dissipate. At the same time, the water flow can also dilute the liquid components in the foam, further reducing its stability, thereby effectively eliminating the foam.

[0031] When foam is detected in the neutralizing solution recovery tank, affecting liquid level monitoring and normal equipment operation, an external water source is turned on. Water enters the first pipe section 1 through pipe 5 in the neutralizing solution recovery tank. The water flows steadily in the first pipe section 1 and then continues its flow into the second pipe section 2. Finally, the water reaches the nozzle 3 and sprays out from the spray end of the nozzle 3, directly impacting and eliminating the foam in the tank. As the foam is continuously eliminated, the liquid level in the tank returns to normal. Monitoring equipment such as infrared liquid level detection can accurately obtain the actual liquid level information, ensuring the safe and stable preparation and use of the neutralizing solution. In some optional embodiments, the size and shape of the first pair of interfaces 10 correspond to the pipes 5 in the neutralizing liquid recovery tank. By fitting them around the periphery, friction and a certain interference fit are used to ensure that the first pipe section 1 can be tightly connected to the pipes 5 inside the tank, ensuring that water flows smoothly from the pipes 5 inside the tank into the first pipe section 1, and that the connection is not easy to loosen or leak. Of course, the size and shape of the first pair of interfaces 10 can also be connected to the pipes 5 in the neutralizing liquid recovery tank by threads, thereby further ensuring the stability of the connection.

[0032] The second pair of interfaces 11 is threadedly connected to the end of the second pipe section 2 facing the inner pipe 5 of the tank. When the second pipe section 2 is rotated to engage with the threads of the second pair of interfaces 11, a tight connection is ensured, facilitating installation and disassembly, and making subsequent maintenance and repair of the device convenient. Furthermore, the first pair of interfaces 10 and the second pair of interfaces 11 are interconnected, ensuring that water can flow smoothly through the first pipe section 1.

[0033] In some optional embodiments, a retaining flange 12 is provided around the periphery of the first pipe segment 1. When the first pipe segment 1 is connected to the second pipe segment 2, the second pipe segment 2 will press against the retaining flange 12. The retaining flange 12 serves as a limit to prevent the second pipe segment 2 from moving axially after connection. At the same time, it increases the contact area at the connection, which improves the sealing effect to a certain extent and reduces the possibility of water leakage from the connection.

[0034] In some optional embodiments, the nozzle 3 has a groove 30 at its mating section, and the second pipe section 2 has a retaining edge 20 at its end facing the inside of the tank. During installation, the retaining edge 20 of the second pipe section 2 is aligned with the groove 30 of the nozzle 3, and a certain external force is applied to make the retaining edge 20 snap into the groove 30. The mutual cooperation between the groove 30 and the retaining edge 20 tightly connects the nozzle 3 and the second pipe section 2 together. This snap-fit ​​method facilitates installation and disassembly without the need for complex tools, thus improving installation efficiency.

[0035] In some optional embodiments, a sealing ring 21 is fitted around the edge 20. When the nozzle 3 and the second pipe section 2 are tightly engaged with each other through the groove 30 and the edge 20, the sealing ring 21 is compressed. Under pressure, the sealing ring 21 undergoes elastic deformation, filling the tiny gap between the groove 30 and the edge 20, forming a tight sealing barrier. This effectively prevents water leakage from the connection point, ensuring that all water can be sprayed from the nozzle 3 to eliminate foam.

[0036] In some optional embodiments, the spray end of the nozzle 3 consists of a water outlet pipe 31, connecting rods 32, and a baffle 33. The water outlet pipe 31 is connected to the second pipe section 2, introducing water flow into the spray end. Multiple connecting rods 32 are connected at one end to the baffle 33 and at the other end to the water outlet pipe 31, serving to support the baffle 33. The baffle 33 faces inward into the tank. When water flows out from the water outlet pipe 31, it impacts the baffle 33, causing the water flow to disperse into finer droplets or a water curtain through the gaps in the connecting rods 32, expanding the coverage area of ​​the water flow, thereby more effectively impacting the foam in various locations inside the tank and enhancing the foam elimination effect.

[0037] In some optional embodiments, the second pipe section 2 is made of polytetrafluoroethylene (PTFE). PTFE has excellent corrosion resistance and can resist the erosion of various chemicals that may be contained in the neutralizing liquid. At the same time, it also has good high-temperature and low-temperature resistance and can maintain stable performance over a wide temperature range. In addition, the smooth surface of PTFE and the low coefficient of friction can reduce the resistance of water flow in the pipe section, ensure smooth water flow, and reduce energy loss.

[0038] Example 2 This embodiment discloses a neutralization liquid recovery tank, such as Figure 2 As shown, the neutralizing liquid recovery tank includes any of the above-mentioned foam elimination devices, tank body 4, and pipeline 5. The neutralizing liquid recovery tank is mainly used to collect and store neutralizing liquid. At the same time, the foam elimination device effectively solves the foam problem generated in the tank due to the characteristics of the neutralizing liquid components during the preparation operation and circulation pumping process, ensuring accurate monitoring of the liquid level in the tank and maintaining the stable operation of the neutralizing liquid recovery and subsequent processing.

[0039] Tank 4 is the main structure of the neutralization liquid recovery tank, providing a stable storage space for the neutralization liquid. Its material is typically corrosion-resistant to withstand the potential corrosiveness of the neutralization liquid, ensuring that tank 4 remains undamaged during long-term use and guaranteeing the safe storage of the neutralization liquid.

[0040] When foam is generated inside the tank, an external water source supplies water to the foam-eliminating device inside the tank through pipe 5. The water flows sequentially through the first pipe section 1, the second pipe section 2, and finally reaches the nozzle 3. The nozzle 3 sprays the water at a specific angle and pressure, forming a water jet with a certain kinetic energy. These water jets impact the foam inside the tank, destroying the surface film structure of the foam and causing it to quickly break down and dissipate. At the same time, the water flow can also dilute the liquid components in the foam, further reducing the stability of the foam, thereby achieving the purpose of completely eliminating the foam. Pipe 5 is the channel connecting the external water source and the foam-eliminating device inside the tank. Its function is to stably deliver water from the external water source to the foam-eliminating device inside the tank. The material of pipe 5 is usually selected to be pressure-resistant and corrosion-resistant to ensure that there will be no leakage or damage during the water flow process, ensuring the normal water supply of the device.

[0041] In some optional embodiments, pipe 5 is made of PVC pipe. PVC pipe has good corrosion resistance and can resist the erosion of impurities and chemicals that may be contained in the water, ensuring the service life of the pipe. It is also lightweight and easy to install, making it easy to arrange and connect on the neutralization liquid recovery tank. At the same time, the inner wall of PVC pipe is smooth and the water flow resistance is low, which can ensure that the water flows smoothly through the pipe into the foam elimination device in the tank, providing a stable water supply for foam elimination.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
