Abstract
Description
Technical Field
[0001] This invention relates to the field of foam elimination technology, specifically a spray defoaming device. Background Technology
[0002] In many fields such as industrial wastewater treatment, chemical production, and papermaking, large amounts of foam are easily generated when liquids contain surfactants or when aeration or stirring is performed. Excessive foam accumulation not only affects production efficiency, such as causing holes and breaks in paper sheets in papermaking and affecting the transport of mineralized foam in mineral processing, but also causes environmental pollution, equipment corrosion, and occupies effective processing space.
[0003] Existing defoaming methods mainly include chemical defoaming and mechanical defoaming. Chemical defoaming requires continuous addition of defoaming agents, resulting in high operating costs and potential secondary pollution to water quality or products. While mechanical defoaming is environmentally friendly, existing devices often suffer from problems such as small spray coverage area, dead corners, and easy clogging of nozzles, leading to incomplete defoaming and unstable effects.
[0004] Therefore, a spray defoaming device is needed to solve the problems of limited coverage area, dead corners in defoaming, and unstable defoaming effect caused by easy clogging of nozzles in the existing technology. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a spray defoaming device that has the advantages of increasing the spray coverage area and providing a stable defoaming effect, thus solving the problems mentioned in the background art.
[0006] The present invention provides the following technical solution: a spray defoaming device, comprising a spray pipe, a plurality of nozzles installed at the bottom of the spray pipe, guide components for guiding the spray pipe on both sides, a drive component for driving the spray pipe on one side, a hose fixedly connected to the input end of the spray pipe via a connector, a spray pump connected to the input end of the hose, a water pump fixedly connected to the output end of the spray pump, a water pumping pipe fixedly provided at the input end of the spray pump, a water tank fixedly connected to the bottom end of the spray pump, and a filter screen one and a filter screen two fixedly provided sequentially inside the water tank, wherein the filter holes of the filter screen two are smaller than those of the filter screen one.
[0007] As a preferred embodiment of the present invention, the guide assembly includes a sliding sleeve, the top of which is fixedly connected to the spray pipe, a guide rod is slidably connected to the sliding sleeve, and supports are fixedly provided at both ends of the guide rod. The bottom end of the support is fixedly connected to the top end of the pool body by bolts.
[0008] As a preferred embodiment of the present invention, the drive assembly includes a protective cover and a transmission belt. A drive wheel is rotatably provided on one side of the protective cover, and a driven wheel is rotatably provided on the other side of the protective cover. The driven wheel is connected to the drive wheel via the transmission belt. A connecting block is fixedly connected to the transmission belt, and a connecting rod is fixedly provided at the bottom end of the connecting block. One end of the connecting rod is fixedly connected to one side of the spray pipe.
[0009] As a preferred embodiment of the present invention, the bottom end of the protective cover is provided with a channel corresponding to the connecting rod, and a forward and reverse motor for driving the drive wheel is fixedly installed on one side of the protective cover.
[0010] As a preferred embodiment of the present invention, mounting plates are fixedly provided on both sides of the protective cover, and one side of the mounting plate is fixedly connected to the top of the side wall of the pool by bolts.
[0011] As a preferred embodiment of the present invention, a groove is provided on one side of the top of the water tank, and the input end of the water pumping pipe passes through the groove and is placed inside the water tank.
[0012] As a preferred embodiment of the present invention, a drain valve one and a drain valve two for discharging filtered material are fixedly installed at the bottom of one side of the water tank. The drain valve one is located on one side of the filter screen one, and the drain valve two is located between the filter screen one and the filter screen two.
[0013] As a preferred embodiment of the present invention, a water inlet is provided on one side of the top of the water tank, and a water supply pipe is fixedly provided at the top of the water inlet.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This spray defoaming device, through the setting of a drive component and a guide component, drives the spray pipe to move back and forth along the guide component, so that multiple nozzles on the spray pipe can dynamically sweep the entire pool surface during the movement, which greatly increases the spray coverage area of a single set of devices, eliminates the dead corners that exist in fixed spraying, and makes the defoaming effect more thorough and stable. By setting filter screens one and two with different filter pore sizes inside the water tank, a double-layer filtration structure is formed, which can effectively intercept large particulate impurities and fine suspended matter in the spray water, greatly reducing the risk of nozzle clogging, ensuring long-term stable operation of the device, and reducing the frequency of maintenance.
[0015] 2. This spray defoaming device connects the spray pipe and the spray pump via a flexible hose. The hose is highly flexible and can adapt to the reciprocating movement of the spray pipe, ensuring uninterrupted water supply during movement without interfering with the movement of the spray pipe. By setting drain valve one and drain valve two, large particles intercepted by filter screen one and fine particles deposited between filter screen one and filter screen two can be periodically discharged, making cleaning convenient and helping to maintain the cleanliness of the water in the tank.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1-5The spray defoaming device includes a spray pipe 1 for conveying spray water. Several nozzles 2 are installed at the bottom of the spray pipe 1. The nozzles 2 are preferably fan-shaped or spiral nozzles, capable of dispersing high-pressure water into fine droplets to form an effective defoaming water curtain. Guide components 3 are provided on both sides of the spray pipe 1 to guide it, ensuring stable and linear movement during its movement. A drive component 4 is provided on one side of the spray pipe 1 to power its reciprocating movement. A flexible hose 5 is fixedly connected to the input end of the spray pipe 1 via a connector. The flexible hose 5 is made of high-pressure wear-resistant tubing with good flexibility, capable of moving with the spray pipe. The hose 1 moves and bends to ensure continuous water supply. The input end of the hose 5 is connected to the spray pump 6, and the output end of the spray pump 6 is fixedly connected to the hose 5. The input end of the spray pump 6 is fixedly equipped with a water pumping pipe 8, and the bottom end of the spray pump 6 is fixedly connected to a water tank 7 for storing spray water. Inside the water tank 7, filter screen 10 and filter screen 21 are fixedly installed in sequence. The filter holes of filter screen 211 are smaller than those of filter screen 10. Filter screen 10 is used to intercept larger suspended solids and particulate impurities in the water, and filter screen 21 is used to further filter fine silt and suspended solids. The clean water after two stages of filtration is drawn by the spray pump 6 and transported to the spray head 2, effectively preventing the spray head 2 from clogging. In this embodiment, preferably, the guide component 3 includes a sliding sleeve 301, the top of which is fixedly connected to the spray pipe 1, and a guide rod 302 is slidably connected to the sliding sleeve 301. The guide rod 302 provides a guide path for the movement of the spray pipe 1. Both ends of the guide rod 302 are fixedly provided with supports 303, and the bottom end of the support 303 is fixedly connected to the top of the pool body by bolts, so that the entire guide component 3 is stably installed on the pool body. In this embodiment, preferably, the drive assembly 4 includes a protective cover 401 and a transmission belt 404. A drive wheel 402 is rotatably mounted on one side of the protective cover 401, and a driven wheel 403 is rotatably mounted on the other side of the protective cover 401. The driven wheel 403 is connected to the drive wheel 402 via the transmission belt 404. A connecting block 405 is fixedly connected to the transmission belt 404. A connecting rod 406 is fixedly mounted at the bottom end of the connecting block 405. One end of the connecting rod 406 is fixedly connected to one side of the spray pipe 1. A channel corresponding to the connecting rod 406 is opened at the bottom end of the protective cover 401. A channel for the drive wheel 402 is fixedly mounted on one side of the protective cover 401. The forward and reverse motor 407 is driven to rotate. When the forward and reverse motor 407 is started, it drives the drive wheel 402 to rotate. The drive wheel 402 drives the driven wheel 403 to rotate synchronously through the transmission belt 404. The connecting block 405 on the transmission belt 404 moves accordingly, and then drives the spray pipe 1 to move linearly along the guide rod 302 through the connecting rod 406. By controlling the direction switching of the forward and reverse motor 407, the reciprocating movement of the spray pipe 1 can be realized. The protective cover 401 is fixedly provided with mounting plates 408 on both sides. One side of the mounting plate 408 is fixedly connected to the top of the side wall of the pool body by bolts, so that the drive assembly 4 is firmly installed on the pool body. In this embodiment, preferably, a pipe groove is provided on one side of the top of the water tank 7, and the input end of the water pumping pipe 8 passes through the pipe groove and is placed inside the water tank 7 to ensure that the water pumping pipe 8 can extend below the water surface to pump water normally. A water supply port is provided on one side of the top of the water tank 7, and a water supply pipe 9 is fixedly provided at the top of the water supply port for replenishing fresh water to the water tank 7 or connecting to recycled water. In this embodiment, preferably, a drain valve 12 and a drain valve 13 for discharging filtered material are fixedly installed at the bottom of one side of the water tank 7. The drain valve 12 is located on one side of the filter screen 10 and is used to discharge large particulate impurities intercepted by the filter screen 10. The drain valve 13 is located between the filter screen 10 and the filter screen 11 and is used to discharge fine impurities deposited between the two filter screens. By periodically opening the drain valves, the pollutants trapped by filtration can be conveniently discharged from the water tank 7, keeping the water tank 7 clean and maintaining the filtration effect.
[0020] In use, first, according to the size of the defoaming tank, fix the support 303 of the guide component 3 to the two sides of the tank wall at the top of the tank with bolts, ensuring that the guide rods 302 on both sides are parallel to each other and at the same horizontal height. Fix the protective cover 401 of the drive component 4 to the top of the side wall of the tank with the mounting plate 408, ensuring that the position of the drive component 4 corresponds to the drive end of the spray pipe 1. Fit the sliding sleeves 301 on both sides of the spray pipe 1 onto the guide rods 302, ensuring that the sliding sleeves 301 and the guide rods 302 slide smoothly. Fix one end of the connecting rod 406 to one side of the spray pipe 1. Connect one end of the hose 5 to the input end of the spray pipe 1 through a connector, and connect the other end to the output end of the spray pump 6. Insert the input end of the water pump 8 into the water tank 7 through the pipe groove at the top of the water tank 7. Connect the power cords of the forward and reverse motor 407 and the spray pump 6 to the control cabinet, and check whether the rotation direction of the forward and reverse motor 407 is consistent with the set direction. Spray water is injected into water tank 7 through water supply pipe 9. The water source can be industrial recycled water or clean water. After the water enters water tank 7, it is filtered by filter screen 10 and filter screen 21 in sequence. Large particles of impurities are intercepted on one side of filter screen 10, and fine suspended matter is deposited between filter screen 10 and filter screen 21. The filtered clean water is stored in water tank 7 for later use. Ensure that drain valve 12 and drain valve 213 are in the closed state to prevent water leakage. Start the spray pump 6. The spray pump 6 draws filtered clean water from the water tank 7 through the water pipe 8. After pressurization, it is delivered to the spray pipe 1 through the hose 5. The high-pressure water jet is finally sprayed out from the nozzle 2 at high speed, forming a defoaming water curtain above the liquid surface to initially break up the foam. Start the forward and reverse motor 407. The forward and reverse motor 407 drives the drive wheel 402 to rotate. The drive wheel 402 drives the driven wheel 403 to rotate synchronously through the transmission belt 404. The connecting block 405 on the transmission belt 404 moves accordingly. Through the connecting rod 406, the spray pipe 1 moves linearly along the guide rod 302. When the spray pipe 1 moves to one end of the set stroke, the timer or limit switch (which can be added) in the control cabinet automatically controls the forward and reverse motor 407 to reverse, thereby causing the spray pipe 1 to move in the opposite direction. This process is repeated to achieve automatic reciprocating movement of the spray pipe 1 above the pool surface. During the movement, the multiple nozzles 2 on the spray pipe 1 dynamically sweep the liquid surface below, covering the foam in the entire moving area and ensuring that there are no dead corners for defoaming.
