Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fluid filtration, specifically designing a water filtration device. Background Technology
[0002] In the food processing industry, the water rinsing process requires a large amount of water, but the oil and residue carried by food can easily pollute the water, leading to water quality deterioration and frequent water changes. Purifying the water in the treatment tank can extend its service life.
[0003] Traditional water treatment systems often employ a single-tank design, making it difficult to simultaneously achieve impurity and oil removal. After purification, the incoming fluid is prone to generating bubbles that disrupt oil-water separation, while oil accumulation accelerates water deterioration, resulting in a short fluid lifespan. Existing technologies typically rely on external large-scale filtration equipment or chemical treatment, which suffers from high energy consumption, complex maintenance, and low water recycling rates. Utility Model Content
[0004] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a water filtration device.
[0005] The technical solution adopted in this utility model includes:
[0006] The treatment pool is divided into three sections along its length: a first section, a second section, and a third section.

[0008] The purification circulation system includes a circulation pump and a purification unit. The inlet end of the circulation pump is connected to the third section of the treatment tank, and its outlet end is connected to the water distribution mechanism. The purification unit is disposed on the flow path at the outlet end of the circulation pump.
[0009] An oil-water filtration system includes an oil-water collection unit located between the second section and the third section, and an oil-water treatment unit connected to the oil-water collection unit, wherein the outlet end of the oil-water treatment unit is connected to the purification circulation system.
[0010] The monitoring system includes temperature sensors and liquid level sensors located within the treatment tank.

[0012] As a preferred embodiment of the present invention, a partition plate is provided between the first section and the second section, and the partition plate is located at the bottom of the processing pool to separate the first section and the second section.
[0013] As a preferred embodiment of the present invention, the water distribution mechanism includes a plurality of spray pipes connected to the top of the treatment tank, wherein the spray pipes are arrayed with a plurality of spray heads or have a plurality of spray holes along their length.
[0014] As a preferred embodiment of the present invention, the purification unit includes a coarse filter and a fine filter located in the flow path between the circulating pump and the spray pipe.
[0015] As a preferred embodiment of this utility model, the bottom of the third section is provided with a fluid interface, which is connected to the inlet end of the circulating pump through a flexible pipeline, and a control valve is provided on the fluid interface.
[0016] As a preferred embodiment of the present invention, the oil-water collection unit includes an oil-water collection tank connected in the treatment tank, an oil-water collection pipe connected to one end of the oil-water collection tank, and the end of the oil-water collection pipe away from the oil-water collection tank connected to the inlet pipe of the circulating pump.

[0018] As a preferred embodiment of the present invention, the monitoring system further includes a control terminal located on the treatment pool, and the temperature detection element includes a temperature sensor located in the third section, the temperature sensor being electrically connected to the control terminal.

[0020] The beneficial effects of this utility model are as follows:
[0021] This utility model is a water filtration device. By setting up a purification circulation system, it can extract and purify the fluid in the second and third sections, and transport it to the first section through a water distribution mechanism to treat large scum, coarse oil particles and solid impurities in the treatment tank. By setting up an oil-water filtration system, it can efficiently collect and treat the floating oil mixture, and then perform deep separation through an oil-water treatment unit. The purified water is returned to the circulation system, which significantly extends the service life of the water.
[0022] By dividing the treatment tank into three sections, the functions of purified water cooling and oil separation are isolated. By setting up a bubble barrier in the first section, the bubbles generated during the spray cooling in the first section are restricted by the barrier, preventing them from spreading to the second and third sections and disrupting the accumulation of floating oil, thus ensuring the efficiency of oil-water separation.
[0023] The bottom-isolated partition design allows clean water to flow freely from the surface of the first section to the second section, while preventing backflow of sediment from the bottom of the second section, thus maintaining the water quality in the purification zone.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be 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 for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0035] The following is combined Figure 1-2 This invention describes a specific embodiment of a water filtration device, comprising:
[0036] Treatment tank 1 is divided into a first section 11, a second section 12 and a third section 13 along its length. The first section 11 is the flow zone for purified fluid, and the second section 12 and the third section 13 are used for the water passage zone after food processing. The zoned design corresponds to different stages of the water treatment process.
[0037] Water distribution mechanism 2 is located at the top of the first section 11. Water distribution mechanism 2 is used to distribute water...
[0038] After purification, the fluid is transported to the first section 11 by spraying, which can cool the fluid to a certain extent.
[0039] The purification and circulation system 3 includes a circulation pump 31 and a purification unit 32. The inlet end of the circulation pump 31 is connected to the third section 13 of the treatment tank 1, and its outlet end is connected to the water distribution mechanism 2. The purification unit 32 is disposed on the flow path at the outlet end of the circulation pump 31. The circulation pump 31 draws the fluid from the third section 13, and after the purification unit 32 removes residual suspended solids, grease, or other impurities, it is evenly returned to the first section 11 through the water distribution mechanism 2, and then flows sequentially into the second section 12 and the third section 13 to maintain or improve the water quality of the entire treatment tank 1, thereby extending the service life of the fluid in the treatment tank 1.
[0040] The oil-water filtration system 4 includes an oil-water collection unit 41 located between the second section 12 and the third section 13, and an oil-water treatment unit 42 connected to the oil-water collection unit 41. The outlet end of the oil-water treatment unit 42 is connected to the purification circulation system 3. When food passes through water in the second section 12, the floating oil and scum carried on the food are washed in the second section 12. The floating oil is guided to the oil-water collection unit 41 by the water flow and density difference. The collected oil-water mixture is transported to the oil-water treatment unit 42 for separation and purification. The treated water flows through the purification circulation system 3 through the inlet connected to the purification circulation system 3 to perform secondary treatment on the suspended solids, grease and other impurities in the fluid, thereby treating the floating oil and scum in the treatment tank 1, improving the cleanliness of the fluid in the second section 12 and the third section 13, and extending the service life of the fluid in the treatment tank 1. The first section 11 receives the purified fluid, and the third section 13 extracts the fluid. The treatment tank 1 forms a certain water flow direction from the first section 11 to the third section 13.
[0041] The monitoring system 5 includes a temperature detection device and a liquid level detection device 51 located in the treatment tank 1. The monitoring system 5 provides operating parameters, such as temperature detection for monitoring water temperature and liquid level detection for real-time monitoring of water level in the tank to prevent overflow, abnormal fluid circulation and other problems.
[0042] Please refer to Figure 1 As shown, the first section 11 is provided with a bubble barrier plate 111 connected to the treatment tank 1. The bubble barrier plate 111 is located on the side of the water distribution mechanism 2 near the second section 12. Since the purified fluid is transported to the first section 11 by spraying through the water distribution mechanism 2, the bubble barrier plate 111 is used to prevent the bubbles or water flow disturbances generated by the water distribution mechanism 2 from spreading to the second section 12. Since the fluid transported to the first section 11 is the purified fluid, the bubbles will disappear in a short time. By using the bubble barrier plate 111 to block the flow to the second to third sections 13, the bubbles are prevented from breaking up the oil droplets, hindering the formation of the oil layer, or even re-emulsifying the oil that has floated to the surface and bringing it into the water, which seriously reduces the oil-water separation efficiency. It should be noted that the bottom of the bubble barrier plate 111 is installed at a height not lower than the working liquid level in the treatment tank 1.
[0043] Please refer to Figures 1-2 As shown, a partition plate 112 is provided between the first section 11 and the second section 12. The partition plate 112 is located at the bottom of the treatment tank 1 to separate the first section 11 and the second section 12. The partition plate 112 can isolate the bottom of the first section 11 and the second section 12, preventing sediment at the bottom of the second section 12 from entering the first section 11, thus ensuring that the water quality in the first section 11 is relatively clean to a certain extent. The partition plate 112 can connect the top of the first section 11 and the second section 12, allowing water at the water surface and a certain depth below the water surface to flow relatively freely from the first section 11 to the second section 12. The fluid delivery of the water distribution mechanism 2 and the fluid spraying in the third section 13 can guide the flow of fluid, so as to realize the free flow of the relatively clean fluid in the first section 11 to the second and third sections 13.
[0044] Please refer to Figure 1 As shown, the water distribution mechanism 2 includes several spray pipes 21 connected to the top of the treatment tank 1. Several spray heads or spray holes are arranged in an array along the length of each spray pipe 21. Multiple spray pipes 21 cover the top of the treatment tank 1. The spray heads / holes on each spray pipe 21 are arranged in an array along the length to ensure that the water flow can evenly cover the entire surface of the first section 11. The spray heads / holes form a certain height with the liquid level of the fluid in the treatment tank 1. The fluid can be cooled to a certain extent when it is transported to the first section 11 by spraying. In addition, since different types of processed foods have different requirements for the temperature of the fluid in the treatment tank 1 after rinsing, and the cooling efficiency is low when the fluid is cooled by spraying, when the water distribution mechanism 2 cannot meet the cooling requirements of the temperature in the treatment tank 1, an external cooling device can be connected to cool the fluid in the treatment tank 1. The external cooling device is a conventional technology and will not be described in detail here.
[0045] Please refer to Figure 1 As shown, the purification unit 32 includes a coarse filter 321 and a fine filter 322 located in the flow path between the circulating pump 31 and the spray pipe 21. The coarse filter 321 and the fine filter 322 are used to remove particulate impurities from the circulating water, such as suspended solids, grease, or food impurities mixed in with the fluid. The coarse filter 321 handles larger impurity particles, protecting the fine filter from clogging by large particles and extending its lifespan. The fine filter 322 further removes fine suspended particles to ensure that the water returning to the water distribution mechanism 2 is sufficiently clean, avoiding nozzle clogging and improving the purification effect of the entire system. The coarse filter 321 and the fine filter 322 are existing conventional filters used to filter impurity particles in the treatment tank. The coarse filter 321 and the fine filter 322 correspond to different filter pore sizes to achieve graded filtration.
[0046] Please refer to Figures 1-2 As shown, a fluid interface 131 is provided at the bottom of the third section 13. The fluid interface 131 is connected to the inlet end of the circulating pump 31 through a flexible pipe 132, and a control valve 133 is provided on the fluid interface 131. The fluid interface 131 is located at the bottom of the third section 13, which can fully extract and purify suspended solids, grease or food impurities after sedimentation. The flexible pipe 132 allows for a certain displacement and vibration, which can reduce the stress on the pump and the interface. The control valve 133 can be used to adjust the circulation flow rate and cut off the water flow during maintenance.
[0047] Please refer to Figure 1 As shown, the oil-water collection unit 41 includes an oil-water collection tank 411 connected to the treatment tank 1. One end of the oil-water collection tank 411 is connected to an oil-water collection pipe 412, and the end of the oil-water collection pipe 412 away from the oil-water collection tank 411 is connected to the inlet pipe of the circulating pump 31. The oil-water collection tank 411 can block the floating oil layer. Since one end of the oil-water collection tank 411 is equipped with a collection pipe, the oil and water can be collected and transported to the oil-water treatment unit 42 for oil-water separation treatment. The separated fluid is then connected to the inlet pipe of the circulating pump 31 to obtain the power to extract and transport the oil and water in the second section 12 and the third section 13. Since the circulating pump 31 provides power to extract the oil-water mixture and the fluid in the third section 13 at the same time, the amount of oil-water mixture extracted is less than the amount of fluid extracted in the third section 13. A flow valve can be installed between the oil-water collection tank 411 and the oil-water treatment unit 42 as needed.
[0048] Please refer to Figure 1As shown, a multi-stage oil sludge filtration assembly is connected to the oil-water collection pipe 412. The multi-stage oil sludge filtration assembly includes a coarse oil sludge filter 421 and a fine oil sludge filter 422. The coarse oil sludge filter 421 is used to remove large sludge, coarse oil particles and solid impurities from the oil-water mixture. The fine oil sludge filter 422 further removes fine oil droplets, emulsified oil and fine suspended matter. In this embodiment, the coarse oil sludge filter 421 and the fine oil sludge filter 422 are oil-water treatment devices, which are existing conventional technologies. They only need to achieve oil-water separation and treatment and meet different graded treatment requirements, and are not specifically limited here.
[0049] Please refer to Figure 1 As shown, the monitoring system 5 also includes a control terminal located on the treatment tank 1. The temperature detection device includes a temperature sensor located in the third section 13. The temperature sensor is electrically connected to the control terminal. The control terminal is a monitoring and control system terminal, which can be a PLC or controller cabinet, etc. It is a conventional technology that receives signals from various sensors. For example, the temperature sensor placed in the third section 13 to measure the water temperature can determine the rationality of the water temperature acting on the food rinsing temperature by detecting the fluid temperature in the treatment tank 1.
[0050] Please refer to Figure 1 As shown, the liquid level detection element 51 is an ultrasonic liquid level gauge electrically connected to the control terminal. The control terminal is also used to receive the liquid level height information detected by the liquid level detection element 51 to ensure that the liquid level height in the treatment tank 1 is not lower than the lowest working position of the bubble barrier plate 111 and the oil-water collection tank 411, and at the same time, it must not exceed the preset maximum liquid level to prevent fluid overflow. The ultrasonic liquid level gauge is a non-contact measurement device installed above the water tank. It emits ultrasonic waves to the water surface and receives the echo to calculate the liquid level and monitor the fluid level. When there is an abnormality in the liquid level height, it can trigger the high and low liquid level alarm device to issue an alarm signal to prompt the staff to take appropriate action. The high and low liquid level alarm device is an existing conventional technical means and will not be described in detail here.
[0051] Working principle of this utility model:
[0052] In the water purification cycle, the fluid at the bottom of the third section 13 is drawn out by the circulation pump 31 and passes through the coarse filter 321 and the fine filter 322 in sequence to remove suspended impurities. After purification, it is sprayed to the first section 11 by the water distribution mechanism 2. The spraying process cools the water and forms a surface water flow that naturally overflows to the second section 12.
[0053] In the oil-water separation process, when food passes through water in the second section 12, the grease and scum float to the surface and accumulate. The water flow pushes the floating oil into the oil-water collection tank 411. The mixture is transported through the collection pipe to the oil-scum coarse filter 421 and the oil-scum fine filter 422. After pretreatment, it enters the oil-water treatment unit 42 for deep separation. The separated purified water is connected to the inlet of the circulation pump 31 and re-participates in the purification cycle.
[0054] In the first section 11, the purified fluid generates bubbles under the action of spraying. The bubbles generated by spraying are restricted in the first section 11 by the bubble blocking plate 111 to avoid interfering with the formation of the oil layer in the second and third sections. The bubbles disappear within a certain period of time after being blocked by the bubble blocking plate 111.
[0055] The bottom baffle of the treatment tank 1 prevents the sediment in the second section 12 from entering the first section 11, ensuring that the first section 11 remains relatively clean;
[0056] The temperature sensor in the detection system monitors the water temperature in the third section 13, and the level gauge provides real-time feedback on the water level. The data is uploaded to the control terminal. If the water temperature exceeds the standard, the external cooling equipment can be activated. An alarm is triggered when the water level is abnormal to prevent overflow or pump dry running.
[0057] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0058] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims of this application, they should all fall within the protection scope of this utility model.
