Description

Technical Field

[0001] This utility model relates to the field of filtration, specifically to a central water outlet system. Background Technology

[0002] Filtration devices, as crucial separation equipment, play an indispensable role in numerous industries. In industrial production, industries such as chemical, pharmaceutical, and food processing rely on filtration devices to separate impurities and particulate matter from liquids or gases to ensure product purity and quality. For example, in processing, cutting fluid is often used for lubrication and cooling. However, this cutting fluid carries debris into recovery devices; therefore, filtration devices are needed to remove suspended solids and impurities from the liquid, enabling the treated liquid to meet the requirements for recycling.

[0003] In practical applications, existing filtration devices are typically selected and used based on different filter media and filtration requirements. In liquid filtration, existing filtration devices mainly consist of a filter container, filter media, inlet and outlet pipes, support structure, and backwashing or cleaning system, thereby filtering the liquid for subsequent recycling.

[0004] However, although existing filtration devices can perform basic filtration functions, they still have certain shortcomings: some existing filtration devices have relatively simple filtration structures, resulting in poor filtration effects during the filtration process and insufficient filtration of liquids, thus reducing the overall filtration effect and efficiency. Secondly, the poor filtration effect of the filter media and its tendency to clog affect the fluid flow rate and filtration effect, leading to longer filtration cycles and reduced production efficiency. In addition, existing filtration devices generally rely on a simple primary filtration process using a filter screen, resulting in poor reliability and stability of the liquid filtration effect. The filter screen is also prone to clogging, affecting its long-term durability and service life. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies by providing a central water outlet system. This system solves the technical problems in the prior art where the existing filtration devices have a relatively simple filtration structure, resulting in poor filtration effect, low filtration reliability and stability, and consequently affecting the filtration cycle and production efficiency.

[0006] The objective of this utility model is achieved through the following means:

[0007] A central water outlet system includes a housing and a filter assembly mounted on the housing. An electrical control box is installed on the housing. The interior of the housing is divided into a first sedimentation chamber and a second sedimentation chamber, which are interconnected by baffles. The filter assembly includes a filter barrel mounted on the housing by a stand. Inside the filter barrel, a filter chamber and a drain chamber are formed by partitions. An inlet and an outlet, respectively communicating with the filter chamber and drain chamber, are located outside the filter barrel. The inlet is tangential to the filter barrel and passes through it to communicate with the filter chamber. A second drain pipe, communicating with the filter chamber, is connected to the bottom of the filter barrel via a second drain valve. Filter bags are detachably connected to the partitions via connectors. A drain pipe, communicating with the drain chamber, is located outside the filter barrel. One end of the drain pipe passes through the housing and communicates with the first sedimentation chamber. A high-pressure pump is installed on the housing, connected to a filter cartridge. One end of the filter cartridge passes through the housing and extends into the second sedimentation chamber. The high-pressure pump has a high-pressure water outlet, which is connected to a return pipe communicating with the first sedimentation chamber.

[0008] Furthermore, as described above, the baffle includes a first baffle and a second baffle, which are vertically installed inside the housing, and a flow channel is provided between the first baffle and the second baffle.

[0009] The second sedimentation chamber is formed by extending the interval of the first sedimentation chamber through a double baffle structure. The flow channel realizes the flow path of the liquid, so that after the liquid passes through the first sedimentation chamber for sedimentation, it enters the second sedimentation chamber for secondary sedimentation and filtration, thereby improving the sedimentation efficiency of impurities and enhancing the initial solid-liquid separation effect.

[0010] Furthermore, as described above, the filtration assembly also includes a vortex filter. A mounting bracket for installing the vortex filter is provided on the side of the filter housing. The vortex filter has a liquid guide port and a first drain valve for discharging wastewater. A first drain pipe is connected to the first drain valve. The vortex filter is connected to an inlet valve through the liquid guide port. An inlet pipe is connected to the vortex filter through the drain port. The inlet pipe communicates with the inlet port. The end of the first drain pipe furthest from the vortex filter extends towards the first sedimentation chamber, thus communicating with the first sedimentation chamber.

[0011] Vortex filters pre-separate large particles of impurities from liquids through centrifugal force, reducing the load on subsequent filtration components; they also reduce the accumulation of dirt in the filter canister, lowering the risk of filter bag clogging, while reducing the frequency of manual cleaning and improving the continuous operation capability of the filtration system.

[0012] Optionally, in some embodiments, the first drain pipe is connected to an external collection tank through an overflow port to prevent contamination of the liquid filtered and separated from the drain pipe in the first sedimentation chamber.

[0013] The sediment at the bottom of the filter chamber is directly discharged through the second drain pipe, realizing the directional discharge of waste after solid-liquid separation, preventing the sediment from accumulating in the filter barrel and reducing the filtration area; and preventing it from entering the first sedimentation chamber, enhancing the centralized sedimentation treatment of filtered waste and reducing the maintenance cost of the filtration system.

[0014] Optionally, in some embodiments, a second drain pipe is connected to an external collection tank, allowing the liquid discharged from the drain pipe to enter the collection tank. This prevents the liquid filtered and separated by the drain pipe from entering the first sedimentation chamber, reduces the accumulation of dirt in the filter bucket, and lowers the risk of filter bag clogging.

[0015] Furthermore, as described above, the partition plate is provided with a connection hole, through which the connector passes and is hung and installed on the partition plate. The connector includes a fitted shaping bracket and a support frame. The filter bag is fitted over the shaping bracket, the shaping bracket is detachably inserted into the support frame, and a gap is provided between the shaping bracket and the support frame.

[0016] The gap design between the fixed bracket and the support frame ensures that the filter bag fully expands, maintaining the maximum filtration area; the detachable connection method facilitates quick replacement of the filter bag, avoiding the decrease in filtration efficiency caused by filter media blockage; the hanging installation structure simplifies the disassembly and assembly process, shortening equipment downtime for maintenance.

[0017] Furthermore, as described above, a support flange is formed on the support frame, a sealing ring is connected to the bottom of the support flange, a groove matching the sealing ring is provided on the partition plate, and one end of the support frame passes through the connecting hole and contacts the partition plate through the support flange.

[0018] The sealing ring and groove fit together to form a reliable seal, preventing unfiltered liquid from bypassing the filter bag and directly entering the drain chamber, thus ensuring filtration reliability. The support flange provides uniform support force, preventing the filter bag from deforming or breaking due to uneven local stress, and extending the service life of the filter media.

[0019] Furthermore, as described above, the shaping bracket contacts the supporting flange via a shaping flange, and a compression spring is connected to the shaping flange via a hanger. A bucket lid is paired with the filter bucket, and the end of the compression spring away from the hanger contacts the inner wall of the bucket lid.

[0020] The compression spring applies pressure to the shaped bracket through the shaped flange, ensuring that the filter bag is always placed in the filter chamber, preventing it from floating or falling off due to liquid impact during filtration, improving the reliability and stability of the filter bag installation through the connector, and thus ensuring the filtration effect.

[0021] Furthermore, as described above, the side of the filter bucket is connected to a blockage detection alarm for detecting filter chamber blockage, and the top of the bucket lid is equipped with a backflush cleaning valve.

[0022] The backflush cleaning valve can periodically perform reverse pulse cleaning on the filter bags, removing attached impurities, restoring filtration capacity, and significantly extending the filter bag replacement cycle.

[0023] In some embodiments, the filter canister has a backflushing function. If the filter bag is clogged, after the clogging detection alarm is activated, compressed air can be connected through the backflushing cleaning valve to automatically clean the filter screen and connecting parts inside the filter canister, thereby improving the durability and service life of the filtration device.

[0024] Furthermore, as described above, the housing is equipped with a level detector for detecting the liquid level in the second sedimentation chamber, and the side of the housing is provided with an overflow port that communicates with the first sedimentation chamber.

[0025] The liquid level detector monitors the liquid level in the second sedimentation chamber in real time to prevent liquid overflow due to excessive liquid intake; the overflow port serves as a safety redundancy, automatically discharging excess liquid when the liquid level is abnormal, providing double protection to avoid the risk of liquid leakage and improve the safety of equipment operation.

[0026] Furthermore, as described above, the return pipe is connected to a pressure regulating valve and a pressure gauge.

[0027] The pressure regulating valve precisely controls the outlet water pressure of the high-pressure pump, adapting to different operating conditions. The pressure gauge provides visual pressure monitoring, facilitating timely adjustment of system parameters, ensuring stable operation of the filtration system within the optimal pressure range, and extending the service life of the equipment.

[0028] Optionally, in some embodiments, the pressure regulating valve is equipped with an overflow valve, which can generate overflow pressure relief when the pressure is too high, ensuring the reliability and safety of high-pressure water discharged from the high-pressure water outlet.

[0029] The beneficial effects of this utility model are as follows: By tangentially setting the inlet to the filter chamber, the liquid flows downward in a spiral motion along the inner wall of the filter chamber. The spiral flow of the liquid along the inner wall of the filter chamber generates centrifugal force, completing the vortex centrifugal filtration of the liquid, reducing the phenomenon of filter clogging. Impurities in the liquid settle into the interior of the filter chamber and are discharged through the second drain valve along the second drain pipe. At the same time, the filter screen filters impurities in the liquid. When the liquid level reaches the outlet, the liquid enters the first sedimentation chamber along the drain pipe for a first sedimentation, that is, a second filtration and sedimentation of impurities in the liquid. The filtered liquid spreads into the second sedimentation chamber for a second sedimentation, thus completing the filtration and sedimentation of the liquid, thereby ensuring the reliability and stability of filtration and improving the filtration effect and stability of the liquid.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0042] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.

[0043] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] In this embodiment, refer to Figures 1-8 The specific implementation of the central water outlet system includes a housing 100 and a filter assembly 200 mounted on the housing 100. An electrical control box 3 is mounted on the housing 100. The interior of the housing 100 is divided into a first sedimentation chamber 101 and a second sedimentation chamber 102, which are interconnected by baffles. The filter assembly 200 includes a filter barrel 201 and a vortex filter 202. The filter barrel 201 is mounted on the housing 100 by a stand. A mounting bracket 1 is used to mount the vortex filter 202 on the side of the filter barrel 201. The filter barrel 201 is divided into a filter chamber 2011 and a drain chamber 2012 by partitions 2. The filter barrel 201 has an inlet 2013 and an outlet 2014, which are respectively connected to the filter chamber 2011 and the drain chamber 2012. The inlet 2013 is connected to the vortex filter 202 via an inlet pipe 4, and the inlet 2013 is connected to the filter barrel 201. The vortex filter 202 is tangentially arranged and passes through the filter barrel and communicates with the filter chamber. It is equipped with a liquid guide port 2021 and a first drain valve 2023 for sewage discharge. The first drain valve 2023 is connected to a first drain pipe 5. The bottom of the filter barrel 201 is connected to a second drain pipe 7 that communicates with the filter chamber 2011 through a second drain valve 6. The partition 2 is connected to a filter bag 203 through a connector. The filter barrel 201 is equipped with a drain pipe 8 that communicates with the drain chamber 2012. One end of the drain pipe 8 passes through the box body 100 and communicates with the first sedimentation chamber 101. The box body 100 is equipped with a high-pressure pump 9. The high-pressure pump 9 is connected to a filter cartridge 10. One end of the filter cartridge 10 passes through the box body 100 and extends to the second sedimentation chamber 102. The high-pressure pump 9 is equipped with a high-pressure water outlet 11. The high-pressure water outlet 11 is connected to a return pipe 12 that communicates with the first sedimentation chamber 101.

[0045] In the specific implementation process, the vortex filter 202 is connected to the liquid inlet 2021. It uses the vortex separation principle to pre-treat the liquid entering the filter tank 201. This structure can separate large particulate impurities in the liquid by centrifugal force before filtration, and realize the directional discharge of impurities through the first drain valve 2023 and the first drain pipe 5. This avoids large particulate impurities from directly entering the filter tank 201 and causing rapid clogging of the filter bag 203, which significantly improves the anti-pollution ability and operational stability of the filtration system. At the same time, the liquid that has been pre-filtered by the vortex filter 202 can further improve the filtration efficiency and effect in subsequent filtration.

[0046] The liquid undergoes a series of filtration processes, including first filtration, second filtration, first sedimentation, and second sedimentation, through the vortex filter 202, filter barrel 201, first sedimentation chamber 101, and second sedimentation chamber 102. This ensures the reliability and stability of the filtration process and improves the filtration effect of the liquid.

[0047] Reference Figure 3 and Figure 4 The baffle includes a first baffle 13 and a second baffle 14, which are vertically installed inside the housing 100, and a flow channel 15 is provided between the first baffle 13 and the second baffle 14.

[0048] The second sedimentation chamber 102 is formed by extending the interval of the first sedimentation chamber 101 through the double baffle structure. The flow channel 15 realizes the flow path of the liquid, so that the liquid enters the second sedimentation chamber 102 for secondary sedimentation and filtration after sedimentation in the first sedimentation chamber 101, thereby improving the sedimentation efficiency of impurities and enhancing the initial solid-liquid separation effect.

[0049] The vortex filter 202 is connected to the inlet pipe 4 via the drain port 2022. The end of the first sewage pipe 5 away from the vortex filter 202 extends into the first sedimentation chamber 101, so that the first sewage pipe 5 is connected to the first sedimentation chamber.

[0050] The vortex filter 202 pre-separates large particulate impurities from the liquid through centrifugal action, reducing the load on the subsequent filter components 200; it also reduces the accumulation of dirt in the filter canister 201, lowers the risk of clogging of the filter bag 203, reduces the frequency of manual cleaning, and improves the continuous operation capability of the filtration system.

[0051] Reference Figure 3 and Figure 4 In the specific implementation process, the first sewage pipe 5 is inserted into the first sedimentation chamber and connected to the overflow port to prevent the liquid filtered and separated by the sewage pipe 8 in the first sedimentation chamber 101 from being contaminated.

[0052] In practice, the liquid carrying impurities in the filter bucket 201 can be diverted to an external collection tank for centralized secondary treatment via the second sewage pipe 7, reducing the accumulation of impurities in the filter bucket 201 and lowering the risk of clogging of the filter bag 203. Simultaneously, the liquid discharged from the sewage pipe enters the collection tank, preventing it from entering the first sedimentation chamber 101 and contaminating the liquid filtered and separated by the drain pipe 8.

[0053] The sediment at the bottom of the filter chamber 2011 is directly discharged through the second drain pipe 7, realizing the directional discharge of waste after solid-liquid separation, preventing the sediment from accumulating in the filter bucket 201 and reducing the filtration area, thus reducing the maintenance cost of the filtration system.

[0054] Reference Figures 5-7 The partition 2 has a connection hole 16. The connector passes through the connection hole 16 and is hung and installed on the partition 2. The connector includes a shaping bracket 17 and a support frame 18. The filter bag 203 is sleeved on the outside of the shaping bracket 17. The shaping bracket 17 is detachably inserted into the support frame 18, and there is a gap between the shaping bracket 17 and the support frame 18.

[0055] The gap design between the fixed bracket 17 and the support frame 18 ensures that the filter bag 203 is fully expanded, maintaining the maximum filtration area; the detachable connection method facilitates quick replacement of the filter bag 203, avoiding the decrease in filtration efficiency caused by filter media blockage; the hanging installation structure simplifies the disassembly and assembly process, shortening equipment downtime for maintenance.

[0056] Reference Figure 7 The support frame 18 has a support flange, and a sealing ring is connected to the bottom of the support flange. The partition plate 2 has a groove that matches the sealing ring. One end of the support frame 18 passes through the connection hole 16 and contacts the partition plate 2 through the support flange.

[0057] The sealing ring and groove fit together to form a reliable seal, preventing unfiltered liquid from bypassing the filter bag 203 and directly entering the drain chamber 2012, thus ensuring filtration reliability. The support flange provides uniform support force, preventing the filter bag 203 from deforming or breaking due to uneven local stress, and extending the service life of the filter media.

[0058] The shaping bracket 17 contacts the support flange via a shaping flange. A compression spring 20 is connected to the shaping flange via a hanger 19. A bucket lid is paired on the filter bucket 201. The end of the compression spring 20 away from the hanger 19 contacts the inner wall of the bucket lid.

[0059] The compression spring 20 applies pressure to the shaped bracket 17 through the shaped flange and ensures that the filter bag 203 is always placed in the filter chamber 2011, preventing it from floating or falling off due to liquid impact during the filtration process, improving the reliability and stability of the connection for installing the filter bag 203, thereby ensuring the filtration effect.

[0060] The filter bucket 201 is connected to a blockage detection alarm 21 for detecting blockage of the filter chamber 2011 on its side, and a backflush cleaning valve 22 is provided on the top of the bucket lid.

[0061] The backflush cleaning valve 22 can periodically perform reverse pulse cleaning on the filter bag 203, remove attached impurities, restore filtration capacity, and significantly extend the replacement cycle of the filter bag 203.

[0062] In some embodiments, the filter canister 201 has a back-flushing function. If the filter bag 203 is clogged, after the clogging detection alarm 21 is activated, compressed air can be connected through the back-flushing cleaning valve 22 to automatically clean the filter screen and connectors inside the filter canister 201, thereby improving the durability and service life of the filtration device.

[0063] The housing 100 is equipped with a level detector 23 for detecting the liquid level in the second sedimentation chamber 102, and the side of the housing 100 is provided with an overflow port 24 that communicates with the first sedimentation chamber 101.

[0064] The liquid level detector 23 monitors the liquid level in the second sedimentation chamber 102 in real time to prevent liquid overflow due to excessive liquid intake; the overflow port 24 serves as a safety redundancy and automatically discharges excess liquid when the liquid level is abnormal, providing double protection to avoid the risk of liquid leakage and improve the safety of equipment operation.

[0065] The return pipe 12 is connected to a pressure regulating valve 25 and a pressure gauge 26.

[0066] The pressure regulating valve 25 precisely controls the outlet water pressure of the high-pressure pump 9 to adapt to different working conditions. The pressure gauge 26 provides visual pressure monitoring, which facilitates timely adjustment of system parameters, ensuring that the filtration system operates stably within the optimal pressure range and extending the service life of the equipment.

[0067] Optionally, in some embodiments, the pressure regulating valve 25 is provided with an overflow valve, which can generate overflow pressure relief when the pressure is too high, ensuring the reliability and safety of high-pressure water discharge from the high-pressure water outlet 11.

[0068] The specific filtering process in this embodiment is as follows:

[0069] Primary filtration: Connect the liquid inlet 2021 to the external machine tool cutting fluid discharge device so that the cutting fluid used for cutting enters the vortex filter 202 through the liquid inlet 2021. The liquid entering the filter tank 201 is pretreated by using the vortex separation principle. This structure can separate large particulate impurities in the liquid by centrifugal force before filtration, so that the debris in the cutting fluid is deposited at the first drain valve 2023.

[0070] Secondary filtration: The liquid filtered in the first stage is introduced into the filter chamber 2011 through the inlet pipe 4 and inlet 2013. When the liquid enters the filter chamber 2011 at high speed, the inlet 2013 is tangentially set with the filter barrel 201, which causes the liquid to flow along the inner wall of the filter chamber 2011 and generate centrifugal force. Impurities in the liquid settle into the interior of the filter chamber 2011. The liquid is then filtered a second time using a filter screen to reduce the amount of impurities in the liquid rising into the drain chamber 2012.

[0071] Primary sedimentation: The drain pipe 8 connects the drain chamber 2012 and the first sedimentation chamber 101. When the liquid level in the filter tank 201 rises and enters the drain chamber 2012, the liquid filtered in the second stage is introduced into the first sedimentation chamber 101 through the drain pipe 8, so that the liquid enters the first sedimentation chamber 101 for sedimentation and filtration again, that is, the third filtration to settle the impurities in the liquid, thereby ensuring the stability and reliability of filtration.

[0072] Secondary sedimentation: A first sedimentation chamber 101 and a second sedimentation chamber 102 are formed by the gap between the first baffle 13 and the second baffle 14, so that the liquid after the first sedimentation can pass through the flow channel 15 into the second sedimentation chamber 102 for secondary sedimentation, that is, to complete the fourth filtration and sedimentation of the liquid, thereby ensuring the reliability and stability of filtration and improving the filtration effect of the liquid. The filtered liquid is driven by the high-pressure pump 9 to be discharged from the high-pressure water outlet 11, and it can be recycled through the connection of the return pipe 12.

[0073] In summary, the system employs a vortex filter 202 for primary filtration, a filter barrel 201 for secondary filtration, a first sedimentation chamber 101 for primary sedimentation and tertiary filtration, and a second sedimentation chamber 102 for secondary sedimentation and quaternary filtration. This ensures the reliability and stability of the filtration process and improves the filtration effect of the liquid.
