[0033] Currently, filtration devices are widely used for solid-liquid separation in fields such as mineral processing, chemical engineering, and environmental protection, especially for filtering materials such as slurries and suspensions. Traditional filtration devices typically employ vacuum filtration or pressure filtration, but several technical drawbacks remain in practical applications. For example, traditional filtration devices rely on vacuum pumps to generate negative pressure, but vacuum pumps themselves suffer from high energy consumption, complex maintenance, and high costs, undoubtedly increasing the manufacturing cost and maintenance difficulty of the filtration device. Furthermore, existing filtration devices must maintain a completely sealed system to ensure negative pressure during operation. This pressure releases when cleaning the filtrate and sludge, causing the entire filtration process to stop, preventing continuous operation and severely impacting filtration efficiency, thus hindering efficient solid-liquid separation.

[0034] In view of the above situation, referring to Figure 1 A preferred embodiment of this application provides a hydrodynamic continuous centralized filtration device, including a filtration system, a circulating water system, and a circulating water purification buffer device, wherein:

[0035] The circulating water system includes a circulating water pump 1, circulating water pipes (304 stainless steel), and a water tank 9 with an overflow outlet (2m³ capacity). 3 The water tank 9 is connected to the input end of the circulating water pump 1 via a circulating water pipe;

[0036] The circulating water purification and buffer device is connected to the output end of the circulating water pump 1 at one end and to the water tank 9 at the other end. It is used to buffer and purify the output of the circulating water pump 1 and discharge the sediment.

[0037] The filtration system includes multiple filter pipes and a suction flask 2. One end of each filter pipe is connected in parallel to the circulating water pipe between the circulating water pump 1 and the water tank 9 via a second valve 5. The other end of each filter pipe is connected to a Buchner funnel 4. Each filter pipe is also detachably connected to the suction flask 2 via a first valve 3 and a detachable connector connected in sequence between the Buchner funnel 4 and the second valve 5. In this embodiment, the filtration system includes five filter pipes and one suction flask 2. Each filter pipe has a Buchner funnel 4 connected to its upper end, for a total of five Buchner funnels 4. In specific implementation, the number of filter pipes and Buchner funnels 4 can be increased or decreased according to actual needs to meet the centralized suction filtration requirements of different circulating water purification methods.

[0038] This embodiment provides a hydrodynamic continuous centralized filtration device, including a filtration system, a circulating water system, and a circulating water purification and buffer device. The circulating water system includes a circulating water pump, circulating water pipes, and a water tank 9 with an overflow outlet. The water tank is connected to the input end of the circulating water pump via the circulating water pipes. The circulating water purification and buffer device is connected at one end to the output end of the circulating water pump and at the other end to the water tank, used to buffer and purify the output of the circulating water pump and discharge sediment. The filtration system includes multiple filter pipes and a filtration bottle. One end of each filter pipe is connected in parallel to the circulating water pipe between the circulating water pump and the water tank via a second valve. The other end of each filter pipe is connected to a Buchner funnel. Each filter pipe is also detachably connected to the filtration bottle between the Buchner funnel and the second valve via a first valve and a detachable connector connected in sequence. Through the above configuration, this embodiment solves several problems existing in current filtration devices and has the following technical effects:

[0039] 1. Through the optimized design of the structure, this embodiment can drive the circulating water system with only an ordinary circulating water pump, spontaneously forming a stable negative pressure at the filtration end to achieve an equivalent vacuum filtration effect, thereby reducing energy consumption and usage and maintenance costs.

[0040] 2. This embodiment is an open system, not a closed system. It can realize online solid-liquid separation in the filtrate during operation, and automatically discharge the sludge and filtrate liquid through overflow when the machine is on. Since the system does not need to release negative pressure when cleaning the filtrate and sludge, it will not cause the entire filtration operation to stop, thus realizing continuous operation.

[0041] 3. This embodiment integrates a circulating water purification system to separate and collect solid impurities in the water in real time, ensuring the cleanliness of the circulating water, avoiding pipe blockage and equipment wear and tear. The circulating water purification buffer device buffers and purifies the output of the circulating water pump and discharges the sediment to achieve rapid settling of solid sediment. The circulating water purification buffer device prevents the settled particles from being stirred up again by the upflow, and can further reduce the water flow velocity to achieve rapid settling of solid sediment.

[0042] 4. This embodiment achieves water reuse and reduces water replenishment by forming a closed-loop water circulation system (water tank overflow outlet balances water volume) and a circulating water purification buffer device, while preventing slurry leakage, thus meeting environmental protection requirements.

[0043] In a preferred embodiment of this application, the circulating water pump 1 is a centrifugal water pump.

[0044] In this embodiment, the circulating water pump 1 is a centrifugal water pump. In this embodiment, only an ordinary centrifugal water pump is used as the circulating water pump 1 to drive the circulating water system. Compared with the existing technology that uses a vacuum pump to generate negative pressure, which has problems such as high energy consumption, complex maintenance and high cost, the centrifugal water pump is cheap, easy to maintain, durable and reliable, and has low energy consumption. It can spontaneously form a stable negative pressure at the filter end to achieve an equivalent vacuum filtration effect, thereby greatly reducing energy consumption and usage and maintenance costs. Of course, other cheap, easy to maintain, durable and reliable, and low energy-consuming circulating water pumps 1 can also be selected, such as peristaltic pumps, axial flow pumps, etc., which will not be listed here. Those skilled in the art can make corresponding selections according to actual working conditions and cost requirements, which will not be elaborated here.

[0045] In a preferred embodiment of this application, the detachable connector is a quick connector. When it is necessary to switch the filtrate collection to connect one of the filter pipes to the filtration bottle 2, it can be quickly connected to the filtration bottle 2 by simple manual operation through the quick connector. This facilitates the connection of the filtration bottle 2 and enables quick switching of filtrate collection, thereby greatly improving work efficiency and applicability.

[0046] In a preferred embodiment of this application, a check valve 6 is also provided on the filter pipe between the second valve 5 and the circulating water pipe.

[0047] In this embodiment, a check valve 6 is also provided on the filter pipe between the second valve 5 and the circulating water pipe. The check valve 6 can prevent water in the circulating water pipe from flowing back into the filter pipe from bottom to top during operation, thus ensuring the filtration effect.

[0048] In a preferred embodiment of this application, the circulating water purification and buffering device includes a primary purification and buffering device and a secondary purification and buffering device connected in sequence through pipelines, which are used to buffer and purify the output of the circulating water pump 1 in two stages to discharge sediment and silt.

[0049] The circulating water purification and buffering device in this embodiment includes a primary purification and buffering device and a secondary purification and buffering device connected in sequence through pipelines. It is used to buffer and purify the output of the circulating water pump 1 in two stages to discharge sediment. Compared with a single-stage purification and buffering device that performs a single-stage buffering and purification to discharge sediment, this embodiment uses a primary and secondary purification and buffering device to perform a two-stage buffering and purification to discharge sediment, which can buffer and purify more sediment, thereby effectively improving the filtration effect and achieving a better purification purpose.

[0050] In a preferred embodiment of this application, the primary purification buffer device includes a buffer tank 7. The buffer tank 7 has a relatively large height-to-diameter ratio, preferably above 2:1. A baffle plate is provided in the middle of the buffer tank 7 to buffer and decelerate the output of the circulating water pump 1 and form a flow deflector. An overflow port connected to the secondary purification buffer device is provided on one side of the buffer tank 7 via a pipeline. Thus, the appropriate height-to-diameter ratio and the baffle plate work together to ensure that the output of the circulating water pump 1 has both a buffered and reduced flow velocity and a sufficiently long flow path within the buffer tank 7. This allows the output of the circulating water pump 1 to remain in the buffer tank 7 for a sufficient time. Sufficient residence time and flow velocity buffering provide more time for buffering, purification, and sedimentation, allowing for the removal of more sediment and effectively improving the filtration effect to achieve a better purification purpose.

[0051] In a preferred embodiment of this application, the bottom of the buffer tank 7 is further provided with a first sludge discharge valve 71 for discharging deposited sludge. When a certain amount of sludge accumulates at the bottom of the buffer tank 7, opening the first sludge discharge valve 71 can discharge the sludge from the bottom of the buffer tank 7. In addition, the first sludge discharge valve 71 can be a pneumatic sludge discharge valve or a hydraulic sludge discharge valve, and the valve closure can be controlled by a pneumatic system or a hydraulic system, which greatly reduces the labor intensity of operators and improves the automation level of the device.

[0052] In a preferred embodiment of this application, the secondary purification buffer device includes a purification device 8, which is a conical funnel structure (upper diameter Φ800mm, lower outlet Φ150mm, cone angle about 55°). The upper part is respectively provided with left and right inclined baffles (304 stainless steel, thickness 3mm) inclined at a set angle. An overflow port connected to a water tank 9 through a pipeline is provided on one side of the purification device 8.

[0053] The purification device 8 in this embodiment has a conical funnel structure. The conical funnel structure can suppress liquid disturbance. The wider cross-section at the top reduces the fluid velocity and reduces the interference of turbulence on sedimentation. The narrow diameter at the bottom can prevent settled particles from being stirred up again by the rising flow. At the same time, a baffle with a certain angle is designed at the top of the purification device to further reduce the water flow velocity and achieve rapid sedimentation of solid sediment. The filtered water flows into the water tank 9 through the overflow port set on one side of the purification device 8 and the settled particles sink to the bottom of the conical funnel structure purification device 8 under the action of gravity, thus achieving purification buffering.

[0054] In a preferred embodiment of this application, the set angle is 10° to 20°, with 15° being particularly suitable.

[0055] In this embodiment, the tilt angle of the left and right tilting baffles is 10° to 20°, and more preferably 15°. At this angle, the water flow velocity can be further reduced to achieve rapid settling of solid sediment, while also taking into account the work efficiency. If the angle is too small, although the water flow velocity can be reduced, it will affect the work efficiency of the purification buffer. If the angle is too large, although the work efficiency of the purification buffer can be improved, the rapid settling effect of solid sediment will be reduced due to the failure to properly reduce the water flow velocity, resulting in the final purification effect. Setting the angle to 15° can well balance the purification efficiency and purification effect.

[0056] In a preferred embodiment of this application, a second sludge discharge valve 81 for discharging deposited sludge is provided at the bottom of the purification device 8. When a certain amount of sludge has accumulated at the bottom of the purification device 8, opening the second sludge discharge valve 81 can discharge the sludge from the bottom of the buffer tank 7. In addition, the second sludge discharge valve 81 can be a pneumatic sludge discharge valve or a hydraulic sludge discharge valve, and the valve can be closed by a pneumatic or hydraulic system, which greatly reduces the labor intensity of operators and improves the automation level of the device.

[0057] The working principle of the filtration device provided in the above embodiments is as follows:

[0058] One end of the centrifugal water pump is connected to the circulating water tank 9, and the other end is connected to the circulating water buffer and purification device. During operation, it drives the water entering the circulating water pipe from the filter pipe and the water tank 9 to circulate. The pipe is full of water, and the high-speed water flow generates negative pressure to achieve solid-liquid separation. The filtrate enters the collection system through the circulating water pipe, enabling continuous operation.

[0059] Before entering water tank 9, the circulating water first passes through a circulating water purification and buffering device. This device purifies the circulating water in two stages: a primary purification and buffering device and a secondary purification and buffering device. Due to the conical funnel structure and baffle action, the water flow velocity is reduced, particles settle, and silt is deposited and purified. The purified water returns to water tank 9, while silt is periodically discharged through the first sludge discharge valve 71 at the bottom of buffer tank 7 and the second sludge discharge valve 81 of purification device 8, ensuring water cleanliness. Water tank 9 is equipped with an overflow port, allowing water to overflow when the tank is full.

[0060] The hydrodynamic continuous centralized filtration device provided in this application can be widely used in mineral processing, chemical industry, environmental protection and other fields for solid-liquid separation, especially for filtering materials such as slurries and suspensions. The filtered water can not only be recycled, but also provides a driving force for filtration. Compared with traditional filtration devices, this application reduces energy consumption, maintenance complexity and cost. Furthermore, since the equipment does not require maintaining a completely sealed system to ensure negative pressure during operation, the system does not need to release negative pressure when cleaning filtrate and sludge, thus preventing the entire filtration operation from stopping and enabling continuous operation, significantly improving operational efficiency.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
