Description

Technical Field

[0001] This invention relates to the field of tubular filtration equipment technology, specifically to a tubular volume reduction filtration device with fluid turbulence. Background Technology

[0002] In traditional wastewater pretreatment processes, inorganic / organic flocculants are commonly added to cause suspended solids in the wastewater to settle (float) and separate from the water, achieving the purpose of volume reduction. However, this introduces chemical agents, causing secondary pollution of the effluent. Tubular filters are mainly used to remove small amounts of particulate matter from liquids and suspended particles, oil, and dust from compressed air. They can be used to protect compressors, pumps, instruments, and other equipment, ensuring their normal operation and extending their service life.

[0003] Existing tubular volume reduction filtration devices can reduce wastewater volume without using flocculants by arranging backwash pipes on the outside of the filter media; however, simple backwash pipes are not effective at removing filter cake from the filter media, resulting in a short cycle of downtime for cleaning the filter media.

[0004] For example, the aforementioned problem exists in patent (CN222677442U); it describes "a tubular reduction filtration device, wherein the raw water inlet pipe is connected in a sealed manner to the inlet and outlet pipes of the first filtration unit through an inlet flow meter and a pressure gauge; the outlet pipe of the first filtration unit is connected in series with the following filtration units in a sealed manner; the outlet pipe of the last filtration unit is connected in a sealed manner to the concentrate pipe through a concentrate flow meter; a backwash port is installed on the filter tube wall of each filtration unit; the backwash pipes are connected in parallel in a sealed manner through the backwash ports of each filtration unit; and a clean water outlet is installed below the filter tube wall of the filtration unit, for the clean water..." The discharge pipes are connected in parallel and sealed to the clean water discharge pipe via a clean water flow meter. The advantages are: wastewater can be reduced in volume without the use of flocculants; it solves the problem of other filtration systems not being able to operate continuously, eliminating the need for a gradual decrease in filtration flow and subsequent shutdown for cleaning the filter media, unlike filter presses and other filters. The tubular volume reduction filtration device in the aforementioned patent uses a backwash pipe arranged outside the filter media to backwash and peel the filter cake at a fixed position. However, the simple backwash pipe is not very effective at peeling the filter cake from the filter media, resulting in a short cycle of shutdown for cleaning the filter media.

[0005] To address the aforementioned tubular volume reduction filtration devices, wastewater volume can be reduced without the use of flocculants by arranging backwash pipes on the outside of the filter media. However, simple backwash pipes are not effective at removing filter cake from the filter media, resulting in a short cycle of downtime for cleaning the filter media. Therefore, we propose a tubular volume reduction filtration device with fluid disturbance. Summary of the Invention

[0006] The purpose of this invention is to provide a tubular volume reduction filtration device for fluid turbulence, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a tubular reduction filtration device with fluid disturbance, comprising a plurality of tubular filters, wherein the outer wall of each tubular filter is provided with a pulse disturbance mechanism and an ultrasonic mechanism, two adjacent tubular filters are connected in series, the pulse disturbance mechanism comprises a plurality of fluid disturbance components, the fluid disturbance components are fixedly sleeved on the outer wall of the tubular filter, the fluid disturbance components and the ultrasonic mechanism are staggered, the fluid disturbance components are externally connected to a pulse solenoid valve, the pulse solenoid valve is externally connected to a fluid delivery pipe, and the outer wall of the tubular filter is provided with a sewage discharge pipe.

[0008] Furthermore, the fluid disturbance component includes a mounting shell, which is fixedly connected to the outer wall of the tubular filter. The mounting shell is provided with a rotatably connected annular flow guide frame inside. The inner wall of the tubular filter is provided with annular flow guide frames on both sides of the annular flow guide frame. The annular flow guide frame includes two support rings, which are fixedly connected to each other by a number of arc-shaped pieces. The arc-shaped pieces are distributed in a vortex-like annular pattern.

[0009] Furthermore, the fluid disturbance component also includes a support cylinder, a fixing ring is sleeved at the center of the outer wall of the support cylinder, a plurality of first guide blocks are provided on the outer wall of the fixing ring, the outer wall of the first guide blocks is fixedly connected to the inner wall of the support ring, and second guide blocks are provided on both sides of the outer wall of the first guide blocks extending to the side of the fixing ring.

[0010] Furthermore, the first guide block and the second guide block are arranged in a vortex-like ring, the second guide block has a triangular structure, and the end of the second guide block near the support cylinder has a pointed structure.

[0011] Furthermore, the fluid disturbance component also includes an annular spiral guide vane, which is sleeved on the outside of the support cylinder, and the outer wall of the annular spiral guide vane is fixedly connected to the first guide block.

[0012] Furthermore, the annular flow guide includes an annular spiral flow guide plate, which is fixedly connected to the inner wall of the tubular filter. The annular spiral flow guide plate is arranged in parallel with the annular spiral flow guide plate, and a plurality of flow guide holes are opened on the surface of the annular spiral flow guide plate.

[0013] Furthermore, both the annular spiral guide vane and the annular spiral guide vane include two annular spiral strips, with an annular spiral blade between the two annular spiral strips, and the flow-guiding hole is located on the surface of the annular spiral blade; the spiral angles of the annular spiral guide vane and the annular spiral guide vane are opposite, and the spiral angles of the two annular spiral strips are opposite.

[0014] Furthermore, the annular spiral guide vane and the annular spiral guide vane are of equal size, and both the annular spiral guide vane and the annular spiral guide vane are located inside the tubular filter.

[0015] Furthermore, the outer wall of the support ring is provided with an auxiliary ring on the outside of the support cylinder, and the inner wall of the mounting shell is provided with an annular groove that matches the auxiliary ring. The auxiliary ring and the support cylinder are arranged in parallel inside and out, and the auxiliary ring and the support ring are perpendicular to each other.

[0016] Furthermore, the pulse disturbance mechanism includes two fluid disturbance components, one of which is connected to an external air supply device, and the other of which is connected to an external liquid supply device.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention utilizes a series of tubular filters connected in series to reduce the volume of wastewater during filtration. The pulse disturbance mechanism applies pulsed impact agitation to the filter cake inside the tubular filters, effectively loosening and peeling the filter cake from the filter media. The ultrasonic mechanism applies ultrasonic vibration to the filter cake on the outer wall of the tubular filters. The staggered distribution of the fluid disturbance component and ultrasonic mechanism allows for cross-operation of pulsed fluid agitation and ultrasonic treatment of the filter cake at multiple locations on the outer wall of the tubular filters, effectively improving the filter cake peeling effect and ensuring continuous filtration and volume reduction of wastewater by the tubular filters. This design achieves wastewater volume reduction without the use of flocculants, while effectively extending the downtime for cleaning the filter media. The annular flow guide frame diverts fluid from both sides of the annular guide frame. Working in conjunction with the annular flow guide frame, it effectively guides and directs fluid flow, creating multi-angle, multi-directional pulsed fluid disturbance and impact within the tubular filter, thus improving the cleaning and peeling effect on the filter cake. After the fluid enters the mounting housing, it impacts the surface of the arc-shaped plate, which in turn drives the support ring to rotate, causing the annular flow guide frame to rotate as well. The rotating annular flow guide frame, working in conjunction with the annular flow guide frame, further enhances the multi-angle, multi-directional pulsed fluid disturbance and impact within the tubular filter.

[0018] 2. This invention, by setting up annular spiral guide vanes, annular spiral guide vanes, guide holes, annular spiral strips, and annular spiral blades, allows the annular spiral guide vanes to rotate around the outside of the support cylinder along with the annular guide frame. As the fluid passes through the annular spiral guide vanes, it undergoes a rotating spiral guidance process, resulting in multi-angle and multi-directional fluid movement. After passing through the annular spiral guide vanes, the fluid impacts the fixed annular spiral guide vanes, causing the fluid to undergo another annular spiral guidance process. This further effectively increases the multi-angle and multi-directional movement path of the fluid. Simultaneously, after being guided, the fluid flows out through the guide holes, annular spiral guide vanes, and annular spiral guide vanes. The gaps between the plates allow for drainage, effectively ensuring that the fluid impacts the inside of the tubular filter in a multi-angle and multi-directional pulse-like manner. This effectively improves the removal of the filter cake and extends the cycle of downtime for cleaning the filter media. The annular spiral guide vanes and annular spiral guide vanes have opposite spiral angles, resulting in different annular spiral guidance directions for the fluid, effectively increasing the multi-angle and multi-directional movement path of the fluid. The opposite spiral angles of the two annular spiral strips create a double spiral structure, further increasing the multi-angle and multi-directional movement path of the fluid.

[0020] 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. Example 1

[0021] Please see Figures 1-7 This invention provides a technical solution: a tubular reduction filtration device with fluid disturbance, comprising a plurality of tubular filters 1. The outer wall of each tubular filter 1 is provided with a pulse disturbance mechanism 2 and an ultrasonic mechanism 3. Two adjacent tubular filters 1 are connected in series. The pulse disturbance mechanism 2 includes a plurality of fluid disturbance components 4, which are fixedly sleeved on the outer wall of the tubular filters 1. The fluid disturbance components 4 and the ultrasonic mechanism 3 are staggered. Each fluid disturbance component 4 is externally connected to a pulse solenoid valve 5, which is externally connected to a fluid delivery pipe 6. A drain pipe 7 is provided on the outer wall of each tubular filter 1. Each fluid disturbance component 4 includes a mounting shell 401, which is fixedly connected to the outer wall of the tubular filters 1. The mounting shell 401 contains a rotatably connected annular flow guide 402. The inner wall of the tubular filters 1... Annular flow guide frames 403 are respectively provided on both sides of the annular flow guide frame 402. The annular flow guide frame 402 includes two support rings 404, which are fixedly connected by a plurality of arc-shaped pieces 405. The arc-shaped pieces 405 are distributed in annular vortex shape. The fluid disturbance component 4 also includes a support cylinder 406. A fixing ring 407 is sleeved in the center of the outer wall of the support cylinder 406. A plurality of first flow guide blocks 408 are provided on the outer wall of the fixing ring 407. The outer wall of the first flow guide block 408 is fixedly connected to the inner wall of the support ring 404. Second flow guide blocks 409 are provided on both sides of the outer wall of the first flow guide block 408 extending to the side of the fixing ring 407. The pulse disturbance mechanism 2 includes two fluid disturbance components 4. One fluid disturbance component 4 is connected to an external air supply device, and the other fluid disturbance component 4 is connected to an external liquid supply device.

[0022] In one embodiment, the first guide block 408 and the second guide block 409 are arranged in a vortex-like annular pattern. The second guide block 409 has a triangular structure, and one end of the second guide block 409 near the support cylinder 406 has a pointed structure. This ensures that while the fluid impacts the surfaces of the first guide block 408 and the second guide block 409 for flow guidance, the first guide block 408 and the second guide block 409 can push the annular guide frame 402 to rotate, thereby ensuring that the annular spiral guide vane 410 maintains rotation during the fluid impact process.

[0023] In one embodiment, an auxiliary ring 415 is provided on the outer wall of the support ring 404 outside the support cylinder 406, and an annular groove matching the auxiliary ring 415 is provided on the inner wall of the mounting shell 401. The auxiliary ring 415 and the support cylinder 406 are arranged parallel to each other, and the auxiliary ring 415 and the support ring 404 are perpendicular to each other. The rotational cooperation of the auxiliary ring 415 and the annular groove can effectively ensure the stability of the support ring 404 during rotational movement, thereby ensuring the stability of the annular guide frame 402 during rotational movement. At the same time, a sealing structure needs to be arranged between the auxiliary ring 415 and the annular groove, and between the support ring 404 and the inner wall of the mounting shell 401 (an existing mature sealing structure design can be used).

[0024] Working principle of the invention: Refer to the instruction manual appendix Figures 1-7This invention employs a series of tubular filters 1, a pulse disturbance mechanism 2, an ultrasonic mechanism 3, a fluid disturbance component 4, a pulse solenoid valve 5, a fluid delivery pipeline 6, and a sewage discharge pipeline 7. Multiple tubular filters 1 are connected in series to perform volume reduction filtration of wastewater. The pulse disturbance mechanism 2 applies pulse-type impact disturbance to the filter cake inside the tubular filter 1, effectively loosening and peeling the filter cake from the filter medium. The ultrasonic mechanism 3 uses ultrasonic vibration to treat the filter cake on the filter medium on the outer wall of the tubular filter 1, breaking up the hardened filter cake. Simultaneously, the pulse disturbance mechanism 2 pulses the filter cake, discharging the peeled filter cake and filter cake debris from the inside of the filter medium. The fluid disturbance component 4 and the ultrasonic mechanism 3 are staggered, allowing for efficient filtration of the tubular filter. The filter 1's outer wall is subjected to cross-processing of pulsed fluid disturbance and ultrasonic treatment at multiple different locations, which effectively improves the filter cake removal effect and ensures continuous filtration and volume reduction of wastewater. This allows for wastewater volume reduction without the use of flocculants and extends the downtime for cleaning the filter media. The pulse solenoid valve 5 pulses the fluid between the fluid delivery pipe 6 and the fluid disturbance component 4, ensuring the stability of the fluid disturbance impact. The fluid delivery pipe 6 is used to deliver external fluid into the tubular filter 1 through the pulse disturbance mechanism 2, and the drain pipe 7 is used for draining the tubular filter 1. The mounting shell 401 in the fluid disturbance assembly 4 provides installation and rotation space for the annular guide frame 402. The annular guide frame 403 guides the fluid on both sides of the annular guide frame 402. The annular guide frame 403 and the annular guide frame 402 work together to effectively guide and drain the fluid, and can perform multi-angle and multi-directional pulse fluid disturbance and impact on the internal space of the tubular filter 1, which can effectively improve the cleaning and peeling effect of the filter cake. The two support rings 404 in the annular guide frame 402 are closed on the outside of the arc plate 405. After the fluid is sent into the mounting shell 401, the fluid impacts the surface of the arc plate 405. The fluid can push the support rings 404 to rotate through the arc plate 405, so that the annular guide frame 402 rotates. The annular guide frame 402 works with the annular guide frame 403 in a rotating state, which can further improve the multi-angle and multi-directional pulse fluid disturbance and impact on the internal space of the tubular filter 1. The support cylinder 406 supports the fixed ring 407 inside the support ring 404. The fixed ring 407 is fixedly connected to the inner wall of the support ring 404 through the first guide block 408. After the fluid impacts the surface of the arc-shaped plate 405, the fluid enters the space between adjacent first guide blocks 408 through the adjacent gaps of the arc-shaped plate 405. The fluid then exits outward through the gaps between the second guide blocks 409 on both sides of the first guide block 408. The fluid then moves to the outside of the support cylinder 406 and moves from the outside of the support cylinder 406 to the annular guide frame 403. The fluid exits through the gap between the support cylinder 406 and the annular guide frame 403. The support cylinder 406 shields the fluid and guides the direction of fluid movement, preventing the fluid from being directly discharged from the inside of the support ring 404, thus ensuring multi-angle and multi-directional movement of the pulse fluid disturbance impact operation. The pulse disturbance mechanism 2 is designed to include two fluid disturbance components 4. One fluid disturbance component 4 is connected to an external air supply device, and the other fluid disturbance component 4 is connected to an external liquid supply device. Through the above design, the fluid disturbance inside the tubular filter 1 can perform liquid pulse disturbance impact work and airflow pulse disturbance impact work respectively. This can effectively realize multi-media pulse disturbance impact work on the filter cake inside the tubular filter 1, effectively improve the cleaning and peeling effect of the filter cake inside the tubular filter 1, and thus extend the cycle of shutdown cleaning of the filter media. In this invention, the overall structure of the tubular filter 1 (including the tube body, filter medium and its installation and connection design, etc.), the overall structure of the ultrasonic mechanism 3 (ultrasonic transducer, controller, etc.), the series connection method of the tubular filter 1, the design of the pulse solenoid valve 5 and the sewage pipe 7 all adopt existing mature equipment structures. Their transmission principle, sealing structure and control method can all adopt existing mature conventional structural components and conventional control technology. The above contents are common knowledge in the field and are not the object of improvement of this invention. Therefore, they are not explained in detail. Example 2

[0025] Please see Figures 2-4 , Figure 6 and Figures 8-10The present invention provides a technical solution: a tubular flow reduction filtration device with fluid disturbance, wherein the fluid disturbance component 4 further includes an annular spiral guide vane 410, the annular spiral guide vane 410 being sleeved on the outside of the support cylinder 406, and the outer wall of the annular spiral guide vane 410 being fixedly connected to the first guide block 408; the annular flow guide frame 403 includes an annular spiral guide vane 411, the annular spiral guide vane 411 being fixedly connected to the inner wall of the tubular filter 1, the annular spiral guide vane 411 being arranged parallel to the annular spiral guide vane 410, and the surface of the annular spiral guide vane 411 having a plurality of flow holes. 412; The annular spiral guide vane 410 and the annular spiral guide vane 411 each include two annular spiral strips 413, and an annular spiral blade 414 is provided between the two annular spiral strips 413. The guide hole 412 is provided on the surface of the annular spiral blade 414. The spiral angles of the annular spiral guide vane 410 and the annular spiral guide vane 411 are opposite, and the spiral angles of the two annular spiral strips 413 are opposite. The annular spiral guide vane 410 and the annular spiral guide vane 411 are of equal size, and both the annular spiral guide vane 410 and the annular spiral guide vane 411 are located inside the tubular filter 1.

[0026] Working principle of the invention: Refer to the attached diagram in the instruction manual. Figures 2-4 , Figure 6 and Figures 8-10 This invention, by setting an annular spiral guide plate 410, an annular spiral guide plate 411, a guide hole 412, an annular spiral strip 413, and an annular spiral blade 414, allows the annular spiral guide plate 410 to rotate around the support cylinder 406 along with the annular guide frame 402. When the fluid passes through the annular spiral guide plate 410, it undergoes a rotating spiral guide treatment, resulting in multi-angle and multi-directional movement of the fluid. After passing through the annular spiral guide plate 410, the fluid impacts the fixed annular spiral guide plate 411, causing the fluid to undergo annular spiral guide treatment again. This further effectively increases the multi-angle and multi-directional movement path of the fluid. At the same time, after being guided, the fluid is discharged from the guide hole 412 and the gap between the annular spiral guide plate 410 and the annular spiral guide plate 411. This effectively ensures that the fluid performs pulse-type disturbance impact treatment on the inside of the tubular filter 1 from multiple angles and directions, which can effectively improve the peeling effect of the filter cake and extend the cycle of shutdown cleaning of the filter media. In the annular spiral guide vane 410 and the annular spiral guide vane 411, the two annular spiral strips 413 are supported on both sides, and the annular spiral blade 414 is supported between the two annular spiral strips 413. The annular spiral strips 413 and the annular spiral blade 414 perform annular spiral guiding treatment of the fluid, which can effectively ensure multi-angle and multi-directional guiding treatment of the fluid. The annular spiral guide vane 410 and the annular spiral guide vane 411 are designed with opposite spiral angles, so that the annular spiral guide vane 410 and the annular spiral guide vane 411 guide the fluid in different annular spiral directions, which can effectively increase the multi-angle and multi-directional movement path of the fluid; the two annular spiral strips 413 have opposite spiral angles, so that the annular spiral guide vane 410 and the annular spiral guide vane 411 themselves form a double spiral structure, which can further increase the multi-angle and multi-directional movement path of the fluid; The annular spiral guide vane 410 and the annular spiral guide vane 411 are designed to have equal dimensions, ensuring that the inner and outer diameters of the spiral path of the fluid movement through the annular spiral guide vane 410 and the annular spiral guide vane 411 match. This guarantees that the annular spiral guide vane 411 can receive and guide a large amount of fluid rotated and guided by the annular spiral guide vane 410, while also ensuring that the fluid can be discharged from the gap between the annular spiral guide vane 410 and the annular spiral guide vane 411. The annular spiral guide vane 410 and the annular spiral guide vane 411 are both located inside the tubular filter 1, ensuring that the annular spiral guide vane 410 and the annular spiral guide vane 411 can normally drive the fluid to undergo pulse-type disturbance and impact treatment inside the tubular filter 1.

[0027] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
