Description

Technical Field

[0001] This utility model relates to the field of liquid filtration technology, specifically a continuous production filtration device. Background Technology

[0002] In industrial production and people's livelihood sectors, liquid filtration is an indispensable key link to ensure product quality, production safety and environmental compliance. As the industry continues to increase its requirements for filtration efficiency, accuracy and continuity, traditional liquid filtration devices have gradually exposed many technical shortcomings and are unable to meet the needs of modern production.

[0003] Liquid filtration devices are mostly single-chamber structures, meaning they process liquids using only one set of filter components. When the filter components become saturated due to impurities, the entire filtration process must be paused, disassembled, cleaned, and the filter screen replaced before restarting. This makes continuous filtration impossible. Furthermore, the filter screens are mostly flat or cylindrical and are fixed structures, lacking a design to guide the orderly flow of liquids. This affects the efficiency of the device's liquid filtration and fails to meet the modern industrial demand for "continuous, efficient, and high-precision" filtration. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a continuous production filtration device that solves the problems described in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous production filtration device, comprising a filter box, and further comprising: a partition plate disposed within the inner cavity of the filter box, dividing the interior of the filter box into left and right chambers; a switching component disposed above the partition plate within the filter box, which rapidly switches the liquid to be filtered between the left and right chambers of the filter box for filtration, thereby achieving uninterrupted continuous filtration; and a filter assembly disposed on the left and right sides inside the filter box, with a fan wheel disposed above the filter assembly. After the liquid enters the filter box and passes through the switching component, its flow direction changes, impacting the fan wheel. During the rotation of the fan wheel, the filter assembly rotates within the filter box, enabling centrifugal filtration of impurities within the liquid.

[0006] Furthermore, the bottom of the wind turbine is provided with an installation groove, and a filter assembly is installed inside the installation groove through a threaded structure.

[0007] Furthermore, the filter assembly includes a support rod, a filter screen, an impurity concentration sensor, and a base. The filter screen is installed on the outer side of the support rod, and the mesh size on the surface of the filter screen decreases from top to bottom. An impurity concentration sensor is embedded in the lower surface of the support rod, and a base is rotatably installed on the bottom of the support rod.

[0008] Furthermore, the filter screen has an "S" shaped cross-section, and the base is fixedly connected to the inner wall of the filter box by a threaded structure.

[0009] Furthermore, the top of the filter box is provided with a liquid inlet, and the bottom left and right sides of the filter box are provided with discharge outlets through a threaded structure.

[0010] Furthermore, the switching assembly includes a guide plate, a motor, and rotating blocks. The guide plate is rotatably installed in the inner cavity of the filter box, and the rotating shaft of the guide plate passes through the outside of the filter box and is fixedly connected to the output end of the motor. Rotating blocks are installed on both sides of the guide plate.

[0011] Furthermore, a limiting groove is formed on the inner wall of the filter box, and a rotating block is installed inside the limiting groove.

[0012] Furthermore, the cross-section of the limiting groove has a semi-circular arc structure.

[0013] This utility model has the following beneficial effects: 1. This continuous production filtration device, by setting filtration components on the left and right sides inside the filtration box, and adopting a graded design with the mesh size decreasing from top to bottom, further traps smaller fine impurities, achieving a graded filtration effect of "coarse filtration first, then fine filtration". This not only improves filtration accuracy but also prevents small meshes from being blocked by large impurities too early, extending the service life of the filter screen. Furthermore, the "S"-shaped cross-section of the filter screen increases the contact area between the filter screen and the liquid, while guiding the liquid to form a spiral flow on the filter screen surface, extending the filtration path. When the filtration components rotate, the centrifugal force generated by the liquid driving the impeller to rotate the filtration components causes impurities in the liquid to be thrown outward, accelerating the movement of impurities towards the filter screen surface and being trapped. At the same time, it pushes the filtered clear liquid to flow inward towards the filter screen. Compared with traditional gravity filtration, centrifugal force significantly improves the filtration speed and impurity trapping efficiency.

[0014] 2. This continuous production filtration device has a switching component installed above the internal partition plate of the filter box. An impurity concentration sensor detects the impurities in the liquid at the bottom of the filter box. When the impurity concentration sensor detects that the impurities in the liquid at the bottom of the filter screen reach a preset value, the sensor transmits an "filter screen saturation" electrical signal to the device's control system. The motor receives the signal and drives the guide plate to rotate to the other side. At this time, the rotating block slides synchronously along the limiting groove, and the guide plate switches the liquid flow to the right chamber. The liquid is then filtered by the filter component inside the right chamber. Through the alternating mode of "one chamber for filtration, one chamber for maintenance", the liquid is continuously processed without interruption, thereby improving the working efficiency of the device in liquid filtration.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] The following is based on Figures 1-8 This invention describes a continuous production filtration device provided in an embodiment of the present invention.

[0020] Please see Figures 1-8This utility model provides a technical solution: a continuous production filtration device, including a filter box 1, and further including: a partition plate 2, which is disposed in the inner cavity of the filter box 1, dividing the interior of the filter box 1 into left and right chambers; a switching component 3, which is disposed above the partition plate 2 inside the filter box 1, and the liquid to be filtered is quickly switched to the left and right chambers of the filter box 1 for filtration, so as to realize uninterrupted continuous filtration; and a filter assembly 5, which is disposed on the left and right sides inside the filter box 1, and a fan wheel 4 is disposed above the filter assembly 5. After the liquid enters the interior of the filter box 1 and changes its flow direction after passing through the interior of the switching component 3, it impacts the fan wheel 4. During the rotation of the fan wheel 4, the filter assembly 5 is driven to rotate inside the filter box 1, which can perform centrifugal filtration of impurities inside the liquid.

[0021] The bottom of the impeller 4 has an installation groove 401. The filter assembly 5 is installed inside the installation groove 401 by a threaded structure. The filter assembly 5 includes a support rod 501, a filter screen 502, an impurity concentration sensor 503, and a base 504. The filter screen 502 is installed on the outside of the support rod 501. The mesh size on the surface of the filter screen 502 decreases from top to bottom. The impurity concentration sensor 503 is embedded in the lower surface of the support rod 501. The base 504 is rotatably installed at the bottom of the support rod 501. The cross-section of the filter screen 502 is "S" shaped. The base 504 is fixedly connected to the inner wall of the filter box 1 by a threaded structure. The top of the filter box 1 has a liquid inlet 101. The bottom left and right sides of the filter box 1 have discharge ports 6 installed by a threaded structure. For details, please refer to [link / reference]. Figures 1 to 8As shown, when the liquid to be filtered enters the filter box 1 through the inlet 101 for filtration, the liquid flows in and is guided into the left cavity inside the filter box 1 by the guide plate 301. At this time, the kinetic energy carried by the liquid will directly act on the impeller 4 above the left cavity. Since the blades of the impeller 4 are designed with an inclination, when the liquid impacts the blades of the impeller 4, it will generate a thrust along the inclination direction of the blades, causing the impeller 4 to rotate at high speed around its central axis. When the impeller 4 rotates, it drives the filter assembly 5 to rotate synchronously. Since the base 504 of the filter assembly 5 has an external thread on the outside, it is completely matched with the internal thread structure at the bottom of the left cavity of the filter box 1. It is fixed to the filter by tightening the thread. The inner wall of chamber 1 keeps the base 504 stationary. Because the mesh of filter screen 502 adopts a graded design with decreasing sizes from top to bottom, when liquid enters the chamber, it first contacts the larger mesh area at the top of filter screen 502, trapping larger impurities. As the liquid flows downwards under centrifugal force, it enters the smaller mesh area, further trapping smaller, finer impurities. This achieves a graded filtration effect of "coarse filtration followed by fine filtration," improving filtration accuracy and preventing the small mesh from being clogged prematurely by large impurities, thus extending the service life of filter screen 502. The support rod 501 serves as the core support structure, with the filter screen 502 wrapped around its outer side. The cross-section is S-shaped, which increases the contact area between the filter screen 502 and the liquid. It also guides the liquid to form a spiral flow on the surface of the filter screen 502, extending the filtration path. The base 504 is fixed to the inner wall of the filter box 1 via a threaded structure, ensuring that the base 504 remains stationary when the filter assembly 5 rotates. Only the support rod 501 and the filter screen 502 rotate with the impeller 4. The centrifugal force generated by the liquid-driven impeller 4 rotating the filter assembly 5 causes impurities in the liquid to be thrown outwards, accelerating their movement towards the surface of the filter screen 502 and their interception. Simultaneously, it pushes the filtered clear liquid towards the inside of the filter screen 502. Compared to traditional gravity filtration… Centrifugal force significantly improves filtration speed and impurity retention efficiency. After filtration, the impurity concentration sensor 503 detects the impurities in the liquid at the bottom of the filter box 1. When the impurity concentration sensor 503 detects that the impurities in the liquid at the bottom of the filter screen 502 have reached a preset value, the electrical signal detected by the impurity concentration sensor 503 is transmitted to the control system of the device. After receiving the signal, the control system immediately triggers the subsequent chamber switching component 3 to ensure that the filtration work is not interrupted. When the device switches to the right chamber filtration, the personnel rotate the discharge port 6 to separate the bottom of the pre-filter box 1, so that the filter component 5 can be taken out from the inside of the filter box 1 for cleaning.

[0022] The switching assembly 3 includes a guide plate 301, a motor 302, and a rotating block 303. The guide plate 301 is rotatably installed in the inner cavity of the filter box 1. The rotating shaft of the guide plate 301 passes through the outside of the filter box 1 and is fixedly connected to the output end of the motor 302. The rotating blocks 303 are installed on both sides of the guide plate 301. A limiting groove 7 is opened on the inner wall of the filter box 1, and the rotating blocks 303 are installed inside the limiting groove 7. For details, please refer to [link / reference]. Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, when liquid enters the filter box 1 through the inlet 101 for filtration, the liquid flows into the left chamber of the filter box 1 through the guide plate 301. When the left chamber filter assembly 5 reaches the preset filtration time or the amount of impurities accumulated, the motor 302 receives the signal and drives the guide plate 301 to rotate to the other side. At this time, the rotating block 303 slides synchronously along the limiting groove 7, and the guide plate 301 switches the liquid flow to the right chamber, so that the left chamber enters the stage of pausing filtration, cleaning or replacing components, while the right chamber continues to perform filtration. Conversely, when the right chamber needs maintenance, the guide plate 301 switches again, and the liquid flows back into the left chamber. Through the alternating mode of "one chamber for filtration and one chamber for maintenance", the liquid is continuously processed without interruption. The rotating blocks 303 on both sides of the guide plate 301 are embedded in the limiting groove 7 on the inner wall of the filter box 1. The limiting groove 7 provides a stable sliding trajectory for the rotating blocks 303, ensuring that the guide plate 301 always stays in the preset plane when rotating, avoiding deviation that could lead to liquid leakage or flow failure.

[0023] In use, after the liquid to be filtered enters through the inlet 101 at the top of the filter box 1, it first contacts the guide plate 301 above the partition plate 2 and is guided into the left chamber, impacting the impeller 4 above the chamber. The blades of the impeller 4 are designed with an inclination and rotate at high speed under the kinetic energy of the liquid. Its bottom drives the filter assembly 5 to rotate synchronously through the threaded mounting groove 401. The base 504 of the filter assembly 5 is threadedly fixed to the inner wall of the filter box 1. Only the support rod 501 and the filter screen 502 rotate with the impeller 4. The filter screen 502 has an "S" shaped cross-section with larger mesh openings at the top and smaller openings at the bottom. The liquid first passes through the larger mesh openings at the top to trap large impurities, and then flows with centrifugal force. Fine impurities are trapped in the small mesh at the bottom, while centrifugal force accelerates the adhesion of impurities to the filter screen 502, improving filtration efficiency. The impurity concentration sensor 503 on the support rod 501 monitors the liquid impurities at the bottom of the filter screen 502 in real time. When the impurities reach the preset value, the sensor sends a signal to the control system, which then drives the motor 302 to rotate the guide plate 301 to switch, guiding the liquid into the right chamber for continued filtration, while pausing in the left chamber to remove the filter component 5 for cleaning and maintenance. Conversely, when the right chamber is saturated, the same switching occurs. Through the alternating mode of "one chamber for filtration, one chamber for maintenance", uninterrupted liquid processing is achieved.
