Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, and in particular to a microfiltration machine. Background Technology

[0002] In aquaculture, microfiltration machines are commonly used to filter water. However, impurities easily adhere to the filter screens, affecting filtration efficiency. Related technologies often use a water pump to create a high-pressure jet of filtered clean water or municipal water to backwash the filter screens. However, this backwashing process turns clean water or municipal water into wastewater, wasting water resources. Furthermore, the long-term operation of the pressurized water pump also wastes electrical energy, and the high-pressure jet method for backwashing the filter screens is ineffective. In addition, because the high-pressure jet directly acts on the filter screens, it can easily damage them, reducing their lifespan.

[0003] Therefore, there is an urgent need for a microfiltration machine to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a microfiltration machine that improves the cleaning effect of the filter screen, saves water resources and water pump power, and ensures the service life of the filter screen.

[0005] To achieve this objective, the present invention adopts the following technical solution: A microfiltration machine, comprising: A rotating drum, the rotating drum including a filter assembly, the filter assembly including a filter frame and a filter screen fixedly connected; A drive device is connected to the drum and configured to drive the drum to rotate about its axis. A sludge collection trough is disposed inside the rotating drum; A vibration device is located outside the drum and above the sludge collection tank, and the vibration device is configured to strike the filter screen frame.

[0006] Alternatively, the sludge collection trough extends along the axial direction of the drum; The vibration device includes a plurality of vibrating elements arranged at intervals along the axial direction of the drum, and the filter screen frame includes a plurality of vibrating impact rings arranged at intervals along the axial direction of the drum. Along the radial direction of the drum, each of the vibrating impact rings is opposite to one of the vibrating elements. Each of the vibrating impact rings includes a plurality of impact protrusions spaced apart along the circumferential direction of the drum, the impact protrusions being located on the outer periphery of the filter frame, and the vibrating element being configured to strike the corresponding impact protrusions.

[0007] As an optional solution, the filter frame further includes: A vibration transmission beam extends along the axial direction of the drum, and the vibration transmission beam is provided between two adjacent vibration impact rings; A vibration buffer beam extends along the circumferential direction of the drum, and the vibration buffer beam is provided between each two adjacent striking protrusions in the vibration striking ring. The cross-sectional moment of the vibration transmission beam is greater than that of the vibration buffer beam.

[0008] As an optional solution, the microfiltration machine further includes a drain pipe and a flushing device, the drain pipe being connected to the sludge collection tank, and the flushing device comprising: A flushing bucket is rotatably connected to the inside of the sludge collection tank via a rotating shaft. The flushing bucket has a water-filling position for receiving water and a pouring position for pouring water into the sludge collection tank. A first limiting member is disposed on the inner wall of the sludge collection tank. The first limiting member can abut against the flushing bucket to position the flushing bucket in the water-filled position. The second limiting member is disposed on the inner wall of the sludge collection tank. The second limiting member can abut against the flushing bucket to position the flushing bucket in the tilting position.

[0009] As an optional solution, when the water level in the flushing bucket does not reach the preset water level, the center of gravity G of the flushing bucket is located below the center O of the rotating shaft, and the center of gravity G of the flushing bucket is located on the side of the center O of the rotating shaft closer to the first limiting member. When the water level in the flushing bucket reaches the preset water level, the center of gravity G of the flushing bucket is located above the center O of the rotating shaft, and the center of gravity G of the flushing bucket is located on the side of the center O of the rotating shaft closer to the second limiting member.

[0010] As an optional solution, the flushing device further includes: The water inlet cup is fixedly installed on the inner wall of the rotating drum. When the rotating drum drives the water inlet cup to rotate from the bottom of the rotating drum to the top of the flushing bucket, the water inlet cup can inject the raw water scooped in the rotating drum into the flushing bucket.

[0011] As an optional solution, the flushing device includes a plurality of water cups, which are arranged at intervals along the circumferential direction of the drum.

[0012] As an optional solution, the drum includes multiple filter components, each of which is arc-shaped, and the multiple filter components are sequentially spliced ​​end to end to form a cylindrical structure.

[0013] As an optional solution, the microfilter also includes a triggering device, which is communicatively connected to the vibration device. The triggering device is used to trigger the vibration device to perform a striking motion. When the splicing position of the filter assembly rotates to the area where the vibration device is striking, the triggering device removes the triggering of the vibration device.

[0014] As an optional solution, the triggering device includes: A trigger body is communicatively connected to the vibration device, and a first contact is provided on the trigger body; A trigger drive, one end of which is rotatably connected to the trigger body, and a second contact is provided on the trigger drive; The other end of the trigger drive is rotatably connected to the roller; Multiple trigger arc-shaped tracks are fixed to the outer periphery of the drum and arranged at intervals along the circumference of the drum. A gap is formed between two adjacent trigger arc-shaped tracks. Along the axial direction of the drum, the gap is directly opposite the splicing position of the filter assembly. When the roller rolls and abuts against the trigger arc-shaped track, the first contact abuts against the second contact. When the roller is located at the gap, the second contact separates from the first contact.

[0015] The beneficial effects of this invention are: The microfiltration machine provided by this invention includes a rotating drum, a driving device, a sludge collection tank, and a vibration device. The rotating drum includes a filter screen assembly, which comprises a filter screen frame and a filter screen fixedly connected together. The driving device is connected to the rotating drum and is configured to drive the rotating drum to rotate around its axis. The sludge collection tank is located inside the rotating drum. The vibration device is located outside the rotating drum and above the sludge collection tank, and is configured to strike the filter screen frame. By incorporating a vibration device that strikes the filter screen frame, the microfiltration machine of this invention uses high-frequency mechanical vibration to detach impurities from the filter screen, causing them to fall into the sludge collection tank below. This ensures effective cleaning of the filter screen and eliminates the need for a high-pressure water jet to rinse it, saving water resources and pump energy. Furthermore, the vibration device acts on the filter screen frame, without direct contact with the filter screen, improving filter screen protection and extending its service life.

[0016] Furthermore, because the drive unit drives the drum to rotate, all positions of the filter assembly in the circumferential direction can rotate to the area where the vibrating device strikes, ensuring the cleaning effect of the vibrating device on all positions of the filter assembly in the circumferential direction.

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0021] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Microfiltration machines in related technologies typically use a water pump to create a high-pressure jet of filtered clean water or municipal water to backwash the filter screen. However, the clean water or municipal water becomes wastewater after backwashing, resulting in water waste. The long-term operation of the booster pump also wastes electrical energy, and the effect of using a high-pressure jet to wash the filter screen is not ideal. Furthermore, because the high-pressure jet acts directly on the filter screen, it can easily damage it, reducing its lifespan.

[0024] To solve the above problems, such as Figures 1-3As shown, this embodiment provides a microfilter, which includes a rotating drum 1, a driving device 2, a sludge collection tank 3, and a vibration device 4. The rotating drum 1 includes a filter assembly 11, which includes a filter frame 111 and a filter 112 fixedly connected. The driving device 2 is connected to the rotating drum 1 and is configured to drive the rotating drum 1 to rotate around the axis of the rotating drum 1. The sludge collection tank 3 is disposed inside the rotating drum 1. The vibration device 4 is located outside the rotating drum 1 and above the sludge collection tank 3. The vibration device 4 is configured to strike the filter frame 111. The microfilter provided in this embodiment uses a vibration device 4 to strike the filter screen frame 111. This high-frequency mechanical vibration causes impurities on the filter screen 112 to detach and fall into the collection tank 3 below, ensuring a clean filter screen 112. This eliminates the need for a high-pressure water jet to rinse the filter screen 112, saving water resources and pump energy. Furthermore, the vibration device 4 acts on the filter screen frame 111 without directly contacting the filter screen 112, improving protection of the filter screen 112 and extending its service life.

[0025] Optionally, in this embodiment, the drive device 2 is a servo motor, which drives the drum 1 to rotate through a transmission device. The transmission device can be a transmission chain, a synchronous belt, or a gear. This embodiment does not limit the specific structure of the transmission device.

[0026] It should be noted that, since the drive device 2 drives the drum 1 to rotate, all positions of the filter assembly 11 in the circumferential direction can rotate to the area where the vibration device 4 strikes, thus ensuring the cleaning effect of the vibration device 4 on all positions of the filter assembly 11 in the circumferential direction.

[0027] In this embodiment, as Figures 1-3 As shown, the microfiltration machine also includes a support device 8, which supports the rotating drum 1, the drive device 2, the sludge collection tank 3, and the vibration device 4. Specifically, the support device 8 includes a support frame 81, a protective cover 82, and a mounting beam 83. The protective cover 82 is mounted on the support frame 81, and the mounting beam 83 is located inside the protective cover 82 and fixedly connected to the support frame 81. The rotating drum 1 is rotatably mounted inside the support frame 81. The drive device 2 and the sludge collection tank 3 are both fixedly mounted on the support frame 81, and the vibration device 4 is mounted on the mounting beam 83. The rotating drum 1, the drive device 2, the sludge collection tank 3, and the vibration device 4 are all located inside the protective cover 82. By providing the protective cover 82, the protection effect for the rotating drum 1, the drive device 2, the sludge collection tank 3, and the vibration device 4 is improved.

[0028] Optionally, in this embodiment, the filter screen 112 is embedded in the filter screen frame 111, and the entire filter screen assembly 11 is manufactured by injection molding, thereby ensuring the connection strength between the filter screen 112 and the filter screen frame 111, and ensuring the structural strength of the entire filter screen assembly 11.

[0029] Optionally, such as Figure 1 As shown, the drum 1 also includes a support frame 12, and a filter screen frame 111 is disposed on the support frame 12. By providing the support frame 12, the structural strength of the entire drum 1 is further improved.

[0030] Optionally, such as Figures 2-4 As shown, the sludge collection tank 3 extends along the axial direction of the drum 1. The vibration device 4 includes multiple vibrating elements 41 spaced apart along the axial direction of the drum 1. The filter screen frame 111 includes multiple vibrating impact rings 1111 spaced apart along the axial direction of the drum 1. In the radial direction of the drum 1, each vibrating impact ring 1111 is opposite to a vibrating element 41. Each vibrating impact ring 1111 includes multiple impact protrusions 11111 spaced apart along the circumferential direction of the drum 1. The impact protrusions 11111 are located on the outer periphery of the filter screen frame 111, and the vibrating element 41 is configured to strike the corresponding impact protrusion 11111. The above arrangement enables the vibration device 4 to strike multiple positions in the axial direction of the filter screen frame 111, thereby ensuring the cleaning effect on each position in the axial direction of the filter screen 112, and also ensuring that the detached debris can reliably fall into the sludge collection tank 3 below. Furthermore, since the striking protrusions 11111 protrude from the outer periphery of the filter screen frame 111, it ensures that the vibrating element 41 can only strike the striking protrusions 11111, thus preventing the vibrating element 41 from accidentally touching the filter screen 112. It should be noted that the mounting beam 83 extends along the axial direction of the drum 1, and multiple vibrating elements 41 are spaced apart on the mounting beam 83. Optionally, the vibrating element 41 is a high-frequency oscillating cylinder. High-frequency oscillating cylinders have the advantage of reliable operation, and can generate high-frequency reciprocating motion of over 2000 rpm, ensuring a cleaning effect on the filter screen 112.

[0031] Optionally, such as Figure 2 and Figure 5As shown, the filter screen frame 111 also includes a vibration transmission beam 1112 and a vibration buffer beam 1113. The vibration transmission beam 1112 extends along the axial direction of the drum 1, and a vibration transmission beam 1112 is provided between each two adjacent vibration impact rings 1111. The vibration buffer beam 1113 extends along the circumferential direction of the drum 1, and a vibration buffer beam 1113 is provided between each two adjacent impact protrusions 11111 in the vibration impact rings 1111. The cross-sectional moment of the vibration transmission beam 1112 is greater than that of the vibration buffer beam 1113. By setting the vibration transmission beam 1112, it is ensured that the vibration transmission beam 1112 transmits mechanical vibration along the axial direction of the drum 1, thereby driving the area of ​​the filter screen frame 111 located in the upper part of the dirt collection tank 3 to vibrate synchronously, ensuring the cleaning effect of each position of the filter screen 112 in the axial direction. Furthermore, by setting the aforementioned vibration buffer beam 1113, the mechanical vibration on the filter screen frame 111 is transmitted less along the circumferential direction of the drum 1, ensuring that the mechanical vibration is concentrated in the area of ​​the filter screen frame 111 located in the upper part of the collection tank 3. This prevents impurities on the filter screen 112 that are not located in the upper part of the collection tank 3 from falling into the raw water in the drum 1, thus ensuring the collection effect of the collection tank 3 on the fallen impurities. It should be noted that the larger the cross-sectional moment, the higher its natural frequency. By making the cross-sectional moment of the vibration transmission beam 1112 greater than that of the vibration buffer beam 1113, the vibration transmission beam 1112 is ensured to have a higher natural frequency, ensuring the vibration transmission effect of the vibration transmission beam 1112. This also ensures that the vibration buffer beam 1113 has a lower natural frequency, ensuring that the vibration buffer beam 1113 transmits less mechanical vibration.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the drum 1 includes multiple filter screen assemblies 11, each of which is arc-shaped. These multiple filter screen assemblies 11 are sequentially spliced ​​end-to-end to form a cylindrical structure. By using multiple filter screen assemblies 11 for splicing and connection, manufacturing costs are reduced, and only damaged filter screen assemblies 11 need to be replaced, thus reducing replacement costs. Optionally, multiple arc-shaped filter screen assemblies 11 are sequentially spliced ​​and connected along the axial direction of the drum 1 to meet the requirements of a large-size drum 1.

[0033] In this embodiment, as Figure 2As shown, the microfiltration machine also includes a triggering device 7, which is communicatively connected to the vibration device 4. The triggering device 7 is used to trigger the vibration device 4 to perform a striking motion. When the splicing position of the filter assembly 11 rotates to the area where the vibration device 4 is striking, the triggering device 7 removes the trigger on the vibration device 4. When the triggering device 7 removes the trigger on the vibration device 4, each vibrating element 41 is in a stopped state, and the piston rod of the vibrating element 41 does not perform high-frequency reciprocating motion, thus avoiding the vibrating element 41 striking the splicing position of the filter assembly 11 and ensuring the reliability of the splicing connection of each filter assembly 11. When the filter assembly 11 rotates to the area where the vibration device 4 is striking, the triggering device 7 triggers the vibration device 4, and each vibrating element 41 is in a powered-on state. The piston rod of the vibrating element 41 performs high-frequency reciprocating motion, ensuring the cleaning effect on the filter 112.

[0034] In this embodiment, as Figure 3 and Figure 6 As shown, the triggering device 7 includes a trigger body 71, a trigger drive 72, a roller 73, and multiple trigger arc-shaped tracks 74. The trigger body 71 is communicatively connected to the vibration device 4 and is mounted on the mounting beam 83. A first contact 711 is provided on the trigger body 71. One end of the trigger drive 72 is rotatably connected to the trigger body 71, and a second contact 721 is provided on the trigger drive 72. The other end of the trigger drive 72 is rotatably connected to the roller 73. Multiple trigger arc-shaped tracks 74 are fixed to the outer periphery of the drum 1 and arranged at intervals along the circumference of the drum 1. A gap 75 is formed between adjacent trigger arc-shaped tracks 74. Along the axial direction of the drum 1, the gap 75 is directly opposite the splicing position of the filter assembly 11. When the roller 73 rolls against the trigger arc-shaped track 74, the roller 73... Under the action of the triggering arc track 74, the triggering drive 72 rotates upward around the rotational connection position between the triggering drive 72 and the triggering body 71, causing the first contact 711 to abut against the second contact 721. At this time, the triggering body 71 triggers the vibration device 4, so that each vibrating element 41 is in the powered-on state. When the triggering arc track 74 rotates with the drum 1 and the roller 73 is at the gap 75, since the triggering arc track 74 no longer provides support for the roller 73, the triggering drive 72 rotates downward around the rotational connection position between the triggering drive 72 and the triggering body 71 under its own gravity, causing the second contact 721 to separate from the first contact 711. At this time, the triggering body 71 removes the triggering of the vibration device 4, and each vibrating element 41 is in the stopped state. The above-mentioned triggering device 7 has a simple structural design and reliable operation. It should be noted that the specific mechanism and working principle of the triggering body 71 triggering the vibration device 4 are existing technologies and will not be described in detail here.

[0035] In this embodiment, as Figure 3 and Figure 4 As shown, the microfiltration unit also includes a drain pipe 5 and a flushing device 6. The drain pipe 5 is connected to the sludge collection tank 3. The flushing device 6 includes a flushing bucket 61, a first limiting member 63, and a second limiting member 64. The flushing bucket 61 is rotatably connected to the inside of the sludge collection tank 3 via a rotating shaft 62. The flushing bucket 61 has a water-filling position relative to the sludge collection tank 3 and a pouring position for filling the sludge collection tank 3. The first limiting member 63 and the second limiting member 64 are both disposed on the inner wall of the sludge collection tank 3. The first limiting member 63 can abut against the flushing bucket 61 to position the flushing bucket 61 in the water-filling position, and the second limiting member 64 can abut against the flushing bucket 61 to position the flushing bucket 61 in the pouring position. The above configuration allows the flushing bucket 61 to periodically flush water into the sludge collection tank 3, and the wastewater after flushing the sludge collection tank 3 can be discharged through the drain pipe 5, achieving periodic cleaning of the sludge collection tank 3. Because the flushing bucket 61 regularly cleans the sludge collection tank 3, water resources are saved, and the high concentration of impurities in the generated wastewater reduces the amount of wastewater to be treated. In addition, by setting the first limiting member 63 and the second limiting member 64, the stability and reliability of the flushing bucket 61 in the water-filling position and the pouring position are ensured.

[0036] Optionally, in this embodiment, the first limiting member 63 is in the form of a limiting plate. The first limiting member 63 is L-shaped, with one sidewall fixed to the inner wall of the sludge collection tank 3, and the other sidewall used to abut against the flushing bucket 61. Optionally, in this embodiment, the second limiting member 64 is in the form of a limiting post.

[0037] Optionally, in this embodiment, as Figure 4 and Figure 7 As shown, along the axial direction of the drum 1, the flushing bucket 61 is located at one end of the sludge collection tank 3, and the drain pipe 5 is connected to the other end of the sludge collection tank 3, ensuring the cleaning effect of the water poured from the flushing bucket 61 on all parts of the sludge collection tank 3. Optionally, the bottom wall of the sludge collection tank 3 slopes downward from one end of the flushing bucket 61 to the end connected to the drain pipe 5, and the drain pipe 5 is connected to the lowest point of the bottom wall of the flushing bucket 61, thereby ensuring the effective discharge of sewage from the sludge collection tank 3 by the drain pipe 5.

[0038] In this embodiment, as Figure 8 and Figure 9As shown, when the water level in the flushing bucket 61 has not reached the preset water level, the center of gravity G of the flushing bucket 61 is located below the center O of the rotating shaft 62, and the center of gravity G of the flushing bucket 61 is located on the side of the center O of the rotating shaft 62 closer to the first limiting member 63, thereby ensuring that the flushing bucket 61 and the first limiting member 63 are in a stable contact state, ensuring that the flushing bucket 61 is positioned in the water-filling position for receiving water; when the water level in the flushing bucket 61 reaches the preset water level, the center of gravity G of the flushing bucket 61 is located above .... When the center of gravity G moves to the side of the pivot 62 closest to the second limiting member 64, the flushing bucket 61 rotates around the center O of the pivot 62 towards the side of the second limiting member 64 until it comes into contact with the second limiting member 64. This positions the flushing bucket 61 in a pouring position to fill the sludge collection tank 3, ensuring that the flushing bucket 61 pours the water into the sludge collection tank 3. After the water in the flushing bucket 61 has been emptied, the offset distance between the weight of the flushing bucket 61 and the center of gravity G generates a reset torque, causing the empty flushing bucket 61 to return to the water-filling position. This configuration allows for automatic switching of the flushing bucket 61's position simply by designing its shape, eliminating the need for a drive device to switch its position. This results in a simple structure, reliable operation, and low cost. In this embodiment, the preset water level refers to the flushing bucket 61 being at its full capacity.

[0039] In this embodiment, as Figure 3 As shown, the flushing device 6 also includes a water inlet cup 65, which is fixedly mounted on the inner wall of the rotating drum 1. When the rotating drum 1 drives the water inlet cup 65 to rotate from the bottom of the drum 1 to the top of the flushing bucket 61, the water inlet cup 65 can inject the raw water scooped from the rotating drum 1 into the flushing bucket 61. By injecting the raw water in the rotating drum 1 into the flushing bucket 61 to flush the sludge collection tank 3, there is no need to use filtered water or municipal water, thus saving clean water resources. In addition, by rotating the drum 1 to drive the water inlet cup 65 to rotate, the water inlet cup 65 can scoop water from the rotating drum 1 and inject it into the flushing bucket 61, making the structure simple and the design ingenious.

[0040] Optionally, such as Figure 3 As shown, the flushing device 6 includes multiple water cups 65, which are arranged at intervals along the circumferential direction of the rotating drum 1. By setting multiple water cups 65, the water injection speed into the flushing tank 61 is effectively increased. The specific number of water cups 65 can be adjusted according to the capacity of the flushing tank 61 and the frequency of flushing by the flushing tank 61.
