Description

Technical Field

[0001] This utility model relates to a water filtration device, and more particularly to a filtration apparatus. Background Technology

[0002] With the rapid development of industrial automation technology, environmental impact issues are becoming increasingly prominent. Cleaning operations in manufacturing require the use of large quantities of solvents and detergents. Directly discharging wastewater would place a significant burden on the environment. Therefore, it is necessary to treat the wastewater with chemical reagents before discharge. However, in pursuit of efficient wastewater discharge, current methods often discharge wastewater before it has fully reacted, making it difficult to effectively improve wastewater treatment. Therefore, there is an urgent need for equipment that can better improve wastewater treatment efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a filtration device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A filtration device includes: a stirring tank with a stirring mechanism inside; a filter tank with a mixing chamber inside, a feed pipe connecting the mixing chamber and the stirring tank, a drain pipe with a control valve on the bottom side of the mixing chamber, and a water outlet pipe on one side of the bottom of the filter tank; a dispersing mechanism located on the top side of the filter tank, the dispersing mechanism having a dispersing rod that can extend into the mixing chamber; and a filter plate located inside the filter tank, below the feed pipe.

[0006] This technical solution has at least the following beneficial effects: Wastewater to be discharged is first fed into a mixing tank, where a stirring mechanism ensures uniform dispersion of particulate matter. Then, it is fed into a mixing tank through a feed pipe. Chemical reagents can be added to the mixing tank to dilute and mix the wastewater. A dispersing rod extending into the mixing tank further promotes the dispersion and mixing of the wastewater and chemical reagents, ensuring sufficient contact and a more uniform reaction, thus shortening the reaction time. The control valve is then opened, and the reacted wastewater is discharged downwards through a drain pipe onto a filter plate. The filter plate filters out large particles such as flocculent material, resulting in treated and filtered water, which is then discharged through an outlet pipe. By stirring the wastewater before treatment and dispersing it during the reaction, sufficient contact between particulate matter and chemical reagents is promoted, thereby shortening the chemical reaction time. The filtered wastewater is then discharged, effectively improving the quality and efficiency of wastewater treatment.

[0007] As a further improvement to the above technical solution, the dispersing mechanism includes a translational drive and a rotary drive. A clearance groove is provided on the top side of the filter box. The translational drive is connected to the top side of the filter box and has a translational end that can reciprocate horizontally. The translational end extends into the filter box from the clearance groove. The rotary drive is located at the translational end and is driven by the dispersing rod. When chemical reagents are added to the mixing tank, the dispersing rod can reciprocate horizontally, stirring and dispersing the wastewater and chemical reagents in the mixing tank. Specifically, the translational drive, which drives the dispersing rod to reciprocate horizontally, is installed on the top side of the filter box, reducing the space occupied inside the filter box. The rotary drive is installed on the translational end of the translational drive, providing rotational driving force to the dispersing rod, allowing the dispersing rod to move back and forth and rotate within the mixing tank, promoting the reaction between the chemical reagents and particulate matter in the wastewater and shortening the time required for chemical treatment.

[0008] As a further improvement to the above technical solution, a lifting drive is connected between the translation end and the rotary drive, and the lifting drive can drive the rotary drive to move up and down. Because a lifting drive is provided between the translation end and the rotary drive, during operation, the lifting drive provides a driving force to the dispersing rod in the up-down direction, causing the dispersing rod to move in the up-down direction, allowing it to reach a designated position to disperse and mix the wastewater and chemical reagents in the mixing tank. Alternatively, the dispersing rod can move up and down during rotation to further promote the dispersion and mixing of wastewater and chemical reagents in the mixing tank, thereby effectively improving the working effect of the dispersing rod.

[0009] As a further improvement to the above technical solution, a fixing plate is connected inside the filter box. The fixing plate has clearance holes for the sewage pipe to pass through. A first vibration motor is connected to the top side of the fixing plate, and the mixing box is connected to the vibration end of the first vibration motor. During operation, the first vibration motor causes the mixing box to vibrate, thereby achieving multiple mixing of sewage and chemical reagents. This process significantly improves mixing efficiency, ensures sufficient reaction between the chemical reagents and sewage, and helps to further shorten the chemical reaction time and improve sewage treatment and discharge efficiency.

[0010] As a further improvement to the above technical solution, a second vibration motor is connected to the inner side of the filter box, and one side of the filter plate is connected to the vibration end of the second vibration motor. When sewage is discharged from the drain pipe to the filter plate, the second vibration motor operates, driving the filter plate to vibrate. The vibration of the filter plate helps to break the filter cake layer, which helps to prevent the filter medium from clogging and allows for better separation of solid particles and liquid, thereby maintaining or increasing the filtration speed. Furthermore, the vibration of the filter plate makes the thickness of the filter cake layer more uniform, reducing filtration resistance and reducing the use of chemical filter aids to a certain extent, thus reducing energy consumption. In addition, vibration can reduce the clogging of gaps during the filtration process, making filtration more uniform and improving the filtration effect.

[0011] As a further improvement to the above technical solution, a slider is connected to the side of the filter plate away from the second vibration motor, and a groove is provided in the filter box opposite the slider, with the slider engaging within the groove. The connection between the slider and the groove on one side of the filter plate serves to limit the connection of the filter plate. During operation, the second vibration motor drives the filter plate to vibrate on one side, while the other side of the filter plate moves up and down within the filter box, thereby improving the stability of the filter plate during operation and preventing structural damage.

[0012] As a further improvement to the above technical solution, multiple filter plates are arranged at intervals along the vertical direction. Wastewater discharged from the drain pipe passes through multiple filter plates in sequence, and the wastewater is filtered and purified multiple times by the multiple filter plates, which can further improve the cleanliness of the discharged water and promote recycling.

[0013] As a further improvement to the above technical solution, a water guide plate is provided on the inner bottom side of the filter box, and the water guide plate extends downward at an inclination close to the outlet pipe. When the filtered water is discharged to the bottom of the filter box, it can be guided along the inclination of the water guide plate to flow to the outlet pipe, thereby improving the discharge efficiency of the filtered water and reducing the accumulation of water at the bottom of the filter box.

[0014] As a further improvement to the above technical solution, the stirring mechanism includes a drive motor connected to the outside of the stirring tank and a stirring paddle connected to the inside of the stirring tank. One end of the stirring paddle extends out of the stirring tank and is driven by the drive motor. When wastewater is input into the stirring tank, the drive motor drives the stirring paddle to rotate, thereby stirring the wastewater inside the tank, breaking up the agglomeration of particles in the wastewater, promoting full contact and reaction between particles and chemical reagents in the wastewater, and keeping the wastewater in a flowing state to reduce the deposition of particles in the wastewater.

[0015] As a further improvement to the above technical solution, a door is provided on one side of the filter box. When maintenance is required inside the filter box, such as replacing the filter plate, the door can be opened to expose the internal space of the filter box, improving the convenience of use and maintenance.

[0025] Reference Figure 1 and Figure 2 A filtration device includes a mixing tank 100, a filter tank 200, a dispersing mechanism, and a filter plate 410. The mixing tank 100 houses the mixing mechanism. The filter tank 200 houses a mixing chamber 210, which is connected to the mixing tank 100 by a feed pipe. A drain pipe 211 is located on the bottom side of the mixing chamber 210, and a control valve is installed on the drain pipe 211. The control valve, such as a solenoid valve, controls the opening and closing of the drain pipe 211. A water outlet pipe 220 is located on one side of the bottom of the filter tank 200. The dispersing mechanism is located on the top side of the filter tank 200 and has a dispersing rod that can extend into the mixing chamber 210. The filter plate 410 is located inside the filter tank 200, below the feed pipe.

[0026] As described above, the wastewater to be discharged is first fed into the mixing tank 100, where the mixing mechanism stirs the wastewater to ensure uniform dispersion of particulate matter. Then, it is fed into the mixing tank 210 through the feed pipe. Chemical reagents can be added to the mixing tank 210 to dilute and mix the wastewater. The dispersing rod extending into the mixing tank 210 further promotes the dispersion and mixing of the wastewater and chemical reagents, ensuring sufficient contact and a more uniform reaction, thus shortening the reaction time. Then, the control valve is opened, and the reacted wastewater is discharged downwards through the drain pipe 211 onto the filter plate 410. The filter plate 410 filters out large particles such as flocculent material after the reaction, resulting in treated and filtered water, which is then discharged from the outlet pipe 220. By stirring the wastewater before treatment and dispersing it during the reaction, sufficient contact between particulate matter and chemical reagents is promoted, thereby shortening the chemical reaction time. The filtered water is then discharged, effectively improving the quality and efficiency of wastewater treatment.

[0027] The dispersion mechanism is mainly used to stir and disperse chemical reagents and sewage in the mixing tank 210. In this embodiment, the dispersion rod can also move back and forth in the mixing tank 210 to promote the mixing of chemical reagents and sewage. Specifically, the dispersion mechanism includes a translation drive 310 and a rotation drive 320. The top side of the filter tank 200 is provided with a clearance groove 230. The translation drive 310 is connected to the top side of the filter tank 200. The translation drive 310 has a translation end that can reciprocate in the horizontal direction. The translation end extends into the filter tank 200 from the clearance groove 230. The rotation drive 320 is disposed at the translation end and is driven and connected to the dispersion rod. When chemical reagents are added to the mixing tank 210, the dispersing rod can reciprocate horizontally, stirring and dispersing the wastewater and chemical reagents within the mixing tank 210. Specifically, the translational drive 310, which drives the dispersing rod to reciprocate horizontally, is installed on the top side of the filter tank 200, reducing the space occupied inside the filter tank 200. The rotary drive 320 is installed on the translational end of the translational drive 310, providing rotational driving force to the dispersing rod, thereby allowing the dispersing rod to move back and forth and rotate within the mixing tank 210, promoting the reaction between the chemical reagents and particulate matter in the wastewater, and shortening the time required for chemical treatment.

[0028] In practical applications, the translation drive component 310 can take various structural forms, such as an electric lead screw, a pneumatic cylinder, or a hydraulic cylinder. Specifically, when the translation drive component 310 is an electric lead screw, two connecting seats are horizontally spaced on the top side of the filter box 200. A screw is rotatably connected between the two connecting seats, and the screw is driven by a motor. A sliding seat is threadedly connected to the outer side of the screw, and the sliding seat is slidably connected to the clearance groove 230. At this time, the sliding seat is the translation end. When the motor drives the screw to rotate, it can drive the sliding seat to move back and forth in the clearance groove 230, which can drive the rotary drive component 320 and the dispersing rod to move back and forth in the filter box 200. The rotary drive component 320 is used to provide rotational driving force for the dispersing rod. For example, the rotary drive component 320 can be a motor.

[0029] Furthermore, a lifting drive is connected between the translation end and the rotary drive 320. The lifting drive can drive the rotary drive 320 to move up and down. In practical applications, the lifting drive can have various structural forms; for example, an electric telescopic rod can be used. Because a lifting drive is provided between the translation end and the rotary drive 320, during operation, the lifting drive provides a driving force to the dispersing rod in the up-down direction, allowing the dispersing rod to reach a designated position to disperse and mix the wastewater and chemical reagents in the mixing tank 210. Alternatively, the dispersing rod can move up and down during rotation to further promote the dispersion and mixing of wastewater and chemical reagents in the mixing tank 210, thereby effectively improving the working effect of the dispersing rod.

[0030] In the above embodiment, the mixing box 210 can be directly fixed inside the filter box 200. However, to further improve the mixing efficiency within the filter box 200, in this embodiment, a fixing plate 240 is connected inside the filter box 200. The fixing plate 240 has clearance holes for the sewage pipe 211 to pass through. A first vibration motor 250 is connected to the top side of the fixing plate 240, and the mixing box 210 is connected to the vibration end of the first vibration motor 250. During operation, the first vibration motor 250 causes the mixing box 210 to vibrate, thereby achieving multiple mixing of sewage and chemical reagents. This process significantly improves mixing efficiency, ensures sufficient reaction between the chemical reagents and sewage, and helps to further shorten the chemical reaction time and improve sewage treatment and discharge efficiency.

[0031] To facilitate the assembly and disassembly of the mixing box 210 and the first vibration motor 250, a support plate can be connected to the vibration end of the first vibration motor 250, and the mixing box 210 can be fixed to the support plate. When it is necessary to clean the mixing box 210, the mixing box 210 can be directly removed from the support plate.

[0032] To further improve the filtration efficiency of the filter plate 410 for wastewater, in this embodiment, a second vibration motor 420 is connected to the inner side of the filter box 200, and one side of the filter plate 410 is connected to the vibration end of the second vibration motor 420. When wastewater is discharged from the drain pipe 211 into the filter plate 410, the second vibration motor 420 operates, driving the filter plate 410 to vibrate. The vibration of the filter plate 410 helps to break the filter cake layer, which is beneficial to prevent the filter medium from clogging and can better separate solid particles from liquid, thereby maintaining or increasing the filtration speed. Furthermore, the vibration of the filter plate 410 can make the thickness of the filter cake layer more uniform, reduce filtration resistance, and reduce the use of chemical filter aids to a certain extent, thereby reducing energy consumption. In addition, vibration can reduce the clogging of gaps during the filtration process, making the filtration more uniform and improving the filtration effect.

[0033] The filter plate 410 can be relatively fixed within the filter box 200 solely by its connection to the second vibration motor 420. However, this results in poor structural stability after prolonged use. Therefore, to further improve the structural stability of the filter plate 410, in this embodiment, a slider is connected to the side of the filter plate 410 away from the second vibration motor 420. A groove is provided in the filter box 200 opposite the slider, and the slider is fitted into the groove. The connection between the slider and the groove on one side of the filter plate 410 serves to limit the connection of the filter plate 410. During operation, the second vibration motor 420 drives the filter plate 410 to vibrate on one side, while the other side of the filter plate 410 moves up and down within the filter box 200, thereby improving the stability of the filter plate 410 during operation and preventing structural damage.

[0034] Furthermore, multiple filter plates 410 are spaced apart along the vertical direction. Wastewater discharged from the drain pipe 211 passes sequentially through these multiple filter plates 410, undergoing multiple filtrations and purifications. This further improves the cleanliness of the discharged water and promotes recycling. When multiple filter plates 410 are present, an equal number of second vibration motors 420 are installed inside the filter box 200 to drive the multiple filter plates 410 to vibrate. Slider blocks are connected to the side of each filter plate 410 away from the second vibration motors 420, and these sliders are slidably connected to the same groove.

[0035] To improve the efficiency of wastewater discharge, in this embodiment, a water guide plate 260 is provided on the inner bottom side of the filter box 200. The water guide plate 260 extends downward at an incline near the outlet pipe 220. When the filtered water is discharged to the bottom of the filter box 200, it can be guided by the incline of the water guide plate 260 to flow into the outlet pipe 220, thereby improving the discharge efficiency of the filtered water and reducing the accumulation of water at the bottom of the filter box 200.

[0036] The stirring mechanism is mainly used to agitate the sewage in the mixing tank 100. Specifically, for example... Figure 3As shown, the stirring mechanism includes a drive motor 110 connected to the outside of the stirring tank 100 and a stirring paddle 120 connected inside the stirring tank 100. One end of the stirring paddle 120 extends out of the stirring tank 100 and is drivenly connected to the drive motor 110. The stirring paddle 120 includes a rod extending axially along the stirring tank 100, and multiple stirring rods are evenly arranged on the outside of the rod, thereby stirring and mixing the sewage in the stirring tank 100. When sewage is input into the stirring tank 100, the drive motor 110 drives the stirring paddle 120 to rotate, using the stirring paddle 120 to stir the sewage in the stirring tank 100, breaking the agglomeration of particles in the sewage, promoting full contact and reaction between particles in the sewage and chemical reagents, and keeping the sewage in a flowing state, reducing the deposition of particles in the sewage.

[0037] In some embodiments, a door 270 is provided on one side of the filter box 200, and the door 270 can be fixed to the outside of the filter box 200 by means of hinges. When maintenance is required inside the filter box 200, such as when the filter plate 410 needs to be replaced, the door 270 can be opened to expose the internal space of the filter box 200, improving the convenience of use and maintenance. In addition, a handle can be installed on the outside of the door 270 to facilitate opening the door 270.

[0038] In some embodiments, a control panel may be installed on the filter box 200 below the door 270. The control panel has a display screen, which allows for convenient control of the entire filtration device's operating status. The mixing tank 100 and the filter box 200 can be placed and fixed on the same platform, facilitating easy relocation of the entire unit. Anti-slip sleeves are fixedly installed on the bottom side of the platform to enhance its stability and reduce positional shifts during operation.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
