Description

Technical Field

[0001] The present invention relates to the technical field of filtering equipment, in particular to a large flow filtering equipment. Background Art

[0002] Filtration is the process of purifying fluids through special devices. There are many ways to filter, and the material systems used are also very wide. Solid-liquid, solid-gas, large particles, and small particles are all very common. In daily life, filtration equipment is needed to filter large flows of water.

[0003] In the application document of an intelligent filtering device proposed with application number 202211701157.8, a contact block is used to elastically lock the position of the blocking block to keep the opening unobstructed. When the impurities accumulated on the surface of the filter plate reach a limited level, the filter plate resistance booster moves, and the filter plate presses the contact block to release the blocking block to seal the opening. At this time, the liquid flow is stopped, which facilitates the disassembly and cleaning of the filter plate and realizes automatic detection of the permeability of the filter plate.

[0004] However, the liquid flow needs to be stopped during the cleaning process, resulting in poor continuity in the use of the filtration equipment. In addition, the filter is fixed during use, which causes impurities to easily adhere to the surface of the filter during the filtration process, thereby causing the filter to be blocked, affecting the use of the filtration equipment.

[0033] Example 1

[0034] like Figures 1-6 and Figure 10 As shown, a large flow filtering device includes a filter box 1 and a return box 2. The return box 2 is installed at both ends of the top of the filter box 1 by screws. A filter assembly 3 is installed inside the filter box 1. The filter assembly 3 includes a filter element 301, a rotating shaft 302, turbine blades 303, a cleaning element 304, a removal assembly 305, a dust box 306 and a cutting assembly 307.

[0035] A filter element 301 is installed inside the filter box 1, and a rotating shaft 302 is rotatably connected to the middle of one end of the filter box 1. A turbine blade 303 is fixedly sleeved on the outside of the rotating shaft 302, and a cleaning piece 304 is installed at the end of the rotating shaft 302. A removal component 305 is provided inside the filter box 1 near one end of the filter element 301, and a dust outlet box 306 is installed at the bottom of the filter box 1 by screws. A cutting component 307 is provided at the other end of the filter box 1.

[0036] After the water flows into the filter box 1, it is filtered by the filter assembly 3. After filtering, the water impacts the turbine blades 303, causing the turbine blades 303 to rotate, thereby realizing the rotation of the rotating shaft 302, realizing the operation of the cleaning element 304, and then realizing the cleaning of the filter element 301. When the filter element 301 is blocked, the end of the return box 2 is opened, and the impurities inside the filter box 1 are removed by the removal assembly 305, so that the impurities enter the dust box 306 and are collected and processed. The rotation of the rotating shaft 302 also drives the cutting assembly 307 to rotate, cutting and processing large impurities in the water flow, avoiding the large impurities being adsorbed on the filter assembly 3, causing the problem of inconvenience in cleaning the filter assembly 3, and also facilitating the discharge of impurities, avoiding the impurities accumulating inside the filter box 1 and the dust box 306, and affecting the water filtration.

[0037] A discharge valve is fixedly connected to the bottom of the dust box 306, and a transparent plastic plate is fixedly installed at one end of the filter box 1, which is convenient for personnel to observe and handle the moving position of the removal component 305 and to discharge impurities from the inside of the dust box 306.

[0038] The filter element 301 includes a return spring telescopic column 3011, a barrier filter 3012, a sealing plate 3013 and a backflow filter 3014;

[0039] The filter box 1 is evenly installed with return spring telescopic columns 3011 through screws, and one end of multiple return spring telescopic columns 3011 is connected through a blocking filter 3012. A closing plate 3013 is installed at one end of the blocking filter 3012 through screws, and a return filter 3014 is installed inside one end of the return box 2 through screws.

[0040] Water outlets are provided at both ends of the filter box 1 corresponding to the filter assembly 3. The closing plate 3013 corresponds to the water outlet at one end. The longitudinal section of the blocking filter 3012 is L-shaped. The bottom surface of the blocking filter 3012 is in contact with the bottom surface of the filter box 1, which facilitates the sealing of one end of the reflux box 2.

[0041] The water flow is filtered through the barrier filter 3012, and as the water flow is filtered, impurities will be distributed at one end of the barrier filter 3012, causing the barrier filter 3012 to be blocked. After the barrier filter 3012 is blocked, the water flow will push the barrier filter 3012 to move, thereby driving the closing plate 3013 to move, opening the return box 2, and allowing the water flow to be filtered through the return box 2, thereby achieving continuous filtration of the water flow.

[0042] The cleaning member 304 includes a return pipe 3041, a spring-driven telescopic rod 3042, a water outlet pipe 3043, a backflush pipe 3044, a cleaning brush 3045, a bidirectional bevel gear connection mechanism 3046, a rotating shaft 3047, a cam 3048, and a push rod 3049;

[0043] One end of the two return boxes 2 is connected by a return pipe 3041, and one end of the return pipe 3041 is rotatably connected to a rotating shaft 302, and one end of the rotating shaft 302 is fixedly connected to a spring telescopic rod 3042, and one end of the spring telescopic rod 3042 is connected to a water outlet pipe 3043 through a one-way valve. Four backflush pipes 3044 are evenly installed on the outside of the water outlet pipe 3043 through screws, and a cleaning brush 3045 is installed on one end of the water outlet pipe 3043 through screws. A two-way bevel gear connecting mechanism 3046 is provided on the outside of one end of the rotating shaft 302, and both ends of the two-way bevel gear connecting mechanism 3046 are fixedly connected to a rotating shaft 3047, and a cam 3048 is fixedly sleeved on the outside of one end of the rotating shaft 3047. The rotating shaft 3047 is rotatably connected to the inside of the filter box 1, and push rods 3049 are installed on both ends of one side of the blocking filter 3012 through screws.

[0044] The return pipe 3041 includes a guide frame and a water pipe. A guide frame is installed inside one end of the return box 2 by screws. The bottoms of the two guide frames are connected by a water pipe. The water pipe is rotatably connected to the rotating shaft 302 to realize the recycling of water flow without affecting the use of the rotating shaft 302. The rotating shaft 302 and the middle part of the spring telescopic rod 3042 are both provided with water outlet holes to facilitate the water flow to enter the backflush pipe 3044, thereby facilitating the backwashing of the water flow.

[0045] The backflushing pipe 3044 and the cleaning brush 3045 are arranged in an alternating manner, and the end of the cleaning brush 3045 is in contact with the barrier filter 3012 , so as to facilitate the cleaning of the barrier filter 3012 .

[0046] The bidirectional bevel gear connection mechanism 3046 includes three driving bevel gears. A driving bevel gear is fixedly sleeved on the outside of the rotating shaft 302. One end of the two rotating shafts 3047 is fixedly connected to a driving bevel gear. The driving bevel gear on the outside of the rotating shaft 302 is meshed with the driving bevel gears at one end of the two rotating shafts 3047. The rotation of the rotating shaft 302 is realized by the rotation of the rotating shaft 3047, thereby realizing the rotation of the cam 3048.

[0047] The positions of the cam 3048 and the push rod 3049 correspond to each other. The end of the push rod 3049 is provided with an arc angle to facilitate the push rod 3049 to move back and forth, thereby achieving vibration treatment of the isolation filter 3012 and cleaning of the isolation filter 3012.

[0048] When filtering the water flow, the filtered water flow impacts the turbine blades 303, driving the turbine blades 303 to rotate, and the rotation of the turbine blades 303 drives the spring telescopic rod 3042 to rotate, and the rotation of the spring telescopic rod 3042 drives the water outlet pipe 3043 to rotate, thereby realizing the rotation of the cleaning brush 3045, and the squeezing force of the spring telescopic rod 3042 drives the cleaning brush 3045 to move, so that the cleaning brush 3045 contacts the blocking filter 3012, and the rotation of the cleaning brush 3045 can clean the blocking filter 3012 to avoid blocking. The filter 3012 is blocked quickly due to its use, so the service life of the barrier filter 3012 can be extended. As the impurities at the end of the barrier filter 3012 gradually increase, the pressure on the water inlet end of the barrier filter 3012 increases, pushing the barrier filter 3012 to move, driving the push rod 3049 to move, and when the rotating shaft 302 rotates, the connection of the two-way bevel gear connection mechanism 3046 can drive the rotating shaft 3047 to rotate, and the rotation of the rotating shaft 3047 realizes the rotation of the cam 3048. When rotating, the push rod 3049 is intermittently driven to move, thereby pushing the barrier filter 3012 to move back and forth, causing the barrier filter 3012 to vibrate. When there are many impurities at the end of the barrier filter 3012, the barrier filter 3012 can be vibrated to further clean the barrier filter 3012, thereby ensuring the permeability of the barrier filter 3012 and thus ensuring the operation of the filtering device. As impurities accumulate, when there are many impurities at the end of the barrier filter 3012, the barrier filter 3012 moves and drives the closing plate 3013 to move. Move and open the return box 2. At this time, due to the large amount of impurities at the end of the filter box 1 and the low fluidity of the water flow, the water will flow into the return box 2 and filter the impurities through the return filter 3014. After the return water flows into the return pipe 3041, it drives the spring telescopic rod 3042 and the outlet pipe 3043, and then is sprayed out through the backflush pipe 3044 to backwash the barrier filter 3012, and remove the impurities adhering to the surface of the barrier filter 3012, thereby ensuring the filterability of the barrier filter 3012 and facilitating the subsequent filtering of the water flow.

[0049] Example 2

[0050] Based on the first embodiment, Figure 3 , pictures and Figure 8As shown, the removal assembly 305 includes a rotating blade 3051, a connecting shaft 3052, a first connecting driving member 3053, a double threaded rod 3054, a cleaning spring telescopic rod 3055, a pushing plate 3056, a pushing spring telescopic column 3057 and a counterflow plate 3058;

[0051] A rotating blade 3051 is rotatably connected inside the return box 2, and the two rotating blades 3051 are connected by a connecting shaft 3052. A connecting drive member 3053 is connected to the middle of the connecting shaft 3052. A double threaded rod 3054 is rotatably connected to one end of the filter box 1. The double threaded rod 3054 is fixedly connected to one end of the connecting drive member 3053. A cleaning spring telescopic rod 3055 is threadedly connected to the outside of the double threaded rod 3054. A push plate 3056 is installed at one end of the cleaning spring telescopic rod 3055 by screws. Push spring telescopic columns 3057 are evenly installed inside the dust outlet box 306 by screws, and the tops of several push spring telescopic columns 3057 are connected by a counterflow plate 3058.

[0052] The connecting drive member 3053 includes a one-way bevel gear connecting mechanism and a first belt connecting mechanism. A one-way bevel gear connecting mechanism is provided on the outer side of the middle part of the connecting shaft 3052. The one-way bevel gear connecting mechanism is connected to the first belt connecting mechanism through a circular shaft. The double threaded rod 3054 is fixedly connected to the first belt connecting mechanism to facilitate the rotation of the double threaded rod 3054.

[0053] A guide block is welded to one end of the reflux box 2 near the rotating blade 3051 to facilitate the rotation of the rotating blade 3051 and further facilitate the rotation of the double threaded rod 3054.

[0054] The cleaning spring telescopic rod 3055 includes a moving cylinder, a limiting column, a tension spring and a moving cleaning rod. The outer side of the double threaded rod 3054 is connected to the moving cylinder through a thread. Tension springs are welded at both ends of the inside of the moving cylinder. A limiting column is arranged inside the tension spring. The limiting column is fixedly connected to the inside of the moving cylinder. A moving cleaning rod is slidingly connected to the inside of the moving cylinder. The mobile cleaning rod is fixedly connected to the tension spring. An inclination angle is provided at the end of the mobile cleaning rod. The end of the mobile cleaning rod is in contact with the isolation filter 3012, so that the mobile cleaning rod can always be in contact with the end face of the isolation filter 3012, which is convenient for cleaning impurities in the isolation filter 3012, and can drive the impurities to move, thereby realizing the collection and treatment of impurities.

[0055] The end face of the push plate 3056 is in the same horizontal plane as one end face inside the dust box 306, one end of the counterflow plate 3058 is provided with an inclination angle, the bottom face of the double threaded rod 3054 is in the same horizontal plane as the bottom face inside the filter box 1, and the height of the push plate 3056 is greater than the height of one end of the counterflow plate 3058, which facilitates the entry of impurities into the dust box 306 and facilitates the limiting processing of the counterflow plate 3058.

[0056] The first magnetic rods are fixedly connected to both ends of the inside of the filter box 1 and both ends of the countercurrent plate 3058. Two adjacent first magnetic rods form a group. The two first magnetic rods in a group are adsorbed against each other. The bottom surface of the push plate 3056 and one end of the top of the push plate 3056 are fixedly connected to the second magnetic rods. The two second magnetic rods are adsorbed against each other. The adsorption force of the two second magnetic rods is greater than the adsorption force of the two first magnetic rods, thereby enhancing the connectivity between the countercurrent plate 3058 and the filter box 1 and ensuring the stability of the countercurrent plate 3058. When the push plate 3056 moves upward, it can drive the countercurrent plate 3058 to move upward, so that after the first magnetic rod is adsorbed, the two second magnetic rods can be separated from each other as the push plate 3056 moves upward.

[0057] When there are many impurities at the end of the filter box 1, the water flow will enter the return box 2 and impact and push the rotating blade 3051 to rotate. The rotation of the rotating blade 3051 drives the connecting shaft 3052 to rotate, and the connection of the connecting driving member 3053 drives the double threaded rod 3054 to rotate. The rotation of the double threaded rod 3054 drives the cleaning spring telescopic rod 3055 to move, thereby cleaning the impurities at the end of the blocking filter 3012 and pushing the impurities to move. As the cleaning spring telescopic rod 3055 moves, it drives the pushing plate 3056 to move. When the pushing plate 3056 pushes the counterflow plate 3058, the pushing spring telescopic column 3057 is compressed. At this time, the cleaning spring telescopic rod 3055 is stretched, so that the moving cleaning rod is always at the blocking filter 301 2 end faces are in contact, and the end face of the pushing plate 3056 is in contact with the end face of the dust box 306. At this time, the impurities are in the space between the cleaning spring telescopic rod 3055 and the pushing plate 3056 and will not leak. With the push of the counterflow plate 3058, the impurities move along the counterflow plate 3058. When a gap is generated between the counterflow plate 3058 and the filter box 1, the impurities enter the dust box 306 from the gap. The impurities are collected and processed to ensure the smooth filtration of the filter box 1. No manual cleaning is required, which reduces the labor intensity of the personnel. When the bottom surface of the pushing plate 3056 is higher than the height of the bottom surface of the filter box 1, the counterflow plate 3058 is reset to block the impurities inside the dust box 306, avoiding the problem of impurities entering the filter box 1 again.

[0058] like Figure 3 and Figure 10 As shown, the cutting assembly 307 includes a driving connector 3071, a driving shaft 3072 and a cutting blade 3073;

[0059] One end of the rotating shaft 3047 is fixedly connected to a driving connector 3071 , both ends of one side of the driving connector 3071 are fixedly connected to a driving shaft 3072 , and the outer sides of the driving shaft 3072 are fixedly connected to a cutting blade 3073 .

[0060] The driving connection 3071 includes a second belt connecting mechanism and two driving gears. One end of the rotating shaft 3047 is fixedly connected to the second belt connecting mechanism. One end of the filter box 1 is rotatably connected to the two driving gears. The two driving gears are meshed and connected. The two driving shafts 3072 are respectively fixedly connected to the two driving gears. The cutting knives 3073 on the two driving shafts 3072 are staggered, which is convenient for cutting impurities and driving the cutting knives 3073 to rotate.

[0061] When the turbine blades 303 rotate, the rotating shaft 3047 is driven to rotate. At this time, the driving shaft 3072 is driven to rotate through the connection of the driving connector 3071, and then the cutting knife 3073 is driven to rotate, cutting the impurities to make the impurities smaller, avoiding large impurities from being adsorbed on the surface of the barrier filter 3012, causing the barrier filter 3012 to be blocked and difficult to clean.

[0062] After water flows into one end of the filter box 1, it is filtered through the barrier filter 3012 and the filtered water is discharged from the other end of the filter box 1. When the water flows out, the turbine blades 303 are driven to rotate. When the turbine blades 303 rotate, the cleaning brush 3045 is driven to rotate to clean the barrier filter 3012. As the impurities at the end of the barrier filter 3012 increase, due to the faster flow rate of the water, the water flow will increase the pressure on the barrier filter 3012, pushing the barrier filter 3012 to move. When the turbine blades 303 are driven to rotate, the cam 3048 is driven to rotate synchronously. When the barrier filter 3012 moves to a certain position, the cam 3048 will contact the push rod 3049, causing the barrier filter 3012 to vibrate, further cleaning the barrier filter 3012, ensuring the permeability of the barrier filter 3012, and thus ensuring the filtration of the water flow, when the impurities increase again At this time, due to the obstruction of impurities at the end of the filter box 1, the barrier filter 3012 will gradually move to open the reflux box 2, and the water flow enters the impact rotating blade 3051 to rotate, thereby realizing the movement of the double threaded rod 3054, driving the cleaning spring telescopic rod 3055 and the push plate 3056 to move, opening the dust box 306, allowing impurities to enter the dust box 306, and collect and process the dust box 306, ensuring the filtering effect and efficiency of the filter box 1 on the water flow, ensuring the use of the filtering equipment, and eliminating the need for manual cleaning by personnel, reducing the labor intensity of personnel. In this process, the water flow will form a backwash effect, further cleaning the barrier filter 3012, and in the filtering process, the cutting knife 3073 will also rotate accordingly, and in the process of cutting impurities, the impurities will become smaller, avoiding large impurities from being adsorbed on the surface of the barrier filter 3012, causing the barrier filter 3012 to be blocked and inconvenient to clean.
