Description

Technical Field

[0001] The utility model relates to the technical field of filter plate cleaning of filters, and in particular to a vibration driving device and a real-time self-cleaning system for filter cloth of a pressurized filter. Background Art

[0002] The pressurized filter in the prior art is limited by its design characteristics and exhibits key shortcomings when dealing with the dehydration of flotation clean coal, fine coal slime and various metal concentrates, as well as the solid-liquid separation problems in the chemical, light industry and environmental protection industries. First, since the filter cloth is easily blocked by fine particles during the filtering operation, the filter holes are blocked and the filtering efficiency decreases accordingly. In order to restore the air permeability of the filter cloth, it must be washed regularly, but due to the need to ensure the operating efficiency, the cleaning interval is set to be longer. As the cleaning cycle is extended, the slag adsorbed on the filter cloth will become more stubborn in the time period between the two cleanings, aggravating the blockage of the filter holes, further reducing the filtering efficiency, and damaging the performance of the filter cloth. In addition, the long cleaning interval setting causes the time required for each cleaning to be extended to more than 30 minutes. This has caused a significant reduction in the filtering working time of the equipment, indirectly affecting the overall processing capacity, and increasing the number of frequent starts and stops of the supporting equipment, which has an adverse effect on the service life and operating efficiency of the equipment.

[0045] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes

[0046] A vibration driving device 1 includes: a base 1-1 having a limiting protrusion 1-2; a sliding member 1-3 is slidably arranged on the base 1-1; a shifting block 1-4 is slidably arranged on the sliding member 1-3, and after the sliding member 1-3 slides, the sliding member 1-3 or the shifting block 1-4 abuts against the limiting protrusion 1-2; a vibrating member 2 is arranged on the shifting block 1-4 or the sliding member 1-3; one end of an elastic member 1-5 is arranged on the sliding member 1-3, and the other end is arranged on the shifting block 1-4, for providing a force to move the sliding member 1-3 and the shifting block 1-4 away from each other.

[0047] In this embodiment, the base 1-1 is designed with a specific limiting protrusion 1-2 structure for limiting the range of motion of the slider 1-3 and triggering the vibration action. The slider 1-3 is designed to slide smoothly on the base 1-1. The shift block 1-4 is slidably arranged on the slider 1-3 and moves with the slider 1-3. When the slider 1-3 slides to the limit position on the base 1-1, the slider 1-3 or the shift block 1-4 will contact the limiting protrusion 1-2 on the base 1-1, triggering the vibration action. The vibrating member 2 is directly mounted on the shift block 1-4 or the slider 1-3. With the movement of the shift block 1-4, the vibrating member 2 will apply vibration to the filter disc 3-4 assembly, which helps to accelerate the unloading speed of the filter cloth on the filter disc 3-4 and improve the filtering efficiency. One end of the elastic member 1-5 is fixed on the slider 1-3, and the other end is connected to the shift block 1-4. Its function is to provide the shift block 1-4 with an elastic force to move away from the slider 1-3 in a natural state. When the shift block 1-4 is subjected to force and contacts the limiting protrusion 1-2 and is compressed, the elastic member 1-5 accumulates energy; when the contact is released, the elastic member 1-5 releases energy, pushing the shift block 1-4 and the vibrating member 2 to return quickly and generate vibration, further promoting the unloading effect of the filter disc 3-4 assembly. In summary, this vibration driving device 1 achieves efficient vibration assistance to the filter disc 3-4 assembly through reasonable structural design and action coordination, effectively improving the filtration quality and working efficiency of the pressure filter.

[0048] Furthermore, it also includes: a gear 1-6 is rotatably set on the base 1-1; a rack 1-7 is set on the sliding member 1-3, the rack 1-7 is meshed with the gear 1-6, the gear 1-6 drives the rack 1-7 to slide back and forth, and after the rack 1-7 slides and abuts the limiting protrusion 1-2, the gear 1-6 is used to drive the shift block 1-4 to slide.

[0049] In this embodiment, a transmission structure of a gear 1-6 and a rack 1-7 is further added to achieve more accurate and effective drive control. Specifically, the vibration driving device 1 includes a base 1-1, a sliding member 1-3, a shifting block 1-4, a vibrating member 2, an elastic member 1-5, and a newly added gear 1-6 and rack 1-7 assembly. In addition to the original limiting protrusion 1-2 on the base 1-1, a gear 1-6 is also rotatably arranged. A rack 1-7 meshing with the gear 1-6 is installed on the sliding member 1-3. When the gear 1-6 rotates, through the meshing transmission, it can drive the rack 1-7 to make reciprocating linear motion along the sliding member 1-3.

[0050] In actual operation, when the gear 1-6 rotates and drives the rack 1-7 to slide, the movement of the rack 1-7 drives the sliding member 1-3 to move, wherein the teeth of the shifting block 1-4 and the rack 1-7 have the same structure, and when the sliding member 1-3 moves, the shifting block 1-4 moves to the position of the gear 1-6, and the shifting block 1-4 is shifted to make the shifting block 1-4 slide on the sliding member 1-3. When the sliding member 1-3 or the shifting block 1-4 contacts the limiting protrusion 1-2 on the base 1-1, the vibration drive of the vibrating member 2 is realized through the elastic action of the elastic member 1-5 and the shifting action of the gear 1-6.

[0051] For example, when the pressure filter is working, the gear 1-6 is driven to rotate through the external control system, and the gear 1-6 drives the rack 1-7 to slide. The reciprocating motion of the rack 1-7 makes the shift block 1-4 approach the gear 1-6. After contacting the gear 1-6, it slides on the sliding member 1-3 under the movement of the gear 1-6. When the shift block 1-4 or the sliding member 1-3 touches the limiting protrusion 1-2 of the base 1-1, the restoring force generated by the elastic member 1-5 will cause the shift block 1-4 to return instantly, thereby generating a vibration effect on the filter plate 3-4 assembly through the vibrating member 2, thereby effectively improving the filtration efficiency and unloading effect.

[0052] Furthermore, the base 1-1 has a slide rail 1-8, the sliding member 1-3 is slidably set in the slide rail 1-8, the limiting protrusions 1-2 are located at both ends of the sliding member 1-3, and also includes: a limiting rod 1-9 is set on the sliding member 1-3, after the sliding member 1-3 slides, the limiting rod 1-9 abuts against the limiting protrusion 1-2 on one side.

[0053] In this embodiment, a slide rail 1-8 is provided on the base 1-1, and the slide 1-3 is designed to slide freely in the slide rail 1-8 to ensure the smoothness and guidance of its movement. The limit protrusions 1-2 are located at both ends of the slide 1-3, which play a role in limiting the sliding range of the slide 1-3. A limit rod 1-9 is added to the slide 1-3. When the slide 1-3 slides to the extreme position along the slide rail 1-8, the limit rod 1-9 will contact the limit protrusion 1-2 at one end of the slide 1-3, thereby preventing the slide 1-3 from continuing to slide, ensuring that the slide 1-3 works within the specified stroke to avoid excessive impact or separation from the slide rail 1-8.

[0054] For example, during the operation of the pressure filter, when it is necessary to drive the vibrating member 2 to vibrate the filter disc 3-4, a motor is arranged on the base 1-1, and the motor drives the gear 1-6 to rotate, so that the sliding member 1-3 slides in the slide rail 1-8. When the sliding member 1-3 approaches the limiting protrusion 1-2, the limiting rod 1-9 will first contact and resist the limiting protrusion 1-2. At this time, the sliding member 1-3 or the shifting block 1-4 will generate a certain vibration amplitude. When the vibrating member 2 is located on the shifting block 1-4, the gear 1-6 shifts the shifting block 1-4 and the elastic member 1-5 resets the force, so that the vibrating member 2 generates a reciprocating vibration force, or when the vibrating member 2 is located on the sliding member 1-3, the gear 1-6 shifts the rack 1-7 and the elastic member 1-5 resets the force, so that the vibrating member 2 generates a reciprocating vibration force, thereby realizing the vibration auxiliary effect on the filter disc 3-4, effectively improving the filtering efficiency and the unloading effect.

[0055] A real-time self-cleaning system for filter cloth of a pressurized filter includes a vibration driving device 1, the vibration driving device 1 has one or more, and also includes: a frame 3-1; a filter cartridge 3-2 is arranged on the frame 3-1, and has a filling port 3-3, and a base 1-1 is arranged on the filter cartridge 3-2; there are a plurality of filter discs 3-4, which are arranged in the filter cartridge 3-2 and have a liquid outlet 3-5; the active end of a vibrating member 2 is located in the filter cartridge 3-2, and the vibrating member 2 abuts against or cancels the abutment against the filter disc 3-4 after moving.

[0056] In this embodiment, the system mainly consists of a frame 3-1, a filter cartridge 3-2, a filter disc 3-4 and one or more vibration-driving devices 1. Among them, the frame 3-1 serves as the supporting structure of the entire system, the filter cartridge 3-2 is fixedly mounted on the frame 3-1, and is provided with a filling port 3-3 for injecting slurry. A base 1-1 is provided on the outside of the filter cartridge 3-2 to ensure that the vibration-driving device 1 can be accurately installed on the filter cartridge 3-2. Several filter discs 3-4 are also arranged inside the filter cartridge 3-2, each filter disc 3-4 has its own liquid outlet 3-5, and each liquid outlet 3-5 is connected to the outside through a pipeline to facilitate the discharge of the filtered liquid. The key point is that when the vibrating member 2 in the vibration-driving device 1 is designed, its active end is located inside the filter cartridge 3-2.

[0057] During actual operation, the vibration driving device 1 controls the movement of the vibrating member 2 according to the requirements of the filtering process, so that it can abut or cancel the abutment of the filter disc 3-4 in a timely manner. When the vibrating member 2 contacts the filter disc 3-4, a vibration effect is generated, which can effectively help the fine particles adhering to the filter cloth to detach, reduce the probability of filter hole clogging, and achieve real-time self-cleaning of the filter cloth, thereby improving the filtering efficiency and the service life of the filter cloth. Through this structure and working method, the real-time self-cleaning system for the filter cloth of the pressurized filter of this embodiment can ensure that the filter cloth always maintains good filtering performance during the continuous operation of the filter, thereby improving the working efficiency of the overall equipment.

[0058] Furthermore, the vibrating member 2 includes: one end of the connecting rod 2-1 is arranged on the sliding member 1-3 or the shifting block 1-4, and is located outside the filter cartridge 3-2; there are a plurality of elastic telescopic members 2-2, which are arranged at intervals on the other end of the connecting rod 2-1; there are a plurality of vibrating members 2-3, which are correspondingly arranged on the elastic telescopic members 2-2, and one vibrating member 2-3 abuts or cancels abutment with one filter disc 3-4.

[0059] In this embodiment, the vibrating member 2 includes a connecting rod 2-1 and an elastic telescopic member 2-2. One end of the connecting rod 2-1 is connected to the sliding member 1-3 or the dial block 1-4, and the end is located outside the filter cartridge 3-2 to receive the motion command of the vibration driving device 1. The other end of the connecting rod 2-1 is equipped with a plurality of elastic telescopic members 2-2, and these elastic telescopic members 2-2 are arranged at a certain interval. A vibrating member 2-3 is correspondingly arranged at the top of each elastic telescopic member 2-2. When the vibration driving device 1 is working, the sliding member 1-3 drives the connecting rod 2-1 to move, and then the elastic telescopic member 2-2 causes the vibrating member 2-3 to reciprocate. During the movement of the vibrating member 2-3, a vibrating member 2-3 will timely abut or cancel the abutment with the corresponding filter disc 3-4, and remove the impurities on the surface of the filter disc 3-4 and the inside of the filter cloth through the vibration action, so as to realize the real-time self-cleaning of the filter cloth.

[0060] For example, in actual operation, when the vibration driving device 1 drives the sliding member 1-3 in the sliding rail 1-8 through the transmission of the gear 1-6 and the rack 1-7, the connecting rod 2-1 on the sliding member 1-3 moves accordingly, and then drives the vibration member 2-3 to perform regular oscillation movement inside the filter cartridge 3-2 through the elastic telescopic member 2-2. When the vibration member 2-3 contacts the filter disc 3-4, the blockage on the filter cloth will be loosened by vibration, thereby effectively improving the filtering performance of the filter cloth, increasing the filtering efficiency and the service life of the filter cloth.

[0061] Furthermore, it also includes: pressurization, which has a plurality of pressurized plates 3-6 that are spaced apart on the connecting rod 2-1 and are located in the filter cartridge 3-2. After the connecting rod 2-1 moves, it drives the pressurized plate 3-6 to approach or move away from the filter plate 3-4.

[0062] In this embodiment, the vibrating member 2 in the vibration driving device 1 is designed to include a connecting rod 2-1, an elastic telescopic member 2-2 and a vibrating member 2-3. One end of the connecting rod 2-1 is connected to the sliding member 1-3 or the dial block 1-4 and is located outside the filter cartridge 3-2, while the other end extends to the inside of the filter cartridge 3-2, and a plurality of pressure plates 3-6 are arranged at intervals on the connecting rod 2-1. These pressure plates 3-6 are staggered with the filter disc 3-4. When the connecting rod 2-1 moves with the sliding member 1-3, it can drive the pressure plate 3-6 to move closer to or away from the filter disc 3-4, thereby realizing the pressurization operation of the filter disc 3-4. In the actual working process, the vibration driving device 1 drives the sliding member 1-3 to slide in the slide rail 1-8 of the base 1-1, and the sliding member 1-3 drives the connecting rod 2-1 to move. The movement of the connecting rod 2-1 will not only vibrate and clean the filter disc 3-4 through the elastic expansion member 2-2 and the vibrating member 2-3, but also make the pressure plate 3-6 approach or move away from the filter disc 3-4. When the pressure plate 3-6 approaches the filter disc 3-4, the pressure on the filter cloth on the filter disc 3-4 can be increased, the filtering efficiency can be improved, and the problem of filter hole blockage can be effectively overcome. At the same time, combined with the vibration effect of the vibrating member 2, the double dynamic cleaning of the filter cloth can be achieved, ensuring that the filter can operate efficiently and stably.

[0063] Furthermore, there are several vibration driving devices 1, which are divided into two groups and are all arranged on the filter cartridge 3-2. The filter disc 3-4 is located between two adjacent pressure plates 3-6. The two groups of vibration driving devices 1 respectively drive the pressure plates on both sides of the filter disc 3-4 to slide. After the pressure plates 3-6 on both sides of the filter disc 3-4 slide, they move closer to or away from the filter disc 3-4.

[0064] In this embodiment, inside the filter cartridge 3-2 in the system, the filter disc 3-4 is reasonably placed between a plurality of pressure discs 3-6, with a filter disc 3-4 being arranged between every two adjacent pressure discs 3-6. The two sets of vibration-driving devices 1 are respectively responsible for driving the pressure discs 3-6 on both sides of the filter disc 3-4 to slide. When the filter is running, the two sets of vibration-driving devices 1 work synchronously, and through the meshing action of the gear 1-6 and the rack 1-7, the sliding member 1-3 slides in the slide rail 1-8 and drives the connecting rod 2-1 to move. The pressure disc 3-6 on the connecting rod 2-1 then approaches or moves away from the filter disc 3-4, applying an appropriate amount of pressure to the filter disc 3-4. At the same time, under the action of the elastic telescopic member 2-2, the vibrating member 2-3 will also abut or cancel the abutment against the filter disc 3-4 in a timely manner to perform oscillation cleaning.

[0065] In specific operation, for example, when one group of vibration driving devices 1 drives the pressure plate 3-6 on one side of the filter disc 3-4 to approach the filter disc 3-4, the other group of vibration driving devices 1 drives the pressure plate 3-6 on the other side of the filter disc 3-4 away from the filter disc 3-4. This can not only achieve effective pressurization of the filter disc 3-4 to improve the filtration efficiency, but also clean the filter cloth through the vibration of the vibrating piece 2, thereby forming a dynamic balance of alternating pressurization and vibration cleaning on both sides of the filter disc 3-4, greatly improving the real-time self-cleaning effect of the filter cloth and the overall working efficiency of the filter machine.

[0066] Further, the filter disc 3-4 is rotatably disposed in the filter cartridge 3-2.

[0067] Furthermore, the elastic telescopic member 2-2 is arranged on the connecting rod 2-1 through the pressure plate 3-6, and the vibrating member 2-3 is located in the upper half of the filter cartridge 3-2.

[0068] In this embodiment, it is worth noting that; slurry is poured into the filter cartridge 3-2 through the filling port 3-3, and the filled slurry is not higher than the horizontal center line of the filter cartridge 3-2. Specifically, when the pressure plate 3-6 is pressurized, its water level is not higher than the horizontal center line of the filter cartridge 3-2; after the filter disc 3-4 rotates, the vibrating member 2-3 can clean the filter screen in the upper part, and the lower part works normally. When the lower part needs to be cleaned, the filter disc 3-4 rotates to further clean the used part.

[0069] Furthermore, the vibrating member 2-3 includes: a plurality of supporting rods 2-3-1, all of which are arranged on the elastic telescopic member 2-2; and a plurality of cleaning protrusions 2-3-2, which are arranged at intervals on the supporting rod 2-3-1.

[0070] In this embodiment, a plurality of support rods 2-3-1 are designed and installed on the elastic telescopic member 2-2, and these support rods 2-3-1 are indirectly connected to the connecting rod 2-1 through the elastic telescopic member 2-2. When the vibration driving device 1 drives the connecting rod 2-1 to move, the power is transmitted to the elastic telescopic member 2-2 through the pressure plate 3-6, so that it produces a telescopic action, thereby driving the support rod 2-3-1 to perform corresponding movements. A plurality of cleaning protrusions 2-3-2 are arranged at intervals on each support rod 2-3-1, and the design purpose of these cleaning protrusions 2-3-2 is to directly contact the filter disc 3-4 or filter cloth in the filter cartridge 3-2. When the support rod 2-3-1 vibrates under the drive of the elastic telescopic member 2-2, the cleaning protrusion 2-3-2 will repeatedly contact and leave the surface of the filter cloth. Through this high-frequency, small-amplitude contact and separation action, the vibration and cleaning effect of fine particles on the surface of the filter cloth is achieved, thereby effectively preventing and solving the problem of filter cloth clogging and improving the filtering efficiency. The cleaning protrusion 2-3-2 can be a brush. During the specific operation, as the pressure plate 3-6 in the filter cartridge 3-2 approaches or moves away from the filter plate 3-4, and the elastic telescopic member 2-2 drives the support rod 2-3-1 to vibrate, the cleaning protrusion 2-3-2 continuously performs self-cleaning operations on the upper part of the filter cartridge 3-2, ensuring that the filter cloth always maintains good filtering performance.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
