Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and particularly to an efficient dust filtering equipment based on the combined action of high-density magnetic flux and spraying. Background Art

[0002] A dry electrostatic precipitator with a net plate composite anode plate, with the publication number of "CN109013059A" in the prior art, includes a housing, anode plates and corona wires. The anode plates and corona wires are both arranged in the housing. The anode plates and corona wires are arranged alternately and parallelly. An electric field is formed between the anode plates and the corona wires. A plurality of through holes are formed in the middle of the anode plates to form a hole plate area. Dust collection strengthening mechanisms are fixed on the left and right sides of the anode plates. The dust collection strengthening mechanisms include a front strengthening part protruding towards the front side of the anode plate and a rear strengthening part protruding towards the rear side of the anode plate. The weight of the entire anode plate of this device is greatly reduced, and the models of the support structures such as the steel brackets, housing, and cross beams of the entire electrostatic precipitator can also be reduced. The overall steel consumption, installation cost, and manufacturing cost of the electrostatic precipitator are all reduced. The transverse scouring effect of the ionic wind at the dust collection electrode plates is weakened. In the area directly opposite the corona wires under high voltage, the collection effect of fine dust is better than that of traditional electrode plates.

[0003] However, there are still relatively obvious defects in the use of the above device: The above device uses a fixed net plate structure for dust removal. Although it can achieve a good dust removal effect, this plate-type dust removal structure has a relatively single function, and the dust attached to it cannot be effectively cleaned. Moreover, the fixed dust removal structure cannot replace and supplement the net plate in a timely manner. When replacing and cleaning the net plate, it is necessary to stop the machine for processing, delaying the production progress. Summary of the Invention

[0004] The purpose of the present invention is to provide an efficient dust filtering equipment based on the combined action of high-density magnetic flux and spraying, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An efficient dust filtering equipment based on the combined action of high-density magnetic flux and spraying includes a number of chain plates. Assembly pin holes are correspondingly formed on the front and rear sides of the number of chain plates. By inserting chain belt pins into the assembly pin holes of adjacent chain plates, a number of chain plates are connected end to end to form a closed chain belt. Driving wheels and driven wheels are respectively arranged at both ends of the chain belt. Transmission teeth that engage with the chain plates are formed on both the driving wheels and the driven wheels.

[0007] The link plate is composed of a skeleton and a piezoelectric vibration module. A number of piezoelectric dust removal vibration units are arranged in the piezoelectric vibration module. Vibration grooves penetrating through the front and rear sides are formed in the piezoelectric dust removal vibration units. Piezoelectric ceramic sheets are fixedly installed in the vibration grooves. Elastic metal sheets are laminated and compounded on the upper and lower sides of the piezoelectric ceramic sheets. A dust filtering channel is also penetratingly formed in the middle of the piezoelectric ceramic sheet. Mesh dust filtering holes are formed in the elastic metal sheets corresponding to the positions of the dust filtering channels;

[0008] A number of elastic metal sheets arranged on the chain belt are connected in series and connected to the circuit of power supply module one. Power is supplied to the elastic metal sheets through power supply module one so as to generate a magnetic field around them, and then the flowing dust is charged and adsorbed on the elastic metal sheets;

[0009] Piezoelectric ceramic sheets on a number of the piezoelectric dust removal vibration units and the elastic metal sheets on both sides are also respectively connected in parallel to the circuit of power supply module two through wires. Power is supplied to the piezoelectric ceramic sheets and the elastic metal sheets through power supply module two to generate the inverse piezoelectric effect, prompting the surface of the elastic metal sheets to vibrate, and the dust attached to the elastic metal sheets to fall off through the vibration;

[0010] A spray head is also arranged on the flow path of the link plate. The atomized water ejected by the spray head is used to clean the dust attached to the elastic metal sheets.

[0011] Preferably, a number of the piezoelectric dust removal vibration units are detachably installed on the skeleton. A drag plate for supporting the piezoelectric dust removal vibration units is fixedly installed at the bottom of the skeleton. Assembly holes are formed in both the drag plate and the piezoelectric dust removal vibration units. The piezoelectric dust removal vibration units and the drag plate are fixedly connected by inserting bolts into the assembly holes.

[0012] Preferably, a strip-shaped grid filter plate is also movably arranged above the piezoelectric dust removal vibration units of the link plate. A number of strip-shaped grid filter plates arranged on the chain belt are connected in series and connected to the circuit of power supply module one. Power is supplied to the strip-shaped grid filter plates through power supply module one so as to generate a magnetic field around them, and then the flowing dust is charged and adsorbed on the strip-shaped grid filter plates.

[0013] Preferably, the strip-shaped grid filter plate is connected to the skeleton through elastic traction lines arranged at the four corners, so that the strip-shaped grid filter plate is movably arranged above the piezoelectric dust removal vibration units.

[0014] Preferably, a number of rubber vibration rods are also fixedly installed on the elastic metal sheets close to one side of the strip-shaped grid filter plate. The rubber vibration rods are all movably abutted against the strip-shaped grid filter plate on the side far away from the elastic metal sheets. During the vibration of the elastic metal sheets, the vibration is conducted to the strip-shaped grid filter plate through the rubber vibration rods.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The chain belt type dust removal mechanism provided by the present invention can replace the chain plates in time as needed, ensuring that the normal dust removal operation is not affected during the replacement process. In addition, the present invention designs a unique dust removal structure. The dust is adsorbed by the charged elastic metal sheet, and further, the inverse piezoelectric effect of the elastic metal sheet and the piezoelectric ceramic sheet is utilized to generate high-frequency vibration, so as to promote the dust attached to the elastic metal sheet to fall off, playing a dual role of dust interception and promoting dust shedding.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1-7 , the present invention provides a technical solution:

[0027] Embodiment 1:

[0028] An efficient dust filtering device based on the combined action of high-density magnetic flux and spraying, comprising a plurality of chain plates 1. Assembly pin holes 2 are correspondingly formed on the front and rear sides of the plurality of chain plates 1. By inserting chain belt pins into the assembly pin holes 2 of adjacent chain plates 1, the plurality of chain plates 1 are connected end to end to form a closed chain belt 3. A driving wheel 4 and a driven wheel 5 are respectively arranged at both ends of the chain belt 3. Transmission teeth engaged with the chain plates 1 are formed on both the driving wheel 4 and the driven wheel 5;

[0029] The chain plate 1 is composed of a framework 6 and a piezoelectric vibration module 7. A plurality of groups of piezoelectric dust removal vibration units 8 are arranged in the piezoelectric vibration module 7. A vibration groove 9 penetrating through the front and rear sides is formed in the piezoelectric dust removal vibration unit 8. A piezoelectric ceramic sheet 10 is fixedly installed in the vibration groove 9. Elastic metal sheets 12 are laminated and compounded on the upper and lower sides of the piezoelectric ceramic sheet 10. A dust filtering channel 11 is also formed through the middle of the piezoelectric ceramic sheet 10. Mesh dust filtering holes 13 are formed at the positions of the elastic metal sheets 12 corresponding to the dust filtering channel 11;

[0030] A plurality of elastic metal sheets 12 arranged on the chain belt 3 are connected in series and connected to the circuit of a power supply module 14. By supplying power to the elastic metal sheets 12 through the power supply module 14, a magnetic field is generated around them, and thus the flowing dust is charged and adsorbed on the elastic metal sheets 12;

[0031] The piezoelectric ceramic sheets 10 on the plurality of piezoelectric dust removal vibration units 8 and the elastic metal sheets 12 on both sides are also respectively connected in parallel to the circuit of a power supply module 15 through wires. By supplying power to the piezoelectric ceramic sheets 10 and the elastic metal sheets 12 through the power supply module 15, an inverse piezoelectric effect is generated, prompting the surface of the elastic metal sheets 12 to vibrate, and the dust attached to the elastic metal sheets 12 is shaken off through the vibration;

[0032] A spray head 16 is also arranged on the flow path of the chain plate 1. The atomized water sprayed by the spray head 16 is used to clean the dust attached to the elastic metal sheets 12.

[0033] In this embodiment, the combination of the chain plates 1 and the driving method using the driving wheel 4 and the driven wheel 5 are common chain plate 1 driving methods in the prior art. By applying a rotating force to the driving wheel 4, a plurality of chain plates 1 can be driven to reciprocate. In actual use, the chain belt 3 composed of a plurality of chain plates 1 is rotated and replaced once at a set time. Different from the prior art, the chain plate 1 in this embodiment is composed of a skeleton 6 and a piezoelectric vibration module 7. The piezoelectric vibration module 7 is provided with a plurality of groups of piezoelectric dust removal vibration units 8. The dust removal vibration unit 8 is provided with a piezoelectric ceramic sheet 10 and an elastic metal sheet 12, wherein a dust filter channel 11 is provided in the middle of the piezoelectric ceramic sheet 10, through which the airflow can flow from one side of the chain plate 1 to the other side, and the elastic metal sheet 12 is provided with a mesh dust filter hole 13 corresponding to the position of the dust filter channel 11, and the mesh dust filter hole 13 is used to intercept dust. In this embodiment, a plurality of elastic metal sheets 12 are connected in series and connected to the circuit of the power supply module 14, and the power supply module 14 supplies power to the elastic metal sheet 12. Power is supplied to generate a magnetic field around it, so that the dust flowing through is charged and adsorbed on the elastic metal sheet 12. In addition, the elastic metal sheet 12 is also combined with the piezoelectric ceramic sheet 10 to form a piezoelectric unit. By supplying power to the elastic metal sheet 12 and the piezoelectric ceramic sheet 10, an inverse piezoelectric effect is generated, which in turn causes the surface of the elastic metal sheet 12 to generate high-frequency vibrations. The advantage of this design is that the elastic metal sheet 12, on the one hand, serves as an adsorption mechanism for dust. When the elastic metal sheet 12 is powered on, a circular magnetic field will be formed around the elastic metal sheet 12. For the surrounding dust, if the dust particles are charged, the magnetic field can interact with the charge to generate a Lorentz force, thereby indirectly affecting the movement trajectory of the dust and making it easier to be adsorbed. On the other hand, the elastic metal sheet 12 is also a component unit of the inverse piezoelectric effect. The high-frequency vibration generated by the inverse piezoelectric effect causes the adsorbed dust to detach from the elastic metal sheet 12. This is the technical point in this embodiment. The applicant has cleverly used the metal sheet to achieve multiple effects in capturing and removing dust, and has outstanding substantial characteristics.

[0034] Embodiment 2:

[0035] Several groups of piezoelectric dust removal vibration units 8 are detachably mounted on the frame 6, and a drag plate 17 for supporting the piezoelectric dust removal vibration units 8 is fixedly mounted at the bottom of the frame 6. Assembly holes 18 are provided on the drag plate 17 and the piezoelectric dust removal vibration units 8, and bolts are inserted into the assembly holes 18 to complete the fixed connection between the piezoelectric dust removal vibration units 8 and the drag plate 17.

[0036] In this embodiment, the piezoelectric dust removal vibration unit 8 adopts a modular design and is detachably mounted on the frame 6. The design of multiple groups of piezoelectric dust removal vibration units 8 facilitates subsequent maintenance and replacement, thereby reducing the cost of replacement.

[0037] Embodiment III:

[0038] Above the chain plate 1 and also movably arranged above the piezoelectric dust removal vibration unit 8 is a strip-shaped grid filter plate 19. A number of strip-shaped grid filter plates 19 arranged on the chain belt 3 are connected in series and connected to the circuit of the first power supply module 14. Power is supplied to the strip-shaped grid filter plate 19 through the first power supply module 14 to generate a magnetic field around it, so that the flowing dust is charged and adsorbed on the strip-shaped grid filter plate 19.

[0039] The strip-shaped grid filter plate 19 is connected to the skeleton 6 through elastic traction lines 20 arranged at the four corners, so that the strip-shaped grid filter plate 19 is movably arranged above the piezoelectric dust removal vibration unit 8.

[0040] A number of rubber vibrating rods 21 are also fixedly installed on the elastic metal sheet 12 close to the strip-shaped grid filter plate 19. One sides of the number of rubber vibrating rods 21 away from the elastic metal sheet 12 are movably abutted against the strip-shaped grid filter plate 19. During the vibration process, the elastic metal sheet 12 conducts the vibration to the strip-shaped grid filter plate 19 through the rubber vibrating rods 21.

[0041] In this embodiment, a strip-shaped grid filter plate 19 is further installed on the chain plate 1 and powered by the first power supply module 14, so as to produce the same dust adsorption effect as the elastic metal sheet 12. The area of this dust adsorption is larger, so that dust can be adsorbed more comprehensively. And the strip-shaped grid filter plate 19 and the elastic metal sheet 12 are combined to form a double-layer dust adsorption mechanism, which can improve the capture rate of dust. In addition, the strip-shaped grid filter plate 19 is also connected to the elastic metal sheet 12 through the rubber vibrating rods 21. During the high-frequency vibration of the elastic metal sheet 12, the strip-shaped grid filter plate 19 is synchronously driven to vibrate, so as to promote the dust on its surface to fall off. Further cooperating with the spraying mechanism in Embodiment I, the dust removal operation can be better realized.

[0042] The specific steps of dust adsorption and dust cleaning are as follows:

[0043] First, turn on the power supply module 14 to supply power to the strip grille filter plate 19 and the elastic metal sheet 12, so as to use one side link plate 1 on the chain belt 3 to perform the dust adsorption operation. After the dust on one side is adsorbed, control the driving wheel 4 and the driven wheel 5 to work so that the link plate 1 on the other side is adjusted to the position for dust adsorption. After the link plates 1 on both sides are adsorbed, disconnect the circuit of the power supply module 14. At this time, turn on the circuit of the power supply module 15 so that high-frequency vibration is generated on the surface of the strip grille filter plate 19 and the elastic metal sheet 12, thereby prompting the attached dust to fall off. At the same time, turn on the spray device to knock down the dust and realize the cleaning of the entire chain belt 3. After the cleaning is completed, dry the surface of the chain belt 3. After the drying is completed, prepare for the next dust filtration work.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
