Abstract
The utility model discloses a large cathode frame of an electric dust removal device. The large cathode frame comprises a hanging beam and a frame body, wherein the hanging beam comprises cross beams, vertical beams, inclined ribs and two hanging pieces; the two hanging pieces are arranged on two ends of the cross beams; the whole hanging beam is welded and fixed in advanced in a workshop; the frame body comprises supporting beams, vertical beams A, inclined ribs A ad horizontal connecting pieces; and the frame body is welded on the hanging beam. As the large cathode frame is adopted, only four hanging points are arranged in a cathode system in each power supply area, so that the number of the hanging points is small, the stability of device operation can be improved, and the direct cost and the on-site installation and maintenance amount can be reduced.
Description
Technical field
The utility model relates to a kind of electric cleaner, relates in particular to a kind of negative electrode big frame of electric cleaner.
Background technology
Electric cleaner is that a kind of highfield that utilizes makes gas ionization, namely produces corona discharge, and then makes dust charged, and under the effect of electric field force, the dust arrester that dust is separated from gas.Electric cleaner comprises deduster body and power supply transformation fairing.Comprise sparking electrode (negative electrode), collecting electrode (anode), vibration body, airflow distribution device, high-voltage insulating system, shell and ash bucket etc. in the body.Mainly comprise following complexity and mutual relevant physical process with the suspension grit in the method divided gas flow of electric precipitation: apply high voltage, it is strong to produce high field, makes gas ionization, and produces the corona discharge electrode discharge; Suspension grit charged; Charged grit moves to electrode under the electric field force effect; Charged grit is captured in electric field; Vibration dust-cleaning.
At present, in the domestic more common cathode construction, big small frame split-type structural is a kind of typical cathode construction.The negative electrode small frame generally is made up of steel framework, support, rapping anvil etc., and the negative electrode big frame is made up of backbar, vertical beam and other auxiliary reinforcement diagonal brace.Each is arranged small frame and links to each other with big frame with connecting elements by support, by the negative electrode suspension apparatus in the incubator big frame is hung in electric field.Arrange big frame before and after the cathod system of single power supply zone, the big frame principal plane is vertical with airflow direction.For the less electric cleaner of sectional area, the cathod system of single power supply zone is hung by 4 groups of negative electrode erectings by overhang; For sectional area bigger electric cleaner, in the prior art, common way be big frame is divided into about two sections, every section is adopted 2 point of suspension, the cathod system that is single power supply zone adopts 8 groups of negative electrode erectings by overhang to hang, and fixes also spacing by connecting channel-section steel between the negative electrode big frame of the one-sided left and right sides.Adopt 8 groups of negative electrode erectings by overhang to hang, though solved backbar stress deformation problem, reached the standards for safe use requirement of beam, but owing to increased sling point, cost is too high, and is less economical, hangs quantity simultaneously and increases and reduced the equipment reliability of operation.In addition, the negative electrode big frame is assembly unit at the scene all, and the flatness of whole big frame be cannot say for sure to demonstrate,prove.
In view of this, the inventor studies and improves electric cleaner negative electrode big frame, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of electric cleaner negative electrode big frame, relates in particular to a kind of negative electrode big frame that beam adopts the combined truss structure that suspends in midair.
For achieving the above object, technical solution of the present utility model is:
A kind of electric cleaner negative electrode big frame, comprise suspention beam and frame body, frame body is fixed on the suspention beam, frame body is made up of brace summer, vertical beam, diagonal bar and horizontal connecting elements, plural number brace summer and the mutual vertical fixing of plural vertical beam, the suspention beam is made up of crossbeam, vertical beam, diagonal bar and hanging piece, plural number vertical beam vertical fixing is between two parallel entablatures and sill, the plural number diagonal bar is fixed between the adjacent vertical beam with diagonal manner respectively and adjacent diagonal bar is fixed in the both sides of the same end of vertical beam, two hanging pieces are arranged at the entablature two ends, form two suspension centres.
Further, one group of secondary suspention beam is set at least on described frame body, is made up of two adjacent brace summers, the vertical beam that is fixed thereon and diagonal bar, the fixed form of diagonal bar is with the fixed form of suspention beam diagonal bar.
Further, described frame body is made up of two identical frameworks, and two frameworks are fixed with the suspention beam respectively, and two frameworks are connected and fixed by horizontal connecting elements.
In this negative electrode big frame, the suspention beam adopts the combined truss structure, and in the good whole delivery of workshop assembly welding, and then rigidity and the intensity of raising suspention beam, simultaneously, the flatness of negative electrode big frame also obtains sound assurance, be applied in sectional area bigger electric cleaner on the time, two negative electrode big frames are set before and after the single service area, suspension centre quantity, can be reduced to 4 groups from original 8 groups, improve the equipment reliability of operation greatly, reduce cost.
