Description
Technical field
The present invention relates to the cathod systems of electric precipitator, and in particular, to a kind of cathode of electric dust collector frame, it is particularly suitable
In the biggish electric precipitator of electric field span.
Background technique
Electric precipitator is the environmental protection equipment using dust in DC high voltage electric field purifying industrial smoke.Usually connect high straightening
The electrode of galvanic electricity cathode collects the electrode of dust receiving electrode or anode corona discharge electrode (also known as cathode) (anode must be grounded).Yin
Pole frame is the very important component part of cathode of electric dust collector system, is equipped with several corona polar lines above.Usual cathode
Frame is fabricated to rectangle frame with seamless steel pipe, and You Sigen cross bar and four vertical bars are welded；The left and right sides of rectangular frame
Frame shoulder respectively has a support, and they buckle and are mounted on the total bracket of cathode.
But more large-scale cathode of electric dust collector frame self weight is larger, and after runing time is longer, the cross bar of cathode frame
With certain dust stratification can be accumulated on vertical bar and corona polar line, especially cathode rapping device work it is abnormal when, corona discharge electrode
Dust stratification on line is even more serious, that is, usually said " cathode is loose " phenomenon occurs, as a result make the total weight of entire cathode frame
It is increasing, and entirely for cathode frame completely by two support load-bearing on its left and right side frame top, this will cause cathode frame
All cross bars are all bent downwardly, and become concave upright arch, i.e., tenesmus deformation is the most serious in the middle part of cross bar, and then are caused lateral
Deformation changes the spacing between corona polar line and anode plate, reduces the electric field working voltage of electric precipitator, efficiency of dust collection is substantially
Decline, then occurs electric field short trouble when serious, high voltage control cabinet switch trip, and electric precipitator is completely ineffective；If
Situation especially severe, then may cause that cathode of electric dust collector frame is whole to slide the major accidents such as collapse from the total bracket of cathode.
Therefore, urgent need, which will provide one kind, can effectively prevent cathode of electric dust collector frame bending deformation even entirety easily occur
It slides and collapses from the total bracket of cathode, improve the cathode of electric dust collector frame of electric precipitator safety in operation and stability.
Summary of the invention
The object of the present invention is to provide a kind of cathode of electric dust collector frames, and the cathode of electric dust collector frame structure is simple, group
Dress is convenient, can effectively avoid cathode of electric dust collector frame from bending deformation even whole slide from the total bracket of cathode easily occur and collapse
It collapses, substantially increases the safety and stability of electric precipitator operation.
To achieve the goals above, the present invention provides a kind of cathode of electric dust collector frames, including by four cross bars and five
The rectangle frame of root vertical bar composition；Cross bar is mutually perpendicular to and is in the same plane with vertical bar, and four cross bars are parallel to each other row
Column setting, five vertical bars are arranged parallel to each other setting；
Wherein, the longitudinal length of rectangle frame is divided into trisection by four cross bars, and five vertical bars are long by the transverse direction of rectangle frame
Degree is divided into 2:1:1:2, and wherein a vertical bar is located on the vertical center line of rectangle frame；
The upper section of outermost two vertical bars is to reinforce vertical bar and reinforcing to set that there are two for pacifying on vertical bar on rectangle frame
Fill the horizontal through hole of the support of cathode frame.
It is preferably located above the cross bar at the top of rectangle frame and is equipped with an arc-shaped reinforcing rod, arc-shaped reinforcing rod and square
Shape frame in the same plane and raises upward and both ends are mutually welded and fixed with cross bar.
Preferably, more perpendicular supports, more perpendicular support edges are equipped between arc-shaped reinforcing rod and cross bar at the top of rectangle frame
Horizontal direction is equidistantly arranged and both ends are welded and fixed with cross bar and arc-shaped reinforcing rod respectively.
Preferably, the first of direction to the both ends of third root cross bar and the junction of vertical bar are equipped with diagonal brace from top to bottom, tiltedly
The both ends of support are respectively welded on adjacent cross bar and vertical bar.
Preferably, the both ends of the 4th cross bar in direction and the junction of outermost two vertical bars are respectively formed from top to bottom
There are 45 ° of chamferings.
Preferably, cross bar and vertical bar are that the seamless steel pipe of same model makes.
Preferably, the intersection of cross bar and vertical bar passes through welded connecting.
Preferably, reinforce vertical bar to be made of double steel pipe chain intermittent weld.
Preferably, the length for reinforcing vertical bar is greater than 1/3 length of vertical bar and extends to side from top to bottom from rectangle arch
To second diagonal brace lower position.
According to the above technical scheme, the present invention is additionally arranged a vertical bar, effect master on the vertical center line of rectangle frame
If increase cathode frame among non-deformability because the middle position of cathode frame be easiest to occur deforming downwards it is curved
Bent phenomenon, although the reinforcement structures such as arc-shaped reinforcing rod and perpendicular support at the top of rectangle frame are to the resistance to deformation energy of entire cathode frame
Power is substantially improved, it is contemplated that since electric field span is larger, once the corona polar line dust stratification amount in cathode frame middle position is excessive,
It is also possible to metaboly occur, for the non-deformability of the entire cathode frame of General Promotion, so also needing to cathode frame
Middle position further strengthen processing, and this structure of the invention also helps maintenance personal and stops in electric precipitator
The fault point among electric field is overhauled after operation；Meanwhile it is two-tube for adding on the left and right side frame vertical bar top of rectangle frame
The reinforcement vertical bar structure (two-tube to be designed with two for installing the horizontal through hole of cathode frame support) of chain intermittent weld, and require it
Length is greater than longitudinal total length of rectangle frame described in one third, and extends respectively to from top to bottom that second diagonal brace lower end of number be simultaneously
With the diagonal brace weld connection, this is because the weight and all corona polar lines of entire cathode frame and its reinforcement structure and thereon
The total weight of area ash all leans on this to support at two, and bending due to overweight at support show often occurs in traditional single tube structure
As this double pipe structure provided by the invention had both considerably increased the mechanical strength at cathode frame fulcrum, in turn ensured rectangle
Frame top half one-third of the area is firm, also adds the non-deformability of second cross bar or even entire cathode frame.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
