Abstract
The utility model discloses a wreathed cathode line which is used by an electric precipitator and is anti-extension. The utility model comprises wreathed steel bars which are thicken correctly and concrete iron holes bent by the concrete iron, wherein the steel bars are provided with a plurality of adjustable arcs which are capable of being used for canceling out stretching tensor caused by thermal expansion and cooling, two ends of the steel bars are provided with bends of 90 DEG, as optimization, amount of adjustable arcs arranged on the steel bars is two, and the two adjustable arcs are respectively positioned near the two ends of the steel bars. The bends of 90 DEG of the wreathed steel bars are capable of being inserted directly in the concrete iron holes, and the end portions are curved and fixed, thereby non-fracture of the wreathed steel bars in the process of use can be ensured. The utility model has the advantages of safety, reliability and convenient erection and maintenance, and is adapted to the wreathed cathode line arranged on the electric precipitator.
Description
Technical field
The utility model relates to a kind of electric cleaner, relates in particular to a kind of twist shape cathode line that is used on the electric cleaner.
Background technology
The cathode line kind of using on the electric cleaner is not following tens kinds at present, as the zigzag cathode line, the spirality cathode line, twist shape cathode line (hereinafter to be referred as twistedwire), the star-type cathode line, tubular barbed wire etc., wherein twistedwire appearance and size is less, generally have only about 4 * 4mm, thereby production cost is lower, and has an electric field breakdown voltage height, discharge evenly, characteristics such as easy for installation, but common twistedwire is because the linear tiny intensity that causes, rigidity is lower, thereby break easily, and when installing adopt twistedwire two ends with brazing burn-on the M5 screw rod add nut again with modes such as cathode frame is fixing, because operating personnel stand on the cathode frame, the human body weight effect causes that the cathode frame distortion causes the damage or the fracture of twistedwire easily during installation; Because the twistedwire employing is installed perpendicular to the cathode frame base, after twistedwire and cathode frame are fixing, when the measures of dispersion of expanding with heat and contract with cold of cathode frame and twistedwire is excessive, the twistedwire fracture takes place easily also on the other hand.Because the reliability of cathode line is directly connected to the normal operation of electric cleaner, and the repairing of electric cleaner inside must just can be carried out when boiler shutdown, and a maintenance intervals time is longer, therefore the reliability requirement of target line is very high, so the deficiency of twistedwire and defective badly influence applying of twistedwire.Environmental protection industry (epi) presses for a kind of existing good cathode line that discharge effect, production cost are lower, reliability is high at present.
The utility model content
The technical problems to be solved in the utility model provides a kind of electric cleaner safe and reliable, convenient for installation and maintenance with resisting flexible twist shape cathode line.
The utility model is achieved through the following technical solutions:
What the utility model comprised suitable overstriking is the twist shape steel bar, and described steel bar is provided with several flexible arcs, and described steel bar two ends are provided with 90 degree elbows.
As preferably, the flexible arc quantity on the described steel bar is two, lays respectively near the steel bar two ends.
Because last twist shape steel bar is provided with flexible arc, flexible arc can be used for offseting the stroke that causes because of expanding with heat and contract with cold.
The utility model also comprises the reinforced hole that is welded on the cathode frame, the elbow of an angle of 90 degrees of steel bar directly inserts in the reinforced hole that is welded on the cathode frame and crooked getting final product during installation, not only installation and maintenance are very convenient, and are connected firmly, thereby can guarantee equipment safety operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of the utility model when cooperating with cathode frame;
Fig. 4 is the structural representation of reinforced hole among Fig. 3.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises the steel bar 1 that is twist shape, and steel bar 1 is provided with two flexible arcs 2, lays respectively near steel bar 1 two ends, and the direction of the arc of cathode line is parallel with the flue gas direction during installation, and steel bar 1 two ends also are provided with 90 degree elbows 3.
As Fig. 3, shown in Figure 4, when twist shape steel bar 1 is installed on cathode frame 10, make twist shape steel bar 1 perpendicular to cathode frame 10 bases, bottom is provided with some groups of reinforced holes 4 on the cathode frame 10, every group of reinforced hole 4 is arranged side by side, its hole direction is consistent with the cathode frame length direction, reinforced hole 4 adopts the U-shaped reinforcing bar to be welded on the cathode frame center line, because steel bar of the present utility model 1 two ends are provided with the elbow 3 that bends to 90 degree, elbow 3 can insert in the reinforced hole 4, and make its end crooked fixing, can guarantee the in use unlikely fracture of the utility model like this, and, can be used for offseting the stroke that causes because of expanding with heat and contract with cold, thereby support equipment safe and reliable operation because the utility model is provided with flexible arc 2.When installation, not impaired in order to ensure cathode line because of workmen's body weight, also can be equipped with working tensioning pull bar 11, the centre of tensioning pull bar 11 is provided with regulates bolt 12, regulate bolt 12 effect be the tensioning degree of regulating cathode frame 10, tensioning pull bar 11 is determined installation site and quantity as required, and moves or remove with installation progress, can guarantee construction safety like this and avoid cathode line to sustain damage in installation process.
Claims (3)
1. an electric cleaner comprises the steel bar that is twist shape with anti-flexible twist shape cathode line, and it is characterized in that: described steel bar is provided with several flexible arcs, and described steel bar two ends are provided with 90 degree elbows.
2. electric cleaner according to claim 1 is with resisting flexible twist shape cathode line, and it is characterized in that: the flexible arc quantity on the described steel bar is two, lays respectively near the steel bar two ends.
