Abstract

The utility model discloses a fixing structure of a star-shaped corona wire. The fixing structure consists of a protective sleeve and two wedges, wherein the star-shaped corona wire is embedded into a small cathode frame; the protective sleeve is fixedly connected to the star-shaped corona wire and is positioned at a joint between the star-shaped corona wire and the small cathode frame; the two wedges are wedged into a space between the protective sleeve and the small cathode frame in forward and reverse directions. According to the fixing structure, the star-shaped corona wire is convenient to install and adjust, a discharge effect cannot be generated, the service life is further prolonged, and a cathode device can stably operate for a long time.

Description

A kind of fixed structure of star corona wire

Technical field

The utility model relates to a kind of annex of cathode device of electric precipitator, refers in particular to a kind of fixed structure of star corona wire.

Background technology

In electric cleaner technology, adopt star corona wire to there is good discharge performance, and star corona wire price is lower, and in cathode assembly, the fixed effect quality of star corona wire and negative electrode small frame directly have influence on service life of star corona wire.

Cathode assembly of the prior art generally adopts star corona wire 10 directly and the state of negative electrode small frame 20 spot welding determines mode, as shown in Figure 1, or adopt nut 30 locking star corona wires 10, then by the consolidation style of

nut

30 and 20 spot welding of negative electrode small frame, as shown in Figure 2.The shortcoming of described two kinds of consolidation styles is: install inconvenient, and the fixed position of star corona wire and negative electrode small frame leaves crator, crator easily produces discharge effect, electric discharge crator is easily etched electrochemically fixed position, thereby the situations such as causing star corona wire to produce goes offline, broken string, finally cause the frequent short circuit of electric field, affect the bringing normally into operation of electric cleaner, and increase repair and maintenance workload, affect the efficiency of dust collection of electric cleaner.

In view of defect described in the fixed structure of prior art star corona wire, inventor's further investigation, develops a kind of fixed structure that overcomes the star corona wire of described defect, and this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of installation easy to adjust, and the fixed structure of the star corona wire increasing the service life.

For reaching above-mentioned purpose, solution of the present utility model is:

A fixed structure for star corona wire, is comprised of protective sleeve and chock; Star corona wire embeds in negative electrode small frame, and protective sleeve is cemented on star corona wire, is positioned at the junction of star corona wire and negative electrode small frame; Two chocks are between both forward and reverse directions wedging protective sleeve and negative electrode small frame.

Further, protective sleeve shape is mated with star corona wire, and by steel pipe or the moulding of band steel processing and fabricating.

Further, two wedging faces of chock are respectively equipped with anti-skidding toothed segment.

Further, chock manufactures type by round steel material.

Adopt after such scheme; the utility model protective sleeve is cemented on star corona wire; two chocks are between both forward and reverse directions wedging protective sleeve and negative electrode small frame, make the wedging of star corona wire on negative electrode small frame, strengthen the fixing of star corona wire and negative electrode small frame.Therefore, it is easy to adjust that the utility model is installed star corona wire, and can not produce discharge effect, and then increase the service life, and guarantees the long-term stability operation of cathode assembly.

Meanwhile, the wedging face of chock is provided with double-sided anti-slip toothed segment, effectively prevents that chock from coming off, and then makes star corona wire wedge jail on negative electrode small frame, further strengthens the fixing of star corona wire and negative electrode small frame.

The specific embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

Consult shown in Fig. 3 to Fig. 5, the fixed structure of a kind of star corona wire that the utility model discloses, is comprised of protective sleeve 1 and chock 2.

Star corona wire 3 embeds in negative electrode small frame 4, and protective sleeve 1 is cemented on star corona wire 3, is positioned at the junction of star corona wire 3 and negative electrode small frame 4.As shown in Figure 8, protective sleeve 1 shape is mated with star corona wire 3, and the shape of protective sleeve 1 is also star, and through Mould Machining, makes moulding by steel pipe or band steel.

Two chocks 2 are between both forward and reverse directions wedging protective sleeve 1 and negative electrode small frame 4, and upward, and another chock 2 tips down in chock 2 tips.As shown in FIG. 6 and 7, two wedging faces of chock 2 are respectively equipped with anti-skidding toothed segment 21.Chock 2 is made moulding by round steel material through Mould Machining.

The utility model utilizes protective sleeve 1 protection star corona wire 3, and by the chock 2 of two both forward and reverse directions, wedge, between protective sleeve 1 and negative electrode small frame 3, makes 3 wedgings of star corona wire on negative electrode small frame 4.Meanwhile, two wedging faces of chock 2 are respectively equipped with anti-skidding toothed segment 21, effectively prevent that chock 2 from coming off, and then make star corona wire 3 further wedge jails on negative electrode small frame 4.Chock 2 use round steel materials are integrally formed through Mould Machining, and protective sleeve 1 adopts steel pipe or band steel to make moulding through Mould Machining, and both all can realize production in enormous quantities, reduce production costs.Meanwhile, chock 2 and protective sleeve 1 have do not shrink, indeformable, feature easy to adjust is installed, solved star corona wire two ends easily by galvano-cautery, go offline, the problem such as broken string, further guaranteed the discharge effect of cathode assembly.

The foregoing is only preferred embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
