Abstract
The utility model provides a tension-adjustable spiral line for an electric dust collector, which comprises a spiral line body (1), a hanger latch (2), a concave gasket (3), an eye bolt (4), a nut (5), a spring gasket (6), a pin (7) and a connecting plate (8). The spiral line is characterized in that the spiral line body (1) is formed by winding a metal wire with good elasticity. Compared with the prior art, the spiral line has the advantages that the tension of the spiral line is far less than the maximum pulling force thereof, which can substantially eliminate the possibility of broken wire. Besides, the pulling force of the spiral line can be adjusted to meet the needs for different vibratory beating conditions; and when the spiral line is applied under a top vertical vibratory beating condition, the strength of the spiral line is allowed to be further reduced to achieve the purpose of saving costs.
Description
Technical field
The utility model relates to field of environmental engineering, relates in particular to a kind of electric cleaner adjustable helix of tensile force.
Background technology
The spirality cathode line of using on the electric cleaner (abbreviation helix) has characteristics such as the electric field discharge is even, energy-saving effect is remarkable, efficiency of dust collection is high, easy for installation at present.The entity of common spirality cathode line be a kind of close around extension spring, in the time of in the middle of it is installed to electric cleaner, it need be drawn into very long state, its pitch can surpass more than 2 times of coil diameter, maximum pull when at this moment the tensile force of helix also reaches this length, so-called tensile force are exactly the pulling force that helix produces framework under the installment state.Helix work the time also needs constantly to be subjected to the impact of beater, bigger rocking and constantly vibration takes place, so circular helix is very high to the requirement of material, is with the very high stainless steel wire coiling of nickeliferous and chromium.The performance of metallic nickel creep resistant and plastic deformation is good, but their price is very expensive, even if still there is the situation of broken string to occur like this, makes that ours is very not steady and sure at heart.The quantity of cathode line is very big in the electric cleaner, and a Generator Set electric cleaner helix heater line reaches tens thousand of, and its production cost height is bigger to the influence of totle drilling cost.
Discover that further the mounting means of helix is just directly to hook hook hole after elongating installation length at present, its tensile force is exactly a maximum pull, and is difficult to its tensile force is made adjustment.Fact proved that the direction of the mode rapping power of the vertical rapping in top is parallel with the length direction of cathode line, is not easy to cause rocking of cathode line, the tensile force of its target line requires quite low.If its tensile force can decrease than maximum pull under the situation of side rapping, allow it away from the duty of ultimate tension, its reliability also can be improved significantly.
The performance of cathode line is extremely important to electric cleaner, in environmental requirement more and more higher today, because the flash-over characteristic of cathode line and the high-quality degree that dust-collecting efficiency, reliability are directly connected to electric cleaner.The deficiency and the defective of the helix that uses make its popularization be subjected to certain limitation at present.Environmental protection industry (epi) presses for lower, the high cathode line that can adapt to different rapping modes again of reliability of several existing good discharge effect, production costs at present.
Summary of the invention
The utility model provides that a kind of external diameter is less, production cost is lower, the adjustable helix of tensile force.
A kind of electric cleaner is with the adjustable helix of tensile force, comprises helix main body, hook snap close, eye bolt, nut, spill pad, spring shim, pin and is installed in gusset piece on the framework.
The helix main body adopts elasticity good metal filament winding system to form, and preferably adopts the spring steel wire manufacturing, turns to the spring of the certain external diameter and the number of turns according to the length that needs are installed, and simultaneously two ends is bent to hook-shaped, and establishes the hook snap close at the opening part of linking up with.Surpassed elastic limit already when helix is stretched to needed length, can only have shunk a part after loosening, pitch is still bigger, if this length as original state, length of La Shening and its pulling force are proportional substantially again.According to this rule, we move helix to after the Len req certain value is installed in advance and loosen into free state again, and tensile force just diminishes when it is stretched to installation length again, makes helix be operated in low load condition, and concrete size is decided by the test back.For many years fact proved in the electric cleaner that owing to reasons such as oxygen are few, actual etching extent is very light, the life-span of common iron cathode line is also quite long, the ordinary elasticity material also should be able to be made long-life helix.
Construction bolt adopts eye bolt, and the position that can buckle into pin after the position in hole and spring shim are tightened is suitable.The spill pad adopts rectangular washer, and the width and the gauge of wire of the width of spill and the degree of depth and hook are suitable, and its effect is to block hook not make and get loose.The effect that construction bolt adds spring shim is that helix is closely linked to each other with gusset piece, and it is the electric attached method of using always, and tightness degree is quite reliable.
Compared with prior art, electric cleaner that the utility model provides is with the adjustable helix of tensile force, because the tensile force of its duty obviously reduces than its maximum pull, makes it be operated in low load condition, basically the generation that can stop to break.And its pulling force adjustable size joint, adapting to the needs of different rapping operating modes, when it was applied in the vertical rapping operating mode in top, the intensity of helix and tensile force fill to be permitted further to reduce, and further reaches cost-effective purpose.The fastening means that the utility model adopts bolt, nut, spring shim to connect is the most frequently used electric connecting mode, and is solid and reliable, particularly the helix tensile force hour, its superiority is more obvious.
The electric cleaner that the utility model the provides adjustable helix of tensile force, because external diameter is less, its good rigidity, the rolling momentum is little during rapping, can avoid being in operation because die opening variation unfavorable situation greatly appears in rocking of helix, more favourable to improving efficiency of dust collection.
Description of drawings
Fig. 1 is the structural representation of the utility model electric cleaner with the adjustable helix of tensile force.
The specific embodiment
As shown in Figure 1, a kind of electric cleaner adjustable helix of tensile force, comprise helix main body (1), hook snap close (2), spill pad (3), eye bolt (4), nut (5), spring shim (6), pin (7) and gusset piece (8), gusset piece (8) is welded on the framework (9).
Helix main body (1) adopts elasticity good metal filament winding system to form, and simultaneously two ends is bent to hook-shaped, and establishes hook snap close (2) at the opening part of hook.According to the physical length of framework with to the needs of tensile force size, we handle helix earlier through prestretched, loosen into free state again after being stretched to certain-length.
During on-the-spot the installation, elder generation passes the hole of the gusset piece (8) that is welded on upper frame to eye bolt (4) and puts the hook of helix (1) one end, presses spill pad (3) and spring shim (6) successively, fastening nut (5), in the hole of bolt, buckle into pin (7) and crooked again, prevent to get loose.When the other end of helix (1) is stretched to the hole of the gusset piece (8) that is welded in underframe, the process of repeat to wear bolt, pressing two kinds of pads, nuttings and wearing pin, installation.
