Description
[technical field]
The utility model relates to a kind of electric cleaner corona discharge electrode seal, and relating in particular to a kind of is the lateral attitude adjustable electric cleaner full-plastic corona discharge electrode seal of insulating materials to strengthen MC nylon.
[background technology]
MC nylon is a kind of nylon made from specific process 6, belongs to the new varieties of a sudden emergence of nylon family.
Nylon has another name called polyamide, is to contain amide structure on the high polymer main chain
High polymer, generally can be by the amino acid polycondensation, corresponding diacid and two fat polycondensations or form by the lactams ring-opening polymerisation.Pass through hydrolytie polycondensation by caprolactam, alkaline anionic polymerization, the product that methods such as solid phase polycondensation and intercalation polymeric obtain is called nylon 6, and wherein anionic polymerization is the main method that obtains high-quality nylon 6.The initator of anionic polymerization has sodium alkoxide, NaOH, Na
2CO
3With metal Na etc., the monomer water content requires less than 300 * 10
-6, the pre-polymerization merging vacuumizes dehydration under 120-140 ℃ of temperature.After prepolymerization is finished, performed polymer is injected the good mould of preheating, continue reaction 0.5-1h 140-160 ℃ of temperature, both can obtain polymer.This nylon 6/poly compound is called monomer cast nylon again, i.e. MC nylon.
MC nylon has light weight, relative density is little, specific strength is high, wear-resisting and self-lubricating property outstanding, mechanical performance, chemical stability is good and good processing properties arranged, product dimensional stability and desirable shock-absorbing preferably, voiceless sound and foreign matter buried advantage such as performance.What deserves to be mentioned is that with general-purpose plastics or other macromolecular material ratio, MC nylon also has higher hear resistance and electrical insulation capability.Represent according to the UL relative temperature index that the U.S. insurance industry research department determines, comprise that the special engineering plastics of MC nylon generally all surpasses 150 ℃, and after glass fibre strengthened, the serviceability temperature index also contained 10-30 ℃ of raising.The electric insulation index of MC nylon is 18KV/mm, and is identical substantially with quartzy insulating properties, but performance index is stable.Because above advantage is arranged, MC nylon has been widely used in metallurgy, smelting, chemical industry and environmental protection equipment at present.In the environmental protection cleaner, it is to substitute quartzy optimal selection as the electric cleaner insulating materials.
The present large-scale electric cleaner that uses, operating voltage generally is DC60-DC80KV.Frame ground and with positive plate group equipotential, corona discharge electrode is introduced from case top cover plate perforation, the insulation between corona discharge electrode and the cover plate is that the corona discharge electrode seal that adopts quartzy basin and quartz ampoule to form is finished.
The quartz material that uses on the current industrial is quartz sand melting in three-phawse arc furnace and forms, owing to be subjected to the restriction of process conditions, very easily forming in the quartzy tubing with carbon black pellet is the slag inclusion of main form.Owing to the existence of these slag inclusions, the insulating properties of quartz ampoule material have been influenced greatly; Add the influence that is subjected to the quartzy tubing blank case hardness behind the melt casting, the quartz ampoule and the quartzy basin inside and outside circle cone face process precision utmost point be cannot say for sure card, and this has limited the installation accuracy of corona discharge electrode framework in the electric cleaner housing again.Equipment and efforts at environmental protection personnel find that by long-term practice electric cleaner corona discharge electrode seal is that restriction electric cleaner operating voltage raises, and then has a strong impact on one of key factor of its dust-collecting efficiency.Owing to above reason,, in the electric field very easily " creepage ", can cause equipment downtime when serious on a higher voltage level if electric cleaner is worked.Because general factory electric cleaner all is the unit operation; and can not overhaul by off-line; under the condition that does not possess system-down; enterprise often can only tolerate that electric cleaner works under a lower voltage; under this voltage conditions; efficiency of dust collection is impossible improve, and this is to be the acts and efforts for expediency of cost with the sacrificialing environment protection.
Traditional electric cleaner is between quartzy basin and base, quartzy basin and quartz ampoule; be filled with asbestos cord and add waterglass; not quick detachable after being arranged on it and solidifying like this; in case quartz ampoule is breakdown; the on-the-spot work difficulty of changing is quite arduous, owing to work under hard conditions, operating efficiency is very low; and from the angle of labour protection and production safety, this working method is unallowed often.For many years, people are exploring a kind of installation accuracy height always, non-damageable electric cleaner corona discharge electrode seal.
[utility model content]
In order to overcome in the prior art because of quartzy tubing slag inclusion and the not high reason of installation accuracy, and the rising of restriction electric cleaner operating voltage, and after quartz ampoule punctures because of " creepage ", not easily changeable shortcoming, the utility model provides a kind of the utilization to strengthen insulation basin and the insulation tube of MC nylon for insulating materials, and base is provided with laterally adjustable corona discharge electrode insulation scheme on the cover plate of electric cleaner case top, thereby realize a kind of installation accuracy height, the electric cleaner full-plastic corona discharge electrode seal of not fragile and easy replacing.
The technical scheme that its technical problem that solves the utility model adopts is: electric cleaner full-plastic corona discharge electrode seal, comprise base, insulation basin and insulation tube, this base is formed by the steel plate rivet welding, be provided with cone in the described base, this cone socket-connects with the insulation basin, and the conical section of insulation basin and insulation tube socket-connects.
Described base matrix and cone welding, the base plate on this base is a rectangle, and the screw on this base plate is equidirectional slotted hole.
Described base cone internal conical surface tapering is identical with insulation basin outer conical surface tapering.
Described insulation basin internal conical surface tapering is identical with insulation tube conical section outer conical surface tapering.
The beneficial effects of the utility model are: utilizing enhancing MC nylon is that material is made insulation basin and insulation tube, all screws are equidirectional slotted hole on the base plate of base, so that base can laterally be adjusted along electric cleaner when mounted, make the interior corona discharge electrode framework of housing reach higher installation accuracy, thereby realize a kind of installation accuracy height, the corona discharge electrode seal of not fragile and easy replacing.
