Description
Technical field
The present invention relates to the canned production process equipment of a kind of carbon dust, relate in particular to the canned sealing configuration of a kind of carbon dust.
Background technique
Activated carbon powder has adsorption property, and canister generally is contained in before petrol tank and the motor.Because gasoline is a kind of volatile liquid, fuel tank often is full of steam at normal temperatures, and the effect of automotive fuel evaporative emission control system is with steam introducing burning and prevents to evaporate in the atmosphere that what this process played an important role is charcoal canister storage system.Canister is generally plastic material, is tubular structure, and its preparation process flow process roughly is divided into the lower cover welding, and carbon dust is canned, the upper shell cover welding.Wherein carbon dust is canned is a wherein crucial link, at present, and at the carbon dust pot-type equipment, like Fig. 1,2 said showing; Comprise equipment head 1, canned 2, sealed bolster plate 3, discharge tank 4; Welding melt 5, carbon power pot 6, when canned, discharge tank 4 inserts carbon power pot 6 under canned 2 effect; Sealed bolster plate 3 covers on welding melt 5, and carbon power pot 6 is sealed, and this moment, discharge tank 4 was irritated into carbon power pot 6 with carbon dust, again carbon power pot is moved on to the welding machine place and carries out the upper shell cover welding.The problem that exists at present is that when carbon dust was canned, a lot of carbon dusts of meeting absorption welded melt 5 and directly contact with sealed bolster plate 3 again on the sealed bolster plate 3; Cause welding on the melt 5 and also can adsorb carbon dust, thereby cause weld strength to reduce, to such an extent as to the welding blow-by; Cause leaking carbon dust, after the carbon filling is installed on the fuel tank of vehicle, because carbon dust is revealed; Cause gasoline vapor to evaporate in the atmosphere, improved the discharging of automobile, polluted the efficiency that environment has also reduced automobile simultaneously.To this problem, the canister manufacturer that has adopts the carbon dust on the vacuum cleaner absorption welding melt 5, but the absorption process that increases; Cause cost increases such as cost of labor; Control by manual operation simultaneously, be difficult to also guarantee that carbon dust is fully absorbed, be difficult to the quality of production of guaranteeing that carbon is irritated.
Summary of the invention
The technical problem of the actual solution of the present invention is: when carbon dust is canned, can adsorb a lot of carbon dusts on the sealed bolster plate 3, welding melt 5 directly contacts with sealed bolster plate 3 again; Cause welding on the melt 5 and also can adsorb carbon dust; Thereby cause weld strength to reduce, even the welding blow-by, cause leaking carbon dust.
The invention provides the canned sealing configuration of a kind of carbon dust, comprise the head 1 of carbon dust pot-type equipment, canned 2, discharge tank 4; Sealing material, carbon power pot 6, said discharge tank 4, carbon power pot 6 are hollow cylinder; Said head 1 below is fixedly connected with canned 2, and said canned 2 below is fixedly connected with discharge barrel 4, and said discharge tank 3 is positioned at directly over the carbon power pot 6 and is coaxial with carbon power pot 6; External diameter is characterized in that less than the internal diameter of said carbon power pot 6: said sealing material is a stuffing box gland, and said stuffing box gland is nested and be fixed on the outer circumference face of said discharge tank 4; When canned, be positioned at the below of said welding melt 5, do not contact with said welding melt 5; The external diameter of said stuffing box gland is slightly larger than the internal diameter of said carbon power pot 6, makes said stuffing box gland and said carbon power pot 6 interference fit, makes said discharge tank 4 and carbon power pot 6 sealings.
Said stuffing box gland is the tetrafluoroethylene stuffing box gland.
The thickness of said stuffing box gland is 15～45mm.
As shown in Figure 5, said discharge tank 4 can also be the semicircular ring cylindrical shell, and said carbon power pot 6 is corresponding semicircular ring cylindrical shell.
Beneficial effect of the present invention is: simple in structure, carbon dust is no longer leaked in welding, and weld strength improves greatly, and the welding pulling capacity strengthens 20%; The welded seal degree improves greatly, makes canister produce whole reject ratio and reduces by 1.5%, has improved carbon dust can product qualified rate greatly; Save the operation of using vacuum cleaner to absorb carbon dust on the welding melt, improved the production automation, improved quality of product; Reduce labor cost, used and reequiped convenience, be fit to the popularization on a large scale of carbon dust can production field.
