Abstract
The utility model relates to an insertion type airflow distributor of an electrical dust cleaner, which mainly comprises a sealed cover, a lower flange, an upper flange, stud bolts, a nut, a spring and an airflow distribution plate, wherein a diversion hole is arranged on the airflow distribution plate, the lower flange is welded with a shell of the electrical dust cleaner, the upper flange is welded with the airflow distribution plate; the upper flange, the lower flange and the spring are connected as a whole through the stud bolts, and the sealed cover is connected with the lower flange through the stud bolts. The length of the diversion hole of the airflow distribution plate of the utility model is much smaller than that of the ordinary electrical dust cleaner, a cylindrical surface which is arranged in the diversion hole is provided with a corrosion-resistant alloy plating layer, therefore the diversion hole has a function that the diversion hole is not easy to block. Meanwhile, the insertion type airflow distributor of an electrical dust cleaner with a disassembly function is convenient for disassembly. When the airflow distribution plate is blocked, a spare clean airflow distribution plate can be used for replacing the airflow distribution plate, and then, the airflow distribution plate can be cleaned. The requirements of high efficiency and long period operation of the electrical dust cleaner can be satisfied.
Description
[technical field]
The utility model relates to a kind of electric cleaner airflow-distribution board, relates in particular to a kind of embedded airflow distribution device of electric cleaner with disassembling function.
[background technology]
The present large-scale electric cleaner that uses, at import changeover portion and outlet changeover portion, all be provided with 1 to 3 layer of airflow-distribution board, utilize the uniform effect of porous plate to air-flow, improve electric cleaner internal gas flow distribution effect, thereby improve the electric cleaner dust-collecting efficiency effectively.Because the electric cleaner condition of work is more abominable, particularly under the uniform temperature condition, the dust that has has viscosity, although air-flow distribution rapping apparatus has been installed, but still the local phenomenon of blocking of pod apertures may appear, airflow-distribution board was lost efficacy, removed the dust-collecting efficiency of electric cleaner greatly low.On the other hand; 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 tolerates that electric cleaner works under a low efficiency of dust collection state, this is with the acts and efforts for expediency of sacrificialing environment protection as cost.
Traditional electric cleaner airflow-distribution board is fixed on the electric cleaner housing with welding or bolt type of attachment, the inconvenience dismounting, in case airflow-distribution board stops up, cleaning work must be carried out at the scene.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 the electric cleaner airflow distribution device of a kind of difficult obstruction, easy cleaning always.
[utility model content]
Very easily stop up in order to overcome existing electric cleaner airflow-distribution board pod apertures, and owing to install and reasons in structure easy to clean not, the shortcoming that easily causes the effect of electric cleaner airflow distribution device airflow uniform distribution to be lost efficacy, the utility model provides a kind of pod apertures inlet side chamfering, the airflow-distribution board of hole inner cylinder face brush plating, and pack into from the electric cleaner top, thereby realize that a kind of pod apertures is difficult for stopping up and the embedded airflow distribution device of electric cleaner of cleaning very easily with embedded mode.
The technical scheme that its technical problem that solves the utility model adopts is: the embedded airflow distribution device of electric cleaner, mainly comprise seal closure, lower flange, upper flange, stud and nut, spring, airflow-distribution board, this airflow-distribution board is provided with pod apertures, described lower flange is welded mutually with the electric cleaner housing, described upper flange is welded mutually with airflow-distribution board, upper flange, lower flange, spring connect as a whole by stud, described seal closure is connected with lower flange by bolt.
45 ° of the equal chamferings in described pod apertures inlet side, the chamfering degree of depth are 1/2 of airflow-distribution board steel plate thickness, 1 * 45 ° of the equal chamfering in air side.
Described pod apertures inner cylinder face has one deck corrosion resisting alloy coating by the technique of brush plating brush plating.
Described corrosion resisting alloy thickness of coating is 50um ± 10.
The beneficial effects of the utility model are: the utility model airflow-distribution board pod apertures length is far smaller than the common electrical deduster, and the pod apertures inner cylinder face has one deck corrosion resisting alloy coating, so pod apertures has not susceptible to plugging function; The utility model is the embedded airflow distribution device of electric cleaner with disassembling function, be convenient to dismounting, in case airflow-distribution board stops up, and clears up after cementing out with a standby cleaning gas tream distribution grid, can satisfy that electric cleaner is efficient, the needs of long-term operation.
