Utility model content
The utility model mainly solves the easily glutinous stifled technical problem that windage strengthens, service life is short, cost is higher that causes of cloth bag of the boiling drier of prior art; A kind of auxiliary device for reducing dust of boiling drier that can improve efficiency of dust collection, reduction use cost is provided.
In order to solve the technical problem of above-mentioned existence, the utility model is mainly to adopt following technical proposals:
A kind of boiling drier of the present utility model is assisted device for reducing dust, described boiling drier comprises casing, the hot air apparatus being connected with casing and air exhausting device, described casing comprises the air inducing dedusting section of arranging from top to bottom, ebullated bed body and wind inlet section, one side of described ebullated bed body is provided with charging aperture, the opposite side of the relatively described charging aperture of ebullated bed body is provided with discharging opening, between the bottom of ebullated bed body and wind inlet section, be provided with air distribution plate, described auxiliary device for reducing dust comprises enlarged body, described enlarged body is located between air inducing dedusting section and ebullated bed body, the cross section of enlarged body is inverted trapezoidal, enlarged body lower ending opening matches with the open top of ebullated bed body and is connected with the open top of ebullated bed body, enlarged body upper end open matches with air inducing dedusting section lower ending opening and is connected with air inducing dedusting section lower ending opening, be the enlarged body of the reducing of inverted trapezoidal shape, make to be entrained with the waste gas of dust granules because of the expansion reduction of speed of area, a part is heavier and again fall in ebullated bed body because of Action of Gravity Field compared with large dust granules or material, yield rate and the rate of recovery of material are improved, also alleviated the load of air inducing dedusting section, reduce use cost.
As preferably; the top of described enlarged body is provided with the screen cloth that matches with enlarged body top and be connected with enlarged body top; screen cloth can be used as the preposition filtration of filter bag dedusting; large a part heavier dust granules or material collision can be stopped to get off and again fall in ebullated bed body; reduce the dedusting load of filter bag, extended the service life of filter bag and purged interval.
As preferably, described screen cloth comprises left sieve and the right sieve of the downward-sloping and interconnective mirror symmetry of head, the afterbody of described left sieve and right sieve is connected with corresponding top margin and the sidewall of described enlarged body respectively with side, the cross section that left sieve and right sieve form is back taper, vertex of a cone taper screen designs down, can reduce the dust accumulation phenomenon that horizontal screen cloth exists, the dust granules that the sieve of inclination makes to become scattered about in sieve can glide and drops down onto the vertex of a cone and be again back in ebullated bed body in the effect of gravity.
The beneficial effects of the utility model are: the enlarged body of setting up the reducing that is inverted trapezoidal shape between the air inducing dedusting section of casing and ebullated bed body; make to be entrained with the waste gas of dust granules because of the expansion reduction of speed of area; a part is heavier and again fall in ebullated bed body because of Action of Gravity Field compared with large dust granules or material; yield rate and the rate of recovery of material are improved; also the load that has alleviated air inducing dedusting section, has reduced use cost.
