Abstract
The utility model relates to a kind of charging dust collecting structure of bulk cement, comprise the feed bin that side is provided with sweep-up pipe, the lower end of feed bin is provided with discharge nozzle, discharge nozzle is placed in flexible soft bag, the lower end of feed bin is fixed with dust retaining ring by coupling link, and dust retaining ring is housing structure, and its housing cavity upper end is closed by coupling link, be connected with sweep-up pipe by arm outside it, its lower end is with air suction opening.In the utility model, by installing dust retaining ring in the lower end of discharge nozzle, the dust emission of the soft sack that effectively prevents from stretching during blowing, and improve dust collection efficiency when gathering dust, has that structure is simple, service-strong feature.
Description
Technical field
The utility model relates to field of cement production equipment, particularly the charging dust arrester installation of bulk cement.
Background technology
In existing bulk cement feeding device, generally on feed bin, connect cleaning shaft, after feed bin blowing completes, cleaning shaft carry out dedusting place to feed bin and the junction of flexible soft bag, discharge nozzle due to feed bin lower end is placed in flexible soft bag, the dust of flexible soft bag inside can only be absorbed during dust removing tube dust suction, the outside dust of flexible soft bag and discharge nozzle cannot be absorbed; Further, existing feeding device, dust is easily overflowed in the inlet point place of the soft bag of dedusting, causes sack dust emission more.
Utility model content
The above-mentioned shortcoming that the applicant exists for prior art, carries out studying and improving, provides a kind of charging dust collecting structure of bulk cement, and it has, and airborne dust is few, dust suction feature thoroughly.
In order to solve the problem, the utility model adopts following scheme:
A kind of charging dust collecting structure of bulk cement, comprise the feed bin that side is provided with sweep-up pipe, the lower end of feed bin is provided with discharge nozzle, discharge nozzle is placed in flexible soft bag, the lower end of feed bin is fixed with dust retaining ring by coupling link, and dust retaining ring is housing structure, and its housing cavity upper end is closed by coupling link, be connected with sweep-up pipe by arm outside it, its lower end is with air suction opening.
Further improvement as technique scheme:
Described dust retaining ring is low wide and up narrow skirt structure, its lower end with tilt anchor ring, with air suction opening on anchor ring.
Multiple air suction opening is uniformly distributed around dust-break Ring current distribution on anchor ring.
Multiple air suction opening is uniformly distributed around dust-break Ring current distribution.
The sidewall of described discharge nozzle is with multiple through hole.
The center shaft of described through hole is tilted to lower setting relative to the tubular axis of discharge nozzle.
Technique effect of the present utility model is:
In the utility model, by installing dust retaining ring in the lower end of discharge nozzle, the dust emission of the soft sack that effectively prevents from stretching during blowing, and improve dust collection efficiency when gathering dust, has that structure is simple, service-strong feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, feed bin; 2, sweep-up pipe; 3, discharge nozzle; 31, through hole; 4, flexible soft bag; 5, dust retaining ring; 51, anchor ring; 52, air suction opening; 6, arm; 7, coupling link.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the charging dust collecting structure of the bulk cement of the present embodiment, comprise the feed bin 1 that side is provided with sweep-up pipe 2, the lower end of feed bin 1 is provided with discharge nozzle 3, and discharge nozzle 3 is placed in flexible soft bag 4, and the lower end of feed bin 1 is fixed with dust retaining ring 5 by coupling link 7, dust retaining ring 5 is housing structure, its housing cavity upper end is closed by coupling link 7, and be connected with sweep-up pipe 2 by arm 6 outside it, its lower end is with air suction opening 52.The utility model adopts dust retaining ring 5, by being closed in dust retaining ring 5 outside the charging oral area of flexible soft bag 4, during discharge nozzle 3 discharging, raises outside dust retaining ring 5 blocks dust, thus reduces dust emission; When gathering dust, the outside absorption of the just flexible soft bag 4 of air suction opening 52 of dust retaining ring 5 lower end, flexible soft bag 4 forms a space closed with the below of feed bin 1, thus improves dust collection efficiency.
As shown in Figure 1, dust retaining ring 5 is low wide and up narrow skirt structure, and its lower end is with the anchor ring 51 tilted, and with air suction opening 52 on anchor ring 51, multiple air suction opening 52 is uniformly distributed around the center of dust retaining ring 5 on anchor ring 51.The anchor ring 51 tilted is for increasing the area of contact of dust retaining ring 5 and flexible soft bag 4, thus sealing effect when improving blowing and adsorption affinity when gathering dust between dust retaining ring 5 and flexible soft bag 4.
As shown in Figure 1, the sidewall of discharge nozzle 3 is with multiple through hole 31, and the center shaft of through hole 31 is tilted to lower setting relative to the tubular axis of discharge nozzle 3.The setting of through hole 31, improves dust collection efficiency when gathering dust largely.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changing or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
