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, and provides a kind of charging structure that gathers dust of dust-break formula 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 structure that gathers dust of dust-break formula 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 outer wall of discharge nozzle is fixed with the dust retaining ring being placed in its outer circumferential side by connecting leg, dust retaining ring is housing structure, the two ends of connecting leg are communicated with the inner chamber of discharge nozzle and dust retaining ring respectively, the upper surface of dust retaining ring is provided with the arm be communicated with between its inner chamber and sweep-up pipe, the lower surface of dust retaining ring with arranging air suction opening more, and many row's air suction openings are uniformly distributed around dust-break Ring current distribution.
Further improvement as technique scheme:
The lower surface of described dust retaining ring with the anchor ring tilted, with arranging air suction opening on anchor ring more.
Many rows air suction opening is uniformly distributed around dust-break Ring current distribution on anchor ring.
The center shaft of described through hole is tilted to lower setting relative to the tubular axis of discharge nozzle.
The Central Symmetry of the many relative discharge nozzles of connecting leg is arranged.
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, dust retaining ring and sidewall are with the setting of the discharge nozzle of through hole, improve dust collection efficiency when gathering dust, the utility model has that structure is simple, the feature of reliable operation.

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 structure that gathers dust of the dust-break formula 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, discharge nozzle 3 is placed in flexible soft bag 4, the outer wall of discharge nozzle 3 is fixed with the dust retaining ring 5 being placed in its outer circumferential side by connecting leg 7, dust retaining ring 5 is housing structure, the two ends of connecting leg 7 are communicated with the inner chamber 50 of discharge nozzle 3 and dust retaining ring 5 respectively, the upper surface of dust retaining ring 5 is provided with the arm 6 be communicated with between its inner chamber 50 and sweep-up pipe 2, the lower surface of dust retaining ring 5 is with many row's air suction openings 52, many rows air suction opening 52 is uniformly distributed around the center of dust retaining ring 5 on anchor ring 51.
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 2 and Figure 3, dust retaining ring 5 is column construction, and its lower end is with the anchor ring 51 tilted, and with many row's air suction openings 52 on anchor ring 51, many row's air suction openings 52 are 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.
