Description
Technical Field
The utility model relates to a field of gathering dust especially relates to a rotary kiln head kiln tail dust arrester installation.
Background
The rotary kiln is an important production device for cement production and processing, and a dust collection device of the rotary kiln generally adopts a box type pulse bag type dust collector. Along with the development of national economy, the national environmental protection standard is also continuously improved, the cement yield is higher and higher, dust collectors used by rotary kilns of a plurality of cement manufacturers are used for a long time and are gradually old, the dust removal efficiency is poor, the ventilation effect of the dust collectors is poor, the wind resistance is high, the pressure difference between the inlet and the outlet of the dust collectors is high, the reduction of the power consumption and the exertion of the capacity of a dust collection system at the head and the tail of the rotary kiln are influenced, the dust concentration index in an exhaust chimney basically exceeds 20mg/m for carrying, and the requirements exceed the requirements of local emission standards and cannot meet the current production requirements.
If all the dust collectors are replaced, the operation burden of enterprises is large. Therefore, it is necessary to modify it. The bag cage bears the dust removal cloth bag, and the structure of the bag cage greatly influences the dust removal area and the wind resistance of the dust removal cloth bag.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a rotary kiln head kiln tail dust arrester installation.
In order to realize the purpose, the technical scheme of the utility model is that: a rotary kiln head and kiln tail dust collecting device comprises a box-type bag dust collector, wherein a plurality of bag cages and dust collecting bags are arranged in the box-type bag dust collector, each bag cage comprises a circular base and a bag cap, a plurality of vertical ribs are annularly and uniformly distributed between the base and the bag cap, two ends of each vertical rib are respectively welded and fixed with the base and the bag cap, a plurality of fixing rings with equal intervals are arranged in the length direction of each vertical rib, the outer rings of the fixing rings are fixedly connected with the vertical ribs in a welding manner, and the fixing ring parts between the adjacent vertical ribs are inwards sunken to form an arc shape; and a flow guide pipe is welded and fixed on the bag cap, and the inner diameter of the flow guide pipe is the same as that of the fixing ring.
Preferably, adjacent two the solid fixed ring between all be equipped with the quick-connect structure on the perpendicular muscle, the quick-connect structure includes the loose joint nut, two solid fixed ring between the perpendicular muscle cut apart into two parts, one end is equipped with the screw thread on its both ends that dock, sets up the loose joint nut on the other end.
The utility model has the advantages that: 1. the fixed ring is arc-shaped towards the inner groove, so that the effective filtering area is effectively increased compared with the traditional annular structure; 2. the guide pipe is arranged at the opening of the bag cap, so that the use area of the filter bag can be increased, and the resistance of the dust collector can be reduced; 3. the vertical ribs are provided with quick structures, so that the vertical ribs are convenient to disassemble, transport and install, and can be increased when old equipment is transformed, and the increasing capacity requirement can be adapted.

Fig. 2 is a schematic structural view of the fixing ring in fig. 1.
Fig. 3 is a schematic structural diagram of embodiment 2 of the present invention.
Detailed Description
The present invention will be further described with reference to the following specific embodiments.
Example 1
As shown in fig. 1 and 2, a rotary kiln head and kiln tail dust collecting device comprises a box-type bag dust collector, wherein a plurality of bag cages and dust collecting bags are arranged in the box-type bag dust collector, each bag cage comprises a circular base 1 and a bag cap 2, a plurality of vertical ribs 3 are annularly and uniformly distributed between the base and the bag cap, two ends of each vertical rib are respectively welded and fixed with the base and the bag cap, a plurality of fixing rings 4 with equal intervals are arranged in the length direction of each vertical rib, the outer rings of the fixing rings are fixedly connected with the vertical ribs in a welding manner, and the fixing ring parts between the adjacent vertical ribs are inwards sunken into an arc shape, so that the effective filtering area is effectively increased compared with that of a traditional annular structure; the guide pipe 5 is welded and fixed on the bag cap, the inner diameter of the guide pipe is the same as that of the fixing ring, and the structure can improve the use area of the filter bag and reduce the resistance of the dust collector.
Example 2
As shown in fig. 3, on the basis of embodiment 1, the vertical ribs between two adjacent fixing rings are provided with quick-connect structures 6, each quick-connect structure includes a loose-joint nut 7, the vertical rib between two fixing rings is divided into two parts, one end of the butted two ends of each quick-connect structure is provided with a thread 8, and the other end is provided with the loose-joint nut 7 (the loose-joint nut is in the prior art and is in a nut shape, but a baffle plate with a through hole is arranged on one end surface, and the diameter of the through hole is smaller than the inner diameter of the nut). The structure of the embodiment is convenient to disassemble, transport, install and grow when old equipment is transformed so as to adapt to the increasing capacity requirement.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, all according to the utility model discloses a technical scheme makes technical deformation, all falls into within the protection scope of the utility model.
