Abstract
An improved filter bag bottom belongs to the technical field of environment protection equipment, which comprises a filter bag tube body and round bottom cloth sewed at the bottom of the tube body. A layer of reinforced cloth is added and sewed on the periphery of the bottom of the tube body, the bottom edge of the reinforced cloth is wrapped on the filter bag round bottom cloth and seamed with the sewing of the bottom of the tube body, and a reinforced layer is formed at the bottom of the filter bag tube body. Therefore, connection seams are not exposed in a dust washing surface, the lower portion of the bag body is not easy to be abraded, maintain cost of users is greatly reduced, and simultaneously dust emission is low and stable.
Description
Technical field
The utility model belongs to the environmental protection equipment technical field, refers in particular at the bottom of a kind of improved filter bag bag that is used for gas solid separation.
Background technology
Make existing filter bag bottom is tube-shape bag body and the round bottom that is slightly larger than the straight warp of stack shell, adopts two diatom single needles directly to make.This kind filter bag bottom design is used in the production process and can produces following problem: 1, fine dust very easily enters piece abrasion suture and passes suture, and narrow line phenomenon and dust emission exceed standard at the bottom of causing bag; 2, because rigidity bag cage inserts in the filter bag, and the device pulse deashing causes a bag cage bottom to rock, and the bag end very easily produces friction in the above 10cm scope of bag body, serious wear, and life-span of the filter bag shortens, and it is big that user's maintenance cost becomes.
Summary of the invention
The utility model provides at the bottom of a kind of improved filter bag bag just in order to overcome above-mentioned deficiency, has solved bag stack shell cloth and round bottom cloth and has directly made and leave piece and cause not fine and close, bag end deficiency easy to wear.Main innovation is to set up a reinforcement cloth at the outer surface of filter bag bottom, utilizes this piece reinforcement cloth that the piece of making of filter bag round bottom cloth and stack shell bottom is coated simultaneously.
Specifically be to implement like this: at the bottom of the improved filter bag bag, comprise filter bag stack shell and the round bottom cloth of making in the stack shell bottom, the periphery that it is characterized in that stack shell bottom adds and is sewed with one deck reinforcement cloth, described reinforcement cloth base envelopes the piece of making of filter bag round bottom cloth and stack shell bottom, forms a strengthening course in filter bag stack shell bottom.For reaching the preferable effect of resistance to wearing, the strengthening course of this thickening is set to 8-12 centimetre usually.
Manufacture method is: with making earlier on the filter bag outer surface of 8-12 centimeters at the bottom of the filter bag tube with an end of the reinforcement cloth of material with filter bag of 10-14 centimeter length, the other end envelope filter bag round bottom cloth and stack shell bottom make piece after, be sewn into one with the filter bag tube bottom again.
In actual applications, remaining leftover pieces were made after the reinforcement cloth can adopt and make filter bag.Waste material is utilized again, save cost, form a strengthening course in filter bag stack shell bottom in addition, make that the friction failure time prolongs between the bag body bottom, thereby the whole piece life of bag filter be elongated.Make and the piece of bag stack shell and round bottom cloth is coated, make dust be difficult for entering piece, thereby can not wear and tear suture and penetrate the suture gap, cause life of bag filter to shorten and dust emission exceeds standard with the reinforcement cloth.
The utility model is by improving filter bag bottom piece and coat and the cloth reinforcement of bag body bottom, makes the interface piece can not be exposed to the dust wash surface and makes bag body bottom not easy to wear, and user's maintenance cost greatly reduces, and dust emission is low and stable simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
At the bottom of the improved filter bag bag, comprise filter bag stack shell 1 and the round bottom cloth of making in the stack shell bottom 3, the periphery of stack shell bottom adds and is sewed with one deck reinforcement cloth, described reinforcement cloth base envelopes the piece of making of filter bag round bottom cloth 3 and stack shell bottom, forms the strengthening course 2 of a 8-12 centimeter length in filter bag stack shell bottom.
Preparation method is: with making earlier on the filter bag outer surface of 8-12 centimeters at the bottom of the filter bag tube with an end of the reinforcement cloth of material with filter bag of 10-14 centimeter length, the other end envelope filter bag round bottom cloth and stack shell bottom make piece after, be sewn into one with the filter bag tube bottom again.
Annotate: remaining leftover pieces were made after the reinforcement cloth adopted and makes filter bag during making.
Adopt above-mentioned design and method of sewing, can make filter bag prolong one times service life, the customer care cost obtains greatly to reduce.Under the nominal situation, do not adopt above-mentioned design and method of sewing, life-span of the filter bag was generally about 16 months, and dust emission is 50mg-100mg/m
3And adopt above-mentioned design method of sewing, life-span of the filter bag is about 30 months, and dust emission is reduced to 30mg-20mg/m simultaneously
