Among the figure, 1, filter bag, 2, go up liner, 3, lower liner, 4, the bottom surface liner, 5, the bag end.
The specific embodiment
As shown in Figure 1, a kind of non-woven dedusting filter bag of the present utility model comprises filter bag 1 and strengthens liner.Filter bag 1 is pocket, and this reinforcement liner is used and the suture of filter bag 1 with material, makes and is connected filter bag 1 medial surface.This filter bag 1 usefulness non-woven material is made.This reinforcement liner is used with the woven cloths of filter bag 1 with material and is made.Because strengthening liner is woven cloths, its Air permenbility is apparently higher than non-weaving cloth, so the use of strengthening liner can not influence original dust removing effects of filter bag 1.The reinforcement liner that filter bag 1 medial surface is provided with can prevent that the deashing air-flow from directly impacting filter bag 1, thereby prolongs the service life of filter bag 1.
To strengthen the protection effect of liner in order improving, to strengthen the back side of liner and be close to filter bag 1 medial surface filter bag 1.Owing to strengthen the front of liner, just meet to the one side of deashing air-flow comparatively smoothly, directly blow to filter bag 1 inboard with the deashing air-flow and compare, the resistance that air-flow runs into obviously reduces, thereby plays the effect that cuts down the consumption of energy.
As a kind of preferred version, strengthen liner and comprise liner 2, lower liner 3 and bottom surface liner 4.Last liner 2 is connected filter bag 1 medial surface top; Lower liner 3 is connected filter bag 1 medial surface bottom; 5 inboards at the bottom of bottom surface liner 4 is connected bag.Owing to be subject to the position of deashing gas shock in the filter bag 1 and be at the bottom of filter bag 1 medial surface top, filter bag 1 medial surface bottom and the filter bag bag 5, so only the reinforcement liner is set at these three positions.Compare with the reinforcement liner is set in filter bag 1 total inner surface, adopt this preferred version can save material.
In actual use, the height of filter bag 1 is not fixed.For guaranteeing to strengthen the protective action of liner, the height of the height of last liner 2 and lower liner 3 is decided according to the height of filter bag 1.When filter bag 1 highly was less than or equal to 4000mm, the height of last liner 2 was less than or equal to 300mm, and the height of lower liner 3 is less than or equal to 300mm, and bottom surface liner 4 equates with 5 area at the bottom of the filter bag bag.When filter bag 1 height during greater than 4000mm, the height of last liner 2 is at least 500mm, and the height of lower liner 3 is at least 500mm, and bottom surface liner 4 equates with 5 area at the bottom of the filter bag bag.
When making non-woven dedusting filter bag of the present utility model, the top edge of last liner 2 is made simultaneously with filter bag 1 sack and is connected, the lower limb of last liner 2 and filter bag 1 medial surface are used to make with the suture of material with filter bag 1 and are connected, and wherein lower limb and filter bag 1 medial surface three sewer are connected to good.The top edge of lower liner 3 and filter bag 1 medial surface are used to make with the suture of material with filter bag 1 and are connected, and the lower limb of lower liner 3 is made simultaneously with 5 edge at the bottom of the filter bag bag and is connected, and wherein, top edge and filter bag 1 medial surface are connected to good with three sewer.The edge of bottom surface liner 4 is made simultaneously with 5 edge at the bottom of the filter bag bag and is connected.
Be close to filter bag 1 medial surface for strengthening last liner 2 and lower liner 3, on last liner 2 and lower liner 3, vertically evenly make and filter bag 1 several sutures, be connected with filter bag 1 medial surface with material.It is good that each bar suture adopts three sewer.Distance between each bar suture is good with 14.5mm to 15.5mm.Because the deashing airflow direction that is blown in the filter bag 1 is operation from top to bottom earlier, operation from bottom to top more then, this method of sewing can be so that air current flow.
When liner 2 and lower liner 3 are close to filter bag 1 medial surface on guaranteeing, use on bottom surface liner 4 and the suture of filter bag 1 with material, three sewer " ten " font is to strengthen at the bottom of bottom surface liner 4 and the filter bag bag 5 applying.
Facts have proved that use the technical solution of the utility model, under the state of jetting pressure 3kg to 8kg, airflow scouring gap 3min to 5min, filter bag prolongs 30% to 40% 1 service life.
