Abstract
The utility model relates to an arc-shaped bag opening structure of a single bag of a bag type filter. The bag opening is composed of two sections of sloping shoulders, a section of arc-shaped concave collar and two sections of straight edges in the closed state, wherein, a section of arc-shaped concave collar is positioned in the center of the bag opening, the two sections of sloping shoulders are respectively positioned at both ends of the bag opening, and the sloping shoulders and the concave collar are connected mutually through the straight edges, therefore to form a bag opening structure which is laterally symmetrical. Because the opening of the bag opening is reasonable in the arc-shaped bag opening structure after the bag opening is assembled, the resistance force to wind is reduced during the use, and effective filtering area of the filter bag is guaranteed, and the service life is increased. In addition, the initial resistance force is low and the resistance force increases slowly when the arc-shaped bag opening structure is used.
Description
Technical field
The utility model belongs to the air purifying process field, particularly a kind of bag filter monolithic bag arc pocket configurations.The bag filter that makes with this monolithic bag can be used for precise electronic industry, hospital, pharmaceutical factory and automobile factory's paint spray booth etc. as first, effect air cleaner.
Background technology
Bag filter is a kind of air cleaner that is made of a plurality of monolithic filter bags and framework.The air that contains micronic dust enters each filter bag from the bag filter inlet under pressure, because actings in conjunction such as sieving, inertial collision, interception, diffusion and gravitational settling, the filter cloth that micronic dust is filtered bag captures, and separates from air-flow, and clean air continues to flow.Bag filter is simple in structure, is the frequent species of air cleaner, its filtration mainly be rely on fiber on the filter cloth at dust through out-of-date, by tackling, touch with Fan Dehuali dust be adsorbed on the filtrate fiber surface.Because the dust that is captured increases in time gradually, the gap reduces between fiber, and the filtration resistance when air flows through increases, and when the filter bag inside and outside differential pressure surpasses specified resistance, is considered as cloth envelop collector and loses efficacy.In order to guarantee ventilation, reduce energy consumption, when filter bag reaches specified resistance, need to change filter usually.
The filter bag that has bag filter now is divided into circular bag, oval bag and flat bag three kinds by section configuration, wherein flat bag connects edge sealing by hot melt or sewing process with its three limits by two identical shaped overlapping backs of bag sheet and forms, and stays the sack of an opening as filter bag.In the prior art, the sack of the flat bag of monolithic is flat outlet structure under closure state, adopt the rectangle inside casing to strut sack during assembling from the inboard, this moment since flat mouthful under softened state, transfer stereochemical structure to, inwardly heave (as shown in Figure 1) after causing the bagging fold of sack below.The problem one that this phenomenon is brought at work is that the open air drag of sack is big, the energy consumption height, the 2nd, sack opens latter two adjacent filter bag pleated portions and overlaps (as shown in Figure 2), lap can not play a role in filtering, thereby filter area reduces, initial resistance increases, and shorten service life.
Summary of the invention
The utility model provides a kind of bag filter monolithic bag arc pocket configurations, and purpose is to solve the existing flat outlet structure of monolithic bag fold behind the suit inside casing to form and heave the sack that is brought and open that the big and adjacent filter bag fold of resistance is overlapping to cause the problem that filter area reduces, shorten service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bag filter monolithic bag arc pocket configurations, it is characterized in that: sack is made up of one section recessed neck of arc and two sections straight flanges under closure state, wherein, one section recessed neck of arc is positioned at sack central authorities, two sections straight flanges lay respectively at the two ends of the recessed neck of arc, constitute symmetrical sack structure with this.
1, in the such scheme, sack comprises two sections tiltedly shoulders under closure state, two sections tiltedly shoulder lay respectively at the sack two ends, tiltedly be connected by straight flange between shoulder and the recessed neck of arc.
2, in the such scheme, tiltedly the length of shoulder is that sack opens half of width.
3, in the such scheme, the chord length of the recessed neck of arc be sack open length 1/3rd to 4/5ths.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, since the utility model open rationally at sack assembling back sack, thereby when reducing to use to the resistance of wind, and guaranteed the effective filtration area of filter bag to have improved service life.
2, the utility model is rational in infrastructure, makes simply, and initial resistance is low during use, and resistance rises slow.
3, the utility model is compared for the flat bag of the monolithic of flat outlet structure under closure state with sack, the bag filter initial resistance A1 point of making is little, and arriving the time that specified resistance B orders extends to D days by the original C sky, (as shown in Figure 3), thus prolong service life.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: bag filter monolithic bag arc pocket configurations
Shown in accompanying drawing 4, accompanying drawing 5, accompanying drawing 6 and accompanying drawing 7, a kind of bag filter monolithic bag arc pocket configurations, sack 9 is tiltedly takeed on 1, one section recessed neck 2 of arc and two sections straight flanges 3 by two sections and is formed under closure state, wherein, one section recessed neck 2 of arc is positioned at sack 9 central authorities, two sections tiltedly shoulder 1 lay respectively at sack 9 two ends, tiltedly take on 1 with the recessed neck 2 of arc between be connected by straight flange 3, constitute symmetrical sack 9 structures with this.Wherein, tiltedly takeing on 1 length is that sack opens half of width.The chord length of the recessed neck 2 of arc be sack open length 1/2nd, tiltedly shoulder can be straight line, because length is shorter, also can be camber line.
Embodiment two: bag filter monolithic bag arc pocket configurations
A kind of bag filter monolithic bag arc pocket configurations, sack 9 is made up of one section recessed neck 2 of arc and two sections straight flanges 3 under closure state, and the recessed neck 2 of arc is positioned at sack 9 central authorities.The difference of present embodiment and embodiment one is not tiltedly shoulder 1.
