Abstract

The utility model relates to a tube-like filter screen duster. A filter screen which is folded into a star shape is fixed on a filter net supporting frame, so that a filter tube is formed; a circular hole is arranged on the box body of the duster, and an automatic positioning device for an elastic clamp is arranged along a hole channel in the circular hole; the filter tube which is inserted into the circular hole can be positioned by the automatic positioning device for an elastic clamp, so that dusty gas can enter from the outside of the filter tube, and purified gas can be exhausted from the core part of the filter tube. The utility model has the advantages of small size, convenient maintenance and replacement, high dust removing efficiency, good sealing performance, etc., and is an ideal substitute for bag dusters.

Description

Tube-like filtering-screen dustor

The utility model belongs to the deduster field, is specifically related to a kind of cartridge type filter screen deduster.

At present, the wide model of fiber bag precipitator is applied in the occasion of reuse after the purification of dusty gas of factory or discharging, and efficiency of dust collection is higher, and the dust of regaining as industries such as pharmacy, cement, flour, rare metals also has certain value; In addition, fiber bag precipitator good seal performance efficiency of dust collection can reach more than 99%, thus it at home and abroad used as a kind of cleaner by wide model, but fiber bag precipitator exists the problem of following several respects:

1. it is very low to filter cigarette speed, and in 1m/min, so floor space is big;

2. need main frame to stop transport when changing cloth bag, the intrinsic cloth bag of dismounting deduster can keep in repair, and is therefore time-consuming, not only dirty but also tired, both endangered the healthy of maintainer, increased the maintenance operating cost again, thereby some unit stops using for this reason;

3. cloth bag is afraid of moistly, meets high-temperature flue gas dewfall or dust humidity, will cause the cloth bag caking and scraps;

4. adopt craft or welding assembly, precision is lower, so the air leak rate of air curtain height has had a strong impact on efficiency of dust collection.

The cartridge type filter screen deduster that the purpose of this utility model provides little, the easy replacing of a kind of floor space, need not shut down when changing.

This cartridge type filter screen deduster, by deduster casing 4, lock grey device 5, support 6, Pressure gauge 7, dusty gas inlet 8, purified gas outlet 9, go out ash bin 10 compositions such as grade, it is characterized in that being fixed on after filter screen 11 folds and form filter cylinder 1 on the screen support frame 13, its cross-sectional area of filter screen after folding is a hub-and-spoke configuration, have circular hole on the deduster casing, along the duct cartridge clip automatic positioning equipment 3 is fixed on the circular hole of intermediate plate 15 in the circular hole, filter cylinder 1 inserts cartridge clip automatic positioning equipment 3 location, dusty gas is discharged from an end of filter cylinder by filter screen 11, the other end is by cartridge head 2, sealing ring 12, filter cylinder blind patch 14 is fastened on filter cylinder on the casing, and intermediate plate 15 forms purified gas outlet 9 with casing 4.Cartridge clip automatic positioning equipment 3 is connected as a whole it with cross bar 18 along circumference is axial arranged by rib 17, is fixed with cartridge clip jump ring 16 on the rib of positioner 3.The filter material that filter screen is moisture-proof, be not afraid of washing, antistatic constitutes.

Use this deduster to have following advantage:

1. because the screen support frame adopts core structure, and filter screen is fixed on the cylindrical shell, the deduster body and the cartridge clip automatic positioning equipment is arranged of then packing into can be guaranteed accurately to put in place, and repair and replacement are very convenient, need not shut down during replacing;

2. because the cross section of filter screen is a hub-and-spoke configuration, has increased filter area, thereby significantly reduced floor space;

3. because the core structure good seal performance obviously improves efficiency of dust collection;

Since filter screen be moisture-proof, the filter material formation of not being afraid of washing, antistatic, so the range of application of sack cleaner will be more extensive.

Embodiment of the present utility model is referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4.

Fig. 1 is the perspective view of the horizontally disposed filter cylinder of cartridge type filter screen deduster;

Fig. 2 is the perspective view of filter cylinder;

Fig. 3 be the A--A of Fig. 2 to cutaway view, show the hub-and-spoke configuration of filter cylinder;
