Abstract

The utility model discloses a bottom loaded filter bag and frame device for bag dust remover, comprising an upper cap, a frame and an expansion ring type filter bag. The expansion ring type filter bag is tightly clamped at the ceiling hole, and each inner wall at the both sides of the upper cap is provided with a through hole slot. The frame is provided with 3 pairs of steel wires at least to be its longitudinal skeleton filaments. Two pairs of steel wires are longer, while the others are shorter. The two pairs of steel wires are positioned in relative positions, and each head of the steel wire has a bending. The bending parts are inserted into the through hole slots. The width of the through hole slot is not less than the distance of the two longer steel wires, and the shorter steel wire has a distance with the upper cap. The utility model has the advantages of good sealing property, uneasy to break off, convenient and fast installation.

Description

Sack cleaner down-mounting type filter bag and frame mounting

Affiliated technical field

The utility model relates to the filter element of sack cleaner---and filter bag and framework, especially down-mounting type filter bag and framework belong to dirt or flue dust is prevented and kill off the field.

Background technology

The sack cleaner that current China uses adopts cluster filter bag structure mostly with down-mounting type filter bag and framework; Because many sack cleaners are because the restriction that is subjected to dust remover roof to change bag space must be adopted down-mounting type filter bag and framework; But the shortcoming of cluster filter bag structure maximum is exactly that binding place sealing is too poor, emits ash serious, even the phenomenon that filter bag comes off in addition occurs, and causes poor filtration effect, and the outlet dust concentration does not reach designing requirement.

The utility model content

The purpose of this utility model is to disclose a kind of novel filter element that is used for sack cleaner, a kind of down-mounting type filter bag and frame mounting, the use of this device can be stopped existing down-mounting type filter bag of sack cleaner and the existing above-mentioned defective of framework fully, and easy for installation fast and reliable.

The technical solution of the utility model is: this device is made of last cap, framework, filter bag, and filter bag is enclosed within outside the framework, it is characterized in that: described filter bag is the piston ring type filter bag, and this piston ring type filter bag tightly is stuck on the card hole; Respectively have long through-hole groove on the two side inwalls of described upward cap; Described framework has at least 3 pairs of steel wires as its vertical skeleton silk, wherein two pairs longer, all the other each to shorter, two pairs of longer steel wires are in relative position, the head of two pairs of longer steel wires has a bending, this bending part inserts in the described through-hole groove of going up cap, and the width of described through-hole groove is not less than the distance between adjacent two longer steel wires, between short steel wire and the last cap certain spacing is arranged.

The beneficial effects of the utility model are: because there is steel wire different in size in framework, the shorter steel wire that exceeds of two pairs of longer steel wires does not laterally bundle skeleton with top, the elasticity that relies on steel wire self to have, the upper end of longer steel wire is curving inwardly, its bending part that has can firmly block cap by the through-hole groove on the last cap, the recess that while also can make the piston ring of piston ring type filter bag form between the length steel wire obtains compression, and the card endoporus of packing into smoothly, and rely on the tension of its piston ring and be stuck in tightly on the card endoporus.The utility model has adopted the piston ring type filter bag of the tight card of above-mentioned and card endoporus, good airproof performance, and the filter bag difficult drop-off, and whole device need not use bolting when installing, and also do not need other instruments auxiliary, and easy for installation quick.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Fig. 1 is the structural representation (front view) of preferred embodiment;

Fig. 2 is the partial enlarged drawing at A place among Fig. 1;

Fig. 3 is that this embodiment installs the preceding side view with respect to Fig. 1 of combination;

Fig. 4 is the schematic diagram of going up among Fig. 1 after cap 1 makes up with framework 2 (part);

Fig. 5 is the state diagram of the framework 2 among Fig. 1 will pack the through-hole groove of going up cap 1 into the time;

Fig. 6 is the side view with respect to the last cap 1 of Fig. 1.

Among the above figure: 1. go up cap, 2. framework, 3. card, 4. piston ring type filter bag, 5. through-hole groove

The specific embodiment

Shown in Fig. 1,3,4, last cap 1, framework 2, piston ring type filter bag 4 combine with card 3 and constitute a cover down-mounting type filter bag frame mounting, and the piston ring mouth outer shroud depression of piston ring type filter bag 4 is stuck on the endoporus of card 3.

The framework 2 of preferred embodiment is an octagon, has eight steel wires, wherein four longer, and head has the little bending in right angle, all the other four shorter.Four long steel wires become two pairs, and every couple two are adjacent and connect in the bending place with transverse support bar, and the longer steel wire of this two couple is in relative position.Form two recesses between length and the shorter steel wire.Exceed shorter steel wire with top because of there being the binding of horizontal skeleton, two pairs of elasticity that longer steel wire relies on steel wire self to have, its upper end is curving inwardly.

As shown in Figure 6, relative two sides of cap 1 have through-hole groove 5 on the circle, and the width of through-hole groove 5 is not less than the distance between adjacent two longer steel wires.

During installation, to go up cap 1 earlier places above the card 3, the piston ring type filter bag 4 that external diameter is cooperated with framework 2 is placed in outside the framework 2 again, pinch flat at two recesses of framework 2 piston ring of piston ring type filter bag 4, simultaneously the transverse support bar of two pairs of longer steel wires is inwardly pressed, piston ring type filter bag 4 and framework 2 are stretched in the hole of card 3 smoothly, the piston ring mouth of piston ring type filter bag 4 is stuck on the card hole, and in two through-hole grooves 5 with cap 1 in the bending part insertion of two pairs of longer steel wires, like this, last cap 1, framework 2, piston ring type filter bag 4 just are connected with card 3.Because the piston ring of piston ring type filter bag 4 adopts elastomeric material and attached lining encapsulant to make, and with cooperating of card hole be tolerance fit, so stretch in the card hole when piston ring and framework, in the time spent of doing that does not have external force, card is firmly blocked in its very fast ejection, has finished quickly and easily and has installed.

Claims

1. sack cleaner is made of last cap, framework, filter bag with down-mounting type filter bag and frame mounting, and filter bag is enclosed within outside the framework, it is characterized in that: described filter bag is the piston ring type filter bag, and this piston ring type filter bag tightly is stuck on the card hole; Respectively have a through-hole groove on the two side inwalls of described upward cap; Described framework has at least 3 pairs of steel wires as its vertical skeleton silk, wherein two pairs longer, all the other each to shorter, two pairs of longer steel wires are in relative position, the head of two pairs of longer steel wires has a bending, this bending part inserts in the described through-hole groove of going up cap, and the width of described through-hole groove is not less than the distance between adjacent two longer steel wires, between short steel wire and the last cap certain spacing is arranged.

2. down-mounting type filter bag as claimed in claim 1 and frame mounting are characterised in that: described framework has 4 pairs of steel wires as its vertical skeleton silk.
