Abstract

The invention relates to a round framework for a bag dust collector, which is characterized in that a compact spring wound by a plurality of circles of plastic steel wires with the diameter of 2-6 cm instead of a spring steel wire; the outside diameter of the spring is equal to the inside diameter of a bag; and the round framework is put into the bag after elongated in use. Compared with the prior art, the round framework for a bag dust collector only uses a common steel wire and merely needs one machining procedure, has low cost, is one tenth to one thirtieth of a hard framework in volume in transportation, is convenient to use on site only by being put into the bag after elongated, is convenient to take out, and is simple, easy and convenient for manufacture, transportation, use and maintenance.

Description

The circular skeleton of sack cleaner

[technical field]

The invention belongs to the environmental protection equipment sack cleaner, relate in particular to the circular skeleton of a kind of sack cleaner.

[background technology]

Existing sack cleaner has rigid and soft two kinds with circular skeleton; The structure of so-called rigid skeleton is to be the steel wire of 4～6 millimeters, length and cloth bag equal in length with 6～12, diameter; Make a plurality of annulus with same steel wire in addition, the diameter of annulus is approximately less than 1 centimetre of cloth bag diameter; Then these long steel wires evenly are distributed and are welded on by circumference on the outer rim of annulus, annulus is approximately every half meter one; Each skeleton is an integral body, and it is 8 meters that present its length the shortest of using is 2 meters the longest; The defective of this skeleton is a processed complex cost height, need be stretching, do operations such as ring, shearing, welding steel wire, and deduster is installed in and requires when indoor dust remover roof that upper space with the skeleton equal in length will be arranged.

So-called soft skeleton is exactly the spring skeleton, and actual is exactly the extension spring that double headed roller colludes, and during use spring is placed in the cloth bag, is hooked on it on sack, and the spring other end is pulled down out in cloth bag, colludes down to hang on the girder of bottom at the bottom of passing cloth bag; Its advantage is that processing is simple, and shortcoming is up and down drop in beam link or hanging hole to be arranged, and wants Durchgangshohle at the bottom of the cloth bag, and must enter when changing cloth bag is the deduster inside of dust entirely, causes the installation and maintenance difficulty.

[summary of the invention]

For overcoming existing skeleton above shortcomings, the present invention aims to provide a kind of novel skeleton simple, with low cost of processing.

The technical scheme that addresses the above problem: with diameter is that 2～6 millimeters plasticity steel wire is neither the tight spring that the spring steel wire coiled is made up of multi-turn key silk, the spring external diameter equals the cloth bag internal diameter, to put into cloth bag after its elongation during use, the length after the elongation equals the cloth bag length.

Beneficial effect: compare with existing skeleton, the present invention only uses ordinary steel wire, and as long as one manufacturing procedure---coiling is processed extremely simple, with low cost; Its volume is equivalent to ten to a thirtieth of rigid skeleton during transportation, elongates when using at the scene, puts into cloth bag and gets final product, and it is convenient too to take out, and dust remover roof is large space very; Its manufacturing, transportation, use, maintenance are all simple, easy, convenient.

[description of drawings]

When using for the embodiment of the invention, Fig. 1 draws back figure;

Fig. 2 makes to finish figure.

[specific embodiment]

Referring to Fig. 1 Fig. 2.According to the size of cloth bag diameter, be that 2～6 millimeters plasticity steel wire is neither the tight spring that the spring steel wire coiled is made up of the multi-turn steel wire is seen Fig. 2 with diameter; During use it is elongated, apart from being about 2～10 centimetres, putting into cloth bag again and get final product between the two adjacent rings steel wire of elongation back, see Fig. 1.

The specific embodiment one

The cloth bag diameter is 120 millimeters, when length is 2 meters, the spring external diameter also is 120 millimeters, steel wire diameter is 3 millimeters, number of total coils is 51 circles, drawing back back two adjacent rings key silk spacing is 40 millimeters.

The specific embodiment two

The cloth bag diameter is 300 millimeters, when length is 8 meters, the spring external diameter also is 300 millimeters, steel wire diameter is 6 millimeters, number of total coils is 81 circles, drawing back back two adjacent rings key silk spacing is 100 millimeters.

Claims

1. the circular skeleton of sack cleaner is characterized in that: with diameter be 2～6 millimeters plasticity steel wire neither the tight spring that the spring steel wire coiled is made up of the multi-turn steel wire, the spring external diameter equals the cloth bag internal diameter, during use it is put into cloth bag after elongating.
