Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: as shown in Figure 1, being a kind of pulse bag type dust collector disclosed by the utility model, including shell 1 and taper
Dust compartment 2.The bottom of dust compartment 2 is provided with mounting bracket 3, the top of shell 1 is provided with guardrail 4.
As illustrated in fig. 1 and 2, air-purifying chamber 11 is provided in shell 1, the side of air-purifying chamber 11 is communicated with wind pipe 112,
Wind pipe 112 is connected with negative-pressure air fan 113 far from one end of air-purifying chamber 11.Vertical baffle is fixed in air-purifying chamber 11
111, air-purifying chamber 11 in shell 1 is divided into inertia settling chamber 12 and filter chamber 13, the bottom of filter chamber 13 and inertia by baffle 111
Expansion chamber 12 is connected to, and is additionally provided with air inlet 121 on the side wall of inertia settling chamber 12.
As shown in Fig. 2, being equipped with card 5 in filter chamber 13, filter bag 6 is installed on card 5.As filtering operating condition is continuous
It carries out, the dust that product is attached on 6 surface of filter bag is also continuously increased, and correspondingly just will increase the running resistance of equipment.For guarantee group
The normal operation of part, it is necessary to carry out deashing to achieve the purpose that shake off the dust on filter bag 6, reduce equipment running resistance.Therefore,
As shown in Fig. 2, being additionally provided with pulse blowing component 7 in shell 1 comprising gas storage packet 71, several injection tubes 72 and several
Nozzle 73.The outer wall of shell 1 is provided with the fixed plate 14 for being horizontally arranged gas storage packet 71；Injection tube 72 is along gas storage packet 71
Length direction array is set to the top of card 5, and one end of injection tube 72 is connect by impulse electromagnetic valve 74 with gas storage packet 71, separately
One end passes through shell 1 and extends to the upside of 6 sack of filter bag, and nozzle 73 is set to the surface of each filter bag 6.Impulse electromagnetic valve
74 can be controlled by PLC and periodically be opened and closed, and the compressed air in gas storage packet 71 carries out anti-filter bag 6 by nozzle 73
Air flow blowing, 6 instantaneous expansion of filter bag is simultaneously acutely shaken, so that the dust for being attached to its surface is detached from rapidly and drops down onto dust
In storehouse 2 (referring to Fig. 1), and then filter bag 6 is made to keep preferable filter effect.Impulse electromagnetic valve 74 employed in the present embodiment by
The manufacture of Shanghai Huan Yong Self controlling valve Co., Ltd.
As shown in figure 3, in its inner sidewall, also circumferentially fitting is fixed with enforced loop plane 8 for protection 6 sack of filter bag.Adding
The central concave of side wall towards the filter bag 6 of strong ring flat-plate 8 has tabs 81, and the one end at tabs 81 towards 6 center of filter bag tilts down
20 ° -30 °, filtering mouth is formed between tabs 81 and the side wall of enforced loop plane 8.Filter bag 6 and compression can be isolated in enforced loop plane 8
Air directly contacts, and the setting for extending its service life, while filtering mouth also acts will not be because setting adds at 6 sack of filter bag
Strong ring flat-plate 8 and the effect that can not be filtered.Inclined tabs 81 can then play the role of water conservancy diversion and dust-break, in specific implementation process
In, it will lead to dusty gas if its tilt angle is too small and be difficult to enter in filter bag 6, if excessive will lead to of its tilt angle is led
Stream is poor with the effect of dust-break, comprehensively considers and sets 25 ° for the tilt angle of tabs 81.
As shown in figure 4, the axisymmetrical on enforced loop plane 8 along filter bag 6 is provided with mounting plate 9, mounting plate 9 and card 5 can
Dismantling connection carries out installation and removal to filter bag 6 to facilitate.Installation gap 51 is offered on card 5, mounting plate 9 is separate to be added
The side of strong ring flat-plate 8 is fixedly connected with U-shaped elastic slice 10, and side of the U-shaped elastic slice 10 far from mounting plate 9 is integrally formed with clamping block
101.The clamping slot 511 being embedded in for clamping block 101 is provided in the side wall of installation gap 51.When filter bag 6 is installed, U-shaped is first compressed
Elastic slice 10 is embedded in it in installation gap 51, and U-shaped elastic slice 10 can make clamping block 101 be embedded in clamping slot by the elastic force of itself at this time
In 511, the connection between mounting plate 9 and card 5 is realized with this.
Clamping block 101 is made to be detached from clamping slot 511 as shown in figure 4, U-shaped elastic slice 10 need to be compressed again when dismantling filter bag 6,
And entire U-shaped elastic slice 10 is respectively positioned in installation gap 51 at this time, operating space is smaller, therefore in U-shaped elastic slice 10 far from mounting plate 9
The side and top for being located at clamping block 101 is also integrally formed with crushing block 102, is evenly equipped with several for increasing on crushing block 102
The anti-skidding raised line 1021 of friction.U-shaped elastic slice 10 just can be compressed by squeezing crushing block 102 in this way, to facilitate filter bag 6
Dismantlement work.
As shown in figure 4, setting its cross sectional shape in ladder to make clamping block 101 be easier to be embedded in clamping slot 511
It is arc transition between shape and its adjacent side, clamping block 101 can be made by the architectural characteristic of clamping block 101 itself in this way
Cooperate with clamping slot 511 lighter；It is in simultaneously face contact between clamping block 101 and clamping slot 511, but also clamping block 101
Mutual wear phenomenon is not susceptible to clamping slot 511.
The implementation principle of above-described embodiment are as follows: dusty gas is fed through through air inlet 121 used by starting negative-pressure air fan 113
Property expansion chamber 12 in, in air-flow biggish grit can by self weight drop down onto dust compartment 2, then the air-flow is using filter chamber 13
Secondary filter is carried out, final clean air-flow is discharged from air-purifying chamber 11 and wind pipe 112.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
