With reference to shown in Figure 1, a large amount of low pressure blowing gas that roots blower produces enter in the gas bag 1 via last air inlet hollow shaft 61, following air inlet hollow shaft 62.When system's internal pressure surpasses 0.8bar, the safety valve pressure release on the roots blower, shutdown; When system's internal pressure was lower than 0.6bar, roots blower started air feed again.
Before the jetting deashing function on, described winding-up pipe 7 matches with the regional A of the winding-up on the described card 8, and the position of described passage 31 as shown in Figure 6A.Behind the jetting deashing function on, second drive motors 41 drives second driving sheave 421 and finishes the rotation in first week, and by second driven sheave 422 and connect firmly following air inlet hollow shaft 62 on second driven sheave 422, drive valve plate 3 and rotate 36 ° (position of the passage 31 shown in Fig. 6 B), at this moment, boss portion 125 on the passage 31 corresponding gas bag top covers 12 on the valve plate 3, gas bag 1 not exhaust is only inflated from roots blower, and then finishes the inflation operation.Subsequently, second drive motors 41 drives second driving sheave 421 and finishes the rotation in second week, corresponding valve plate 3 rotates 72 ° (position of the passage 31 shown in Fig. 6 C), at this moment, passage 31 on the valve plate 3 is radially identical in 0.2～0.3 second time with the injection hole 122 on the gas bag top cover 12, a large amount of blowing gas in the gas bag 1 are via winding-up pipe 7 and chain induction pipe 71, spray in the filter bag 81 for the treatment of deashing, and produce one balanced from top to bottom outside shock wave in the total length of filter bag 81, make the filtrate of whole filter bag 81 finish the deashing that the expands outwardly motion of a general equilibrium, simultaneously, a large amount of low pressure blowing gas finished a general equilibrium expand outwardly motion after, some low pressure blowing gas can penetrate the filtrate of filter bag 81, finish the secondary deashing operation of the filtrate deep layer that pulse jetting deashing mechanism can't realize, and then finish a jetting deashing operation.
After the jetting deashing operation of the regional A of winding-up is finished, first drive motors 21 drives first driving sheave 221 and finishes the rotation in first week, by first driven sheave 222, upward air inlet hollow shaft 61 drive valve plate bearing supports 5 and gas bag 1 rotation, and described gas bag 1 is in the location of supporting positioning seat 91 and a plurality of revolution rollers 92, supporting is rotated 72 ° together with described winding-up pipe 7 down, makes the chain induction pipe 71 that is connected with on the described winding-up pipe 7 turn to the position of matching with the area B of jetting from the position of matching with the regional A of winding-up respectively.Then, repeat above-mentioned 5 inflation operations and 5 jetting deashing operations, what make filter bag 81 in the winding-up area B all finishes the deashing operation.At this moment, first drive motors 21 drives first driving sheave 221 and finishes the rotation in second week, described gas bag 1 rotates 144 ° together with described winding-up pipe 7, described winding-up pipe 7 turns to the position of matching with the zone C of jetting, repeat above-mentioned 5 inflation operations and 5 jetting deashing operations again, make filter bag 81 whole of winding-up zone C finish the deashing operation, Zhou Erfu it, drive first driving sheave 221 until first drive motors 21 and rotated for five weeks, after gas bag 1 rotates 360 °, make the filter bag in 5 winding-up zones that are arranged on the card 8 all finish the deashing operation 81 1 groups by one group, so far finish the jetting deashing operation of one-period.
It is 4KW that the utility model can adopt power of motor, and blast is 0.6～0.8bar, and air quantity is 80～120M
3The double leaf of/H, three leaf roots blowers are as air supply device, and the winding-up air quantity that the utility model produced is 5 times of pulse jetting deashing mechanism, therefore, the utility model not only can be removed the dust of filtrate deep layer, improve the effect of jetting deashing, can also increase effective deashing length of winding-up, be applicable to jet clear dirt of long filter bag is handled.For example, directly be the filter bag of φ 130mm for bag, effective deashing length of the present utility model can reach 11m.Therefore, under the situation of effective deashing given volume, to compare with known technology, the utility model can satisfy the deashing operation to the general equilibrium of long filter bag, thereby can correspondingly reduce the radial dimension of filter bag in the deduster, make the floor space of sack cleaner reduce about 30%.
Low pressure multistation direct injection deashing device of the present utility model is compared with conventional pulse jetting deashing mode, can save 80% energy.
Present embodiment mainly is with the difference of embodiment 1: first driven sheave of present embodiment directly is connected with the valve plate support.
As shown in Figure 8, described first driven sheave 222 of present embodiment is directly fixedlyed connected with described valve plate support 5, makes directly drive valve plate support 5 rotations of described first driving mechanism 2, and then drives gas bag 1 rotation; Air inlet hollow shaft 6 passes the air admission hole 121 and upper and lower layer support 51,52 of gas bag top cover 12 simultaneously, and be pivoted mutually in described valve plate support 5, the upper end of described air inlet hollow shaft 6 is connected by sealing return bend joint 64 with the discharge pipe of air supply device 63, and the lower end penetrates in the described gas bag 1 and fixes with valve plate 3.The part of air inlet hollow shaft 6 between upper and lower layer support 51,52 fixes with second driven sheave 422, rotates with respect to described gas bag top cover 12 so that described second driving mechanism 4 can drive described valve plate 3.
The structure of present embodiment, the combination of having saved between the upper and lower air inlet hollow shaft 61,62 is installed, and has further simplified deashing device of the present utility model, has improved the utility model security and reliability in the course of the work.
Other structure, operation principle and the beneficial effect of present embodiment is identical with embodiment's 1, at this, does not do and gives unnecessary details.
The above, it only is specific embodiment of the utility model, be not in order to limiting scope of the present utility model, i.e. equivalent variations and the modification of doing according to the utility model claim and description generally all should still belong in the scope that the utility model patent contains.
