In case 42, and multiple filter bags 422 are evenly distributed in the dust cleaning case 42, and are connected by gas blow pipe and the partition plate 421
It is logical.Treat that hopper 1 enters the gas with dust of the hopper 43 from the bottom to top by multiple filter bags from the aggregate
422, the material of the filter bag 422 has cotton fiber, wool fibre, synthetic fibers and glass fibre etc., can adsorb in air
Dust, plays the role of filtering.
The pulse backblowing deduster 4 further comprises deashing device 47, and the deashing device 47 is arranged on the dedusting
On the lateral wall of case 42, the deashing device 47 includes tracheae 471, electromagnetic impulse valve 472 and air accumulator 473, the tracheae 471
Both ends connect the air accumulator 473 and the dust cleaning case 42 respectively；The electromagnetic impulse valve 472 is arranged on the tracheae 471,
For controlling the break-make of tracheae 471.After the pulse backblowing deduster 4 works a circulation, adsorbed on the filter bag 422
Certain dust, can play the role of the filter bag 422 deashing with deashing device 47 at this time, and dust falls to the hopper 43,
Entered in affiliated mixer 3 and recycled by the vomit pipe 45.The air accumulator 473 is used to store compressed gas
Body, when needing to carry out deashing, opens the impulse electromagnetic valve, the compressed gas in the air accumulator 473 can be with the gas
Pipe 471 is entered in affiliated dust cleaning case 42, and compressed gas expands, and is blown the filter bag 422 so that on the filter bag 422
Dust fall in the hopper 43, and enter in the mixer 3 and recycle along the vomit pipe 45.
Preferably, the dust cleaning case 42 further comprises bronchus road 423, and the bronchus road 423 is arranged on the partition plate
421 tops, the bronchus road 423 are connected with the tracheae 471, and the compressed gas enters described from the tracheae 471
In bronchus road 423 so that gas compression uniformly can carry out deashing to each filter bag 422.
4 side wall of pulse backblowing deduster is equipped with inspection door 48, can open closure, during for checking one section of work
Between after the filter bag 422 absorption situation, and as needed, replace filter bag 422 in time.
The power of the air-introduced machine 44 is 1.9KW-2.4KW.Preferably, the power of the air-introduced machine 44 is 2.2kw.If institute
State that the power of air-introduced machine 44 is too small, then it is smaller to the suction of the gas, it is impossible to which that guarantee preferably draws the aggregate and waits to expect
The gas with dust in bucket 1；If the power of the air-introduced machine 44 is excessive, treat that the suction of hopper 1 is excessive to the aggregate,
It not only cannot preferably treat that the dust in hopper 1 carries out dedusting to the aggregate, can be caused on the contrary due to larger suction described
Aggregate treats that the dust in hopper 1 is more.Power parameter and mixer parameter and it is corresponding selected by deduster relating to parameters.
The hopper 43 includes the first opening 433, and the diameter of first opening 433 is more than the straight of the discharge port 431
Footpath, first opening 433 are connected with the lower end of the dust cleaning case 42, one end of the discharge port 431 and the vomit pipe 45
Connection.Since the diameter of the described first opening 433 is more than the diameter of the discharge port 431, then the hopper 43 is in reverse tapered shape,
Fall in the mixer 3 and recycle along 43 side wall of hopper easy to dust.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
The spirit of utility model and any modification, equivalent substitution, improvement and etc. within principle, done, should be included in the utility model
Within the scope of protection.
