Fig. 2 is the A-A profiles of Fig. 1；
Fig. 3 is the structural representation of deduster group.
Specific embodiment
Fig. 1 is the structural representation of utility model；Fig. 2 is the A-A profiles of Fig. 1.With reference to shown in Fig. 1 and Fig. 2, Yi Zhongchao
Negative pressure dust removing device, including shell 10, top board 1, dividing plate 2, ash bucket 3, filter cylinder 4, high pressure gas pulse jetting deashing device 5, air inlet 6
With gas outlet 7, air-purifying chamber 8 is formed between top board 1 and dividing plate 2, dust-filtering room 9, shell 10 are formed between dividing plate 2 and ash bucket 3
It is cylinder, ash bucket 3 is turbination, ring stiffener 20 is respectively provided with the bottom of top board 1 and dividing plate 2, in top board 1 and dividing plate
Airtight passage 30 is set between 2, and airtight passage 30 goes directly dust-filtering room 9 from air inlet 6 through whole air-purifying chamber 8.In shell
10th, uniform some connection straps 40 between ring stiffener 20, airtight passage 30.
The width D of ring stiffener 20 is 6mm~12mm, and height H is 50mm~80mm；The width d of connection strap 40 is 6mm
~12mm, height h are 50mm~80mm, and connection strap 40 is at least 3, between the present embodiment shell 10 and ring stiffener 20
Connection strap 40 is 5, and the connection strap 40 between ring stiffener 20 and airtight passage 30 is 5.Net gas is set on dividing plate 2 to go out
Gas port 2.1；Air inlet pipe valve 11 is set on the admission line being connected with air inlet 6；In ash bucket 3, ash discharge valve 12 is set.
Deduster of the present utility model makes the anti-of deduster side using the shell 10 of cylinder and the ash bucket 3 of cone
Pressure property is greatly enhanced, and is increased between ring stiffener 20, and shell 10 and ring stiffener 20 by top board 1 and dividing plate 2
Some connection straps 40 and some connection straps 40 between ring stiffener 20 and airtight passage 30 be staggered, and top board 1
By the connection reinforcement of airtight passage 30 and dividing plate 2 between, so, the top board 1 and dividing plate 2 of deduster are obtained and deduster circle
The same bearing capacity of shell 10, greatly enhances the crushing resistance of deduster, so that off-line type deduster can effectively meet
The dust removal requirement of super subnormal ambient, effectively realizes the effect of high-effective dust-removing cleaning air.
Fig. 3 is the structural representation of deduster group.As shown in figure 3, when the utility model is used for central dust suction cleaning systems
One embodiment, the embodiment composes in parallel deduster group including three dedusters of the present utility model, and the present embodiment is each
Outlet tube valve 13 is set on the outlet pipe that deduster is connected with gas outlet 7, and certainly, each deduster can also be not provided with outlet
Tube valve 13, only sets air inlet pipe valve 11.When each deduster dedusting needs to carry out for a period of time " offline pulse jetting deashing ",
The air inlet pipe valve 11 of this deduster is closed, deduster is internally formed the immobilising Static-state Space of air-flow, now this removes
The ash discharge valve 12 of dirt device closed can unload the function of ash due to possessing, therefore, to be also in air-tight state；This deduster goes out
Tracheae valve 13 may be at closed mode, it is also possible in opening.It is then turned on high pressure gas pulse jetting deashing device 5
Filter cylinder 4 is carried out " offline pulse jetting deashing "；After being blown one section of cycle time and waiting one section of interval time, this is opened
The air inlet pipe valve 11 of deduster proceeds online dedusting work.Now outlet tube valve 13 will also be in opening.When
So, each deduster can also be not provided with outlet tube valve 13, only set air inlet pipe valve 11, so move in circles, and make deduster
Group can be carried out continuously dedusting work, realize the binary dedusting of filter cloth+ultraproduct rack-layer.Purpose using three dedusters is,
All the time having two dedusters carries out online dedusting, effectively can uniformly bear under super condition of negative pressure to deduster and the pressure of filter cylinder
Power.
In a word, the utility model saves deduster manufacture material under the conditions of equal compression strength, not only, and improves
The security performance of deduster.When being applied to the super negative pressure system dedusting of particular/special requirement, such as caliber is high less than 200mm, wind speed
Up to negative pressure value >=25KPa that 20m/s~50m/s, pipeline central dust suction cleaning systems long, its dust pelletizing system need；This practicality
New first can realize binary dedusting technology, effectively improve efficiency of dust collection；Second can save dust remover resistance power consumption values
30%~60%；3rd can extend consumptive material life-span >=1 times.
