Background technology
At present, cement production enterprise production line kiln tail dust collecting system adopts the long bag of high-temperature low-pressure pulse bag dust collector more.Prior art (CN 202024594 U) has provided a kind of " rotary kiln high temperature dust collecting sleeve chamber outlet valve ", and it utilizes the mechanisms such as cylinder to control outlet valve.But the outlet valve of this kind of structural design still exists and opens, closes not in time, will directly cause flue gas to be bottled up in bag chamber cannot be expelled in rotary kiln blower fan from discharge nozzle, has a strong impact on the normal production of cement production enterprise.
Utility model content
For the technical problem existing in prior art, the utility model provides a kind of rotary kiln high temperature dust arrester installation, the outlet that this dust arrester installation can be realized between exhaust gas region and collecting zone opens and closes rapidly, and then making the dust collection effect of whole dust arrester installation best, production efficiency is high.
To achieve these goals, the technical scheme of employing is as follows:
A kind of rotary kiln high temperature dust arrester installation, comprise high temperature dust collecting sleeve, described high temperature dust collecting sleeve is provided with and is connected with preheater and for delivery of the feeding pipe of flue gas, be connected with kiln tail blower fan and for delivery of the discharge nozzle of gas after processing, in described high temperature dust collecting sleeve, include the collecting zone that is connected with feeding pipe and is provided with some collecting bags for the treatment of flue gas, be connected with discharge nozzle and process the exhaust gas region of gas afterwards for discharging, described exhaust gas region is placed in the top of collecting zone, between described exhaust gas region and collecting zone, be provided with a dividing plate with through hole, it is characterized in that: in described exhaust gas region, be provided with and present greatly, the rubber bellows of lower little shape, the tube wall of described rubber bellows is depression, the projection continuous adjacent shape of arranging, between the top of described rubber bellows and pressing plate, be closed state, bottom end opening also covers on the through hole of dividing plate, the tube wall depression position of described rubber bellows is provided with some for being communicated with the passage of rubber bellows medial and lateral.
The utility model can also further be realized by the following technical programs:
Further, described pressing plate is sheathed in the fixed bar that top is fixedly connected with high temperature dust collecting sleeve inside top.
Further, on described fixed bar, be arranged with spring, the two ends of described spring are resisted against respectively pressing plate top and high temperature dust collecting sleeve inside top.
Further, in described pressing plate, the position of walking of fixed bar is provided with sealing ring.
Preferably, described fixed bar is through the center of pressing plate.
Preferably, described through hole is placed in the center of dividing plate.
The utility model rotary kiln high temperature dust arrester installation, traditional air cylinder structure is modified into the structure that pressing plate and cone rubber bellows match, in the situation that there is air pressure in collecting zone, thereby jacking pressing plate is fully opened rubber bellows, then by being arranged at the passage at the tube wall depression position of rubber bellows, realize the current of air-flow, and the gas in exhaust gas region is expelled in rotary kiln blower fan by discharge nozzle.In addition, after collecting zone air pressure disappears, under the Action of Gravity Field of pressing plate, again by rubber bellows " flattenings ", thereby realization to the closing of passage, and then the gas channel between isolated collecting zone and exhaust gas region.And then making the dust collection effect of whole dust arrester installation best, production efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the local enlarged diagram at A place in Fig. 1.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
As a kind of preferred embodiment of the present utility model, refer to Fig. 1 and 2, a kind of rotary kiln high temperature dust arrester installation, comprise high temperature dust collecting sleeve 1, high temperature dust collecting sleeve 1 is provided with and is connected with preheater and for delivery of the feeding pipe 2 of flue gas, be connected with kiln tail blower fan and for delivery of the discharge nozzle 5 of gas after processing, in high temperature dust collecting sleeve 1, include the collecting zone that is connected with feeding pipe 2 and is provided with some collecting bags 4 for the treatment of flue gas, be connected with discharge nozzle 5 and process the exhaust gas region of gas afterwards for discharging, exhaust gas region is placed in the top of collecting zone, between exhaust gas region and collecting zone, be provided with a dividing plate 3 with through hole.
In exhaust gas region, be provided with the rubber bellows 10 that is upper big, lower small shape, the tube wall of rubber bellows 10 is depression, the protruding continuous adjacent shape of arranging.
Between the top of rubber bellows 10 and pressing plate 6, be closed state, bottom end opening also covers on the through hole of dividing plate 3.
The tube wall depression position of rubber bellows 10 is provided with some for being communicated with the passage 11 of rubber bellows 10 medial and lateral.
Under the rubber bellows 10 quilt states of " flattening " of taper, passage 11 cannot be communicated with the air-flow of rubber bellows medial and lateral; And under the complete deployed condition of rubber bellows 10,11 of passages are realized the air-flow that is communicated with rubber bellows 10 medial and lateral.
In order to make, pressing plate 6 rises, step-down operation is more steady, and to avoid run-off the straight, pressing plate 6 is sheathed in the fixed bar 8 that top is fixedly connected with high temperature dust collecting sleeve 1 inside top.
