Example one

Referring to fig. 1 to 4, the present invention provides an embodiment: the utility model provides a kiln head kiln tail dust arrester installation for cement manufacture, includes

casing

2, and 2 bottom welding of casing install first ring flange 1, and casing 2 adopts cylindric structural design, and 2 inner walls of casing are equipped with high temperature resistant coating. The housing 2 is easily mounted on the outlet opening of the exhaust gas line by providing the first flange 1. 2 tops welding installations of casing have second ring flange 7, and there is mounting bracket 8 second ring flange 7 top through installation screw 10 fixed mounting, and net section of thick bamboo body 4 has been placed to 8 inboard activities of mounting bracket, and 8 inboard and 4 outer wall tops of net section of thick bamboo body contact but not fixed connection of mounting bracket. Through the arrangement of the movably inserted net cylinder body 4, the net cylinder body 4 and the dust collecting cloth bag 3 can be conveniently taken out together for maintenance during maintenance. Through setting up net section of thick bamboo body 4 and placing net section of thick bamboo body 4 activity in mounting bracket 8 to when carrying out dismouting maintenance, can directly take out the dust collecting cloth bag 3 of suit on net section of thick bamboo body 4 and the net section of thick bamboo body 4 together from mounting bracket 8, reached the effect that makes things convenient for the dismouting maintenance.

Example two

Referring to fig. 1 to 4, the present invention provides an embodiment: the utility model provides a kiln head kiln tail dust arrester installation for cement manufacture, compares in embodiment one, and this embodiment still includes a net section of

thick bamboo body

4, and 4 outer wall covers of a net section of thick bamboo body are equipped with the sack 3 that gathers dust, and the sack 3 that gathers dust passes through clamp 5 fixed mounting on 4 outer walls of a net section of thick bamboo body. The dust collection cloth bag 3 is sleeved outside the net barrel body 4 through the hoop 5, so that dust is filtered and collected through the dust collection cloth bag 3. The top of the inner side of the net drum body 4 is fixedly provided with a fixed frame 9, and the cross section of the fixed frame 9 adopts a hexagonal structure design. Through the arrangement of the hexagonal fixing frame 9, filtered air in the exhaust pipeline is exhausted through the gap on the fixing frame 9. The fixed frame 9 is internally and fixedly provided with a recoil pipe 6. The pipe wall of the back flushing pipe 6 is provided with air outlet holes in an annular array, and the bottom end of the back flushing pipe 6 in the net cylinder body 4 is sealed. Through set up the venthole on the pipe wall of recoil pipe 6 to when gathering materials too much at the sack that gathers dust 3, the accessible injects highly-compressed air into recoil pipe 6, thereby conveniently carries out high-pressure clearance to the sack that gathers dust 3. Through setting up recoil pipe 6 to set up the venthole on 6 pipe walls of recoil pipe, thereby when the sack 3 that gathers dust is cleared up, the venthole on the high-pressure air accessible recoil pipe 6 is to the sack 3 that gathers dust and assault, thereby clears up the sack 3 that gathers dust, has reached the effect of conveniently discharging the dust.

The working principle is as follows: when the utility model is installed, the dust collecting cloth bag 3 is sleeved on the net cylinder body 4 through the hoop 5, the backflushing pipe 6 is installed in the net cylinder body 4 through the fixing frame 9, the shell 2 is communicated and installed on the air outlet hole of the exhaust pipeline through the first flange plate 1, the mounting rack 8 is arranged at the top of the shell 2 through the second flange 7, at the moment, the net drum body 4 is directly arranged in the mounting rack 8, when in use, gas with dust enters the shell 2, when the dust passes through the dust collecting cloth bag 3, dust in the air is stained on the outer wall of the dust collecting cloth bag 3, the filtered air is discharged through the gap on the fixed frame 9, when the dust collecting cloth bag 3 is excessively collected and the using effect is reduced, an air supercharging device communicated with the back flushing pipe 6 is started, thereby erode the sack body with high-pressure air through the exit vent on the recoil pipe 6 to erode the row material to the sack body.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
