Abstract

The utility model relates to a dust removing device for a cement mill electric dust-collector, which is used for removing cement and ash deposit on an electrode surface in an electric dust-collector. The utility model is composed of a T-shaped brush holder, a chain, a chainwheel, a pulley, a drive shaft, a worm gear and worm mechanism, etc., and the utility model is arranged in the inner part of the electric dust-collector. So long as an operating button is pressed once, the T-shaped brush holder can be moved up and down along the electrode surface to remove the ash deposit once, and thereby, the electric dust-collector can be ensured to run for a long time under a high efficient. The utility model has the advantages of reliable ash removing and convenient use.

Description

The brush dust device of cement grinding mill cottrell

The utility model is the electrode brush dust device that the cement grinding mill cottrell of manufacture of cement factory is used.

Many manufacture of cement of Xu producer for preventing to pollute and the cement dust loss, has all adopted cottrell, but, the cement flour ash that is adsorbed on electrode surface is not easy to remove very much, and the cement dust stratification just has a strong impact on dust-collecting efficiency after piling up, and powerful mechanical vibration method is adopted in some cement plants; The electric and magnetic oscillation method; Electric spark or ultrasonic wave blast impact and vibration method carry out ash disposal to electrode surface, and effect is all undesirable.

The purpose of this utility model is to provide a kind of brush dust device of cement grinding mill cottrell, and it is reliable to the electrode surface ash disposal, and is easy to use.

The purpose of this utility model is to realize like this, the brush dust device of this cement grinding mill cottrell, by  shape brush holder, chain, sprocket wheel, pulley, part such as power transmission shaft, worm-and-wheel gear is formed, the two ends of  shape brush holder are connected with two chains respectively, chain is by sprocket wheel and pulley location, and the worm gear that sprocket wheel is provided with on the power transmission shaft with worm-and-wheel gear links.The width of  shape brush holder and the distribution of bristle are all relevant with the position distribution of electrode, and bristle all can closely be contacted with electrode surface.Worm-and-wheel gear is driven by a reversible motor. shape brush holder is parked in uppermost position in fig-ure when not using, do not influence the dust-absorbing function of electrode, and brush holder is provided with travel switch in uppermost position in fig-ure and upper/lower positions place.

When needs use this brush dust device, as long as one by handling push button, motor is just changeing the drive worm gear, and------sprocket wheel--chain-- shape brush holder moves down brush dust to power transmission shaft to worm screw, cement dust is brushed to be collected in the dust hopper, when  shape brush holder moves to upper/lower positions, touch lower stroke switch and make the transmission current reversal, so  shape brush holder upwards returns, touch upper stroke switch and make current interruption when returning to the extreme higher position, brush holder stops.So whenever by a push button, one of  shape brush holder work back and forth.

Brush dust device of the present utility model is arranged on electric cleaner inside, just works once by once handling push button.In case of necessity, can control the push button work of handling, realize regularly automatically removing the cement dust of electrode surface with computer, with the efficiency of dust collection of maintenance cottrell,

Characteristics of the present utility model are: ash disposal is reliable, and is easy to use.

Embodiment further narrates below in conjunction with accompanying drawing.

Accompanying drawing 1 is for being used for the electrode brush dust schematic representation of apparatus of the present utility model of 5M2, cottrell.

Among the figure: 1- shape brush holder 2-chain 3-sprocket wheel

4-pulley 5-power transmission shaft 6-worm-and-wheel gear

7-electrode fixed mount 8-dust hopper

Only the locations of structures schematic diagram of a row  shape brush holder among the figure, in the electric field of cottrell, will be according to flue gas " passage " quantity of electric field, the several rows of brush of packing into, the and arranged on left and right sides of each passage is respectively adorned a row, therefore, the cottrell of two electric field six passages is adorned brush 24 rows altogether, about the width 2400mm of every row brush frame, the anode bristle is pig palm fiber and small part nylon yarn, staple length 45mm, what the negative electrode bristle was used is nylon yarn, (60-80mm, operating position shows that this bristle can normally use to staple length in 100 ℃ of left and right sides high temperature of exhaust environment.Selected motor power (output) is 0.25KW, and the translational speed of brush holder is 50mm/ second.

Claims

The brush dirt device of cement grinding mill cottrell, by  shape brush holder chain, parts such as sprocket wheel, pulley, power transmission shaft, worm and gear are formed, and it is characterized in that: the both sides of  shape brush holder connect with two chains respectively presses, chain is by sprocket wheel and pulley location, and the worm gear that sprocket wheel is arranged on the power transmission shaft with worm screw links.
