Description
(1) technical field
The present invention relates to a kind of device for rectifying deviation of dehydrator filter cloth.
(2) background technology
Dewaterer is widely used in industries such as flue gas desulfurization, chemical industry, metallurgy, and dehydrator filter cloth is easy sideslip when operation, if rectifying effect is bad, can cause shutdown, even damages filter cloth, has a strong impact on the normal operation of dewaterer.
At present, the device for rectifying deviation of dehydrator filter cloth of use is many, and parts are many by signal of telecommunication control, and the trouble point is many, and reliability is low; The correction roller does not have the spread effect; Or adopt single touching lever, and filter cloth contacts touching lever all the time, and is big to the filter cloth damage, air bag or cylinder operating frequency height, and service life is short, the operation expense height.
(3) summary of the invention
Technical problem to be solved by this invention provide a kind of have highly sensitive, operation expense is low, the device for rectifying deviation of dehydrator filter cloth of high reliability.
Described device for rectifying deviation of dehydrator filter cloth, comprise sensing element, rectifying cylinder, correction roller, rectifying cylinder is connected with correction roller one end by piston, sensing element is connected with rectifying cylinder through valve, described sensing element comprises first touching lever, second touching lever that is installed in the dehydrator filter cloth both sides, described rectifying cylinder comprises first rectifying cylinder, second rectifying cylinder, and first touching lever connects first mechanical valve, and first mechanical valve connects first rectifying cylinder through tracheae; Second touching lever connects second mechanical valve, and second mechanical valve connects second rectifying cylinder through tracheae; Described piston is installed between first rectifying cylinder and second rectifying cylinder, and first mechanical valve and second mechanical valve are communicated with source of the gas respectively.
Further, described correction roller surface is provided with left-hand screw and the right-hand screw that is extended to two ends by the centre.
Further, described cylinder is a balloon-type cylinder.
Further, described mechanical valve is two three-port valves.
Further, described first touching lever and the second touching lever outside are provided with rotating pipe.
Beneficial effect of the present invention is: touching lever does not contact with filter cloth in the normal range (NR) of filter cloth sideslip; When touching lever contacted with filter cloth, the pipe that filter cloth drives on the touching lever rotated, and has reduced the friction between filter cloth and the touching lever to greatest extent, can not produce damage to filter cloth and touching lever substantially; When the filter cloth roller of being rectified a deviation is corrected and to be come and when leaving the mechanical valve touching lever, the cylinder automatic deflation that mechanical valve is communicated with, thus make the correction roller ajust playback automatically; The correction roller is provided with left and right sides spiral, helps the filter cloth correction, and the effect that launches filter cloth is arranged.The present invention makes rectifying deviation of dehydrator filter cloth more safe and reliable.
(4) description of drawings
Fig. 1 is the structural representation of the described device for rectifying deviation of dehydrator filter cloth of invention.
(5) specific embodiment
Below by embodiment the present invention is made preferably specific description, but protection scope of the present invention is not limited to this.
With reference to Fig. 1, a kind of device for rectifying deviation of dehydrator filter cloth, comprise sensing element, rectifying cylinder, correction roller 1, rectifying cylinder is connected with correction roller 1 one ends by piston 2, sensing element is connected with rectifying cylinder through valve, and described sensing element comprises first touching lever 3, second touching lever 4 that is installed in dehydrator filter cloth 11 both sides, and described rectifying cylinder comprises first rectifying cylinder 6, second rectifying cylinder 8, first touching lever 3 connects first mechanical valve, 5, the first mechanical valve 5 and connects first rectifying cylinder 6 through tracheae; Second touching lever 4 connects second mechanical valve, 7, the second mechanical valve 7 and connects second rectifying cylinder 8 through tracheae; Described piston 2 is installed between first rectifying cylinder 6 and second rectifying cylinder 8, and first mechanical valve 5 and second mechanical valve 7 are communicated with source of the gas respectively.
Described correction roller 1 surface is provided with left-hand screw 9 and the right-hand screw 10 that is extended to two ends by the centre.
Described first rectifying cylinder 6 and second rectifying cylinder 8 are balloon-type cylinder.Described first mechanical valve 5, second mechanical valve 7 are two three-port valves.Described first touching lever 3 and second touching lever, 4 outsides are provided with rotating pipe.
When the present invention worked, after filter cloth was run into touching lever, pipe can rotate with the motion of filter cloth, can not produce damage substantially each other.After in first mechanical valve 5, second mechanical valve 7, feeding compressed air, filter cloth is if in the normal range (NR) of sideslip, mechanical valve and cylinder be attonity all, when filter cloth exceeds normal range (NR) and runs into touching lever, the mechanical valve action causes corresponding cylinder charging, thereby (the correction roller is that an end is fixed to promote the action of correction roller, the other end promotes to make its deflection about by piston) have angle with filter cloth, and then make filter cloth run to normal range (NR), mechanical valve is moved once more and is caused the corresponding air bag deflation roller normal position of playbacking of will rectifying a deviation after filter cloth leaves touching lever, and vice versa.Filter cloth can drive the correction roller and rotate when motion, when roller rotated, left and right sides spiral can be to the pulling force of filter cloth generation to both sides, thereby with the filter cloth spread apart, prevent the filter cloth fold, moreover left and right sides spiral strengthens the frictional force between correction roller and the filter cloth, improved the integral error correcting and position effect.After through the break-in of repeatedly rectifying a deviation, filter cloth can be stabilized within its normal range (NR), and the action frequency of mechanical valve reduces, and has prolonged the life-span of correlated parts, and then has reached the purpose that improves host machine integral operational reliability and stability.
