The sweep-out method and the device of cylindrical body for wetting stirrer inwall adhesion layer
The present invention relates to a kind of sweep-out method of cylindrical body for wetting stirrer inwall adhesion layer, particularly relate to the sweep-out method of the strong dust of adhesiveness and the sweep-out method of rotary beating type dust humidifier cylinder inboard wall adhesion layer.In addition, also relate to a kind of device of implementing described removing adsorbed layer from internal surface of cylindrical body method.
Existing various dust humidifier, as the drum-type humidifier, the spiral humidifier of single shaft, twin axle humidifier etc., wherein any, in the dust humidification, the capital forms adhesion layer at cylinder inboard wall, and Chinese utility model patent specification CN2257213Y discloses a kind of improved wetting stirrer, because its rotating speed height, the also corresponding increase of centrifugal force easilier forms solid adhesion layer at cylinder inboard wall.Especially when adding the strong dust of wet adhesion, this problem is more outstanding, and the humidifier performance is reduced, and humidification efficiency descends, and energy consumption increases, humidifying component wearing and tearing aggravation, and make motor overload when serious, see commentaries on classics.In order to address this problem, the method that present various humidifiers are taked is usually for example used ceramic material scraper plate or stirring parts, can only reduce the wearing and tearing of humidifying component; Though the water flushing is feasible, but usually muddy water flows over, form secondary pollution, if following flow device is belt conveyer or other transporter, just do not allow the water flushing, as for adopting method for oscillating to remove adhesion layer, be commonly referred to be impossiblely, for example in the design of jigging conveyer, just think " jigging conveyer generally is not suitable for toughness or granularity is carried less than the 0.06mm powder " (the 160th page of publishing house of construction material Machine Design Wuhan Polytechnical Univ front page in July nineteen ninety).Have close-burning dust in humidifier behind the humidification viscosity stronger, if cylindrical shell is a cylindrical shape,, not only is difficult to be shaken, and might shakes more real and more real because the adhesion layer that inner barrel forms is a cylindrical shape integral body.Therefore, also do not adopt vibrator to solve the dust humidifier of dust bonding so far.Chinese invention patent ublic specification of application CN1048828A discloses and has a kind ofly wiped or the adhesion layer that shakes with floating lever, but only be applicable to the very low occasion of rotating speed of shaft, and the rotating speed of wetting stirrer is higher usually, centrifugal force will make floating lever be pressed on the cylinder inboard wall all the time adhesion layer will be played pressuring action, when cylindrical shell was not garden shape, floating lever was also inapplicable in addition.
The objective of the invention is to provide a kind of sweep-out method of cylindrical body for wetting stirrer inwall adhesion layer, and the device of implementing said removing adsorbed layer from internal surface of cylindrical body method, even being stirred thing by humidification is the strong dust of adhesiveness, also can prevent because the stirring efficiency that adhesion is caused descends, and can reduce or remove the adhesion layer of cylinder inboard wall effectively.
Another object of the present invention is that a kind of device of implementing said removing adsorbed layer from internal surface of cylindrical body method will be provided
The objective of the invention is to realize: or intermittently approximate circle vibration or circular vibration continuous by cylindrical shell with following technical scheme, make the cylindrical shell center line produce relative rotary motion with respect to the shaft center line, its thickness that makes rotating shaft scrape off cylinder inboard wall is equivalent to the adhesion layer of amplitude.
When implementing above-mentioned sweep-out method; bump for fear of cylinder inboard wall and shaft; the peak swing of cylindrical shell is usually less than the radial clearance between cylinder inboard wall and the shaft external diameter; the shaft of rotation can not scrape off the adhesion layer of the thickness of cylinder inboard wall greater than the amplitude part; can keep this part adhesion layer; keep the nonvolatil tack coat of one deck at cylinder inboard wall; the thickness of tack coat is equivalent to peak swing poor of above-mentioned radial clearance and cylindrical shell; before each the shutdown; and when needing in the humidification; produce relative rotary motion by the cylindrical shell center line with respect to the shaft center line; before the new adhesion layer that forms of cylinder inboard wall is strong in time with its removing; between nonvolatil tack coat and shaft external diameter, keep the new soft adhesion layer that forms, both can save energy and also can prevent shaft driving motor stall.In addition, permanent tack coat can also prevent the wearing and tearing and the corrosion of cylinder inboard wall.
Be contained in vibrator on the cylindrical shell and be when in humidification, needing and before each the shutdown and start; stop feedwater before starting; or stop simultaneously feeding water and charging; or the back time-delay of stopping to feed water stops charging, makes to be scraped off or adhesion layer that the moisture content that takes off of shaking is high and dry dust mix from entering to barrel, and moisture content is reduced; the also corresponding reduction of adhesiveness; help removing adhesion layer, also help keeping the soft property of the new adhesion layer that forms, and can save energy water saving.
Another object of the present invention is to realize with following technical scheme: one or more vibrators of installing on the cylinder shell of the wetting stirrer that comprises frame, cylindrical shell, shaft, between cylindrical shell and frame installing isolated supporting device and at vibrating mass and the installing of the junction between vibrating mass flexible sealing arrangement not, this is a kind of simple and easy to do device of the said removing adsorbed layer from internal surface of cylindrical body method of enforcement.The shaft of wetting stirrer can be one, also can be more than one.Vibrator can be contained in the top of cylindrical shell, also can be contained in the cylindrical shell side, can adorn one and also can adorn two, can certainly adorn more than two.But adorn one simple in structure and can make cylindrical shell produce the approximate circle vibration.Install two vibrators and then can realize circular vibration.This structure also is convenient to existing various dust humidifiers are undergone technological transformation.For satisfying the requirement of cylindrical shell amplitude, cylindrical shell 3 or mixing drum 3a are bearing on the frame 8 with isolated supporting device 12.The isolated supporting device guarantees that cylindrical shell 3 or mixing drum 3a have bigger amplitude, but the amplitude of complete machine is then less.The oscillating component of cylindrical shell and other do not need certain clearance between the vibrating mass, dust just may be overflowed from this gap, at vibrating mass and do not install flexible sealing arrangement between the vibrating mass, flexible sealing arrangement can prevent that dust from escaping for this reason, and does not influence the cylindrical shell vibration.Flexible sealing arrangement comprises flexible seal circle and clip, and the flexible seal circle can use materials such as TR thin rubber, polyester canvas, asbestos canvas, artificial leather to make, and preferably makes bellow-shaped.
If whole cylindrical shell all vibrates, flexible sealing arrangement should be located between the batcher of rotary beating type dust humidifier and charging aperture top, for the interior pipe 16 of this charging aperture 4 stretches in the feed pipe 14, seal with flexible seal circle 17 between the outer tube 15 of charging aperture 4 and the feed pipe 14, one end of flexible seal circle 17 is fixed on the charging aperture outer tube 15 with clip 18, and the other end is fixed on the feed pipe 14 with clip.Pipe 16 and the gap of outer tube 15 between feed pipe should guarantee neither can collide with interior pipe 16 when feed pipe 14 vibrates with cylindrical shell 3 in the charging aperture, also can not collide with outer tube 15.
If the shell portion ginseng is shaken, then separately becoming two parts for barrel 3b and mixing drum 3a, be fixed on the frame 8 for barrel 3b, and stretch in the mixing drum 3a, mixing drum 3a is bearing on the frame 8 with isolated supporting device 12, between the two with 11 sealings of flexible seal circle, one end of flexible seal circle 11 is fixed on the mixing drum 3a with clip 13, the other end is fixed on the flange 20 to barrel 3b with clip 13, because charging aperture is not joined and is shaken, therefore, can not install flexible sealing arrangement between charging aperture top and the batcher.This structure also is specially adapted to existing dust humidifier is undergone technological transformation.
In order to make the relative rotary motion of cylindrical shell center line generation with respect to the shaft center line, bearing block should be contained on the frame, should there be enough big gap at the position that shaft passes the end cap 23 of cylindrical shell 3, install following flexible seal structure in case of necessity: on the end cap 23 of cylindrical shell 3 flange 24 is housed, seal with flexible seal circle 26 between flange 24 and the lid 25, one end of flexible seal circle 26 is fixed on the flange 24 with clip 27, the other end is fixed on the lid 25 with clip 27, between lid 25 and the shaft 5 sealing ring 28 is housed.
Cylindrical shell 3 is tiltedly installed with and is beneficial to quickening and is stirred beyond the region of objective existence row by humidification, especially can accelerate to be effluxed by the vibrator adhesion layer that falls that shakes.Similar to jigging conveyer, vibrator tilts to install also can be accelerated to be stirred beyond the region of objective existence row by humidification.
In humidification mix process, when cylinder inboard wall adhesion layer when thickening firms gradually, stir resistance and increase, the also corresponding increase of the electric current of shaft driving motor just starts vibrator, the cylinder inboard wall adhesion layer become solid before in time with its removing; After the adhesion layer of cylinder inboard wall was shaken and takes off, it is normal that the electric current of shaft driving motor recovers, and just closes vibrator; Therefore vibrator is to start or stop with electric current relay or current sensor 22 size of current according to the shaft drive motor.The batcher of the magnetic valve of control water and control charging and vibrator interlock.Certainly, also can rule of thumb or by the size of current of ammeter observation shaft driving motor operate by artificial.Can certainly when starting vibrator, stop feed and continue feedwater, utilize vibration and water to clean barrel, but usually muddy water flow over, form secondary pollution, should not adopt.
The control vibrator starts or the electric current relay or the current sensor 22 of cutting out usefulness is connected on the power line of shaft drive motor 21, be used to start or close the A.C. contactor of vibrator and the normal opened contact of electric current relay or current sensor 22 links, when the electric current of shaft drive motor 21 surpasses setting value, electric current relay or current sensor 22 actions, the normal opened contact closure, be used to start or close the A.C. contactor action of vibrator, vibrator starts, otherwise, the vibrator closure.
Though increased energy consumption after adding vibrator, because the frictional resistance of stirring parts and cylinder inboard wall adhesion layer reduces, total is still energy-conservation.Several dust humidifiers that production capacity is similar in production practices, wherein the power of a dust humidifier is 11KW, and stall often takes place, and changes 22KW into and just deals with problems; The power of an external dust humidifier of introducing is 18KW; Another dust humidifier is when the stronger dust of humidification caking property, and power is 7.5KW, because the vibrating motor of a 0.75KW of installing works well, stall does not take place.
The as above detailed description of being done, the sweep-out method and the device of cylindrical body for wetting stirrer inwall adhesion layer of the present invention can scrape off the adhesion layer of cylinder inboard wall, therefore effectively, even the adhesiveness of handled dust is strong, can prevent that also the whipping performance that the cylinder inboard wall adhesion layer is caused from descending.Since be just to form at adhesion layer but before strong as yet it is not shaken, so energy consumption is low, effective.And be to take the mode that stops to spray water when starting vibrator, make to be scraped or the high adhesion layer of moisture content that falls that shakes mixes with the dry dust that enters from charging aperture, its humidity is reduced, adhesiveness and stir resistance also along with reducing and being easy to discharge from discharging opening.Therefore, when reducing and removing adhesion layer, can economize on water, energy-conservation.
