The batch offline cleaning and descaling device is characterized by comprising a motor, a pump driven by the motor, and a box body for containing liquid medicine, wherein an inlet of the pump is communicated with the box body, and an outlet of the pump is communicated with a connecting device, the connecting device is provided with a plurality of installation positions and is communicated with the spray rings arranged on the installation positions. when the batch off line cleaning and descaling device is used, the spray rings to be cleaned are soaked in descaling liquid medicine and then are arranged on a link device in the box body after deposition is softened. After the liquid medicine is injected into the spray rings by the pump for washing and descaling the spray rings, the washed liquid medicine passes through a filtering device and directly flows back into the a water box. According to the batch offline cleaning and descaling device provided by the utility model, the operation is simple and convenient, the descaling effect is excellent, a plurality of spray rings are cleaned in batch and the cyclic utilization of the liquid medicine can be realized.
Description
Technical field
The utility model relates to a kind of batch off-line cleaning and descaling device of continuous casting ring sparger, and the off-line that relates in particular to the spray water pipeline inwall incrustation scale of continuous casting two cold section ring sparger cleans.
Background technology
The continuous casting ring sparger is a kind of device to continuous casting two cold section billet surface spray cooling, forms twin nuclei by compressed air pipe and spray header, and the ring inwall has a plurality of nozzles, and ejection water smoke cools off (the ring sparger synoptic diagram is seen Fig. 1) to billet surface.Because the temperature and humidity of ring sparger Working environment of living in alters a great deal, can form incrustation scale at pipe inner wall, and tack is strong, be difficult for cleaning, very easily plug nozzle.
The descaling method that present each iron and steel enterprise generally adopts is: ring sparger is pulled down, carried out heated baking with oxygen-acetylene cutter, impact vibration with hammer again, encrustation is dropped, purge with pressurized air.This method is troublesome poeration not only, and descale effect is bad, can not remove tube wall incrustation fully, can't guarantee that tube wall is smooth, more is prone to fouling once more.
The patent No. is that 99246891.4 Chinese utility model has been described a kind of pig, utilizes the principle of cutter cutting that inner-walls of duct is carried out scale removal, but is not suitable for the pipeline that inner-walls of duct has outstanding device such as nozzle.
Application number is the method that 201010598708.3 Chinese invention patent discloses a kind of water pipe scale removal, and this method uses the mixing solutions of Youxiaolin, sodium-chlor and water as cleaning liquid medicine, injects water pipe to take out stains with certain flow rate.It is the dirt about 1mm that but this method can only be removed thickness, can't remove relatively more obstinate calcified material, and liquid medicine can't reuse.
Summary of the invention
The utility model has designed a kind of batch off-line cleaning and descaling device to the encrustation problem of ring sparger, adopts liquid medicine to soak then and carries out scale removal through the mode of cycle of higher pressure flushing, and effect improves greatly.
The device of the utility model is characterized in that: comprise motor, by motor-driven pump, be used to hold the casing of liquid medicine, the inlet of pump communicates with casing, pump outlet is communicated with a coupling device, this coupling device is communicated with the ring sparger that is mounted thereon.During practical implementation, at first the nozzle of ring sparger and spray piece are removed, are placed scale removal liquid medicine to soak, treat that foulant is softening after, ring sparger is installed on the intravital said coupling device of case with the mode of plug-in mounting washes again.
For realizing cleaning in batches, said coupling device is provided with a plurality of installation positions, six to eight ring spargers generally can be installed clean simultaneously.During cleaning, start motor pump is started working, pump is squeezed into coupling device after the liquid medicine in the casing is extracted out, and liquid medicine sprays from the outlet that encircles inwall after coupling device gets into ring sparger, washes away ring sparger.
For solving contaminant filter problem in the liquid medicine; Box house has been installed a kind of filtration unit, and this filtration unit is lower than ring sparger installation site, the liquid medicine filtration unit of after washing away ring sparger, flowing through earlier; To wash away the contaminant filter that gets off falls just to flow back in the casing; Treat that impurities accumulation arrives when a certain amount of, can pull down filtration unit, dispose the impurity continued and use.Be still solution liquid medicine contaminant filter problem, there is a filtration unit at the water outlet place of casing, and impurities accumulation closes the upper box outlet valve when a certain amount of, can continue after taking filtration unit apart and cleaning out impurity to use.In addition, casing rising pipe position is a little more than bottom half, and some can't will be deposited in bottom half by filtering impurity, before changing liquid medicine or clean casing next time, no longer gets into circulation.
Because the liquid medicine that recycles has corrodibility, so cabinet wall is corrosion-resistant coating, and the pump that is adopted is an acid-resistant ceramic slurry pump, and the motor that is adopted is the mortar pump motor.
In sum, the utlity model has following advantage:
1, the square tube in a plurality of mounting seat hole design can a plurality of ring spargers of disposable batch processing.
2, ring sparger is directly installed on the coupling device in the spray tank, is back in the water tank after liquid medicine cleans to reuse.

Fig. 2 is a ring sparger off-line cleaning device synoptic diagram.
Among the figure, 21, motor, 22, pump, 23, the casing rising pipe, 231, valve, 232, filtration unit, 24, pump outlet, 25, casing, 26, ring sparger, 27, coupling device, 28, liquid medicine.
Embodiment
Combine accompanying drawing that the utility model is described further with embodiment below.
Be illustrated in figure 1 as the synoptic diagram of ring sparger, nozzle 11 can be removed when cleaning with spray piece 12, is installed on the casing coupling device through inlet and installation position 15.
As shown in Figure 2: the utility model system and device by a motor 21, by motor-driven pump 22, the casing 25 that is used to hold liquid medicine forms; The inlet of pump 22 communicates with casing 25; Pump outlet is communicated with a coupling device 27, and this coupling device 27 is communicated with the ring sparger 26 that is mounted thereon.
During use; In casing 25, add liquid medicine 28 earlier, liquid medicine 28 uses AUX's 98 contaminant release agents of dilution, and liquid medicine 28 highly is not higher than coupling device 27; Nozzle on six ring spargers 26 and spray piece are removed the back to be immersed in the liquid medicine 28 24 hours; After treating that foulant is softening, these six ring spargers 26 are installed on the installation position of coupling device 27, mounting means is a plug-in mounting.With pump 22 liquid medicine 28 is squeezed into ring sparger 26; The liquid medicine 28 of ejection washes away ring sparger 26 inwalls; Through directly flowing back in the casing 25 behind the contaminant filter, casing rising pipe 23 is provided with valve 231 and filtration unit 232, impurity filtration unit 232 places be filtered reach a certain amount of after; Valve-off 231 is removed filtration unit 232 impurity is cleared up the continued use.So constantly circulation.The position of rising pipe 23 is slightly higher than the bottom of casing 25, can so that the contamination precipitation that can't be filtered at bottom half.Liquid medicine 28 is if acidic value reduces, and descale effect is not good enough then must be changed.Present embodiment is that six ring spargers are handled simultaneously, and the number of primary treatment ring sparger 26 is by the number of installation position on the volume of casing 25 size, the coupling device 27 and the ability size decision of pump 22.Behind about 4 hours circulation flushing, ring sparger 26 encrustation things clean up inner wall smooth basically.
