Description
Technical Field
The utility model relates to the technical field of metallurgy, in particular to a cleaning device for a secondary cooling spray rack of a slab caster sector section.
Background
Along with the development of industry, the requirements on the quality of casting blanks are more strict, the company strives to develop variety steel, secondary cooling of the casting blanks in the production process of a slab caster is a direct influence point on the quality of the casting blanks, and if local nozzles of a secondary cooling spraying system are blocked in the production process, the cooling balance of a secondary cooling area of the casting blanks is changed, so that the casting blanks are cooled unevenly, and the quality problems of corner cracks, center line cracks and the like of the casting blanks are caused; at present, the cleaning mode of the secondary cooling water nozzle is to carry out inspection and cleaning for on-line regular maintenance, but the sector section to which the secondary cooling nozzle of the continuous casting machine belongs is mainly prepared and works under the on-line state, so that the sector section needs to carry out good cleaning work of the secondary cooling water system before the sector section is on the on-line state; along with the increase of slab caster live time, fan-shaped section secondary cooling water frame inside can accumulate impurity such as certain dirt piece, fatlute and attach to on pipeline wall and the nozzle shower inner wall, but lean on general washing to hardly reach the wooden point of effective clearance, along with fan-shaped section online use, in case debris drop can cause the nozzle to block up, influence casting blank secondary cooling's quality.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems, and provides a cleaning device for a secondary cooling spray rack of a slab caster fan-shaped section, which adopts a circulating cleaning method, wherein a medicament is chemically reacted with impurities in the spray rack, a nozzle and a spray pipe and then discharged into a liquid storage tank along with the medicament, so that the cleaning effect and the cleaning efficiency are improved.
The utility model solves the problems and adopts the technical scheme that:
the utility model provides a belt cleaning device that is used for aftercooling of slab caster fan-shaped section to spray frame, is provided with water inlet and delivery port respectively including the medicament of washing usefulness, spray the frame and set up nozzle and the shower on spraying the frame, the water inlet has connected gradually circulating pump and liquid storage tank through the pipeline, and the medicament setting is in the liquid storage tank, and the delivery port passes through the pipeline and is connected with the liquid storage tank.
Compared with the prior art, the utility model adopting the technical scheme has the outstanding characteristics that:
the utility model adopts a circulating cleaning method, and the medicament is chemically reacted with the impurities in the spray frame, the spray nozzle and the spray pipe and then discharged into the liquid storage tank along with the medicament, so that the cleaning effect and the cleaning efficiency are improved.
Preferably, the further technical scheme of the utility model is as follows:
the spraying frame is also provided with an air inlet and an air outlet, the air inlet and the air outlet are respectively provided with a valve, and the air inlet is connected with an air source outlet through a pipeline; can be with spraying the inside weathering of a pipe wall through input gas, can clear up the inside residue of a pipe wall of spraying simultaneously.
Drawings
FIG. 1 is a schematic view of a mounting structure of an embodiment of the present invention;
in the figure: a spray frame 1; a water inlet 11; a water outlet 12; an air inlet 13; an air outlet 14; a circulating pump 2; a liquid storage tank 3; and a gas source outlet 4.
Detailed Description
The utility model will be better understood by the following description of embodiments thereof, but the applicant's specific embodiments are not intended to limit the utility model to the particular embodiments shown, and any changes in the definition of parts or features and/or in the overall structure, not essential changes, are intended to define the scope of the utility model.
Referring to fig. 1, the technical scheme of the utility model is as follows:
a cleaning device for a secondary cooling spray rack of a fan-shaped section of a slab caster comprises a medicament for cleaning, the spray rack 1, and a nozzle and a spray pipe which are arranged on the spray rack 1, wherein the spray rack 1 is respectively provided with a water inlet 11 and a water outlet 12, the water inlet 11 and the water outlet 12 are respectively provided with a valve, the water inlet 11 is sequentially connected with a circulating pump 2 and a liquid storage tank 3 through pipelines, the medicament is arranged in the liquid storage tank 3, and the water outlet 12 is connected with the liquid storage tank 3 through a pipeline; the medicament comprises: hydrochloric acid for cleaning scale, oil removing agent or strong base for cleaning oil sludge; compared with a cleaning method adopting a medicine pool for soaking, the cleaning method adopting the circulating cleaning method improves the cleaning effect of the spray frame 1, shortens the cleaning period, optimizes the cleaning period from 3 days/station to 1 day/station, improves the cleaning frequency of the nozzles and the spray pipes from the original manual single cleaning to 10 cleaning frequencies, and improves the cleaning work efficiency.
The spray rack 1 is also provided with an air inlet 13 and an air outlet 14, the air inlet 13 and the air outlet 14 are respectively provided with a valve, and the air inlet 13 is connected with an air source outlet 4 through a pipeline; the interior of the pipe wall of the spray rack 1 can be dried by inputting gas, and meanwhile, residues in the pipe wall of the spray rack 1 can be cleaned; the gas source adopts nitrogen or argon.
The working principle of the device is as follows: add required medicament at first in liquid storage tank 3, then be connected the pipeline on the delivery port of liquid storage tank 3 with water inlet 11 on the spray rack 1, start circulating pump 2 after the installation and make the medicament input to spray rack 1 in, clear up nozzle and shower on the spray rack 1 simultaneously, medicament after the clearance and the impurity of mixing in the medicament flow back and continue to circulate in liquid storage tank 3.
Compared with the cleaning method adopting the medicine pool for soaking, the cleaning method adopts a circulating cleaning method, the medicine is chemically reacted with the impurities in the spray frame 1, the spray nozzles and the spray pipes and then is discharged into the liquid storage tank 3 along with the medicine, so that the cleaning effect and the cleaning efficiency are improved, and compared with the cleaning method adopting the medicine pool for soaking, the outer walls of the spray frame 1, the spray nozzles and the spray pipes are not in direct contact with the medicine, so that the corrosion damage in the cleaning process can be avoided, and the service life of the cleaning method is prolonged.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, which is defined in the appended claims.
