Description

Cooler pipeline online cleaning device

Technical Field

The utility model relates to a cooler overhauls equipment technical field, concretely relates to cooler pipeline on-line cleaning device.

Background

A frequency converter which drives a main exhaust fan to operate in a sintering plant generally carries out cooling through an internal circulating water cooler; the flow path of the internal circulation water of the cooler is as follows: water in the main water inlet pipe sequentially passes through the water inlet main stop valve and the water inlet pipeline, is introduced into the cooler pipeline from the inlet of the cooler pipeline, and then sequentially flows back to the main water return pipe from the outlet of the cooler pipeline through the water return pipeline and the water return main stop valve. After the cooler is used for a period of time, scales can be formed in the cooler pipeline, so that the cooling effect of the cooler is poor; at present, the cooling effect is recovered by a method of overhauling and replacing a cooler pipeline assembly or replacing the whole cooler, but the overhauling and replacing the cooler pipeline assembly wastes time and labor, and the use cost of an enterprise is greatly increased by replacing the whole cooler. Therefore, the invention is needed to invent a cooler maintenance device which is time-saving, labor-saving and low in enterprise use cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a labour saving and time saving and the online belt cleaning device of cooler pipeline that use cost is low of enterprise.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the online cleaning device for the cooler pipeline comprises a cleaning water tank, wherein a partition plate is arranged inside the cleaning water tank, an overflow gap is reserved between the top of the partition plate and a top plate of the cleaning water tank, the partition plate divides the inside of the cleaning water tank into a water outlet cavity and a water return cavity which are communicated through the overflow gap, a submersible pump is arranged at the lower part of the water outlet cavity, a water outlet pipe communicated with an outlet of the submersible pump is arranged outside the water outlet cavity, and a water outlet valve for opening and closing the water outlet pipe is arranged on the water outlet pipe; a water return pipe communicated with the water return cavity is arranged outside the water return cavity, a water return valve for opening and closing the water return pipe is arranged on the water return pipe, a sewage discharge outlet is arranged at the bottom of the water return cavity, and a sewage discharge valve is arranged at the sewage discharge outlet.

Further, the online cleaning device for the cooler pipeline comprises: a vertical pipe is arranged in the water return cavity, the lower end of the vertical pipe extends downwards to the middle part of the water return cavity, and the upper end of the vertical pipe is communicated with the water return pipe.

Further, the online cleaning device for the cooler pipeline comprises: a filter screen is arranged at the overflow gap.

Through the implementation of the above technical scheme, the beneficial effects of the utility model are that: simple structure, convenient operation can resume the cooling effect of cooler through carrying out online cleaning to the cooler pipeline, and labour saving and time saving, low in cost, greatly reduced the use cost of enterprise.

Drawings

Fig. 1 is a schematic view of the working principle of the on-line cleaning device for cooler pipes according to the present invention.

Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

As shown in fig. 1, the online cleaning device for the cooler pipeline comprises a cleaning water tank 1, wherein a partition plate 2 is arranged inside the cleaning water tank 1, an overflow gap is reserved between the top of the partition plate 2 and a top plate of the cleaning water tank 1, the partition plate 2 partitions the inside of the cleaning water tank 1 into a water outlet chamber 3 and a water return chamber 4 which are communicated through the overflow gap, a submersible pump 5 is arranged at the lower part of the water outlet chamber 3, a water outlet pipe 6 communicated with an outlet of the submersible pump 5 is arranged outside the water outlet chamber 3, and a water outlet valve 7 for opening and closing the water outlet pipe 6 is arranged on the water outlet pipe 6; a water return pipe 8 communicated with the water return cavity 4 is arranged outside the water return cavity 4, a water return valve 9 for opening and closing the water return pipe 8 is arranged on the water return pipe 8, a sewage discharge port 10 is arranged at the bottom of the water return cavity 4, and a sewage discharge valve 11 is arranged at the sewage discharge port 10; in the embodiment, a vertical pipe 12 is arranged in the backwater chamber 4, the lower end of the vertical pipe 12 extends downwards to the middle of the backwater chamber 4, the upper end of the vertical pipe 12 is communicated with the backwater pipe 8, the sewage backflow direction in the cleaning process can be controlled to the bottom of the backwater chamber through the vertical pipe, larger particles of scale can be controlled to deposit at the bottom of the backwater area, and the probability of scale suspension is reduced; in the embodiment, the filter screen 13 is arranged at the overflow gap, so that suspended matters and scales in the water return chamber can be effectively prevented from entering the water outlet chamber through the filter screen, and the cleaning effect is improved;

when the cooler is cleaned on line, the water outlet pipe 6 is connected with a water inlet pipeline 16 between a water inlet main stop valve 15 and the inlet of the cooler pipeline 141, and the water return pipe 8 is connected with a water return pipeline 18 between a water return main stop valve 17 and the outlet of the cooler pipeline 141; then closing the water inlet main stop valve 15 and the water return main stop valve 17, opening the water outlet valve 7 and the water return valve 9, and starting the submersible pump 5, at this time, the submersible pump 5 will introduce the cleaning water in the water outlet chamber 3 in the cleaning water tank 1 into the cooler pipeline 141 through the water outlet pipe 6, the water outlet valve 7 and the water inlet pipeline 16, in the process that the cleaning water passes through the cooler pipeline 141, the cleaning water will flush the inside of the cooler pipeline 141, and bring the scales in the cooler pipeline 141 out of the cooler pipeline 141, the cleaning water mixed with the scales flows back to the water return chamber 4 of the cleaning water tank 1 through the water return pipeline 18, the water return valve 9, the water return pipe 8 and the vertical pipe 12, after the cleaning water mixed with the scales enters the water return chamber 4, the scales will sink to the bottom of the water return chamber 4, and the upper cleaning water will overflow from the filter screen 13 to the water outlet chamber 3 for recycling, through the filtration of the filter screen 13, large-particle suspended matters can be retained in the water return chamber 4 and cannot flow back into the pipeline of the cooler again, so that the cleaning effect is ensured; after the cooler pipeline is cleaned, the drain valve 11 is opened to discharge the sewage and the scale in the water return chamber 4.

The utility model has the advantages that: simple structure, convenient operation can resume the cooling effect of cooler through carrying out online cleaning to the cooler pipeline, and labour saving and time saving, low in cost, greatly reduced the use cost of enterprise.
