An object of the utility model is to provide a dry coke quenching boiler feed pump filter, this filter effect is good, and can online cleaning, reduces the pressure fluctuation of the main pipe of feedwater, guarantees production safety.
The technical scheme of the utility model is that: a water-feeding pump filter of a coke dry quenching boiler is arranged on a cooling water-feeding pipeline of the coke dry quenching boiler and comprises two filtering high barrels, a base, a water inlet pipe three-way valve and a water outlet pipe three-way valve,
the base is two parallel side frames which are arranged at two sides of the cooling water pipeline, and the high filtering barrel is arranged at the upper part of the base;
the top of the high filtering barrel is provided with a sealing cover, the upper part of the side wall is provided with a water inlet pipe, the lower part is provided with a water outlet pipe, a filter screen barrel is arranged in the high filtering barrel,
the water inlet pipe three-way valve is arranged between the two high filtering barrels, is connected with the water inlet pipe and the cooling water pipeline of the two high filtering barrels and is used for controlling the cooling water in the cooling water pipeline to enter the high filtering barrels,
the outlet pipe three-way valve is arranged between the two filtering high barrels, connects the outlet pipes and the cooling water pipeline of the two filtering high barrels, and is used for controlling the cooling water filtered by the filtering high barrels to flow out to the cooling water pipeline.
The filtering high barrel is a barrel, the height of the filtering high barrel is 40-60 cm, and the diameter of the filtering high barrel is 15-25 cm.
The upper part of the filter screen barrel is fixedly connected with a handle.
The filter screen bucket wall is gone up the equipartition and is had a plurality of filtration pores, and the filter screen bucket top is provided with the horn mouth, and the horn mouth matches with filtration height bucket internal diameter, and the horn mouth is located filtration height bucket water inlet downside.
The top end of the high filtering barrel is provided with a fixed flange, and the sealing cover is fixedly connected with the flange plate.
The utility model discloses simple structure, the filter effect is good, can effectively reduce the low warning of the cooling water pressure of putting out coke boiler system futilely, guarantees system production safety.

Detailed Description
As shown in figures 1 and 2, a water feeding pump filter of a coke dry quenching boiler is arranged on a cooling water feeding pipeline of the coke dry quenching boiler and comprises two filtering high barrels 1, a base 2, a water inlet pipe three-way valve 3 and a water outlet pipe three-way valve 4,
the base 2 is two supports which are arranged in parallel, arranged on two sides of the cooling water pipeline 10 and fixed on the ground, and the high filtering barrel 1 is fixedly arranged on the upper part of the base 2, wherein the high filtering barrel is a barrel, the height of the high filtering barrel is 50cm, the diameter of the high filtering barrel is 20cm, and the filtering efficiency can be improved;
the top of the high filtering barrel 1 is provided with a sealing cover 11, the top end of the high filtering barrel is provided with a fixing flange, the sealing cover 11 is fixedly and hermetically connected with a flange plate, the upper part of the side wall is provided with a water inlet pipe 12, the lower part of the side wall is provided with a water outlet pipe 13, a filter screen barrel 14 is arranged in the high filtering barrel, the upper part of the filter screen barrel is fixedly connected with a handle 141, the filter screen barrel is convenient to take out or put into when the filter screen barrel is replaced, the top end of the filter screen barrel 14 is provided with a horn mouth 142, the horn mouth 142 is matched with the inner diameter of the high filtering barrel, and the horn mouth is positioned at the lower side of a water inlet;
the water inlet pipe three-way valve 3 is arranged between the two filtering high barrels, is connected with the water inlet pipes 12 of the two filtering high barrels and the cooling water pipeline 10 and is used for controlling cooling water in the cooling water pipeline to enter the filtering high barrels, and the filtering high barrels into which the cooling water enters can be adjusted by switching the water inlet pipe three-way valve;
