Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to an oil casing quenching outer shower water spraying device belongs to metallurgical industry mechanical equipment technical field. BACKGROUND
[0002] Steel pipe heat treatment is mainly through heating, heat preservation and cooling process to improve the key production line of steel pipe performance, mainly involves products have oil casing, high pot pipe, structure pipe, fluid pipe etc., steel pipe heating to a certain temperature needs to be cooled quickly the process is quenching, quenching device outer shower equipment is the key equipment of quenching, and the outer shower water spraying needs to be uniform, and the water supply pressure is stable and reliable, can effectively guarantee the straightness of steel pipe quenching.
[0003] At present, the heat treatment quenching device adopts the form of water tank waterway elbow pipe water spraying, as shown in the figure, the design defects have the following problems: Figure 1
[0004] 1, adopt the water tank serpentine elbow pipe form, carbon steel material, small caliber, elbow pipe length reaches 2 meters above, uses nearly 12 years, rust and scale is serious, cleaning is difficult, causes the non-uniformity of steel pipe cooling, influences the uniformity of steel pipe performance.
[0005] 2, the length of elbow pipe is long, and the water resistance is big, which influences the spraying pressure and the hardenability. SUMMARY
[0006] The utility model provides an oil casing quenching outer shower water spraying device aiming at the prior art, which has simple structure, is convenient for cleaning the sundries in the water tank, improves the water supply pressure of the outer shower, improves the uniformity of the outer spraying water, and guarantees the uniformity of the steel pipe quenching.
[0007] The utility model adopts the technical scheme that the above problems are solved: an oil casing quenching outer shower water spraying device, including the water tank, the water tank is connected with the water supply pipe, the water tank lower portion is equipped with the nozzle unit, and the nozzle unit is in screw thread connection with the water tank.
[0008] The nozzle unit includes a plurality of evenly spaced nozzles, and the top end of the nozzle exceeds the inner wall of the bottom of the water tank by 5-10 mm.
[0009] The repair opening is provided with a plurality of repair openings.
[0010] The water tank and the nozzle are made of stainless steel material.
[0011] Compared with the prior art, the advantages of this utility model are as follows: An external water spray device for quenching oil casing has a straight-through threaded connection between the nozzle and the water tank, resulting in a simple structure, convenient installation, reduced water resistance, and increased external water supply pressure. Opening the inspection port facilitates regular cleaning of debris inside the water tank, reducing nozzle clogging and ensuring stable quenching uniformity. Attached Figure Description
