Abstract

The utility model relates to a quenching pit flushing device used for a heat treatment device of water quenching of steel pipes, particularly a steel pipe quenching pit iron scale flushing device. The utility model paves by-pass pipes on both sides of the wall of a quenching pit, wherein, the by-pass pipe is provided with a blowhole and is connected with a pipeline spraying water from inside, and the by-pass pipe is also provided with a control valve. The utility model adopts interval water flushing and avoids iron scale because a machine is stopped very often and is washed by manpower, so normal production can be ensured.

Description

Steel pipe quenches and cheats the iron scale flushing arrangement

(1) technical field

The utility model relates to steel pipe shrend thermal treatment unit and cheats flushing arrangement with quenching.

(2) background technology

In technology is quenched in bench type steel pipe rotation spray, below the quenching stand, be provided with the hole of quenching, there is certain obliquity the bottom surface in the hole of quenching, and the Waste Water Centralized after the quench cooled is flowed automatically to Waste Water Treatment to water outlet.Because very big in the moment water yield of quenching, waste water can not in time flow out the hole of quenching, need there be certain degree of depth in the hole of therefore quenching, overflows to prevent waste water.The iron scale that produces when quenching also drops on the bottom, hole of quenching with water coolant, owing to can not flow out the hole of quenching with waste water, iron scale occurs in a large amount of depositional phenomenon in the end, hole.This deposition has reduced the useful volume of quenching and cheating, and causes waste water to overflow the hole of quenching, and influences the surrounding devices works better.And because iron scale quantity is more, therefore often need regularly shut down labor cleaning's iron scale, the influence of wasting time and energy is produced.

(3) summary of the invention

The purpose of this utility model is to provide a kind of steel pipe to quench and cheats the iron scale flushing arrangement, and this hole flushing arrangement that quenches adopts the flushing of compartment water, can avoid often shutting down labor cleaning's iron scale, and assurance is produced and normally carried out.

The utility model is achieved in that a kind of steel pipe quenching hole iron scale flushing arrangement, it is characterized in that being equipped with bypass pipe in the wall both sides, hole of quenching, and spout hole is housed on the bypass pipe.

Above-mentioned steel pipe quenches and cheats the iron scale flushing arrangement, and described bypass pipe connects from interior water pipe, and bypass pipe is provided with variable valve.

The utility model is to establish a bypass pipe in steel pipe on the water pipe, and during interior water spray operation, bypass pipe cuts out; Bypass pipe is opened when stopping to quench, and the hole of quenching is introduced in the water outlet of bypass pipe, flushing hole end iron scale.On bypass pipe, be provided with valve, the size of control bypass pipe washing water quantity and hydraulic pressure, the water yield and hydraulic pressure when it is quenched with interior spray are consistent substantially, the water yield and the water pressure fluctuations impact of main line generation of internally spraying water when avoiding current to switch.This hole flushing arrangement that quenches adopts the flushing of compartment water, can avoid often shutting down labor cleaning's iron scale, guarantees to produce and normally carries out.

(4) description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 cheats iron scale flushing arrangement structural representation for the utility model steel pipe quenches;

Fig. 2 is the schematic top plan view of Fig. 1.

Among the figure: water pipe in 1,2 bypass pipes, 3 quench cheats, 4 spout holes, 5 variable valve, 6 interior water jet standpipe nozzles.

(5) embodiment

Referring to Fig. 1, Fig. 2, a kind of steel pipe quenches and cheats the iron scale flushing arrangement, is equipped with bypass pipe 2 in the 3 wall both sides, hole of quenching, and spout hole 4 is housed on the bypass pipe 2, quenches in order to flushing and cheats the 3 hole iron scale at the end.Bypass pipe 2 connects from interior water pipe 1, and bypass pipe 2 is provided with variable valve 5, with the size of control washing water quantity and hydraulic pressure.When interior water jet standpipe nozzle 6 water sprays quenched operation, variable valve 5 cut out, bypass pipe 2 no water outlets; When stopping the operation of quenching, during interior water jet standpipe nozzle 6 not water outlets, bypass pipe 2 water outlets, hole 3 is washed to quenching.

Claims

1. a steel pipe quenches and cheats the iron scale flushing arrangement, it is characterized in that being equipped with bypass pipe in the wall both sides, hole of quenching, and spout hole is housed on the bypass pipe.

2. steel pipe according to claim 1 quenches and cheats the iron scale flushing arrangement, it is characterized in that bypass pipe connects from interior water pipe, and bypass pipe is provided with variable valve.
