Sequential spraying guide pipe at inlet of large rod line cooler

Abstract

The utility model relates to the technical field of bar rolling production, in particular to a forward spraying guide pipe at an inlet of a large bar line cooler, and aims to solve the problem that the head of a bar is easy to collide with the forward spraying guide pipe due to the structural design defect of the forward spraying guide pipe of the cooler in the bar rolling and cooling process at present. And the cooler is finally damaged and scrapped, so that the purchase cost of spare parts of the large rod wire is greatly increased. The nozzle extends and lengthens the inlet conduit of the cooler, so that the impact force of the head of a bar is effectively and completely released to the horn mouth of the conduit, and the service life of the cooler can be effectively prolonged only by regularly replacing spare parts of the inlet conduit; the inlet assembly of the cooler is designed in a split mode, spare parts of the inlet guide pipe, the forward spraying guide pipe and the cooling guide pipe can be rapidly and conveniently replaced in a pipe cavity through bolts, the frequency that the head of a bar collides with the forward spraying guide pipe is effectively reduced, and production accidents caused by fragmentation of the forward spraying guide pipe and the phenomenon that the whole cooler is scrapped and damaged are completely eradicated.

Description

Technical Field

[0001] The utility model relates to the technical field of bar rolling production, in particular to a longitudinal spraying conduit at an inlet of a large bar wire cooler. Background Art

[0002] At present, the domestic demand for rebar production of steel rolling production lines, especially the rapid development of rolling line capacity improvement, has made it an inevitable trend to improve the capacity of rolling lines. By transforming the inlet duct of the cooler, it can play a vital role in the production line capacity. The existing coolers used on site need to be regularly offline for maintenance of cooler spare parts and replace the cooling duct, reverse spray duct, blowing duct, downstream spray duct and inlet duct during use. During each replacement process, the cooler works in a hot and humid environment for a long time, resulting in the inability to remove the downstream spray duct bushing and spare parts. Only other spare parts can be replaced, resulting in the inability to replace the downstream spray duct for a long time. Service online, when the steel pile head enters the cooler, the head hits the downstream spray duct, resulting in the downstream spray duct being broken and the frequency of steel pile increasing. In order to avoid the occurrence of production accidents during steel pile maintenance, the principle of overall scrapping of the cold zone device can only be adopted, which greatly increases the purchase cost of spare parts for large bar wire coolers. Utility Model Content

[0003] The utility model provides a large rod wire cooler inlet forward spray conduit to solve the problems existing in the above background.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A large rod wire cooler inlet downstream duct comprises a first cavity, an extended inlet duct is penetrated through the inner side of the first cavity, the extended inlet duct is connected with a downstream duct, the downstream duct is connected with an inlet assembly cavity, and the inlet assembly cavity is connected with a cooling duct.

[0006] Furthermore, a second cavity is provided on the outer side of the downstream injection duct, and the second cavity and the inlet assembly cavity are detachably connected via cavity connecting bolts.

[0007] Furthermore, one side of the cooling conduit is also connected with a nozzle.

[0008] The utility model has the following beneficial effects:

[0009] The utility model provides an inlet downstream duct of a large rod and wire cooler, which is mainly composed of components such as an extended inlet duct, a downstream duct, a cooling duct, a cavity and a nozzle. By extending and lengthening the inlet duct of the cooler, the impact force of the rod head is effectively released to the bell mouth of the inlet duct, and the service life of the cooler can be effectively extended by regularly replacing the inlet duct spare parts. The inlet of the cooler is designed as a whole, and the inlet duct, the downstream duct and the cooling duct can be quickly and conveniently replaced by dismantling the bolts in the tube cavity, which effectively reduces the frequency of the rod head hitting the downstream duct, eliminates production accidents caused by the breakage of the downstream duct and the overall scrapping and damage of the cooler, greatly reduces the procurement cost of spare parts for large rods and wires, and solves the problem that in the current process of rolling and cooling of rods, the rod head is usually very easy to hit the downstream duct due to the structural design defects of the cooler downstream duct, causing the downstream duct to be broken and eventually causing damage and scrapping of the cooler, thereby greatly increasing the procurement cost of spare parts for large rods and wires.

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] like Figure 1 As shown, an inlet downstream duct of a large rod wire cooler comprises a first cavity 6, an extended inlet duct 1 is penetrated through the inner side of the first cavity 1, the extended inlet duct 1 is connected to the downstream duct 2, the downstream duct 2 is connected to the inlet assembly cavity 5, and the inlet assembly cavity 5 is connected to the cooling duct 3.

[0015] A second cavity 7 is provided on the outer side of the downstream duct 2 , and the second cavity 7 and the inlet assembly cavity 5 are detachably connected via cavity connecting bolts 4 .

[0016] One side of the cooling conduit 3 is also connected to a nozzle 8 .

[0017] When the utility model is used in a specific application, the cooler inlet downstream jet duct is processed and manufactured in sequence according to the diagram, and after checking whether the dimensions of each part are qualified, it is installed at the inlet of the large rod and wire cooler. By extending and lengthening the cooler inlet duct, the impact force of the rod head is effectively released to the duct bell mouth, and the service life of the cooler can be effectively extended by only regularly replacing the spare part of the extended inlet duct 1. The cooler inlet is designed as a whole, and the extended inlet duct 1, the downstream jet duct 2 and the cooling duct 3 can be quickly and conveniently replaced as spare parts in the second cavity 7 through the cavity connecting bolts 4, which effectively reduces the frequency of the rod head hitting the downstream jet duct 2, and prevents production accidents caused by the breakage of the downstream jet duct 2 and the overall scrapping and damage of the cooler. Therefore, the duct has good practicality.
