Abstract
The utility model relates to a blast furnace is with one-way from closed adapter sleeve, including borer tail cover (1) and drill rod cover (2), characterized by: a valve sleeve (3) is arranged between the drill rod tail sleeve (1) and the drill rod sleeve (2), a one-way valve (5) is arranged in the valve sleeve, and an air outlet hole (4) is axially formed in the center of the interior of the drill rod sleeve (2). The utility model provides the high life of each accessory of whole tapping hole system has improved work efficiency, has reduced manufacturing cost. The connecting sleeve has strong practicability for opening a blast furnace taphole for iron and steel smelting enterprises.
Description
Technical field
The utility model belongs to the blast furnace open hole drilling tool, connects a kind of adapter sleeve of bit shank and drill steel when being specifically related to blast furnace open hole.
Background technology
At present, the drilling tool adapter sleeve that domestic smelting iron and steel enterprise blast furnace open hole uses all is an ordinary straight jacket casing pipe coupling, but open the influence that is subjected to the effect of axial tension when the back drill steel withdraws from Tie Kou, usually make between drill steel end face and the joint sleeve circular bead surface and produce the gap, cause the blast that is used to cool off to reveal with deslagging, dregs such as molten iron and stemming body refuse are from drill steel head reverse reflux, cause drill steel, adapter sleeve, hit axle, blast mechanical system and whole taphole drilling machine system failure, cause each accessory of tapping outlet system to scrap in advance, the accessory consumption is big, drill steel is scrapped the back and is difficult to unload because of reasons such as high temperature deformations, bring a series of difficult problems to actual production, also increased production cost simultaneously.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art, provides a kind of simple in structure, easy to loading and unloading, blast furnace that can reduce production costs with unidirectional self-enclosed adapter sleeve.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of blast furnace is with unidirectional self-enclosed adapter sleeve, comprise bit shank cover (1) and drill steel cover (2), it is characterized in that: be provided with valve pocket (3) between described bit shank cover (1) and the described drill steel cover (2), be provided with check valve (5) in the valve pocket, drill steel cover (2) inside center is axially arranged with air outlet opening (4).
The outlet of described check valve (5) is connected with air outlet opening (4).
Described bit shank cover (1) body wall is provided with fixedly limiting component.
Described fixedly limiting component is screw rod (6).
The beneficial effects of the utility model are: improved the work-ing life of each accessory of whole tapping outlet system, solved the problem in the actual production, increased work efficiency, reduced production cost.This adapter sleeve is the very strong product of a practicality that is used to open blast furnace taphole at smelting iron and steel enterprise.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1---bit shank cover, 2---drill steel cover, 3---valve pocket, 4---air outlet opening, 5--check valve, 6---screw rod.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Embodiment 1: see Fig. 1, a kind of blast furnace comprises bit shank cover 1 and drill steel cover 2 with unidirectional self-enclosed adapter sleeve, it is characterized in that: be provided with valve pocket 3 between described bit shank cover 1 and the described drill steel cover 2, be provided with check valve 5 in the valve pocket, drill steel overlaps 2 inside center and is axially arranged with air outlet opening 4.
The outlet of described check valve 5 is connected with air outlet opening 4.
Described bit shank overlaps 1 body wall and is provided with fixedly limiting component.
Described fixedly limiting component is a screw rod 6.
During the tapping outlet operation, the high-pressure blast that taphole drilling machine provides is by bit shank, check valve, be transported to drill steel bit location foremost along the drill steel endoporus, the effect that drill bit is played timely cooling and blows dregs such as artillery salvo body refuse.Because check valve is arranged in sleeve pipe, during the tapping outlet operation, check valve can in time form unidirectional self-enclosed, effectively prevents dregs reverse reflux such as molten iron and stemming body refuse and causes the damage of taphole drilling machine air pressure system and whole taphole drilling machine impact system; Fixing spacing screw rod on the bit shank end body body wall plays and prevents to be connected loosening effect with adapter sleeve because of impacting rapping formation bit shank, and is easy to loading and unloading easy to operate.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (4)
1. a blast furnace is with unidirectional self-enclosed adapter sleeve, comprise bit shank cover (1) and drill steel cover (2), it is characterized in that: be provided with valve pocket (3) between described bit shank cover (1) and the described drill steel cover (2), be provided with check valve (5) in the valve pocket, drill steel cover (2) inside center is axially arranged with air outlet opening (4).
2. blast furnace as claimed in claim 1 is characterized in that with unidirectional self-enclosed adapter sleeve the outlet of described check valve (5) is connected with air outlet opening (4).
3. blast furnace as claimed in claim 1 is characterized in that with unidirectional self-enclosed adapter sleeve described bit shank cover (1) body wall is provided with fixedly limiting component.
4. blast furnace as claimed in claim 3 is characterized in that with unidirectional self-enclosed adapter sleeve described fixedly limiting component is screw rod (6).
