Abstract
The utility model discloses a blast furnace taphole grouting pressure head, which comprises a main body and a grouting bent tube and is disposed at one end of a blast-furnace gun head. The main body comprises a front drum section and a rear drum section with different diameters, the rear drum section extends into the gun head to be fixed, a grouting through hole is radially arranged on the front drum section, and the grouting bent tube is disposed on the side wall of the front drum section and communicated with the grouting through hole. The grouting pressure head can be stably fixed on the surface of a taphole mud liner by aid of the blast-furnace gun head and is sealed with the mud linear surface, and slurry is pressed into a taphole channel through the grouting bent tube and the front drum section, so that mud-jacking at clearances on the periphery of the blast furnace taphole can be implemented and maintenance and temperature reduction at an inner lining on the side wall of a hearth on the periphery of the taphole are realized.
Description
Technical field
The utility model relates to the blast furnace squeezing unit, more particularly, relates to a kind of blast furnace taphole grouting pressure head.
Background technology
Blast furnace is the important place that iron and steel enterprise produces molten iron.In a generation in furnace life; especially in the stove labour later stage; the situation of blast furnace hearth refractory materials (mainly being meant the erosion condition of the anti-material of cupola well inner side-wall) is directly connected to the longevity of blast furnace; cupola well inner side-wall protection slag crust must be in certain residual thick scope to furnace shell; blast furnace just can safety production; otherwise if the residual thick safety control line that is lower than just has the danger that cupola well is burnt.Therefore must take to improve cooling intensity, reduce combustion intensity (comprising the underproduction, interim damping down, stifled air port) and add measure such as titanium ore furnace retaining.In addition, be exactly at the high possible cause of side wall temperatures in addition, mud jacking is carried out in slit between the anti-material of cupola well sidewall and water cooler, the furnace shell, fill air gap in the anti-material by mud jacking with slurry, thereby reduce the temperature of anti-material.At present, generally there is cover in grout hole on cupola well, the iron mouth cooling stave, the air port common mud jacking position, cover and air port are inferior greatly, but, because iron mouth place exists bore big, environment is poor, can't effectively seal, and very difficult fixed problem, therefore up to the present, be difficult to again iron mouth place and carry out mud jacking preferably, cause blast furnace taphole around the cupola well sidewall can't effectively be lowered the temperature and be repaired all the time.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of blast furnace taphole grouting pressure head, and this grouting pressure head can be implemented in Tie Kouchu and carry out mud jacking.
For achieving the above object, the utility model adopts following technical scheme:
This blast furnace taphole grouting pressure head is located at the first end of blast furnace gun big gun, comprise body and grouting bend pipe, body is designed to former and later two waney drum sections, back one drum section stretches in the clay gun big gun head and fixes, last drum section radially have one grouting through hole, the grouting bend pipe is located on the sidewall of last drum section, and is connected with the grouting through hole.
Also have the annular recesses of two embedded packing_seals on the front end face of described last drum section.
Described grouting bend pipe is provided with ball valve.
The external diameter and the clay gun big gun head internal diameter of described back one drum section are complementary; The external diameter of described last drum section is greater than the external diameter of back one drum section.
Described body, grouting bend pipe and ball valve all adopt high temperature resistant, high voltage bearing steel material.
In technique scheme, blast furnace taphole grouting pressure head of the present utility model is located at the first end of blast furnace gun big gun, comprise body and grouting bend pipe, body is designed to former and later two waney drum sections, back one drum section stretches in the clay gun big gun head and fixes, last drum section radially have one grouting through hole, grouting bend pipe be located on the sidewall of last drum section, and with grouting through hole be connected.This grouting pressure head utilizes blast furnace gun big gun head self to be stabilized on the iron mouth mud cover face, and with the face seal of mud cover, by grouting bend pipe and last drum section, slurry is pressed in the iron mouth pore passage, thereby can carry out effective mud jacking to slit around the blast furnace taphole, realize iron the mouth rebuild maintenance and the cooling of cupola well sidewall liner on every side.
Description of drawings
Fig. 1 is the working state schematic representation of blast furnace taphole grouting pressure head of the present utility model;
Fig. 2 is the structural representation of grouting pressure head of the present utility model;
Fig. 3 is the structure cross-sectional schematic of grouting pressure head of the present utility model.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 1～shown in Figure 3, blast furnace taphole grouting pressure head 10 of the present utility model is located at blast furnace gun big gun head 1 front end, is used for the mud jacking to blast furnace taphole 2 positions.This grouting pressure head 10 comprises body 11 and grouting bend pipe 12, and body 11 is designed to former and later two waney drum sections, and the external diameter and clay gun big gun head 1 internal diameter of back one drum section 111 are complementary, and stretches in the clay gun big gun head 1 also fixing; The external diameter of last drum section 112 greater than the back one drum section 111 external diameter, and last drum section 112 radially have one grouting through hole 113, grouting through hole 113 be connected with the endoporus of last drum section 112; Grouting bend pipe 12 is located on the sidewall of last drum section 112, and is connected with grouting through hole 113, and grouting also is provided with ball valve 121 on the bend pipe 12, by ball valve 121 grouting bend pipe 12 is linked to each other with grouting hose on the grout machine, and can control filling process.On the front end face of last drum section 112, also have the annular recesses 114 of two embedded packing_seals, be used for the sealing between this grouting pressure head 10 and the iron mouth 2.In addition, the body 11 of this grouting pressure head 10, grouting bend pipe 12 and ball valve 121 all adopt high temperature resistant, high voltage bearing steel material, are suitable for operation under near the hot environment the blast furnace taphole 2.
The former road of the work of this grouting pressure head 10 is as follows: be fixed on the clay gun big gun head 1 by back one drum section 111 pressure head 10 that will be in the milk earlier, this moment, ball valve 121 was a closing condition, utilize the taphole drilling machine drill bit that iron mouth 2 is carried out perforate then, after being drilled into certain depth, cleaned iron mouth mud cover face 3, made smooth, the cleaning of its maintenance; And then the clay gun big gun head 1 that grouting pressure head 10 will be housed is depressed on the mud cover face 3, and grouting pressure head 10 is communicated with iron mouth pore passage, after carrying out pressurize, connects grout machine and also opens ball valve 121, is in the milk thereby just can carry out iron mouth 2.
