Abstract
The utility model provides a broken sediment ware quick change rifle head of RH, including the rifle body and rifle head, processing threaded through-hole on the position that is close to rifle head afterbody, the rifle body corresponds the position and also processes threaded through-hole, and the bolt-up connection of rifle head through-hole and rifle body through-hole through having the external screw thread. The utility model discloses can the broken sediment ware rifle head of quick replacement, need not the blowing out, the operation is simple, safe and reliable, and reducible change operation's danger improves the broken sediment ware rifle head of RH and changes efficiency and RH operation rate, reduction in production cost.
Description
Technical field
The utility model belongs to steel-making refining equipment field, more particularly to it is a kind of can fast online replacement RH broken slag device it is fast
Change pipette tips.
Background technique
RH purifier gradually plays a significant role in external refining.After RH insertion tube immerses molten steel, on steel slag liquid level
Floating, top steel slag easily crusts under air environment, is needed before thermometric, sampling using broken slag device break.Since broken slag device is frequent
It is inserted into steel slag, broken slag device pipette tips dross is serious, cannot use, need replacing pipette tips.Previous broken slag device pipette tips and gun body
Original connection type be welding, when replacement, needs blowing out, cooling, cutting, welding, and duty cycle is longer, operation risk compared with
It is high.
Summary of the invention
The utility model be intended to provide one kind can quick-replaceable broken slag device pipette tips at any time, the RH break of operating rate can be improved
Device quick change pipette tips.
For this purpose, the technical solution that the utility model is taken are as follows:
A kind of RH broken slag device quick change pipette tips, including gun body and pipette tips are machined with band spiral shell on the position close to pipette tips tail portion
The through-hole of line, gun body corresponding position are also machined with threaded through-hole, and pipette tips through-hole passes through with gun body through-hole with externally threaded
Bolt fastening connection.
Pipette tips tail portion through-hole is away from 30~100mm of pipette tips tail end.
The through-hole diameter of gun body and pipette tips is 5~20mm.
The utility model has the following beneficial effects:
The utility model can quick-replaceable broken slag device pipette tips at any time, be not necessarily to blowing out, operation is simple, securely and reliably, can subtract
The risk of few replacement operation is greatly improved RH broken slag device pipette tips replacement efficiency and RH operating rate, reduces production cost.
Detailed description of the invention
Fig. 1 is RH broken slag device quick change pipette tips diagrammatic cross-section.
In figure: gun body 1, bolt 2, pipette tips 3.
Specific embodiment
As seen from Figure 1, the utility model RH broken slag device quick change pipette tips are to be made of gun body 1, bolt 2, pipette tips 3.Away from
It is 10mm band internal thread through-hole that diameter is processed on position from 3 tail portion 50mm of pipette tips, while in 1 corresponding position of gun body
Process same diameter and with internal thread through-hole, then with through-hole internal diameter meet with externally threaded bolt 2, by rifle
First 3 are fixed in gun body 1.
Specific replacement step are as follows: broken slag device is screwed in into change bit before replacement, bolt 2 is pulled up, useless pipette tips are removed；By pipette tips
In 3 insertion gun bodies 1, it is inserted into and is locked using bolt 2, and tighten bolt 2；Broken slag device after replacement is threaded to processing position, it is upper and lower, preceding
After act, detection 3 non-loosening of pipette tips, displacement, can break use.
Claims (3)
1. a kind of RH broken slag device quick change pipette tips, including gun body and pipette tips, which is characterized in that add on the position close to pipette tips tail portion
Work has threaded through-hole, and gun body corresponding position is also machined with threaded through-hole, and pipette tips through-hole is with gun body through-hole by having
Externally threaded bolt fastening connection.
2. RH broken slag device quick change pipette tips according to claim 1, which is characterized in that pipette tips tail portion through-hole is away from pipette tips tail end 30
~100mm.
3. RH broken slag device quick change pipette tips according to claim 1, which is characterized in that the through-hole diameter of gun body and pipette tips is
5~20mm.
