Abstract
The utility model provides a safety device for preventing foreign body from blocking, comprising a horizontal pipeline and a control valve on the pipeline, a vertical pipeline connected with the horizontal pipeline and an abutting joint at the upper end of the vertical pipeline; the safety device is characterized in that: a baffle plate which inclines downwards is internally arranged at the upper end of the combination part of the horizontal pipeline and the vertical pipeline, and an outlet with a sealing cover is arranged at the lower end of the vertical pipeline. The dropped foreign body can be led in the outlet at the lower end of the vertical pipeline by the baffle plate which inclines downwards, and is exhausted at regular intervals, thereby radically avoiding the foreign body from entering the horizontal pipeline to block the control valve, so as to cause gas leakage to cause severe safety accidents such as gas poisoning, gas explosion and the like, eliminating safety hazards of cold-rolling annealing furnace and ensuring safe production; a protective cover is not needed to be arranged on the abutting joint, thereby reducing the labor intensity of workers, preventing the abutting joint from being damaged, ensuring the normal production of the annealing furnace and improving the production efficiency.
Description
Technical field
Present technique relates to cold rolling full-hydrogen hood-type annealing furnace foreign matter in production reality and falls into and prevent the jam gas valve, causes the Controlling System malfunction and accidents caused a kind of technological innovation.Belong to perhydro bell-type annealing utility model technical field.
Background technology
When the work of cold rolling full-hydrogen hood-type annealing furnace, the coal gas of being sent here by horizontal pipe is sent into the burner on the annealing furnace heating mantles through control valve, bend pipe, straight tube, butt junction, after heating mantles is heated, finishes the anneal that steel in the stove are carried out.Because heating mantles is the replacing formula, promptly when needs are annealed by after the crane immigration, be communicated with gas pipe by butt junction, the unlatching by control valve again provides to heat to heating mantles and uses coal gas; When not needing to heat, by crane heating mantles is removed again.For preventing that removing the back foreign matter enters the normal open and close that gas pipe influences control valve through butt junction, serious accidents such as the carbon monoxide poisoning that closely causes gas leak and cause, gas explosion, the solution of prior art is: establish a cover in the butt junction that links to each other with the coal gas air-supply duct, lock after covering butt junction with this cover again.But the problem that this mode is brought is: adorn at every turn, hang that heating mantles all must manually be uncapped, locking closure, both influenced cold rolled annealed production efficiency, increase working strength of workers, cause the damage of coal gas butt junction again easily, therefore be necessary prior art is improved.
Summary of the invention
For overcoming the prior art above shortcomings, the utility model provides a kind of security device of anti-foreign matter jam.
The utility model is finished by following technical proposal: a kind of security device of anti-foreign matter jam, comprise the control valve on horizontal pipe and the pipeline, the butt junction of vertical ducting that links to each other with horizontal pipe and vertical ducting upper end, it is characterized in that at the built-in downward-sloping baffle plate in the upper end of horizontal pipe and vertical ducting joint portion, and be provided with the outlet of with closure in the vertical ducting lower end, so that foreign matter is in butt junction enters vertical ducting the time, slips into the vertical ducting lower end and regularly discharge by downward-sloping baffle plate.Prevent that effectively foreign matter from entering horizontal pipe and the jam control valve.
Described horizontal pipe links to each other with vertical ducting by bend pipe, the built-in downward-sloping baffle plate in the upper end of bend pipe nook.
Described horizontal pipe directly links to each other with vertical ducting, at the built-in downward-sloping baffle plate in the level and the upper end of vertical junction.
Described downward-sloping baffle plate is made as arc, so that the foreign matter that falls is imported vertical ducting lower end and discharge regularly.
The utility model compared with prior art has following advantage and effect: adopt such scheme, the foreign matter that falls into can be imported the relief outlet of vertical ducting lower end through downward-sloping baffle plate, do regular discharge, fundamentally avoided foreign matter to enter horizontal pipe and behind the jam control valve, cause gas leak and cause the generation of serious accidents such as carbon monoxide poisoning, gas explosion, eliminate the potential safety hazard of cold rolled annealed stove, ensure production safety; Need not in butt junction, to add a cover again shield cap, reduce working strength of workers, prevent that butt junction is damaged, ensure the ordinary production of annealing furnace, enhance productivity.

Fig. 3 is an installation site of the present utility model structure iron.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The security device of the anti-foreign matter jam that the utility model provides, comprise the control valve 2 on horizontal pipe 1 and the pipeline 1, control valve 2 is a Pneumatic butterfly valve in fact, the butt junction 3 of vertical ducting 4 that links to each other with horizontal pipe 1 and vertical ducting 4 upper ends, at the built-in downward-sloping baffle plate 5 in the upper end of horizontal pipe and vertical ducting joint portion, and be provided with the outlet 6 of with closure 7 in vertical ducting 4 lower ends, horizontal pipe links to each other with vertical ducting 4 by bend pipe 8, the built-in downward-sloping curved baffle 5 in upper end in the nook of bend pipe 8 is as Fig. 1;
Described horizontal pipe 1 directly links to each other with vertical ducting 4, at the upper end built-in downward-sloping curved baffle 5 of horizontal pipe 1 with the vertical ducting junction, as Fig. 2.
The butt junction 10 of gas pipe 12 lower ends on the butt junction 3 of vertical ducting 4 upper ends and the annealing furnace heating mantles 16 links to each other, gas pipe 12 is provided with control valve 11, gas pipe 12 upper ends are communicated with burner 17 on the annealing furnace heating mantles 16, so that annealing coal gas heat energy to be provided to heating mantles 16,15 is inner cover, 14 for carrying out the coil of strip of anneal, and 13 is the hanger at heating mantles 16 tops, as Fig. 1.
During annealing, open Pneumatic butterfly valve 2 on the horizontal pipe by computer control, the burner 17 that makes coal gas enter annealing furnace heating mantles 16 burns, thereby to the cold rolled strip heating of annealing; Heating is closed Pneumatic butterfly valve 2 by computer control after finishing, and heating mantles 16 hangs the back by overhead traveling crane and changes cooling cowl, enters cooling program; Hang back again heating period from this moment to heating mantles 16 next time, in the time of in the docking port 3 that has foreign matter from vertical gas pipe 4 upper ends enters pipe,,, regularly open and cover 7 and can discharge the relief outlet 6 of its importing vertical ducting 4 lower ends by curved baffle 5.
