Abstract

The invention discloses a cold air suction valve for sintering of a main air drafting and guiding pipe. The cold air suction valve comprises a valve body and an insertion board. The longitudinal section of the inner wall of the valve body is rectangular. Connecting flanges are arranged at the two ends of the valve body respectively. The inner side of the top wall of the valve body is provided with an upper sliding groove in the width direction. The inner side of the bottom wall of the valve body is provided with a lower sliding groove in the width direction. The top of the insertion plate is located in the upper sliding groove. The bottom of the insertion plate is located in the lower sliding groove. A rolling body is arranged between the bottom of the insertion plate and the bottom of the lower sliding groove. The width of the insertion plate is greater than or equal to the width of the inner wall of the valve body. Due to the fact that the insertion plate slides freely in the upper sliding groove and the lower sliding groove, the rolling body can guarantee flexible sliding of the insertion plate, and the sliding direction of the insertion plate is the horizontal direction and is perpendicular to the air inlet direction, in the opening process and the closing process of the cold air suction valve, the valve body can not vibrate, both the opening process and the closing process are very stable, equipment is not prone to damage, and the service life is long.

Description

Sinter the cold wind inlet valve of main convulsion airway
Technical field
The present invention relates to smelting SINTERING TECHNOLOGY field, more particularly, to a kind of cold wind sintering main convulsion airway sucks Valve.
Background technology
In sintering production process, the high-temp waste gas of generation enter electric cleaner by main convulsion airway, are then passed through leading Air exhauster discharges.Because the fluctuation of the factors such as mixture moisture, coke fines size, quick lime proportioning causes sintering deposit outlet temperature Too high, high-temperature gas enters main exhauster, and in main convulsion airway, flue-gas temperature exceedes what the equipment such as blower fan can bear sometimes Temperature, high-temperature gas, for a long time through equipment such as blower fans, can cause equipment performance largely to be damaged, or even thing occurs Therefore.The effect of cold wind inlet valve is exactly the timely gas temperature adjusting in main convulsion airway, protection equipment.
As shown in figure 1, after cold wind is introduced into deafener 1 noise reduction, entering cold wind inlet valve 2, subsequently into main convulsion inducing QI Pipe 3.In prior art, the cold wind inlet valve sintering main convulsion airway, all using turnover plate type structure, as shown in Figures 2 and 3, turns over Board-like cold wind inlet valve, including valve body 20, turnover panel 21, valve seat 22, connecting plate 23, rotating plate shaft 24, rocking arm 25, connecting rod 26 and electronic Actuator 27, electric operator 27 band motion rocker arm 25, connecting rod 26, rotating plate shaft 24 and connecting plate 23 rotate, thus realizing turning over The unlatching of plate 21 and closure.
Current of electric can be made to increase even overload because a large amount of cold wind enter pipe network system, and quick refrigeration is to equipment originally Body will also result in some infringements, therefore, blends and need to slowly open turnover panel 21 during cold wind, the opening angle of turnover panel 21 is at 15 °~40 ° It is advisable;The opening direction of turnover panel 21 is in face of air intake direction, and air intake resistance is big and unstable, and turnover panel 21 drives whole valve body 20 Vibrations, wherein, when 30 ° about, vibrations are more violent, and equipment is easily damaged for the opening angle of turnover panel 21, wherein, electronic execution Mechanism 27 is the most fragile.
It is provided with rubber weather strip in the groove of valve seat 22, because rubber weather strip is in the groove be embedded in valve seat 22, Fixation is not firm, and in valve body 20 strenuous vibration, rubber weather strip easily comes off;When turnover panel 21 is closed it is impossible to ensure turnover panel 21 are fitted tightly with rubber weather strip, and rubber weather strip easily damages.In valve body 20 strenuous vibration, connecting plate 23, rotating plate shaft 24th, the part such as rocking arm 25 and connecting rod 26 is easily deformed and ruptures, and causes to paste between turnover panel 21 and valve seat 22 sternly, leaks out serious.
Therefore, there is problems in that turnover panel opens difficulty, in opening process, valve body produces relatively turnover plate type cold wind inlet valve Big vibrations, are easily damaged equipment, and service life is short;Sealing is poor.
Content of the invention
The technical problem to be solved is to provide a kind of easy main convulsion airway of sintering opened and close Cold wind inlet valve, is not in significant shock during unlatching and closure, long service life.
The present invention solves the cold wind inlet valve of the main convulsion airway of sintering that its technical problem adopted, and includes valve body and slotting Plate, the longitudinal cross-section of described valve interior wall is rectangle, is provided with adpting flange at the two ends of described valve body, on described valve body top It is provided with upper hopper chute inside wall in the width direction, be provided with gliding groove in the width direction in described valve body inside bottom wall, described slotting The top of plate is located in upper hopper chute, and the bottom of described plate is located in gliding groove, the bottom of plate and gliding groove bottom land it Between be provided with rolling element, the width of the width >=valve interior wall of described plate.
Further, described rolling element is arranged in gliding groove.
Further, described rolling element is arranged on the bottom of plate.
Further, the opening in upper hopper chute is provided with fixed plate, is filled with close in the gap location of upper hopper chute and plate Strip of paper used for sealing, described sealing strip is supported by fixed plate.
Further, described sealing strip is graphite bar.
Further, described fixed plate is connected with upper hopper chute by bolt.
Further, also driving means are included, described driving means are connected with plate, described driving means drive plate to exist Motion in upper hopper chute and gliding groove.
Further, described driving means are Electrohydraulic push rod.
Further, described adpting flange is provided with bolt hole.
The invention has the beneficial effects as follows: the present invention sintering main convulsion airway cold wind inlet valve, due to plate be In upper hopper chute and gliding groove slidably, and rolling element can ensure that plate easy slide, and the glide direction of plate is Horizontal direction and vertical with air intake direction, therefore, in unlatching and the closing course of cold wind inlet valve, valve body is not in vibrations Phenomenon, opens and closing course is all very steady, and equipment should not damage, long service life.
