Abstract
The utility model discloses a blast furnace gas bag collector quick -opening manhole, include manhole nipple joint, seal bottom plate and the manhole cover of fixing through a plurality of sets of fastening bolt and manhole nipple joint, seal bottom plate is located between manhole nipple joint and the manhole cover, rotation supporting mechanism and manhole nipple joint swing joint are passed through to manhole cover one end, seal bottom plate has the groove structure who is used for placing the sealing washer, the edge of manhole cover is equipped with a plurality of checkpost and is used for blocking fastening bolt, fastening bolt includes nut, eye bolt, pivot and fixes 2 otic placodes on the manhole nipple joint, the eye bolt passes through the pivot to be fixed on the manhole nipple joint. Fastening bolt is small in quantity this quick -opening manhole structure, thus the time of opening the manhole and closing the manhole that has significantly reduced save repair time, still can avoid losing of bolt, nut, improve dust remover maintenance efficiency.
Description
Technical field
The utility model relates to blast furnace gas pocket type dust removing device quick opening manhole.
Background technology
Blast furnace gas is blast furnace ironmaking by product, belongs to hypertoxic, flammable, dust-laden, high pressure, high-temperature gas, by using after sack cleaner filtration, purification.Blast furnace gas pocket type dust removing device is circular tube structure, and fly-ash separator is provided with inspection manhole, facilitates personnel to enter fly-ash separator inside and changes filter bag.Original manhole is typical circular manhole, is made up of flange and blind flange, and by 20 cover bolted sealings.The shortcoming of this manhole is: 1, bolt quantity is more, makes to open and close the manhole used time longer, adds the repair time of fly-ash separator; 2, bolt, nut, pad remove easy loss.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of blast furnace gas pocket type dust removing device quick opening manhole, can avoid the loss of bolt, nut, and manhole opening time is short thus save the repair time, and easy to use, sealing is tight.
The utility model is by the following technical solutions: blast furnace gas pocket type dust removing device quick opening manhole, comprise manhole pipe nipple, seal base and the manhole plate fixed by some cover holding bolts and manhole pipe nipple, described seal base is between manhole pipe nipple and manhole plate, described manhole plate one end is flexibly connected with manhole pipe nipple by rotary support mechanism, described seal base has the groove structure for placing sealing-ring, described manhole plate edge is provided with several clamps for blocking holding bolt, described holding bolt comprises nut, strap bolt, pivot pin and 2 otic placodes be fixed on manhole pipe nipple, described strap bolt is fixed on manhole pipe nipple by pivot pin.
Further, described manhole plate is provided with stiffening web and handle.The intensity of manhole plate can be improved and be easy to open manhole.
Further, described nut termination is provided with closure plate.Prevent water inlet in nut from getting rusty.
Further, described holding bolt has 8 covers.Greatly reduce the time of opening manhole and closing manhole.
The utility model has the advantages that: 1, quick opening manhole's holding bolt quantity is from original 20 covers, is reduced to 8 covers, greatly reduces the time opening and closing manhole, improve fly-ash separator overhaul efficiency.2, strap bolt is fixed on manhole pipe nipple by pivot pin, can rotate again around pivot pin simultaneously, makes nut when not twisting off from bolt, departing from, preventing nut from losing by rotating from manhole plate clamp.3, nut termination increases closure plate, can prevent water inlet in nut from getting rusty.4, sealing-ring is placed in the groove of seal base, is sealed by tightened bolt presses, and groove structure can ensure the right alignment of sealing-ring and manhole, facilitates the installation of sealing-ring simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of the utility model manhole plate;
Wherein, 1, manhole pipe nipple, 2, seal base, 3, manhole plate, 4, rotary support mechanism, 5, sealing-ring, 6, clamp, 7, nut, 8, strap bolt, 9, pivot pin, 10, otic placode, 11, stiffening web, 12, handle, 13, closure plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described, but protection domain of the present utility model is not limited thereto.
As depicted in figs. 1 and 2, blast furnace gas pocket type dust removing device quick opening manhole, the manhole plate 3 comprising manhole pipe nipple 1, seal base 2 and fixed by 8 cover holding bolts and manhole pipe nipple 1, seal base 2 is between manhole pipe nipple 1 and manhole plate 3, manhole plate 3 one end is flexibly connected with manhole pipe nipple 1 by rotary support mechanism 4, seal base 2 is provided with groove structure, for placing sealing-ring 5, sealed by tightened bolt presses, groove structure can ensure sealing-ring 5 and the right alignment of manhole, also facilitates the installation of sealing-ring.The edge of manhole plate 3 is provided with 8 U-shaped clamps 6 for blocking holding bolt, and manhole plate 3 is provided with stiffening web 11 and handle 12, and stiffening web can improve the intensity of manhole plate; Handle is used as handle when opening manhole.Holding bolt comprises nut 7, strap bolt 8, pivot pin 9 and is welded on 2 otic placodes 10 on manhole pipe nipple 1, and strap bolt 8 is fixed on manhole pipe nipple 1 by pivot pin 9, can rotate again around pivot pin simultaneously; In order to improve nut strength, nut 7 can adopt super thick nut.This fastening bolt structure can make nut 7 when not twisting off from bolt, is rotated by strap bolt 8 around pivot pin 9, holding bolt is departed from from manhole plate clamp, and then prevents nut from losing.
Nut 7 termination is provided with closure plate 13.Prevent water inlet in nut from getting rusty.
Quick opening manhole's holding bolt quantity, from original 20 covers, is reduced to 8 covers, greatly reduces the time of opening manhole and closing manhole.
