Abstract
The utility model belongs to the cold quick -witted field of ring especially relates to a sealing device for encircling cold aircraft bonnet, a sealing device for encircling cold aircraft bonnet, including a set of fan -shaped seal bottom plate, with the every perpendicular sealed riser of being connected of seal bottom plate, with the breast board that every seal bottom plate is connected, bottom surface middle part and seal bottom plate spot welding under the sealed riser of its characterized in that, just sealed riser both sides are fixed on seal bottom plate by fixed angle steel, and every seal bottom plate center department passes through a set of bolt assembly I and breast board fixed connection, and every seal bottom plate's both sides are connected with the breast board through a set of bolt assembly II. The utility model discloses simple structure, it is firmly durable, improved the connected mode of cover seal bottom plate and breast board, also improved the connected mode of seal bottom plate and sealed riser, the effectual solution because problem that waste gas that the thermal energy inequality of cold aircraft bonnet of ring arouses leaked has improved its life has guaranteed that the cold machine of ring improves waste heat utilization, reduces the flue gas and leaks, improves the environment.
Description
Technical field
The utility model belongs to central cooler field, especially relates to a kind of sealing device for central cooler cover.
Background technology
Central cooler is one of visual plant of SINTERING PRODUCTION technique, in order to effectively reclaim waste gas residual heat, energy-conserving and environment-protective under the abundant cooling condition of sintering deposit, should reduce as far as possible leak out between central cooler cover seal base and breast board.In original structure between the seal base of cover and breast board, between sealing riser and seal base, be all continuous welding relation.Due to the conduction of heat of sintering deposit, make sealing riser and seal base all can produce heat expansion or contraction along with the change of sintering deposit temperature, sealing riser, seal base and breast board, because being subject to position influence, the heat accepted is different, make deflection inconsistent, deformation inequality causes occurring weld seam or cracking, structure is destroyed, the hot waste gas in central cooler can be made like this to leak, have impact on the collection of waste heat, and around revolving body, Dust Capacity also can increase, cause environmental pollution, central cooler repair and maintenance amount also strengthens simultaneously.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, firm and durable and can eliminate due to thermal deformation cause the sealing device for central cooler cover of structural deterioration.
The purpose of this utility model is realized by following technical proposals:
Sealing device for central cooler cover of the present utility model, comprise one group of fan-shaped seal base, sealing riser connected vertically with every block seal base, the breast board be connected with every block seal base, it is characterized in that in the middle part of described sealing riser bottom surface with described seal base means of spot welds, and described sealing riser both sides are fixed on described seal base by fixing angle steel
Every block seal base center is fixedly connected with described breast board by one group of bolt assembly I, the both sides of every block seal base are connected with described breast board by one group of bolt assembly II, described bolt assembly I comprises screw bolt and nut, and described bolt assembly II comprises bolt, nuts and bolt sleeve pipe.
The length of described bolt sleeve is greater than the thickness of slab sum of described seal base and breast board.
One group of described bolt assembly I number is 4-6 bolt assembly I.
One group of described bolt assembly II number is 4-6 bolt assembly II.
Advantage of the present utility model:
Sealing device structure for central cooler cover of the present utility model is simple, firm and durable, improve the connected mode of cover seal base and breast board, also improve the connected mode of seal base and sealing riser, effectively solve the problem of the uneven exhaust gas leakage caused of thermal expansion due to central cooler cover, improve its service life, ensure that central cooler improves UTILIZATION OF VESIDUAL HEAT IN, reduce smoke spillage, environmental protect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of the utility model Fig. 1.
Detailed description of the invention
Detailed description of the invention of the present utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, 2, sealing device for central cooler cover of the present utility model, comprise one group of fan-shaped seal base 3, sealing riser 1 connected vertically with every block seal base 3, the breast board 7 be connected with every block seal base 3, it is characterized in that in the middle part of described sealing riser 1 bottom surface with described seal base 3 means of spot welds, and described sealing riser 1 both sides are fixed on described seal base 3 by fixing angle steel 2
Every block seal base 3 center is fixedly connected with described breast board 7 by one group of bolt assembly I, the both sides of every block seal base 3 are connected with described breast board 7 by one group of bolt assembly II, described bolt assembly I comprises bolt 4 and nut 6, and described bolt assembly II comprises bolt 4, nut 6 and bolt sleeve 5.
The length of described bolt sleeve 5 is greater than the thickness of slab sum of described seal base 3 and breast board 7.
One group of described bolt assembly I number is 4-6 bolt assembly I.
One group of described bolt assembly II number is 4-6 bolt assembly II.
As shown in Figure 2, in the middle part of sealing riser 1 bottom surface, shorter scope and seal base 3 are welded and fixed, and both sides have fixing angle steel 2 to be clipped in the middle by sealing riser 1, fixing angle steel 2 position-limiting actions.Sealing riser 1, when being heated uneven generation thermal expansion, centered by welding portion, extending to two ends and expands.Owing to only having mid portion to carry out means of spot welds, two ends are all free end, and then eliminate sealing riser 1 and the uneven structural deterioration brought of seal base 3 thermal deformation.In addition, the seal base 3 of cover is multiple fanlike die block composition, seal base 3 is symmetrical with center line, in direction circumferentially, intermediate distribution 4-6 plain bolt hole, use bolt 4 to be connected with breast board 7 with nut 6, its Main Function is fixing seal base plate 3, makes seal base 3 and breast board 7 that the change of relative position not occur in this interval.In addition, seal base 3 both sides each several part is provided with the bolt hole of 2-3 larger aperture, is used for offsetting the expand deformation that causes of upper and lower steel plate hot uneven.As shown in Figure 2, adopt bolt 4, nut 6 is connected breast board 7 and seal base 3 with bolt sleeve 5, the length of bolt sleeve 5 is larger than sealing plate 3 and breast board 7 thickness of slab sum, the fastening force of bolt 4 is made to act on bolt sleeve 5, this structure merely defines the displacement of vertical direction, and horizontal direction can be slided.Because aperture is comparatively large, and then the thermal deformation counteracting upper and lower two boards is uneven.This structure can still keep good sealing state when being heated, and makes waste gas obtain sufficient utilization.
