Abstract
The invention discloses a lifting check curtain structure of a seal box. The lifting check curtain structure comprises a seal box upper cover (2), a fire retardance plug (1) is installed in a stepped hole of the seal box upper cover (2) in a matched mode, an asbestos pad (4) is arranged between the stepped hole of the seal box upper cover (2) and the fire retardance plug (1) in a padding mode, a press plate (6) and the seal box upper cover (2) are connected through bolts (7), the press plate (6) is arranged at the top of the fire retardance plug (1) in a pressed mode, and the fire retardance plug (1), the asbestos pad (4) and the seal box upper cover (2) are closely compacted on the stepped hole of the seal box upper cover (2) by screwing down screws (5). The structure is simplified, an inverted-V baffle and a check curtain supporting sliding chute of the upper portion are omitted, and the possibility of blocking is eliminated. The seal performance of the fire retardance plug and the seal box is improved for the structure in multiple modes, and the width of a check curtain lifting channel is reduced.
Description
Technical field
The present invention relates to floatation glass production line watertight chest lifting check apron field, belong to a kind of watertight chest lifting check apron structure.
Background technology
Conventional seals case lifting check apron liftway adopts on check apron establishes reverse V-shaped fire-proof plate to seal; The surface of the watertight chest simultaneously above lifting check apron passage placed cylindrical back-fire relief plug, and there is comparatively wide arc gap between the elevating lever of itself and casing and check apron, sealing effectiveness is not good.In actual production process, it is even stuck because temperature distortion causes check apron to be elevated blocked portion on the contrary that the rectangle check apron above reverse V-shaped fire-proof plate and check apron supports chute, also causes in production simultaneously and change check apron difficulty from watertight chest sidepiece.Up to now, also not for the optimization design of structure herein.
Summary of the invention
The present invention mainly provides a kind of watertight chest lifting check apron structure, solves check apron and changes difficult, that back-fire relief plug sealing property is not enough, lifting check apron is stuck problem.
Technical scheme of the present invention is as follows:
A kind of watertight chest lifting check apron structure, include watertight chest upper cover 2, coordinate in watertight chest upper cover 2 shoulder hole and back-fire relief plug 1 is installed, asbestos pad 4 is equipped with between the shoulder hole of watertight chest upper cover 2 and back-fire relief plug 1, pressing plate 6 is connected by bolt 7 with watertight chest upper cover 2, pressing plate 6 is pressed on back-fire relief plug 1 tip position, by tighten the screws 5 by back-fire relief plug 1, asbestos pad 4 and watertight chest upper cover 2 tightly compacted in the shoulder hole of watertight chest upper cover 2, check apron elevating lever 8 is sliding combined with in back-fire relief plug 1, check apron elevating lever 8 upper end is connected with elevator 12, check apron elevating lever 8 lower end is provided with check apron 10, curtain plate 11, pressure ring 9.
Quadrel cotton cord 3 is embedded in the annular seal groove of back-fire relief plug 1.
On original structure basis, cancel the reverse V-shaped baffle plate on check apron and the check apron that made by rectangular pipe supports chute, simultaneously the width of also constriction check apron liftway.Back-fire relief plug is the long lumbar shape of multi-step, intermediate lands increases an annular seal groove, for installing quadrel cotton cord; Watertight chest offers associated ladder waist shaped hole in installation back-fire relief plug position, and back-fire relief plug coordinates with ladder waist shaped hole and is running fit, for structure leaves certain expansion space; Back-fire relief is just symmetrical arranged multiple pressing plate beyond the Great Wall, and this pressing plate is fixed by bolt and casing, and the other side compresses back-fire relief plug by jackscrew, makes the end face of back-fire relief plug, sealing asbestos pad and ladder waist shaped hole tightly compacted.When check apron is changed in normal production, the pressing plate jackscrew that back-fire relief is square beyond the Great Wall unclamps, and extracts back-fire relief plug out, extracted out by check apron, there is not blocked portion phenomenon, and check apron difficulty of processing also reduces greatly above watertight chest.
Advantage of the present invention is: present invention employs and change the mode of check apron from watertight chest top, and check apron is changed more efficient and convenient, minimum by drop to the impact of producing; Original check apron supports chute and is processed by elongated rectangular steel pipe, there is larger machining stress, especially easily deforms under worst hot case; New check apron simplifies the structure, and the baffle plate of falling V and the check apron that eliminate top support chute, eliminate the possibility that blocked portion occurs.Be the sealing property that structure improves back-fire relief plug and watertight chest by multiple sealing means; Narrow the width of check apron liftway.
In order to more detailed explanation the present invention, followingly accompanying drawings provide a most preferred embodiment of the present invention.
Accompanying drawing illustrates:
Fig. 1 is former watertight chest lifting check apron structural representation.
Fig. 2 is watertight chest of the present invention lifting check apron structural representation.
Fig. 3 is vertical view of the present invention.
Embodiment:
As Fig. 2, shown in Fig. 3, a kind of watertight chest lifting check apron structure, include watertight chest upper cover 2, coordinate in watertight chest upper cover 2 shoulder hole and back-fire relief plug 1 is installed, asbestos pad 4 is equipped with between the shoulder hole of watertight chest upper cover 2 and back-fire relief plug 1, quadrel cotton cord 3 is embedded in the annular seal groove of back-fire relief plug 1, pressing plate 6 is connected by bolt 7 with watertight chest upper cover 2, pressing plate 6 is pressed on back-fire relief plug 1 tip position, by tighten the screws 5 by back-fire relief plug 1, asbestos pad 4 and watertight chest upper cover 2 tightly compacted in the shoulder hole of watertight chest upper cover 2, check apron elevating lever 8 is sliding combined with in back-fire relief plug 1, check apron elevating lever 8 upper end is connected with elevator 12, check apron elevating lever 8 lower end is provided with check apron 10, curtain plate 11, pressure ring 9, when changing check apron 10, the bolt 5 above back-fire relief plug 1 is unclamped and again pressing plate 6 is removed, by 3 elevators of top, 3 check apron elevating levers 8, back-fire relief plug 1, check apron 10 are mentioned in the lump above watertight chest, the curtain plate 11 changed by needs below check apron is removed and the curtain plate more renewed from pressure ring 9, then installs by above-mentioned contrary step.
As shown in Figure 1, original structure check apron structure, include back-fire relief plug 1, watertight chest upper cover 2, check apron elevating lever 8, check apron support chute 13, check apron 10, back-fire relief plug 1 is cylindrical, and there is circular hole centre, and inner filling alumina silicate fiber felt, is placed on check apron elevating lever.The inner check apron top of watertight chest is provided with reverse V-shaped baffle plate, the flame of watertight chest inside is had to the function of prevention.This sealed structure mainly cooperatively interacts by back-fire relief plug 1 and baffle plate and seals, but for avoiding baffle plate expanded by heating stuck, usually can leave certain expansion clearance, does not form complete trim.When changing check apron in production, extract difficulty out because temperature distortion and its liftway generation blocked portion under the reverse V-shaped baffle plate of check apron and check apron support chute high temperature cause it to support detent sides from check apron, cause interference to normal production.
