Abstract
The utility model relates to a vacuum double-layer groove cover which comprises an outer shell (1) and an inner shell (2), wherein the outer shell (1) and the inner shell (2) form a sealed vacuum cavity body (3); a supporting plate (4) is arranged in the cavity body (3). According to the vacuum double-layer groove cover, the vacuum cavity body (3) between the outer shell (1) and the inner shell (2) has a very good effect of heat insulation, the influence of low air temperature in a workshop on the inner surface of the groove cover is avoided, the steam condensation temperature condition is no longer valid, condensation liquid dripping is radically prevented from being generated, drops are prevented from dripping on a steel belt, and the product quality is further guaranteed.
Description
Technical field
The utility model relates to a kind of groove lid, more particularly, relates to a kind of vacuum double groove lid.
Background technology
On the cold rolled strip steel production line, all technologies such as cleaning, plating that relate to the band steel have generally adopted the cell body kind equipment.This kind equipment generally all adds the tankage lid above cell body, overflow to prevent inner a large amount of steam.Because acid in the cell body, concentration of lye is bigger, at high temperature its acid, alkali become branch's volatilization, form acid, alkali mist with vapor evaporated in the actual production.The groove lid of available technology adopting is single layer structure, the weak point of this structure is, when temperature in the workshop is low, low temperature is transmitted to its internal surface from the groove exterior surface, and during the dew-point temperature of steam, steam just condenses into dew at the groove interior surface in reaching cell body, a large amount of condensations pool the drop of acidity or alkalescence, drip on the band steel, can cause being with the steel quality to descend, cause financial loss.
The utility model content
The technical problems to be solved in the utility model is, a kind of vacuum double groove lid that can avoid the steam condensation is provided.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of vacuum double groove lid, comprise shell and inner casing, described shell and inner casing are formed the enclosed vacuum cavity, and described inside cavity is provided with back up pad.
In vacuum double groove lid described in the utility model, described shell is provided with aspirating hole, and described aspirating hole is by the sealing plug shutoff.
In vacuum double groove lid described in the utility model, described sealing plug is rubber plug.
In vacuum double groove lid described in the utility model, the connection section of described shell and inner casing seals by seal gum.
In vacuum double groove lid described in the utility model, described back up pad is provided with ventilating pit.
In vacuum double groove lid described in the utility model, described back up pad is fixedly connected between described inner casing and the described shell.
Implement vacuum double groove lid of the present utility model, have following beneficial effect: the shell of the utility model vacuum double groove lid and the vacuum cavity between the inner casing can play well isolated heat conducting effect, stopped the influence of the low temperature in workshop to the groove interior surface, the temperature condition of steam condensation is no longer set up, fundamentally stopped the generation of condensation dropping liquid situation, avoided drop to drop onto on the steel band, quality product is more secure.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model vacuum double groove lid;
Fig. 2 is the sectional view of the utility model vacuum double groove lid.
Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1 and Figure 2, vacuum double groove lid of the present utility model is used for being installed in cell body 6 tops, and the groove lid comprises shell 1 and inner casing 2.Shell 1 and inner casing 2 are formed enclosed vacuum cavity 3, vacuum cavity 3 can play well isolated heat conducting effect, stopped the influence of the low temperature in workshop to the groove interior surface, the temperature condition of steam condensation is no longer set up, fundamentally stopped the generation of condensation dropping liquid situation, avoid drop to drop onto on the steel band of cell body 6 inside, quality product is more secure.Cavity 3 inside are provided with back up pad 4, prevent that shell 1 and inner casing 2 are crushed.Back up pad 4 can be fixed between inner casing 2 and the shell 1 by mode such as bonding, as to weld, rivet, be threaded.
Further, shell 1 is provided with aspirating hole, and aspirating hole is used for connecting pneumatic pump and makes vacuum.Aspirating hole can be by 5 shutoff of sealing plugs such as rubber plug.
Further, sealing effectiveness is filled to reach with heat-resisting, moisture-proof, corrosion resistant seal gum in the connection section slit of shell 1 and inner casing 2.
Further, on the back up pad 4 ventilating pit can be set, the manufacturing vacuum of being convenient to bleed.But be understandable that, when the size of back up pad 4 hour, ventilating pit is not set on the back up pad 4 can not influenced yet and vacuumize.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
