Description
Technical field
The utility model relates to a kind of tunnel furnace flue, relates in particular to a kind of tunnel furnace flue that becomes the flue shape with plate member bent.
Background technology
Tunnel furnace flue is a kind of passage that flame in the stove and flue gas is transported to space outerpace, and flue is easily burnt by high temperature when bearing flame and high-temperature gas, so tunnel furnace flue all can use refractory material in the inside of flue, usually tunnel furnace flue adopts laying fireproof bricks, and the flue of building by laying bricks or stones comprises furnace roof and furnace wall.When building by laying bricks or stones; also to consider the specific environment of flue; its concrete external shape also will be determined according to external environment condition; flue often some special-shaped parts can occur like this; when building special-shaped part by laying bricks or stones, the man power and material that often will cost a lot of money, the time of building by laying bricks or stones is long; in case damage appears in special-shaped part, repair again difficulty very.
Build the defective that the flue stove exists by laying bricks or stones in order to overcome, Granted publication CN102042753A, Granted publication day is that the Chinese invention patent application on May 4th, 2011 discloses a kind of tunnel furnace flue and preparation method thereof, this flue comprises the anchoring hook that is arranged on main body plate inwall and the insulating with wire netting that is limited by anchoring hook, and the insulating surface spraying has refractory material.The weld bond area of anchoring hook is relatively large in this kind tunnel furnace flue, to being securely fixed on the main body plate, can not come off even if can guarantee the vibration that the refractory material that sprays is subject to travelling platform yet, not only can improve heating furnace production efficiency, reduce production costs.But also there is the shortcoming of himself in this invention: anchoring hook be shaped as V-arrangement, when linking to each other with insulating, the free end of its V-shaped part exposes insulating, it contacts with flame or high-temperature gas at first, its temperature is the highest, is easy to be burnt by high-temperature gas, in case high-temperature gas has burnt the free end that V-arrangement is seen, insulating and refractory masses just easily come off, and flue will be damaged.
The utility model content
In order to overcome defects, the utility model provides a kind of tunnel furnace flue, anchoring hook and the insulating of this tunnel furnace flue are close to, the temperature that its free end receives has passed to insulating and refractory masses, prevented that anchoring hook from being burnt out by high-temperature gas, thereby avoided coming off of insulating and refractory masses, greatly prolonged the service life of tunnel furnace flue.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Tunnel furnace flue, comprise the main body plate, be arranged on the anchoring hook of main body plate inwall and the insulating with wire netting that is limited by anchoring hook, described insulating surface spraying has one deck refractory masses, it is characterized in that: described anchoring hook comprises for the T shape structure fixed part of fixedly insulating and refractory masses with fixed part and is connected to connecting portion on the main body plate.
Described connecting portion is a cone, and the end that area is little is welded on the main body plate, and the end that area is large links to each other with fixed part.
The inwall of described main body plate is provided with the groove for the connecting portion welding.
The utlity model has following having a few:
1, the utility model anchoring hook comprise for the T shape structure fixed part of fixedly insulating and refractory masses and fixed part is connected to connecting portion on the main body plate, the fixed part of T shape structure can firmly be fixed on insulating and refractory masses on the main body plate, tunnel furnace flue is at when vibration refractory masses that also can not drop, because the fixed part of anchoring hook is T shape structure, the top of T shape structure is parallel with heat-resistant material layer, rather than the prominent protrusion of picture v-shaped structure and heat-resistant material layer, the top of T shape structure is when being subject to high temperature, sent heat to heat-resistant material layer and insulating, T shape structure can be not damaged because of localized hyperthermia, refractory masses in the flue and insulating just can not come off, so just improved the service life of anchoring hook, thereby improved the service life of tunnel furnace flue.
2, the connecting portion of the utility model anchoring hook is a cone, the end that area is little is welded on the main body plate, the end that area is large links to each other with fixed part, so just increased the bonding area of connecting portion and main body plate, make more firm being welded on the main body plate of anchoring hook, but also can increase the diameter of anchoring hook connecting portion, the reinforcing anchoring hook in a nearly step.Thereby guaranteed that effectively heat-resistant material layer and insulating can not come off, further prolonged the service life of tunnel furnace flue stove.
3, the inwall of the utility model main body plate is provided with the groove for connecting portion welding, and such design is in order to strengthen the fixation of anchoring hook and main body plate equally, and when anchoring hook being welded on the main body plate, is more prone to operate.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of anchoring hook;
Fig. 3 is the cross-section front view of Fig. 1;
Mark among the figure: 1, main body plate, 2, insulating, 3, anchoring hook, 31, fixed part, 32, connecting portion, 4, groove.
The specific embodiment
Such as Fig. 1 and Fig. 2, shown in Figure 3, tunnel furnace flue, the insulating 2 with wire netting that comprises main body plate 1, is arranged on the anchoring hook 3 on main body plate 1 inwall and limited by anchoring hook 4, described insulating 2 surface sprayings have one deck refractory masses, and described anchoring hook 3 comprises for the T shape structure fixed part 31 of fixedly insulating 2 and refractory masses with fixed part 31 and is connected to connecting portion 32 on the main body plate 1.Connecting portion 32 is a cone, and the end that area is little is welded on the main body plate 1, and the end that area is large links to each other with fixed part 31.Pass through the at interval groove 4 of preset distance of compacting or gas cutting on the surface of plate, and four grooves leading mutually are positioned on four angles of rhombus, then this plate member bent is become the flue shape, to form main body plate 1.
The fixed part 31 of T shape structure can firmly be fixed on insulating 2 and refractory masses on the main body plate 1, tunnel furnace flue is at when vibration refractory masses that also can not drop, because the fixed part 31 of anchoring hook 3 is T shape structure, the top of T shape structure is parallel with heat-resistant material layer, rather than the prominent protrusion of picture v-shaped structure and heat-resistant material layer, the top of T shape structure is when being subject to high temperature, sent heat to heat-resistant material layer and insulating, T shape structure can be not damaged because of localized hyperthermia, refractory masses in the flue and insulating 2 just can not come off, so just improved the service life of anchoring hook 3, thus the service life of having improved tunnel furnace flue.And the connecting portion 32 of anchoring hook 3 is a cone, the end that area is little is welded on the main body plate 1, the end that area is large links to each other with fixed part 31, so just increased the bonding area of connecting portion 32 with main body plate 1, make anchoring hook 3 more firm being welded on the main body plate 1, but also can increase the diameter of anchoring hook 3 connecting portions 32, the reinforcing anchoring hook 3 in a nearly step.Thereby guaranteed that effectively heat-resistant material layer and insulating 2 can not come off, and have further prolonged the service life of tunnel furnace flue stove.
