Abstract
The utility model provides a waste incinerator that compound prefabricated section of utilization was built by laying bricks or stones, includes: furnace body, lifting blade and lifting blade support, the internal surface of furnace body be equipped with the compound prefabricated section of a plurality of row along the length of drum direction, compound prefabricated section between be equipped with anchor nail, furnace body internal surface between the compound prefabricated section is equipped with the refractory fiber blanket, refractory castable has been pour to the higher authority of refractory fiber blanket, an area raise the rotation waste incinerator of material device because pouring material adopts the one -piece casting, the prefabricated section through the welding of anchor hook on the barrel and have the protection of primary and secondary groove, even local solder joint sealing off in service or pouring material peel off, also unlikely monoblock prefabricated section or the pouring material large tracts of land of causing drops, keeps the steady in a long -term of refractory material to use.
Description
technical field:
The utility model relates to a kind of incinerator utilizing composite precast block to build by laying bricks or stones.
background technology:
The structure of swinging incinerator, the method for operation and environment for use are similar to common high temperature rotary kiln, are mainly used to burn the refuse such as urban life, medical waste, and in cylinder, flue-gas temperature is 800 ~ 1200 DEG C.
For being used for, burning is lived, the swinging incinerator of medical waste, because the rubbish proportion entering cylinder is comparatively light, volume disperses and moisture is larger, equipment de-sign personnel have begun through and arranged heat resisting steel raising material unit in cylindrical shells, to reach the object of rapid draing, pyrolysis, burning, owing to being furnished with a lot of raising material units in cylindrical shell, give traditional single laying fireproof bricks mode and bring adverse effect, be in particular in the following aspects:
1) after adopting single laying fireproof bricks structure, because cylindrical shell rotates the huge tangential force effect produced, very easily rupture by local compression with the refractory brick of lifting blade contact site, come off, to such an extent as to cause whole system stop production to overhaul;
2), after adopting single laying fireproof bricks structure, in order to ensure to lay bricks tightly, prevent refractory brick brick-dropping, should not arrange any heat-barrier material between liner and cylindrical shell, fireproof brick inner lining overall thermal conductivity is higher, and cylindrical shell heat loss is large, is unfavorable for energy-conserving and environment-protective;
3) after adopting single laying fireproof bricks structure, all need neck brick to build by laying bricks or stones with lifting blade junction lining brick, every ring is laid bricks all several neck brick district, and each neck brick district even will process brick through repeatedly selecting brick, greatly delays construction speed;
utility model content:
In order to solve the problem, the utility model provides a kind of incinerator utilizing composite precast block to build by laying bricks or stones.
The utility model solves the technical scheme that its technical problem adopts:
A kind of incinerator utilizing composite precast block to build by laying bricks or stones, comprise: cylindrical shell, lifting blade and lifting blade support, the inner surface of described cylindrical shell is provided with some row composite precast block along barrel lenght direction, anchor studs is provided with between described composite precast block, between described composite precast block cylinder inner surface be provided with refractory fiber blanket, described refractory fiber blanket above built castable refractory.
The bottom of described composite precast block is provided with flame-retardant fibre board and anchoring hook, and the side of described composite precast block is respectively equipped with mother-son groove.
Described anchoring hook is fixed by welding and cylindrical shell.
Owing to adopting technical scheme as above, the utility model has following superiority:
A kind of incinerator utilizing composite precast block to build by laying bricks or stones described in the utility model, has following advantage:
1, because castable adopts one-piece casting, prefabricated section to be welded on cylindrical shell by anchoring hook and to have mother-son groove to protect, even if local solder joint sealing-off or castable are peeled off in operation, also unlikely monoblock prefabricated section or the castable large area of causing comes off, and keeps the long-term stability of refractory material to use;
2, owing to being prefabricated with flame-retardant fibre board in advance bottom prefabricated section, be also equipped with the less refractory fiber blanket of thermal conductivity between castable and cylindrical shell, drum surface temperature reduces greatly;
3, because prefabricated section is shaping in manufactory, scene only needs line arrangement welding, and loaded down with trivial details both without neck brick, also need not arrange special castable template, greatly shorten construction period;
4, because prefabricated section and castable are fixed on cylindrical shell by anchoring piece, incinerator, in intensification or temperature-fall period, is not drawn lots by refractory brick, is fallen brick and affect, and with the running of any kiln speed, can facilitate execute-in-place.

In figure: 1, composite precast block; 2, refractory fiber blanket; 3, castable refractory; 4, anchor studs; 5, lifting blade; 6, lifting blade support; 7, flame-retardant fibre board; 8, anchoring hook; 9, mother-son groove; 10, refractory brick; 11, cylindrical shell.
detailed description of the invention:
Can explain the utility model in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples;
A kind of incinerator utilizing composite precast block to build by laying bricks or stones described by reference to the accompanying drawings, comprise: cylindrical shell 11, lifting blade 5 and lifting blade support 6, the inner surface of described cylindrical shell 11 is provided with some row composite precast block 1 along barrel lenght direction, anchor studs 4 is provided with between described composite precast block 1, between described composite precast block 1 cylindrical shell 11 inner surface be provided with refractory fiber blanket 2, described refractory fiber blanket 2 above built castable refractory 3.
The bottom of described composite precast block 1 is provided with flame-retardant fibre board 7 and anchoring groove 8, and the side of described composite precast block 1 is respectively equipped with mother-son groove 9.
Described anchoring hook 8 is fixed by welding and cylindrical shell 11.
Carefully do not state part in above content for prior art, therefore do not run business into particular one and state.
