The self-adjusting support comprises a rigid support connected with the reactor, and a support beam. The self-adjusting support is characterized in that a heat-insulating block and an angle adjusting mechanism are orderly connected between the rigid support and the support beam; the heat-insulating block is a steel case body and the middle part thereof is provided with a support rib plate; each side plate of the case body is provided with a plurality of convection circular holes; the angle adjusting mechanism comprises an upper seat board, a convex spherical middle plate and a lower seat board. The middle part of the upper surface of the lower seat board is a concave sphere forming a first sliding surface with the lower surface of the convex sphere of the convex spherical middle plate; the lower surface of upper seat board and the upper surface of the convex spherical middle plate form a second sliding surface. Compared with the prior art, the self-adjusting support can automatically adjust the contact angle between the rigid support and the support beam under the state of adding load and rising temperature, to maintain the original forced direction of the structure framework beam and improve the forced state of structure beam radically.
Description
Technical field
The utility model relates to the combined type self-regulated bearing of large-scale non-standard equipment, especially for the self-adjustable supporting seat of Benitration reactor.
Background technology
Along with deepening continuously of national requirements for environmental protection, further processing is all being done in each big thermal power plant to fume emission, to reduce the pollution to atmosphere.Wherein the nucleus equipment in the denitrating flue gas is a Benitration reactor.The running temperature of Benitration reactor is about 400 ℃, and its inside is equipped with a large amount of heavy catalyst modules, and the weight of these catalyst accounts for 40～50% of integral device.In the prior art, the weight of Benitration reactor integral device is that a plurality of rigid mounts 4 by reactor body support column 3 and periphery act on structural frames on setting a roof beam in place.When not adding catalyst load, rigid mount 4 bottom surfaces are that face contacts with brace summer 7 upper surfaces, and brace summer 7 vertical stressed P are referring to Fig. 6.When Benitration reactor moves, along with continuing to increase of catalyst module 1 load and improving constantly of running temperature, Benitration reactor body support column 3 bending moments then continue to increase, rigid mount 4 produces warpage with the distortion of reactor body support column 3, rigid mount 4 bottom surfaces and brace summer 7 upper surfaces form angle α, referring to Fig. 7.At this moment brace summer 7 not only will be accepted vertical force P1, and has increased a bigger horizontal thrust P2, makes brace summer 7 stressed unfavorable and produce because the radial displacement that the Benitration reactor thermal expansion brings, and directly affects the service life of equipment.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this utility model provides a kind of self-adjustable supporting seat that is used for Benitration reactor.It can be under the state that load loads and temperature raises the contact angle of adjusting rigid mount and brace summer automatically, to keep the structural frames former force direction that is subjected to of setting a roof beam in place, fundamentally improve the force-bearing situation of structural beams.
In order to reach the foregoing invention purpose, the technical solution of the utility model realizes as follows:
The self-adjustable supporting seat that is used for Benitration reactor, it comprises rigid mount and the brace summer that is connected with reactor.Its design feature is to be connected with heat insulation and angle adjusting mechanism between described rigid mount and the brace summer in turn.Heat insulation is the steel casing and is equipped with bearing rib in the centre, has a plurality of convection current circular holes on each side plate of casing.Angle adjusting mechanism comprises upper base plate, protruding spherical intermediate plate and following seat board.The centre of following seat board upper surface is that the protruding ball lower surface of a spill sphere and protruding spherical intermediate plate forms first sliding surface, and upper base plate lower surface and protruding spherical intermediate plate upper surface form second sliding surface.
In above-mentioned self-adjustable supporting seat, be equipped with friction plate between described upper base plate lower surface and the protruding spherical intermediate plate upper surface, be lined with the arc friction plate between the protruding ball of protruding spherical intermediate plate lower surface and the following seat board.
In above-mentioned self-adjustable supporting seat, described each friction plate all adopts stainless steel material.
The utility model has been owing to adopted said structure, load increase and the process of temperature rising in self-adjustable supporting seat adjusting angle automatically, keep the former force direction that is subjected to of brace summer all the time, fundamentally improved the stressing conditions of brace summer.The radial displacement respective horizontal slidable adjustment that can bring according to the Benitration reactor thermal expansion of second sliding surface simultaneously.Heat insulation protection angle adjusting mechanism is not subjected to the influence of high running temperature in the reactor, and the corresponding rising of adopting the friction plate of stainless steel material to come adaptive temperature.The utlity model has simple in structure, self-regulated characteristics easily.The service life of using the utility model can improve equipment greatly.
Below in conjunction with the drawings and specific embodiments the utility model is described further.

The specific embodiment
Referring to Fig. 2 to Fig. 5, the utility model comprises rigid mount 4, heat insulation 5, angle adjusting mechanism 6 and the brace summer 7 that connects successively.Heat insulation 5 is equipped with bearing rib 9 for steel casing 8 and in the centre, has a plurality of convection current circular holes on each side plate of casing 8.Angle adjusting mechanism 6 comprises upper base plate 10, protruding spherical intermediate plate 12 and following seat board 11.The centre of following seat board 11 upper surfaces is that the protruding ball lower surface of a spill sphere and protruding spherical intermediate plate 12 forms first sliding surface 13, is lined with stainless steel arc friction plate between the protruding ball of protruding spherical intermediate plate 12 lower surfaces and the following seat board 11.Be equipped with the stainless steel friction plate between upper base plate 10 lower surfaces and protruding spherical intermediate plate 12 upper surfaces and form second sliding surface 14.
Referring to Fig. 1, the load of catalyst module 1 is to pass to reactor body support column 3 by catalyst brace summer 2, and reactor body support column 3 passes to reactor brace summer 7 with load by rigid mount 4, heat insulation 5 and angle adjusting mechanism 6 again.
Referring to Fig. 8, when catalyst load constantly increases and running temperature when constantly raising, the load that the angular adjustment assurance rigid mount 4 of first sliding surface 13 by angle adjusting mechanism 6 passes to brace summer 7 is always vertical load P.And the radial thermal expansion displacement of Benitration reactor can be regulated by second sliding surface, 14 levels of angle adjusting mechanism 6.
