[0003] In the prior art, a large tank reduction furnace is often supported by a steel frame. Ceramic fiber paper is placed on the top of the large tank reduction furnace, and refractory mortar is applied to the ceramic fiber paper for combustion. The refractory mortar insulates the top of the large tank reduction furnace to avoid heat loss of the large tank reduction furnace, thereby achieving the effect of heat preservation and energy saving of the large tank reduction furnace.
[0004] However, after being heated for a long time, the refractory mortar will become powdery, which causes the heat insulation effect of the refractory mortar to deteriorate, resulting in more heat loss from the top of the large tank reduction furnace and unable to achieve effective heat preservation and energy saving of the large tank reduction furnace. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a heat preservation and energy saving device for a large tank reduction furnace to solve the technical problem that in the prior art, after being heated for a long time, the refractory mortar will become powdery, which causes the heat insulation effect of the refractory mortar to deteriorate, resulting in more heat loss from the top of the large tank reduction furnace and unable to achieve effective heat preservation and energy saving of the large tank reduction furnace.
[0006] The technical problem to be solved by the utility model can be realized by the following technical solutions:
[0007] A heat preservation and energy saving device for a large tank reduction furnace, comprising:
[0008] A steel frame, inside which a large tank reduction furnace is provided;
[0009] A first precast block, which is in abutting connection with the top end of the large tank reduction furnace. A second precast block is connected in cooperation with the side end of the first precast block. The internal structures of the first precast block and the second precast block are the same, and the second precast block is in abutting connection with the top end of the large tank reduction furnace;
[0010] An iron plate, which is located at the top of the first precast block and is respectively connected in cooperation with the first precast block and the second precast block.

[0012] As a further solution of the utility model: several of the placement grooves are respectively located around the inner wall of the steel frame, and several placement grooves are respectively in abutting connection with the bottoms of the first precast block and the second precast block.
[0013] As a further solution of the utility model: a storage groove is formed inside the first precast block, and several limiting grooves are longitudinally formed at one end of the first precast block close to the second precast block. Heat insulation cotton is arranged in the storage groove, and the heat insulation cotton is in abutting connection with the inner wall of the storage groove.
[0014] As a further solution of the utility model: several limiting plates are respectively fixedly connected longitudinally at one end of the second precast block close to the first precast block, and the limiting plates are matched with the limiting grooves.

[0016] The beneficial effects of the utility model:
[0017] 1. When the large tank reduction furnace is placed in the steel frame, in order to avoid the phenomenon that the heat insulation effect of the refractory mortar becomes poor, the refractory mortar is changed to the first precast block and the second precast block for heat preservation treatment of the large tank reduction furnace. The first precast block and the second precast block can be made of heat insulation materials in the prior art. The first precast block and the second precast block are respectively placed on the top of the large tank reduction furnace, and the first precast block and the second precast block are cooperatively abutted. Compared with the refractory mortar that becomes powdery after being heated, the first precast block and the second precast block will not change in shape during long-term use, ensuring the stability of heat preservation for the large tank reduction furnace, thereby achieving the energy-saving effect of the large tank reduction furnace. The iron plate is installed at the tops of the first precast block and the second precast block, and the iron plate fixes the first precast block and the second precast block together, thereby avoiding gaps between the first precast block and the second precast block and affecting the heat preservation effect of the first precast block and the second precast block on the large tank reduction furnace.
[0018] 2. After the large tank reduction furnace runs for a long time, the large tank reduction furnace needs to be taken out of the steel frame to clean the sundries inside. The staff needs to clean the refractory mortar, and improper cleaning will cause the powdery refractory mortar to fall into the gap between the large tank reduction furnace and the steel frame. Compared with the refractory mortar in the prior art, the staff only needs to control the iron plate to directly take out the first precast block and the second precast block, and then take out the large tank reduction furnace from the steel frame.

Specific embodiments
[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0028] As Figures 1-6 shown, a heat preservation and energy-saving device for a large tank reduction furnace includes: a steel frame 1, a first precast block 6 and an iron plate 2,
[0029] Inside the steel frame 1 is provided with a large tank reduction furnace 4. The large tank reduction furnace 4 is placed inside the steel frame 1 for operation. In the prior art, multiple steel frames 1 are arranged together, so as to facilitate the steel frame 1 to be used for placing multiple large tank reduction furnaces 4 for operation;
[0030] The first precast block 6 abuts and connects with the top of the large tank reduction furnace 4. The side end of the first precast block 6 is fitted and connected with the second precast block 12. The internal structures of the first precast block 6 and the second precast block 12 are the same. The second precast block 12 abuts and connects with the top of the large tank reduction furnace 4. The iron plate 2 is located at the top of the first precast block 6. The iron plate 2 is respectively fitted and connected with the first precast block 6 and the second precast block 12. When the large tank reduction furnace 4 is placed in the steel frame 1, in order to avoid the phenomenon that the heat insulation effect of the refractory mortar becomes poor, the refractory mortar is changed to the first precast block 6 and the second precast block 12 to carry out heat preservation treatment on the large tank reduction furnace 4. The first precast block 6 and the second precast block 12 can be made of heat insulation materials in the prior art. The first precast block 6 and the second precast block 12 are respectively placed on the top of the large tank reduction furnace 4. The first precast block 6 and the second precast block 12 are abutted and held in cooperation. Compared with the refractory mortar which becomes powdery after being heated, the first precast block 6 and the second precast block 12 will not change in shape during long-term use, ensuring the stability of heat preservation for the large tank reduction furnace 4, thereby achieving the energy-saving effect of the large tank reduction furnace 4. The iron plate 2 is installed on the top of the first precast block 6 and the second precast block 12. The iron plate 2 fixes the first precast block 6 and the second precast block 12 together, thereby avoiding gaps between the first precast block 6 and the second precast block 12, which affects the heat preservation effect of the first precast block 6 and the second precast block 12 on the large tank reduction furnace 4. It should be noted that when the large tank reduction furnace 4 operates for a long time, the large tank reduction furnace 4 needs to be taken out of the steel frame 1 to clean the internal sundries. The staff needs to clean the refractory mortar, and improper cleaning will cause the powdery refractory mortar to fall into the gap between the large tank reduction furnace 4 and the steel frame 1. Compared with the refractory mortar in the prior art, the staff only needs to control the iron plate 2 to directly take out the first precast block 6 and the second precast block 12, and then take out the large tank reduction furnace 4 from the steel frame 1.
[0031] In some specific implementation schemes, a placement groove 13 is opened inside the steel frame 1. A plurality of support plates 14 are fixedly connected to the inner wall of the steel frame 1. The large tank reduction furnace 4 is arranged in the placement groove 13. The first precast block 6 and the second precast block 12 respectively abut and connect with the inner wall of the steel frame 1. A plurality of placement grooves 13 are respectively located around the inner wall of the steel frame 1. A plurality of placement grooves 13 respectively abut and connect with the bottom ends of the first precast block 6 and the second precast block 12. When the large tank reduction furnace 4 is installed at the placement groove 13 inside the steel frame 1, there will be a gap between the large tank reduction furnace 4 and the inner wall of the steel frame 1. In order to avoid the heat of the large tank reduction furnace 4 flowing out from the gap, the first precast block 6 and the second precast block 12 are installed along the inner wall of the steel frame 1. The first precast block 6 and the second precast block 12 block the gap, thereby achieving the effect of fully heat preserving the large tank reduction furnace 4. Among them, the support plate 14 abuts against the first precast block 6 and the second precast block 12 to avoid the phenomenon of overturning caused by the lack of support around the first precast block 6 and the second precast block 12.
[0032] In some specific embodiments, a storage groove 7 is formed inside the first precast block 6. A plurality of limiting grooves 10 are longitudinally formed at one end of the first precast block 6 close to the second precast block 12. An insulating cotton 8 is arranged in the storage groove 7, and the insulating cotton 8 is in abutting connection with the inner wall of the storage groove 7. A plurality of limiting plates 11 are respectively fixedly connected longitudinally at one end of the second precast block 12 close to the first precast block 6. The limiting plates 11 cooperate with the limiting grooves 10. In order to reduce the mass of the first precast block 6 and the second precast block 12, storage grooves 7 are formed inside both the first precast block 6 and the second precast block 12. The insulating cotton 8 has the effect of heat insulation and heat preservation. The insulating cotton 8 is filled in the storage groove 7, and then the first precast block 6 and the second precast block 12 are precast. On the premise of not affecting the heat preservation of the first precast block 6 and the second precast block 12, the mass of the first precast block 6 and the second precast block 12 is reduced, thereby reducing the workload of the staff in installing and transporting the first precast block 6 and the second precast block 12. Among them, when the second precast block 12 and the first precast block 6 are installed in cooperation, the limiting plate 11 slides along the inner wall of the limiting groove 10. When the limiting plate 11 and the limiting groove 10 are in abutting connection, the positioning connection between the limiting plate 11 and the limiting groove 10 avoids the phenomenon of dislocation between the second precast block 12 and the first precast block 6. At the same time, the limiting plate 11 plays a guiding role when the second precast block 12 is installed.
[0033] In some specific embodiments, handles 3 are respectively fixedly connected to both sides of the top of the iron plate 2. Threaded holes 9 penetrating the iron plate 2 are respectively formed at the tops of the first precast block 6 and the second precast block 12. A bolt 5 is threadedly connected in the threaded hole 9, and the bolt 5 is in abutting connection with the iron plate 2. When the iron plate 2 is installed at the tops of the first precast block 6 and the second precast block 12, the bolt 5 is threadedly connected in the threaded hole 9, and the bolt 5 fixes the iron plate 2 on the first precast block 6 and the second precast block 12. When the staff needs to take out the first precast block 6 and the second precast block 12, the staff controls the handle 3 to pull the iron plate 2 upward.
[0034] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
