Description

Technical Field

[0001] The utility model relates to the technical field of regenerative furnaces, in particular to an energy-saving regenerative furnace. Background Art

[0002] A regenerative furnace is an industrial furnace using the regenerative principle, mainly used to improve the energy utilization efficiency. It stores heat and releases it when needed to achieve the effective utilization of heat energy. At the same time, industries with large-scale stable heat sources require regenerative furnaces to collect heat for operation and production. When heat is needed, the regenerative furnace releases the stored heat to heat the working area, thereby reducing energy consumption and fluctuations and improving production efficiency.

[0003] For this, Chinese Patent Publication No. CN220648346U discloses an energy-saving regenerative furnace. As can be seen from the above solution, a filter screen is provided in the smoke outlet pipe, which can filter out particulate matter in the flue gas and reduce the risk of pollution. In addition, a structure in which a clamping groove and a raised block are provided at the top of the smoke outlet pipe can conveniently adjust the clamping of the filter screen. The detachable structure makes the filter screen easier to replace and clean. Moreover, an upper magnetic strip is designed at the top end of the smoke outlet pipe and a lower magnetic strip is designed on the outer side of the filter screen. The magnetic strips can adsorb up and down, so that the sliding connection between the filter screen and the smoke outlet pipe is more fixed. However, there are still some problems in the specific use of the existing energy-saving regenerative furnace: when the regenerative furnace is used to accumulate heat energy for industrial production, some heat is consumed while the heat is discharged. The influence of the flow rate on heat transfer is mainly reflected in convection and heat transfer efficiency. Too high a flow rate may lead to unnecessary heat loss, while too low a flow rate may lead to ineffective heat transfer, affecting the heat supply to the equipment. The increase in heat loss means more energy input to make up for the insufficient heat, further increasing the operating cost. Summary of the Utility Model

[0004] The utility model provides an energy-saving regenerative furnace to solve the problems raised in the above background art.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] An energy-saving regenerative furnace, comprising a regenerative furnace housing, wherein a heat fluid adjustment mechanism is arranged in the middle of the inner wall of the regenerative furnace housing, and a discharge pipe is fixedly connected to the upper end of the heat fluid adjustment mechanism;

[0007] The heat fluid adjustment mechanism includes an inverted conical guide plate, which is fixed at one end of the discharge pipe.

One end of the deflector is rotatably connected with an auxiliary fixing block through a set rotating shaft. One end of the auxiliary fixing block is fixedly connected with an electric push rod, and the upper end of the electric push rod is fixedly connected with a top support plate.

[0008] As a further improvement of this technical solution: A suction pipe is fixedly connected to the bottom of one side of the regenerative furnace shell through a through hole.

[0012] As a further improvement of this technical solution: Support bases are commonly fixedly connected to the bottoms of both side surfaces of the regenerative furnace shell, and auxiliary support jacks are fixedly connected to both side surfaces of the support bases.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

In the following paragraphs, the present utility model is described more specifically by way of example with reference to the accompanying drawings.

It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0025] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, an energy-saving regenerative furnace includes a regenerative furnace housing 1. A heat fluid adjustment mechanism 2 is provided in the middle of the inner wall of the regenerative furnace housing 1, and a discharge pipe 3 is fixedly connected to the upper end of the heat fluid adjustment mechanism 2;

[0026] The heat fluid adjustment mechanism 2 includes an inverted conical guide plate 201. The inverted conical guide plate 201 is fixed at one end of the discharge pipe 3. Both sides of the lower end of the inverted conical guide plate 201 are fixedly connected with connecting support plates 202. One end of the connecting support plate 202 is rotatably connected with a deflector plate 203 through a set rotating shaft. One end of the deflector plate 203 is rotatably connected with an auxiliary fixing block 204 through a set rotating shaft. One end of the auxiliary fixing block 204 is fixedly connected with an electric push rod 205. The upper end of the electric push rod 205 is fixedly connected with a top support plate 206. Through the settings of structures such as the heat fluid adjustment mechanism 2 and the discharge pipe 3, after the hot air is injected into the inner part of the regenerative furnace shell 1, the inclination angle of the deflector plate 203 is controlled so that the distance between the two deflector plates 203 is the distance through which the hot air passes, in order to achieve the flow rate when the heat passes. An appropriate flow rate ensures sufficient contact time between the fluid and the heat exchange surface, thereby improving the heat exchange efficiency and reducing heat loss.

[0027] Please refer to Figure 2 、 4 On the bottom of one side of the regenerative furnace shell 1, a suction pipe 4 is fixedly connected through a through hole opened. The other end of the discharge pipe 3 is fixedly connected with a water storage tank 5. One side of the surface of the water storage tank 5 is provided with a valve 6. The valve 6 controls the opening and closing of the heat discharged into the water storage tank 5, so that after the heat is recovered into the water storage tank 5, a certain amount of hot air is stored and slowly cooled to a suitable temperature for people to use for cleaning.

[0028] Please refer to Figure 4 On one side of the inner bottom wall of the water storage tank 5, a partition plate 7 is fixedly connected. One side surface of the partition plate 7 is fixedly connected with a water pump 8. The input end of the water pump 8 is fixedly connected with a suction pipe 9. The output end of the water pump 8 is fixedly connected with a discharge pipe 10. The partition plate 7 separates the internal space of the water storage tank 5, and the water pump 8 is deployed to the area without water to avoid the water inlet short - circuit fault of the water pump 8.

[0029] Please refer to Figures 1 to 2 In the middle of the surface of the discharge pipe 10, it is fixedly connected with the top of one side surface of the water storage tank 5 through a through hole opened. The lower end of the water storage tank 5 is fixedly connected with a support plate 11. The support plate 11 effectively supports the bottom of the water storage tank 5. At the same time, the gap between the discharge pipe 10 and the water storage tank 5 is filled with polyurethane foam, which has good heat insulation and sound insulation properties and is widely used in building insulation and refrigeration equipment.

[0030] Please refer to Figures 1 to 2, one end of the supporting slab 11 is fixedly connected to the middle of the other side of the regenerative furnace shell 1. The middle of the upper end of the regenerative furnace shell 1 is fixedly connected to one side near the middle of the surface of the discharge pipe 3 through a through hole. Polyurethane foam is filled at the position where the regenerative furnace shell 1 contacts the discharge pipe 3 to prevent hot air from leaking from the regenerative furnace shell 1. At the same time, heat insulation material, namely aluminum silicate wool, is provided on the surface of the discharge pipe 3, which has high temperature resistance and excellent heat insulation performance and is suitable for high temperature environments.

[0031] Please refer to Figures 1 to 2 , the bottoms of both sides of the regenerative furnace shell 1 are fixedly connected together with a supporting base 12. Auxiliary supporting jacks 13 are fixedly connected to both sides of the supporting base 12. While the supporting base 12 is used to support the bottom installation of the regenerative furnace shell 1, at the same time, the auxiliary supporting jacks 13 are arranged on both sides of the supporting base 12 to increase the supporting stability of the supporting base 12 for the regenerative furnace shell 1.

[0032] The working principle of the present utility model is:

[0033] After hot air enters the regenerative furnace shell 1 through the suction pipe 4, the corresponding electric push rod 205 is driven to expand and contract. The auxiliary fixing block 204 is driven to rise or fall by the thrust of the electric push rod 205. The auxiliary fixing block 204 thus drives the deflector plate 203 to perform corresponding flipping at one end of the connecting support plate 202. The size of the air outlet formed between the two deflector plates 203 is thus effectively controlled, which is convenient for controlling the hot air flow through the inverted conical guide plate 201, maintaining sufficient heat energy. At the same time, after the heat is discharged into the water storage tank 5, it is pumped out by the water pump 8 into the discharge pipe 10 for hot water use.

[0034] The above is only the preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to the description shown in the accompanying drawings of the specification and the above description; however, any slight changes, modifications and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any equivalent changes, modifications and variations made to the above embodiments based on the essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
