Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heating furnaces, and particularly relates to a structure of a regenerative heating furnace. Background Technique
[0002] A regenerative heating furnace is a heating device that uses regenerative materials to store thermal energy. A regenerative heating furnace is a device often used in production and processing for the purpose of heating. A regenerative heating furnace can be divided into air preheating and gas preheating according to the heat medium, and regenerative heating furnaces are also widely used in steel rolling production.
[0003] When the regenerative furnace is heating, outside air needs to enter the regenerative heating furnace to support the combustion and heat exchange processes. Specifically: the outside air provides oxygen to support the combustion of fuel and generate heat. However, the inlet design of existing heating furnaces usually does not consider the flammable substances that may be contained in the outside air. These flammable substances may come from the surrounding environment, such as volatile organic compounds (VOCs), dust or gases, and these substances may pose safety hazards under high-temperature conditions. In addition, the current inlet of the heating furnace lacks an effective air treatment device and cannot filter or purify the air entering the furnace. This leads to instability in the combustion process inside the furnace, may affect the thermal efficiency, and increases the risk of equipment failure.
[0004] The purpose of the present utility model is to provide a structure of a regenerative heating furnace to solve the problems raised in the background technique. Content of the Utility Model
[0005] The purpose of the present utility model is to provide a structure of a regenerative heating furnace to solve the problems raised in the background technique.

[0007] The purification component includes a purification box body connected to the other end of the air outlet pipe. First mounting plates are symmetrically installed inside the purification box body. Connecting columns are symmetrically connected up and down between the two first mounting plates. A second mounting plate is arranged outside the connecting columns, and a filtering component for filtering flammable impurities in the air is arranged inside the second mounting plate.
[0008] Further, the filtering component includes mounting grooves arranged on the second mounting plate. Limiting grooves are symmetrically opened up and down inside the mounting grooves. A filter plate is slidably connected to the mounting grooves, and a filter screen is arranged on the filter plate.
[0009] Further, a first spring for buffering the second mounting plate is sleeved outside the connecting column. One end of the first spring is connected to the first mounting plate, and the other end is connected to the second mounting plate.
[0010] Further, four groups of second springs are symmetrically arranged on both sides of the filter plate. One end of the second spring is connected inside the filter plate, and the other end is connected with a limiting ball adapted to the shape of the limiting groove.
[0011] Further, an air inlet pipe is arranged on one side of the purification box body. A first air extraction valve is installed outside the air inlet pipe, and a second air extraction valve is installed outside the air outlet pipe.
[0012] Further, a support column is fixedly installed at the inner bottom of the purification box body. A bent heating pipe for heating the filtered air is fixedly installed on the support column. A controller is arranged outside the purification box body, and the controller is electrically connected to the heating pipe.
[0013] Further, a combustion furnace is arranged on the heating furnace body, and a plurality of heat storage sheets are arranged on one side of the combustion furnace.
[0014] Compared with the prior art, the present utility model has the following beneficial effects:
[0015] By arranging a purification box body on one side of the heating furnace body in the present utility model, after the first air extraction valve sucks air into the purification box body, impurities contained therein are adsorbed by the filtering assembly, and then it is sucked into the heating furnace body through the second air extraction valve to provide oxygen for combustion.

One side of the combustion furnace 17 is provided with a plurality of regenerative sheets 18. One end of an air outlet duct 7 is connected to one side of the heating furnace body 1, and the other end of the air outlet duct 7 is connected to a purification assembly for purifying the air entering the heating furnace body 17.
[0029] The purification component includes a purification box body 2 connected to the other end of the air outlet duct 7. First mounting plates 9 are symmetrically installed inside the purification box body 2. Connecting columns 13 are symmetrically connected up and down between the two first mounting plates 9. A second mounting plate 11 is arranged outside the connecting columns 13. A filtering component for filtering flammable impurities in the air is arranged inside the second mounting plate 11. The function of arranging the filtering component here is to facilitate the filtering of flammable substances in the air and provide a safe working environment for the heating furnace body 1.
[0030] The filtering component includes a mounting groove 20 arranged on the second mounting plate 11. Limiting grooves 12 are symmetrically opened up and down inside the mounting groove 20. A filter plate 8 is slidably connected to the mounting groove 20. A filter net is arranged on the filter plate 8. A first spring 14 for buffering the second mounting plate 11 is sleeved outside the connecting column 13. The function of arranging the first spring 14 here is to facilitate reducing the impact force of the air on the second mounting plate 11 and protecting the filter plate 8. One end of the first spring 14 is connected to the first mounting plate 9, and the other end is connected to the second mounting plate 11. Four groups of second springs 16 are symmetrically arranged on both sides of the filter plate 8. One end of the second spring 16 is connected inside the filter plate 8, and the other end is connected to a limiting ball 15 adapted to the shape of the limiting groove 12. The function of arranging the limiting ball 15 adapted to the shape of the limiting groove 12 here is to facilitate the limiting of the filter plate 8.
[0031] An air inlet duct 3 is arranged on one side of the purification box body 2. A first air extraction valve 4 is installed outside the air inlet duct 3. A second air extraction valve is installed outside the air outlet duct 7. A support column 19 is fixedly installed at the bottom inside the purification box body 2. A bent heating duct 10 for heating the filtered air is fixedly installed on the support column 19. The function of arranging the heating duct 10 here is to heat the filtered air, which can reduce the loss of heat energy in the heating furnace body 1. A controller 5 is arranged outside the purification box body 2, and the controller 5 is electrically connected to the heating duct 10.
[0032] The connection methods and temperature control methods of the first air extraction valve 4, the second air extraction valve 6, the controller 5 and the heating duct 10 all belong to the prior art.

The provision of power also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control method and circuit connection of the present utility model will not be explained in detail.
[0033] Working principle: The first air extraction valve 4 sucks external air into the purification box body 2 through the air inlet pipe 3. The air passes through the filter plate 8. The first spring 14 arranged outside the connecting column 13 will buffer the impact force generated by the air, thereby protecting the filter plate 8 and extending the service life of the filter plate 8. After passing through the filter plate 8, it is heated through the heating pipe 10, and then the air is sucked into the heating furnace body 1 through the second air extraction valve 6 through the air outlet pipe 7 to provide oxygen for the combustion of the combustion furnace 17. The heat storage fins 18 store the generated heat energy;
[0034] When it is necessary to replace or clean the filter plate 8, open the door of the purification box body 2 and pull the filter plate 8 outwards. The limit ball 15 leaves the limit groove 12 in the installation groove 20, and the limit ball 15 moves into the filter plate 8, so that the second spring 16 is compressed. When the filter plate 8 is completely pulled out of the second mounting plate 11, the second spring 16 resumes deformation and pushes the limit ball 15 out.
