Description

Technical Field

[0001] This utility model relates to the field of industrial furnaces, and in particular to an industrial furnace with a dust removal structure. Background Technology

[0002] An industrial furnace is a device used to melt metals and other materials. It mainly uses high-temperature heating to melt the materials inside into a liquid state.

[0003] Because the materials themselves may contain some impurities, these impurities will produce flue gas after heating, which is a gas containing dust. This flue gas not only affects the environment, but also endangers the health of the surrounding operators. Since the types of materials smelted each time are different, the types of impurities are also different, and the particle size of the dust produced is also different. Therefore, ordinary filtration methods such as filter screens are not enough to flexibly deal with dust of different particle sizes, resulting in the general dust removal effect of current industrial furnaces. Therefore, an industrial furnace with a dust removal structure is now being developed. Summary of the Invention

[0004] In order to overcome the shortcomings of the current industrial furnaces in terms of general dust removal effect, this utility model provides an industrial furnace with a dust removal structure.

[0005] The technical implementation scheme of this utility model is as follows: an industrial furnace with a dust removal structure includes a furnace, a cover plate placed on the top of the furnace, a connecting frame fixedly connected to the furnace, the connecting frame communicating with the furnace, a first connecting pipe detachably connected to the top of the connecting frame, the first connecting pipe communicating with the connecting frame, a fan fixedly connected to the bottom of the connecting frame, a discharge pipe snapped onto the top of the first connecting pipe, the discharge pipe communicating with the first connecting pipe, a first filter screen fixedly connected inside the discharge pipe, a filter plate fixedly connected inside the first connecting pipe, and a second connecting pipe fixedly connected to the connecting frame, an atomizing nozzle fixedly connected to the second connecting pipe, the atomizing nozzle being fixedly connected to the first connecting pipe, and a scraping component provided on the first filter screen.

[0006] Furthermore, it is particularly preferred that the scraping assembly includes a fan wheel, which is rotatably connected to the first filter screen, and a second filter screen is fixedly connected to the discharge pipe. Scrapers are fixedly connected to both sides of the fan wheel, and the tops of the scrapers contact the first filter screen and the second filter screen respectively.

[0007] Furthermore, it is particularly preferred that the industrial furnace with the dust removal structure also includes a screen frame that is slidably connected to the scraper.

[0008] Furthermore, it is particularly preferred that the industrial furnace with the dust removal structure also includes two containers, which are fixed to the discharge pipe. One container is higher than the second filter screen, and the other container is positioned between the first and second filter screens. The containers are fixed with micro-nozzles and are slidably connected to baffles.

[0009] Furthermore, it is particularly preferred that the industrial furnace with the dust removal structure also includes two tension ropes, which are respectively connected between the baffle and the adjacent container.

[0010] Furthermore, it is particularly preferred that the top of the scraper has a bevel.

[0011] This utility model has the following advantages:

[0012] This invention uses an atomizing nozzle to spray water onto flue gas, which mixes the smoke dust with the water, thereby increasing the particle size of the smoke dust and making it easier to filter out, thus achieving the purpose of dust removal.

[0013] This invention uses a scraper to remove the soot and dust adhering to the first and second filter screens, effectively cleaning them and preventing clogging that could affect gas discharge.

[0014] This invention utilizes chemical substances stored in a container to react chemically with harmful gases in flue gas, thereby neutralizing the harmful gases and purifying the flue gas. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Example 1: An industrial furnace with a dust removal structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the system includes a furnace 1, a cover plate 2 on top of the furnace 1, a connecting frame 3 fixed to the upper left of the furnace 1, the connecting frame 3 communicating with the furnace 1, a first connecting pipe 4 detachably connected to the top of the connecting frame 3, the first connecting pipe 4 communicating with the connecting frame 3, a fan 31 fixed to the bottom of the connecting frame 3, a discharge pipe 41 snapped onto the top of the first connecting pipe 4, the discharge pipe 41 communicating with the first connecting pipe 4, a first filter screen 6 fixed to the bottom inside the discharge pipe 41, a filter plate 5 fixed to the inside of the first connecting pipe 4, and a second connecting pipe 12 fixed to the left of the connecting frame 3, an atomizing nozzle 11 fixed to the right of the second connecting pipe 12, the atomizing nozzle 11 having its own water pump, the atomizing nozzle 11 fixed to the first connecting pipe 4, and the atomizing nozzle 11 having three spray outlets. A scraping component is provided on the first filter screen 6. The first filter screen 6, the second filter screen 7, and the filter plate 5 are all detachable.

[0028] like Figure 4 , Figure 5 and Figure 6As shown, the scraping assembly includes a blower 8, which is rotatably connected to the first filter screen 6. A second filter screen 7 is fixedly connected to the discharge pipe 41. Scrapers 9 are fixedly connected to both the upper and lower sides of the blower 8. The top of each scraper 9 is provided with an inclined surface. The top of the upper scraper 9 contacts the second filter screen 7, and the top of the lower scraper 9 contacts the first filter screen 6. A screen frame 10 is slidably connected to the lower side of each scraper 9.

[0029] When using this device, the cover plate 2 needs to be manually moved upwards first, then the material is put into the furnace 1. The cover plate 2 is then put back on the furnace 1. The furnace 1 is heated by an external device to melt the material. Since the material may generate flue gas after heating, and the top of the furnace 1 is closed by the cover plate 2, the flue gas will flow into the connecting frame 3. At this time, the blower 31 needs to be turned on, and the second connecting pipe 12 needs to be connected to the external water supply device. Then, the atomizing nozzle 11 needs to be turned on. Under the blowing of the blower 31, the flue gas will pass from bottom to top through the first connecting pipe 4. When the flue gas passes through the filter plate 5, It can perform preliminary filtration of smoke and dust in flue gas. As the pre-filtered flue gas moves upward again, the water pump built into the atomizing nozzle 11 can draw water from an external water supply device through the second connecting pipe 12, and the water will be sprayed out through the atomizing nozzle 11, thereby mixing the smoke and dust in the flue gas with the water, further increasing the particle size of the smoke and dust, making it easier for the smoke and dust to be filtered out by the first filter screen 6. Then, as the flue gas continues to move upward, the smoke and dust will be further filtered out by the second filter screen 7, thereby achieving the purpose of dust removal. At the same time, due to the wind force of the fan 31, the impeller 8 will rotate. Driven by the fan, scraper 9 rotates, scraping off the dust adhering to the first filter screen 6 and the second filter screen 7, causing the dust to fall into the screen frame 10. This cleans the first and second filter screens 6 and 7, preventing them from clogging and affecting gas discharge. Furthermore, the inclined surface on scraper 9 makes it easier to insert into the gap between the dust and the second filter screen 7, thus facilitating the scraping off of dust. After the material has melted and the generated fumes have been filtered and discharged through the discharge pipe 41, the fan 31 is turned off, and the external water supply device is disconnected from the second connection. Connect pipe 12, then open cover plate 2, remove the molten material, then disconnect discharge pipe 41 from first connecting pipe 4, disconnect first connecting pipe 4 from connecting frame 3, then move screen frame 10 so that screen frame 10 is separated from scraper 9, and clean screen frame 10, then clean first filter screen 6, second filter screen 7 and filter plate 5, and then reinstall each component back in its original position. By spraying water onto flue gas through atomizing nozzle 11, the dust in the flue gas can be mixed with water, thereby increasing the particle size of dust and making it easier to filter out dust, thereby achieving the purpose of dust removal.

[0030] Example 2: Based on Example 1, such as Figure 1 , Figure 8, Figure 9 and Figure 10 As shown, the industrial furnace with dust removal structure also includes two containers 13. Both containers 13 are fixed to the front of the discharge pipe 41. The height of one container 13 is higher than that of the second filter screen 7, and the height of the other container 13 is between the height of the first filter screen 6 and the second filter screen 7. The lower part of each container 13 is fixed with a micro nozzle 14, and the rear part of each container 13 is slidably connected with a baffle 15. The baffle 15 and the adjacent container 13 are connected with elastic ropes 16.

[0031] Since some materials easily produce harmful gases when heated, some chemical substances that can neutralize the harmful gases can be injected into container 13 in advance to treat the harmful gases, thereby purifying the flue gas. When discharging the flue gas, the micro nozzle 14 needs to be turned on. Under the blowing of the micro nozzle 14, the baffle 15 will move backward and the tension rope 16 will be stretched. At this time, the bottom of container 13 opens, the chemical substance falls and is blown towards the flue gas by the micro nozzle 14. This allows the harmful substances in the flue gas to react with the chemical substance, thereby neutralizing the harmful gases and purifying the flue gas. Since there are two containers 13, different types of harmful gases can be purified in stages. When the flue gas is discharged, the micro nozzle 14 is turned off, and under the action of the tension rope 16, the baffle 15 moves forward and resets.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
