Description

Technical Field

[0001] The utility model relates to the technical field of pelletizing sintering, in particular to a pelletizing sintering furnace. Background Art

[0002] China's steel industry has developed rapidly. China has ranked first in the world in crude steel output for 13 consecutive years. With the rapid growth of China's national economy, the steel industry will continue to develop for a long period of time. However, since a large amount of fuel and ore will be consumed in the process of steel smelting and production, a large amount of atmospheric pollutants will be generated, and the load on the environment will continue to increase. This has become one of the bottlenecks restricting the sustainable development of the steel industry. At present, the emission of atmospheric pollutants such as SO2 in the steel industry has accounted for about 11% of the emissions of all industries in the country, second only to the power industry. Among them, the dust, SO2, CO2 and other pollution emissions generated by the pellet sintering process account for 40% to 60% of the annual emissions of the steel industry. Therefore, the emission control of pollutants such as SO2 from the flue gas of sintering pellets and metallurgical furnaces will be of great significance to the sustainable development of the metallurgical industry and the improvement of the ecological environment. However, the existing pellet sintering furnaces still contain a small amount of dust and harmful substances in the smoke after the smoke treatment. When the dust and harmful substances are discharged into the atmosphere, the environmental pollution increases. Utility Model Content

[0003] The purpose of the utility model is to provide a pelletizing sintering furnace to address the deficiencies of the prior art, so as to solve the problem proposed in the above background technology that the existing pelletizing sintering furnace still contains a small amount of dust and harmful substances in the smoke emitted after the smoke is treated, and when the dust and harmful substances are discharged into the atmosphere, environmental pollution is increased.

[0004] To achieve the above object, the utility model provides the following technical solution: a pelletizing sintering furnace, comprising a furnace structure, a filtering structure is fixed on one side of the furnace structure, and a spray collection structure is fixed inside the filtering structure;

[0005] The kiln structure includes a pelletizing sintering kiln body as a main body, and a flange connecting pipe is installed on one side of the pelletizing sintering kiln body through a smoke exhaust pipe, and a high-frequency fan is installed at the bottom of the flange connecting pipe. The bottom of the high-frequency fan is embedded and connected with the filtering structure through another flange connecting pipe.

[0006] By adopting the above technical solution, the high-frequency fan is provided to achieve extraction and transportation.

[0007] Preferably, the filtering structure comprises a filtering box with a through-hole partition inside, and a bearing seat is fixed inside the filtering box, and a spring clip is fixed inside the bearing seat.

[0008] By adopting the above technical solution, a rotating matching connection is achieved through the provided bearing seat.

[0009] Preferably, a connecting shaft is rotatably mounted inside the bearing seat, and a clamping seat that contacts and limits the spring clamp is welded and fixed on the surface of the connecting shaft, and a connecting disk is fixed at one end of the connecting shaft.

[0010] By adopting the above technical solution, the spring clip is provided to achieve unidirectional elastic adjustment.

[0011] Preferably, a through-hole arc plate with a receiving slot is fixed on the surface of the connection plate, and an activated carbon filter is mounted on the through-hole arc plate through the internal engagement of the receiving slot, and an air flow sensor module is fixed on one side of the filter box.

[0012] By adopting the above technical solution, the provided storage slot can achieve matching card-engaging storage.

[0013] Preferably, the spray collection structure includes a spray pipe head fixed to one side of the through-hole partition, and the spray pipe head is installed and connected to the high-pressure water pump through a connecting pipe, and the high-pressure water pump is installed inside the water tank through a filter cover.

[0014] By adopting the above technical solution, the filter screen is arranged to achieve interception and filtration.

[0015] Preferably, a connection cover is mounted on the water tank, and the connection cover is mounted at the lower part of the filter box, and the filter box is connected to the water tank through the connection cover.

[0016] By adopting the above technical solution, the connecting cover is provided to achieve flow guidance and transportation.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the pelletizing sintering furnace,

[0018] (1) This case sets up a filtering structure to solve the problem that the smoke emitted by the existing pelletizing sintering furnace still contains a small amount of dust and harmful substances after the smoke is treated. When the dust and harmful substances are discharged into the atmosphere, environmental pollution is increased. When the smoke to be discharged is discharged through the smoke exhaust pipe, the smoke is transported to the inside of the filter box by a high-frequency fan. The smoke entering the filter box is filtered by activated carbon for adsorption and filtration. The smoke after adsorption and filtration is transported to the other side of the filter box for spraying again and then discharged from the filter box.

[0019] (2) The spring card, the card seat and the through-hole arc plate are arranged in the filtering structure, so as to solve the problem that the activated carbon filter needs to be frequently replaced after long-term use. When a single activated carbon filter has been used for a long time, the permeability of the single activated carbon filter is poor. At this time, when the smoke pushes the connecting shaft to rotate, the card seat squeezes the spring card, and the spring card limits the card seat to achieve the effect of replacing the activated carbon filter for filtering, adsorption and purification;

[0020] (3) By setting up a spray collection structure, the problem of a small amount of harmful substances still being contained in the smoke is solved. When the smoke is purified and transported to the other side of the filter box, the high-pressure water pump works to spray the medicine inside the filter box to spray the smoke, so that the sprayed medicine can neutralize the harmful substances in the smoke and purify it again.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: a pelletizing sintering furnace, such as Figure 1 and Figure 2 As shown, a furnace structure 1 is included, and the furnace structure 1 includes a pelletizing sintering furnace body 101 as a main body, and a flange connecting pipe 103 is installed on one side of the pelletizing sintering furnace body 101 through a smoke exhaust pipe 102, and a high-frequency fan 104 is installed at the bottom of the flange connecting pipe 103, and the bottom of the high-frequency fan 104 is embedded and connected with the filtering structure 2 through another flange connecting pipe 103.

[0030] In the above scheme, when the pelletizing sintering furnace body 101 is working, the high-frequency fan 104 works synchronously. At this time, the high-frequency fan 104 transports the smoke through the flange connection pipe 103 to the inside of the filter box 201 for purification spraying treatment.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, a filter structure 2 is fixed on one side of the kiln structure 1, and the filter structure 2 includes a filter box 201 with a through-hole partition 202 inside, and a bearing seat 203 is fixed inside the filter box 201, and a spring clip 204 is fixed inside the bearing seat 203, wherein a group of spring clips 204 are provided, and the set of spring clips 204 are used to achieve a rotational engagement and limiting effect on the connecting shaft 205, which can prevent the connecting shaft 205 from rotating freely and also prevent the used activated carbon filter 2010 from being in the initial position and unable to filter and purify the smoke.

[0032] In the above scheme, a connecting shaft 205 is rotatably installed inside the bearing seat 203, and a clamping seat 206 that contacts and limits the spring clamp 204 is welded and fixed on the surface of the connecting shaft 205, and a connecting disk 207 is fixed at one end of the connecting shaft 205.

[0033] Furthermore, the above scheme has a through-hole arc plate 208 with a storage slot 209 fixed on the surface of the connecting plate 207, and the through-hole arc plate 208 is mounted with an activated carbon filter 2010 through the internal engagement of the storage slot 209, and an air flow sensing module is fixed on one side of the filter box 201, wherein the air flow sensing module is utilized to detect the air flow of the transported smoke, and when the smoke air flow is reduced, the operator can replace all the activated carbon filters 2010.

[0034] In the above scheme, when smoke enters the filter box 201, it is filtered and purified by the activated carbon filter 2010. After the activated carbon filter 2010 has been used for a long time, the activated carbon filter 2010 is prone to clogging. At this time, the smoke pushes the activated carbon filter 2010 and the through-hole arc plate 208 to rotate, which drives the connecting shaft 205 to rotate. When the connecting shaft 205 is rotated under force, it drives the holder 206, the spring holder 204 and the bearing seat 203 to rotate relative to each other. At this time, a new activated carbon filter 2010 is replaced for filtering and purification.

[0035] like Figure 6 As shown, a spray collection structure 3 is fixed inside the filter structure 2, and the spray collection structure 3 includes a spray pipe head 301 fixed on one side of the through-hole partition 202, and the spray pipe head 301 is installed and connected to the high-pressure water pump 303 through a connecting pipe 302, and the high-pressure water pump 303 is installed inside the water tank 305 through a filter cover 304.

[0036] Furthermore, in the above solution, a connection cover 306 is mounted on the water tank 305 , and the connection cover 306 is mounted at the bottom of the filter box 201 , and the filter box 201 is connected to the water tank 305 through the connection cover 306 .

[0037] In the above scheme, when the filtered and purified smoke enters the other side of the filter box 201 through the through-hole partition 202, the high-pressure water pump 303 sprays the medicine through the spray pipe head 301 to neutralize the harmful substances in the smoke, and the sprayed medicine flows back to the water tank 305 through the connecting cover 306 for recycling.
