Description

Technical Field

[0001] This utility model relates to the field of sintering machine technology, and more specifically, to a high-efficiency and energy-saving sintering machine. Background Technology

[0002] When a belt sintering machine is in use, air is drawn in through a flue so that the high temperature from the surface combustion can penetrate into the inner layer. However, this method of extraction also results in high exhaust air temperature and the air is prone to contain iron powder. If a cooling and filtration device is used, it will greatly increase energy consumption and investment. Therefore, a device with low energy consumption, simple structure and easy maintenance is needed to filter and cool the hot air discharged from the sintering machine.

[0003] Chinese Patent No. CN210718671U provides an energy-saving and emission-reduction device for sintering machines, including a hopper and a material distribution mechanism. The material distribution mechanism includes multiple staggered inverted V-shaped diversion plates, which are fixed to the inner wall of the hopper. Air inlets are fixed to the upper parts of both sides of the hopper, and these inlets are horizontally opposite each other and located above the diversion plates. A cover plate is provided at the top of the hopper, and a limiting part is fixedly connected to the upper side of the cover plate. A fixing seat is fixedly connected to the top of the hopper, and the cover plate engages with the inner wall of the fixing seat. This device effectively disperses the material, significantly increasing the contact area between the falling material and the air, preventing the material from concentrating inside the sintering machine and failing to burn completely, thus avoiding the generation of excessive polluting gases. Due to the good material dispersion, the exhaust gas after combustion contains fewer types of pollutants, simplifying treatment and reducing the treatment time and cost.

[0004] Currently, while existing high-efficiency and energy-saving sintering machines can achieve the purpose of dispersing and falling materials to completely burn polluting gases, they cannot cool and discharge the flue gas generated during the operation of the sintering machine in a low-energy manner, nor can they effectively filter the iron powder dust entrained in the hot gas. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency and energy-saving sintering machine, which aims to improve the problems that high-efficiency and energy-saving sintering machines cannot reduce flue gas temperature in a low-energy manner under normal circumstances and cannot filter iron powder entrained in the flue gas.

[0006] This utility model is implemented as follows: This utility model provides a high-efficiency and energy-saving sintering machine, including an exhaust structure and a filter structure disposed on one side of the exhaust structure. The exhaust structure includes a sintering component and an exhaust component, the exhaust component being fixed to the bottom of the sintering component. The filter structure includes a filter component and a water extraction component, the water extraction component being fixed to one side of the filter component. The filter component includes a baffle, the baffle being disposed on one side of the exhaust component. A drain pipe is fixed inside the baffle. A sealing plate is fixed inside the baffle. An air diffuser plate is fixed inside the baffle. A first partition is fixed inside the baffle. A water trough is opened at the top of the first partition. A sedimentation chamber is disposed inside the baffle. A second partition is fixed inside the baffle. A support plate is fixed to one side of the second partition. A water leakage hole is opened at the top of the support plate. A filter plate is disposed at the top of the support plate.

[0007] In one embodiment of this utility model, the sintered part includes a star wheel, a support rail is provided on one side of the star wheel, and a rotating wheel is rotatably connected inside the support rail.

[0008] In one embodiment of this utility model, a trolley plate is rotatably connected to one side of the rotating wheel, and a smoke pipe is provided inside the support rail frame.

[0009] In one embodiment of this utility model, the air extraction component includes a flue, the flue is fixed to the bottom of the flue pipe, a support frame is fixed inside the flue, and a bevel tooth is rotatably connected inside the support frame.

[0010] In one embodiment of this utility model, a fan blade is fixed to one end of the conical tooth, a heat insulation sleeve is fixed to the top of the flue, and a heat dissipation hole is provided on one side of the heat insulation sleeve.

[0011] In one embodiment of this utility model, a motor is fixed to the top of the heat insulation sleeve, and a bevel gear is fixed to the output shaft end of the motor.

[0012] In one embodiment of this utility model, the pumping component includes a support platform, which is fixed to one side of the enclosure. A water pump is fixed to the top of the support platform, and a motor is fixed to one side of the water pump.

[0013] In one embodiment of this utility model, a water pump is fixed to one side of the water pump and a drain pipe is fixed to the other side of the water pump.

[0014] Compared with existing technologies, this utility model provides a high-efficiency and energy-saving sintering machine through the above design. During use, the powerful suction capacity of the fan blades forces the flue gas into the water, forming bubbles. These bubbles are then broken into numerous smaller bubbles by the diffuser plate, thus cooling the gas. The water also adheres to the iron powder carried in the gas, completing the primary filtration. Subsequently, with the continuous water supply from the pump, the water flows from the water tank into the sedimentation chamber. The slow water flow in the sedimentation chamber further settles the iron powder adhering to the water during filtration. The water then flows onto the filter plate, further filtering the iron powder carried in the water. This flowing motion effectively cools the water, allowing it to continue operating and ensuring that the low-temperature water cools the high-temperature hot gas. Therefore, this method effectively achieves the purpose of cooling and filtration, and only requires power to the motor 233 throughout the entire process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0019] Please see Figure 1-4This utility model provides a technical solution: a high-efficiency and energy-saving sintering machine, including an exhaust structure 100 and a filter structure 200 disposed on one side of the exhaust structure 100. The exhaust structure 100 includes a sintering component 110 and an exhaust component 120, with the exhaust component 120 fixed to the bottom of the sintering component 110. The filter structure 200 includes a filter component 210 and a water extraction component 230, with the water extraction component 230 fixed to one side of the filter component 210. The filter component 210 includes a enclosure 211, which can be made of concrete. The enclosure 211 is disposed on one side of the exhaust component 120, and a drain pipe 212 is fixed inside the enclosure 211. The drain pipe 212 can discharge settled iron powder and also replace part of the water. A sealing plate 213 is fixed inside the enclosure 211. The sealing plate 213 prevents the gas in the bursting bubbles from scattering. A diffuser plate 214 is fixed inside the enclosure 211, which breaks large bubbles into many small bubbles. A partition 1 215 is fixed inside the enclosure 211, and a water channel 216 is provided on the top of the partition 1 215. A sedimentation chamber 217 is provided inside the enclosure 211, which settles iron particles entrained in the water by slowing down the water flow. A partition 218 is fixed inside the enclosure 211, and a support plate 219 is fixed on one side of the partition 218. A water leakage hole 220 is provided on the top of the support plate 219, which allows water to pass through the support plate 219. A filter plate 221 is provided on the top of the support plate 219, which can filter out extremely small iron particles in the water.

[0020] Please see Figure 1-3 The sintering component 110 includes a star wheel 111. The star wheel 111, support rail frame 112, rotating wheel 113, and trolley plate 114 are the main conveying components of the existing belt sintering machine. Their connection method is too cumbersome, so it will not be described in detail here. A support rail frame 112 is provided on one side of the star wheel 111. A rotating wheel 113 is rotatably connected inside the support rail frame 112. A trolley plate 114 is rotatably connected to one side of the rotating wheel 113. A smoke pipe 115 is provided inside the support rail frame 112. The exhaust component 120 includes a flue 121, which is fixed to the bottom of the smoke pipe 115. A support frame 122 is fixed inside the flue 121. The section of flue 121 where 22 is located has a circular aperture. Inside the support frame 122, there is a rotatable bevel gear 123. Bevel gear 123 and bevel gear 128 mesh with each other. A fan blade 124 is fixed to the end of bevel gear 123. A heat insulation sleeve 125 is fixed to the top of the flue 121. The heat insulation sleeve 125 prevents the high temperature of the flue 121 from being transferred to the motor 127. A heat dissipation hole 126 is opened on one side of the heat insulation sleeve 125. By setting the heat dissipation hole 126, the contact area between the heat insulation sleeve 125 and the air can be increased, thereby achieving rapid cooling. The top of the heat insulation sleeve 125 is fixed to the motor 127. Bevel gear 128 is fixed to the output shaft end of the motor 127.

[0021] Please see Figure 1 and Figure 4 The pumping unit 230 includes a support platform 231, which is fixed to one side of the enclosure 211. A water pump 232 is fixed to the top of the support platform 231. A motor 233 is fixed to one side of the water pump 232. A pumping pipe 234 is fixed to one side of the water pump 232. The pumping pipe 234 is connected to the cavity on the left side of the enclosure 211. A drain pipe 235 is fixed to one side of the water pump 232. The drain pipe 235 is connected to the cavity on the right side of the enclosure 211.

[0022] Specifically, the working principle of this high-efficiency and energy-saving sintering machine is as follows: During operation, when the sintered part 110 is running, the motor 127 is started, causing the motor 127 to drive the bevel gear 123 to rotate via the bevel gear 128. This allows the fan blade 124 to draw air through the flue 115 and deliver it into the enclosure 211. The external air then slowly permeates downwards through the surface of the iron powder layer, allowing the high temperature generated during baking of the iron powder layer to penetrate downwards. Simultaneously, the air enters the flue 121 through the flue 115 and finally, under air pressure, rushes into the water within the enclosure 211, forming large bubbles in the water. As these large bubbles rise, they are broken into numerous smaller bubbles by the air diffuser plate 214. The water temperature cools the smaller bubbles and removes impurities adhering to the surface. As the bubbles rise, they eventually burst open on the water surface. At this time, the sealing plate 213 will block the air from spreading after the bubbles burst, causing the iron powder to slowly sink and float. At the same time, the motor 233 drives the water pump 232 to run, so that the water cooled on the left side of the partition 218 is drawn into the right side of the partition 1 215. As a result, the water on the right side of the partition 1 215 flows out from the water channel 216 and into the sedimentation chamber 217 due to the rise in water level. At this time, the water level in the sedimentation chamber 217 will continue to rise, but the flow rate is slow, so the iron particles in the water can slowly sink. The water will also slowly flow onto the filter plate 221, and the filter plate 221 will further filter the water. The flow also serves to cool the water. Afterwards, the water seeps through the filter plate 221 and drips from the drain hole 220 into the cavity on the left side of the partition 2 218 for reuse.

[0023] It should be noted that the specific model specifications of Motor 127 and Motor 233 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0024] The power supply and operating principle of motor 127 and motor 233 are clear to those skilled in the art and will not be described in detail here.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
