Description

Technical Field

[0001] This utility model relates to the field of kiln heat recovery, specifically a flue gas waste heat recovery type kiln preheating device. Background Technology

[0002] A kiln is a piece of equipment made of refractory materials used to fire products. It is a key piece of equipment in the production of ceramics, glass, cement and other industries. The flue gas waste heat recovery type kiln preheating device usually uses the principle of heat exchange to transfer the heat in the high temperature flue gas discharged from the kiln to other media, such as air or water. These media absorb the heat and rise in temperature, and are then used to preheat the combustion air or workpiece, thereby improving the thermal efficiency of the kiln and reducing energy consumption.

[0003] However, most traditional flue gas waste heat recovery kiln preheating devices are not convenient for filtering impurities in the flue gas. They simply transport the high-temperature flue gas directly to the required equipment through pipelines. If the impurities and dust particles mixed in the flue gas are not filtered, they can easily adhere to the heat collection tubes and other waste heat recovery components, affecting their heat absorption capacity and reducing the efficiency of waste heat recovery. Utility Model Content

Impurities and dust particles easily adhere to waste heat recovery components such as heat collection tubes, affecting their heat absorption capacity and leading to problems such as reduced waste heat recovery efficiency. This utility model proposes a flue gas waste heat recovery kiln preheating device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a flue gas waste heat recovery kiln preheating device, including a kiln body, a door panel rotatably connected to one side of the kiln body, a heating pipe fixedly connected to the top of the kiln body, and a vibration mechanism provided at the other end of the heating pipe.

[0006] The vibration mechanism includes a top cover, the top of which is fixedly connected to one end of a heating pipe, a box body fixedly connected to the bottom of the top cover, a purification component being installed inside the box body, a collection box being inserted into the box body, a first positioning post being fixedly connected to the bottom of the box body, a base being installed at the bottom of the box body, a second positioning post being fixedly connected to the top of the base, springs being fixedly connected to the surfaces of the second positioning post and the first positioning post, and a heat exhaust pipe being fixedly connected to one side of the box body.

[0007] Preferably, a bearing is fixedly connected to the inner cavity of the base, a drive shaft is fixedly connected to the inner wall of the inner ring of the bearing, and a cam is fixedly connected to the surface of the drive shaft.

[0008] Preferably, an extension rod is fixedly connected to the bottom of the housing, and a roller is fixedly connected to the other end of the extension rod, with the surface of the roller conforming to the surface of the cam.

[0009] Preferably, a motor is fixedly installed on the inner side of the base, and the output end of the motor is fixedly connected to one end of the transmission shaft.

[0010] Preferably, the surface of the box is fixedly covered with an insulation layer, and an electric heating wire is fixedly connected to the inner wall of the insulation layer.

[0011] Preferably, the purification component includes a mounting frame, one side of which is fixedly connected to the inner wall of the housing, and a filter plate is fixedly connected to the inner wall of the mounting frame, wherein there are multiple filter plates.

[0012] Preferably, the surface of the spring is covered with sound-insulating cotton, one side of which is fixedly connected to the bottom of the housing, and the other side of which is fixedly connected to the top of the base.

[0013] The advantages of this utility model are:

[0014] In this invention, the base of the vibration mechanism plays a major supporting role, and the top cover can improve the emission efficiency of high-temperature flue gas. The high-temperature flue gas is filtered by the purification component to remove impurities and dust. The heat exhaust pipe can be connected to external equipment through a flange, and the filtered high-temperature flue gas is transported to the required equipment through the heat exhaust pipe. The motor can be regarded as the driving source of the vibration mechanism. The motor can drive the transmission shaft to rotate along the bearing. When the transmission shaft rotates, it drives the cam that is fixedly connected to the same axis to rotate. Since the box body is in contact with the cam through the extension rod and roller, when the cam rotates continuously, the protruding part can push the box body to vibrate continuously through the roller and extension rod. The spring between the box body and the base can improve the vibration effect, vibrating and removing the impurities and dust particles filtered in the purification component, ensuring the filtration efficiency of the purification component. The fallen impurities and dust particles are collected in the collection box. This solves the problems of most traditional flue gas waste heat recovery kiln preheating devices, which are not convenient for filtering impurities in flue gas, and impurities and dust particles are easy to adhere to the heat collection tube and other waste heat recovery components, affecting their heat absorption capacity and reducing waste heat recovery efficiency.

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

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a flue gas waste heat recovery type kiln preheating device. (Refer to...) Figures 1 to 4 A flue gas waste heat recovery type kiln preheating device includes a kiln body 1, a door panel 2 rotatably connected to one side of the kiln body 1, a heating pipe 3 fixedly connected to the top of the kiln body 1, and a vibration mechanism 4 provided at the other end of the heating pipe 3.

[0025] The vibration mechanism 4 includes a top cover 401, the top of which is fixedly connected to one end of the heating pipe 3. A housing 402 is fixedly connected to the bottom of the top cover 401. A purification component 5 is installed inside the housing 402. A collection box 403 is inserted into the housing 402. A first positioning post 404 is fixedly connected to the bottom of the housing 402. A base 405 is installed at the bottom of the housing 402. A second positioning post 406 is fixedly connected to the top of the base 405. Springs are fixedly connected to the surface of the second positioning post 406 and the surface of the first positioning post 404. 407. A heat exhaust pipe 408 is fixedly connected to one side of the housing 402. A bearing 6 is fixedly connected to the inner cavity of the base 405. A drive shaft 7 is fixedly connected to the inner wall of the inner ring of the bearing 6. A cam 8 is fixedly connected to the surface of the drive shaft 7. An extension rod 9 is fixedly connected to the bottom of the housing 402. A roller 10 is fixedly connected to the other end of the extension rod 9. The surface of the roller 10 is in contact with the surface of the cam 8. A motor 11 is fixedly installed inside the base 405. The output end of the motor 11 is fixedly connected to one end of the drive shaft 7. This flue gas waste heat recovery kiln preheating device... The high-temperature flue gas in the kiln body 1 is transported to the housing 402 in the vibration mechanism 4 via the heating pipe 3. The base 405 in the vibration mechanism 4 provides the main support, and the top cover 401 can improve the emission efficiency of the high-temperature flue gas. The high-temperature flue gas passes through the purification component 5 to filter impurities and dust in the gas. The heat exhaust pipe 408 can be connected to external equipment via a flange, and the filtered high-temperature flue gas is transported to the required equipment through the heat exhaust pipe 408. The motor 11 can be regarded as the driving source of the vibration mechanism 4. The motor 11 can drive the transmission shaft 7 along the bearing 6. As the drive shaft 7 rotates, it drives the coaxially fixed cam 8 to rotate as well. Since the housing 402 is in contact with the cam 8 through the extension rod 9 and the roller 10, the protruding part of the cam 8 can continuously vibrate the housing 402 through the roller 10 and the extension rod 9 when the cam 8 rotates continuously. The vibration effect can be improved by the spring 407 between the housing 402 and the base 405. The impurities and dust particles filtered in the purification component 5 are removed by vibration, ensuring the filtration efficiency of the purification component 5. The fallen impurities and dust particles are collected in the collection box 403.

[0026] Reference Figure 1 and Figure 2 An insulation layer 12 is fixedly fitted on the surface of the enclosure 402. An electric heating wire 13 is fixedly connected to the inner wall of the insulation layer 12. The insulation layer 12 can be made of materials such as glass wool, which can minimize the loss of internal temperature of the enclosure 402. The electric heating wire 13 inside the insulation layer 12 heats the enclosure 402 to a certain extent, further increasing the temperature of the high-temperature flue gas.

[0027] Reference Figure 2The purification component 5 includes a mounting bracket 501. One side of the mounting bracket 501 is fixedly connected to the inner wall of the housing 402. Filter plates 502 are fixedly connected to the inner wall of the mounting bracket 501. There are multiple filter plates 502. Through the purification component 5, the mounting bracket 501 in the purification component 5 plays a major role in integration and fixation. The multi-layer filter plates 502 can use different materials such as filter screens and activated carbon to perform different functional filtration to ensure the purity of high-temperature flue gas.

[0028] Reference Figure 1 and Figure 2 The surface of the spring 407 is covered with sound insulation cotton 14. One side of the sound insulation cotton 14 is fixedly connected to the bottom of the housing 402, and the other side of the sound insulation cotton 14 is fixedly connected to the top of the base 405. By using the sound insulation cotton 14, the elastic sound insulation cotton 14 can be fixedly connected between the housing 402 and the base 405, which can reduce the sound between the roller 10 and the cam 8 as much as possible.

[0029] Working principle: High-temperature flue gas in the kiln body 1 is transported to the housing 402 in the vibration mechanism 4 through the heating pipe 3. The base 405 in the vibration mechanism 4 plays a major supporting role, and the top cover 401 can improve the emission efficiency of high-temperature flue gas. The high-temperature flue gas is filtered by the purification component 5 to remove impurities and dust. The heat exhaust pipe 408 can be connected to external equipment through a flange. The filtered high-temperature flue gas is transported to the required equipment through the heat exhaust pipe 408. The motor 11 can be regarded as the driving source of the vibration mechanism 4. The motor 11 can drive the transmission shaft 7 to rotate along the bearing 6. While the transmission shaft 7 rotates, it drives the coaxially fixed cam 8 to rotate. Since the housing 402 is in contact with the cam 8 through the extension rod 9 and the roller 10, the cam 8 holds... During continuous rotation, the protruding part can drive the box 402 to vibrate continuously through the roller 10 and the extension rod 9. The sound insulation cotton 14 is fixedly connected between the box 402 and the base 405, which can reduce the noise between the roller 10 and the cam 8 as much as possible. The spring 407 between the box 402 and the base 405 can improve the vibration effect, and the impurities and dust particles filtered in the purification component 5 are removed by vibration, so as to ensure the filtration efficiency of the purification component 5. The fallen impurities and dust particles are collected in the collection box 403. The insulation layer 12 can be made of materials such as glass wool, which can minimize the loss of internal temperature of the box 402. The electric heating wire 13 inside the insulation layer 12 heats the box 402 to a certain extent, further increasing the temperature of the high-temperature flue gas.
