Description

Technical Field

[0001] The present invention relates to the technical field of soda ash calcining furnaces, and specifically relates to a soda ash calcining furnace device. Background Art

[0002] At present, for the light ash calcining furnaces used in the domestic soda ash industry, the largest calcining furnace specification is a diameter of φ3.6m, and the maximum single-unit production capacity scale is 300,000 tons / year. Now, as domestic soda ash plants are gradually expanded, the scale of the soda ash plants is getting larger and larger. The supporting calcining furnaces in the soda ash plants can only select the largest 300,000 tons / year equipment, which brings problems such as a large number of supporting units, many supporting equipment, and a large floor area. Especially in the current development of natural soda ash projects in China, the production capacity scale of the projects is much larger than that of general soda ash projects, and calcining furnaces with a larger production capacity are needed.

[0003] Among them, the Hou's soda ash production method is a commonly used application method. Soda ash is obtained by calcining sodium bicarbonate. However, in this process, sodium bicarbonate will agglomerate when subjected to high temperatures, and some agglomerates will adhere tightly to the inner wall of the furnace. Because such agglomerates are heated too much on a single side, the heating surface will be gelatinized, affecting the yield of the calcining furnace. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a soda ash calcining furnace device, including a base, a driving motor fixedly connected to the top of the base, four limiting rings fixedly connected to the output end of the driving motor, and a driving gear fixedly connected to the output shaft of the driving motor; A calcining mechanism, which provides heat and a placement position for calcining, and realizes the calcining of sodium bicarbonate powder by the device; A scraping mechanism, which is arranged on the inner wall of the calcining mechanism and is used to remove the residual agglomerates inside the calcining mechanism; A contact mechanism, which is fixedly connected to the inner wall of the scraping mechanism and is used to provide the basic power for the rotation of the scraping mechanism; Among them, before use, first pour sodium bicarbonate powder into the inner wall of the calcining mechanism. Under the drive of the driving motor, the calcining mechanism rotates, the contact mechanism drives the scraping mechanism to move a small distance, and then the scraping mechanism scrapes and rolls the agglomerates on the inner wall of the calcining mechanism.

[0005] Preferably, the calcining mechanism includes: A heating component, which is fixedly connected to the top of the base through a heating element; The heating element includes a heater fixedly connected to the top of the contact mechanism, and a heating cylinder is rotatably connected to the inner wall of the heater; A transmission component, which is fixedly connected to both ends of the heating cylinder through an input component; The input component includes plugging discs fixedly connected to both sides of the heated cylinder. A feed pipe is rotatably connected to the inner wall of the through hole of the left plugging disc. During use, the heater provides heat to heat the outer wall of the heated cylinder. In addition, one end of the heated cylinder near the feed pipe is in an upwardly tilted state.

[0006] Preferably, the scraping mechanism includes: A control component, which is rotatably connected to the inner wall of the plugging disc through a control member. The control member includes annular grooves opened on the inner walls of the two plugging discs. A hollow tube is rotatably connected to the inner walls of the two annular grooves. The outer wall of the hollow tube is in contact with the inner wall of the heated cylinder, and the inner wall of the hollow tube is filled with hydraulic oil. A scraping component, which is fixedly connected to the side wall of the hollow tube through a scraping member. The scraping member includes a second toothed ring fixedly connected to the side wall of the hollow tube. A rotating disc is rotatably connected to the side wall of the hollow tube. A fixing column is fixedly connected to the side wall of the rotating disc. A second rotating ring is fixedly connected to the side wall of the fixing column. A scraping knife is fixedly connected to the side wall of the second rotating ring. During rotation of the heated cylinder, the internal hollow tube will roll synchronously. At this time, the hydraulic oil will limit the rotation speed of the hollow tube and drive the scraping knife to scrape and clean the inner wall of the heated cylinder.

[0007] Preferably, the contact mechanism includes: A rotating component, which is fixedly connected to one end of the hollow tube away from the second toothed ring through a rotating member. The rotating member includes a rotating column fixedly connected to one end of the hollow tube away from the second toothed ring. A second chute is opened on the outer wall of the rotating column. A limiting component, which is fixedly connected to the side wall of the base through an induction member. The induction member includes a fixing frame fixedly connected to the side wall of the base. A second permanent magnet is fixedly connected to the side wall of the fixing frame. Before the equipment is used, the hollow tube is at the bottom of the heated cylinder. Through the limiting component and the rotating component, when the equipment starts to operate, the rotation of the heated cylinder will first drive the hollow tube to operate synchronously. After exceeding the magnetic induction range of the second permanent magnet, the hollow tube will slowly rotate downward along the inner wall of the heated cylinder.

[0008] Preferably, the heating component includes a first rotating ring fixedly connected to the outer wall of the heated cylinder. A first toothed ring is fixedly connected to the outer wall of the heated cylinder. The outer wall of the first toothed ring is meshed with the outer wall of the driving gear. The outer wall of the first rotating ring is rotatably connected to the outer wall of the limiting ring. The driving motor drives the first toothed ring and the heated cylinder to rotate through the driving gear. At this time, the limiting ring will support and limit the first rotating ring and the heated cylinder.

[0009] Preferably, the transmission component includes a discharge port formed at one end of the heating cylinder away from the feed pipe; Among them, under the influence of the inclination angle of the heating cylinder, as the heating cylinder rotates, the sodium bicarbonate powder inside the heating cylinder will slowly move towards the discharge port and finally fall out through the discharge port.

[0010] Preferably, the control component includes a protruding block fixedly connected to the inner wall of the annular groove; Among them, the hydraulic oil is a liquid with relatively high viscosity. When the hollow tube rotates due to the rotation of the heating cylinder, the internal hydraulic oil cannot immediately make a synchronous movement, resulting in a decrease in the rolling efficiency of the hollow tube. Under the slow rotation of the heating cylinder, the hollow tube will sway back and forth along the inner wall of the heating cylinder.

[0011] Preferably, the scraping component includes a torsion spring fixedly connected to the outer wall of the fixed column. The other end of the torsion spring is fixedly connected to the outer wall of the second rotating ring. A first sliding groove is formed in the side wall of the rotating disc. A second slider is slidably connected to the inner wall of the first sliding groove. A first spring is fixedly connected to the side wall of the second slider; Among them, when the hollow tube rolls downward, the rotating force will be transmitted to the rotating disc and the fixed column through the second toothed ring and the second slider. The rotating fixed column forces the second rotating ring to closely adhere to the inner wall of the heating cylinder through the torsion spring.

[0012] Preferably, the rotating component includes a third slider slidably connected to the inner wall of the second sliding groove; Among them, under the attraction of the second permanent magnet, the third slider will move outward along the outer wall of the second sliding groove and enter the gap position of the protruding block, enabling the heating cylinder to move synchronously through the protruding block and the third slider, so that when the hollow tube is in a lower position, the third slider can drive the hollow tube to a higher position.

[0013] Preferably, the limiting component includes a first permanent magnet fixedly connected to the side wall of the third slider, a second spring fixedly connected to the side wall of the third slider, and the other end of the second spring is fixedly connected to the inner wall of the second sliding groove; Among them, the magnetism generated by the second permanent magnet will drive the first permanent magnet and the third slider to move outward, causing the second spring to deform. After the third slider exceeds the magnetic range of the second permanent magnet, the deformed second spring drives the third slider to reset.

[0014] The present invention has the following beneficial effects: (1)When the hollow tube rolls a short distance to the left and right, the hollow tube as a whole rotates counterclockwise at this time. The hollow tube will drive the fixed column and the second rotating ring to rotate synchronously. During this process, the fixed column forces the second rotating ring to rotate counterclockwise synchronously through the torsion spring, so that the second rotating ring drives the scraping knife to closely adhere to the inner wall of the heating cylinder. As the hollow tube rolls left and right on the inner wall of the rotating heating cylinder, the scraping knife will scrape the outer wall of the heating cylinder to remove most of the lumps inside the heating cylinder; (2)When the hollow tube of the present invention is affected by the rotation of the external heating cylinder, the overall rotation direction is still counterclockwise. When the torsion spring is twisted to the maximum value, the outer wall of the scraping knife is in close contact with the inner wall of the heating cylinder. At this time, the scraping knife will limit the rotation angles of the fixed column and the rotating disc, so that the rotation of the hollow tube will no longer be able to drive the rotating disc to rotate. When the hollow tube rotates, the rotating force generated by the hollow tube and the second toothed ring will press the second slider, so that the second slider slides along the inner wall of the first chute towards the center of the rotating disc, briefly contacting the contact relationship between the second slider and the inner wall of the second toothed ring. After the hollow tube finishes rotating, the first spring drives the second slider to re - latch on the inner wall of the second toothed ring, effectively offsetting part of the rotational pressure; (3)When the second slider is separated from the second toothed ring, at this time, because the torsion spring is at the maximum torsion, the released pressure still forces the scraping knife to closely adhere to the inner wall of the heating cylinder. Through the application of the above components, it is ensured that during the time when the second slider is disconnected from the second toothed ring, the scraping knife still closely adheres to the inner wall of the heating cylinder, ensuring the scraping efficiency.

[0015] (4)When the device is started or when the rolling speed of the hollow tube is too fast, the hollow tube will be at the bottom of the heating cylinder again. At this time, the heating cylinder continues to rotate, and the first permanent magnet at the bottom will have a magnetic reaction with the second permanent magnet, so that the third slider moves outward along the inner wall of the second chute. The heating cylinder will drive the hollow tube to move upward through the protruding block and the third slider, and after the first permanent magnet is out of the magnetic attraction range of the second permanent magnet, the second spring drives the third slider to contract. At this time, the hollow tube will be at the side wall of the heating cylinder again. Description of the Drawings

[0021] The calcining mechanism 1 includes: The heating component 11 is fixedly connected to the top of the base 13 through a heating element; The heating element includes a heater 111 fixedly connected to the top of the contact mechanism 3, and a heated cylinder 112 is rotatably connected to the inner wall of the heater 111; The transmission component 12 is fixedly connected to both ends of the heated cylinder 112 through an input component; The input component includes plugging disks 121 fixedly connected to both sides of the heated cylinder 112, and a feed pipe 122 is rotatably connected to the inner wall of the through hole of the left plugging disk 121; Among them, during use, the heater 111 provides heat to heat the outer wall of the heated cylinder 112. In addition, one end of the heated cylinder 112 close to the feed pipe 122 is in an upturned state.

[0022] The scraping mechanism 2 includes: The control component 21 is rotatably connected to the inner wall of the plugging disk 121 through a control component; The control component includes annular grooves 211 opened on the inner walls of the two plugging disks 121, a hollow tube 213 is rotatably connected to the inner walls of the two annular grooves 211, the outer wall of the hollow tube 213 is in contact with the inner wall of the heated cylinder 112, and hydraulic oil 214 is filled in the inner wall of the hollow tube 213; The scraping component 22 is fixedly connected to the side wall of the hollow tube 213 through a scraping component; The scraping member includes a second toothed ring 221 fixedly connected to the side wall of the hollow tube 213. A rotating disk 222 is rotatably connected to the side wall of the hollow tube 213. A fixing column 223 is fixedly connected to the side wall of the rotating disk 222. A second rotating ring 224 is fixedly connected to the side wall of the fixing column 223. A scraping knife 225 is fixedly connected to the side wall of the second rotating ring 224; Wherein, when the heating cylinder 112 rotates, the internal hollow tube 213 will roll synchronously. At this time, the hydraulic oil 214 will limit the rotation speed of the hollow tube 213 and drive the scraping knife 225 to scrape and clean the inner wall of the heating cylinder 112.

[0023] The contact mechanism 3 includes: A rotating assembly 31, and the rotating assembly 31 is fixedly connected to one end of the hollow tube 213 away from the second toothed ring 221 through a rotating member; The rotating member includes a rotating column 311 fixedly connected to one end of the hollow tube 213 away from the second toothed ring 221. A second chute 312 is provided on the outer wall of the rotating column 311; A limiting assembly 32, and the limiting assembly 32 is fixedly connected to the side wall of the base 13 through an induction member; The induction member includes a fixing bracket 323 fixedly connected to the side wall of the base 13. A second permanent magnet 324 is fixedly connected to the side wall of the fixing bracket 323; Wherein, before the equipment is used, the hollow tube 213 is at the bottom of the heating cylinder 112. Through the limiting assembly 32 and the rotating assembly 31, when the equipment starts to operate, the rotation of the heating cylinder 112 will first drive the hollow tube 213 to operate synchronously. After exceeding the magnetic induction range of the second permanent magnet 324, the hollow tube 213 will slowly rotate downward along the inner wall of the heating cylinder 112.

[0024] Embodiment 2, please refer to Figure 6 - Figure 11 In this invention, it is a soda ash calcining furnace equipment. On the basis of Example 1, the heating assembly 11 includes a first rotating ring 113 fixedly connected to the outer wall of the heating cylinder 112. A first toothed ring 114 is fixedly connected to the outer wall of the heating cylinder 112. The outer wall of the first toothed ring 114 is meshed with the outer wall of the driving gear 16. The outer wall of the first rotating ring 113 is rotatably connected to the outer wall of the limiting ring 15; Before use, first connect the external material pipe to the feed pipe 122 to ensure that the external material can be transmitted to the inner wall of the heating cylinder 112 through the feed pipe 122. Subsequently, connect the power supplies of the driving motor 14 and the heater 111, so that the heater 111 generates high heat, and the driving motor 14 drives the first toothed ring 114 and the heating cylinder 112 to rotate slowly through the driving gear 16; Among them, the drive motor 14 drives the first toothed ring 114 and the heating cylinder 112 to rotate through the drive gear 16, and at this time, the limiting ring 15 supports and positions the first rotating ring 113 and the heating cylinder 112.

[0025] The transmission component 12 includes a discharge port 123 opened at one end of the heating cylinder 112 away from the feed pipe 122; The powder material on the inner wall of the heating cylinder 112 moves slowly in the direction of the discharge port 123 under the influence of the inclination angle of the heating cylinder 112, and finally discharges outward from the discharge port 123; Among them, under the influence of the inclination angle of the heating cylinder 112, as the heating cylinder 112 rotates, the sodium bicarbonate powder inside the heating cylinder 112 will slowly move in the direction of the discharge port 123, and finally fall outward through the discharge port 123.

[0026] The control component 21 includes a protruding block 212 fixedly connected to the inner wall of the annular groove 211; When the heating cylinder 112 rotates, the internal hollow tube 213 will also roll synchronously. In this process, as Figure 5 shown, due to the slow rotation speed of the heating cylinder 112, the rotation speed of the hollow tube 213 is also relatively slow. This causes the hydraulic oil 214 to be unable to change immediately due to its own viscosity when the hollow tube 213 rolls, and forms Figure 7 the state of the shaded part in. In this state, the hydraulic oil 214 is inclined, the torque generated by the hydraulic oil 214 is greater than the torque generated by the hollow tube 213, and the centers of the hydraulic oil 214 and the hollow tube 213 are in a deviated state. At this time, the hydraulic oil 214 will press the hollow tube 213, driving the hollow tube 213 to rotate clockwise a small distance, so that when the hollow tube 213 rolls downward along the inner wall of the heating cylinder 112, the hollow tube 213 will roll a small distance in the opposite direction. After the hydraulic oil 214 reaches the horizontal state due to gravity, the torques generated by the hydraulic oil 214 and the hollow tube 213 are in the same direction, showing a state as Figure 8 shown. At this time, the hollow tube 213 will roll downward a small distance, and then stay in a stagnant state, repeating slow rotation.

[0027] The scraping component 22 includes a torsion spring 226 fixedly connected to the outer wall of the fixed column 223. The other end of the torsion spring 226 is fixedly connected to the outer wall of the second rotating ring 224. A first sliding groove 227 is opened on the side wall of the rotating disc 222. A second slider 228 is slidably connected to the inner wall of the first sliding groove 227. A first spring 229 is fixedly connected to the side wall of the second slider 228; When the hollow tube 213 rolls a small distance left and right, at this time, the whole hollow tube 213 rotates counterclockwise, showing a state as Figure 9In this state, the hollow tube 213 will drive the fixed column 223 and the second rotating ring 224 to rotate synchronously. During this process, the fixed column 223 forces the second rotating ring 224 to rotate counterclockwise synchronously through the torsion spring 226, so that the second rotating ring 224 drives the scraping knife 225 to closely adhere to the inner wall of the heating cylinder 112. As the hollow tube 213 rolls left and right on the inner wall of the rotating heating cylinder 112, the scraping knife 225 will scrape the outer wall of the heating cylinder 112 to remove most of the lumps inside the heating cylinder 112; When the hollow tube 213 rolls downward, the rotating force will be transmitted to the rotating disk 222 and the fixed column 223 through the second gear ring 221 and the second slider 228. The rotating fixed column 223 forces the second rotating ring 224 to closely adhere to the inner wall of the heating cylinder 112 through the torsion spring 226.

[0028] The rotating assembly 31 includes a third slider 313 slidably connected to the inner wall of the second chute 312; Affected by the rotation of the external heating cylinder 112, the overall rotation direction of the hollow tube 213 is still counterclockwise. When the torsion spring 226 is twisted to the maximum value, the outer wall of the scraping knife 225 is in close contact with the inner wall of the heating cylinder 112. At this time, the scraping knife 225 will limit the rotation angles of the fixed column 223 and the rotating disk 222, so that the rotation of the hollow tube 213 will no longer be able to drive the rotating disk 222 to rotate. When the hollow tube 213 rotates, the rotating force generated by the hollow tube 213 and the second gear ring 221 will press the second slider 228, causing the second slider 228 to slide along the inner wall of the first chute 227 towards the center of the rotating disk 222, briefly contacting the contact relationship between the second slider 228 and the inner wall of the second gear ring 221. After the hollow tube 213 completes rotation, the first spring 229 drives the second slider 228 to re - engage with the inner wall of the second gear ring 221, effectively offsetting part of the rotational pressure; Among them, under the attraction of the second permanent magnet 324, the third slider 313 will move outward along the outer wall of the second chute 312 and enter the gap position of the protruding block 212, so that the heating cylinder 112 moves synchronously through the protruding block 212 and the third slider 313, enabling the third slider 313 to drive the hollow tube 213 to a higher position when the hollow tube 213 is in a lower position.

[0029] The limiting assembly 32 includes a first permanent magnet 321 fixedly connected to the side wall of the third slider 313. A second spring 322 is fixedly connected to the side wall of the third slider 313, and the other end of the second spring 322 is fixedly connected to the inner wall of the second chute 312; When the second slider 228 is separated from the second gear ring 221, the torsion spring 226 is at the maximum of its torsion at this time. The released pressure still forces the scraping knife 225 to closely adhere to the inner wall of the heating cylinder 112. Through the application of the above components, it is ensured that during the time when the second slider 228 is disconnected from the second gear ring 221, the scraping knife 225 still closely adheres to the inner wall of the heating cylinder 112, ensuring the scraping efficiency.

[0030] When the device starts or when the rolling speed of the hollow tube 213 is too fast, the hollow tube 213 will be at the bottom of the heating cylinder 112 again. At this time, the heating cylinder 112 continues to rotate, and the first permanent magnet 321 at the bottom will have a magnetic reaction with the second permanent magnet 324, causing the third slider 313 to move outward along the inner wall of the second chute 312, presenting a state as shown in Figure 11 G in the figure. Then, the heating cylinder 112 will drive the hollow tube 213 to move upward through the protruding block 212 and the third slider 313. After the first permanent magnet 321 is out of the magnetic attraction range of the second permanent magnet 324, the second spring 322 drives the third slider 313 to contract. At this time, the hollow tube 213 will be at the side wall of the heating cylinder 112 again; Among them, the magnetism generated by the second permanent magnet 324 will drive the first permanent magnet 321 and the third slider 313 to move outward, causing the second spring 322 to deform. After the third slider 313 exceeds the magnetic range of the second permanent magnet 324, the deformed second spring 322 drives the third slider 313 to reset.

[0031] A specific application of this embodiment is as follows: Before use, first connect the external material pipe to the feed pipe 122 to ensure that the external material can be transmitted through the feed pipe 122 to the inner wall of the heating cylinder 112. Subsequently, connect the power supplies of the drive motor 14 and the heater 111, so that the heater 111 generates high heat, and the drive motor 14 drives the first gear ring 114 and the heating cylinder 112 to rotate slowly through the drive gear 16; The powder material on the inner wall of the heating cylinder 112 slowly moves in the direction of the discharge port 123 under the influence of the inclination angle of the heating cylinder 112, and finally discharges outward from the discharge port 123; When the heating cylinder 112 rotates, the internal hollow tube 213 will also roll synchronously. During this process, as shown in Figure 5 the figure, since the rotation speed of the heating cylinder 112 is slow, the rotation speed of the hollow tube 213 is also relatively slow. This causes the hydraulic oil 214 not to be able to transform immediately due to its own viscosity during the rolling of the hollow tube 213, and forms Figure 7the state of the shaded part, and in this state, the hydraulic oil 214 is inclined. The torque generated by the hydraulic oil 214 is greater than the torque generated by the hollow tube 213, and the centers of the hydraulic oil 214 and the hollow tube 213 are in a deflected state. At this time, the hydraulic oil 214 will press the hollow tube 213, driving the hollow tube 213 to rotate clockwise by a small distance. When the hollow tube 213 rolls downward along the inner wall of the heated cylinder 112, the hollow tube 213 will roll a small distance in the opposite direction. After the hydraulic oil 214 reaches the horizontal state due to gravity, the torques generated by the hydraulic oil 214 and the hollow tube 213 are in the same direction, as shown in Figure 8 In this state, the hollow tube 213 will roll downward by a small distance, and then it will be in a stagnant state again, repeating the slow rotation.

[0032] When the hollow tube 213 rolls a small distance left and right, at this time, the whole hollow tube 213 rotates counterclockwise, presenting a state as shown in Figure 9 In this state, the hollow tube 213 will drive the fixed column 223 and the second rotating ring 224 to rotate synchronously. During this process, the fixed column 223 forces the second rotating ring 224 to rotate counterclockwise synchronously through the torsion spring 226, so that the second rotating ring 224 drives the scraping knife 225 to closely adhere to the inner wall of the heated cylinder 112. As the hollow tube 213 rolls left and right on the inner wall of the rotating heated cylinder 112, the scraping knife 225 will scrape the outer wall of the heated cylinder 112 to remove most of the lumps inside the heated cylinder 112; Among them, affected by the rotation of the external heated cylinder 112, the overall rotation direction of the hollow tube 213 is still counterclockwise. When the torsion spring 226 is twisted to the maximum value, the outer wall of the scraping knife 225 is in close contact with the inner wall of the heated cylinder 112. At this time, the scraping knife 225 will limit the rotation angles of the fixed column 223 and the rotating disk 222, so that the rotation of the hollow tube 213 will no longer be able to drive the rotating disk 222 to rotate. When the hollow tube 213 rotates, the rotating force generated by the hollow tube 213 and the second gear ring 221 will press the second slider 228, causing the second slider 228 to slide along the inner wall of the first chute 227 towards the center of the rotating disk 222, briefly contacting the contact relationship between the second slider 228 and the inner wall of the second gear ring 221. After the hollow tube 213 finishes rotating, the first spring 229 drives the second slider 228 to re - engage with the inner wall of the second gear ring 221, effectively offsetting part of the rotational pressure; In addition, when the second slider 228 is separated from the second gear ring 221, at this time, because the torsion spring 226 is at the maximum torsion, the released pressure still forces the scraping knife 225 to closely adhere to the inner wall of the heated cylinder 112. Through the application of the above components, it is ensured that during the time when the second slider 228 is disconnected from the second gear ring 221, the scraping knife 225 still closely adheres to the inner wall of the heated cylinder 112, ensuring the scraping efficiency.

[0033] However, when the device is started or when the rolling speed of the hollow tube 213 is too fast, the hollow tube 213 will be at the bottom of the heating cylinder 112 again. At this time, the heating cylinder 112 continues to rotate, and the permanent magnet one 321 at the bottom will have a magnetic reaction with the permanent magnet two 324, causing the slider three 313 to move outward along the inner wall of the chute two 312, presenting the state of G in Figure 11 As shown in. Then, the heating cylinder 112 will drive the hollow tube 213 to move upward through the protruding block 212 and the slider three 313. After the permanent magnet one 321 is out of the magnetic attraction range of the permanent magnet two 324, the spring two 322 drives the slider three 313 to contract. At this time, the hollow tube 213 will be at the side wall of the heating cylinder 112 again.
