The top of the support base is fixedly connected with a conveying support, and the surface of the conveying support is movably connected with a synchronous conveyor belt. The top of the right side of the conveying support is fixedly connected with a mixer.

Description

Technical Field

[0001] The present invention relates to the field of cement production drying devices, and particularly to a drying device for white cement production with waste heat recovery function. Background Technique

[0002] During the production of white cement, raw materials such as limestone, iron ore, and coal need to be crushed, and after crushing, operations such as mixing are carried out. The raw materials are generally transported by blasting, excavation, and usually go through multiple crushings. The raw materials are mined in the open air, and some raw materials may contain a large amount of water. After multiple crushings, they will be dried to facilitate subsequent mixing and processing.

[0003] The existing patent (publication number: CN216308376U) discloses a drying device for cement production, which relates to the field of cement production, including a box body, and a motor is installed on one side of the outer wall of the box body. In the process of implementing this solution, the following problems in the existing technology are found to have not been well solved: 1. This drying device dries a large amount of cement raw materials through stirring. However, during the stirring process, some cement raw materials inside the stirring tank still accumulate together. At this time, it is necessary to increase the stirring cycle to ensure the drying effect, which affects the drying efficiency; 2. Since the moisture inside the cement raw materials will generate water vapor during the drying operation, it is difficult for this device to effectively remove the water vapor accumulated at the exhaust port during the drying operation. When the water vapor drips into the cement raw materials, it will affect the drying quality. Summary of the Invention

Detailed implementation manners

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a drying device for white cement production with waste heat recovery function, including:

[0045] A support base 1, on the top of the support base 1 is fixedly connected with a conveying support 2, and a synchronous conveyor belt 3 is movably connected to the surface of the conveying support 2. On the top of the right side of the conveying support 2 is fixedly connected with a mixer 4. On the right side of the top of the support base 1 is fixedly connected with a support plate 5, and on the right side of the support plate 5 is fixedly connected with a paving cone plate 6. The bottom of the paving cone plate 6 is lapped on the top of the synchronous conveyor belt 3. It should be noted that: there is a paving gap between the bottom of the left side of the paving cone plate 6 and the synchronous conveyor belt 3. When the synchronous conveyor belt 3 transports the cement raw materials discharged from the inside of the mixer 4 to the position of the paving cone plate 6, the cement raw materials are limited by the right side of the paving cone plate 6, and the cement raw materials are spread out from the gap at the lower part of the left side of the paving cone plate 6.

[0046] On the left side of the top of the support base 1 is fixedly connected with a support cylinder 7, and on the top of the support cylinder 7 is fixedly connected with a waste heat recovery pipe 8. It should be noted that: an air extraction fan is provided inside the waste heat recovery pipe 8, so that the waste heat recovery pipe 8 extracts the excess drying air flow inside the support cylinder 7. One end of the waste heat recovery pipe 8 is connected to the waste heat recovery tank, and the recovered hot air is used for heat preservation outside the equipment. This recovery and use method and the waste heat recovery tank are both prior arts and will not be described in detail here.

[0047] It further includes a sleeve 9, the sleeve 9 is rotatably connected between the support plate 5 and the support cylinder 7. On the inner wall of the sleeve 9 are fixedly connected with eight arc-shaped air guide plates 10 at equal intervals along the circumference. On the surface of the support plate 5 are symmetrically fixedly connected with hot air inlet pipes 11 that cooperate with the arc-shaped air guide plates 10. It should be noted that: the high-temperature drying air flow is transported into the inside of the sleeve 9 through the hot air inlet pipes 11, and finally the high-temperature air flow is discharged from the position of the waste heat recovery pipe 8 at the top of the support cylinder 7.

[0048] The middle part of the synchronous conveyor belt 3 is movably inserted between the support plate 5, the sleeve 9 and the support cylinder 7. Between the left side of the synchronous conveyor belt 3 and the inner wall of the support cylinder 7 is movably connected with a raw material spreading mechanism 12, and the raw material spreading mechanism 12 is used to thinly spread the cement raw materials leveled by the paving cone plate 6. It should be noted that: the side walls of the support plate 5 and the support cylinder 7 are both provided with conveying grooves that cooperate with the synchronous conveyor belt 3, and the conveying grooves at the upper position facilitate the transportation of the cement raw materials to pass through.

[0049] On the left side of the inner wall of the support cylinder 7, a water vapor removal mechanism 13 that cooperates with the waste heat recovery pipe 8 is movably connected. The right side of the water vapor removal mechanism 13 is movably connected to the raw material spreading mechanism 12. During the operation of the raw material spreading mechanism 12, the water vapor removal mechanism 13 is driven to clean the water vapor at the position of the waste heat recovery pipe 8.

[0050] In this embodiment, as Figures 1 to 11 shown, the raw material spreading mechanism 12 includes a driving motor 1201, which is fixedly connected to the front side of the support cylinder 7. The rotating end of the driving motor 1201 is fixedly connected to a shaft rod 1202, and one end of the shaft rod 1202 is rotatably connected to the inner wall position of the support cylinder 7. It should be noted that the shaft rod 1202 is inserted between the synchronous moving belt 1203 and the synchronous conveyor belt 3.

[0051] Synchronous moving belts 1203 are arranged on both sides of the synchronous conveyor belt 3. Synchronous moving rollers 1204 are symmetrically rotatably connected between the two synchronous moving belts 1203. The synchronous moving rollers 1204 are movably inserted through the middle position of the synchronous conveyor belt 3, and the middle of the synchronous moving rollers 1204 is in transmission cooperation with the middle of the synchronous conveyor belt 3. The two ends of the synchronous moving rollers 1204 are rotatably connected to the inner wall position of the support cylinder 7. Synchronous gear rings 1205 are fixedly sleeved on both ends of the right synchronous moving roller 1204. Synchronous half gears 1206 are fixedly sleeved on both ends of the shaft rod 1202. The two synchronous half gears 1206 correspond to the two synchronous gear rings 1205 one by one, and the surfaces of the synchronous half gears 1206 are in meshing transmission with the surfaces of the synchronous gear rings 1205. It should be noted that the surfaces of the synchronous moving belts 1203 are flush with the surface of the synchronous conveyor belt 3, and the synchronous moving belts 1203 are attached to the side walls of the synchronous conveyor belt 3 to reduce the situation of material leakage during the conveying and spreading of the cement raw materials.

[0052] On both sides of the inner wall of the support cylinder 7, there are fixedly connected cushion blocks 1207. A T-shaped tooth plate 1208 is slidably connected to the middle of the cushion blocks 1207. A return ring 1209 is fixedly sleeved on the left side of the T-shaped tooth plate 1208. A return spring 1210 is movably connected between the side wall of the cushion block 1207 and the side wall of the return ring 1209. A guide pin 1211 that cooperates with the water vapor removal mechanism 13 is fixedly connected to the left end of the T-shaped tooth plate 1208.

[0053] Driving half gears 1212 are fixedly connected to both ends of the shaft rod 1202. The two driving half gears 1212 correspond to the two T-shaped tooth plates 1208 one by one, and the bottom of the T-shaped tooth plate 1208 is in meshing transmission with the surface of the driving half gear 1212. It should be noted that the synchronous half gear 1206 is arranged between the two driving half gears 1212, and when the synchronous half gear 1206 rotates, it will not contact the T-shaped tooth plate 1208 to avoid interference.

[0054] In the middle of the T-shaped tooth plate 1208, an L-shaped support block 1213 is fixedly connected. Between the two L-shaped support blocks 1213, a diamond-shaped adjusting plate 1214 is fixedly connected. Four waist-shaped grooves 1215 are symmetrically formed on the surface of the diamond-shaped adjusting plate 1214. On the upper part of the inner wall of the support cylinder 7, cross bars 1216 are symmetrically and fixedly connected. On the surface of the left cross bar 1216, reset scraping plates 1217 are symmetrically and slidably connected. The two reset scraping plates 1217 are respectively slidably connected to the surfaces of the left two waist-shaped grooves 1215.

[0055] On the surface of the right cross bar 1216, spreading scraping plates 1218 are symmetrically and slidably connected. The two spreading scraping plates 1218 are respectively slidably connected to the surfaces of the right two waist-shaped grooves 1215.

[0056] In this embodiment, as Figures 1 to 11 shown, chamfers are provided at the bottoms of the reset scraping plate 1217 and the spreading scraping plate 1218, and the directions of the two chamfers are opposite. A scraping gap is provided between the bottom of the spreading scraping plate 1218 and the top surface of the synchronous conveyor belt 3. It should be noted that: when the two spreading scraping plates 1218 move away from each other, the cement raw materials on the top surface of the synchronous conveyor belt 3 are thinned through the scraping gap. The scraping gap is set to be 0.5 times the paving gap at the bottom of the paving cone plate.

[0057] The top of the reset scraping plate 1217 and the spreading scraping plate 1218 are both arranged below the diamond-shaped adjusting plate 1214. T-shaped sliding rings are fixedly connected to the tops of the reset scraping plate 1217 and the spreading scraping plate 1218. The middle parts of the T-shaped sliding rings are slidably connected inside the corresponding waist-shaped grooves 1215, and the upper parts of the T-shaped sliding rings are slidably connected to the surfaces of the corresponding cross bars 1216. It should be noted that: since the reset scraping plate 1217 and the spreading scraping plate 1218 are both slidably connected to the surface of the corresponding cross bar 1216 through the T-shaped sliding ring, when the diamond-shaped adjusting plate 1214 moves horizontally, during the sliding cooperation between the waist-shaped groove 1215 and the T-shaped sliding ring, the T-shaped sliding ring drives the corresponding reset scraping plate 1217 or spreading scraping plate 1218 to slide on the surface of the cross bar 1216. At this time, the two reset scraping plates 1217 can move relatively or away from each other, and at the same time, the directions in which the two spreading scraping plates 1218 move away from or towards each other are opposite to those of the two reset scraping plates 1217, ensuring that during the process of the spreading scraping plate 1218 thinning the cement raw materials, the reset scraping plate 1217 can gather the thinned cement raw materials.

[0058] An electric discharge valve that cooperates with the synchronous conveyor belt 3 is fixedly connected to the bottom of the mixer 4. It should be noted that: when the synchronous conveyor belt 3 stops running intermittently, the electric discharge valve opens and quantitatively discharges the cement raw materials inside the mixer 4 to the top surface position of the synchronous conveyor belt 3. The cooperation mode of the electric discharge valve and the synchronous conveyor belt 3 is an existing technology and will not be described in detail here.

[0059] In this embodiment, as Figures 1 to 11 shown, the teeth of the synchronous half gear 1206 and the transmission half gear 1212 are arranged in a staggered manner. It should be noted that: when the shaft rod 1202 drives the synchronous half gear 1206 to disengage from the corresponding synchronous gear ring 1205, the continuously rotating shaft rod 1202 drives the transmission half gear 1212 to mesh with the T-shaped tooth plate 1208 for transmission, so that the operation of the synchronous conveyor belt 3 and the operation of the paving scraper 1218 can be staggered; and during the use of the shaft rod 1202, it rotates clockwise along with the drive motor 1201.

[0060] The synchronous half gear 1206 is set as a large gear, and the synchronous gear ring 1205 is set as a small gear. It should be noted that: through the setting of the large and small gears, when the shaft rod 1202 drives the synchronous half gear 1206 to mesh with the synchronous gear ring 1205, under the action of the synchronous moving roller 1204, the synchronous conveyor belt 3 can operate stably in an intermittent manner, and the cement raw materials regularly discharged by the mixer 4 are paved in portions.

[0061] In this embodiment, as Figures 1 to 11 shown, the water vapor removal mechanism 13 includes a support ring 1301, the support ring 1301 is rotatably connected to the left side of the inner wall of the support cylinder 7, and arc-shaped guide sleeves 1302 are symmetrically and fixedly connected to the surface of the support ring 1301. The two arc-shaped guide sleeves 1302 correspond to the two T-shaped tooth plates 1208 one by one. An arc-shaped guide groove 1303 is formed in the middle of the arc-shaped guide sleeve 1302, and two guide pins 1211 are respectively slidably connected to the inside of the two arc-shaped guide grooves 1303. It should be noted that: when the T-shaped tooth plate 1208 reciprocates left and right, the guide pins 1211 on the T-shaped tooth plate 1208 cooperate with the arc-shaped guide grooves 1303 in the middle of the arc-shaped guide sleeve 1302 to slide, so that the two arc-shaped guide sleeves 1302 drive the support ring 1301 to rotate forward and backward once at the position of the inner wall of the support cylinder 7.

[0062] A rectangular groove 1304 is formed in the side wall of the support ring 1301, filter plates 1305 are symmetrically and slidably connected to the inside of the rectangular groove 1304, a sponge pad 1306 is fixedly connected between the middle parts of the two filter plates 1305, one side of the sponge pad 1306 abuts against the inner wall of the support cylinder 7, and a compression spring 1307 is fixedly connected between the left sides of the two filter plates 1305.

[0063] The inner wall of the support cylinder 7 is symmetrically and fixedly connected with wedge-shaped pressing plates 1308 that cooperate with the filter plate 1305. It should be noted that when the support ring 1301 drives the filter plate 1305 to flip to the position corresponding to the wedge-shaped pressing plate 1308, the wedge-shaped pressing plate 1308 presses against the adjacent filter plate 1305 and moves it in the direction of the other filter plate 1305. At this time, the water in the sponge pad 1306 is squeezed out, and the squeezed water flows into the position of the inner wall of the support cylinder 7 through the inclined surface of the wedge-shaped pressing plate 1308 and is finally discharged from the bottom of the support cylinder 7.

[0064] In this embodiment, as Figures 1 to 11 shown, guide columns are fixedly connected between the two sides of the inner wall of the rectangular groove 1304. Guide holes are opened on the left sides of the two filter plates 1305, and the filter plates 1305 are slidably connected to the surfaces of the guide columns through the guide holes. The compression spring 1307 is movably sleeved on the middle of the guide column.

[0065] In this embodiment, as Figures 1 to 11 shown, a one-way liquid discharge valve is fixedly connected to the bottom of the support cylinder 7, and a mounting bearing is fixedly connected between the inner wall of the support cylinder 7 and the surface of the support ring 1301. It should be noted that the setting of the one-way liquid discharge valve facilitates the discharge of the water squeezed out from the sponge pad 1306 from the bottom of the support cylinder 7.

[0066] In this embodiment, as Figures 1 to 11 shown, support bearings are fixedly sleeved on both sides of the sleeve 9. The outer ring of the left support bearing is fixedly connected to the right side of the support cylinder 7, and the outer ring of the right support bearing is fixedly connected to the left side of the support disc 5. The sleeve 9 and the arc-shaped air guide plate 10 are both made of PVC material. It should be noted that the use of PVC material reduces the weight of the sleeve 9 and the arc-shaped air guide plate 10. At the same time, other lightweight materials can also be used.

[0067] The usage method and advantages of the present invention: The drying device for white cement production with waste heat recovery function works as follows:

[0068] As Figures 1 to 11 shown, when in use, first start the driving motor 1201 to operate, so that the driving motor 1201 is intermittently engaged and driven with the synchronous gear ring 1205 on the synchronous moving roller 1204 through the synchronous half gear 1206 on the shaft rod 1202, so that the synchronous conveyor belt 3 and the synchronous moving belt 1203 operate intermittently under the action of the rotating synchronous moving roller 1204. And when the synchronous conveyor belt 3 pauses in transportation, under the action of the electric discharge valve, the raw materials inside the mixer 4 are quantitatively conveyed to the surface of the synchronous conveyor belt 3 as cement raw materials;

[0069] When the cement raw materials on the surface of the synchronous conveyor belt 3 are conveyed to the position of the spreading conical plate 6, the spreading conical plate 6 levels the cement raw materials on the surface of the synchronous conveyor belt 3. Then, drying air flow is conveyed into the interior of the sleeve 9 through the position of the hot air inlet pipe 11. At this time, the drying air flow acts on the surface of the arc-shaped air guide plate 10, causing the sleeve 9 to rotate between the support cylinder 7 and the support disk 5, ensuring that the drying air flow is evenly distributed inside the sleeve 9 and drying the cement raw materials leveled on the surface of the synchronous conveyor belt 3. Then, the cement raw materials are conveyed by the intermittently operating synchronous conveyor belt 3 towards the direction of the diamond-shaped adjusting plate 1214 inside the support cylinder 7;

[0070] When the synchronous half gear 1206 on the shaft rod 1202 disengages from the synchronous gear ring 1205 on the synchronous moving roller 1204, the driving half gear 1212 on the shaft rod 1202 meshes with and drives the surface of the T-shaped tooth plate 1208, causing the T-shaped tooth plate 1208 to drive the L-shaped support block 1213 and the diamond-shaped adjusting plate 1214 to move to the right. During the sliding process of the waist-shaped groove 1215 and the corresponding T-shaped sliding ring, at this time, the two spreading scrapers 1218 on the right cross bar 1216 move away from each other, thinning the cement raw materials on the surface of the synchronous conveyor belt 3 to between the two synchronous moving belts 1203, further improving the drying effect of the cement raw materials;

[0071] Meanwhile, the two reset scrapers 1217 on the left cross bar 1216 move relatively. When the intermittently operating synchronous conveyor belt 3 conveys the thinned cement raw materials to the position of the reset scrapers 1217, the two relatively moving reset scrapers 1217 gather the thinned cement raw materials to the position of the synchronous conveyor belt 3 and convey them to the next process. When the driving half gear 1212 disengages from the T-shaped tooth plate 1208, the reset spring 1210 drives the L-shaped support block 1213 and the diamond-shaped adjusting plate 1214 to move back to their original positions. At this time, the reset scrapers 1217 and the spreading scrapers 1218 return to their initial states. Then, the synchronous conveyor belt 3 continues to intermittently convey the cement raw materials, thereby performing secondary spreading and drying treatment on the continuously conveyed cement raw materials on the synchronous conveyor belt 3;

[0072] When the T-shaped tooth plate 1208 reciprocates, the guide pin 1211 at the end of the T-shaped tooth plate 1208 cooperates with the arc-shaped guide groove 1303 in the middle of the arc-shaped guide sleeve 1302 to slide, so that the two arc-shaped guide sleeves 1302 drive the support ring 1301 to rotate once inside the support cylinder 7. At this time, the sponge pad 1306 on the side wall of the support ring 1301 will remove the water vapor accumulated near the waste heat recovery pipe 8 on the inner top surface of the support cylinder 7. When the support ring 1301 rotates to the limit position, the support ring 1301 drives the filter plate 1305 to press against the side wall position of the adjacent wedge-shaped extrusion plate 1308. Under the restriction of the rectangular groove 1304, the compressed filter plate 1305 moves towards the other filter plate 1305, so that the sponge pad 1306 between the two filter plates 1305 is compressed to squeeze out the water inside. At this time, the squeezed water is discharged from the bottom of the support cylinder 7 under the guiding of the inclined surface of the wedge-shaped extrusion plate 1308, avoiding the water vapor generated during the drying process inside the support cylinder 7 from dripping onto the surface of the cement raw material and affecting the drying quality.
