Description

Technical Field

[0001] The invention relates to the field of cement production drying devices, in particular to a drying device for white cement production with a waste heat recovery function. Background Art

[0002] In the production process of white cement, it is necessary to crush the raw materials such as limestone, iron ore, coal, etc., and then mix them after crushing. The raw materials are generally transported by blasting, excavation, and generally undergo multiple crushing. The raw materials are mined in the open air. Some raw materials may contain a lot of water. After multiple crushing, they will be dried to facilitate subsequent mixing processing.

[0003] The existing patent (Announcement No.: CN216308376U) discloses a drying device for cement production, which relates to the field of cement production and includes a box body, and a motor is installed on one side of the outer wall of the box body. In the process of implementing the solution, the inventor found that the following problems in the prior art have not been well solved: 1. The drying device stirs and dries a large amount of cement raw materials, but during the stirring process, some cement raw materials inside the stirring tank are still piled together. At this time, the stirring cycle needs to be increased 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 process, it is difficult for the device to effectively remove the water vapor accumulated at the exhaust port during the drying process.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figures 1 to 11 The present invention provides a technical solution: a drying device for white cement production with waste heat recovery function, comprising: Support seat 1, the top of support seat 1 is fixedly connected with a conveying bracket 2, and the surface of conveying bracket 2 is movably connected with a synchronous conveyor belt 3, the top of the right side of conveying bracket 2 is fixedly connected with a mixer 4, the right side of the top of support seat 1 is fixedly connected with a support plate 5, and the right side of support plate 5 is fixedly connected with a paving cone plate 6, the bottom of paving cone plate 6 overlaps the top of synchronous conveyor belt 3. It should be noted that: a paving gap is set between the bottom of the left side of paving cone plate 6 and synchronous conveyor belt 3, when synchronous conveyor belt 3 transfers cement raw materials discharged from the mixer 4 to the position of paving cone plate 6, the cement raw materials are limited by the right side of paving cone plate 6, and the cement raw materials are spread out from the gap at the lower left side of paving cone plate 6.

[0019] The left side of the top of the support seat 1 is fixedly connected with a support tube 7, and the top of the support tube 7 is fixedly connected with a waste heat recovery pipe 8. It should be noted that: an exhaust fan is arranged inside the waste heat recovery pipe 8, so that the waste heat recovery pipe 8 can extract the excess drying airflow inside the support tube 7, and one end of the waste heat recovery pipe 8 is connected to the waste heat recovery tank, and the recovered hot air is used as the heat preservation outside the equipment. The recycling and use method and the waste heat recovery tank are both existing technologies and will not be described in detail here.

[0020] It also includes a sleeve 9, which is rotatably connected between the support plate 5 and the support tube 7. The inner wall of the sleeve 9 is fixedly connected with eight arc-shaped air guide plates 10 at equal intervals along the circumference, and the surface of the support plate 5 is symmetrically fixedly connected with a hot air intake pipe 11 that matches the arc-shaped air guide plates 10. It should be noted that the high-temperature drying airflow is transported to the inside of the sleeve 9 through the hot air intake pipe 11, and finally the high-temperature airflow is discharged from the position of the waste heat recovery pipe 8 at the top of the support tube 7.

[0021] The middle part of the synchronous conveyor belt 3 is movably inserted between the support plate 5, the sleeve 9 and the support tube 7. A raw material spreading mechanism 12 is movably connected between the left side of the synchronous conveyor belt 3 and the inner wall of the support tube 7. The cement raw material smoothed by the paving cone plate 6 is thinned by the raw material spreading mechanism 12. It should be noted that the side walls of the support plate 5 and the support tube 7 are both provided with conveying grooves that cooperate with the synchronous conveyor belt 3, and the upper position conveying groove is convenient for the cement raw material to be transported to pass through.

[0022] The left side of the inner wall of the support tube 7 is movably connected with a water vapor removal mechanism 13 that cooperates with the waste heat recovery pipe 8. The right side of the water vapor removal mechanism 13 is movably connected with the raw material spreading mechanism 12. During the operation of the raw material spreading mechanism 12, the water vapor at the position of the waste heat recovery pipe 8 is cleaned with the water vapor removal mechanism 13.

[0023] In this embodiment, Figures 1 to 11 As shown, the raw material spreading mechanism 12 includes a transmission motor 1201, which is fixedly connected to the front side of the support cylinder 7, and a shaft 1202 is fixedly connected to the rotating end of the transmission motor 1201, and one end of the shaft 1202 is rotatably connected to the inner wall of the support cylinder 7. It should be noted that the shaft 1202 is inserted between the synchronous moving belt 1203 and the synchronous conveyor belt 3.

[0024] Synchronous moving belts 1203 are arranged on both sides of the synchronous conveyor belt 3. Synchronous moving rollers 1204 are symmetrically rotated and connected between the two synchronous moving belts 1203. The synchronous moving rollers 1204 are movably inserted in the middle position of the synchronous conveyor belt 3, and the middle of the synchronous moving rollers 1204 cooperate with the middle of the synchronous conveyor belt 3 for transmission. The two ends of the synchronous moving rollers 1204 are rotatably connected to the inner wall position of the support cylinder 7. The two ends of the right synchronous moving roller 1204 are fixedly sleeved with synchronous gear rings 1205, and the two ends of the shaft 1202 are fixedly sleeved with synchronous half gears 1206. The two synchronous half gears 1206 correspond to the two synchronous gear rings 1205 one by one, and the surface of the synchronous half gear 1206 meshes with the surface of the synchronous gear ring 1205 for transmission. It should be noted that the surface of the synchronous moving belt 1203 is flush with the surface of the synchronous conveyor belt 3, and the synchronous moving belt 1203 is attached to the side wall position of the synchronous conveyor belt 3, which reduces the leakage of cement raw materials during transportation and thinning.

[0025] Pads 1207 are fixedly connected to both sides of the inner wall of the support tube 7, a T-shaped tooth plate 1208 is slidably connected to the middle of the pad 1207, a reset ring 1209 is fixedly sleeved on the left side of the T-shaped tooth plate 1208, a reset spring 1210 is movably connected between the side wall of the pad 1207 and the side wall of the reset ring 1209, and 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.

[0026] Both ends of the shaft 1202 are fixedly connected with a transmission half gear 1212, and the two transmission half gears 1212 correspond to the two T-shaped toothed plates 1208 one by one, and the bottom of the T-shaped toothed plates 1208 meshes with the surface of the transmission half gear 1212. It should be noted that the synchronous half gear 1206 is arranged between the two transmission half gears 1212, and the synchronous half gear 1206 will not contact the T-shaped toothed plates 1208 during rotation to avoid interference.

[0027] An L-shaped support block 1213 is fixedly connected to the middle part of the T-shaped tooth plate 1208, a diamond-shaped adjustment plate 1214 is fixedly connected between the two L-shaped support blocks 1213, and four waist-shaped grooves 1215 are symmetrically opened on the surface of the diamond-shaped adjustment plate 1214. A cross bar 1216 is symmetrically fixedly connected to the upper part of the inner wall of the support tube 7, and a reset scraper 1217 is symmetrically slidably connected to the surface of the left cross bar 1216. The two reset scrapers 1217 are respectively slidably connected to the surfaces of the two waist-shaped grooves 1215 on the left.

[0028] The surface of the right cross bar 1216 is symmetrically slidably connected with a paving scraper 1218, and the two paving scrapers 1218 are respectively slidably connected to the surfaces of the two waist-shaped grooves 1215 on the right side.

[0029] In this embodiment, Figures 1 to 11As shown, the bottoms of the reset scraper 1217 and the paving scraper 1218 are both chamfered, and the two chamfers are set in opposite directions, and a scraping gap is set between the bottom of the paving scraper 1218 and the top surface of the synchronous conveyor belt 3. It should be noted that when the two paving scrapers 1218 move in opposite directions, the cement raw materials on the top surface of the synchronous conveyor belt 3 are thinned through the scraping gap, and the scraping gap is set to 0.5 times the paving gap at the bottom of the paving cone.

[0030] The top of the reset scraper 1217 and the paving scraper 1218 are both arranged below the diamond-shaped adjustment plate 1214. The top of the reset scraper 1217 and the paving scraper 1218 are fixedly connected with a T-shaped sliding ring. The middle part of the T-shaped sliding ring is slidably connected to the inside of the corresponding waist-shaped groove 1215, and the upper part of the T-shaped sliding ring is slidably connected to the surface of the corresponding cross bar 1216. It should be noted that: since the reset scraper 1217 and the paving scraper 1218 are both slidably connected to the corresponding surface of the cross bar 1216 through a T-shaped sliding ring, when the diamond adjustment plate 1214 is translated, in the process of sliding cooperation between the waist-shaped groove 1215 and the T-shaped sliding ring, the T-shaped sliding ring carries the corresponding reset scraper 1217 or the paving scraper 1218 to slide on the surface of the cross bar 1216. At this time, the two reset scrapers 1217 can move relative to or away from each other, and at the same time, the direction of the away or relative movement of the two paving scrapers 1218 is opposite to that of the two reset scrapers 1217, ensuring that when the paving scraper 1218 is thinning the cement raw materials, the reset scraper 1217 can gather the thinned cement raw materials.

[0031] The bottom of the mixer 4 is fixedly connected with an electric discharge valve that cooperates with the synchronous conveyor belt 3. It should be noted that when the synchronous conveyor belt 3 stops intermittent operation, the electric discharge valve opens and quantitatively discharges the cement raw materials inside the mixer 4 into the top surface position of the synchronous conveyor belt 3. The matching use of the electric discharge valve and the synchronous conveyor belt 3 is a prior art and will not be described in detail here.

[0032] In this embodiment, Figures 1 to 11 As 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 1202 brings the synchronous half gear 1206 to disengage from the corresponding synchronous ring gear 1205, the shaft 1202 that continues to rotate brings the transmission half gear 1212 to mesh with the T-shaped toothed 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 the shaft 1202 rotates clockwise with the transmission motor 1201 during use.

[0033] The synchronous half gear 1206 is set as a large gear, and the synchronous ring gear 1205 is set as a small gear. It should be noted that: through the setting of the large and small gears, the shaft 1202 can carry the synchronous half gear 1206 to mesh with the synchronous ring gear 1205, and under the action of the synchronous moving roller 1204, the synchronous conveyor belt 3 can be stably intermittently operated, and the cement raw materials regularly discharged by the mixer 4 can be spread in portions.

[0034] In this embodiment, Figures 1 to 11 As shown, the water vapor removal mechanism 13 includes a support ring 1301, which is rotatably connected to the left side of the inner wall of the support tube 7. The surface of the support ring 1301 is symmetrically fixedly connected with an arc-shaped guide sleeve 1302. The two arc-shaped guide sleeves 1302 correspond to the two T-shaped tooth plates 1208 one by one. The middle of the arc-shaped guide sleeve 1302 is provided with an arc-shaped guide groove 1303, and the 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 pin 1211 on 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 carry the support ring 1301 to rotate forward and backward once at the inner wall position of the support tube 7.

[0035] A rectangular groove 1304 is formed on the side wall of the support ring 1301, and a filter plate 1305 is symmetrically and slidingly connected inside 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 overlaps with the inner wall of the support tube 7. An extrusion spring 1307 is fixedly connected between the left sides of the two filter plates 1305.

[0036] The inner wall of the support tube 7 is symmetrically fixedly connected with a wedge-shaped extrusion plate 1308 that matches the filter plate 1305. It should be noted that when the support ring 1301 turns over with the filter plate 1305 to the position corresponding to the wedge-shaped extrusion plate 1308, the wedge-shaped extrusion plate 1308 presses the adjacent filter plate 1305 to move toward the other filter plate 1305, and at this time, the water in the sponge pad 1306 is squeezed out, so that the squeezed water flows into the inner wall of the support tube 7 through the inclined surface of the wedge-shaped extrusion plate 1308, and finally discharged from the bottom of the support tube 7.

[0037] In this embodiment, Figures 1 to 11 As 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, the filter plates 1305 are slidably connected to the surface of the guide columns through the guide holes, and the extrusion spring 1307 is movably sleeved in the middle of the guide columns.

[0038] In this embodiment, Figures 1 to 11As shown, a one-way drain valve is fixedly connected to the bottom of the support tube 7, and a mounting bearing is fixedly connected between the inner wall of the support tube 7 and the surface of the support ring 1301. It should be noted that the one-way drain valve is set to facilitate the water squeezed out of the sponge pad 1306 to be discharged from the bottom of the support tube 7.

[0039] In this embodiment, Figures 1 to 11 As 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 tube 7, and the outer ring of the right support bearing is fixedly connected to the left side of the support plate 5, and the sleeve 9 and the arc-shaped air guide plate 10 are both made of PVC material. It should be noted that the weight of the sleeve 9 and the arc-shaped air guide plate 10 can be reduced by setting the PVC material, and other light-weight materials can also be used.

[0040] The use method and advantages of the present invention: The drying device for white cement production with waste heat recovery function has the following working process: like Figures 1 to 11 As shown, when in use, first start the transmission motor 1201 to make the transmission motor 1201 mesh with the synchronous ring gear 1205 on the synchronous moving roller 1204 in stages through the synchronous half gear 1206 on the shaft 1202, so that the synchronous conveyor belt 3 and the synchronous moving belt 1203 run intermittently under the action of the rotating synchronous moving roller 1204, and when the synchronous conveyor belt 3 stops transporting, the raw materials inside the mixer 4 are quantitatively transported to the surface of the synchronous conveyor belt 3 under the action of the electric discharge valve; When the cement raw materials on the surface of the synchronous conveyor belt 3 are transported to the position of the paving cone plate 6, the paving cone plate 6 flattens the cement raw materials on the surface of the synchronous conveyor belt 3, and then delivers a dry airflow to the inside of the sleeve 9 through the position of the hot air inlet pipe 11. At this time, the dry airflow acts on the surface of the arc-shaped air guide plate 10, so that the sleeve 9 rotates between the support tube 7 and the support plate 5, ensuring that the dry airflow is evenly distributed inside the sleeve 9 and drying the cement raw materials flattened on the surface of the synchronous conveyor belt 3. Then, the cement raw materials are transported by the intermittently running synchronous conveyor belt 3 to the direction of the diamond-shaped adjustment plate 1214 inside the support tube 7; When the synchronous half gear 1206 on the shaft 1202 is disengaged from the synchronous ring gear 1205 on the synchronous moving roller 1204, the transmission half gear 1212 on the shaft 1202 is meshed with the surface of the T-shaped toothed plate 1208, so that the T-shaped toothed plate 1208 moves to the right with the L-shaped support block 1213 and the diamond-shaped adjustment plate 1214. During the sliding process between the waist-shaped groove 1215 and the corresponding T-shaped sliding ring, the two paving scrapers 1218 on the right cross bar 1216 move in opposite directions, spreading the cement raw materials on the surface of the synchronous conveyor belt 3 between the two synchronous moving belts 1203, further improving the drying effect of the cement raw materials; At the same time, the two reset scrapers 1217 on the left cross bar 1216 move relative to each other. When the intermittent synchronous conveyor belt 3 transports the diluted cement raw materials to the position of the reset scraper 1217, the two relatively moving reset scrapers 1217 gather the diluted cement raw materials to the position of the synchronous conveyor belt 3 and transport them to the next process. When the transmission half gear 1212 is released from the engagement with the T-shaped tooth plate 1208, the reset spring 1210 brings the L-shaped support block 1213 and the diamond-shaped adjustment plate 1214 to reset and move. At this time, the reset scraper 1217 and the paving scraper 1218 are reset to the initial state, and then the synchronous conveyor belt 3 continues to intermittently transport the cement raw materials, so as to perform secondary paving and drying treatment on the cement raw materials continuously transported on the synchronous conveyor belt 3. When the T-shaped toothed plate 1208 moves back and forth, the guide pin 1211 at the end of the T-shaped toothed plate 1208 slides in cooperation with the arc-shaped guide groove 1303 in the middle of the arc-shaped guide sleeve 1302, so that the two arc-shaped guide sleeves 1302 rotate once inside the support tube 7 with the support ring 1301. 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 top surface of the support tube 7. When the support ring 1301 rotates to the extreme position, the support ring 130 The filter plate 1305 is pressed against the side wall of the adjacent wedge-shaped extrusion plate 1308, and the compressed filter plate 1305 moves toward the other filter plate 1305 under the restriction of the rectangular groove 1304, 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 tube 7 under the guidance of the inclined surface of the wedge-shaped extrusion plate 1308, so as to prevent the water vapor generated in the drying process inside the support tube 7 from dripping onto the surface of the cement raw material and affecting the drying quality.
