Description

Technical Field

[0001] This invention relates to the field of spray granulation tower technology, specifically to an energy-saving and environmentally friendly spray granulation tower for processing alumina ceramic materials. Background Technology

[0002] Alumina ceramics are ceramic materials with alumina as the main component. Alumina ceramics have good electrical conductivity, mechanical strength and high temperature resistance. Alumina ceramics are a widely used ceramic, and their superior performance has led to their widespread application in many fields, such as electronics, machinery and chemical industries. In the processing of alumina ceramic materials, spray granulation is a key step.

[0003] Traditional spray granulation towers typically use high-power heating equipment to dry the atomized slurry during the drying process. This not only leads to a significant waste of energy but also increases production costs. Furthermore, the drying process generates a large amount of waste gas, which often contains a large amount of heat. Direct emission of this waste gas not only pollutes the environment but also wastes a significant amount of heat. In the current context of global energy shortages, this contradicts the environmental protection policies advocated by the state.

[0004] In addition, traditional spray granulation towers collect spherical particles directly through the feed port after granulation, which often cannot screen the spherical particles. As a result, these spherical particles are uneven in size, which reduces the quality of the product and its market competitiveness. Summary of the Invention

[0014] Preferably, the mixing tank has a feed inlet at its upper end.

[0015] The beneficial effects of this invention are reflected in:

[0016] 1. This energy-saving and environmentally friendly spray granulation tower for processing alumina ceramic materials, by starting the drive motor, the output end of the drive motor will drive the first stirring shaft to rotate, the rotation of the first stirring shaft will drive the main cone wheel to rotate, the rotation of the main cone wheel will drive the transmission cone wheel to rotate, and through the cooperation of the cone wheel, the second stirring shaft can be easily rotated in the opposite direction. In this way, the multiple sets of stirring rods on the outside of the first and second stirring shafts can fully stir the material in the mixing tank, which can avoid the problem of substandard quality and size of spherical particles caused by uneven mixing of materials.

[0017] 2. This energy-saving and environmentally friendly spray granulation tower for processing alumina ceramic materials heats air into hot gas by starting a hot air blower. The hot air is then sprayed from multiple nozzles at the top of multiple branch pipes through a conveying pipe. The spray particles and hot gas work together in a mixed flow to dry and form spherical particles. The dried spherical particles gradually settle in the drying tower, are collected in the collection hopper, and discharged to the top of the screen for sieving. The hot gas rises and is collected by the gas collection hood. It then flows through the connecting pipe and through the spirally wound heating pipe on the outside of the mixing barrel. This heat exchange between the hot gas in the heating pipe and the mixed material in the mixing barrel raises the temperature of the material, thereby improving the stability of the material when it is sprayed from the nozzle to form particles. The exhaust gas after heating the material in the mixing barrel flows into the exhaust gas purification box for filtration and is then discharged through the exhaust pipe, effectively preventing harmful substances in the exhaust gas from polluting the environment.

[0018] 3. This energy-saving and environmentally friendly spray granulation tower for processing alumina ceramic materials uses a drive motor to rotate a driving wheel. Through the cooperation of a belt and a driven wheel, a rotating rod can easily drive an eccentric wheel to rotate. The rotation of the eccentric wheel moves the extrusion block. Through the cooperation of a sliding rod and a spring, a screen can easily vibrate and screen spherical particles. Unsatisfactory spherical particles are collected in a first collection box via a collection tray, while satisfactory spherical particles are filtered and screened by the screen and then collected in a second collection box. This allows for control over the uniformity of spherical particle size, improving product quality and market competitiveness. Attached Figure Description

A belt 62 is sleeved on the outer side of the drive wheel 61. A rotating rod 16 is rotatably connected to the upper end of the base plate 1. A driven wheel 63 is fixedly connected to the outer side of the rotating rod 16. The drive wheel 61 is connected to the driven wheel 63 through the belt 62. When the drive motor 4 is started, the output end of the drive motor 4 will also drive the drive wheel 61 to rotate. The rotation of the drive wheel 61 will drive the belt 62 to rotate, thereby realizing that the driven wheel 63 drives the rotating rod 16 to rotate.

[0034] In one embodiment of the present invention, the screening assembly includes a screen plate 18, a contact block 17 fixedly connected to the front end of the screen plate 18, an eccentric wheel 15 fixedly connected to the outer side of the rotating rod 16, the eccentric wheel 15 being movably connected to the contact block 17, a collection plate 19 fixedly connected to the rear end of the screen plate 18, a first collection box 20 disposed below the collection plate 19, the first collection box 20 being disposed at the upper end of the base plate 1, a support frame 24 fixedly connected to the outer side of the granulation tower box 25, the support frame 24 being fixedly connected to the upper end of the base plate 1, the upper end of the rotating rod 16 being rotatably connected to the support frame 24, and sliding rods 21 being slidably connected to both sides of the screen plate 18, both sliding rods 21 being fixedly connected to... On the inner side of the support frame 24, springs 22 are fitted on the outer sides of the two slide rods 21. The front ends of the two springs 22 are fixedly connected to the screen plate 18. A second collection box 23 is set below the screen plate 18. The rotation of the rotating rod 16 will drive the eccentric wheel 15 to rotate. The rotation of the eccentric wheel 15 will move the pressure block 17. With the cooperation of the slide rods 21 and the springs 22, the screen plate 18 can easily vibrate and screen the spherical particles. The spherical particles that do not meet the requirements will slide into the first collection box 20 through the collection plate 19 for collection. The spherical particles that meet the requirements will be filtered and screened by the screen plate 18 and then enter the second collection box 23 for collection.

[0035] In one embodiment of the present invention, a hot air blower 31 is provided at the rear end of the granulation tower box 25. The hot air blower 31 is fixedly installed on the upper end of the support frame 24. A conveying pipe 32 is fixedly connected to the front end of the hot air blower 31. Multiple branch pipes 33 are fixedly connected to the outside of the conveying pipe 32. Multiple jet nozzles 34 are fixedly connected to the upper end of each of the multiple branch pipes 33. The multiple jet nozzles 34 are all located in the inner cavity of the granulation tower box 25. By starting the hot air blower 31, the hot air blower 31 heats the air into hot air, which is then sprayed from the multiple jet nozzles 34 at the upper end of the multiple branch pipes 33 through the conveying pipe 32.

[0036] In one embodiment of the present invention, a diaphragm pump 36 is provided between the mixing tank 2 and the granulation tower box 25. The front end of the diaphragm pump 36 is fixedly connected to the mixing tank 2, and the rear end of the diaphragm pump 36 is fixedly connected to a conveying pipe 37. The other end of the conveying pipe 37 is fixedly connected to a nozzle 38. The nozzle 38 is located in the inner cavity of the granulation tower box 25. When the diaphragm pump 36 is started, the output end of the diaphragm pump 36 sprays the uniformly mixed material into the granulation tower box 25 through the conveying pipe 37 and the nozzle 38 at a certain pressure. At this time, a high-speed liquid film is formed, and the liquid film then splits into droplets.

[0037] As one embodiment of the present invention, the upper end of the mixing tank 2 is provided with a feed inlet 3, through which a certain proportion of material can be injected into the interior of the mixing tank 2.

[0038] It should be noted that during use, a certain proportion of material is first injected into the mixing tank 2 through the feed inlet 3. At this time, the drive motor 4 is started, and the output end of the drive motor 4 will drive the first stirring shaft 7 to rotate. The rotation of the first stirring shaft 7 will drive the main cone wheel 14 to rotate, and the rotation of the main cone wheel 14 will drive the transmission cone wheel 13 to rotate. With the cooperation of the cone wheel 12, the second stirring shaft 8 can be easily rotated in the opposite direction. Thus, the multiple sets of stirring rods 9 on the outside of the first stirring shaft 7 and the second stirring shaft 8 can be used to fully stir the material in the mixing tank 2. After stirring is completed... At this point, the diaphragm pump 36 is started. The output of the diaphragm pump 36 sprays the uniformly mixed material at a certain pressure through the conveying pipe 37 and nozzle 38 into the granulation tower box 25. A high-speed liquid film is formed, which then breaks into droplets. The hot air fan 31 is then started. The hot air fan 31 heats the air into hot gas, which is then sprayed through the conveying pipe 32 from multiple nozzles 34 at the top of multiple branch pipes 33. The mist and hot gas work together in a mixed flow to dry and form spherical particles. The dried spherical particles gradually settle in the drying tower, are collected in the collecting hopper 35, and then discharged. At the upper end of the sieve plate 18, hot air rises and is collected by the gas collecting hood 26. It then flows through the connecting pipe 27 and then through the spirally wound heating pipe 28 on the outside of the mixing drum 2. This allows the hot air in the heating pipe 28 to heat the mixed materials in the mixing drum 2 through heat exchange, raising the material's temperature and improving the stability of the particles formed when the material is ejected from the nozzle 38. The exhaust gas, after heating the materials in the mixing drum 2, finally flows into the exhaust gas purification box 29 for filtration and is then discharged through the exhaust pipe 30. When the drive motor 4 starts, its output also drives the active... The drive wheel 61 rotates, which in turn drives the belt 62 to rotate, thereby causing the driven wheel 63 to drive the rotating rod 16 to rotate. The rotation of the rotating rod 16 drives the eccentric wheel 15 to rotate, and the rotation of the eccentric wheel 15 causes the pressing block 17 to move. With the cooperation of the slide rod 21 and the spring 22, the sieve disc 18 can easily vibrate and screen the spherical particles. The spherical particles that do not meet the requirements will slide into the first collection box 20 through the collection disc 19 for collection, while the spherical particles that meet the requirements will be filtered and screened by the sieve disc 18 and then enter the second collection box 23 for collection.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
