Description

Technical Field

[0001] The invention relates to the technical field of ceramic granulation equipment, in particular to a device for producing dry granules of building ceramic raw materials. Background Art

[0002] Ceramic granulation is a key process that mixes ceramic powder with a liquid binder to form particles with a certain particle size and strength through physical action. It is widely used in the field of building ceramic green body forming. Spray drying granulation is one of the most widely used granulation methods in the preparation of ceramic powder. It forms spherical particles with good fluidity and controllable particle size distribution by atomizing the ceramic slurry into tiny droplets and quickly drying them under the action of hot air.

[0003] In the traditional ceramic dry granule spray granulation process, a centrifugal spray device is used to spray in a heating barrel. The droplets come into contact with hot air, and the water evaporates rapidly to form dry particles. In this process, high-temperature rapid drying may cause the particles to be hollow or cracked, affecting the molding density and quality. On the other hand, the particles attached to the barrel wall are generally knocked off by hitting the heating barrel through a vibration device. The knocking frequency is not high, which easily leads to the formation of large particles after the attached particles come into contact with the droplets, making the finished product particle size uneven. The liquid binder residue that is not completely atomized in the centrifugal spray device is easy to accumulate inside the equipment, which not only pollutes the working environment, but also may cause waste of raw materials and equipment corrosion. The hot and humid gases emitted during the high-temperature forming process are directly discharged, which not only causes a large amount of heat waste, but also increases the cost of workshop environment control.

The output end of the motor 21 is provided with a gear 211, and the driving pipe 23 is provided with a gear 231 meshing with the gear 211.

[0034] Combined with attachment Figure 1 , Attachment Figure 2 and attached Figure 7 As shown, the liquid conveying mechanism 7 includes a liquid storage tank 71 and a water pump 72. The liquid storage tank 71 stores a mixture of a solvent (water or an organic solvent) and a binder (PVA, PEG, etc.). The liquid storage tank 71 is provided with a stirring structure. The input end of the water pump 72 is connected to the liquid outlet pipe of the liquid storage tank 71, and the output end is connected to a liquid feeding pipe 73 extending into the inner side of the driving pipe 23. A liquid spray head 74 is provided at the end of the liquid feeding pipe 73. The powder conveying mechanism 8 includes a powder box 81 and a powder conveying pump 82.

The output end of the powder conveying pump 82 is connected to a powder feeding pipe 83 extending into the inner side of the extension pipe 24. A powder spray head 84 is provided at the end of the powder feeding pipe 83.

[0035] Combined with attachment Figure 9 and attached Figure 10 As shown, the scraper mechanism 33 includes a second motor 331 and an outer ring platform 333. The output end of the second motor 331 is provided with a gear three 332. The outer ring platform 333 is rotatably arranged on the outside of the upper cover platform 31 and the lower cover platform 32. The outer side of the outer ring platform 333 is provided with a gear ring 334 that meshes with the gear three 332. The inner side of the outer ring platform 333 is provided with an inner ring platform 335. The inner ring platform 335 is rotatably arranged in the gap between the upper cover platform 31 and the lower cover platform 32. The inner side of the inner ring platform 335 is provided with multiple scrapers 336. The scrapers 336 are in contact with the inside of the forming cavity 34.

[0036] In order to solve the problems of uneven mixing of raw materials and low forming efficiency in the manufacturing process of dry granular building ceramic raw materials, a combined structure of a mixing mechanism 2 and a high-temperature forming chamber 3 is designed. In the mixing mechanism 2, the motor 1 21 drives the mixing table 22 to rotate through the engagement of the gear 1 211 and the gear 2 231. The water pump 72 of the liquid conveying mechanism 7 sprays the liquid in the liquid storage tank 71 through the liquid delivery pipe 73 and the liquid spray head 74 into the inner cavity of the mixing table 22. The powder delivery pump 82 of the powder delivery mechanism 8 delivers the powder box 81 to the mixing table 22. The powder is sprayed into the inner cavity of the mixing table 22 by the powder spray head 84 through the powder feeding pipe 83. The mist liquid and powder are mixed in the mixing table 22. After the powder and liquid are combined into water droplets, they are evenly thrown into the forming cavity 34 by the centrifugal force of the centrifugal blades 221 and the centrifugal airflow formed by the centrifugal blades 221. The mixing table 22 rotates slowly, and the airflow at the axis of the mixing table 22 flows slowly, giving mixing time. The airflow is faster at the centrifugal blades 221, which can enable the mixed material to be quickly thrown into the forming cavity 34.

[0037] After the mixed material enters the high-temperature forming chamber 3, the air flow velocity entering the chamber decreases due to the increase in space. The high-temperature forming chamber 3 is composed of an upper cover table 31 and a lower cover table 32. The heating nets inside the two provide a high-temperature environment for the forming chamber 34. The material enters the forming chamber 34 from the inner cavity of the mixing table 22, and the surface of the mixed droplets is quickly dried under high temperature. At the same time, the motor 2 331 drives the outer ring table 333 to rotate intermittently through the engagement of the gear 3 332 and the gear ring 334, and the inner ring table 335 inside the outer ring table 333 rotates accordingly, so that the scraping table 336 attached to the inner wall of the forming chamber 34 intermittently scrapes the material and scrapes off the material adhering to the inner wall, ensuring the cleanliness of the inside of the forming chamber 34, avoiding mutual condensation into large particles, and improving the quality and efficiency of dry particle forming.

[0038] Combined with attachment Figure 11 and attached Figure 13As shown, an arc-shaped groove platform 321 is provided at the bottom discharge hole of the lower cover platform 32, a baffle 322 for blocking the discharge hole is slidingly provided inside the arc-shaped groove platform 321, a spring 323 connected to the arc-shaped groove platform 321 is provided at the rear end of the baffle 322, an inclined platform 324 extending out of the arc-shaped groove platform 321 is provided on the outer side of the baffle 322, a guide rod 337 is slidingly provided at the through hole of the bottom column of the outer ring platform 333, a inclined platform 2 338 cooperating with the inclined platform 1 324 is provided at the front end of the guide rod 337, a spring 2 339 connected to the bottom column of the outer ring platform 333 is provided at the rear end of the inclined platform 2 338, and a feeding platform 41 aligned with the discharge hole is provided on the low-temperature drying chamber 4.

[0039] In order to solve the problem of inflexible discharge control in the high-temperature forming chamber 3 and easy accumulation or leakage of materials, an arc-shaped groove platform 321 and a matching baffle 322 assembly are added at the discharge hole at the bottom of the lower cover platform 32. At the same time, a pushing structure linked to the baffle 322 is set at the bottom of the outer ring platform 333 to form a mechanically linked discharge control mechanism.

[0040] When the outer ring 333 is driven by the second motor 331 to rotate, the guide rod 337 at the bottom rotates synchronously with the outer ring. The inclined platform 2 338 at the front end of the guide rod 337 gradually approaches the inclined platform 1 324 outside the baffle 322. When the two come into contact, the inclined surface of the inclined platform 2 338 pushes the inclined platform 1 324, causing the baffle 322 to overcome the elastic force of the spring 1 323 and slide in the arc groove platform 321, thereby opening the discharge hole. At this time, the scraper 336 rotates in the forming cavity 34, scraping the semi-dried particles and pushing them to the discharge hole. The particles fall from the feed table 41 into the low-temperature drying chamber 4. When the elastic force of the spring 1 323 increases, the particles are removed. The resistance of inclined platform 1 324 to inclined platform 2 338 increases, and the guide rod 337 moves outward through the cooperation of the inclined surface, compressing spring 2 339. When the guide rod 337 rotates to the point where inclined platform 2 338 separates from inclined platform 1 324, spring 1 323 resets, pushing baffle 322 to re-block the discharge hole and stop discharging. The guide rod 337 is pushed back by spring 2 339 to prepare for the next pushing action. By intermittently opening and closing the discharge hole, the heat loss of the forming cavity 34 can be effectively reduced.

[0041] Combined with attachment Figure 10 , Attachment Figure 12 , Attachment Figure 13 and attached Figure 14 As shown, an exhaust chamber 311 is provided on the top of the upper cover platform 31, and a filter cover 312 is provided at the exhaust hole connecting the forming cavity 34 and the upper cover platform 31. The exhaust guide mechanism 6 includes an exhaust pipe 61 connected to the exhaust chamber 311, and a dehumidifier 62 is provided on the exhaust pipe 61. The end of the exhaust pipe 61 is connected to two exhaust branches 63 through a tee, and the end of the exhaust branch 63 is connected to a spiral coil 64. The spiral coil 64 is located in the spiral cavity inside the low-temperature drying chamber 4, and a plurality of inclined nozzles 65 are evenly provided on the spiral coil 64.

[0042] In order to solve the problems of poor discharge of hot and humid gas in the high-temperature forming chamber 3, insufficient utilization of waste heat and low drying efficiency in the low-temperature drying chamber 4, an exhaust chamber 311 and a filtering device are added to the top of the upper cover platform 31, and the hot and humid gas is converted into a drying heat source through the exhaust guide mechanism 6 to form a closed waste heat circulation system.

[0043] In the high-temperature forming chamber 3, the hot and humid gas generated during the material forming process enters the exhaust chamber 311 through the exhaust hole at the top of the forming cavity 34. After the dust is intercepted by the filter cover 312, it is transported to the exhaust guide mechanism 6 through the exhaust pipe 61. The dehumidifier 62 on the exhaust pipe 61 removes moisture from the gas. The dried hot air is diverted to the two exhaust branches 63 through the tee, and finally passes through the inclined nozzle 65 on the spiral coil 64 and is sprayed into the spiral cavity of the low-temperature drying chamber 4 in the form of an oblique airflow.

[0044] The low-temperature drying chamber 4 has an inverted conical structure. The internal spiral inclined plate 42 guides the material to spirally descend, thereby increasing the material movement stroke and the logistics retention time. The spiral coil 64 surrounds the spiral inclined plate 42. The inclination angle of the nozzle 65 makes the hot air and the falling direction of the material form a forward flow. On the one hand, the hot air will increase the internal temperature of the low-temperature drying chamber 4, complete the low-temperature drying of the material, prevent the particles from cracking due to excessive drying speed in a high-temperature drying environment, and ensure the quality of particle forming. On the other hand, the hot air blows the particles to roll, thereby preventing the material from accumulating and blocking on the spiral inclined plate 42.

[0045] Combined with attachment Figure 13 , Attachment Figure 15 and attached Figure 17 As shown, the discharging mechanism 5 includes a material box 54 and a separation cylinder 51 arranged at the bottom of the low-temperature drying chamber 4. A discharge port 43 is provided on the inner side of the bottom of the low-temperature drying chamber 4, and a partition 44 is provided on the inner side of the low-temperature drying chamber 4 above the discharge port 43. A filter plate 52 and a filter screen 55 are provided in the separation cylinder 51. The separation cylinder 51 is provided with a discharge cylinder 53 connected to the material box 54 at the filter plate 52, and a plurality of exhaust grooves 56 are provided on the outer wall of the separation cylinder 51 below the filter screen 55. The bottom of the extension tube 24 is rotatably connected to a waste liquid collecting pipe 91. A waste liquid bucket 9 is provided at the discharging mechanism 5, and the waste liquid collecting pipe 91 passes through the through hole on the separation cylinder 51 and is connected to the waste liquid bucket 9.

[0046] Combined with attachment Figure 5 , Attachment Figure 8 and attached Figure 16As shown, the filter plate 52 is arranged at an angle, and a ring plate 521 is provided on the outside thereof for sliding cooperation with the separation cylinder 51, and a positioning column 522 is provided on the outside of the ring plate 521 for sliding cooperation with the groove on the inner wall of the separation cylinder 51, and an axis ring 523 is provided at the bottom of the ring plate 521, and a collision platform 2 524 is provided at the bottom of the axis ring 523. An extension tube 24 is provided at the bottom of the mixing table 22, and the extension tube 24 passes through the axial through hole of the partition 44, the filter plate 52 and the axis ring 523. A bottom plate 241 is provided at the bottom of the extension tube 24, and a collision platform 1 242 cooperating with the collision platform 2 524 is provided on the bottom plate 241.

[0047] To address the problems of incomplete separation of granules and powder, inconvenient waste liquid collection, and easy clogging of the filter device during discharge in the production of dry granular building ceramic raw materials, a discharging mechanism 5 was designed that integrates separation, filtration, and waste liquid recovery functions. Automatic blockage removal is achieved through a mechanical linkage structure, optimizing the quality of the dry granular product and production continuity.

[0048] The material dried in the low-temperature drying chamber 4 falls into the separation cylinder 51 through the discharge port 43, and is first preliminarily screened by the inclined filter plate 52: the particulate material rolls along the inclined surface of the filter plate 52 to the discharge cylinder 53 and enters the material box 54 for collection. During collection, the material box 54 is in a closed state to prevent the airflow from carrying dust into the material box 54. The fine powder falls through the pores of the filter plate 52 and remains on the filter screen 55. The airflow is discharged from the exhaust slot 56. The partition 44 prevents the airflow from escaping from the top, which is conducive to the collection of powder. In this process, the extension pipe 24 at the bottom of the mixing table 22 rotates synchronously with the mixing table, and the collision platform 1 242 on the bottom plate 241 at the bottom of the extension pipe 24 periodically hits the collision platform 2 524 of the axis ring 523 at the bottom of the filter plate 52, causing the filter plate 52 to vibrate slightly along the ring plate 521 in the separation cylinder 51 to prevent the powder from clogging the pores of the filter plate.

[0049] In addition, the residual liquid that is not completely atomized by the liquid conveying mechanism 7, and the larger water droplets formed by the mixing table 22 in the inner cavity during mixing, fall into the extension tube 24. The water droplets mixed and condensed on the inner wall of the mixing table 22 form a water flow that flows down along the inner wall of the extension tube 24, and flows into the waste liquid collection pipe 91 through the extension tube 24. The waste liquid collection pipe 91 passes through the through hole of the separation cylinder 51 and is connected to the waste liquid barrel 9 to realize the centralized recovery and treatment of the waste liquid. On the one hand, it avoids the waste liquid from being retained in the extension tube 24, and on the other hand, it can divert the large water droplets to avoid being thrown into the forming cavity 34 and forming large particles.

[0050] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs structures and embodiments similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
