A fly ash hollow microsphere production equipment

Abstract

The present invention discloses a fly ash hollow microbead production device, which relates to the technical field of fly ash hollow microbead production devices. The fly ash hollow microbead production device includes a shell and a bracket. The fly ash hollow microbead production device uses the original device to make the manufactured hollow microbeads fall into a discharge bin first, and then uses a sieve plate to directly screen the products, screening out products that do not meet the size requirements. The motor drives the rotating shaft to rotate, driving the connecting rod and the stirring plate to rotate in the discharge bin, stirring the hollow microbeads, increasing the rolling speed and range of the hollow microbeads in the discharge bin, allowing all aspects of the hollow microbeads to come into contact with air, thereby achieving the effect of faster cooling of the hollow microbeads. This solves the problem that after the hollow microbeads are manufactured, they are fixed in the discharge bin, making it difficult to dissipate heat, and the sieve plate cannot screen out unqualified products that meet the specifications due to thermal expansion.

[0002] Fly ash, the industrial ash residue emitted by coal-fired power plants, not only occupies significant land resources for storage but also causes serious environmental pollution. Therefore, research into its comprehensive utilization is of great significance from both an economic and environmental perspective. Fly ash hollow microspheres are a new multifunctional granular material extracted from fly ash. They offer excellent properties such as light weight, small particle size, strong wear resistance, high compressive strength, good dispersibility and flowability, reflectivity, and non-toxicity. They can replace more expensive artificial hollow microspheres in applications such as building materials, rubber, plastics, aerospace, and electronics, leveraging their abundant raw material resources and low cost.

[0003] Patent announcement number CN208667463U is a glass microbead production equipment, which has an ignition port and an air supply port on the outer peripheral side of the support, and is provided with an annular burner, a tubular combustion unit and a cooling unit in sequence from bottom to top. This application designs the annular burner into an annular structure, and the annular burner is provided with multiple fuel nozzles, the fuel nozzles are connected to the annular cavity, and the annular cavity is sealed and connected to the fuel unit, so as to provide a concentrated and continuous central flame over a large range; this application provides an expansion joint on the inner peripheral side of the cooling unit, and the top of the cooling unit is connected to the induced draft fan through a pipeline. The position of the combustion outlet on the upper part of the tubular combustion unit is higher than the position of the discharge bin, so that the semi-finished glass microbeads entering the cooling unit from the combustion outlet fall along the wall after cooling, fall into the discharge bin and then the product is recovered.

[0016] The present invention provides a fly ash hollow microsphere production device, which has the following beneficial effects:

[0017] (1) The present invention is provided with a screening device. When producing fly ash hollow microbeads, the hollow microbeads produced are first dropped into the discharge bin by the device of the original equipment, and the products are directly screened by the sieve plate to screen out the products of unqualified size. The motor drives the rotating shaft to rotate, driving the connecting rod and the stirring plate to rotate in the discharge bin, and the hollow microbeads are moved, thereby increasing the rolling speed and range of the hollow microbeads in the discharge bin, so that all aspects of the hollow microbeads can be in contact with the air, thereby achieving the effect of cooling the hollow microbeads faster, solving the problem of the hollow microbeads being heated during discharge after being produced. The sieve is fixed in the bin and it is difficult to dissipate heat, so the screen plate cannot screen out unqualified products that have reached the specifications due to the thermal expansion effect. While screening out unqualified products, the stirring plate drives the first spring and the knocking block to rotate. When rotating to the inclined block, the knocking block is squeezed by the inclined block to compress the first spring. When it continues to rotate until it leaves the inclined block, the knocking block cooperates with the elastic force of the first spring to knock on the inner wall of the discharge bin, thereby vibrating the discharge bin and turning the hollow microbeads over in the discharge bin, solving the problem that the hollow microbeads are stacked together and the unqualified products on the upper layer cannot be screened out.

[0018] (2) The present invention is provided with a crushing device, which drives the crushing barrel to rotate by rotating the rotating shaft in conjunction with the guide rod and the sliding rod. The rotation of the crushing barrel drives the protrusions on its outer wall to slide on the inner wall of the wave groove, so that the protrusions slide up and down along the wave groove while rotating, so that the crushing barrel slides up and down while rotating, so that the screened unqualified products can smoothly enter the crushing barrel when they fall, solving the problem that the distance between the discharge bin and the raw material trough is too large, and the unqualified products are easy to fall out along the inner wall of the shell or directly enter the combustion unit; when the crushing barrel slides up and down, the height of the connecting rod and the crushing block remains unchanged, and the crushing barrel collides with the crushing block when sliding up and down with the screened unqualified products. The pressure between the crushing block and the crushing barrel crushes the unqualified products, thereby crushing the unqualified products, making it convenient for the unqualified products to fall from the crushing barrel into the raw material trough, solving the problem that the hollow microspheres that have been fired and formed are difficult to fire again, and avoiding the problem that the round hollow microspheres are easy to roll out of the raw material trough.

[0019] (3) The present invention is provided with an auxiliary device, which drives the connecting plate to slide up and down by sliding the crushing cylinder up and down, and the connecting plate drives the hinged plate to move up and down, and cooperates with the fixed plate to push the scraper plate toward the bracket, thereby pushing the powder generated by the crushed unqualified hollow microspheres to the center, making it convenient for the fly ash to enter the combustion unit again and be re-fired, solving the problem that the crushed fly ash is piled up and cannot enter the combustion unit for re-firing by itself; while pushing the fly ash to the combustion unit, the hinged rod drives the grinding hammer to grind the fly ash, thereby further grinding the large pieces of hollow microspheres that cannot pass through the feed trough into powder, solving the problem that the hollow microspheres are too large to be completely reused.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-8 One embodiment of the present invention is: a fly ash hollow microsphere production equipment, including a shell 1 and a bracket 3, a steam drum 2 is fixed on the upper surface of the shell 1, the bracket 3 is fixedly placed on a horizontal plane, a combustion unit is arranged inside the bracket 3, an annular burner 4 is fixed on the outer wall of the bracket 3, a raw material trough 5 is fixed on the outer wall of the bracket 3, a side wall of the raw material trough 5 is provided with a feed trough connected to the combustion unit, a discharge bin 6 is fixed on the inner wall of the shell 1, and a screening device is arranged inside the discharge bin 6 to facilitate screening of products with unqualified sizes.

[0031] The screening device includes a motor 71, a rotating shaft 72, a connecting rod 73, a stirring plate 74, a first spring 75, a knocking block 76 and a ramp block 77. The motor 71 is fixedly connected to the upper surface of the steam drum 2, and the rotating shaft 72 is fixedly connected to the output end of the motor 71. When the motor 71 is started, the motor 71 drives the rotating shaft 72 to rotate. The connecting rod 73 is fixedly connected to the outer wall of the rotating shaft 72. When the rotating shaft 72 rotates, the connecting rod 73 is driven to rotate. The stirring plate 74 is fixedly connected to the end of the connecting rod 73 away from the rotating shaft 72. The connecting rod 73 drives the rotation to drive the stirring plate 74 to rotate, and the fired fly ash hollow microbeads are moved inside the discharge bin 6. The microbeads are moved by the movement of the stirring plate 74. The stirring plate 74 is slidably connected to the inner wall of the discharge bin 6, and a sieve plate is fixed on the bottom surface of the discharge bin 6. The upper surface of the sieve plate is slidably connected to the bottom surface of the stirring plate 74. A sliding groove is provided on the side wall of the stirring plate 74. The left end of the first spring 75 is fixedly connected to the inner wall of the sliding groove. When the stirring plate 74 rotates, the first spring 75 is driven to rotate by the side wall of the knocking block 76. The side wall of the knocking block 76 is fixedly connected to the right end of the first spring 75. When the first spring 75 rotates, the knocking block 76 is driven to rotate together. The inclined block 77 is fixedly connected to the inner wall of the discharge bin 6. When the motor 71 is started and the connecting rod 73 is rotated, the connecting rod 73 also drives the stirring plate 74, the first spring 75 and the knocking block 76 to rotate. The knocking block 76 contacts the inclined block 77 when rotating, and is squeezed by the inclined block 77 to slide in the direction of the rotating shaft 72. The knocking block 76 squeezes the first spring 75 when sliding toward the rotating shaft 72. When the knocking block 76 rotates away from the inclined block 77, it is squeezed by the first spring 75 to slide in the direction away from the rotating shaft 72. The knocking block 76 quickly strikes the inner wall of the discharge bin 6, causing the discharge bin 6 to shake rapidly and flip the hollow microspheres in the discharge bin 6. During the production of gray hollow microbeads, the original equipment allows the manufactured hollow microbeads to first fall into the discharge bin 6 and the sieve plate is used to directly screen the products, screening out products of unqualified size. The motor 71 drives the rotating shaft 72 to rotate, driving the connecting rod 73 and the stirring plate 74 to rotate in the discharge bin 6, stirring the hollow microbeads, increasing the rolling speed and range of the hollow microbeads in the discharge bin 6, so that all aspects of the hollow microbeads can come into contact with the air, thereby achieving the effect of faster cooling of the hollow microbeads. This solves the problem that the hollow microbeads are fixed in the discharge bin 6 after manufacture, making it difficult to dissipate heat, so that the sieve plate cannot screen out unqualified products that have reached the specifications due to thermal expansion effect.While screening out unqualified products, the stirring plate 74 drives the first spring 75 and the knocking block 76 to rotate. When the stirring plate 74 rotates to the inclined surface block 77, the inclined surface block 77 squeezes the knocking block 76, causing the knocking block 76 to compress the first spring 75. When the stirring plate 74 continues to rotate until it leaves the inclined surface block 77, the elastic force of the first spring 75 cooperates with the knocking block 76 to knock against the inner wall of the discharge bin 6, thereby vibrating the discharge bin 6 and causing the hollow microbeads to flip inside the discharge bin 6. This solves the problem of the hollow microbeads stacking together and being unable to screen out unqualified products in the upper layer.

[0032] When the present embodiment is working, the motor 71 is started, the motor 71 drives the rotating shaft 72 to rotate, and when the rotating shaft 72 rotates, the connecting rod 73 is driven to rotate, and the connecting rod 73 drives the rotation to drive the stirring plate 74 to rotate, and the fired fly ash hollow microspheres are moved inside the discharge bin 6. The hollow microspheres roll under the movement of the stirring plate 74, accelerating the reaction between the hollow microspheres and the air, so that the hollow microspheres are cooled faster. When the stirring plate 74 rotates, it drives the first spring 75 to rotate, and when the first spring 75 rotates, it drives the knocking block 76 to rotate together. Since the discharge bin 6 is fixed, when When the motor 71 starts and drives the connecting rod 73 to rotate, the connecting rod 73 also drives the stirring plate 74, the first spring 75 and the knocking block 76 to rotate. The knocking block 76 contacts the inclined block 77 when rotating, and is squeezed by the inclined block 77 to slide toward the rotating shaft 72. The knocking block 76 squeezes the first spring 75 when sliding toward the rotating shaft 72. When the knocking block 76 rotates away from the inclined block 77, it is squeezed by the first spring 75 to slide in the direction away from the rotating shaft 72. The knocking block 76 quickly strikes the inner wall of the discharge bin 6, causing the discharge bin 6 to shake rapidly, turning over the hollow microbeads in the discharge bin 6.

[0033] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, a crushing device for crushing unqualified products is provided below the discharge bin 6, and the crushing device includes a crushing barrel 81, a guide rod 82, a sliding rod 83, a protrusion 84, a wave groove 85, a connecting rod 86 and a crushing block 87. The crushing barrel 81 is fitted to the inner wall of the shell 1, and a fixed block is fixed to the bottom end of the rotating shaft 72. The guide rod 82 is fixedly connected to the bottom surface of the fixed block. The rotating shaft 72 drives the guide rod 82 on its bottom surface to rotate. The sliding rod 83 is fixedly connected to the inner wall of the crushing barrel 81. When the sliding rod 83 rotates, the crushing barrel 81 is driven to rotate. The outer wall of the sliding rod 83 is slidably connected to the inner wall of the guide rod 82. When the rod 82 rotates, the sliding rod 83 is driven to rotate together. The protrusion 84 is fixedly connected to the outer wall of the crushing cylinder 81. When the crushing cylinder 81 rotates, the protrusion 84 on its outer wall also rotates with the crushing cylinder 81. The wave groove 85 is opened on the inner wall of the shell 1. The outer wall of the protrusion 84 fits the inner wall of the wave groove 85. The protrusion 84 slides in the wave groove 85 when rotating, so that the protrusion 84 moves up and down while rotating. Since the protrusion 84 is fixedly connected to the outer wall of the crushing cylinder 81, the protrusion 84 can also drive the crushing cylinder 81 to slide up and down when rotating and moving up and down. The connecting rod 86 is fixedly connected to the side wall of the fixed block. The crushing block 87 is hinged The end of the connecting rod 86 away from the fixed block is connected, and the crushing cylinder 81 rotates and slides up and down at the same time, so that the connecting rod 86 fixedly connected to the side wall of the rotating shaft 72 drives the crushing block 87 to crush the hollow microbeads in the crushing cylinder 81. After the screening is completed, the crushing device drives the crushing cylinder 81 to rotate through the rotation of the rotating shaft 72 in conjunction with the guide rod 82 and the sliding rod 83. The rotation of the crushing cylinder 81 drives the protrusion 84 on its outer wall to slide on the inner wall of the wave groove 85, so that the protrusion 84 slides up and down along the wave groove 85 while rotating, so that the crushing cylinder 81 can slide up and down while rotating, so that the unqualified products screened out can smoothly enter when they fall. The crushing cylinder 81 solves the problem that the distance between the discharge bin 6 and the raw material trough 5 is too large, and unqualified products are easy to fall out along the inner wall of the shell 1 or directly enter the combustion unit; when the crushing cylinder 81 slides up and down, the height of the connecting rod 86 and the crushing block 87 remains unchanged, and the crushing cylinder 81 collides with the crushing block 87 when sliding up and down with the screened unqualified products. The pressure between the crushing block 87 and the crushing cylinder 81 crushes the unqualified products, thereby crushing the unqualified products and facilitating the unqualified products to fall from the crushing cylinder 81 into the raw material trough 5, solving the problem that the hollow microspheres that have been fired and formed are difficult to fire again, and avoiding the problem that the round hollow microspheres are easy to roll out of the raw material trough 5.

[0034] The inner wall of the raw material trough 5 is provided with an auxiliary device for assisting the reprocessing of unqualified products. The auxiliary device includes a connecting plate 91, a hinged plate 92, a limit rod 93, a scraper plate 94, a second spring 95, a hinged rod 96 and a grinding hammer 97. The connecting plate 91 is fixedly connected to the bottom surface of the crushing cylinder 81. When the crushing cylinder 81 slides downward, the connecting plate 91 is driven to move downward. The hinged plate 92 is hinged at the bottom end of the connecting plate 91. The downward movement of the connecting plate 91 drives the hinged plate 92 to move downward as well. The limit rod 93 is fixedly connected to the outer wall of the bracket 3. A guide bar is fixed on the upper surface of the raw material trough 5. The guide bar passes through the scraper plate 94. The hinged plate 92 pushes the scraper plate 94 to slide in the direction of the bracket 3, and the hinged plate 92 pushes the scraper plate 94 to a certain distance and then inserts it into the gap between the scraper plate 94 and the raw material trough 5, so that the hinged plate 92 rotates. When the hinged plate 92 rotates, it further pushes the scraper plate 94 to slide in the direction of the bracket 3, pushing the fly ash crushed by the crushing device to the center, so that the fly ash enters the combustion unit more quickly for secondary processing. One end of the second spring 95 is fixedly connected to the side wall of the fixed plate. When sliding, the second spring 95 is compressed, and the other end of the second spring 95 is fixedly connected to the end of the limit rod 93 away from the bracket 3. The hinged rod 96 is hinged to the inner wall of the scraper plate 94. When the scraper plate 94 slides, the hinged rod 96 is driven to rotate. The grinding hammer 97 is fixedly connected to the end of the hinged rod 96 away from the scraper plate 94. The hinged rod 96 pushes the grinding hammer 97 to slide along the bottom surface of the raw material trough 5. The two groups of grinding hammers 97 collide with each other to further grind the crushed hollow microbeads into powder. The auxiliary device drives the connecting plate 91 to slide up and down through the up and down sliding of the crushing cylinder 81, and the connecting plate 91 drives the hinged plate 92 to The fly ash is pushed up and down by the fixed plate, and the scraper plate 94 is pushed toward the bracket 3 to push the powder generated by the crushed unqualified hollow microspheres toward the center, so that the fly ash can enter the combustion unit again for re-firing, which solves the problem that the crushed fly ash is piled up and cannot enter the combustion unit for re-firing by itself; while pushing the fly ash toward the combustion unit, the hinged rod 96 drives the grinding hammer 97 to grind the fly ash, so that the large fragments of hollow microspheres that cannot pass through the feed trough are further crushed into powder, which solves the problem that the fragments of hollow microspheres are too large to be completely reused.

[0035] When this embodiment is working, the rotating shaft 72 drives the guide rod 82 on its bottom surface to rotate. When the guide rod 82 rotates, it drives the sliding rod 83 to rotate together. When the sliding rod 83 rotates, it drives the crushing barrel 81 to rotate. When the crushing barrel 81 rotates, the protrusion 84 on its outer wall also rotates together with the crushing barrel 81. The protrusion 84 slides in the wave groove 85 during rotation, so that the protrusion 84 moves up and down while rotating. Since the protrusion 84 is fixedly connected to the outer wall of the crushing barrel 81, the protrusion 84 can also drive the crushing barrel 81 to slide up and down when rotating and moving up and down. The crushing barrel 81 slides up and down while rotating, so that the connecting rod 86 fixedly connected to the side wall of the rotating shaft 72 drives the crushing block 87 to crush the hollow microspheres in the crushing barrel 81.

[0036] When the crushing cylinder 81 slides downward, it drives the connecting plate 91 to move downward, and drives the hinged plate 92 to move downward as well. When the hinged plate 92 moves downward, it pushes the fixed plate on the inner wall of the scraper plate 94 to slide in the direction of the bracket 3. The hinged plate 92 pushes the scraper plate 94 a certain distance and then inserts it into the gap between the scraper plate 94 and the raw material trough 5, so that the hinged plate 92 rotates. When the hinged plate 92 rotates, it further pushes the scraper plate 94 to slide in the direction of the bracket 3, pushing the fly ash crushed by the crushing device to the center, so that the fly ash enters the combustion unit more quickly for secondary processing. When the scraper plate 94 slides in the direction of the bracket 3, the second spring 95 is compressed. At the same time, the scraper plate 94 drives the hinged rod 96 to rotate, and the hinged rod 96 drives the grinding hammer 97 to slide along the bottom surface of the raw material trough 5. The two groups of grinding hammers 97 collide with each other, and the crushed hollow microbeads are further ground into powder.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
