Therefore, from the perspectives of economy and environmental protection, it is of great significance to carry out comprehensive utilization research on fly ash. Fly ash hollow microspheres are a new type of multifunctional particulate material selected from fly ash. It has excellent properties such as light weight, small particle size, strong wear resistance, high compressive strength, good dispersibility and fluidity, light reflection, non-toxicity, etc. It can replace the relatively high-cost artificial hollow microspheres and be applied to fields such as building materials, rubber, plastics, aerospace, electronics, etc., giving play to its advantages of rich raw materials and low price.

[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 sieving device. When producing fly ash hollow microspheres, the hollow microspheres made by the device of the original equipment first fall into the feeding and discharging bin, and the product is directly screened by the sieve plate. The unqualified products in terms of size are screened out. The motor drives the rotating shaft to rotate, driving the connecting rod and the stirring plate to rotate in the feeding and discharging bin, stirring the hollow microspheres, increasing the rolling speed and range of the hollow microspheres in the feeding and discharging bin, enabling all aspects of the hollow microspheres to come into contact with air, so as to achieve the effect of cooling the hollow microspheres faster, solving the problem that the hollow microspheres are fixed in the feeding and discharging bin after being made, difficult to dissipate heat, and the sieve plate cannot screen out the unqualified products that reach the specification due to the thermal expansion effect; while screening out the unqualified products, the stirring plate drives the first spring and the knocking block to rotate. When rotating to the inclined surface block, the knocking block compresses the first spring due to the extrusion of the inclined surface block on the knocking block. When continuing to rotate away from the inclined surface block, the knocking block knocks on the inner wall of the feeding and discharging bin in cooperation with the elastic force of the first spring, so as to vibrate the feeding and discharging bin and make the hollow microspheres turn over in the feeding and discharging bin, solving the problem that the hollow microspheres 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. By the rotation of the rotating shaft, cooperating with the guide rod and the sliding rod, the crushing cylinder is driven to rotate. By the rotation of the crushing cylinder, the convex blocks on its outer wall slide on the inner wall of the wave groove, so that the convex blocks slide up and down along the wave groove while rotating. Thus, the crushing cylinder not only rotates but also slides up and down, enabling the unqualified products screened out to smoothly fall into the crushing cylinder when dropping, solving the problem that the distance between the discharge bin and the raw material tank is too large, and the unqualified products are likely to fall out along the inner wall of the shell or directly enter the combustion unit; when the crushing cylinder slides up and down, the height of the connecting rod and the crushing block remains unchanged. When the crushing cylinder slides up and down with the screened-out unqualified products, it impacts the crushing block. The pressure between the crushing block and the crushing cylinder smashes the unqualified products, thus crushing the unqualified products, facilitating the unqualified products to fall from the crushing cylinder into the raw material tank, solving the problem that the formed hollow microspheres are difficult to be fired again, and avoiding the problem that the round hollow microspheres are likely to roll out of the raw material tank.

[0019] (3) The present invention is provided with an auxiliary device. By the up and down sliding of the crushing cylinder, the connecting plate is driven to slide up and down. The connecting plate drives the articulated plate to move up and down, and cooperates with the fixed plate to push the powder scraping plate towards the bracket direction, thus pushing the powder generated by the crushed unqualified hollow microspheres towards the center, facilitating the fly ash to enter the combustion unit again for firing, solving the problem that the fly ash after being crushed accumulates together and cannot enter the combustion unit by itself for re-firing; while pushing the fly ash towards the combustion unit, the grinding hammer is driven by the articulated rod to grind the fly ash, thus further crushing the large fragments of the hollow microspheres that cannot pass through the feeding groove into powder form, solving the problem that the fragments of the hollow microspheres are too large to be fully reused.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 8 , an embodiment of the present invention is: a fly ash hollow microsphere production device, including a housing 1 and a support 3. A steam drum 2 is fixed on the upper surface of the housing 1. The support 3 is fixedly placed on a horizontal plane. A combustion unit is arranged inside the support 3. An annular burner 4 is fixed on the outer wall of the support 3. A raw material tank 5 is fixed on the outer wall of the support 3. A feed trough is provided on the side wall of the raw material tank 5, which is connected to the combustion unit. A discharge bin 6 is fixed on the inner wall of the housing 1. A screening device for conveniently screening products with unqualified sizes is arranged inside the discharge bin 6.

[0031] The sieving 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 an inclined 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, it drives the connecting rod 73 to rotate. The stirring plate 74 is fixedly connected to one 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 stirs the fired fly ash hollow microspheres inside the discharge bin 6. The microspheres roll under the stirring of the stirring plate 74, accelerating the reaction between the hollow microspheres and the air, cooling the hollow microspheres, and reducing the situation where unqualified products caused by thermal expansion and contraction cannot be sieved. The stirring plate 74 is slidably connected to the inner wall of the discharge bin 6. A sieve plate is fixed to the bottom surface of the discharge bin 6, and 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, it drives the first spring 75 to rotate. 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, it drives the knocking block 76 to rotate together. The inclined block 77 is fixedly connected to the inner wall of the discharge bin 6. Since the discharge bin 6 is fixed, when the motor 71 is started to drive 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. When the knocking block 76 rotates and contacts the inclined block 77, it slides in the direction of the rotating shaft 72 under the extrusion of the inclined block 77. When the knocking block 76 slides towards the rotating shaft 72, it compresses the first spring 75. When the knocking block 76 rotates away from the inclined block 77, it slides in the direction away from the rotating shaft 72 under the extrusion of the first spring 75. The knocking block 76 rapidly impacts the inner wall of the discharge bin 6, causing the discharge bin 6 to vibrate rapidly and turning over the hollow microspheres in the discharge bin 6. When this sieving device is used in the production of fly ash hollow microspheres, the hollow microspheres made by the original equipment first fall into the discharge bin 6, and the sieve plate directly screens the products, screening out the products with unqualified dimensions. The motor 71 drives the rotating shaft 72 to rotate, driving the connecting rod 73 and the stirring plate 74 to rotate inside the discharge bin 6, stirring the hollow microspheres, increasing the rolling speed and range of the hollow microspheres in the discharge bin 6, enabling all aspects of the hollow microspheres to come into contact with the air, thereby achieving the effect of cooling the hollow microspheres faster, and solving the problem that the hollow microspheres are fixed in the discharge bin 6 after being made, difficult to dissipate heat, and the sieve plate cannot screen out the unqualified products that reach the specification due to the 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 knocking block 76 compresses the first spring 75 through the pressing of the inclined surface block 77 on the knocking block 76. When the stirring plate 74 continues to rotate to leave the inclined surface block 77, the knocking block 76 knocks on the inner wall of the discharge bin 6 in cooperation with the elastic force of the first spring 75, thereby vibrating the discharge bin 6 and turning the hollow microbeads in the discharge bin 6, solving the problem that the hollow microbeads are stacked together and the unqualified products on the upper layer cannot be screened out. ;

[0032] When the present embodiment is working, the motor 71 is started, the motor 71 drives the rotating shaft 72 to rotate, when the rotating shaft 72 rotates, the connecting rod 73 is driven to rotate, the connecting rod 73 drives the stirring plate 74 to rotate, the fired fly ash hollow microspheres are moved inside the discharge bin 6, the hollow microspheres roll under the stirring of the stirring plate 74, the reaction between the hollow microspheres and the air is accelerated, and the hollow microspheres are cooled faster, the stirring plate 74 drives the first spring 75 to rotate when rotating, and the first spring 75 drives the knocking block 76 to rotate together when rotating, because the discharge bin 6 is fixed, so 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 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 quickly, thereby turning over the hollow microbeads in the discharge bin 6.

[0033] See also Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, a crushing device for facilitating the crushing of unqualified products is provided below the discharge bin 6. The crushing device includes a crushing cylinder 81, a guide rod 82, a sliding rod 83, a convex block 84, a wave groove 85, a connecting rod 86, and a crushing block 87. The crushing cylinder 81 fits against the inner wall of the housing 1. A fixed block is fixed to the bottom end of the rotating shaft 72, and 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 cylinder 81. When the sliding rod 83 rotates, it drives the crushing cylinder 81 to rotate. The outer wall of the sliding rod 83 is slidably connected to the inner wall of the guide rod 82. When the guide rod 82 rotates, it drives the sliding rod 83 to rotate together. The convex block 84 is fixedly connected to the outer wall of the crushing cylinder 81. When the crushing cylinder 81 rotates, the convex block 84 on its outer wall also rotates together with the crushing cylinder 81. The wave groove 85 is opened on the inner wall of the housing 1. The outer wall of the convex block 84 fits against the inner wall of the wave groove 85. When the convex block 84 rotates, it slides along the wave groove 85, so that the convex block 84 moves up and down while rotating. Since the convex block 84 is fixedly connected to the outer wall of the crushing cylinder 81, the convex block 84 can drive the crushing cylinder 81 to slide up and down while rotating and moving up and down. The connecting rod 86 is fixedly connected to the side wall of the fixed block, and the crushing block 87 is hinged to the end of the connecting rod 86 away from the fixed block. While the crushing cylinder 81 rotates, it also slides up and down, 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 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 cooperation with the guide rod 82 and the sliding rod 83. The rotation of the crushing cylinder 81 drives the convex block 84 on its outer wall to slide on the inner wall of the wave groove 85, so that the convex block 84 moves up and down along the wave groove 85 while rotating, so that the crushing cylinder 81 not only rotates but also slides up and down, so that the unqualified products screened out can smoothly fall into the crushing cylinder 81 when they fall, solving the problem that the distance between the discharge bin 6 and the raw material tank 5 is too large, and the unqualified products are likely to fall out along the inner wall of the housing 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. When the crushing cylinder 81 slides up and down with the screened unqualified products, it impacts the crushing block 87. The pressure between the crushing block 87 and the crushing cylinder 81 crushes the unqualified products, so as to crush the unqualified products, which facilitates the unqualified products to fall into the raw material tank 5 from the crushing cylinder 81, solving the problem that the hollow microspheres that have been fired and formed are difficult to be fired again, and avoiding the problem that the round hollow microspheres are easy to roll out of the raw material tank 5.

[0034] The inner wall of the raw material tank 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 limiting rod 93, a powder scraping 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, it drives the connecting plate 91 to move downward. The hinged plate 92 is hinged to the bottom end of the connecting plate 91. When the connecting plate 91 moves downward, it drives the hinged plate 92 to move downward as well. The limiting rod 93 is fixedly connected to the outer wall of the support 3. A guiding strip is fixed on the upper surface of the raw material tank 5. The guiding strip penetrates through the powder scraping plate 94 and is slidably connected at the penetration point. A fixing plate is fixed on the inner wall of the powder scraping plate 94. When the hinged plate 92 moves downward, it pushes the fixing plate on the inner wall of the powder scraping plate 94 to slide towards the support 3. After the hinged plate 92 pushes the powder scraping plate 94 a certain distance, it inserts into the gap between the powder scraping plate 94 and the raw material tank 5, causing the hinged plate 92 to rotate. When the hinged plate 92 rotates, it further pushes the powder scraping plate 94 to slide towards the support 3, pushing the fly ash crushed by the crushing device towards the center, enabling the fly ash to enter the combustion unit more quickly for secondary processing. One end of the second spring 95 is fixedly connected to the side wall of the fixing plate. When the powder scraping plate 94 slides towards the support 3, the second spring 95 is compressed. The other end of the second spring 95 is fixedly connected to the end of the limiting rod 93 away from the support 3. The hinged rod 96 is hinged to the inner wall of the powder scraping plate 94. When the powder scraping plate 94 slides, it drives the hinged rod 96 to rotate. The grinding hammer 97 is fixedly connected to the end of the hinged rod 96 away from the powder scraping plate 94. The hinged rod 96 pushes the grinding hammer 97 to slide along the bottom surface of the raw material tank 5. The two groups of grinding hammers 97 collide with each other, further grinding the crushed hollow microspheres into powder. This auxiliary device drives the connecting plate 91 to slide up and down through the up and down sliding of the crushing cylinder 81. The connecting plate 91 drives the hinged plate 92 to move up and down, and cooperates with the fixing plate to push the powder scraping plate 94 towards the support 3, thereby pushing the powder generated by the crushed unqualified hollow microspheres towards the center, facilitating the fly ash to enter the combustion unit again for re-firing, and solving the problem that the fly ash after being crushed accumulates together and cannot enter the combustion unit by itself for re-firing; while pushing the fly ash towards the combustion unit, it drives the grinding hammer 97 to grind the fly ash through the hinged rod 96, thereby further crushing the large fragments of hollow microspheres that cannot pass through the feeding trough into powder, and solving the problem that the fragments of hollow microspheres are too large to be fully reused.

[0035] During the operation of this embodiment: 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 cylinder 81 to rotate. When the crushing cylinder 81 rotates, the convex block 84 on its outer wall also rotates together with the crushing cylinder 81. When the convex block 84 rotates, it slides along the wavy groove 85, so that the convex block 84 moves up and down while rotating. Since the convex block 84 is fixedly connected to the outer wall of the crushing cylinder 81, when the convex block 84 rotates and moves up and down, it can also drive the crushing cylinder 81 to slide up and down. The crushing cylinder 81 rotates while sliding up and down, 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 cylinder 81.

[0036] When the crushing cylinder 81 slides downward, it drives the connecting plate 91 to move downward, and also drives the hinged plate 92 to move downward. When the hinged plate 92 moves downward, it pushes the fixing plate on the inner wall of the powder scraping plate 94 to slide in the direction of the bracket 3. After the hinged plate 92 pushes the powder scraping plate 94 a certain distance, it inserts into the gap between the powder scraping plate 94 and the raw material tank 5, causing the hinged plate 92 to rotate. When the hinged plate 92 rotates, it further pushes the powder scraping plate 94 to slide in the direction of the bracket 3, pushing the fly ash crushed by the crushing device towards the center, so that the fly ash can enter the combustion unit more quickly for secondary processing. When the powder scraping plate 94 slides in the direction of the bracket 3, it compresses the second spring 95. At the same time, the powder scraping plate 94 drives the hinged rod 96 to rotate, and the hinged rod 96 pushes the grinding hammer 97 to slide along the bottom surface of the raw material tank 5. The two groups of grinding hammers 97 collide with each other, further grinding the crushed hollow microspheres into powder.
