Description

Technical Field

[0002] Fly ash is the fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged by coal-fired power plants. With the development of the power industry, the fly ash emissions from coal-fired power plants have increased year by year, becoming one of the largest industrial waste residues in my country. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river siltation, and the toxic chemicals in it will also cause harm to humans and organisms. However, fly ash can be used as a resource, such as as an admixture for concrete.

[0003] There are several problems with the existing fly ash concrete carbonization performance improvement equipment: 1. Processing fly ash in humid weather will cause the fly ash to become damp, thereby affecting the subsequent hydration reaction of the concrete and reducing the carbonization performance; 2. If the fly ash particles are coarse, when it participates in the hydration reaction, the hydration products generated are not sufficient to fill the adaptive pores, thereby affecting the concrete's anti-carbonation ability.

[0050] The outside of the feed pipe 11 is fixedly connected with a fixing rod 105, and one end of the fixing rod 105 away from the feed pipe 11 is fixedly connected with a limiting ring 104. The inner side of the limiting ring 104 is slidably adapted with a small heater 102. The small heater 102 is inserted into the outside of the feed pipe 11 and extends into the inside thereof. The outer side of the small heater 102 is fixedly connected with an elastic bar 103. In addition, as the sliding rod 12 moves downward, its bottom will squeeze the pressure cover 16, causing the pressure cover 16 to compress the reset pad 101 fixed at its bottom and move downward, and then the inner wall of the pressure cover 16 will hit the inner end of the small heater 102, wherein the contact portion between the pressure cover 16 and the small heater 102 is a curved surface, causing the small heater 102 to extend outward along the limiting ring 104 and pull The elastic bar 103 is extended and fixedly connected to the outer side thereof, thereby playing the role of closing and protecting the small heater 102, wherein the elastic bar 103 plays the role of resetting the small heater 102, and the end of the elastic bar 103 away from the small heater 102 is fixedly connected to the outer side of the feeding pipe 11, the inner side of the feeding pipe 11 is fixedly connected with an inner tube 106, the inner part of the inner tube 106 is fixedly connected with a central axis 107, the outer side of the central axis 107 is rotatably connected with a screen 108, the outer side of the screen 108 is fixedly connected with a compensation rod 109, the upper and lower sides of the compensation rod 109 are fixedly connected with a baffle 100, the end of the baffle 100 away from the compensation rod 109 is fixedly connected to the inner tube 106, and the bottom of the compensation rod 109 is fixedly connected with a universal seat 111.

[0051] The bottom of the No. 1 universal seat 111 is fixedly connected to a hydraulic rod 112, and the bottom of the hydraulic rod 112 is fixedly connected to a strap 113, which is fixedly connected to the inner side of the inner tube 106. The side of the screen 108 away from the No. 1 compensation rod 109 is fixedly connected to the No. 2 compensation rod 114, and the upper and lower sides of the No. 2 compensation rod 114 are fixedly connected to the No. 2 blocking plate 115. The end of the No. 2 blocking plate 115 away from the No. 2 compensation rod 114 is fixedly connected to the inner tube 106. The bottom of the rod 114 is fixedly connected with a second universal seat 116, the bottom of the second universal seat 116 is fixedly connected with a telescopic rod 117, the bottom of the telescopic rod 117 is fixedly connected with the strap 113, the bottom of the second compensation rod 114 and the outer side of the telescopic rod 117 are fixedly connected with a damper 118, by throwing fly ash from the top of the feed pipe 11, the fly ash will enter the inner tube 106 and accumulate on the screen 108, then start the hydraulic rod 112, so that The No. 1 compensation rod 109 connected to its top through the No. 1 universal seat 111 will move upward, however, the other end of the No. 1 compensation rod 109 is connected to the screen 108, and the screen 108 is deflected through the central axis 107. Therefore, with the extension and contraction of the hydraulic rod 112, the two sides of the screen 108 will swing up and down, and the No. 2 compensation rod 114 fixedly connected to the other side of the screen 108 will move in the opposite direction between the No. 1 compensation rod 109, causing the telescopic rod 117 connected to the No. 2 compensation rod 114 through the No. 2 universal seat 116 to also telescope in the opposite direction between the hydraulic rod 112, thereby balancing the force of the screen 108 during the swinging process and preventing the fly ash from being lifted upward due to excessive swinging amplitude. The small heater 102 will heat and dry the fly ash on the screen 108 through the inner tube 106, thereby preventing the mixed moisture from affecting the subsequent hydration reaction.

[0052] like Figure 8 , Fig. 9 and Fig.10As shown, the fine grinding mechanism 3 includes a transition tube 31, which is fixedly connected to the bottom of the feed tube 11, and a notch 32 is opened on the top of the transition tube 31. A toughness strip 33 is fixedly connected to the top of the inner cavity of the transition tube 31, and a gold foil plate 34 is fixedly connected to the bottom end of the toughness strip 33. A grinding disc 35 is arranged below the gold foil plate 34, and a motor 36 is connected to the bottom of the grinding disc 35 through a coupling. A bearing 37 is extruded and adapted on the outer side of the output end of the motor 36, and the side of the bearing 37 away from the motor 36 is extruded and adapted on the inner side of the transition tube 31, and a ring cover 38 is fixedly connected to the bottom of the inner cavity of the transition tube 31, and a receiving bucket 39 is fixedly connected to the bottom of the transition tube 31. The receiving bucket 39 The bottom of the pressure hood 16 is fixedly connected with an intermediate tube 30. As the pressure hood 16 is squeezed downward by the slide rod 12, the reset pad 101 fixedly connected to the bottom of the pressure hood 16 will be compressed, wherein the reset pad 101 is elastic and plays a role in resetting the pressure hood 16. At the same time, the insertion rod 17 fixedly connected to the bottom of the pressure hood 16 will carry the vibration block 18 into the interior of the transition pipe 31 and hit the gold foil plate 34. The role of the gold foil plate 34 is similar to that of a gong, and it has high vibration. The gold foil plate 34 that is hit will vibrate and shake off the fly ash adhered and accumulated on its surface, and the shaken fly ash will stay on the grinding disc 35.

[0053] The outer side of the grinding disc 35 is fixedly connected with a No. 1 rolling tooth 301, and the side of the No. 1 rolling tooth 301 away from the grinding disc 35 is slidably adapted with a No. 2 rolling tooth 302, and the No. 2 rolling tooth 302 is inserted into the inner side of the transition tube 31 and extends to its outside, and the outer side of the No. 2 rolling tooth 302 is fixedly connected with an upper inclined block 303, and the top of the upper inclined block 303 is squeezed and adapted with the lower pressure plate 10, and the inner side of the transition tube 31 is fixedly connected with a reset bar 304, and the end of the reset bar 304 away from the transition tube 31 is fixedly connected with a top fixing plate 305, and the top fixing plate 305 is fixedly connected to the top of the No. 2 rolling tooth 302. In addition, as the insertion rod 17 moves downward, the sleeve plate 19 fixedly connected to the outer side thereof will move downward with the lower pressure plate 10 and hit the upper inclined block 303. The contact surface between the lower pressing plate 10 and the upper inclined block 303 is an inclined surface, and the upper inclined block 303 that is hit will insert the No. 2 rolling tooth 302 into the interior of the transition pipe 31 and match the No. 1 rolling tooth 301. The reset bar 304 connected to the No. 2 rolling tooth 302 through the top fixing plate 305 is tough, which plays a role in resetting the No. 2 rolling tooth 302. Then the motor 36 is started, so that the grinding disc 35 connected to the output end through the coupling will rotate with the No. 1 rolling tooth 301, and then the fly ash accumulated on the grinding disc 35 will move to the meshing position of the No. 1 rolling tooth 301 and the No. 2 rolling tooth 302 due to the centrifugal force, so as to grind the fly ash, increase its specific surface area, and improve its activity. The ground fly ash can participate in the hydration reaction faster in the concrete, generate more hydration products, fill the pores, and enhance the concrete's anti-carbonation ability.

[0054] like Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the mixing mechanism 4 includes a conical tube 41, the top of the conical tube 41 is fixedly connected to the intermediate tube 30, the bottom of the conical tube 41 is fixedly connected to a transmission tube 42, the bottom of the transmission tube 42 is fixedly connected to a base frame 43, a connection frame 46 is provided below the transmission tube 42, the inside of the transmission tube 42 is rotatably connected to a spiral auger 44, the outer end of the spiral auger 44 is connected to a driver 45 through a coupling, the top of the transmission tube 42 is fixedly connected to a material frame 404, the inner side of the material frame 404 is symmetrically connected to a support 403, and the inside of the support 403 is rotatably connected to There is a flip door 402, a vertical rod 401 is arranged on the top of the flip door 402, a cross bar 40 is fixedly connected to the top of the vertical rod 401, the cross bar 40 is slidably adapted to the outside of the conical tube 41, the end of the cross bar 40 away from the vertical rod 401 is fixedly connected to the inner tube 47, the outer side of the inner tube 47 is fixedly connected to the slider 48, the end of the slider 48 away from the inner tube 47 is slidably adapted to the vertical rail 49, the vertical rail 49 is fixedly connected to the inner side of the conical tube 41, and the fly ash after secondary finishing will enter the receiving bucket 39 along the inner wall of the transition tube 31 until it passes through the transition tube 31 again. The fly ash is discharged from the receiving bucket 39 and enters the middle pipe 30. Then, the fly ash discharged from the middle pipe 30 enters the conical pipe 41 and continues to move downward along the inner pipe 47 fixedly connected to the inner side of the conical pipe 41, and finally enters the transmission pipe 42. At this time, the driver 45 is started, so that the spiral auger 44 connected to its output end through the coupling will rotate and transport the fly ash forward, wherein the fly ash will continuously impact the inner pipe 47, causing the inner pipe 47 to move downward along the vertical rail 49 through the slider 48 due to the impact force. The horizontal bar 40 fixedly connected to the top of the inner tube 47 will move downward with the vertical bar 401 and hit the flip door 402, and the flip door 402 that is hit will deflect downward, causing the mineral admixture that initially stays on the flip door 402 to enter the transmission pipe 42 little by little, and be mixed with the fly ash through the spiral auger 44, and finally enter the connection frame 46 along the transmission pipe 42, so that the mineral admixture has potential gelling properties, and is hydrated with cement and fly ash to fill the pores of the concrete. The silica fume particles are extremely fine and have a large specific surface area, which can significantly improve the density of the concrete.

[0055] When the present invention is in use: first, fly ash is thrown into the top of the feed pipe 11, and then the fly ash enters the inner tube 106 and accumulates on the screen 108. At this time, the hydraulic rod 112 is started, so that the No. 1 compensation rod 109 connected to the top through the No. 1 universal seat 111 will move upward. However, the other end of the No. 1 compensation rod 109 is connected to the screen 108, and the screen 108 is deflected through the central axis 107. Therefore, with the extension and contraction of the hydraulic rod 112, the two sides of the screen 108 will swing up and down. At the same time, the small heater 102 will heat and dry the fly ash on the screen 108 through the inner tube 106. When the fly ash is completely added and enters the fine grinding mechanism 3, the slide bar 12 is manually moved downward so that the cleaning brush 13 connected to the inner end will move downward and clean the inner wall of the feed pipe 11. At the same time, as the slide bar 12 moves downward, its bottom will squeeze the pressure cover 16, causing the pressure cover 16 to compress the reset pad 101 fixed at its bottom and move downward. Then the inner wall of the pressure cover 16 will hit the inner end of the small heater 102, causing the small heater 102 to extend outward along the limiting ring 104 and stretch the elastic strip 103 fixedly connected to its outer side, so as to realize the closing and protection of the small heater 102.

[0056] As the pressure cover 16 is pressed downward by the slide bar 12, the insertion rod 17 fixedly connected to the bottom of the pressure cover 16 will extend into the interior of the transition pipe 31 with the vibration block 18 and hit the gold foil plate 34. The gold foil plate 34 that is hit will vibrate and shake off the fly ash adhered and accumulated on its surface. The shaken fly ash will stay on the grinding disc 35. In addition, the downward movement of the insertion rod 17 causes the sleeve plate 19 fixedly connected to its outer side to move downward with the lower pressure plate 10. The upper inclined block 303 will be hit, and the hit upper inclined block 303 will be inserted into the interior of the transition pipe 31 with the second rolling tooth 302 and close to the first rolling tooth 301. At this time, the motor 36 is started, so that the grinding disc 35 connected to its output end through the coupling will rotate with the first rolling tooth 301, and then the fly ash accumulated on the grinding disc 35 will move to the meshing position of the first rolling tooth 301 and the second rolling tooth 302 due to the centrifugal force, so as to realize the secondary finishing of the fly ash.

[0057] After secondary finishing, the fly ash will enter the receiving bucket 39 along the inner wall of the transition pipe 31, until it is discharged from the receiving bucket 39 and enters the intermediate pipe 30. Then, the fly ash discharged from the intermediate pipe 30 will enter the tapered pipe 41, and continue to move downward along the inner pipe 47 fixedly connected to the inner side of the tapered pipe 41, and finally enter the transmission pipe 42. At this time, the driver 45 is started, so that the spiral auger 44 connected to its output end through the coupling will rotate, and transport the fly ash forward until it enters the connecting frame 46.
