Description

Technical Field

[0001] The present invention relates to the technical field of concrete, and specifically relates to a production device and method for concrete. Background Art

[0002] Fly ash is the fine ash captured from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. With the development of the power industry, the discharge of fly ash from coal-fired power plants has been increasing year by year, becoming one of the industrial waste residues with a large discharge in China at present. 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 chemical substances in it will also harm humans and organisms. However, fly ash can be resourcefully utilized, such as being used as a admixture in concrete, etc.

[0003] The existing equipment for improving the carbonation performance of fly ash concrete has the following problems: 1. Processing fly ash in humid weather will cause the fly ash to be affected by moisture, which will affect the subsequent hydration reaction of the concrete and reduce the carbonation performance; 2. If the particles of fly ash are relatively coarse, when it participates in the hydration reaction, the generated hydration products are not enough to fill and adapt to the pores, thus affecting the carbonation resistance of the concrete.

[0027] 2. The fly ash accumulated on the grinding disc will move to the meshing position of the first and second rolling teeth due to centrifugal force, thereby grinding the fly ash to increase its specific surface area and improve its activity. The ground fly ash can participate in the hydration reaction faster in concrete, generate more hydration products, fill pores, and enhance the concrete's anti-carbonation ability.

[0028] 3. The flip door that is hit will deflect downward, causing the mineral admixture that originally stayed on the flip door to enter the transmission pipe little by little, and be mixed with the fly ash through the spiral auger, and finally enter the connecting frame along the transmission pipe, thereby utilizing the potential gelling properties of the mineral admixture, hydrating together with cement and fly ash, and filling the pores of the concrete.

It should be understood that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0046] A fine grinding mechanism 3 for finely grinding fly ash concrete, and a bracket 2 is fixedly connected to the outside of the fine grinding mechanism 3;

[0047] An admixture mechanism 4 for improving the density of fly ash concrete;

[0048] The drying mechanism 1 is fixedly installed on the top of the fine grinding mechanism 3, and the bottom of the fine grinding mechanism 3 is fixedly connected to the admixture mechanism 4.

[0049] Among them, the drying mechanism 1 includes a feed pipe 11, a sliding rod 12 is slidably fitted on the outside of the feed pipe 11, a cleaning brush 13 is fixedly connected to the inner end of the sliding rod 12. When the fly ash is completely put in and all enters the fine grinding mechanism 3, manually move the sliding rod 12 downward, so that the cleaning brush 13 connected to its inner end will move downward and clean the inner wall of the feed pipe 11, and at the same time sweep the residual fly ash into the fine grinding mechanism 3 to avoid waste and dust interfering with the line of sight. The cleaning brush 13 is slidably fitted inside the feed pipe 11, leak-proof pads 14 are fixedly connected to both the upper and lower sides of the sliding rod 12, and the end of the leak-proof pad 14 away from the sliding rod 12 is fixedly connected to the feed pipe 11. Telescopic rings 15 are symmetrically connected to both ends of the sliding rod 12. A pressure-receiving cover 16 is arranged below the sliding rod 12. Reset pads 101 are fixedly connected to both the upper and lower sides of the pressure-receiving cover 16, and the bottom end of the reset pad 101 is fixedly connected to the feed pipe 11. A through rod 17 is fixedly connected to the bottom of the pressure-receiving cover 16, a vibration block 18 is fixedly connected to the bottom end of the through rod 17, a sleeve plate 19 is fixedly connected to the outside of the through rod 17, and a lower pressing plate 10 is fixedly connected to the bottom of the sleeve plate 19.

[0050] A fixed rod 105 is fixedly connected to the outside of the feed pipe 11. One end of the fixed rod 105 away from the feed pipe 11 is fixedly connected to a limit ring 104. A small heater 102 is slidably fitted inside the limit ring 104. The small heater 102 penetrates through the outside of the feed pipe 11 and extends into its interior. A spring strip 103 is fixedly connected to the outside of the small heater 102. Additionally, as the sliding rod 12 moves downward, the bottom of it will squeeze the pressure-receiving cover 16, causing the pressure-receiving cover 16 to compress the reset pad 101 fixed to its bottom and move downward. Immediately afterwards, the inner wall of the pressure-receiving cover 16 will impact the inner end of the small heater 102. The part where the pressure-receiving cover 16 contacts the small heater 102 is a curved surface, causing the small heater 102 to extend outward along the limit ring 104 and stretch the spring strip 103 fixedly connected to its outside, thereby playing a role in closing and protecting the small heater 102. Among them, the spring strip 103 plays a role in resetting the small heater 102. One end of the spring strip 103 away from the small heater 102 is fixedly connected to the outside of the feed pipe 11. An inner pipe 106 is fixedly connected to the inside of the feed pipe 11. A central shaft 107 is fixedly connected to the inside of the inner pipe 106. A sieve 108 is rotatably connected to the outside of the central shaft 107. A first compensation rod 109 is fixedly connected to the outside of the sieve 108. First blocking pieces 100 are fixedly connected to both the upper and lower sides of the first compensation rod 109. One end of the first blocking piece 100 away from the first compensation rod 109 is fixedly connected to the inner pipe 106. A first universal joint 111 is fixedly connected to the bottom of the first compensation rod 109.

[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 , Figure 9 and Figure 10As shown in the figure, the fine grinding mechanism 3 includes a transition pipe 31. The transition pipe 31 is fixedly connected to the bottom of the feeding pipe 11. An opening 32 is provided at the top of the transition pipe 31. A resilient strip 33 is fixedly connected to the top of the inner cavity of the transition pipe 31. The bottom end of the resilient strip 33 is fixedly connected to a gold foil disc 34. A grinding disc 35 is arranged below the gold foil disc 34. The bottom of the grinding disc 35 is connected to a motor 36 through a coupling. The outer side of the output end of the motor 36 is extrusion-fitted with a bearing 37. The side of the bearing 37 away from the motor 36 is extrusion-fitted inside the transition pipe 31. A ring cover 38 is fixedly connected to the bottom of the inner cavity of the transition pipe 31. A receiving hopper 39 is fixedly connected to the bottom of the transition pipe 31. The bottom of the receiving hopper 39 is fixedly connected to an intermediate pipe 30. As the pressure-receiving cover 16 is downwardly extruded by the sliding rod 12, the reset pad 101 fixedly connected to the bottom of the pressure-receiving cover 16 will be compressed. The reset pad 101 is elastic and functions to reset the pressure-receiving cover 16. At the same time, the insertion rod 17 fixedly connected to the bottom of the pressure-receiving cover 16 will drive the vibration block 18 to extend into the interior of the transition pipe 31 and impact the gold foil disc 34. The gold foil disc 34 functions similar to a gong and has high vibration properties. The impacted gold foil disc 34 will vibrate and shake off the fly ash adhering and accumulating on its surface. The shaken-off fly ash will stay on the grinding disc 35.

[0053] A first rolling tooth 301 is fixedly connected to the outer side of a grinding disc 35. A second rolling tooth 302 is slidably fitted to the side of the first rolling tooth 301 away from the grinding disc 35. The second rolling tooth 302 penetrates through the inside of a transition pipe 31 and extends to the outside thereof. An upper inclined block 303 is fixedly connected to the outer side of the second rolling tooth 302. The top of the upper inclined block 303 is in pressing fit with a lower pressing plate 10. A reset strip 304 is fixedly connected to the inside of the transition pipe 31. One end of the reset strip 304 away from the transition pipe 31 is fixedly connected to a top fixing plate 305. The top fixing plate 305 is fixedly connected to the top of the second rolling tooth 302. Additionally, as an insertion rod 17 moves downward, a sleeve plate 19 fixedly connected to the outside thereof will drive the lower pressing plate 10 to move downward and strike the upper inclined block 303. The contact surfaces between the lower pressing plate 10 and the upper inclined block 303 are all inclined surfaces. The struck upper inclined block 303 will drive the second rolling tooth 302 to insert into the inside of the transition pipe 31 and be adapted to the first rolling tooth 301. The reset strip 304 connected to the second rolling tooth 302 through the top fixing plate 305 is resilient and functions to reset the second rolling tooth 302. Then, a motor 36 is started, and the grinding disc 35 connected to the output end thereof through a coupling will drive the first rolling tooth 301 to rotate. Subsequently, the fly ash accumulated on the grinding disc 35 will move to the meshing part of the first rolling tooth 301 and the second rolling tooth 302 due to centrifugal force, thereby grinding the fly ash to increase its specific surface area and improve its activity. The ground fly ash can participate in the hydration reaction faster in concrete, generate more hydration products, fill pores, and enhance the carbonation resistance of the concrete.

[0054] Such as Figure 11 , Figure 12 , Figure 13 and Figure 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] The fly ash after secondary finishing will enter the receiving hopper 39 along the inner wall of the transition pipe 31 until it is discharged from the receiving hopper 39 and enters the intermediate pipe 30. Subsequently, the fly ash discharged from the intermediate pipe 30 will enter the conical pipe 41 and continue to move downward along the internal pipe 47 fixedly connected to the inner side of the conical pipe 41, and finally enter the transmission pipe 42. At this time, the driver 45 is started, so that the screw auger 44 connected to its output end through a coupling will rotate and convey the fly ash forward until it enters the receiving frame 46.

[0058] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Those of ordinary skill in the art, starting from the above concepts and without creative labor, all kinds of transformations made fall within the scope of protection of the present invention.
