The cement slurry mixing mechanism 5 is connected with the primary mixing pipeline 2 through a combination of a double-main-cylinder pumping mechanism 53 and a pumping switching mechanism 54, cement slurry is continuously injected into the primary mixing pipeline 2, the double-main-cylinder pumping mechanism 53 and the pumping switching mechanism 54 are not important for the protection of the invention, the specific technical scheme is shown in patent ZL201420558880.X and ZL201220512410.0, and the double-main-cylinder pumping mechanism 53 and the pumping switching mechanism 54 jointly form a cement slurry injection mechanism.

Foam and cement paste enter the conveyor 1 that preliminary mixing pipeline 2 rear end is connected after preliminary mixing in preliminary mixing pipeline 2, conveyor 1 not only transmits the foaming concrete, can further mix the foaming concrete simultaneously for the foam distributes more evenly in the concrete. As shown in fig. 5-6, the conveying device 1 includes a conveying pipe 11 and a mixing shaft 12 disposed inside the conveying pipe 11, the conveying pipe 11 is composed of a pipe body 111, and a conveying feed port 112 and a conveying discharge port 113 fixedly mounted at two ends of the pipe body 111, the conveying feed port 112 and the conveying discharge port 113 are detachably connected with the pipe body 111 through a conveying pipe clamp 114 respectively, when the pipe body 111 fails or the mixing roller 12 is damaged, the pipe body 111 can be detached to replace the internal device, and in addition, the conveying pipe clamp 114 also has a positioning function. Further, the discharge outlet 113 is further provided with a discharge outlet 115, and the discharge outlet 115 is mainly used for discharging the surplus materials in the conveying pipe, and the surplus materials in the pipe body 111 are discharged after the pumping work is completed, so that the maintenance and long-term use of the equipment are facilitated. The surface of the mixing shaft 12 is provided with the blades 13, and the transmission path of the foaming concrete in the conveying pipe 11 can be changed through the arrangement of the blades 13, so that the foaming concrete is mixed at different angles, and further, the foam distribution is more uniform. Specifically, the mixing shaft 12 is provided with a plurality of vane wheels, each vane wheel comprises three evenly distributed vanes 13, an included angle of 45-75 degrees is formed between each vane 13 and the radial plane of the mixing shaft 12, in this embodiment, the included angle between each vane 13 and the radial plane of the mixing shaft 12 is uniformly 60 degrees, and the angle vanes 13 can optimize the foam mixing effect while ensuring the advancing speed of the foam concrete. The blades 13 between two adjacent wheels are staggered, the corresponding blades 13 form included angles with the radial plane in different directions, and the corresponding blades 13 between two wheels of the alternate wheel are arranged in parallel. Adjacent blade wheel staggered arrangement can ensure the advancing speed of the foaming concrete, avoid blocking the conveying pipe 11 because of too big resistance, the blade 13 is oriented differently and can make the foaming concrete by the blade wheel of another angle to carry out the opposite direction mixing after passing a round of blade wheel, just because the foaming concrete is by the endless switching-over mixing in the conveying pipe 11, can make the foam distribute fully evenly in the foaming concrete, avoid mixing shaft 12 to rotate simultaneously.
In order to reduce the broken bubble of foam, the mixing shaft 12 is movably arranged in the conveying pipe 11, specifically, the mixing shaft 12 can be freely placed in the conveying pipe 11, no connection exists between the mixing shaft 12 and the conveying pipe 11, along with the pushing of the foamed concrete, as the blades 13 with different directions are alternately arranged on the mixing shaft 12, the stress of the mixing shaft 12 is balanced, and the mixing shaft 12 cannot rotate at a higher speed in the conveying pipe 11, so that the cutting of the foamed concrete is avoided, and the damage to the foam in the foamed concrete is reduced. At the same time, the mixing shaft 12 can be moved in position with the internal concrete density distribution to promote uniform mixing of the foamed concrete. Another possible solution is that the mixing shaft 12 can be freely rotatably connected in the conveying pipe 11, two ends of the mixing shaft 12 are connected with two ends of the conveying pipe 11 through bearings, and the mixing shaft 12 can be well positioned, so that noise generated when the mixing shaft 12 knocks the conveying pipe 11 due to too severe movement of the mixing shaft 12 in the conveying pipe 11 is avoided.
Because the mixing shaft 12 carrying the blades 13 is arranged in the conveying device 1, a certain resistance is formed to the conveying of the foamed concrete, on the other hand, the density distribution of the foamed concrete which is primarily mixed is also relatively uneven, so that the foamed concrete can not be smoothly guided into the conveying device 1 in time in the primary mixing pipeline 2, the pressure in the primary mixing pipeline 2 can be excessively high so that the formed foam is broken, the formed foamed concrete after the foam is reduced can not meet the requirement, and the pressure in the primary mixing pipeline 2 can be reduced by arranging the buffer cylinder 3 communicated with the primary mixing pipeline 2 so as to reduce the damage to the foam. As shown in fig. 7, the buffer cylinder 3 is composed of a cylinder body 30, a first end cap 31 and a second end cap 32 fixedly capped at both ends of the cylinder body, and end cap sealing rings 33 are respectively arranged between the cylinder body 30 and the first end cap 31 and between the cylinder body 30 and the second end cap 32 so as to prevent the medium in the cylinder body 30 from being extruded from the edges of the end caps. The piston 34 is arranged in the cylinder body 30, the piston 34 is a floating light piston, the inner wall of the cylinder body 30 is made of wear-resistant steel material through finish machining to form a smooth wear-resistant surface, and the surface of the piston 34 is wrapped with polyurethane material, particularly the contact part of the piston 34 and the cylinder body 30, so that the piston 34 is wear-resistant and antifouling. The piston 34 is arranged between the first end cover 31 and the second end cover 32 and is enclosed with the first end cover 31 to form a gas chamber 35 storing buffer gas, the buffer gas can be nitrogen with stability, the piston 34 and the second end cover 32 are enclosed to form a solid-liquid chamber 36 for buffering foaming concrete, a central sealing ring 37 is arranged between the piston 34 and the cylinder body 30, and the central sealing ring 37 can effectively ensure complete isolation between the gas chamber 35 and the solid-liquid chamber 36. The first end cap 31 is provided with a gas valve 38, the gas valve 38 is mainly used for injecting nitrogen into the gas chamber 35, the gas valve 38 can be a one-way valve, and the gas is allowed to be injected to avoid gas output, so that the preset pressure is kept in the gas chamber 35. The second end cover 32 is provided with a buffer feed port 39, and the buffer cylinder 3 is inserted into the side wall of the primary mixing pipeline 2 through the buffer feed port 39. The side wall 2 of the primary mixing pipe is provided with a branch pipe 21, and a buffer feed port 39 and the branch pipe 21 are mutually sleeved and locked through a clamp 22. At ordinary times, the piston 34 in the cylinder 30 is often located at the bottom of the cylinder 30 under the action of nitrogen with a certain preset pressure, and when the pressure in the primary mixing pipeline 2 is too high to exceed the preset pressure in the gas chamber 35, the foamed concrete flows into the cylinder from the buffer feed port 39 through the branch pipe 21 and pushes the piston 34 to slowly rise. During the rising process, the nitrogen in the gas chamber 35 is compressed and the excess pressure in the foamed concrete will exist in the form of the internal energy of the gas. When the pressure in the primary mixing pipe 2 is reduced and is lower than the pressure in the gas chamber 35, the piston 34 is reversed and slowly pressed down, the foamed concrete in the solid-liquid chamber 36 is extruded back into the primary mixing pipe 2 and enters the conveying device 1 in the pressing process, and the nitrogen pressure in the gas chamber 35 is gradually reduced to an initial state to wait for the next buffer protection of the foamed concrete.
Further, a safety valve 311 can be further arranged on the first end cover 31, the safety valve 311 mainly performs overpressure protection on the air cylinder 30, the safety valve 311 can be an electromagnetic valve controlled to be opened and closed by a single chip microcomputer 312, a pressure sensor 313 is arranged in the air chamber 35, the pressure sensor 313 is connected with the single chip microcomputer 312 for controlling the safety valve 311 in a signal mode, when the pressure sensor 313 senses that the pressure in the air chamber 35 is greater than a certain threshold value, the single chip microcomputer 312 controls the electromagnetic valve to be opened, the air chamber 35 is subjected to pressure relief protection, meanwhile, the whole foaming concrete conveying buffer device is stopped, and after faults are removed and the air chamber 35 is subjected to pre-pressure setting again through the air valve 38, the whole device is allowed to continue to operate again.
When the device operates, the method comprises the following steps:
step one: a large amount of foam generated by the foam generating mechanism 4 and cement slurry manufactured by the cement slurry mixing mechanism 5 are pumped into the primary mixing pipeline 2 at the same time to be mixed to form foam concrete with uneven micro-bubble distribution;
step two: the foaming concrete enters the conveying device 1 again, and is conveyed while being further uniformly mixed through a mixing shaft 12 and a blade 13 on the mixing shaft 12 which are movably arranged in a conveying pipe 11, and is output through a foaming concrete output mechanism 6;
step three: when the internal pressure of the primary mixing pipeline 2 is too high, the foamed concrete is pressed into a buffer cylinder 3 directly connected with the primary pipeline 2 for buffering, so that the influence on the product quality caused by foam breaking of the foamed concrete due to high pressure can be avoided;
step four: the pressure in the primary mixing pipeline 2 is restored, and the foamed concrete in the buffer cylinder 3 is pressed into the primary mixing pipeline 2 again under the action of the pressure in the buffer cylinder 3 and enters the conveying device 1 for transportation and further mixing.
