Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete block processing, in particular to a manufacturing method of environment-friendly aerated concrete block and a special mixer. BACKGROUND

[0002] Concrete is one of the most important civil engineering materials in the present age, which is a kind of artificial stone made of cementitious materials, granular aggregates, water, and, if necessary, additives and admixtures, by a certain proportion, uniform stirring, compaction, curing and hardening. Concrete has the characteristics of abundant raw materials, low price and simple production process, so its use is increasing. At the same time, concrete also has high compressive strength, good durability, wide strength grade range and other characteristics. These characteristics make it widely used not only in various civil engineering, but also in shipbuilding industry, mechanical industry, ocean development, geothermal engineering, etc. Aerated concrete block is a type of concrete, which has the advantages of light weight, good thermal insulation performance, high strength, good seismic performance, good processing performance, high temperature resistance, good sound insulation performance and other advantages, and is gradually popularized to replace traditional concrete.

[0003] In the prior art, the traditional aerated concrete block needs to use a mixer to mix the materials during production. Since lime needs to be added to the aerated concrete block, high temperature will be generated in the mixer during the mixing of raw materials. The traditional mixer cannot collect the heat, and most of the heat is directly discharged, which is not environmentally friendly and causes waste of heat. In addition, the traditional mixing method is single, and the angle of the stirring blade cannot be adjusted, resulting in poor mixing effect of the raw materials. SUMMARY

[0004] The purpose of the present application is to solve the problems existing in the prior art, and to provide a manufacturing method of environment-friendly aerated concrete block and a special mixer. By setting the stirring mechanism and the adjusting mechanism, the stirring range of the stirring blade can be expanded, so that the materials can be stirred more fully. By setting the collecting mechanism, the heat and water vapor generated during the stirring process can be reasonably utilized, which can effectively avoid the waste of energy and make the device more environmentally friendly.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0011] S5, steam curing, the block mold and the material are put into the steam curing bin, and the high temperature steam is used for steam curing;

[0012] The mixer used in the above-mentioned aerated concrete block manufacturing method comprises a mixer body, a fixed pipe fixedly connected to the inner top of the mixer body, a stirring mechanism arranged in the mixer body and used for stirring the material, a drive rod rotatably connected to the inner bottom of the mixer body, three fourth fixed blocks fixedly connected to the two end side walls of the drive rod, a plurality of stirring blades rotatably connected to the fourth fixed blocks, a third fixed block fixedly connected to the opposite side wall of each of the plurality of stirring blades, a linkage rod rotatably connected between every two third fixed blocks, a sleeve ring slidably sleeved on the fixed pipe, an adjusting mechanism arranged on the sleeve ring and used for adjusting the inclination angle of the stirring blade, a first fixed block fixedly connected to the two end side walls of the sleeve ring, a rotating rod rotatably connected to each of the two first fixed blocks, a second fixed block rotatably connected to the end of the rotating rod away from the first fixed block, and the second fixed block fixedly connected to the upper two stirring blades, respectively, a base fixedly connected to the lower end of the mixer body, a driving mechanism arranged in the base and used for driving the stirring mechanism, and a collecting mechanism arranged in the fixed pipe and used for collecting the steam generated in the mixing process.

[0013] Preferably, the driving mechanism comprises a motor fixedly connected to the inner bottom of the base, and the output shaft of the motor is fixedly connected to the lower end of the drive rod.

[0014] Preferably, the collecting mechanism comprises a permanent magnet ring fixedly connected to the inner wall of the fixed pipe, a magnetic piston slidably connected in the fixed pipe, the magnetic piston matched with the permanent magnet ring, an exhaust pipe communicated with the side wall of the fixed pipe, the end of the exhaust pipe away from the fixed pipe penetrating through the side wall of the mixer body and connected with a steam curing chamber, and a temperature control device arranged in the steam curing chamber.

[0015] Preferably, the lower end of the magnetic piston is rotatably connected with a support rod, the two end side walls of the support rod are fixedly connected with horizontal rods, the ends of the two horizontal rods are fixedly connected with vertical rods, and the upper ends of the two vertical rods are fixedly connected to the lower end of the sleeve ring.

[0016] Preferably, the upper end of the mixer body is provided with a feed inlet, and a sealing cover is provided at the feed inlet. A discharge outlet is provided on one side wall of the mixer body, and a valve is provided on the discharge outlet.

[0017] Preferably, a water pump is provided on the side wall of the mixer body.

[0018] Preferably, a feeder is installed on the side wall of the mixer body, and the feeder is connected to the mixer body through a feed pipe.

[0019] Compared with the prior art, the beneficial effects of this invention are as follows:

[0020] 1. By setting up a stirring mechanism and an adjusting mechanism, after the material enters the main body of the mixer, the output shaft of the drive motor rotates, which in turn drives the drive rod to rotate. The rotation of the drive rod drives the fourth fixed block and the stirring blades on it to rotate. During the stirring process, lime powder is intermittently and quantitatively fed into the main body of the mixer through the feeder. When lime powder is added, the lime powder and water produce a high-temperature reaction in the main body of the mixer, which raises the water temperature and produces water vapor. As the steam accumulates in the main body of the mixer, the pressure inside the main body of the mixer increases, and the steam pushes the magnetic piston to move upward. During the upward movement of the magnetic piston, it carries... The moving support rod, horizontal rod, and vertical rod move upward, causing the collar to move upward, which in turn drives the rotating rod to rotate. Under the pull of the rotating rod and the linkage rod, the angles of multiple stirring blades change. When the magnetic piston moves upward above the exhaust pipe, steam is discharged from the exhaust pipe. After the steam in the main body of the mixer is gradually discharged, the magnetic piston moves downward to reset under the attraction of the permanent magnet ring, causing the collar to reset. When the collar resets, it pushes the rotating rod to reset, causing the tilt angle of the stirring blades to change again. This stirring method has an ingenious structure that can expand the stirring range of the stirring blades, thereby enabling more thorough stirring of materials.

[0021] 2. By setting up a collection mechanism, when the feeder puts lime powder into the mixer body, the lime powder reacts with the water inside the mixer body, causing water vapor to be generated inside the mixer body. After the water vapor accumulates to a certain extent, the pressure inside the mixer body increases, and the magnetic piston breaks free from the permanent magnet ring and moves upward. When the magnetic piston moves above the exhaust pipe, the water vapor enters the steam curing chamber through the exhaust pipe. This realizes the rational utilization of the heat and water vapor generated during the mixing process, which can effectively avoid energy waste and make the device more environmentally friendly.

[0033] S5, steaming, the block mold and the material are put into the steaming bin, and high-temperature steam is used for steaming;

[0034] The mixer used in the manufacturing method of the aerated concrete block comprises a mixer body 1, a fixed pipe 13 fixedly connected to the inner top of the mixer body 1, a stirring mechanism arranged in the mixer body 1 and used for stirring materials, the stirring mechanism comprising a driving rod 26 rotatably connected to the inner bottom of the mixer body 1, three fourth fixed blocks 25 fixedly connected to the two end side walls of the driving rod 26, a plurality of stirring blades 9 rotatably connected to the fourth fixed blocks 25, a third fixed block 22 fixedly connected to the opposite side wall of each of the plurality of stirring blades 9, a linkage rod 23 rotatably connected between every two third fixed blocks 22, a sleeve ring 15 slidably sleeved on the fixed pipe 13, an adjusting mechanism arranged on the sleeve ring 15 and used for adjusting the inclination angle of the stirring blades 9, the adjusting mechanism comprising a first fixed block 14 fixedly connected to the two end side walls of the sleeve ring 15, a rotating rod 8 rotatably connected to each of the two first fixed blocks 14, a second fixed block 21 rotatably connected to the end of each of the two rotating rods 8 away from the first fixed block 14, and the two second fixed blocks 21 being fixedly connected to the two stirring blades 9 above, respectively, a feeding port 2 formed in the upper end of the mixer body 1, a sealing cover plate 3 arranged at the feeding port 2, a discharge port 10 arranged on the side wall of the mixer body 1, a valve arranged on the discharge port 10, a water pump 5 arranged on the side wall of the mixer body 1, it is worth mentioning that the water pump 5 can supplement the water in the mixer body 1, when the water is evaporated in the form of water vapor, the water pump 5 can be used for pumping water, and a feeding machine 4 is installed on the side wall of the mixer body 1 and communicates with the mixer body 1 through a feeding pipe 24.

[0035] A base 11 is fixedly connected to the lower end of the mixer body 1, and a driving mechanism for driving the stirring mechanism is arranged in the base 11, the driving mechanism comprising a motor 12 fixedly connected to the inner bottom of the base 11, and the output shaft of the motor 12 is fixedly connected to the lower end of the driving rod 26.

[0036] A collecting mechanism for collecting steam generated in the mixing process is arranged in the fixed pipe 13, the collecting mechanism comprising a permanent magnet ring 17 fixedly connected to the inner wall of the fixed pipe 13, and a magnetic piston 16 slidably connected in the fixed pipe 13, the magnetic piston 16 cooperating with the permanent magnet ring 17, an exhaust pipe 6 is arranged in communication with the side wall of the fixed pipe 13, the exhaust pipe 6 penetrates through the side wall of the mixer body 1 and is connected with a steam curing chamber 7, the steam curing chamber 7 is provided with a temperature control device, the lower end of the magnetic piston 16 is rotatably connected with a supporting rod 20, the two end side walls of the supporting rod 20 are fixedly connected with horizontal rods 19, the end portions of the two horizontal rods 19 are fixedly connected with vertical rods 18, and the upper ends of the two vertical rods 18 are fixedly connected with the lower end of the sleeve ring 15.

[0037] In use, slag, straw ash, cement, and water are mixed in a certain proportion and poured into the mixer body 1. Lime powder is then added to the feeding machine 4. Subsequently, the output shaft of the drive motor 12 rotates, causing the drive rod 26 to rotate. The rotation of the drive rod 26 causes the fourth fixed block 25 and the mixing blades 9 on it to rotate. During the mixing process, lime powder is intermittently and quantitatively added to the mixer body 1 through the feeding machine 4. When lime powder is added, it reacts with water at high temperature within the mixer body 1, causing the water temperature to rise and generating steam. As the steam accumulates within the mixer body 1, the pressure inside the mixer body 1 increases. The steam pushes the magnetic piston 16 upwards. During the upward movement of the magnetic piston 16, it drives the support rod 20, the crossbar 19, and... The vertical rod 18 moves upward, causing the collar 15 to move upward, which in turn causes the rotating rod 8 to rotate. Under the pull of the rotating rod 8 and the linkage rod 23, the angles of multiple stirring blades 9 change. When the magnetic piston 16 moves upward above the exhaust pipe 6, steam is discharged from the exhaust pipe 6. After the steam in the main body 1 of the mixer is gradually discharged, the magnetic piston 16 moves downward and resets under the attraction of the permanent magnet ring 17, causing the collar 15 to reset. When the collar 15 resets, it pushes the rotating rod 8 to reset, causing the tilt angle of the stirring blades 9 to change again. This stirring method has a clever structure and can expand the stirring range of the stirring blades 9, thereby enabling more thorough stirring of the materials. It is worth mentioning that after each feeding by the feeder 4, the lime powder and water will react, which will cause the stirring blades 9 to continuously change their angle.

[0038] When the feeder 4 feeds lime powder into the mixer body 1, the lime powder reacts with the water inside the mixer body 1, causing water vapor to be generated inside the mixer body 1. After the water vapor accumulates to a certain extent, the pressure inside the mixer body 1 increases, and the magnetic piston 16 breaks free from the restraint of the permanent magnet ring 17 and moves upward. When the magnetic piston 16 moves above the exhaust pipe 6, the water vapor enters the steam curing chamber 7 through the exhaust pipe 6, realizing the rational utilization of the heat and water vapor generated during the mixing process, effectively avoiding energy waste and making the device more environmentally friendly.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
