In the process of preparing ceramsite concrete, the foaming device plays a key role, which is used to generate uniform and stable foam to fully mix with raw materials such as ceramsite to form high-performance ceramsite concrete.
[0003] A series of shortcomings have emerged in the traditional foaming device during the preparation of ceramsite concrete. In terms of foam quality, the foam produced by some existing devices has different sizes, resulting in obvious non-uniformity in the internal structure of ceramsite concrete, which in turn has a negative impact on its mechanical properties and overall quality. From the perspective of foaming efficiency, due to unreasonable structural design, the foaming speed of some devices is slow, making it difficult to fit the rhythm of large-scale production, resulting in low production efficiency.

One end of the flow controller 16 close to the mixing tank 3 is detachably connected to a microporous generator 15. The outside of the microporous generator 15 is fixedly connected to the inner wall of the convex cover 13. The microporous generator 15 is made of special ceramic material, and a large number of tiny pores are distributed on its surface. The size and distribution of the pores are accurately designed to evenly disperse the gas into the mixing tank 3. The outside of the microporous generator 15 is fixedly connected to the inner wall of the convex cover 13 by welding to ensure its stability during operation.
[0018] In the middle of the material discharging chamber 2, a rotating roller 18 is rotatably connected. The rotating roller 18 is made of alloy steel, having high strength and wear resistance. A plurality of swing rods 19 are fixedly connected to the outside of the rotating roller 18. The swing rods 19 are evenly distributed and are made of the same material as the rotating roller 18. Driven by the rotating roller 18, the swing rods 19 can mechanically disturb the falling foam material, effectively break the larger particle aggregates in the foam, and disperse the adhesion of viscous materials. On the front and rear sides of the outside of the rotating roller 18, connecting rods 20 are fixedly connected. The connecting rods 20 are made of high-strength metal rods. One end of the connecting rod 20 away from the rotating roller 18 is rotatably connected to a pull rod 21, and the pull rod 21 can move up and down driven by the connecting rod 20.
[0019] At the bottom end of the pull rod 21, a sieve mesh 22 is fixedly connected. The sieve mesh 22 is made of stainless steel, and the size of its mesh holes is strictly screened, which can perform the final homogenization treatment on the falling foam raw material, effectively eliminating possible large air bubbles and uneven phenomena. On the front side of the outside of the rotating roller 18, a connecting plate 23 is fixedly connected. The connecting plate 23 plays a role in connection and transmission. At the bottom end of the material discharging chamber 2, two through pipes 24 are fixedly connected. The through pipes 24 are made of corrosion-resistant plastic, and their pipe diameters can meet the smooth transportation of the foam material. An annular groove 25 is opened inside the through pipe 24. At the bottom end of the through pipe 24, a conveying assembly is fixedly connected. The conveying assembly is responsible for conveying the homogenized foam to the ceramsite concrete mixer.
[0020] The outside of the swing rod 19 is slidably connected to the inner wall of the annular groove 25. The outside of the swing rod 19 is slidably connected to the inner wall of the annular groove 25 through a sliding bearing, ensuring that the swing rod 19 can swing left and right flexibly. At the bottom end of the through pipe 24, a conveying assembly is fixedly connected. The conveying assembly includes a discharge pipe 26. The discharge pipe 26 is made of stainless steel, and its pipe diameter and length are designed according to actual production requirements, which can ensure the stable transportation of the foam material. The left and right sides of the top end of the discharge pipe 26 are fixedly connected to the bottom end of the through pipe 24 by welding, ensuring the firmness and tightness of the connection.
[0021] Reference Figure 1, the top end of the second support 31 is fixedly connected by welding with a raw material tank 32. The raw material tank 32 is made of stainless steel and has a relatively large volume, capable of storing sufficient raw material additives. On one side of the raw material tank 32 close to the first support 1, three bellows 33 are fixedly connected by welding. The bellows 33 are made of corrosion-resistant rubber material and have good flexibility, capable of adapting to the minor displacement of the raw material tank 32 during operation. On one side of the raw material tank 32 close to the mixing tank 3, a metering pump 34 is provided. The metering pump 34 is a high-precision metering pump, capable of precisely delivering the raw material additives into the mixing tank 3 according to the preset flow rate. On one side of the raw material tank 32 close to the mixing tank 3, a liquid level sensor 35 is also provided. The liquid level sensor 35 is an ultrasonic liquid level sensor 35, capable of real-time monitoring of the liquid level height of the raw material additives in the raw material tank 32. When the liquid level is lower than the set value, an alarm is sent in a timely manner to remind the staff to add raw materials.
[0022] At the rear side of the discharge pipe 26, a second motor 27 is fixedly connected. The driving end of the second motor 27 is fixedly connected with an auger 28. The second motor 27 is a motor with high torque output and can drive the auger 28 to rotate stably. The driving end of the second motor 27 is fixedly connected with the auger 28 through a coupling. The outside of the auger 28 is movably connected to the inner wall of the discharge pipe 26. The auger 28 is designed with spiral blades and can effectively push out the foam material. At the front end outside of the auger 28, a transmission rod 29 is fixedly connected. One end of the transmission rod 29 away from the auger 28 is rotatably connected with a connecting roller 30. The arrival rotation of the connecting roller 30 is rotatably connected to one end of the connecting plate 23 away from the rotating roller 18. The connecting roller 30 can rotate driven by the transmission rod 29. The bottom end of the connecting roller 30 is rotatably connected to one end of the connecting plate 23 away from the rotating roller 18 through a pin shaft, so as to realize the power of the second motor 27 being transmitted to the connecting roller 30 through the auger 28 and the transmission rod 29, and then drive the rotating roller 18 to swing left and right reciprocally.
[0023] Working principle: When the foaming device of the present invention is started, first, water raw materials are infused into the mixing tank 3 through the feed pipe 12, and then the raw material additives in the raw material tank 32 are transported to the mixing tank 3 through the quantitative delivery pump 34 according to the preset flow rate, and then the feed pipe 12 and the opening of the raw material tank 32 are closed. At the same time, the gas tank 14 compresses the air gas according to the set pressure through the pressure regulating valve and the air pump connected by the pipeline, and cooperates with the flow controller 16 to adjust the gas flow. The gas is injected into the microporous generator 15, and the microporous generator 15 evenly delivers the gas to the mixing tank 3 through a large number of tiny pores on the surface, so that the liquid raw material and the gas are fully mixed to form a preliminary foam that can be further refined and homogenized. Then the first motor 5 is started to drive the main rotating wheel 6, and the belt 7 outside the main rotating wheel 6 pulls the rotating shaft 8 and the stirring frame 9 fixed from the rotating wheel 11 to stir the liquid raw material in the mixing tank 3 at a high speed. While stirring, the frequency converter 10 is cooperated to adjust the stirring speed.
[0024] Under the action of the high-speed agitator, the liquid raw material and the gas are fully mixed to form preliminary foam, and then the second motor 27 is started to drive the auger 28 to rotate. After the auger 28 rotates, the transmission rod 29 fixed on the front side of the auger 28 drives the connecting roller 30 to rotate on the surface of the transmission rod 29 with the axis of the auger 28 as the center, and rotates periodically. At this time, when the connecting roller 30 rotates, the connecting plate 23 fixed on the top of the connecting roller 30 also drives the rotating roller 18 to swing back and forth in the middle of the material chamber 2, so that the swing rod 19 in the middle of the rotating roller 18 swings left and right to produce mechanical disturbance to the falling foam material, so as to break up the larger particle agglomerates in the foam in time and break up the adhesion of the sticky material. The crushed foam material will flow to the position of the through pipe 24. At this time, the connecting rods 20 fixed on both sides of the roller 18 pull the screen 22 to slide up and down in the annular groove 25 through the pull rod 21, and the falling foam raw materials are finally homogenized to eliminate possible large bubbles and uneven phenomena. Finally, the homogenized foam flows into the discharge pipe 26 through the through pipe 24 and is transported to the expanded clay concrete mixer by the rotating auger 28 to be mixed with other raw materials, completing the preparation process of expanded clay concrete.
