Description

Technical Field

[0001] The utility model relates to the technical field of aerated brick grouting, in particular to an aerated brick grouting mechanism. Background Art

[0002] Autoclaved aerated concrete blocks, referred to as aerated bricks, are aerated concrete blocks produced by high-temperature autoclaving equipment. They include bricks produced by various other processes including autoclaving. The production of aerated bricks requires steps such as slurry preparation, grouting, cutting, and curing. Grouting is the process of injecting the prepared slurry into the mold frame to form a green body. After the green body is formed, it is cut into the required shape and size. During the grouting process, when the slurry enters the mold frame from the grouting pipe, it will react with the mold frame and splash out of the mold frame, causing waste.

[0003] The prior art sets a splash-proof cover on the outer ring of the grouting pipe to prevent the slurry from splashing when it falls into the mold frame. However, when the slurry is discharged downward for grouting, most of the slurry will not directly contact the cover, and its falling speed remains unchanged. The impact of finally falling into the mold frame is still very large, which will cause serious slurry splashing. Therefore, we propose a grouting mechanism for aerated bricks. Utility Model Content

[0004] The utility model aims to provide an aerated brick grouting mechanism, in which inclined and staggered inclined plates are fixed inside the splash shield, and a plurality of buffer protrusions are evenly arranged on the surface of the inclined plates. When high-speed slurry enters the splash shield, it will first fall on the surface of the inclined plates and cooperate with the buffer protrusions to buffer and decelerate the slurry, so that the slurry can fall into the mold frame at a low speed, reducing the splashing of slurry caused by impact, avoiding waste, and solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grouting mechanism for aerated bricks, comprising a cross frame and a feed pipe, wherein the feed pipe vertically penetrates the middle position of the surface of the cross frame, and electric push rods are vertically installed on the surfaces of the cross frame on both sides of the feed pipe; a splash shield is fixed to the bottom of the electric push rod, a grouting pipe connected to the inside of the splash shield is connected above the splash shield, and the grouting pipe sleeve is placed on the lower outer ring of the feed pipe, and two inclined plates are fixed obliquely inside the splash shield, and the staggered connection of the two inclined plates is located below the grouting pipe, and buffer bumps are evenly arranged on the surface of the inclined plates; a card slot is opened around the upper inner ring of the grouting pipe, a rubber ring is embedded and fixed inside the card slot, and the inner ring of the rubber ring is integrally connected to a rubber ring sheet, and the inner ring of the rubber ring sheet is in contact with the outer surface of the feed pipe.

[0006] By adopting the above technical solution, the mold frame is placed under the cross frame and the splash shield is driven to descend to the upper part of the mold frame, so that the slurry enters the splash shield from the feed pipe and the grouting pipe. When falling, it will be buffered by the inclined plate and the buffer bump to reduce the speed, avoiding the generation of large impact force into the mold frame and splashing, thereby reducing waste.

[0007] Optionally, a flange is connected to the top of the feed pipe, and the inner circle of the flange is connected to the interior of the feed pipe.

[0008] By adopting the above technical solution, the pipeline of the grouting machine can be connected to the feed pipe through the flange.

[0009] Optionally, a slurry inlet is connected to the middle position of the surface of the splash shield, and the grouting pipe is connected to the interior of the splash shield through the slurry inlet.

[0010] Optionally, a support rod is transversely fixed on the inner side between the inclined plates, and both ends of the support rod are welded and fixed to the inner surface of the inclined plate through a welding plate.

[0011] By adopting the above technical solution, the inclined plate is supported by the internal support rods, which plays a role in stably fixing the inclined plate.

[0012] Optionally, four bottom corners of the horizontal frame are supported and fixed with pillars, and four pillars are provided.

[0013] By adopting the above technical solution, the lateral support of the cross frame is achieved through the pillars at the bottom of the cross frame.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The technical solution of the present application is to fix inclined and staggered inclined plates inside the splash shield, and multiple buffer bumps are evenly arranged on the surface of the inclined plates. When high-speed slurry enters the splash shield, it will first fall on the surface of the inclined plates and cooperate with the buffer bumps to buffer and slow down the slurry, so that the slurry can fall into the mold frame at a low speed, reducing the splash of slurry caused by impact and avoiding waste.

[0016] 2. The technical solution of the present application connects the grouting pipe to the outer ring of the feed pipe by means of a sleeve, and the inner ring of the grouting pipe is fixed with a rubber ring sheet that contacts the outer ring of the feed pipe, thereby ensuring that the grouting pipe can be driven to rise and fall to adjust the height of the splash guard while allowing the slurry to enter the grouting pipe normally from the feed pipe.

[0023] See also Figure 1-4 The utility model provides a technical solution: an aerated brick grouting mechanism, including a horizontal frame 1 and a feed pipe 2, the bottom four corners of the horizontal frame 1 are supported and fixed with pillars 11, four pillars 11 are provided, and the pillars 11 at the four corners have the same height, so that the horizontal frame 1 is supported and fixed horizontally.

[0024] The feed pipe 2 vertically penetrates the middle position of the surface of the cross frame 1, and the bottom of the feed pipe 2 penetrates to the bottom of the cross frame 1. The top of the feed pipe 2 is connected to a flange 21, and the inner circle of the flange 21 is connected to the inside of the feed pipe 2, so that the feed pipe 2 is connected to the slurry outlet pipe of the grouting machine through the flange 21 above it, so that the slurry can be introduced into the feed pipe 2 when needed.

[0025] Electric push rods 12 are vertically installed on the surface of the cross frame 1 on both sides of the feed pipe 2. The protruding ends of the electric push rods 12 pass through the bottom of the cross frame 1 and are placed on both sides of the feed pipe 2. A splash shield 3 is fixed to the bottom of the electric push rod 12. A slurry inlet 32 ​​is connected to the middle position of the surface of the splash shield 3. The slurry inlet 32 ​​is connected to the interior of the splash shield 3, so that a grouting pipe 31 connected to the interior of the splash shield 3 is connected to the top of the splash shield 3 through the slurry inlet 32, and the grouting pipe 31 is placed on the lower outer ring of the feed pipe 2. The slurry entering the feed pipe 2 is discharged from the bottom and then enters the grouting pipe 31, and then enters the splash shield 3.

[0026] A slot 311 is provided around the inner ring above the grouting pipe 31, and a rubber ring 5 is embedded and fixed inside the slot 311, and the inner ring of the rubber ring 5 is integrally connected to a rubber ring piece 51, and the rubber ring piece 51 surrounds the outer ring of the feed pipe 2, and its inner ring is in contact with the outer surface of the feed pipe 2. When the electric push rod 12 drives the splash cover 3 and the grouting pipe 31 to rise and fall, the grouting pipe 31 is always sleeved on the outer ring of the feed pipe 2 to rise and fall, and the rubber ring piece 51 slides up and down on the outer ring of the feed pipe 2 to seal the connection.

[0027] Two inclined plates 4 are fixed obliquely inside the splash shield 3, and the staggered connection of the two inclined plates 4 is located below the grouting pipe 31. Both ends of the inclined plates 4 are welded and fixed to the inner wall surface of the splash shield 3. Buffer bumps 42 are evenly arranged on the surface of the inclined plates 4. When the slurry enters the splash shield 3 at high speed, it falls on the surface of the inclined plates 4. Under the buffering and deceleration effect of the inclined plates 4 and the buffer bumps 42, the slurry discharge speed is reduced. The splash of the slurry when it hits the surface of the inclined plates 4 is blocked by the splash shield 3. Finally, the slurry falls into the mold frame to reduce splashing.

[0028] A support rod 41 is transversely fixed on the inner side between the inclined plates 4, and welding plates 411 are welded and fixed to the ends of both sides of the support rod 41, and the two ends of the support rod 41 are welded and fixed to the inner surface of the inclined plate 4 through the welding plates 411. There are multiple support rods 41 fixed in the longitudinal direction, which can support the inner side of the inclined plate 4 and ensure the supporting and fixing strength of the inclined plate 4.

[0029] When in use, the slurry outlet pipe of the grouting machine is connected to the feed pipe 2 through the flange 21, and the electric push rod 12 is connected to the control device. During grouting, the mold frame is placed below the cross frame 1, and the electric push rod 12 drives the splash guard 3 to be lowered to the upper part of the mold frame. Then the grouting machine pumps slurry into the feed pipe 2, and then enters the splash guard 3 through the grouting pipe 31 and the slurry inlet 32. The slurry falls downward onto the surface of the inclined plate 4, and cooperates with the multiple buffer bumps 42 arranged on its surface to buffer and slow down the descending speed of the slurry. The splashing effect caused by the slurry hitting the surface of the inclined plate 4 will be directly blocked by the splash guard 3, and finally the slurry falls downward into the mold frame at a low speed to reduce the splashing waste of the slurry.
