Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically to a device for green construction of thickened cement premixed mortar. Background Technology

[0002] Green construction refers to construction activities that, while ensuring basic requirements such as quality and safety, maximize resource conservation and minimize negative environmental impacts through scientific management and technological advancements, thereby achieving the goals of saving resources, reducing environmental impact, and protecting the environment.

[0003] Thickened cement premixed mortar is made by mixing cement, sea sand, aluminum slag, methylcellulose, basalt fiber, thickener and polycarboxylate superplasticizer. The thickened cement premixed mortar prepared by this method not only reduces costs, but also realizes the reuse of industrial waste such as aluminum slag, which is conducive to environmental protection and resource recycling.

[0004] However, existing green construction mixing equipment still has some shortcomings when mixing thickened cement premixed mortar:

[0005] 1. In the existing technology, when mixing thickened cement premixed mortar, most green construction mixing equipment mixes the slurry in the center, making it difficult to mix the slurry in the surrounding area evenly. This results in incomplete mixing and poor mixing effect, which in turn affects the quality of the prepared thickened cement premixed mortar.

[0006] 2. At the same time, the mixing components of the mixing equipment cannot be separated from the mixing tank, which makes it difficult to clean the slurry adhering to the mixing tank and the mixing paddle. This makes cleaning the mixing tank and the mixing paddle inconvenient and requires a high level of cleaning effort. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-7 As shown, this utility model provides a device for green construction of thickened cement premixed mortar, including a mixing tank 1. A slurry discharge pipe 11 is fixedly installed on the bottom end face of the mixing tank 1. After the thickened cement premixed mortar is prepared by mixing, it can be discharged through the slurry discharge pipe 11. An equipment ring 2 is detachably installed on the upper end face of the mixing tank 1. Four threaded holes 12 are arranged in a ring array on the outer wall of the mixing tank 1. Four mounting bolts 21 are arranged in a ring array and rotatably installed on the outer wall of the equipment ring 2. One of the mounting bolts 21 is threadedly connected to the inner wall of one of the threaded holes 12. By rotating the mounting bolt 21, the mounting bolt 21 is separated from the threaded hole 12, and the equipment ring can be removed. 2. Remove from mixing tank 1 to facilitate inspection and maintenance of mixing mechanism 3 on equipment ring 2. U-shaped equipment frame 22 is fixedly installed on the outer wall of equipment ring 2. Mixing mechanism 3 is provided on equipment ring 2. Lifting mechanism 5 is provided on U-shaped equipment frame 22. By setting mixing mechanism 3 and lifting mechanism 5, mixing mechanism 3 can mix thickened cement premixed mortar in mixing tank 1 in all directions. Lifting mechanism 5 can adjust the mixing position of mixing mechanism 3, so that thickened cement powder and sand can be mixed in all directions to improve the mixing effect. At the same time, lifting mechanism 5 can raise mixing mechanism 3, so that operators can clean the inner wall of mixing tank 1.

[0026] The stirring mechanism 3 includes a U-shaped fixed frame 31, with stirring rods 32 rotatably mounted at both ends of the U-shaped fixed frame 31. Stirring paddles 33 are fixedly mounted on each of the two stirring rods 32. A rotating shaft 34 is rotatably mounted on the U-shaped fixed frame 31. A circular guide rail 35 is fixedly mounted on the inner wall of the equipment ring 2. Two arc-shaped blocks 36 are slidably mounted on the circular guide rail 35. Each of the two arc-shaped blocks 36 has a connecting groove 37. One end of the rotating shaft 34 is in movable contact with the inner wall of one of the connecting grooves 37. By providing the connecting groove 37, the arc-shaped block 36 can cause the rotating shaft 34 to rotate circumferentially through the connecting groove 37. Simultaneously, After stirring, when the rotating shaft 34 rises vertically, it can disengage from the arc-shaped block 36 through the connecting groove 37. The arc-shaped block 36 then slides circumferentially on the circular guide rail 35. The arc-shaped block 36, through the connecting groove 37, causes the rotating shaft 34 to rotate circumferentially. The rotating shaft 34, through the U-shaped fixing frame 31, causes the two stirring rods 32 and two stirring paddles 33 to rotate circumferentially within the mixing tank 1. A transmission gear 38 is fixedly installed at one end of the rotating shaft 34. A fixed gear disc 39 is fixedly installed on the inner wall of the equipment ring 2. The transmission gear 38 and the fixed gear disc 39 mesh with each other. When the rotating shaft 34 rotates circumferentially, the transmission gear 38 engages with the fixed gear disc. The fixed gear 39 rotates in a circular motion, forcing the transmission gear 38 to rotate. The transmission gear 38 causes the rotating shaft 34 to rotate. One end of each of the two stirring rods 32 is fixedly equipped with a first bevel gear 321, and the other end of the rotating shaft 34 is fixedly equipped with two second bevel gears 341. One of the second bevel gears 341 meshes with one of the first bevel gears 321. When the rotating shaft 34 rotates, it can cause the first bevel gear 321 to rotate via the second bevel gears 341, which in turn causes the stirring rods 32 to rotate. A first motor 4 is fixedly mounted on the outer wall of the equipment ring 2, and the fixed end of the first motor 4 is fixed... A first fixed block 41 is installed, one end of which is fixedly connected to the outer wall of the equipment ring 2. A rotating rod 42 is fixedly installed at the drive output end of the first motor 4. A drive gear 43 is fixedly installed at one end of the rotating rod 42. A movable gear 44 is fixedly installed on the upper surface of the two arc-shaped blocks 36. The drive gear 43 and the movable gear 44 are meshed together. When the first motor 4 is turned on, the drive shaft of the first motor 4 can make the rotating rod 42 rotate. The rotating rod 42 makes the drive gear 43 rotate. The drive gear 43 makes the movable gear 44 rotate. The movable gear 44 makes the arc-shaped blocks 36 slide circumferentially on the circular guide rail 35.

[0027] The lifting mechanism 5 includes a frame plate 51. A connecting shaft 52 is fixedly installed at one end of the frame plate 51. One end of the connecting shaft 52 is rotatably connected to one end of the U-shaped fixed frame 31. The connecting shaft 52 is coaxial with the mixing tank 1. When the U-shaped fixed frame 31 revolves, it revolves around the axis of the connecting shaft 52. The connecting shaft 52 and the U-shaped fixed frame 31 are damped, so the U-shaped fixed frame 31 will not revolve on its own without external force. A slide groove 53 is provided on the U-shaped equipment frame 22. A slider 54 is slidably installed at one end of the slide groove 53. The other end of the frame plate 51 is fixedly connected to one side of the slider 54. By driving the slider 54 in the slide groove 53... The slider 54 slides vertically within the slide groove 53. The U-shaped fixed frame 31, stirring rod 32, and stirring paddle 33 can be vertically raised through the frame plate 51 and connecting shaft 52. A second motor 55 is fixedly installed at one end of the U-shaped equipment frame 22. A second fixed block 56 is fixedly installed at the fixed end of the second motor 55. One end of the second fixed block 56 is fixedly connected to one end of the U-shaped equipment frame 22. A lead screw 57 is fixedly installed at the drive output end of the second motor 55. The lead screw 57 passes through the slide groove 53 and is threadedly connected to the slider 54. By turning on the second motor 55, the drive shaft of the second motor 55 can make the lead screw 57 rotate. The lead screw 57 can drive the slider 54 to slide vertically within the slide groove 53.

[0028] Working principle: When thickened cement mortar needs to be prepared, the operator first pours the thickened cement powder and sand into the mixing tank 1, and then turns on the first motor 4. The drive shaft of the first motor 4 rotates the drive gear 43 through the rotating rod 42. The drive gear 43 rotates the movable gear disk 44. The movable gear disk 44 causes the two arc-shaped blocks 36 to slide circumferentially on the circular guide rail 35. The two arc-shaped blocks 36, through the connecting groove 37, cause the rotating shaft 34, the transmission gear 38, the U-shaped fixing frame 31, the two stirring rods 32, and the two stirring paddles 33 to rotate circumferentially within the mixing tank 1. Simultaneously, the fixed gear disc 39 forces the transmission gear 38 to rotate, which in turn causes the rotating shaft 34 to rotate. The rotating shaft 34, through two second bevel gears 341 and two first bevel gears 321, causes the two stirring rods 32 to rotate and the two stirring paddles 33 to rotate. At this time, the two stirring paddles 33 revolve around the mixing tank 1 and rotate on their own axis, thus performing all-round mixing of the thickened cement powder and sand in the mixing tank 1. This facilitates the full mixing of the thickened cement powder and sand, thereby effectively improving the quality of the prepared thickened cement premixed mortar.

[0029] After the mixing operation is completed, the thickened cement premixed mortar in the mixing tank 1 is discharged through the slurry discharge pipe 11. At this time, the operator turns on the second motor 55. The drive shaft of the second motor 55 causes the lead screw 57 to rotate. The lead screw 57 drives the slider 54 to slide vertically upward in the slide groove 53. The slider 54 causes the U-shaped fixing frame 31, the two mixing rods 32 and the two mixing paddles 33 to rise vertically through the frame plate 51 and the connecting shaft 52 until the two mixing paddles 33 are completely separated from the mixing tank 1. Then the second motor 55 is turned off. At this time, the operator can use an external spray gun to wash the inner wall of the mixing tank 1 and the mixing paddles 33 to wash away the attached slurry. The washed-away slurry and the washing water are discharged through the slurry discharge pipe 11, thus conveniently cleaning the inner wall of the mixing tank 1 and the mixing paddles 33. This effectively improves the convenience of cleaning the attached slurry and reduces the cleaning intensity of the operator.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
