Description

Technical Field

[0001] The utility model belongs to the technical field of mixing equipment, and particularly relates to a high-strength pre-mixing processing device for polycarboxylate superplasticizer. Background Technique

[0002] Polycarboxylate superplasticizer is a high-performance concrete admixture, which has many characteristics such as high water reduction rate, improving concrete strength, low slump loss, environmental protection, versatility and economy. It is widely used in the concrete construction of water conservancy, electric power, port, railway, bridge, highway, airport, military projects and various civil building main structures, and is especially suitable for the concrete construction with a long construction time and high requirements for maintaining the slump of concrete.

[0003] During the production and processing of polycarboxylate superplasticizer, in order to ensure that each raw material component of polycarboxylate superplasticizer can be evenly distributed, achieve homogeneity at the macroscopic or microscopic level, improve the reaction efficiency and control the product quality, it is often necessary to stir and mix the raw material components of polycarboxylate superplasticizer. However, the traditional stirring structure usually adopts a structure mode of rotating and stirring with a fixed axis. At a limited rotation speed, it is difficult to obtain a high-strength stirring and mixing effect. And during the production and processing of polycarboxylate superplasticizer, too high a stirring speed may cause local overheating or too fast reaction, affecting the product quality. Therefore, the existing traditional stirring mechanism that rotates and stirs with a fixed axis is not conducive to the production and processing of polycarboxylate superplasticizer. For this reason, this application proposes a high-strength pre-mixing processing device for polycarboxylate superplasticizer. Summary of the Utility Model

Detailed implementation mode

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] This implementation mode provides a high-strength pre-stirring processing device for polycarboxylate superplasticizer, and its structural schematic diagram is as Figures 1-4 shown, including a stirring and mixing tank 1, a mounting plate 2 horizontally arranged at the top of the stirring and mixing tank 1; a mounting frame 3 rotatably installed in the middle of the mounting plate 2; a stirring mechanism 4 rotatably installed on the mounting frame 3 for stirring and mixing the raw materials of polycarboxylate superplasticizer in the stirring and mixing tank 1; the rotation axes of the stirring mechanism 4 and the mounting frame 3 are horizontally perpendicular to each other, and a driving mechanism 7 for driving the mounting frame 3 and the stirring mechanism 4 to swing is arranged on the mounting plate 2. By this structural method, the stirring mechanism 4 can be driven to swing along an arc track in the stirring and mixing tank 1 and rotate itself to stir and mix the raw materials of polycarboxylate superplasticizer. Compared with the traditional stirring structure that rotates and stirs with a fixed axis, this stirring structure expands the stirring range. Without increasing the stirring speed, the stirring and mixing intensity of the raw materials of polycarboxylate superplasticizer can be improved. While avoiding local overheating or too fast reaction caused by too high stirring speed and affecting the product quality, it ensures that each raw material component of polycarboxylate superplasticizer can be evenly distributed, improves the reaction efficiency, and thus controls the product quality.

[0025] In this embodiment, a U-shaped mounting frame 6 arched upward is provided in the middle of the rack plate 2. The mounting frame body 3 is rotatably mounted on the inner bottom of the U-shaped mounting frame 6. The stirring mechanism 4 includes a second motor 11 rotatably mounted in the mounting frame body 3, a shaft rod 12 connected to the driving shaft of the second motor 11, and a stirring paddle 13 mounted at the bottom end of the shaft rod 12. The rotating connection shaft of the second motor 11 and the mounting frame body 3 is perpendicularly distributed to the rotating connection shaft of the mounting frame body 3 and the U-shaped mounting frame 6. The driving mechanism 7 includes a transmission arm 10 rotatably mounted on the inner top wall of the U-shaped mounting frame 6 and a first motor 9 mounted on the top of the U-shaped mounting frame 6 for driving the transmission arm 10 to rotate. One end of the transmission arm 10 away from the first motor 9 is rotatably connected to the top end of the second motor 11. The end of the transmission arm 10 connected to the driving shaft of the first motor 9 is horizontally arranged. The end of the transmission arm 10 connected to the second motor 11 is bent downward and is perpendicular to the shaft rod 12. And the rotating connection shaft of the transmission arm 10 and the second motor 11 is coaxially distributed with the shaft rod 12. Through this special structural method, during the process of the first motor 9 driving the transmission arm 10 to rotate horizontally, the stirring paddle 13 is driven to move along an arc trajectory in the stirring and mixing tank 1 in an inclined state. The second motor 11 is synchronously started to drive the shaft rod 12 to drive the stirring paddle 13 to rotate. The stirring paddle 13 can then move along an arc trajectory in the stirring and mixing tank 1 and rotate itself to stir and mix the raw materials of the polycarboxylate superplasticizer. Without the need to increase the rotation speed, the stirring and mixing intensity of the raw materials of the polycarboxylate superplasticizer is improved.

[0026] In a further embodiment, a mounting block 8 is provided at the top of the outer side wall of the stirring and mixing tank 1. The end of the rack plate 2 is bolted to the mounting block 8, which is beneficial to the disassembly and assembly of the rack plate 2. A baffle plate 5 is vertically arranged on the inner wall of the stirring and mixing tank 1. The thickness of the baffle plate 5 gradually decreases in the rotation direction of the stirring mechanism 4 and is smoothly attached to the inner wall of the stirring and mixing tank 1. A circular arc surface is provided on the thicker side of the baffle plate 5. Through this special structural method, during the process of the stirring paddle 13 stirring and mixing the raw materials of the polycarboxylate superplasticizer, the baffle plate 5 can block the raw materials. An overflow groove 14 is horizontally opened on the baffle plate 5, which can enable the blocked part of the raw materials to flow through. Without the need to increase the rotation speed, the stirring and mixing intensity of the raw materials of the polycarboxylate superplasticizer is further improved. In addition, the inner side wall of the overflow groove 14 gradually approaches the middle of the stirring and mixing tank 1 in the rotation direction of the stirring mechanism 4. Thus, the part of the raw materials overflowing from the overflow groove 14 can flow towards the middle of the stirring and mixing tank 1, generating a turbulence effect to improve the mixing intensity.

[0027] Working principle: During use, the raw materials of the polycarboxylate superplasticizer are put into the stirring and mixing tank 1, and then the first motor 9 is started to drive the transmission arm 10 to rotate. Since the second motor 11 is rotatably installed in the installation frame 3, the installation frame 3 is rotatably installed in the U-shaped installation frame 6, and the installation frame 3 is vertically distributed with the rotating shaft of the second motor 11. In addition, one end of the transmission arm 10 connected to the second motor 11 bends downward and is perpendicular to the shaft rod 12. The rotating connection shafts of the transmission arm 10 and the second motor 11 are coaxially distributed with the shaft rod 12. Furthermore, during the horizontal rotation of the transmission arm 10 driven by the first motor 9, the stirring paddle 13 will be driven to move along an arc trajectory in the stirring and mixing tank 1 in an inclined state. At this time, the second motor 11 is synchronously started to drive the shaft rod 12 to drive the stirring paddle 13 to rotate. The stirring paddle 13 can then move along an arc trajectory in the stirring and mixing tank 1 and rotate itself to stir and mix the raw materials of the polycarboxylate superplasticizer. Compared with the traditional stirring structure that rotates and stirs and mixes around a fixed axis, this stirring structure expands the stirring range. Without increasing the stirring speed, the stirring and mixing intensity of the raw materials of the polycarboxylate superplasticizer can be increased. While avoiding local overheating or too fast reaction caused by too high stirring speed and affecting the product quality, it ensures that each raw material component of the polycarboxylate superplasticizer can be evenly distributed, improves the reaction efficiency, and thus controls the product quality. Further, through the baffle 5 vertically arranged on the inner wall of the stirring and mixing tank 1, it can block the flow during the stirring and mixing process of the raw materials of the polycarboxylate superplasticizer by the stirring paddle 13. The overflow groove 14 on the baffle 5 can enable the blocked part of the raw materials to flow, and further improves the stirring and mixing intensity of the raw materials of the polycarboxylate superplasticizer without the need to increase the rotation speed.
