Description

Technical Field

[0001] This utility model relates to the field of polycarboxylate superplasticizer preparation technology, specifically to modular polycarboxylate superplasticizer manufacturing equipment. Background Technology

[0002] Polycarboxylate superplasticizer is a high-performance water-reducing agent, belonging to the category of cement dispersants in cement concrete, and is widely used in the construction engineering field. Performance characteristics: High water reduction rate: Water reduction rate can reach 45%, significantly reducing concrete water consumption and improving strength and durability. Low dosage: High plasticizing effect can be achieved at low dosages, resulting in significant economic benefits. Good slump retention: Effectively prevents concrete slump loss, extending construction time, especially suitable for long-distance transportation and large-volume concrete construction. Low concrete shrinkage rate: Reduces concrete shrinkage, improving volume stability and crack resistance. Highly adjustable molecular structure: By adjusting the main chain and side chain structure, different performance requirements can be achieved, such as retarding and early strength. Green and environmentally friendly: No formaldehyde is used in the production process, meeting the environmental protection requirements of modern building materials. Good compatibility with cement: Adaptable to various cement types, improving the uniformity and stability of concrete. Significant strengthening effect: Significantly improves the early and later strength of concrete. Good durability: Low chloride ion and alkali content, which is beneficial to the long-term durability of concrete.

[0003] In the preparation process of polycarboxylate superplasticizer, the raw materials need to be stirred and mixed by a stirring device. When the existing stirring device is used to stir the raw materials, due to the high viscosity of polycarboxylate superplasticizer, if the stirring paddle size is set too large, the stirring paddle will have a large resistance when rotating. If the stirring paddle size is set too small, the stirring efficiency and mixing uniformity of polycarboxylate superplasticizer will be affected, and it will be impossible to meet the requirements of rapid and uniform stirring of polycarboxylate superplasticizer. To solve the above problems, this application proposes a modular polycarboxylate superplasticizer manufacturing device. Utility Model Content

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

A telescopic sleeve 9 is slidably provided on the surface of the transmission rod 8. A stirring paddle 10 is circumferentially provided on the surface of the telescopic sleeve 9.

[0026] A screw-type electric telescopic rod 16 is installed on the top surface of the mixing tank 1.

A rotating connecting seat 11 is rotatably connected to the top surface of the telescopic sleeve 9. The piston rod end of the screw-type electric telescopic rod 16 is rotatably connected to the rotating connecting seat 11.

[0027] It should be noted that the electromagnetic heating furnace body 6 is installed on the bottom surface of the mixing tank 1.

During the heating process, the stirring motor 7 can drive the stirring paddle 10 to rotate through the transmission rod 8. The stirring paddle 10 can stir and mix the polycarboxylate superplasticizer raw material. The top of the telescopic sleeve 9 is connected to the piston rod end of the screw-type electric telescopic rod 16 through the rotating connecting seat 11, which can limit the top of the telescopic sleeve 9 and improve the stability of the stirring paddle 10 when stirring the polycarboxylate superplasticizer raw material. At the same time, by controlling the extension and retraction of the screw-type electric telescopic rod 16, the telescopic sleeve 9 can be moved on the transmission rod 8, thereby adjusting the stirring height of the stirring paddle 10 and improving the stirring efficiency and mixing uniformity of the polycarboxylate superplasticizer raw material.

[0028] In this embodiment, as Figure 1 As shown, a feed pipe 2 is conductively connected to the upper surface of the mixing tank 1, and a feed valve 3 is installed on the feed pipe 2. A discharge pipe 4 is conductively connected to the bottom of the side wall of the mixing tank 1, and a discharge valve 5 is installed on the discharge pipe 4.

[0029] It should be noted that the raw materials for preparing polycarboxylate superplasticizer are injected into the mixing tank 1 through the feed pipe 2. After the feed valve 3 is closed, the mixing tank 1 can be sealed, which can reduce the emission of harmful gases. After the preparation is completed, the discharge valve 5 is opened, and the prepared polycarboxylate superplasticizer can be discharged through the discharge pipe 4.

[0030] In this embodiment, as Figure 4 As shown, a water filter box 13 is installed on the side wall of the mixing tank 1.

The stirring paddle 10 can stir and mix the polycarboxylate superplasticizer raw materials. The top of the telescopic sleeve 9 is connected to the piston rod end of the screw-type electric telescopic rod 16 through the rotating connecting seat 11, which can limit the top of the telescopic sleeve 9 and improve the stability of the stirring paddle 10 when stirring the polycarboxylate superplasticizer raw materials. At the same time, by controlling the screw... The electric telescopic rod 16 extends and retracts, which drives the telescopic sleeve 9 to move on the transmission rod 8, thereby adjusting the stirring height of the stirring paddle 10. This improves the stirring efficiency and mixing uniformity of the polycarboxylate superplasticizer raw material. At the same time, the polycarboxylate superplasticizer raw material releases harmful gases after heating. After turning on the suction pump 14, the harmful gases in the mixing tank 1 can be extracted by the suction pump 14 and injected into the water filter box 13 through the air guide pipe 12.
