Description

Technical Field

[0001] This utility model belongs to the field of building materials technology, and in particular relates to a conveying device for the preparation of polycarboxylate superplasticizer. Background Technology

[0002] In the construction process, commonly used building materials include concrete, steel bars, and bricks. Concrete refers to an engineering composite material in which aggregates are bound together by a cementing material. It typically uses cement as the cementing material, sand and gravel as aggregates, and is hardened after being mixed with water in a specific ratio. Adding polycarboxylate superplasticizers to concrete improves its workability, mechanical properties, and durability. During the preparation of polycarboxylate superplasticizers, a conveying device is needed to introduce the raw materials into the preparation equipment. However, conventional conveying devices still have the following shortcomings in practical use:

[0003] 1. When conveying raw materials for polycarboxylate superplasticizer preparation, multiple different raw materials need to be introduced into the preparation device one by one, which increases the conveying time and reduces the efficiency of polycarboxylate superplasticizer preparation.

[0004] 2. When conveying raw materials for polycarboxylate superplasticizer preparation, the simple structure of the conveying device makes it inconvenient to stir and mix different types of raw materials, reducing functionality. The subsequent stirring and mixing requires more time, which is not conducive to the uniform mixing of different types of raw materials for polycarboxylate superplasticizer preparation and reduces the quality of polycarboxylate superplasticizer preparation.

[0005] To address these issues, we provide a conveying device for the preparation of polycarboxylate superplasticizers. Utility Model Content

[0006] The purpose of this invention is to provide a conveying device for the preparation of polycarboxylate superplasticizers. By setting up a conveying component, different types of polycarboxylate superplasticizer preparation raw materials can be conveyed simultaneously, reducing the conveying time and accelerating the preparation efficiency of polycarboxylate superplasticizers. Furthermore, by setting up a stirring component, different types of polycarboxylate superplasticizer preparation raw materials can be stirred in advance, which is beneficial for thorough mixing of polycarboxylate superplasticizer preparation raw materials in the later stage, improving the preparation quality of polycarboxylate superplasticizers, thereby solving the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a conveying device for the preparation of polycarboxylate superplasticizer, comprising a conveying tank with a through hole, a conveying assembly on the upper outer side of the conveying tank, the conveying assembly including an aggregating box mounted on the upper outer side of the conveying tank, a nozzle connected to the lower surface of the aggregating box inserted into the through hole, a peristaltic pump mounted on the upper surface of the aggregating box, a flexible hose connected to the peristaltic pump having an end connected to the aggregating box, and a multi-port pipe connected to the other end of the flexible hose, with flow valves connected to equidistant branch pipes on the multi-port pipe; and a stirring assembly inside the conveying tank, the stirring assembly including a tank cover located on the opening side of the conveying tank, and a fan blades arranged in a ring array around a rotating shaft rotatably connected at the center of the tank cover.

[0009] The present invention is further configured such that the lower outer part of the conveying barrel has a communicating conveying hopper, and the upper outer part of the conveying barrel has a communicating pneumatic valve.

[0010] The present invention is further provided that the lower outer side of the conveying barrel has a symmetrically fixed mounting frame, and the mounting frame has an L-shaped structure.

[0011] The present invention is further configured such that the conveying barrel has an annular array of screws fixedly connected to the open side wall, the screws penetrate the barrel cover, and the nuts threaded around the screws abut against the outer side wall of the barrel cover.

[0012] The present invention is further configured such that the cross-section of the bucket lid is a T-shaped structure, and a sealing ring is provided on the periphery of the bucket lid.

[0013] The present invention is further configured such that a rotatably connected support plate is provided on the circumference of the rotating shaft, the support plate is located away from the barrel lid, a positioning hole is provided on the side wall of the support plate, and a positioning rod is fixedly connected to the inner side wall of the conveying barrel, the positioning rod being inserted into the positioning hole.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up a conveying component, connects multiple branch pipes to the discharge ports of multiple polycarboxylate superplasticizer preparation raw material boxes. When the peristaltic pump is powered on, the raw materials inside the multiple polycarboxylate superplasticizer preparation raw material boxes simultaneously enter the multi-port pipe through the branch pipes, and then enter the collection box. It eliminates the need to introduce different types of polycarboxylate superplasticizer preparation raw materials into the collection box one by one, reduces the material guiding time, and allows for faster mixing of different types of polycarboxylate superplasticizer preparation raw materials, which helps to accelerate the efficiency of polycarboxylate superplasticizer preparation.

[0017] 2.
