Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a concrete aggregate pretreatment device. Background Technology

[0002] In the concrete production process, the quality of aggregates directly affects the strength, durability, and workability of concrete. However, natural or artificially prepared aggregates are often contaminated with soil, dust, and other impurities during storage, transportation, and processing. If these contaminants are not effectively cleaned and screened, the quality of the concrete may decline, affecting the stability of the engineering structure. Furthermore, substandard aggregates may affect the workability of concrete, increasing construction difficulty and even leading to problems such as cracking and reduced strength. Therefore, pretreatment of aggregates is a crucial step in ensuring concrete quality. However, there are certain limitations in the pretreatment of concrete aggregates, especially in the synchronization of aggregate washing and screening. During the washing process, aggregates are usually statically soaked or sprayed, which makes it difficult to ensure the uniformity of washing. Some fine dust and dirt are difficult to remove completely, affecting the quality of aggregates. The screening process often relies on independent screening equipment. The screening and washing processes are independent of each other, resulting in a relatively dispersed overall process, increasing the processing time and the difficulty of process connection, affecting screening efficiency, and easily leading to material waste or incomplete cleaning, affecting the screening and washing effect. In addition, it requires additional manual intervention, increasing labor intensity, and needs to be improved. Utility Model Content

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model incorporates a sieve plate, scraper, side plate, water sprayer, filter conveyor belt, and motor. The motor drives the rotating roller to rotate, causing the filter conveyor belt to roll synchronously. During the conveying process, mud and dust are thoroughly washed away, improving the cleaning effect. Qualified aggregates after screening fall onto the sieve plate, while larger impurities that do not pass through the sieve continue to be discharged with the conveyor belt. This achieves screening and cleaning of aggregates during the conveying process, allowing them to be collected and discharged into storage or subsequent processing devices. This avoids material residue affecting screening efficiency, while also reducing manual intervention and improving the overall processing effect.

[0012] 2. This utility model incorporates a motor, a digging rod, a hopper, motor A, gears, and a hollow gear. Motor A drives the gears to rotate, which in turn drives the hollow gears to rotate synchronously, thereby adjusting the angle of the hopper. This allows for flexible adjustment of the feeding direction and discharge height to adapt to different conveying and processing requirements. It enables angle adjustment between the material input and output ends to meet the needs of different production processes. The motor drives the digging rod to rotate, ensuring uniform material flow within the hopper, preventing blockage at the discharge port, ensuring continuous and stable discharge, improving the smoothness of material conveying, reducing manual intervention, and increasing overall work efficiency.

A motor 19 drives the rotating roller 11, which in turn drives the filter conveyor belt 12 to operate, realizing the conveying, cleaning and screening of aggregates. The cooperation between the support roller 14 and the rotating roller A13... To improve the stability of the conveyor belt and ensure smooth material movement, one side of the scraper 3 is slidably connected to the interior of the casing 1, the surface of the water suction pipe 6 is fixedly connected to the interior of the casing 1, the surface of the conveying pipe 7 is fixedly connected to the interior of the cover plate 15, and the lower surface of the water sprayer 8 is fixedly connected to the upper surface of the machine plate 9.

Example

[0022] Please see Figure 1-4A vertical plate 17 is fixedly installed on the upper surface of the machine plate 9. An installation plate 18 is fixedly installed on the side of the vertical plate 17. A motor 19 is fixedly installed on the surface of the installation plate 18. A digging rod 20 is fixedly installed at the output end of the motor 19. One end of the digging rod 20 is rotatably connected to the hopper 21. A motor A22 is fixedly installed on the surface of the installation plate 18. A gear 23 is fixedly installed at the output end of the motor A22. A hollow gear 24 meshes on the surface of the gear 23. The motor 19 drives the digging rod 20 to rotate, so that the material moves evenly inside the hopper 21 and avoids blockage at the outlet of the hopper 21. Motor A22 drives gear 23, which in turn drives hollow gear 24 to rotate, thereby adjusting the angle of hopper 21. This allows the feeding direction and discharge height to be freely adjusted according to production needs, improving the flexibility of the equipment. The side of hollow gear 24 is fixedly connected to the side of hopper 21, and one side of hollow gear 24 is rotatably connected to the side of vertical plate 17. The side of gear 23 is rotatably connected to the side of vertical plate 17, so that when gear 23 rotates, it can drive hopper 21 to adjust its angle. The rotatable connection between one side of hollow gear 24 and the side of vertical plate 17 ensures that hopper 21 remains stable during adjustment. The rotatable connection between the side of gear 23 and vertical plate 17 ensures smooth adjustment.

[0023] Working principle: The aggregate first enters the device through the hopper 21. The motor A22 drives the gear 23 and hollow gear 24 to rotate, adjusting the angle of the hopper 21 to adapt to different feeding requirements. At the same time, the motor 19 drives the digging rod 20 to rotate, preventing the hopper 21 from clogging and ensuring that the aggregate is discharged evenly. The aggregate then falls onto the filter conveyor belt 12. The motor 10 drives the rotating roller 11 and rotating roller A13 to make the filter conveyor belt 12 roll. During the conveying process, the aggregate is washed by the water sprayer 8, and the mud and dust are cleaned. The mesh conveyor belt 12 achieves synchronous screening during rolling. Qualified aggregates fall onto the screen plate 2 through the filter screen, while larger impurities continue to be discharged with the conveyor belt. The aggregates on the surface of the screen plate 2 are collected by the scraper 3 and discharged into the discharge plate 16, completing the collection and output of aggregates. The water pump 5 realizes water circulation through the water pumping pipe 6 and the conveying pipe 7. The water sprayer 8 continuously provides a source of cleaning water to ensure the cleaning effect. The support roller 14 provides stable support for the filter screen conveyor belt 12 to prevent deformation or loosening and ensure the continuity and stability of conveying and screening.
