[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] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0026] Referring to 1-5, one embodiment of this utility model provides: a pre-wetting treatment device for aggregates in concrete production, including a mixing tank 1, which provides a sealed space for pre-wetting treatment of aggregates. A tank cover 15 is fixedly connected to the top of the mixing tank 1 to prevent dust and water mist from overflowing during mixing and pre-wetting. A feed hopper 3 is fixedly connected to the left side of the tank cover 15, through which larger aggregates are screened using an internal screen 13 to remove large particles and soil. A connecting rod 5 is installed in the middle of the mixing tank 1, transmitting the rotational power of a motor 8 to a mixing rod 2, causing the mixing rod 2 to rotate and thus mix the aggregates. Two mixing rods 2 are fixedly connected to one side of the bottom of the connecting rod 5, ensuring that the aggregates are fully and evenly mixed in the mixing tank 1, guaranteeing sufficient contact between the aggregates and water, and improving the uniformity of pre-wetting. A screen 13 is installed inside the feed hopper 3 to screen out larger aggregates. A vibrating motor 6 is installed on one side of the feed hopper 3, generating vibration to continuously agitate the aggregates on the screen 13, enhancing the screening effect and improving screening efficiency. A scraper 16 is fixedly connected to one side of the top of the rod 5 to scrape the inner wall of the mixing tank 1, remove residual aggregate adhering to the tank wall, prevent aggregate accumulation or clumping, and avoid affecting the pre-wetting effect and normal operation of the equipment. The top of the tank cover 15 is connected to the front and rear sides through and fixedly connected to the mist nozzles 4, which spray water evenly on the surface of the aggregate, so that the aggregate can fully absorb water and achieve precise pre-wetting treatment. The top of the rear mist nozzle 4 is fixedly connected to the main water pipe 9, which is used to transport water from the water tank 11 to the water distribution pipe 14 and the rear mist nozzle 4. The bottom of the inner side of the mixing tank 1 has evenly distributed drainage holes 17, which are used to discharge the wastewater generated during the pre-wetting process into the filter box 19 to prevent wastewater from accumulating in the mixing tank 1. The bottom of the drainage hole 17 is fixedly connected to the filter box 19, which is used to filter the wastewater discharged from the mixing tank 1, intercept impurities such as mud or suspended solids in the wastewater, so that the filtered water can meet the standards for recycling or discharge. A water tank 11 is set at the rear right side of the mixing tank 1 for storing water.

[0027] A motor 8 is fixedly connected to the top of the connecting rod 5, providing power to rotate the scraper 16 and the stirring rod 2. The motor 8 is threadedly connected to the tank cover 15. A water distribution pipe 14 is fixedly connected to the top of the front mist nozzle 4, used to transport water from the main water pipe 9 to the front mist nozzle 4 for spraying. The water distribution pipe 14 is fixedly connected to the main water pipe 9. A water pump 10 is fixedly connected to one end of the main water pipe 9, which draws water from the water tank 11 and transports it to the mist nozzle 4 through the main water pipe 9 and the water distribution pipe 14. The water pump 10 is fixedly connected to the water tank 11. A sliding plate 25 is fixedly connected inside the filter box 19, facilitating the sliding removal of the filter plate 20 from the filter box 19 for cleaning or replacement, ensuring filtration efficiency. The filter plate 20 is slidably connected inside the sliding plate 25 to intercept and filter impurities in the wastewater. The bottom of the filter box 19 is fixedly connected to... A filter pipe 24 is provided to transport filtered water from the filter box 19 to the collection box 18 for storage, realizing the recycling of water resources. A collection box 18 is provided at one end of the filter pipe 24 to collect the water filtered by the filter box 19. A rotating plate 21 is rotatably connected to the right side of the filter box 19 to facilitate maintenance and cleaning of the inside of the filter box 19 by the operator. A locking rod 23 is slidably connected to one side of the rotating plate 21 to fix the rotating plate 21 in place with the locking block 22 so that it does not rotate. A locking block 22 is provided on one side of the filter box 19 to fix the rotating plate 21 in place with the locking rod 23. The locking block 22 and the locking rod 23 are positioned correspondingly. Three support columns 12 are fixedly connected to the bottom of the mixing tank 1 to support the support columns 12 of the mixing tank 1. A discharge pipe 7 is connected through and fixedly connected to the right side of the mixing tank 1 to transport the pre-wetted aggregate out of the mixing tank 1.

[0028] Working principle: The pre-wetted aggregate is poured into the mixing tank 1 through the feed hopper 3. The screen 13 inside the feed hopper 3 performs initial screening of the aggregate. During screening, smaller aggregates and impurities pass through the screen 13 and enter the mixing tank 1, while larger aggregates are intercepted. Simultaneously, the vibration motor 6 is activated, causing the screen 13 to vibrate, thereby improving screening efficiency and ensuring that only aggregates meeting the particle size requirements enter the mixing tank 1. After screening, the aggregate enters the mixing tank 1 through the feed inlet. Then, the motor 8 is activated, rotating the connecting rod 5, which in turn rotates the two middle stirring rods 2, mixing the aggregate thoroughly and evenly within the mixing tank 1. Simultaneously, the scraper 16 at the top of the connecting rod 5 rotates with the connecting rod 5, scraping the inner wall of the mixing tank 1 to prevent aggregate residue from remaining on the tank wall. Start the water pump 10. The water pump 10 draws water from the water tank 11 and then delivers it through the main water pipe 9 to the front mist nozzle 4 and the rear mist nozzle 4 at one end of the distribution pipe 14. The water mist is sprayed evenly on the surface of the aggregate, allowing the aggregate to fully absorb water and achieve precise pre-wetting treatment. The wastewater generated during the pre-wetting process flows into the filter box 19 through the drain hole 17 in the middle of the bottom of the mixing tank 1. The wastewater is then filtered by the filter plate 20. The filtered wastewater flows into the collection box 18 for storage through the filter pipe 24 fixedly connected to the bottom of the filter box 19. When it is necessary to clean or replace the filter plate 20, pull out the locking rod 23 on the right side of the rotating plate 21 of the filter box 19 from the locking block 22 on the side of the filter box 19, open the rotating plate 21, and then slide the filter plate 20 out with the sliding plate 25 to clean or replace the filter plate 20 to ensure the filtration effect.
