Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a concrete aggregate cleaning device. Background Technology

[0002] During the concrete production process, it is necessary to clean the surface of aggregates such as sand and stone to remove mud, dust and impurities, thereby improving the cleanliness of the aggregates and ensuring the quality of concrete. Traditional aggregate cleaning methods, such as manual washing, are inefficient and consume a lot of water.

[0003] The prior art, disclosed in patent document CN223043211U, presents the following technical solution: a concrete aggregate cleaning device, comprising a feeding box and a cleaning box. A feeding port is fixedly installed on the top of the feeding box. A rolling shaft is rotatably installed inside the feeding box, and a roller is fixedly installed outside the rolling shaft. An air outlet is opened on one side of the feeding box, and an air outlet pipe is fixedly installed on one side of the air outlet. An air inlet pipe is fixedly installed on one side of the feeding box, and a fixing frame is fixedly installed inside the air inlet pipe. A motor is fixedly installed on one side of the fixing frame.

[0004] The above-mentioned technical solution relies on fans to remove surface dust from aggregates, and the aggregates are then directly discharged through a conveyor belt after entering the washing tank. This results in the inability to remove dirt and adhering substances from the gaps in the aggregates, leading to poor cleaning results. In addition, the inclined conveyor belt discharges the aggregates directly, resulting in high moisture content in the aggregates, which affects the mix proportions in subsequent concrete processing.

The bottom side of the cleaning tank 1 is provided with an inclined panel 11, which facilitates the discharge of wastewater and sludge from the drain pipe 12. The outer surface of the cleaning tank 1 near the lower end of the inclined panel 11 is provided with a drain pipe 12, and a valve is provided on the drain pipe 12. An aggregate pretreatment device 2 is bolted to one end of the cleaning tank 1. A hollow conveyor belt mechanism 3 is installed inside the cleaning tank 1. The hollow conveyor belt mechanism 3 is inclined, and the lower end of the hollow conveyor belt mechanism 3 is located below the aggregate pretreatment device 2, while the higher end extends to the outside of the cleaning tank 1.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, the aggregate pretreatment device 2 includes a treatment cylinder with a discharge pipe 21 at the bottom and a valve on the discharge pipe 21. An L-shaped baffle 13 is fixedly connected to the inner wall of the washing tank 1 near the discharge pipe 21. The treatment cylinder is bolted to one end of the washing tank 1. A cover plate 22 is connected to the top flange of the treatment cylinder. A feed channel 221 is provided on one side of the cover plate 22, and a suction fan 222 is provided on the other side of the cover plate 22. The suction fan 222 is connected to an external dust collection box through a pipe. A hollow rotating rod 23 is connected to the middle of the cover plate 22 through a bearing. The hollow rotating rod 23 extends to the lower part of the interior of the treatment cylinder. Nylon brush groups 27 are arranged on the outer wall of the hollow rotating rod 23. Two adjacent nylon brush groups 27... Air nozzles 28 are arranged in a circumferential direction between the 7. The air nozzles 28 adopt a 15° inclined design. A driven gear 24 is sleeved on the outer wall of the upper end of the hollow rotating rod 23. A driving gear 25 is connected to one side of the driven gear 24. A motor 26 is installed on the upper end of the driving gear 25. An air supply pipe 29 is provided at the top of the hollow rotating rod 23 through a bearing. The air supply pipe 29 is connected to an external air pump. By setting a rotating nylon brush group 27 and air nozzles 28 in the processing cylinder, the nylon brush group 27 removes impurities attached to the surface of the aggregate by friction, and the air nozzles 28 blow off loose impurities by pulse airflow, thereby reducing the gaps or attached impurities in the aggregate and improving the cleaning effect.

[0030] like Figure 2 and Figure 3 As shown, spray pipes 4 are arranged on the inner wall of the washing tank 1 near the aggregate pretreatment device 2. There are at least three sets of spray pipes 4. Each spray pipe 4 has a high-pressure nozzle 5 at its lower water outlet. The front end of the spray pipe 4 is fixedly connected to a main water pipe 6, which is connected to an external water tank. The high-pressure nozzles 5 at the bottom of the two side spray pipes 4 are inclined and symmetrically arranged, while the high-pressure nozzles 5 at the bottom of the middle spray pipe 4 are vertically arranged. With multiple sets of spray pipes 4 and high-pressure nozzles 5, and the pressure range of the high-pressure nozzles 5 being 0.8-1.5MPa, it can effectively peel off the attached soil and achieve efficient cleaning.

[0031] like Figure 2 and Figure 3As shown, a bracket 7 is installed above the end of the washing tank 1 away from the aggregate pretreatment device 2 by screws. Fans 8 are installed at both ends of the bracket 7. A heating component 9 is installed inside the bracket 7 and is located below the fan 8. A perforated conveyor belt is set up so that the aggregate conveyed out can be drained through the perforated design after rinsing. The fan 8 and heating component 9 can dry the washed aggregate and reduce the moisture content of the aggregate.

[0032] This utility model provides a concrete aggregate cleaning device, the specific working principle of which is as follows: The aggregate for concrete production is poured into the processing cylinder through the feeding channel 221. Simultaneously, the motor 26 is started, driving the drive gear 25 and driven gear 24 to rotate, causing the hollow rotating rod 23 to rotate, which in turn drives the nylon brush assembly 27 and the air nozzle 28 to rotate. At the same time, an external air pump delivers airflow through the air supply pipe 29 into the hollow rotating rod 23, which is then sprayed out from the air nozzle 28. The nylon brush assembly 27 removes impurities adhering to the surface of the aggregate through friction, while the air nozzle 28 blows away loose material with pulsed airflow. The pretreatment process removes impurities, thus reducing gaps or adhering impurities in the aggregate. During the pretreatment process, dust can be discharged by the suction fan 222. After a period of pretreatment, the valve on the discharge pipe 21 can be automatically opened, allowing the aggregate to fall onto the hollow conveyor belt mechanism 3. When the conveyed aggregate is located below the high-pressure nozzle 5, the adhering soil is peeled off by high-pressure washing, achieving efficient cleaning. During the aggregate conveying process, water is drained through the hollow design. When it is conveyed to the vicinity of the support 7, it is dried by the fan 8 and the heating component 9 to reduce the moisture content of the aggregate until the aggregate is discharged, completing the cleaning process.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
