Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete processing technology, and in particular to an aggregate processing device for commercial concrete processing. Background Technology
[0002] In the production of ready-mixed concrete, aggregates are one of the main components of concrete, usually composed of inorganic substances such as sand and stone. The quality of aggregates directly affects the performance of concrete and the final building quality. Therefore, the aggregate processing is crucial, especially the cleaning and screening of raw materials. Effectively removing impurities, mud, dust and other unqualified substances from aggregates is an important step in ensuring concrete quality.
[0003] Existing cleaning devices use clean water tanks and nozzles to spray and clean the surface of aggregates. However, thick layers of dirt accumulated on the surface of aggregates cannot be sprayed and cleaned in time, which has limitations and reduces the cleaning effect of aggregates used in concrete production. Existing patent (publication number: CN222288135U) describes a concrete aggregate cleaning equipment, including a cleaning body. The top of the cleaning body is equipped with a cleaning component for soaking concrete aggregates, facilitating the removal of dirt after stirring and achieving thorough cleaning. The bottom of the cleaning body is equipped with a scraper component for filtering and discharging residual dirt after cleaning the concrete aggregates, improving the purity of the cleaning water. The cleaning component includes a semi-circular filter cylinder located at the top of the cleaning body. The two sides of the semi-circular filter cylinder are connected to the same rotating shaft via bearings. This invention uses two arc-shaped limiting plates to agitate the concrete aggregates inside the semi-circular filter cylinder, facilitating full contact between the concrete aggregates and the cleaning water. This allows dirt to be removed after soaking in the cleaning water, thus facilitating thorough removal of dirt from the concrete aggregates and improving the cleaning effect.
[0004] To address the aforementioned issues, existing patents have provided solutions, but these solutions cannot filter and clean impurities inside the aggregates during the washing process. Additionally, existing washing tanks are not convenient for cleaning sludge and impurities at the washing area.
[0005] Therefore, an aggregate processing device for commercial concrete processing is proposed. Utility Model Content

[0020] 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.
[0021] Please see Figures 1 to 5 This utility model provides a technical solution: An aggregate processing device for commercial concrete processing includes a washing tank 1, two sets of washing pipes 2 are provided at the top of the washing tank 1, multiple washing nozzles 3 are provided at the bottom of the washing pipes 2, a conveying and screening mechanism 4 is provided in the middle of the washing tank 1, and a cleaning mechanism 5 is provided at the bottom of the washing tank 1. The conveying and screening mechanism 4 includes a conveying cover 41 installed inside the washing tank 1. The conveying cover 41 has a U-shaped cross-section. A conveying shaft 42 is installed inside the conveying cover 41. A conveying spiral blade 43 is installed on the side wall of the conveying shaft 42. Two sets of screening screens 44 are installed at the bottom of the conveying cover 41. A drive motor 45 is bolted to the side wall of the conveying cover 41. The output end of the drive motor 45 is fixedly connected to the conveying shaft 42.
[0022] Specifically, such as Figure 4 As shown, the bottom of the cleaning tank 1 is inclined, and the bottom of the cleaning tank 1 is inclined towards the convex tube 51.
[0023] Specifically, such as Figure 4 As shown, a cleaning pipe 6 is provided on the side wall of the cleaning tank 1, a filter tank 7 is provided at the bottom of the cleaning pipe 6, a filter screen 8 is provided inside the filter tank 7, and a water pump 9 is provided on one side of the filter tank 7. The input end of the water pump 9 is fixedly connected to the filter tank 7.
[0024] Specifically, such as Figure 4 As shown, a sedimentation tank 10 is provided on one side of the filter tank 7, and a delivery pipe 11 is fixedly connected to the output end of the water pump 9. The delivery pipe 11 is located inside the sedimentation tank 10.
[0025] Specifically, such as Figure 3 As shown, a feed hopper 12 is provided on the side wall of the washing tank 1 and the conveying cover 41. The side wall of the feed hopper 12 is inclined. The other end of the conveying cover 41 extends to the outside of the washing tank 1. A discharge pipe 13 is provided at the bottom of the conveying cover 41.
[0026] Specifically, such as Figure 4 As shown, a drain pipe 14 is provided at one end of the convex pipe 51, and a cap 15 is provided at the bottom of the drain pipe 14.
[0027] In operation, aggregates enter the conveying hood 41 inside the washing tank 1 through the feed hopper 12. The side walls of the feed hopper 12 are inclined to facilitate the smooth sliding of aggregates. At this time, the two sets of washing pipes 2 at the top of the washing tank 1 start working. Multiple washing nozzles 3 at the bottom of the washing pipes 2 spray high-pressure water into the washing tank 1 to thoroughly wash the aggregates in the conveying hood 41, removing mud, impurities, etc. attached to the surface of the aggregates. The drive motor 45 starts, and its output end drives the conveying shaft 42 to rotate. The conveying spiral blades 43 on the side wall of the conveying shaft 42 rotate accordingly. During the rotation of the conveying spiral blades 43, the aggregates are pushed forward to achieve the conveying of aggregates. During the conveying process, small particles and wastewater mixed in with the aggregates will fall through the two sets of screens 44 at the bottom of the conveying hood 41 and enter the bottom of the washing tank 1. The aggregates continue to be pushed by the conveying spiral blades 43 to the end of the conveying hood 41 that extends outside the washing tank 1, and finally are discharged through the discharge pipe 13, completing the screening and conveying process. At the same time, the cleaning... The impurity removal pipe 6 on the side wall of the washing tank 1 starts working. Under the suction of the water pump 9, the sewage enters the filter tank 7 from the impurity removal pipe 6. The filter screen 8 in the filter tank 7 performs preliminary filtration of the sewage, intercepting larger impurity particles. The sewage that has passed the preliminary filtration is then pumped by the water pump 9 and transported to the sedimentation tank 10 through the conveying pipe 11. Further sedimentation treatment is carried out in the sedimentation tank 10 to settle the fine impurities in the sewage, thereby purifying the sewage for subsequent recycling or discharge in compliance with standards. In this way, through the setting of the conveying and screening mechanism 4, the high-pressure washing of the cleaning nozzle 3 and the pushing and conveying of the conveying spiral blade 43 are combined to achieve the washing and screening of aggregates while conveying them. The cleaning nozzle 3 can wash the aggregates in all directions to ensure that impurities on the surface of the aggregates are effectively removed. The continuous pushing of the conveying spiral blade 43 ensures the conveying efficiency of the aggregates, and the screening screen 44 can separate sewage and impurities in a timely manner, improving the quality and efficiency of aggregate washing and screening.
[0028] Specifically, such as Figure 4 and Figure 5As shown, the cleaning mechanism 5 includes a protruding tube 51 disposed at the bottom of the cleaning tank 1, a cleaning shaft 52 connected to the middle bearing of the protruding tube 51, a cleaning spiral blade 53 disposed on the side wall of the cleaning shaft 52, and a power transmission assembly 54 disposed at one end of the cleaning shaft 52 and the conveying shaft 42.
[0029] Specifically, such as Figure 5 As shown, the power transmission assembly 54 includes a transmission wheel 541 disposed at one end of the cleaning shaft 52 and the conveying shaft 42. An electric push rod 542 is bolted to the side wall of the cleaning tank 1. An adjusting wheel 543 is disposed at the output end of the electric push rod 542. A transmission belt 544 is disposed between the adjusting wheel 543 and the two transmission wheels 541.
[0030] In use, the output end of the electric push rod 542 extends, pushing the adjusting wheel 543 to move. Under the action of the electric push rod 542, the adjusting wheel 543 moves to a suitable position, forming an effective power transmission path between the adjusting wheel 543 and the transmission wheel 541 at one end of the cleaning shaft 52 and the conveying shaft 42 via the transmission belt 544. Since the conveying shaft 42 rotates continuously under the drive of the drive motor 45, power is transmitted to the cleaning shaft 52 through the transmission wheel 541 and the transmission belt 544. The cleaning shaft 52, now powered, begins to rotate. The cleaning spiral blades 53 on the side wall rotate accordingly. Because the bottom of the washing tank 1 is inclined towards the convex pipe 51, the wastewater and impurities generated during aggregate washing and screening will naturally collect at the convex pipe 51 at the bottom of the washing tank 1. The rotating cleaning spiral blades 53 can push the impurities and sediments collected at the convex pipe 51 forward along the convex pipe 51, and finally discharge them through the drain pipe 14 at one end of the convex pipe 51, thus cleaning the bottom of the washing tank 1. When it is not necessary to clean the bottom of the washing tank 1, the output end of the electric push rod 542 retracts, driving the adjustment The movement of the spur wheel 543 loosens the transmission belt 544 between the adjusting wheel 543 and the transmission wheel 541, cutting off the power transmission between the cleaning shaft 52 and the conveying shaft 42. The cleaning spiral blade 53 stops rotating, and the cleaning work is paused. The cleaning mechanism 5 can be flexibly started or stopped by the precise control of the position of the adjusting wheel 543 by the electric push rod 542 to adapt to different production needs. In this way, the cleaning mechanism 5 can continuously and effectively push the impurities and sediments accumulated at the bottom of the cleaning tank 1 out of the drain pipe 14 by the rotation of the cleaning spiral blade 53, avoiding the long-term accumulation of impurities at the bottom of the cleaning tank 1. The power transmission assembly 54, composed of the electric push rod 542, adjusting wheel 543, transmission wheel 541 and transmission belt 544, realizes the flexible transmission and cut-off of power between the cleaning shaft 52 and the conveying shaft 42. The electric push rod 542 can precisely control the position of the adjusting wheel 543, thereby conveniently controlling the state of the transmission belt 544, so that the cleaning mechanism 5 can start or stop working at any time according to the actual production situation, improving the reliability and flexibility of power transmission and reducing unnecessary energy loss.
[0031] By adopting the above technical solution, the problem that existing aggregate washing equipment for concrete production cannot filter and clean impurities inside the aggregate while washing it is solved, and the problem that the existing washing tank 1 is not convenient for cleaning sludge and impurities at the washing area is solved.
[0032] Working Principle: In use, aggregates first enter the conveyor hood 41 within the washing tank 1 through the feed hopper 12. Multiple cleaning nozzles 3 at the bottom of the washing pipe 2 spray high-pressure water into the washing tank 1, thoroughly rinsing the aggregates in the conveyor hood 41. The drive motor 45 starts, and its output drives the conveyor shaft 42 to rotate. The conveying spiral blades 43 on the side wall of the conveyor shaft 42 rotate accordingly. During rotation, the conveying spiral blades 43 push the aggregates forward. Small particles and wastewater mixed in the aggregates pass through the two sets of screens 44 at the bottom of the conveyor hood 41 and enter the bottom of the washing tank 1. The aggregates continue to be pushed by the conveying spiral blades 43 to the end of the conveyor hood 41 extending outside the washing tank 1, and finally discharged through the discharge pipe 13, completing the screening and conveying process. After washing, the output end of the electric push rod 542 extends, pushing the adjusting wheel 543 to move. The adjusting wheel 543... The push rod 542 moves to a suitable position, so that the adjusting wheel 543 and the transmission wheel 541 at one end of the cleaning shaft 52 and the conveying shaft 42 form an effective power transmission path through the transmission belt 544. Since the conveying shaft 42 rotates continuously under the drive of the drive motor 45, the power is transmitted to the cleaning shaft 52 through the transmission action of the transmission wheel 541 and the transmission belt 544. The cleaning shaft 52, which has obtained power, starts to rotate, and the cleaning spiral blade 53 on the side wall of the cleaning shaft 52 rotates accordingly. Because the bottom of the cleaning tank 1 is set to be inclined towards the convex pipe 51, the sewage and impurities generated during the aggregate washing and screening process will naturally gather at the convex pipe 51 at the bottom of the cleaning tank 1. The rotating cleaning spiral blade 53 can push the impurities and sediments gathered at the convex pipe 51 forward along the convex pipe 51, and finally discharge them through the sewage pipe 14 at one end of the convex pipe 51, thereby cleaning the bottom of the cleaning tank 1.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
