Description

Technical Field

[0001] This utility model relates to the field of recycled aggregate repair technology, and in particular to a pretreatment device for high-temperature damage repair of recycled aggregate. Background Technology

[0002] Recycled aggregate refers to aggregates obtained by recycling, processing, and reusing construction waste. After certain processing, it is reused in new building materials. This not only reduces resource consumption but also minimizes the environmental impact of construction waste, promoting sustainable development. High-temperature damage to recycled aggregate refers to the changes in the physical and chemical properties of recycled aggregates under high-temperature environments, leading to a decrease in their performance. Repair pretreatment equipment refers to equipment used before repair work begins to perform preliminary treatments, cleaning, impurity removal, and condition adjustments on the object to be repaired. It is typically used in materials and structures requiring restoration and repair to ensure that subsequent repair work can proceed smoothly and achieve optimal results.

[0003] A search revealed Chinese patent publication number CN218133577U, which discloses a pretreatment device for recycled aggregates. The device includes a treatment box with two inlets on its upper surface. A partition is fixed between the left and right side walls of the inner cavity of the treatment box, and a discharge pipe is connected to the lower surface of the partition. A water outlet pipe is connected to the right end of the treatment box. The treatment box contains both a drying mechanism and a cleaning mechanism. The drying mechanism includes an air box fixed to the lower surface of the treatment box, a fan fixed to the lower surface of the air box, and a mounting bracket fixed to the left side wall of the air box's inner cavity. This pretreatment device for recycled aggregates, by incorporating a drying mechanism, ensures timely drying of the washed recycled aggregates, thereby accelerating further processing and improving work efficiency. The cleaning mechanism ensures thorough cleaning of the recycled aggregates within the treatment box, preventing insufficient cleaning from affecting subsequent processing.

[0004] Although the aforementioned patents enable timely drying of the cleaned recycled aggregates by setting up a drying mechanism, thereby accelerating the further processing of the recycled aggregates, the processing steps are too simple, resulting in residual impurities on the aggregates that have not been treated. Therefore, in order to address the above shortcomings, a pretreatment device for high-temperature damage repair of recycled aggregates is proposed to solve the above problems. Utility Model Content

[0040] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a pretreatment device for high-temperature damage repair of recycled aggregate, including a base 1, which is the basic component of the entire device.

The rotating shaft 3503 drives the fixed columns 3504 to rotate, thereby realizing the mixing of recycled aggregate and the removal of impurities.

[0043] Specifically, the processing effect of recycled aggregate is effectively improved by removing component 35. The protective shell 3501 of component 35 protects the internal components and is fixedly connected to the outside left side of the fixed cavity 31. Motor 3502 provides stable power output, driving the rotating shaft 3503 to drive multiple fixed columns 3504 to rotate, thereby realizing the mixing and impurity removal of recycled aggregate, ensuring the purity of aggregate in the repair process, improving repair quality, and enhancing processing efficiency.

[0044] A cooling plate 36 is fixedly connected inside the fixed cavity 31. A dispersion component 37 is fixedly connected to the top of the fixed cavity 31. The dispersion component 37 includes a protective shell 3701, which is a rectangular box for protecting the internal components.

Multiple second rotating shafts 3703 are fixedly connected to the outside of the second motor 3702, which rotate under the drive of the second motor 3702 and transmit the rotational force. The outside of the second rotating shafts 3703 is rotatably connected to the inside of the fixed cavity 31. The inside of the fixed cavity 31 is rotatably connected to the outside of the first rotating shaft 3503. A circular plate 3704 is fixedly connected to the bottom of the second rotating shaft 3703. An inclined column 3705 is fixedly connected to the bottom of the circular plate 3704. The second rotating shaft 3703 drives the circular plate 3704 and the inclined column 3705 to rotate, thereby realizing the dispersion treatment of recycled aggregate.

[0045] Specifically, the dispersion component 37 effectively improves the processing efficiency of recycled aggregate. The protective shell 3701 of the dispersion component 37 protects the internal components. The second motor 3702 provides stable power output, driving the second rotating shaft 3703 to rotate. The second rotating shaft 3703 transmits the rotational power to the circular plate 3704 and the inclined column 3705. Through rotation, the circular plate and the inclined column achieve the dispersion processing of recycled aggregate, avoiding aggregate agglomeration and ensuring uniformity in the repair process. The cooling plate 36 set inside the fixed cavity 31 helps to control the temperature and avoid the impact of overheating on the aggregate, effectively improving the processing efficiency of the equipment and the quality of aggregate repair.

[0046] A liquid storage tank 38 is fixedly connected to the top of the fixed cavity 31. The liquid storage tank 38 is a rectangular box for storing coolant. A water pumping assembly 39 is fixedly connected to the bottom of the liquid storage tank 38. The water pumping assembly 39 includes a water pump 3901, which can provide a stable water flow. The top of the water pump 3901 is fixedly connected to the bottom of the liquid storage tank 38. A water pipe 3902 is fixedly connected to the drive end of the water pump 3901. A nozzle 310 is fixedly connected to the bottom of the water pumping assembly 39. The water pipe 3902 delivers coolant to the nozzle 310 for spraying and cooling the recycled aggregate.

[0047] Specifically, the recycled aggregate is effectively cooled by the storage tank 38 and the pumping assembly 39. The storage tank 38 is used to store coolant, and the water pump 3901 provides a stable water flow, which delivers the coolant to the nozzle 310 through the water pipe 3902. The nozzle 310 sprays the recycled aggregate evenly to cool it, effectively controlling the temperature and preventing overheating from affecting the aggregate repair effect. This ensures the temperature stability of the aggregate during the repair process, improves the processing efficiency, and helps protect the physical properties of the aggregate, thereby improving the repair quality.

[0048] Reference Figure 3 and Figure 4 The base 1 has multiple support columns 4 fixedly connected to its top for supporting the screening mechanism 5. The screening mechanism 5 includes a spring 51, which provides stable elastic support and drives the connecting plate 53 to vibrate. One end of the spring 51 is fixedly connected to the top of the support column 4, and the other end of the spring 51 is fixedly connected to a fixing plate 52. The fixing plate 52 is rectangular and is used to connect the fixing plate 52 and the connecting plate 53. The connecting plate 53 is fixedly connected to the outside of the multiple fixing plates 52. A primary filter plate 54 is fixedly connected to the inside of the connecting plate 53. A secondary filter plate 55 is fixedly connected to the inside of the connecting plate 53. The primary filter plate 54 and the secondary filter plate 55 are rectangular and have circular holes of different diameters on their surfaces for screening recycled aggregates of different diameters.

[0049] Specifically, the spring 51 provides stable elastic support, enabling the screening mechanism 5 to vibrate effectively, thereby improving screening efficiency. Multiple support columns 4 support the screening mechanism 5. The fixing plate 52 and connecting plate 53 fix the primary filter plate 54 and the secondary filter plate 55 in appropriate positions. The different diameter circular hole design of the primary and secondary filter plates 55 enables them to accurately screen recycled aggregates of different diameters and separate aggregates that meet the requirements.

[0050] A vibration assembly 56 is fixedly connected to the top of the base 1. The vibration assembly 56 includes a support plate 5601, which is rectangular in shape. The bottom of the support plate 5601 is fixedly connected to the top of the base 1. A motor 5602 is fixedly connected to the top of the support plate 5601, which can provide stable power output. A rotating shaft 5603 is fixedly connected to the drive end of the motor 5602. The shaft rotates under the drive of the motor 5602 and transmits force. The rotating shaft 5603 is fixedly connected to an eccentric wheel 5604. Through the rotation of the eccentric wheel 5604, the impact plate 5605 can generate vibration, which drives the screening mechanism 5 to perform vibratory screening and improves screening efficiency. The impact plate 5605 is slidably connected to the outside of the eccentric wheel 5604. The impact plate 5605 is fixedly connected to the outside of the connecting plate 53 on the left side.

[0051] Specifically, the rotating shaft 5603 is driven by motor 5602, which in turn drives the eccentric wheel 5604 to rotate, thereby generating vibration. The eccentric wheel 5604 is connected to the impact plate 5605, causing the impact plate 5605 to continuously impact during rotation, thus providing vibration to the screening mechanism 5, improving screening efficiency. The vibration promotes the efficient operation of the screening mechanism 5, ensuring that recycled aggregates of different diameters are fully screened, separating out aggregates that meet the requirements, enhancing screening efficiency, improving the equipment's ability to process recycled aggregates, and helping to improve the utilization rate and quality of aggregates.

[0052] A collection component 57 is fixedly connected to the top of the base 1. The collection component 57 includes a collection box 5701. The collection box 5701 is rectangular in shape and divided into three spaces, so that aggregates of different diameters can be placed in one space. The bottom of the collection box 5701 is fixedly connected to the top of the base 1. Multiple fixed filter plates 5702 are fixedly connected to the upper part of the inside of the collection box 5701. The fixed filter plates 5702 are rectangular in shape and have holes on them for further filtering of the screened recycled aggregates to prevent aggregates that do not meet the diameter requirements from entering the collection box 5701.

[0053] Specifically, aggregates of different diameters are classified and stored in collection box 5701. Collection box 5701 is divided into three spaces, and the screened aggregates are placed according to their diameter. Fixed filter plate 5702 is located at the upper part of the inside of collection box 5701. The surface is provided with holes for further filtering of aggregates, ensuring that aggregates that do not meet the diameter requirements will not enter collection box 5701. This effectively improves the accuracy of aggregate classification, avoids the mixing of unqualified aggregates, and ensures that the screened aggregates can be stored according to specifications, which helps to improve the utilization value of recycled aggregates and the efficiency of subsequent processing.

[0054] Working principle: After the recycled aggregate is fed into the conveyor belt 2 through the feed hopper 32, it is first transported to the heating zone formed by two partitions 33. Under the high temperature of the heating wire 34, surface impurities are removed. At the same time, the motor 3502 drives the rotating shaft 3503 to rotate, so that the fixed column 3504 outside the rotating shaft 3503 stirs and impacts the heated aggregate, further treating the surface of the aggregate. The heated aggregate then enters the cooling plate 36 area of ​​the fixed cavity 31 for rapid cooling. The cooled aggregate is dispersed by the circular plate 3704 and inclined column 3705 driven by the rotating shaft 3703. After being evenly spread, it is transported to the area below the nozzle 310. At this time, the repair liquid in the storage tank 38 is pressurized by the water pump 3901 and transported to the nozzle 310 through the water pipe 3902 to precisely spray and fill the micro-cracks on the surface of the aggregate.

[0055] The repaired aggregate falls from the end of the conveyor belt 2 onto the surface of the connecting plate 53. The motor 3 5602 drives the rotating shaft 3 5603 to rotate the eccentric wheel 5604. The periodic impact of the impact plate 5605 generates vibration, causing the connecting plate 53 to form a vibrating screen under the support of the spring 51. Thus, the aggregate passes through the primary filter plate 54 and the secondary filter plate 55 with decreasing apertures in sequence to classify the particle size. Finally, the aggregates of different particle sizes fall into the three independent chambers of the collection box 5701. The fixed filter plate 5702 at the top of the collection box 5701 performs secondary filtration on the classified aggregates to prevent the aggregates from splashing into different chambers.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
