[0002] Impurity removal is a crucial step in the preparation of high-strength, durable recycled concrete, aiming to remove impurities from the recycled aggregate to ensure the quality and performance of the final concrete. The primary goal of impurity removal during the preparation of high-strength, durable recycled concrete is to remove the following impurities from the aggregate: Large particles, especially ferrous metals, to prevent these from entering the recycled concrete and affecting its strength and quality. Impurities such as rebar, wood, plastic fragments, glass, and building plaster, if not removed, can reduce the quality of the recycled concrete. Lightweight impurities, such as sawdust, paper scraps, and plastic, can be separated using specialized processing equipment to ensure the purity of the recycled aggregate.

[0003] At present, when removing light impurities, impurities such as leaves contained in large blocks of concrete are generally removed before the initial crushing of the concrete. However, impurities such as wood chips, paper scraps, and plastics will still exist in the crushed concrete. The current method of removing them by water washing not only wastes a lot of water resources, but can only remove light impurities. Some iron impurities require additional equipment to remove. Based on this, a high-strength and durable recycled concrete impurity removal device is proposed. Utility Model Content

It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figures 1-6As shown, a dust removal device for high-strength and durable recycled concrete comprises a dust removal box 1 and a crushing mechanism installed in the dust removal box 1, the crushing mechanism comprises a motor 2 installed on the dust removal box 1 and located on one side of the fan 9, the output end of the motor 2 is fixedly connected to one end of the first crushing roller 3, the other end of the first crushing roller 3 is rotatably connected to the dust removal box 1 and is fixedly connected to the first gear 4, the second crushing roller 6 is rotatably connected to the dust removal box 1, one end of the second crushing roller 6 is fixedly connected to the second gear 5, the second gear 5 and the first gear 4 are meshed with the first crushing roller 3, the first crushing roller 3 is rotatably connected to the dust removal box 1, a fan 9 is installed on one side of the dust removal box 1, a collecting port 10 is opened on the other side of the dust removal box 1, a cleaning component is fixedly connected to the dust removal box 1 on one side of the collecting port 10, a baffle 12 is fixedly connected in the dust removal box 1, the first crushing roller 3 and the second crushing roller 6 are arranged in the baffle 12, the fan 9 and the collecting port 10 are arranged at both ends of the baffle 12, and the cleaning component is used to clean the dust removal box 1 at the fan 9 During operation, the light impurities contained in the crushed concrete are collected. A driving shaft 801 is installed inside the impurity removal box 1, and a magnetic conveyor belt 802 is sleeved on the driving shaft 801. A driven shaft 803 is installed on the side wall of the impurity removal box 1. The driven shaft 803 is adapted to the magnetic conveyor belt 802, and the driving shaft 801 and the driven shaft 803 are both made of non-magnetic material. The cleaning component is also used to scrape off the iron materials adsorbed on the magnetic conveyor belt 802. The end of the second crushing roller 6 away from the second gear 5 is connected to the driving shaft 801 through a transmission assembly. The transmission assembly includes a first sprocket 701 fixedly connected to the end of the second crushing roller 6 away from the second gear 5. A chain 702 is installed on the first sprocket 701. The end of the driving shaft 801 is fixedly connected to the second sprocket 704. The chain 702 is adapted to the second sprocket 704. The impurity removal box 1 is located on one side of the fan 9 and is rotatably connected to a guide wheel 703, which is adapted to the chain 702.

[0023] When in use, start the motor 2 and the fan 9, and then throw the concrete that needs to be cleaned from the top of the cleaning box 1, so that it enters between the first crushing roller 3 and the second crushing roller 6 under the guidance of the baffle 12, and is crushed by the first crushing roller 3 and the second crushing roller 6. Before crushing, due to the operation of the fan 9, the wind generated by the fan 9 will enter the cleaning component through the collection port 10, and then be discharged through the first crushing roller 3 and the second crushing roller 6, acting on the concrete, and removing the light impurities in the concrete that have not been integrated with the concrete. The light impurities contained in the concrete after being crushed by the first crushing roller 3 and the second crushing roller 6 will enter under the action of the wind of the fan 9. In the cleaning component, the concrete after light impurities are removed will fall onto the magnetic conveyor belt 802. Since the rotation of the second crushing roller 6 will drive the driving shaft 801 to rotate through the transmission component, the magnetic conveyor belt 802 will convey the crushed concrete. The iron impurities contained in the crushed concrete will be adsorbed by the magnetic conveyor belt 802. The magnetic conveyor belt 802 conveys the crushed concrete, and the iron impurities will be adsorbed on the magnetic conveyor belt 802. When the magnetic conveyor belt 802 passes through the cleaning component, the cleaning component will remove the iron impurities adsorbed on the magnetic conveyor belt 802. This process is repeated until the concrete that needs to be cleaned is completely processed.

[0024] It realizes the comprehensive and effective removal of light impurities contained in the concrete and light impurities not integrated into the concrete, and removes the iron impurities contained in the concrete, ensuring the efficiency of concrete removal and thus ensuring the purity of the recycled aggregate.

[0025] like Figure 2-Figure 6 As shown, the cleaning component includes a collecting box 1101 fixedly connected to the impurity removal box 1 and located on one side of the collecting port 10, and the collecting box 1101 cover is arranged on the collecting port 10, the interior of the collecting box 1101 is fixedly connected with a dustproof net 1102, the top of the collecting box 1101 is fixedly connected with an air pipe 1103, a collecting box 1104 is installed in the collecting box 1101, and the two sides of the collecting box 1104 are respectively fixedly connected with a handle and a collecting frame 1105, and the collecting frame 1105 is fixedly connected with a scraping part 1106 arranged in an inclined manner, the collecting frame 1105 is located at the bottom of the magnetic conveyor belt 802, and the top of the scraping part 1106 is in contact with the outer surface of the magnetic conveyor belt 802, the first crushing roller 3 and the second crushing roller 6 are both configured to be hollow, and the side walls of the first crushing roller 3 and the second crushing roller 6 configured to be hollow are provided with air injection holes 1107, and the ends of the air pipe 1103 are rotatably connected to the first crushing roller 3 and the second crushing roller 6.

[0026] When in use, the airflow containing light impurities entering the collection box 1101 through the collection port 10 will be filtered under the action of the dustproof net 1102, and the filtered airflow enters the first and second hollow crushing rollers 3 and 6 through the air pipe 1103, and is sprayed into the unbroken concrete through the air jet hole 1107 to remove the light impurities contained in the unbroken concrete. When the magnetic conveyor belt 802 rotates, when the magnetic conveyor belt 802 passes through the collection frame 1105, the light impurities will be removed by the inclined scraping part 110 provided on the collection frame 1105. 6. Scrape off the iron impurities adsorbed on the magnetic conveyor belt 802 to ensure the cleanliness of the magnetic conveyor belt 802, so that the magnetic conveyor belt 802 can adsorb more iron impurities. After the concrete is completely processed, the fan 9 is turned off, which will cause the light impurities in the collection box 1101 to fall into the collection box 1104. Then, the collection box 1104 is pulled out of the collection box 1101 by pulling the handle, and then the light impurities in the collection box 1104 and the iron impurities in the collection frame 1105 are dumped. After the dumping is completed, reinsert them into the collection box 1101.
