Description

Technical Field

[0001] The utility model relates to the field of waste concrete recycling, and particularly relates to a device for extracting and recycling waste concrete raw materials. Background Art

[0002] Waste concrete refers to the waste concrete materials generated during construction, demolition or maintenance. Treating waste concrete is an important environmental protection task because a large amount of waste concrete will occupy land resources and have a negative impact on the environment. A device for extracting and recycling waste concrete raw materials is needed during the process of extracting and recycling waste concrete raw materials.

[0003] In the prior art, as disclosed in the publication number CN215465010U, a device for extracting and recycling waste concrete raw materials for construction is disclosed, which relates to the technical field of extracting and recycling waste concrete raw materials. It includes a recycling box (1). On one side of the front and rear ends of the recycling box (1), moving mounting plates (5) are installed. The moving mounting plates (5) are connected to the recycling box (1) through card slots. There are two moving mounting plates (5). A first crushing roller (7) is installed between the two moving mounting plates (5). By installing the moving mounting plates, the first crushing roller can move horizontally under the action of the adjusting push rod, which is convenient for workers to adjust the distance between the first crushing roller and the second crushing roller according to the size of the material, ensuring the crushing effect of the material. At the same time, when there is material stuck inside the device, the material can be discharged to avoid material blockage of the device, increasing the practicability of the device. Installing the first crushing roller and the second crushing roller can quickly crush the material, facilitating the recycling of the material for secondary use, avoiding waste and environmental pollution.

[0004] However, there are still some problems with this device. Among them, by installing the first crushing roller and the second crushing roller, the material can be quickly crushed, facilitating the recycling of the material for secondary use. In the actual application process, although the waste concrete is crushed and collected, due to the complex composition of the waste concrete, even after the crushing and collection treatment, the raw materials in the concrete are still not classified and extracted and recycled, resulting in a poor recycling quality problem. Therefore, we disclose a device for extracting and recycling waste concrete raw materials to meet people's needs. Summary of the Utility Model

[0023] Based on the above structure, the crushing roller 2 is divided into a main roller and a secondary roller. The main roller is mainly driven to rotate by a drive, and then the secondary roller is driven to rotate through gear cooperation so that they move and crush simultaneously. At the same time, the back surface of the main roller extends outside the crushing box 1 and is connected with a drive disk 9.

[0024] As Figure 2 、 4 shown, a driving hole is opened on the back surface of the crushing box 1. The back surface of the crushing roller 2 extends outside the crushing box 1 through the driving hole. A drive disk 9 is fixedly connected to the back surface of the crushing roller 2. The extraction component 8 includes a transmission rod 81 rotatably connected to the inner wall of the transmission hole. A transmission disk 82 is fixedly connected to the back surface of the transmission rod 81. The same transmission belt 10 is sleeved on the surfaces of the transmission disk 82 and the drive disk 9.

The water enters the branch pipe 87 through the shunt pipe 86 and is then sprayed out through the high-pressure spray head 89 to wash the sand and gravel in the filter plate 85, removing the surface impurities and dust, and flowing into the bottom of the elutriation box 7 through the filter holes. After the washing is completed, the device is turned off, and the large particle collection box 6 and the filter plate 85 are removed respectively to obtain pure sand and gravel raw materials and crushed stone raw materials, improving the recycling quality of waste concrete.
