However, in existing construction waste magnetic separation processes, efficiently and stably removing the magnetic materials from the magnetic separation rollers after adsorption has become a major technical challenge. Traditional removal methods often suffer from uneven pressure, preventing the scraper from effectively removing magnetic materials from all parts of the magnetic separation roller along its axis, greatly affecting the separation effect and work efficiency of magnetic materials in construction waste. A new technical solution is urgently needed to solve this problem.

This will improve the separation efficiency and quality of magnetic material in construction waste and promote the green and low-carbon treatment of construction waste.

[0050] The present invention will be further described below with reference to the accompanying drawings.

[0051] Reference Figures 1-5 As shown, the green and low-carbon magnetic separation device for construction waste in this embodiment mainly includes the following key components:

[0052] Box 1, as the load-bearing structure of the entire device, provides installation space for internal components and plays a protective role in the construction waste treatment process.

[0053] The magnetic separator 2, rotatably mounted inside the housing 1, is the core component for adsorbing magnetic materials. Through its own magnetism, it effectively adsorbs magnetic materials from construction waste, thus achieving the initial separation of magnetic materials from other construction waste.

[0054] The scraper mechanism 3 is composed of multiple parts working together:

[0055] The first piston cylinder 31 is located on one side of the magnetic separator 2, and its length direction is parallel to its own axis. The first piston cylinder 31 plays a key role in pressure transmission and support in the entire scraper mechanism 3.

[0056] The first piston 32 is slidably mounted inside the first piston cylinder 31, and its sliding direction is perpendicular to the axis of the first piston cylinder 31. This design allows the first piston 32 to move stably along a specific direction under pressure, providing power to the scraper 33.

[0057] The scraper 33 is connected at one end to the first piston 32, and at the other end is used to make close contact with the magnetic separator 2. When the magnetic separator 2 rotates, the scraper 33 can scrape off the magnetic material adsorbed on the surface of the magnetic separator 2, thereby removing the magnetic material.

[0058] An elastic pushing assembly 34 is connected to the first piston cylinder 31. The portion of the first piston cylinder 31 between the first piston 32 and the elastic pushing assembly 34 is filled with hydraulic oil. The elastic pushing assembly 34 continuously pushes the hydraulic oil. Due to the incompressibility of the hydraulic oil, it can evenly transmit pressure to all parts of the first piston 32, thereby ensuring that the first piston 32 drives the scraper 33 to consistently apply uniform pressure to the magnetic separator roller 2. This ensures that the scraper 33 effectively scrapes away magnetic material along the axial direction of the magnetic separator roller 2, avoiding ineffective scraping of magnetic material along the axial direction of the magnetic separator roller 2 due to uneven pressure. Furthermore, even if the scraper 33 wears, the pressure applied by the elastic pushing assembly 34 can be adaptively adjusted to ensure that the scraper 33 continuously contacts the magnetic separator roller 2, maintaining its working condition.

[0059] Furthermore, the elastic pushing component 34 specifically includes:

[0060] The second piston cylinder 341 is connected at one end to and internally communicates with the first piston cylinder 31. The second piston cylinder 341 provides space for the movement of the second piston 342 and together with the first piston cylinder 31, forms a closed hydraulic oil movement space.

[0061] The second piston 342 is slidably mounted inside the second piston cylinder 341. Under the action of the elastic element 343, the second piston 342 can move within the second piston cylinder 341, thereby generating a pushing force on the hydraulic oil.

[0062] Hydraulic oil is evenly filled in the portion of the first piston cylinder 31 and the second piston cylinder 341 located between the first piston 32 and the second piston 342, ensuring that pressure can be transmitted stably and evenly throughout the space. The elastic element 343 continuously pushes the second piston 342 towards the hydraulic oil side, providing a continuous and stable pressure source for the entire system.

[0063] The elastic pushing component 34 is also additionally equipped with:

[0064] A threaded rod 344 has its threads passing through the second piston cylinder 341. By rotating the threaded rod 344, its position within the second piston cylinder 341 can be adjusted.

[0065] The elastic element 343 abuts against the second piston 342 and the threaded rod 344. When the threaded rod 344 is turned, the compressive strength of the elastic element 343 can be changed, thereby flexibly adjusting the pushing force on the second piston 342, ultimately achieving precise control over the contact pressure between the scraper 33 and the magnetic separator roller 2. To facilitate operation of the threaded rod 344, a handle 345 is connected to its outer end. By turning the handle 345, the operator can easily turn the threaded rod 344, improving operational convenience.

[0066] The inner end of the threaded rod 344 is slidably connected to the second piston cylinder 341 via the third piston 346, and the elastic element 343 is tightly abutted between the second piston 342 and the third piston 346. This structural design not only makes the installation of the elastic element 343 more stable, but also prevents dust from entering the working space of the elastic element 343, so as to ensure that the elastic element 343 can stably exert its pushing effect during operation.

[0067] To facilitate observation of the internal working status of the equipment, the second piston cylinder 341 is located on the outside of the housing 1 and is made of transparent material. This allows the operator to directly observe the positional changes of the second piston 342 without opening the equipment.

[0068] On the side of the second piston cylinder 341, there is a scale 3411 extending along the sliding direction of the second piston 342. By reading the scale 3411, the operator can intuitively understand the moving distance of the second piston 342. Since the movement of the second piston 342 is related to the wear and tear of the scraper 33, the operator can indirectly and accurately grasp the degree of wear and tear of the scraper 33, facilitating timely maintenance and replacement.

[0069] Preferably, the elastic element 343 is a helical spring 3431. The helical spring 3431 has good elasticity and stability, and can continuously and stably push the second piston 342 towards the hydraulic oil side, meeting the requirements of long-term stable operation of the equipment.

[0070] To facilitate equipment installation, maintenance, and component replacement, the first piston cylinder 31 is detachably connected to the housing 1. This design allows the first piston cylinder 31 to be quickly and easily removed from the housing 1 when maintenance or component replacement is required.

[0071] Specifically, the portion of the first piston cylinder 31 located on the outer side of the housing 1 is provided with a connecting plate 311, which is securely connected to the housing 1 by multiple bolts. The multiple bolt connection method ensures the stability of the connection and also facilitates disassembly when necessary.

[0072] Working Principle: When construction waste enters the housing 1, the magnetic separator 2 begins to rotate, using its own magnetism to attract magnetic substances from the construction waste. At this time, the elastic element 343 in the elastic pushing assembly 34, such as the helical spring 3431, continuously pushes the second piston 342. After being pushed, the second piston 342 transmits the force to the hydraulic oil filled in the first piston cylinder 31 and the second piston cylinder 341. Due to the incompressibility of the hydraulic oil, it can evenly transmit the pressure to all parts of the first piston 32. Under the uniform pressure of the hydraulic oil, the first piston 32 drives the scraper 33 to consistently apply uniform pressure to the magnetic separator 2. As the magnetic separator 2 continues to rotate, the scraper 33 can effectively scrape off the magnetic substances adsorbed on the surface of the magnetic separator 2 axially, thereby achieving efficient separation of magnetic substances from construction waste.

[0073] During actual operation, as the scraper 33 wears down, the distance between it and the magnetic separator 2 changes. The elastic pushing component 34 adaptively adjusts the pushing force on the hydraulic oil to ensure that the scraper 33 always remains in contact with the magnetic separator 2, maintaining the normal operation of the equipment. Simultaneously, the operator can rotate the handle 345 to turn the threaded rod 344 according to the characteristics of the magnetic materials in the construction waste and the required separation effect. The rotation of the threaded rod 344 adjusts the compression strength of the elastic element 343, changing the pushing force of the elastic element 343 on the second piston 342, thereby adjusting the contact pressure of the scraper 33 on the magnetic separator 2 to adapt to different working conditions. Furthermore, the operator can indirectly assess the wear and tear of the scraper 33 by reading the scale 3411 on the side of the second piston cylinder 341 and the movement distance of the second piston 342, allowing for advance planning of maintenance and replacement work and ensuring the continuous and stable operation of the equipment.

[0074] This utility model discloses a green and low-carbon magnetic separation device for construction waste. In the key scraper mechanism, the first piston cylinder, the first piston, and the scraper work together. The elastic pushing component, utilizing the incompressible nature of hydraulic oil, evenly transmits pressure to all parts of the first piston, causing the scraper to apply uniform pressure to all parts of the magnetic separation roller along its axis, ensuring effective removal of magnetic materials and solving the problem of uneven pressure application in traditional methods. Even if the scraper wears, this component can adaptively adjust the pressure to maintain contact between the scraper and the magnetic separation roller. The elastic pushing component allows for precise adjustment of the contact pressure via a threaded rod and handle. The transparent design and graduations of the second piston cylinder facilitate operator observation of the equipment status and scraper wear, enabling timely maintenance. The rational design of each component of the device efficiently solves the problems in the prior art and powerfully promotes the green and low-carbon process of construction waste treatment.
