Description
Technical Field
[0001] This utility model relates to the technical field of steel impurity removal, and in particular to a fine screening device for separating steel impurities. Background Technology
[0002] Steel recycling generally requires crushing and separation to separate the steel. Since steel is a ferromagnetic material, it can be attracted by a magnetic field, while plastic or other impurities such as dust are non-magnetic materials. They are usually screened by a magnetic separator. In use, the mixture of steel and impurities is passed through the magnetic field area of the magnetic separator. The steel is adsorbed onto the magnetic roller, thus achieving separation from the impurities. This method is simple and efficient. Therefore, a fine screening device for steel impurity separation is needed.
[0003] Existing steel impurity separation and fine screening devices only use simple magnetic adsorption to remove steel impurities during screening. However, some smaller impurities are still adsorbed on the surface of the steel and mixed with it. For this type of adsorbed steel, more processing steps are required, which is quite troublesome. Utility Model Content

Detailed Implementation
[0019] 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.
[0020] Please see Figure 1-5 This utility model provides a technical solution: a fine screening device for separating steel impurities, including a fixed frame 1, with magnetic rollers 2 connected to both ends of the fixed frame 1 by bearings, a conveyor belt 3 connected to the outer surface of the magnetic rollers 2, a receiving plate 4 fixedly installed at one end of the fixed frame 1, a hopper 5 fixedly installed on one side of the fixed frame 1, a scraper 6 fixedly installed at one end of the hopper 5, a support frame 7 fixedly installed on one side of the fixed frame 1, a cylinder 8 fixedly installed on one side of the surface of the support frame 7, a drive motor 9 fixedly installed on one end of the surface of the cylinder 8, a spiral blade 10 fixedly installed at the output end of the drive motor 9, a water tank 11 fixedly installed on the upper surface of the support frame 7, a first water pump 12 connected to one side of the water tank 11 by a pipe, a connecting pipe 13 connected to one side of the first water pump 12 by a flange, a conveying pipe 14 fixedly installed on the surface of the connecting pipe 13, and a nozzle 15 fixedly installed at one end of the conveying pipe 14.
[0021] Furthermore, the magnetic roller 2 is driven to rotate by a motor, the hopper 5 is located directly below the magnetic roller 2, and the scraper 6 is in contact with the surface of the conveyor belt 3. Through the setting of the magnetic roller 2, the magnetic roller 2 has a high magnetic field strength, which can effectively adsorb steel materials. When the conveyor belt 3 transports steel and impurities, the magnetic roller 2 generates magnetism to adsorb the steel onto the surface of the conveyor belt 3, making it easy to be scraped off by the scraper 6.
[0022] Furthermore, the upper part of the cylinder 8 is fixedly connected to the lower end of the hopper 5, and a discharge opening is provided on one side of the cylinder 8. With the setting of the cylinder 8, the cylinder 8 can be connected to the hopper 5 and the nozzle 15 respectively during use. When the material falls into the cylinder 8, the drive motor 9 can drive the spiral blade 10 to rotate to transport the material. The nozzle 15 can spray water to clean the steel.
[0023] Furthermore, the conveying pipes 14 are evenly distributed on the surface of the connecting pipes 13, and one end of the nozzles 15 is fixedly connected to the cylinder 8. Through the setting of the nozzles 15, multiple sets of nozzles 15 can spray at the same time, which can clean the steel more thoroughly.
[0024] Furthermore, a vibrating screen 16 is fixedly installed on one side of the bottom of the fixed frame 1. A precision filter screen 17 is fixedly installed on one end of the vibrating screen 16. A second water pump 18 is connected to one end of the vibrating screen 16 via a surface pipe. A filter cylinder 19 is connected to one side of the second water pump 18 via a side pipe. Through the setting of the vibrating screen 16, steel is driven by the spiral blades 10 and falls into the vibrating screen 16 from one side opening of the cylinder 8. Then the vibrating screen 16 vibrates, causing the steel on the precision filter screen 17 to move during the vibration. At the same time, the cleaning water can flow through the precision filter screen 17 from the inside of the vibrating screen 16.
[0025] Furthermore, the position of the vibrating screen 16 corresponds to the position of the opening on one side of the cylinder 8. The pipe connecting the cylinder 8 and the second water pump 18 is made of flexible hose. Through the setting of the second water pump 18, the second water pump 18 can recycle the water used to clean the steel, and then filter it through the filter cartridge 19 before sending it back to the water tank 11 for recycling.
[0026] Furthermore, the filter cartridge 19 is provided with multiple layers of filter screens inside, and one side of the filter cartridge 19 is opened to be connected to the water tank 11 pipe. Through the filter cartridge 19, the multiple layers of filter screens inside the filter cartridge 19 can effectively remove solid impurities.
[0027] Working principle: First, the steel impurities to be processed are spread evenly on the surface of the conveyor belt 3 for conveying. When passing the magnetic roller 2 at one end, the magnetic roller 2 generates magnetic force to attract the steel to the surface of the conveyor belt 3. Then, impurities without magnetic force fall from one end of the conveyor belt 3 onto the surface of the receiving plate 4. The attracted steel adheres to the surface of the conveyor belt 3. When rotating directly under the magnetic roller 2, the scraper 6 adheres to the surface of the conveyor belt 3 and scrapes off the steel. Then, it is fed into the cylinder 8 through the hopper 5. Then, the first water pump 12 pumps water from the water tank 11 through the connecting pipe 13, the conveying pipe 14 and the nozzle 15 to spray water onto the inside of the cylinder 8. The drive motor 9 drives the spiral blades 10 to rotate, moving the steel and ensuring it comes into full contact with the cleaning water to remove impurities from the steel surface. Then, the steel and cleaning water flow from the opening at one end of the cylinder 8 into the vibrating screen 16 below. The vibrating screen 16 drives the precision filter 17 to vibrate, shaking the steel. At the same time, the cleaning water flows through the precision filter 17 from the bottom. Then, driven by the second water pump 18, the cleaning water is transported to the filter cylinder 19 for filtration and then returned to the water tank 11. The processed steel is discharged from the opening on one side of the vibrating screen 16.
