Description

Technical Field

[0001] This utility model belongs to the technical field of iron removal equipment, and more specifically, it relates to a real-time iron removal equipment for solid waste-based cementitious materials. Background Technology

[0002] Solid waste-based cementitious materials are a new type of environmentally friendly material with cementing properties, made primarily from industrial solid waste through physical, chemical, or thermal treatment processes. However, during the production process, due to the complex source of raw materials, iron impurities are often mixed into solid waste-based cementitious materials. These impurities not only affect the physicochemical properties of the material but may also damage subsequent production processes and equipment. Therefore, iron removal equipment is usually required to remove iron impurities in the production process of solid waste-based cementitious materials.

[0003] According to application number CN200820069194.0, a dry magnetic separator for tailings belongs to the category of magnetic separators for dry beneficiation of iron ore powder. The magnetic separator includes a frame, a magnetic drum conveyor, a belt separator, a belt conveyor, and a controller. The magnetic drum conveyor, belt separator, and belt conveyor are mounted on the frame. The belt conveyor is located below the magnetic drum conveyor and belt separator, and a feed hopper is located above the magnetic drum conveyor. The magnetic drum conveyor has a dual-material outlet at its output end, and both the belt separator and the belt conveyor have discharge ports at their output ends. Advantages: This equipment solves the environmental pollution problem caused by wet separation in tailings treatment. It does not use water, so there is no wastewater discharge. It can carry out open-air magnetic separation on-site, saving a lot of transportation costs. It can obtain 3%-10% iron ore powder with a grade of 30%-50% from waste tailings, turning waste into treasure. In the freezing winter of northern my country, this equipment can be used all year round, which will bring very significant economic benefits.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a magnetic separation mechanism to remove ferrous impurities from solid waste-based cementitious materials. Upon activation of the high-frequency vibration motor, the motor drives the feeding belt to vibrate via a vibrating plate, thereby agitating the solid waste-based cementitious material on the upper surface of the feeding belt. This allows the permanent magnet to more easily separate the ferrous material, improving the removal efficiency of ferrous impurities and enhancing production quality. The detection mechanism monitors the magnetic force of the permanent magnet. When the magnet's magnetic force is sufficient, it attracts a metal block, which, under the influence of the attraction force, causes the pressing rod to slide forward. Conversely, when the magnet's magnetic force decreases, its attraction... When the force applied cannot overcome the tension of the detection spring, the metal block will slide backward under the action of the detection spring. The sliding of the metal block will cause the pressing rod to trigger the pressing switch. At this time, the alarm will be powered on and sound an alarm, promptly reminding the staff to carry out maintenance. This avoids the situation where iron impurities in solid waste-based cementitious materials are not cleaned properly before being put into production, thus improving both production quality and work efficiency. Through the above-mentioned mechanism, not only is the efficient removal of iron impurities in solid waste-based cementitious materials achieved, improving production quality, but the detection of the magnetic force of permanent magnets is also realized, further ensuring production quality and improving work efficiency.

The feeding motor 7 is fixedly installed on the outside of the feeding frame 1, and the rotating shaft of the feeding motor 7 is fixedly connected to the feeding roller 5; there are two magnetic separation rollers 8, and both magnetic separation rollers 8 are rotatably connected to the inside of the magnetic separation frame 4; there are two support rollers 9, and both support rollers 9 are rotatably connected to the inside of the magnetic separation frame 4; the permanent magnet 10 is fixedly installed on the inside of the magnetic separation frame 4; the magnetic separation motor 11 is fixedly installed on the outside of the magnetic separation frame 4, and the rotating shaft of the magnetic separation motor 11 is fixedly connected to the magnetic separation roller 8; the magnetic separation mechanism is located at the upper end of the feeding frame 1.

[0027] The magnetic separation mechanism includes: a connecting chute 101, a fixing plate 102, a magnetic separation belt 12, a fixing partition 1201, a vibrating plate 13, a high-frequency vibration motor 14, a protective baffle 15, a connecting slider 1501, a support column 16, and a compression spring 17. Two sets of connecting chute 101 are provided, both sets being located inside the feeding frame 1. Two sets of fixing plates 102 are provided, both sets being fixedly connected to the outside of the feeding frame 1. The magnetic separation belt 12 covers the outside of the magnetic separation roller 8 and the support roller 9. Multiple fixing partitions 1201 are provided, all fixedly connected to the outside of the magnetic separation belt 12. The vibrating plate 13 is slidably connected to the inside of the feeding frame 1. The high-frequency vibration motor... Two high-frequency vibration motors 14 are provided, and both are fixedly installed on the lower end face of the vibration plate 13. Two protective baffles 15 are provided, and both are slidably connected to the inner side of the feeding rack 1. Two sets of connecting sliders 1501 are provided, and the two sets of connecting sliders 1501 are respectively fixedly connected to the outer side of the two protective baffles 15, and the connecting sliders 1501 are slidably connected to the connecting grooves 101.

[0028] The specific usage and function of this embodiment are as follows: When the feeding motor 7 starts, it drives the feeding belt 6 through the feeding roller 5 to feed the solid waste-based cementitious material. During the feeding process, the permanent magnet 10 adsorbs the iron material in the solid waste-based cementitious material, causing the iron material to adhere to the lower end face of the magnetic separation belt 12. When the magnetic separation motor 11 starts, it drives the magnetic separation belt 12 and the fixed partition 1201 through the magnetic separation roller 8. The movement of the fixed partition 1201 drives the magnetic separation belt. The iron material on the lower end face of the 12 gradually moves away from the permanent magnet 10. As the iron material moves away from the permanent magnet 10, the attraction force exerted by the permanent magnet 10 on the iron material decreases, and the iron material will fall off, thus achieving the screening of iron material in the solid waste-based cementitious material. When the high-frequency vibration motor 14 is started, the high-frequency vibration motor 14 will drive the feeding belt 6 to vibrate through the vibration plate 13. The vibration of the feeding belt 6 will agitate the solid waste-based cementitious material on the upper end face of the feeding belt 6, making it easier for the permanent magnet 10 to separate the iron material in the solid waste-based cementitious material.

[0030] Based on Example 1, such as Figure 1 , Figures 5-6As shown, the detection mechanism includes: a mounting plate 401, an alarm 402, a fixing rod 18, a detection box 19, a sliding plate 20, a detection spring 2001, a pressing rod 2002, a metal block 21, and a pressing switch 22; the detection mechanism is located inside the magnetic separator 4; the mounting plate 401 is fixedly connected to the outside of the magnetic separator 4; the alarm 402 is fixedly installed on the upper surface of the mounting plate 401; the fixing rod 18 is fixedly connected to the inside of the magnetic separator 4; and the detection box 19 is fixedly connected to the fixing rod.

[0031] The specific usage and function of this embodiment are as follows: When the magnetic force of the permanent magnet 10 is sufficient, the permanent magnet 10 will attract the metal block 21. The metal block 21 will be attracted and drive the pressing rod 2002 to slide forward. When the magnetic force of the permanent magnet 10 decreases, the attraction force of the permanent magnet 10 is difficult to resist the pulling force of the detection spring 2001. The metal block 21 will slide backward under the action of the detection spring 2001. The sliding of the metal block 21 will trigger the pressing switch 22 of the pressing rod 2002.
