Description

Technical Field

[0001] The utility model relates to the field of coal purification, in particular to a weakly sticky coal magnetic separation device. Background Art

[0002] Weakly sticky coal is coal with a low or medium degree of coalification, and is often used as a gasification raw material and power fuel. Weakly sticky coal is mixed with a lot of metal impurities when it is mined. If the metal impurities are not removed, it is easy to cause excessive metal ion content when refining coal tar, causing catalyst deactivation, corrosion of equipment, etc. When the coal is burned, it is easy to cause incomplete combustion and produce a large amount of carbon monoxide and sulfur dioxide. In order to improve the purity of coal, it is necessary to adsorb the metal impurities mixed in it.

[0003] The current adsorption method is inefficient and can easily lead to low purity of weakly sticky coal, which affects its use. In the current adsorption method, weakly sticky coal is adsorbed only once by magnetic attraction, which makes the adsorption incomplete and makes it difficult to fully meet the purity requirements of weakly sticky coal; the metal impurities adsorbed by the scraper in one direction are easily not scraped away cleanly, which affects the next adsorption. Utility Model Content

[0004] Aiming at the problem that the purity of weakly sticky coal is insufficient due to incomplete adsorption, the utility model provides a weakly sticky coal magnetic separation device capable of improving the purity of the weakly sticky coal.

[0005] The technical solution of the utility model is: a weakly sticky coal magnetic separation equipment, including a base, a servo motor, a lever, a connecting strip, a magnetic plate, a small spring, a slider, a scraping strip, a reset spring, a transmission assembly and a rotating rod. The base is fixedly connected with a servo motor, the output shaft of the servo motor is fixedly connected with a rotating rod, the rotating rod is fixedly connected with a lever, both ends of the lever are slidably connected with connecting strips, the lower end of each connecting strip is rotatably connected with a magnetic plate, each magnetic plate is fixedly connected with a small spring, the other end of each small spring is fixedly connected to the connecting strip, both sides of each magnetic plate are slidably connected with sliders, the bottom of each slider is fixedly connected with a reset spring, the other end of each reset spring is fixedly connected with a scraping strip, each scraping strip is slidably connected to two adjacent sliders, each magnetic plate has only one scraping strip at the bottom that is slidably connected to it, and the transmission assembly is fixedly connected to the base.

[0006] As a further preferred solution, square grooves are provided on both sides of the lever, and connecting strips are slidably connected in the square grooves.

[0007] As a further preferred solution, it also includes corrugated rails and sliding plates. Two corrugated rails are fixedly connected to the bottom of each magnetic plate, and a sliding plate is slidably connected to each scraping strip, and the sliding plate is in contact with the corrugated rails.

[0008] As a further preferred solution, grooves are provided on both sides of each magnetic attraction plate, and the grooves are slidably connected to the slider.

[0009] As a further preferred solution, it also includes baffles, two baffles are fixedly connected to the base, and the two baffles are located on both sides of the conveyor belt.

[0010] The utility model has the following advantages: 1. The utility model drives two magnetic suction plates to move up and down alternately through a lever, which can adsorb the weakly sticky coal on the conveyor belt twice, and can adsorb the metal impurities in the weakly sticky coal more cleanly, making the purity of the weakly sticky coal higher.

[0011] 2.

[0018] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0019] Embodiment 1: A weakly sticky coal magnetic separation device, such as Figure 1-Figure 5As shown, it includes a base 1, a servo motor 2, a lever 3, a connecting bar 4, a magnetic plate 5, a small spring 51, a slider 6, a scraping bar 7, a reset spring 8, a transmission component 9, a rotating rod 10 and a baffle 15. The base 1 is connected to the servo motor 2 by bolts, the output shaft of the servo motor 2 is connected to the rotating rod 10 by a coupling, the rotating rod 10 is connected to the lever 3 by a coupling, both ends of the lever 3 are slidably connected to the connecting bar 4, the lower end of each connecting bar 4 is rotatably connected to the magnetic plate 5, each magnetic plate 5 is connected to a small spring 51 by a hook, and the small spring 51 is used to reset the magnetic plate 5. The other end of each small spring 51 is connected to the connecting bar 4 through a hook, and sliders 6 are slidably connected to both sides of each magnetic plate 5. A reset spring 8 is connected to the bottom of each slider 6 through a hook. The other end of each reset spring 8 is connected to a scraping bar 7 through a hook. The reset spring 8 is used to drive the scraping bar 7 to move. Each scraping bar 7 is slidably connected to two adjacent sliders 6. There is only one scraping bar 7 slidably connected to the bottom of each magnetic plate 5. The conveying assembly 9 is connected to the base 1 by bolts, and two baffles 15 are connected to the base 1 by bolts. The two baffles 15 are located on both sides of the conveyor belt.

[0020] Working principle: the staff starts the servo motor 2 and the conveying component 9 at the same time. The conveying component 9 can convey the coal. The baffles 15 on both sides of the conveyor belt can prevent the coal from falling out of the conveying component 9. The reciprocating rotation of the output shaft of the servo motor 2 will drive the rotating rod 10 to rotate reciprocatingly. The reciprocating rotation of the rotating rod 10 will drive the lever 3 to swing back and forth. The reciprocating swing of the lever 3 will drive the connecting bars 4 at both ends to move up and down alternately. The two connecting bars 4 will slide on the lever 3. The up and down reciprocating movement of the two connecting bars 4 will drive the magnetic suction plate 5 to move up and down alternately.

[0021] One of the magnetic plates 5 will rise and contact with the base 1. The end of the magnetic plate 5 away from the conveyor belt will be pressed by the base 1 and tilted. The tilt of the magnetic plate 5 will compress the small spring 51. Under the action of gravity, the slider 6 will move in the groove toward the motor. The movement of the slider 6 toward the motor will stretch the reset spring 8, so that the scraping bar 7 will be close to the lower side of the magnetic plate 5 and move toward the motor. The scraping bar 7 can scrape off the metal impurities adsorbed on the magnetic plate 5. Under the action of the lever, the other magnetic suction plate 5 will drop, and the drop of the magnetic suction plate 5 will drive the small spring 51 to reset, and the reset of the small spring 51 will keep the magnetic suction plate 5 in a horizontal state. Under the action of gravity, the sliders 6 on the left and right sides of the magnetic suction plate 5 will move along the groove in the direction away from the motor, and the movement of the slider 6 in the direction away from the motor will drive the reset spring 8 to move in the direction away from the motor. The movement of the reset spring 8 in the direction away from the motor will drive the scraper bar 7 to move in the direction away from the motor, and the movement of the reset spring 8 will reset it. The reset of the reset spring 8 will make the scraper bar 7 always contact with the bottom of the magnetic suction plate 5, and the slider 6 and the scraper bar 7 move to the end of the magnetic suction plate 5 away from the motor, so that the magnetic suction plate 5 can absorb the metal impurities in the weakly sticky coal on the conveyor belt. The two magnetic suction plates 5 perform reciprocating up and down alternately in this way, and can adsorb the weakly sticky coal on the conveyor belt twice, so that the metal impurities in the weakly sticky coal can be adsorbed more cleanly, and the purity of the weakly sticky coal can be higher.

[0022] Embodiment 2: Based on embodiment 1, Figure 1-Figure 5 As shown, it also includes corrugated slide rails 13 and slide plates 14 . Two corrugated slide rails 13 are connected to the bottom of each magnetic attraction plate 5 by bolts. A slide plate 14 is slidably connected to each scraping strip 7 , and the slide plate 14 is in contact with the corrugated slide rails 13 .

[0023] The reciprocating movement of the scraping bar 7 drives the sliding plate 14 to move reciprocatingly, and the sliding plate 14 moves along the corrugated slide rail 13 at the same time, so that the sliding plate moves left and right while moving forward and backward, and can cooperate with the scraping bar to scrape off the metal impurities adsorbed on the magnetic plate with greater force.

[0024] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
