[0003] There is also a patent in the prior art regarding a technical solution for a high-efficiency desulfurization activated carbon preparation system. For example, a Chinese patent with application number CN2019220305087 discloses a coal belt conveyor, including a counterweight frame and a belt conveyor, wherein the counterweight frame includes an isosceles trapezoidal frame base, a rectangular frame base, an inverted U-shaped bracket and a hollow bracket, wherein the rectangular frame base and the bottom of the isosceles trapezoidal frame base are both provided with self-locking universal wheels, and support legs are screwed on four protrusions symmetrically arranged front and back of the rectangular frame base and on the connecting plate on the inner side of the isosceles trapezoidal frame base, and the top of the rear end of the hollow bracket is rotatably connected to the frame of the belt conveyor through two first pins symmetrically arranged front and back, and a longitudinal support plate is fixedly provided at the inner bottom end of the inverted U-shaped bracket, and an upper support platform on an electric scissor lift platform fixedly provided on the top of the longitudinal support plate is rotatably connected to the frame of the belt conveyor through two second pins symmetrically arranged front and back;

[0004] The above-mentioned prior art arranges an isosceles trapezoidal frame base, a rectangular frame base, an inverted U-shaped bracket and a hollow bracket, which makes the application easy to move and facilitates the transportation and loading of coal, and can effectively reduce labor and improve transportation efficiency. However, when the belt conveyor in the above-mentioned prior art transports the activated carbon raw material, it is unable to process the iron filings in the coal powder, so that when the activated carbon raw material is subsequently subjected to the powder making process, the iron filings in the activated carbon raw material will affect the powder making efficiency of the powder making machine, and even cause damage to the powder making machine, resulting in poor quality of the activated carbon raw material.

[0005] In view of this, the present invention proposes a high-efficiency desulfurization activated carbon preparation system to solve the above problems. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art and solve the problem that the belt conveyor in the prior art is unable to process the iron filings in the coal powder when transporting the activated carbon raw material, so that when the activated carbon raw material is subsequently subjected to the powder making process, the iron filings in the activated carbon raw material will affect the powder making efficiency of the powder making machine, and even cause damage to the powder making machine, resulting in poor quality of the activated carbon raw material; the present invention proposes a high-efficiency desulfurization activated carbon preparation system.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a high-efficiency desulfurization activated carbon preparation system, which preparation system includes a coal preparation process, a powder making process, a molding process, a carbonization process, an activation process and a cooling and packaging process; the coal preparation process uses a belt conveyor to transport the activated carbon raw material, the powder making process is used to grind and powder the activated carbon raw material, the molding process is used to mold the activated carbon raw material, the carbonization process is used to carbonize and incinerate the activated carbon raw material, the activation process is used to generate activated material from the activated carbon raw material, and the cooling and packaging process is used to cool and package the activated carbon raw material; the coal preparation process includes a belt conveyor, and the belt conveyor includes a bracket, a conveyor belt, a motor and a collecting plate; the bracket is composed of a bracket leg and a bracket plate, the bracket leg on the left side is longer than the bracket leg on the right side, the bracket plate is fixedly connected to the upper end of the bracket leg, the bracket leg is inclined, and the upper inner wall of the bracket plate is opened A No. 1 slot is provided, in which a conductive copper sheet is fixedly connected; the front and rear sides of the electromagnet are rotatably connected with a rotating shaft, the rotating shaft is located at the diagonal of the conductive column, the outer ring of the rotating shaft is fixedly connected to a No. 1 rod, and when the No. 1 rod rotates, the No. 1 rod does not contact the conductive column; the conveyor belt is rotatably connected to the inner wall of the bracket plate through an axle wheel, the conveyor belt is tilted, and electromagnets are evenly arranged on the surface of the conveyor belt, the electromagnets are in the shape of a right-angled trapezoid, and conductive columns are evenly arranged on the electromagnets close to the bracket plate, and the sides of the conductive columns are wrapped with an insulating layer, the conductive columns are located at the top angle of the electromagnet away from the conveyor belt, one end of the conductive column is slidably connected to the No. 1 slot and the conductive column contacts the conductive copper sheet; the motor is fixedly connected to one side of the bracket plate, and the output shaft of the motor passes through the bracket plate and is rotatably connected to the axle wheel on the right side of the conveyor belt; the collecting plate is fixedly connected to the bracket leg, the collecting plate is located below the conveyor belt, and the collecting plate is parallel to the horizontal plane;

[0008] When in use, when desulfurized activated carbon is prepared, the activated carbon raw material is first transported through the coal preparation process. The activated carbon raw material includes coking coal and coke powder. During preparation, the coking coal and coke powder are transported to the coal preparation bin by using a belt conveyor; by opening a No. 1 groove on the bracket plate, making the No. 1 groove parallel to the bracket plate, and setting a conductive copper sheet in the No. 1 groove, and connecting the conveyor belt by rotating the inner wall of the bracket plate. When the motor rotates, the motor drives the conveyor belt to rotate, and the conveyor belt transports the activated carbon raw material, and by arranging electromagnets on the surface of the conveyor belt, making the electromagnets in a right-angle trapezoidal arrangement, and the electromagnets are connected to each other by iron sheets, and the iron sheets are located inside the conveyor belt, so that the iron sheets do not affect the coal powder transportation on the conveyor belt. Working, by setting conductive columns on both sides of the electromagnet close to the bracket plate, and making one end of the conductive column extend into the No. 1 slot and contact the conductive copper sheet, by energizing the conductive copper sheet, when the motor rotates, the conveyor belt rotates, and the conveyor belt transports the activated carbon raw material. As the conveyor belt rotates, the conductive column enters the No. 1 slot and one end of the conductive column contacts the conductive copper sheet. The current in the conductive copper sheet enters the electromagnet through the conductive column, and the electromagnet generates magnetism. When the conductive column enters the No. 1 slot, since the side of the conductive column is wrapped with an insulating layer, the problem of electric shock to personnel caused by the exposed conductive column is avoided. Moreover, the conductive copper sheet is located inside the No. 1 slot, and it is not easy for construction personnel to touch it, which further avoids construction. Electric shock occurs to personnel. When the activated carbon raw materials are transported, the electromagnet generates magnetism to absorb the iron filings in the activated carbon raw materials. When the activated carbon raw materials leave the conveyor belt and enter the coal preparation bin, the iron filings are absorbed on the electromagnet, thereby reducing the iron filings content in the activated carbon raw materials during the subsequent preparation of the activated carbon. When the electromagnet moves with the conveyor belt, when the electromagnet moves to the lower surface of the conveyor belt, the conductive column on the electromagnet detaches from the No. 1 slot, the electromagnet is demagnetized, and the iron filings absorbed on the electromagnet fall off the electromagnet due to its own gravity. A rotating shaft is connected to the front and rear sides of the electromagnet, and the rotating shaft is located at the diagonal of the conductive column. The No. 1 rod is fixed to the outer ring of the rotating shaft. When the motor rotates, the conveyor belt moves along The motor rotates, and the electromagnet moves with it. When the electromagnet is located on the upper surface of the conveyor belt, rod No. 1 is rotatably connected to the conveyor belt, so that the contact area between the electromagnet and the activated carbon is increased, thereby improving the electromagnet's adsorption efficiency for iron filings. When the electromagnet moves to the bottom of the conveyor belt with the conveyor belt, rod No. 1 rotates around the rotating shaft due to its own gravity, and then rod No. 1 remains perpendicular to the horizontal plane. During the rotation of rod No. 1, rod No. 1 scrapes the front and rear sides of the electromagnet to scrape off the iron filings on the front and rear sides of the electromagnet, thereby improving the subsequent adsorption efficiency of the electromagnet for iron filings; thereby improving the adsorption efficiency of the electromagnet, and preventing the iron filings in the activated carbon raw materials from affecting subsequent processes.

[0009] Preferably, the interior of the conveyor belt is hollow, the inner wall of the bracket plate is rotatably connected to a rotating unit through a No. 1 column, and the rotating unit is located inside the conveyor belt, and the rotating unit includes a transmission rod, a swing rod and a No. 1 block; the transmission rod is located at the center of two shaft wheels of the conveyor belt, one end of the transmission rod is fixedly connected to the No. 1 column, and the transmission rod is parallel to the bracket plate, the swing rod is symmetrically arranged on the outer ring of the No. 1 column with the transmission rod as the center, and the swing rod is fixedly connected to the outer ring of the No. 1 column; the No. 1 block is fixedly connected to the end of the swing rod away from the No. 1 column, and the No. 1 block contacts the inner wall of the conveyor belt, and an annular groove is provided on the outer ring of the shaft wheel on the right side of the conveyor belt, and the annular groove is located in the middle of the left and right ends of the shaft wheel, and a convex block is fixedly connected in the annular groove, and the convex block is fixedly connected to the inner wall of the annular groove, and one end of the transmission rod extends into the annular groove and is pressed against the convex block;

[0010] When in use, when the motor rotates, an annular groove is opened on the shaft wheel on the right side of the conveyor belt, so that the annular groove is located in the middle of the front and rear ends of the shaft wheel on the right side of the conveyor belt, and the rotating unit is rotatably connected to the inner wall of the bracket plate through the No. 1 column, and the transmission rod and the swing rod are respectively fixed on the No. 1 column. When the motor rotates, the protrusion rotates in the annular groove. Since one end of the transmission rod extends into the annular groove, when the protrusion rotates with the shaft wheel, the protrusion squeezes the transmission rod, and the transmission rod is fixed to the No. 1 column. The No. 1 column is rotatably connected to the inner wall of the bracket plate. The protrusion squeezes the transmission rod, causing the No. 1 column to rotate. When the transmission rod rotates When the cam passes through the transmission rod, the gravity of the swing rod and block No. 1 is greater than that of the transmission rod, and block No. 1 and the swing rod naturally sink due to gravity, and block No. 1 hits the bottom of the conveyor belt, further causing the iron filings on the electromagnet to fall off, thereby improving the adsorption efficiency of the electromagnet.

[0011] Preferably, each of the first blocks has a rectangular groove on its end surface close to the conveyor belt, a second column is rotatably connected in the rectangular groove, and the outer ring of the second column contacts the inner wall of the conveyor belt;

[0012] When in use, a rectangular groove is opened on the end face of one end of block No. 1 close to the conveyor belt, and the No. 2 column is rotated in the rectangular groove to connect, and the outer ring of the No. 2 column is in contact with the conveyor belt. When the motor rotates, the conveyor belt rotates, and the inner wall of the conveyor belt contacts with block No. 1. The No. 2 column is rotated in the rectangular groove to connect, and when the conveyor belt slides on the surface of block No. 1, the No. 2 column contacts with the conveyor belt, and the No. 2 column rotates, so that the friction between the conveyor belt and block No. 1 is reduced, thereby reducing the friction damage caused by the conveyor belt and block No. 1, thereby improving the use efficiency of the conveyor belt and block No. 1, and further improving the working efficiency of the belt conveyor.

[0013] Preferably, a brush is fixedly connected to one end of the collecting plate close to the middle of the conveyor belt, and the brush extends upward and contacts the lower end surface of the conveyor belt;

[0014] When in use, a brush is fixedly connected to one end of the collecting plate close to the middle of the conveyor belt, and the brush is extended upward and contacts the lower end surface of the conveyor belt. The motor rotates, the conveyor belt rotates with the motor, and the electromagnet rotates with the conveyor belt. When the electromagnet moves to the lower end surface of the conveyor belt, the conductive column on the electromagnet detaches from the No. 1 slot, the electromagnet is demagnetized, and the iron filings adsorbed on the electromagnet are affected by their own gravity and fall off the electromagnet onto the collecting plate, thereby improving the subsequent adsorption efficiency of the electromagnet; and when the swing rod hits the conveyor belt, the lower side of the conveyor belt vibrates, and the electromagnet vibrates with the conveyor belt, thereby further improving the detachment efficiency of the iron filings above the electromagnet, and then improving the adsorption efficiency of the electromagnet for the iron filings.

[0015] Preferably, the brush is arranged obliquely on the collecting plate, the upper end of the brush is located on the left side of the lower end of the brush, and a magnet sheet is arranged on the upper surface of the collecting plate;

[0016] When in use, when the motor rotates, the conveyor belt rotates, and the electromagnet moves with the conveyor belt. When the electromagnet moves to the bottom of the conveyor belt, the conductive column detaches from the No. 1 slot, the electromagnet is demagnetized, and the iron filings on the electromagnet fall off from above the electromagnet. The iron filings are adsorbed by the magnet sheet above the collecting plate below. When the iron filings fall on the magnet sheet, it is difficult for the iron filings to roll out of the collecting plate, thereby avoiding the iron filings from scattering. By tilting the brush above the collecting plate, when the electromagnet contacts the brush, the brush is tilted, the resistance of the brush to the electromagnet is increased, and the contact between the brush and the electromagnet is closer, so that the brush can clean the electromagnet more fully, thereby improving the subsequent adsorption efficiency of the electromagnet.

[0017] Preferably, the end of the No. 1 rod away from the conveyor belt is arranged in an arc shape, and the side of the No. 1 rod close to the electromagnet is slidably fitted with the electromagnet;

[0018] When in use, the end of rod No. 1 away from the conveyor belt is set in an arc shape. When the motor rotates, the conveyor belt rotates, and the electromagnet rotates with the conveyor belt. When the electromagnet moves to the bottom of the conveyor belt, rod No. 1 is acted upon by its own gravity and rotates around the rotating shaft. When rod No. 1 rotates, rod No. 1 scrapes the front and rear sides of the electromagnet to scrape off iron filings on the front and rear sides of the electromagnet. When the end of rod No. 1 away from the conveyor belt is set in an arc shape, the scraping efficiency of the edges of rod No. 1 on the electromagnet is improved, and when rod No. 1 passes through the brush, the destructive effect of the arc-shaped rod No. 1 on the brush is reduced, thereby improving the use efficiency of the belt conveyor.

[0019] The beneficial effects of the present invention are as follows:

The present invention discloses a high-efficiency desulfurization activated carbon preparation system, which comprises a No. 1 slot, a conductive copper sheet, a conveyor belt, an electromagnet and a conductive column; a motor drives the conveyor belt to rotate, the conductive column enters the No. 1 slot and the No. 1 column contacts the conductive copper sheet, and the electromagnet generates magnetism to adsorb iron filings in the activated carbon raw material. When the electromagnet moves to the lower surface of the conveyor belt along with the conveyor belt, the conductive column on the electromagnet separates from the No. 1 slot, the electromagnet is demagnetized, and the iron filings adsorbed on the electromagnet fall off the electromagnet due to their own gravity, thereby improving the adsorption efficiency of the electromagnet and preventing the iron filings in the activated carbon raw material from affecting subsequent processes.

The present invention discloses a high-efficiency desulfurization activated carbon preparation system, which comprises a rotating shaft, a rod No. 1 and an electromagnet; the electromagnet moves with the electromagnet, and when the electromagnet is located on the upper surface of the conveyor belt, the contact area between the electromagnet and the activated carbon increases, and when the electromagnet moves to the bottom of the conveyor belt with the conveyor belt, the rod No. 1 rotates around the rotating shaft due to its own gravity, and then the rod No. 1 remains vertical to the horizontal. During the rotation of the rod No. 1, the rod No. 1 scrapes the front and rear sides of the electromagnet to scrape off the iron filings on the front and rear sides of the electromagnet, thereby improving the subsequent adsorption efficiency of the electromagnet on the iron filings.

The front and rear sides of the magnet 13 are rotatably connected with a rotating shaft, and the rotating shaft is located at the diagonal of the conductive column 14. The outer ring of the rotating shaft is fixedly connected to a rod 16, and when the rod 16 rotates, the rod 16 does not contact the conductive column 14; the conveyor belt 11 is rotatably connected to the inner wall of the bracket plate 112 through an axle wheel, and the conveyor belt 11 is tilted. The surface of the conveyor belt 11 is evenly provided with electromagnets 13, and the electromagnets 13 are in the shape of a right-angled trapezoid. The electromagnets 13 close to the bracket plate 112 are evenly provided with conductive columns 14. The conductive column 14 is wrapped with an insulating layer on its side, and is located at a top corner of the electromagnet 13 away from the conveyor belt 11. One end of the conductive column 14 is slidably connected to the No. 1 slot 113, and the conductive column 14 is in contact with the conductive copper sheet. The motor is fixedly connected to one side of the bracket plate 112, and the output shaft of the motor passes through the bracket plate 112 and is rotatably connected to the shaft wheel on the right side of the conveyor belt 11. The collecting plate 12 is fixedly connected to the bracket leg 111, and is located below the conveyor belt 11, and is parallel to the horizontal plane.

[0030] When in use, when the desulfurized activated carbon is prepared, the activated carbon raw material is first transported through the coal preparation process. The activated carbon raw material includes coking coal and coke powder. During preparation, the coking coal and coke powder are transported to the coal preparation bin by using a belt conveyor; a No. 1 groove 113 is opened on the bracket plate 112, so that the No. 1 groove 113 is parallel to the bracket plate 112, and a conductive copper sheet is arranged in the No. 1 groove 113. The conveyor belt 11 is connected to the inner wall of the bracket plate 112 by rotating. When the motor rotates, the motor drives the conveyor belt 11 to rotate, and the conveyor belt 11 conveys the activated carbon raw material. The conveyor belt 11 is provided with an electromagnet 13 on its surface, so that the electromagnet 13 is arranged in a right-angle trapezoidal shape, and the electromagnets 13 are connected to each other through iron sheets, and the iron sheets are located inside the conveyor belt 11, so that the iron sheets do not affect the coal powder conveying work on the conveyor belt 11, and conductive columns 14 are arranged on both sides of the electromagnet 13 close to the bracket plate 112, and one end of the conductive column 14 is extended into the first groove 113 to contact the conductive copper sheet, and the conductive copper sheet is energized. When the motor rotates, the conveyor belt 11 rotates, and the conveyor belt 11 conveys the activated carbon raw material. During transportation, as the conveyor belt 11 rotates, the conductive column 14 enters the first slot 113 and one end of the conductive column 14 contacts the conductive copper sheet. The current in the conductive copper sheet enters the electromagnet 13 through the conductive column 14, and the electromagnet 13 generates magnetism. When the conductive column 14 enters the first slot 113, the side of the conductive column 14 is wrapped with an insulating layer, which avoids the problem of electric shock caused by the exposed conductive column 14. The conductive copper sheet is located inside the first slot 113 and is not easy to be touched by construction workers, which further avoids electric shock to construction workers. When the material is being transported, the electromagnet 13 generates magnetism to adsorb the iron filings in the activated carbon raw material. When the activated carbon raw material leaves the conveyor belt 11 and enters the coal preparation bin, the iron filings are adsorbed on the electromagnet 13, thereby reducing the iron filings content in the activated carbon raw material during subsequent preparation of the activated carbon. When the electromagnet 13 moves along with the conveyor belt 11, when the electromagnet 13 moves to the lower surface of the conveyor belt 11, the conductive column 14 on the electromagnet 13 is separated from the No. 1 slot 113, the electromagnet 13 is demagnetized, and the iron filings adsorbed on the electromagnet 13 fall off from the electromagnet 13 due to its own gravity.A rotating shaft is rotatably connected to the front and rear sides of the electromagnet 13, and the rotating shaft is located at the diagonal of the conductive column 14. A rod 16 is fixed to the outer ring of the rotating shaft. When the motor rotates, the conveyor belt 11 rotates with the motor, and the electromagnet 13 moves with the electromagnet 13. When the electromagnet 13 is located on the upper surface of the conveyor belt 11, the rod 16 is rotatably connected to the conveyor belt 11, so that the contact area between the electromagnet 13 and the activated carbon is increased, thereby improving the adsorption efficiency of the electromagnet 13 for iron filings. When the electromagnet 13 moves to the bottom of the conveyor belt 11 with the conveyor belt 11, the rod 16 rotates around the rotating shaft due to its own gravity, and then the rod 16 remains vertical to the horizontal plane. During the rotation of the rod 16, the rod 16 scrapes the front and rear sides of the electromagnet 13 to scrape off the iron filings on the front and rear sides of the electromagnet 13, thereby improving the subsequent adsorption efficiency of the electromagnet 13 for iron filings; thereby improving the adsorption efficiency of the electromagnet 13, and then avoiding the iron filings in the activated carbon raw material affecting the subsequent processes. ;

[0031] As a specific embodiment of the present invention, the interior of the conveyor belt 11 is hollow, the inner wall of the bracket plate 112 is rotatably connected to the rotating unit 2 through the No. 1 column 15, the rotating unit 2 is located inside the conveyor belt 11, and the rotating unit 2 includes a transmission rod 21, a swing rod 22 and a No. 1 block 23; the transmission rod 21 is located at the center of the two shaft wheels of the conveyor belt 11, one end of the transmission rod 21 is fixedly connected to the No. 1 column 15, and the transmission rod 21 is parallel to the bracket plate 112, and the swing rod 22 is symmetrical with the transmission rod 21 as the center. It is arranged on the outer ring of the No. 1 column 15, and the swing rod 22 is fixedly connected to the outer ring of the No. 1 column 15; the No. 1 block 23 is fixedly connected to the end of the swing rod 22 away from the No. 1 column 15, and the No. 1 block 23 contacts the inner wall of the conveyor belt 11. The outer ring of the shaft wheel on the right side of the conveyor belt 11 is provided with an annular groove 24, and the annular groove 24 is located in the middle of the left and right ends of the shaft wheel. A convex block 25 is fixedly connected in the annular groove 24, and the convex block 25 is fixedly connected to the inner wall of the annular groove 24. One end of the transmission rod 21 extends into the annular groove 24 and is pressed against the convex block 25;

[0032] When in use, when the motor rotates, an annular groove 24 is opened on the shaft wheel on the right side of the conveyor belt 11, so that the annular groove 24 is located in the middle of the front and rear ends of the shaft wheel on the right side of the conveyor belt 11, and the rotating unit 2 is rotatably connected to the inner wall of the bracket plate 112 through the No. 1 column 15, and the transmission rod 21 and the swing rod 22 are respectively fixed on the No. 1 column 15. When the motor rotates, the protrusion 25 rotates in the annular groove 24. Since one end of the transmission rod 21 extends into the annular groove 24, when the protrusion 25 rotates with the shaft wheel, the protrusion 25 squeezes the transmission rod 21, and the transmission rod 21 is fixed to the No. 1 column 15, and the No. 1 column 15 is rotatably connected to the inner wall of the bracket plate 112. The protrusion 25 squeezes the transmission rod 21, so that the No. 1 column 15 rotates. When 21 rotates, the swing rod 22 fixedly connected to the No. 1 column 15 swings, and the No. 1 block 23 of the swing rod 22 hits the conveyor belt 11, and the upper surface of the conveyor belt 11 vibrates slightly, causing the activated carbon raw material on the upper surface of the conveyor belt 11 to vibrate, and the activated carbon raw material moves downward due to the vibration. At the same time, the electromagnet 13 moves upward, so that the electromagnet 13 can adsorb the iron filings in the activated carbon raw material more fully. When the protrusion 25 passes the transmission rod 21, the gravity of the swing rod 22 and the No. 1 block 23 is greater than the transmission rod 21. The No. 1 block 23 and the swing rod 22 naturally sink due to gravity, and the No. 1 block 23 hits the bottom of the conveyor belt 11, further causing the iron filings on the electromagnet 13 to fall off, thereby improving the adsorption efficiency of the electromagnet 13.

[0033] As a specific embodiment of the present invention, each of the first blocks 23 has a rectangular groove 231 on one end surface close to the conveyor belt 11, and a second column 232 is rotatably connected in the rectangular groove 231, and the outer ring of the second column 232 contacts the inner wall of the conveyor belt 11;

[0034] When in use, a rectangular groove 231 is opened on the end face of the No. 1 block 23 close to the conveyor belt 11, and the No. 2 column 232 is rotated and connected in the rectangular groove 231, and the outer circle of the No. 2 column 232 is in contact with the conveyor belt 11. When the motor rotates, the conveyor belt 11 rotates, and the inner wall of the conveyor belt 11 contacts with the No. 1 block 23. The No. 2 column 232 is rotated and connected in the rectangular groove 231. When the conveyor belt 11 slides on the surface of the No. 1 block 23, the No. 2 column 232 contacts with the conveyor belt 11, and the No. 2 column 232 rotates, so that the friction between the conveyor belt 11 and the No. 1 block 23 is reduced, thereby reducing the friction damage caused by the conveyor belt 11 and the No. 1 block 23, thereby improving the use efficiency of the conveyor belt 11 and the No. 1 block 23, and then improving the working efficiency of the belt conveyor.

[0035] As a specific embodiment of the present invention, a brush 114 is fixedly connected to one end of the collecting plate 12 close to the middle of the conveyor belt 11, and the brush 114 extends upward, and the brush 114 contacts the lower end surface of the conveyor belt 11;

[0036] When in use, by fixing the brush 114 at one end of the collecting plate 12 close to the middle of the conveyor belt 11, and making the brush 114 extend upward and contact the lower end surface of the conveyor belt 11, the motor rotates, the conveyor belt 11 rotates with the motor, and the electromagnet 13 rotates with the conveyor belt 11. When the electromagnet 13 moves to the lower end surface of the conveyor belt 11, the conductive column 14 on the electromagnet 13 disengages from the No. 1 slot 113, and the electromagnet 13 is demagnetized. The iron filings adsorbed on the electromagnet 13 are affected by their own gravity, and the iron filings fall off the electromagnet 13 onto the collecting plate 12, thereby improving the subsequent adsorption efficiency of the electromagnet 13; and when the swing rod 22 hits the conveyor belt 11, the lower side of the conveyor belt 11 vibrates, and the electromagnet 13 vibrates with the conveyor belt 11, thereby further improving the separation efficiency of the iron filings above the electromagnet 13, and then improving the adsorption efficiency of the electromagnet 13 for the iron filings.

[0037] As a specific embodiment of the present invention, the brush 114 is tilted on the collecting plate 12, the upper end of the brush 114 is located on the left side of the lower end of the brush 114, and a magnet sheet is provided on the upper end surface of the collecting plate 12;

[0038] During use, when the motor rotates, the conveyor belt 11 rotates, and the electromagnet 13 moves with the conveyor belt 11. When the electromagnet 13 moves to the bottom of the conveyor belt 11, the conductive column 14 disengages from the No. 1 slot 113, the electromagnet 13 is demagnetized, and the iron filings on the electromagnet 13 fall off from above the electromagnet 13. The iron filings are adsorbed by the magnet sheet above the collecting plate 12 below. When the iron filings fall on the magnet sheet, it is difficult for the iron filings to roll out of the collecting plate 12, thereby avoiding the iron filings from being scattered. By tilting the brush 114 above the collecting plate 12, when the electromagnet 13 contacts the brush 114, the brush 114 is tilted, and the resistance of the brush 114 to the electromagnet 13 is increased, thereby making the brush 114 contact the electromagnet 13 more closely, so that the brush 114 can clean the electromagnet 13 more fully, thereby improving the subsequent adsorption efficiency of the electromagnet 13.

[0039] As a specific embodiment of the present invention, the end of the No. 1 rod 16 away from the conveyor belt 11 is arranged in an arc shape, and the side of the No. 1 rod 16 close to the electromagnet 13 is slidably fitted with the electromagnet 13;

[0040] When in use, by making the end of rod No. 16 away from the conveyor belt 11 in an arc shape, when the motor rotates, the conveyor belt 11 rotates, and the electromagnet 13 rotates with the conveyor belt 11. When the electromagnet 13 moves to the bottom of the conveyor belt 11, rod No. 16 is affected by its own gravity and rotates around the rotating shaft. When rod No. 16 rotates, rod No. 16 scrapes the front and rear sides of the electromagnet 13 to scrape off the iron filings on the front and rear sides of the electromagnet 13. When the end of rod No. 16 away from the conveyor belt 11 is in an arc shape, the scraping efficiency of the edges of rod No. 16 on the electromagnet 13 is improved, and when rod No. 16 passes through the brush 114, the destructive effect of the arc-shaped rod No. 16 on the brush 114 is reduced, thereby improving the use efficiency of the belt conveyor.

[0041] The specific workflow is as follows:

[0042] When desulfurized activated carbon is prepared, the activated carbon raw material is first transported through the coal preparation process. The activated carbon raw material includes coking coal and coke powder. During preparation, the coking coal and coke powder are transported to the coal preparation bin by using a belt conveyor; a No. 1 groove 113 is opened on the support plate 112, so that the No. 1 groove 113 is parallel to the support plate 112, and a conductive copper sheet is arranged in the No. 1 groove 113. The conveyor belt 11 is connected to the inner wall of the support plate 112 by rotating. When the motor rotates, the motor drives the conveyor belt 11 to rotate, and the conveyor belt 11 transports the activated carbon raw material. , by arranging the electromagnet 13 on the surface of the conveyor belt 11, so that the electromagnet 13 is arranged in a right-angle trapezoidal shape, and the electromagnets 13 are connected to each other by iron sheets, and the iron sheets are located inside the conveyor belt 11, so that the iron sheets do not affect the coal powder conveying work on the conveyor belt 11, by arranging conductive columns 14 on both sides of the electromagnet 13 close to the bracket plate 112, and one end of the conductive column 14 is extended into the first groove 113 to contact the conductive copper sheet, by energizing the conductive copper sheet, when the motor rotates, the conveyor belt 11 rotates, and the conveyor belt 11 transports the activated carbon raw material As the conveyor belt 11 rotates, the conductive column 14 enters the first slot 113 and one end of the conductive column 14 contacts the conductive copper sheet. The current in the conductive copper sheet enters the electromagnet 13 through the conductive column 14, and the electromagnet 13 generates magnetism. When the conductive column 14 enters the first slot 113, the side of the conductive column 14 is wrapped with an insulating layer, which avoids the problem of electric shock caused by the exposed conductive column 14. The conductive copper sheet is located inside the first slot 113 and is not easy to be touched by construction workers, which further avoids electric shock to construction workers. During transportation, the electromagnet 13 generates magnetism to adsorb the iron filings in the activated carbon raw material. When the activated carbon raw material leaves the conveyor belt 11 and enters the coal preparation bin, the iron filings are adsorbed on the electromagnet 13, thereby reducing the iron filings content in the activated carbon raw material during subsequent preparation of the activated carbon. When the electromagnet 13 moves along with the conveyor belt 11, when the electromagnet 13 moves to the lower surface of the conveyor belt 11, the conductive column 14 on the electromagnet 13 is separated from the No. 1 slot 113, the electromagnet 13 is demagnetized, and the iron filings adsorbed on the electromagnet 13 fall off from the electromagnet 13 due to its own gravity.A rotating shaft is rotatably connected to the front and rear sides of the electromagnet 13, and the rotating shaft is located at the diagonal of the conductive column 14. A rod 16 is fixed to the outer ring of the rotating shaft. When the motor rotates, the conveyor belt 11 rotates with the motor, and the electromagnet 13 moves with the electromagnet 13. When the electromagnet 13 is located on the upper surface of the conveyor belt 11, the rod 16 is rotatably connected to the conveyor belt 11, so that the contact area between the electromagnet 13 and the activated carbon is increased, thereby improving the adsorption efficiency of the electromagnet 13 for iron filings. When the electromagnet 13 moves to the bottom of the conveyor belt 11 with the conveyor belt 11, the rod 16 rotates around the rotating shaft due to its own gravity, and then the rod 16 remains vertical to the horizontal plane. During the rotation of the rod 16, the rod 16 scrapes the front and rear sides of the electromagnet 13 to scrape off the iron filings on the front and rear sides of the electromagnet 13, thereby improving the subsequent adsorption efficiency of the electromagnet 13 for iron filings; thereby improving the adsorption efficiency of the electromagnet 13, and then avoiding the iron filings in the activated carbon raw material affecting the subsequent processes. ;
