Description

Technical Field

[0001] This utility model relates to the field of refractory furnace charge processing technology, specifically to a refractory furnace charge screening and iron removal device. Background Technology

[0002] Refractory materials are a type of monolithic refractory material that is constructed by ramming (manually or mechanically) and hardened under high temperature. They are mainly used for filling, repairing, or lining protection of industrial kilns. Refractory materials are mostly produced by crushing and processing raw materials or recycled refractory materials. Both raw materials and recycled waste refractory materials contain iron. If the iron content is too high, it will affect the quality of the refractory material.

[0003] Currently, when performing iron removal screening on refractory furnace materials, the crushed refractory furnace materials need to be put into a container equipped with electromagnetic devices. Ferromagnetic impurities are retained in the container by passing magnets through it. After iron removal, the machine needs to be stopped, the impurities need to be cleaned manually, and the furnace materials need to be collected separately. This results in low production efficiency and cumbersome operation, which affects continuous operation. Utility Model Content

[0004] The purpose of this invention is to provide a refractory furnace charge screening and iron removal device to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

An electromagnetic structure is provided between one end of the two side plates and the electromagnetic structure is located inside the conveyor belt.

[0007] Preferably, a connecting rod is fixedly connected between the middle of the two side plates, and support legs are fixedly connected to both ends of the bottom of the two side plates.

[0008] Preferably, a transmission roller is rotatably connected between one end of the two side plates, and a rotating shaft is rotatably connected between the other ends of the two side plates. Both ends of the rotating shaft are fixedly connected to driven wheels, and the transmission roller is connected to the two driven wheels via a conveyor belt. A motor for driving the transmission roller is fixedly installed on one of the side plates, and the input end of the motor is electrically connected to the output end of the controller.

[0009] Preferably, the edge of the conveyor belt abuts against the inner wall of the side plate, and a number of partition strips are fixedly connected to the surface of the conveyor belt.

[0010] Preferably, the stirring rod structure includes a second rotating shaft rotatably connected to the bottom opening of the hopper, a plurality of stirring plates are fixedly connected to the second rotating shaft, and a second motor for driving the second rotating shaft to rotate is fixedly installed on the side wall of the hopper. The input end of the second motor is electrically connected to the output end of the controller.

[0011] Preferably, each pair of agitators is designed to be perpendicular to the other at 90 degrees, and the length of the agitator is adapted to the width of the bottom opening of the hopper, which is smaller than the width of the conveyor belt.

[0012] Preferably, the electromagnetic structure includes a U-shaped magnetic guide plate fixedly installed between two side plates, an electromagnet is fixedly installed on the inner wall of the U-shaped magnetic guide plate, and the magnetic poles of the electromagnet are in contact with the U-shaped magnetic guide plate.

[0016] The beneficial effects are:

[0017] By feeding the crushed refractory charge into the hopper, the charge is evenly fed onto the conveyor belt by rotating the agitator. As the conveyor belt rotates, iron impurities on its surface are adsorbed onto the surface of the conveyor belt when passing through the U-shaped magnetic guide plate area and rotate with it. When the pure charge is conveyed to the end, it automatically falls off due to gravity and is guided by the inclined guide plate to an independent collection container. The adsorbed iron impurities rotate with the conveyor belt to the bottom and continue to move out of the range of the U-shaped magnetic guide plate before falling into the receiving box by gravity. This achieves continuous separation of impurities from the charge, realizes dynamic conveying and real-time iron removal of the charge, and improves production efficiency.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] See Figures 1-4 As shown, this utility model provides a refractory furnace charge screening and iron removal device, including a controller 7 and two side plates 1. A conveyor belt 3 is rotatably connected between the two side plates 1. A hopper 4 is fixedly connected above the two side plates 1 by a support frame. The bottom of the hopper 4 is provided with a stirring rod structure 5 to avoid clogging of the furnace charge. An electromagnetic structure is provided between one end of the two side plates 1, and the electromagnetic structure is located inside the conveyor belt 3.

[0027] Specifically, a connecting rod 8 is fixedly connected between the middle of the two side plates 1, and support legs 2 are fixedly connected to both ends of the bottom of the two side plates 1. The connecting rod 8 can make the connection between the two side plates 1 more secure and stable, and the support legs 2 can provide space for the placement of the receiving box 11.

[0028] Reference Figure 3As shown, a transmission roller 301 is rotatably connected between one end of the two side plates 1, and a rotating shaft 302 is rotatably connected between the other ends of the two side plates 1. Both ends of the rotating shaft 302 are fixedly connected to driven wheels 303, and the transmission roller 301 and the two driven wheels 303 are connected by a conveyor belt 3. A motor 304 for driving the transmission roller 301 to rotate is fixedly installed on one of the side plates 1. The input end of the motor 304 is electrically connected to the output end of the controller 7. The conveyor belt 3 is driven by the motor 304 through the transmission roller 301 and the driven wheels 303. The furnace charge falls evenly between several partition strips 305 and moves with them. Since the closed end of the U-shaped magnetic plate 6 is designed to be the same diameter as the driven wheel 303, the driven wheel 303 can drive the conveyor belt 3 to rotate more stably, avoiding the situation of falling off.

[0029] As an optional implementation, the edge of the conveyor belt 3 abuts against the inner wall of the side plate 1, and a number of partition strips 305 are fixedly connected to the surface of the conveyor belt 3. The abutment between the conveyor belt 3 and the side plate 1 can prevent the furnace charge from falling through the gap. The evenly distributed partition strips 305 can form a thin layer conveying state, which can improve the subsequent iron removal effect.

[0030] Reference Figure 2 As shown, the stirring rod structure 5 includes a rotating shaft 501 rotatably connected to the bottom opening of the hopper 4. Several stirring plates 502 are fixedly connected to the rotating shaft 501, and a motor 503 for driving the rotating shaft 501 to rotate is fixedly installed on the side wall of the hopper 4. The input end of the motor 503 is electrically connected to the output end of the controller 7. Each pair of stirring plates 502 is designed to be perpendicular to each other at 90 degrees, and the length of the stirring plates 502 is adapted to the width of the bottom opening of the hopper 4. The bottom opening width of the hopper 4 is smaller than the width of the conveyor belt 3. The crushed refractory furnace material is put into the hopper 4. The motor 503 drives the several stirring plates 502, which are distributed perpendicularly at 90 degrees, to continuously stir the bottom furnace material, effectively preventing the furnace material from being blocked at the discharge port. As the stirring plates 502 rotate, the furnace material is ensured to be evenly discharged to the conveyor belt 3. The bottom opening width of the hopper 4 is smaller than the width of the conveyor belt 3, which can prevent the furnace material from falling to the outside of the conveyor belt 3 when it falls.

[0031] Reference Figure 3As shown, the electromagnetic structure includes a U-shaped magnetic plate 6 fixedly installed between two side plates 1. An electromagnet 9 is fixedly installed on the inner wall of the U-shaped magnetic plate 6, and the magnetic poles of the electromagnet 9 are in contact with the U-shaped magnetic plate 6. The input end of the electromagnet 9 is electrically connected to the output end of the controller 7. The U-shaped magnetic plate 6 is made of soft iron, and the closed end of the U-shaped magnetic plate 6 is sleeved on the outside of the rotating shaft 302. The outer wall of the U-shaped magnetic plate 6 is in contact with the inner wall of the conveyor belt 3. The diameter of the closed end of the U-shaped magnetic plate 6 is the same as the diameter of the driven wheel 303. When the furnace charge passes through the electromagnetic structure inside the conveyor belt 3, the controller 7... When the electromagnet 9 is energized, a strong magnetic field is generated, which simultaneously magnetizes the U-shaped magnetic plate 6. At this time, both the upper and lower sides of one end of the conveyor belt 3 have magnetic force. The pure furnace charge automatically falls off at the end of the conveyor belt 3 due to gravity and is guided by the inclined guide plate 10 to the independent collection container. The iron impurities adsorbed by the U-shaped magnetic plate 6 continue to move with the conveyor belt 3 (after rotating to the bottom) to the non-magnetic field area (located at the bottom of the conveyor belt 3 and moved out of the range of the U-shaped magnetic plate 6) and fall into the receiving box 11 with gravity, realizing the continuous separation of impurities from the furnace charge. Since the closed end of the U-shaped magnetic plate 6 is designed with the same diameter as the driven wheel 303, the magnetic field coverage is without dead angles.

[0032] Specifically, a receiving box 11 is placed below the conveyor belt 3, and an inclined guide plate 10 is fixedly connected to one end of the two side plates 1. The pure furnace charge automatically falls off at the end of the conveyor belt 3 due to gravity and is guided to an independent collection container through the inclined guide plate 10. The adsorbed iron impurities continue to move with the conveyor belt 3 to the non-magnetic field area (located at the bottom of the conveyor belt 3 and moved out of the range of the U-shaped magnetic guide plate 6) and fall into the receiving box 11 with gravity, realizing the continuous separation of impurities from the furnace charge.

[0033] Reference Figure 4 As shown, the partition strip 305 includes a plate body, the width of the two ends of the plate body is greater than the width in the middle, and the two side walls of the partition strip 305 are inclined. When the two side walls of the partition strip 305 are inclined, the concave inclined design of the two side walls of the partition strip 305 allows iron impurities or furnace charge to converge to the middle with the inclined side walls of the partition strip 305 when moving with the conveyor belt 3. When the iron impurities move to the non-magnetic field area, they can converge to the middle of the conveyor belt 3 with the inclined surface, avoiding them from scattering when falling.

[0034] The working principle of this utility model:

[0035] The crushed refractory charge is fed into the hopper 4. Motor 2 503 drives several agitator plates 502, which are vertically distributed at 90 degrees, to continuously agitate the bottom charge, effectively preventing blockage at the discharge port and ensuring that the charge is evenly fed onto the conveyor belt 3. The conveyor belt 3 is driven by motor 1 304 through the drive roller 301 and driven wheel 303. The charge falls evenly between several partition strips 305 and moves with them. When the charge passes through the electromagnetic structure inside the conveyor belt 3, the controller 7 energizes the electromagnet 9 to generate a strong magnetic field. The U-shaped magnetic guide plate 6 (made of soft iron) concentrates the magnetic field in the area of ​​the conveyor belt 3, adsorbing ferromagnetic impurities. The pure charge automatically falls off at the end of the conveyor belt 3 due to gravity and is guided by the inclined guide plate 10 to an independent collection container. The adsorbed iron impurities continue to move with the conveyor belt 3 to the non-magnetic field area (located at the bottom of the conveyor belt 3 and moved out of the range of the U-shaped magnetic guide plate 6) and fall into the receiving box 11 by gravity, realizing the continuous separation of impurities from the charge.
