Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement production equipment, and more specifically, to a waste residue separation device for a cement production line. Background Art
[0002] Cement, a powdered hydraulic inorganic cementitious material, becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly cement materials such as sand and stone together. During the production process, cement clinker (and retarder, performance adjustment material, etc.) needs to be ground to a suitable particle size. However, the crushed iron slag enters the finished cement warehouse together with the cement. The iron slag in the cement becomes a major problem in cement packaging, because the iron slag will frequently block the feeding nozzle of the packaging machine during cement packaging, causing large deviations in the weight of the cement bag or loss of control of the feeding nozzle. At this time, a cement waste slag separation device is needed to clean the iron slag.
[0003] Conventional cement production lines use cement waste slag separation devices, which generally use magnets to remove the iron slag from the material. However, the iron slag and cement are usually in a static state inside the device, resulting in poor removal of the iron slag and inability to perform comprehensive slag removal. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a waste slag separation device for a cement production line. When the material is dropped through the feed hopper, the electromagnetic plate can absorb part of the iron slag, and the stirring rod stirs and disperses the material to prevent the material from accumulating on one side of the feed port. At the same time, the material is put into a moving state, so that the iron slag in the material can be fully absorbed by the electromagnetic plate, thereby significantly improving the separation effect of the waste slag.
[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a waste slag separation device for a cement production line comprises a separation box, a feed port is provided on the separation box, a feed hopper is arranged at the feed port, a material conveyor belt is arranged on one side of the separation box, the output end of the material conveyor belt is located above the feed hopper, a first motor is symmetrically arranged on both sides of the bottom of the separation box, the output shaft of the first motor passes through the separation box and is transmission-connected to a stirring shaft, a plurality of stirring rods are arranged on the stirring shaft, a cement discharge port is provided at the bottom of the separation box, a rotating shaft is rotatably connected in the separation box, a second motor for driving the rotating shaft to rotate is arranged on the outer wall of the separation box, connecting rods are symmetrically sleeved on the rotating shaft, an electromagnetic plate is arranged between the lower ends of the two connecting rods, a slag guide plate is arranged on the side of the bottom of the inner wall of the separation box away from the feed port, and an iron slag discharge port corresponding to the lower end position of the slag guide plate is provided at the bottom of the separation box.
[0006] The utility model is further configured as follows: the bottom of the electromagnetic plate is in an upwardly concave structure.
[0007] The utility model is further configured as follows: a limiting block is arranged on the inner wall of the separation box on the side close to the feed inlet, and the limiting block is used to abut against the electromagnetic plate.
[0008] The utility model is further configured as follows: a reinforcing rib is arranged on the inner wall of the separation box, and the other end of the reinforcing rib is fixedly connected to the bottom of the slag guide plate.
[0009] The utility model is further configured as follows: the bottom of the separation box is provided with supporting feet, and the number of the supporting feet is four.
[0010] In summary, the utility model has the following beneficial effects:
[0011] As the material is dropped through the feed hopper, the electromagnetic plate can absorb part of the iron slag, and the stirring rod stirs and disperses the material to prevent it from accumulating on one side of the feed port. At the same time, the material is kept in motion, so that the iron slag in the material can be fully absorbed by the electromagnetic plate, significantly improving the separation effect of the waste slag.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0019] Additionally, the bottom of the electromagnetic plate 9 is in an upwardly concave structure, which can expand the adsorption area of the electromagnetic plate 9 on the iron slag, thereby improving the working efficiency of the waste slag separation device.
[0020] A limit block 12 is fixedly provided on the inner wall of the separation box 1 near the feed port. The limit block 12 is used to resist the electromagnetic plate 9. The setting of the limit block 12 helps to control the movement stroke of the electromagnetic plate 9, ensuring that the electromagnetic plate 9 is in a horizontal state to adsorb iron slag so that it has the largest effective adsorption area.
[0021] A reinforcing rib 13 is fixedly provided on the inner wall of the separation box 1, and the other end of the reinforcing rib 13 is fixedly connected to the bottom of the slag guide plate 10. The reinforcing rib 13 further supports the slag guide plate 10, thereby extending the structural strength of the slag guide plate 10 for receiving the falling iron slag and extending its service life.
[0022] The bottom of the separation box 1 is fixedly provided with supporting feet 14, and the number of the supporting feet 14 is four, which can improve the stability and load-bearing capacity of the separation box 1 and ensure that the entire device is more stable during operation.
[0023] Working principle: When the device is in use, the electromagnetic plate 9 is controlled to be energized, and then the material is fed into the separation box 1 through the feed hopper 2 through the material conveyor belt 3. During the falling process of the material, the electromagnetic plate 9 can absorb part of the iron slag, and then the stirring shaft 4 rotates to drive the stirring rod 5 to stir and disperse the material to prevent the material from accumulating on one side of the feed port, and at the same time, the material is in a state of motion to prevent the iron slag in the lower layer of the material from continuously accumulating in the lower layer and being unable to be adsorbed by the electromagnetic plate 9. After the slag removal is completed, the cement is discharged from the cement discharge port 6, and the second motor drives the rotating shaft 7 to rotate, and then drives the electromagnetic plate 9 to rotate away from the top of the stirring rod 5 through the connecting rod 8, and then rotates to the top of the slag guide plate 10, and controls the electromagnetic plate 9 to be powered off, so that the iron slag loses its adsorption effect and falls under the action of gravity, and is guided by the slag guide plate 10 to discharge and collect the iron slag at the discharge port 11, and then the material conveyor belt 3 continues to convey the next batch of materials into the separation box 1, and so on, for continuous waste slag separation.
[0024] The first motor, the second motor and the electromagnetic plate 9 of the utility model are all electrically connected to the controller to achieve regulation and coordination. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
