Description

Technical Field

[0001] The utility model relates to the field of ferromolybdenum smelting residue recovery equipment, and in particular to a novel ferromolybdenum smelting slag recovery equipment. Background Art

[0002] At present, residues will be produced in the smelting process of ferromolybdenum. First, the residues with high metal content are directly picked out manually, and then the residues that are not easy to pick out are put into the filter screen set on the ground. Then the residues pass through the filter screen and enter the roller crusher for the first crushing. After the crushing is completed, it is fed into the ball mill equipment set on the ground through the feeding equipment. Then it is crushed for the second time in the ball mill to further increase the crushing particle size. Since ferromolybdenum is hard, the crushing particle size of the remaining residues will be smaller. After the double crushing is completed, it needs to be passed into the screening equipment to separate the metal residue (there are differences in particle size) from other residues. After the separation is completed, the magnetic separation process (small-particle metal residue and other residues) is finally carried out. After the magnetic separation is completed, all the metal residues are put into the smelting furnace for processing and then recycled.

[0003] However, the existing screening equipment and magnetic separation equipment work asynchronously, and the magnetic separation can only be started when the screening amount is large enough. This requires manual supervision and manual start of the magnetic separation equipment. The process is not convenient enough, and the recovery effect of ferromolybdenum needs to be further improved. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes a new type of ferromolybdenum smelting slag recovery equipment.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A new type of ferromolybdenum smelting slag recovery equipment, including a screen, a roller crushing device, a feeding device, a ball mill and a discharge chute, and also includes a screening box, an arc filter, a discharge pipe, a first vibration motor, a front and rear moving assembly, a mounting frame, a separation box, a guide plate, an electromagnetic plate, a discharge channel, a second vibration motor, an impurity box and two metal boxes.

[0007] The screening box includes a feed hopper and a discharge port, and the feed hopper is located below the end of the discharge chute;

[0008] The curved filter is tilted and arranged inside the screening box;

[0009] The feed pipe is arranged on the screening box and one end of the feed pipe passes through the screening box and is connected with the bottom of the arc-shaped filter screen;

[0010] The first vibration motor is arranged on the screening box;

[0011] The forward and backward moving assembly is arranged on the ground and is connected to a mounting frame;

[0012] The two separation boxes are symmetrically arranged on the mounting frame, and the discharge port is located above one of the separation boxes;

[0013] A plurality of guide plates are tilted and staggeredly arranged inside the separation box, and the ends of the guide plates are spaced apart from the inner wall of the separation box;

[0014] The electromagnetic plate is arranged on the material guide plate;

[0015] The material discharge channel is opened at the bottom of the separation box;

[0016] The second vibration motor is arranged on the separation box;

[0017] The impurity box and the metal box are both arranged on the ground, and the metal boxes are symmetrically distributed front to back with respect to the impurity box. The impurity box is located below one of the material discharge channels.

[0018] Furthermore, the forward and backward moving assembly includes a telescopic part, a ground rail and a connecting rod. The telescopic part and the ground rail are symmetrically arranged on the ground. A connecting rod connected to the telescopic part is arranged on the ground rail, and one end of the two connecting rods is connected to a mounting frame.

[0019] The above solution can realize the alternating movement of the positions of the two separation boxes by moving the components forward and backward, thereby completing the automatic unloading of small-sized metal residues that have been magnetically separated and adsorbed on the electromagnetic plate into the metal box.

[0020] Furthermore, the length of the guide plate at the bottom is shorter than the lengths of the remaining guide plates.

[0021] Furthermore, a slope is symmetrically provided at the inner bottom end of the separation box.

[0022] The above solution can reduce the probability of other residues and small-sized metal residues accumulating and remaining at the bottom of the separation box through the inclined platform.

[0023] Furthermore, the other end of the feed pipe is located above a large-grained metal collection box arranged on the ground.

[0024] Furthermore, the electromagnetic plates in the two separation boxes are electrically connected to the controller independently.

[0025] Furthermore, the impurity box, the metal box and the large-particle metal collection box are all provided with material level sensors.

[0026] Furthermore, the device further comprises a plurality of voice prompters corresponding one to one with the plurality of material level sensors and electrically connected thereto.

[0027] The above scheme can independently detect the storage volume in multiple storage containers through multiple level sensors. When a storage container is about to be full, the level sensor will feedback a signal to the controller, and the controller will then control the voice prompter to issue a prompt and stop the recycling process at the same time. The staff will then replace the storage container to avoid material overflow.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] Compared with the existing technology, the screening equipment and magnetic separation equipment in this device work synchronously and the magnetic separation effect is comprehensive and stable. The large-particle metal residue is directly screened and finally automatically stored in the large-particle metal collection box. The small-particle metal residue and other residues pass through the arc filter and then enter the two separation boxes in turn for alternating magnetic separation to achieve separation. After the final separation, the small-particle metal residue and other residues are independently collected into the corresponding containers. During the recycling process, there is no need for manual supervision and manual start of magnetic separation, and the recovery effect of molybdenum iron is further improved.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0037] like Figures 1 to 4 As shown, a novel ferromolybdenum smelting slag recovery device includes a screen 1, a roller crushing device 2, a feeding device 3, a ball mill 4 and a discharge chute 5, and also includes a screening box 6, an arc filter 63, a discharge pipe 64, a first vibration motor 65, a front and rear moving component, a mounting frame 8, a separation box 9, a guide plate 91, an electromagnetic plate 92, a discharge channel 93, a second vibration motor 94, an impurity box 96 and two metal boxes 97.

[0038] The screening box 6 includes a feed hopper 61 and a discharge port 62, and the feed hopper 61 is located below the end of the discharge chute 5;

[0039] The curved filter screen 63 is tilted and arranged inside the screening box 6;

[0040] A feed pipe 64 is provided on the screening box 6 and one end of the feed pipe 64 passes through the screening box 6 and is connected to the bottom of the arc-shaped filter screen 63. The other end of the feed pipe 64 is located above a large-particle metal collection box provided on the ground. The large-particle metal collection box is shown in the figure but is not numbered.

[0041] The first vibration motor 65 is provided on the screening box 6;

[0042] The forward and backward moving assembly is set on the ground and connected to the mounting frame 8;

[0043] The two separation boxes 9 are symmetrically arranged on the mounting frame 8, and the discharge port 62 is located above one of the separation boxes 9;

[0044] Several guide plates 91 are tilted and staggered inside the separation box 9, and the ends of the guide plates 91 are spaced apart from the inner wall of the separation box 9 (for further optimization, the length of the guide plate 91 at the bottom is shorter than that of the other guide plates 91);

[0045] The electromagnetic plate 92 is arranged on the material guide plate 91;

[0046] The material discharge channel 93 is opened at the bottom of the separation box 9 and the inner bottom end of the separation box 9 is symmetrically provided with an inclined platform 95;

[0047] The second vibration motor 94 is provided on the separation box 9;

[0048] The impurity box 96 and the metal box 97 are both set on the ground, and the metal box 97 is symmetrically distributed front to back with respect to the impurity box 96 . The impurity box 96 is located below one of the discharge channels 93 .

[0049] In a further refinement of the embodiment of the present invention, the forward and backward moving components include a telescopic member 71, a ground rail 72 and a connecting rod 73. The telescopic member 71 and the ground rail 72 are symmetrically arranged on the ground. A connecting rod 73 connected to the telescopic member 71 is arranged on the ground rail 72, and one end of the two connecting rods 73 is connected to the mounting frame 8.

[0050] It should be noted that the first vibration motor 65, telescopic member 71, electromagnetic plate 92 and second vibration motor 94 are all electrically connected to the controller, which is not shown in the figure. It should be noted that the electromagnetic plates 92 in the two separation boxes 9 are independently electrically connected to the controller.

[0051] The workflow of this utility model:

[0052] First, the mixed residue after the secondary crushing by the ball mill 4 will flow from the feed hopper 61 into the screening box 6. At this time, the controller controls the first vibration motor 65 to work, and then the hard and large-grained metal will remain above the curved filter 63 and then move along the curved filter 63 to the discharge pipe 64 and finally be collected and stored in the large-grained metal collection box;

[0053] The small-sized metal residues and other residues can finally flow out of the screening box 6 through the arc-shaped filter screen 63, and then this part of the mixed residue will be passed into the separation box 9 located in the front, and then the electromagnetic plate 92 in the separation box 9 located in the front is energized to realize magnetic separation and adsorption of the small-sized metal residues. At the same time, the controller controls the second vibration motor 94 to work to realize the directional flow of the remaining residues along the guide plate 91. The purpose of setting a plurality of staggered guide plates 91 is to prolong the residence time of the mixed residues in the separation box 9 so that the small-sized metal residues therein can be adsorbed and magnetically separated more thoroughly, and then the other residues flow from the discharge channel 93 to the impurity box 96 for collection;

[0054] When the electromagnetic adsorption of the separation box 9 in the front has preset a time interval, it is necessary to unload the small-sized metal residues to avoid the accumulation of too much small-sized metal residues affecting the subsequent magnetic separation effect. At this time, the controller controls the front and rear moving components to work and then change the positions of the two separation boxes 9. Then the empty separation box 9 at the rear moves to the bottom of the discharge port 62 and controls the electromagnetic plate 92 inside it to be energized immediately. At this time, the discharge channel 93 of the separation box 9 in the front is just above the metal box 97 on the front side of the impurity box 96. Then the controller controls the electromagnetic plate 92 in the front separation box 9 to cut off the power and continue to vibrate so that the small-sized metal residues can be collected and stored in one of the metal boxes 97. Similarly, when the separation box 9 at the rear has also collected for the preset time interval, the two separation boxes 9 change positions again. At this time, the metal in the front separation box 9 has been completely unloaded, and then the small-sized metal residues in the rear separation box 9 can be automatically unloaded and collected in the metal box 97 on the rear side of the impurity box 96.

[0055] By cycling this process, the unloading process of the small-sized metal residues magnetically separated in the two separation boxes 9 can be realized successively, and the independent collection of other residues and small-sized metal residues can be realized at the same time.

[0056] Finally, the metal box 97 and the metal residue in the large-grained metal collection box are put into a smelting furnace for smelting and recovery for reuse;

[0057] Compared with the existing technology, the screening equipment and magnetic separation equipment in this device work synchronously and the magnetic separation effect is comprehensive and stable. The large-particle metal residue is directly screened and automatically stored in the large-particle metal collection box. The small-particle metal residue and other residues are then passed into the two separation boxes 9 in turn through the arc filter 63 for alternating magnetic separation to achieve separation. After the final separation, the small-particle metal residue and other residues are independently collected into corresponding containers. During the recycling process, there is no need for manual supervision and manual start of magnetic separation, and the recovery effect of molybdenum iron is further improved.

[0058] In other embodiments, the impurity box 96, the metal box 97 and the large-particle metal collection box are all provided with material level sensors (specifically, ultrasonic material level sensors);

[0059] A further optimization of the above embodiment further includes multiple voice prompters corresponding to and electrically connected to the multiple material level sensors. This embodiment is not shown in the figure and is an extension of the solution. The material level sensor specifically adopts an ultrasonic material level sensor. This embodiment can independently detect the storage volume in multiple storage containers through multiple ultrasonic material level sensors. When a storage container is about to be full, the material level sensor immediately feeds back a signal to the controller, and then the controller controls the voice prompter to issue a prompt and stop the recycling process at the same time, so that the staff can replace the storage container to avoid material overflow.

[0060] It should be noted that the device can be temporarily shut down during the process of replacing the storage container, and the replaced metal storage container can then be transferred to the smelting furnace for material recovery processing, while the other replaced residue storage containers can be directly discarded for other residues.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
