Description

Technical Field

[0001] This utility model applies to the field of magnetic separator feeding technology, and particularly relates to a vibrating feeding device. Background Technology

[0002] Currently, magnetic separators are used for screening iron powder and other materials in recycled powdery materials. After the slurry flows into the tank through the feed box, the mineral particles enter the feed area of ​​the tank in a loose state under the action of the water flow from the feed spray pipe. Under the action of the magnetic field, the magnetic mineral particles undergo magnetic aggregation to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are attracted to the magnetic poles by the magnetic force in the slurry and are adsorbed on the cylinder, thereby realizing the screening of iron powder raw materials inside the slurry.

[0003] However, currently, before screening iron powder mixed in with mineral slurry, a feeding mechanism is used to transport the raw material to be magnetically separated. Before this transport, the ore within the slurry tends to aggregate due to the rolling motion, making it impossible to separate the aggregated material during subsequent magnetic separation, thus reducing the quality of the magnetic separation. Therefore, we propose a vibrating feeder. Utility Model Content

[0004] The main purpose of this invention is to provide a vibrating feeder that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A vibrating feeder includes a receiving frame, a guide plate fixedly installed on the side of the receiving frame, baffle plates fixedly installed on both sides of the top of the guide plate at an incline, and a movable baffle plate detachably installed on the side of the receiving frame.

[0007] A transmission frame is fixedly installed on both ends of the outer surface of the receiving frame. A sliding frame is slidably installed on the outer side of the transmission frame. A moving mechanism is provided inside each transmission frame, and the moving mechanism is connected to the outer side of the sliding frame.

[0008] Electric push rods are vertically fixedly installed on both sides of the top of the sliding frame. A lifting plate is movably installed on the top of the inner side of the sliding frame. The bottom of the electric push rod drive shaft is fixedly connected to the top of the lifting plate through a coupling. A hollow frame is fixedly installed on the bottom surface of the lifting plate. A vibration disintegration mechanism is provided at the bottom of the lifting plate.

[0009] By adopting the above technical solution, the moving mechanism drives the position movement of the sliding frame and the dispersing rod, and under the driving action of the vibration dispersing mechanism, the moving plate and the dispersing rod can be provided with corresponding vibration force, so that the dispersing rod can reciprocate synchronously inside the receiving frame, thereby contacting and vibrating the accumulated material inside the receiving frame to disperse it, and avoiding the agglomeration of the slurry raw material inside the receiving frame, which would affect the subsequent magnetic separation and screening quality.

[0010] As an optional solution to the technical solution of this application, the moving mechanism includes a rotating lead screw and a transmission block. A rotating lead screw is rotatably installed inside each transmission frame via a bearing. A movable sleeve is movably sleeved on the outer surface of each rotating lead screw via a thread. A servo motor is fixedly installed on the inner side of each transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the top of the rotating lead screw side via a coupling. A transmission block is fixedly installed on the side of each movable sleeve, and the top of the other side of the transmission block is fixedly connected to the inner side of the bottom of the sliding frame. A limit groove is formed at the middle of the side of each transmission frame, and the transmission block is slidably installed inside the limit groove.

[0011] By adopting the above technical solution, the rotating screw drives the movable sleeve to move horizontally synchronously. Then, under the connecting and driving action of the transmission block, the sliding frame and the dispersing rod below it can move horizontally synchronously inside the receiving frame, so as to fully disperse the slurry raw materials accumulated in different positions inside the receiving frame.

[0012] As an optional solution to the technical solution of this application, the vibration disintegration mechanism includes a vibration motor and a disintegration rod. Vibration motors are fixedly installed on both sides inside the hollow frame. A movable plate is movably provided at the bottom of the hollow frame, and the bottom of the vibration motor drive shaft is fixedly connected to the top surface of the movable plate through a coupling.

[0013] By adopting the above technical solution, the vibration motor can provide the driving force required for the reciprocating vibration of the movable plate and the dispersing rod, so that the dispersing rod can dissolve the polymer inside the slurry.

[0014] As an optional solution to the technical solution of this application, each of the movable plates is vertically fixedly installed with a connecting screw, and there are several sets of connecting screws. Each connecting screw has a disintegrating rod screwed to its outer side by a thread.

[0015] By adopting the above technical solution, the dispersing rod can be twisted and disassembled through the structural action of the connecting screw, which makes it convenient for the operator to replace the dispersing rod regularly, thereby ensuring the vibration dispersing quality of the polymer inside the slurry.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A vibrating feeding device according to the present application comprises a horizontally movable sliding frame at the top of a receiving frame and an electric push rod on the outside of the sliding frame. Under the operation of the electric push rod, a corresponding vertical moving force can be provided to the lifting plate, so that the lifting plate can drive the dispersing rod below it to move vertically synchronously. After the dispersing rod moves synchronously into the receiving frame, under the driving action of the vibrating motor located at the bottom of the sliding frame, a corresponding vibration force can be provided to the moving plate and the dispersing rod, so that the dispersing rod can reciprocate synchronously inside the receiving frame. This can contact vibration and dispersing of the material accumulated inside the receiving frame, thereby preventing the agglomeration of the slurry raw material inside the receiving frame from affecting the subsequent magnetic separation and screening quality.

[0018] 2. A vibrating feeder according to the present application, by setting rotating screws inside the transmission frames on both sides of the receiving frame, can drive the movable sleeves fitted on its surface to move horizontally synchronously under the rotational transmission action of the rotating screws. Then, under the connecting transmission action of the transmission block, it can drive the sliding frame and the dispersing rod below it to move horizontally synchronously inside the receiving frame, so as to fully disperse the slurry raw materials accumulated in different positions inside the receiving frame, further improving the dispersing quality of the slurry raw materials and improving the quality of subsequent magnetic separation and screening.

[0023] like Figure 1-3As shown, this utility model provides a technical solution: a vibrating feeding device, wherein a transmission frame 2 is fixedly installed on both ends of the outer side of the receiving frame 1, and a sliding frame 21 is slidably installed on the outer side of the transmission frame 2. Each transmission frame 2 is provided with a moving mechanism inside, and the moving mechanism is connected to the outer side of the sliding frame 21.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, the moving mechanism includes a rotating lead screw 3 and a transmission block 32. Each transmission frame 2 has a rotating lead screw 3 rotatably mounted inside via a bearing. Each rotating lead screw 3 has a movable sleeve 31 threadedly fitted onto its outer surface. Each transmission frame 2 has a servo motor 33 fixedly mounted on its inner side. The transmission shaft of the servo motor 33 is fixedly connected to the top of the rotating lead screw 3 via a coupling. Each movable sleeve 31 has a transmission block 32 fixedly mounted on its side. The top of the other side of the transmission block 32 is fixedly connected to the inner bottom of the sliding frame 21. Each transmission frame 2 has a limiting groove 4 at its middle side. The transmission block 32 is slidably mounted inside the limiting groove 4.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, electric push rods 22 are vertically fixedly installed on both sides of the top of the sliding frame 21. A lifting plate 23 is movably installed on the top of the inner side of the sliding frame 21. The bottom of the drive shaft of the electric push rod 22 is fixedly connected to the top of the lifting plate 23 through a coupling. A hollow frame 24 is fixedly installed on the bottom surface of the lifting plate 23. A vibration dispersing mechanism is provided at the bottom of the lifting plate 23.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown in the figure, the vibration disintegration mechanism includes a vibration motor 25 and a disintegration rod 27. The vibration motor 25 is fixedly installed on both sides inside the hollow frame 24. A movable plate 26 is movably arranged at the bottom of the hollow frame 24. The bottom of the transmission shaft of the vibration motor 25 is fixedly connected to the top surface of the movable plate 26 through a coupling. A connecting screw 28 is vertically fixedly installed at the bottom of the movable plate 26. There are several sets of connecting screws 28. A disintegration rod 27 is screwed to the outside of each connecting screw 28 through a thread.

[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3As shown, a guide plate 11 is fixedly installed on the side of the receiving frame 1, and baffle plates 12 are fixedly installed on both sides of the top of the guide plate 11 at an incline. A movable baffle plate 13 is detachably installed on the side of the receiving frame 1.

[0028] During operation, the required magnetically screened slurry is poured into the receiving frame 1. An external control switch activates the electric actuator 22, causing it to rotate and drive the lifting plate 23, connected to the dispersing rod 27 below it, to move vertically in sync. Once the bottom of the dispersing rod 27 is close to the bottom surface of the receiving frame 1, the servo motor 33 is activated, causing the rotating screw 3 to rotate synchronously. Combined with the guiding and limiting effect of the limiting groove 4 on the transmission block 32, this allows the movable sleeve 31 fitted onto its surface to move horizontally in sync. Furthermore, under the connecting transmission action of the transmission block 32, the sliding frame 21 and the dispersing rod 27 below it can move synchronously in sync with the receiving frame. The frame 1 moves horizontally inside, and the vibration motor 25 is started synchronously. When it runs, the vibration force of the dispersing rod 27 is transmitted through the transmission connection of the movable plate 26, so that the dispersing rod 27 can reciprocate inside the receiving frame 1. Combined with the synchronous action of the sliding frame 21, the accumulated material in different positions inside the receiving frame 1 can be contacted and dispersed by vibration. After the material is fully dispersed, the movable baffle 13 is pulled to move it away from the right side of the receiving frame 1. The slurry raw material is then transported into the magnetic separator under the guidance of the guide plate 11 and the baffle plate 12 to perform magnetic treatment on the dispersed iron powder raw material inside the slurry.
