Description

Technical Field

[0001] This invention relates to the field of permanent magnet processing, and more particularly to a magnetic raw material dehydrator. Background Technology

[0002] Magnetite is the raw material for producing permanent magnets. Magnetite mining involves a large amount of water, and the moisture content is even higher during tailings washing. Before further processing, the magnetic raw materials need to be dehydrated, and vibrating dewatering screens are common equipment for dewatering magnetic raw materials.

[0003] The vibrating dewatering screen uses a vibrating device to make the screen plate shake forward. The magnetic raw material gradually moves upward along the bottom of the screen plate. During the upward movement of the magnetic raw material, water is removed, and the dewatering effect is good. However, the magnetic raw material that has been dewatered at the top of the screen plate has a large adhesion, which will hinder the conduction of the raw material, resulting in a limited discharge speed and the dewatering processing efficiency needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to solve the following problems existing in the prior art: The vibrating dewatering screen causes the screen plate to shake forward through the vibrating device, and the magnetic raw material gradually moves upward along the bottom of the screen plate. During the upward movement of the magnetic raw material, water is removed, and the dewatering effect is good. However, the magnetic raw material that has been dewatered at the top of the screen plate has a large adhesion, which will hinder the conduction of the raw material, resulting in a limited discharge speed and the dewatering processing efficiency needs to be improved.

[0005] To address the problems existing in the prior art, the present invention provides a magnetic raw material dehydrator, including a discharge hopper, which is connected from top to bottom, and the feeding station and the unloading station are symmetrically distributed along the edge of the discharge hopper;

[0006] The screen box has a turntable mounted on the outside of the discharge hopper, and several screen boxes are arranged in a ring around the turntable. The bottom plate of the screen box extends inclined to the edge of the screen box near the discharge hopper to form a discharge end. The discharge end of the screen box located at the feeding station is raised and can store material. The discharge end of the screen box located at the unloading station is lowered and discharges material from the discharge end into the discharge hopper.

[0007] The first motor drives the turntable to rotate the screen box around the discharge hopper. During the process of the screen box rotating from the loading station to the unloading station, the discharge end gradually sinks from the top.

[0008] Preferably, a ring frame is provided below the screen box, the ring frame is fixed to the discharge hopper, a bracket is fixed at the bottom of the screen box, one end of the bracket is rotatably connected to the turntable, the other end of the bracket is pressed on the surface of the ring frame, and several protrusions are evenly provided on the surface of the ring frame.

[0009] Preferably, the protrusion is a beveled triangle, and a roller is rotatably mounted on the surface of the bracket, the roller rolling in contact with the protrusion.

[0010] Preferably, the discharge hopper, ring frame, and screen box are inclined as a whole, with the feeding station located on the lowest side of the inclination of the discharge hopper and the unloading station located on the highest side of the inclination of the discharge hopper.

[0011] Preferably, the discharge hopper is horizontal, the ring frame is inclined, the loading station is located on the lowest inclined side of the ring frame, and the unloading station is located on the highest inclined side of the ring frame.

[0012] Preferably, the bottom plate of the screen box forms a continuously descending stepped shape towards the discharge hopper.

[0013] Preferably, the bottom of the discharge hopper has a discharge assembly, which includes a feed pipe rotatably connected to the bottom opening of the discharge hopper. The feed pipe is connected to a guide pipe, and an auger is rotatably installed inside the guide pipe. The auger is connected to a second motor.

[0014] Compared with related technologies, the magnetic raw material dehydrator provided by the present invention has the following beneficial effects:

[0015] This invention utilizes a rotary drive to produce several screen boxes. These screen boxes sequentially pass through a feeding station to receive and feed materials. As the screen boxes rotate from the feeding station to the feeding station, they vibrate, promoting the dehydration and discharge of the magnetic raw materials inside. When the screen box reaches the discharging station, the raw materials have already completed dehydration. The discharge end of the screen box at the discharging station points downwards towards the discharge hopper, and the vibration causes the raw materials inside the screen box to be discharged into the discharge hopper. This achieves continuous dehydration of magnetic raw materials at multiple stations with high dehydration efficiency. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 5 As shown, a magnetic raw material dewatering device has a cylindrical discharge hopper 1, which is open from top to bottom. The bottom of the discharge hopper 1 is funnel-shaped. A turntable 2 is rotatably mounted on the outside of the top opening of the discharge hopper 1 via a bearing. Several screen boxes 3 are distributed around the turntable 2. The screen boxes 3 have a fan-shaped outline. The gap between adjacent screen boxes 3 is no more than 2 cm. A bracket 7 is fixed at the bottom of the screen box 3. The bracket 7 is rotatably connected to the turntable 2. A ring frame 4 is sleeved on the outside of the turntable 2. The ring frame 4 is distributed below the screen boxes 3 and is fixed to the discharge hopper 1. Several protrusions 41 are evenly arranged on the surface of the ring frame 4. A roller 71 is rotatably mounted on the end of the bracket 7. The roller 71 presses on the surface of the protrusions 41.

[0029] like Figure 6 , Figure 7 As shown, the three sides of the screen box 3 have surrounding plates, and the bottom plate of the screen box 3 extends towards the edge of the screen box 3 to form a discharge end. The bottom plate of the screen box 3 is made of screen mesh.

[0030] like Figure 5 As shown, the lower part of the turntable 2 is fixed with a gear ring, the first motor 6 is installed outside the discharge hopper 1, the output shaft of the first motor 6 is connected to the gear ring through gear meshing, and a cover 21 is set on the outside of the gear ring to cover the gear and the gear ring.

[0031] The feeding station and the unloading station are symmetrically distributed on the edge of the discharge hopper 1. The discharge hopper 1, the ring frame 4, and the screen box 3 are tilted as a whole. The discharge end of the screen box 3 located at the feeding station is raised, and the discharge end of the screen box 3 located at the unloading station is lowered.

[0032] The first motor 6 drives the turntable 2 to slowly rotate all the screen boxes 3 around the discharge hopper 1. The screen boxes 3 pass through the feeding station in sequence to receive the material. The mined magnetic raw material falls from the feeding station into the screen box 3. During the rotation of the screen box 3 from the feeding station to the discharge station, the roller 71 rolls along the ring frame 4. Through the rolling contact between the roller 71 and the protrusion 41, the screen box 3 vibrates, which promotes the dehydration and discharge of the magnetic raw material in the screen box 3. When the screen box 3 rotates to the discharge station, the raw material has completed the dehydration work. The discharge end of the screen box 3 at the discharge station sinks down and points towards the discharge hopper 1. Under the vibration state, the raw material in the screen box 3 is discharged into the discharge hopper 1, thereby realizing the continuous dehydration of the magnetic raw material at multiple stations.

[0033] like Figure 5 As shown, the protrusion 41 is a sloping triangular shape, which avoids the protrusion 41 from causing great obstruction to the movement of the roller 71, ensuring that the screen box 3 produces stable shaking during rotation, and the rotational resistance is small.

[0034] like Figure 6 , Figure 7 As shown, the bottom plate of the screen box 3 forms a continuously descending stepped shape towards the discharge hopper 1. When the feeding station feeds the screen box 3, the discharge end tilts upward. The magnetic raw material is blocked by the stepped bottom plate of the screen box 3 and is relatively evenly distributed on the bottom surface of the screen box 3, maintaining a large dehydration area and avoiding the phenomenon of the raw material sliding and accumulating due to the inclined surface, which would hinder dehydration.

[0035] like Figure 8 As shown, the bottom of the discharge hopper 1 has a discharge assembly 5, which includes a feed pipe 51. The feed pipe 51 is rotatably connected to the bottom opening of the discharge hopper 1. The feed pipe 51 is connected to a guide pipe 52. An auger 54 is rotatably installed inside the guide pipe 52. The auger 54 is connected to a second motor 53.

[0036] The raw materials collected in the discharge hopper 1 are introduced into the guide pipe 52 through the feed pipe 51. The second motor 53 is turned on to drive the auger 54 to rotate. The auger 54 discharges the raw materials in a concentrated manner. Since the feed pipe 51 is rotatably connected to the bottom opening of the discharge hopper 1, the discharge direction can be easily adjusted.

[0037] Example 2

[0038] like Figure 3 , Figure 4 As shown, the discharge hopper 1 is in a horizontal state, while the ring frame 4 is in an inclined state. The loading station is located on the lowest side of the inclined ring frame 4, and the unloading station is located on the highest side of the inclined ring frame 4.

[0039] As the screen box 3 rotates from the loading station to the unloading station, it is resisted by the ring frame 4, causing the discharge end of the screen box 3 to gradually swing downward until the discharge end sinks and aligns with the discharge hopper 1, discharging the raw material in the screen box 3 downward.
