Detailed description of the invention
Fig. 1 is the structural schematic diagram of Nd-Fe-B permanent magnet waste residue crushing device proposed by the present invention.
Specific embodiment
Illustrate the contents of the present invention below in conjunction with specific embodiments.
As shown in Figure 1, Fig. 1 is the structural schematic diagram of Nd-Fe-B permanent magnet waste residue crushing device proposed by the present invention.
Referring to Fig.1, Nd-Fe-B permanent magnet waste residue crushing device proposed by the present invention, comprising: rack 1, broken case 2 and transmission
Device.
The broken case 2 is mounted in the rack 1, is connected with box for feeding odd 3 on the broken case 2.The box for feeding odd 3 one
Side is connected with feeding funnel 9, and the other side offers discharge port 10.Feeding spiro rod 4 is rotatably connected in the box for feeding odd 3, it is described to send
Expect that screw rod 4 is driven by motor 5 to rotate, the 5 shaft periphery of motor is set with first bevel gear 6, and the first bevel gear 6 engages
There is second bevel gear 7, the second bevel gear 7 is sleeved on 8 periphery of upright bar, and the upright bar is arranged perpendicular to the feeding spiro rod 4.
Material is poured into box for feeding odd 3 by feeding funnel 9, motor 5 drives feeding spiro rod 4 to rotate, and feeding spiro rod 4 was rotating
Material is oriented in journey, and material is sent out into discharge port 10.
Crushing mechanism is equipped with below 3 discharge port 10 of box for feeding odd.The crushing mechanism includes mutually matched first broken
Broken roller 11 and the second breaker roll 12.First breaker roll 11 and the second breaker roll 12 are driven by driving mechanism to be rotated, and described
The rotation direction of first breaker roll 11 and the second breaker roll 12 is opposite.
After material falls in crushing mechanism by discharge port 10, driving mechanism drives 12 turns of the first breaker roll 11 and the second breaker roll
Dynamic, the first breaker roll 11 and the second breaker roll 12 are mutually twisted, just broken to carry out to material.
It is equipped with partition 13 in the broken case 2, broken 2 inner cavity of case is divided into left crusher chamber and the right side to be crushed by the partition 13
Chamber.The right crusher chamber is located at below the crushing mechanism.Pass through filter screen 14 between 2 one side wall of the partition 13 and broken case
Connection, the filter screen 14 are obliquely installed, and between the crushing mechanism and right crusher chamber.
Material is completed on crushing mechanism after being just crushed, and is fallen on filter screen 14 by self weight.The biggish material of partial size is along mistake
Strainer 14 moves, and falls in left chamber.The mesh that the lesser material of partial size then penetrates filter screen 14 is fallen in right chamber.
Support plate 15 is additionally provided in the broken case 2, the upright bar 8 is rotatably connected in support plate 15.The support plate
The first belt pulley 16, the second belt pulley 17 and third belt pulley 18 are also equipped on 15.First belt pulley 16 is sleeved on vertical
8 periphery of bar, first belt pulley 16, the second belt pulley 17 and third belt pulley 18 pass sequentially through belt transmission connection.
In rotation, first bevel gear 6 and second bevel gear 7 are intermeshed the shaft of motor 5, so that upright bar 8 turns therewith
It is dynamic.Since the first belt pulley 16 is sleeved on 8 periphery of upright bar, the first belt pulley 16, the second belt pulley 17 and third belt pulley 18 are logical
Belt transmission connection is crossed, upright bar 8 drives the second belt pulley 17 and third belt pulley 18 to rotate in rotation.
Left crushing rod 19 and right crushing rod 20 are set on second belt pulley 17 and third belt pulley 18.It is described left broken
Broken bar 19 and right crushing rod 20 are located in left crusher chamber and right crusher chamber.19 periphery of left crushing rod is set with left broken
Blade 21, right 20 periphery of crushing rod are set with right broken blade 22.
Length, quantity, the density of the left broken blade 21 are all larger than the length of the right broken blade 22, quantity, close
Degree.
Since the material particular diameter fallen in left crusher chamber is larger, above-mentioned design can guarantee left broken blade 21 to material
Crushing effect ensure that fragmentation quality of the broken blade to material of left and right crusher chamber.
Motor 5, which can drive, drives 4 feeding of feeding spiro rod, and left broken blade 21 and right broken blade 22 can be driven right
Material is crushed.Since only with a driving device, it is more reasonable to design, help to reduce manufacturing cost.
When second belt pulley 17 and third belt pulley 18 rotate, left crushing rod 19 and right crushing rod 20 are rotated with it.And it is left
Broken blade 21 and right broken blade 22 are mounted on left crushing rod 19 and right crushing rod 20, left broken blade 21 and right broken leaf
Piece 22 carries out second-time breakage to the material in left crusher chamber and right crusher chamber respectively.
Left strainer 23 and right strainer 24, the left strainer 23 and the right side are connected separately in the left crusher chamber and right crusher chamber
Left crusher chamber and right crusher chamber are connected to by strainer 24 with external environment respectively.
Material after second-time breakage passes through left strainer 23 and right strainer 24 respectively and is fallen by broken case 2.
Transmission device is equipped with below the broken case 2.The transmission device includes but is not limited to conveyer belt 25, broken
After material is by left strainer 23 and right strainer 24, fallen on conveyer belt 25 by self weight.
Discharge bucket 26 is equipped with below the broken case 2, the left strainer 23 is connected to crusher chamber and discharge bucket with right strainer 24
26.The discharge port of the discharge bucket 26 is close to the conveyer belt 25.From top to bottom, the horizontal sectional area of the discharge bucket 26 is gradually
Reduce.
After material is fallen by broken case 2, it can more be smoothly through discharge bucket 26 and fall on conveyer belt 25, and slow down
Fall behind material to impact force caused by conveyer belt 26.Specifically, the discharge bucket 26 is funnel-shaped, from top to bottom, the discharging
The horizontal sectional area of bucket 26 gradually decreases.
Due to the funnel-form with a narrow upper and lower width of discharge bucket 26, material is not easy to be bonded in discharge bucket 26, discharges more smooth.
In above scheme, the left crushing rod 19 and 20 one end of right crushing rod are connected on box for feeding odd 3, and by box for feeding odd 3
Support.
To sum up, Nd-Fe-B permanent magnet waste residue crushing device proposed by the present invention can repeatedly be crushed material, break
Broken high-efficient, crushing effect is stablized, and ingenious in design, and manufacturing cost is low.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
