Abstract
The invention relates to a material screening and subpackage device, in particular to a closed neodymium iron boron permanent magnet material screening and subpackage device. The device is characterized in that powder enters a screening machine through a feed tank and is fully screened in the screening machine; the powder with different particle sizes is separated; and the qualified powder is screened by a vibrating screening machine and then enters a discharge tank. Structures of various parts are in sealing connection, so that the screening and subpackage integrated sealability of a neodymium iron boron permanent magnet material is ensured; the quality and the production efficiency of products are improved; the production operation is simplified; and a production safety factor is increased obviously.
Description
Technical field
The present invention relates to a kind of material screening dispenser, especially a kind of closed Nd-Fe-Bo permanent magnet material screening dispenser.
Background technology
The powder after mixing is needed to sieve in Nd-Fe-Bo permanent magnet material manufacture process, the powder being about to wherein impurity and particle large sieves out, and by qualified powder tank filling, its sieve material process need completes through multiple step, to treat that sieve powder is released from tank body, a general tank powder needs 25 sealing bags, then by the powder of these 25 sealing bags successively to entering in vibratory sieve to sieve, after screening, reinstall in new sealing bag.First original technology is loaded down with trivial details, and program is too much.Secondly the Nd Fe B alloys powder chance oxygen in sealing bag is inflammable brings very large potential safety hazard to production.In addition, although packing sieve after material time use nitrogen protection, can not accomplish the environment of complete anaerobic, can there is oxidation reaction in powder after contacting with oxygen, causes the properties of product of later stage production and processing to decline to some extent.
Summary of the invention
In sum, in order to overcome the deficiencies in the prior art, the invention provides a kind of closed Nd-Fe-Bo permanent magnet material screening dispenser, realize screening and the packing integration of Nd-Fe-Bo permanent magnet material, operating efficiency increases substantially, simplify production operation, reduce labour personnel and labour intensity, reduce the usage quantity of sealing bag, economize on resources, and tank ensure that the closure of screening point process of assembling to the docking under tank oxygen-free environment, except ensureing the quality of production of product, Nd Fe B alloys powder and oxygen-barrier can also be made, get rid of the potential safety hazard of combustion explosion, significantly improve the safety coefficient of production, secure to the safety of producers.After the research and development of close screen material caging machine, powder operates in oxygen-free environment, and easily oxidized Nd Fe B alloys powder almost non-oxidation, increases substantially quality and the quality of product.
The present invention solve that its technical problem adopts technical scheme be: the reciprocating rotary type vibration utilizing oscillator exciting to produce and work, the upper rotation weight of oscillator makes compass screen surface produce plane whirling vibration, lower rotation weight then makes compass screen surface produce conical surface rotary vibration, its symphyogenetic effect makes compass screen surface generation revolve type vibration again, thus the powder of variable grain size is screened out from different discharging opening.Wherein discharge tank is vertically positioned over the top of vibrating screen classifier by batch can fixed mount; the discharging opening of discharge tank is connected with the material receiving port of vibrating screen classifier; the upside of close screen material caging machine is provided with into protection gas port, oxygen outlet and rotary unloading control valve; coarse fodder outlet and powder outlet is provided with on the downside of screening machine; discharge tank is connected with body by powder outlet; material screening machine side is provided with control oxygen instrument interface, also has cleanout to prevent powder to be scattered on the downside of body.
Described discharge tank is vertically positioned over the top of vibrating screen classifier by batch can fixed mount, and the discharging opening of discharge tank is connected with the material receiving port of vibrating screen classifier.
The upside of described close screen material caging machine is provided with into protection gas port, oxygen outlet and Multi-stage rotary blanking control valve, is provided with coarse fodder outlet and powder outlet on the downside of screening machine, and material screening machine side is provided with control oxygen instrument interface, also has cleanout on the downside of body.
Described discharge tank is connected with body by powder outlet.
Described head tank, batch can fixed mount, vibrating screen classifier, is connected and sealed by screw thread, Push-fit, the sealing of glue ring, ring flange locking etc. or other modes between discharge tank.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the present invention is further described.
Fig. 1 is the perspective view of closed Nd-Fe-Bo permanent magnet material screening dispenser most preferred embodiment of the present invention;
Fig. 2 is closed Nd-Fe-Bo permanent magnet material screening dispenser internal cross section figure of the present invention.
In figure: 1, discharge tank, 2, oxygen outlet, 3, rotary unloading control valve 4, vibrating screen classifier, 5, coarse fodder outlet; 6, KY-2F type control oxygen instrument is connect, 7, cleanout, 8, splice jug, 9, powder outlet; 10, powder funnel, 11, enter to protect gas port, 12, material tube fixing device.
Detailed description of the invention
Embodiment 1
Prepare one with wait to sieve the equal holding vessel of powder tank volume, pour nitrogen by the air emptying in tank.
Open the oxygen outlet of close screen material caging machine, nitrogen is injected caging machine by the import of protection gas, the air in close screen material caging machine is all discharged only.When oxygen content pointer floats between 0-30 in control oxygen instrument, will treat that sieve tank body is connected with close screen material caging machine.
Opening vibrating screen classifier, powder outlet successively, treat sieve batch can tank mouth, waiting to sieve the speed that powder enters vibratory sieve by regulating rotary unloading control valve to regulate.
Note the amplitude of control oxygen instrument pointer, be safe range at 0-30, the speed that nitrogen injects when being greater than 30, should be strengthened, reduce and wait to sieve the speed that powder enters vibratory sieve.
After powder has all sieved, stop vibrating screen classifier, after powder natural subsidence in machine, first closed the tank mouth of splice jug, splice jug is separated placement with close screen material caging machine.
Waiting before removing sieves powder tank, closes nitrogen mouth, is collected by powder remaining in close screen material caging machine by cleanout.
Be noted that above-described embodiment is unrestricted to the explanation of technical solution of the present invention, art technical staff is equal to other amendments replaced or make according to prior art, as long as do not exceed thinking and the scope of technical solution of the present invention, within the interest field that all should be included in application claims.
