The leaked powder cleaning device solves the problem that clumps can be generated to cause jam when metal powder with a certain of humidity enters a drying furnace hopper. The leaked powder cleaning device comprises a support, a driving device, a conical feed hopper and a lifting rotating device, wherein the driving device is installed at the upper part of the support, and the lifting rotating device is installed between the support and the feed hopper. The lifting rotating device is provided with at least two screw rods, and each screw rod is connected with an autorotation power device fixed on a cross beam frame. The screw rods are arranged along the conical surface in the feed hopper, and gaps are arranged between the screw rods and the conical surface. The lifting rotating device moves up and down by the driving device and a lifting mechanism, and the moving position is regulated according to the powder flow in the feed hopper. More than two screw rods autorotate in the hopper, and screw teeth have large friction extrusion capability. As the lower ends of the screw rods can be extended into the lower neck of the feed hopper, the metal powder clumps can be completely shattered.
Description
Technical field
The utility model relates to powder metallurgy production equipment technical field, relates in particular to a kind of leakage powder cleaning plant of clearing up powder agglomerate in the broach hopper.
Background technology
In the powder metallurgy flour production line, atomized powder through dehydration after, be transported to drying oven, in course of conveying, gather agglomeratingly easily, these lumps powder especially stop up in broach hopper easily.Though the cleaning plant in the conveyer belt is various informative, be structural design mostly according to material of being carried and distinct device input and output material.As the patent No. is the scraper-type cleaning plant that one kind of ZL200820013888.2 is used for the conveyer band; As number of patent application is 00110979.0 1 kinds of devices that are applied to the cleaning of converter dry slag, constitute by scarfing cinder hydraulic cylinder, scarfing cinder head and supporting and adjusting device, by adjusting supporting and adjusting device, can make the active force of scarfing cinder head act directly on the junction of slag and fire door, it can be applicable to the cleaning of various planes dry slag.The patent No. is the cleaning plant of ZL200420068965.6 solid material fragmentation for another example, the cleaning plant of feeding mouth during material sample that particularly the crusher in crushing moisture is higher or viscosity is bigger, and these structures are with of the present invention all different.
Summary of the invention
The purpose of this utility model is that the generation agglomerate causes blocking problem when the metal dust with certain humidity enters the drying oven hopper in order to solve, a kind of reasonable in design is provided, utilize to have the screw rod that revolves tooth more than two and circle round, dredge the leakage powder cleaning plant of the powder agglomerate in the hopper fast along the funnel direction.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of leakage powder cleaning plant, comprise drive unit, the bullet of support, rack-mount portion feed hopper, be installed in the lift rotating equipment between support and the feed hopper, it is characterized in that described lift rotating equipment be provided with cross beam frame, on be no less than two screw rods, every screw rod connects with autorotation power apparatus on being fixed on cross beam frame, and screw rod is arranged and is provided with the space with taper surface along the taper surface in the feed hopper.Lift rotating equipment moves up and down by drive unit and elevating mechanism, according to the position up and down of the powder Flow-rate adjustment in the feed hopper, screw rod more than two is done rotation in hopper, revolve tooth and have bigger frictional force and extrusion capability, because the lower end of screw rod can reach the end opening neck place of feed hopper, so the metal dust agglomerate can be fragmentary fully.
As preferably, described screw rod is provided with the spiral gear piece.Spiral gear piece rotation direction on some screw rods is opposite, and rotating speed can be set separately.
As preferably, the taper surface in the lower end edge feed hopper of described screw rod extends the following outlet of bullet, and keeps the space.Under the effect of elevating mechanism, screw rod moves up and down.
As preferably, the angle of described screw rod and feed hopper center line is less than the angle of feed hopper taper surface and feed hopper center line.Screw rod can not be run into feed hopper, the spiral gear piece contacts with powder fully, some screw rods all point to the outlet of feed hopper, the direction of rotation of spiral gear piece can be set at the upwards direction of operation of powder, when running into bigger powder ball like this, screw rod be not directly powder ball to the outlet of feed hopper extruding, but powder ball is upwards enlivened fragmentary, flow out feed hopper by the powder deadweight again.
As preferably, be provided with elevating mechanism between described drive unit and the lift rotating equipment, elevating mechanism is connected with cross beam frame.Elevating mechanism adopts modes such as screw or wireline pulley, and cross beam frame and support are fixed.
Effective effect of the present invention is: the powder that has certain moisture content after atomized powder is through dehydration is transported in the process of drying oven, and it is agglomerating to have prevented that thoroughly metal dust from gathering, and provides good basis smoothly for subsequent processing.
Therefore, the utility model is a kind of reasonable in design, and is applied widely, economically viable leakage powder cleaning plant.
