Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, a kind of powder collecting vessel, including outer cylinder, it is arranged in outer cylinder and is formed in sandwich with outer cylinder
Cylinder.Inner barrel and outer barrel is prepared using stainless steel material.
The top opening of outer cylinder, is closed by cover board, and cover board is connect by ring flange with outer cylinder, is sealed with O-ring.
The side of outer cylinder is welded with the feed pipe extended in outer cylinder, and feed pipe is connected to by feeding pipe connector with inner cylinder, feed pipe
Connector can be to be flexible coupling (hose adds anchor ear) or Hard link (clip).The outer cylinder other side is welded with discharge pipe.Outer cylinder goes out
Material mouth is connected to powder collecting tank, is slid for convenience of powder particle into powder collecting tank, discharge port uses vertebral body structure, centrum knot
Structure is connect by ring flange with outer cylinder, is sealed by O-ring.
Setting is connected with vacuum elements between outer cylinder discharge port and powder collecting tank, and vacuum elements include passing through clip successively
Level-one Hygiene Ball Valve, the first exhaust tube, second level Hygiene Ball Valve, the second exhaust tube being connected and fixed, it is close with silicagel pad between clip
Envelope.First exhaust tube and the second exhaust tube have the small ball of trachea, and discharge port is connect with level-one Hygiene Ball Valve, and powder is collected
Tank is connect with the second exhaust tube.
Motor cabinet and adjustable speed motor are provided with above outer cylinder, motor cabinet, which is fixed by screws in, to be collected on cover plate,
Motor is fixed by screws on motor cabinet.
As shown in Fig. 2, inner cylinder is tertiary structure, upper straight tube, centrum and lower straighttube including successively welded seal, inner cylinder is logical
It crosses interior tube stent and is arranged in outer cylinder, fixation is bolted.Upper straight tube inner top position is provided with blade group, blade group
For multilevel structure, including at least two grade blades, the series of blade can be adjusted as needed.The type of blade can be axis stream
One of formula, centrifugal, mixed-flow, vortex.As shown in figure 3, second level leaf may be selected in blade group using axial--flow blading
Piece, inferior clearance dislocation installation on the flabellum in two grade blades, a grade blade are located at two grade blades top, and the fan of a grade blade
Leaf diameter is greater than the flabellum diameter of two grade blades.One grade blade mainly generates downward spiral thrust, and two grade blades mainly generate
Eddy airstream.
Motor power output end is provided with sealing element, and shaft one end in sealing element is connect with motor drive, and the other end is worn
It crosses collection cover plate and stretches to inner cylinder, be fixedly connected with blade group, such sealing element is same by the power transmission of motor to inner cylinder
When outer cylinder is sealed, magnetic fluid seal can be used in sealing element.If dust collection bucket is it is not necessary that when sealing, sealing element can be used instead
Thrust bearing.As shown in figure 4, being provided with upper bolt hole and lower bolt hole in the vertical direction of blade axle sleeve, upper bolt hole is under
Bolt hole runs through axle sleeve in the horizontal direction, and corresponding bolt hole is provided in the shaft of sealing element, by bolt by blade and
Sealing element is fixedly connected, and guarantees that blade center is overlapped with the center of gravity of sealing element.
When motor works, inner cylinder provides fixed boundary condition to the air-flow that blade generates, and plays the role of duct, passes through
The dimensional parameters of inner cylinder are adjusted, can control the granularity of dust collected and quality.If a is the upper straight tube height of inner cylinder, b is inner cylinder
Upper straight tube diameter, c are the cone height of inner cylinder, and d is the diameter of inner cylinder lower straighttube, and e is inner cylinder lower straighttube height.The value of a is bigger,
Collision probability is bigger between dust, and the time of coarse powder centrifugation is bigger, is conducive to collect bulky grain;The value of d is smaller, and the value of c gets over senior general
The collision for reducing aggregate and barrel, increases the precision of classification;The value of e gets over senior general and to segment aggregate in eddy airstream tail portion
Residence time is longer, more grows up conducive to aggregate, and then collects the superfine powder of low-density.
The course of work of powder collecting vessel are as follows: driven by the motor, multistage blade high speed rotation is formed inside inner cylinder
Eddy airstream, the inside of inner cylinder are eddy airstream area, and the interlayer between collecting vessel outer cylinder and collecting vessel inner cylinder is quiescent centre, contain powder
Last air-flow enters eddy airstream area, the distance of charging tube hub line a to grade blade by feed pipe under the effect of external circulating fan
Greater than feed tube diameter, but again as close as possible to a grade blade, eddy airstream band that the air-flow containing dust is formed in level-one blade
It is dynamic lower to enter eddy airstream area, and downward spiral is shrunk to the air column of rotation, bulky grain due to the effect of centrifugal force with inner cylinder
Inner wall collision, then fall into collecting tank along inner wall, little particle is moved downward with flow spiral, by adjust motor speed,
The dimensional parameters of blade construction and collecting vessel inner cylinder can choose the grain diameter of collection, and the powder without being collected is gone out
The negative pressure in air port sucks next stage collecting vessel, and in nano level superfine powder, air-flow containing powder enters eddy airstream area, and is formed
Air column is rotated, nano level superfine powder collides in air column, reunites, and air column bottom is contacted with collecting vessel inner cylinder cone discharge port mouth
Afterwards, eddy airstream periphery blocked rotation, aggregate in peripheral air stream with after the collision of collecting vessel inner cylinder inner wall because gravitational settling arrives
In collecting tank, eddy airstream center fine particle is moved along collecting vessel inner cylinder lower straighttube, after collecting vessel inner cylinder lower straighttube, by
Do not constrained by pipeline in air-flow, in downwardly direction gradually radial diffusion, to lose the constraint to powder, will height according to not
Partial size together, current density, the adjustment of powder density, cooperation adjustment air outlet diameter, so that circulating fan was formed in air outlet
Negative pressure is insufficiently resistant to the gravity of powder reuniting body itself, and the powder for losing constraint will be in air outlet quiescent centre below with gravity
Sedimentation, cleaning gas tream will enter quiescent centre at air outlet, return in circulating system from discharge pipe.
When powder is collected, level-one Hygiene Ball Valve and second level Hygiene Ball Valve are first closed, the first exhaust tube and second level are then unclamped
Clip between Hygiene Ball Valve, and second level Hygiene Ball Valve, the second exhaust tube, powder collecting tank are integrally moved into packing case.Installation
When collecting tank, if system needs inert gas or vacuum protection, needs first to extract the air in the first exhaust tube out, then open
Level-one Hygiene Ball Valve and second level Hygiene Ball Valve.The use of powder collecting tank is threadedly coupled, and other component is all using snapping connection, just
Just it dismantles.
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.
