Abstract
The invention relates to a duplex-cyclone powder recovery system. The system is characterized by comprising a first stage cyclone separator, a second stage cyclone separator and a recycling fan, wherein an air inlet of the first stage cyclone separator is connected with a powder spray chamber, an air outlet of the first stage cyclone separator is connected with an air inlet of the second stage cyclone separator by an air pipe, and an air outlet of the second stage cyclone separator is connected with the recycling fan by another air pipe. The duplex-cyclone powder recovery system is simple in structure and reasonable in design, is thoroughly free of the problem of blockage, and enables the wind pressure and flow of the recycling fan to be balanced and constant.
Description
Technical field
The present invention relates to specifically a kind of cyclone powder recovery system of powder coating recovery technology.
Background technology
In powder coating process, powder needs to reclaim in time.Current powder coating reclaims the technology generally used mainly to be had following several: (1), single-stage sieve core callback；(2) cyclone separator+sieve core callback；(3) cyclone separator+filter element+sintered plate reclaims.But above-mentioned several powder coating recovery technologies all exist the problem of recovery system blocking, system jams influences whether to reclaim blast and the flow of blower fan, and then has influence on product coating quality.It addition, in powder coating process, powder is to be mixed by a certain percentage by the plastic pellet that granular size is different, existing Powder Recovery technology is all unified recovery, powder after recovery is mixing after new powder, and the bad control of powder particle ratio affects powder properties and coating quality.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of cyclone powder recovery system, its simple in construction, reasonable in design, it is possible to the problem thoroughly solving powder recovery system blocking, it is ensured that the blast of recovery blower fan and the equilibrium of flow are constant.
The technical scheme provided according to the present invention: cyclone powder recovery system, it is characterized in that: include primary cyclone, secondary cyclone and recovery blower fan, the air inlet of described primary cyclone is used for connecting powder spraying chamber, the air outlet of primary cyclone is connected with the air inlet of secondary cyclone by airduct, and the air outlet of described secondary cyclone connects back to, by airduct, the machine of calling prisoners in after letting them out for exercise.
As a further improvement on the present invention, the cyclone separator being suitable for reclaiming the powder particle of more than 5 μm selected by described primary cyclone, and described secondary cyclone is selected and is suitable for reclaiming 5 μm and the cyclone separator of following powder particle.
As a further improvement on the present invention, high pressure positive blower selected by described recovery blower fan.
The present invention compared with prior art, has the advantage that
1), present configuration simple, reasonable in design, it is possible to the problem thoroughly solving powder recovery system blocking, it is ensured that the equilibrium reclaiming the blast of blower fan and flow is constant.
2) over-spray powder in, the present invention ensure that powder spraying chamber is the most excessive.
3), the present invention can be sufficiently separated meticulous powder particle, it is ensured that mixes the powder particle ratio after new powder, it is ensured that powder properties.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the cyclone powder recovery system in embodiment is mainly made up of primary cyclone 2, secondary cyclone 3 and recovery blower fan 4, the air inlet of described primary cyclone 2 is used for connecting powder spraying chamber 1, the air outlet of primary cyclone 2 is connected with the air inlet of secondary cyclone 3 by airduct, and the air outlet of described secondary cyclone 3 connects back to the machine of calling prisoners in after letting them out for exercise 4 by airduct.
In the present embodiment, the cyclone separator being suitable for reclaiming the powder particle of more than 5 μm selected by described primary cyclone 2, and described secondary cyclone 3 is selected and is suitable for reclaiming 5 μm and the cyclone separator of following powder particle.
The operation principle of the present invention is as follows:
During work, reclaim blower fan 4 start and produce negative pressure, in powder spraying chamber 1, the powder of overspray enters primary cyclone 2 with certain initial velocity under suction function, and internal cyclone tube wall along primary cyclone 2 does downward screw under the influence of centrifugal force, the powder of bulky grain [more than 5 μm] naturally falls in the collection powder drum of primary cyclone 2, and the powder of granule less [5 μm and following] can move upward along the axis of primary cyclone 2, discharge from the air outlet of primary cyclone 2, secondary cyclone 3 is entered the most again with certain initial velocity, and caught collection by secondary cyclone 3.
Claims (3)
