Background technology
Since the large-scale continuous suitability for industrialized production of powdery paints, grinder system is one of emphasis key equipment in the middle of powdery paints is produced always, and its continuous, the efficient production capacity extremely producer's green grass or young crops is narrowed.What in grinding powder paint system, generally adopt at present, is single cyclone separator structure or cyclone cyclone separator arrangement.The separative efficiency of single cyclone separator structure is always not high, causes in powder coating product and contains a large amount of superfine powders always, directly affects quality and the utilization rate of powder-product electrostatic spraying; Although cyclone cyclone separator arrangement changes the content of superfine powder in powdery paints to a great extent, in production process, the recovery rate of product obviously reduces, and loss increases.
Summary of the invention
By research and practice for many years, we change the connected mode of double separator structure, adopt round-robin method, the superfine powder of second segment output is back in first paragraph separator again, allow superfine powder constantly in two separators, circulate, ceaselessly separated, until the qualified particle diameter powder in superfine powder isolated completely, to improve product recovery rate and output.
The utility model aims to provide a kind of by changing the connected mode of cyclone separator, so reach the output that improves grinding system with separated precision, reduce energy consumption, meet the novel high-efficiency and energy-saving grinder system of more customer demands.
The utility model is achieved through the following technical solutions:
Novel high-efficiency and energy-saving grinder system, comprise the primary cyclone 3 that grinds main frame 1, is connected with grinding main frame 1 by pipeline, and the secondary cyclone 4 being connected with described primary cyclone 3 by connecting pipe 12, the top of wherein said primary cyclone 3 by pipeline connection to by the disposal box 5 of air-introduced machine 6 control connections; Special character is, between described primary cyclone 3 bottoms and described connecting pipe 12, be provided with first row materials device 8, the lower end of described secondary cyclone 4 is connected with second row materials device 9, and the top of described secondary cyclone 4 is communicated to described primary cyclone 3 by reflux cycle pipeline 7.
Described primary cyclone 3 is that two branch roads by Y-piece road 2 are connected with described grinding main frame 1 and reflux cycle pipeline 7 respectively.
Between the bottom of described first row materials device 8 and described connecting pipe 12, one-level rotary screen 10 is installed.
The bottom of described second row materials device 9 is provided with secondary rotary screen 11.
Described first row materials device 8, second row materials device 9 can adopt the material discharging machine of air valve door or powder industry universal.
The utility model novel high-efficiency and energy-saving grinder system, by changing the reflux cycle of secondary cyclone, obtains two separated particle diameter distribution effects, and the higher productive rate of getting back, plays energy-efficient effect.

The specific embodiment
Referring to accompanying drawing, provide the specific embodiment of the present utility model, be used for structure of the present utility model to be further described.
Embodiment 1
Novel high-efficiency and energy-saving grinder system reference Fig. 1-2 of the present embodiment, comprise the primary cyclone 3 that grinds main frame 1, is connected with grinding main frame 1 by pipeline, and the secondary cyclone 4 being connected with described primary cyclone 3 by connecting pipe 12, the top of wherein said primary cyclone 3 by pipeline connection to by the disposal box 5 of air-introduced machine 6 control connections; Described primary cyclone 3 bottoms are communicated with the first material discharging machine 8 and one-level rotary screen 10 successively, and described one-level rotary screen 10 is connected with connecting pipe 12.The lower end of described secondary cyclone 4 is connected with the second material discharging machine 9, and described the second material discharging machine 9 bottoms are connected with secondary rotary screen 11; The top of described secondary cyclone 4 is communicated to described primary cyclone 3 by reflux cycle pipeline 7.Described primary cyclone 3 is that two branch roads by Y-piece road 2 are connected with described grinding main frame 1 and reflux cycle pipeline 7 respectively.
The course of work of the present embodiment is as follows:
Through grinding the powder of main frame 1 pulverizing, enter in primary cyclone 3, more than 98% powder of qualified particle diameter is wherein under the effect of centrifugal force, the separated bottom that is deposited to primary cyclone 3, through the first material discharging machine 8, enter one-level rotary screen 10, superfine powder is taken away by primary cyclone 3, enters disposal box 5.
After entering powder in one-level rotary screen 10 and being sized, by connecting pipe 12, enter in secondary cyclone 4, the bottom that is deposited to secondary cyclone 4 by the isolated qualified powder of secondary cyclone 4, enters in secondary rotary screen 11 through the second material discharging machine 9, is sieved into finished product vanning.And the Y-piece road 2 that the qualified powder of the superfine powder of being taken away by secondary cyclone 4 and part installs additional before by reflux cycle pipeline 7 and primary cyclone 3 reenters in primary cyclone 3, so circulation later.
Owing to being back in primary cyclone 3 at the isolated powder of secondary cyclone 4, form circulation separated, so the separating effect of novel high-efficiency and energy-saving grinder system is fabulous, productive rate obviously improves.
