Abstract

The invention relates to an airflow type revolving screen belonging to the technical field of screening equipment structures. The airflow type revolving screen is characterized by comprising a revolving cavity body; the upper part of the revolving cavity body is provided with an air exhaust opening and the lower part of the revolving cavity body is provided with a qualified product outlet; a revolving blade installed on a revolving shaft and a screen mesh covered outside the revolving blade are arranged in the revolving body; one end of the revolving shaft is connected with a hollow shaft of a compressed air joint; the revolving shaft is axially provided with an overflowing through hole leading to an external revolving blade; and the revolving blade is provided with air injection holes dead against an external screen mesh. The airflow type revolving screen has a reasonable structural design and is time-saving and labor-saving in operation. With the adoption of the airflow type revolving screen, the effective screening area of the screen mesh is effectively increased, the screening efficiency is fully improved, the service life of the screen mesh is also prolonged at the same time, the waste time for replacing and processing the screen mesh is reduced, the work efficiency is improved, the loss is reduced, and heat generated by friction between the blade of the revolving screen and powder can be reduced by introduced compressed air so as to improve the looseness of the powder and improve the quality of a product.

Description

The air-flowing type rotary screen
 
Technical field
The present invention relates to efficient, the meticulous screening plant of a kind of powdery paints, particularly a kind of air-flowing type rotary screen belongs to the screening plant technical field of structures.
Background technology
Since the powdery paints suitability for industrialized production, the following form of the general employing of its screening plant: rotary screen generally uses on the continuity production equipment, and what use on the rotary screen generally is nylon screen, and the order number is between 140 order to 200 orders.Operation principle is: produce centrifugal force through center blade rotating band animal material, under action of centrifugal force, the material particle passes screen cloth, deposits to the rotary screen meal outlet.That does not pass screen cloth is rotated to the other end meal outlet of screen cloth than coarse granule, gets rid of.
Powdery paints consist of resin and filler, the average grain diameter after the fragmentation is between the 32um-38um, the particle between this is static electrification very easily, and certain viscoplasticity is arranged between particle.
Because the powdery paints particle is static electrification very easily, and certain viscoplasticity is arranged between particle, so very easily attached on the nylon screen, the time one produces following problem for a long time: 1, screening efficiency seriously descends, and has only 30% of new screen cloth when minimum.2, the product average grain diameter after the screening diminishes, and influences the product serviceability.3, the sieve breakage rate increases.
Summary of the invention
The objective of the invention is to solve the weak point that above-mentioned prior art exists, a kind of reasonable in design is provided, cost is low and can improve screening efficiency, guarantee the product serviceability, reduce the air-flowing type rotary screen of sieve breakage rate.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The air-flowing type rotary screen; Special character is to comprise that top has exhaust outlet C, the bottom has the rotation cavity A that qualified products export B; Said rotation cavity A inside is provided with the screen cloth 3 of revolving vane 2 that is installed on the rotating shaft 1 and the outside that covers at revolving vane 2; Said rotating shaft 1 is the hollow shaft that an end is connected with Compressed Gas joint 4; What axially the offering of rotating shaft 1 led to outside revolving vane 2 crosses opening 1-1, and revolving vane 2 faces outer screen 3 places and is uniformly distributed with and offers fumarole 2-1, and Compressed Gas is sent to the axle inner chamber of rotating shaft 1 through Compressed Gas joint 4; The opening 1-1 that crosses through on the rotating shaft 1 is sent to revolving vane 2 places; Blow to outermost screen cloth 3 through fumarole 2-1 set on the revolving vane 2 at last, under the effect of air-flow, get into rotary screen cavity A inside, drop down onto the qualified products outlet at last and discharge thereby make attached to the subparticle on the screen cloth 3; Getting into rotation cavity A gas inside then discharges through the exhaust outlet C on its top.
Said Compressed Gas is through the cooled Compressed Gas of cooling device;
The exhaust outlet C on said rotation cavity A top is connected with dust cleaning case.
Air-flowing type rotary screen of the present invention, reasonable in design, it is time saving and energy saving to operate; Effectively improve the effective sifting area of screen cloth, fully improved screening efficiency, improved the life-span that screen cloth uses simultaneously; Reduced because of changing and handled the time that screen cloth is wasted, improved operating efficiency, reduced loss; The Compressed Gas that feeds can reduce the heat that the rotary screen blade produces with the powder friction, thereby has increased the laxity of powder, the quality of raising product.

The specific embodiment
Following with reference to accompanying drawing, provide the specific embodiment of the present invention, be used for formation of the present invention is further specified.
Embodiment 1
The air-flowing type rotary screen of present embodiment is with reference to figure 1,2; Comprise that top has exhaust outlet C, the bottom has the rotation cavity A that qualified products export B; Said rotation cavity A inside is provided with the screen cloth 3 of revolving vane 2 that is installed on the rotating shaft 1 and the outside that covers at revolving vane 2; Said rotating shaft 1 is the hollow shaft that an end is connected with Compressed Gas joint 4; What axially the offering of rotating shaft 1 led to outside revolving vane 2 crosses opening 1-1, and revolving vane 2 faces outer screen 3 places and is uniformly distributed with and offers fumarole 2-1.Said Compressed Gas is through the cooled Compressed Gas of cooling device; The exhaust outlet C on said rotation cavity A top is connected with dust cleaning case.
When the present invention works; The Compressed Gas joint 4 of external compression source of the gas with rotary screen one side is connected; Compressed Gas is sent to the axle inner chamber of rotating shaft 1 immediately, through the chamber interior that opening 1-1 is sent to revolving vane 2 of crossing on the rotating shaft 1, blows to outermost screen cloth 3 through fumarole 2-1 set on the revolving vane 2 at last; Thereby make attached to the subparticle on the screen cloth 3 and under the effect of air-flow, get into rotary screen cavity A inside, drop down onto the qualified products outlet at last and discharge; Getting into rotation cavity A gas inside then discharges through the exhaust outlet C on its top.
Beneficial effect of the present invention:
1, because ejection gas applies the pressure of certain sensing screen cloth to powder particle, increases the centrifugal force of powder particle, accelerated the speed that powder particle sees through screen cloth, improved screening efficiency.
2, Compressed Gas blows to screen cloth, makes the viscosity subparticle can not stop up mesh, improves the screen cloth effective sifting area, thereby has improved screening efficiency.
3, the screen cloth mesh no longer stops up, and improves screen cloth service life, reduces the wastage, and also reduces owing to change the production man-hour that screen cloth is wasted simultaneously.
4, the compressed air of cooling feeding reduces revolving vane and the fricative heat of powder, and the powder laxity is increased, and improves the quality of products.
The above embodiment of the present invention only be for clearly the present invention is described and is done for example; And be not to be the qualification to embodiment of the present invention; Those of ordinary skill for affiliated field; On the basis of above-mentioned explanation, can also make other multi-form variation or change, can't give exhaustively here, everyly belong to the row that conspicuous variation that technical scheme of the present invention extends out or change still are in protection scope of the present invention all embodiments.
