Abstract
The utility model relates to an air-flowing type rotary screen, which belongs to the technical field of a screening equipment structure. The air-flowing type rotary screen is characterized by comprising a rotary cavity with an air outlet on the upper part and a qualified product outlet on the lower part, rotary vanes arranged on a rotary shaft and a screen mesh covering the rotary vanes are arranged in the rotary cavity, the rotary shaft is a hollow shaft of which one end is connected with a compressed gas connector, the rotary shaft is axially provided with a flow passing through hole leading to the external rotary vanes, and gas orifices are uniformly distributed in the positions of the rotary vanes, which is over against the external screen mesh. According to the air-flowing type rotary screen disclosed by the utility model, the working efficiency is improved, loss is reduced, and the introduced compressed gas can be used for reducing heat produced by the friction of the rotary vanes and powder, so that the looseness of the powder is improved, and the quality of products is improved.
Description
Technical field
The utility model relates to that a kind of powdery paints is efficient, the fine sieve subset, and 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 at consecutive 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: rotarily drive material by the center blade and produce centrifugal force, under the effect 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 be attached on the nylon screen, the time one produces following problem for a long time: 1, screening efficiency degradation, only have 30% of new screen cloth when minimum.2, the product average grain diameter after the screening diminishes, and affects the product serviceability.3, the sieve breakage rate increases.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and provides a kind of reasonable in design, cost is low and can improve screening efficiency, guarantee the product serviceability, reduce the air-flowing type rotary screen of sieve breakage rate.
For achieving the above object, the utility model adopts following technical scheme:
The air-flowing type rotary screen, special character is to comprise that top is with exhaust outlet C, the bottom is with the rotation cavity A of qualified products outlet B, described rotation cavity A inside is provided with the screen cloth 3 of the revolving vane 2 that is installed on the rotating shaft 1 and the outside that covers at revolving vane 2, described 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, revolving vane 2 faces the uniform fumarole 2-1 that offers in outer screen 3 places, Compressed Gas is sent to the axle inner chamber of rotating shaft 1 by Compressed Gas joint 4, be sent to revolving vane 2 places by the opening 1-1 that crosses on the rotating shaft 1, blow to outermost screen cloth 3 by fumarole 2-1 set on the revolving vane 2 at last, thereby it is inner to make the subparticle that is attached on the screen cloth 3 enter rotary screen cavity A under the effect of air-flow, drops down onto at last the qualified products outlet and discharges; The gas that enters rotation cavity A inside is then discharged by the exhaust outlet C on its top.
Described Compressed Gas is through the cooled Compressed Gas of cooling device;
The exhaust outlet C on described rotation cavity A top is connected with dust cleaning case.
The utility model air-flowing type rotary screen, reasonable in design operates time saving and energy saving, the effective sifting area of Effective Raise screen cloth, fully improved screening efficiency, improve simultaneously the life-span that screen cloth uses, reduced because changing and processed the time that screen cloth is wasted, improved operating efficiency, reduced loss, the Compressed Gas that passes into can reduce rotary screen blade and powder friction and the heat that produces, thereby has increased the laxity of powder, improves the quality of product.

The specific embodiment
Referring to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.
Embodiment 1
The air-flowing type rotary screen of the present embodiment is with reference to figure 1,2, comprise that top exports the rotation cavity A of B with qualified products with exhaust outlet C, bottom, described rotation cavity A inside is provided with the screen cloth 3 of the revolving vane 2 that is installed on the rotating shaft 1 and the outside that covers at revolving vane 2, described 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 the uniform fumarole 2-1 that offers in outer screen 3 places.Described Compressed Gas is through the cooled Compressed Gas of cooling device; The exhaust outlet C on described rotation cavity A top is connected with dust cleaning case.
During the utility model work, 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, by the chamber interior that opening 1-1 is sent to revolving vane 2 of crossing on the rotating shaft 1, blow to outermost screen cloth 3 by fumarole 2-1 set on the revolving vane 2 at last, thereby it is inner to make the subparticle that is attached on the screen cloth 3 enter rotary screen cavity A under the effect of air-flow, drops down onto at last the qualified products outlet and discharges; The gas that enters rotation cavity A inside is then discharged by the exhaust outlet C on its top.
The beneficial effects of the utility model:
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 changing the production hour that screen cloth is wasted simultaneously.
4, cool off the compressed air that passes into, reduce revolving vane and the fricative heat of powder, the powder laxity is increased, improve the quality of products.
Above-described embodiment of the present utility model only is for the utility model example clearly is described; and be not to be restriction to embodiment of the present utility model; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here can't give all embodiments exhaustively, everyly belong to the row that apparent variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
