Abstract
The invention relates to an improved rotary screen which comprises a base and a screen box, wherein the base is connected with the screen box through a spring, a feed inlet is formed in the top of the screen box, a side cavity communicated with the feed inlet is a first screening layer, an outlet of the first screening layer is connected with a small particle discharge port, a vertical cavity communicated with the feed inlet is a second screening layer, the second screening layer is connected with a medium particle discharge port, a filter plate is obliquely arranged in a cavity between the second screening layer and the medium particle discharge port, a dryer is arranged in the cavity inside the filter plate, and an outlet of the cavity inside the filter plate is connected with a water discharge port. The invention can selectively screen and has high screening efficiency.
Description
Technical field
The present invention relates to a kind of rotary screen, relate in particular to a kind of improved rotary screen.
Background technology
Rotary screen is made up of base and screen box, and the multilayer screen cloth is arranged in the screen box, and this rotary screen generally is fit to the material of one type of size of screening; Screen cloth is many more, and possibility of jamming is just big more, and is special in the material that contains moisture, sticks to easily in the sieve chamber and on the screen cloth; Cause the screening difficulty big, and contain moisture in the material, after screening finishes, also will add one procedure; Remove the water in the sieve material specially,, increased cost greatly from economic angle.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide the improved rotary screen that a kind of selectivity is sieved, screening efficiency is high.
The technical scheme that the present invention adopts is:
A kind of improved rotary screen comprises base and screen box, and said base is connected with screen box through spring; Said screen box top has charging aperture; The said side cavity that is communicated with charging aperture is the first screening layer, and the said first screening layer outlet is connected with the granule discharging opening, and the said vertical cavity that is communicated with charging aperture is the second screening layer; The said second screening layer is connected with middle particle discharging opening; Cavity tilt between said second screening layer and the middle particle discharging opening has filter, is provided with baker in the cavity of said filter inboard, and the inboard cavity outlet of said filter is connected with discharge outlet.
The inclination angle of said filter and horizontal plane is α, and this angle is 10 °≤α＜60 °.
Said first sieve is layered as the dividing plate that evenly is provided with aperture.
Said second sieve is layered as the sieve plate that is provided with mesopore.
Said second sieve is layered as along the sieve plate of cavity automatic lifting.
Advantage of the present invention is: the first screening layer can come out the material screening less than aperture, and the second screening layer can come out the material screening of medium grain, and the second screening layer can rise along cavity; The large granular materials that is trapped on the second screening layer is ejected; The drying materials that baker can filter along filter, moisture comes out from discharge outlet, removes moisture; Material is difficult for stopping up the screening layer, and screening efficiency improves.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Wherein: 1, base, 2, screen box, 3, spring, 4, charging aperture, 5, aperture, 6, dividing plate, 7, the granule discharging opening, 8, mesopore, 9, sieve plate, 10, middle particle discharging opening, 11, filter, 12, baker, 13, discharge outlet.
The specific embodiment
As shown in Figure 1, a kind of improved rotary screen of the present invention comprises base 1 and screen box 2; Base 1 is connected with screen box 2 through spring 3, and screen box 2 tops have charging aperture 4, and the side cavity that is communicated with charging aperture 4 is the first screening layer; First sieve is layered as dividing plate 6, the first screening layer outlet that evenly are provided with aperture 5 and is connected with granule discharging opening 7, and the vertical cavity that is communicated with charging aperture 4 is the second screening layer; Second sieve is layered as sieve plate 9, the second screening layers that are provided with mesopore 8 and is connected with middle particle discharging opening 10, and the cavity tilt between the second screening layer and the middle particle discharging opening 10 has filter 11; Filter 11 is 30 ° with the inclined angle alpha of horizontal plane; Be provided with baker 12 in the cavity of filter 11 inboards, filter 11 inboard cavity outlets are connected with discharge outlet 13, and second sieve is layered as the sieve plate 9 along the cavity automatic lifting.
The first screening layer can come out the material screening less than aperture 5, and the second screening layer can come out the material screening of medium grain, and the second screening layer can rise along cavity; The large granular materials that is trapped on the second screening layer is ejected; Baker 12 can be with the drying materials that filters along filter 11, and moisture comes out from discharge outlet 13, removes moisture; Material is difficult for stopping up the screening layer, and screening efficiency improves.
