Abstract
The utility model discloses a classifying screen with a scraper, which comprises a driving motor, a transmission belt, a spindle and an outer casing. One end of the outer casing is provided with a feed inlet, the other end of the outer casing is provided with an impurity discharge outlet, the bottom of the outer casing is connected with a discharge bin, a screen cavity formed by screen plates in a surrounded manner is arranged inside the outer casing, the scraper is arranged on the spindle in the screen cavity, a connecting auger is arranged between the feed inlet and the screen cavity, the screen cavity consists of a plurality of screen sections, screen holes at the screen sections are gradually enlarged from the feed inlet to the impurity discharge outlet, bins are arranged at the bottom of the outer casing in position correspondence to the screen sections, and the number of the bins is equal to that of the screen sections. The classifying screen with the scraper is capable of classifying grain under the classifying screen into different grain size grades.
Description
Technical field
The utility model relates to a kind of shaft screen, especially a kind of shaft screen with grading function.
Background technology
Shaft screen is a kind of sieve tool commonly used in the Feed Manufacturing process; Be generally used for powder or impurity in the products of separated, the centrifugal scraping plate structure is adopted in shaft screen of the prior art inside more, utilizes scraper plate to stir material and passes through sieve plate; Reach the purpose of screening; But this shaft screen can only be simply is two kinds of oversize and screenings with material screening, and can not carry out the sizing screening of many grain size categories to material.
The utility model content
The technical problem that utility model will solve is: a kind of scraper plate classifying screen is provided, and this scraper plate classifying screen can be divided into a plurality of grain size categories with screenings.
The technical scheme that the technical solution problem is adopted: a kind of scraper plate classifying screen; Comprise drive motors, driving belt, main shaft, shell body, be provided with charging aperture at shell body one end, the other end is provided with impurity outlet, and the shell body bottom connects the discharging hopper; Shell body inside is provided with the screening chamber that is surrounded by sieve plate; On the main shaft of screening in the chamber, be provided with scraper plate, be provided with to be connected between charging aperture and screening chamber and twist cage, said screening chamber section is made up of a plurality of sieves; Sieve aperture along each sieve section of charging aperture to impurity outlet direction increases piecemeal, housing bottom setting outside and sieve hop count order and the corresponding hopper of each sieve fragment position.
Improvement as the utility model: said screening chamber is made up of for two sections dusting cover section, scalping section along charging aperture to impurity outlet direction, housing bottom setting outside and dusting cover section, the corresponding fines hopper of scalping section and coarse fodder hopper.
Further improvement as the utility model: the edge at scraper plate is provided with rubber flap.
Preferred version as the utility model: said rubber flap is through being bolted on the scraper plate.
Preferred plan as the utility model: said scraper plate is three, and angle is 120 degree between adjacent scraper plate.
Beneficial effect: the scraper plate classifying screen of the utility model; Because adopted said screening chamber to be made up of a plurality of sieve sections, the sieve aperture that respectively sieves section along charging aperture to impurity outlet direction increases piecemeal, housing bottom setting is outside sieved the technical characterictic of the corresponding hopper of fragment position with sieve hop count order and each; Material is successively through each sieve section during work; The screenings that sieves out from each sieve section falls into corresponding hopper, and last oversize is discharged from impurity outlet, therefore; The scraper plate classifying screen of the utility model once just can be divided into a plurality of grain size categories with screenings, has improved the screening operating efficiency; Owing to adopted said screening chamber to constitute for two sections by dusting cover section, scalping section along charging aperture to impurity outlet direction; The technical characterictic of housing bottom setting outside and dusting cover section, the corresponding fines hopper of scalping section and coarse fodder hopper makes the scraper plate classifying screen of the utility model can the quick screening of material be fines, coarse fodder and thick assorted; Owing to adopted the technical characterictic that is provided with rubber flap at the edge of scraper plate, overcome the hard metal scraper plate and be prone to the drawback that causes the sieve plate to damage, prolonged the service life of sieve plate; Reduced production cost; Simultaneously, the breakage rate when rubber flap can also reduce material screening, the quality of raising finished product; Owing to adopted said rubber flap through being bolted to the technical characterictic on the scraper plate, make that the rubber flap of the utility model can be separately, replacing fast, reduced the operation expense of machine; Because having adopted said scraper plate is three, angle is 120 degree between adjacent scraper plate, makes screening effect, the operating efficiency of the scraper plate classifying screen of the utility model reach the best fit state.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
Fig. 1 is the structural representation of the scraper plate classifying screen of the utility model;
Fig. 2 is that the A-A of scraper plate classifying screen of the utility model is to view.
The specific embodiment
As shown in Figure 1; The scraper plate classifying screen of the utility model comprises drive motors 9, driving belt 8, main shaft 11, shell body 7, is provided with charging aperture 2 at shell body one end, and the other end is provided with impurity outlet 13; The shell body bottom connects discharging hopper 12; Shell body inside is provided with the screening chamber 10 that is surrounded by sieve plate 6, on the main shaft of screening in the chamber, is provided with scraper plate 5, is provided with to be connected between charging aperture and screening chamber and twists cage 1; Said screening chamber is made up of for 62 two sections dusting cover section 61, scalping section along charging aperture to impurity outlet direction, housing bottom setting outside and dusting cover section, the corresponding fines hopper 121 of scalping section and coarse fodder hopper 122.In the practical work process, according to different grading needs, adopt the screening chamber to be made up of a plurality of sieve sections, the sieve aperture that respectively sieves section along charging aperture to impurity outlet direction increases piecemeal, and housing bottom setting is outside sieved the corresponding hopper of fragment position with sieve hop count order and each.
As shown in Figure 2, be provided with rubber flap 3 at the edge of scraper plate, rubber flap is fixed on the scraper plate through bolt 4, and three scraper plates are set on main shaft, and angle is 120 degree between adjacent scraper plate.
