Overview of the use of cleaning sieve

Wuhan, central grain depot using shaker model TQLZal80 × 200, this sieve type original common rice, noodle factory in liquidation phase after the procedure . As the

particularity of grain production , vibrating screen supplier in order to achieve satisfactory cleaning effect , in the selection and use of equipment to do the following:
Granary is now equipped with complete sets of equipment production operations are 50t / h, yield than rice, flour mill is much larger , and the larger impurity grain on the

market , the choice of such a sieve type, note that the best choice for screen surface width 1.8m sieve , sieve -type because the width of 1.8m is a dual inlet , to take full

advantage of oscillating screen screening

The effective width of the sieve surface processing , and 1.5m in width of the screen surface of screen type is a single inlet , the material layer is concentrated in the middle

of the screen surface , the screen surface itself is narrow , plus the problems, the flow can not meet 50t / h production requirements. The sieve -type light impurities

removal efficiency is higher, can better meet the production requirements ,

But pay attention to timely collection hopper cleaned , it is worth noting that boot with particular attention to light impurities auger rotates in correct direction ,

otherwise, once running reverse , causing blockage. ③ The sieve -type small miscellaneous cleaning effect is better, because the screen surface with a self-cleaning ball ,

clogging . However, the screen on the ropes,

Valley of other fibrous impurities to be very sensitive . If too many of these impurities , cleaning is not timely , it will live in a big mixed paste the screen surface , so

that the effective screen management area is reduced , causing some food grain exports flow to large complex , affecting equipment production and cleaning effect . Wuhan,

central grain depot in general use, a vehicle cargo

Shut down after it cleaned once , a long time such impurities , 20min non-stop on the machine easy clean up once .

How to exclude conveyor deviation

1 Adjust the belt conveyor idlers bearing belt in the middle of the entire belt conveyor idlers deviation , adjust the position to adjust the deviation ; idlers in the

manufacture of both sides of the mounting holes are worked into holes for be adjusted. Specific adjustment method , which specific method is biased belt

Side , which side idlers forward direction toward Belt feeder the belt forward, backward , or the other side . Figure 1 shows the direction of the belt upward deviation is lower roller

group should be located at the left, the upper roller group moved to the right place .

2 Install aligning roller group aligning roller Pan feeder group has many types such as an intermediate shaft type , four -link , vertical roller type, etc. The principle is the use of

block or roller rotates in the direction in the horizontal plane lateral thrust block or generate the automatic belt adjustment belt deviation reaches to the heart of the

purpose . Generally lose the belt

Sending machine or when the total length of the shorter run-time two-way conveyor belt using this method is more reasonable, because the shorter belt conveyors easier deviation

and not easy to adjust . And long belt conveyor is best not to use this method , because self-aligning roller group life belt use would yield

Students have been affected.

3 Adjust the drive pulley and the driven pulley and bend pulley position adjustment bend pulley belt deviation adjustment is an important part . Because a belt conveyor with at

least two to five rollers, all the rollers must be perpendicular to the installation location of the longitudinal direction of the belt conveyor centerline , if the partial

Oblique inevitable deviation is too large . Adjustment Method and its group of similar idlers . For the head drum as the drum belt deviation to the right , the right of the

bearing should be moved forward , the belt deviation to the left of the drum , the left bearing housing should be moved forward , also the corresponding will

After the shift left or right side bearing housings after the shift. Rear roller adjustment method and the head drum opposite. Adjustment method. After repeated adjustments

until the belt transferred to an ideal location. Adjust the drive or bend pulley in the best pre -install its exact location .

4 tension belt tension adjustment at the adjustment at the conveyor belt deviation adjustment a very important part . Hammer at the upper two tensioning idler pulley in addition

to other than perpendicular to the longitudinal direction of the belt should be perpendicular to the vertical line of gravity , which is to ensure its axis horizontal centerline

. Use screw

Tensioning screw or hydraulic tensioning cylinders , the tensioning roller bearing should be accompanied by two pan to ensure that the longitudinal axis of the drum

perpendicular to the direction of the belt . Specific method of adjusting the belt deviation adjustment of the drum at similar .

Introduction grain cleaning sieve

Cleaning sieve for separating the grain particle size, shape and weight similar type impurities such as stones , mud , metal particles block , such as glass and cinder .

Separation of wet and dry methods are two types:

       The device has a specific gravity of dry stoner and gravity grading station . Stoner in the proportion of food complete crushing plant inside is evenly fed into an inclined reciprocating

perforated plate ( scale orifice plate or wire braid ) , and controllable by an airflow leaving the fluidized state by a semi suspension weight flow

Down side discharge.

        Typical equipment for washing the wet wheat dryer , washing by the spiral groove and the vertical drying parts. Than double roller crusher the major impurities in the washing tank

sedimentation speed , accumulate on the bottom by a small screw conveyor to send to the discharge port ; wheat grain were floating to the big screw conveyor drying section ,

Separated from the surface to remove the moisture. Heavier stones, mud , etc. due to the vibration of reciprocating perforated plate facing the upper end of the moving close by

poly- stone district discharge. The way to provide airflow suction and blowing categories. Gravity grading station working principle and structure and the specific gravity

stoner similar : first food

Food together with impurities divided into two parts by weight , and then were to be cleaned , can reduce the number of devices or cleaning behind the switch to a smaller device

.
