SH type rotary screen for a special screening of compound fertilizer, the four screening, of which there are two sections of the finished product area.SH type rotary screen with a silo, Silo bottom fan-shaped gate, Roughage roughage section of chute can be directly sent to the transport machinery, To facilitate the process layout, user such as the requirement that only a section of the finished product area, namely, the three rotary screen should be noted when ordering.
The working principle of SH series of rotary screen:
SH series rotary screen the main motor, reducer, drum unit, frame and other institutions.Tilting device of the drum layout.The electric motor through reducer, and the cylinder body are connected together, driving roller body about its axis of rotation.When the materials enter roller device, Due to inclination and rotation of the drum device, so that the qualified material (undersize) by the cylindrical drum sieve, unqualified material (oversize) by the end of the cylinder is discharged.SH series of rotary screen roller sealing cover sealing device through the body, so as to ensure the equipment in the course of their work, effectively prevent the escape of dust to prevent dust pollution.When the replacement screen, simply seal to open the body can be replaced and convenient operation.
Product characteristic: the SH series rotary screen
1. The wide adaptability of materials: widely used in all kinds of material of rotary screen size, whether it is coal, coal, or soot, and other materials, screening is carried out smoothly.
2. A variety of feed is simple: According to the actual design of rotary screen feed, whether belt, funnel or other feed, don't have to take special measures, can the smooth feeding.
3. The high screening efficiency: Equipment can be provided with a comb-type sieve cleaning mechanism in the screening process, no matter how dirty the material into sieve tube, multi-clutter can be screening in order to improve the screening efficiency of the equipment.
4. The major component of the screen, Easy to scale: In the same size, The area of a circle is larger than any other area of the shape, so the effective area of the screen big, full access to screen the materials, so the big screen components in unit time.Because of its simple structure, the arrangement of convenience, new technology and the characteristics of a mature, easy to scale.
5. Its low energy consumption: Rotary screen a small-power motor, the other screen type from 1/2 to 1/3, the same amount of processing the other screen-type material and the running time is only 1/2, so that the energy consumption is low.
6. The working environment is good: The entire screening and sealing the tube can be sealed isolation hood, Complete removal of dust in the screening process, the massive splash of sub-phenomena such as avoiding the pollution of the working environment.
7. Equipment and low noise: In the operation of rotary screen, because of small rotating speed, and sealed isolation hood with the outside world, so that the noise cannot be delivered to the outside, thereby reducing equipment noise.
8. The service life is long, A small amount of maintenance: Rotary screen is composed of a number of ring-shaped network, The total screen area is far greater than other screen-type sieving area In addition, high screening efficiency, equipment operation time is short, so long service life less easyworn parts and little maintenance.
9. The convenient maintenance: equipment sealing isolation on the cover can be opened, open it later without affecting the normal operation of the machine, and repair are very easy.
The main technical parameters of rotary screen as follows:
SH series rotary screen using the process should pay attention to the following matters:
1, Equipment installation, adjustment should be attention:
(1) The deviation of the level of the machine requires less than 1mm/m.
(2), All the agencies did not allow the erection of equipment and other items, so as not to affect the strength and stiffness of the device.
(3), Installation tool and so on should be removed after the installation is completed, residual foreign body in the sieve tube have not allowed inside and outside.
(4), Equipment for all fasteners should be set solid and reliable, without shake a phenomenon, install, adjust the order, further after confirmation, you can load test.
2, No-load test
(1) In which no single abnormal noise
(2) 2 Hours of continuous operation, the bearing temperature rise of less than more than 70.
(3) Confirmed that the no-load test run after the test is no exception.
3, The load test run
(1) Should be the boot device, only after the normal functioning of uniform loading, until the full load.
(2) There shall be no excessive or significant impact sound equipment.
(3) Equipment for continuous operation for 8 hours, bearing temperature rise of not more than 70 degrees Celsius.
(4) Prior to parking stop feeding, the question of screening duration on sizing material completely before discharge to stop.
(5) In accordance with the above-mentioned conditions can be put into production use.
(6) No adjustment in equipment operation.
4, The lubrication and maintenance of equipment
(1) Regular attention and timely lubrication of every part of the equipment.To ensure the normal operation of the machine, to extend the useful life of the equipment.
(2) This machine is used for grease calcium base grease.
(3) The machine is part of the Lubricant filled with grease before they leave the factory.The user according to the specific use conditions to determine the lubrication cycle.Equipment there are two parts of the body, the head and tail of the bearing seat.
(4) The lubrication of equipment should be carried out after parking, motor and reducer in accordance with its instructions.
(5) It is prohibited in the operation of equipment to adjust.
5, The maintenance and management of equipment
(1) The management of the equipment should be free of care
(2) Equipment maintenance and repair must be carried out after stopping.When is prohibited in the operation of equipment maintenance and repair.
(3) Equipment management, maintenance personnel should inspect the operation of the equipment, for example: the reliability of the solid pieces, whether to rotate the rotation is flexible.After sweeping is an essential equipment of dirt.
