SH type series rotary rotary screen working principle
The SH series rotary rotary screen is mainly composed of a motor, a reducer, a roller device, a frame and the like. The drum unit is arranged obliquely. The motor is coupled to the roller mechanism via a speed reducer to drive the roller mechanism to rotate about its axis. After the material enters the drum unit, due to the inclination and rotation of the drum unit, the qualified material (the product under the screen) is discharged through the screen of the outer circumference of the drum, and the unqualified material (the product on the screen) is discharged through the end of the drum. The SH series rotary screen roller unit is sealed by the sealing cover of the body to ensure that the equipment can effectively prevent dust from escaping during the working process and prevent dust pollution. When replacing the screen, you only need to open the body seal cover to replace it, which is easy to operate [2].
SH series round rotary screen product features
1. Wide adaptability of materials: Rotary screen is widely used in screening various materials. Whether it is inferior coal, slime, soot or other materials, it can be screened smoothly.
2. The feeding method is simple and diverse: the rotary screen feeding port can be designed according to the actual situation on the site. Whether it is belt, funnel or other feeding method, it can be fed smoothly without special measures.
3. High screening efficiency: The equipment can be equipped with a comb-type cleaning mechanism. During the screening process, the material entering the screening cylinder can be sieved according to the dirtiness and impurities, thus improving the screening efficiency of the equipment.
4. The sieve component is large and easy to enlarge: in the same size, the circular area is larger than other shapes, so the effective area of the screening is large, so that the material can fully contact the screen, so the sieve component per unit time Big. Because of its simple structure, convenient layout, novel and mature technology, it is easy to enlarge.
5. Low energy consumption: The rotary screen motor has low power, which is one-half to one-third of other sieve types. It handles the same amount of materials and runs only one-half of the other sieve types, so the energy consumption is low. .
6. The working environment is good: the whole screening cylinder can be sealed with a sealed isolation cover, which completely removes the phenomenon of dust flying, blocky splashing and the like during the screening cycle, and avoids pollution to the working environment.
7. Low noise of the equipment: During the operation of the rotary screen, the rotation speed is small, and the sealed isolation cover is isolated from the outside, so that the noise cannot be transmitted to the outside, thereby reducing the noise of the equipment.
8. Long service life and small maintenance: The rotary screen is composed of several ring-shaped nets. The total screening area is much larger than the screening area of other sieve types. In addition, the screening efficiency is high and the equipment running time is short. Therefore, the service life is long, the wearing parts are small, and the maintenance amount is small.
9. Convenient maintenance: the equipment can be opened and sealed. The upper cover can be disassembled, and the normal operation of the machine is not affected after disassembly, and the maintenance is very convenient.
Round rotary screen technical parameters
The following items should be noted during the use of the SH series circular rotary screen [3]
1. Equipment installation and adjustment should pay attention to:
(1) The machine horizontal deviation requirement is not more than 1 mm/m.
(2) All equipment of the equipment is not allowed to set up other objects, so as not to affect the strength and rigidity of the equipment.
(3) After installation, the installation tools should be removed, and no foreign matter is allowed inside or outside the screen cylinder.
(4) All the fasteners of the equipment should be firm and reliable, no looseness, and the installation and adjustment should be carried out. After further confirmation, the no-load test can be carried out.
2, no-load test
(1) No abnormal abnormal sound.
(2) Continuous operation for 2 hours, bearing temperature rise does not exceed 70 °C.
(3) After confirming that there is no abnormality in the no-load test, the load can be tested.
3, load test
(1) Start the equipment first, and then load it evenly until it is fully loaded.
(2) The equipment must not have excessive or significant impact sounds.
(3) The equipment is continuously operated for 8 hours, and the bearing temperature rise does not exceed 70 °C.
(4) Stop feeding before stopping, and stop the material in the sieve cylinder after it is completely discharged.
(5) It can be put into production and use in accordance with the above conditions.
(6) It is strictly forbidden to make adjustments while the equipment is running.
4. Lubrication and maintenance of equipment
(1) Always pay attention to and timely do the lubrication work of all parts of the equipment. Ensure the normal operation of the machine and extend the service life of the equipment.
(2) The grease used in this machine is a calcium-based grease.
(3) The lubricating parts of the machine must be filled with grease before leaving the factory. The user determines the lubrication cycle based on the specific operating conditions. The machine body has two lubrication parts, which are on the bearing block at the head and tail.
(4) Equipment lubrication should be carried out after stopping, and the motor and reducer should be maintained according to the instructions.
(5) It is strictly forbidden to make adjustments while the equipment is running.
5. Equipment maintenance and management
(1) Equipment should have special care management.
(2) Maintenance and repair of the equipment must be carried out after parking. It is strictly forbidden to carry out maintenance and repair while the equipment is running.
(3) Equipment management and maintenance personnel should always inspect the operation of the equipment, for example: whether the fasteners are reliable and whether the rotating parts are flexible. The equipment must be cleaned after the shift.
Plane rotary screen
The plane rotary screen is a kind of grain cleaning equipment that relies on the inertial centrifugal force of the weighted block to realize the plane rotation of the screen body. For different materials, the corresponding sieve, the inclination angle of the screen surface, the motor speed and the mass of the rotary body can be optimized. The comprehensive screening effect is suitable for the screening and grading of solid materials, and is widely used for the cleaning of wheat, rice and other foods [4].
PXZS200/250 plane rotary screen is mainly composed of sieve suspension bracket, human material port, screed box, universal joint suspension boom, sieve body, discharge box, sieve hanging bracket and driving device. The plane rotary screen adopts the motor to drive the pulley to rotate, which drives the biasing block to rotate around the shaft to generate an exciting force, so that the screen body produces a plane rotary motion [5].
Shaving rotary screen
In the production of modern particleboard, there are many kinds of raw materials used, many companies directly purchase wood chips and factory shavings, raw material specifications
