Belt Conveyor safety norms, this article is mainly about conveyor line, then the following to introduce specific.
Conveyor line safety codes are:
(1) the conveyor line equipment must be interlocking, interlocking device are strictly forbidden to arbitrarily change or dismantled.
(2) using more than one conveyor jointly complete the delivery of materials or some sort of process, should set up central central control console.
(3) the conveyor line of control must be able to ensure the accuracy of the transmission performance and operation is reliable, can quickly cut off power supply in case of an emergency, conveyor can safely downtime.
(4) the central console is used to realize accurate control, so you have to set up the sound and light signals, to display a single switch action starting, stopping and accident situation.
(5) the conveyor line conveyor should follow the inverse direction of material flow transportation line by machine starting, along the direction of material flow delivery delay line by machine downtime. On the premise of guarantee the material overflow, can also allow starting at the same time or brake at the same time.
(6) conveyor channel between the minimum width and the height of the escalator, platform side guard railing should abide by the provisions of the relevant standards.
(7) in receiving conveyor conveyor line throughput must be greater than or equal to the feed conveyor throughput. Reversible when receiving and feeding conveyor throughput should be equal, but when load reverse feeding receiving conveyor throughput should be feed conveyor throughput of two times.
(8) at the transfer point charging station near the job position, must have one or more emergency stop switch or device, it is strictly prohibited to pile up materials and other products.
(9) remote start conveyor must be set when the sound and light signals, and the signal should be located in the operator capacity and range.
(10) conveyor line should be set in the normal lighting or portable lighting, risk in explosive gas, dust, or when you are working in a mixture of ring, should choose safe lighting lamps and lanterns.
(11) conveyor such as downtime because of an accident, should be checked in advance before starting again, find out the reason of this parking timely troubleshooting.
(12) conveyor shut down more than a month before reuse, must by the supervision of the personnel in charge of mechanical and electrical technology to test all the mechanical and electrical equipment inspection, check there is no problem to use.
(13) conveyor motor row between channels, high-speed operation should not rest stay near or drive.
(14) by the conveyor or relevant work indoor store inflammable, explosive materials are strictly prohibited.
(15) conveyor belt installation after do not allow the use of fire, electric welding processing frame, with special needs should take necessary precautions.
(16) the running conveyor, conveyor belt if should look down on fire extinguishing again, if the roller fire should be fire first stop again.

Grain cleaning sieve is suitable for different amount of impurity cleaning
Grain Cleaning Machine sieve cleaning in the equipment with advanced level. It has simple structure, small volume, high yield, wide scope of application, sealed performance is good. Using adjustable spiral Angle plate and the cleaning brush, can be suitable for different amount of impurity cleaning. Shard type and double open the door of cylindrical screen structure, make the operation and maintenance is simple and quick.
The machine after the material from the inlet feeding sieve cylinder, the rotating plate impact and transmission function, make the material of the cluster material have been scattered, and with a board make circular motion around the tube inner surface, under the action of centrifugal force, less than the material of mesh sieve rapidly, from the lower part of the body eduction closed, close to the cylindrical screen cleaning brush to keep on the cylindrical screen material cleaning. Is greater than the sieve hole is big miscellaneous playing board conveyor, the direction and exports to big miscellaneous eduction.
Mainly applied to food and feed processing, clear accessories in addition to miscellaneous, crumb material scattered, especially suitable for used as insurance screen after mixing machine.

Practical installation techniques and use of belt conveyor
Belt Conveyor at the end of the standard in order to ensure the conveyor belt is always at the center of the roller and the roller run online, installing a roller, frame and rollers, must meet the following requirements:
Set hang hang a conveyor belt conveyor belt, conveyor belt first article spread on no-load period of roller, wai after driving drum, apply on the roller of overloading section again. Hung a ribbon can use 0.5 1.5 t hand winch. In article taut band connection, the tension device of the drum should be moved to the limit position, on the car and spiral tension device to pull to move in the direction of transmission device; And pick up device to make the vertical roller moved to the top. Before the taut conveyor belt, should be installed reducer and motor, good braking device with tilting conveying confidential. Belt conveyor after installation, the need for idling of commissioning.
Support structure must be in a straight line, and keep the horizontal level. To this end, after driving drum and roller rack installation, should be the center line and level of conveyor final alignment. Then frame fixed in the base or on the floor. After fixed belt conveyor, can furnish the feeding and discharging device.
With the rapid development of science and technology, conveyor has spread to every corner of the human life and areas, use is also more and more widely. Save a lot of time for mankind, labor, People's Daily life is becoming more and more inseparable from the conveyor. Conveying machinery according to the operating mode is divided into: 1:2: belt conveyor screw conveyor 3: bucket elevator 4: roller conveyor 5: measuring conveyor 6:7: plate chain conveyor mesh belt conveyor, focus today about the installation of belt conveyor.
Installation engineering of belt conveyor, belt conveyor frame installation is from the frame, then install sections progressive middle frame, finally furnish tail stock. Before installing the rack, the center line of the first to pull on the length of the conveyor, keep the conveyor centerline in line is the important condition of normal operation of conveyor belt, so when installing sections frame, must aim at the centerline, leveling, as well as which frame to the centerline of the margin of error, the captain per meter is + / - 0.1 mm. But on the conveyor length error must not exceed 35 mm to the center of the frame. When all the single section setting and alignment, can connect every single day.
Install the roller in the frame, transmission device and tension device installed, can be installed up and down roller roller frame, make the conveyor belt has slowly to the curved and ways of the roller spacing for 1/2 ~ 1/3 of the normal roller spacing. Roller is installed, should make its rotary flexible light.
Driver installation drive, must pay attention to make the belt conveyor and belt conveyor drive shaft centerline vertical, make the middle of the width of the driving drum with the centerline of the conveyor, the axis of the gear reducer and parallel transmission axis. At the same time, all shaft and cylinder should be leveling. Axis horizontal error, according to the conveyor width, allowed in the range of 0.5 1.5 mm. In the installation drive at the same time, can install tail wheel tensioning device, such as tension device of drum axis, should be perpendicular to the center line of belt conveyor.
