Encyclopedia of machinery: operation instructions and application analysis of vibrating feeder

vibrating feeder is a continuous production feeding equipment, which has been widely used in mining production lines, metallurgical production lines, chemical production lines, power industry, building materials, as well as light industry, food, medicine and other industrial and mining departments. The vibrating feeder can be used as a feeding device for cement mills, belt conveyors, bucket elevators, crushers, crushers and viscous particles or powder materials in various industrial departments. In the production process of the above industrial and mining enterprises, materials can be fed quantitatively, evenly and continuously from the storage bin or hopper to the receiving device

1) the feeding is uniform, the output is easy to adjust, and it is easy to realize automatic control

2) the vibrating feeder has no rotating parts, so it is simple to maintain and does not need lubrication. The materials jump forward in the chute as a parabola and hardly slide on the surface of the chute, so the chute wear is very small, and the motor reducer is not required in use. Due to the above reasons, this machine saves oil and electricity, and the operation and maintenance cost is low

3) it can transport hot materials below 300 ℃

4) solid structure, small volume, light weight, convenient installation and operation

II. Main technical parameters

III. working principle silicon controlled controller is used together with electromagnetic vibration feeder to control the output of feeder. Since the feeder of the electromagnetic vibration feeder changes with the amplitude, and the amplitude changes with the current through the coil of the electromagnetic vibrator, the current through the electromagnetic vibrator can be controlled to adjust the feeding amount. This purpose is achieved by changing the conduction angle of silicon controlled rectifier

IV. process configuration

the process configuration of the vibrating feeder will directly affect its production capacity and performance. The following problems should be paid attention to in the design and layout of the outlet and chute of the storage bin or hopper on the upper part of the feeder

1) the layout of the silo or hopper outlet should try not to make the load of the silo directly press on the tank of the feeder. For this reason, a chute should be added between the outlet of the silo and hopper and the tank body of the key materials of the focus

2) the discharge opening width b of the silo or hopper must meet the following empirical formula: A-10 ≥ B ≥ () d, in the formula: D - maximum particle size diameter (mm) a - chute width (mm)

3) a gate shall be installed at the discharge port to adjust the opening of the discharge port and close the discharge port during equipment maintenance

4) in order to ensure the normal operation of the feeder, it is not allowed to consolidate any accessories on the chute

5) a dust-proof cloth cover can be set between the feeder chute and the chute, and a cover plate can be set on the chute to prevent dust

v. installation and adjustment make the experimental force automatically unload and test run

1) before installation, it is necessary to check the fastening of the screws in the following parts

in order to maximize the jacking bolts of the spring plate and give full play to the production capacity of the feeder before installation, the side baffle should be set in the factory when discharging the materials with relatively tight specific gravity (when the wrench length is 1.5 small, it is all meters along the material trough, which is of great significance to the study of computer control DZ1 ~: one person), The side will affect the coordination value of the feeder's object plate and the chute side plate. The air gap between the iron core and the armature should be checked and adjusted to 1.9 ~ 2.2mm to keep the plane of the iron core and the armature parallel and clean, and then the iron core frame and the feeding and discharging chute combined with the feeding trough should have a certain floating gap. Do not touch the feeding machine to avoid affecting the tightening of the adjusting bolts and fixing bolts one by one. The clamp bolts of the coil are also tightened to prevent the coil from loosening

2) hanging of feeder. Steel wire rope is recommended. It shall be hung on the member with sufficient rigidity. The feeder vibrates and generates noise

3) it is not allowed to have too much bin pressure on the feed chute of the feeder, otherwise the amplitude of the feeder will be reduced and the conveying speed of materials will be reduced

4) after the feeder is installed at the given position, check whether the groove direction of the chute is horizontal, otherwise the material will shift like one side during the conveying process

5) the feeding machine body and control box can be improved to meet the installation procedures of high heat-resistant gas equipment according to the general electric model LAN ut235m
