The application of old-fashioned vibration coal feeder in the country is more also, it is generally used in the output with a smaller bunker or the mouth of the funnel, for tilting the vibration coal feeder.Old-fashioned vibration coal feeder in the mouth under the coal bucket size is very small, Only after the fate of the material natural to the theme of equipment by the warehouse, through the vibration plate feeding, when the area and height of the pile is large, the material circulation is poor, coal in serious condition.Especially in large and medium-sized thermal power plant, the output of the system, and the condition of the silo outlet, the old-fashioned vibration coal feeder and more could not adapt.
At present, great, newly built home, medium-sized thermal power plant of large silo generally use the impeller coal feeder, ring-type coal feeder to coal equipment.Abroad, the upgrading of the silo feeding device after several ten years, Has now been widely used in large openings The activation of the output vibration coal feeder, Direct vibration of activation of the material inside the silo, An effective solution to coal and coal sprinkling is the problem, simple installation and maintenance, easy maintenance, small, effective and can improve the silo coal storage volume.
The theme of the activation of vibratory coal feeder and sealing connection under the silo, Arching or wedge inside the machine in direct contact with the material discharge plate silo, The vibration of plate and efficient transfer out of work to the top of the material, the vibration disturbance produced by the material energy loose and whereabouts of the disappeared persons.The material through a slot is transmitted to the lower part of the curve on both sides of coal feeder exports.Coal Feeder the vibration of the curve groove with specially designed to ensure that the freedom of the material discharging, even if it is the kind of coal with high viscosity can smooth out the coal.When the motor stops working, the warehouse of material auto-lock stopped the declining momentum, do not need to set the door of the gate.Vibration Feeder the vibration system is composed of vibrating motor and vibration of spring.Using the subthreshold resonance in a double-plastid vibration principle, the exciting force of small-power motor drive main body and obtain the linear amplitude.This vibration system with stepless speed control technology with coal output between the output from the least to the 100% regulation.
A, activation of material, not coal, to solve the bulk bin, plugging bunker
Activated coal feeder by using the special structure design, the function of the activation of a set of materials and integrates the functions of feeding, is designed to prevent plugging the design of coal feeder.At work, excited vibration of motor starting, Using the subthreshold resonance in a double-plastid vibration principle, a great exciting-vibration force vibration of the main body of the material, combined with a specially designed curved groove to ensure that the free-fall of material.Due to the discharge port is under the coal feeder opening, the fate of the material in the vibration the vibration of loose at the same time, so the vibration of the vibration of the material will not be more real.At the same time, the whereabouts of the coal feeder The Ministry of coal machine materials because of the force of gravity within the whereabouts of auto-feeder, In order to ensure the whereabouts of continuous materials designed specially for solving coal, large openings and activation of blocky structure, to avoid the phenomenon of coal.
Activated coal feeder and hopper or tube within the interface area much larger than the impeller coal feeder, Belt feeder Other forms of ring-type coal feeder to coal, For example, the activation of coal output of 750 tons/hour port on the machine within an area of 3.05 meters by 3.05 meters and output of 1500 t/h of activated coal feeder on the area of 3.35 meters by 3.35 meters.This will allow the smallest contraction section of a significant increase in silos, to avoid the possibility of arch in silo.
Activated coal feeder installed inside a specially designed activation block and the curve of cutting slot.Work, vaulted to the top of the activation of lateral vibration of fast and efficient transfer of materials, the disturbance energy produced by the vibration of loose materials to enable his whereabouts.Through the curve of the two sides of coal feeder trough is transmitted to the lower export.Coal Feeder the vibration of the curve groove combined with a specially designed to ensure that the free discharge of material, even if it is brown or other adhesive quality can smooth out the coal.
Two, low installation height can greatly save investment
Large opening structure of activated coal feeder, which can reduce the height of the silo and the convergent section; Unique in form of the material, and can greatly reduce the height of the device itself.In this way, can significantly reduce the silo and silo the height or depth of the tunnel, and the cost of construction costs.
Three, long service life, maintenance-free, high reliability
Activation of the starting point for the design of coal feeder for long-lived (30 years), 24 hours of continuous operation, maintenance-free.The feeder springs and vibrating motor and the service life of lining plate in 5 years.The usual maintenance is extremely rare and do not need maintenance shop, safe and reliable operation.The amount of material that can be adjusted on-line.
Activated coal feeder by frequency conversion speed regulation technology Can on-line continuous adjustment quantity, the quantity can range from zero to the maximum adjustment between the amount of design is especially suitable for coal blending system.
Four, low-power, large-amplitude
Activated coal feeder designed on the principle of vibration, sub-resonance Amplification of motor vibration by spring, resulting in a large vibration amplitude, so that the activated coal feeder in power, large output and reduce operating costs.
Five of the material, the belt does not run
The middle and lower the activation of coal machine by uniform design Material the whereabouts of activated coal feeder in belt conveyor to avoid the problem of deviation of the belt conveyer, reduces the cost of the repair and maintenance of belt.
Six, without the gate
Activated coal feeder adopts unique design can ensure the motor stopped when the vibration or sudden power failure, Warehouse material auto-lock stopped the declining momentum, without the gate, the device can be operated at the start.
Seven, environmental protection, and to reduce the personnel quota
The upper part of activated coal feeder and hopper sealed flexible connection, the coal from the mouth very close and seal device of belt conveyor.When a large number of feeding coal leakage phenomenon, greatly improve the work and the working environment.Because of the absence of any effort, and without the daily clean-up of leaking coal in each class, reduce the personnel quota.
Eight, the dynamic load is low, no special requirements on the basis
Activated coal feeder the vibration which is adopted for motor power is very low, the dynamic load of the motor is very small, low requirement for foundation, the equipment on the simple equipment support.
