Description

Airtight ribbon conveyer

Technical field

The utility model belongs to the conveying equipment technical field, is specifically related to the airtight ribbon conveyer of a kind of suitable coal delivery of boiler system.

Background technology

Ribbon conveyer is widely used in industries such as the energy, building materials, chemical industry, grain, it generally is made up of frame, drive unit, driving drum, carrying roller, changed course cylinder, sweeper etc., its operation principle is that conveyer belt is installed on driving drum, carrying roller, the changed course cylinder, drives conveyer belt operation the carrying out conveying of material by drive unit by the driving drum transferring power.Be transferred material by changed course cylinder end top pan feeding, from the bottom discharging of driving drum end.Traditional ribbon conveyer is made middle frame, the headstock, tailstock respectively by angle steel or channel-section steel and is formed frame, carrying roller is installed on the middle frame by carriage, driving drum, drive unit, sweeper are installed on the headstock, the degree of tightness that the changed course cylinder is regulated conveyer belt by the take-up device that is installed on the tailstock, gear wheel is installed on the middle frame, prevent that conveyer belt when operation from running the limit, usually, deflector chute also is housed at the pan feeding place of conveyer belt drops in the middle of the conveyer belt to guarantee material.

Traditional ribbon conveyer exists following deficiency:

One, equipment whole process is open type, airborne dust in the convey materials process, when particularly upstream device produces barotropic gas, as the boiler coal feeding system, the malleation furnace gases that boiler produces, cause coal dust and pernicious gas to leak, influence working environment, even the injury field personnel.Airborne dust is not recyclable, causes waste of raw materials.

Its two, belt speed is non-adjustable, being transferred material can not variable, promptly in material conveying process, how many material upstream equipment just carries to how many material, can not satisfy upstream device changes the feed amount according to condition of production needs requirement.

Its three, can not measure, write down printing, storage data to convey materials.If need convey materials is measured, must add an electronic belt scale in addition.The mechanical part of electronic belt scale is similar to ribbon conveyer, and conveyer belt is installed on carrying roller, driving drum, the changed course cylinder, by the driving drum transferring power.The electronic belt weighing principle is, flows to computer and carries out data and handle accumulating weight by claiming frame, LOAD CELLS, speed measuring device, tachogenerator to convert weight, belt speed in the store list bit time to the signal of telecommunication in the material conveying process.Its weak point is that equipment is its measurement accuracy of factors influence such as open type, extraneous wind-force, sleet.Simultaneously, electronic belt scale also need take production site.

Though, also have at present title frame, speed measuring device be installed in and weigh on the ribbon conveyer and test the speed, in the hope of reaching the purpose of metering, but can not solve the speed governing problem of ribbon conveyer, and to the ribbon conveyer design, self is equipped with high requirement ribbon conveyer thus, the result mostly measures inaccurate, even can't use.

Summary of the invention

The purpose of this utility model is at the above-mentioned defective that exists in the prior art, and a kind of airtight ribbon conveyer of measurable adjustable speed is provided.

The utility model is to realize above-mentioned purpose by the following technical solutions: this airtight ribbon conveyer, comprise: frame, be installed on the conveyer belt on driving drum, carrying roller, the changed course cylinder, drive the drive unit of driving drum, the take-up device that is connected with the changed course cylinder, be installed on the gear wheel of frame both sides, and be installed on the other sweeper of driving drum; Be characterized in: frame adopts box typed structure, and is positioned on the support, and the bottom that the top that frame is positioned at the changed course cylinder is provided with charging aperture, be positioned at driving drum one end is provided with discharging opening; Described drive unit comprises variable-speed motor and reductor, and is installed on the outside of frame; Title frame, speed measuring device are installed in the frame, and are connected with the external piloting control computer by sensor.

Described frame comprises frame main body and airtight deflector chute, adopts bolt to connect between frame main body and the airtight deflector chute, and upper rack is provided with cover plate, adopts box fastener to connect between cover plate and the frame.

The utility model has prevented that dust is raised in the convey materials process outward owing to adopted the airtight frame of box-type, has reduced environmental pollution.When downstream equipment produced barotropic gas, the material of ejection still dropped in the frame and carries again.And the integral rigidity of box-type frame, good stability have satisfied the requirement of metering device certainty of measurement.Transmission device adopts buncher to realize automatic speed regulation in the convey materials process.Utilize modern control principle, cooperate computer processor CPU and display, printer etc., realize automatic speed regulation, metering, printing, storage data.
