Abstract
The invention relates to a barometric pulse conveyance coal feeding machine which is composed of a funnel, a material tank, an electromagnetic valve, an air storage tank and the like. The upper portion of the funnel is connected with a coal bunker opening, the lower portion of the funnel is connected with the upper portion of the material tank, and the back portion of the material tank is provided with the electromagnetic valve and the air storage tank; when the electromagnetic valve is powered on, the valve is switched on, high-pressure air in the air storage tank quickly rushes to the back portion of the material tank to push coal in the material tank to move in the discharge opening direction, the coal on the upper portion of the material tank moves downwards for supplementary, and the electromagnetic valve is electrically controlled to be repeatedly and continuously switched on and switched off, so that the high-pressure air repeatedly and continuously pushes the coal in the material tank to move forwards to complete the feeding process. According to the barometric pulse conveyance coal feeding machine, a vibration excitation source of a vibration feeding machine is omitted, power consumption is greatly reduced, the materials are pushed to move forwards through the high pressure air conveyed into the closed tank, no pollution is generated to the ambient environment, and the machine is particularly suitable for an anti-explosion occasion of a coal mine. The barometric pulse conveyance coal feeding machine is simple in structure, stable in running and free of vibration noise and is energy-saving and environment-friendly best equipment.
Description
Technical field
The present invention relates to a kind of pneumatic pressure pulses conveying feeder, be mainly used in the industry even feeding fields to bulk material such as coal, chemical industry, electric power, building materials, metallurgy.
Background technology
Batcher is the feeding device that a kind of economic and technical norms are advanced in mine haulage system, the different materials such as block, granular, powdery can be given to various material feeding object uniformly, continuously from feed bin or drop shaft, such as: belt feeder, disintegrating machine, sieving machine, jigging machine, various vehicles etc..In colliery, metal is widely used with industries such as non-metal mine, electric power, building materials, chemical industry.
At present, in the batcher that the industry such as coal in China, chemical industry, electric power, building materials, metallurgical mine is used, the equipment distributing material under feed bin mostly uses various forms of oscillating feeder.Such as GZG type, GZY type, GZM type etc., broadly fall into elemental body oscillating feeder；Another kind of for electric and magnetic oscillation feeding device.Owing to, in its design structure, both there is some disadvantage.The former, owing to vibrating motor is directly connected with vibration cell body, therefore, the exciting force of vibrating motor generation directly does work in cell body, and during work, greatly, vibrating feed is unstable for noise, and cell body weld seam is excessive and easily split due to the power of shaking, and motor easily burns out；And the latter, electro-vibrating feeder there is also vibrating noise greatly, and electric magnet is easily damaged, and amplitude is difficult to adjust, and is not suitable for the defects such as coal mine explosion-proof occasion use.Be badly in need of in the market design a kind of operate steadily reliable, length in service life, noise are low, do not have the conveying feeder of any pollution.
Summary of the invention
For meeting mine needs, it is an object of the invention to provide a kind of simple in construction, easy for installation, operate steadily reliable, length in service life, noise are low, do not have the pneumatic pressure pulses conveying feeder of the special environmental protection of any pollution.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is: a kind of pneumatic pressure pulses conveying feeder, is made up of funnel, hopper, electromagnetic valve, air accumulator, bearing and connecting tube.Funnel 1: the top of described funnel 1 is connected with coal bunker mouth；Hopper 3: the upper feed inlet of described hopper 3 is connected with the bottom of funnel 1, makes the coal in coal bunker enter hopper 3 by funnel 1；The bottom of hopper 3 is provided with bearing 4 for supporting hopper 3；The rear portion of hopper 3 is provided with electromagnetic valve 5 and air accumulator 6.
One end of described electromagnetic valve 5 is connected by the rear portion of connecting tube 2 with hopper 3, and the other end is connected with air accumulator 6 by flange.The air inflow of hopper (3) is controlled by the opening and closing of electromagnetic valve (5)；Electromagnetic valve 5 is closed type solenoid electric valve, by the opening and closing of pulse control instrument autocontrol valve.When electromagnetic valve 5 is energized, valve is opened, and the pressure-air in air accumulator 6 rushes at rapidly the rear portion of hopper 3, promotes the coal in hopper 3 to move to discharging opening direction simultaneously, and now the coal on hopper 3 top moves downward and gives to supplement.Pulse control instrument controls the most continuously on of electromagnetic valve 5 and closes, and makes pressure-air promote the coal in hopper 3 to travel forward the most continuously, completes feeding process.
The air inlet pipe 7 of described air accumulator 6 is connected with air compressor, remains the air pressure in air accumulator 6 and has enough gas-storing capacities.
The present invention uses said structure compared with prior art to have following features.
1, the present invention is a kind of pneumatic pressure pulses conveying feeder, has cast out the exciting source of oscillating feeder, has promoted material to advance by the pressure-air being transported in airtight cell body, be that in feeder design concept innovates greatly.
2, present configuration is simple, operates steadily, does not has vibrating noise, and service life is long.
3, in the present invention, owing to coal is to run in airtight cell body, coal dust runs the most out, does not has any pollution to surrounding, is the splendid coal supply equipment of a kind of environmental-protecting performance.
4, owing to there is no moving component, maintenance capacity more than 90% can be reduced compared with other feeder.
5, microcomputer and electrical system can be passed through, it is achieved productivity ratio on the spot, remote auto control.
6, owing to eliminating vibrating motor or common electric machine, make power consumption be substantially reduced, be particularly well-suited to coal mine explosion-proof occasion, be the best equipment of a kind of energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is the structural representation of pneumatic pressure pulses of the present invention conveying feeder.
Fig. 2 is the A-A sectional view of Fig. 1 of the present invention.
In figure: 1-funnel, 2-connecting tube, 3-hopper, 4-bearing, 5-electromagnetic valve, 6-air accumulator, 7-air inlet pipe.
Detailed description of the invention
Comparison Fig. 1～2, pneumatic pressure pulses of the present invention conveying feeder, it is made up of funnel, hopper, electromagnetic valve, air accumulator, bearing and connecting tube.The top of funnel 1 is connected with coal bunker mouth, and its underpart is connected with the upper feed inlet of hopper 3, and the bottom of hopper 3 is provided with bearing 4 for supporting hopper 3；The rear portion of hopper 3 is provided with electromagnetic valve 5 and air accumulator 6；One end of electromagnetic valve 5 is connected by the rear portion of connecting tube 2 with hopper 3, and the other end is connected with air accumulator 6 by flange, and the air inlet pipe 7 of air accumulator 6 is connected with air compressor.
