Abstract
The invention discloses a boiler fuel delivery mechanism comprising a material storage hopper, a frequency conversion motor, an air blower, a feed screw and a cylinder with one opened end and one closed end. The opened end of the cylinder is connected to one side of the material storage hopper, the feed screw penetrates the rear portion of the material storage hopper to arrange in the cylinder, and the transmission end of the feed screw penetrates the closed end of the cylinder to connect to the output shaft of the frequency conversion motor; a material leakage port is arranged on the lower portion of the cylinder and is connected to a suction port of the air blower, and the air outlet of the air blower is connected to the hearth of the boiler through a feed channel. The mechanism is capable of delivering powder or granular fuel to the combustion hearth of the boiler automatically and has the advantage of high automation level and simple structure, labor force is reduced greatly, and the fuel feed can be controlled.
Description
Technical field
The present invention relates to a kind of conveying equipment, be specifically related to a kind of boiler oil conveying mechanism.
Background technology
Boiler is a kind of energy conversion, and the waste heat in the heat energy that its operation principle mainly utilizes fuel combustion process to discharge or industrial production heats the water in boiler, makes water reach required temperature or the steam that forms certain pressure is outwards carried again.Energy generally to boiler input comprises the chemical energy in fuel or the heat energy in high-temperature flue gas, and steam or the high-temperature water for the having certain heat energy that outwards export, be widely used in thermal power station, locomotive, industrial and mining enterprises etc.The heating fuel of boiler generally has coal, electricity or is similar to the agriculture and forestry organic waste materials such as wood, stalk, sawdust, bagasse, rice chaff.The high defect of cost is there is in electricity consumption as the heating fuel of boiler; Although and cheap as the heating fuel of boiler with coal, coal is limited resources and coal produces the gas of the contaminated environment such as carbon dioxide, sulfur dioxide in combustion process, is unfavorable for energy-saving and emission-reduction; By agriculture and forestry organic waste material through being pulverized and mixed, obtain powdery or granular fuel after the PROCESS FOR TREATMENT such as oven dry, then there is as the heating fuel of boiler the feature of sufficient combustion, environmentally safe.
At present, when adding powdery or granular agriculture and forestry organic waste material as combustion fuel in boiler, be generally rely on manually to add.Manually add the following defect that the agriculture and forestry organic waste material fuel such as powdery or granular wood chip, rice chaff exists:
1) need to add in boiler continually, labour is large, automaticity is low; And the phenomenon of airborne dust is easily there is in the process added, harmful effect is caused to the physical and mental health of workshop condition and workman;
2) addition can not adjust by the demand of boiler combustion, even because the amount that adds is too much, causes fuel to pile up, insufficient, the flue gas phenomenon such as heavily of burning.
Summary of the invention
For above-mentioned deficiency, technical problem to be solved by this invention is to provide a kind of boiler oil conveying mechanism, it can in the burner hearth of trend boiler conveying powdered or granular fuel, there is automaticity high, the uniform feature of addition.
For achieving the above object, the present invention is realized by following scheme:
A kind of boiler oil conveying mechanism, comprise storage bin hopper, also comprise the cylinder that variable-frequency motor, air blast, feeding spiro rod and the one end open other end are closed, the openend of described cylinder is connected with the side of storage bin hopper, and described feeding spiro rod is through to be located at behind the inside of storage bin hopper in cylinder and to be connected with the output shaft of variable-frequency motor after the shell of the driving end of feeding spiro rod through the blind end of cylinder; The below of cylinder offers Lou expects mouth, and described leakage material mouth is connected with the inlet scoop of air blast by conveying passage, and the air outlet of air blast is connected with the burner hearth of boiler by feeding channel.
In such scheme, described junction of leaking material mouth and conveying passage has gap, and the inlet scoop that set gap is conducive to air blast sucks air, promotes the ventilation of air blast.
In such scheme, described conveying passage is placed in the sidepiece of Lou expecting mouth near the feeding end leaking material mouth, and namely with leakage, conveying passage expects that mouth is contactless connection, and the inlet scoop contributing to air blast sucks air.
The present invention carries the dusty fuel in storage bin hopper by feeding spiro rod is mobile in cylinder and in the space of storage bin hopper, dusty fuel stays through the leakage material mouth of cylinder, then sucked by air blast, then the powdery sucked finally is delivered in the burner hearth of boiler by the air outlet of air blast, feeding spiro rod is driven by variable-frequency motor, can not need so to be manually just able to continuously to add fuel in boiler, and by regulating the transmission speed of the frequency adjustment feeding spiro rod of variable-frequency motor, and then realize the addition of adjustment fuel.
Compared with prior art, beneficial effect of the present invention is:
1) do not need artificial interpolation, automaticity is high, greatly reduces labour, and does not occur the situation of workshop dust from flying, is conducive to improving workshop condition;
2) by variable-frequency motor control feeding spiro rod can according to the combustion case in boiler the addition of timely fuel metering, make the fuel combustion in boiler abundant, have that using energy source is high, the simple feature of structure, be applicable to conveying powdered or granular light Fuel, as coal grain, stalk etc. after wood chip, sawdust, pulverizing.
Accompanying drawing explanation
Fig. 1 is the top view of this boiler oil conveying mechanism.
Number in the figure is: 1, storage bin hopper; 2, variable-frequency motor; 3, cylinder; 4, feeding spiro rod; 5, conveying passage; 6, air blast; 7, feeding channel.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further explained, but not in order to limit the present invention.
As shown in Figure 1, a kind of boiler oil conveying mechanism, comprise storage bin hopper 1, also comprise variable-frequency motor 2, air blast 6, the cylinder 3 that feeding spiro rod 4 and the one end open other end are closed, the openend of described cylinder 3 is connected with the side of storage bin hopper 1, described feeding spiro rod 4 is through being located in cylinder 3 behind the inside of storage bin hopper 1, and be connected with the output shaft of variable-frequency motor 2 after the shell of the driving end of feeding spiro rod 4 through the blind end of cylinder 3, the below of cylinder 3 offers Lou expects mouth, described leakage material mouth is connected with the inlet scoop of air blast 6 by conveying passage 5, the air outlet of air blast 6 is connected with the burner hearth of boiler by feeding channel 7.
Described feeding spiro rod 4 can move at cylinder 3 and with the horizontal space of the storage bin hopper 1 of cylinder 3 on sustained height under the driving of variable-frequency motor 2, make to be placed in powdery in storage bin hopper 1 like this or granular fuel is delivered in cylinder 3 by feeding spiro rod 4 at leisure, constantly, when the leakage material mouth be provided with below cylinder 3, fuel, by the suction of air blast 6, is finally transported in boiler.In the present embodiment, the conveying passage 5 adopted and feeding channel 7 form for the tubing that is made of plastics or made by tarpaulin material, can also be that other materials are made certainly.
In such scheme, described leakage material mouth can directly be connected with conveying passage 5, can also be have gap in both junctions, so that the inlet scoop of air blast 6 has air to enter; Concrete syndeton is: described conveying passage 5 is placed in the sidepiece of Lou expecting mouth near the feeding end leaking material mouth, and namely conveying passage 5 and leakage expect to be connected for contactless between mouth.
