These devices can be removed dust in various degree, but exist line clogging, and dust exhaustor stops up, secondary pollution, water, electricity, waste of raw materials, construction cost height, the high deficiency of operating cost.
Summary of the invention
The purpose of this utility model is in order both to improve dust removing effects, to reduce the one-time construction input and the operation expense of dust collector again, reaching high-effective dust-removing, the effect of environmental protection and saving.
Self-acting negative pressure automatic dust removing apparatus described in the utility model comprises support, driven roller, carrying roller, belt conveyor, swabbing pig, seal bootr, fully sheathed case, dust shield and blanking port.The transversal surface of seal bootr is the ∏ font, covers in the top of belt conveyor.The lower-left end of seal bootr is equipped with fully sheathed case, prevents that the dust of driven roller, swabbing pig and return belt generation is excessive.Dust shield is loaded on the seal bootr.Be provided with electric fan in the dust shield.Blanking port is located on the seal bootr.A plurality of envelopes in the leakage that have longitudinally are set in the seal bootr.The seal bootr two ends are provided with the leakage covering.Spray moisturing device is housed in the seal bootr.Two side lower parts of seal bootr are equipped with the liner plate by the stay bearing plate supporting.Liner plate, stay bearing plate, belt conveyor constitute inclusion seal to seal bootr.
The raw material that belt conveyor of the present utility model is carried is fallen belt conveyor at the corresponding levels from the upper class belt conveyor through blanking port.Near the blanking port belt conveyor uses the seal bootr sealing.Two side plates of seal bootr, stay bearing plate and belt conveyor constitute inclusion seal, and the two ends of seal bootr adopt covering to constitute the sealing of leakage.At the two ends of blanking port, adopt spray moisturing device to spray steam or atomized water.Coal dust after squirting directly drops on the belt conveyor, has avoided wastage of material.In thermal power plant, squirt the surplus vapour that can adopt power plant.In seal bootr inside, adopted envelope in the multistage spacer assembly, to reduce wind speed and dust concentration.Electric fan is installed in the dust shield, and dust shield is installed in the two ends of seal bootr, and air suctiton inlet forms the negative pressure cavity in the seal bootr, and the exhausr port of dust shield is the direct exhaust to atmosphere of the gas of compliance with environmental protection requirements.
The utility model has the advantages that:
1. dust collector is simple in structure, and it is low to build cost of installation.
2. conserve water in service.
3. pipeline is few, and daily operating maintenance is simple.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A section drawing of Fig. 1.
Among the figure: 1. seal 7. spray equipments, 8. blanking ports, 9. malleation chambeies, 10. suction ports, 11. swabbing pigs, 12. belt conveyors, 13. liner plates, 14. stay bearing plates, 15. carrying rollers, 16. return belts, 17. driven rollers, 18. seal bootrs, 19. supports in fully sheathed case 2. coverings 3. dust shields 4. electric fans 5. negative pressure cavities 6.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, self-acting negative pressure automatic dust removing apparatus described in the utility model comprises support 19, driven roller 17, carrying roller 15, belt conveyor 12, return belt 16, swabbing pig 11, suction port 10, seal bootr 18, fully sheathed case 1, dust shield 3 and blanking port 8.The transversal surface of seal bootr 18 is the ∏ font, covers in the top of belt conveyor 12.The lower-left end of seal bootr 18 is equipped with fully sheathed case 1, prevents that the dust of driven roller 17 and swabbing pig 11 and return belt 16 generations is excessive.The dust shield 3 that electric fan 4 is housed is loaded on the seal bootr 18.Dust shield 3 inflow points form negative pressure cavity 5.Blanking port 8 is located on the seal bootr 18.Blanking port 8 inflow points form malleation chamber 9.A plurality of envelopes 6 in the leakage that have longitudinally are set in the seal bootr 18.Seal bootr 18 two ends are provided with leaks covering 2.Spray moisturing device 7 is housed in the seal bootr 18.Spray moisturing device 7 can be a shower nozzle.Two side lower parts of seal bootr 18 are equipped with the liner plate 13 by stay bearing plate 14 supportings.Liner plate 13, stay bearing plate 14,12 pairs of seal bootrs of belt conveyor 18 constitute inclusion seal.
Principal feature of the present utility model is:
1. dust collector adopts totally-enclosed cover to carry out totally-enclosed to the dirt source
For the both sides of seal bootr, adopt the inclusion seal mode.For the seal bootr two ends, adopting has leakage sealed mode.By the combination of two kinds of sealing means, can carry out complete closed to dust source, dust only may be excessive from the two ends of belt conveyor, can reduce overflowing of dust to a great extent like this.
2. spray moisturing device
Because adopted the totally-enclosed measure of dust source, it is inner to be enclosed in totally-enclosed cover to dust.And then by spray moisturing device sprinkling steam or atomized water, so most of dust can make the dust that is suspended in the seal bootr inner air be reduced to very little concentration squirting back landing recovery automatically.
3. multi-stage isolation device dedusting
When coal or the frangible raw material of other graininess when the upper class belt conveyor falls, can bring portion of air into and form induced air, operating belt conveyor and electric fan can make induced air horizontal motion in seal bootr; Thereby making to fly upward at seal bootr in-to-in dust is difficult for falling.And induced air can be carried dust secretly and spill into the atmosphere from the two ends of belt conveyor.For this reason, envelope in seal bootr inside is provided with multi-stage isolation device (dust-break curtain) formation cooperates the seal bootr two ends that the spacer assembly covering is set.So not only reduced seal bootr in-to-in wind speed, helped the dust landing, made dust concentration more and more lower, and reduced the air quantity that overflow at the seal bootr two ends along the belt conveyor direction.
4. the automatic dedusting of negative pressure
The sealing that stops flour dust overflow is called interior envelope, stops that the sealing that ambient atmosphere enters seal bootr is called covering.Between interior envelope covering, use electric fan to bleed.The air that blower fan is drawn into directly is discharged in the atmosphere through exhausr port, thereby forms a zone of negative pressure at the ventilation inlet of electric fan.Zone of negative pressure prevents seal bootr in-to-in flour dust overflow.Electric fan sucks, and is the very low gas of the dust concentration that leaked out by interior envelope and from the miscellaneous gas of covering suction air.By regulating interior envelope, covering and fan delivery, can be so that the mixed gas dust concentration that exhausr port is discharged reaches environmental demands.
