Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste incineration equipment, and particularly relates to a smoke dust purification device of an incinerator. BACKGROUND

[0002] With the improvement of people's living standards, the amount of urban and rural household garbage is increasing rapidly. At present, the treatment methods for household garbage are generally two kinds, one is sanitary landfill, and the other is incineration. Waste incineration has the characteristics of small land occupation, obvious reduction effect, and available waste heat resources compared with sanitary landfill. Therefore, waste incineration has gradually replaced the method of sanitary landfill. In addition, some waste needs to be treated separately when incinerated, so as to realize the classified treatment of solid waste and flue gas waste.

[0003] The waste incinerator is sent into the furnace, and the flue gas generated by the high-temperature burner in the combustion system is sent into the waste gas treatment system. Compared with landfill, waste incineration has the advantages of small land occupation, flexible site selection, short treatment period, rapid and substantial reduction of the volume of combustible waste, waste heat for power generation, sterilization and disinfection, and slag recycling. The waste gas treatment system generally captures particulate matter in the smoke dust through a bag-type dust collector. The bag-type dust collector has high-efficiency filtration of particulate matter, and ensures the effect of meeting the emission standard.

[0004] Leachate is high-concentration organic wastewater generated during the accumulation, fermentation and treatment of waste. It is mainly formed by the decomposition of organic matter in waste, the water contained in waste itself and the water generated during the degradation process. The leachate is mixed in the interior of the waste, making the humidity of the waste higher. The existence of the leachate can significantly prolong the waste incineration time and affect the working efficiency of incineration. After the waste is incinerated to the state of fly ash, the humidity of the fly ash is affected by the leachate, resulting in high viscosity. The fly ash is easily adsorbed on the surface of the bag-type dust collector, causing blockage problems, thereby affecting the incineration effect and service life of the device. SUMMARY

[0036] In the process of the threaded sleeve 303 continuing to move downward, the movable ring 305 rotates along the outer wall of the threaded sleeve 303, then the movable ring 305 drives the rotating shaft 309 to rotate synchronously through the sliding rod 308, so that the surface of the compression roller 310 extrudes and rolls the surface of the waste, the fixed ring 307 is arranged to buffer the compression roller 310 when it encounters uneven hard waste, and at the same time, the waste is more evenly dispersed in the incinerator body 2 through rolling, so that the efficiency of waste incineration is improved, and then the rotation of the reciprocating screw rod 302 drives the threaded sleeve 303 to continuously move up and down reciprocally, so that the waste is continuously rolled, and the rolling action of the compression roller 310 can also extrude and separate the leachate mixed in the waste, the separated leachate can also be evaporated more quickly, the incineration speed of the waste after separation from the leachate is improved, and the humidity of the fly ash generated after incineration is also reduced, so that the risk of blockage caused by the fly ash adsorbed in the incinerator body 2 is reduced.

[0037] Embodiment two, please refer to Figures 1-6 On the basis of embodiment one, in this embodiment, the bag filter mechanism 5 includes a filter bag 502 arranged in the inside of the purification box body 4.

[0040] More specifically, during the upward movement of the threaded sleeve 303, the threaded sleeve 303 drives the guide rod 311 to move synchronously through the limiting plate 304, and then the top of the guide rod 311 contacts the bottom of the connecting ring 504, and then the connecting ring 504 is extruded to move upward along the inner wall of the purification box body 4, and in the process, the connecting frame 505 and the connecting block 506 drive the bottom of the filter cloth bag 502 to move upward, so that the filter cloth bag 502 is folded and deformed, and the second spring 503 is compressed.

During the deformation of the filter cloth bag 502, the filter hole gaps on the surface of the filter cloth bag 502 change, and the position of the filter cloth bag 502 also changes. During the displacement, some particles such as fly ash adsorbed on the surface of the filter cloth bag 502 are separated, so as to avoid plugging the pores and affecting the filtering performance, delay the period of cleaning or replacing the filter cloth bag 502, and improve the work efficiency.

[0041] Embodiment three, please refer to Figures 1-7 On the basis of embodiment two, in this embodiment, the limiting vibration mechanism 6 includes a stop block 605 arranged on the inner wall of the purification box body 4.

[0042] The limiting vibration mechanism 6 includes an extrusion block 601, the top of the extrusion block 601 is fixedly connected with a first connecting plate 602, the top of the extrusion block 601 is fixedly connected with a second connecting plate 603, one end of the second connecting plate 603 facing the first connecting plate 602 is fixedly connected with a third spring 604, the other end of the third spring 604 away from the second connecting plate 603 is fixedly connected to one end of the stop block 605, the outer wall of the stop block 605 is slidably connected to the interior of the first connecting plate 602, and one end of the extrusion block 601 is fixedly connected with a fourth spring 606.

[0043] Further, the inner wall of the purification box body 4 is provided with a sliding groove 7, the side wall of the extrusion block 601 is slidably connected to the inner wall of the sliding groove 7, the other end of the fourth spring 606 away from the extrusion block 601 is fixedly connected to the inner wall of the sliding groove 7, the top outer wall of the guide rod 311 corresponds to the inclined surface of the outer wall of the extrusion block 601, and the outer wall of the connecting ring 504 corresponds to the inclined surface of the end of the stop block 605.

[0044] More specifically, in the process of sliding the connecting ring 504 upwards along the inner wall of the purification box body 4, the outer wall of the connecting ring 504 will contact and press the end inclined surface of the stop block 605, so that the stop block 605 presses and slides to the first connecting plate 602 and the second connecting plate 603, and then when the connecting ring 504 continues to slide upwards beyond the position of the stop block 605, the stop block 605 will be reset by the elastic force of the third spring 604, and then in the process of sliding the connecting ring 504 downwards along the inner wall of the purification box body 4 by the elastic force of the second spring 503, the outer wall of the connecting ring 504 will contact the end top of the stop block 605, and then be clamped, and then in the process of continuous downward movement of the guide rod 311, the outer wall inclined surface of the extrusion block 601 will be contacted and pressed, so that the extrusion block 601 slides to the inner wall of the sliding groove 7, and the fourth spring 606 is compressed, and in the process of sliding of the extrusion block 601, the stop block 605 will be moved synchronously by the second connecting plate 603 and the first connecting plate 602, and then the stop block 605 will gradually move away from the contact with the connecting ring 504;

[0045] Then the disengagement is completed, at this time the stop block 605 is no longer limited, and the connecting ring 504 is quickly reset by the elastic force of the second spring 503, and at the same time the connecting ring 504 will drive the bottom connecting end of the filter cloth bag 502 to move synchronously, and then in the process of completing the reset of the connecting ring 504, the filter cloth bag 502 will be stretched once, and the original folded state is quickly stretched, realizing the function of patting the surface of the filter cloth bag 502, so as to strip the dust layer attached to the surface of the filter bag, especially for sticky smoke dust, realizing the comprehensive effect of deep dust removal, surface cleaning, life extension and operation stability improvement.

[0046] The working principle of the application is: in the garbage incineration process, first, pull the handle of the feeding window 15 to drive the feeding window 15 to complete the overturning action, then pour the garbage to be incinerated into the inside of the conveying cylinder 12, after the garbage is filled, close the feeding window 15 to form a sealed space, at this time start the second motor 13, the output shaft drives the conveying worm 14 to rotate, the axial thrust generated by the worm screw structure continuously conveys the garbage into the incinerator body 2, because the garbage will produce leachate in the long-term storage process, after mixing with solid garbage, this kind of high humidity pollutants will significantly prolong the incineration period and reduce the overall processing efficiency.

[0047] To solve the above problems, the first motor 8 output shaft drives the rotating rod 9 to rotate, and the power is transmitted to the reciprocating screw rod 302 through the gear meshing transmission of the first transmission helical gear 10 and the second transmission helical gear 11. The rigidity connection of the fixed plate 301 and the base 1 ensures the stability, and the double guide sliding structure of the guide rod 311 in the base 1 and the purification box 4 forms a three-dimensional positioning system. When the reciprocating screw rod 302 rotates, the threaded sleeve 303 moves in the axial direction under the constraint of the limiting plate 304, so that the surface of the compression roller 310 is extruded on the surface of the garbage for rolling. By setting the fixed ring 307, the compression roller 310 can buffer when encountering uneven hard garbage, and the garbage can be dispersed more uniformly in the incinerator body 2, improving the efficiency of garbage incineration. Then the rotation of the reciprocating screw rod 302 drives the threaded sleeve 303 to continuously move up and down, so as to continuously roll the garbage. The rolling effect of the compression roller 310 can also extrude and separate the leachate mixed in the garbage. The separated leachate can also be evaporated faster, and the humidity of the garbage after incineration can also be reduced, reducing the risk of blockage caused by fly ash adsorbed in the incinerator body 2.

[0048] During the upward movement of the threaded sleeve 303, the threaded sleeve 303 will drive the guide rod 311 to move synchronously through the limiting plate 304. Then the top of the guide rod 311 will contact the bottom of the connecting ring 504, and then extrude it to move upward along the inner wall of the purification box 4. During the process, the connecting frame 505 and the connecting block 506 will drive the bottom of the filter bag 502 to move upward, so that the filter bag 502 is folded and deformed, and the second spring 503 is compressed. Then during the downward movement of the threaded sleeve 303, the connecting ring 504 will gradually move downward under the elastic force of the second spring 503. During the process, the filter bag 502 will be stretched and reset. During the deformation of the filter bag 502, the filter hole gap on the surface of the filter bag 502 will change, and the position of the filter bag 502 will also change. During the displacement process, some particles such as fly ash adsorbed on the surface of the filter bag 502 will be separated, avoiding the blockage of the pores and affecting the filtering performance, and delaying the period of cleaning or replacing the filter bag 502.
