Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a fluff and dust filtering and purifying device for waste gas treatment. Background Technique

[0002] Waste gas treatment, also known as waste gas purification or waste gas treatment, mainly aims at treating industrial waste gas generated in industrial sites, such as dust particles, flue gas and soot, odor gas, toxic and harmful gases, etc. There are various methods for waste gas treatment, including physical methods, chemical methods, biological methods, etc. The choice of specific methods depends on factors such as the composition, concentration of the waste gas and the requirements for treatment efficiency.

[0003] When some waste gas with fluff and dust is subjected to waste gas purification treatment, the fluff and dust need to be filtered out, and then the harmful gas is filtered. Most of the current purification devices set up a filter cylinder that only allows gas to pass through when pumping air, so that when pumping waste gas, the filter cylinder can block the fluff and dust in the waste gas, thus realizing the function of filtering fluff and dust. However, most of these fluff and dust will adhere to the filter mesh on the inner wall of the filter cylinder. If it is not cleaned for a long time, the gas cannot pass through, and each cleaning requires manual entry into the purification chamber for cleaning, and such a cleaning method is relatively cumbersome.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

Filtration and purification units 8 are provided in the purification chambers 11. The tops of the filtration and purification units 8 are installed in the bottom wall of the exhaust chamber 21. The exhaust chamber 21 facilitates the discharge of gas.

[0036] Among them, the filtration and purification unit 8 includes a cylinder 85. The cylinder 85 is installed above the bottom wall of the exhaust chamber 21. The piston rod at the bottom output end of the cylinder 85 is fixedly connected to a support plate 86. Filter cartridges 81 are provided at the ends branched out from the plate body of the support plate 86. Jetting mechanisms 84 are provided in the filter cartridges 81. The upper ends of the jetting mechanisms 84 are connected to a gas delivery pipe 83. The other end of the pipe body of the gas delivery pipe 83 away from the jetting mechanism 84 extends to the outside of the exhaust box 2 and is connected to the pulse pump 3. The pulse pump 3 uses the high-pressure gas pulse technology to eject gas to the gas delivery pipe 83 by blowing compressed air.

[0037] Among them, an intake box 4 is provided on one side of the side wall of the purification box 1. A discharge extrusion mechanism 6 is provided at the bottom of the purification box 1. The discharge extrusion mechanism 6 facilitates collecting the fluff and dust together and extruding it.

[0038] In addition, an exhaust port 22 is provided on one side wall of the housing of the exhaust box 2. A suction fan 5 is connected to the exhaust port 22. A plurality of through holes 23 are provided on the bottom wall of the exhaust chamber 21 and above each purification chamber 11. Filter cartridges 81 are provided at the through holes 23. The through holes 23 enable the flow of gas and prevent the outflow of lint and dust.

[0039] Moreover, a plurality of independent intake chambers 42 are provided in the intake box 4, and the intake chambers 42 are all communicated with the purification chamber 11 on one side. A plurality of intake pipes 41 are arranged longitudinally and evenly on the housing of the intake box 4. The intake pipes 41 are all communicated with the intake chambers 42. The intake pipes 41 are used to transport waste gas to the purification box 1.

[0040] Among them, a support frame 82 is provided on the upper surface of the bottom wall of the exhaust chamber 21 and at each through hole 23. A jet mechanism 84 is supported on the support frame 82. The jet mechanism 84 includes a connecting pipe 841. The connecting pipe 841 is arranged in the inner cavity of the filter cartridge 81. Spray pipes 842 are symmetrically connected to both sides of the pipe body of the connecting pipe 841. The spray pipes 842 are communicated with the connecting pipe 841. The top end of the connecting pipe 841 is connected and installed to the air delivery pipe 83. A plurality of spray holes are provided on the pipe body of the spray pipes 842. The spray pipes 842 facilitate the spraying of gas.

[0041] In addition, the discharge extrusion mechanism 6 includes a lint and dust transfer box 62. Conical discharge boxes 61 are arranged longitudinally and evenly on the upper end of the housing of the lint and dust transfer box 62. Each conical discharge box 61 is arranged at the bottom of each purification chamber 11 and communicated with it. The bottom of the conical discharge box 61 is communicated with the inner cavity of the lint and dust transfer box 62. The conical discharge boxes 61 facilitate the fall of lint and dust into the lint and dust transfer box 62.

[0042] Among them, a feeding screw 64 is rotatably arranged in the inner cavity of the lint and dust transfer box 62. A motor 7 is arranged at one end of the housing of the lint and dust transfer box 62. One end of the rod body of the feeding screw 64 extends out of the lint and dust transfer box 62 and is assembled and connected to the output end of the motor 7. The collected lint and dust can be transported to the extrusion box 63 by the rotation of the feeding screw 64 driven by the motor 7.

[0043] Among them, an extrusion box 63 is connected and arranged at the other end of the box body of the fluff and dust transmission box 62 away from the motor 7. The fluff and dust transmission box 62 is communicated with the extrusion box 63. The extrusion box 63 includes a protective cover 631. Symmetric limiting plates 633 are arranged inside the protective cover 631. Connecting rods 634 are symmetrically and rotatably arranged up and down between the two limiting plates 633. A pressure plate 632 is arranged in the middle of the rod body of the connecting rod 634. Connecting plates 636 are symmetrically arranged at both ends of the rod body of the connecting rod 634, and the connecting plates 636 are all arranged on the other side of the limiting plate 633 away from the pressure plate 632. At the other ends of the symmetrically arranged connecting plates 636 up and down away from the connecting rod 634, tension springs 635 are arranged. The top of the tension spring 635 is connected to the upper connecting plate 636, and the bottom of the tension spring 635 is connected to the lower connecting plate 636. The pressure plate 632 can block the fluff and dust, and cooperate with the fluff and dust continuously conveyed by the feeding screw 64, so that the fluff and dust slowly accumulate together and are extruded into a ball by the pressure plate 632.

[0044] In this embodiment, the waste gas with fluff and dust enters the intake cavity 42 from the intake pipe 41. Then, under the pumping of the air extractor 5 at the exhaust port 22, the waste gas with fluff and dust will enter the purification cavity 11 from the intake cavity 42. Then, the waste gas at this time will pass through the filter screen of the filter cartridge 81 and then enter the exhaust box 2. During this process, the fluff and dust in the waste gas will be blocked by the filter screen of the filter cartridge 81, so that the fluff and dust will adhere to the outer surface of the filter screen of the filter cartridge 81. Then, the waste gas without fluff and dust after filtration will enter the exhaust port 22 and be extracted by the air extractor 5. Because of the suction force of the air extractor 5, the fluff and dust adhering to the filter screen of the filter cartridge 81 will not easily fall off from the filter cartridge 81. At this time, it needs to be cleaned regularly.

[0045] When cleaning the fluff and dust accumulated on the filter cartridge 81, first drive the piston rod of the driving cylinder 85 to descend, so that the bottom support plate 86 can descend, so that the filter cartridge 81 descends in the through hole 23, realizing that the filter cartridge 81 is entirely located in the purification cavity 11, thus preventing air from leaking from the through hole 23. At this time, the pulse pump 3 transports compressed air into the air delivery pipe 83, and then the air delivery pipe 83 transmits it to the connecting pipe 841. The connecting pipe 841 transmits the compressed air to the spray pipes 842 on both sides. The compressed air is ejected from each spray hole of the spray pipe 842, and then jets from the inside of the filter cartridge 81. Because the upper through hole 23 is blocked, the suction force of the air extractor 5 cannot affect the purification cavity 11, so that the fluff and dust adhering to the filter screen of the filter cartridge 81 can be easily blown off by the compressed air ejected from the spray pipe 842 and thus fall into the discharging and extruding mechanism 6 below.

[0046] The fluff and dust will first fall into the conical discharge box 61, and then roll and gather into the inner cavity of the fluff and dust transfer box 62. At this time, the feeding screw 64 is driven by the motor 7 to rotate. The feeding screw 64 transfers the fluff and dust to the extrusion box 63 on one side by means of screw transmission.

[0047] Once the fluff and dust are transferred into the extrusion box 63, the fluff and dust will be blocked by the pressing plate 632 that is pressed together, so that it cannot be discharged. As more and more fluff and dust are transferred to the pressing plate 632, the pressing plate 632 cooperates with the feeding of the feeding screw 64 to squeeze and stack the fluff and dust together. Because the upper and lower pressing plates 632 are pulled by the tension spring 635, once the volume of the stacked fluff and dust is large, and the feeding screw 64 can push the upper and lower pressing plates 632, the originally upper and lower pressed pressing plates 632 are separated. The connecting rod 634 rotates on the limiting plates 633 on both sides, and the fluff and dust squeezed into a ball will rush out from the gap between the pressing plates 632. During this process, the tension springs 635 on both sides have a pulling force, so that the upper and lower pressing plates 632 can press the discharged fluff and dust for further extrusion to prevent it from loosening. In this way, the fluff and dust in a ball shape can be better collected and will not easily disperse into the air.

[0048] In the present utility model, a filter and purification unit 8 capable of filtering and purifying fluff and dust is arranged in the purification box 1, and its filter cylinder 81 is movable up and down, so as to change the state of communication between the purification cavity 11 and the exhaust cavity 21. A jet mechanism 84 is arranged in the filter cylinder 81 and cooperates with the pulse pump 3 connected thereto. When it is necessary to clean the fluff and dust attached to the filter cylinder 81, compressed air is blown out by relying on the pulse pump 3 and then ejected from the air injection pipe 842, and the air blown out from the inside of the filter cylinder 81 blows down the fluff and dust on the filter cylinder 81, realizing effective cleaning of the filter cylinder 81. And this cleaning method does not require manual entry into the inside of the purification cavity 11 for cleaning, and such a cleaning method is more convenient and efficient.

[0049] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
