[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0039] Example 1

[0040] like Figure 1-10 A dust exhaust gas treatment system is shown, comprising a treatment box 1, an air inlet pipe 2, an air outlet pipe 3 and a cleaning fan 4. The exhaust gas containing dust is discharged into the treatment box 1 through the air inlet pipe 2, and the gas is discharged outside the treatment box 1 through the air outlet pipe 3;

[0041] A partition plate 7 is provided inside the processing box 1, and the interior of the processing box 1 is divided into a first chamber 8 and a second chamber 9 by the partition plate 7. The air inlet pipe 2 is connected to the side wall of the processing box 1 near the bottom, and the air outlet pipe 3 is connected to the side wall of the processing box 1 near the top. The air inlet pipe 2 and the air outlet pipe 3 are located on opposite sides of the partition plate 7, wherein the areas of the air inlet pipe 2 and the air outlet pipe 3 on both sides of the partition plate 7 are the same;

[0042] By dividing the processing box 1 into a first chamber 8 and a second chamber 9, the exhaust gas containing dust discharged from the air intake pipe 2 can enter the first chamber 8 or the second chamber 9. When a chamber has a lot of dust adsorbed and needs to be cleaned, the exhaust gas in the air intake pipe 2 can be passed into another chamber, thereby not affecting the exhaust gas processing efficiency.

[0043] Two sealing plates 17 are slidably connected to the inner wall of the processing box 1. The two sealing plates 17 are respectively located in the first chamber 8 and the second chamber 9, and the two sealing plates 17 move up and down alternately. The position of the sealing plate 17 corresponds to the position of the air intake pipe 2. The sealing plate 17 is used to seal the air intake pipe 2.

[0044] Refer to the attached Figure 3 and attached Figure 4The position of the middle sealing plate 17 and the partition plate 7, when it is necessary to discharge the exhaust gas containing dust in the intake pipe 2, the two sealing plates 17 will alternately block half of the intake pipe 2, so that the exhaust gas in the intake pipe 2 will only pass into the first chamber 8 or the second chamber 9 at the same time.

[0045] The first chamber 8 and the second chamber 9 are both provided with a filter bag 13 for absorbing dust. The filter bag 13 is cylindrically arranged, and a cleaning shaft 18 is arranged at the center thereof. Two cleaning pipes 5 are connected to the blowing port of the cleaning fan 4. The cleaning fan 4 can blow air into the cleaning pipes 5. The two cleaning pipes 5 extend into the first chamber 8 and the second chamber 9 respectively. The cleaning pipe 5 is located at one end of the treatment box 1 and is directly opposite to the top of the filter bag 13, and a sealing port 39 for blocking is opened on the side wall thereof. It should be noted that during the exhaust gas treatment process, the cleaning fan 4 is always turned on, and can generate wind force during this process;

[0046] Among them, the filter bag 13 is a prior art, and its function is to absorb dust in the exhaust gas. In the above method, when the filter bag 13 has absorbed too much dust and needs to be cleaned, when the filter bag 13 absorbs too much dust, wind is generated by the cleaning fan 4, and the wind is transmitted to the processing box 1 through the cleaning pipe 5, so as to blow the filter bag that needs to be removed and blow off the dust on the surface, so as to facilitate the subsequent alternating use of the first chamber 8 and the second chamber 9.

[0047] A driving shaft 6 is rotatably connected to the center of the top of the processing box 1, and a partition rod 14 is fixedly connected to the bottom end of the driving shaft 6. An opening and closing mechanism is provided on the partition rod 14, which is used to control the gas supply of the air inlet pipe 2 and the blowing of the cleaning pipe 5.

[0048] One end of the drive shaft 6 located in the processing box 1 is fixedly connected to the partition rod 14, and the partition rod 14 spans the first chamber 8 and the second chamber 9. The side walls on both sides of the partition plate 7 are slidably connected to the moving rods 15. Figure 4 Two corresponding installation openings are provided on the partition rod body 14, and the moving rod 15 and the installation openings can slide relative to each other, and two symmetrically arranged blocking circular plates 40 are fixedly connected to the partition rod body 14, and the blocking circular plates 40 block the blowing in the cleaning pipe 5 through the sealing opening 39; the moving rod 15 and the sealing plate 17 are connected by a connecting rod 16, and the two ends of the connecting rod 16 are respectively rotatably connected with the moving rod 15 and the sealing plate 17.

[0049] When the driving shaft 6 rotates, the partition rod body 14 is driven to rotate, and the partition rod body 14 causes the two moving rods 15 to move in opposite directions under the action of the mounting opening. The moving rod 15 moving toward the direction of the air intake pipe 2 will block the discharge port of the air intake pipe 2 of the corresponding chamber, and synchronously, the blocking circular plate 40 will also rotate with the corresponding moving rod 15, and when rotating, the cleaning pipe 5 of the blocked chamber will be opened.

[0050] For example, when the first chamber 8 is in the process of dust treatment, the air inlet duct 2 in the first chamber 8 is open, while the air inlet duct 2 in the second chamber 9 is blocked by the sealing plate 17, and the corresponding blocking circular plate 40 blocks the cleaning duct 5 extending into the first chamber 8. A large amount of dust is adsorbed on the filter bag 13 in the second chamber 9, and at this time, the blocking circular plate 40 in the second chamber 9 is located outside the corresponding cleaning duct 5. The wind force generated by the cleaning fan 4 will blow the filter bag 13 in the second chamber 9 through the opened cleaning duct 5, so as to clean the dust adsorbed on the surface of the filter bag 13.

[0051] The top end of the driving shaft 6 is externally connected to a driving source, and the driving source drives the driving shaft 6 to rotate. The rotation of the driving shaft 6 controls the partial sealing of the air inlet duct 2 and the ventilation of the cleaning duct 5 in any chamber.

[0052] Therefore, the cleaning fan 4 is in a normally open state during the exhaust gas treatment process, and the driving source is controlled by the monitoring device to rotate the driving shaft 6, thereby controlling the rotation of the partition rod body 14, thereby controlling the opening and closing states of the two chambers. No manual operation is required, the operating burden is reduced, and errors are less likely to occur.

[0053] In this method, the driving source can monitor the filter bags 13 in the two chambers by setting a monitoring device. When the surface of the filter bags 13 adsorbs a sufficient amount of dust, the driving source controls the driving shaft 6 to rotate, thereby controlling the rotation of the partition rod 14. When the partition rod 14 rotates, the sealing plate 17 of the chamber corresponding to the filter bag 13 adsorbed with dust will move down. At this time, the filter bag 13 in the other chamber is also cleaned, and the sealing plate 17 of the cleaned chamber will move up, and the exhaust gas will pass into the chamber. In this way, the exhaust gas can be continuously processed alternately through the two chambers.

[0054] Example 2

[0055] This embodiment expands the cleaning steps of the filter bag 13 in the first embodiment, and improves the efficiency of handling dust on the surface of the filter bag 13 by providing a pushing mechanism.

[0056] The cleaning shaft 18 is provided with a pushing mechanism for cleaning dust on the surface of the filter bag 13 .

[0057] The pushing mechanism includes a blowing fan blade 28 fixedly connected to the top side wall of the cleaning shaft 18, and the blowing fan blade 28 drives the cleaning shaft 18 to rotate through the wind in the cleaning pipe 5. A guide rod 30 is provided on one side of the cleaning shaft 18, and the guide rod 30 is set in a telescopic manner. A power disk 19 and a pushing disk 20 are provided on the guide rod 30. The cleaning shaft 18 is located at the center of the power disk 19 and the pushing disk 20. The power disk 19 and the pushing disk 20 can both slide along the setting direction of the guide rod 30. The outer wall sleeve of the guide rod 30 is provided with a mounting spring 31. The mounting spring 31 is used for resetting the power disk 19 after it moves down. The power disk 19 and the pushing disk 20 are connected by a plurality of connecting columns. The pushing disk 20 is located directly above the power disk 19, that is, the power disk 19 and the pushing disk 20 are fixed to each other.

[0058] When there is no wind, the power disc 19 will be located near the upper end of the filter bag 13 under the action of the mounting spring 31. When the power disc 19 moves up or down, the guide rod 30 will be extended or contracted.

[0059] A sliding recess 21 is provided on the power disk 19, and the cleaning shaft 18 is located in the sliding recess 21. An adapter block 22 is slidably connected in the sliding recess 21. An external thread 24 is provided on the outer wall of the cleaning shaft 18, and an internal thread 23 is provided on the side of the adapter block 22 opposite to the cleaning shaft 18, wherein the internal thread 23 and the external thread 24 are adapted to each other;

[0060] A wind receiving block 26 is slidably connected to the power disk 19 in the vertical direction. A return spring 25 is provided between the wind receiving block 26 and the power disk 19. The wind receiving block 26 is connected to the adapter block 22 through an adapter rod 27. When the wind receiving block 26 is subjected to wind force, the adapter block 22 is pushed by the adapter rod 27 to move in the direction of the cleaning axis 18.

[0061] When the surface of the filter bag 13 is cleaned of dust, the wind in the cleaning duct 5 will blow in the direction of the cleaning shaft 18. In the process of blowing the dust inside and outside the filter bag 13, the wind will drive the plurality of blowing fan blades 28 to rotate, thereby causing the cleaning shaft 18 to rotate. At the same time, the wind will also exert a downward force on the wind receiving block 26 through the vent holes, wherein the top of the wind receiving block 26 is set in a concave arc shape, the purpose of which is to increase the wind receiving area. The wind receiving block 26 will move downward under the action of the wind force, so that the reset spring 25 is compressed, and the adapter block 22 will also move in the direction of the cleaning shaft 18 as the wind receiving block 26 moves downward. Specifically, the downward movement of the wind receiving block 26 will be driven by the adapter rod 27, causing the adapter block 22 to move. When the adapter block 22 contacts the cleaning shaft 18, the internal thread 23 contacts the external thread 24. At this time, the cleaning shaft 18 is in a rotating state, and the power disk 19 is driven to move downward through the external thread 24, and the push disk 20 is also driven to move downward synchronously.

[0062] The push-off disk 20 is provided with a plurality of ventilation holes for wind to blow downward, and a plurality of push-off blocks 32 are elastically connected to the push-off disk 20. A wire groove 35 is provided on the outer wall of the cleaning shaft 18. The push-off disk 20 is rotatably connected with an active disk 33, which is located on the outer side of the cleaning shaft 18. The active disk 33 is fixedly connected to a wire block 36, and the wire block 36 can slide in the wire groove 35.

[0063] When the cleaning shaft 18 rotates, the active disk 33 rotates with the rotation of the cleaning shaft 18 through the cooperation of the wire block 36 and the wire groove 35. The active disk 33 and the push-off disk 20 can rotate relative to each other, and the active disk 33 is driven to move downward during the downward movement of the push-off disk 20. At this time, the active disk 33 can rotate at the same time during the downward movement.

[0064] Two symmetrically arranged pushing rods 34 are fixedly connected to the active disk 33. In the rotation direction of the pushing rods 34, the opposing sides of the pushing rods 34 and the pushing blocks 32 are both arranged in an inclined manner.

[0065] During the downward movement of the active disk 33, the push rod 34 is driven to rotate, and at the same time, the push rod 34 and the push block 32 are contacted with the inclined surface to make the push block 32 move to the outside of the push disk 20, thereby making the push block 32 contact with the surface of the filter bag 13, increasing its vibration, and being able to push to the dead corner that the wind cannot reach. The cleaning effect of dust can be improved, and this method can clean the inside and outside of the filter bag 13.

[0066] A wind receiving groove 37 is provided in the cleaning shaft 18 , and a plurality of blowing holes 38 are provided between the wind receiving groove 37 and the outer wall of the cleaning shaft 18 . The blowing holes 38 are arranged obliquely downward, and a wind receiving funnel 29 is fixedly connected to the top of the cleaning shaft 18 .

[0067] Through the provided blowing holes 38 , the wind blown out of the cleaning pipe 5 will be blown through the blowing holes 38 , thereby ensuring that the wind receiving block 26 can be kept in a fixed position during the downward movement of the power disk 19 , thereby ensuring the contact between the internal thread 23 and the external thread 24 .

[0068] After cleaning is completed, the partition rod 14 will rotate to close the cleaning pipe 5. At this time, the wind receiving block 26 is no longer pushed by the wind. At this time, the internal thread 23 and the external thread 24 will be separated from each other, and then the power disk 19 will be reset under the action of the installation spring 31, which is convenient for the subsequent cleaning process.

[0069] The air outlet end of the cleaning pipe 5 is fixedly connected with a blower 12, and the diameter of the bottom end of the blower 12 is larger than the diameter of the filter bag 13, so that air can be blown to both the inside and outside of the filter bag 13, which facilitates the separation of dust from the filter bag 13. The inner bottoms of the first chamber 8 and the second chamber 9 are both arranged in an arc shape, and a discharge pipe 10 for discharging dust is arranged at the lowest end, and the dust at the bottom end of the two discharge pipes 10 is gathered in the discharge pipe 11 and discharged.

[0070] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
