Description

Technical Field

[0001] The invention relates to the technical field of dust exhaust gas filtration and separation, and in particular to a dust exhaust gas filtration and separation treatment device and method. Background Art

[0002] With the development of industrialization and urbanization, the dust and exhaust gas pollution problems generated in industrial production, construction sites, transportation and other activities are becoming increasingly serious. Dust and exhaust gas contain a large amount of harmful substances, such as heavy metals, fine particulate matter, organic volatile compounds, etc. These substances pose a serious threat to human health. Therefore, in order to protect the health and safety of workers and the public, effective dust and exhaust gas filtration and separation equipment is needed to reduce the release of these harmful substances.

[0003] The existing dust filtering and processing equipment is generally composed of a filter chamber, a filter barrel, an air inlet and an exhaust port. When the exhaust gas is processed, the large and small dust in the exhaust gas can be filtered through the coordinated cooperation of the air inlet, outlet pipe and filter barrel. The dust and gas can be separated by setting the filter barrel. After the dust filtering and processing equipment is used for a long time, a lot of dust will accumulate on the surface of the filter barrel, which is easy to cause blockage on its surface, resulting in increased air flow resistance. If it is not cleaned in time, it is easy to affect the effect of subsequent filtration, and thus the dust exhaust gas cannot be effectively separated. In the prior art, air is blown into the interior of the filter barrel from the mouth through an air pulse blowing pipe to blow off the dust adsorbed on the outer surface. Since the airflow diffuses outward from a point, the cleaning effect is uneven, resulting in different cleaning degrees of different parts of the filter barrel, and it is impossible to effectively clean all the dust on the entire filter barrel surface, especially the dust at the bottom of the filter barrel and the dust deep in the filter barrel.

[0004] Therefore, the present invention proposes a dust exhaust gas filtering and separation treatment device and method to improve the deficiencies of the traditional technology. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a dust exhaust gas filtration separation treatment device and method, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a dust exhaust gas filtering and separation treatment equipment, including a dust collector, the top of the dust collector is penetrated by an auxiliary tube which is rotatably connected, the bottom of the auxiliary tube is located at one end of the dust collector and is rotatably connected to a filter barrel, the bottom end of the filter barrel is fixedly connected to an outlet pipe, the outlet pipe passes through the interior of the dust collector, the interior of the auxiliary tube is provided with an auxiliary component for uniformly cleaning the interior of the filter barrel, and the interior of the dust collector is provided with a collecting component for auxiliary cleaning.

[0007] Preferably, the auxiliary component includes a spiral groove, which is opened through the outer surface of the auxiliary cylinder, the interior of the spiral groove is slidably connected to a first cylinder, the end of the first cylinder away from the spiral groove is slidably connected to a vertical slide, the interior of the auxiliary cylinder is movably connected to an inner ring cylinder, and the bottom of the inner ring cylinder is fixedly connected to an auxiliary scraper.

[0008] Preferably, the outer surface of the first cylinder is fixedly connected to the top of the inner ring tube, the bottom of the vertical slide is fixedly connected to the upper surface of the filter barrel, and the inner wall dimensions of the inner ring tube and the auxiliary scraper are adapted to the outer wall dimensions of the filter barrel.

[0009] Preferably, the top of the auxiliary cylinder is fixedly connected to a motor, the inner wall of the auxiliary cylinder is fixedly connected to a rotating cylinder, the outer surface of the rotating cylinder is penetrated by a vertical groove, the interior of the vertical groove is slidably connected to a second cylinder, the interior of the rotating cylinder is movably connected to a threaded column, and the bottom of the threaded column is fixedly connected to a diversion pipe.

[0010] Preferably, one end of the second cylinder located in the rotating cylinder is fixedly connected to the outer surface of the threaded column, the threaded column is threadedly connected to the top of the filter barrel, the threaded column passes through the interior of the filter barrel, the diversion pipe is located inside the filter barrel, the interior of the threaded column is connected to the interior of the diversion pipe, and the interior of the threaded column is fixedly connected to a pulse valve.

[0011] Preferably, the collecting assembly includes a fixed annular plate, the outer surface of which is fixedly connected to the inner wall of the dust collector, the inner wall of the dust collector is fixedly connected to a driving cylinder, the top of the driving cylinder is fixedly connected to a circular scraper, the inner wall of the circular scraper is provided with a sliding groove, the inner wall of the sliding groove is fixedly connected to a reset spring, and the interior of the sliding groove is slidably connected to an arc scraper.

[0012] Preferably, the inner wall of the annular scraper is provided with a circular array of sliding grooves, circular arc scrapers and return springs, and the fixed annular plate and the auxiliary scraper are both provided with inclined surfaces.

[0013] The dust waste gas filtering and separation treatment method comprises the following steps:

[0014] Step 1: The dust-laden gas enters through the air inlet of the dust collector. During the air intake process, the coarser dust particles will fall directly into the ash hopper under the action of gravity and inertia, achieving preliminary separation;

[0015] Step 2: Fine dust particles continue to enter the filter bag chamber with the air flow, ready for further filtering. In the process of entering the filter bag chamber, the dust particles are captured by the fiber layer on the filter barrel and attached to the outer surface of the filter barrel. The clean gas filtered by the filter barrel is discharged from the outlet pipe;

[0016] Step 3: As the dust removal process continues, dust on the surface of the filter barrel will gradually accumulate. When the dust accumulates to a certain extent, start the auxiliary components and pulse valve to allow compressed air to be evenly sprayed into the filter barrel through the movement and rotation of the threaded column and the shunt pipe, blow out the dust attached to the filter holes, and clean the surface of the filter barrel through the movement of the auxiliary scraper;

[0017] Step 4: Start the collection component to clean the dust adhered to the surface of the auxiliary scraper and clean it by itself. The cleaned dust falls to the bottom of the dust collector by itself. After cleaning, the dust is discharged by the ash discharge valve and collected in the ash hopper.

[0018] The dust exhaust gas filtering and separation treatment equipment provided by the present invention has the following beneficial effects:

[0019] 1. Through the coordinated use of the threaded column, the second cylinder and the diverter pipe, the gas can be blown out evenly from the diverter pipe during air pulse blowing. The diverter pipe can evenly distribute the gas to multiple outlets to ensure that the flow rate received by each branch is consistent. The threaded column is then used to make the diverter pipe rotate and move inside the filter barrel for blowing, which can ensure that every part of the filter barrel is evenly cleaned and the blind spot of cleaning is reduced. The coordination of rotation and movement makes the blowing more efficient, which can remove more dust and particles and improve the cleaning efficiency. Through rotation and movement, the airflow can act on the surface of the filter barrel at different angles and directions to enhance the cleaning power, especially for corners and gaps that are difficult to clean.

[0020] 2. Through the coordinated use of spiral grooves, vertical slide plates, inner ring barrels and auxiliary scrapers, the auxiliary scrapers can be moved downward on the surface of the filter barrel while the air pulses in the filter barrel are being pulsed to further clean the dust on the surface of the filter barrel. The air pulses can help loosen and blow off the dust inside the filter holes of the filter barrel, while the movement of the auxiliary scrapers can help remove the residual dust on the surface, thereby achieving a more thorough cleaning effect. By cleaning the dust on the surface of the filter barrel, the blockage of the filter medium can be reduced, the filtration efficiency can be improved, and the replacement frequency of the filter medium can be reduced. By arranging the shunt pipe below the auxiliary scraper, the airflow blown out by the shunt pipe can effectively loosen the dust in the filter holes, and the auxiliary scraper follows closely to scrape off the dust. This combination ensures deep cleaning inside the filter holes. The inner ring barrel blocks the filter holes after cleaning, which can prevent dust from entering the filter holes again, thereby protecting the filter holes from further contamination.

[0021] 3. Through the coordinated use of the ring scraper, the arc scraper and the return spring, the dust adhering to the surface of the auxiliary scraper can be scraped off to the bottom of the dust collector for collection, so as to prevent excessive dust on the surface of the auxiliary scraper from affecting the secondary use. The dust is regularly scraped off and collected to keep the auxiliary scraper clean, ensuring that it always has the best scraping effect. Through the use of the return spring, the arc scraper can adapt to the inclined surface of the auxiliary scraper and always maintain contact with the auxiliary scraper, reducing incomplete cleaning caused by poor contact. The return spring makes the arc scraper exert pressure on the auxiliary scraper to improve the cleaning effect of the auxiliary scraper. When the arc scraper slides in the chute, the chute limits the arc scraper to push off the dust on the surface of the arc scraper, thereby realizing self-cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 1

[0038] The auxiliary component 5 includes a spiral groove 51, which penetrates and is opened on the outer surface of the auxiliary cylinder 4.

The inner wall dimensions of the inner ring cylinder 54 and the auxiliary scraper 55 are adapted to the outer wall dimensions of the filter barrel 2. While the air pulse in the filter barrel 2 is being pulsed, the auxiliary scraper 55 is moved downward on the surface of the filter barrel 2 to further clean the dust on the surface of the filter barrel 2. The air pulse can help loosen and blow off the dust inside the filter holes of the filter barrel 2, and the movement of the auxiliary scraper 55 helps to remove residual dust on the surface, thereby achieving a more thorough cleaning effect.

[0039] A motor is fixedly connected to the top of the auxiliary cylinder 4, and a rotating cylinder 56 is fixedly connected to the inner wall of the auxiliary cylinder 4. A vertical groove 57 is penetrated through the outer surface of the rotating cylinder 56, and a second cylinder 59 is slidably connected inside the vertical groove 57. A threaded column 58 is movably connected inside the rotating cylinder 56, and a shunt pipe 510 is fixedly connected to the bottom of the threaded column 58. One end of the second cylinder 59 located in the rotating cylinder 56 is fixedly connected to the outer surface of the threaded column 58, and the threaded column 58 is threadedly connected to the top of the filter barrel 2.

The interior of the threaded column 58 is connected to the interior of the shunt pipe 510, and a pulse valve is fixedly connected to the interior of the threaded column 58. By arranging the shunt pipe 510 below the auxiliary scraper 55, the airflow blown out by the shunt pipe 510 can effectively loosen the dust in the filter hole, and the auxiliary scraper 55 follows closely to scrape off the dust. This combination ensures deep cleaning of the inside of the filter hole.

[0040] Compared with the prior art, the device can realize uniform blowing of gas from the diverter pipe 510 during air pulse blowing, ensuring that the flow received by each branch is consistent, ensuring that each part of the filter barrel 2 is evenly cleaned, reducing cleaning blind spots, and making the blowing more efficient through the coordination of the rotation and movement of the diverter pipe 510, which can remove more dust and particles and improve cleaning efficiency.

The use of the reset spring 65 can make the arc scraper 64 adapt to the inclined surface of the auxiliary scraper 55 and always maintain contact with the auxiliary scraper 55, reducing incomplete cleaning caused by poor contact. The reset spring 65 makes the arc scraper 64 apply pressure to the auxiliary scraper 55 to improve the cleaning effect of the auxiliary scraper 55. When the arc scraper 64 slides in the slide groove 63, the slide groove 63 limits the arc scraper 64 to push off the dust on the surface of the arc scraper 64, thereby realizing self-cleaning.

[0042] Embodiment 2

[0043] The dust waste gas filtering and separation treatment method comprises the following steps:

[0044] Step 1: The dust-laden gas enters through the air inlet of the dust collector 1. During the air intake process, the coarser dust particles will fall directly into the ash hopper under the action of gravity and inertia, achieving preliminary separation;

[0045] Step 2: Fine dust particles continue to enter the filter bag chamber with the air flow, ready for further filtering. In the process of entering the filter bag chamber, the dust particles are captured by the fiber layer on the filter barrel 2 and attached to the outer surface of the filter barrel 2. The clean gas filtered by the filter barrel 2 is discharged from the outlet pipe 3;

[0046] Step 3: As the dust removal process continues, dust on the surface of the filter barrel 2 will gradually accumulate. When the dust accumulates to a certain extent, the auxiliary component 5 and the pulse valve are started to allow the compressed air to be evenly sprayed into the filter barrel 2 through the movement and rotation of the threaded column 58 and the shunt pipe 510, and the dust attached to the filter holes is blown out and the surface of the filter barrel 2 is cleaned through the movement of the auxiliary scraper 55;

[0047] Step 4: Start the collecting assembly 6 to clean the dust adhered to the surface of the auxiliary scraper 55 while self-cleaning. The cleaned dust falls into the bottom of the dust collector 1 by itself. After the cleaning is completed, the dust is discharged by the dust discharge valve and collected in the ash hopper.

[0048] The following is the entire working process and working principle of the above embodiment:

[0049] First, the dust-laden gas enters through the air inlet of the dust collector 1. During the air intake process, coarser dust particles will fall directly into the ash hopper under the action of gravity and inertia to achieve preliminary separation, and the fine dust particles will continue to enter the interior of the filter barrel 2 with the air flow, ready for further filtering treatment. In the process of entering the interior of the filter barrel 2, the dust particles are captured by the filter barrel 2 and attached to the outer surface of the filter barrel 2. The clean gas filtered by the filter barrel 2 is discharged from the outlet pipe 3. As the dust removal process continues, the dust on the surface of the filter barrel 2 will gradually accumulate. When the dust accumulates to a certain extent, the operator starts the motor and the pulse valve to blow the compressed air out from the inside of the threaded column 58 and the inside of the shunt pipe 510. The shunt pipe 510 can evenly distribute the gas to multiple outlets to ensure that the flow rate received by each branch is the same. The motor starts to drive the auxiliary cylinder 4 to rotate, and the rotation of the auxiliary cylinder 4 drives the rotating cylinder 56 to rotate, and the rotation of the rotating cylinder 56 drives the second cylinder 59 to rotate, and the rotation of the second cylinder 59 drives the threaded column 58 to rotate. Since the threaded column 58 is threadedly connected to the filter barrel 2, the rotation of the threaded column 58 drives the diverter pipe 510 to rotate and move downward at the same time. The threaded column 58 makes the diverter pipe 510 rotate and move inside the filter barrel 2 to blow air, which can ensure that every part of the filter barrel 2 is evenly cleaned and the blind spots of cleaning are reduced. The coordination of rotation and movement makes the blowing more efficient, which can remove more dust and particles and improve the cleaning efficiency. Through rotation and movement, the airflow can act on the surface of the filter barrel 2 at different angles and directions, thereby enhancing the cleaning power, especially for corners and gaps that are difficult to clean.

[0050] At the same time, the auxiliary cylinder 4 rotates to drive the first cylinder 52 to slide inside the spiral groove 51. Since the first cylinder 52 is restricted by the vertical slide plate 53, the auxiliary cylinder 4 rotates and drives the first cylinder 52 to move downward. The downward movement of the first cylinder 52 drives the inner ring cylinder 54 to move downward. The downward movement of the inner ring cylinder 54 drives the auxiliary scraper 55 to move downward. Since the inner wall dimensions of the inner ring cylinder 54 and the auxiliary scraper 55 are compatible with the outer wall dimensions of the filter barrel 2, the auxiliary scraper 55 cleans the surface of the filter barrel 2 when moving downward. The movement of the auxiliary scraper 55 helps to remove residual dust on the surface, thereby achieving a more thorough cleaning effect. By cleaning the dust on the surface of the filter barrel 2, the blockage of the filter medium can be reduced, the filtering efficiency can be improved, and the replacement frequency of the filter medium can be reduced. The inner ring cylinder 54 follows the movement of the auxiliary scraper 55 to block the filter holes after cleaning, which can prevent dust from entering the filter holes again, thereby protecting the filter holes from further contamination.

[0051] When the auxiliary scraper 55 moves downward to the bottom of the fixed annular plate 61, and the inclined surfaces of the auxiliary scraper 55 and the fixed annular plate 61 are in the same plane, the operator starts the driving cylinder 66, and the driving cylinder 66 contracts to drive the annular scraper 62 to move downward, and the annular scraper 62 moves downward to drive the arc scraper 64 and the return spring 65 to move downward. Due to the inclined surface setting of the fixed annular plate 61 and the auxiliary scraper 55, the squeezing force on the return spring 65 during the movement of the annular scraper 62 gradually decreases, and the return spring 65 returns and stretches to drive the arc scraper 64 to move inside the slide groove 63, and the arc scraper 64 moves to be close to the surface of the auxiliary scraper 55, and the arc scraper 64 moves downward to push the auxiliary scraper 55. The dust on the surface of the auxiliary scraper 55 is cleaned, and the dust adhered to the surface of the auxiliary scraper 55 is scraped off to the bottom of the dust collector 1 for collection, so as to prevent excessive dust on the surface of the auxiliary scraper 55 from affecting the secondary use. The dust is regularly scraped off and collected to keep the auxiliary scraper 55 clean, so as to ensure that it always has the best scraping effect. When the arc scraper 64 is cleaned, the cylinder 66 is driven to extend and drive the annular scraper 62 to move upward. The annular scraper 62 moves upward and the arc scraper 64 squeezes the reset spring 65. Since the sizes of the slide groove 63 and the arc scraper 64 are adapted, the limit of the slide groove 63 makes the dust on the surface of the arc scraper 64 be pushed off when the arc scraper 64 moves into the inside of the slide groove 63, thereby realizing self-cleaning.
