[0002] At industrial construction sites, engineering operations will generate dust and powder. In order to ensure the cleanliness of the working environment and ensure operational safety, corresponding dust removal facilities need to be set up on site to clean the dust in the air. Existing dust removal equipment generally filters dust through filters, but traditional maintenance of filters mostly involves replacing filters for cleaning, which requires long downtime. At the same time, there is a lack of dedicated cleaning equipment for the removed filters, which results in secondary dust generation during cleaning, affecting the dust removal process at the industrial construction site. Summary of the Invention

[0008] Preferably, a tapered diameter section for performing secondary acceleration on the jet gas is provided in the middle of the inner hole of the dust collecting tube of the present invention, so as to maintain the jet gas flow rate in the lower area of ​​the dust collecting tube.

[0009] Preferably, the lifting butt joint of the present invention is connected to the external air source through an air distribution pipe. The air distribution pipe is arranged on the top of the filter box and is located between the first filter plate 6 and the second filter plate. A vibration component for cooperating with the corresponding filter plate surface is provided on one side of the air distribution pipe close to the first filter plate and the second filter plate.

[0010] Preferably, the lower ends of the first filter plate and the second filter plate of the present invention are fixedly connected to the bottom of the filter box, and the upper ends are movably connected to the top of the filter box.

The side walls of the mounting grooves opposite to the vibration components are provided with elastic components for elastically abutting the corresponding filter plate sides. The elastic components enable the filter plates to reciprocate after being struck by the vibration components.

[0011] The present invention discloses a manufacturing method for the above-mentioned industrial dust removal and filtering structure, wherein a first filter plate and a second filter plate are selected according to the dust particle situation of the dust removal environment, the openings on the plate surfaces of the first filter plate and the second filter plate meet the dust removal needs of the industrial environment, the first filter plate and the second filter plate are installed in the filter box, the lower ends of the first filter plate and the second filter plate are embedded in the card slots opened in the filter box, and are kept relatively fixed with the filter box; a dust collecting pipe is arranged between the first filter plate and the second filter plate, an elastic component is installed on the side of the first filter plate and the second filter plate away from the dust collecting pipe, the corresponding filter plate is connected to the filter box, and the length of the dust collecting pipe is determined according to the length of the first filter plate and the second filter plate The height of the two filter plates is designed so that the length of the dust collecting tube covers the filtration area of ​​the first filter plate and the second filter plate.

[0012] Preferably, the gas flow rate at the end of the dust collecting tube of the present invention is simulated by simulation software. When the external gas source pressure is constant, a tapered diameter section is set in the dust collecting tube to perform secondary acceleration on the jet gas to maintain the air flow velocity at the end of the dust collecting tube.

[0013] The present invention discloses a dust removal system, which uses the above-mentioned industrial dust removal and filtering structure to perform dust removal operations at industrial sites.

[0014] Beneficial effects: The industrial dust removal filter structure, manufacturing method and dust removal system disclosed in the present invention have the following beneficial effects: 1. The present invention provides a cleaning mechanism in the filter box to clean the particulate matter attached to the particle filter assembly, and collects the fallen particulate dust through the dust collection assembly so that it can smoothly enter the dust box and be discharged from the dust outlet for dust collection. On the one hand, there is no need to disassemble the filter structure, and at the same time, the dust collection assembly is used to collect dust, which can also avoid the dust escape caused by the conventional cleaning method through ventilation, thereby realizing rapid cleaning of the dust on the filter structure.

[0015] 2. The particle filtering assembly of the present invention adopts a first filter plate and a second filter plate with two plates arranged opposite to each other. By designing different filter apertures, the filtering requirements of dust with different particle sizes at the work site can be met. At the same time, the second filter area of ​​the second filter plate and the filter area of ​​the first filter plate are staggered with each other. The second filter plate is provided with a buffer groove at a position corresponding to the first filter area, which can block the airflow and slow it down. The dust particles in the gas can fall directly into the dust box under the action of gravity, thereby reducing the filtering pressure of the second filter plate and improving the dust removal effect.

[0016] 3. The dust collecting component of the present invention uses a dust collecting tube with holes in the side wall, and uses the negative pressure generated by the high-speed jet airflow to form a negative pressure area around the dust collecting tube that is different from other areas. Dust can be gathered to the dust collecting tube under the action of negative pressure, and part of it can enter the dust collecting tube through the negative pressure holes and be discharged by the airflow. Even if the dust does not enter, it will not escape, but will gradually gather to the dust box below for discharge. This method can facilitate the cleaning of the filter plate, avoid the phenomenon of secondary dust, and improve the cleaning and maintenance efficiency of the filter plate.

[0017] 4. A tapered diameter section is provided in the dust collecting tube of the present invention, which can perform secondary acceleration on the jet gas. Therefore, when the length of the dust collecting tube is long, the negative pressure adsorption force on the dust generated by the dust collecting tube can be ensured without increasing the pressure demand for the external gas source, thereby ensuring the cleaning effect.

[0018] 5. The first filter plate and the second filter plate of the present invention are both fixed relatively to the filter box at the bottom, while the upper end is movably fitted with the filter box through an elastic component. In combination with the vibration component, the dust removal effect of the vibration knocking can be amplified, thereby improving the cleaning efficiency and effect.

[0019] 6. The industrial dust removal and filtering structure manufacturing method of the present invention can design the corresponding dust removal and filtering structure based on the working environment of the industrial site. At the same time, it can be used with the dust collecting pipe to clean the dust of filter structures of different sizes in different environments, and has wide adaptability.

Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and is not intended to be limiting. On the contrary, the following description provides a convenient illustration of exemplary embodiments for implementing the present disclosure. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made within the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0023] like Figures 1-4As shown, the present invention discloses an industrial dust removal and filtering structure, including a filter box 1, the filter box 1 is provided with an air inlet end 2 and an exhaust end 3, and a particle filter assembly for filtering the dust-laden gas is provided inside the filter box 1. The dust-laden gas enters from the air inlet end 2, is filtered by the particle filter assembly, and is discharged from the exhaust end 3; a cleaning mechanism for cleaning attached particulate matter is provided on the particle filter assembly, and the cleaning mechanism includes a dust box 4 arranged below the particle filter assembly, and a dust outlet 5 is provided at the bottom of the dust box 4 for switching the communication state with the outside of the filter box 1, and a dust collecting assembly for assisting dust to gather to the dust box during dust removal is correspondingly provided in the dust box 4.

[0024] The particle filtering assembly of the present invention includes a first filter plate 6 and a second filter plate 7 with opposite plate surfaces. The plate surfaces of the first filter plate 6 and the second filter plate 7 are arranged perpendicular to the air intake direction. Corresponding arrangements are made on the first filter plate 6 and the second filter plate 7 for airflow to pass through a first filter area 8 and a second filter area 9. The first filter area 8 and the second filter area 9 are staggered. The second filter plate 7 is provided with a buffer groove 10 at a position corresponding to the first filter area 8. The concave surface of the buffer groove 10 faces the air intake direction, and the edge of the buffer groove 10 is smoothly transitioned to the adjacent second filter area 9 through an arc structure.

[0025] In an embodiment of the present invention, Figure 1 As shown, the exhaust section 3 of the filter box 1 is connected to the fan, and the air intake power is provided by the fan, so that the external dust-laden gas can enter the filter box 1 from the air inlet end 2, and the particulate dust in the gas is removed by the particle filter assembly formed by the first filter plate 6 and the second filter plate 7. The filter apertures of the first filter plate 6 and the second filter plate 7 can be selected based on needs, and the same aperture or an aperture with a larger aperture in the front and a smaller aperture in the back along the air inlet direction can be used; the filtered dust part adheres to the surface of the filter plate, and the larger dust particles fall into the dust box 4 under the action of gravity. During the normal dust removal process, the dust box 4 is in a closed state with the outside, and the dust outlet 5 is closed, so that the dust can be temporarily stored in the dust box 4; when the filter plate needs to be cleaned, the dust outlet 5 is opened, and the dust generated by cleaning is discharged from the dust outlet 5. A dust collecting bag can be set at the dust outlet 5 to reduce the escape of dust particles when they are discharged.

[0026] To facilitate dust collection, Figure 3 and Figure 4 As shown, the dust collecting assembly of the present invention includes a dust collecting tube 11 arranged in the dust box 4, and the side wall of the dust collecting tube 11 is symmetrically provided with negative pressure holes 12. A lifting docking joint 13 corresponding to the end of the dust collecting tube 11 is correspondingly provided on the filter box 1, and the lifting docking joint 13 is connected to the external air source. A jet hole 14 is correspondingly opened at the matching position of the lifting docking joint 13 and the dust collecting tube 11.

[0027] When the particle filter assembly is used for dust cleaning in the present invention, the lifting docking joint 13 is docked with the dust collecting tube 11, and the gas from the external air source enters the dust collecting tube 11 from the jet hole 14. The high-speed flow of the jet gas generates negative pressure, and the negative pressure hole 12 opened on the side wall of the dust collecting tube 11 generates an adsorption force to collect the dust, so that the dust gathers to the dust box 4 and is discharged from the dust outlet 5.

[0028] In the case where the dust collecting tube 11 requires a longer length, a larger gas source pressure is required to ensure that the jet gas can still generate sufficient negative pressure suction at the end of the dust collecting tube 11, which will result in greater energy consumption. In order to further improve the dust collection effect, a tapered diameter section 15 for secondary acceleration of the jet gas is provided in the middle part of the inner hole of the dust collecting tube 11 of the present invention. A single group or multiple groups can be provided according to needs to maintain the jet gas flow rate in the lower area of ​​the dust collecting tube 11.

[0029] The lifting docking joint 13 of the present invention is connected to the external air source through the air distribution pipe 16, and at the same time realizes the air supply to multiple dust collection pipes 11. The air distribution pipe 16 is arranged at the top of the filter box 1 and is located between the first filter plate 6 and the second filter plate 7. The air distribution pipe 16 is driven to move in the filter box 1 by an automatic lifting structure such as a lifting cylinder to realize the docking of the lifting docking joint 13 with the dust collection pipe 11. A vibration component for cooperating with the corresponding filter plate surface is provided on the side of the air distribution pipe 16 close to the first filter plate 6 and the second filter plate 7. The vibration component can use a knocking cylinder or a cam to intermittently knock the filter plate to generate vibration so that dust can be separated from the filter plate.

[0030] In order to further improve the dust cleaning effect of the filter plate, the lower ends of the first filter plate 6 and the second filter plate 7 of the present invention are fixedly connected to the bottom of the filter box 1, and the upper ends are movably connected to the top of the filter box 1. The filter box 1 is correspondingly provided with a mounting groove 18 that cooperates with the first filter plate 6 and the second filter plate 7. The side wall of the mounting groove 18 opposite to the vibration component is provided with an elastic component 17 for elastically abutting the corresponding filter plate side. The elastic component 17 enables the filter plate to reciprocate after being struck by the vibration component. The bottom of the filter plate is fixed, and the upper part is connected to the mounting groove through the elastic component 17.

[0031] The present invention discloses a manufacturing method for the above-mentioned industrial dust removal and filtering structure, wherein a first filter plate and a second filter plate are selected according to the dust particle situation of the dust removal environment, the openings on the plate surfaces of the first filter plate and the second filter plate meet the dust removal needs of the industrial environment, the first filter plate and the second filter plate are installed in the filter box, and the lower ends of the first filter plate and the second filter plate are embedded in the card slots opened in the filter box to keep them relatively fixed with the filter box; the dust collecting pipe is arranged between the first filter plate and the second filter plate, and the elastic component is installed on the side of the first filter plate and the second filter plate facing away from the dust collecting pipe, and the corresponding filter plate is connected to the filter box, and the length of the dust collecting pipe is designed according to the height of the first filter plate and the second filter plate, so that the length of the dust collecting pipe covers the filtration area of ​​the first filter plate and the second filter plate, and the jet of the lifting and lowering docking joint is lifted. The aperture is set according to the external air source pressure and the length of the dust collecting tube, the air flow velocity of the jet gas at the end of the dust collecting tube is maintained, and the lower end of the dust collecting tube is installed in the dust box; when cleaning the filter plate dust, the lifting docking joint is driven by the air distribution pipe set in the filter box to move up and down as a whole to complete the docking with the end of the collection tube; the air distribution pipe is connected to the external air source, and one of the air inlet and outlet ends of the filter box is connected to the fan, and the gas suction force for dust removal is provided by the fan; the gas flow rate at the end of the dust collecting tube is simulated by simulation software, and when the external air source pressure is constant, a tapered diameter section is set in the dust collecting tube to perform secondary acceleration on the jet gas, maintain the air flow velocity at the end of the dust collecting tube, thereby reducing the demand for air source pressure.

[0032] The present invention discloses a dust removal system, which uses the above-mentioned industrial dust removal and filtering structure to perform dust removal operations at industrial sites.

[0033] When the industrial dust removal and filtering structure of the present invention is used in a dust removal system to process dust-laden gas, a corresponding suction structure can be connected to the air inlet end 2 so as to directionally absorb dust at different positions and dust-laden gas at different spatial areas. After the dust-laden gas enters the filter box 1 from the air inlet end 2, it passes through the first filter plate 6 and the second filter plate 7 in sequence. After passing through the first filter area 8, it flows to the buffer groove 10 of the second filter plate 7, and is guided to flow to the second filter area 9 through the buffer groove 10. In this process, some dust particles fall from the buffer groove 10 into the dust box 4 under the action of gravity. At this time, the dust outlet 5 of the dust box 4 is in a closed state, and dust is continuously collected. When the filter plate needs to be cleaned after working for a period of time, the fan 19 at the exhaust end 3 of the filter box 1 is closed, the dust outlet 5 is opened, and the fan 19 is turned off. The external air source connected to the lifting docking joint 13 is activated, and the vibration component is started to knock the filter plate. After the dust falls off the filter plate, it is attracted by the negative pressure of the dust collecting tube 11 and will not float to other areas, but will gather in the dust collecting tube 11. Part of the dust will gradually settle under the action of gravity, and the other part will be attracted into the dust collecting tube 11 and enter the dust box 4 under the drive of the air flow, and then enter the dust collecting bag for collecting dust from the dust outlet 5, completing the cleaning of the dust on the filter plate. At the same time, based on the dust cleaning method of the present invention, a purge pipe can be set in the filter box 1, and gas can be sprayed to blow up the dust in other positions in the box, and then the dust in other positions can be cleaned by the suction of the dust collecting tube 11; through the cleaning method of the present invention, the dust cleaning efficiency can be improved, and the escape of dust to other areas of the filter box 1 can be reduced.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
