Description

Technical Field

[0001] The invention relates to the technical field of smoke dust filtering, and in particular to a filtering treatment device and a treatment method for smoke dust treatment. Background Art

[0002] In the process of industrial production, especially in metal cutting, welding, grinding and other operations, a large amount of smoke and dust will be generated. These smoke and dust contain a large number of metal particles, oxides and other harmful substances, which pose a serious threat to the respiratory system, eyes and skin of operators. At the same time, smoke and dust emissions will also pollute the external environment and affect the air quality;

[0003] In order to protect the health of workers, improve the working environment and promote green production, smoke dust needs to be filtered before discharge.

[0004] A negative pressure low-pressure pulse bag dust removal device for treating boiler smoke is disclosed in the patent application with reference publication number CN204799019U. A guide plate is added above the air inlet duct to guide the dust-containing gas to flow downward and then turn upward, so that the dust-containing gas can fully contact the filter bag under the action of negative pressure to achieve an ideal filtering effect; the dust in the filter bag can be easily removed by a pulse jet cleaning system.

[0005] When the existing bag-type smoke filter treatment device filters the smoke, the dust in the smoke will continue to adhere to the surface of the filter bag, so most of them use pulsed high-pressure gas to purge the filter bag to ensure the normal circulation of air inside and outside the filter bag; and when the high-pressure air is blown downward from the bag opening of the filter bag, it will hinder the discharge of the smoke, resulting in the interruption of the dust filtration process, and the smoke cannot be filtered continuously. Moreover, the filter bag is subjected to the impact of pulsed high-pressure gas for a long time, which is easy to damage the filter bag structure itself and shorten the service life of the filter bag. In addition, the filter bag device can only filter the smoke once, and it is difficult to fully filter the dust in the smoke. Partial filtration, for example, the negative pressure low-pressure pulse bag dust removal device for treating boiler smoke with the reference publication number CN204799019U, this patent uses a pulse jet cleaning system to spray high-pressure gas to remove dust on the surface of the filter bag, and the sprayed high-pressure gas will hinder the smoke from passing through the filter bag, making it impossible for the smoke to continue to pass through the filter bag, thereby affecting the filtering effect of the smoke, and it is difficult to fully filter the dust in the smoke with only a single-layer filter bag, and the filter bag will be subjected to the impact of pulse gas for a long time, which will accelerate its own aging speed and increase the replacement frequency of the filter bag, thereby increasing the cost of using the filter bag.

[0006] Therefore, the present invention proposes a filtering treatment device and a treatment method for smoke treatment to solve the above problems. Summary of the invention

In addition, the filter bag is subjected to the impact of pulsed high-pressure gas for a long time, which easily damages the structure of the filter bag itself and accelerates its aging speed, thereby increasing the replacement frequency of the filter bag and increasing the cost of use; and the traditional filter bag can only filter the smoke once, and it is difficult to fully filter the dust in the smoke.

[0036] The present invention provides a filtering treatment device and treatment method for smoke dust treatment. Compared with the prior art, it has the following beneficial effects:

[0037] 1. A filtering treatment device and treatment method for smoke dust treatment, which is provided with a smoke dust filtering mechanism, wherein a first, a second and a third smoke dust filtering chamber are provided inside the mechanism, and the interiors of the three filtering chambers jointly form a fixed flow path for the smoke dust, so that the smoke dust can flow along a preset path, providing conditions for subsequent filtration of dust of various particle sizes in the smoke dust;

[0038] Secondly, when the smoke flows along a preset path, it can pass through the primary, secondary and tertiary filter components in sequence, so that the dust of different particle sizes in the smoke can be filtered step by step from large particle size to small particle size, thereby achieving the effect of multi-stage filtration of the smoke.

[0040] Secondly, the transmission component can synchronously transmit power to the cleaning component, driving the cleaning component to rotate rapidly, so that the primary, secondary and tertiary filter components can rotate while continuously cleaning the surface of the filter bags passing through the cleaning component, thereby achieving the effect of self-cleaning by utilizing the power of smoke and dust.

[0042] Secondly, compared with the traditional pulse air blowing method of cleaning filter bags, the mechanical cleaning method used in the present invention can achieve the cleaning effect while also providing maximum protection for the filter bags, avoiding damage to the filter bag structure, thereby extending the service life of the filter bags, reducing the replacement frequency of the filter bags, and achieving the purpose of saving the cost of using the filter bags.

[0043] 4. A filtering treatment device and treatment method for smoke dust treatment, which uses the principle of a Venturi tube by setting a dust exhaust component, and uses the power of the dust cleaning component to intermittently push the piston to move, so that the air inside the tube body composed of an inlet section, a throat pipe and a diffusion section can flow quickly in a short time, so that an air pressure lower than the external pressure can be generated at the throat position. Under the action of the internal and external pressure difference, the dust swept by the dust cleaning component can be sucked into the throat position by the suction pipe, and when the piston pushes the air to flow again, this part of the dust can be discharged from the diffusion section, thereby achieving the effect of automatically discharging the dust filtered in the smoke dust filtering mechanism;

The multi-stage filtering assembly has the ability to filter dust of different particle sizes in the smoke, and the top and bottom of the shell assembly are respectively provided with a power conversion assembly 712 and a transmission assembly. The power conversion assembly 712 is used to convert the smoke airflow power into axial rotational force, and the axial rotational force is transmitted to the multi-stage filtering assembly through the transmission assembly to drive the multi-stage filtering assembly to complete the smoke filtering and self-cleaning process, and at the same time provide power for the dust discharge process under filtration.

[0094] like Fig.23 The second embodiment is shown, which is mainly different from the first embodiment in that: a filtering and processing device for smoke and dust treatment, the dust exhaust component 721 includes a venturi tube fixedly arranged inside the chip exhaust channel, the venturi tube includes an inlet section c1, a throat c2, and a diffusion section c3 which are fixedly connected in sequence, one end of the inlet section c1 is fixedly arranged with a support plate c4, a piston rod c5 is rotated through the inside of the support plate c4, one end of the piston rod c5 and a piston c6 is fixedly arranged inside the inlet section c1, the other end of the piston rod c5 is fixedly arranged with a hemispherical body c7, a spring c8 is slidably sleeved on the outer wall of the piston rod c5 and between the hemispherical body c7 and the support plate c4 to push the piston c6 to return, and both sides of the outer wall of the throat c2 are fixedly arranged with a suction pipe c9 connected to the inside thereof. One end of the suction pipe c9 passes through the bearing cylinder 71 and extends to the inside of the ash cleaning chamber 742, and its end is trumpet-shaped for sucking the scraped smoke and dust.

[0095] The present invention also discloses a treatment method of a filtering device for smoke treatment, using the filtering device for smoke treatment, the method comprising the following steps:

[0096] Step 1: The smoke containing dust particles enters the cavity of the smoke treatment box 2 through the smoke inlet 3, and the larger dust particles fall into the ash hopper 5 under the action of their own gravity; the bottom of the ash hopper 5 is equipped with an ash discharge device, which is a known technology and will not be described here;

[0097] Step 2, the smoke enters the interior of the smoke filter mechanism 7, and after multiple filtrations by the multi-stage filter assembly, the clean gas is discharged through the top of the smoke filter mechanism 7, and then discharged into the atmosphere through the exhaust port 4; the specific process is: since the long air inlet 72 is the only smoke inlet on the carrier tube 71, the smoke enters the chamber of the smoke treatment box 2 located below the partition 6, and enters the space located in the No. 1 smoke filter chamber 73 through the long air inlet 72, and the smoke passes through the filter bag 783 in the first-level smoke filter assembly 78 and then enters the No. 2 smoke filter chamber 74 through the through groove 1 76. In this process, larger particles of dust are filtered by the filter bag 783 in the No. 1 smoke filter chamber 73;

[0098] The smoke entering the second smoke filter chamber 74 passes through the filter bag 783 in the secondary smoke filter assembly 79 and then enters the third smoke filter chamber 75 through the second through slot 77. In this process, small particles of dust are filtered by the filter bag 783 in the second smoke filter chamber 74.

[0099] A small amount of fine dust particles are mixed in the smoke after two filtrations. The smoke passes through the outer wall of the filter bag 783 in the third-stage smoke filter assembly 710 in the third smoke filter chamber 75 and is input into the power conversion assembly 712 through the top of the third smoke filter chamber 75. It should be noted that the dust particles that can be filtered by the filter bag 783 in the first-stage smoke filter assembly 78, the second-stage smoke filter assembly 79, and the third-stage smoke filter assembly 710 in the first smoke filter chamber 73, the second smoke filter chamber 74, and the third smoke filter chamber 75 decrease in size, that is, the filtering accuracy increases in sequence.

[0100] When the smoke that has been filtered three times passes through the cylinder a1, the airflow pushes the fan blade a3 to rotate. Since the fan blade a3 is connected to the transmission shaft 713, the transmission shaft 713 synchronously drives the ring gear 1 714 and the ring gear 2 715 to rotate at a low speed. Since multiple gears 1 716 are meshed and connected with the ring gear 1 714, the assembly cylinder 2 717 at multiple positions can drive the primary smoke filter assembly 78 or the secondary smoke filter assembly 79 or the tertiary smoke filter assembly 710 at the corresponding position to rotate while the gear 1 716 at the corresponding position rotates, so that the filter bag 783 in the primary smoke filter assembly 78 is opposite to the long air inlet 72 at different positions, and the filter bags 783 in the secondary smoke filter assembly 79 and the tertiary smoke filter assembly 710 are opposite to the through groove 1 76 and the through groove 2 77 at different positions respectively; during the rotation of the primary smoke filter assembly 78, the secondary smoke filter assembly 79 and the tertiary smoke filter assembly 710, the filtering surfaces at different positions of the three are used to participate in the work of filtering smoke;

[0101] At the same time, the second gear ring 715 rotates while synchronously driving the second gears 718 at multiple positions to rotate, and the power is transmitted to the dust cleaning components 711 at the corresponding positions through the assembly shaft 719. When the dust cleaning components 711 rotate synchronously with the assembly shaft 719, the bristles on the outer wall of the long strip brush b3 clean the outer wall of the first-stage smoke filter component 78, the second-stage smoke filter component 79, or the third-stage smoke filter component 710 at the corresponding position, and the swept dust falls on the bottom of the No. 1 smoke filter chamber 73, the No. 2 smoke filter chamber 74, or the No. 3 smoke filter chamber 75;

[0102] While the assembly shaft 719 rotates, the cam 720 intermittently pushes the hemispherical body c7, and the piston rod c5 pushes the piston c6 to move toward the inside of the inlet section c1. The gas inside the inlet section c1 is quickly pushed out through the diffusion section c3. According to the Venturi tube principle, in the process of the airflow flowing through the throat c2, a negative pressure is generated at the throat c2 position, so that the dust deposited at the bottom of the No. 1 smoke filter chamber 73 or the No. 2 smoke filter chamber 74 or the No. 3 smoke filter chamber 75 is sucked into the inlet section c1 through the suction pipe c9. As the piston c6 is pushed again, the dust sucked into the inlet section c1 is pushed out of the diffusion section c3 along with the flowing airflow, and this part of the dust falls into the ash hopper 5 under the action of its own gravity.

[0103] Step 3: When the clean gas is discharged from the smoke filter mechanism 7, it simultaneously drives the power conversion component 712 to operate. The power conversion component 712 transmits power to the multi-stage filter component through the transmission component. The multi-stage filter component performs self-cleaning while filtering the smoke.

[0104] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0105] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
