Description

Technical Field

[0001] The present invention relates to the field of air filtration and purification, and in particular to a filter barrel type filtration and purification structure and a method of using the same. Background Art

[0002] A pulse dust collector is a device that removes dust attached to the filter medium by blowing compressed air. The existing pulse dust collector adopts chambered offline pulse cleaning technology, which overcomes the shortcomings of back-blowing cleaning and general pulse cleaning. It has strong cleaning ability and high dust removal efficiency. It is widely used in industrial production fields such as calcium carbide furnace dust removal and various electric furnace dust removal in ferroalloy plants, and has a significant purification effect on industrial material feeding and production exhaust.

[0003] The prior art publication number is: CN115301011A discloses a pulse dust removal device, including a pulse valve, a shell, a plurality of segmented filtering mechanisms, a first transmission mechanism and a plurality of second transmission mechanisms; a filter cartridge is provided in the shell, and a plurality of segmented filtering mechanisms are installed on the outside of the filter cartridge; the first transmission mechanism is configured to enable the plurality of segmented filtering mechanisms to move inward to cover the filter cartridge, restricting the high-pressure gas blown in reverse by the pulse valve from being blown out from the unblocked part; the plurality of segmented filtering mechanisms are in contact with each other in the axial direction, and their axial lengths are less than the length of the filter cartridge. A pulse dust removal device of the present invention provides a plurality of segmented filtering mechanisms. Before the pulse valve is started to perform a reverse pulse, the filter cartridge is covered by the first transmission mechanism, and a part of the filter cartridge is cleaned intensively. Then, the plurality of half-rings are separated in sequence through the second transmission mechanism. Segmented cleaning of the filter cartridge is achieved, ensuring a more comprehensive cleaning effect of the filter cartridge.

[0004] However, the existing technology still has certain limitations. The existing pulse dust removal technology mainly uses filter cartridges for filtration. However, when the dust and impurity particles carried in the intake air enter the filter mechanism, they will collide and rub against the filter cartridge, causing increased wear of the filter cartridge on the side facing the air inlet, affecting the life and filtering effect of the filter mechanism; at the same time, the pulse dust removal technology uses compressed air to impact the filter holes of the filter cartridge mechanism from the inside to the outside through the compressed air to achieve a dust removal effect, but this dust removal technology has limited effect on cleaning dust particles attached to the outside, and is also prone to generating oily dust in industrial production involving petroleum and chemical production. It is easy to adhere to the filter holes and is difficult to clean, which can easily lead to dust accumulation and clogging of the filter mechanism, affecting the filtering and purification effect of the air.

[0005] How to invent a filter barrel type filtering and purification structure and its use method to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0012] Preferably, the filter strip is designed to be inclined along the axis of the filter barrel mechanism.

[0014] Preferably, a cavity is provided inside the fixed block, and the internal cavity of the fixed block is filled with oily dust dissolving agents such as petroleum ether, alcohol, acetone, etc. The interior of the fixed block is also provided with a piston push block which is movably sleeved for limiting sealing, and a spring for resetting is provided between the piston push block and the interior of the fixed block, and the surface of the fixed block is provided with multiple groups of liquid outlet holes which are connected to the interior of the fixed block.

[0019] A method for using a filter barrel type filtering and purification structure comprises the following steps:

At the same time, during the rotation of the filter barrel mechanism, the magnetic block is driven to move the push rod, which can drive the vibration shaft to periodically impact and vibrate the filter strip. The generated vibration can reduce the adhesion of dust on the surface of the filter strip, loosen and fall off the dust particles, realize automatic dust removal and auxiliary effect of subsequent pulse valve pulse dust removal, improve the overall filtration and purification efficiency, and improve the environmental friendliness of the device.

[0027] When a lot of dust accumulates on the surface of the filter barrel mechanism and the filter strip, the rotation speed of the filter barrel mechanism slows down, and the magnetic force of the driving magnet can drive the movable push block to move down to push the connecting ring and the filter strip, and the dust accumulated on the surface of the filter strip is scraped off by the fixed block, so that the filter strip can be automatically physically scraped and cleaned when there is a lot of dust, thereby achieving an external physical dust removal effect, making up for the difficulty of pulse dust removal in cleaning the dust particles attached to the outside, and ensuring the filtering and purification effect of the filter barrel mechanism; at the same time, the oily dust attached to the surface of the filter strip continues to accumulate and increase in volume during the cleaning process, pushing the piston push block to make the solvent inside the fixed block spray out through the liquid outlet, thereby achieving the dissolution and cleaning of the oily dust, ensuring the purification and filtering effect of the filter barrel mechanism on the air, and ensuring the environmental protection and efficiency of the filtration.

DETAILED DESCRIPTION

[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] Example

[0045] Reference Figure 1-13 A filter barrel type filtration and purification structure includes a filter cartridge 1, a series vacuum pump group 2 and a pulse valve 3 arranged inside the filter cartridge 1. The bottom of the filter cartridge 1 is provided with an ash hopper 4, the side wall of the filter cartridge 1 is provided with an air inlet 11, and the interior of the filter cartridge 1 is also provided with a partition plate 13, and further includes:

[0046] The filter barrel mechanism 5 is arranged inside the filter cartridge 1 and is used to filter the gas entering through the air inlet 11. When the gas entering through the air inlet 11 is impacted by the wind, the filter strips 51 arranged in an annular shape on the side wall of the filter barrel mechanism 5 and having an inclined design absorb the wind force, so that the filter barrel mechanism 5 rotates evenly to withstand the gas impact.

[0047] The cleaning mechanism 56 is arranged at the bottom of the partition plate 13 and is close to the filter barrel mechanism 5. When the filter barrel mechanism 5 rotates, the driving magnetic block 55 arranged on the outer wall of the filter barrel mechanism 5 drives the push rod 563 arranged on the side of the cleaning mechanism 56 to rotate and reset, so that the reset spring 565 arranged under the cleaning mechanism 56 rises and then resets and falls, colliding with the filter strip 51, driving the filter strip 51 to vibrate periodically, reducing the adhesion between the dust on the surface of the filter strip 51 and the filter strip 51, and causing the dust to fall off.

[0048] Reference Figure 2-9The series vacuum group pump 2 is connected to the inner cavity of the filter cartridge 1, and the bottom of the partition plate 13 is symmetrically connected to the filter barrel mechanism 5 through a bearing, and the top of the filter barrel mechanism 5 extends to the top of the partition plate 13, and the outer wall of the filter barrel mechanism 5 is evenly limited along the annular sleeve with multiple groups of filter strips 51, and a spring for resetting is provided between the bottom of the filter strips 51 and the filter barrel mechanism 5, and the outer wall of the filter barrel mechanism 5 is fixedly installed with multiple groups of fixing blocks 52 in the gap between the filter strips 51, and a connecting ring 53 is fixedly installed on the top of the filter strips 51. The connecting ring 53 connects each group of filter strips 51 and the connecting ring 53 into a whole group, and the outer wall of the filter barrel mechanism 5 is fixedly installed with multiple groups of driving magnetic blocks 55 evenly distributed in an annular shape along the outer wall of the filter barrel mechanism 5, and the bottom of the partition plate 13 is fixedly installed with multiple groups of driving magnetic blocks 55 that are opposite to the driving magnetic blocks 55 The cleaning mechanism 56 should be distributed and close to the filter barrel mechanism 5, and the internal limit sealing movably sleeve of the cleaning mechanism 56 is equipped with a group of movable push blocks 561 with a T-shaped design. A groove matching the driving magnetic block 55 is provided on the side of the movable push block 561 close to the driving magnetic block 55. The movable push block 561 is rotatably connected to a group of reset shafts 562 through bearings, and a torsion spring for resetting is provided between the reset shaft 562 and the inside of the movable push block 561. The reset shaft 562 extends to the outer wall of the groove part of the movable push block 561 and is fixedly installed with a push rod 563. The bottom limit movably sleeve of the movable push block 561 is equipped with a vibration shaft 564. A reset spring 565 is connected between the vibration shaft 564 and the inside of the movable push block 561. A connecting rope is provided between the top of the vibration shaft 564 and the side wall of the reset shaft 562.

[0049] It should be noted that the inlet of the air inlet 11 can also be connected to the handheld vacuum cleaner head for suction through a hose, so as to adsorb and filter the dust and pollution in the environment; at the same time, the series vacuum group pump 2 adopts a two-stage series vacuum group pump. Driven by the motor, the two-stage vacuum pump runs at high speed to generate high vacuum negative pressure. Through the two-stage series connection, the front-stage pump and the rear-stage pump can work together to achieve a higher vacuum degree. The front-stage pump can provide a higher suction speed to extract most of the gas, while the rear-stage pump can provide higher suction efficiency to further reduce the gas pressure; in actual use, it can provide higher negative pressure and suction, making cleaning and dust removal more thorough, and can be used for dust removal in construction areas such as electrolytic aluminum trenches, overhead cranes and sintering. The strong negative pressure can not only absorb impurities with lower density such as dust, but also efficiently absorb metal debris with higher density in the processing area, effectively improving the cleaning and purification effect, and having stronger applicability.

[0050] Furthermore, the filter strip 51 is designed to be inclined along the axis of the filter barrel mechanism 5;

[0051] It should be noted that, due to the inclined design of the filter strip 51, when the airflow entering the filter cartridge 1 through the air inlet 11 hits the surface of the filter strip 51, Figure 12 The inclined filter strips 51 can form a larger blocking area for the airflow and increase the airflow resistance, so that the incoming airflow drives the filter strips 51 to further drive the filter barrel mechanism 5 to rotate as a whole, so that the filter barrel mechanism 5 can maintain a rotating state when it is impacted by the gas, so that the surface of the filter barrel mechanism 5 can evenly bear and share the impact of the gas, and avoid the filter barrel mechanism 5 on the side of the air inlet 11 being subjected to a long-term continuous impact of gas and dust, resulting in a large degree of local wear, thereby reducing the service life and increasing the replacement frequency. The improved device drives the filter barrel mechanism 5 to rotate during operation through the kinetic energy generated by the air flow entering the filter barrel 1, so that the filter barrel mechanism 5 as a whole can evenly bear the impact and friction of the powder, which not only avoids excessive local wear, but also makes the gas flow into the filter barrel mechanism 5 evenly from all parts of the filter barrel mechanism 5 through the rotation of the filter barrel mechanism 5, so that each surface of the filter barrel mechanism 5 can purify and filter the airflow at the same time, further improving the overall filtering and purification efficiency of the filter barrel mechanism 5 on the airflow.

[0052] Furthermore, a set of limiting rings 54 for limiting the connection ring 53 are fixedly installed on the outer side wall of the filter barrel mechanism 5 above the connection ring 53.

[0053] Reference Figure 7-8 A cavity is provided inside the fixed block 52, and the internal cavity of the fixed block 52 is filled with oily dust dissolving agents such as petroleum ether, alcohol, and acetone. The interior of the fixed block 52 is also provided with a piston push block 521 which is movably connected to the fixed block 52 in a limited sealing manner. A spring for resetting is also provided between the piston push block 521 and the interior of the fixed block 52. The surface of the fixed block 52 is provided with multiple groups of liquid outlet holes 522 which are connected to the interior of the fixed block 52.

[0054] Furthermore, the cavity inside the fixing block 52 is L-shaped, the surface of the fixing block 52 is inclined, and the fixing block 52 fits the side wall of the filter strip 51;

[0055] It should be noted that when the filter strip 51 and the fixed block 52 move relative to each other, the inclined design of the fixed block 52 can facilitate the removal of dust and powder scraped off the surface of the filter strip 51 along the inclined surface, thereby avoiding the accumulation of dust and powder on the surface of the fixed block 52.

[0056] Furthermore, a one-way valve for allowing fluid to flow from the inside of the fixed block 52 toward the outside of the fixed block 52 is provided inside the liquid outlet 522, and a one-way valve for allowing fluid to flow from the outside of the fixed block 52 toward the inside of the fixed block 52 is provided inside the piston push block 521.

[0057] It should be noted that the one-way valve arranged inside the liquid outlet 522 can allow the cleaning solvent to flow out in one direction to prevent the solvent from flowing back. The one-way valve inside the piston push block 521 can prevent the solvent from flowing out through the piston push block 521 and at the same time, when the piston push block 521 is reset, suck external air into the fixed block 52 to keep the interior of the fixed block 52 in a saturated state. When the piston push block 521 is compressed again, since the internal cavity of the fixed block 52 is L-shaped, air is deposited above the cavity. When the piston push block 521 moves downward, the bottom solvent can be pressed out through the liquid outlet 522, thereby realizing full utilization of the solvent.

[0058] Reference Figure 9 The top horizontal block of the movable push block 561 is designed as a group of magnetic blocks, and the magnetic poles of the movable push block 561 close to the embedded magnetic block 568 and the driving magnetic block 55 are all designed to be opposite. The magnetic force of the driving magnetic block 55 is greater than that of the embedded magnetic block 568.

[0059] It should be noted that when it is not close to the driving magnet 55, the embedded magnet 568 can drive the movable push block 561 to always be above the inner side of the cleaning mechanism 56 and fit into the inner side of the cleaning mechanism 56. When the driving magnet 55 rotates to be close to the cleaning mechanism 56, since the magnetism of the driving magnet 55 is greater than the magnetism of the embedded magnet 568, the driving magnet 55 can attract the movable push block 561 toward the driving magnet 55, causing the movable push block 561 to move downward until the driving magnet 55 rotates to move away from the cleaning mechanism 56. At this time, the movable push block 561, which has lost the magnetic attraction of the driving magnet 55, is reset under the magnetic attraction of the embedded magnet 568.

[0060] Furthermore, a group of first communicating holes 566 communicating with the top of the inner cavity of the cleaning mechanism 56 are formed on the side wall of the cleaning mechanism 56, and two groups of second communicating holes 567 communicating with the inner cavity of the cleaning mechanism 56 are formed on the bottom of the cleaning mechanism 56, and a one-way valve is provided inside one group of the second communicating holes 567 so that the flow direction is from the outside of the cleaning mechanism 56 to the inside of the cleaning mechanism 56; the movable push block 561 maintains a sealed sliding connection with the inner side wall of the cleaning mechanism 56, and the T-shaped design of the movable push block 561 divides the interior of the cleaning mechanism 56 into three groups of air chambers, namely one group at the top and two groups at the bottom, and a connecting groove is provided inside the movable push block 561 so that the two groups of air chambers at the bottom are connected;

[0061] It should be noted that, when the filter barrel mechanism 5 rotates normally, when the cleaning mechanism 56 is close to the driving magnetic block 55, the driving magnetic block 55 can attract the movable push block 561 toward the driving magnetic block 55, so that the movable push block 561 moves downward. During the downward movement of the movable push block 561, since there is air in the air chamber below the movable push block 561, the movable push block 561 needs to discharge the air inside the lower air chamber through one of the sets of second connecting holes 567 when moving downward, resulting in a slower downward movement of the movable push block 561. As the filter barrel mechanism 5 continues to rotate, the driving magnetic block 55 and the cleaning mechanism 56 are separated from the close state, and the movable push block 561, which has lost the magnetic force of the driving magnetic block 55, rises and resets under the action of the magnetic force of the embedded magnetic block 568. It should be noted that It is obvious that during the ascending process of the movable push block 561, negative pressure is formed in the air chamber below the movable push block 561, and air needs to be sucked in through the second communicating holes 567. Since a one-way valve is provided inside one group of the second communicating holes 567, during the resetting process, air can be replenished to the internal cavity of the cleaning mechanism 56 through the two groups of second communicating holes 567 at the same time, so that when the movable push block 561 descends, air can only be exhausted through one group of the second communicating holes 567 to eliminate air resistance, while when the movable push block 561 ascends and resets, air can be sucked in through the two groups of the second communicating holes 567 to eliminate negative pressure, thereby increasing the time required for the movable push block 561 to move downward, and avoiding frequent downward movement of the movable push block 561 when the filter barrel mechanism 5 rotates normally, which affects the normal filtering work of the filter strip 51.

[0062] When more dust accumulates on the surface of the filter barrel mechanism 5 and the filter strip 51, refer to Figure 13 When the filter strip 51 is full of dust, the filter strip 51 blocks the airflow, and the filter strip 51 has a smaller blocking area, which causes the filter barrel mechanism 5 to rotate slower. Furthermore, when the driving magnetic block 55 rotates to be close to the cleaning mechanism 56, the magnetic force of the driving magnetic block 55 can attract the movable pushing block 561 toward the driving magnetic block 55, so that the movable pushing block 561 moves downward slowly, and the movable pushing block 561 pushes the connecting ring 53, further driving the entire filter strip 51 to move downward, and the fixed block 52 can scrape off the dust accumulated on the surface of the filter strip 51, and fall down through the inclined surface of the fixed block 52, so as to achieve physical scraping and cleaning of the filter strip 51 when there is a lot of dust. The accumulated dust particles are separated from the contact with the filter strip 51 by physical scraping, thereby achieving the external physical dust removal effect, thereby making up for the difficulty of pulse dust removal in cleaning the dust particles attached to the outside, and ensuring the filtering and purification effect of the filter barrel mechanism 5.

[0063] Furthermore, when the filter strip 51 is driven to move for dust removal, when the surface of the filter strip 51 is scraped by the fixed block 52, the oily dust accumulated on the surface of the filter strip 51 will continue to accumulate into clumps and adhere together under the movement of the filter strip 51, and it is difficult to fall off on its own. At this time, as the filter strip 51 continues to move downward, the volume of the oily dust clumps accumulated on the surface of the filter strip 51 continues to increase. At this time, the resistance encountered by the piston push block 521 continues to increase, and the oily dust clumps push the piston push block 521 during the continuous descent of the filter strip 51. The dissolving agent inside the fixed block 52 can be sprayed out through the liquid outlet 522 by the piston push block 521 to dissolve the oily dust and make it fall along the inclined surface of the liquid outlet 522. Combined with the pulse cleaning of the pulse valve 3, the residual oily dust after dissolution can be further deeply cleaned.

[0064] A method for using a filter barrel type filtering and purification structure comprises the following steps:

[0065] S1: Start the series vacuum pump 2 and introduce the gas to be filtered through the air inlet 11;

[0066] S2: The gas enters and drives the filter barrel mechanism 5 to rotate, and the gas is filtered by the filter barrel mechanism 5;

[0067] S3: The vibration shaft 564 periodically impacts and vibrates the filter strip 51 to remove dust;

[0068] S4: The movable push block 561 pushes the filter strip 51 to move and mechanically remove dust and oily dust from the surface of the filter strip 51;

[0069] S5: Exhaust the filtered gas.

[0070] The working principle of the filter barrel type filtration purification structure and its use method:

[0071] During operation, the gas to be filtered enters through the air inlet 11 and is filtered through the filter barrel mechanism 5 under the suction of the series vacuum pump 2. During this process, when the airflow enters the filter barrel 1 and impacts the surface of the filter strip 51, Figure 12The filter strips 51 are tilted to form a larger blocking area for the airflow, thereby improving the airflow resistance and utilization rate, driving the filter barrel mechanism 5 to rotate as a whole, so that the filter barrel mechanism 5 can keep rotating when it is impacted by the gas, and the surface of the filter barrel mechanism 5 can evenly bear and share the impact of the gas, thereby avoiding the filter barrel mechanism 5 on the side of the air inlet 11 being subjected to a long-term continuous impact of gas and dust, thereby reducing the service life and increasing the replacement frequency. The improved device drives the filter barrel mechanism 5 to rotate during operation through the kinetic energy generated by the air flow entering the filter barrel 1, so that the filter barrel mechanism 5 as a whole can evenly bear the impact and friction of the powder, which not only avoids excessive local wear, but also allows the gas to flow in evenly from all parts of the filter barrel mechanism 5 through the rotation of the filter barrel mechanism 5, so that all surfaces of the filter barrel mechanism 5 can purify and filter the airflow at the same time, further improving the overall filtering and purification efficiency of the filter barrel mechanism 5 on the airflow;

[0072] During the rotation of the filter barrel mechanism 5, refer to Figure 11 When the driving magnetic block 55 comes into contact with the push rod 563, it can drive the push rod 563 and the reset shaft 562 to rotate, and drive the vibration shaft 564 to rise through the connecting rope. At this time, the reset spring 565 is stretched, and when the driving magnetic block 55 passes through the push rod 563 and is disengaged from the push rod 563, the reset shaft 562 is reset under the action of the torsion spring, and the reset spring 565 is reset, driving the vibration shaft 564 to reset and fall, hitting the connecting ring 53, and at the same time transmitting the vibration force of the impact to the filter strip 51, realizing periodic vibration of the filter strip 51, reducing the adhesion between the dust on the surface of the filter strip 51 and the filter strip 51, causing the dust to loosen and fall off, realizing automatic dust removal and auxiliary effect of pulse dust removal of the subsequent pulse valve 3, and the removed dust and large particles of impurities fall to the ash hopper 4 under the action of gravity to be collected and cleaned;

[0073] When more dust accumulates on the surface of the filter barrel mechanism 5 and the filter strip 51, refer to Figure 13 When the filter strip 51 is full of dust, the filter strip 51 blocks the airflow, and the filter strip 51 has a smaller blocking area, which causes the filter barrel mechanism 5 to rotate slower. Furthermore, when the driving magnetic block 55 rotates to be close to the cleaning mechanism 56, the magnetic force of the driving magnetic block 55 can attract the movable pushing block 561 toward the driving magnetic block 55, so that the movable pushing block 561 moves downward slowly, and the movable pushing block 561 pushes the connecting ring 53, further driving the entire filter strip 51 to move downward, and the fixed block 52 can scrape off the dust accumulated on the surface of the filter strip 51, and fall down through the inclined surface of the fixed block 52, so as to achieve physical scraping and cleaning of the filter strip 51 when there is a lot of dust. The accumulated dust particles are separated from the contact with the filter strip 51 by physical scraping, thereby achieving the external physical dust removal effect, thereby making up for the difficulty of pulse dust removal in cleaning the dust particles attached to the outside, and ensuring the filtering and purification effect of the filter barrel mechanism 5.

[0074] Furthermore, when the filter strip 51 is driven to move for dust removal, when the surface of the filter strip 51 is scraped by the fixed block 52, the oily dust accumulated on the surface of the filter strip 51 will continue to accumulate into clumps and adhere together under the movement of the filter strip 51, and it is difficult to fall off on its own. At this time, as the filter strip 51 continues to move downward, the volume of the oily dust clumps accumulated on the surface of the filter strip 51 continues to increase. At this time, the resistance encountered by the piston push block 521 continues to increase, and the oily dust clumps push the piston push block 521 during the continuous descent of the filter strip 51. The dissolving agent inside the fixed block 52 can be sprayed out through the liquid outlet 522 by the piston push block 521 to dissolve the oily dust and make it fall along the inclined surface of the liquid outlet 522. Combined with the pulse cleaning of the pulse valve 3, the residual oily dust after dissolution can be further deeply cleaned.

[0075] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
