Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust removal and filtration, in particular to a dust removal device for a slagging machine and a dust removal method. BACKGROUND

[0002] In the process of steel smelting, the slagging machine is a key equipment used for removing the molten slag in the furnace mouth area in the later stage of converter or electric furnace smelting. With the advancement of molten steel smelting, complex molten slag is continuously produced in the furnace. If it is not removed in time, it will not only affect the purity of the molten steel, but also may block the tapping hole, and even cause production safety accidents. Therefore, the slagging operation is an important link to ensure the quality of molten steel and the smoothness of the smelting process.

[0003] However, in the process of slagging operation, the contact and extrusion of high-temperature molten slag with mechanical devices, as well as the crushing and transportation of slag blocks, can easily lead to the generation of a large amount of smoke and fine particles. These dusts mainly come from the physical crushing of molten slag and the volatilization of volatile substances at high temperatures, and often contain metal oxides, silicates and other harmful substances, with fine particle size and strong fluidity, which can rapidly spread in the workshop and form visible smoke pollution. Such dust not only seriously affects the visual environment in the workshop, but also threatens the health of the operators. Long-term inhalation of such high-temperature smoke may cause respiratory diseases, and the deposition of dust in the workshop may also accelerate equipment wear and affect the stability of the electrical system.

[0004] At present, the dust removal device matched with the slagging machine in the industry generally uses a rigid filter plate with excellent high-temperature resistance as the core filter unit. This is mainly because the flexible filter cloth is easily ablated and damaged by flying metal sparks in a high-temperature environment, affecting the service life and filtering stability. With the continuous dust removal operation, dust accumulates on the surface of the filter plate. When the adhesion reaches a certain degree, the system will trigger the dust cleaning mechanism through manual judgment or automatic detection by a pressure difference sensor, and some equipment also uses a timing control mode to start the cleaning process to maintain the continuous filtering performance of the filter plate. In the dust cleaning process, the existing device mostly uses a mechanical cleaning method, and the common practice is to use an automatic steel brush or scraper structure to tightly adhere to the surface of the filter plate for reciprocating motion. In this process, a high-frequency micro-vibration device is usually used to apply slight vibration to the filter plate to enhance the peeling effect of the dust and the surface of the filter plate. This combined dust cleaning method can effectively remove most of the dust and ensure that the filter plate restores good air permeability and filtering efficiency after cleaning.

[0005] However, the current dust removal mechanism based on manual intervention or pressure difference sensor triggering has certain limitations. On the one hand, manual judgment has a response lag problem, and although the pressure difference sensor system can achieve automatic control, the equipment cost is high, and there is still a risk of misjudgment in the judgment of dust removal time. On the other hand, more importantly, the existing dust removal method has limited effect on dust removal for dust embedded in the deep filter hole. When the steel brush or scraper mechanism moves on the surface of the filter plate, it is difficult to effectively touch and remove the particles stuck in the internal filter hole. At the same time, in order to avoid damaging the rigid filter plate structure, a micro-amplitude high-frequency vibration device is used, which has a small amplitude and limited energy, and it is difficult to effectively strip the dust that is firmly attached or embedded deep. This incomplete dust removal problem easily leads to local blockage of the filter plate, affecting the overall filtration efficiency. In addition, the existing dust removal device mechanical dust removal system has a complex structure, and the manufacturing and maintenance cost is also relatively high, which limits its wide application to some extent.

[0006] In view of the above problems, it is urgent to make innovative design on the basis of the existing dust removal device and dust removal method of the slag scraper. SUMMARY

[0059] A dust removal method for a muck loader, comprising the following steps:

[0060] S. When a large amount of dust clogs the surface of the elastic filter plate and the No. 3 vertical groove, the gas has difficulty passing through the elastic filter plate. Under the continuous operation of the vacuum fan, the air pressure between the elastic filter plate and the sealing plate decreases, and the sealing plate is passively sucked to the vicinity of the elastic filter plate.

[0061] S1-1, The displacement trigger lever of the sealing plate rotates and forces the No. 1 connecting column to move vertically downward. When the No. 1 connecting column starts to move downward, it quickly pulls the lifting cover away from the cylindrical protrusion. This causes the horizontal plate to fall rapidly one step ahead of the lifting cover under the rebound pull of the No. 3 spring. The elastic filter plate quickly rebounds and recovers. The vibration and impact force of the elastic filter plate when it rebounds forcefully pushes the dust attached to its surface and the dust blocked in the No. 3 longitudinal groove away from the elastic filter plate. The lifting cover then falls down to the diagonal below the cylindrical protrusion and moves again to the position directly below the cylindrical protrusion due to the influence of the guide groove.

[0062] S1-2. After the dust clogging the elastic filter plate is ejected, the gas re-enters the processing box from the air inlet hood. The air pressure between the elastic filter plate and the sealing plate rises. Under the rebound pull of the second spring, the sealing plate resets. The sealing plate triggers the lever to rotate in the opposite direction again. The first connecting column moves up quickly. The lifting hood lifts the cylindrical protrusion and moves up quickly at the same time, squeezing the elastic filter plate and forcing it to bend, waiting for the next release.

[0063] S2, in step S, the dust falling into the channel shell when the elastic filter plate is ejected, due to a small part of the wind power generated by the dust suction fan is transmitted to the dust collection box by the suction pipe, so the dust collection box and the channel shell are always in a state of micro low pressure, the dust falling into the channel shell is not easy to rise again, but is sucked into the dust collection box, and under the blocking and guidance of the dust baffle, the dust is concentrated in the inside of the lower end of the dust collection box, and the filtered gas is discharged from the exhaust cylinder after being combined with the filtered gas in the treatment box.

[0064] Compared with the prior art, the beneficial effects of the present application are:

[0065] 1, the present application does not need to rely on additional power equipment, only by the change of air pressure between the elastic filter plate and the sealing plate to judge the clogging condition of the elastic filter plate, compared with artificial judgment and instrument detection, its precision is better, the dust removal reaction is better, and the manufacturing and using cost is lower. At the same time, when the elastic filter plate is seriously clogged, the displacement of the sealing plate triggers the auxiliary component, so that the elastic filter plate rebounds suddenly, on the one hand, the dust attached to the surface of the elastic filter plate is pushed away by the elastic force of the elastic filter plate, on the other hand, the dust stuck in the three vertical grooves on the surface of the elastic filter plate is "pushed out" by the diameter change of the three vertical grooves and the inertia lag of the dust, so that the dust which is firmly attached or embedded deep is effectively stripped, realizing high efficiency of dust removal operation.

DETAILED DESCRIPTION

[0084] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0085] Please refer to Figures 1 to 17 The present application provides a technical solution: a dust removal device and method for a slagging machine, comprising a slagging equipment 1 and a processing box 2 fixed at one end of the slagging equipment 1, further comprising:

[0086] The elastic filter plate 7 is arranged inside the processing box 2 to remove dust by rapid rebound deformation, the dustproof cover 8 is fixedly arranged in the processing box 2, the auxiliary assembly is arranged in the processing box 2 and the dustproof cover 8 to control the adaptive bending and rebound of the elastic filter plate 7, and the dust collecting assembly is arranged below the processing box 2;

[0087] In specific implementation, the material of the elastic filter plate 7 includes but is not limited to high-performance nickel-based superalloy and special austenitic stainless steel. The selected material needs to have high-temperature resistance and good creep resistance. The specific material can be selected according to the requirement, and the present application does not make too much elaboration here. In addition, the dustproof cover 8 needs to cover some important parts in the auxiliary assembly in the safety area to prevent dust from entering the dustproof cover 8 in large quantities and causing serious interference to the movement of the auxiliary assembly.

[0088] The auxiliary assembly includes the sealing plate 22 movably arranged in the processing box 2 through a sliding rail, the horizontal plate 9 movably arranged in the dustproof cover 8, the push rod 12 symmetrically arranged on the inner wall of the processing box 2, the long plate 18 fixedly arranged on the top end of the inner wall of the dustproof cover 8, and the lifting cover 17 movably arranged in the dustproof cover 8.

[0089] The dust collecting assembly includes the channel shell 6 fixedly arranged at one end of the bottom of the processing box 2 and the dust collecting box 5 fixedly arranged at the other end of the bottom of the processing box 2.

[0090] One side of the processing box 2 is fixedly connected with the air inlet cover 3;

[0091] The top end of the processing box 2 is fixedly connected with the exhaust cylinder 4, and the dust suction fan is arranged in the exhaust cylinder 4.

[0092] The air inlet cover 3 and the sealing plate 22 are separated by the elastic filter plate 7.

[0093] The exhaust cylinder 4 is located between the elastic filter plate 7 and the sealing plate 22.

[0094] In specific implementation, the air inlet cover 3 should be arranged on the upper side of the processing box 2. On the one hand, it can reduce the excessive interference of air flow to the dust falling into the channel shell 6. On the other hand, in order to prevent the dust adhered to the surface of the elastic filter plate 7 from being brought into the dustproof cover 8, the lower end of the elastic filter plate 7 is not provided with the third vertical groove 31. The upper arrangement of the air inlet cover 3 can prevent the dust and air flow from contacting the lower end of the elastic filter plate 7. In addition, as shown in the attached drawings, the air inlet cover 3 is provided with the first vertical groove 30 and the second vertical groove 32. Figure 3As shown, the elastic filter plate 7 is in a bent state, and its lower end is almost blocked by the middle section, and the upward airflow and the gravity of the dust further prevent the lower end of the elastic filter plate 7 from adhering to the dust. In addition, even if the sealing plate 22 is adsorbed to the direction close to the elastic filter plate 7, the sealing plate 22 will not pass the bottom of the exhaust cylinder 4, which will ensure that the airflow is not hindered after passing through the filter hole 32 and is discharged from the exhaust cylinder 4.

[0095] The top end of the elastic filter plate 7 is rotationally connected to the inner wall of the top end of the processing box 2;

[0096] The bottom end of the elastic filter plate 7 is rotationally connected to the top end of the horizontal plate 9;

[0097] The width of the elastic filter plate 7 is consistent with the width of the processing box 2;

[0098] The surface of the elastic filter plate 7 is uniformly provided with a plurality of groups of filter holes 32;

[0099] In specific implementation, the two sides of the elastic filter plate 7 and the inner wall of the processing box 2 are as close as possible without contact, and even if there is a very small gap, the width of the gap cannot be greater than the diameter of the filter hole 32 to prevent dust from passing through the gap. The top end of the elastic filter plate 7 can only rotate and cannot move in other directions. It needs to be emphasized that the initial state of the elastic filter plate 7 needs to be kept in a slightly bent state, as shown in the attached Figure 4 As shown, that is, after the elastic filter plate 7 is restored, it is not completely straightened, but has a certain bending, so that when the elastic filter plate 7 is bent again, the bending direction is uncontrollable, causing the device to fail to filter. In addition, as shown in the attached Figure 5 and the attached Figure 6 As shown, when the elastic filter plate 7 is bent, the left side is in a stretched state, and the right side is in a compressed state, and the hole diameter of the filter hole 32 gradually decreases from the left side to the right side of the elastic filter plate 7. At this time, some small particle dusts, even if their diameters are smaller than the filter hole 32, are also difficult to pass through the filter hole 32, but are stuck in the filter hole 32, further improving the filtering effect. When the elastic filter plate 7 rebounds, the rebound stroke of the left side is slightly greater than that of the right side, which is similar to running, and the starting point is the same, the outer circle stroke is greater than the inner circle stroke, so the rebound speed of the elastic filter plate 7 from right to left gradually slows down, and the elastic filter plate 7 suddenly shifts to the right when rebounding, and the inertia of the dusts stuck in the filter hole 32 lags behind, so that the dusts are abandoned in the original position without passing through the filter hole 32, or even being pushed to the channel shell 6 by the filter hole 32.

[0100] The width of the dustproof cover 8 is consistent with the width of the processing box 2, and the joint is sealed;

[0101] The upper end of one side of the dustproof cover 8 close to the air inlet cover 3 is provided as a smooth inclined surface.

[0102] In practical implementation, the top of the dust cover 8 has a slot for the upper end of the horizontal plate 9 to pass through. The width of the slot must be the same as the width of the horizontal plate 9. When the elastic filter plate 7 is in a bent state, that is, when the horizontal plate 9 is at its top, the device is in the filtering state. At this time, the horizontal plate 9 blocks the slot, the only channel connecting the dust cover 8 to the inside of the treatment box 2, to prevent dust from entering the dust cover 8 in large quantities through the slot. In addition, it should be noted that when the elastic filter plate 7 rebounds, its lower end will pass through the slot and insert into the dust cover 8. Therefore, the width of the slot needs to be determined according to the movement trajectory of the lower end of the elastic filter plate 7 when it rebounds. Simply put, when the elastic filter plate 7 rebounds, the gap between the side of its lower end facing the air inlet hood 3 and the inner wall of the slot should be as small as possible to prevent a large amount of dust from falling into the dust cover 8 through the gap of the slot after the elastic filter plate 7 rebounds.

[0103] The auxiliary components also include a No. 3 spring 24 fixed between the bottom of the horizontal plate 9 and the bottom of the inner wall of the processing box 2, and a No. 2 connecting column 16 fixed at one end of the lifting cover 17;

[0104] A locking groove 13 is provided through the middle of one end of the lever 12, and a connecting post 14 is movably inserted inside the locking groove 13.

[0105] The inner wall of the processing box 2 has a first vertical groove 21, and one end of the first connecting column 14 passes through the anti-jamming groove 13 and is movably inserted into the first vertical groove 21.

[0106] In specific implementation, the No. 1 connecting column 14 can only move back and forth vertically along the interior of the No. 1 longitudinal groove 21. Meanwhile, as shown in the attached... Figure 10 As shown, the part of the first connecting post 14 that slides inside the lever 12 is set as a cylindrical structure that has been polished and lubricated. When the lever 12 rotates, it will force the first connecting post 14 to move. The movement trajectories of the two are in different directions. Therefore, the design of the anti-jamming groove 13 can prevent the two from interfering with each other. While the first connecting post 14 slides inside the anti-jamming groove 13, the two also have a relative rotation state.

[0107] The other end of the first connecting post 14 passes through the anti-jamming groove 13 and is movably sleeved on the outer surface of the second connecting post 16.

[0108] A spring 15 is fixed between the inner wall of the first connecting post 14 and the other end of the second connecting post 16.

[0109] In the specific implementation, when the guide column 20 slides along the inside of the guide groove 19, the lifting cover 17 is forced to have a lateral movement state of approaching and moving away from the lever 12, that is, the lifting cover 17 does not only follow the vertical reciprocating movement of the first connecting column 14, and the second connecting column 16 and the first connecting column 14 can provide conditions for the lateral and longitudinal movement of the lifting cover 17.

[0110] The two sides of the lifting cover 17 are fixed with the guide column 20;

[0111] The surface of the long plate 18 is provided with the guide groove 19;

[0112] The guide column 20 slides in the guide groove 19;

[0113] The guide groove 19 is composed of two groups of mutually parallel longitudinal sliding grooves and inclined grooves connected at both ends of the two groups of longitudinal sliding grooves;

[0114] The two groups of inclined grooves are distributed in a mirror image state.

[0115] In the specific implementation, as shown in the accompanying drawings Figure 11 and the accompanying drawings Figure 12 The orientation words in the following text are based on the perspective of the accompanying drawings Figure 11 and the accompanying drawings Figure 12 and do not represent fixed orientation. When the guide column 20 is at the upper end of the guide groove 19, the lowest point of the inclined groove at the upper end is near the lever 12, and the highest point is near the cylindrical protrusion 11. The guide column 20 moves clockwise inside the guide groove 19. After the guide column 20 reaches the highest point of the upper end inclined groove, if the lifting cover 17 moves downward at this time, the guide column 20 will move in a diagonal downward direction along the inside of the upper end inclined groove, thereby forcing the lifting cover 17 to separate from the cylindrical protrusion 11. Similarly, after the guide column 20 moves to the highest point of the lower end inclined groove, as the guide column 20 continues to move downward, the guide column 20 will move in a diagonal downward direction along the lower end inclined groove, forcing the lifting cover 17 to be held again below the cylindrical protrusion 11. It should be noted that the highest point of the upper end inclined groove and the connection between one of the longitudinal sliding grooves should be provided with an arc-shaped turning groove with a diameter larger than that of the guide column 20, and the lowest point of the lower end inclined groove and the connection between one of the longitudinal sliding grooves are provided with the same arc-shaped turning groove to assist the guide column 20 to maintain a clockwise rotation state. The design standard of the arc-shaped turning groove can refer to the existing mature technology, and the present application will not be described in detail here.

[0116] The two ends of the horizontal plate 9 are fixed with the cylindrical protrusion 11;

[0117] The inner diameter of the lifting cover 17 is larger than the outer diameter of the cylindrical protrusion 11;

[0118] The lifting cover 17 is movably sleeved on the outer surface of the cylindrical protrusion 11;

[0119] In practice, when the lifting cover 17 lifts the cylindrical protrusion 11, it can make better contact with the cylindrical protrusion 11. If the inner diameter of the lifting cover 17 is equal to the outer diameter of the cylindrical protrusion 11, it will obviously be easy to cause the lifting cover 17 and the cylindrical protrusion 11 to malfunction.

[0120] Limiting slide rods 10 are fixed at both ends of the horizontal plate 9 on the two side walls;

[0121] The side wall of the dust cover 8 is provided with three vertical grooves 31 corresponding to the positions of each set of limit slide rods 10;

[0122] The limiting slide bar 10 slides horizontally longitudinally inside the third longitudinal groove 31;

[0123] The top and bottom of the third vertical groove 31 are both higher than the top and bottom of the guide groove 19.

[0124] In practice, the horizontal plate 9 can maintain a vertical and stable reciprocating motion with the help of the limiting slide bar 10 and the third longitudinal groove 31, and is not easy to deviate. The third longitudinal groove 31 also limits the travel of the horizontal plate 9. Finally, the lowest point that the cylindrical protrusion 11 can move to is higher than the lowest point that the lifting cover 17 can move to, so that the lifting cover 17 can support the cylindrical protrusion 11. The highest point that the cylindrical protrusion 11 can move to is still higher than the highest point that the lifting cover 17 can move to, so that the lifting cover 17 can support the cylindrical protrusion 11 to rise throughout the entire process.

[0125] Lever 12 is designed in an L-shape;

[0126] In practice, the length of the lower end of the lever 12 is shorter than the length of the upper end, as shown in the attached figure. Figure 9 As shown, when one end of the lever 12 is pushed by the push rod 25 to rotate slightly, the other end of the lever 12 will rotate significantly. In this way, the reciprocating speed of the first connecting column 14 and the lifting cover 17 will be faster and the travel distance will be longer. As a result, the time from the elastic filter plate 7 rebounding to being bent again will be extremely short, so as not to affect the filtration efficiency.

[0127] The other end of the lever 12 is hinged to a slider 27;

[0128] Push rods 25 are fixed on both sides of the bottom of the sealing plate 22;

[0129] One end of the push rod 25 moves through the dust cover 8 and extends to the other end of the lever 12;

[0130] A second longitudinal groove 26 is provided on one end of the side wall of the push rod 25;

[0131] Slider 27 slides inside the second vertical groove 26;

[0132] In the embodiment, the push rod 25 moves horizontally, which will interfere with the rotation of the push rod 12. The cooperation between the slider 27 and the second vertical slot 26 makes the movement trajectory of the bottom end of the push rod 12 more suitable for the movement trajectory of the push rod 25 when the push rod 12 rotates, and the push rod 12 and the push rod 25 do not jam. When the push rod 25 moves horizontally, it can smoothly drive the push rod 12 to rotate. In addition, it should be noted that the slider 27 and the second vertical slot 26 can only move vertically, and they will not be separated. Therefore, when the push rod 25 reciprocates, it can pull or push the push rod 12.

[0133] A plurality of second springs 23 are fixed between the sealing plate 22 and the side wall of the processing box 2.

[0134] In the embodiment, the second spring 23 has two functions. On the one hand, it facilitates the resetting of the sealing plate 22. On the other hand, it increases the resistance when the sealing plate 22 moves towards the elastic filter plate 7, so that the sealing plate 22 will not be easily attracted by the dust fan when the elastic filter plate 7 is not severely clogged.

[0135] The size of the sealing plate 22 is consistent with the internal size of the processing box 2.

[0136] A plurality of through holes are formed in one side of the processing box 2 close to the sealing plate 22.

[0137] In the embodiment, the sealing plate 22 separates its two sides into two spaces that are not connected to each other. The sealing plate 22 is similar to a piston plate. When the elastic filter plate 7 is severely clogged and the airflow is difficult to pass through the filter holes 32 under the continuous work of the dust fan, the air pressure between the elastic filter plate 7 and the sealing plate 22 rapidly decreases, and the sealing plate 22 will be forced to be attracted to the exhaust cylinder 4. When the sealing plate 22 moves, the through holes can provide an air inlet channel for the space on the side of the sealing plate 22 away from the elastic filter plate 7, so as to prevent air pressure imbalance and prevent the exhaust cylinder 4 from attracting the sealing plate 22.

[0138] The dust collection assembly further comprises a dust blocking plate 29 fixed to one side of the inner wall of the dust collection box 5, and a trapping plate 30 fixed to the other side of the inner wall of the dust collection box 5.

[0139] The top end of the dust collection box 5 is connected with an air suction pipe 28, and the other end of the air suction pipe 28 is connected and inserted into the lower end of the exhaust cylinder 4.

[0140] In the embodiment, as shown in the attached drawings, Figure 3As shown, the inner diameter of the suction pipe 28 is relatively thin, only a little wind power of the dust fan is needed, too large suction force will cause the dust entering the dust collection box 5 to be sucked to the exhaust cylinder 4, and too small suction force will cause the dust falling into the channel shell 6 to be easily raised again, so the inner diameter of the suction pipe 28 will determine the suction force to some extent, and the appropriate size of the suction pipe 28 can be selected according to the needs, of course, this is a common method in the prior art, and the appropriate size of the suction pipe 28 can be selected by referring to the prior art. It should be noted that the suction pipe 28 can be located in the middle of the top of the dust collection box 5, or a little left, but not right, so as to prevent the airflow from wrapping the dust vertically rising from the gap between the dust blocking plate 29 and the bottom end of the interception plate 30.

[0141] The channel shell 6 is connected between the treatment box 2 and the dust collection box 5 in an arc shape, and the inside of the channel shell 6 is smooth without corners;

[0142] The bottom end of the channel shell 6 is located at the upper end of one side of the dust collection box 5;

[0143] The width of the dust blocking plate 29 is consistent with the inner wall width of the dust collection box 5;

[0144] The dust blocking plate 29 is in an inclined state, and the top of the dust blocking plate 29 is located above the bottom end of the channel shell 6;

[0145] The bottom of the dust blocking plate 29 is close to the interception plate 30, but there is a clear gap between the dust blocking plate 29 and the interception plate 30;

[0146] The width of the interception plate 30 is completely consistent with the inner wall width of the dust collection box 5;

[0147] The bottom of the interception plate 30 is lower than the bottom of the dust blocking plate 29;

[0148] The height of the interception plate 30 is less than the inner wall height of the dust collection box 5;

[0149] One side of the interception plate 30 is completely attached to the inner wall of the dust collection box 5 without gaps.

[0150] In a specific implementation, the dust and part of the airflow first hits the dust baffle 29 after entering the dust collection box 5 from the channel shell 6. The airflow is upward, so the airflow carrying the dust goes upward and is blocked by the dust baffle 29, and finally moves along the lower surface of the dust baffle 29. In this process, the dust falls to the lower part of the dust collection box 5 due to the influence of gravity, and most of the airflow continues to move to the right due to inertia, bypasses the lower surface of the dust baffle 29, and reaches the right side area of the dust collection box 5. When the airflow moving to the right reaches the vicinity of the right side wall of the dust collection box 5, it flows downward along the right side wall of the dust collection box 5 due to the "wall effect", which is a basic phenomenon of fluid mechanics. When the airflow flows downward along the right side wall to the bottom end of the interception plate 30, it is completely blocked by the bottom edge of the interception plate 30, and the wall effect is invalid. According to the fluid "flowing principle", the airflow makes a one-hundred-and-eighty-degree turn at the bottom edge of the interception plate 30, from "flowing downward" to "flowing leftward + upward", enters the space on the left side of the interception plate 30, and is guided upward by the suction pipe 28. The two airflows finally converge at the upper part of the dust collection box 5 and are discharged from the suction pipe 28. The interception plate 30 in the present application mainly functions to intercept the airflow, destroy the "wall effect", and make the airflow not contact the dust in the lower end of the dust collection box 5 as much as possible.

[0151] A dust removal method for a slag spilling machine, the dust removal method comprising the following steps:

[0152] S1, when a large amount of dust is blocked in the surface of the elastic filter plate 7 and the third longitudinal groove 31, the gas is difficult to pass through the elastic filter plate 7, and under the continuous work of the dust suction fan, the air pressure between the elastic filter plate 7 and the sealing plate 22 decreases, and the sealing plate 22 is passively sucked to be close to the elastic filter plate 7;

[0153] S1-1, the displacement of the sealing plate 22 triggers the rotation of the lever 12 and forces the first connecting column 14 to vertically move downward. When the first connecting column 14 starts to move downward, it first quickly separates the lifting cover 17 from the cylindrical protrusion 11, so that the horizontal plate 9 first rapidly falls with the lifting cover 17 under the rebound pull of the third spring 24, and soon makes the elastic filter plate 7 rebound to restore. The vibration impact force of the elastic filter plate 7 when rebounding suddenly pushes the dust attached to the surface of the elastic filter plate 7 and the dust blocked in the third longitudinal groove 31 away from the elastic filter plate 7, and the lifting cover 17 falls to the obliquely downward of the cylindrical protrusion 11 and is affected by the guide groove 19 to move to the position directly below the cylindrical protrusion 11 again;

[0154] S1-2, the dust in the elastic filter plate 7 is bounced off, the gas enters the processing box 2 again from the air inlet cover 3, the air pressure between the elastic filter plate 7 and the sealing plate 22 rises, the sealing plate 22 is reset under the rebound of the second spring 23, the sealing plate 22 triggers the push rod 12 again to rotate reversely, the first connecting column 14 quickly moves up, the lifting cover 17 lifts the cylindrical protrusion 11 to move up synchronously and quickly, and the elastic filter plate 7 is extruded to be forced to bend, and waits for the next release;

[0155] S2, in step S1, when the dust in the elastic filter plate 7 is bounced off and falls into the channel shell 6, a small part of wind power generated by the dust collection fan is transmitted to the dust collection box 5 through the air suction pipe 28, so that the dust collection box 5 and the channel shell 6 are always in a state of micro-low air pressure, the dust falling into the channel shell 6 is not easy to rise again, but is sucked into the dust collection box 5, and the dust is concentrated in the inside of the lower end of the dust collection box 5 under the blockage and guidance of the dust blocking plate 29 and the guide column 20, and the filtered gas is discharged from the exhaust cylinder 4 after being combined with the filtered gas in the processing box 2.

[0156] Working principle: when the dust removal device and dust removal method are used, first of all, the dust generated by the slagging equipment 1 during work is sucked into the processing box 2 through the air inlet cover 3 under the action of the dust collection fan, when the filter hole 32 is not seriously blocked, the airflow can pass through the filter hole 32 smoothly and be discharged from the exhaust cylinder 4, and the dust is blocked by the elastic filter plate 7, after a long time of use, most of the dust will adhere to the surface of the elastic filter plate 7, and a small part of the dust may be stuck in the filter hole 32, causing the channel available for airflow to pass through to become smaller and smaller, and the air pressure between the elastic filter plate 7 and the sealing plate 22 becomes lower, when the filter hole 32 is seriously blocked, the airflow passing through the filter hole 32 is very difficult, and the dust collection fan always maintains constant power to suck the airflow, the sealing plate 22 is forced to be sucked to the exhaust cylinder 4 and stretch the second spring 23, the sealing plate 22 moves the push rod 25, the push rod 25 pushes the push rod 12, the push rod 12 starts to rotate, and the first connecting column 14 quickly moves down under the pressure of the anti-jamming groove 13, when the first connecting column 14 starts to move down, the first connecting column 14 first drives the second connecting column 16, the lifting cover 17 and the guide column 20 to move down, the guide column 20 moves to the oblique lower side under the influence of the guide groove 19 and separates the lifting cover 17 from the cylindrical protrusion 11, the second connecting column 16 is inserted into the deep part of the first connecting column 14 and extrudes the first spring 15, the cylindrical protrusion 11 loses the limitation of the lifting cover 17 and quickly moves down under the rebound of the third spring 24, providing space for the rebound of the elastic filter plate 7, when the elastic filter plate 7 rebounds suddenly, on the one hand, the vibration generated thereby shakes off the dust adhering to the surface thereof into the channel shell 6, and on the other hand, the dust stuck in the filter hole 32 is finally dropped into the channel shell 6 due to the slight extrusion of the filter hole 32 and the inertia lag.

[0157] When the horizontal plate 9 moves down rapidly, the first connecting column 14 and the lifting cover 17 also move down rapidly, until the guide column 20 moves to the lower end of the guide slot 19, and is affected by the track of the guide slot 19 and the rebound of the first spring 15, the guide column 20 moves obliquely downward, the second connecting column 16 and the lifting cover 17 also move obliquely downward passively, the lifting cover 17 is re-supported under the cylindrical protrusion 11, after the dust in the filter hole 32 is cleaned, sufficient airflow passes through the filter hole 32 again, the air pressure between the elastic filter plate 7 and the sealing plate 22 returns to normal, the exhaust cylinder 4 has no great adsorption force on the sealing plate 22, under the rebound of the second spring 23, the sealing plate 22 drives the push rod 25 to move rapidly to the original position, the push rod 25 pulls the sliding block 27 and the push rod 12 to move reversely, the other end of the push rod 12 rapidly lifts the first connecting column 14, so that the lifting cover 17 supports the cylindrical protrusion 11 to move up rapidly, and re-bends the elastic filter plate 7. The dust falling into the channel shell 6 is sucked into the dust collection box 5, and is affected by the air suction pipe 28 and the dust baffle 29, and finally falls into the lower space of the dust collection box 5, a small amount of airflow passes from the air suction pipe 28 to the exhaust cylinder 4 to be exhausted, and the dust can be cleaned out by opening the dust outlet of the dust collection box 5 regularly.
