Description

Technical Field

[0001] The present invention relates to the technical field of waste recycling, and particularly to a resource processing technology and equipment for waste steel recycling and reuse. Background Art

[0002] In the production of steel mills, high-value metal particles such as steel slag particles, iron particles, and iron crystal powder exist in the flue gas of steel smelting. Therefore, it is necessary to treat the flue gas of steel smelting to recover high-value metal particles. After recovery, the metal particles are reprocessed to produce waste steel compacts suitable for secondary melting.

[0003] The following problems exist in the prior art:

[0004] In the existing flue gas filtration and separation of metal particles, the flue gas is introduced into a dedicated dust removal and filtration device such as a bag filter. The gas and the metal particles inside are separated by the dust collector. However, the existing filtration device often adopts the process of introducing air from the bottom side and exhausting air from the top after filtering the flue gas through the filter bag.

[0005] The flue gas entering the dust collector will first impact the filter bags closest to the air inlet. These filter bags bear the greatest air flow load, while the filter bags far from the air inlet bear a relatively smaller load. This leads to uneven air flow distribution, causing the filter bags near the air inlet to be more severely worn due to the impact of high-pressure air flow for a long time. At the same time, the pressure difference of these filter bags will be relatively high, further affecting the stability and efficiency of the system. Moreover, the filter bags near the air inlet are more likely to accumulate dust, while the filter bags far away may not be fully utilized due to insufficient air flow, resulting in a decrease in the overall filtration efficiency. After the filter bags are dust-laden, the pulse device is activated to compress air to impact the filter bags for dust removal. If the temperature of the gas ejected by the pulse compressed air is different from the temperature inside the equipment, it will cause the filter bags to condense and stick, further affecting the overall filtration effect.

On the side of the second cross plate opposite to the central column, a linkage ring is fixedly connected. The linkage ring is movably connected through a card slot and a concave block.

[0029] As a preferred embodiment of the waste steel recycling and resource processing equipment described in the present invention, the following is provided: the bottom of the central column is fixedly connected with a pressing plate. The outer side of the pressing plate is slidably connected to the inner wall of the treatment chamber. The surface of the pressing plate is annularly provided with movable openings. The movable openings are movably connected through a card slot and a concave block. The surface of the pressing plate is evenly distributed with a plurality of filter layers;

[0030] A blocking plate is installed on the top of the third cross plate. A sliding groove is extended inwardly from the opening groove. The sliding groove is slidably connected to the blocking plate.

[0031] Advantages of the present invention:

[0032] First, through the internal and external clamping design of the inner support column and the insertion rod, the filter bag forms a convex part that rotates and stirs the internal air flow distribution in the treatment chamber. While the convex part stirs the air flow, it increases the air flow contact area, so that the air flow particles are evenly distributed inside the treatment chamber by the rotating filter bag. During the rotation of the filter bag, the centrifugal force of its own rotation will loosen some of the particles on its surface. Combining the impact vibration of the inner cross plate inside the filter bag and the up and down scraping of the scraping plate and the concave block on the surface of the filter bag, the surface of the filter bag is not easily attached with particles. The pressing plate that moves up and down outside the filter bag, during its up and down movement, pulls the scraping plate and the concave block to scrape and clean the surface of the filter bag, and at the same time, the particles scraped by the filter bag are pushed down and precipitated by the pressing plate, reducing the secondary dust attachment after the attachment on the surface of the filter bag is scraped off. Moreover, the up and down movement of the pressing plate will vertically disturb the air flow rotated and disturbed by the convex part of the filter bag, making the air flow distribution more uniform.

[0033] II. By starting the air extraction component, the air extraction component continuously extracts the gas inside the flue into the inside of the treatment chamber. After the gas enters the inside of the treatment chamber, start the rotary drive component, so that the rotary drive component drives the active component to rotate through the transmission gear at its bottom, and the active component drives the driven component to rotate during rotation, so that during the rotation of the driven component, through the connection of the connecting column, the pressing plate, the collar plate and the mounting block, the insertion rod and the inner support column are driven to rotate with the driven component, so that the filter bag clamped between the insertion rod and the inner support column also rotates accordingly. During the rotation of the filter bag, the convex part on its side stirs the air inside the treatment chamber during the rotation of the filter bag, making the gas inside the treatment chamber more evenly distributed under the stirring of the convex part following the filter bag, reducing the installation positions of the inlet pipes, resulting in different filtration and separation loads of the filter bags at different positions, and thus the problems of wear and filtration efficiency are generated.

[0034] III. Through the internal and external clamping design of the inner support column and the insertion rod, concave parts and convex parts are formed on the inner and outer sides of the surface of the filter bag, thus increasing the contact area between the surface of the filter bag and the airflow inside the treatment chamber. On the side of the convex part, during the rotation of the convex part following the filter bag, the side of the convex part continuously impacts the soot inside the treatment chamber, improving the filtration efficiency of the filter bag. Moreover, the convexity of the convex part will increase the degree of agitation when the filter bag rotates centrifugally and contacts the air, making it difficult for the particulate matter in the flue gas to adhere to the surface of the filter bag.

[0035] IV. During the process of the filter bag rotating to make the airflow uniform, start the reciprocating pushing source regularly, so that the output shaft of the reciprocating pushing source pushes the cross plate I, the central column and the outer connecting column downward. During the process of the output shaft of the reciprocating pushing source pushing downward, the rotary drive component drives the rotational speed of the driven component and the filter bag to decrease or stop, facilitating the precipitation of particulate matter in the airflow inside the treatment chamber.

[0036] V. During the downward movement of the outer connecting column, the inner cross plate at its bottom will approach the cross plate III along the inner support column and finally impact the surface of the cross plate III, causing the cross plate III to drive the inner support column and the filter bag outside the inner support column to vibrate. Therefore, the whole filter bag is vibrated internally. During the process of the filter bag rotating centrifugally and the convex part guiding the air to agitate and impact its side, the particulate matter attached to the surface of the filter bag will become loose. Combined with the impact vibration generated by the inner cross plate impacting the cross plate III, the loose particulate matter is impacted and loosened and falls into the inside of the collection chamber for precipitation collection, so that under the combined action of the filter bag rotating centrifugally to loosen the particulate matter attached to the surface and the internal vibration, the particulate matter attached to the whole surface of the filter bag is further reduced.

[0037] 6. The downward movement of the central column will drive the linkage ring and the scraping plate that rotates synchronously with the filter bag inside the linkage ring to move downward synchronously through the cross plate II. During this process, the rotation driving member drives the rotation speed of the driven member and the filter bag to decrease or stop, so that the scraping plate moves downward along the insertion rod through the scraping plate and the concave block, and the scraping plate and the concave block scrape the outer surface of the filter bag, thereby reducing the condensation and bag sticking on the surface of the filter bag, further improving the adhesion of particulate matter on the surface of the filter bag, keeping the filtration efficiency of the filter bag relatively stable, and further scraping the contact surface between the filter bag and the particulate matter on the basis of the rotation and centrifugal loosening of the surface-attached particles and the internal vibration of the filter bag, thereby improving the separation and treatment effect of the filter bag on flue gas particulate matter.

[0038] 7. The central column can scrape the inner wall of the treatment chamber to reduce the attachments on its surface by driving the pressing and discharging plate to move up and down, and the pressing and discharging plate that reciprocates up and down can regularly re-distribute the uniformly flowing air of the filter bag in its internal moving port, so that the pressing and discharging plate moving up and down will generate vertical disturbances, making the flue gas distribution above and below the filter bag more uniform. Therefore, the vertical disturbances of the pressing and discharging plate and the rotational disturbances of the filter bag through the convex part further improve the uniform distribution of the airflow inside the treatment chamber.

[0039] 8. The cross plate III separates the interior of the convex part through the blocking plate at its top, and there is an exhaust space between the blocking plate and the filter bag. The blocking plate blocks and guides the air passing through the filter bag, thereby increasing the air flow rate of the filter bag rotating and stirring under the internal support and blocking of the blocking plate, and further improving the degree of the filter bag rotating and stirring the uniform air flow under the internal support and blocking of the blocking plate.

[0040] 9. Replace the cross plate II with the pressing and discharging plate. When the central column drives the pressing and discharging plate to move downward, the rotation driving member drives the rotation speed of the driven member and the filter bag to decrease or stop. The pressing and discharging plate drives the flue gas particles at its bottom to move downward through the filter layer on its surface and approach the collection chamber, making the flue gas particles at the bottom of the pressing and discharging plate easier to precipitate inside the collection chamber under its push. And through the regular downward pressing and pushing cleaning of the pressing and discharging plate, the particulate matter in the airflow inside the treatment chamber will not agglomerate excessively, keeping the content of flue gas particulate matter in contact with the filter bag relatively stable for a certain period of time. And the downward movement of the pressing and discharging plate will also drive the scraping plate and the concave block inside it to move downward through the moving port, so that the scraping plate and the concave block clean the surface of the filter bag, and part of the particle attachments scraped by the scraping plate will be pushed downward by the downward moving pressing and discharging plate to precipitate, reducing the secondary dust generation after the surface of the filter bag is cleaned, and improving the filtration and separation effect of the filter bag after the downward movement and cleaning of the pressing and discharging plate.

The pressing plate 2024 presses the fixing sleeve portion 2033 onto the top of the collar plate 2072 through the gasket 2023. The insertion rod 205 presses the fixing sleeve portion 2033 on its top to be threadedly connected to the opening on the surface of the mounting block 2075.

[0086] Specifically, as Figure 7 and 9 shown in Fig. -12, a scraping plate 204 is movably connected to the surface of the recessed portion 2032. Concave blocks 2042 are arranged between adjacent scraping plates 204. The concave blocks 2042 are movably arranged on the surface of the protruding portion 2031;

[0087] The middle of the scraping plate 204 is slidably connected to the surface of the inner one of the set of insertion rods 205 through a bayonet 2041. The outer insertion rod 205 of the set of insertion rods 205 is movably connected to the opening in the middle of the scraping plate 204. Preferably, a high-temperature resistant rubber layer is provided on the contact surfaces of the scraping plate 204 and the concave blocks 2042 with the filter bag 203. A card slot 20421 is formed on the outer side of the concave block 2042.

[0088] It should be noted that the air extraction member 1023 is preferably an air extraction pump, the rotary drive member 1026 is preferably a three-phase asynchronous reduction motor, and the reciprocating push source 1031 is preferably a cylinder or an electric telescopic cylinder. The above devices are controlled by a unified PLC and powered by an external energy source.

[0089] Operation process:

[0090] Preparation before treatment: By docking the air inlet pipe 1021 to the flue of the steelmaking furnace, when the air extraction member 1023 is started, the gas inside the collection chamber 101, the treatment chamber 102, and the discharge chamber 103 is extracted, so that the air inside the flue enters the bottom of the treatment chamber 102 through the air inlet pipe 1021. After being processed and separated by the filter bag 203, it is then transported to the subsequent purification step through the exhaust pipe 1022 and the air extraction member 1023;

[0091] Among them, the filter bag 203 is sleeved on the surfaces of the inner struts 207 and the cross plate three 2071, and the filter bag 203 between adjacent inner struts 207 is pushed inward by the inner rods 205 of a group of inserting rods 205 to form a recessed portion 2032. The two adjacent inner rods 205 will push and pull the filter bag 203 inward to form a recessed portion 2032, causing the inner strut 207 between the adjacent recessed portions 2032 to be lifted to form a convex portion 2031. After the recessed portion 2032 and the convex portion 2031 are formed, the top of the inserting rod 205 pushes the sleeve fixing portion 2033 at its top position to be inserted into the opening on the surface of the mounting block 2075 for threaded connection, and the remaining sleeve fixing portions 2033 pass through the through cavity 2073 and are clamped into the inside of the flanging cavity 2074. After the gasket 2023 is clamped between the pressing plate 2024 and the collar plate 2072, the filter bag 203 clamped by the inner strut 207 and the inserting rod 205 is inserted into the inside of the mounting port 10241 and passes through the scraping plate 204 and the concave block 2042. After the filter bag 203 is inserted into the inside of the mounting port 10241, the pressing plate 2024 is fixed to the surface of the connecting column 2021 by a nut, so that the gasket 2023 is pressed by the pressing plate 2024 between the pressing plate 2024 and the follower 202. Then, when the follower 202 rotates, through the connection of the connecting column 2021 and the pressing plate 2024, the collar plate 2072 and the inner struts 207 and the inserting rods 205 at the bottom of the mounting block 2075 can be driven to rotate accordingly;

[0092] After the filter bag 203 passes through the mounting port 10241, the scraping plate 204 and the concave block 2042, and after the pressing plate 2024 and the connecting column 2021 are fixed, the installation of the filter bag 203 inside the processing chamber 102 is completed. At this time, the scraping plate 204 and the concave block 2042 are arranged outside the filter bag 203, the inner cross plate 206 is arranged inside the filter bag 203, the central column 1033 and the outer connecting column 1034 are installed with the cross plate one 1032, the output shaft of the reciprocating pushing source 1031 is inserted into the cross plate one 1032, and then the opened discharge chamber 103 is clamped and closed to the top of the processing chamber 102.

[0093] Formal treatment: By starting the air extraction member 1023, the air extraction member 1023 continuously extracts the gas inside the flue into the interior of the treatment chamber 102. After the gas enters the interior of the treatment chamber 102, start the rotary drive member 1026, so that the rotary drive member 1026 drives the active member 201 to rotate through the transmission gear 10261 at its bottom, and the active member 201 drives the driven member 202 to rotate during rotation, so that during the rotation of the driven member 202, through the connection of the connecting column 2021, the pressing plate 2024, the collar plate 2072 and the mounting block 2075, the insertion rod 205 and the inner support column 207 are driven to rotate with the driven member 202, so that the filter bag 203 clamped between the insertion rod 205 and the inner support column 207 also rotates accordingly. During the rotation of the filter bag 203, the convex portion 2031 on its side stirs the air inside the treatment chamber 102 during the rotation of the filter bag 203, so that the gas inside the treatment chamber 102 is more evenly distributed under the agitation of the convex portion 2031 following the filter bag 203, reducing the installation position of the intake pipe 1021, resulting in different filtration separation loads of the filter bags 203 at different positions, thereby causing wear and filtration efficiency problems. In order to make the filter bag 203 clamped between the insertion rod 205 and the inner support column 207 tighter after forming the convex portion 2031 and the concave portion 2032, the inner diameter of the filter bag 203 is matched with the diameter of the cross plate three 2071;

[0094] Through the internal and external clamping design of the inner support column 207 and the insertion rod 205, concave portions 2032 and convex portions 2031 on the inner and outer sides are formed on the surface of the filter bag 203, thereby increasing the contact area between the surface of the filter bag 203 and the airflow inside the treatment chamber 102. On the side of the convex portion 2031, during the rotation of the convex portion 2031 following the filter bag 203, the side of the convex portion 2031 continuously impacts the soot inside the treatment chamber 102, improving the filtration efficiency of the filter bag 203, and the convexity of the convex portion 2031 will increase the agitation degree of the filter bag 203 in contact with the air during rotational centrifugation, making it difficult for the particulate matter inside the flue gas to adhere to the surface of the filter bag 203;

[0095] During the process of the filter bag 203 rotating to evenly distribute the airflow, the reciprocating push source 1031 is started regularly, so that the output shaft of the reciprocating push source 1031 pushes the cross plate one 1032, the central column 1033 and the outer connecting column 1034 downward. During the process of the output shaft of the reciprocating push source 1031 pushing downward, the rotary drive member 1026 drives the driven member 202 and the filter bag 203 to reduce the rotation speed or stop, facilitating the precipitation of particulate matter in the airflow inside the treatment chamber 102;

[0096] During the downward movement of the external connecting column 1034, the inner cross plate 206 at its bottom will approach the cross plate three 2071 along the inner support column 207 and finally impact the surface of the cross plate three 2071, causing the cross plate three 2071 to drive the inner support column 207 and the filter bag 203 outside the inner support column 207 to vibrate. Therefore, the entire filter bag 203 is subjected to internal vibration. During the process of the rotational centrifugation of the filter bag 203 and the air turbulence caused by the convex portion 2031 guiding the impact on its side surface, the particulate matter attached to the surface of the filter bag 203 will become loose. Combining with the impact vibration generated by the inner cross plate 206 impacting the cross plate three 2071, the loose particulate matter is impacted and loosened and falls into the interior of the collection chamber 101 for sedimentation collection. Thus, under the combined action of the rotational centrifugation of the filter bag 203 to loosen the particulate matter attached to the surface and the internal vibration, the particulate matter attached to the overall surface of the filter bag 203 is further reduced;

[0097] Such as Figures 6 - 7 , and the downward movement of the central column 1033 will drive the linkage ring 10332 and the scraping plate 204 that rotates synchronously with the filter bag 203 inside the linkage ring 10332 to move downward synchronously through the cross plate two 10331. During this process, the rotational drive member 1026 drives the rotational speed of the driven member 202 and the filter bag 203 to decrease or stop, causing the scraping plate 204 to move downward along the insertion rod 205 through the scraping plate 204 and the concave block 2042, and the scraping plate 204 and the concave block 2042 scrape the outer surface of the filter bag 203, thereby reducing the situation of dew condensation and bag sticking on the surface of the filter bag 203, further improving the adhesion of particulate matter on the surface of the filter bag 203, keeping the filtration efficiency of the filter bag 203 relatively stable, and further scraping the contact surface between the filter bag 203 and the particulate matter on the basis of the rotational centrifugation of the filter bag 203 to loosen the particulate matter attached to the surface and the internal vibration, thereby improving the separation and treatment effect of the filter bag 203 on flue gas particulate matter.

[0098] The central column 1033 can scrape the inner wall of the treatment chamber 102 to reduce the attachments on its surface by driving the pressure discharge plate 10333 to move up and down. Moreover, the reciprocating up and down movement of the pressure discharge plate 10333 can periodically re - distribute the uniformly flowing air of the filter bag 203 rotating in the internal movable port 10334, causing the vertically moving pressure discharge plate 10333 to generate vertical disturbances, making the flue gas distribution above and below the filter bag 203 more uniform. Thus, the vertical disturbances of the pressure discharge plate 10333 and the rotational disturbances of the filter bag 203 through the convex portion 2031 further improve the uniform distribution of the internal air flow in the treatment chamber 102.

[0099] Example three: This example refers to Figures 2 - 19 shown. The difference between this example and the above examples is:

[0100] Specifically, as Figure 8 shown and Figure 19As shown, a pressing plate 10333 is fixedly connected to the bottom of the central column 1033. The outer side of the pressing plate 10333 is slidably connected to the inner wall of the processing chamber 102. An activity port 10334 is annularly arranged on the surface of the pressing plate 10333. The activity port 10334 is movably connected through a clamping groove 20421 and an inwardly concave block 2042. A plurality of filter layers are evenly distributed on the surface of the pressing plate 10333. The material of the filter layer is the same as that of the filter bag 203, both being a filter cloth bag made of polyphenylene sulfide or polytetrafluoroethylene, and the filter layer does not overlap with the activity port 10334 and does not contact the inner wall of the processing chamber 102;

[0101] A blocking plate 2076 is installed at the top of the cross plate three 2071. A sliding groove 2062 is extended inwardly from the opening groove 2061. The sliding groove 2062 is slidably connected to the blocking plate 2076.

[0102] All other structures are the same as those in the first and second embodiments.

[0103] Operation process:

[0104] As an improved solution for the rotation of the filter bag 203, as Figure 19 shown, the cross plate three 2071 separates the inside of the protruding part 2031 through the blocking plate 2076 at its top, and there is an exhaust space between the blocking plate 2076 and the filter bag 203. The blocking plate 2076 blocks and guides the air passing through the filter bag 203, so as to increase the air flow rate of the rotational agitation of the filter bag 203 under the internal support and block of the blocking plate 2076, and further improve the degree of uniform air flow rotation and agitation of the filter bag 203 under the internal support and block of the blocking plate 2076.

[0105] As Figure 8As shown in the figure, replace the cross plate II 10331 with the pressing and discharging plate 10333. When the central column 1033 drives the pressing and discharging plate 10333 to move downward, the rotation driving part 1026 drives the speed of the driven part 202 and the filter bag 203 to decrease or stop. The pressing and discharging plate 10333 drives the flue gas particles at its bottom to move downward through the filter layer on its surface towards the collection chamber 101, so that the flue gas particles at the bottom of the pressing and discharging plate 10333 are more likely to precipitate inside the collection chamber 101 under its push. And through the regular downward pressing and pushing cleaning of the pressing and discharging plate 10333, the particulate matter in the airflow inside the treatment chamber 102 will not accumulate excessively, so that the content of flue gas particulate matter in contact with the filter bag 203 remains relatively stable for a certain period of time. Moreover, when the pressing and discharging plate 10333 moves downward, it will also drive the scraping plate 204 and the concave block 2042 inside it to move downward through the movable port 10334, so that the scraping plate 204 and the concave block 2042 clean the surface of the filter bag 203. Part of the particulate attachments scraped by the scraping plate 204 will be pushed downward and precipitated by the downward moving pressing and discharging plate 10333, reducing the secondary dust raising after the surface of the filter bag 203 is cleaned, and improving the filtering and separating effect of the filter bag 203 after being cleaned by the downward movement of the pressing and discharging plate 10333.

[0106] To sum up: Through the internal and external clamping design of the inner support column 207 and the insertion rod 205, a convex part 2031 is formed on the filter bag 203 to rotate and stir the airflow distribution inside the treatment chamber 102. While the convex part 2031 stirs the airflow, it increases the airflow contact area, so that the airflow particles are evenly distributed inside the treatment chamber 102 by the rotating filter bag 203. During the rotation of the filter bag 203, its own rotational centrifugal force will loosen some particulate matter on its surface. Combining with the impact vibration of the inner cross plate 206 inside the filter bag 203 and the up and down scraping of the scraping plate 204 and the concave block 2042 on the surface of the filter bag 203, it is not easy for particulate matter to adhere to the surface of the filter bag 203. The pressing and discharging plate 10333 that moves up and down outside the filter bag 203, during its up and down movement, while pulling the scraping plate 204 and the concave block 2042 to scrape and clean the surface of the filter bag 203, makes the particulate matter scraped from the filter bag 203 be pushed down and precipitated by the pressing and discharging plate 10333, reducing the secondary dust raising adhesion after the surface attachments of the filter bag 203 are scraped off. And the up and down movement of the pressing and discharging plate 10333 will vertically disturb the airflow rotated and disturbed by the filter bag 203 through the convex part 2031, making the airflow distribution more uniform.
