Description

Technical Field

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

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

[0003] The prior art has the following problems: The existing flue gas filtration and separation of metal particles will cause the flue gas to enter a special dust removal and filtration device such as a bag filter, and the gas and the metal particles inside it will be separated by the dust collector. However, the existing filtration equipment often uses the bottom side intake, and then the flue gas is filtered by the filter bag and then exhausted from the top; The flue gas entering the dust collector will first impact the filter bags closest to the air inlet. These filter bags bear the greatest airflow load, while the filter bags far from the air inlet are relatively lightly loaded, resulting in uneven airflow distribution. The filter bags near the air inlet will suffer from increased wear due to long-term impact of high-pressure airflow. At the same time, the pressure difference of these filter bags will be higher, further affecting the stability and efficiency of the system. The filter bags near the air inlet are more prone to dust accumulation, while the filter bags far away may not be fully utilized due to insufficient airflow, resulting in reduced overall filtration efficiency. After dust accumulates on the filter bags, the pulser compressed air will be started 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 condensation on the filter bags and stick them, further affecting the overall filtration effect.

[0014] As a preferred solution of the waste steel recycling and resource processing equipment described in the present invention, wherein: a pressure plate is fixedly connected to the bottom of the central column, the outer side of the pressure plate is slidably connected to the inner wall of the processing chamber, the surface of the pressure plate is ring-arranged with a movable opening, the movable opening is movably connected through a slot and an inner concave block, and a plurality of filter layers are evenly distributed on the surface of the pressure plate; A blocking plate is installed on the top of the cross plate three, and a sliding groove is extended inwardly from the opening groove, and the sliding groove is slidably connected with the blocking plate.

[0015] Beneficial effects of the present invention: 1. Through the internal and external clamping design of the inner support and the insertion rod, the filter bag forms a convex part which rotates and stirs the airflow distribution inside the processing chamber. The convex part increases the airflow contact area while stirring the airflow, so that the airflow particles are evenly distributed inside the processing chamber by the rotating filter bag, and during the rotation of the filter bag, its own rotating centrifugal force will loosen some particles on its surface, and combined with the impact vibration of the inner cross plate inside the filter bag and the up and down scraping of the scraper plate and the inner concave block on the surface of the filter bag, it is difficult for particles to adhere to the surface of the filter bag. The pressure plate which is arranged on the outer side of the filter bag and moves up and down, when it moves up and down, pulls the scraper plate and the inner concave block to scrape and clean the surface of the filter bag, and the particles scraped by the filter bag are pushed down and precipitated by the pressure plate, thereby reducing the secondary dust attachment after the attachments on the surface of the filter bag are scraped off, and the up and down movement of the pressure plate will vertically disturb the airflow of the filter bag disturbed by the rotation of the convex part, so that the airflow distribution is more uniform.

[0016] Second, by starting the vacuum component, the vacuum component continuously draws the gas inside the flue into the interior of the processing chamber. After the gas enters the interior of the processing chamber, the rotary drive component is started, so that the rotary drive component drives the active component to rotate through the transmission gear at its bottom, so that the active component drives the driven component to rotate during the rotation, so that during the rotation of the driven component, through the connection of the connecting column, the pressure plate, the ring plate and the mounting block, the plug rod and the inner support are driven to rotate with the driven component, so that the filter bag clamped between the plug rod and the inner support also rotates accordingly, and during the rotation of the filter bag, the raised part on the side of the filter bag stirs the air inside the processing chamber during the rotation of the filter bag, so that the gas inside the processing chamber is more evenly distributed under the stirring of the raised part along with the filter bag, thereby reducing the installation position of the air inlet pipe, resulting in different filtering and separation loads of the filter bags at different positions, thereby causing wear and filtering efficiency problems.

[0017] 3. Through the internal and external clamping design of the inner support and the insertion rod, the surface of the filter bag forms inner and outer depressions and protrusions, thereby increasing the contact area between the filter bag surface and the airflow inside the processing chamber, and the side of the protrusion will continuously hit the smoke and dust inside the processing chamber as the protrusion rotates with the filter bag, thereby improving the filtration efficiency of the filter bag. The protrusion of the protrusion will increase the degree of agitation of the filter bag in contact with the air when the filter bag rotates centrifugally, making it difficult for particles in the smoke to adhere to the surface of the filter bag.

[0018] 4. In the process of the filter bag rotating to even out the airflow, the reciprocating propulsion source is started at a fixed time so that the output shaft of the reciprocating propulsion source pushes the cross plate 1, the center column and the outer connecting column to move downward, and in the process of the output shaft of the reciprocating propulsion source pushing downward, the rotating driving member drives the driven member and the filter bag to reduce or stop the speed, so as to facilitate the precipitation of particulate matter in the airflow inside the processing chamber.

[0019] 5. During the downward movement of the outer connecting column, the inner cross plate at its bottom will approach cross plate three along the inner support and finally hit the surface of cross plate three, so that cross plate three drives the inner support and the filter bag outside the inner support to vibrate, thereby causing the filter bag as a whole to be subjected to internal vibration. In the process of the filter bag's rotation and centrifugation and the raised part guiding the air to impact its side, the particles attached to the surface of the filter bag will be loosened. Combined with the impact vibration generated by the inner cross plate hitting cross plate three, the loosened particles will be loosened and fall into the collection chamber for sedimentation and collection. Therefore, under the combined effect of the particles attached to the surface of the filter bag loosened by rotation and centrifugation and the internal vibration, the particles attached to the overall surface of the filter bag are further reduced.

[0020] 6. The downward movement of the center column will drive the linkage ring and the scraper plate inside the linkage ring that rotates synchronously with the filter bag to move downward synchronously through the cross plate 2. In this process, the rotating drive member drives the driven member and the filter bag to reduce or stop the rotation speed, so that the scraper plate moves downward along the insertion rod through the scraper plate and the inner concave block, and the scraper plate and the inner concave block scrape the outer surface of the filter bag, thereby reducing condensation and sticking of the filter bag surface, thereby further improving the adhesion of particulate matter on the surface of the filter bag, and keeping the filtration efficiency of the filter bag relatively stable. On the basis of the combination of rotating centrifugal loosening of surface attached particles and internal vibration, the filter bag further scrapes its contact surface with the particles, thereby improving the separation and treatment effect of the filter bag on flue gas particles.

[0021] 7. The central column can scrape the inner wall of the processing chamber by driving the pressure plate to move up and down to reduce the attachments on its surface, and the pressure plate that reciprocates up and down can regularly redistribute the rotating uniform airflow of the filter bag in its internal active opening, so that the pressure plate that moves up and down will produce vertical disturbances, making the smoke distribution above and below the filter bag more even, so that the vertical disturbance of the pressure plate and the rotational disturbance of the filter bag through the raised part further improve the uniform distribution of the airflow inside the processing chamber.

[0022] 8. The cross plate 3 is separated from the inside of the raised part by the baffle plate at the top thereof, and an exhaust space exists between the baffle plate and the filter bag, so that the baffle plate blocks and guides the air passing through the filter bag, thereby increasing the airflow rate of the filter bag rotating and stirring under the internal support and blocking of the baffle plate, thereby further improving the degree of uniform airflow of the filter bag rotating and stirring under the internal support and blocking of the baffle plate.

[0023] 9. Replace the cross plate 2 with a pressure plate, so that when the center column drives the pressure plate to move downward, the rotating drive member drives the driven member and the filter bag to reduce or stop the rotation speed, and the pressure plate drives the flue gas particles at its bottom to move downward toward the collecting chamber through the filter layer on its surface, so that the flue gas particles at the bottom of the pressure plate are more easily deposited inside the collecting chamber under its push, and the pressure plate is regularly pressed down to promote cleaning, so that the particulate matter in the airflow inside the processing chamber will not excessively accumulate, and the content of flue gas particles contacted by the filter bag will remain relatively stable for a certain period of time, and the downward movement of the pressure plate will also drive the scraper plate and the inner concave block inside it to move downward through the movable port, so that the scraper plate and the inner concave block clean the surface of the filter bag, so that the particle attachments scraped off by the scraper plate will be partially pushed and precipitated by the downward movement of the pressure plate, reducing the secondary dust after the surface of the filter bag is cleaned, and the filtering and separation effect of the filter bag is improved after the pressure plate is moved down for cleaning.

[0036] Operation process: Preparation before treatment: by connecting the air inlet pipe 1021 to the flue of the steelmaking furnace, the exhaust component 1023 extracts the gas inside the collection chamber 101, the processing chamber 102 and the discharge chamber 103 when it is started, so that the air inside the flue enters the bottom of the processing chamber 102 through the air inlet pipe 1021, and then is processed and separated by the filter bag 203, and then is transported to the subsequent purification step through the exhaust pipe 1022 and the exhaust component 1023; The filter bag 203 is sleeved on the surface of the inner pillar 207 and the cross plate 2071, and the filter bag 203 between the adjacent inner pillars 207 is pushed inward by the inner insertion rod 205 of a group of insertion rods 205 to form a recessed portion 2032, and the two adjacent inner insertion rods 205 will push and pull the filter bag 203 to be recessed inward to form a recessed portion 2032, so that the inner pillar 207 in the middle of the adjacent recessed portions 2032 is lifted up to form a raised portion 2031. After the recessed portion 2032 and the raised portion 2031 are formed, the top of the insertion 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 portion 2033 passes through the through cavity 2073 and is clamped into the flange cavity 2 074, insert the gasket 2023 between the pressing plate 2024 and the collar plate 2072, and then insert the filter bag 203 clamped by the inner pillar 207 and the insertion rod 205 into the interior of the installation opening 10241 and pass through the scraper plate 204 and the inner concave block 2042. After the filter bag 203 is inserted into the interior of the installation opening 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 between the pressing plate 2024 and the driven member 202 by the pressing plate 2024, and then when the driven member 202 rotates, the inner pillar 207 and the insertion rod 205 at the bottom of the collar plate 2072 and the installation block 2075 can be driven to rotate accordingly through the connection between the connecting column 2021 and the pressing plate 2024; After the filter bag 203 passes through the installation opening 10241, the scraper plate 204 and the inner concave block 2042, and the pressure 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 scraper plate 204 and the inner concave block 2042 are arranged on the outside of the filter bag 203, and the inner cross plate 206 is arranged inside the filter bag 203. The center column 1033 and the outer connecting column 1034 are installed with the cross plate 1032, so that the output shaft of the reciprocating propulsion source 1031 and the cross plate 1032 are plugged in, and then the opened discharge chamber 103 is snap-fitted and closed to the top of the processing chamber 102.

[0037] Formal treatment: By starting the suction member 1023, the suction member 1023 continuously draws the gas inside the flue into the processing chamber 102. After the gas enters the processing chamber 102, the rotary drive member 1026 is started, so that the rotary drive member 1026 drives the active member 201 to rotate through the transmission gear 10261 at the bottom thereof, so that the active member 201 drives the driven member 202 to rotate during the rotation, so that during the rotation of the driven member 202, the connection between the connecting column 2021, the pressure plate 2024, the collar plate 2072 and the mounting block 2075 drives the insertion rod 205 and the inner support 207 to rotate with the driven member 202, so that the The filter bag 203 also rotates accordingly, and during the rotation of the filter bag 203, the raised portion 2031 on the side thereof stirs the air inside the processing chamber 102, so that the gas inside the processing chamber 102 is more evenly distributed under the stirring of the filter bag 203 by the raised portion 2031, thereby reducing the installation position of the air inlet pipe 1021, resulting in different filtering and separation loads of the filter bag 203 at different positions, thereby causing wear and filtering efficiency problems. In order to make the filter bag 203 clamped between the insertion rod 205 and the inner support 207 more compact after the raised portion 2031 and the recessed portion 2032 are formed, the inner diameter of the filter bag 203 is matched with the diameter of the cross plate 2071; Through the inner and outer clamping design of the inner support 207 and the insertion rod 205, the surface of the filter bag 203 forms inner and outer recessed parts 2032 and raised parts 2031, thereby increasing the contact area between the surface of the filter bag 203 and the airflow inside the processing chamber 102, and the side of the raised part 2031 will continuously hit the smoke and dust inside the processing chamber 102 when the raised part 2031 rotates with the filter bag 203, thereby improving the filtering efficiency of the filter bag 203, and the protrusion of the raised part 2031 will increase the degree of agitation of the filter bag 203 in contact with the air when the filter bag 203 is rotating and centrifuged, so that the particles inside the smoke are not easy to adhere to the surface of the filter bag 203; In the process of the filter bag 203 rotating to form a uniform airflow, the reciprocating driving source 1031 is started at a fixed time, so that the output shaft of the reciprocating driving source 1031 pushes the cross plate 1032, the center column 1033 and the outer connecting column 1034 to move downward, and in the process of the output shaft of the reciprocating driving source 1031 pushing downward, the rotating driving member 1026 drives the driven member 202 and the filter bag 203 to reduce or stop the rotation speed, so as to facilitate the precipitation of particles in the airflow inside the processing chamber 102; During the downward movement of the outer connecting column 1034, the inner cross plate 206 at its bottom will approach the cross plate three 2071 along the inner support 207 and finally hit the surface of the cross plate three 2071, so that the cross plate three 2071 drives the inner support 207 and the filter bag 203 outside the inner support 207 to vibrate, thereby causing the filter bag 203 to be subjected to internal vibration as a whole. In the process of the filter bag 203 rotating and centrifuging and the raised portion 2031 guiding the air to agitate and hit its side, the particles attached to the surface of the filter bag 203 will be loosened. Combined with the impact vibration generated by the inner cross plate 206 hitting the cross plate three 2071, the loosened particles will be loosened and fall into the collection chamber 101 for sedimentation and collection. Therefore, under the combined effect of the rotating centrifugal loosening of the particles attached to the surface of the filter bag 203 and the internal vibration, the particles attached to the overall surface of the filter bag 203 are further reduced. like Figure 6-7 , and the downward movement of the central column 1033 will drive the linkage ring 10332 and the scraper plate 204 inside the linkage ring 10332 to move downward synchronously through the cross plate 10331. In this process, the rotating driving member 1026 drives the rotation speed of the driven member 202 and the filter bag 203 to decrease or stop, so that the scraper plate 204 moves downward along the insertion rod 205 through the scraper plate 204 and the inner concave block 2042, so that the scraper plate 204 and the inner concave block 2042 scrape the outer surface of the filter bag 203, thereby reducing the condensation and sticking of the filter bag 203 surface, thereby further improving the adhesion of particulate matter on the surface of the filter bag 203, making the filtration efficiency of the filter bag 203 remain relatively stable, and making the filter bag 203 further scrape its contact surface with the particulate matter on the basis of the combination of rotating centrifugal loosening of surface attached particles and internal vibration, thereby improving the separation and treatment effect of the filter bag 203 on the flue gas particulate matter.

[0038] The central column 1033 can scrape the inner wall of the processing chamber 102 to reduce the attachments on its surface by driving the pressure plate 10333 to move up and down, and the pressure plate 10333 that reciprocates up and down can regularly redistribute the rotating uniform airflow of the filter bag 203 in its internal movable opening 10334, so that the pressure plate 10333 that moves up and down will produce vertical disturbances, making the smoke distribution above and below the filter bag 203 more uniform, so that the vertical disturbance of the pressure plate 10333 and the rotational disturbance of the filter bag 203 through the protrusion 2031 further improve the uniform distribution of the airflow inside the processing chamber 102.

[0039] Example 3: This implementation refers to Figure 2-19 As shown, this embodiment is different from the above embodiment in that: Specifically, Figure 8 Shown and Fig.19As shown, a pressure plate 10333 is fixedly connected to the bottom of the central column 1033, and the outer side of the pressure plate 10333 is slidably connected to the inner wall of the processing chamber 102. A movable opening 10334 is arranged on the surface of the pressure plate 10333, and the movable opening 10334 is movably connected through a slot 20421 and an inner concave block 2042. A plurality of filter layers are evenly distributed on the surface of the pressure plate 10333. The material of the filter layer is the same as that of the filter bag 203, both of which are filter cloth bags made of polyphenylene sulfide or polytetrafluoroethylene, and the filter layer does not overlap with the movable opening 10334 and does not contact with the inner wall of the processing chamber 102. A blocking plate 2076 is installed on the top of the cross plate 2071 , and a sliding groove 2062 is extended inwardly from the opening groove 2061 , and the sliding groove 2062 is slidably connected to the blocking plate 2076 .

[0040] The rest of the structures are the same as those of the first and second embodiments.

[0041] Operation process: As an improvement to the rotation of the filter bag 203, Fig.19 As shown, the cross plate 2071 separates the interior of the raised portion 2031 through the baffle plate 2076 on the top thereof, and an exhaust space exists between the baffle plate 2076 and the filter bag 203, so that the baffle plate 2076 blocks and guides the air passing through the filter bag 203, thereby increasing the amount of airflow that is rotated and stirred by the filter bag 203 under the internal support and blocking of the baffle plate 2076, thereby further improving the degree to which the filter bag 203 rotates and stirs the uniform airflow under the internal support and blocking of the baffle plate 2076.

[0042] like Figure 8As shown, the cross plate 10331 is replaced with the pressure plate 10333, so that when the center column 1033 drives the pressure plate 10333 to move downward, the rotating driving member 1026 drives the driven member 202 and the filter bag 203 to reduce or stop the rotation speed, and the pressure plate 10333 drives the flue gas particles at the bottom to move downward toward the collection chamber 101 through the filter layer on its surface, so that the flue gas particles at the bottom of the pressure plate 10333 are more easily deposited in the collection chamber 101 under its push, and the pressure plate 10333 is regularly pressed down to push and clean, so that the particles in the airflow inside the processing chamber 102 will not be Excessive aggregation makes the content of flue gas particles that the filter bag 203 contacts remain relatively stable for a certain period of time, and the downward movement of the pressure plate 10333 will also drive the scraper plate 204 and the inner concave block 2042 inside it to move downward through the movable opening 10334, so that the scraper plate 204 and the inner concave block 2042 clean the surface of the filter bag 203, so that the particle attachments scraped off by the scraper plate 204 will be partially pushed downward by the downward pressure plate 10333, thereby reducing the secondary dust after the surface of the filter bag 203 is cleaned, and the filtering and separation effect of the filter bag 203 is improved after the pressure plate 10333 moves downward to clean it.

[0043] In summary, the inner and outer clamping design of the inner support 207 and the insert rod 205 allows the filter bag 203 to form a raised portion 2031 that rotates and stirs the airflow distribution inside the processing chamber 102. The raised portion 2031 increases the airflow contact area while stirring the airflow, so that the airflow particles are evenly distributed inside the processing chamber 102 by the rotating filter bag 203. During the rotation of the filter bag 203, its own rotating centrifugal force will loosen some of the particles on its surface. Combined with the impact vibration of the inner cross plate 206 inside the filter bag 203 and the scraping plate 204 and the inner concave block 204 on the surface of the filter bag 203, the filter bag 203 is smooth and stable. The up and down scraping of 042 makes it difficult for particulate matter to adhere to the surface of the filter bag 203, and the pressure plate 10333 that is arranged on the outer side of the filter bag 203 and moves up and down, during its up and down movement, pulls the scraper plate 204 and the inner concave block 2042 to scrape and clean the surface of the filter bag 203, while the particulate matter scraped by the filter bag 203 is pushed down and precipitated by the pressure plate 10333, thereby reducing the secondary dust attachment after the attachment on the surface of the filter bag 203 is scraped off, and the up and down movement of the pressure plate 10333 will vertically disturb the airflow of the filter bag 203 rotated and disturbed by the raised portion 2031, so that the airflow distribution is more uniform.
