Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel casting fume treatment, in particular to a stainless steel casting dust removal and desulfurization equipment. Background Art

[0002] At present, a large amount of sulfur-containing flue gas is generated during the stainless steel casting process. In order to avoid environmental pollution caused by direct emission of sulfur-containing flue gas, the sulfur-containing flue gas needs to be desulfurized before it is discharged.

[0003] In the prior art, the desulfurization treatment of sulfur-containing flue gas from stainless steel casting is mostly to allow the flue gas to float up along the inside of the desulfurization tower. When the flue gas floats up, it passes through a partition net carrying a desulfurizer, and the flue gas is desulfurized by the desulfurizer on the partition net. However, as the desulfurizer continues to desulfurize the flue gas, the desulfurizer will become saturated. At this time, it is necessary to clean the saturated desulfurizer on the partition net and replace it with a new desulfurizer. The existing cleaning methods for the saturated desulfurizer mostly rely on manual climbing to the inside of the desulfurization tower, and then manually cleaning the saturated desulfurizer on the partition net. This cleaning method is relatively traditional, and not only requires a lot of manpower labor, but also the cleaning process takes a lot of time, which in turn affects the desulfurization efficiency of the subsequent flue gas.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] See also Figure 1 as well as Figure 2The present embodiment provides a stainless steel casting dust removal and desulfurization equipment, including a cylinder 10, a material shifting assembly 20, a mesh holding assembly 30, a discharge channel 40 and a first drive assembly 50. The lower part of the side wall of the cylinder 10 is provided with an air inlet pipe 102, the side wall of the cylinder 10 is provided with a discharge port 101, the top wall of the cylinder 10 is provided with an exhaust pipe 103, the mesh holding assembly 30 is arranged inside the cylinder 10 for providing support for the desulfurizer, the material shifting assembly 20 is arranged on the mesh holding assembly 30, the discharge channel 40 and the first drive assembly 50, the ... discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive assembly 50, the discharge channel 40 and the first drive The discharging channel 40 is arranged at the bottom of the mesh containing component 30, and one end of the discharging channel 40 is communicated with the discharging port 101. The first driving component 50 is arranged on the top of the cylinder 10, and is used to drive the material shifting component 20 to rotate forward and reverse. When the material shifting component 20 rotates forward, the desulfurizer on the upper part of the mesh containing component 30 can be shifted, and when the material shifting component 20 rotates reversely, the desulfurizer on the upper part of the mesh containing component 30 can be scraped toward the discharging channel 40.

[0037] When it is necessary to desulfurize the flue gas generated during the stainless steel casting process, the flue gas can be introduced into the bottom of the inner side of the cylinder 10 from the air inlet pipe 102. After the flue gas enters the cylinder 10, it floats up and passes through the mesh storage component 30 from bottom to top. After the flue gas passes through the mesh storage component 30, it acts on the desulfurizer, and the desulfurizer is used to remove sulfur oxides in the flue gas. Then the flue gas is discharged from the exhaust pipe 103, thereby realizing the desulfurization of the flue gas. In the above process, the first driving component 50 drives the material shifting component 20 in the mesh storage component 30. The upper part of the release component 30 rotates forward, and then the desulfurizer on the upper part of the mesh containing component 30 is moved, so as to improve the contact effect between the flue gas and the desulfurizer, and improve the desulfurization effect of the flue gas; when the desulfurizer on the upper part of the mesh containing component 30 reaches saturation, the first driving component 50 drives the material shifting component 20 to rotate in the opposite direction, and then the saturated desulfurizer is scraped to the discharge channel 40, and the saturated desulfurizer is discharged to the discharge port 101 through the discharge channel 40, and then discharged to the outside of the cylinder 10 from the discharge port 101, thereby realizing the automatic discharge of the saturated desulfurizer.

[0038] Please refer to the figure Figure 2 In one embodiment, the mesh containing assembly 30 includes an outer ring plate 301, a center plate 302, a containing net 303 and a connecting plate 304. The outer ring plate 301 is fixedly arranged on the inner wall of the cylinder 10, and the center plate 302 is located at the inner center of the outer ring plate 301. The connecting plates 304 and the containing net 303 are each provided with a plurality of groups. A plurality of the connecting plates 304 and a plurality of the containing nets 303 are arranged between the outer ring plate 301 and the center plate 302, and a plurality of the connecting plates 304 and a plurality of the containing nets 303 are alternately distributed.

[0039] The desulfurizer is supported by a plurality of containing nets 303. When the flue gas floats up along the inside of the cylinder 10, the flue gas can pass through the containing nets 303 from bottom to top and then act on the desulfurizer on the top of the containing nets 303. The desulfurizer is used to remove sulfur oxides in the flue gas, thereby achieving desulfurization of the flue gas.

[0040] See also Figure 1 as well as Figure 2 In one embodiment, the first driving component 50 includes a rotating shaft 501 and a motor 503, and the motor 503 is fixedly installed on the upper part of the cylinder 10. One end of the rotating shaft 501 is connected to the output end of the motor 503, and the other end extends to the inside of the cylinder 10. The material shifting component 20 includes a shifting rod 201 and a scraper 202. The scraper 202 is distributed radially along the cylinder 10, and one end of the scraper 202 is connected to the rotating shaft 501. The shifting rod 201 is provided with a plurality of groups, and a plurality of the shifting rods 201 are installed at the bottom of the scraper 202 and are spaced in sequence along the length direction of the scraper 202. The lower ends of the plurality of the shifting rods 201 are in contact with the upper surface of the containing net 303.

[0041] The motor 503 drives the rotating shaft 501 to rotate forward, thereby driving the scraper 202 and the plurality of levers 201 to rotate forward. When the plurality of levers 201 rotate forward, the desulfurizer on the upper part of the containing net 303 is moved, so that the flue gas passing through the containing net 303 from bottom to top can be more fully in contact with the desulfurizer, thereby improving the desulfurization effect of the flue gas.

[0042] See also Figure 2 , Figure 3 as well as Figure 4In one embodiment, a plurality of insertion holes 205 are provided at the bottom of the scraper 202, and the plurality of insertion holes 205 correspond to the plurality of levers 201 one by one. The upper end of each group of levers 201 is inserted into the corresponding insertion holes 205, and a group of first springs 206 for providing elastic support to the levers 201 are provided inside each group of insertion holes 205. A sleeve 204 is fixedly provided at one end of the scraper 201, and the sleeve 204 is sleeved on the outside of the rotating shaft 501. A key groove (not shown in the figure) is provided on the inner wall of the sleeve 204. A key 502 matching the key groove is fixedly provided on the outer wall of the rotating shaft 501. A material discharge port 305 is provided, and the material discharge channel 40 is fixedly arranged at the bottom of the connecting plate 304 and communicated with the material discharge port 305. A sealing plate 306 is hingedly arranged on the upper part of the connecting plate 304, and one side of the sealing plate 306 is connected to the connecting plate 304 through a spring piece 307. A second driving component 60 is also provided on the inner wall of the cylinder 10. When the rotating shaft 501 rotates in the reverse direction and then drives the sleeve 204, the scraper 202 and a plurality of levers 201 to rotate in the reverse direction through the cooperation of the key 502 and the key slot, the second driving component 60 is used to drive the scraper 202 to move downward, so that the scraper 202 is in contact with the upper surface of the containing net 303.

[0043] When the rotating shaft 501 rotates forward, the key 502 and the key slot can be used to cooperate to drive the sleeve 204, the scraper 202 and the plurality of levers 201 to rotate forward synchronously. The plurality of levers 201 can move the desulfurizer on the upper part of the containing net 303. When the plurality of levers 201 slide from the upper surface of a group of containing nets 303 to the upper surface of a group of connecting plates 304, the lever 201 can push the sealing plate 306 so that the sealing plate 306 rotates relative to the connecting plate 304 and covers the upper part of the blanking port 305 to seal the blanking port 305 and prevent the lever 201 from carrying a small amount of desulfurizer from the blanking port 305 into the discharge channel 40. When the lever 201 passes over the upper part of the sealing plate 306, the spring piece 307 pulls the sealing plate 306 to rotate in the opposite direction, thereby causing the sealing plate 306 to be in an inclined state. As the desulfurizer on the upper part of the containing net 303 is placed on the surface of the containing net 303 for a long time, the sealing plate 306 is pushed to rotate relative to the connecting plate 304 and covers the upper part of the blanking port 305. The sulphur oxides in the flue gas are absorbed. When the desulfurizer on the upper part of the holding net 303 is saturated, the motor 503 drives the rotating shaft 501 to rotate in the opposite direction, and then drives the sleeve 204, the scraper 202 and the plurality of levers 201 to rotate in the opposite direction through the cooperation of the key 502 and the key slot. At this time, the second driving assembly 60 drives the scraper 202 to move downward, and the sleeve 204 adaptively slides down along the outer side of the rotating shaft 501. When the scraper 202 moves downward, the plurality of levers 201 are forced to move toward the inside of the corresponding socket 205 until the bottom of the scraper 202 contacts the upper surface of the holding net 303. As the scraper 202 rotates in the opposite direction, the scraper 202 scrapes the saturated desulfurizer on the upper part of the holding net 303 to the upper part of the connecting plate 304, and then falls into the discharge channel 40 from the drop port 305, and finally is discharged to the outside of the cylinder 10 through the discharge port 101, thereby realizing the automatic discharge of the saturated desulfurizer.

[0044] See also Figure 2 as well as Figure 3 In one embodiment, the second driving assembly 60 includes a driving ring plate 601, a first limit block 602 and a second limit block 604. The driving ring plate 601 is fixedly mounted on the inner wall of the cylinder 10. A plurality of spaced inclined grooves 603 are provided on the inner side of the driving ring plate 601. A group of the first limit blocks 602 are hingedly provided on one side of the upper part of each group of the inclined grooves 603. A group of the second limit blocks 604 are hingedly provided on one side of the lower part of each group of the inclined grooves 603. One side of each group of the first limit blocks 602 and each group of the second limit blocks 604 are connected to the driving ring plate 601 through a group of second springs (not shown in the figure). The first limit block 602, the second limit block 604 and the inclined groove 603 have the same inclination direction. An L-shaped slide bar 203 is fixedly provided on the upper part of the scraper 202. One end of the L-shaped slide bar 203 away from the scraper 202 is overlapped on the upper part of the driving ring plate 601.

[0045] When the rotating shaft 501 rotates forward and drives the scraper 202 and the plurality of levers 201 to rotate forward to move the desulfurizer on the upper part of the holding net 303, the scraper 202 drives the L-shaped slide bar 203 to slide along the upper part of the driving ring plate 601. When the L-shaped slide bar 203 is about to slide to the upper position of a certain inclined groove 603, the L-shaped slide bar 203 can push the corresponding first limit block 602 and drive the first limit block 602 to rotate toward the upper direction of the corresponding inclined groove 603. When the first limit block 602 rotates, it can block the upper end of the inclined groove 603, so that the L-shaped slide bar 203 can smoothly pass the current inclined groove 603 and continue to slide along the upper part of the driving ring plate 601. The scraper 202 slides to ensure that the scraper 202 is always away from the holding net 303; when the desulfurizer on the upper part of the holding net 303 is saturated, the rotating shaft 501 rotates in the opposite direction, thereby driving the scraper 202 to rotate in the opposite direction. When the scraper 202 rotates in the opposite direction, it drives the L-shaped slide bar 203 to slide in the opposite direction along the upper part of the driving ring plate 601. At this time, the L-shaped slide bar 203 can slide to the upper part of a group of inclined grooves 603 and then slide from the inside of the inclined grooves 603 into the lower part of the driving ring plate 601. At this time, the scraper 202 moves downward and drives the sleeve 204 to slide down along the outside of the rotating shaft 501. The bottom of the scraper 202 contacts the upper surface of the holding net 303. As the rotating shaft 501 continues to rotate in the opposite direction, the scraper 202 fits the upper surface of the holding net 303. The surface rotates in the opposite direction to scrape the saturated desulfurizer on the upper part of the holding net 303 toward the upper part of the connecting plate 304, so that the saturated desulfurizer falls into the discharge channel 40 through the drop port 305 and is discharged from the discharge port 101; when the scraper 202 is attached to the upper part of the holding net 303 and rotates in the opposite direction, the L-shaped slide bar 203 slides in the opposite direction along the lower part of the driving ring plate 601, and the L-shaped slide bar 203 pushes a plurality of second limit blocks 604 in turn so that the plurality of second limit blocks 604 are deflected in the direction of the driving ring plate 601 in turn; when the saturated desulfurizer is discharged to the outside of the cylinder 10 through the discharge channel 40 and the discharge port 101, the motor 503 drives the rotating shaft 501 to rotate forward again, thereby driving the scraper 202 rotates forward, and the scraper 202 drives the L-shaped slide bar 203 to slide forward along the lower part of the driving ring plate 601. The L-shaped slide bar 203 acts on a group of second limit blocks 604 and is then introduced into the inclined groove 603 by the second limit blocks 604. The L-shaped slide bar 203 slides up along the inclined groove 603 to the upper part of the driving ring plate 601, thereby driving the scraper 202 to move upward. Under the support of the first spring 206, a plurality of levers 201 automatically extend to the outside of the corresponding socket 205 and keep in contact with the upper surface of the containing net 303, so that as the scraper 202 rotates forward, a plurality of levers 201 can continue to move the desulfurizer refilled on the upper surface of the containing net 303.

[0046] See also Figure 1 In one embodiment, a feed pipe 104 is further provided on the upper portion of the cylinder 10 , and a valve is provided inside the feed pipe 104 .

[0047] When the flue gas passes through the containing net 303 from bottom to top and is then desulfurized by the desulfurizer on the upper part of the containing net 303, the valve in the feed pipe 104 is in a closed state, so that the desulfurized flue gas can be discharged smoothly through the exhaust pipe 103; when the scraper 202 rotates in the opposite direction to scrape the saturated desulfurizer on the upper part of the containing net 303 into the discharge channel 40 through the discharge port 305, and the saturated desulfurizer is discharged to the outside of the cylinder 10 through the discharge port 101, the staff can open the valve in the feed pipe 104, and then reload the external desulfurizer into the upper part of the containing net 303 through the feed pipe 104.

[0048] In one embodiment, the discharge channel 40 is inclined. When the saturated desulfurizer falls into the discharge channel 40 through the discharge port 305 , the saturated desulfurizer can automatically slide down along the inclined discharge channel 40 and then be automatically discharged from the discharge port 101 to the outside of the cylinder 10 .

[0049] In one embodiment, when the smoke rises along the inside of the cylinder 10 and passes through the containing net 303 from bottom to top, the dust and debris in the smoke can also be blocked at the bottom of the containing net 303, thereby achieving the purpose of smoke dust removal.

[0050] In order to ensure that the flue gas can better pass through the containing net 303 after entering the cylinder 10, in one embodiment, an induced draft fan can also be arranged in the air inlet pipe 104, and the flue gas generated during the stainless steel casting process is sucked to the lower inner part of the cylinder 10 by the induced draft fan, so that the flue gas entering the lower inner part of the cylinder 10 has a certain flow speed and pressure, thereby ensuring that the flue gas can smoothly pass through the containing net 303 and the desulfurizer on the upper part of the containing net 303 from bottom to top, thereby improving the desulfurization effect of the flue gas.

[0051] In the embodiment of the present invention, when it is necessary to desulfurize the flue gas generated in the stainless steel casting process, the flue gas can be introduced into the bottom of the inner side of the cylinder 10 from the air inlet pipe 102. After entering the cylinder 10, the flue gas floats up, thereby passing through the mesh holding component 30 from bottom to top. After the flue gas passes through the mesh storage component 30, it acts on the desulfurizer, and the sulfur oxides in the flue gas are removed by the desulfurizer. Then the flue gas is discharged from the exhaust pipe 103, thereby realizing the desulfurization of the flue gas. In the above process, the first driving component 50 drives the material shifting component 20 to rotate forward on the upper part of the mesh holding component 30, thereby desulfurizing the upper part of the mesh holding component 30. The desulfurizer is moved, thereby improving the contact effect between the flue gas and the desulfurizer, and improving the desulfurization effect of the flue gas; when the desulfurizer on the upper part of the mesh containing component 30 is saturated, the first driving component 50 drives the material shifting component 20 to rotate in the opposite direction, and then scrapes the saturated desulfurizer to the discharge channel 40, and the saturated desulfurizer is discharged to the discharge port 101 through the discharge channel 40, and then discharged to the outside of the cylinder 10 from the discharge port 101, thereby realizing the automatic discharge of the saturated desulfurizer. Compared with the prior art, it can realize the automatic desulfurization treatment of stainless steel casting flue gas, and can also automatically clean and discharge the saturated desulfurizer, thereby improving the desulfurization efficiency of the flue gas.

[0052] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
