Description

Technical Field

[0001] The invention relates to the technical field of unloading devices, and in particular to an anti-blocking roller type unloading device. Background Art

[0002] SO2 and NO in steel production enterprises X The emission mainly comes from the sintering and coking process. Activated carbon desulfurization and denitrification technology is the most widely used flue gas desulfurization and denitrification process. This technology uses the adsorption and catalytic properties of activated carbon to make SO2, O2 and water vapor in the flue gas adsorbed on the surface of activated coke respectively, and then react to generate H2SO4 which is adsorbed in the micropores of activated coke, thereby achieving the desulfurization effect. The flue gas leaving the desulfurization bed is mixed with ammonia in the mixing section and then enters the denitrification bed. Under the catalytic action of activated carbon, NO X Reacts with NH3 to produce nitrogen and water.

[0003] The activated carbon flue gas purification system includes a discharge device for transferring and conveying materials. Figure 1 and Figure 2 As shown, the unloading device includes an activated carbon unloading bin 100 and a round roller 200. The round roller 200 can rotate around its own axis. The activated carbon unloading bin 100 is located above the round roller 200. A part of its bottom end is in sliding contact with the round roller 200, and a gap is maintained between the other part and the round roller 200 to form a unloading port 300 between the round roller 200. When the round roller 200 rotates counterclockwise, the activated carbon in the activated carbon unloading bin 100 is brought out through the unloading port 300 to achieve unloading.

[0004] The above scheme has the following defects: since the sintering flue gas contains a large amount of chloride ions, and the activated carbon after desulfurization adsorbs sulfuric acid, these two substances can easily react with ammonia to form block crystals. The block crystals are large in volume and can easily block the discharge port 300. After the blockage, the discharge device no longer discharges material, resulting in hot spots in the bed layer, affecting the normal operation of the flue gas purification system, causing the sintering machine to be forced to shut down, the desulfurization and denitrification process to be terminated, and the normal production process to be delayed.

[0005] Therefore, there is an urgent need for an anti-blocking roller unloading device to solve the above-mentioned problems existing in the prior art. Summary of the invention

[0006] The purpose of the present invention is to provide an anti-blocking roller type unloading device, which can prevent blockage from occurring during the unloading process, ensure normal discharge of materials, and reduce the production termination phenomenon caused by blockage.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0008] Provided is a material blocking prevention roller type unloading device, comprising:

[0009] Body;

[0010] A silo is disposed in the body, and a discharge port is provided at the lower end of the silo;

[0011] The unloading roller comprises a rotating roller body and a plurality of material-crushing convex portions distributed at intervals along the circumference of the rotating roller body, wherein the rotating roller body is rotatably arranged in the body around its own central axis, and a material receiving groove is formed between two adjacent material-crushing convex portions; and the outer surface of the material-crushing convex portion facing away from the rotating roller body is a contact surface;

[0012] The edge of the discharge port is in sliding contact with the contact surface, and the material in the silo falls into the receiving trough through the discharge port. At least part of the crushed material protrusion can enter the silo through the discharge port to extrude the material together with the inner wall of the silo.

[0013] In the above technical solution, when the rotating roller body driving the discharge roller rotates around its own central axis, the edge of the discharge port of the silo can slide in contact with the outer surface of the crushing convex part of the discharge roller away from the rotating roller body, and the material in the silo falls into the receiving trough through the discharge port at its lower end. As the discharge roller rotates, the material in the silo is taken out through the receiving trough to realize the discharge of the material in the silo. When there is a large block material in the silo, and the block material falls to the vicinity of the discharge port, the crushing convex part can enter the silo through the discharge port. As the crushing convex part rotates, it and the inner wall of the silo squeeze the block material to crush it. The crushed material falls into the receiving trough for smooth discharge, preventing the large block material from blocking the discharge port of the silo, realizing the continuity of discharge, and reducing the production termination phenomenon caused by blockage. When the unloading device is used in a flue gas purification system, the material stored in the silo is activated carbon. When the activated carbon generates large block crystals, the unloading roller of the unloading device can smoothly crush the crystals at the discharge port to avoid blockage caused by the crystals. During the rotation of the unloading roller, the activated carbon can be continuously discharged to ensure the long-term stable operation of the flue gas purification system, effectively solve the problem of frequent shutdown of the flue gas purification system due to blockage, and reduce the labor intensity of workers.

[0014] As an optional solution of the anti-blocking roller type unloading device provided by the present invention, the two ends of the crushing convex part along the rotation direction thereof are respectively provided with a first arc-shaped concave surface and an arc-shaped convex surface, and the first arc-shaped concave surface and the arc-shaped convex surface are connected by the contact surface;

[0015] The connection between the first arc-shaped concave surface and the contact surface forms a crushing blade for squeezing the material.

[0016] In the above technical solution, the sharpness of the crushing convex part can be increased by forming a crushing blade, so that the material can be shredded more smoothly. Moreover, among two adjacent crushing convex parts, a receiving groove is formed between the first arc-shaped concave surface of one, the arc-shaped convex surface of the other, and the outer wall surface of the rotating roller body. The internal space of the formed receiving groove is expanded, which can increase the discharge amount of activated carbon and speed up the discharge speed. In addition, when the crushing convex part rotates to enter the silo, the first arc-shaped concave surface tends to be upward, which can better receive the activated carbon leaking from the right end and eliminate the leakage phenomenon.

[0017] As an optional solution of the anti-blocking roller unloading device provided by the present invention, at least one first crushing spike is convexly provided on one end surface of the crushing convex portion along its rotation direction, and the first crushing spike is used to contact with the material to squeeze and crush the material.

[0018] In the above technical solution, the first crushing spikes can reduce the difficulty of crushing, speed up the crushing speed, and ensure the smoothness of the activated carbon feeding.

[0019] As an optional solution of the anti-blocking roller unloading device provided by the present invention, one end surface of the crushing convex portion along its rotation direction includes a crushing surface and a second arc-shaped concave surface, the second arc-shaped concave surface is connected to the contact surface through the crushing surface, and the second arc-shaped concave surface is concave relative to the crushing surface;

[0020] The first crushing material spikes are convexly arranged on the crushing surface.

[0021] As an optional solution of the anti-blocking roller type unloading device provided by the present invention, the first material-crushing spikes extend along the axial direction of the rotating roller body;

[0022] Alternatively, the first material-crushing spikes are conical and are arranged in at least one row, and a plurality of the first material-crushing spikes in each row are distributed at intervals along the axial direction of the rotating roller body.

[0023] As an optional solution of the anti-blocking roller type unloading device provided by the present invention, the silo includes an extrusion plate and a side panel, and the extrusion plate and the side panel are connected end to end to enclose and form an inner cavity of the silo; the extrusion plate is used to extrude the material together with the crushed material protrusion;

[0024] The thickness of the extrusion plate is greater than the thickness of the side panel; or, the silo also includes a protective plate, which is stacked on the inner side of the extrusion plate for contacting the material; or, the anti-blocking roller unloading device also includes a pressure plate, which is fixedly connected to the body and abuts against the outer side wall of the extrusion plate.

[0025] In the above technical solution, by thickening the extrusion plate, stacking a protective plate on the extrusion plate, and setting a pressure plate between the machine body and the outer wall of the extrusion plate, the deformation problem of the extrusion plate can be reduced and the bearing capacity of the extrusion plate can be improved.

[0026] As an optional solution of the anti-blocking roller type unloading device provided by the present invention, a reinforcing rib is connected between the extrusion plate and the side panel.

[0027] In the above technical solution, the connection strength between the extrusion plate and the side panel can be increased by providing reinforcing ribs, thereby preventing cracking between the two due to excessive load.

[0028] As an optional solution of the anti-blocking roller type unloading device provided by the present invention, the inner wall of the silo is protrudingly provided with second material crushing spikes, and the second material crushing spikes are used to contact with the material to squeeze and crush the material.

[0029] In the above technical solution, the crushing effect can be further enhanced by providing the second crushing spikes.

[0030] As an optional solution of the anti-blocking roller type unloading device provided by the present invention, the unloading roller also includes a fastener, and the crushing protrusion and the rotating roller body are detachably connected through the fastener.

[0031] In the above technical solution, when the crushing protrusion fails, it can be replaced in a targeted manner to reduce maintenance costs.

[0032] As an optional solution of the anti-blocking roller type unloading device provided by the present invention, the silo includes an extrusion plate and a side panel, and the extrusion plate and the side panel are connected end to end to enclose and form an inner cavity of the silo; the extrusion plate is used to extrude the material together with the crushed material protrusion;

[0033] The vertical projection of the central axis of the rotating roller body overlaps with the vertical projection of the discharge port, and the vertical distance between the lowest point of the extrusion plate and the central axis of the rotating roller body is L1;

[0034] The contact surface is an arc-shaped surface, the center of the arc where the contact surface is located coincides with the central axis of the rotating roller body, and the radius of the arc where the contact surface is located is L2;

[0035] Among them, L1<L2.

[0036] In the above technical solution, when the crushing protrusion rotates into the silo, its highest point can be higher than the lowest point of the extrusion plate, so that the crushing protrusion and the extrusion plate at least partially overlap in the horizontal direction, and the overlapping part can better squeeze and crush the block crystals.

[0037] Beneficial effects of the present invention:

[0038] The anti-blocking roller type unloading device provided by the present invention can make sliding contact with the outer surface of the discharge port of the silo with the material crushing convex part of the unloading roller away from the rotating roller body when the rotating roller body of the unloading roller is driven to rotate around its own central axis, and the material in the silo falls into the receiving trough through the discharge port at its lower end, and the material in the silo is taken out through the receiving trough as the unloading roller rotates, so as to realize the unloading of the material in the silo. When there is a large block material in the silo, and the block material falls to the vicinity of the discharge port, the material crushing convex part can enter the silo through the discharge port, and as the material crushing convex part rotates, it and the inner wall of the silo squeeze the block material to crush it, and the crushed material falls into the receiving trough to discharge smoothly, so as to prevent the large block material from blocking the discharge port of the silo, realize the continuity of material discharge, and reduce the production termination phenomenon caused by material blockage. When the unloading device is used in a flue gas purification system, the material stored in the silo is activated carbon. When the activated carbon generates large block crystals, the unloading roller of the unloading device can smoothly crush the crystals at the discharge port to avoid blockage caused by the crystals. During the rotation of the unloading roller, the activated carbon can be continuously discharged to ensure the long-term stable operation of the flue gas purification system, effectively solve the problem of frequent shutdown of the flue gas purification system due to blockage, and reduce the labor intensity of workers.

[0062] In the embodiments of the present invention, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0063] like Figure 3 and Figure 4 As shown, this embodiment provides an anti-blocking roller unloading device, which can prevent blockage from occurring during the unloading process, ensure normal discharge of materials, and reduce the production termination phenomenon caused by blockage.

[0064] The anti-blocking roller type unloading device comprises a machine body 1, a silo 2 and a unloading roller 3. The silo 2 is arranged in the machine body 1, and the lower end of the silo 2 has a discharge port; the unloading roller 3 comprises a rotating roller body 31 and a plurality of material crushing protrusions 32 distributed at intervals along the circumference of the rotating roller body 31, the rotating roller body 31 is rotatably arranged in the machine body 1 around its own central axis, and a material receiving groove 33 is formed between two adjacent material crushing protrusions 32; the outer surface of the material crushing protrusion 32 facing away from the rotating roller body 31 is a contact surface 321; the edge of the discharge port is in sliding contact with the contact surface 321, and the material in the silo 2 falls into the material receiving groove 33 through the discharge port, and at least part of the material crushing protrusion 32 can enter the silo 2 through the discharge port to squeeze the material together with the inner wall of the silo 2.

[0065] Optionally, both the upper and lower ends of the silo 2 are open, the opening at the upper end is the feed inlet, and the opening at the lower end is the above-mentioned discharge outlet.

[0066] The anti-blocking roller unloading device provided in the embodiment of the present application refers to Figure 4 When the rotating roller body 31 driving the discharge roller 3 rotates counterclockwise around its own central axis, the edge of the discharge port of the silo 2 can slide in contact with the outer surface of the crushing convex portion 32 of the discharge roller 3 away from the rotating roller body 31, and the material in the silo 2 falls into the receiving groove 33 through the discharge port at its lower end. As the discharge roller 3 rotates, the material in the silo 2 is taken out through the receiving groove 33, thereby realizing the discharge of the material in the silo 2. Figure 4 In the process, materials are discharged on the left side.

[0067] When there is a large block material in the silo 2 and the block material falls near the discharge port, the crushing protrusion 32 can enter the silo 2 through the discharge port. As the crushing protrusion 32 rotates, it and the inner wall of the silo 2 squeeze the block material to crush it. The crushed material falls into the receiving trough 33 for smooth discharge, preventing the large block material from blocking the discharge port of the silo 2, achieving continuous discharge and reducing the production termination phenomenon caused by blockage.

[0068] In this embodiment, taking the activated carbon 1000 as the material in the silo 2 as an example, the activated carbon 1000 is prone to generate block crystals 2000 during the flue gas purification process, and the volume of the block crystals 2000 is much larger than the volume of a single piece of activated carbon 1000.

[0069] When the unloading device is used in a flue gas purification system, the material stored in the silo 2 is activated carbon 1000. When the activated carbon 1000 generates large block crystals 2000, the unloading roller 3 of the unloading device can smoothly crush the crystals at the discharge port to avoid blockage caused by the crystals. During the rotation of the unloading roller 3, the continuous unloading of the activated carbon 1000 can be maintained to ensure the long-term stable operation of the flue gas purification system, effectively solve the problem of frequent shutdown of the flue gas purification system due to blockage, and reduce the labor intensity of workers.

[0070] Exemplarily, at least four material-crushing protrusions 32 are evenly arranged in the circumferential direction of the rotating roller body 31 to avoid material leakage.

[0071] In some embodiments, the crushing convex portion 32 is integrally formed with the rotating roller body 31. For example, on the basis of a cylindrical roller, a plurality of receiving grooves 33 are provided at intervals in the circumferential direction of the cylindrical roller to form the crushing convex portion 32. The manufacturing is simple and the connection strength between the rotating roller body 31 and the crushing convex portion 32 can be ensured. Moreover, the processing can be performed on the basis of the cylindrical roller of the existing unloading device, which can reduce the processing cost and make full use of the existing materials.

[0072] In other embodiments, the discharge roller 3 further includes fasteners, and the crushing protrusion 32 is detachably connected to the rotating roller body 31 through the fasteners. Since the crushing protrusion 32 squeezes and crushes the block crystals 2000 with the inner wall of the silo 2, it may be severely worn after long-term use, and even have pits, cracks at the corners, and other problems. In this case, the faulty crushing protrusion 32 can be replaced in a targeted manner without replacing the entire discharge roller 3.

[0073] Exemplarily, the fastener may be a high-strength long screw.

[0074] In some embodiments, Figure 5 As shown, the first arcuate concave surface 322 and the arcuate convex surface 323 are respectively provided at both ends of the crushing convex portion 32 along the rotation direction thereof, and the first arcuate concave surface 322 and the arcuate convex surface 323 are connected by a contact surface 321. A crushing blade 324 for squeezing materials is formed at the connection between the first arcuate concave surface 322 and the contact surface 321. Specifically, the tangent line of the first arcuate concave surface 322 at the crushing blade 324 and the tangent line of the contact surface 321 at the crushing blade 324 are arranged at an acute angle, and the acute angle is exemplarily between 5 degrees and 60 degrees, such as 45 degrees, 30 degrees, etc. By forming the crushing blade 324, the sharpness of the crushing convex portion 32 can be increased, so that the materials can be crushed more smoothly.

[0075] Moreover, a receiving groove 33 is formed between the first arc-shaped concave surface 322 of one of the two adjacent crushing convex parts 32, the arc-shaped convex surface 323 of the other, and the outer wall surface of the rotating roller body 31. The internal space of the formed receiving groove 33 is enlarged, which can increase the feeding amount of the activated carbon 1000 and speed up the feeding speed. In addition, when the crushing convex part 32 rotates to enter the silo 2, the first arc-shaped concave surface 322 tends to be upward, which can better receive the activated carbon 1000 leaking from the right end and eliminate the leakage phenomenon.

[0076] Further, see Figure 5 The crushing convex part 32 is located at the upper left corner. At this time, the activated carbon 1000 discharged from the discharge port of the silo 2 is discharged along the arc-shaped convex surface 323 of the crushing convex part 32, which can improve the uniformity of the activated carbon 1000 when being discharged.

[0077] In some embodiments, see Figure 6At least one first crushing spike 325 is convexly provided on one end surface of the crushing convex portion 32 along the rotation direction thereof (i.e., the first crushing spike 325 is provided on the end surface for extruding the material), and the first crushing spike 325 is used to contact the material to extrude and crush the material. When the material is activated carbon 1000, and there are block crystals 2000 generated by the activated carbon 1000 at the discharge port of the silo 2, the first crushing spike 325 can reduce the crushing difficulty, speed up the crushing speed, and ensure the smoothness of the activated carbon 1000 when it is discharged.

[0078] In some embodiments, see Figure 6 The end surface of the crushing protrusion 32 for pressing the block crystals 2000 is a plane, and the first crushing spikes 325 can be distributed on the plane.

[0079] In other embodiments, see Figure 7 , one end surface of the crushing convex part 32 along the rotation direction thereof includes a crushing surface 326 and a second arc-shaped concave surface 327, the second arc-shaped concave surface 327 is connected to the contact surface 321 through the crushing surface 326, and the second arc-shaped concave surface 327 is concave relative to the crushing surface 326; a first crushing spike 325 is convexly provided on the crushing surface 326. That is, the end surface of the crushing convex part 32 for squeezing the block crystal 2000 includes the second arc-shaped concave surface 327 and the crushing surface 326 convexly provided with the first crushing spike 325. On the one hand, the setting of the first crushing spikes 325 on the crushing surface 326 can reduce the difficulty of crushing the block crystals 2000, speed up the crushing speed, and further prevent blockage; on the other hand, the setting of the second arc-shaped concave surface 327 can expand the internal space of the receiving trough 33, so that more activated carbon 1000 can be brought out through the receiving trough 33 during the rotation of the unloading roller 3; moreover, the second arc-shaped concave surface 327 is in an upturned state when it is about to enter the silo 2, and can catch the activated carbon 1000 leaking from the right end of the silo 2, thereby avoiding leakage at the right end.

[0080] Furthermore, the above-mentioned arc-shaped convex surface 323 can be provided on the end surface of the crushing convex portion 32 opposite to the crushing surface 326 to play a guiding role when the activated carbon 1000 is discharged.

[0081] In some embodiments, the first material-crushing spikes 325 extend along the axial direction of the rotating roller body 31. That is, along the axial direction of the rotating roller body 31, the first material-crushing spikes 325 are in a long strip shape, ensuring uniform material crushing in the axial direction of the rotating roller body 31.

[0082] In other embodiments, the first crushing spikes 325 are conical and arranged in at least one row, and a plurality of first crushing spikes 325 in each row are spaced apart along the axial direction of the rotating roller body 31. The plurality of conical first crushing spikes 325 not only reduce the crushing difficulty, but also improve the crushing degree, so that the volume of the crushed crystals is smaller and easier to discharge.

[0083] See Figure 6 、 Figure 8 and Fig. 9 , the silo 2 includes an extrusion plate 21 and a side enclosure plate 22. The extrusion plate 21 and the side enclosure plate 22 are connected end to end to enclose and form the inner cavity of the silo 2; the side enclosure plate 22 is exemplarily in a "U" shape to enclose the silo 2 with the extrusion plate 21. After the broken material convex part 32 enters the silo 2 through the discharge port, the broken material convex part 32 first gradually approaches the extrusion plate 21, and the distance between them gradually decreases. When there is a massive crystal 2000 between the two, the broken material convex part 32 and the extrusion plate 21 jointly extrude the massive crystal 2000 to achieve material breaking.

[0084] In some embodiments, as Figure 8 shown, the thickness of the extrusion plate 21 is greater than the thickness of the side enclosure plate 22, so that the extrusion plate 21 has higher strength and anti-deformation ability relative to the side enclosure plate 22, avoiding serious deformation problems of the extrusion plate 21 due to long-term extrusion of the activated carbon 1000.

[0085] In some other embodiments, as Fig. 9 shown, the silo 2 further includes a protection plate 23. The protection plate 23 is stacked on the inner side of the extrusion plate 21 and is used to contact the massive crystal 2000 and jointly extrude and crush the massive crystal 2000 with the broken material convex part 32. By stacking the protection plate 23 on the inner side of the extrusion plate 21, it can be avoided that the extrusion plate 21 directly contacts the massive crystal 2000. The extrusion force during material breaking is transmitted to the extrusion plate 21 through the protection plate 23, making the force received by the extrusion plate 21 more uniform and reducing the phenomenon of local deformation of the extrusion plate 21.

[0086] In some other new embodiments, as Figure 3 shown, the anti-blocking roller type discharging device further includes a bearing plate 4. The bearing plate 4 is fixedly connected to the inside of the machine body 1, and the bearing plate 4 abuts against the outer side wall of the extrusion plate 21, so that the force for extruding the massive crystal 2000 acts on the bearing plate 4 through the extrusion plate 21, and the bearing plate 4 transmits the force to the machine body 1. That is, by setting the bearing plate 4, the extrusion force received by the extrusion plate 21 during material breaking can be shared, reducing the load received by the extrusion plate 21, and thus eliminating the problem of deformation of the extrusion plate 21.

[0087] Exemplarily, the bearing plate 4 includes an L-shaped plate. The short plate of the L-shaped plate is connected to the inner top wall of the machine body 1, and the long plate of the L-shaped plate abuts against the outer side of the extrusion plate 21 to share the force received by the extrusion plate 21. Further, a triangular reinforcing plate can be provided between the long plate and the short plate of the L-shaped plate to prevent breakage between the long plate and the short plate and improve the load-bearing capacity of the entire bearing plate 4.

[0088] See Figure 8A reinforcing rib 24 is connected between the extruded plate 21 and the side panel 22, which can increase the connection strength between the extruded plate 21 and the side panel 22 and prevent cracks, breakages, etc. from occurring at the connection between the two.

[0089] In some embodiments, see Figure 6 The inner wall of the silo 2 is convexly provided with a second crushing spike 25, which is used to contact the block crystals 2000 to squeeze and crush the block crystals 2000, further reducing the crushing difficulty and accelerating the crushing speed.

[0090] like Figure 3 As shown, in this embodiment, the vertical projection of the central axis of the rotating roller body 31 overlaps with the vertical projection of the discharge port, and the vertical distance between the lowest point of the extrusion plate 21 and the central axis of the rotating roller body 31 is L1. The contact surface 321 is an arc surface, and the center of the arc where the contact surface 321 is located coincides with the central axis of the rotating roller body 31, and the radius of the arc where the contact surface 321 is located is L2; ​​wherein, L1<L2. With such a configuration, when the crushing protrusion 32 rotates into the silo 2, its highest point can be higher than the lowest point of the extrusion plate 21, so that the crushing protrusion 32 and the extrusion plate 21 at least partially overlap in the horizontal direction, and the block crystals 2000 can be better squeezed and crushed through the overlapping part.

[0091] Furthermore, in this embodiment, along the rotation direction of the discharge roller 3, the edge of the discharge port extends in an arc shape, and the radius of the arc is the same as the radius of the arc where the contact surface 321 is located. After the silo 2 and the discharge roller 3 are installed, the arc where the edge of the discharge port is located is roughly concentric with the arc where the contact surface 321 is located, ensuring that the discharge roller 3 can slide in contact with the edge of the discharge port during rotation.

[0092] For example, the lowest point of the plate section on the side panel 22 directly facing the extrusion plate 21 is higher than the lowest point of the extrusion plate 21. That is, the lowest point of the extrusion plate 21 is the lowest point of the edge of the discharge port of the entire silo 2, so that when the crushing protrusion 32 enters the silo 2 for crushing, the overlapping area of ​​the crushing protrusion 32 and the extrusion plate 21 in the horizontal direction is larger, which helps to improve the crushing effect.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
