[0001] The invention relates to the technical field of roasting devices, in particular to a gasification filter residue roasting device. Background Art

[0002] In the petrochemical industry, oil residue gasification is an important process device. Oil residue gasification will produce a large amount of gasification filter cake. The gasification filter cake is actually chemical sludge with high water content and contains a certain amount of carbon-containing organic matter and trace amounts of metal elements such as molybdenum, nickel, and vanadium.

[0014] The beneficial effects of the present invention are: 1.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 11The present invention provides a technical solution: a gasification filter residue roasting device, comprising a roasting furnace body 1, a feed pipe 11 is fixedly inserted at the upper end of the roasting furnace body 1, a material discharge seat 12 is fixedly installed at the lower end of the inner cavity of the roasting furnace body 1, a discharge pipe 13 is fixedly inserted at the bottom of the discharge seat 12, the lower end of the discharge pipe 13 passes downward through the bottom of the roasting furnace body 1 and extends to the outside, a Z-type chain bucket conveyor 14 is installed near the roasting furnace body 1, the feed port of the Z-type chain bucket conveyor 14 is connected to the discharge port of the silo 15, and a cyclone separator 16 is connected to the side of the roasting furnace body 1 through a pipeline; The inner cavity of the roasting furnace body 1 is connected with the feed pipe 11 and the discharge pipe 13 respectively. The upper end of the feed pipe 11 and the lower end of the discharge pipe 13 are both installed with a flip cover. The discharge port of the Z-type chain bucket conveyor 14 is connected to the upper end of the feed pipe 11. The Z-type chain bucket conveyor 14 can transport the gasified filter residue in the silo 15 to the feed pipe 11, and the gasified filter residue falls downward along the feed pipe 11 into the roasting furnace body 1, completing the loading operation.

[0021] The inner cavity of the roasting furnace body 1 is rotatably connected with a central axis 17, which is inserted through and inserted into the material discharge seat 12, and the central axis 17 is rotatably connected to the material discharge seat 12. The central axis 17 is vertically arranged on the roasting furnace body 1, and the lower end of the central axis 17 is driven by the output shaft of a frequency conversion motor fixedly installed at the lower end of the roasting furnace body 1. The inner cavity of the roasting furnace body 1 is equidistantly sleeved with a plurality of furnace beds 2 from top to bottom on the outside of the central axis 17. The furnace beds 2 are fixedly installed in the inner cavity of the roasting furnace body 1. The furnace beds 2 and the central axis 17 are rotatably connected, and a circular hole can also be opened from top to bottom at the center position of the furnace bed 2, and the central axis 17 is arranged in the circular hole so that the central axis 17 can rotate freely.

[0022] The side of the furnace bed 2 is provided with a plurality of material discharge chutes 21 in a circular array, and a conical material guide hopper 23 is fixedly connected to the lower end of the furnace bed 2, so that when the gasified filter residue after roasting falls downward along the material discharge chutes 21, the gasified filter residue will fall into the conical material guide hopper 23, and then slide downward along the conical material guide hopper 23. The conical material guide hopper 23 is distributed in an inverted cone shape, and a material blocking sleeve 24 is fixedly connected to the upper end of the furnace bed 2. The material blocking sleeve 24 is sleeved on the outside of the central axis 17, and the material blocking sleeve 24 is set to prevent the gasified filter residue from contacting the central axis 17, thereby preventing the gasified filter residue from moving to the contact position between the central axis 17 and the furnace bed 2.

[0023] The inner cavity of the roasting furnace body 1 is fixedly connected with an annular fixing plate 3 above each hearth 2, and a limiting mechanism is installed on the inner side of the annular fixing plate 3. A plurality of groups of spreading mechanisms are fixedly installed on the side of the central axis 17 at equal intervals from top to bottom. The spreading mechanisms can be automatically adjusted with the rotation of the central axis 17. The number of groups of spreading mechanisms is consistent with the number of hearths 2, and each group of spreading mechanisms is arranged at the upper end of a corresponding hearth 2.

[0024] See also Figure 4 , Figure 6 and Fig.10 The limiting mechanism includes an annular limiting plate 4 rotatably mounted on the inner side of the annular fixing plate 3, a plurality of limiting teeth 41 are fixedly connected to the inner side of the annular limiting plate 4 in an annular array, one side of the limiting teeth 41 is set as a slope, and the limiting teeth 41 is composed of a right-angled trapezoidal block, and a plurality of fan-shaped slide plates 42 are fixedly connected to the outer side of the annular limiting plate 4 in an annular array, and two fan-shaped extrusion blocks 43 are symmetrically fixedly connected to the lower end of the annular limiting plate 4, and a one-way rotation locking mechanism is symmetrically fixedly connected to the upper end of the annular limiting plate 4.

[0025] An annular groove 31 is formed on the inner side of the annular fixing plate 3 , and the fan-shaped sliding plate 42 is rotatably connected to the annular groove 31 .

[0026] When the annular limiting plate 4 rotates along the inner side of the annular fixing plate 3 , the annular limiting plate 4 drives the fan-shaped slide plate 42 to rotate along the annular groove 31 . The fan-shaped slide plate 42 cooperates with the annular groove 31 , so that the annular limiting plate 4 can rotate stably.

[0027] See also Figure 4 , Figure 5 and Fig.10 The one-way rotation locking mechanism includes a positioning block 5 fixedly connected to the upper end of the annular limiting plate 4. A convex groove 51 is opened inwardly on one side of the positioning block 5 close to the annular fixing plate 3. A convex clamping block 52 is slidably connected in the convex groove 51. A first elastic sheet 53 is fixedly installed on one side of the convex clamping block 52. One side of the first elastic sheet 53 abuts against the innermost side of the convex groove 51.

[0028] A slot 32 is symmetrically provided at the upper end of the annular fixing plate 3. The raised end of the convex clamping block 52 extends through the convex slot 51 to the outside and is clamped with the slot 32. One side of the raised end of the convex clamping block 52 is a slope. The inclination direction of the slope of the raised part of the convex clamping block 52 is opposite to the inclination direction of the slope on one side of the limiting tooth 41, and the two slopes are symmetrical in an eight-shaped shape.

[0029] The first spring piece 53 applies an elastic force to the convex block 52 , and the convex block 52 is inserted into the slot 32 under the action of the elastic force of the first spring piece 53 . At this time, the annular limiting plate 4 cannot rotate clockwise but can only rotate counterclockwise.

[0030] When the annular limiting plate 4 rotates counterclockwise, the annular limiting plate 4 drives the convex clamping block 52 to rotate counterclockwise through the positioning block 5. At this time, the slope of the convex end of the convex clamping block 52 slides along the end of the clamping groove 32, and the convex clamping block 52 is pushed to shrink into the convex groove 51 of the positioning block 5 through the annular fixing plate 3 until the convex end of the convex clamping block 52 is completely moved out of the clamping groove 32. At this time, the convex clamping block 52 squeezes the first spring piece 53, and under the action of the elastic force of the first spring piece 53, the convex clamping block 52 always maintains a tendency to pop outward.

[0031] See also Figure 7 , Fig. 9 and Fig.10 A sealing mechanism is installed in the material discharge chute 21, and the sealing mechanism includes a movable seat 6 slidably installed in the material discharge chute 21, and sliders 61 are symmetrically fixedly connected on both sides of the movable seat 6, and a second elastic piece 62 is fixedly installed on one side of the slider 61. A fan-shaped transmission block 63 is fixedly connected to the upper end of the movable seat 6, and both sides of the fan-shaped transmission block 63 are sloped. The slopes on both sides of the fan-shaped transmission block 63 are in an eight-shaped shape, so that the inner end of the fan-shaped transmission block 63 is successively reduced from the outside to the inside.

[0032] The inner side wall of the material discharge chute 21 is symmetrically provided with a slide groove 22 matching the slider 61 . The slider 61 is slidably connected to the slide groove 22 . One side of the second elastic sheet 62 abuts against the inner side wall of the slide groove 22 .

[0033] When the movable seat 6 slides along the feed chute 21, the movable seat 6 drives the slider 61 to slide along the slide groove 22, so that the movable seat 6 can slide stably, and at the same time prevent the movable seat 6 from falling or moving out of the feed chute 21. In the initial state, the innermost end of the movable seat 6 abuts against the inner end of the feed chute 21, so that the inner end of the feed chute 21 is sealed. At this time, the gasified filter residue cannot fall downward along the feed chute 21.

[0034] When the annular limit plate 4 rotates counterclockwise, it drives the fan-shaped extrusion block 43 to rotate. When one end of the fan-shaped extrusion block 43 contacts the slope of the fan-shaped transmission block 63, the fan-shaped extrusion block 43 continues to rotate. At this time, the fan-shaped extrusion block 43 squeezes the fan-shaped transmission block 63, and the fan-shaped extrusion block 43 pushes the fan-shaped transmission block 63 to move outward. The fan-shaped transmission block 63 drives the movable seat 6 to slide outward along the discharge chute 21. The movable seat 6 drives the slider 61 to slide along the slide groove 22. The slider 61 squeezes the second spring piece 62. The innermost end of the movable seat 6 is separated from the innermost end of the discharge chute 21, and a gap appears. At this time, the gasified filter residue can fall downward along the gap into the conical guide hopper 23.

[0035] When the outermost side of the fan-shaped extrusion block 43 contacts the innermost end of the fan-shaped transmission block 63, the fan-shaped transmission block 63 no longer moves outward, and the movable seat 6 no longer slides outward along the material discharge chute 21. At this time, the gap between the innermost end of the movable seat 6 and the innermost end of the material discharge chute 21 is the largest; When the sector-shaped extruding block 43 is separated from the sector-shaped transmission block 63 , the slider 61 is reset under the action of the elastic force of the second elastic sheet 62 , and the slider 61 drives the movable seat 6 and the sector-shaped transmission block 63 to reset.

[0036] See also Figure 4 , Figure 6 , Figure 8 and Fig.11The material spreading mechanism includes a rotating plate 7 fixedly connected to the side of the central axis 17, the upper end of the rotating plate 7 is recessed downward to open a mounting groove 71, and a fixing block 72 is fixedly connected to the end of the mounting groove 71 close to the outer side, and an upper cover 73 sealing the upper end of the mounting groove 71 is fixedly installed on the upper end of the rotating plate 7, and a rack plate 8 is slidably installed in the mounting groove 71, and a plurality of gear rings 81 are equidistantly meshed on one side of the rack plate 8 with teeth, and a round shaft 82 is inserted and inserted downwardly through the inner side of the gear ring 81, and the gear ring 81 is fixedly sleeved on the upper end of the round shaft 82; The lower end of the circular shaft 82 passes through the bottom of the rotating plate 7 downward and extends to the outside. A limiting ring is fixedly sleeved on the circular shaft 82. The circular shaft 82 is rotatably connected to the rotating plate 7. The gear ring 81 is in rotational contact with the bottom of the mounting groove 71. The limiting ring is in rotational contact with the lower end of the rotating plate 7. The gear ring 81 and the limiting ring cooperate to enable the circular shaft 82 to stably rotate along the rotating plate 7. A material spreading push plate 83 is fixedly installed at the lower end of the circular shaft 82. The material spreading push plate 83 is inclined, and the lower end of the material spreading push plate 83 is in active contact with the upper end of the furnace bed 2. The end of the rack plate 8 close to the outside is fixedly connected to a connecting plate 9, the side of the connecting plate 9 close to the outside is fixedly connected to an extrusion head 91, the side of the connecting plate 9 close to the inside is fixedly installed with a third elastic piece 92, and the extrusion head 91 is arranged on the inner side of the annular limiting plate 4, but the two are not in contact.

[0037] The side of the rack plate 8 away from the teeth is in sliding contact with the inner wall of the mounting groove 71 , and one side of the third elastic sheet 92 is in contact with the fixing block 72 , so that the third elastic sheet 92 applies elastic force to the extrusion head 91 .

[0038] When the central shaft 17 drives the material spreading mechanism to rotate clockwise, the material spreading push plate 83 in the material spreading mechanism rotates clockwise along the upper end of the furnace bed 2. At this time, the material spreading push plate 83 in the material spreading mechanism pushes the gasified filter residue on the upper end of the furnace bed 2 to spread out, and at the same time, the gasified filter residue moves in a spiral shape along the furnace bed 2 toward the center position; When the central shaft 17 drives the material spreading mechanism to rotate counterclockwise, the material spreading push plate 83 in the material spreading mechanism pushes the gasified filter residue to move outward along the furnace bed 2, so that the gasified filter residue moves outward in a spiral shape; When it is necessary to unload the materials, the spreading mechanism rotates counterclockwise, causing the outermost gasified filter residue on the furnace bed 2 to fall downward along the unloading trough 21, and the spreading mechanism pushes the gasified filter residue to move outward in a spiral shape, causing the gasified filter residue to fall downward in sequence. At this time, the gasified filter residue on the inner side of the furnace bed 2 is still spread and pushed by the spreading push plate 83 in the spreading mechanism, so that the gasified filter residue can be fully heated.

[0039] The central shaft 17 drives the spreading mechanism to rotate clockwise or counterclockwise, so that the gasified filter residue can be spread well. The gasified filter residue first moves toward the center along the furnace bed 2, and then moves outward along the furnace bed 2 to prevent the gasified filter residue that has not been baked from falling downward.

[0040] When the material spreading mechanism rotates clockwise, the extrusion head 91 in the material spreading mechanism sequentially squeezes and contacts with the plurality of limiting teeth 41 inside the annular limiting plate 4. At this time, the convex block 52 in the one-way rotation locking mechanism at the upper end of the annular limiting plate 4 is engaged with the card slot 32, and the annular limiting plate 4 does not rotate clockwise. When the material spreading mechanism drives the extrusion head 91 to rotate clockwise, after the extrusion head 91 approaches the limiting teeth 41, the extrusion head 91 first contacts the slope of the limiting teeth 41, and then the extrusion head 91 continues to rotate clockwise, and the extrusion head 91 slides toward the end along the slope of the limiting teeth 41, and is pushed by the limiting teeth 41 to slide into the mounting groove 71 of the rotating plate 7. When the end of the extrusion head 91 contacts the end of the limiting teeth 41, the extrusion head 91 slides the most into the mounting groove 71. When the extrusion head 91 slides into the installation slot 71, the connection plate 9 is driven to move, the connection plate 9 squeezes the third spring piece 92, and the connection plate 9 drives the rack plate 8 to slide inward along the installation slot 71. At this time, the rack plate 8 drives the gear ring 81 to rotate clockwise, and the gear ring 81 drives the material spreading push plate 83 to rotate clockwise through the circular shaft 82; When the extrusion head 91 is separated from the limiting teeth 41, the connecting plate 9 drives the rack plate 8 and the extrusion head 91 to move outward and reset under the action of the elastic force of the third spring piece 92. When the rack plate 8 moves outward, it drives the gear ring 81 to rotate counterclockwise. The gear ring 81 drives the spreading push plate 83 to rotate counterclockwise through the circular shaft 82 to reset, and so on. During the rotation process, the extrusion head 91 is squeezed and contacted with multiple limiting teeth 41, so that the spreading push plate 83 in the spreading mechanism can rotate continuously, which greatly improves the spreading and turning efficiency of the gasification filter residue, so that the gasification filter residue can be fully roasted and oxidized.

[0041] When the material spreading mechanism is to rotate counterclockwise, the extrusion head 91 in the material spreading mechanism should be located near the inner side of the fan-shaped extrusion block 43. The best position is that the extrusion head 91 is located above the center of the inner side of the fan-shaped extrusion block 43. When the material spreading mechanism rotates counterclockwise, when the extrusion head 91 contacts the limiting teeth 41, the side of the extrusion head 91 abuts against the side of the limiting teeth 41 away from the slope. At this time, the extrusion head 91 continues to rotate counterclockwise, which will drive the limiting teeth 41 to rotate counterclockwise synchronously. The limiting teeth 41 drive the annular limiting plate 4 to rotate counterclockwise, and the annular limiting plate 4 drives the fan-shaped extrusion block 43 to rotate synchronously. At this time, the extrusion head 91 will not slide back and forth along the mounting groove 71, and the gasified filter residue is pushed to move outward along the furnace bed 2 through the material spreading push plate 83 in the material spreading mechanism. When the material spreading push plate 83 pushes the gasified filter residue to move to the top of the discharge chute 21, the fan-shaped extrusion block 43 pushes the fan-shaped transmission block 63 to move, and the fan-shaped transmission block 63 drives the movable seat 6 to move, opening the innermost end of the discharge chute 21. At this time, the material spreading push plate 83 pushes the gasified filter residue to fall downward along the discharge chute 21.

[0042] When the material spreading mechanism moves to the vicinity of the corresponding material feeding trough 21, the fan-shaped extrusion block 43 moves synchronously to the vicinity of the material feeding trough 21, and at the same time moves the movable seat 6 in the material feeding trough 21, so that a gap is formed between the movable seat 6 and the innermost end of the material feeding trough 21 for material feeding; When it is necessary to stop feeding, the convex block 52 in the one-way rotation locking mechanism at the upper end of the annular limit plate 4 needs to be engaged with the slot 32; If it is not engaged, when the material spreading mechanism drives the extrusion head 91 to rotate clockwise, the extrusion head 91 will drive the limiting teeth 41 to rotate clockwise for a period of time, and the limiting teeth 41 will drive the annular limiting plate 4 to rotate a certain angle until the convex block 52 in the one-way rotation locking mechanism at the upper end of the annular limiting plate 4 is engaged with the slot 32. At this time, the annular limiting plate 4 can no longer rotate clockwise, and the reset is completed.

[0043] By arranging multiple furnace beds 2 from top to bottom, the gasification filter residue can be well roasted and processed, so that the gasification filter residue can be fully roasted and oxidized. The temperature of the inner cavity of the roasting furnace body 1 can be controlled by zone according to needs. This can be achieved by all existing roasting furnaces and will not be described in detail here.

[0044] Working principle: During operation, the gasified filter residue is added to the uppermost furnace bed 2 through the feed pipe 11 by the Z-type chain bucket conveyor 14. At this time, the central shaft 17 is driven to rotate clockwise by the output shaft of the variable frequency motor, and the central shaft 17 drives the material spreading mechanism to rotate clockwise along the upper end of the furnace bed 2. At the same time, the extrusion head 91 in the material spreading mechanism rotates along the inner side of the limit mechanism, so that the extrusion head 91 is pressed and contacted with the multiple limit teeth 41 in the limit mechanism in turn, so that the material spreading push plate 83 in the material spreading mechanism performs reciprocating forward and reverse rotations. The material spreading mechanism pushes the gasified filter residue to move outward along the furnace bed 2, so that the gasified filter residue moves outward in a spiral shape. The material spreading mechanism rotates counterclockwise and counterclockwise, so that the gasified filter residue can be well spread and turned over, so that the gasified filter residue can be evenly heated.

[0045] When the gasified filter residue needs to fall down to the next furnace bed 2, the output shaft of the frequency conversion motor drives the central shaft 17 to rotate counterclockwise, and the central shaft 17 drives the material spreading mechanism to rotate counterclockwise. When the extrusion head 91 of the material spreading mechanism contacts the limit teeth 41, the side of the extrusion head 91 abuts against the side of the limit teeth 41 away from the slope. At this time, the extrusion head 91 continues to rotate counterclockwise to drive the limit teeth 41 and the annular limit plate 4 to rotate counterclockwise, and the annular limit plate 4 drives the fan-shaped extrusion block 43 to rotate synchronously. When the spreading push plate 83 in the spreading mechanism pushes the gasified filter residue to move above the discharge chute 21, the fan-shaped extrusion block 43 pushes the fan-shaped transmission block 63 to move, and the fan-shaped transmission block 63 drives the movable seat 6 to move, so that a gap is generated between the movable seat 6 and the innermost end of the discharge chute 21. At this time, the spreading push plate 83 pushes the gasified filter residue to fall downward along the discharge chute 21 to the inner cavity of the conical guide hopper 23. The gasified filter residue falls downward along the conical guide hopper 23 to the next furnace bed 2. By arranging multiple furnace beds 2 from top to bottom, the gasified filter residue can be well roasted and processed, so that the gasified filter residue can be fully roasted and oxidized.

[0046] When the gasified filter residue falls downward from the lowest furnace bed 2, the gasified filter residue completes roasting and oxidation. At this time, the gasified filter residue falls downward along the conical guide hopper 23 to the discharge seat 12, and the gasified filter residue slides along the discharge seat 12 to the discharge pipe 13, and finally the gasified filter residue is discharged downward along the discharge pipe 13.
