Description

Technical Field

[0001] The invention relates to the technical field of mesh belt kilns, in particular to a catalyst carrier mesh belt kiln. Background Art

[0002] Nitrogen oxides are one of the important factors affecting the environment. They can cause acid rain, ozone layer depletion, light pollution and other problems. In the industrial production process, the nitrogen oxides produced by industrial boilers, coal-fired power plants, etc. can be denitrated with a high efficiency through ammonia selective catalytic reduction technology. In the above denitration process, the required catalyst is mostly a honeycomb structure, and is attached to the honeycomb carrier through different adhesives, coating slurries, and powder catalysts. After the carrier is dried, it is sent to a calcination furnace for calcination to obtain a honeycomb denitration catalyst.

[0003] In order to achieve a better roasting effect, a mesh belt kiln is often used. However, the mesh belt carrier of the prior art is integrated. The roasting and drying are achieved by laying the catalyst on the mesh belt carrier. When this integrated mesh belt carrier structure is used, due to its large area and the large amount of catalyst spread, it is easy to cause uneven roasting or drying, and it is not easy to perform subsequent maintenance, which in turn affects the use effect and service life of the device. After the catalyst is spread, the traditional mesh belt carrier cannot change the position of the catalyst, cannot achieve the catalyst promotion effect, and cannot realize the cyclic roasting or drying of the catalyst according to demand. It can only be carried out One-time transmission roasting or drying has poor effect of roasting or drying, which causes the catalyst roasting to be not thorough enough or the drying effect to be poor. In addition, the traditional mesh belt kiln usually spreads the catalyst on the mesh belt manually before processing. The manual spreading method easily causes uneven spreading thickness, and the spreading thickness cannot be accurately controlled, resulting in different catalyst stacking thicknesses, which affects the roasting or drying effect of catalysts at different positions of the stacking thickness. The traditional mesh belt is all metal, and it will absorb a lot of heat during the transmission process in the kiln. Both ends of the mesh belt are also in contact with the external environment, so it will lead to energy waste.

[0036] The magnetic conductive mechanism includes a plurality of heat conductive plates 7 fixedly mounted on the conveyor mesh belt 2.

When the catalyst at this place is completed roasting or drying, under the action of the driving element 4, the conveyor mesh belt 2 is made to reciprocate, thereby making the parts of the magnetic conductive mechanism that were previously connected to each other move away from each other, and a new magnetic conductive mechanism is generated, and the catalyst in the new connected part is roasted or dried again, thereby achieving the effect of segmented roasting or drying.

[0040] Example 2

[0041] See also Figure 1 - Fig.10Based on Example 1, the pushing mechanism includes a first connecting plate 13, and the bottom of the first connecting plate 13 is rotatably connected to an adjustable push plate 14 through a first rotating rod 15. The adjustable push plate 14 is rotatably connected to the first connecting plate 13 through the first rotating rod 15, and the angle of the adjustable push plate 14 can be easily adjusted, which can not only adapt to the pushing effect on the catalyst, but also prevent the paving thickness of the catalyst from being affected during recovery. A connecting rod 12 is provided on the side of the adjustable push plate 14, and one end of the connecting rod 12 is fixedly connected to the moving block 11, and the other end of the connecting rod 12 is connected to the moving block 11 through the first rotating rod 15. The second rotating rod 17 is rotatably connected with a hinge seat 16, and the bottom end of the hinge seat 16 is slidably sleeved on the side of the adjustable push plate 14. When the moving block 11 moves, the connecting rod 12 can be driven to move. The connecting rod 12 can pull or push the adjustable push plate 14 through the hinge seat 16 and the second rotating rod 17. The inner cavity of the moving block 11 is provided with a second threaded screw 10, one end of the second threaded screw 10 is fixedly connected to the first connecting plate 13, and the other end of the second threaded screw 10 is provided with a driving component; the driving component includes a rotatable sleeve on the second threaded screw 10 away from the first connecting plate The block 22 at one end of the plate 13 is provided with a smooth inwardly concave groove at one end of the second threaded screw 10 away from the first connecting plate 13, and the block 22 is located at the periphery of the oblique groove. By setting the oblique groove, not only can the block 22 be limited, but also the second threaded screw 10 and the block 22 can be rotated and sleeved with each other to avoid motion interference and ensure the smooth use of the device. The side of the block 22 is provided with a first conical tooth 19, and the side of the first conical tooth 19 is fixedly connected to the end of the second threaded screw 10 that passes through the block 22, and the side of the first conical tooth 19 A second conical tooth 18 is meshed and connected, and a third rotating rod 9 is fixedly sleeved on the side of the second conical tooth 18. A rotating motor 5 is fixedly installed on the top of the third rotating rod 9. The rotating motor 5 can provide power support for the rotation of the third rotating rod 9, and further provide power support for the angle adjustment of the adjustable push plate 14. The side of the clamping block 22 is fixedly connected to a connecting block 21 through a fixing rod 20, and the side of the connecting block 21 is fixedly connected to a cylinder 8. The movable end of the cylinder 8 is the piston rod of the cylinder 8. The piston rod is fixedly connected to the connecting block 21, so as to achieve the effect of pushing and contraction.

[0042] Specifically, under the action of the cylinder 8, the catalyst can be pushed by the adjustable push plate 14, and at the same time, the movable block 11 can be driven to move in the opposite direction under the action of the rotating motor 5, so that the adjustable push plate 14 is tilted, thereby preventing the adjustable push plate 14 from pushing or contacting the catalyst in the opposite direction during the recovery process, thereby reducing the impact on the catalyst paving thickness. At the same time, when resetting, the current part of the catalyst can be pulled backwards by the adjustable push plate 14 according to the required roasting or drying effect of the catalyst, thereby changing the position of the current part of the catalyst on the conveyor mesh belt 2, realizing the need for repeated roasting or drying of the catalyst at the current position, and further improving the roasting or drying effect of the catalyst.

[0043] See also Fig. 9 The flattening mechanism includes a support frame 23 fixedly mounted on the side of the kiln body 1, the support frame 23 is fixedly connected to the kiln body 1 through a support foot, a second connecting plate 24 is slidably sleeved on the side of the support frame 23, a through hole is opened on the side of the support frame 23, the second connecting plate 24 can slide in the through hole, so as to achieve the function of height adjustment, the side of the second connecting plate 24 is fixedly mounted on the inner cavity of the support frame 23 by a first bolt 26, and the bottom of the second connecting plate 24 is fixedly connected with a scraper 25 by a second bolt 27. When in use, the scraper 25 can contact the catalyst, so as to control the thickness of the catalyst entering the inner cavity of the preheating chamber 101, ensure the roasting or drying effect of the catalyst, and prevent the catalyst from being stacked together, which is not conducive to roasting and drying.

[0044] See also Figure 1 , Figure 2 and Fig.10The kiln body 1 is provided with a preheating bin 101, a heating bin 102 and a discharge bin 103. The bottom of the preheating bin 101 and the heating bin 102 are provided with a filter plate 28, which is installed at the top of the inner cavity of the kiln body 1 to filter the dust on the catalyst after roasting. The top of the inner cavity of the heating bin 102 and the preheating bin 101 is provided with an induced draft fan 29, one end of the induced draft fan 29 is located at the top of the inner cavity of the heating bin 102, and the other end of the induced draft fan 29 is located at the top of the inner cavity of the preheating bin 101. The bottom of the preheating bin 101 and the heating bin 102 A rising blower 31 is provided for blowing the hot air. When the hot air flow enters the top of the heating bin 102, the hot gas gathered at the top of the inner cavity of the heating bin 102 is absorbed through the air suction port of the induced draft fan 29, and discharged from the top of the inner cavity of the preheating bin 101 through the air outlet. The air outlet and the air suction port of the induced draft fan 29 are fixedly connected by a connecting pipe 30, thereby realizing preheating and drying of the catalyst located in the inner cavity of the preheating bin 101, reducing the duration of subsequent roasting heating, reducing the subsequent drying effect, and improving the efficiency of drying and roasting. The blower 31 is fixedly installed at the bottom end of the inner wall of the kiln body 1, and the blower 31 is located at the center of the conveyor mesh belt 2. At the same time, the blower 31 can blow on the top of the heating bin 102 to make the hot gas rise. Under the action of the induced draft fan 29 and the blower 31, the circulation of hot gas between the heating bin 102 and the preheating bin 101 can be realized, and the hot gas in the inner cavity of the heating bin 102 can be transported into the inner cavity of the preheating bin 101, so as to continuously preheat the catalyst in the preheating bin 101, reduce the loss of hot gas, and improve the utilization rate of hot gas.

[0045] In this embodiment, the setting of the pushing mechanism not only plays a role in angle adjustment, but also enables the bottom end of the adjustable push plate 14 to form an angle with the top of the conveyor mesh belt 2. At this time, the bottom end of the adjustable push plate 14 and the top of the conveyor mesh belt 2 are in contact with each other. Under the action of the cylinder 8, the catalyst is pushed, so that the catalyst enters the inner cavity of the heating bin 102 from the preheating bin 101 for heating. At the same time, the hot flow gas in the inner cavity of the heating bin 102 enters the inner cavity of the preheating bin 101 to preheat the catalyst to be treated. This preheating method can remove moisture from the catalyst and improve subsequent treatment efficiency. The adjustable push plate 14 can be reset after being pushed to achieve the next pushing requirement. When resetting, reverse adjustment can be performed to prevent the adjustable push plate 14 from affecting the state of the spread catalyst during movement, thereby ensuring the roasting or drying effect of the current part of the catalyst.

[0046] Example 3

[0047] See also Figure 3 and Figure 4Based on Example 1 and Example 2, an adjustment component is provided in the inner cavity of the kiln body 1, and the adjustment component includes a plurality of extrusion rods 32 located on both sides of the conveyor mesh belt 2, and a second sliding rod 33 is provided on the side of the extrusion rod 32, and the second sliding rod 33 is slidably sleeved on the inner wall of the kiln body 1, and a fixed block 34 is fixedly sleeved on the periphery of the second sliding rod 33, and a rotating block 35 is rotatably sleeved on the top periphery of the fixed block 34, and a third bolt 36 is fixedly connected to the top of the rotating block 35, and the third bolt 36 is threadedly rotatably sleeved on the inner cavities on both sides of the kiln body 1.

[0048] In this embodiment, by adjusting the third bolt 36, the bottom end of the third bolt 36 is rotated on the top of the fixed block 34, so that the fixed block 34 can be pushed. The fixed block 34 is forced downward to push the second sliding rod 33, thereby driving the extrusion rod 32 to adjust up and down, and further adjusting the contact distance between the extrusion rod 32 and the two sides of the conveyor mesh belt 2, so as to achieve the adjustment of the parallel state of the conveyor mesh belt 2, so that a part of the conveyor mesh belt 2 is in a state with a fluctuating section, so that the catalyst located in this part rolls, so that the catalyst at different upper and lower positions can be adjusted to achieve the turning effect of the catalyst, and then the stacked catalysts can be evenly roasted or dried, thereby improving the roasting and drying effects.

[0049] The working principle of the present invention is: when it is necessary to use this device, the catalyst that needs to be calcined or dried can be first spread on the conveyor mesh belt 2. At this time, the conveyor mesh belt 2 can be driven to reciprocate by the driving element 4. During the movement of the conveyor mesh belt 2, the catalyst at the feed end can be driven to move, and the flattening mechanism can be adjusted according to the calcination or drying requirements of the catalyst, and then the contact distance between the scraper 25 and the catalyst can be adjusted to achieve the spreading effect of the catalyst on the conveyor mesh belt 2, and reduce the thickness of the superimposed stacking of the catalyst, thereby improving the calcination or drying effect of the catalyst.

[0050] When the catalyst enters the preheating chamber 101 of the inner cavity of the kiln body 1 driven by the conveyor mesh belt 2, a first conductive block 701 on the side of the conveyor mesh belt 2 moves to the side of the second conductive block 602, so that the first magnetic block 704 and the second magnetic block 606 contact each other, thereby achieving the effect of magnetic attraction and electrification, and transmitting it to the heat conduction plate 7 through the first conductive block 701, so as to realize the electrification of the current part of the conveyor mesh belt 2. Since the conveyor mesh belt 2 has the characteristics of high temperature resistance, thermal conductivity and non-deformation, it can roast or dry the current part of the catalyst. At this time, the second conical teeth 18 and the first conical teeth 19 can be driven to rotate by driving the rotating motor 5, thereby driving the second threaded screw 10 to rotate, and the rotation of the second threaded screw 10 can drive the moving block 11 to rotate. The adjustable push plate 14 can be moved, and then the angle of the adjustable push plate 14 can be adjusted through the connecting rod 12, the hinge seat 16 and the second rotating rod 17. At the same time, the driving cylinder 8 can push the calcined or dried catalyst through the adjustable push plate 14, so that the current part of the catalyst enters the inner cavity of the discharge bin 103, so that the rising hot air flow after the calcination or drying rises and passes through the filter plate 28 to be filtered into the preheating bin 101 and the heating bin 102 and the top of the inner cavity. Under the action of the induced draft fan 29 and the blower 31, the circulation of hot gas between the heating bin 102 and the preheating bin 101 can be realized, and the hot gas in the inner cavity of the heating bin 102 can be transported into the inner cavity of the preheating bin 101, so that the catalyst in the preheating bin 101 is continuously preheated, and the loss of hot gas is reduced, thereby improving the utilization rate of the hot gas. When the conveyor mesh belt 2 moves to the position of the adjustment component, the contact distance between the extrusion rod 32 and the conveyor mesh belt 2 can be adjusted by adjusting the third bolt 36, so as to realize the tilt adjustment of the surface of the conveyor mesh belt 2 located therein, so as to facilitate the stacked catalyst to be turned upside down, so that the upper and lower parts of the stacked catalyst can contact the conveyor mesh belt 2, so as to realize the roasting or drying after power-on, and improve the uniformity of the roasting or drying of the catalyst. With the movement of the conveyor mesh belt 2, the synchronous block 605 can be driven to move around the periphery of the first threaded screw 601 by driving the servo motor 603, so as to drive the second conductive block 602 to move, so that the second magnetic block 606 and the first magnetic block 7 04 moves synchronously, thereby increasing the contact time between the first magnetic block 704 and the second magnetic block 606, thereby increasing the power-on time, and improving the roasting or drying effect of the catalyst in this part. When the first magnetic block 704 of this part is away from the second magnetic block 606, driving the servo motor 603 again can drive the second magnetic block 606 to return to its original position. At this time, it just continues to be magnetically connected with the first magnetic block 704 and energized, so as to realize the roasting or drying of the catalyst in this part. By setting the conveyor mesh belt 2 to a state where it can be powered on in sections, the catalysts at different positions can be roasted or dried in sections, and the generation of dust can be reduced, thereby further improving the roasting and drying effects of the catalyst.
