Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary device for activated carbon production, in particular to a high adaptability feeding device for activated carbon production. Background Technique
[0002] Activated carbon is prepared by pyrolysis and activation of carbon-containing raw materials such as wood, coal and petroleum coke. Activation of activated carbon is one of the most important steps in the production of activated carbon. Activation of activated carbon is generally divided into three main processes according to the temperature change in the thermal decomposition process: drying process, pre-carbonization process, and carbonization process. Different temperatures will be applied in different action stages to precipitate different substances in the activated carbon and increase the fixed carbon content of the charcoal.
[0003] In the carbonization process of charcoal, the pre-carbonized activated carbon needs to be introduced into the secondary activation furnace. However, there are certain problems with both the existing methods of transporting by conveyor belt and by air flow. Whether it is air feeding or conveyor belt feeding, due to the light weight of the activated carbon, it is difficult to control the feeding amount. In the case of more feeding, it will be blocked at the filter screen position of the feeding structure, thus affecting the subsequent feeding, resulting in the accumulation of raw materials at the feeding position and unable to discharge evenly. Content of the Utility Model
[0004] The utility model provides a high adaptability feeding device for activated carbon production, which can perform jitter filtering with corresponding force on the raw materials according to the input amount of the raw materials during the feeding stage, so that the raw materials can be quickly screened and enter the pre-drying device, and can effectively solve the above problems.
[0005] The utility model is realized as follows:
[0006] A high adaptability feeding device for activated carbon production is connected to the front end of an activation furnace. The inside of the activation furnace is hollow. The two sides of the activation furnace are respectively a feeding end and a discharging end. The feeding end of the activation furnace is connected to a pre-drying structure, including:
[0007] An adaptive feeding structure, including a feeding frame communicated with the pre-drying structure. A filter plate is movably arranged in the middle of the feeding frame. A moving member is fixedly connected to both sides of the filter plate. The moving member is movably connected to the inner wall of the feeding frame and extends and is fixed to the interlayer of the feeding frame at the top. A pressurizing member is arranged at the lower end of the filter plate. The pressurizing member is electrically connected to an infrared sensor at the feeding port position of the feeding frame, and the pressurizing member is opened and closed according to the detection amount of the infrared sensor.
[0008] As a further improvement, the moving member includes connecting buckles fixedly connected to both sides of the filter plate. An extension rod is arranged at the top of the connecting buckle. The extension rod extends into an elastic frame in the interlayer, and the elastic frame reciprocates up and down in the interlayer.
[0009] As a further improvement, the extension rod is a U-shaped structure with an opening facing downwards.
[0010] As a further improvement, six connecting buckles are provided. Every three connecting buckles form a group and are respectively arranged on the lateral sides of the filter plate.
[0011] As a further improvement, the elastic frame includes a movable column connected to the bottom of the extension rod. A return spring is connected to the bottom of the movable column, and the bottom of the return spring is connected to a pressing block, which is fixedly connected to the bottom inside the interlayer.
[0012] As a further improvement, the pressure increasing member includes an air inlet chamber arranged at the lower end inside the feeding frame. The air inlet chamber is within the coverage area of the projection of the connecting buckle. The air inlet chamber is connected to an elastic airbag, and the elastic airbag is attached to the lower side of the filter plate after it descends.
[0013] The beneficial effects of the present utility model are as follows:
[0014] In the existing activated carbon feeding equipment, activated carbon is often directly fed into the activation furnace. A large amount of activated carbon with preliminary waste heat is directly stacked in the secondary activation furnace, which extremely affects the effect of secondary activation. Therefore, through the self-adaptive feeding structure provided by the present utility model, first, a filter plate is arranged at the position of the feeding frame to block a large amount of raw materials falling at the same time. At the position of the filter plate, a movable member that can move up and down is arranged. Under the weight of the raw materials, the movable member can drive the entire filter plate to move downward, and the pressure increasing member can continuously deform and push the filter plate upward, so that the particles on the filter plate continuously shake and are evenly output downward. Thus, while the filter plate blocks a large amount of raw materials from pouring into the activation furnace in a short time, it can also feed materials evenly and adapt to different feeding speeds. When feeding a large amount of materials, the deformation amount and change speed of the pressure increasing member are both accelerated, so that the adaptability of the entire feeding structure is higher.
[0015] The entire movable member can drive the filter plate to move. When there is less material, the material will directly pass through the filter plate and be output downward. When there is more material, the filter plate will be pressed downward, causing the connecting buckle and the extension rod to move downward, so that the elastic frame contracts. After a part of the material has been discharged, due to the decrease in pressure, it rebounds upward, thus achieving the effect of moving up and down to shake the material.
[0016] When shaking the material, the material is shaken by the expansion and contraction of the elastic frame. Specifically, the downward movement of the extension rod drives the downward movement of the movable column, thereby driving the compression of the return spring. After the pressure decreases, the return spring will rebound, thus realizing the shaking of the material.
[0017] However, if only light is used to vibrate the material through the reset spring, the effect is very limited. Therefore, the present utility model also improves the vibrating effect by setting a pressurizing member, which changes the position of the filter plate by changing its own volume.

[0026] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more unless otherwise specifically defined.
[0027] Referring to Figures 1 to 6 As shown, a highly adaptable feeding device for activated carbon production is connected to the front end of a pre-drying structure 30 of an activation furnace 10. A plurality of gear rings 11 are fixedly arranged on the outer side of the activation furnace 10. A driving seat 20 meshing with the gear rings 11 is arranged at the bottom of the activation furnace 10. The interior of the activation furnace 10 is hollow. The two sides of the activation furnace 10 are respectively a feed end and a discharge end. It further includes: a pre-drying structure 30, including an inclined trough seat 31 connected to the feed end of the activation furnace 10. A plurality of heaters 32 are arranged at the top of the inclined trough seat 31. A plurality of adjustable material spreading frames 33 are arranged at the bottom of the inclined trough seat 31. A pressure sensor is arranged on the first adjustable material spreading frame 33 counted from top to bottom. A plurality of adjustable material spreading frames 33 are all driven by an adjusting motor 34. The adjusting motor 34 is electrically connected to the pressure sensor. The included angle between the adjustable material spreading frame 33 and the inner bottom of the inclined trough seat 31 is adjusted by the adjusting motor 34 according to the data of the pressure sensor; an adaptive feeding structure 40, including a blanking frame 41 communicating with the pre-drying structure 30. A filter plate 42 is movably arranged in the middle of the blanking frame 41. A moving member 43 is fixedly connected to both sides of the filter plate 42. The moving member 43 is movably connected to the inner wall of the blanking frame 41 and extends to be fixed in the interlayer 44 of the blanking frame 41 at the top. A pressurizing member 45 is arranged at the lower end of the filter plate 42. The pressurizing member 45 is electrically connected to an infrared sensor at the feed inlet position of the blanking frame 41. The pressurizing member 45 is opened and closed according to the detection amount of the infrared sensor.
[0028] In this embodiment, after the activated carbon is dried through the pre-drying structure 30, it is input into the activation furnace 10. Since the gear ring 11 outside the activation furnace 10 meshes with the driving seat 20, the activated carbon will gradually move towards the inner side of the activation furnace 10 under the slow rotation of the activation furnace 10, and the activated carbon after being activated by the activation furnace 10 enters the next step.
[0029] In existing activated carbon feeding equipment, activated carbon is often directly fed into the activation furnace. A large amount of activated carbon with preliminary waste heat directly accumulates in the secondary activation furnace, which extremely affects the effect of secondary activation. Therefore, in this utility model, through the self-adaptive feeding structure 40 provided, first, a filter plate 42 is arranged at the position of the feeding frame 41 to block a large amount of raw materials falling at the same time. At the position of the filter plate 42, a movable part 43 that can move up and down is arranged. The movable part 43 can drive the entire filter plate 42 to move downward under the weight of the raw materials, and the pressurizing part 45 can also continuously deform and push the filter plate 42 upward, so that the particles on the filter plate 42 continuously shake and are evenly output downward. Thus, while the filter plate 42 blocks a large amount of raw materials from surging into the activation furnace in a short time, it can also evenly feed the materials and adapt to different feeding speeds. When feeding a large amount of materials, the deformation amount and change speed of the pressurizing part 45 are both accelerated, so that the adaptability of the entire feeding structure is higher.
[0030] The entire movable part can drive the filter plate 42 to move. Specifically, the movable part 43 includes connection buckles 431 fixedly connected to both sides of the filter plate 42. At the top of the connection buckle 431, an extension rod 432 is arranged. The extension rod 432 extends into an elastic frame 433 in the interlayer 44. The elastic frame 433 reciprocates up and down in the interlayer 44. When the amount of materials is small, the materials will directly pass through the filter plate 42 and be output downward. When the amount of materials is large, the filter plate 42 will be pressed downward, causing the connection buckle 431 and the extension rod 432 to move downward, so that the elastic frame 433 contracts. After a part of the materials are fed, due to the reduction of pressure, it rebounds upward, thus achieving the effect of moving up and down to shake the materials.
[0031] In order to facilitate the accommodation of the extension rod 432 in the interlayer 44 and prevent activated carbon powder from entering the entire movable part 43, the extension rod 432 is a U-shaped structure with an opening downward and is adopted in an external manner, so that the mutual jamming phenomenon between the activated carbon and the moving structure can be greatly reduced.
[0032] In order to improve the stability of the movement of the filter plate 42, six connection buckles 431 are provided. Every three connection buckles 431 are a group and are respectively arranged on the lateral sides of the filter plate 42.
[0033] When vibrating the materials, the vibration is carried out through the expansion and contraction of the elastic frame 433. In this embodiment, the elastic frame 433 includes a movable column 4331 connected to the bottom of the extension rod 432. A return spring 4332 is connected to the bottom of the movable column 4331. The bottom of the return spring 4332 is connected to a pressing block 4333, and the pressing block 4333 is fixedly connected to the bottom inside the sandwich layer 44. Specifically, when the extension rod 432 moves downward, it drives the movable column 4331 to move downward, further driving the compression of the return spring 4332. After the pressure decreases, the return spring 4332 rebounds, thus realizing the vibration of the materials.
[0034] However, if only vibrating the materials through the return spring 4332, the effect is very limited. Therefore, the present utility model also includes a pressure boosting member 45. The pressure boosting member 45 includes an air inlet chamber 451 arranged at the lower inner side of the feeding frame 41. The air inlet chamber 451 is within the coverage of the projection position of the connecting buckle 431. The air inlet chamber 451 is connected to an elastic airbag 452, and the elastic airbag 452 is attached to the lower side of the lowered filter plate 42. By changing the volume of the pressure boosting member 45 itself, the position of the filter plate 42 is changed, thereby improving the effect of vibrating the materials. Specifically, an external air inflation structure is used to inflate the air inlet chamber 451 and inflate the elastic airbag 452. The inflation frequency is intermittent input and output, so as to achieve the effect of reciprocally lifting or lowering the filter plate 42.
[0035] After the speed of the raw materials is adjusted, they will enter the pre-drying structure 30. In the traditional pre-drying step, a slope is set, and the raw materials gradually enter the activation furnace by self-downward movement, so as to achieve the effect of pre-drying. However, in this way, when a large amount of raw materials are fed, the downward speed of the raw materials will not change with the large amount of incoming raw materials, resulting in a poor pre-drying effect for the bottom-layer raw materials. Therefore, with the added pre-drying structure 30 of the present utility model, the raw materials falling into the inclined trough seat 31 can fall onto the adjustable material spreading rack 33. The adjustable material spreading rack 33 is driven by an adjustment motor 34. When the pressure sensor detects a large pressure, the adjustable material spreading rack 33 swings downward to discharge the materials, so that the bottom-layer raw materials can be exposed, and when the pressure is small, it collects the materials upward, increasing the contact time between the raw materials and the hot air and improving the pre-drying effect.
[0036] During the adjustment of the adjustable bulk material rack 33, it relies on the rotation of the adjustment motor 34. Specifically, the adjustable bulk material rack 33 includes a swing shaft rod 331 connected to the adjustment motor 34. The swing shaft rod 331 is closely attached to the bottom inside the inclined groove seat 31. A swing plate 332 is fixed on the swing shaft rod 331. A number of through slots are provided inside the swing plate 332. A blocking structure 333 for adjusting the opening degree of the through slots is arranged on the back side of the swing plate 332. When the adjustment motor 34 rotates, it drives the swing shaft rod 331 to rotate, and then makes the swing plate 332 carrying the raw materials rotate. In fact, through slots are provided on the swing plate 332, allowing a small amount of activated carbon to pass through. However, in the case of a large blockage, the position of the raw materials can be changed by swinging the swing plate 332, so that the raw materials can quickly move downward. In the case of a large accumulation of raw materials, the raw materials can even directly move downward.
[0037] In the case of a small amount of raw materials, they will directly fall through the through slots on the swing plate 332, and the retention effect is poor. Therefore, the blocking structure 333 of the present utility model includes a push rod motor 3331 fixedly connected to the back of the swing plate 332. A blocking plate 3332 is connected to the output end of the push rod motor 3331. The blocking plate 3332 is provided with a blocking groove opposite to the through slot. By providing the blocking structure 333 on the back of the swing plate 332, the position of the blocking plate 3332 can be adjusted by the push rod motor 3331 in the blocking structure 333, so that the blocking groove of the blocking plate 3332 and the through slot of the swing plate 332 form a certain opening degree. When feeding a small amount, the opening degree can be made smaller, so that the raw materials can be pre-dried for a longer time.
[0038] On the swing plate 332, there are provided jumping columns 334 that can jump. A number of jumping columns 334 are provided on the front surface of the swing plate 332. The jumping columns 334 and the through slots are arranged alternately. The jumping column 334 includes a fixed seat 3341 fixedly connected to the front surface of the swing plate 332. A convex block 3342 is movably arranged in the fixed seat 3341. The inner side of the convex block 3342 is connected to the bottom surface of the fixed seat 3341 through a compression spring 3343. When there is a lot of material, the jumping column 334 can be pressed down. When there is less material, due to the reduction of pressure, it will undergo a certain deformation by itself, and then shake the material forward, thus preventing the material from stagnating in place. The fitting between the convex block 3342 and the fixed seat 3341 can prevent activated carbon from falling into the gap between the two.
[0039] In order to make the effect of the swing plate 332 reach the best, the swing angle of the swing plate 332 is -25° to 60°.
[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
