Description

Technical Field

[0001] This utility model relates to the field of briquette activated carbon preparation technology, specifically a feeding device for a vertical furnace of briquette activated carbon. Background Technology

[0002] Briquetting activated carbon is a technical term, not referring to the macroscopic shape commonly perceived, but rather to a granulation process for activated carbon. The production method of briquetted, irregularly shaped, crushed activated carbon is as follows: its components and proportions (by weight) are: 70%-80% weakly caking coal, 8%-22% coking coal, and 8%-12% coal tar pitch. When producing briquetted activated carbon using a vertical furnace, the materials need to be screened.

[0003] For example, the authorization announcement number "CN109876887A" is named a feeding device for a vertical furnace of briquetted activated carbon. The material in the feeding box is guided by a guide plate and crushed again. Then, the first electric push rod drives the feeding box to move down to its original position. This saves labor, has low cost, and has a simple structure. The existing feeding device for vertical furnace of briquetted activated carbon uses multi-stage screens to screen the carbon raw materials. Finally, the sorted raw materials are put back into the crushing device for secondary crushing. Therefore, the feeding process of a batch of carbon raw materials is too complicated and lengthy, and the feeding time is too long, which directly affects the feeding efficiency of the feeding device for vertical furnace of briquetted activated carbon, which is relatively low.

[0004] Meanwhile, the existing feeding devices for briquette activated carbon vertical furnaces are generally located near the high-temperature combustion chamber of the combustion furnace because the briquette activated carbon needs to be screened and then directly fed into the combustion chamber. This causes the various structural components of the feeding device to work in a high-temperature environment for a long time, which has a significant aging effect on the outer shell and components of the feeding device and is not conducive to maintaining the service life of the briquette activated carbon vertical furnace feeding device. Utility Model Content

[0005] The purpose of this invention is to solve the problems of the excessively complex and lengthy feeding process for a batch of carbon raw materials in existing vertical furnaces for briquetted activated carbon, the long intervals between feeding, which directly affect the low feeding efficiency of the feeding device and the fact that the feeding device is generally located near the high-temperature combustion chamber of the combustion furnace, which causes the various structures and equipment of the feeding device to work in a high-temperature environment for a long time, which is not conducive to the service life. Therefore, this invention proposes a feeding device for vertical furnaces for briquetted activated carbon.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A feeding device for a vertical furnace of briquetted activated carbon is designed, including a feeding box, a furnace body, and a feeding hopper. The feeding hopper is fixedly installed on one side of the top of the feeding box. The feeding box is movably installed above the furnace body. A unified extrusion and crushing structure for activated carbon is provided above the feeding box. A secondary sieving structure is fixedly installed on the inner wall of the feeding box. An anti-scalding feeding device is provided at the bottom of the feeding box.

[0008] Preferably, the activated carbon uniform extrusion and crushing structure includes a guide slope and hydraulic cylinders. The guide slope is fixedly installed on the upper part of the inner wall of the feed box. Multiple hydraulic cylinders are fixedly connected to the top of the feed box. Lifting plates are fixedly connected to the lower ends of the multiple hydraulic cylinders. Rotating rollers are rotatably connected to the inner walls of two lifting plates through bearings. A crushing layer is fixedly sleeved on the outer walls of the multiple rotating rollers. Multiple crushing motors are fixedly installed on the side walls of the lifting plates.

[0009] This feature includes a smooth top surface on the guide slope, allowing the briquetted activated carbon raw material to slide down the slope at a uniform speed after being poured into the hopper. The crushing motor drives the rotating roller, which in turn rotates the outer crushing layer, crushing the briquetted activated carbon raw material sliding down the guide slope. The processed activated carbon raw material is crushed into uniform shapes and then continuously discharged downwards. Because the crushed activated carbon is uniform in size, it does not require a secondary or repeated crushing process, ensuring one-time crushing and accelerating the crushing speed.

[0010] Preferably, the outer walls of the plurality of compaction layers are movably connected to the upper surface of the guide slope, the upper end of the guide slope is disposed opposite to the lower part of the feeding hopper, and the output shafts of the plurality of crushing motors are fixedly connected to the ends of the rotating rollers.

[0011] Preferably, the anti-scalding feeding device includes a feeding trough and a pad. The feeding trough is fixedly installed on the lower inner side of the feeding box. The lower end of the feeding trough is fixedly connected to a feeding pipe. An extension frame is fixedly connected to the outer wall of the feeding pipe. Multiple heat dissipation fins are fixedly installed on the side walls of the two extension frames. The pad is threadedly connected to the upper end of the vertical furnace body by bolts. A heat insulation layer is fixedly connected to the top of the pad.

[0012] This feature includes multiple vertical copper heat dissipation fins welded to the outside of the extension frame. These fins diffuse some of the heat generated by combustion inside the vertical furnace upwards, reducing the direct flow of heat into the feed box via the feeding pipe. The pads are bolted to the top of the feed box for installation and removal. A heat-resistant and flame-retardant EVA foam is fixedly connected in the middle of the pads, preventing some heat from being transferred upwards to the feed box along the pad connection. Therefore, the feed box can maintain a certain temperature for long-term activated carbon feeding with minimal impact on internal parts and components.

[0013] Preferably, the lower end of the feeding pipe is connected to the upper part of the vertical furnace body, and the top ends of the plurality of heat insulation layers are fixedly connected to the lower end of the feeding box.

[0014] This setting features a funnel-shaped feeding trough at the bottom of the feed box, which guides the sieved and pulverized activated carbon downwards into the feeding pipe, which connects the vertical furnace body below and the feed box above.

[0015] Preferably, the secondary screening structure includes a screening plate and a slag removal door. The screening plate is fixedly connected to the other end of the inner wall of the feed box. A vibration motor is fixedly installed at the end of the screening plate. The vibration motor is fixedly connected to the outside of the feed box. The slag removal door is rotatably connected to the outer wall of the feed box via a hinge. A handle is fixedly connected to the outside of the slag removal door. A reserved hole is fixedly opened on the outer wall of the feed box.

[0016] This setup uses a stainless steel mesh screen plate with a slight rightward tilt. The crushed activated carbon raw material slides onto the screen plate. With the start of the vibrating motor, the screen plate is subjected to vibration, causing qualified raw materials to fall downwards. Impurities or hard, uncompressed carbon materials slide down the slope of the screen plate and accumulate inside the slag removal door. Workers can periodically pull the slag removal door outwards through the pre-drilled hole, allowing large impurities accumulated above the inclined screen plate to be removed. This prevents substandard raw materials from entering the vertical furnace body below.

[0017] The present invention proposes a feeding device for a vertical furnace of briquetted activated carbon, which has the following advantages: the top of the guide slope has a relatively smooth surface, which facilitates the briquetted activated carbon raw material to slide down the guide slope at a uniform speed after being poured into the feeding hopper. The crushing motor can drive the rotating roller to rotate, and the rotating roller will drive the outer crushing layer to rotate, crushing the briquetted activated carbon raw material sliding down the guide slope. The activated carbon raw material can be crushed into a uniform size and then continuously discharged downwards. Because the crushed activated carbon is uniform in size, it does not need to undergo a secondary or repeated crushing process, which can ensure one-time crushing and speed up the crushing speed.

[0018] The feeding trough is a funnel-shaped structure at the bottom of the feeding box, which guides the sieved and crushed activated carbon downwards into the feeding pipe. The feeding pipe connects the vertical furnace body below and the feeding box above. An extension frame is horizontally welded to the outer wall of the feeding pipe. Multiple vertical copper heat dissipation fins are welded to the outside of the extension frame. When the heat generated by combustion inside the vertical furnace body is transferred upwards, the heat dissipation fins can diffuse some of the heat outwards first, reducing the amount of heat that directly enters the feeding box along the feeding pipe. The spacer block can be installed and removed from the top of the feeding box by bolts. A heat-resistant and flame-retardant EVA foam flame-retardant material is fixedly connected in the middle of the spacer block, which can block a certain amount of heat from being transferred upwards to the feeding box along the spacer block connection. Therefore, the feeding box can maintain a certain temperature for long-term activated carbon feeding, with less impact on internal parts and components, thus improving service life.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] Example:

[0028] Please see Figure 1-6In this embodiment, a feeding device for a vertical furnace of briquetted activated carbon includes a feeding box 1, a vertical furnace body 2, and a feeding hopper 3. The feeding hopper 3 is fixedly installed on one side of the top of the feeding box 1. The feeding hopper 3 is made of stainless steel and is designed with an upward opening to facilitate the dumping of large pieces of briquetted activated carbon raw materials. The feeding box 1 is movably installed above the vertical furnace body 2. The feeding box 1 is made of sturdy stainless steel that is not easy to disintegrate. The top of the feeding box 1 is provided with a uniform extrusion and crushing structure 4 for activated carbon. The inner wall of the feeding box 1 is fixedly installed with a secondary sieving structure 5. The bottom of the feeding box 1 is provided with an anti-scalding feeding device 6.

[0029] The activated carbon unified extrusion and crushing structure 4 includes a guide slope 41 and hydraulic cylinders 42. The guide slope 41 is fixedly installed above the inner wall of the feed box 1 and is obliquely welded to one side of the inner wall of the feed box 1. The top of the guide slope 41 has a relatively smooth slope surface to facilitate the uniform sliding of the activated carbon raw material into the feed hopper 3 along the guide slope 41 after it is poured in. Multiple hydraulic cylinders 42 are fixedly connected to the top of the feed box 1, and the lower ends of the multiple hydraulic cylinders 42 are fixedly connected to lifting plates 43. The hydraulic cylinders 42 are arranged in two parallel rows, so the hydraulic cylinders 42 can pull the lower lifting plates 43 to drive the horizontal rotating rollers 45 to rise and fall vertically above the guide slope 41. This can adjust the height of the lowest end of the crushing layer 46 from the upper surface of the guide slope 41 until the height can crush the activated carbon within a reasonable range. After the activated carbon raw material is connected to the power supply, multiple crushing motors 44 on one side are started. The crushing motors 44 can drive the rotating rollers 45 to rotate, and the rotating rollers 45 will drive the outer crushing layer 46 to rotate, crushing the briquetted activated carbon raw material that slides down the guide slope 41. The activated carbon raw material can be crushed into a uniform shape and then continuously discharged downwards. Because the crushed activated carbon is uniform in size, it does not need to undergo a secondary or repeated crushing process, which can ensure one-time crushing and speed up the crushing speed. The inner walls of the two lifting plates 43 are rotatably connected to the rotating rollers 45 through bearings. The outer walls of the multiple rotating rollers 45 are fixedly sleeved with the crushing layer 46. Multiple crushing motors 44 are fixedly installed on the side walls of the lifting plates 43. The multiple crushing motors 44 are selected as servo motors.

[0030] The outer walls of multiple compaction layers 46 are movably connected to the upper surface of the guide slope 41, the upper end of the guide slope 41 is positioned opposite to the lower part of the feeding hopper 3, and the output shafts of multiple crushing motors 44 are fixedly connected to the end of the rotating roller 45.

[0031] The anti-scalding feeding device 6 includes a feeding trough 61 and a pad 65. The feeding trough 61 is fixedly installed on the inner side of the lower end of the feeding box 1. The feeding trough 61 has a funnel-shaped structure at the bottom of the feeding box 1, which allows the sieved and pulverized activated carbon to be guided downward into the feeding pipe 62. The lower end of the feeding trough 61 is fixedly connected to the feeding pipe 62, which connects the lower vertical furnace body 2 and the upper feeding box 1. An extension frame 63 is fixedly connected to the outer wall of the feeding pipe 62. The extension frame 63 is horizontally welded to the outer wall of the feeding pipe 62. Multiple vertical copper heat dissipation fins 64 are welded to the outside of the extension frame 63. When the heat dissipation fins 64 transfer the heat generated by combustion inside the vertical furnace body 2 upward, they first... A portion of the heat is diffused outwards, reducing the direct entry of heat into the feed box 1 along the feeding pipe 62. Multiple heat dissipation fins 64 are fixedly installed on the side walls of the two extension racks 63. The pad 65 is connected to the upper end of the vertical furnace body 2 by bolts. The pad 65 can be installed and removed from the top of the feed box 1 by bolts. A heat-resistant and flame-retardant EVA foam flame-retardant material is fixedly connected in the middle of the pad 65, which can block a certain amount of heat from being transferred upwards to the feed box 1 along the connection of the pad 65. Therefore, the feed box 1 can maintain a certain temperature for long-term activated carbon feeding with minimal impact on internal parts and components. A heat insulation layer 66 is fixedly connected to the top of the pad 65.

[0032] The lower end of the feeding pipe 62 is connected to the upper part of the vertical furnace body 2, and the top of the multiple heat insulation layers 66 is fixedly connected to the lower end of the feeding box 1.

[0033] The secondary screening structure 5 includes a screening plate 51 and a slag removal gate 54. The screening plate 51 is fixedly connected to the other end of the inner wall of the feed box 1. The screening plate 51 is a stainless steel mesh plate and has a certain rightward tilt angle. This allows the crushed activated carbon raw material to slide onto the screening plate 51. With the start of the vibration motor 52, the screening plate 51 is subjected to the vibration force output by the vibration motor 52, shaking the qualified raw material downwards, while some impurities or hard, uncompressed carbon materials slide down the slope of the screening plate 51 and accumulate. Inside the slag removal door 54, the operator can grip the handle 55 every so often and pull the slag removal door 54 outward along the reserved hole 53 to open it, making it easier to remove large pieces of impurities accumulated above the inclined screening plate 51. This prevents substandard raw materials from entering the vertical furnace body 2 below. A vibration motor 52 is fixedly installed at the end of the screening plate 51 and is fixedly connected to the outside of the feed box 1. The slag removal door 54 is rotatably connected to the outer wall of the feed box 1 via a hinge. A handle 55 is fixedly connected to the outside of the slag removal door 54, and a reserved hole 53 is fixedly opened on the outer wall of the feed box 1.

[0034] Working principle:

[0035] The feeding device for briquetted activated carbon vertical furnace is set at the top of the vertical furnace. The prepared activated carbon material is guided into the vertical furnace below by crushing, grinding and screening the briquetted activated carbon raw material inside the feeding box of the feeding device.

[0036] The guide slope 41 is obliquely welded to one side of the inner wall of the feed box 1. The top of the guide slope 41 has a relatively smooth slope surface, which makes it easy for the briquetted activated carbon raw material to slide down the guide slope 41 at a uniform speed after being poured into the feed hopper 3. The hydraulic cylinders 42 are set in two parallel rows. Therefore, the hydraulic cylinders 42 can pull the lower lifting plate 43 to drive the horizontal rotating roller 45 to rise and fall vertically above the guide slope 41. This can adjust the height of the lowest end of the crushing layer 46 from the upper surface of the guide slope 41 until the height can crush the activated carbon raw material within a reasonable range. Then, the power supply is connected to start multiple crushing motors 44 on one side. The crushing motors 44 can drive the rotating roller 45 to rotate, and the rotating roller 45 will drive the outer crushing layer 46 to rotate, crushing the briquetted activated carbon raw material sliding down the guide slope 41. The activated carbon raw material can be crushed into a uniform shape and then continuously discharged downwards. Because the crushed activated carbon is uniform in size, it does not need to undergo a secondary or repeated crushing process, which can ensure one-time crushing and speed up the crushing speed.

[0037] The feeding trough 61 is a funnel-shaped structure at the bottom of the feeding box 1, which guides the pulverized activated carbon after sieving downward into the feeding pipe 62. The feeding pipe 62 connects the vertical furnace body 2 below and the feeding box 1 above. The extension frame 63 is horizontally welded to the outer wall of the feeding pipe 62. Multiple vertical copper heat dissipation fins 64 are welded to the outside of the extension frame 63. When the heat generated by combustion inside the vertical furnace body 2 is transferred upward, the heat dissipation fins 64 can diffuse some of the heat outward first, reducing the heat from directly entering the feeding box 1 along the feeding pipe 62. The pad 65 can be installed and removed from the top of the feeding box 1 by bolts. A heat-resistant and flame-retardant EVA foam flame-retardant material is fixedly connected in the middle of the pad 65, which can block a certain amount of heat from being transferred upward along the connection of the pad 65 to the feeding box 1. Therefore, the feeding box 1 can maintain a certain temperature for a long time to feed activated carbon, with less impact on internal parts and components, and improved service life.

[0038] The screening plate 51 is a stainless steel mesh plate with a certain rightward tilt angle. The crushed activated carbon raw material slides onto the screening plate 51. With the start of the vibration motor 52, the screening plate 51 is subjected to the vibration force output by the vibration motor 52, shaking the qualified raw material to the bottom. Some impurities or hard, uncompressed carbon materials slide down the slope of the screening plate 51 and accumulate inside the slag removal door 54. Every once in a while, the operator can squeeze the handle 55 and pull the slag removal door 54 outward along the reserved hole 53 to open it, so as to remove the large impurities accumulated above the inclined screening plate 51. This prevents substandard raw materials from entering the vertical furnace body 2 below.
