Technical Field

[0001] The invention relates to the field of granulation equipment, in particular to spherical activated carbon granulation equipment. Background Art

[0002] Spherical activated carbon is an activated carbon material with a spherical appearance. Compared with traditional irregularly shaped activated carbon, spherical activated carbon has better fluidity and filling properties. Spherical activated carbon can provide a large number of adsorption sites and has a strong adsorption capacity for various pollutants.

[0003] At present, spherical activated carbon is mainly processed by granulators, which are divided into disc granulators, extrusion granulators, high-speed rotary granulators, fluidized bed granulators, etc. Among them, when the extrusion granulator processes spherical activated carbon, the stirred activated carbon raw materials and adhesives are first added into the equipment, and then the activated carbon raw materials are squeezed into strips by extrusion or rolling, and then the strips are divided into small sections by cutting or crushing, and finally spherical particles are formed by subsequent treatment such as rolling.

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0033] See also Figure 1 and Figure 2 A spherical activated carbon granulation equipment includes an outer shell 1, a feeding port is arranged at the upper part of the outer shell 1, a discharging port is arranged at the lower part of the outer shell 1, an extrusion mechanism 2 for extruding the activated carbon raw material into a spherical shape is arranged at the upper part of the outer shell 1, and a solid mechanism 3 for fixing the shape of the spherical activated carbon is arranged at the lower part of the outer shell 1.

[0034] When the activated carbon raw material needs to be processed into a spherical shape, first, the stirred activated carbon raw material and the binder are added to the interior of the outer shell 1 from the feeding port, and then the activated carbon raw material flows to the position of the extrusion mechanism 2 under the action of gravity, and the activated carbon raw material is processed into a spherical shape by the extrusion mechanism 2. Then, the spherical activated carbon moves downward to the interior of the solid mechanism 3 under the action of gravity, and the spherical activated carbon is further rounded by the solid mechanism 3, and the spherical activated carbon is dried at the same time to fix the shape of the spherical activated carbon, and then the spherical activated carbon flows out from the discharge port of the outer shell 1 under the action of gravity.

[0035] Continue reading Figure 1 and Figure 2The extrusion mechanism 2 includes a rotating cylinder 21 which is symmetrically arranged in the middle of the inner side of the outer shell 1, and a rotating assembly 25 is arranged on the outer shell 1. The rotating assembly 25 includes an extrusion roller 251 which is symmetrically arranged in the upper part of the inner side of the outer shell 1. A synchronous gear 252 is coaxially fixedly installed on the front side of the extrusion roller 251. The two synchronous gears 252 are meshed with each other. An execution motor 253 is fixedly installed on the right side of the upper part of the outer shell 1. The output shaft of the execution motor 253 is connected to the extrusion roller 251 on the right side through a belt, and the extrusion roller 251 is connected to the rotating cylinder 21 at the corresponding position through a belt.

[0036] After the activated carbon raw material is added into the interior of the outer shell 1, the execution motor 253 is started to drive the squeezing roller 251 on the right to rotate intermittently, and the squeezing roller 251 on the right drives the squeezing roller 251 on the left to rotate synchronously in the opposite direction through the synchronous gear 252, so that the two squeezing rollers 251 squeeze the activated carbon and transmit it downward, and at the same time, the squeezing roller 251 drives the two rotating drums 21 to rotate synchronously in the opposite direction, and the rotation linear speed of the squeezing roller 251 is equal to that of the rotating drum 21, so that the squeezing roller 251 and the rotating drum 21 can extrude the activated carbon raw material at the same speed to avoid the activated carbon raw material from breaking or piling up.

[0037] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The extrusion mechanism 2 also includes a plurality of groups of feed members 22 arranged on the cylindrical surface of the rotating cylinder 21 along the circumference thereof. Two adjacent groups of feed members 22 are arranged alternately front to back. Each group of feed members 22 is composed of feed members 22 arranged on the rotating cylinder 21 at equal intervals along the front-to-back direction. The feed members 22 are slidably connected to the rotating cylinder 21 along the radial direction. The end of the feed member 22 away from the axis of the rotating cylinder 21 is a hemispherical structure. A spherical mold 23 is fixedly installed inside the hemispherical structure of the feed member 22. Insert posts 24 are arranged at equal intervals along the spherical surface of the spherical mold 23. The insert posts 24 are slidably connected to the spherical mold 23 along the radial direction.

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The extrusion mechanism 2 also includes a moving assembly 26 commonly arranged on the two rotating cylinders 21, and the moving assembly 26 includes a fixed frame 261 rotatably arranged inside the rotating cylinder 21. The front and rear sides of the two fixed frames 261 are fixedly connected together by a connecting plate 265. An electric push rod 262 is fixedly installed on one side of the middle part of the fixed frame 261 close to the middle part of the outer shell 1, and a pushing plate 263 is fixedly installed at the telescopic section of the electric push rod 262. A limiting card seat 264 is evenly spaced along the front and rear direction on one side of the pushing plate 263 close to the middle part of the outer shell 1.

[0039] See also Figure 4 , Figure 5 and Figure 6 The extrusion mechanism 2 also includes a piercing assembly 27 arranged on the feed member 22. The piercing assembly 27 includes a piston rod 271 slidably arranged inside the feed member 22 along the length direction thereof. A push spring is arranged between the piston rod 271 and the feed member 22. The piston rod 271 has a circular plate structure on one side of the axis of the rotating cylinder 21 close to the corresponding position. An expansion air bag 272 for pushing the plug 24 is fixedly installed on the hemispherical structure of the feed member 22. A coil spring is arranged between the plug 24 and the spherical mold 23.

[0040] When the rotating cylinder 21 rotates, the rotating cylinder 21 drives the feed member 22 thereon to rotate synchronously, and the feed member 22 drives the piston rod 271 thereon to rotate synchronously. When a group of feed members 22 rotates to a horizontal position toward the middle of the outer shell 1, the feed member 22 drives the piston rod 271 thereon to move to the side of the push plate 263 close to the middle of the outer shell 1, and the circular plate structure of the piston rod 271 rotates to the inside of the limit clamp 264 at the corresponding position, so that the push plate 263 can push and pull the piston rod 271 through the limit clamp 264.

[0041] Then, the telescopic sections of the electric push rods 262 on both sides are extended at the same time, so that the electric push rods 262 drive a group of piston rods 271 at the corresponding position to move toward the middle of the outer shell 1 by pushing the plate 263, and the piston rods 271 drive the feed member 22 at the corresponding position to move synchronously through the push spring, and the feed member 22 drives the spherical mold 23 thereon to move synchronously, so that the spherical molds 23 on both sides extrude the activated carbon raw material. When the spherical molds 23 on both sides are moved to be combined together, the spherical molds 23 extrude the activated carbon raw material into the interior thereof and extrude the activated carbon raw material into a sphere.

[0042] In the initial state, the coil spring pushes the plug 24 by its own elastic force, so that the plug 24 is in a position away from the spherical shape of the spherical mold 23, thereby preventing the plug 24 from hindering the spherical mold 23 from molding and extruding the activated carbon raw material. When the spherical molds 23 on both sides are combined together, the telescopic section of the electric push rod 262 continues to extend, so that the piston rod 271 moves relative to the feed member 22 toward the middle of the outer shell 1, so that the piston rod 271 pushes the gas inside the feed member 22 toward the inside of the hemispherical structure above it, and then the expansion airbag 272 on the feed member 22 begins to expand.

[0043] The expanded airbag 272 pushes all the pins 24 on the same feed member 22 at the same time, so that the pins 24 are inserted into the interior of the spherical activated carbon inside the spherical mold 23, thereby piercing holes on the surface of the spherical activated carbon through the pins 24, thereby increasing the porosity of the spherical activated carbon and ensuring the adsorption effect of the spherical activated carbon.

[0044] See also Figure 6 and Figure 7 The extrusion mechanism 2 also includes a reinforcement component 28 arranged on the plug column 24, and the reinforcement component 28 includes an arc-shaped plate 281 arranged on it at equal intervals along the circumference of the plug column 24. The arc-shaped plate 281 is slidably connected with the plug column 24 along the radial direction. An inclined groove is provided on the side of the arc-shaped plate 281 close to the axis of the plug column 24. An active push member 282 is slidingly provided inside the plug column 24 along its length direction. A return spring is provided between the active push member 282 and the plug column 24. The active push member 282 slides in the inclined grooves of all the arc-shaped plate members 281 inside the same plug column 24 through the raised column thereon, and a fixing rod 283 is fixedly installed on the active push member 282.

[0045] When the plug 24 moves and is inserted into the interior of the spherical activated carbon, the plug 24 drives the active pusher 282 to move synchronously through the return spring. When the plug 24 is fully inserted into the interior of the spherical activated carbon, the active pusher 282 drives the fixed rod 283 thereon to press against the spherical mold 23, so that the spherical mold 23 pushes the active pusher 282 to move away from the center of the spherical mold 23 relative to the plug 24 through the reaction force on the fixed rod 283, thereby making the active pusher 282 drive the raised column thereon to move synchronously, and the raised column moves along the inclined groove of the arc plate 281, thereby making the active pusher 282 push the arc plate 281 thereon in the direction away from the axis of the plug 24, and the arc plate 281 presses and reinforces the pore wall on the spherical activated carbon to prevent it from shrinking.

[0046] Then, the telescopic section of the electric push rod 262 is retracted to make the plug 24 return to the initial position, and then the telescopic section of the electric push rod 262 is further retracted, so that the active push member 282 drives the spherical mold 23 to return to the initial position, and the spherical mold 23 drives the spherical activated carbon thereon to move synchronously to either side. Then, the rotating cylinder 21 is driven to rotate intermittently again by the execution motor 253, so that the spherical mold 23 drives the spherical activated carbon to rotate to the downward side.

[0047] See also Figure 1 , Figure 2 and Figure 8The extrusion mechanism 2 also includes a circulation component 29 arranged on the outer shell 1, and the circulation component 29 includes a diverter block 291 fixedly installed on the middle part of the inner side of the outer shell 1 symmetrically. The upper side of the diverter block 291 close to the rotating cylinder 21 is an arc-shaped surface structure. A flow pipe 292 is fixedly installed on the rear part of the outer shell 1. The lower part of the flow pipe 292 is an inclined surface gradually inclined from front to back, and the lower inclined surface of the flow pipe 292 is located at the lower side of the middle part of the two diverter blocks 291. The upper part of the flow pipe 292 is an inclined surface gradually inclined from back to front, and the upper inclined surface of the flow pipe 292 is located on the upper side of the feeding port at the upper part of the outer shell 1. The flow pipe 292 is provided with a lifting part 293 for lifting the activated carbon raw material, and the diverter block 291 is provided with a shearing part 294 for cutting the activated carbon raw material.

[0048] Continue reading Figure 1 , Figure 2 and Figure 8 The lifting part 293 includes a screw rod 2931 rotatably arranged inside the flow pipe 292, the outer side surface of the screw rod 2931 is attached to the inner wall of the flow pipe 292, the lower part of the screw rod 2931 is located on the lower side of the lower inclined surface of the flow pipe 292, and the upper part of the screw rod 2931 is located on the upper side of the upper inclined surface of the flow pipe 292. A power motor 2932 is fixedly installed on the upper part of the flow pipe 292, and the output shaft of the power motor 2932 is fixedly connected to the screw rod 2931.

[0049] See also Figure 1 and Figure 2 The shearing portion 294 includes a cutting knife 2941 which is slidably arranged on the right side diverter block 291, a hydraulic push rod 2942 is fixedly installed in the middle of the front side of the outer shell 1, and the telescopic section of the hydraulic push rod 2942 is fixedly connected to the cutting knife 2941. A notch is provided on the left side diverter block 291 at a position corresponding to the cutting knife 2941 for its insertion.

[0050] When the spherical activated carbon faces downward, it falls downward to the curved surface structure of the diverter block 291 under the action of its own weight, so that the spherical activated carbon is separated from the activated carbon raw material, and at the same time, the spherical activated carbon rolls downward along the curved surface structure of the diverter block 291. At the same time, the rotating cylinder 21 drives the remaining activated carbon raw material to move downward to the middle of the two diverter blocks 291. When the rotating cylinder 21 stops rotating, the telescopic section of the hydraulic push rod 2942 is extended to drive the cutting knife 2941 to move left to the inside of the notch of the diverter block 291 inserted on the left side, so that the cutting knife 2941 cuts off the activated carbon raw material.

[0051] The cut activated carbon raw material slides along the inclined surface at the bottom of the flow pipe 292 to the position of the screw rod 2931, and then the power motor 2932 is started to drive the screw rod 2931 to rotate continuously, so that the screw rod 2931 lifts the cut activated carbon raw material to the upper part of the flow pipe 292, and then the activated carbon raw material slides along the inclined surface at the upper part of the flow pipe 292 to the inside of the feeding port of the outer shell 1, so that the remaining activated carbon raw material can be reused.

[0052] See also Figure 1 , Figure 2 and Figure 8 The solid mechanism 3 includes a converging piece 31 fixedly mounted on the lower side of the outer shell 1. The converging piece 31 has a conical structure with a larger upper part and a smaller lower part. A funnel piece 32 is rotatably arranged at the lower part of the converging piece 31. A conduit 33 is rotatably arranged at the lower part of the funnel piece 32. The lower end of the conduit 33 extends into the discharge port of the outer shell 1. A rotating motor 34 is fixedly mounted on the lower front side of the outer shell 1. The output shaft of the rotating motor 34 is connected to the funnel piece 32 through a belt. A heating component 35 for drying the spherical activated carbon is arranged on the conduit 33.

[0053] Continue reading Figure 1 , Figure 2 and Figure 8 The heating component 35 includes air ducts 351 symmetrically arranged on both sides of the conduit 33. The air ducts 351 are fixedly connected and communicated with the conduit 33. The air ducts 351 are in a posture of gradually moving away from the conduit 33 from top to bottom. A hot air blower 352 is fixedly installed symmetrically on the lower part of the outer shell 1, and the hot air blower 352 is communicated with the air duct 351 at the corresponding position.

[0054] The spherical activated carbon moves downward from the diversion block 291 to the converging piece 31, and then converges through the conical surface on the inner side of the converging piece 31 and moves to the inside of the funnel piece 32. At the same time, the rotating motor 34 is started to drive the funnel piece 32 to rotate, so that the funnel piece 32 rolls the spherical activated carbon moved thereon, and at the same time, the spherical activated carbon moves to the middle part of the funnel piece 32 under the action of gravity. The hot air blower 352 is started to introduce hot air into the conduit 33 through the air duct 351, so that the hot air is blown upward along the conduit 33 to the inside of the funnel piece 32, and then the hot air dries the spherical activated carbon moved to the inside of the funnel piece 32, and then fixes the shape of the spherical activated carbon. The blowing from bottom to top can slow down the falling speed of the spherical activated carbon, and prevent the spherical activated carbon from falling and deforming.

[0055] When processing the activated carbon raw material into a spherical shape, the present invention also includes the following steps: the first step is to add the stirred activated carbon raw material and the adhesive into the interior of the outer shell 1 from the feeding port, and then start the execution motor 253 to drive the extrusion roller 251 and the rotating drum 21 to rotate at the same linear speed, so that the extrusion roller 251 and the rotating drum 21 can extrude the activated carbon raw material at the same speed to avoid the activated carbon raw material from breaking or piling up.

[0056] In the second step, the rotating cylinder 21 drives a group of feeding parts 22 to rotate to a horizontal position toward the middle of the outer shell 1, and at the same time, the electric push rods 262 extending from both sides drive the spherical molds 23 on both sides to move and combine together, so that the spherical molds 23 squeeze the activated carbon raw materials into the inside and squeeze the activated carbon raw materials into a sphere.

[0057] The third step is to continue to extend the telescopic section of the electric push rod 262, so that the piston rod 271 pushes all the pins 24 on the same feed member 22 through the inflatable airbag 272, so that the pins 24 are inserted into the interior of the spherical activated carbon inside the spherical mold 23, thereby piercing holes on the surface of the spherical activated carbon through the pins 24, thereby increasing the porosity of the spherical activated carbon and ensuring the adsorption effect of the spherical activated carbon.

[0058] In the fourth step, the spherical mold 23 pushes the active pusher 282 to move away from the center of the spherical mold 23 relative to the plug post 24 through the reaction force on the fixed rod 283, so that the active pusher 282 pushes the arc plate 281 thereon in the direction away from the axis of the plug post 24, and the arc plate 281 presses and reinforces the pore wall on the spherical activated carbon to prevent it from shrinking.

[0059] The fifth step is to retract the telescopic section of the electric push rod 262 to return the plug column 24 to its initial position, and then continue to retract the telescopic section of the electric push rod 262 so that the active push member 282 drives the spherical mold 23 to return to its initial position, and the spherical mold 23 drives the spherical activated carbon thereon to move synchronously to either side, and then the execution motor 253 drives the rotating cylinder 21 to rotate intermittently again, so that the spherical mold 23 drives the spherical activated carbon to rotate to the lower side.

[0060] In the sixth step, the spherical activated carbon rolls downward along the curved structure of the diverter block 291 under the action of its own weight, and at the same time, the rotating cylinder 21 drives the remaining activated carbon raw materials to move downward to the middle of the two diverter blocks 291. When the rotating cylinder 21 stops rotating, the telescopic section of the hydraulic push rod 2942 is extended to drive the cutting knife 2941 to move left to the inside of the notch of the diverter block 291 inserted on the left side, so that the cutting knife 2941 cuts off the activated carbon raw materials.

[0061] In the seventh step, the cut activated carbon raw material slides along the inclined surface at the bottom of the flow pipe 292 to the position of the screw rod 2931, and then the power motor 2932 is started to drive the screw rod 2931 to rotate continuously, so that the screw rod 2931 lifts the cut activated carbon raw material to the upper part of the flow pipe 292, and then the activated carbon raw material slides along the inclined surface at the upper part of the flow pipe 292 to the inside of the feeding port of the outer shell 1, so as to reuse the remaining activated carbon raw material.

[0062] The eighth step is to start the rotating motor 34 to drive the funnel piece 32 to rotate, so that the funnel piece 32 rolls the spherical activated carbon moved thereon, and at the same time start the hot air blower 352 to introduce hot air into the conduit 33 through the air duct 351, so that the hot air dries the spherical activated carbon moved to the inside of the funnel piece 32, thereby fixing the shape of the spherical activated carbon, and by blowing from bottom to top, the falling speed of the spherical activated carbon can be slowed down to prevent the spherical activated carbon from falling and deforming.
