Description

Technical Field

[0001] The invention relates to the technical field of activated carbon powder regeneration, and in particular to a method and device for regenerating waste activated carbon powder. Background Art

[0002] Activated carbon is widely used in the purification of gaseous and liquid flows due to its huge specific surface area, developed pore structure and strong adsorption capacity. Powdered activated carbon has a fast filtration speed and strong decolorization and deodorization ability. It has been widely used in medicine, food, lithium batteries and printing and dyeing wastewater decolorization. However, after the adsorption saturated activated carbon is replaced by fresh activated carbon, it is often landfilled or incinerated, causing economic waste and environmental pollution.

[0003] Patent application CN217221512U discloses a powdered activated carbon regeneration device, including a heating box, a conveyor belt, a combustion furnace and a gas pipeline. A loading box is provided on the conveyor belt, a ventilation cover is provided on the upper side of the loading box, an air inlet cylinder is provided on one side of the loading box, the air inlet of the air inlet cylinder faces downward, a plurality of groups of air guide pipes are provided at the air outlet of the air inlet cylinder, and air diffusion holes are provided on the lower surface of the air guide pipe. The powdered activated carbon regeneration device is provided with an air inlet cylinder on the loading box, hot air enters the air guide pipe along the air inlet cylinder, and passes into the center of the loading box through the air diffusion holes, so that the hot air is in full contact with the activated carbon powder in the loading box, and the inner layer of powdered activated carbon is fully dried, with high processing efficiency and low energy consumption.

[0004] However, the device still has some shortcomings: the device facilitates the full contact and drying of activated carbon powder with hot air, but in the process of processing waste powdered activated carbon, the material humidity will be relatively high, resulting in a decrease in density of the activated carbon powder after absorbing moisture, resulting in a smaller specific gravity of the dried material. At the same time, the activated carbon powder has a high humidity, which increases its own viscosity and easily adheres to the inner wall of the mixing component, causing resource loss.

At the same time, when the electric rotating rod rotates, it drives the filter plate to rotate, and the filter plate rotates and swings the material falling on the top of itself through the centrifugal force of rotation. At the same time, the electric rotating rod also drives the special-shaped plate to revolve, and the special-shaped plate stirs the material and the composite binder inside the mixing component when it revolves; when the special-shaped plate rotates, it drives the guide rod to rotate, and the guide rod contacts and guides the material through the circular surface, and when the special-shaped plate revolves, it drives the I-shaped column to revolve, and the I-shaped column contacts and rubs with the inner wall of the mixing component during the revolution and generates a rotation force, and when the I-shaped column rotates inside the special-shaped plate, it drives the elastic scraper to rotate and scrape the inner wall of the mixing component, and when the elastic scraper is deformed by the material resistance, the limit ring limits the elastic scraper.

[0017] According to the above technical scheme, the anti-accumulation device also includes a semicircular hollow plate, a square frame, a plurality of drying round blocks and a penetrating rod. The back side of the semicircular hollow plate is slidably mounted on the front side of the outer wall of the special-shaped plate. The semicircular hollow plate is located on the arc surface movement trajectory of the resistance plate. The back side of the square frame is slidably mounted on the front side of the special-shaped plate through a longitudinal spring.

The bottom of the drying round block contacts the top of the square frame. The outer wall of the penetrating rod is penetrated and fixedly mounted inside the drying round block. When the resistance plate slides horizontally toward the inner wall of the mixing component, it contacts the arc surface of the outer wall of the semicircular hollow plate.

When the cylinder is reset, the inclined plate is reset synchronously through the torsion spring, and this process repeats.

[0021] The present invention provides a method and device for regenerating waste activated carbon powder. It has the following beneficial effects:

[0022] (1) The present invention, through the setting of the anti-loss device, cooperates with the electric rotating rod, the transmission ring, the transmission plate, the heating component, the filter plate, the special-shaped plate, the guide rod, the I-beam column, the elastic scraper and the limit ring to expand the range of the heating component, thereby accelerating the overall heating speed inside the mixing component, preliminarily drying the material to reduce its viscosity, and preventing the material from having a high humidity and causing a density reduction phenomenon. At the same time, the material is facilitated to disperse and fall, and the rotation disturbance of the special-shaped plate is relied on to accelerate the uniformity of mixing the material and the binder and facilitate subsequent granulation molding; and the bonding effect between the material and the binder is further enhanced by the guiding effect of the guide rod. At the same time, the limit ring prompts the elastic scraper to always be close to the inner wall of the mixing component, preventing the activated carbon powder from adhering to the inner wall of the mixing component due to its own high humidity, and avoiding the material from being difficult to adhere to the composite binder due to adhesion and remaining inside the mixing component to cause resource loss.

[0023] (2) The present invention sets an anti-accumulation device, and cooperates with a special-shaped plate, a friction wheel, a reciprocating screw, a material dividing plate, a resistance plate, a semicircular hollow plate, a square frame, a drying block and a through rod. The material dividing plate is used to make the material accumulated on the bottom of the inner wall of the mixing component revolve and push it horizontally, so that the material is more evenly dispersed and spread at the bottom of the inner wall of the mixing component, preventing the material from being difficult to remove moisture due to accumulation and accumulation, and avoiding poor bonding between the material and the binder, thereby affecting the subsequent granulation effect; at the same time, the reciprocating sliding of the drying block is used to scrape off the residual material on the outer wall of the guide rod and increase the force to disturb the material upward. At the same time, the built-in desiccant of the drying block ensures that it is always in a dry state. At this time, during the reciprocating sliding of the drying block, water vapor can be effectively avoided from remaining on the outer wall of the guide rod, and the adhesion of the guide rod to the material can be further prevented from increasing during the revolution of the guide rod, ensuring that the material and the binder can be fully utilized to reduce material waste.

[0024] (3) The present invention, through the setting of the anti-interference device, cooperates with the square frame, the fixed plate, the hollow shell, the sliding baffle, the L-shaped rod, the groove block, the cylinder and the inclined plate, so as to promote the material to continuously change the circulation speed inside the mixing component, so that the material is dispersed more thoroughly and the fusion effect with the binder is better. At the same time, when the circulation speed is slowed down, the contact time between the material and the drying block is prolonged, so that the drying block itself emits dry gas in the process of reciprocating up and down movement to further expand the coverage of the inside of the material, shorten the time required for the material to evaporate water, and avoid a small amount of residual water from interfering with the subsequent process; at the same time, the material falling to the top of the filter plate is guided by the inclined surface of the inclined plate, so as to reduce the impact force between the material and the filter plate, avoid the fragmentation of some materials containing water under the impact, thereby reducing the integrity of the material and making the regeneration process of the activated carbon more difficult, and at the same time reduce the amount of dust generated when the material falls to avoid loss, and prevent dust from floating around and attaching to increase the difficulty of subsequent maintenance.

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] See also Figure 1-Figure 7 One embodiment of the present invention is: a method for regenerating waste activated carbon powder, comprising the following steps:

[0035] S1: preparing a composite binder: premixing a plant-based organic binder, an organic rubber powder and a surfactant, wherein the plant-based organic binder comprises at least one of sodium carboxymethyl cellulose, sodium hydroxymethyl cellulose, guar gum, glucose, fructose, xanthan gum, sesbania gum, modified starch and glutinous rice flour;

[0040] An anti-loss device 4 is provided inside the mixing assembly 32, an anti-accumulation device 5 is provided at the bottom of the anti-loss device 4, and an anti-interference device 6 is provided above the anti-accumulation device 5;

[0041] The anti-loss device 4 includes an electric rotating rod 41, the top of the electric rotating rod 41 is rotatably installed on the top of the inner wall of the mixing component 32, a reciprocating spiral groove is opened on the outer wall of the top of the electric rotating rod 41, and a transmission ring 42 is movably installed on the outer wall of the reciprocating spiral groove of the electric rotating rod 41, and a plurality of transmission plates 43 are equidistantly and fixedly installed on the outer wall of the transmission ring 42, a heating component 44 is fixedly installed on one end of the transmission plate 43 close to the inner wall of the mixing component 32, and the outer wall of the heating component 44 is slidably installed on the inner wall of the mixing component 32, a filter plate 45 is fixedly installed on the outer wall of the middle end of the electric rotating rod 41, and a plurality of special-shaped plates 46 are fixedly installed on the outer wall of the bottom end of the electric rotating rod 41, and the plurality of special-shaped plates 46 are equidistantly distributed on the outer wall of the electric rotating rod 41, and a plurality of guide rods 47 are equidistantly and fixedly installed inside the special-shaped plate 46, an I-shaped column 48 is rotatably installed inside the end of the special-shaped plate 46 close to the inner wall of the mixing component 32, and the inner wall of the I-shaped column 48, etc. A plurality of elastic scraping strips 49 are fixedly installed at a distance, and a limiting ring 410 is fixedly installed on the outer wall of the middle end of the I-beam column 48. Through the above cooperation, the activity range of the heating component 44 is expanded to accelerate the overall heating speed inside the mixing component 32, and the material is preliminarily dried to reduce its viscosity, so as to prevent the material from having a high humidity and causing a density reduction. At the same time, the material is facilitated to disperse and fall, and the rotation disturbance of the special-shaped plate 46 is relied on to accelerate the uniformity of mixing the material and the binder and facilitate subsequent granulation molding; through the above cooperation, the bonding effect between the material and the binder is further enhanced with the help of the guiding effect of the guide rod 47, and at the same time, the limiting ring 410 prompts the elastic scraping strip 49 to always be close to the inner wall of the mixing component 32, so as to prevent the activated carbon powder from adhering to the inner wall of the mixing component 32 due to its own high humidity, and to avoid the material from being difficult to adhere to the composite binder due to adhesion and thus remaining inside the mixing component 32 to cause resource loss.

[0042] The outer wall of the filter plate 45 contacts the inner wall of the mixing assembly 32 , a U-shaped groove is provided at the bottom of the special-shaped plate 46 , the outer wall of the I-shaped column 48 contacts the inner wall of the mixing assembly 32 , and the outer wall of the limiting ring 410 contacts the concave surface of the elastic scraper strip 49 .

[0043] When in use, the waste activated carbon powder is introduced into the mixing component 32 through the conveying pipe at the left end of the mixing component 32, and then the premixed composite binder and process water are added into the mixing component 32 from the two pipes at the top of the mixing component 32, and the material is mixed and bonded with the composite binder, and then the granulation work is carried out through the primary granulation component 2 and the secondary granulation component 21. After the granulation is completed, the material is conveyed to the drying component 22 through the connecting pipe 23 for drying, carbonization and cooling treatment, and finally the material enters the screening component 3 for screening, and the dust generated when the material is screened is introduced into the mixing component 32 through the conveying component 31 to avoid waste;

[0044] Before the material enters the mixing component 32, the electric rotating rod 41 is started. When the electric rotating rod 41 rotates, the reciprocating spiral groove on its outer wall restricts the built-in block of the transmission ring 42, so that when the electric rotating rod 41 rotates, the transmission ring 42 can slide upward along the outer wall of its reciprocating spiral groove and reset, and the transmission ring 42 drives the transmission plate 43 to move synchronously, and the transmission plate 43 drives the heating component 44 to slide upward and reset along the inner wall of the mixing component 32. At the same time, when the electric rotating rod 41 rotates, it drives the filter plate 45 to rotate. The filter plate 45 rotates and swings the material that falls on the top of itself through the centrifugal force of rotation. At the same time, the electric rotating rod 41 also drives the special-shaped plate 46 to revolve. When the special-shaped plate 46 revolves, it stirs the material and the composite binder inside the mixing component 32. Through the above cooperation, the activity range of the heating component 44 is expanded, thereby accelerating the overall heating speed inside the mixing component 32, preliminarily drying the material to reduce its viscosity, and preventing the material from having a large humidity and a density reduction phenomenon. At the same time, the material is dispersed and falls conveniently and in accordance with The rotation disturbance of the special-shaped plate 46 accelerates the uniformity of mixing the material and the binder and facilitates the subsequent granulation molding; when the special-shaped plate 46 rotates, it drives the guide rod 47 to rotate, and the guide rod 47 contacts and guides the material through the circular surface. When the special-shaped plate 46 revolves, it drives the I-shaped column 48 to revolve. During the revolution, the I-shaped column 48 contacts and rubs with the inner wall of the mixing component 32 and generates a rotation force. When the I-shaped column 48 rotates inside the special-shaped plate 46, it drives the elastic scraper 49 to rotate and scrape the inner wall of the mixing component 32. At the same time, when the elastic scraper When 49 is subjected to the force of deformation caused by the resistance of the material, the limiting ring 410 limits the elastic scraper 49. Through the above cooperation, the bonding effect between the material and the binder is further improved with the help of the guiding effect of the guide rod 47. At the same time, the limiting ring 410 prompts the elastic scraper 49 to always be close to the inner wall of the mixing component 32, preventing the activated carbon powder from adhering to the inner wall of the mixing component 32 due to its own high humidity, and preventing the material from being difficult to adhere to the composite binder due to adhesion and remaining inside the mixing component 32 to cause resource loss.

[0045] See also Figure 1-Figure 7 , based on the above embodiment, another embodiment of the present invention further includes an anti-accumulation device 5;

[0046] The anti-accumulation device 5 includes a plurality of friction wheels 51, a reciprocating screw 52, ​​a plurality of dividing plates 53 and a contact plate 54. The plurality of friction wheels 51 are symmetrically and rotatably mounted on the inner wall of the U-shaped groove of the special-shaped plate 46. Both ends of the reciprocating screw 52 are fixedly mounted on the center of the friction wheel 51 close to the axis of the special-shaped plate 46. The plurality of dividing plates 53 penetrate through the inside and are movably mounted on the outer wall of the reciprocating screw 52. The bottom of the contact plate 54 is fixedly mounted on the top of the dividing plate 53. Through the above coordination, the dividing plate 53 is used to orbit and horizontally push the material accumulated at the bottom of the inner wall of the mixing component 32, so that the material is more evenly dispersed and spread at the bottom of the inner wall of the mixing component 32, thereby preventing the material from being difficult to heat due to aggregation and accumulation, resulting in difficulty in removing moisture, and avoiding poor bonding between the material and the binder, thereby affecting the later granulation effect.

[0047] The outer wall of the friction wheel 51 contacts the bottom of the inner wall of the mixing assembly 32 , the top inner wall of the dividing plate 53 is slidably mounted on the outer wall of the special-shaped plate 46 , and the bottom of the dividing plate 53 contacts the bottom of the inner wall of the mixing assembly 32 .

[0048] The anti-accumulation device 5 also includes a semicircular hollow plate 55, a square frame 56, a plurality of drying round blocks 57 and a through rod 58. The back of the semicircular hollow plate 55 is slidably mounted on the front of the outer wall of the special-shaped plate 46. The semicircular hollow plate 55 is located on the arc motion trajectory of the resistance plate 54. The back of the square frame 56 is slidably mounted on the front of the special-shaped plate 46 through a longitudinal spring. The bottom of the square frame 56 is fixedly connected to the top of the semicircular hollow plate 55. The plurality of drying round blocks 57 penetrate inside and are slidably mounted on the outer wall of the guide rod 47. The drying round blocks 57 have desiccants built in them. The bottom of the drying round blocks 57 is connected to the square frame 58. 56 contacts the top, and the outer wall of the penetrating rod 58 penetrates and is fixedly installed inside the drying round block 57. Through the above cooperation, the drying round block 57 slides back and forth to scrape off the residual material on the outer wall of the guide rod 47 and increase the force of disturbing the material upward. At the same time, the built-in desiccant of the drying round block 57 ensures that it is always in a dry state. At this time, during the reciprocating sliding of the drying round block 57, it is effectively prevented that the outer wall of the guide rod 47 has residual water vapor, and further prevents the guide rod 47 from increasing its adhesion to the material during its revolution, ensuring that the material and the adhesive can be fully utilized to reduce material waste.

[0049] When in use, the special-shaped plate 46 drives the friction wheel 51 to revolve along the bottom of the inner wall of the mixing component 32 when it revolves, generating friction force. The friction wheel 51 rotates along the inner wall of the U-shaped groove of the special-shaped plate 46 by the friction force. When the friction wheel 51 rotates, it drives the reciprocating screw rod 52 to rotate. When the reciprocating screw rod 52 rotates, the reciprocating spiral groove on its outer wall restricts the built-in block of the dividing plate 53, so that the dividing plate 53 can slide and reset on the outer wall of the reciprocating screw rod 52 toward the inner wall of the mixing component 32, and the dividing plate 53 drives the contact plate 54 to move synchronously. The restriction of the contact plate 54 on several dividing plates 53 causes multiple dividing plates 53 to move synchronously. Through the above cooperation, the dividing plate 53 is used to revolve and horizontally push the materials accumulated at the bottom of the inner wall of the mixing component 32, so that the materials are more evenly dispersed and spread at the bottom of the inner wall of the mixing component 32, preventing the materials from being difficult to heat due to aggregation and accumulation, resulting in difficulty in removing moisture, and avoiding poor bonding between the materials and the binder, thereby affecting the later granulation effect; the contact plate When 54 slides horizontally toward the inner wall of the mixing component 32, it contacts the arc surface of the outer wall of the semicircular hollow plate 55. The arc surface guides the semicircular hollow plate 55 to push the square frame 56 to slide upward along the outer wall of the special-shaped plate 46. When the contact plate 54 is reset, the square frame 56 is reset by the spring force and drives the semicircular hollow plate 55 to reset. The square frame 56 pushes the drying block 57 to slide upward along the outer wall of the guide rod 47. The restriction of the drying block 57 by the penetrating rod 58 causes multiple drying blocks 57 to slide synchronously. Through the above cooperation, the reciprocating sliding of the drying block 57 scrapes off the residual material on the outer wall of the guide rod 47 and increases the force of disturbing the material upward. At the same time, the built-in desiccant of the drying block 57 ensures that it is always in a dry state. At this time, in the process of reciprocating sliding of the drying block 57, it is effectively avoided that there is residual water vapor on the outer wall of the guide rod 47, and further prevents the adhesion of the guide rod 47 to the material during the revolution, so as to ensure that the material and the adhesive can be fully utilized and reduce material waste.

[0050] See also Figure 1-Figure 7 , based on the above embodiment, another embodiment of the present invention further includes an anti-interference device 6;

[0051] The anti-interference device 6 includes a fixed plate 61, a hollow shell 62, a sliding baffle 63 and an L-shaped rod 64. The back of the fixed plate 61 is fixedly mounted on the front of the outer wall of the top of the special-shaped plate 46, the top of the hollow shell 62 is fixedly mounted on the bottom of the fixed plate 61, the outer wall of the sliding baffle 63 penetrates and is slidably mounted inside the hollow shell 62, and the top of the L-shaped rod 64 is fixedly mounted on the outer wall of the sliding baffle 63 near the axis of the special-shaped plate 46. Through the above cooperation, the material is prompted to continuously change the circulation speed inside the mixing component 32, so that the material is dispersed more thoroughly and the fusion effect with the binder is better. At the same time, when the circulation speed is slowed down, the contact time between the material and the drying block 57 is extended, so that the drying block 57 is prompted to emit dry gas in the process of reciprocating up and down movement. Further expand the coverage of the inside of the material, shorten the time required for the material to evaporate water, and avoid a small amount of residual water from interfering with the subsequent process.

[0052] The top of the sliding baffle 63 actively penetrates the interior of the filter plate 45 , and the bottom of the L-shaped rod 64 is fixedly installed on the outer wall of the square frame 56 near one side of the axis of the special-shaped plate 46 .

[0053] The anti-interference device 6 also includes a groove block 65, a cylinder 66 and an inclined plate 67. The bottom of the groove block 65 is fixedly installed on the top of the sliding baffle 63, the outer wall of the cylinder 66 is fixedly installed inside the groove block 65, the top of the inclined plate 67 is hinged at the outer wall of the cylinder 66, and the bottom of the inclined plate 67 is slidably installed on the top of the filter plate 45. Through the above cooperation, the material falling to the top of the filter plate 45 is guided by the inclined surface of the inclined plate 67, thereby reducing the impact force between the material and the filter plate 45, avoiding the fragmentation of some materials containing water under the impact, thereby reducing the integrity of the material and making the regeneration process of the activated carbon more difficult, and at the same time reducing the amount of dust generated when the material falls to avoid loss, and preventing dust from floating around and attaching to increase the difficulty of later maintenance.

[0054] When in use, the square frame 56 slides upward and resets, driving the L-shaped rod 64 to move synchronously. The L-shaped rod 64 drives the sliding baffle 63 to slide synchronously along the inner wall of the hollow shell 62, and the fixed plate 61 limits and stabilizes the hollow shell 62. At this time, the sliding baffle 63 gradually reduces the shielding area of ​​the guide rod 47 in the special-shaped plate 46 by itself and the hollow shell 62 during the upward sliding process, that is, the time and amount of the material passing through the special-shaped plate 46 are constantly changing. Through the above cooperation, the material is prompted to continuously change the circulation speed inside the mixing component 32, so that the material is dispersed more thoroughly and the fusion effect with the binder is better. At the same time, when the circulation speed is slowed down, the contact time between the material and the drying round block 57 is extended, so that the drying round block 57 is prompted to emit dry gas in the process of reciprocating up and down movement. Further expand the coverage of the inside of the material, shorten the time required for the material to evaporate water, and avoid A small amount of residual moisture interferes with the subsequent process; the sliding baffle 63 drives the groove block 65 to move synchronously during the reciprocating up and down movement, and the groove block 65 drives the cylinder 66 to move reciprocating up and down. When the cylinder 66 moves upward, it drives the inclined plate 67 to move synchronously. At this time, the hinge axis of the inclined plate 67 begins to rotate, and under the pull of the cylinder 66, the inclined plate 67 is forced to flip upward with its own hinge axis as the axis. When the cylinder 66 is reset, the inclined plate 67 is reset synchronously by the torsion spring, and this is repeated repeatedly. Through the above cooperation, the material falling to the top of the filter plate 45 is guided by the inclined surface of the inclined plate 67, thereby reducing the impact force between the material and the filter plate 45, avoiding the fragmentation of some materials containing water under the impact, thereby reducing the integrity of the material, making the regeneration process of the activated carbon more difficult, and at the same time reducing the amount of dust generated when the material falls to avoid loss, and preventing dust from floating around and attaching to increase the difficulty of later maintenance.
