Description

Technical Field

[0001] The present invention relates to the technical field of activation devices, and more specifically, to an activation device and a method for preparing activated carbon for spontaneously circulating formaldehyde filtration. Background Art

[0002] Activated carbon is a specially treated carbon. Organic raw materials such as fruit shells, coal, and wood are heated in an airtight environment to reduce non-carbon components. This process is called carbonization. After that, it reacts with gas, and the surface is corroded to produce a structure with developed micropores. This process is called activation. Since the activation process is a microscopic process, that is, the surface corrosion of a large number of molecular carbides is point corrosion, the surface of the activated carbon has countless tiny pores. When preparing activated carbon, an activated carbon preparation activation method is required.

[0003] Among them, the patent with announcement number CN219603263U discloses an activated carbon preparation and activation device, including a preparation cylinder, a feed port is provided on the upper surface of the preparation cylinder, a dust cover is provided on the outside of the feed port, a steam box is symmetrically provided on the outside of the preparation cylinder, the outsides of the two steam boxes are connected with air inlet pipes, the air inlet ends of the two air inlet pipes are provided with sealing covers, the upper surfaces of the two steam boxes are fixedly connected with air pumps, the air inlet ends of the two air pumps are connected to the inside of the steam box through pipelines, and the air outlet ends of the two air pumps are connected to the inside of the preparation cylinder through pipelines;

[0004] When the structure is in use, through the set air pump, steam box and air inlet pipe, when the raw materials need to be activated, the raw materials only need to be placed in the preparation cylinder first, and the heater starts to run at this time to bake the raw materials in the preparation cylinder. While the heater is running, the staff can open the sealing cover and add steam to the steam box through the air inlet pipe. At this time, the air pump starts to run and transmits the steam in the steam box to the inside of the preparation cylinder through the pipeline. At this time, the organic raw materials can be fully activated, so that the prepared activated carbon has better adsorption capacity. However, when the structure is in use, it is not easy for the steam and the heat during heating to fully contact with the activated carbon, and the function of wrapping and activating the activated carbon by the steam and the heat during heating cannot be realized, resulting in a poor activation effect.

[0009] Optionally, in a possible embodiment, the outer side of the lower pressure cylinder is threadedly connected with an inner thread ring, the inner thread ring is located at the top of the activation furnace, the inner thread ring is rotatably connected to the activation furnace, a plurality of L rods are distributed in the middle part of the first conduit, and a diverter plate is arranged on the top of each L rod, the diverter plate is located on the outer side of the pad, the pad is rotatably connected to the diverter plate, a reinforcement frame is installed on the outer side of the activation furnace by bolts, the reinforcement frame is hinged to the base, a first electric push rod is installed on the bottom of the base by bolts, a slider is provided at the output end of the first electric push rod, the slider is slidably connected to the base, a second electric push rod is hinged on the slider, the output end of the second electric push rod extends to the reinforcement frame and is hinged to the reinforcement frame, and a door panel is hinged on the outer side of the activation furnace;

[0010] A preparation method, using the above-mentioned spontaneous circulation formaldehyde filtering activated carbon preparation activation device, is characterized by comprising the following steps:

[0011] Step 1: The staff installs the device at the designated location. When preparing and activating the activated carbon, the staff opens the door panel, places the activated carbon on the pad, supports the activated carbon with the support block, and then closes the door panel. By rotating the inner wire ring, the lower pressure cylinder can drive the drive motor, exhaust pipe, temperature sensor, shaft and slide rod to move downward, so that the pressure plate and limit plate can press against the top of the activated carbon.

[0012] Step 2: The activator is atomized by the atomizer and transported to the first conduit through the second conduit. The atomized activator is discharged through each diversion hole. The atomized activator is dispersed in the form of tiny droplets or aerosols, which can evenly cover the surface of the activated carbon particles, and is diverted through each diversion plate to avoid excessively high or low local concentrations.

[0013] Step 3: At the same time, the driving motor is started, and the output end of the driving motor drives the rotating shaft, the sliding rod, the spring, the pressing plate and the limiting plate to rotate, thereby rotating the activated carbon, so that the activating agent is evenly distributed, which helps to form more regular pores, micropores and mesopores in the carbon structure, and improves the adsorption capacity of the activated carbon. At the same time, when the pressing plate is pressed against the activated carbon, the spring is compressed to ensure that the pressing plate and the limiting plate can be stuck on the activated carbon, which is easy for the activated carbon to rotate;

[0014] Step 4: When the lower pressing cylinder moves downward, it can also drive the support ring to move downward, and then each heating rod moves downward synchronously, and the activator is heated by the heat conduction wire, so that the droplets are quickly vaporized at high temperature, so that they can quickly penetrate into the carbon particles at high temperature, evenly etch the pores, and avoid local over-activation or under-activation;

[0015] Step 5, the bottom end of the heating rod can contact the insulating cone, and the heating rod can rotate along the axis point of the connection between the heating rod and the support ring through the shape of the insulating cone, so that each heating rod can be tilted and gathered on the outside of the activated carbon, which is convenient for the activator to directly act on the deep pores of the carbon material and reduce heat energy waste;

[0016] Step six. When in use, the first electric push rod drives the slider to move, which in turn causes the second electric push rod to move. The second electric push rod drives the reinforcement frame to rotate along the axis point of the connection between the reinforcement frame and the base, so that the activation furnace can deflect on the base. After the activating agent that is easy to atomize is sprayed out through the first conduit and the diversion hole, it reciprocates through the output end of the second electric push rod to achieve the function of shaking the activation furnace. The activating agent that is easy to atomize wraps the activated carbon to ensure the activation effect of the activated carbon.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention atomizes the activator through an atomizer and transports it to the first duct through the second duct. The atomized activator is discharged through each diversion hole. The atomized activator is dispersed in the form of tiny droplets or aerosols, which can evenly cover the surface of the activated carbon particles, and is diverted through each diversion plate to avoid excessively high or low local concentrations.

[0019] 2. The activated carbon of the present invention can be rotated to make the activator evenly distributed, which helps to form more regular pores in the carbon structure and improve the adsorption capacity of the activated carbon. At the same time, when the pressing plate is pressed against the activated carbon, the spring is compressed to ensure that the pressing plate and the limit plate can be stuck on the activated carbon, making it easy for the activated carbon to rotate;

[0020] 3. When the lower pressing cylinder of the present invention moves downward, it can also drive the support ring to move downward, and then each heating rod moves downward synchronously, and the activator is heated by the heat conduction wire, so that the droplets are quickly vaporized at high temperature, so that it can quickly penetrate into the interior of the carbon particles at high temperature, evenly etch the pores, and avoid local over-activation or insufficient activation;

[0021] 4. The heating rod of the present invention can rotate along the axis point of the connection between the heating rod and the support ring through the shape of the insulating cone, so that each heating rod can be tilted and gathered outside the activated carbon, which is convenient for the activator to directly act on the deep pores of the carbon material and reduce heat energy waste;

[0022] 5. The present invention drives the slider to move through the first electric push rod, which in turn causes the second electric push rod to move, and the second electric push rod drives the reinforcing frame to rotate along the axis point where the reinforcing frame and the base are connected, so that the activation furnace can deflect on the base, and the activating agent that is easy to atomize is sprayed out through the first conduit and the diversion hole, and then reciprocates through the output end of the second electric push rod, so as to realize the function of shaking the activation furnace, and the activating agent that is easy to atomize wraps the activated carbon, thereby ensuring the activation effect of the activated carbon;

[0023] To sum up, through the corresponding coordinated use of various structures, the atomized activator is dispersed in the form of tiny droplets or aerosols, which can evenly cover the surface of the activated carbon particles, and is diverted through various diversion plates to avoid local concentrations that are too high or too low. The heating rods are synchronously displaced downward, and the activator is heated by the heat conduction wire, so that the droplets are quickly vaporized at high temperatures, so that it can quickly penetrate into the interior of the carbon particles at high temperatures, evenly etching the pores to avoid local over-activation or under-activation. The heating rods can be tilted and gathered on the outside of the activated carbon, which is convenient for the activator to directly act on the deep pores of the carbon material and reduce heat energy waste. The activation furnace can deflect on the base, and the easily atomized activator is sprayed out through the first conduit and the diversion hole, and then reciprocates through the output end of the second electric push rod to realize the function of shaking the activation furnace, and the easily atomized activator wraps the activated carbon to ensure the activated carbon activation effect.

[0038] A preparation method, using the above-mentioned activated carbon preparation activation device for spontaneously circulating formaldehyde filtration, comprises the following steps:

[0039] Step 1: The staff installs the device at the designated position. When preparing and activating the activated carbon, the staff opens the door panel 30, places the activated carbon on the pad 5, supports the activated carbon through the support block 6, and then closes the door panel 30. By rotating the inner wire ring 23, the lower pressure cylinder 10 can drive the driving motor 21, the exhaust pipe 22, the temperature sensor 20, the rotating shaft 15 and the sliding rod 16 to move downward, so that the pressing plate 18 and the limiting plate 19 can press against the top of the activated carbon.

[0040] Step 2: The activator is atomized by the atomizer 7 and transported to the first duct 3 through the second conduit 8. The atomized activator is discharged through each diversion hole 4. The atomized activator is dispersed in the form of tiny droplets or aerosols, which can evenly cover the surface of the activated carbon particles, and is diverted by each diversion plate 25 to avoid excessively high or low local concentrations.

[0041] Step 3: At the same time, the drive motor 21 is started, and the output end of the drive motor 21 drives the rotating shaft 15, the slide bar 16, the spring 17, the pressing plate 18 and the limiting plate 19 to rotate, thereby rotating the activated carbon, so that the activating agent is evenly distributed, which helps to form more regular pores, micropores and mesopores in the carbon structure, and improve the adsorption capacity of the activated carbon. At the same time, when the pressing plate 18 is pressed against the activated carbon, the spring 17 is compressed to ensure that the pressing plate 18 and the limiting plate 19 can be stuck on the activated carbon, which is easy for the activated carbon to rotate;

[0042] Step 4: When the lower pressing cylinder 10 moves downward, the supporting ring 11 can also be driven to move downward, and then each heating rod 13 is synchronously moved downward, and the activator is heated by the heat conducting wire 14, so that the droplets are quickly vaporized at high temperature, so that the droplets can quickly penetrate into the carbon particles at high temperature, and the pores are evenly etched to avoid local over-activation or under-activation;

[0043] Step 5, the bottom end of the heating rod 13 can contact the insulating cone 9, and the heating rod 13 can rotate along the axis point of the connection between the heating rod 13 and the support ring 11 through the shape of the insulating cone 9, so that each heating rod 13 can be tilted and gathered on the outside of the activated carbon, which is convenient for the activator to directly act on the deep pores of the carbon material and reduce the waste of heat energy;

[0044] Step six, when in use, the first electric push rod 27 drives the slider 28 to move, and then the second electric push rod 29 is moved, and the second electric push rod 29 drives the reinforcing frame 26 to rotate along the axis point of the connection between the reinforcing frame 26 and the base 1, so that the activation furnace 2 can deflect on the base 1, and the activating agent that is easy to atomize is sprayed out through the first conduit 3 and the diversion hole 4, and then reciprocates through the output end of the second electric push rod 29, so as to realize the function of shaking the activation furnace 2, and the activating agent that is easy to atomize wraps the activated carbon, thereby ensuring the activation effect of the activated carbon.

[0045] According to the above structure, when in use, the activated carbon is placed on the pad 5, supported by the support block 6, and then the door panel 30 is closed. By rotating the inner wire ring 23, the lower pressure cylinder 10 can drive the driving motor 21, the exhaust pipe 22, the temperature sensor 20, the rotating shaft 15 and the sliding rod 16 to move downward, and then the pressing plate 18 and the limiting plate 19 can be pressed against the top of the activated carbon, and the activator is atomized by the atomizer 7 and transported to the first conduit 3 through the second conduit 8. The atomized activator is discharged through each diversion hole 4, which can evenly cover the surface of the activated carbon particles, and is diverted through each diversion plate 25 to avoid excessively high or low local concentrations;

At the same time, when the pressing plate 18 is pressed against the activated carbon, the spring 17 is compressed to ensure that the pressing plate 18 and the limiting plate 19 can be stuck on the activated carbon, making it easy for the activated carbon to rotate. When the lower pressing cylinder 10 moves downward, it can also drive the supporting ring 11 to move downward, thereby allowing each heating rod 13 to move downward synchronously, and the activator is heated by the heat conduction wire 14. The bottom end of the heating rod 13 can contact the insulating cone 9, and the heating rod 13 can pass through the insulating cone 9. The shape of the heating rod 13 rotates along the axis point where the heating rod 13 is connected to the support ring 11, so that each heating rod 13 can be tilted and gathered on the outside of the activated carbon, and the first electric push rod 27 drives the slider 28 to move, and then the second electric push rod 29 is moved, and the second electric push rod 29 drives the reinforcing frame 26 to rotate along the axis point where the reinforcing frame 26 is connected to the base 1, so that the activation furnace 2 can deflect on the base 1, and the activating agent that is easy to atomize is sprayed out through the first conduit 3 and the diversion hole 4, and then reciprocates through the output end of the second electric push rod 29, so as to realize the function of shaking the activation furnace 2, and the activating agent that is easy to atomize wraps the activated carbon, thereby ensuring the activation effect of the activated carbon.

[0047] Different from the prior art, the present application discloses an activated carbon preparation and activation device for spontaneously circulating formaldehyde filtration. The atomized activator is dispersed in the form of tiny droplets or aerosols, which can evenly cover the surface of the activated carbon particles, and is diverted through each diversion plate 25 to avoid local concentration being too high or too low. Each heating rod 13 is synchronously displaced downward, and the activator is heated by the heat conduction wire 14, so that the droplets are quickly vaporized at high temperature, so that it can quickly penetrate into the interior of the carbon particles at high temperature, evenly etch the pores, and avoid local over-activation or insufficient activation. Each heating rod 13 can be tilted and gathered on the outside of the activated carbon, so that the activator can directly act on the deep pores of the carbon material and reduce heat energy waste. The activation furnace 2 can deflect on the base 1. After the easily atomized activator is sprayed out through the first conduit 3 and the diversion hole 4, it reciprocates through the output end of the second electric push rod 29 to realize the function of shaking the activation furnace 2. The easily atomized activator wraps the activated carbon to ensure the activation effect of the activated carbon.

A preparation method, as claimed in any one of claims 1 to 9, wherein the activated carbon preparation and activation device for spontaneous circulation formaldehyde filtration is characterized in that: The following steps are included: Step 1: Place the activated carbon on the pad (5), support the activated carbon via the support block (6), then close the door panel (30), rotate the inner wire ring (23), and then enable the lower pressure cylinder (10) to drive the drive motor (21), the exhaust pipe (22), the temperature sensor (20), the rotating shaft (15) and the slide rod (16) to move downward, so that the pressing plate (18) and the limiting plate (19) can press against the top of the activated carbon; Step 2: The activator is atomized by the atomizer (7) and transported to the first duct (3) through the second duct (8); the atomized activator is discharged through each diversion hole (4) to evenly cover the surface of the activated carbon particles, and is diverted through each diversion plate (25) to avoid excessively high or low local concentrations; Step three, the drive motor (21) is started at the same time, and the output end of the drive motor (21) drives the rotating shaft (15), the sliding rod (16), the spring (17), the pressing plate (18) and the limiting plate (19) to rotate, thereby allowing the activated carbon to rotate. At the same time, when the pressing plate (18) is pressed against the activated carbon, the spring (17) is compressed to ensure that the pressing plate (18) and the limiting plate (19) can be stuck on the activated carbon, making it easy for the activated carbon to rotate; Step 4: When the lower pressing cylinder (10) moves downward, it can also drive the support ring (11) to move downward, thereby causing each heating rod (13) to move downward synchronously, and the activating agent is heated by the heat conduction wire (14); Step 5, the bottom end of the heating rod (13) can be in contact with the insulating cone (9), and the heating rod (13) can be rotated along the axis point of the connection between the heating rod (13) and the support ring (11) through the shape of the insulating cone (9), so that each heating rod (13) can be tilted and gathered on the outside of the activated carbon; Step six, when in use, the first electric push rod (27) drives the slider (28) to move, which in turn causes the second electric push rod (29) to move, and the second electric push rod (29) drives the reinforcing frame (26) to rotate along the axis point of the connection between the reinforcing frame (26) and the base (1), so that the activation furnace (2) can deflect on the base (1), and the activating agent that is easy to atomize is sprayed out through the first conduit (3) and the diversion hole (4), and then reciprocates through the output end of the second electric push rod (29), thereby realizing the function of shaking the activation furnace (2), and the activating agent that is easy to atomize wraps the activated carbon, thereby ensuring the activation effect of the activated carbon.
