Description

Technical Field

[0001] The present invention relates to the technical field of activation devices. More specifically, the present invention relates to an activation device and a preparation method for preparing activated carbon for spontaneous cyclic filtration and purification of formaldehyde. Background Art

[0002] Activated carbon is a kind of carbon treated specially. Organic raw materials such as fruit shells, coal, wood, etc. are heated under the condition of isolating air to reduce non-carbon components. This process is called carbonization. Then it reacts with gas, and its surface is eroded to produce a structure with developed micropores. This process is called activation. Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, countless fine pores are formed on the surface of activated carbon. When preparing activated carbon, an activation device for preparing activated carbon is needed.

[0003] Among them, the patent with the publication number CN219603263U discloses an activation device for preparing activated carbon, including a preparation cylinder. A feed inlet is opened on the upper surface of the preparation cylinder, and a dust-proof cover is arranged outside the feed inlet. Steam boxes are symmetrically arranged outside the preparation cylinder. An air inlet pipe is communicated with the outside of each of the two steam boxes. Sealing covers are arranged at the air inlet ends of the two air inlet pipes. Air pumps are fixedly connected to the upper surfaces of the two steam boxes. The air inlet ends of the two air pumps are communicated with the inside of the steam boxes through pipelines, and the air outlet ends of the two air pumps are communicated with the inside of the preparation cylinder through pipelines;

[0004] When this structure is in use, through the arranged air pumps, steam boxes and air inlet pipes, when the raw materials need to be activated, the raw materials are first placed in the preparation cylinder. At this time, the heater starts to operate to bake the raw materials in the preparation cylinder. While the heater is operating, the staff can open the sealing cover and add steam into the steam box through the air inlet pipe. At this time, the air pump starts to operate, and the steam in the steam box is transmitted into the preparation cylinder through the pipeline. At this time, the organic raw materials can be comprehensively activated, so that the prepared activated carbon has better adsorption capacity. However, when this structure is in use, it is not easy for the steam and the heat during heating to fully contact the activated carbon, and the function of wrapping and activating the activated carbon with the steam and the heat during heating cannot be realized, resulting in poor activation effect. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an activation device and a preparation method for preparing activated carbon for spontaneous cyclic filtration and purification of formaldehyde, aiming to solve the problems raised in the above background art.

[0006] The present invention provides the following technical solutions: An activation device for preparing activated carbon for spontaneous cyclic filtration and purification of formaldehyde, including a base, and an activation assembly is arranged on the base;

[0007] The activation assembly includes an activation furnace arranged on the base. A first conduit is provided at the bottom of the inner cavity of the activation furnace.

[0008] A heat insulation cone for blocking is provided at the top of the first conduit. An adjustable pressing cylinder is provided at the top of the activation furnace. The pressing cylinder is slidably connected to the activation furnace. A support ring is installed at the bottom of the pressing cylinder through bolts. A number of dislocation openings are provided at the bottom of the support ring. And an angle-adjustable heating rod is hinged in each dislocation opening. And a heat conduction wire is sleeved on each heating rod. A rotating shaft is rotatably connected to the middle of the pressing cylinder. The bottom of the rotating shaft is slidably connected to a sliding rod through a chute and a slider. A spring is arranged between the sliding rod and the rotating shaft. A pressing plate is fixedly arranged at the bottom of the sliding rod. A number of limiting plates are distributed on the outside of the pressing plate. A driving motor for driving the rotating shaft to rotate is provided at the top of the pressing cylinder. A temperature sensor for temperature detection is arranged on one side of the surface of the driving motor. The temperature sensor penetrates through the pressing cylinder and extends to the middle of the activation furnace. Exhaust pipes for guiding the flow are provided at the top of the pressing cylinder and on the outside of the activation furnace. And a valve is embedded on each exhaust pipe;

[0009] Optionally, in a possible implementation manner, an internal thread ring is threadedly connected to the outside of the pressing cylinder. The internal thread ring is located at the top of the activation furnace. The internal thread ring is rotatably connected to the activation furnace. A number of L-shaped rods are distributed in the middle of the first conduit. And a shunt plate is provided at the top of each L-shaped rod. The shunt plate is located outside the cushion plate. The cushion plate is rotatably connected to the shunt plate. A reinforcing frame is installed outside the activation furnace through bolts. The reinforcing frame is hinged to the base. A first electric push rod is installed at the bottom of the base through bolts. The output end of the first electric push rod is provided with a slider. The slider is slidably connected to the base. A second electric push rod is hinged to the slider. The output end of the second electric push rod extends to the reinforcing frame and is hinged to the reinforcing frame. A door panel is hinged to the outside of the activation furnace;

[0010] A preparation method uses the above-mentioned activation device for preparing activated carbon for spontaneously circulating and filtering formaldehyde, and is characterized in that: it includes the following steps,

[0011] Step 1: The staff installs the device at the designated position. When preparing and activating the activated carbon, the staff opens the door panel, places the activated carbon on the cushion plate, supports the activated carbon through the supporting block, then closes the door panel, and by rotating the internal thread ring, the pressing cylinder can drive the driving motor, exhaust pipe, temperature sensor, rotating shaft, and sliding rod to move downward, so that the pressing plate and the limiting plate can press against the top of the activated carbon.

[0012] Step 2: The atomizer atomizes the activator and transports it to the first conduit through the second conduit. The atomized activator is discharged through each shunt 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 shunted through each shunt plate to avoid too high or too low local concentration.

[0013] Step 3: At the same time, the driving motor is started. The output end of the driving motor drives the rotating shaft, sliding rod, spring, pressing plate, and limiting plate to rotate, so that the activated carbon can rotate, making the activator evenly distributed, which helps to form more regular pore micropores and mesopores in the carbon structure, improving the adsorption capacity of the activated carbon. At the same time, when the pressing plate presses against the activated carbon, the spring is compressed, ensuring that the pressing plate and the limiting plate can be stuck on the activated carbon, facilitating the rotation of the activated carbon.

[0014] Step 4: And when the pressing cylinder moves downward, it can also drive the supporting ring to move downward, so that each heating rod moves downward synchronously. The activator is heated through the heat conduction wire, so that the droplets are quickly vaporized at high temperature, and it can quickly penetrate into the interior of the carbon particles at high temperature, evenly etching the pores, avoiding local over-activation or under-activation.

[0015] Step 5: And the bottom end of the heating rod can contact the heat insulation conical cylinder. The heating rod can rotate along the axis point of the connection between the heating rod and the supporting ring according to the shape of the heat insulation conical cylinder, so that each heating rod can be inclined and gathered outside the activated carbon, facilitating the direct action of the activator on the deep pores of the carbon material and reducing heat energy waste.

[0016] Step 6: At the same time, during use, the first electric push rod drives the slider to move, so that the second electric push rod moves. The second electric push rod drives the strengthening frame to rotate along the axis point of the connection between the strengthening frame and the base, so that the activation furnace can deflect on the base. It is easy for the atomized activator to be sprayed out through the first conduit and the shunt holes, and through the reciprocating movement of the output end of the second electric push rod, the function of shaking the activation furnace is realized, which is easy for the atomized activator to wrap the activated carbon and ensure the activation effect of the activated carbon.

[0017] The technical effects and advantages of the present invention:

[0018] 1. In the present invention, the activator is atomized by an atomizer and transported through a second conduit into a first conduit. The atomized activator is discharged through each shunt hole. The atomized activator is dispersed in the form of tiny droplets or aerosols, which can uniformly cover the surface of activated carbon particles and is shunted by each shunt plate to avoid excessive or insufficient local concentration.

[0019] 2. In the present invention, the activated carbon rotates, enabling the activator to be 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 presses against the activated carbon, the spring is compressed under force to ensure that the pressing plate and the limiting plate can be stuck on the activated carbon, facilitating the rotation of the activated carbon.

[0020] 3. In the present invention, 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. The activator is heated through a heat conduction wire, enabling the droplets to quickly vaporize at high temperature and rapidly penetrate into the interior of the carbon particles at high temperature, uniformly etching the pores and avoiding local over-activation or insufficient activation.

[0021] 4. In the present invention, the heating rod can rotate along the axis point of the connection between the heating rod and the support ring in the shape of a heat-insulating conical cylinder, and then each heating rod can be inclined and gathered outside the activated carbon, facilitating the direct action of the activator on the deep pores of the carbon material and reducing heat energy waste.

[0022] 5. In the present invention, the first electric push rod drives the slider to move, and then the second electric push rod moves. The second electric push rod drives the reinforcing frame to rotate along the axis point of the connection between the reinforcing frame and the base, enabling the activation furnace to deflect on the base. After the atomized activator is ejected through the first conduit and the shunt holes, the reciprocating movement of the output end of the second electric push rod realizes the function of shaking the activation furnace, facilitating the atomized activator to wrap the activated carbon and ensuring the activation effect of the activated carbon.

[0023] In summary, through the coordinated use of each structure, the atomized activator is dispersed in the form of tiny droplets or aerosols, which can uniformly cover the surface of activated carbon particles and is shunted by each shunt plate to avoid excessive or insufficient local concentration. Each heating rod moves downward synchronously, and the activator is heated through a heat conduction wire, enabling the droplets to quickly vaporize at high temperature and rapidly penetrate into the interior of the carbon particles at high temperature, uniformly etching the pores and avoiding local over-activation or insufficient activation. Each heating rod can be inclined and gathered outside the activated carbon, facilitating the direct action of the activator on the deep pores of the carbon material and reducing heat energy waste. The activation furnace can deflect on the base. After the atomized activator is ejected through the first conduit and the shunt holes, the reciprocating movement of the output end of the second electric push rod realizes the function of shaking the activation furnace, facilitating the atomized activator to wrap the activated carbon and ensuring the activation effect of the activated carbon.

[0034] As shown in the attached Figure 1 - Figure 7 An activation device for preparing activated carbon for self-circulating filtration and purification of formaldehyde. Through the activation component arranged on the base 1, 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 shunted by each flow dividing plate 25 to avoid too high or too low local concentration. Each heating rod 13 moves downward synchronously, and the activator is heated through the heat conduction wire 14, so that the droplets are quickly vaporized at high temperature and rapidly penetrate into the interior of the carbon particles at high temperature, uniformly etching pores to avoid local over-activation or insufficient activation. Each heating rod 13 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. The activation furnace 2 can deflect on the base 1. After the easily atomized activator is ejected through the first conduit 3 and the flow dividing holes 4, the output end of the second electric push rod 29 reciprocates 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, and the specific structure of the component is as follows;

[0035] The activation component includes an activation furnace 2 arranged on the base 1. The bottom of the inner cavity of the activation furnace 2 is provided with a first conduit 3. A number of flow dividing holes 4 for guiding are distributed on the first conduit 3. The top of the first conduit 3 is provided with a cushion plate 5. The top of the cushion plate 5 is rotatably connected with a support block 6. An atomizer 7 is arranged outside the activation furnace 2. A second conduit 8 for guiding is arranged on the atomizer 7. The second conduit 8 extends to the bottom of the first conduit 3 and is communicated with the first conduit 3;

[0036] At the top of the first conduit 3, there is a heat-insulating cone 9 for blocking. At the top of the activation furnace 2, there is a downward pressure cylinder 10 that can be adjusted up and down. The downward pressure cylinder 10 is slidably connected to the activation furnace 2. At the bottom of the downward pressure cylinder 10, a support ring 11 is installed by bolts. At the bottom of the support ring 11, a number of staggered openings 12 are provided, and in each of the staggered openings 12, a heating rod 13 with adjustable angle is hinged. A heat conduction wire 14 is sleeved on each heating rod 13. In the middle of the downward pressure cylinder 10, a rotating shaft 15 is rotatably connected. At the bottom of the rotating shaft 15, a sliding rod 16 is slidably connected through a chute and a slider. A spring 17 is provided between the sliding rod 16 and the rotating shaft 15. At the bottom of the sliding rod 16, a pressing plate 18 is fixedly provided. A number of limiting plates 19 are distributed on the outer side of the pressing plate 18. At the top of the downward pressure cylinder 10, a driving motor 21 for driving the rotating shaft 15 to rotate is provided. On one side of the surface of the driving motor 21, a temperature sensor 20 for temperature detection is provided. The temperature sensor 20 penetrates through the downward pressure cylinder 10 and extends to the middle of the activation furnace 2. Exhaust pipes 22 for guiding are provided at the top of the downward pressure cylinder 10 and on the outer side of the activation furnace 2, and valves are embedded in each of the exhaust pipes 22;

[0037] An internal thread ring 23 is threadedly connected to the outer side of the downward pressure cylinder 10. The internal thread ring 23 is located at the top of the activation furnace 2. The internal thread ring 23 is rotatably connected to the activation furnace 2. A number of L-shaped rods 24 are distributed in the middle of the first conduit 3, and at the top of each L-shaped rod 24, a flow dividing plate 25 is provided. The flow dividing plate 25 is located outside the cushion plate 5. The cushion plate 5 is rotatably connected to the flow dividing plate 25. A reinforcing frame 26 is installed on the outer side of the activation furnace 2 by bolts. The reinforcing frame 26 is hinged to the base 1. At the bottom of the base 1, a first electric push rod 27 is installed by bolts. The output end of the first electric push rod 27 is provided with a slider 28. The slider 28 is slidably connected to the base 1. A second electric push rod 29 is hinged to the slider 28. The output end of the second electric push rod 29 extends to the reinforcing frame 26 and is hinged to the reinforcing frame 26. A door panel 30 is hinged to the outer side of the activation furnace 2;

[0038] A preparation method uses the above-mentioned activation device for preparing activated carbon for self-circulating filtration and purification of formaldehyde, and includes the following steps

[0039] Step 1, the staff installs the device at a designated position. When preparing and activating the activated carbon, the staff opens the door panel 30, places the activated carbon on the cushion plate 5, supports the activated carbon through the supporting blocks 6, then closes the door panel 30, and by rotating the internal thread ring 23, the downward 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 plates 19 can press against the top of the activated carbon;

[0040] Step 2: The activator is atomized by the atomizer 7 and transported through the second conduit 8 into the first conduit 3. The atomized activator is discharged through each shunt hole 4. The atomized activator is dispersed in the form of tiny droplets or aerosol, which can evenly cover the surface of the activated carbon particles and is shunted by each shunt plate 25 to avoid excessive or insufficient local concentration;

[0041] Step 3: Meanwhile, the drive motor 21 is started. 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 enabling the activated carbon to rotate, making the activator evenly distributed, helping to form more regular pore micropores and mesopores in the carbon structure, and improving the adsorption capacity of the activated carbon. At the same time, when the pressing plate 18 presses against the activated carbon, the spring 17 is compressed, ensuring that the pressing plate 18 and the limiting plate 19 can be stuck on the activated carbon, facilitating the rotation of the activated carbon;

[0042] Step 4: And when the pressing cylinder 10 moves downward, it can also drive the support ring 11 to move downward, thereby enabling each heating rod 13 to move downward synchronously. The activator is heated through the heat conduction wire 14, causing the droplets to rapidly vaporize at high temperature, enabling them to quickly penetrate into the interior of the carbon particles at high temperature and evenly etch the pores, avoiding local over-activation or insufficient activation;

[0043] Step 5: And the bottom end of the heating rod 13 can contact the heat insulation cone 9. The heating rod 13 can rotate along the axis point of the connection between the heating rod 13 and the support ring 11 according to the shape of the heat insulation cone 9, thereby enabling each heating rod 13 to be inclined and gather outside the activated carbon, facilitating the direct action of the activator on the deep pores of the carbon material and reducing heat energy waste;

[0044] Step 6: Meanwhile, during use, the first electric push rod 27 drives the slider 28 to move, thereby enabling the second electric push rod 29 to move. The second electric push rod 29 drives the strengthening frame 26 to rotate along the axis point of the connection between the strengthening frame 26 and the base 1, enabling the activation furnace 2 to deflect on the base 1. It is easy for the atomized activator to be ejected through the first conduit 3 and the shunt holes 4. Through the reciprocating motion of the output end of the second electric push rod 29, the function of shaking the activation furnace 2 is realized, facilitating the atomized activator to wrap the activated carbon and ensuring the activation effect of the activated carbon.

[0045] When used according to the above structure, the activated carbon is placed on the pad 5 and supported by the supporting block 6. Then, the door panel 30 is closed. By rotating the internal thread ring 23, the pressing 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. Subsequently, the pressing plate 18 and the limiting plate 19 can press against the top of the activated carbon. The activator is atomized by the atomizer 7 and conveyed to the first conduit 3 through the second conduit 8. The atomized activator is discharged through each shunt hole 4, which can evenly cover the surface of the activated carbon particles and is shunted by each shunt plate 25 to avoid excessive or too low local concentration.

[0046] At the same time, the driving motor 21 is started. The output end of the driving 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. Subsequently, the activated carbon can rotate. At the same time, when the pressing plate 18 presses against the activated carbon, the spring 17 is compressed by the force to ensure that the pressing plate 18 and the limiting plate 19 can be stuck on the activated carbon, which is conducive to the rotation of the activated carbon. And when the pressing cylinder 10 moves downward, it can also drive the supporting ring 11 to move downward. Subsequently, each heating rod 13 moves downward synchronously. The activator is heated through the heat conduction wire 14. And the bottom end of the heating rod 13 can contact with the heat insulation cone 9. The heating rod 13 can rotate along the axis point of the connection between the heating rod 13 and the supporting ring 11 according to the shape of the heat insulation cone 9. Subsequently, each heating rod 13 can be inclined and gathered outside the activated carbon. The first electric push rod 27 drives the slider 28 to move. Subsequently, the second electric push rod 29 moves. 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. It is easy for the atomized activator to be sprayed out through the first conduit 3 and the shunt holes 4. Through the reciprocating movement of the output end of the second electric push rod 29, the function of shaking the activation furnace 2 is realized. It is easy for the atomized activator to wrap the activated carbon to ensure the activation effect of the activated carbon.

[0047] Different from the prior art, the present application discloses an activation device for preparing activated carbon for spontaneous cyclic filtration and purification of formaldehyde. The atomized activator is dispersed in the form of tiny droplets or aerosol, which can evenly cover the surface of activated carbon particles. And it is shunted by each flow dividing plate 25 to avoid too high or too low local concentration. Each heating rod 13 synchronously moves downward, and the activator is heated through the heat conduction wire 14, so that the droplets are quickly vaporized at high temperature, and quickly penetrate into the interior of carbon particles at high temperature, uniformly etching pores to avoid local over-activation or insufficient activation. Each heating rod 13 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, reducing heat energy waste. The activation furnace 2 can deflect on the base 1. After the easily atomized activator is ejected through the first conduit 3 and the shunt holes 4, the output end of the second electric push rod 29 reciprocates 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.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

A method for preparing and activating activated carbon for spontaneously circulating formaldehyde filtration, using the device for preparing and activating activated carbon for spontaneously circulating formaldehyde filtration as claimed in claim 7, 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.
