Description

Technical Field

[0001] This utility model relates to the field of graphene, specifically a graphene production preparation device with gas purification function. Background Technology

[0002] Graphene is a two-dimensional material with a single-atom thickness and a hexagonal honeycomb lattice structure, formed by carbon atoms bonded in an sp² hybridization manner. It combines ultra-high strength, ultra-fast electrical conductivity, thermal conductivity, high light transmittance and excellent flexibility, and is known as the king of new materials. It has revolutionary application potential in the fields of electronics, energy, composite materials, and biomedicine.

[0003] In the graphene production process, the exhaust gas first passes through a front-end particulate filter, where carbon black, metal dust, and other particulate matter are trapped by the filter plate. The filtered gas then enters the combustion furnace for high-temperature oxidation treatment. As the particulate filter operates for longer periods, dust accumulates on the surface of the filter plate, gradually clogging the filter holes and narrowing the gas flow channel. To maintain normal exhaust gas flow, the blower must increase its operating power to overcome the increased pressure drop. The filter plate is cleaned by reverse blowing, a process that not only consumes compressed air but also increases energy consumption. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, in the graphene production process, the exhaust gas first passes through a front-end particulate filter, where carbon black, metal dust, and other particulate matter are trapped by the filter plate. The purified gas then enters the combustion furnace for high-temperature oxidation treatment. As the particulate filter operates for longer periods, dust accumulates on the surface of the filter plate, gradually clogging the filter pores and narrowing the gas flow channel. To maintain normal exhaust gas flow, the blower must increase its operating power to overcome the increased pressure drop. The filter plate is cleaned by reverse blowing, which not only consumes compressed air but also increases energy consumption. This invention proposes a graphene production preparation device with gas purification function.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a graphene production preparation device with gas purification function, including a particle filter body, an air inlet pipe fixedly connected to one side of the particle filter body, and a reciprocating mechanism provided on the inner wall of the particle filter body, the number of the reciprocating mechanism being five. The reciprocating mechanism includes a piston cylinder, which is fixedly connected to one side of the particulate filter body. A piston block is slidably connected to the inner wall of the piston cylinder. A piston rod is fixedly connected to one side of the piston block, with one end of the piston rod extending through to the outside of the piston cylinder. A spring is disposed between one side of the piston block and the opposite side of the inner wall of the piston cylinder, with one end of the spring fixedly connected to one side of the piston block and the other end fixedly connected to the inner wall of the piston cylinder. A connecting rod is fixedly connected to one end of the piston rod, extending through to the inner wall of the particulate filter body. A connecting plate is disposed on the inner wall of the particulate filter body. A brush plate is fixedly connected to one side of the plate by bolts. A diverter pipe is fixedly connected to one side of the air inlet pipe. A first connecting pipe is fixedly connected to the surface of the diverter pipe. There are five first connecting pipes. One end of each of the five first connecting pipes passes through the inner wall of five piston cylinders. One end of each of the five piston cylinders is fixedly connected to a second connecting pipe. One end of the second connecting pipe is fixedly connected to an air outlet pipe. One end of the air outlet pipe passes through the inner wall of the particulate filter body. A fixed pipe is fixedly connected between one end of each of the five piston cylinders and the side opposite to the particulate filter body. The piston rod and the connecting rod are slidably connected to the inner wall of the fixed pipe.

[0006] Preferably, the inner wall of the particulate filter body is fixedly connected with ten sliding rods, with each pair of sliding rods forming a group. The five groups of sliding rods pass through the inner walls of five connecting plates, and the five connecting plates are slidably connected to the inner wall of the particulate filter body through the sliding rods.

[0007] Preferably, each slide bar is fitted with a tension spring, one end of which is fixedly connected to the inner wall of the particulate filter body, and the other end of which is fixedly connected to one side of the connecting plate.

[0008] Preferably, the bottom of the particulate filter body is fixedly connected to a funnel, and the number of funnels is five, with a valve provided on the inner wall of each of the five funnels.

[0009] The advantages of this utility model are: This invention utilizes a reciprocating mechanism. Exhaust gas enters from one end of the piston cylinder, pushing the piston block to move and causing the piston rod to extend outward. During the piston block's movement, an internal spring is compressed to store energy. As the piston rod extends, it drives the connecting rod and brush plate to scrape the surface of the filter plate, removing dust. Subsequently, as the exhaust gas is discharged, the pressure inside the piston cylinder is released, and the compressed spring releases its energy, pushing the piston block and piston rod back to their initial positions. By utilizing the pressure energy of the exhaust gas itself as a power source, no additional electricity or air source is required. The pressure change drives the piston rod to reciprocate, causing the brush plate to continuously clean the surface of the filter plate, preventing filter pore blockage and dust caking, achieving automatic dust removal of the filter plate, ensuring smooth airflow, and reducing external energy consumption.

[0014] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a graphene production preparation apparatus with gas purification function. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A graphene production preparation device with gas purification function includes a particle filter body 1, an air inlet pipe 3 is fixedly connected to one side of the particle filter body 1, and a reciprocating mechanism 2 is provided on the inner wall of the particle filter body 1, the number of reciprocating mechanisms 2 being five. The reciprocating mechanism 2 includes a piston cylinder 201, which is fixedly connected to one side of the particulate filter body 1. A piston block 202 is slidably connected to the inner wall of the piston cylinder 201. A piston rod 203 is fixedly connected to one side of the piston block 202, with one end of the piston rod 203 extending through to the outside of the piston cylinder 201. A spring 204 is provided between one side of the piston block 202 and the opposite side of the inner wall of the piston cylinder 201. One end of the spring 204 is fixedly connected to one side of the piston block 202, and the other end of the spring 204 is fixedly connected to the inner wall of the piston cylinder 201. A connecting rod 205 is fixedly connected to one end of the piston rod 203, extending through to the inner wall of the particulate filter body 1. A connecting plate 20 is provided on the inner wall of the particulate filter body 1. 6. A brush plate 207 is fixedly connected to one side of the connecting plate 206 by bolts. A diversion pipe 4 is fixedly connected to one side of the air inlet pipe 3. A first connecting pipe 5 is fixedly connected to the surface of the diversion pipe 4. There are five first connecting pipes 5. One end of each of the five first connecting pipes 5 passes through the inner wall of the five piston cylinders 201. One end of each of the five piston cylinders 201 is fixedly connected to a second connecting pipe 6. One end of the second connecting pipe 6 is fixedly connected to an air outlet pipe 7. One end of the air outlet pipe 7 passes through the inner wall of the particulate filter body 1. A fixed pipe 8 is fixedly connected between one end of the five piston cylinders 201 and the side opposite to the particulate filter body 1. The piston rod 203 and the connecting rod 205 are slidably connected to the inner wall of the fixed pipe 8. By setting the reciprocating mechanism 2, the exhaust gas flows from... One end of the piston cylinder 201 enters, pushing the piston block 202 to move, which in turn causes the piston rod 203 to extend outward. During the movement of the piston block 202, the internal spring 204 is compressed to store energy. As the piston rod 203 extends, it drives the connecting rod 205 and the brush plate 207 to scrape the surface of the filter plate, removing dust. Subsequently, as the exhaust gas is discharged, the pressure inside the piston cylinder 201 is released, and the compressed spring 204 releases its energy, pushing the piston block 202 and piston rod 203 back to their initial positions. By utilizing the pressure energy of the exhaust gas itself as a power source, no additional electricity or air source is required. The pressure change drives the piston rod 203 to reciprocate, causing the brush plate 207 to continuously clean the surface of the filter plate, preventing dust from entering the filter. Filter pore blockage and dust caking enable automatic cleaning of the filter plate, ensuring smooth airflow and reducing external energy consumption. The diversion pipe 4 diverts a portion of the exhaust gas from the inlet pipe 3, guiding it into the piston cylinder 201 via the first connecting pipe 5. The pressure of the diverted exhaust gas serves as the driving source, eliminating the need for additional energy and achieving filter plate cleaning. The outlet pipe 7 guides the exhaust gas discharged from the piston cylinder 201 via the second connecting pipe 6 back to the first filter plate, ensuring that particles in the diverted exhaust gas are still effectively filtered. The fixing pipe 8 seals the gaps between the movable rod and the piston cylinder 201, and between the connecting rod 205 and the inner wall of the particle filter body 1.It can prevent exhaust gas from leaking to the outside through the gaps in the movable rod and connecting rod 205 during operation. It can also guide and recover any exhaust gas that leaks from the gaps, and then this gas, along with the exhaust gas inside the piston cylinder 201, is discharged through the second connecting pipe 6.

[0015] Reference Figure 2 Ten slide rods 9 are fixedly connected to the inner wall of the particulate filter body 1. Each pair of slide rods 9 forms a group, and the five groups of slide rods 9 pass through the inner wall of the five connecting plates 206. The five connecting plates 206 are slidably connected to the inner wall of the particulate filter body 1 through the slide rods 9. The slide rods 9 can guide the reciprocating connecting plates 206 and brush plates 207 to ensure that the connecting plates 206 and brush plates 207 move along the preset path. Reference Figure 4 Each slide bar 9 is fitted with a tension spring 10. One end of the tension spring 10 is fixedly connected to the inner wall of the particle filter body 1, and the other end of the tension spring 10 is fixedly connected to one side of the connecting plate 206. With the setting of the tension spring 10, after the piston rod 203 and the connecting rod 205 push the brush plate 207 to complete one cleaning, the rebound force of the tension spring 10 drives the brush plate 207 to move in the opposite direction to achieve automatic reset, ensuring that the brush plate 207 stably and continuously cleans the filter plate surface in both directions during reciprocating motion. Reference Figure 5 The bottom of the particulate filter body 1 is fixedly connected to a funnel 11. There are five funnels 11, and each of the five funnels 11 has a valve on its inner wall. The funnels 11 can collect particles that fall off the surface of the filter plate during the reciprocating cleaning process of the brush plate 207. The inner wall of the funnel 11 is smooth and inclined, which facilitates the automatic sliding of particles under gravity and their concentration in the bottom dust collection area. The valve installed below the funnel 11 can discharge the collected particles.

[0016] Working principle: The particulate filter body 1 forms a physical barrier through the filter plate material, blocking particles with a diameter larger than the pore size of the medium. While allowing gas to pass through, it captures suspended particulate matter, ultimately achieving gas-particle separation. This is existing technology and will not be elaborated further. Waste gas generated during graphene production enters the particulate filter body 1 through the inlet pipe 3. As waste gas continuously enters, some of it is diverted to the diversion pipe 4, and then through the first connecting pipe 5 connected to the diversion pipe 4 into the piston cylinder 201. As waste gas continues to flow in, the gas pressure inside the piston cylinder 201 gradually increases, pushing the piston block 202 outward. Simultaneously, this moves the piston rod 203 and the connecting rod 205. During this process, the piston block 202 compresses the spring 204 to store elastic potential energy. When the connecting rod 205 moves, it drives the connecting plate 206 and the brush plate 207 to slide along the surface of the slide rod 9, while simultaneously stretching the tension spring 10. The stretched tension spring 10 stores elastic potential energy, and the brush plate 207 cleans the surface of the filter plate during the sliding process. When the piston block 202 inside the piston cylinder 201 moves to the other end, the second connecting pipe 6 will leak out. At this time, the exhaust gas inside the piston cylinder 201 will be discharged through the second connecting pipe 6. This exhaust gas will re-enter the particle filter body 1 through the exhaust pipe 7 and be filtered by the filter plate. At this time, the pressure inside the piston cylinder 201 decreases, and the compressed spring 204 and the stretched tension spring 10 will rebound synchronously, thereby driving the piston rod 203, connecting rod 205, connecting plate 206 and brush plate 207 to reset. Through the continuous entry of exhaust gas, the filter plate is continuously cleaned.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
