Description

Technical Field

[0001] This invention belongs to the field of graphite production technology, specifically a desulfurization and denitrification device for graphite production. Background Technology

[0002] Graphite, as an important industrial raw material, is widely used in batteries, lubricants, refractory materials, and conductive materials. During graphite production, the uniformity and consistency of particle size have a significant impact on product quality and subsequent processing performance.

[0003] However, existing technologies that use mechanical grinding and sieving for particle size control have the following drawbacks: Traditional screening equipment (such as vibrating screens) is prone to reduced screening efficiency when processing fine or highly viscous graphite particles due to particle accumulation or screen clogging, which seriously affects production continuity and equipment operation stability. At the same time, mechanical grinding and screening processes are difficult to achieve high-precision particle size control, resulting in a wide size distribution of processed graphite particles, which is difficult to meet the stringent requirements for size uniformity in high-performance graphite products.

[0004] Furthermore, traditional processes rely heavily on manual operation or semi-automated equipment, which are complex and inefficient, increasing labor intensity and causing poor particle processing consistency due to human factors. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a desulfurization and denitrification device for graphite production, so as to at least partially solve the above technical problems.

[0006] The technical solution adopted in this invention is as follows: This invention proposes a desulfurization and denitrification device for graphite production, comprising: A graphite particle processing assembly includes a limiting frame, a supporting frame plate, a particle extrusion plate, a gantry-type blocking plate, and a pusher plate. The supporting frame plate is located inside the limiting frame, and the particle extrusion plate is located above the supporting frame plate. The particle extrusion plate is smaller than the supporting frame plate to facilitate its engagement with the supporting frame plate. A fixing plate is provided on one side of the supporting frame plate, and an installation frame is provided above the fixing plate. Graphite particles are located inside the supporting frame plate and the installation frame. The gantry-type blocking plate is located on one side of the fixing plate, and a limiting groove is formed on the surface of the gantry-type blocking plate. The pusher plate is located inside the limiting groove. The working cylinder has an upper processing chamber and a lower processing chamber inside. A partition plate is provided between the upper and lower processing chambers. The surface of the partition plate has particle feeding holes.

The size of the graphite particles before processing is larger than the multiple sets of reserved particle filter holes, and the size of the graphite particles after processing is smaller than the multiple sets of reserved particle filter holes. The multiple sets of reserved particle filter holes at the bottom of the supporting frame plate and the multiple sets of reserved particle filter holes at the bottom of the limiting frame body overlap with each other, so that the graphite particles fall off to the outside of the graphite particle processing component after processing. The outer side of the limiting frame is provided with a feeding screen, and the surface of the feeding screen is provided with several sets of limiting holes, the size of which is larger than the size of the graphite particles before processing.

[0008] In one embodiment of the present invention, a hydraulic cylinder is provided at the top of the inner wall of the limiting frame, the working end of the hydraulic cylinder is connected to the top of the particle extrusion plate, and a hydraulic cylinder control button is provided on the top surface of the fixing plate. Graphite particles fall into the interior of the mounting frame, the mounting frame is pressed, and its bottom contacts the hydraulic cylinder control button. The hydraulic cylinder is electrically controlled by the hydraulic cylinder control button through a transmission line.

[0009] In one embodiment of the present invention, an electric telescopic device is provided at the top of the inner wall of the limiting frame. The working end of the electric telescopic device is connected to one side of the pusher plate. The top surface of the fixing plate is also provided with a first electric telescopic device control button. Graphite particles fall into the interior of the mounting frame, the mounting frame is compressed, and its bottom contacts the first electric telescopic device control button. The electric telescopic device is electrically controlled to the first electric telescopic device control button through a conduction line.

[0010] In one embodiment of the present invention, a second electric telescopic control button is provided on the side wall of the granule extrusion plate. The pusher plate moves toward the granule extrusion plate, and the outer wall of the pusher plate contacts the second electric telescopic control button. The electric telescopic device is electrically connected to the second electric telescopic control button through a transmission line, and the pusher plate moves away from the granule extrusion plate.

[0011] In one embodiment of the present invention, a drive motor is provided at the bottom of the inner wall of the upper processing cavity, a rotating rod is provided at the working end of the drive motor, the graphite particle processing assembly is provided on the outer wall of the rotating rod, a bearing seat is provided at the top of the inner wall of the upper processing cavity, and one end of the rotating rod is provided inside the bearing seat.

[0012] In one embodiment of the present invention, buffer damping rods are provided at the four corners of the top surface of the fixed plate, and the top surfaces of the four buffer damping rods are located at the bottom of the mounting frame. The bottom of the lower processing chamber is provided with a particle placement plate, which receives the processed graphite particles. The four corners of the bottom surface of the particle placement plate are provided with shock-absorbing damping rods.

[0013] In one embodiment of the present invention, four discharge pipes are provided on the outer side of the working cylinder, one end of each of the four discharge pipes is located inside the lower processing chamber, and a solenoid valve is provided on the outer side of each of the four discharge pipes. A solenoid valve control button is provided at the bottom of the particle placement plate. Graphite particles fall into the interior of the particle placement plate and are pressed to contact the solenoid valve control button. The solenoid valve is electrically connected to the solenoid valve control button through a conduction line.

[0014] In one embodiment of the present invention, a gas purifier is provided at the top of the working cylinder, and a gas delivery pipe is provided at the working end of the gas purifier. The other end of the gas delivery pipe is located inside the upper processing chamber to purify the gas during the processing of graphite particles.

[0015] In one embodiment of the present invention, a graphite particle inlet is provided on the outside of the working cylinder, and a remote controller is provided on the outside of the working cylinder. The remote controller is electrically connected to an electric hydraulic cylinder, an electric telescopic device and a solenoid valve through a transmission line. The bottom surface of the working cylinder is provided with two support columns, and the bottom surface of each support column is provided with a protective plate. The bottom surface of the two protective plates is provided with anti-slip texture.

[0016] The beneficial effects of the technical solution of this invention are as follows: This invention achieves the extrusion and size screening of graphite particles through the coordinated operation of a limiting frame, a supporting frame, a particle extrusion plate, a gantry-type baffle plate, and a pusher plate in a graphite particle processing component. The size matching design of the supporting frame and the particle extrusion plate inside the limiting frame (the particle extrusion plate is smaller than the supporting frame for easy engagement), coupled with the drive of a hydraulic cylinder, allows the particle extrusion plate to apply uniform pressure to the graphite particles within the supporting frame, extruding larger graphite particles before processing to a smaller, more suitable size. The processed graphite particles are smaller than the apertures of the multiple sets of pre-reserved particle filter holes at the bottom of the supporting frame and the limiting frame, thus naturally falling to the outside of the component through the overlapping filter holes. Larger particles before processing are effectively intercepted because their size exceeds the filter holes. This size-based screening mechanism not only ensures the uniformity of graphite particle size but also avoids particle clogging problems that may occur in traditional screening processes, significantly improving screening efficiency and the continuity of particle processing.

[0017] This invention achieves a high degree of automation in the particle extrusion, feeding, and screening processes through an electrical control connection of a hydraulic cylinder, an electric telescopic device, and corresponding control buttons (hydraulic cylinder control button, first electric telescopic device control button, and second electric telescopic device control button). When graphite particles fall into the mounting frame, the frame is pressurized, triggering the hydraulic cylinder control button and the first electric telescopic device control button. These buttons respectively drive the hydraulic cylinder to push the particle extrusion plate for extrusion and the electric telescopic device to drive the feeding plate to push the particles. During its movement, the feeding plate contacts the second electric telescopic device control button on the side wall of the particle extrusion plate, triggering the electric telescopic device to reverse its movement and reset the feeding plate. This closed-loop control system, through the coordination of mechanical and electrical control, reduces the need for manual intervention, improves operational stability and consistency, and simultaneously reduces the labor intensity and error rate of operators.

[0018] In this invention, the upper and lower processing chambers inside the working cylinder achieve optimized stratified processing and particle transport through a partition plate and particle feeding holes on its surface. The graphite particle processing component is located in the upper processing chamber. The processed graphite particles are smaller than the diameter of the particle feeding holes, allowing them to smoothly fall from the upper processing chamber into the lower processing chamber for subsequent processing, while larger particles are intercepted by the partition plate in the upper chamber. This stratification not only enables phased management of particle processing but also further enhances the particle size screening effect through the size control of the particle feeding holes. In addition, the feed barrier on the outside of the limiting frame and the limiting holes on its surface (larger than the unprocessed graphite particles) effectively prevent particles from scattering or overflowing when entering the processing component, ensuring the continuity of particle transport and the cleanliness of the device operation.

[0019] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] A desulfurization and denitrification device for graphite production according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0024] like Figures 1 to 7 As shown, this embodiment of the invention provides a desulfurization and denitrification device for graphite production, including: a graphite particle processing component 1, the graphite particle processing component 1 including a limiting frame 2, a bearing frame plate 4, a particle extrusion plate 7, a gantry-type baffle plate 11 and a pusher plate 13, the bearing frame plate 4 is disposed inside the limiting frame 2, the particle extrusion plate 7 is disposed above the bearing frame plate 4, the size of the particle extrusion plate 7 is smaller than the size of the bearing frame plate 4, so that the particle extrusion plate 7 can be engaged inside the bearing frame plate 4, a fixing plate 8 is provided on one side of the bearing frame plate 4, an installation frame 10 is provided above the fixing plate 8, graphite particles are disposed inside the bearing frame plate 4 and the installation frame 10, the gantry-type baffle plate 11 is disposed on one side of the fixing plate 8, a limiting groove 12 is formed on the surface of the gantry-type baffle plate 11, and the pusher plate 13 is disposed inside the limiting groove 12; The working cylinder 18 has an upper processing chamber 21 and a lower processing chamber 22 inside. A partition plate 26 is provided between the upper processing chamber 21 and the lower processing chamber 22. The surface of the partition plate 26 has a particle feeding hole 27. The size of the processed graphite particles is smaller than the size of the particle feeding hole. The graphite particle processing component 1 is located inside the upper processing chamber 21. The graphite particles before processing are also located inside the upper processing chamber 21.

[0025] In a specific application of this invention, at the start of operation, the graphite particles, before processing, enter the interior of the mounting frame 10 and fall above the supporting frame plate 4. The supporting frame plate 4 is located inside the limiting frame 2, which serves as the overall support and constraint structure, ensuring the stability of the supporting frame plate 4 during particle processing and preventing displacement or scattering due to external forces. The size design of the supporting frame plate 4 is sufficient to accommodate enough graphite particles. Simultaneously, the particle extrusion plate 7 positioned above it applies downward pressure in a controllable manner via a hydraulic cylinder 6. The particle extrusion plate 7 is slightly smaller than the supporting frame plate 4, allowing it to tightly engage within the supporting frame plate 4, thereby uniformly extruding the graphite particles. During the extrusion process, the graphite particles are subjected to pressure from the particle extrusion plate 7, causing their internal structure to rearrange, reducing the gaps between particles, and crushing or deforming some large particles, thus forming a more uniform particle shape. This extrusion process increases the density of the graphite particles and provides a larger specific surface area for subsequent desulfurization and denitrification reactions, which is beneficial for the efficient conduct of chemical reactions.

[0026] A limiting groove 12 is formed on the surface of the portal baffle 11, and a pusher plate 13 is embedded in the limiting groove 12. The pusher plate 13 can slide in a predetermined direction within the limiting groove 12. Controlled by an electric telescopic rod, the pusher plate 13 directionally pushes the graphite particles on the support frame plate 4. The limiting groove 12 of the portal baffle 11 ensures the stability of the movement trajectory of the pusher plate 13, preventing the particles from scattering or deviating during the pushing process. At the same time, the overall structure of the portal baffle 11 can effectively block the flow of particles in other directions, ensuring that the particles can be smoothly pushed into the interior of the support frame plate 4. A fixing plate 8 is provided on one side of the support frame plate 4, and an installation frame 10 is connected above the fixing plate 8. The installation frame 10 and the support frame plate 4 together form a temporary storage space for the particles. Graphite particles enter the interior of the limiting frame 2 one after another. Some graphite particles will be distributed inside the installation frame 10. As the number of graphite particles increases, pressure will be generated on the installation frame 10. The installation frame 10 moves downward until it contacts the first electric telescopic control button 15. The electric telescopic rod works autonomously, driving the pusher plate 13 to move towards the support frame plate 4, thereby pushing the graphite particles inside the installation frame 10 into the interior of the support frame plate 4, improving the processing efficiency of graphite particles.

[0027] The interior of the working cylinder 18 is divided into an upper processing chamber 21 and a lower processing chamber 22 by a partition plate 26. The partition plate 26 has particle feeding holes 27 on its surface. The size of the particle feeding holes 27 only allows processed graphite particles (i.e., particles smaller than the feeding holes) to pass through, thus achieving the particle screening function. In the upper processing chamber 21, the extruded and pushed graphite particles gradually approach the area of ​​the partition plate 26 under the continuous action of the pusher plate 13. Some particles, having reached a fine particle state that matches the size of the feeding holes during the extrusion process, fall into the lower processing chamber 22 through the particle feeding holes 27 under the combined action of gravity and the pusher plate 13. Larger particles are blocked by the partition plate 26 and continue to be processed further in the upper processing chamber 21.

[0028] In one possible implementation, both the support frame plate 4 and the limiting frame 2 have multiple sets of reserved particle filter holes 5 at their bottoms. The size of the graphite particles before processing is larger than the multiple sets of reserved particle filter holes 5, and the size of the graphite particles after processing is smaller than the multiple sets of reserved particle filter holes 5. The multiple sets of reserved particle filter holes 5 at the bottom of the support frame plate 4 and the multiple sets of reserved particle filter holes 5 at the bottom of the limiting frame 2 overlap with each other, so that the graphite particles fall to the outside of the graphite particle processing component 1 after processing. The outside of the limiting frame 2 is provided with a feeding net 3, and the surface of the feeding net 3 is provided with several sets of limiting holes, the size of which is larger than the size of the graphite particles before processing.

[0029] In specific applications, the embodiments of the present invention utilize the dynamic coordination of the supporting frame plate 4, the limiting frame 2, and the feed barrier 3, along with the screening of multiple sets of reserved particle filter holes 5. The aperture of the multiple sets of reserved particle filter holes 5 is adjusted according to the process requirements of the graphite particles. Specifically, the graphite particles before processing (i.e., the original particles or particles that have not been fully processed) are larger than the aperture of the reserved particle filter holes 5 and therefore cannot pass through; the graphite particles after processing (i.e., the particles whose size has been reduced after extrusion and crushing) are smaller than the aperture of the reserved particle filter holes 5 and can pass through smoothly.

[0030] The bottom filter holes 5 of the supporting frame plate 4 and the limiting frame 2 overlap to form a unified particle passage channel. This not only improves screening efficiency but also ensures that the processed fine graphite particles can smoothly fall from the bottom of the supporting frame plate 4 and the limiting frame 2 into the upper processing chamber 21. The graphite particle processing component 1, as the structure for receiving screened particles, can further desulfurize and denitrify the particles. For example, by spraying a desulfurizing and denitrifying agent to fully contact the particle surface, harmful components such as sulfides and nitrogen oxides are efficiently removed. Simultaneously, the surface of the feed baffle 3 is provided with several sets of limiting holes, the diameter of which is larger than the size of the graphite particles before processing. This allows the raw graphite particles to smoothly pass into the limiting frame 2 for preliminary processing, ensuring the smoothness of the feeding process. The synergistic effect of the feed baffle 3 and the limiting frame 2 forms a continuous process from raw material input to preliminary screening, laying the foundation for further particle processing.

[0031] Before processing, the graphite particles first enter the limiting frame 2 through the limiting holes of the feed baffle 3. Within the processing space formed by the supporting frame plate 4 and the limiting frame 2, they undergo mechanical compression and crushing. During processing, the particle size gradually decreases, with some particles becoming smaller than the reserved particle filter holes 5. These smaller particles, under gravity and possible dynamic pushing, fall into the upper processing chamber 21 through the reserved particle filter holes 5 that overlap at the bottom of the supporting frame plate 4 and the limiting frame 2. Particles still larger than the filter holes are blocked inside the supporting frame plate 4 and the limiting frame 2 and continue to be processed until they meet the passing conditions. This ensures the uniformity of graphite particle size and reactivity, guaranteeing the implementation of desulfurization and denitrification.

[0032] In one possible implementation, a hydraulic cylinder 6 is provided at the top of the inner wall of the limiting frame 2. The working end of the hydraulic cylinder 6 is connected to the top of the particle extrusion plate 7. A hydraulic cylinder control button 17 is provided on the top surface of the fixing plate 8. Graphite particles fall into the interior of the mounting frame 10. The mounting frame 10 is pressed, and its bottom contacts the hydraulic cylinder control button 17. The hydraulic cylinder 6 is electrically connected to the hydraulic cylinder control button 17 through a transmission line. A second electric telescopic device control button 16 is provided on the side wall of the particle extrusion plate 7. The pusher plate 13 moves toward the particle extrusion plate 7. The outer wall of the pusher plate 13 contacts the second electric telescopic device control button 16. The electric telescopic device 14 is electrically connected to the second electric telescopic device control button 16 through a transmission line. The pusher plate 13 moves away from the particle extrusion plate 7.

[0033] The top of the inner wall of the limiting frame 2 is also provided with an electric telescopic device 14. The working end of the electric telescopic device 14 is connected to one side of the pusher plate 13. The top surface of the fixing plate 8 is also provided with a first electric telescopic device control button 15. Graphite particles fall into the interior of the mounting frame 10. The mounting frame 10 is pressed, and its bottom contacts the first electric telescopic device control button 15. The electric telescopic device 14 is electrically connected to the first electric telescopic device control button 15 through a conduction line.

[0034] In a specific application of this invention, the top of the inner wall of the limiting frame 2 is provided with a hydraulic cylinder 6 and an electric telescopic device 14, which serve as the power source for extrusion and pushing, respectively. The working end of the hydraulic cylinder 6 is connected to the top of the particle extrusion plate 7, forming a vertically controllable extrusion assembly. It can be hydraulically driven to make the particle extrusion plate 7 move up and down within the limiting frame 2, apply extrusion force to the graphite particles, promote particle crushing or particle size reduction, and provide an ideal particle shape for subsequent processing or screening.

[0035] When graphite particles fall into the mounting frame 10, the weight of the particles and the accumulated pressure cause the mounting frame 10 to sink. Simultaneously, its bottom contacts the hydraulic cylinder control button 17 and the first electric telescopic device control button 15 on the fixing plate 8. Through a conductive line, an electrical control connection is established. The hydraulic cylinder control button 17 activates the hydraulic cylinder 6, driving the particle extrusion plate 7 to move downwards autonomously, extruding the graphite particles within the mounting frame 10 to reduce particle size or optimize structure. At the same time, the first electric telescopic device control button 15 triggers the electric telescopic device 14, driving the pusher plate 13 towards the supporting frame plate 4. This initial pushing action ensures uniform particle distribution during extrusion, preventing localized accumulation and setting conditions for subsequent cleaning. A second electric telescopic device control button 16 is located on the side wall of the particle extrusion plate 7, serving as a secondary trigger element for pushing. When the pusher plate 13 moves toward the granule extrusion plate 7 under the drive of the electric telescoping device 14, its outer wall contacts and triggers the second electric telescoping device control button 16. Through the electrical control connection achieved by the conduction line, the second electric telescoping device control button 16 reactivates the electric telescoping device 14, causing it to drive the pusher plate 13 to move in the opposite direction, that is, to move away from the granule extrusion plate 7. The reverse pushing action cleans up the residual granules near the mounting frame plate 10, preparing for the next round of extrusion processing.

[0036] First, the extrusion assembly of hydraulic cylinder 6 and particle extrusion plate 7, in conjunction with the triggering mechanism of hydraulic cylinder control button 17, achieves particle size adjustment based on adaptive control of particle weight, reducing energy consumption and improving processing accuracy. Second, the pushing assembly of electric telescopic device 14 and pusher plate 13, through a dual triggering mechanism of first electric telescopic device control button 15 and second electric telescopic device control button 16, forms a dynamic cycle of initial pushing and reverse cleaning, ensuring the continuity and cleanliness of particle processing. Third, the device makes the graphite particles more uniform in size through extrusion processing, increasing the surface area and reactivity of the particles, providing raw material conditions for subsequent desulfurization and denitrification reactions (such as the chemical removal of sulfides and nitrogen oxides).

[0037] In one possible implementation, a drive motor 23 is provided at the bottom of the inner wall of the upper processing cavity 21, a rotating rod 24 is provided at the working end of the drive motor 23, the graphite particle processing assembly 1 is provided on the outer wall of the rotating rod 24, a bearing seat 25 is provided at the top of the inner wall of the upper processing cavity 21, and one end of the rotating rod 24 is provided inside the bearing seat 25.

[0038] In a specific application of this invention, the working end of the drive motor 23 is connected to the rotating rod 24, enabling the rotating rod 24 to achieve stable and high-speed rotation under the drive of the drive motor 23. The graphite particle processing component 1 is installed on the outer wall of the rotating rod 24, and the graphite particle processing component 1 rotates synchronously with the rotating rod 24, directly acting on the graphite particles in the upper processing chamber 21. The rotational motion disperses, grinds, or modifies the particles. A bearing seat 25 is provided at the top of the inner wall of the upper processing chamber 21, and one end of the rotating rod 24 is embedded in the bearing seat 25. The bearing seat 25 provides stable rotational support for the rotating rod 24, ensuring that the rotating rod 24 maintains axial stability during high-speed rotation, reducing vibration and energy loss, and extending the service life of the device. When graphite particles are fed into the upper processing chamber 21, the drive motor 23 starts and drives the rotating rod 24 to rotate inside the upper processing chamber 21 through its working end. The rotation of the rotating rod 24 causes the graphite particle processing component 1 on the outer wall to move synchronously. The graphite particle processing component 1 comes into dynamic contact with the particles in the chamber and drops the graphite particles into the interior of the limiting frame 2.

[0039] The upper processing chamber 21, as a closed processing space, effectively constrains the movement trajectory of graphite particles, preventing particle splashing or leakage, while providing a stable working environment for the particle processing assembly 1 and enhancing the uniformity of the processing effect. Secondly, the power transmission assembly between the drive motor 23 and the rotating rod 24 achieves energy conversion through mechanical connection, and combined with the supporting role of the bearing seat 25, improves the operational stability and energy efficiency of the device. Thirdly, the graphite particle processing assembly 1 dynamically processes the particles through rotational motion, effectively breaking up particle agglomerates and allowing some graphite particles to fall into the limiting frame 2 for further processing.

[0040] In one possible implementation, buffer damping rods 9 are provided at the four corners of the top surface of the fixed plate 8, and the top surfaces of the four buffer damping rods 9 are located at the bottom of the mounting frame 10; a particle placement plate 28 is provided at the bottom of the lower processing cavity 22, the particle placement plate 28 receives the processed graphite particles, and shock-absorbing damping rods 29 are provided at the four corners of the bottom surface of the particle placement plate 28.

[0041] In a specific application of this invention, the fixed plate 8 has four corners on its top surface equipped with buffer damping rods 9. The top of the buffer damping rods 9 is connected to the bottom of the mounting frame 10, forming a stable suspension support system. The mounting frame 10 serves as the external frame of the lower processing chamber 22. Through the elastic connection between the buffer damping rods 9 and the fixed plate 8, it can effectively absorb and disperse the vibration and impact forces generated during the operation of the device. The lower processing chamber 22 has a particle placement plate 28 inside, which serves as a receiving platform for the processed graphite particles. The four corners on the bottom surface of the particle placement plate 28 are equipped with shock-absorbing damping rods 29. The shock-absorbing damping rods 29 further reduce the vibration impact on the particle placement plate 28 during particle receiving or equipment operation through their damping characteristics, ensuring the smooth operation of the particle placement plate 28 and the stable collection of particles.

[0042] The particle placement plate 28 receives the processed graphite particles. Its flat receiving surface can evenly distribute the weight of the particles, preventing local accumulation or slippage. The damping rods 29 at the four corners of the bottom surface of the particle placement plate 28 absorb the impact force of the particles and the dynamic load caused by equipment vibration through elastic deformation and damping energy dissipation mechanism when the particles fall in or the equipment is running, maintaining the stability of the particle placement plate 28 and preventing the particles from being dispersed or broken due to vibration. At the same time, the fixing plate 8 is elastically connected to the mounting frame 10 through the buffer damping rods 9 at the four corners of its top surface. The buffer damping rods 9 use their damping characteristics to further reduce the vibration transmission of the lower processing cavity 22 and the mounting frame 10 as a whole, reducing the impact of vibration on the particle placement plate 28 and the receiving particles.

[0043] In one possible implementation, four discharge pipes 30 are provided on the outside of the working cylinder 18. One end of each discharge pipe 30 is located inside the lower processing chamber 22. Each discharge pipe 30 is equipped with a solenoid valve 31. A solenoid valve control button 32 is provided at the bottom of the particle placement plate 28. Graphite particles fall into the particle placement plate 28 and are pressed to contact the solenoid valve control button 32. The solenoid valve 31 is electrically connected to the solenoid valve control button 32 through a conduction line.

[0044] In this embodiment of the invention, four discharge pipes 30 are evenly distributed on the outer side of the working cylinder 18. One end of each discharge pipe 30 extends into the lower processing chamber 22, forming a channel for discharging graphite particles from the particle placement plate 28 to the external environment. Each discharge pipe 30 is equipped with a solenoid valve 31, which controls the on / off state of the discharge pipe 30 through its switching function, ensuring the accuracy and controllability of particle discharge. The particle placement plate 28 is located at the bottom of the lower processing chamber 22, serving as a receiving platform for the processed graphite particles. A solenoid valve control button 32 is located at its bottom, and the button is electrically connected to the four solenoid valves 31 via a conductive line, forming a trigger control system. When graphite particles fall into the particle placement plate 28 and accumulate to a certain weight, the plate sinks under pressure, triggering the solenoid valve control button 32. This, in turn, activates the solenoid valves 31 via an electrical signal, opening the discharge pipes 30 and achieving automated particle discharge.

[0045] The processed graphite particles fall into the particle placement plate 28 through the inlet of the lower processing chamber 22. The flat receiving surface of the particle placement plate 28 can evenly bear the weight of the particles, avoiding uneven particle accumulation or slippage. As the particles continue to accumulate, the pressure on the particle placement plate 28 gradually increases. When the pressure reaches a certain threshold, the particle placement plate 28 experiences a slight sinking, triggering the solenoid valve control button 32 at the bottom. The solenoid valve control button 32, acting as a pressure-sensing trigger element, immediately sends an electrical signal to the four solenoid valves 31 through the conduction wire. Upon receiving the signal, the solenoid valves 31 quickly open, unblocking the discharge pipe 30. The graphite particles on the particle placement plate 28 are discharged through the four discharge pipes 30 to an external collection device or subsequent processing unit. After discharge, the weight of the particles on the particle placement plate 28 decreases, the pressure decreases, the solenoid valve control button 32 returns to its initial state, cutting off the electrical signal, the solenoid valves 31 close, and the discharge pipe 30 stops discharging, awaiting the next round of particle accumulation and triggering.

[0046] In one possible implementation, a gas purifier 33 is provided at the top of the working cylinder 18, and a gas delivery pipe 34 is provided at the working end of the gas purifier 33. The other end of the gas delivery pipe 34 is located inside the upper processing chamber 21 to purify the gas during the processing of graphite particles.

[0047] In a specific application of this invention, a gas purifier 33 is fixedly installed on the top of the working cylinder 18. The gas purifier 33 has purification capabilities such as adsorption, catalysis, or chemical reaction, and can effectively remove sulfides, nitrogen oxides, and other harmful components from the waste gas. The working end of the gas purifier 33 is connected to a gas delivery pipe 34, which serves as a dedicated channel for waste gas transmission. One end of the gas delivery pipe 34 is tightly connected to the working end of the gas purifier 33, and the other end extends into the interior of the upper processing chamber 21, forming a directional airflow path from the processing chamber to the purifier. The upper processing chamber 21 serves as the working area for the preliminary treatment of graphite particles. The waste gas generated during the operation is efficiently transported to the gas purifier 33 for treatment through the gas delivery pipe 34. The purified clean gas is released to the external environment or subsequent treatment system through the exhaust end of the gas purifier 33.

[0048] During the graphite particle processing, the processing operations within the upper processing chamber 21 generate waste gas containing pollutants such as sulfides and nitrogen oxides. This waste gas accumulates within the chamber, creating a pressure difference that causes it to flow upwards along the gas delivery pipe 34. The gas delivery pipe 34 extends into the end of the upper processing chamber 21, ensuring efficient capture and directional transport of the waste gas, preventing stagnation or disorderly diffusion within the chamber. After entering the working end of the gas purifier 33 through the gas delivery pipe 34, the gas purifier 33 immediately activates its internal purification mechanism (such as activated carbon adsorption, catalyst conversion, or chemical neutralization reaction) to decompose, adsorb, or convert the harmful components in the waste gas. The purified gas meets environmental emission standards and is discharged orderly through the exhaust port of the gas purifier 33, completing the entire gas purification process.

[0049] In one possible implementation, a graphite particle inlet is provided on the outside of the working cylinder 18, and a remote controller is provided on the outside of the working cylinder 18. The remote controller is electrically connected to the electric hydraulic cylinder 6, the electric telescopic device 14 and the solenoid valve 31 through a transmission line. The bottom surface of the working cylinder 18 is provided with two support columns 19, and the bottom surface of each support column 19 is provided with a protective plate 20. The bottom surface of the two protective plates 20 is provided with anti-slip texture.

[0050] In a specific application of this invention, a remote controller configured outside the working cylinder 18 establishes an electrical control connection with the electric hydraulic cylinder 6, the electric telescopic device 14, and the solenoid valve 31 via a transmission line, forming a centralized control network. As the intelligent hub of the system, the remote controller can receive operation commands in real time and precisely control the thrust output of the electric hydraulic cylinder 6, the extension and retraction range of the electric telescopic device 14, and the opening and closing state of the solenoid valve 31, thereby achieving precise control of material conveying, process adjustment, and gas / liquid flow during graphite production.

[0051] Two support columns 19 on the bottom surface of the working cylinder 18 provide physical support for the device. The protective plate 20 connected to the bottom surface of the support column 19 further enhances the stability of the support structure. The anti-slip texture designed on the bottom surface of the protective plate 20 increases the friction with the ground, effectively preventing the device from slipping or tipping over due to vibration or external force during operation.
