[0022] Embodiment:

[0023] The embodiment of the present utility model provides an environment-friendly graphite production dust collection and treatment device, which can use the principle of negative pressure to suck the dust in the graphite granulation production equipment into the interior of the graphite dust treatment box 1, and achieve efficient dust filtration through the high-efficiency dust filtration group to ensure that the emissions meet the environmental protection standards, thereby realizing environmental protection and preventing damage to the human body, so as to solve the problems raised in the above background technology;

[0024] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0025] The environment-friendly graphite production dust collection and treatment device includes a graphite dust treatment box 1 for graphite production equipment. One side of the outer surface of the graphite dust treatment box 1 near the bottom end is fixedly installed with a suction concentration box 11. The suction concentration box 11 is connected to the graphite production equipment through a plurality of groups of graphite production dust suction pipes 12. The bottom end of the graphite dust treatment box 1 is fixedly installed with a collection hopper 2. The bottom end of the collection hopper 2 is provided with an ash discharge valve 21. Through the suction concentration box 11 and a plurality of groups of graphite production dust suction pipes 12, the graphite dust treatment box 1 can be connected to each production cavity of graphite raw material mixing, crushing, stirring, and granulation, and at the same time, the dust collection and treatment measures for each production and processing link of graphite can be realized, which is more energy-saving and environmentally friendly. And the ash discharge valve 21 is provided to facilitate the export of the graphite dust inside the collection hopper 2;

[0026] Inside the graphite dust treatment box 1, a high-efficiency dust filtration group 4 is fixedly installed through an installation component 3. A backwashing component 5 is arranged at the top of the high-efficiency dust filtration group 4. One side of the outer surface of the graphite dust treatment box 1 near the top is connected in a through manner with an external high-pressure suction fan 7 through an air suction pipe 6. The top end of the graphite dust treatment box 1 is fixedly installed with a sealed box cover 9 through a fixing bolt 8. When the high-pressure suction fan 7 operates, under the action of negative pressure, the air containing a large amount of graphite dust inside the graphite production equipment sequentially passes through the graphite production dust suction pipe 12 and enters the inside of the graphite dust treatment box 1 through the suction concentration box 11, and dust filtration is achieved through the high-efficiency dust filtration group 4. The air after dust filtration will pass through the air suction pipe 6 and is finally discharged by the high-pressure suction fan 7. The filtered graphite dust will be collected inside the graphite dust treatment box 1 to ensure that the emissions meet the environmental protection standards, thereby realizing environmental protection and preventing damage to the human body;

[0027] Among them, the installation component 3 includes a fixed top plate 31 fixedly installed on the top surface of the high-efficiency dust filtration group 4, mounting seats 32 fixedly installed around the inner wall of the graphite dust treatment box 1, and fixing nuts 33. There are several groups of mounting seats 32, and several groups of mounting seats 32 are distributed in a ring shape. The top surface of the mounting seat 32 is fixedly installed with a mounting screw 34 adapted to the fixing nut 33. The high-efficiency dust filtration group 4 is composed of several groups of dust filters 41. End seats 42 are fixedly installed at the upper and lower ends of any one of the several groups of dust filters 41. The fixed top plate 31 is provided with clean air holes 311 and installation through holes 312 corresponding to the several groups of dust filters 41 and the mounting screws 34. The mounting screws 34 pass through the inside of the installation through holes 312, and the fixing nuts 33 are screwed on the outer surface of the mounting screws 34 near the top end. Through the design of the installation component 3, it is convenient to disassemble and assemble the high-efficiency dust filtration group 4. During installation, the fixed top plate 31 is introduced into the inside of the graphite dust treatment box 1, and the mounting screws 34 are made to pass through the inside of the installation through holes 312. At the same time, the fixing nuts 33 are screwed on the outer surface of the mounting screws 34 near the top end. Conversely, disassembly can be achieved. And through the provided clean air holes 311 corresponding to the several groups of dust filters 41, it is convenient to export the treated air, and the graphite dust will be retained on the outer surface of the dust filter 41, thereby realizing graphite dust filtration;

[0028] Among them, the recoil assembly 5 includes a base 51, several groups of recoil nozzles 52 and a solenoid valve 53. The base 51 is fixedly installed on the bottom surface of the sealed box cover 9. The several groups of recoil nozzles 52 correspond to the several groups of dust filters 41. The several groups of recoil nozzles 52 are fixedly installed on the bottom surface of the base 51. The solenoid valve 53 is fixedly installed on the top surface of the sealed box cover 9. An air passage 511 is arranged inside the base 51. The several groups of recoil nozzles 52 and the solenoid valve 53 are connected through the air passage 511. The solenoid valve 53 is connected to an external high-pressure compressed air source through a compressed air source pipe 531. Through the design of the recoil assembly 5, the graphite dust remaining on the outer surface of the dust filter 41 can be cleaned to avoid blockage and affect the filtration treatment of graphite dust. During backwashing, the solenoid valve 53 is opened. At this time, the external high-pressure compressed air source sequentially passes through the compressed air source pipe 531, the solenoid valve 53, and the air passage 511, and finally is led out by the several groups of recoil nozzles 52 corresponding to the several groups of dust filters 41 into the inside of the dust filter 41. At this time, under the action of the high-pressure gas, the graphite dust remaining on the outer surface of the dust filter 41 is cleaned and falls into the inside of the collection hopper 2, and then can be cleaned and led out through the ash discharge valve 21;

[0029] In addition, in this embodiment, please refer to Figure 1 , the solenoid valve 53 is electrically connected to an external PLC controller 532 through a wire, and through the design of the PLC controller 532, the solenoid valve 53 can be opened regularly for backwashing, which is convenient for management;

[0030] It should be particularly noted here that the solenoid valve, the PLC controller, and the high-pressure suction fan are all prior arts, and no more details will be described here.

[0031] In this embodiment, the implementation scenario is specifically as follows: First, several groups of graphite production dust suction pipes 12 are connected through to the respective production cavities of graphite raw material mixing, crushing, stirring, and granulation. Then, the high-pressure suction fan 7 is started to operate. At this time, under the action of negative pressure, the air containing a large amount of graphite dust inside the graphite production equipment sequentially passes through the graphite production dust suction pipes 12, the suction concentration box 11 and enters the inside of the graphite dust treatment box 1, and passes through the high-efficiency dust filtration group 4 to achieve dust filtration. The air after dust filtration will pass through the air suction pipe 6 and finally be discharged by the high-pressure suction fan 7. At the same time, the graphite dust will remain on the outer surface of the dust filter 41 to ensure that the emission meets the environmental protection standards, thereby achieving environmental protection and preventing damage to the human body.
