Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing and grinding, and more specifically to a graphite processing and grinding device capable of preventing graphite dust from leaking out. Background Art

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid with stable chemical properties, corrosion resistance, and low reactivity with acids and alkalis. Natural graphite comes from graphite deposits, but it can also be made from petroleum coke, asphalt coke, and other raw materials through a series of processing steps to produce artificial graphite. Graphite burns in oxygen to produce carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It is used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in nuclear reactors. It is also used in the manufacture of crucibles, electrodes, brushes, dry cell batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, and pencil refills.

[0003] Patent authorization number CN212681153U discloses a grinding device for processing graphene heat dissipation film, which includes a box body, a crushing mechanism is provided on the upper part of the box body, a progressive grinding mechanism is provided below the crushing mechanism, and a deep grinding mechanism is provided below the progressive grinding mechanism. The raw materials are initially crushed by a crushing cylinder, and then further refined by staggered teeth. Then, they are deeply crushed by a multi-stage grinding plate group with different gaps, so that the material falls into the interior of the grinding chamber. The servo motor drives the grinding block to grind the material inside the grinding chamber back and forth, so that the qualified ground material continuously falls through the mesh. At the same time, the gap between the grinding block and the grinding chamber can be adjusted by an electric telescopic rod, which is convenient for adjusting the grinding force. The structural design is relatively reasonable, the multi-stage grinding effect is better, and there is no need for secondary screening. The grinding efficiency is high, which is easy to promote and use.

[0004] However, the top opening of the feeding hopper in patent authorization number CN212681153U is set in an open structure. Therefore, during the graphite grinding process, graphite dust often leaks out, causing environmental pollution. The powder will affect the health of the workers after being inhaled. At the same time, the dust will also lead to the loss of raw materials. Therefore, we propose a graphite processing grinding device that prevents the leakage of graphite dust to solve the above-mentioned problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

A corrugated hose 10 is conductively connected between the sealing cover 9 and the air outlet end of the industrial dust suction fan 7. A pressure relief hole 11 is opened on the edge of the sealing cover 9;

[0032] A slotted hole 13 is provided on the side wall of the grinding box 1 below the suction hood 3. A baffle 14 is slidably connected to the inner side of the slotted hole 13. A mounting bracket 15 fixedly connected to the outer wall of the feeding bin 2 is provided below the slotted hole 13. A telescopic cylinder 16 with a movable end drivingly connected to the baffle 14 is installed at the end of the mounting bracket 15 away from the feeding bin 2.

[0033] It should be noted that when the graphite processing grinding device for preventing graphite dust from leaking is used, an appropriate amount of graphite raw material is added to the feeding bin 2, and the graphite raw material enters the grinding box 1 for grinding;

[0034] In the process of continuously adding graphite raw materials, by turning on the industrial dust suction fan 7, when the graphite powder generated in the grinding process is raised through the top of the feeding bin 2, the raised powder is sucked by the suction hood 3 and transported by the connecting pipe 4. Finally, the powder is transported to the storage tank 8 through the corrugated hose 10, and the pressure balance in the storage tank 8 is ensured by the pressure relief hole 11. The collected graphite powder can be used by removing the sealing cover 9, which reduces the loss of raw materials and avoids the pollution of the environment by the raised graphite powder, while providing a good working environment for the staff.

[0035] The telescopic cylinder 16 is connected to an external pneumatic control device, and the pneumatic control device is used to control the extension and retraction of the movable end of the telescopic cylinder 16. After the addition of the graphite raw material is completed, the movable end of the telescopic cylinder 16 is extended, so that the baffle 14 slides inside the straight hole 13, and then the baffle 14 closes the top opening of the feeding bin 2, preventing graphite dust from being blown out, which can further reduce the loss of graphite raw material during grinding.

[0036] like Figure 3 As shown, the inner side of the pressure relief hole 11 is filled with filter cotton 12;

[0037] It should be noted that by filling the filter cotton 12 inside the pressure relief hole 11 , the graphite powder can be trapped while ensuring air permeability, thereby preventing it from being blown out of the pressure relief hole 11 .

A limit portion is provided at one end of the baffle 14 close to the mounting bracket 15, and the limit portion is connected to the movable end of the telescopic cylinder 16. The displacement length of the movable end of the telescopic cylinder 16 is greater than the displacement length of the baffle 14.

[0041] It should be noted that the stability of the baffle 14 in the process of movement when cooperating with the slotted hole 13 is ensured, and at the same time, the baffle 14 is ensured to be able to close the top opening of the feeding bin 2 after merging.

[0042] like Figure 1 As shown, a through hole is provided at the joint between the feeding bin 2 and the connecting pipe 4, and the inner diameter of the through hole is adapted to the outer diameter of the connecting pipe 4;

[0043] It should be noted that the stability of the assembly of the connecting pipe 4 and the through hole is ensured.

[0044] When in use: add an appropriate amount of graphite raw material to the feeding bin 2, and allow the graphite raw material to enter the grinding box 1 for grinding;

[0045] During the continuous addition of graphite raw materials, the industrial dust suction fan 7 is turned on. When the graphite powder generated during the grinding process is raised through the top of the feeding bin 2, the raised powder is sucked by the suction hood 3 and transported by the connecting pipe 4. Finally, the powder is transported to the storage tank 8 through the corrugated hose 10, and the pressure balance in the storage tank 8 is ensured by the pressure relief hole 11. The collected graphite powder can be used by removing the sealing cover 9;

[0046] The telescopic cylinder 16 is connected to an external pneumatic control device, and the pneumatic control device is used to control the extension and retraction of the movable end of the telescopic cylinder 16. After the addition of the graphite raw material is completed, the movable end of the telescopic cylinder 16 is extended, causing the baffle 14 to slide inside the straight hole 13, thereby causing the baffle 14 to close the top opening of the feeding bin 2.

[0047] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
