Description

Technical Field

[0001] This utility model relates to the field of crushing pitch coke raw materials with high pressure resistant graphite, and more specifically, to a crushing device for pitch coke raw materials with high pressure resistant graphite. Background Technology

[0002] Pitch coke is a type of coke produced by coking coal tar pitch at high temperatures. Initially, the pitch coke raw material has varying particle sizes. For the production of high-pressure resistant graphite, the pitch coke needs to be crushed into suitable particle sizes to ensure uniform distribution of the raw material during subsequent mixing and molding processes. The carbon content of pitch coke is typically around 90%-95%. In the preparation of high-pressure resistant graphite, this high carbon content helps form the graphite's crystal structure. The carbon atoms in the graphite crystal structure are bonded by covalent bonds to form a hexagonal planar network structure. This structure allows for relative sliding between layers and possesses good electrical and thermal conductivity. The high carbon content of the pitch coke provides the foundation for these excellent properties of graphite, enabling the prepared graphite to maintain good stability under high pressure.

[0003] In existing technologies, when crushing asphalt coke raw materials, the filter plate size of the existing crushers is relatively fixed. When it is necessary to change the production plan to produce asphalt coke raw materials of different particle sizes, the fixed filter plate size may not be able to be adjusted according to the actual situation of the asphalt coke raw materials. When switching from producing larger particle size asphalt coke products to producing smaller particle size products, it may be necessary to replace the crusher or make complex modifications to the filter plate of the crusher. This will reduce production efficiency and increase production costs. Therefore, we propose a high-pressure graphite-resistant asphalt coke raw material crushing device to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example 1:

[0029] Please see Figure 1 - Figure 5A high-pressure graphite-resistant asphalt coke raw material crushing device includes a base 1, a crusher 2, a feed inlet 3, and a discharge outlet 4. The crusher 2 is fixedly connected to the surface of the base 1. The feed inlet 3 and the discharge outlet 4 are both located on the surface of the crusher 2. A filter plate 5 is fixedly connected to the inner wall of the crusher 2. An adjustment structure 6 is provided on the surface of the filter plate 5. The adjustment structure 6 includes several grooves 601, all of which are located on the surface of the filter plate 5. An adjustment plate 602 is slidably connected to the inner wall of the grooves 601. Two connecting rods 603 are slidably inserted into the surface of the filter plate 5. The adjustment plates 602 are fixedly connected to the two connecting rods 603. One end of the connecting rod 603 slides through the crusher 2. A drive plate 604 is fixedly connected to one end of the two connecting rods 603. A threaded rod 605 is threaded through the surface of the drive plate 604. The threaded rod 605 is rotatably connected to the surface of the crusher 2. Two fixed columns 608 are fixedly connected to the side of the crusher 2 near the drive plate 604. The length of the two fixed columns 608 is the same as the width of the filter holes on the surface of the filter plate 5. A movable plate 607 is slidably connected to the surface of the two fixed columns 608. An extension plate 606 is fixedly connected to the side of the movable plate 607 near the drive plate 604, and the extension plate 606 is fixedly connected to the drive plate 604. Several scale marks 609 are evenly distributed on the surface of the fixed columns 608. A circular plate 610 is fixedly connected to the end of the threaded rod 605 away from the crusher 2. Several rotating rods 611 are fixedly connected to the arc surface of the circular plate 610.

[0030] Please see Figure 1 and Figure 6 A high-pressure graphite-resistant pitch coke raw material crushing device includes a shielding structure 7 on the inner wall of the feed inlet 3. The shielding structure 7 includes a support 71, which is fixedly connected to the inner wall of the feed inlet 3. A baffle 72 is rotatably connected to the surface of the support 71. Two round rods 73 are slidably inserted into the surface of the crusher 2. Springs 74 are sleeved on the arc surface of the round rods 73, and the two ends of the springs 74 are fixedly connected to the round rods 73 and the crusher 2, respectively. An arc-shaped groove is opened at the end of the round rod 73 near the baffle 72, and a rotating plate 75 is rotatably connected to the inner wall of the arc-shaped groove. Several rectangular grooves 76 are opened on the surface of the baffle 72.

[0031] Working principle: When it is necessary to adjust the filter hole size of filter plate 5, first rotate the rotating rod 611. The rotation of the rotating rod 611 will drive the circular plate 610 to rotate. The rotation of the circular plate 610 will drive the threaded rod 605 to rotate on the surface of the crusher 2. The rotation of the threaded rod 605 will drive the drive plate 604 to move closer to the crusher 2 through the thread. The movement of the drive plate 604 will drive the two connecting rods 603 to slide inside the crusher 2. The movement of the connecting rods 603 will simultaneously drive several adjusting plates 602 to gradually slide out of the grooves 601. At the same time, the movement of the drive plate 604 will drive the extension plate 606 to move. The movement of the extension plate 606 will drive the moving plate 607. As the moving plate 607 slides along the surface of the fixed column 608, it gradually moves closer to the crusher 2. Since the length of the fixed column 608 is the same as the width of the filter holes on the surface of the filter plate 5, the width of the blocked filter holes can be easily determined by observing the position of the moving plate 607. When the moving plate 607 moves to the appropriate position, the threaded rod 605 is rotated to move the adjusting plate 602 to the appropriate position. The adjusting plate 602 can block the size of the filter holes to an appropriate size. The scale marks 609 on the surface of the fixed column 608 can be used to determine the specific size of the unblocked filter holes, thus making it easier to control the particle size of the crushed asphalt coke.

[0032] When crushing asphalt coke raw materials using crusher 2, the asphalt coke raw materials are first fed into the feed inlet 3. After entering the feed inlet 3, the asphalt coke raw materials will slide along the inner wall of the feed inlet 3. At this time, smaller pieces of asphalt coke raw materials will slide into the crusher 2 through the rectangular groove 76 opened on the surface of the baffle 72. Larger pieces of asphalt coke raw materials will squeeze the baffle 72 during the sliding process. The rectangular groove facilitates the direct entry of smaller pieces of asphalt coke raw materials into the crusher 2 for crushing, thereby improving the crushing efficiency of the asphalt coke raw materials. The baffle 72 will rotate within the support 71 due to the compression of the asphalt coke raw materials. The rotation of the baffle 72 will squeeze... The pressure rod 73, when compressed, gradually detaches from the crusher 2 and drives the rotating plate 75 to slide along the surface of the baffle 72. The movement of the rod 73 stretches the spring 74, and the rotating plate 75 reduces the friction when the rod 73 slides along the surface of the baffle 72, thus facilitating the rotation of the baffle 72. When the baffle 72 rotates to a suitable angle, the asphalt coke raw material enters the crusher 2 from the feed inlet 3 for crushing. By using the baffle 72 to block the inner wall of the feed inlet 3, the asphalt coke raw material is prevented from splashing out from the feed inlet 3 during crushing.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
