Description

Technical Field

[0001] The utility model belongs to the technical field of graphitization processing, and in particular relates to a crucible cover conveying device and a crucible cover installing and removing system. Background Art

[0002] Graphitization refers to the process of heating non-graphite carbon to above 2000°C in a protective medium in a high-temperature electric furnace or in an airtight state. Due to physical changes, the hexagonal carbon atom plane mesh layer stacking structure is improved and developed, and the product is transformed into graphite carbon with a three-dimensional regular and orderly structure of graphite. Graphitization improves the product's volume density, electrical conductivity, thermal conductivity, corrosion resistance and mechanical processing performance. Graphitization is a key process in the production of artificial graphite negative electrodes.

[0003] In the workshop for graphitizing non-graphite carbon, there are multiple processes, including the steps of loading non-graphite carbon powder into a crucible, covering the crucible with a lid, sending the loaded crucible into a graphitization furnace, taking the fired crucible out of the graphitization furnace, removing the lid of the crucible, pouring out the graphitized material in the crucible, and the like.

[0004] Among them, in the step of covering the crucible cover on the crucible or in the step of removing the crucible cover from the crucible, if it is operated manually, not only the efficiency is low and the workload is large, but also the dust generated by the powder material is harmful to the health of the operator.

Figure 1-3 and Figure 5 As shown, the crucible lid installation and removal system includes the crucible lid transfer device described in any of the previous embodiments, and also includes a crucible positioning device. The crucible positioning device includes a crucible conveying mechanism 1. The crucible conveying mechanism 1 is used to convey the crucible 2 to a corresponding position so that a lid can be installed on the top of the crucible 2 or the lid on the top of the crucible 2 can be removed by the crucible lid moving mechanism.

A telescopic driving component is provided on the stand 121, and two positioning claws 122 are provided at the front end of the telescopic driving component. The telescopic driving component is used to drive the positioning claws 122 to move forward and backward.

[0032] The working method of the crucible positioning device is as follows: the crucible 2 is conveyed to the side of the retaining frame 11 by the crucible conveying mechanism 1, and the telescopic driving component on the stand 121 drives the two positioning claws 122 to extend forward, so that the positioning claws 122 contact the outer wall of the crucible 2, and the two positioning claws 122 are spaced apart from each other and abut against the outer wall of the crucible 2, and the crucible 2 is pushed forward and leans against the retaining frame 11. In this way, the crucible 2 is clamped between the retaining frame 11 and the two positioning claws 122 and positioned, so that the crucible cover transfer device can cover the crucible 2 with a cover, or remove the cover from the crucible 2.

[0033] Further, in one embodiment, if Figure 3As shown, the telescopic drive component includes a second telescopic cylinder 123 in the middle and second guide rods 124 on both sides thereof, a second sleeve 125 corresponding to the second guide rod 124 is provided on the stand 121, the cylinder barrel of the second telescopic cylinder 123 is mounted on the stand 121, the second guide rods 124 on both sides are mounted in the corresponding second sleeves 125, a mounting plate 126 is provided at the front ends of the telescopic cylinder 123 and the second guide rod 124, and two positioning claws 122 are provided at both ends of the front side of the mounting plate 126.

Since two crucible conveying mechanisms 1 are arranged, the crucible positioning device has two working stations, which improves efficiency.

[0035] The crucible lidding and uncapping system works as follows:

[0036] (1) When the crucible cover 4 needs to be installed on the crucible 2: the crucible 2 is transported to an appropriate position and positioned by the crucible positioning device; the trolley driving mechanism of the crucible cover transporting device drives the moving trolley 51 to move along the trolley track 5, so that the moving trolley 51 is directly above the crucible cover 4, the cover removal suction cup 6 is attached to the top crucible cover 4, and the negative pressure system is used to apply negative pressure to the cover removal suction cup 6. The cover removal suction cup 6 sucks the top crucible cover 4, and the trolley driving mechanism drives the moving trolley 51 to move along the trolley track 5, so that the moving trolley 51 is directly above the crucible 2. During this process, the cover removal suction cup 6 carries the crucible cover 4 to the top of the crucible 2, and the negative pressure system connected to the cover removal suction cup 6 stops negative pressure adsorption, releasing the crucible cover 4 from covering the crucible 2. (2) When it is necessary to remove the crucible cover on the crucible 2: the crucible 2 is transported to an appropriate position and positioned by the crucible positioning device; the trolley driving mechanism in the crucible cover transporting device drives the moving trolley 51 to move along the trolley track 5, so that the moving trolley 51 is directly above the crucible 2, and the cover removal suction cup 6 is attached to the crucible cover on the top of the crucible 2. The negative pressure system draws negative pressure on the cover removal suction cup 6, and the cover removal suction cup 6 sucks the crucible cover on the top of the crucible 2. The moving trolley 51 is driven by the trolley driving mechanism to move along the trolley track 5, so that the cover removal suction cup 6 under the moving trolley 51 carries the crucible cover to the position directly above the stacking crucible cover (lifting plate 41), and the negative pressure system connected to the cover removal suction cup 6 stops negative pressure adsorption, and the crucible cover is released and stacked together with the crucible cover on the lifting plate 41.
