Description

Technical Field

[0001] This utility model relates to the field of artificial graphite anode materials, and in particular to a multi-stage cooling, filtering and screening mechanism for graphitized insulation materials. Background Technology

[0002] In existing technologies, graphitized insulating material serves as insulation and electrical insulation in graphitization furnaces. Traditionally, the graphitization furnace undergoes a heating-holding-cooling process. During this process, the material temperature inside the furnace reaches as high as 3000℃, requiring temperature reduction to continue production. The natural cooling rate over time follows an inverse proportional function curve, meaning the cooling rate slows down with increasing time. The traditional method involves first allowing natural cooling, then using a suction crane to transfer the material to a slag cooler for further cooling, followed by screening to separate coarse and fine particles for recycling. This process is complex, time-consuming, inefficient, and costly. Utility Model Content

These methods are characterized by numerous steps, long processing times, low efficiency, and high costs.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0005] A multi-stage cooling and filtration screening mechanism for graphitized insulation materials includes a filter, a chamber located at the bottom of the filter, filter screens for filtering particles, a pipe located on the filter, a water-cooled jacket for cooling the material inside the pipe, a baffle hinged to the bottom of the chamber, a fan for exhaust, and a high-temperature resistant filter element to prevent high-temperature materials from flowing into the fan. The chamber array consists of three groups; the three groups of chambers sequentially discharge coarse particles, medium particles, and fine particles; the chambers are connected to the filter; the filter screen array consists of several groups, with the coarse filter screen located above the chamber containing coarse particles, the medium filter screen located above the chamber containing medium particles, and the fine filter screen located above the chamber containing fine particles; the high-temperature resistant filter element is located at the air inlet of the fan.

[0006] As a further improvement to the above technical solution: the filter is provided with a deceleration zone; the deceleration zone is funnel-shaped; the deceleration zone is connected to the pipe body.

[0007] As a further improvement to the above technical solution: a counterweight is provided on the baffle; the counterweight restricts the baffle from always sealing the bottom of the chamber.

[0008] As a further improvement to the above technical solution: the high-temperature resistant filter element can withstand a working temperature of ≥1000℃.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0010] 1. High-temperature materials are drawn into a multi-stage filter using high-speed airflow. They undergo progressive cooling, deceleration, and separation through a deceleration zone, screens, and high-temperature filter elements, achieving simultaneous cooling and separation. The filter contains seven sets of screens and one set of high-temperature filter elements, allowing for the replacement of different mesh sizes to meet varying particle size requirements. This saves costs, simplifies operation, and reduces expenses. The working process is as follows: 1. The negative pressure fan starts. 2. The discharge port baffle closes due to negative pressure. 3. High-temperature material enters the filter, simultaneously cooling and separating according to particle size. 4. After a period of time, the negative pressure fan shuts off. 5. Due to the material's own weight, the discharge baffle opens. 6. The screened material enters the buffer hopper, completing the screening and cooling process. Attached Figure Description
