Description

Technical Field

[0001] This utility model pertains to tank-type calcining furnace devices, specifically relating to a furnace cover device for an assembled tank-type calcining furnace. Background Technology

[0002] The petroleum coke calciner is the core equipment in the petroleum coke calcination process. Its main function is to process raw petroleum coke (Green Petroleum Coke) under high temperature (usually 1200℃-1500℃) and air-isolated conditions to remove volatiles and moisture, and improve its true density, mechanical strength, electrical conductivity, and chemical stability, making it calcined petroleum coke that meets the production requirements of electrolytic aluminum, graphite electrodes, and carbon raisers. There are two main types of calciners: pot-type calciners and rotary kilns. The pot-type calciner mainly consists of a furnace body composed of multiple vertically arranged calcining pots, typically constructed of refractory bricks. The number of pots is determined by production capacity requirements (commonly 24, 32, 36, or 40 pots). The raw coke moves from top to bottom within the calciner to complete the calcination process. A feeding system is installed at the top of the calcining furnace, typically including a hopper, a feeder (such as an electromagnetic vibrating feeder or a star feeder), and a sealing device. This system quantitatively, uniformly, and in a sealed manner adds raw coke to the top of each calcining furnace. The pot-type calcining furnace provides a high-temperature, sealed environment for the raw coke to calcine. Existing pot-type calcining furnaces have a sealed furnace cover structure at the top of the pot. However, due to the frequent filling of raw coke and the heavy weight of the furnace cover structure, its assembly with the furnace body is time-consuming and labor-intensive, hindering the efficient operation of the pot-type calcining furnace.

Figures 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figures 1-4 As shown, this utility model discloses a furnace cover device for an assembled tank-type calcining furnace. The furnace cover device 100 includes a cover body 1, a supporting base beam 6, a lifting crossbeam 9, a guide beam 12, and a guide frame 15. A cover retaining ring 17 is arranged circumferentially along the outer edge of the cover body 1. The supporting base beam 6 includes two beams symmetrically arranged along the diameter of the cover 1, and each supporting base beam 6 has a hinge groove 7 at both ends. The lifting beam 9 is arranged above the supporting base beam 6 along the center line of the two supporting base beams 6, and each end of the lifting beam 9 has a hinge lug 10 corresponding to the supporting base beam 6. Each hinge lug 10 and the corresponding hinge groove 7 are connected by a hinge connecting rod 8, that is, the lifting beam 9 is hinged to both ends of the two supporting base beams 6 through four hinge connecting rods 8. Lifting lugs 11 are provided at both ends of the lifting beam 9, and the lifting lugs 11 can be used by the electric hoist or overhead crane in the workshop for suspension and lifting, thereby realizing the overall lifting or lowering of the furnace cover device 100. The guide beam 12 includes two beams that are vertically connected to the outer ends of the corresponding supporting base beam 6 along the center line of the supporting base beam 6, and each guide beam 12 has a guide column 13 vertically connected to its outer end, that is, the guide beam 12 and the lifting beam 9 are in the same plane in the vertical direction. The guide frame 15 includes two guide frames respectively disposed at the outer ends of the guide beam 12. Each guide frame 15 is provided with a guide groove 16 for sliding connection of the guide column 13 along the vertical direction. The guide frame 15 can be disposed on a fixed frame or wall in the workshop corresponding to the guide beam 12, serving as a guide structure for the furnace cover device 100. When the furnace cover device is installed, the guide column 13 of the guide beam 12 is positioned and locked in the guide groove 16 of the guide frame 15 to achieve precise positioning of the furnace cover device and thus improve assembly efficiency.

[0025] In a preferred embodiment, such as Figure 1 As shown, a support beam 5 is provided parallel to the inner side of each support base beam 6, and one end of the guide beam 12 extends to the support beam 5 and is fixedly connected to the support beam 5. That is, each guide beam 12 is welded or bolted to the corresponding support base beam 6 and support beam 5, thereby improving the connection strength between the guide beam 12 and the cover 1.

[0026] In a preferred embodiment, such as Figure 1 As shown, the upper and lower sides of the guide beam 12 are respectively provided with reinforcing plates 14 that are fixed to the outer sidewall of the guide column 13. This structure can strengthen the connection between the guide beam 12 and the guide column 13.

A water seal cover plate 2 is provided on the outer circumference of the cover 1, and a water seal retaining ring 18 is provided on the outer circumference of the water seal cover plate 2 and the cover retaining ring 17, forming a water seal groove 19 between the water seal retaining ring 18 and the cover retaining ring 17. It should be noted that the outer diameter of the cover retaining ring 17 is smaller than the inner diameter of the inner wall of the water seal storage tank 21, and the diameter of the water seal retaining ring 18 is larger than the inner diameter of the inner wall of the water seal storage tank 21 and smaller than the outer inner diameter of the water seal storage tank 21. This structure allows the water seal groove 19 to be misaligned and engaged in the water seal storage tank 21, thereby forming a water seal inside and outside the water seal retaining ring 18, thus improving the sealing effect inside the tank-type calcining furnace.

[0028] In a preferred embodiment, such as Figure 1 As shown, the water seal cover plate 2 and the water seal retaining ring 18 are respectively provided with vertically arranged reinforcing ribs 3 along their circumference. The reinforcing ribs 3 can enhance the structural strength of the water seal cover plate 2 and the water seal retaining ring 18.
