Description
Technical Field
The invention belongs to the technical field of calcium carbide production, and particularly relates to a chain belt type calcium carbide granulation waste heat recovery system.
Background
At present, in the process of smelting calcium carbide in a calcium carbide furnace, high-temperature calcium carbide liquid with the temperature of 1700-2100 ℃ is generated. After the high-temperature calcium carbide liquid flows from the calcium carbide furnace to the cast steel calcium carbide pot, the high-temperature calcium carbide liquid is firstly conveyed to a cooling factory by a rail car, naturally ventilated to 500-600 ℃, then, calcium carbide ingots weighing about 1 ton are lifted out by a large lifting hook, naturally ventilated to below 100 ℃, and then conveyed to a crushing workshop for coarse crushing and fine crushing, so that the calcium carbide particles conforming to the size are prepared for standby. In the calcium carbide liquid granulating process, the cooling speed of the large-block calcium carbide ingot is slower, the cooling time is longer, and the large-area site is occupied and the heat loss is serious.
The chinese patent with application number 201310304713.2 discloses a method for fast forming and waste heat recovery of high-temperature liquid calcium carbide by a chain belt type granulator, wherein the high-temperature liquid calcium carbide discharged from a calcium carbide furnace is directly placed on a conveying belt of the chain belt type granulator, a plurality of calcium carbide dies 122 and calcium carbide scrapers are arranged on the conveying belt, and the conveying chain belt is in reciprocating operation around a driving wheel and a driven wheel.
The calcium carbide mould with a split structure is adopted in the patent and consists of two identical half-block moulds which are arranged in a back-to-back manner; meanwhile, the high-temperature liquid calcium carbide in the calcium carbide die is cooled into solid calcium carbide blocks through continuous transmission of the conveying chain belt, and the cooled calcium carbide blocks are conveyed to a dry quenching furnace to extract hot gas and are introduced into a waste heat boiler for heat recovery. This approach has the following disadvantages:
1. calcium carbide liquid easily flows into the adjacent split calcium carbide dies, and the conveyor belt is easily damaged after solidification;
2. the high-temperature calcium carbide liquid is solidified in a natural cooling mode, so that a longer conveying chain belt and cooling time are needed, the temperature resistance requirement of conveying chain belt materials is high, and meanwhile, the latent heat in the calcium carbide solidification process is not effectively recovered;
3. the actual calcium carbide liquid is in a solid-liquid mixed state, flows out and is not smooth, the normal discharging can be realized only by the furnace stamping procedure, semi-solidified soft calcium carbide blocks are often mixed in the furnace stamping device, and the scraping plate cannot ensure that the calcium carbide liquid is scraped into the die uniformly.

In the present embodiment, referring to fig. 2, the chain belt 12 may be constituted by the bar-shaped mold plates 121 connected to each other; referring to fig. 3, the lower ends of the adjacent strip-shaped mold plates 121 are hinged, and the upper ends can be connected by a telescopic chain 123, so that stable transportation of the chain belt 12 can be ensured; the surface of the strip-shaped mold disc 121 is provided with a plurality of calcium carbide molds 122 along the direction perpendicular to the conveying direction, and the calcium carbide molds are used for receiving molten calcium carbide liquid output by a calcium carbide furnace discharge port.
Referring to fig. 3 to 6, in this embodiment, as a preferred structure of the strip-shaped mold disc 121 for facilitating demolding, a top block receiving hole 1222 is provided at the bottom of the calcium carbide mold 122 for providing a liftable top block 1221, and a protrusion 111 is provided on the outer wall of the driving wheel 11 located at the tail of the upper chain belt 12, and the protrusion 111 is adapted to push the corresponding top block 1221 so as to demold the calcium carbide block in the corresponding calcium carbide mold 122.

of course, in some application scenarios, the calcium carbide blocks between adjacent strip-shaped mold discs 121 may also be partially adhered along the conveying direction, so, referring to fig. 1, the adhered portions may be crushed during the demolding process by providing an auxiliary crushing mechanism 8; alternatively, the additional crushing mechanism 8 may comprise a crushing roller for crushing the upper surface of the strip-shaped mould disc 121.
In this embodiment, optionally, the chain belt type calcium carbide granulation waste heat recovery system further includes: a rolling mechanism 5; the rolling mechanism 5 is arranged above the upper chain belt 12 and is positioned at the upstream of the heat collecting mechanism 2 and used for assisting molten calcium carbide liquid to be pressed into the strip-shaped mould disc 121; optionally, the rolling mechanism 5 is used for assisting the molten calcium carbide to hydraulically enter the strip-shaped mold disc 121; in the discharging process, the calcium carbide liquid is in a solid-liquid mixed state, softer calcium carbide blocks are contained in the calcium carbide liquid, the fluidity of the calcium carbide liquid is higher, the viscosity of the calcium carbide liquid is higher, and the calcium carbide liquid is easy to stack, so that a rolling mechanism is arranged for flattening the stacked calcium carbide liquid, and the calcium carbide liquid uniformly enters the calcium carbide die 122.
