Description
Technical Field
The invention relates to a calcium carbide production device, in particular to a ring-type calcium carbide discharging and crushing integrated machine.
Background
At present, a series of problems exist in the calcium carbide discharging and crushing process route, and the method comprises the following steps:
(1) The tapping efficiency is low. The calcium carbide production process is a dynamic change process, the quantity of calcium carbide discharged from the furnace every time is changed according to different furnace conditions, but the quantity of the loaded calcium carbide pots is limited and is not more than 15 at most due to the limitation of the capacity and the capacity of the winch equipment, the winch is frequently jumped and stopped, the quantity of calcium carbide discharged from the furnace every time is limited in a certain range, and the furnace discharging efficiency is hardly influenced by timely adjustment according to the actual production conditions; in addition, because the winch equipment is too small in selection and is used for a long time, the jump stop fault is easy to occur. Particularly, when the furnace is discharged, the winch is jumped to stop, so that a large amount of calcium carbide overflows onto the discharging track, and the furnace discharging needs to be stopped urgently. The method not only reduces the discharging efficiency of the calcium carbide and increases the calcium carbide loss, but also burns out equipment and rails, increases the cleaning and maintenance workload of discharging workers, and severely restricts and influences the production load and the operation rate of the calcium carbide furnace.
(2) The cooling time is too long, the occupied area is large, and the connection between upstream and downstream production is not smooth. After flowing into the carbide pot, the incandescent carbide is coagulated into a whole piece of carbide lump with the size of about 1880 x 1480 x (480-580) mm, and the weight of each piece of carbide lump is about 1.6 tons. The material is placed in a cold breaking workshop for cooling, the cooling time is more than 72 hours in summer and more than 48 hours in winter. The storage capacity of the calcium carbide cold breaking workshop cannot be matched with the production capacity of the calcium carbide cold breaking workshop, and particularly in summer, the production load rate of the acetylene generating device is affected because the calcium carbide cannot be cooled to a specified temperature (less than 100 ℃) due to the limitation of the storage space and cannot enter the next working procedure.
(3) Complicated procedures, frequent equipment failure and high equipment maintenance cost. At present, the equipment on the discharging and crushing process route of the calcium carbide furnace comprises: the device comprises a calcium carbide pot, a furnace discharging trolley, a furnace discharging track, a winch, a double-beam bridge crane, a woodpecker digger, a pot turning machine, a heavy plate machine, a primary crusher, a tape machine, a secondary crusher and a tertiary crusher. The production environment of the calcium carbide is extremely bad, the factors such as high temperature and dust on site can cause high equipment failure rate, especially when the working condition fluctuates, the sudden events are more, and the normal operation of the whole tapping and crushing system can be influenced when equipment on any link has problems. Moreover, the equipment and accessories thereof are easy to consume and damage, and the equipment maintenance and replacement cost is high.
(4) The calcium carbide has high loss and high energy consumption. After the calcium carbide flows into a calcium carbide pot to be cooled and hoisted to the next working procedure, the calcium carbide is subjected to a long-time cooling process and is dumped for several times. In the process of cooling and transporting, according to actual production experience measurement and calculation, the loss of one ton of calcium carbide furnace is about 0.062 ton, for example, in the process of transporting, the loss of blocky calcium carbide is increased. In the process of transporting and crushing the calcium carbide, most of the calcium carbide is high-power movable equipment and hoisting equipment, and the electricity consumption and the energy consumption are extremely high.
(5) The working intensity is high, and the labor force is high. At present, the equipment on the discharging and crushing process route of the calcium carbide furnace comprises: the process is complex, and personnel are needed in each process, so that the labor consumption is high. In the whole procedures of discharging and crushing the calcium carbide, the labor intensity of operators is extremely high because a large amount of blocky calcium carbide with the weight of about 1.6 tons is required to be dumped.
(6) Has great environmental pollution. The calcium carbide transferring and crushing links are two points with the largest dust emission in the calcium carbide production process, and due to the limitation of process conditions, equipment type selection and space, the floor area is large, the route is long, the dust emission points are more, the calcium carbide dust flies everywhere, the dust collection facility is difficult to collect dust in an omnibearing way, the field operation condition is extremely poor, and the environmental pollution is serious.
(7) There is a great potential safety hazard. The calcium carbide is in the calcium carbide pot and is a relative semi-closed space, a large amount of calcium carbide is concentrated in the calcium carbide pot, and if water leakage occurs in equipment at a furnace outlet, a flash explosion accident occurs; in the transportation process of the calcium carbide, the calcium carbide is required to be transported for 3 to 5 times, the crown block is hoisted, normally discharged, personnel hold/change the pot, a large amount of space is subjected to three-dimensional cross operation, a plurality of visual blind spots exist, and safety accidents such as burn, smash injury, mechanical injury and the like are easy to occur. Therefore, the serious potential safety hazard exists near the outlet of the calcium carbide furnace and in the cold breaking factory building.
