Description
Technical Field
The invention relates to a calcium carbide conveying line and a conveying track thereof.
Background
The main component of the calcium carbide is calcium carbide, which is a very important basic chemical raw material. The traditional method for producing the calcium carbide is as follows: mixing limestone and carbon-containing raw materials (such as coke, anthracite or petroleum coke) in proportion, calcining in a calcium carbide furnace to above 2000 deg.C to form molten liquid state, discharging from the furnace mouth at the bottom of the side of the calcium carbide furnace, and cooling and solidifying. The discharging process in the traditional calcium carbide industry is rough, and the calcium carbide discharging process is divided into two parts: the first part is that an operator controls a winch and a calcium carbide trolley to enable molten calcium carbide to flow into each calcium carbide pot from a calcium carbide furnace, then the calcium carbide pot is conveyed to a cooling workshop for cooling, and finally cooled calcium carbide solids are lifted out of the calcium carbide pot by a crane and a clamp; the second part is hole blocking, burning-through, slag skimming and slag pulling which are carried out by workers on a stokehole working platform in the process of discharging calcium carbide. By adopting a manual operation mode, workers need to perform high-strength operation under severe conditions of high temperature and high dust, and great potential safety hazards exist.
The Chinese patent with the publication number of CN 104986161B discloses a calcium carbide conveying train, and provides a calcium carbide conveying line, which comprises a calcium carbide trolley for containing calcium carbide melt and a conveying track for the calcium carbide trolley to walk. The conveying track comprises a horizontal track and a spiral track, and the horizontal track and the spiral track are connected end to form a closed loop; the spiral track comprises an upper layer supporting track for supporting the calcium carbide trolley, and further comprises a lower layer hanging track for hanging the calcium carbide trolley, wherein the spiral track is spirally wound around a horizontal axis in a left-hand or right-hand mode, then is spirally wound in a right-hand or left-hand mode by the same angle, a discharging section is formed by the left-hand or right-hand spirally wound part, and a resetting section is formed by the right-hand or right-hand spirally wound part. The carbide dolly can pass through the bulb round pin in proper order and articulate and form the closed loop, and each carbide dolly all includes carbide pot, fixed wheel and swing wheel, and the swing axis of swing wheel is on a parallel with the advancing direction of dolly for can realize the upset when the carbide dolly passes through spiral track, and then realize unloading and reset. A belt conveyor is arranged below the spiral track and used as a bearing device for bearing the solidified calcium carbide solids.
However, when the existing calcium carbide conveying line discharges, the calcium carbide trolley enters the spiral track to turn sideways towards the left side and the right side of the advancing direction, at the moment, solidified calcium carbide solids can fall down after the calcium carbide pot is completely turned downwards, uncertainty exists in falling time and falling points, the supporting device below the conveying track needs to be arranged longer along the conveying track, the width needs to be arranged wider to ensure that the calcium carbide solids are effectively supported, and therefore cost of the belt conveyor is directly increased, occupied area is increased, and land cost is increased. In addition, the lateral overturning of the calcium carbide trolley can generate side overturning moment on the conveying track, the structural stability and rigidity of the conveying track need to be improved, and the cost is increased. Furthermore, uncertainty in the timing and drop points of the carbide solids can also lead to safety risks.
