Description

Technical Field

[0001] The invention relates to the field of calcium carbide furnaces, and in particular to a calcium carbide furnace unloading trolley. Background Art

[0002] Since the calcium carbide furnace unloading trolley was put into operation, it has been affected by the severe unloading conditions in the initial stage of furnace opening. After a long period of production operation, the failure rate of the calcium carbide furnace unloading trolley in the production operation process has become increasingly high. Whether the calcium carbide furnace unloading trolley can operate normally has a direct impact on the production of the calcium carbide furnace. While other systems of the entire calcium carbide production line have been transformed and improved one after another, the improvement of the calcium carbide furnace unloading trolley system is imminent.

[0003] However, the existing calcium carbide furnace unloading trolley has the following problems during operation: when the unloading trolley is loaded with high-temperature liquid calcium carbide for transportation, the unloading trolley is in an open state during operation, and the high-temperature liquid calcium carbide will inevitably splash during transportation, causing damage to equipment and operators. If the unloading trolley rolls over, the high-temperature liquid calcium carbide will cause losses due to the rollover; the calcium carbide trolley carrying high-temperature liquid calcium carbide can cool the high-temperature liquid calcium carbide during transportation. When the calcium carbide trolley reaches the set position, the calcium carbide trolley unloads the cooled calcium carbide. During this cooling process, the cooling process of the high-temperature liquid calcium carbide belongs to natural cooling, and the cooling efficiency is not high. During this period, the unloading trolley will be stopped to wait for the cooling to be completed, which reduces the work efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a calcium carbide furnace unloading trolley to solve the problem that the unloading trolley is in an open state during operation, high-temperature liquid calcium carbide splashes out and the high-temperature liquid calcium carbide cooling process belongs to natural cooling, and the cooling efficiency is low.
