Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbide furnaces, in particular to a calcium carbide furnace. Background Art

[0002] Calcium carbide reacts violently with water, producing acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, primarily used to generate acetylene gas. It is also used in organic synthesis and oxyacetylene welding. The industry generally uses electric furnace smelting and oxythermal processes to produce calcium carbide. The electric furnace smelting process involves smelting coke and calcium oxide in an electric furnace at approximately 2200°C to produce calcium carbide. The oxythermal process involves using a blast furnace with oxygen-enriched oxygen to smelt calcium carbide (Calcium Carbide), extracting carbon from limestone, and using a high-temperature, low-pressure gasifier. This "one furnace, three processes" technology allows for the production of calcium carbide by utilizing waste heat and coal ash from the coal gasification process. The coal ash is then melted with ingredients to produce calcium carbide and ferrosilicon (for purification). The "high-temperature, low-pressure" gasifier allows for natural gas production.

[0003] For example, a calcium carbide furnace unloading device disclosed in authorization announcement number CN215638810U uses a support plate that simultaneously moves out of the heating chamber when the sealing plate is opened, allowing for rapid heat dissipation of the support plate and the calcium carbide on it. At the same time, a worker is required to reach into the heating chamber to remove the support plate, which is more convenient and ensures the worker's personal safety.

[0004] However, the above method mainly relies on a pulling mechanism to pull out the support plate. After the box door is closed, the pulling mechanism will remain inside the calcium carbide furnace, which occupies more space inside the calcium carbide furnace. At the same time, only part of the support plate can be pulled out by the pulling mechanism. For this reason, we propose a calcium carbide furnace. Utility Model Content

[0005] The purpose of the utility model is to provide a calcium carbide furnace. By setting a pulling mechanism, the pulling mechanism can be conveniently driven by the box door, so that the support plate can be pulled out by the sliding component. At the same time, the limiting component can prevent the support plate from being disconnected from the calcium carbide furnace box body. At the same time, after the box door is closed at the later stage, the driving component can be used to drive the clamping component to move, so that the calcium carbide furnace box body and the box door are connected.

[0014] Technical effects and advantages of this utility model:

[0015] The driving component drives the clamping component to move, so that the calcium carbide furnace box and the box door are no longer connected, and then the box door is moved outward, so that the box door drives the sliding component to slide, thereby driving the support plate to be pulled out through the box door to dissipate heat. At the same time, the limiting component can limit the sliding component, which can effectively prevent the support plate from being disconnected from the calcium carbide furnace box. Later, the box door is moved back, and then the driving component drives the clamping component to move again to connect the calcium carbide furnace box and the box door. This design can effectively save space inside the calcium carbide furnace box. At the same time, the support plate can change the pulling-out range according to the movement range of the box door, so as to facilitate good heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS
