Problems solved by technology

[0006] However, after careful analysis, the above scheme still has shortcomings. The molten calcium carbide enters the cooling tower through the sieve plate and forms a solid state in the cooling tower. Although the calcium carbide will be divided into several small pieces after passing through the sieve plate, the cooling process is extremely difficult to control. It will cause small pieces of calcium carbide to coagulate with each other to form large pieces, which is not conducive to heat dissipation. In addition, the structure of the above-mentioned cooling tower is complicated and the formation of calcium carbide cannot be controlled

Embodiment 1

[0025] Such as figure 1 with figure 2 As shown, a calcium carbide cooling preforming mechanism includes a frame 1, and the frame 1 is provided with a preforming mechanism 2 that can be lifted along the vertical direction. When the preforming mechanism 2 has a molten When the calcium carbide hopper 3 is used, the preforming mechanism 2 can be inserted into the calcium carbide in the hopper 3 when it descends, and can be pulled out from the calcium carbide in the hopper 3 when the preforming mechanism 2 rises, so that the calcium carbide in the hopper 3 can form The shape of the preforming mechanism 2.

[0026] In this embodiment, the preforming mechanism 2 can be in various shapes. When the calcium carbide is in a molten state, it is inserted into the calcium carbide and placed for several minutes. The specific placement time is determined according to the process. After the calcium carbide is slightly cooled, it will transform from a molten state to a solid state. At this t...

Embodiment 2

[0031] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as figure 1 with figure 2 As shown, the preforming assembly 5 includes at least one preforming column 6, the length of the preforming column 6 matches the depth of the hopper 3, and the cross-sectional area of ​​the preforming column 6 gradually increases from the bottom to the top. The cross-section of the preformed column 6 can be polygonal, circular or elliptical, etc. As a preferred solution, the outer wall of the preformed column 6 should have a smooth arc, which is easy to pull out from the calcium carbide.

[0032] The working principle of this embodiment is: the shape of the preformed column 6 is easy to insert into calcium carbide, which is convenient for insertion and extraction, and improves the stability of work. 3 causing damage.

Embodiment 3

[0034] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as figure 1 with figure 2 As shown, the preforming assembly 5 includes several preforming columns 6 , the axis lines of the several preforming columns 6 are not on the same plane, and the length of the preforming columns 6 matches the depth of the hopper 3 . The cross-sectional area of ​​the preformed column 6 gradually increases from the bottom to the top.

[0035] The preforming mechanism 2 is fixedly connected with a calcium carbide separating mechanism 7 that can separate the calcium carbide in the hopper 3 when the preforming mechanism 2 is inserted into the hopper 3. When the preforming mechanism 2 is pulled out from the hopper 3, the hopper 3 The calcium carbide in the form forms a shape corresponding to the calcium carbide separation mechanism 7, that is, the shape of the calcium carbide separation mechanism 7 is also retained in the c...

Abstract

The invention belongs to the technical field of calcium carbide production, and relates to a calcium carbide cooling preforming mechanism. The calcium carbide cooling preforming mechanism comprises a rack, a preforming mechanism which can ascend and descend in the vertical direction is arranged on the rack, when a hopper containing molten calcium carbide is arranged below the preforming mechanism, the preforming mechanism can be inserted into the calcium carbide in the hopper when the preforming mechanism descends, and the preforming mechanism can be pulled out from the calcium carbide in the hopper to make the shape of the preforming mechanism formed in the calcium carbide in the hopper when the preforming mechanism ascends. The calcium carbide cooling preforming mechanism is simple in structure, forming control is convenient, continuous production is convenient, a calcium carbide separation mechanism can separate the calcium carbide into regular blocks, heat dissipation is convenient, the subsequent smashing step can be omitted, and therefore the production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of calcium carbide production, and relates to a calcium carbide cooling preforming mechanism. Background technique [0002] Calcium carbide, the main component of calcium carbide, is an inorganic compound, white crystal, the industrial product is gray-black lump, and the cross-section is purple or gray. It reacts violently with water immediately, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc. [0003] The electric furnace smelting method and oxygen heating method are generally used in the industry. The electric furnace smelting method is to melt coke and calcium oxide (molecular formula CaO) in an electric furnace at about 2200 ° C to generate calcium carbide (molecular formula CaC2). Oxygen-thermal method is smelting CaC2 (calcium carbide) by blast furnac...
