Description

Technical field:

[0001] The utility model relates to the field of calcium carbide production, in particular to a track turnout structure for a calcium carbide furnace. Background technology:

[0002] Calcium carbide furnace is the main equipment for producing calcium carbide. In the calcium carbide furnace, the high temperature generated by the electric arc causes the charge to melt and react to produce calcium carbide. Since the reaction temperature is as high as over 2000℃, such a high temperature is difficult for general refractory materials to withstand. Therefore, the volume of the furnace body must be larger than the reaction space. In other words, a layer of charge should be left between the reaction zone and the furnace lining to protect the furnace lining.

[0003] There are many shapes of furnace bodies, including round, oval, square and rectangular. From the point of view of thermodynamics, round furnaces are more advantageous. In fact, the choice of furnace shape is mainly determined by the arrangement of electrode positions and the installation position of carbon monoxide extraction equipment. It can be said that most of today's calcium carbide furnaces are round furnaces. Only a few use other shapes.

[0004] The size of the reaction space in the furnace is determined by the size and distance of the electrodes and the range of the arc. The distance of the circular electrode is proportional to its diameter. The electrode diameter varies with the capacity of the furnace. The electrode diameter is determined by the current density allowed. The current of the electrode is determined by the capacity of the transformer. The final conclusion is that the size of the furnace is determined by the capacity of its transformer.

[0005] When the molten calcium carbide generated by reduction in the calcium carbide furnace accumulates to a certain extent, the furnace eye is opened with a burner to release the calcium carbide, and the liquid calcium carbide flows into the calcium carbide pot through the furnace outlet. The calcium carbide pot car is pulled to the cooling workshop by a traction trolley. After natural cooling until the calcium carbide solidifies into a lump, the hook bridge crane equipped with an automatic clamp lifts the calcium carbide out of the pot and places it in the cooling area for further cooling. The cooled calcium carbide is loaded and shipped out by truck.

[0006] The traction trolley is pulled to the cooling workshop through the furnace discharge system track. The calcium carbide furnace has three furnace discharge ports, corresponding to three furnace discharge tracks. However, the furnace discharge trolleys on the three tracks cannot be used as backup for each other. When equipment failure occurs, the faulty line will stop being used, which will cause one of the furnace discharge ports to be unable to output, affecting production efficiency. Utility model content:

[0007] The utility model aims to provide a track turnout structure for a calcium carbide furnace.

[0008] The utility model is implemented by the following technical solutions:

[0009] A calcium carbide furnace exit track turnout structure comprises a plurality of initial track groups, a plurality of sleepers are laid at the bottom end of each initial track group, auxiliary turnouts are laid between each adjacent initial track group, and each auxiliary turnout is fixed to the corresponding sleepers through a plurality of fixing parts.

[0010] Preferably, a stabilizing kit is fitted at the bottom end of the fixing part, and the fixing part is fixed on the side wall of the auxiliary turnout by welding. A locking bolt is inserted into the fixing part, and the bottom end of the locking bolt is threadedly connected to the sleeper. A plurality of positioning blocks are fixed at the top end of the sleeper by casting, and a plurality of positioning holes are provided at the bottom end of each auxiliary turnout, and the top end of the positioning block extends into the corresponding positioning hole and is slidably connected thereto.

[0011] The advantages of the utility model are: two auxiliary branch tracks are added, so that the three initial tracks and the two auxiliary branch tracks form a combination, and the furnace-outlet trolleys on the three initial tracks can change lanes with each other. In this way, even if equipment failure occurs, the furnace-outlet trolley can still be guaranteed to run normally on the other two initial tracks. In addition, two groups of furnace-outlet trolleys can be added. By adding the furnace-outlet trolleys, the cooling time of calcium carbide on the furnace-outlet trolley can be extended, so that the calcium carbide weight can be directly hoisted on the trolley, reducing the steps of putting the calcium carbide pot rack under the calcium carbide pot, reducing labor intensity, and improving work efficiency. Description of the drawings:

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 It is a schematic diagram of the installation of the auxiliary turnout in the utility model;

[0014] Figure 3 It is a schematic diagram of the travel route of the auxiliary turnout and the initial track of the utility model.

[0015] In the figure: initial track 1, auxiliary turnout 2, sleeper 3, fixing part 4, stabilizing kit 5, locking bolt 6, positioning hole 7, positioning block 8. Specific implementation method:

[0016] like Figures 1 to 3As shown, a track turnout structure for a calcium carbide furnace outlet comprises a plurality of groups of initial tracks 1, a plurality of sleepers 3 are laid at the bottom end of each group of initial tracks 1, an auxiliary turnout 2 is laid between each adjacent group of initial tracks 1, each auxiliary turnout 2 is fixed to the corresponding plurality of sleepers 3 by a plurality of fixing members 4, and two auxiliary turnouts 2 are added to the outlet of each calcium carbide furnace, so that the three initial tracks 1 and the two auxiliary turnouts 2 form a combination, so that the outlet trolleys on the three initial tracks 1 can change lanes with each other, and two more groups of outlet trolleys can be added. By adding the outlet trolleys, the cooling time of calcium carbide on the outlet trolley can be extended, so that it can be directly lifted on the trolley. The calcium carbide weight reduces the steps of putting the calcium carbide pot rack under the calcium carbide pot, reduces labor intensity and improves work efficiency. For example, when an initial track 1 has an equipment failure, it can be moved to an adjacent initial track 1 through an auxiliary branch track, which will not affect the normal discharging work. At the same time, the newly added out-of-the-furnace trolley can be placed on the initial track 1 for standby. After an out-of-the-furnace trolley places the freshly-out-of-the-furnace calcium carbide, it can be moved directly to the cooling workshop, but it does not need to be placed on the rack, it can be placed directly on the trolley. Other out-of-the-furnace trolleys can still continue to work, and this initial track can still run other out-of-the-furnace trolleys. This is the role of the newly added auxiliary branch track 2.

[0017] A stabilizing kit 5 is fitted at the bottom end of the fixing part 4, and the fixing part 4 is fixedly installed on the side wall of the auxiliary turnout 2 by welding. A locking bolt 6 is inserted into the fixing part 4, and the bottom end of the locking bolt 6 is threadedly connected to the sleeper 3. A plurality of positioning blocks 8 are fixedly provided at the top of the sleeper 3 by casting. A plurality of positioning holes 7 are provided at the bottom end of each auxiliary turnout 2, and the top end of the positioning block 8 extends into the corresponding positioning hole 7 and is slidably connected thereto. In addition, since the auxiliary turnout 2 is arranged relatively scattered (in order to ensure that there are auxiliary turnouts 2 for the two adjacent initial tracks 1), it is necessary to ensure the long-term use and stability of the auxiliary turnout 2. Therefore, the positioning holes 7 and the positioning blocks 8 are added. On the one hand, it is convenient for positioning and installation, and on the other hand, by cooperating with the stabilizing kit 5, the auxiliary turnout 2 and the sleeper 3 are installed more tightly, thereby avoiding problems such as shaking and ensuring the normal driving of the furnace trolley.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
