Description

Technical Field

[0001] This application relates to the field of calcium carbide technology, and in particular to a furnace trolley for calcium carbide production with a melt-resistant function. Background Technology

[0002] In the calcium carbide production process, molten calcium carbide, after being smelted in a calcium carbide furnace, flows out of the furnace and into a calcium carbide pot placed on a tapping trolley, which then transports it. Because a small amount of liquid ferrosilicon is produced during calcium carbide smelting, and liquid ferrosilicon has a high heat storage capacity, and the tapping trolleys currently used are almost all made of steel, the heat from the liquid ferrosilicon transferred through the calcium carbide pot to the tapping trolley may cause the trolley to burn out. If the tapping trolley burns out, the contact between the calcium carbide pot and the trolley may become unstable, causing the pot to tip over. This could lead to the outflow of the high-temperature molten calcium carbide, causing overflow and other problems, threatening the safety of the tapping workers. Furthermore, the tapping trolley requires repair after burning out, increasing the frequency and cost of maintenance. Utility Model Content

[0003] This application provides a furnace exit trolley with a melting-resistant function for calcium carbide production, in order to solve the technical problems described in the background art above.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] This application provides a furnace exit trolley with a melting-resistant function for calcium carbide production, comprising:

[0006] The furnace unloading trolley body has multiple first limiting plates evenly spaced on the upper surface of the frame of the furnace unloading trolley body near its periphery.

[0007] The fixed frame body has multiple second limiting plates on its upper surface that correspond one-to-one with the multiple first limiting plates. Each second limiting plate is detachably connected to its corresponding first limiting plate by fasteners.

[0008] A fusible plate is embedded in the fixed frame body and a calcium carbide pot containing calcium carbide is placed on its upper surface. The fusible plate is used to prevent the calcium carbide from transferring its heat to the unloading trolley body through the calcium carbide pot, thereby preventing the unloading trolley body from melting.

[0009] Optionally, the fixing frame body includes a concave plate and a straight plate;

[0010] The straight plate can be detachably connected to the concave plate and enclosed to form the fixed frame body. A first fixing groove is provided on the inner peripheral wall of the concave plate, and a second fixing groove is provided on the side wall of the straight plate near the concave plate. The first fixing groove and the second fixing groove are connected to form a through groove for embedding and fixing the fusible resist plate.

[0011] Optionally, the distance between the inner top surface of the first fixing groove and the upper surface of the concave plate, and the distance between the inner top surface of the second fixing groove and the upper surface of the straight plate, are all preset.

[0012] The preset distance is 1 / 3 to 1 / 2 of the height of the calcium carbide pot.

[0013] Optionally, the concave plate has a first insertion hole of a preset depth at both ends near the straight plate, and the straight plate is provided with a plug that matches the mounting hole, and the plug is inserted into the first insertion hole;

[0014] The preset depth is greater than 1 / 2 of the length or width of the concave plate.

[0015] Optionally, each of the insert rods is provided with a second insertion hole, and the concave plate is provided with a through hole that matches the second insertion hole. The concave plate and the insert rod are locked together by a pin passing through the through hole and extending into the second insertion hole.

[0016] Optionally, a support plate for supporting the flame-retardant plate is provided between the two opposite inner sidewalls of the concave plate, and the lower surface of the support plate is in the same horizontal plane as the lower surface of the concave plate.

[0017] Optionally, the refractory plate is made of corundum wear-resistant plastic or high-alumina refractory brick.

[0018] Optionally, the fasteners include fastening bolts and nuts;

[0019] Each of the first limiting plates and each of the second limiting plates is provided with a first threaded through hole and a second threaded through hole that match the fastening bolt. The fastening bolt passes through the first threaded through hole and the second threaded through hole in sequence. The nut is sleeved on the fastening bolt to achieve a fixed connection between the first limiting plate and the second limiting plate.

[0020] The calcium carbide production furnace trolley with anti-melting function provided in this application achieves fixation of the anti-melting plate by placing it within a fixed frame body. The fixed frame body with the anti-melting plate is then placed on the upper surface of the furnace trolley body, and fasteners are used to secure a second limiting plate on the fixed frame body to a first limiting plate on the furnace trolley. This ensures a stable connection between the fixed frame body with the anti-melting plate and the furnace trolley. The calcium carbide pot containing calcium carbide is then placed on the anti-melting plate, preventing the calcium carbide from transferring its heat through the pot to the furnace trolley body, thus avoiding melting and preventing calcium carbide overflow or flow problems. Therefore, this application not only ensures the safety of furnace workers but also reduces the frequency and cost of furnace trolley maintenance. Furthermore, the connection method between the fixed frame body and the furnace trolley facilitates installation and disassembly of both, improving the ease of installation and disassembly of the anti-melting plate and facilitating inspection and maintenance of the anti-melting plate.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0030] refer to Figures 1 to 6 This application provides a furnace trolley with a melting-resistant function for calcium carbide production, comprising:

[0031] The furnace unloading trolley body 100 has multiple first limiting plates 101 evenly spaced on the upper surface of its frame near its periphery; wherein, each side of the furnace unloading trolley body 100 has at least one first limiting plate 101 on its upper surface, and the specific setting can be made according to the actual situation, but this application does not make a specific limitation on it.

[0032] The fixed frame body 200 has multiple second limiting plates 201 on its upper surface, each corresponding to one of the multiple first limiting plates 101. Each second limiting plate 201 is detachably connected to its corresponding first limiting plate 101 via a fastener 300. The fastener 300 can be a bolt, and its specific configuration can be chosen according to actual needs; however, this application does not further limit its use. Specifically, the fastener 300 passes sequentially through the first limiting plate 101 and the corresponding second limiting plate 201, thereby fixing the first limiting plate 101 and the second limiting plate 201 together.

[0033] A heat-resistant plate 400 is embedded within the fixed frame body 200, and a calcium carbide pot containing calcium carbide is placed on its upper surface. This heat-resistant plate prevents the calcium carbide from transferring its heat to the unloading trolley body 100 via the pot, thus preventing the unloading trolley body 100 from melting. In the actual production process of calcium carbide, the temperature of the liquid calcium carbide produced by the calcium carbide furnace reaches approximately 1500℃. The liquid calcium carbide flows into the calcium carbide pot on the unloading trolley body 100. After the pot is filled with a predetermined volume of liquid calcium carbide, the unloading trolley body 100 moves along a track to a cooling workshop for cooling. Specific processes can be referenced from existing liquid calcium carbide production processes, which will not be elaborated upon here. Because of the high temperature of liquid calcium carbide and the large heat storage capacity of the liquid ferrosilicon within it, the heat stored in the liquid calcium carbide and liquid ferrosilicon is transferred to the anti-thermal plate 400 via the calcium carbide pot during the process of moving the liquid calcium carbide to the cooling workshop. The anti-thermal plate 400 prevents the heat from being transferred to the unloading trolley body 100, thus preventing the unloading trolley body 100 from melting. This extends the service life of the unloading trolley body 100 and reduces the frequency of inspection and maintenance of the unloading trolley body 100.

[0034] The calcium carbide production trolley with anti-melting function provided in this application fixes the anti-melting plate 400 inside the fixed frame body 200. Then, the fixed frame body 200 with the anti-melting plate 400 fixed is placed on the upper surface of the trolley body 100 and the second limiting plate 201 on the fixed frame body 200 is fixed together with the first limiting plate 101 on the trolley body 100 by fasteners 300. This makes the fixed frame body 200 with the anti-melting plate 400 and the trolley body 100 stably connected. Then, the calcium carbide pot containing calcium carbide is placed on the anti-melting plate 400. This prevents the calcium carbide from transferring its heat to the trolley body 100 through the calcium carbide pot, thus preventing the trolley body 100 from melting and avoiding calcium carbide overflow and flow. Therefore, this application not only ensures the personal safety of the furnace workers, but also reduces the maintenance frequency and cost of the furnace trolley body 100. In addition, the connection method between the fixed frame body 200 and the furnace trolley body 100 facilitates the installation and disassembly of both, thereby improving the convenience of installing and disassembling the fusible resist plate 400, and facilitating the inspection and maintenance of the fusible resist plate 400.

[0035] In some embodiments, reference Figure 3 and Figure 4The fixing frame body 200 in this application includes a concave plate 202 and a straight plate 203. Specifically, the straight plate 203 can be detachably connected to the concave plate 202 and enclose the fixing frame body 200. A first fixing groove 2021 is formed on the inner peripheral wall of the concave plate 202, and a second fixing groove 2031 is formed on the side wall of the straight plate 203 near the concave plate 202. The first fixing groove 2021 and the second fixing groove 2031 communicate to form a through groove 500 for embedding and fixing the fusible resist plate 400. A plurality of second limiting plates 201 are sequentially arranged on the corresponding upper surfaces of the side walls of the concave plate 202 and the straight plate 203.

[0036] In the above embodiment, during the process of installing the fusible resist plate 400 inside the fixed frame body 200, one side of the fusible resist plate 400 is installed in the first fixing groove 2021 on the concave plate 202. Then, the second fixing groove 2031 on the straight plate 203 is aligned with the end of the fusible resist plate 400 that is away from the first fixing groove 2021 and located outside the first fixing groove 2021. The straight plate 203 is then pushed towards the fusible resist plate 400, thereby installing the fusible resist plate 400 in the first fixing groove 2021. Within the through groove 500 formed by the first fixed groove 2031 and the second fixed groove 2031, the second limiting plate 201 on the concave plate 202 and the second limiting plate 201 on the straight plate 203 are connected to the first limiting plate 101 on the furnace trolley body 100 by fasteners 300, thereby fixing the fusible resist plate 400 on the furnace trolley body 100. The above-mentioned concave plate 202 and straight plate 203 facilitate the installation and disassembly of the fusible resist plate 400, improving its convenience for inspection and maintenance.

[0037] In some embodiments, reference Figure 1 and Figure 2 In this application, the inner top surface of the first fixing groove 2021 is at a predetermined distance from the upper surface of the concave plate 202, and the inner top surface of the second fixing groove 2031 is at a predetermined distance from the upper surface of the straight plate 203. This predetermined distance ensures that the upper surface of the resist plate 400, fixed within the through groove 500 formed by the first fixing groove 2021 and the second fixing groove 2031, forms a groove with the upper surfaces of the concave plate 202 and the straight plate 203. This groove helps to fix the calcium carbide pot placed on the resist plate 400, improving the stability of the calcium carbide pot on the resist plate 400. The predetermined distance can be set according to actual needs, and this application does not specifically limit it.

[0038] In addition, the preset distance is 1 / 3 to 1 / 2 of the height of the calcium carbide pot, which can ensure the stability of the calcium carbide pot containing liquid calcium carbide on the resist plate 400.

[0039] In some embodiments, reference Figure 3 and Figure 4In this application, the concave plate 202 has first insertion holes 2022 of a preset depth at both ends near the straight plate 203. The straight plate 203 is provided with insertion rods 2032 that match the first insertion holes 2022. The insertion rods 2032 are inserted into the first insertion holes 2022. The connection between the straight plate 203 and the concave plate 202 is realized by inserting the insertion rods 2032 on the straight plate 203 into the first insertion holes 2022 on the concave plate 202, thereby realizing the joint fixation of the fusible resist plate 400 by the concave plate 202 and the straight plate 203.

[0040] In addition, the preset depth is greater than half the length or width of the concave plate 202. This ensures a tighter connection between the straight plate 203 and the concave plate 202, thereby improving the stability of their connection. The specific value of the preset depth can be set according to actual needs, and this application does not impose a specific limitation on it.

[0041] In some embodiments, reference Figure 3 and Figure 4 In this application, each insertion rod 2032 is provided with a second insertion hole 600, and the concave plate 202 is provided with a through hole 2023 that matches the second insertion hole 600. The concave plate 202 and the insertion rod 2032 are locked together by a pin 700 passing through the through hole 2023 and extending into the second insertion hole 600.

[0042] In the above embodiment, by passing the bottom end of the pin 700 through the through hole 2023 on the concave plate 202 and the second insertion hole 600 on the insertion rod 2032 in sequence, the concave plate 202 and the insertion rod 2032 are fixed. This makes the connection between the concave plate 202 and the straight plate 203 more stable, thereby ensuring the stability of the fixation of the fusible resist plate 400 sandwiched in the through groove 500 by the concave plate 202 and the straight plate 203.

[0043] In some embodiments, reference Figure 3 , Figure 4 and Figure 5 In this application, a support plate 2024 for supporting the fusible resist plate 400 is provided between the two opposing inner sidewalls of the concave plate 202. The lower surface of the support plate 2024 is in the same horizontal plane as the lower surface of the concave plate 202. To ensure the stability of the support plate 2024 in supporting the lower surface of the fusible resist plate 400, the thickness of the support plate 2024 is the same as the thickness of the distance between the inner bottom surface of the first fixing groove 2021 and the lower surface of the concave plate 202.

[0044] In the above embodiments, the width of the support plate 2024 can be set according to actual needs. The purpose of setting the support plate 2024 is to effectively support the lower surface of the resist plate 400, so that the stability of the resist plate 400 in the through groove 500 is higher, and thus the resist plate 400 can better support the calcium carbide pot containing liquid calcium carbide.

[0045] In some embodiments, the refractory plate 400 in this application is made of corundum wear-resistant plastic or high-alumina refractory brick. The specific design can be determined according to actual needs, and this application does not impose any specific limitations on it.

[0046] In the above embodiments, corundum wear-resistant plastic is a high-performance monolithic refractory material, mainly composed of corundum (alumina), supplemented with other refractory aggregates, binders, and additives. It possesses excellent wear resistance, high-temperature resistance, and good workability. High-alumina refractory brick is a neutral refractory material with alumina (Al2O3) as its main component, typically containing over 48%, and up to 99%. This type of refractory brick exhibits excellent high-temperature resistance, thermal shock resistance, slag resistance, and chemical stability. Therefore, the refractory plate made of corundum wear-resistant plastic or high-alumina refractory brick in this application can withstand temperatures of approximately 1500℃, effectively preventing the heat stored in liquid calcium carbide and liquid ferrosilicon from being transferred through the calcium carbide pot to the unloading car body 100, thus extending the service life of the unloading car body 100.

[0047] In some embodiments, reference Figure 1 and Figure 2 The fastener 300 in this application includes a fastening bolt 301 and a nut 302. Specifically, each first limiting plate 101 and each second limiting plate 201 are respectively provided with a first threaded through hole 1011 and a second threaded through hole 2011 that match the fastening bolt 301. The fastening bolt 301 passes through the first threaded through hole 1011 and the second threaded through hole 2011 in sequence, and the nut 302 is sleeved on the fastening bolt 301 to realize the fixed connection between the first limiting plate 101 and the second limiting plate 201.

[0048] The above connection method facilitates the fixing of the first limiting plate 101 and the second limiting plate 201 together, and the connection between the fixed frame body 200 and the unloading trolley body 100 after fixing is relatively stable. In addition, the first limiting plate 101 and the second limiting plate 201 are also easy to disassemble, making the fixing and disassembly of the fixed frame body 200 and the unloading trolley body 100 more convenient.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
