Description

Technical Field

[0001] This utility model belongs to the field of calcium carbide furnace technology, and in particular relates to a calcium carbide furnace with a cleaning structure. Background Technology

[0002] A calcium carbide furnace is a submerged arc furnace mainly used to produce calcium carbide, or calcium carbide. The main raw materials, quicklime (CaO) and carbonaceous raw materials (such as coke, anthracite, and petroleum coke), react in the electric furnace at high temperatures of 1800-2200℃ using electric arc heat or resistance heat.

[0003] Some calcium carbide furnaces are equipped with access ports for maintenance and cleaning. Workers need to enter and exit the access ports to clean or repair the interior. However, the existing access port doors require many screws to be fixed, and many screws need to be operated when removing them. After cleaning, many screws also need to be installed, which makes it quite troublesome to open or close the access port for cleaning and maintenance of conventional calcium carbide furnaces.

[0004] Therefore, we propose a calcium carbide furnace with a cleaning structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that it is troublesome to open or close the cleaning and maintenance entrance of conventional calcium carbide furnaces, and to propose a calcium carbide furnace with a cleaning structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A calcium carbide furnace with a cleaning structure includes a nut, a furnace body, a door frame, and a cleaning door. The nut is threaded onto the side of the cleaning door and makes movable contact with the door frame. The cleaning door is movably inserted into the door frame, which is fixedly connected to the furnace body. The internal space of the door frame communicates with the internal space of the furnace body. By unscrewing the nut and pulling the cleaning door out along the door frame, an opening is created, thus opening the entrance to the furnace body. The furnace body can then be cleaned by entering through the door frame. By manipulating only a few nuts, the difficulty of opening or closing the cleaning door is reduced, thereby simplifying the cleaning process.

[0008] Preferably, the calcium carbide furnace body includes a furnace shell, the upper part of which is perforated to provide a cleaning inlet and outlet. A door frame covers the cleaning inlet and outlet, and the base of the door frame is fixedly connected to the furnace shell. Access to the furnace shell is made through the cleaning inlet and outlet to clean the interior. After cleaning, access to the calcium carbide furnace body is facilitated through the cleaning inlet and outlet.

[0009] Preferably, the door frame includes a frame body with a trapezoidal groove inside. One side of the frame body has a perforated insertion hole. The cleaning door is slidably inserted into the trapezoidal groove, with its side passing through the insertion hole. The base of the frame body is fixedly connected to the upper part of the furnace shell. After unscrewing the nut, the cleaning door is pulled out from the trapezoidal groove, opening the door frame. The cleaning door is then reinserted into the trapezoidal groove, and the nut is tightened again, causing the cleaning door to re-block the cleaning inlet and outlet, facilitating opening or blocking of the cleaning inlet and outlet.

[0010] Preferably, the cleaning door includes a door panel, one end of which is fixedly connected to a bolt. The door panel is movably inserted into a trapezoidal groove, and the bolt slides through the insertion hole. A nut is threaded onto the bolt. By unscrewing the nut, the door panel is pulled out of the trapezoidal groove, opening the door frame. The door panel is then pulled back into the trapezoidal groove, allowing the bolt to insert into the insertion hole. Finally, the nut is tightened to close the cleaning door again, facilitating the opening and closing of the door frame.

[0011] Preferably, the cleaning door includes a guide head, one end of which is fixedly connected to one end of a bolt. When the cleaning door is connected to the door frame, the guide head facilitates the bolt's entry into the insertion hole.

[0012] Preferably, the cleaning door further includes a lifting ring, one end of which is fixedly connected to the door panel. The lifting ring facilitates control of the cleaning door using lifting equipment.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Unscrew the nuts, then pull the cleaning door out along the door frame to open the door frame opening, thereby opening the entrance to the calcium carbide furnace body. Enter the calcium carbide furnace body through the door frame to clean the calcium carbide furnace body. By operating a few nuts, the difficulty of opening or closing the cleaning door is reduced, thereby reducing the difficulty of cleaning the calcium carbide furnace body.

[0015] 2. Enter the furnace shell through the cleaning inlet and outlet to clean the inside of the furnace shell. After cleaning, exit the calcium carbide furnace body through the cleaning inlet and outlet to facilitate entry and exit from the calcium carbide furnace body.

[0016] 3. After unscrewing the nut, pull the cleaning door out of the trapezoidal slide, open the opening of the door frame, reinsert the cleaning door into the trapezoidal slide, and tighten the nut again to make the cleaning door block the cleaning inlet and outlet again, making it easy to open or block the cleaning inlet and outlet.

[0017] 4. Unscrew the nut, pull the door panel out of the trapezoidal slide, open the door frame opening, pull the door panel back into the trapezoidal slide, insert the bolt into the socket, and then tighten the nut to close the cleaning door again, making it easy to open or close the door frame.
