Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbide furnaces and relates to a device for clearing and cleaning a flue of a calcium carbide furnace. Background Art

[0002] At present, in the normal production process of calcium carbide furnace, the main raw materials are coke and lime. When the raw materials react in the furnace, a large amount of gas will be generated. The gas contains tar and other large amounts of dust particles, which are easy to condense into a hard shell on the pipe wall. In addition, the pipe will bend due to the layout of the entire calcium carbide furnace system. Long-term condensation will cause the inner diameter of the pipe to become smaller, the fan frequency to increase, and the temperature in the purification and filtration bin to be too high. In severe cases, the flue will be blocked and normal production cannot be achieved. The calcium carbide furnace is usually powered off to clean the inspection manholes on each floor. Shovel and crowbar are used, and 5-6 people take turns to work. The cleaning time is long and there are many people. Not only is the labor intensity high, but the quality is difficult to control due to improper cleaning, which causes a lot of inconvenience to the subsequent safe production. Summary of the invention

[0017] Embodiment 1: As attached Figure 1 , 2As shown, the device for clearing and cleaning the flue of calcium carbide furnace comprises a driving device, a connector 1, a flexible shaft 2, an outer spring 3 and a cleaning disc. The output end of the driving device is connected to the right end of the connector 1 by transmission. The left side of the connector 1 is provided with three mounting holes with openings to the left. A flexible shaft 2 located in the outer spring 3 is fixedly installed in each mounting hole. A cleaning disc is detachably fixedly installed at the left end of the flexible shaft 2. The cleaning disc comprises a connecting disc 4 and cleaning teeth 5. A connecting hole 6 is provided on the connecting disc 4 corresponding to the position of each flexible shaft 2. A plurality of cleaning teeth 5 are provided at intervals along the circumference of the outer side of the connecting disc 4. During use, the cleaning disc is rotated by setting a driving device to complete the flue cleaning operation. The three flexible shafts 2 are synchronously rotated by setting a connector 1. The three flexible shafts 2 are sleeved together by setting an outer spring 3 to avoid scattering during rotation. The cleaning disc is rotated at high speed on the inner wall of the flue to quickly drop the condensed ash into the furnace.

[0018] According to actual needs, the above-mentioned calcium carbide furnace flue dredging and cleaning device can be further optimized and / or improved:

[0019] Embodiment 2: As attached Figure 1 , 2 As shown, six cleaning teeth 5 are evenly spaced along the circumference of the outer side of the connecting disk 4, and each cleaning tooth 5 is triangular. In the process of use, such an arrangement has a better cleaning effect.

[0020] Embodiment 3: As attached Figure 1 , 2 As shown, it also includes a fixing bolt 12 and a clamping bolt 13. The fixing bolt 12 is fixedly installed on the outer side of the left part of each flexible shaft 2 through a threaded connection. The left side of the fixing bolt 12 abuts against the corresponding position on the right side of the connecting plate 4. The clamping bolt 13 is fixedly installed on the outer side of the left part of the flexible shaft 2 corresponding to the left side of the connecting plate 4 through a threaded connection. The right side of the clamping bolt 13 abuts against the corresponding position on the left side of the connecting plate 4. During use, through such a setting, it is convenient to clean the faceplate and install the three flexible shafts 2 together.

[0021] Embodiment 4: As attached Figure 1 , 2As shown, the driving device includes a permanent magnetic coupling 7, a torque sensor 8, a reducer 9, a motor 10 and a frequency converter 11.
