Description

Leakage-proof device of Roots blower Technical Field The utility model relates to the technical field of Roots fans, in particular to a leakage-proof device of a Roots fan. Background The principle is that two blade rotors are used to make relative motion in the cylinder to compress and convey gas, the fuel gas for converting methanol is coke oven gas, before entering the combustion furnace, the gas blower (Roots blower) is used to make pressurization treatment to raise the coke oven gas from 2KPa to 20KPa, the Roots blower is a shaft transmission device, the fan pressurization cavity, transmission shaft and external environment are provided with skeleton seal to effectively isolate, but due to the design characteristic of the skeleton seal, the complete sealing effect cannot be achieved during operation, and the coke oven gas is leaked. Therefore, there is a need for a leakage prevention device for a Roots blower to solve the above problems. Disclosure of utility model In order to overcome the defects in the prior art, the embodiment of the utility model provides a leakage-proof device of a Roots blower, which can solve the problem that coke oven gas leaks due to the fact that a complete sealing effect cannot be achieved during the running of the Roots blower by arranging a first framework sealing element, a second framework sealing element and a lithium-based grease filling layer, so that the practical use effect of the device is good, and the problems in the background art are solved. In order to achieve the purpose, the technical scheme is that the leakage-proof device of the Roots blower comprises a first framework sealing piece, wherein a second framework sealing piece is arranged on one side of the first framework sealing piece, the outer sides of the first framework sealing piece and the second framework sealing piece are provided with the same sealing jacket, the top of the sealing jacket is provided with an oil filling nozzle, and a lithium-based grease filling layer is arranged inside the sealing jacket. The utility model has the technical effects and advantages that: According to the utility model, the first framework sealing piece, the second framework sealing piece and the lithium-based grease filling layer are arranged, so that the problem that coke oven gas leaks due to the fact that a complete sealing effect cannot be achieved during the running of the Roots blower can be solved, and the practical use effect of the coke oven gas sealing device is good. Drawings Fig. 1 is a schematic diagram of the overall structure of the present utility model. The reference sign is 1, a first framework sealing piece, 2, a second framework sealing piece, 3, a sealing jacket, 4, an oil filling nozzle and 5, a lithium-based grease filling layer. Detailed Description The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model. As shown in fig. 1, the utility model provides a leakage-proof device of a Roots blower, which comprises a first framework sealing piece 1, wherein a second framework sealing piece 2 is arranged on one side of the first framework sealing piece 1, the outer sides of the first framework sealing piece 1 and the second framework sealing piece 2 are provided with the same sealing jacket 3, the top of the sealing jacket 3 is provided with an oil filling nozzle 4, and a lithium-based grease filling layer 5 is arranged inside the sealing jacket 3. The embodiment of the utility model is specifically formed by two groups of framework seals, namely a first framework seal 1 and a second framework seal 2, gaps are reserved between the two groups of seals, lithium grease (butter) is injected into the gaps, and the leakage-free effect is basically achieved through the double functions of the framework seals and the lithium grease, so that the problem that the coke oven gas is leaked due to the fact that the complete sealing effect cannot be achieved during the running period of the Roots blower can be solved, and the practical use effect of the utility model is better.
