[0026] The utility model will be described below in detail with reference to the drawings.

[0027] As Figures 1-6 shown, a steam engine lubricating oil circulating flushing device, including oil tank 1, oil tank 1 one side bottom is equipped with oil pump 101, and the output end of oil pump 101 is connected with oil outlet pipe 102, and the inside of oil tank 1 is equipped with detachable filter plate 103, and the inside wall of oil tank 1 both sides is equipped with inclined insertion slot 104, and filter plate 103 is inclined and inserted in insertion slot 104, and the upward end of filter plate 103 passes out oil tank 1 and is equipped with baffle 105, and the outer wall of baffle 105 is equipped with handle 106. Specifically, the setting of insertion slot 104 and handle 106 is convenient for the cleaning of filter plate 103, and because filter plate 103 is inclined, the impurities in lubricating oil are not easy to accumulate and block in the local position on filter plate 103, and lubricating oil can flow along the surface of filter plate 103 to the inclined lower side, so as to improve the utilization rate of filter plate 103, reduce the blocking condition and reduce the cleaning frequency of filter plate 103. When filter plate 103 is cleaned, filter plate 103 can be directly taken out by holding handle 106, and the operation is simple and convenient to use.

[0028] The oil tank 1 is provided with a filter box 2 on one side of the top, and the filter box 2 is provided with an opening on the front side. A rotating shaft 201 is rotatably connected between the inner walls on the two sides of the filter box 2. A plurality of groups of guide rods 202 are uniformly distributed on the outer wall of the rotating shaft 201.

A first fixing assembly is arranged between the sleeve 204 and the guide rod 202. A screw disc 205 is arranged at one end of the rotating shaft 201 after penetrating out of the filter box 2. A second fixing assembly is arranged between the screw disc 205 and the filter box 2. A protective cover is detachably arranged at the opening of the filter box 2. The protective cover not only protects the guide rod 202 and the sleeve 204, but also prevents the lubricating oil from spilling during the falling process. Specifically, the metal impurities in the lubricating oil can be separated and adsorbed on the outer surface of the sleeve 204 by the magnetic action of the magnetic rod 203. Then the lubricating oil is filtered again by the filter plate 103, so as to realize the purpose of filtering the lubricating oil. The filtering effect is good.

The guide rod 202 is provided with a first threaded hole corresponding to the first bolt 209. The sleeve 204 is locked by rotating the first bolt 209 into the first threaded hole. Specifically, the shaft shoulder 206 can block the lubricating oil on the sleeve 204, so as to avoid the lubricating oil flowing along the surface of the sleeve 204 to the outside during the filtering process of the lubricating oil. The adapter plate 207 can connect a plurality of sleeves 204 together to realize the purpose of synchronous disassembly and improve the cleaning efficiency of the sleeves 204. The adapter plate 207 and the fixing plate 208 can simultaneously fix a plurality of sleeves 204 on the magnetic rod 203, which is convenient for disassembly.

Specifically, when the angle of the rotating shaft 201 needs to be adjusted, the second bolt 211 is unscrewed from the fixing block 210, the fixing of the twist disc 205 is cancelled, then the twist disc 205 is rotated by 90 degrees to drive the rotating shaft 201 to rotate, and finally the fixing block 210 and the filter box 2 are locked by using the second bolt 211.

[0032] A trapezoidal box 3 is arranged above the filter box 2, a plurality of shunt pipes 301 connected with the filter box 2 are arranged at the bottom of the trapezoidal box 3 in a spaced-apart manner, and the lubricating oil can be shunted through the arrangement of the trapezoidal box 3 and the shunt pipes 301, and the shunted lubricating oil can be sprayed on the plurality of sleeve pipes 204 and can be fully contacted with the sleeve pipes 204.

[0033] The trapezoidal box 3 is connected with an oil return pipe 4, and the outer surface of the oil return pipe 4 is sleeved with an electromagnetic heating pipe 401, the arrangement of the electromagnetic heating pipe 401 can heat the lubricating oil entering the trapezoidal box 3 (it is worth noting that the heating temperature is between 50 DEG C and 65 DEG C), the heating of the lubricating oil can reduce the viscosity and increase the flowability, so that the lubricating oil can be better contacted with the sleeve pipe 204, and a better filtering effect can be provided.

[0034] During the working of the utility model, the oil outlet pipe 102 and the oil return pipe 4 are connected with the inlet and outlet ends of the circulating pipeline of the steam engine respectively, the lubricating oil is pumped out from the oil tank 1 by the oil pump 101, and after being used in circulation, the lubricating oil is returned to the trapezoidal box 3 from the oil return pipe 4, the lubricating oil is shunted in the trapezoidal box 3 and flows into the filter box 2 from the plurality of shunt pipes 301, the shunted lubricating oil is sprayed on the plurality of sleeve pipes 204 and can be fully contacted with the sleeve pipes 204, the metal impurities in the lubricating oil can be separated out and adsorbed on the outer surface of the sleeve pipe 204 by the magnetic action of the magnetic bar 203, and then the lubricating oil is filtered again by the filter plate 103, so that the purpose of filtering the lubricating oil is achieved, the filtering effect is good, and the metal impurities on the surface of the sleeve pipe 204 can be quickly cleaned only by taking the sleeve pipe 204 out from the outside of the magnetic bar 203, the operation is simple, and the utility model is convenient to use, the lubricating oil only contains a small amount of impurities after being filtered by the magnetic bar 203, so that the cleaning frequency of the filter plate 103 is reduced, and the difficulty of actual operation is reduced, and the filtered lubricating oil falls below the filter plate 103 and is reused.
