Abstract
Description
Technical Field
[0001] The utility model relates to a circulating oil pool for an oil injection pipeline, belonging to the technical field of emulsified asphalt production. Background Art
[0002] In the asphalt processing process, crude oil needs to be processed, and after processing, various required asphalts (such as colored asphalt, emulsified asphalt, waterproof asphalt, cold patch asphalt) will be formed. Figure 3 As shown, oil is injected through an oil pipeline, which is usually arranged horizontally at high altitude, with a road for vehicles traveling below. An oil injection docking valve 11 is opened on the upper oil pipeline facing the road. When a transport vehicle passes by, the pumping pipeline is connected to the oil injection docking valve 11 to achieve oil injection. However, it is found during use that, firstly, there are certain risks for personnel construction in docking pipelines at high altitude; secondly, after oil injection, after the valve is closed, some oil flows to the road below; thirdly, the oil injection efficiency is not high. Simply pumping by vehicles may result in low oil pressure, which reduces the processing capacity of the back-end equipment. Utility Model Content

[0005] The oil pool is provided with a matching cover plate I, the cover plate I is provided with an oil filling port extending upward, and a cover plate II is also provided on the oil filling port.
[0006] Furthermore, the oil delivery pump is arranged with one in use and one in reserve.
[0007] Furthermore, a support frame is arranged at the lower end of the oil pump, and the oil pump is fixed on the support frame.

[0019] Example 1
[0020] like Figure 1-2 As shown, the oil pool of the oil injection pipeline described in the utility model includes an oil pool 4 for fixing on the inner side of a protective wall 7. The protective wall 7 is usually used to prevent large-scale leakage of the rear-end processing equipment, which causes large-scale pollution of the environment. Therefore, a protective wall 7 is usually built around the equipment. An oil pump 8 is connected to one end of the oil pool 4, and the output end of the oil pump 8 is connected to the oil pipeline 1. A return pipeline 2 is also arranged between the oil pipeline 1 and the oil pool 4, and a pressure relief valve 3 is installed on the return pipeline 2; the front end of the connecting pipeline of the oil pump 8 and the oil pool connecting section are installed with valves I 81 and II 82 through flanges, which are convenient for installing the pipeline on the one hand and for maintaining the oil pump 8 on the other hand. When the oil pump needs maintenance, the flange can be removed. A valve III 83 is installed between the rear end of the oil pump 8 and the oil pipeline 1 to prevent the oil in the oil pipeline 1 from flowing back after the oil pump 8 is disassembled.
[0021] The oil pool 4 is provided with a matching cover plate I5, the cover plate I5 is provided with an oil filling port extending upward, and a cover plate II6 is also provided on the oil filling port.
[0022] The oil pump 8 adopts a one-in-one-standby setting. A pair of control valves are installed at the front and rear ends of the two parallel-installed oil pumps. When the control valve of the corresponding oil pump 8 is closed, one of the oil pumps 8 can start working when it is shut down, thus completing the one-in-one-standby setting.
[0023] A support frame is arranged at the lower end of the oil pump 8, and the oil pump 8 is fixed on the support frame, and the support frame is fixed on the internal concrete floor.
[0024] The pressure relief valve 3 is installed on the lowest horizontally arranged pipeline, which is convenient for later maintenance and installation.
[0025] The height of the pressure relief pipe connected to the oil pool 4 is higher than the connecting pipe of the oil pump 8, so the oil inlet is smoother.
[0026] The cover plate I5 and the cover plate II6 are provided with handles 52 respectively, so as to facilitate opening for inspection or cleaning of the oil residue at the bottom.
[0027] Both cover plate Ⅰ5 and cover plate Ⅱ6 are provided with a downwardly extending lower edge 51 to enhance the stability of cover plate Ⅰ5 and cover plate Ⅱ6. Cover plate Ⅰ5 makes the extended lower edge 51 stuck to the upper part of the oil pool 4 to prevent cover plate Ⅰ5 from moving horizontally and vertically. The purpose of setting cover plate Ⅱ6 is basically the same as that of cover plate Ⅰ5, which will not be introduced in detail here.
[0028] Working process or working principle:
[0029] The transport vehicle is backed up to the protective wall 7, and then the cover plate II 6 is opened, and the pumping pipe is extended into the oil filling port. At this time, oil is delivered through the oil pump 8. When the oil pressure is too high and the back-end equipment cannot handle it, the pressure relief valve 3 starts to work and the reflux pipe 2 starts to reflux. The pressure relief valve 3 rarely works under normal circumstances. Usually, the processing capacity of the back-end equipment matches the supply capacity of the oil pump 8.
[0030] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up, and down, does not constitute a limitation of the present invention, but is only for the convenience of description.
