[0022] In order to more clearly understand the technical means of the utility model, and can be implemented according to the content of the specification, the specific embodiments of the utility model are further described in detail below, the following examples are used to illustrate the utility model, but not to limit the scope of the utility model.
[0023] As Figure 1 Indicated, the utility model discloses a kind of maintenance-free quantitative mixers 2, for realizing the sufficient contact of oil product and adsorbent and uniform mixing, to reduce the burden of subsequent bleaching tower, make bleaching tower can more efficiently complete fine bleaching work, improve bleaching effect.
[0024] The quantitative mixer 2 includes quantitative tank 1, mixer 2 and controller, the quantitative tank 1 is equipped with adsorbent feed inlet 3 and crude oil oil inlet 4, the feed inlet 3 and oil inlet 4 of the quantitative tank 1 are connected with adsorption tower and crude oil tank respectively by pipeline.The controller is electrically connected with the first electromagnetic valve arranged at the adsorbent feed inlet 3 and the second electromagnetic valve arranged at the crude oil oil inlet 4 respectively, for controlling the feed quantity of adsorbent and crude oil.
[0025] In the embodiment, adsorption tower and crude oil tank are respectively equipped with material level sensor for monitoring adsorbent material level and liquid level sensor for real-time feedback of crude oil liquid level, the material level sensor and the liquid level sensor are electrically connected with the controller, the first electromagnetic valve and the second electromagnetic valve are controlled by the controller based on material level sensor and liquid level sensor signal, to realize quantitative proportioning of adsorbent and crude oil.And by opening and closing control to first electromagnetic valve, to realize the quantitative addition of adsorbent, by opening and closing control to second electromagnetic valve, to ensure that the crude oil measured meets the bleaching requirement.
[0026] Flange 5 is respectively installed at the discharge pipe opening of the quantitative tank 1 and the feed pipe opening of the mixer 2, and the quantitative tank 1 and the mixer 2 are connected by two flanges 5.The connection through flange 5 can ensure the reliable connection of mixer 2 and quantitative tank 1, avoid the leakage of mixed material, and facilitate disassembly and maintenance.
[0027] Further, the crude oil inlet 4 is arranged at the top of the metering tank 1, away from the falling path of the mixture. The high design of the crude oil inlet 4 avoids the accumulation of the mixture to block the outlet, at the same time, in order to disperse the crude oil, make the crude oil more evenly distributed in the metering tank, and promote the preliminary mixing of the crude oil and the adsorbent, improve the efficiency and effect of the subsequent mixing process, at the same time, avoid the direct impact of the crude oil on the bottom of the metering tank, the metering tank 1 is provided with a tray 6, as shown in Figure 2
[0028] Further, the bottom of the metering tank 1 is provided with a conical flow guide ring 7, which guides the mixture into the outlet of the metering tank 1, avoids the accumulation of the mixture at the bottom of the metering tank 1, and improves the controllability of the material flow.
[0029] The mixer 2 is provided with a support 8 along the height direction, as shown in Figures 3 to 5 The support 8 is alternately arranged with solid discs 9 and hollow discs 10, in this embodiment, each hollow disc 10 and solid disc 9 is coaxially arranged, and the outer diameter of the hollow disc 10 is larger than that of the solid disc 9. When the mixture falls through the outlet and inlet, it first hits the solid disc 9, and then scatters along the side of the solid disc 9; then, the scattered mixture falls along the side of the solid disc 9 to the hollow disc 10, and then flows through the hollow area 102 of the hollow disc 10 to realize the dynamic adjustment of the flow rate and flow direction, further promoting the mutual intermingling and mixing of the mixture.
[0030] Further, a splash-proof spacing H is provided between the uppermost solid disc 9 and the top of the mixer 2. On the one hand, this spacing H can effectively prevent the mixture from splashing due to the impact of the falling force, and then splashing to the outlet of the metering tank 1 and the inlet of the mixer 2 and causing the pipe to be blocked, affecting the normal entry and exit of the mixture, and reducing the working efficiency of the mixer 2. On the other hand, this spacing H can effectively prevent the mixture from surging upwards. When the material cannot flow downward in time, it will accumulate at the top of the mixer 2, and then cause the mixture to surge upwards. Once the mixture surges upwards, it may gradually reduce the outlet of the metering tank 1, affecting the conveying flow and flow rate of the material from the metering tank 1 to the mixer 2.
[0031] In order to further improve the mixing effect of the mixture, the side of the solid disc 9 and the hollow disc 10 is respectively provided with a first notch 91 and a second notch 101 recessed in the radial direction, which provides an additional flow channel for the mixture, increases the diversity of the flow path, makes the mixture more dispersed during the falling process, increases the contact area between the mixture, and thus improves the mixing efficiency.
[0032] Further, the second notch 101 has a depth greater than the first notch 91 in the radial direction, the first notch 91 ensures that the mixed material spreads from the center of the disc to the side and provides an additional falling channel for the mixed material; the second notch 101 makes the mixed material not concentrate in the hollow area 102, but fall along the multiple second notches 101, so that the distribution of the mixed material in the lower space is more uniform.
[0033] The mixed material is alternately acted on by the solid disc 9 and the hollow disc 10, and the design of the first notch 91 and the second notch 101, so that the mixed material undergoes complex physical processes such as collision, scattering, interpenetration and the like for multiple times, realizes uniform mixing, and provides a high-quality, uniform mixed material basis for subsequent process links.
[0034] The above is only the preferred embodiment of the present application, and is not used to limit the present application, it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, can make a number of improvements and modifications, these improvements and modifications should also be considered as the protection scope of the present application.
