[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0021] like Figure 1-4As shown, the reflux device for filling edible oil comprises a crude oil tank 1, a filling tank 2 and a sedimentation and filtering mechanism 3. The oil outlet of the crude oil tank 1 is connected to the oil inlet of the filling tank 2 through an oil delivery pipeline 4. The oil delivery pipeline 4 can be a combination of an oil pump and a pipeline, which can transport the edible oil in the crude oil tank 1 into the interior of the filling tank 2. The lower part of the filling tank 2 is connected to the lower part of the sedimentation and filtering mechanism 3 through an oil return pipeline 6. The oil return pipeline 6 comprises a pipeline connecting the lower part of the filling tank 2 and the lower part of the sedimentation and filtering mechanism 3. A valve and a check valve are installed on the pipeline, so that the oil return pipeline 6 can flow the remaining edible oil in the filling tank 2 into the interior of the sedimentation and filtering mechanism 3 after the filling tank 2 is used. The upper part of the sedimentation and filtering mechanism 3 and the upper part of the crude oil tank 1 are connected through an oil return hose 5. After the sedimentation and filtering mechanism 3 precipitates the edible oil, the precipitated edible oil can be transported into the interior of the crude oil tank 1 through the oil return hose 5 to complete the reflux of the edible oil.
[0022] like Figure 1-3 As shown, the core of the technical solution is the improvement of the structure of the sedimentation filtering mechanism 3, which is specifically that the sedimentation filtering mechanism 3 includes a container 7, the lower part of the container 7 is connected to the oil return pipeline 6, the upper part of the container 7 is equipped with an oil pump 8 connected to the oil return hose 5, the input end of the oil pump 8 is connected to the oil suction head 10 located inside the container 7 through a connecting hose 9, and the lower end of the oil suction head 10 is provided with an oil inlet. When the oil inlet of the oil suction head 10 is located inside the edible oil in the container 7, the oil pump 8 is started to pump the edible oil The container 7 is provided with an automatic height adjustment mechanism connected to the oil suction head 10 for adjusting the height of the oil suction head 10 so that the oil inlet of the oil suction head 10 is always located near the liquid surface inside the edible oil, and the edible oil near the liquid surface is sucked. Since the purity of the edible oil gradually increases with the height of the edible oil after clarification, the oil suction head 10 in the technical solution always sucks oil from a position near the liquid surface inside the edible oil, thereby effectively reducing impurities that flow back into the crude oil tank 1 along with the edible oil.
[0023] Among them, one structure of the automatic height adjustment mechanism includes an electric push rod and an infrared ranging device. The electric push rod is vertically fixedly connected to the upper side of the container 7, and the output end of the container 7 is fixedly connected to the oil suction head 10, so that the height of the oil suction head 10 can be controlled through the container 7. The infrared ranging device is fixedly connected to the upper end of the container 7, and is used to measure the liquid level of the edible oil in the container 7. After the measurement is completed, the electric push rod is controlled by the controller to move automatically.
[0024] Among them, the automatic height adjustment mechanism can also be Figure 2 As shown, it includes a buoyancy member located inside the container 7, and the oil suction head 10 is installed on the buoyancy member, so that under the action of the buoyancy member, the oil suction head 10 can automatically move following the change of the liquid level. Its structure is relatively simple and the failure rate is low.
[0025] like Figure 3-4 As shown, the buoyancy member includes a buoyancy ring 11 vertically slidably connected to the inside of the container 7, and a buoyancy plate 12 is fixedly connected to the inside of the buoyancy ring 11. The oil suction head 10 is assembled on the buoyancy plate 12. At this time, the oil suction head 10 can be horizontally limited by the buoyancy ring 11 and the buoyancy plate 12, so that the oil suction head 10 can only move vertically stably, reducing the kinetic energy amplitude of the oil suction head 10 when sucking oil.
[0026] Since some impurities may float on the liquid surface, in order to further reduce impurities, the oil suction head 10 is vertically slidably connected to the buoyancy plate 12, and an electric height adjustment structure is fixedly connected to the buoyancy plate 12. The oil suction head 10 is installed on the electric height adjustment structure. At this time, the height of the oil suction head 10 can be adjusted by adjusting the height of the oil suction head 10 through the electric height adjustment structure, so as to adjust the distance between the oil inlet of the oil suction head 10 and the liquid surface, thereby reducing the suction of impurities on the liquid surface by the oil suction head 10.
[0027] like Figure 4 As shown, the electric height adjustment structure includes a vertical bracket 13 fixedly connected to the upper side of the buoyancy plate 12, the upper end of the vertical bracket 13 is fixedly connected to a transmission motor 14, the output end of the transmission motor 14 is fixedly connected to a vertically arranged screw rod 15, and the vertical bracket 13 is vertically slidably connected to a connecting frame 16 fixedly connected to the oil suction head 10, and the screw rod 15 and the connecting frame 16 are threadedly connected. At this time, by starting the transmission motor 14, the screw rod 15 can be driven to rotate, and the screw rod 15 drives the connecting frame 16 to move vertically, so that the height of the oil suction head 10 can be adjusted, and after the adjustment is completed, the position of the oil suction head 10 can be locked by the thread.
[0028] like Figure 3 As shown, a filter element 17 located at the lower side of the oil suction head 10 and the buoyancy ring 11 is installed in the lower part of the interior of the container 7. The filter element 17 can be a filter screen or other filtering structures. At this time, the filter element 17 can filter larger floating impurities and reduce the impurities floating on the liquid surface, thereby effectively reducing the suction of impurities on the liquid surface by the oil suction head 10.
[0029] The working principle of the utility model is: the edible oil in the filling tank 2 is returned to the interior of the sedimentation and filtering mechanism 3 through the oil return pipeline 6 to clarify the edible oil;
[0030] At the same time, the height of the oil suction head 10 is adjusted by the automatic height adjustment mechanism so that the oil inlet of the oil suction head 10 is always located at a position close to the liquid surface inside the edible oil;
[0031] Then, the oil pump 8 is started to suck the edible oil near the liquid surface, so that the edible oil flows back into the crude oil tank 1, thereby completing the reflux of the edible oil.
[0032] In summary, the technical solution automatically adjusts the height of the oil suction head 10 by setting an automatic height adjustment mechanism, so that the oil can always be sucked from a position close to the liquid surface inside the edible oil, thereby effectively reducing the impurities that flow back into the crude oil tank 1 along with the edible oil.
[0033] The above is only a preferred implementation of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
