A first through hole is provided on the tank cover, a water passing hole is provided on the outer side wall of the lower end of the tank body, and a communicating pipe assembly is provided on the water passing hole; the air outlet of this water storage tank is opened on the tank cover, thus not affecting the strength of the tank body and making the service life longer. Moreover, the tank cover can be detached from the tank body, and the stains at the air outlet on the tank cover are easy to clean, thus saving time and effort. However, there are still problems such as low overall feeding efficiency, and after the water storage tank stores water for a long time, the water quality will be polluted, and it needs to be cleaned manually, with high labor intensity, time-consuming and laborious, and the cleaning effect is poor. In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0004] In order to overcome the above technical defects, the present utility model provides a circulating water storage tank for bio-aviation fuel raw materials to solve the problems of low water inlet efficiency and water quality pollution of the existing water storage tank.

[0005] The technical solution adopted by the present utility model is as follows: A circulating water storage tank for bio-aviation fuel raw materials includes a tank body and a tank cover. A plurality of water inlets are opened on the tank cover. A filtering mechanism is installed below the tank cover. The tank cover is connected to the tank body through a lifting device. The tank body is connected to any one of the water inlets through a return pipeline.

[0006] Specifically, water sources enter the tank cover simultaneously through a plurality of water inlets. After being filtered by the filtering mechanism, the water then enters the tank body, greatly improving the water inlet efficiency, avoiding water quality pollution, and through the return pipeline, the stored water is circulated back, so that the water quality in the tank body is circulated and filtered and homogenized, ensuring that the stored water in the tank body remains clean for a long time, and avoiding the regular cleaning of the water storage tank due to the influence of water quality pollution, sundries, etc. entering.

[0007] Further, a limiting groove is formed on the lower surface of the tank lid. The filtering mechanism includes a filter plate horizontally arranged in the limiting groove. Positioning screw holes are formed in the side walls of the filter plate opposite to each other. Locking bolts are inserted through the groove walls of the limiting groove, and the locking bolts are arranged in one-to-one correspondence with the positioning screw holes. The screw rods of the locking bolts are threadedly connected to the corresponding positioning screw holes.

[0008] Specifically, impurities and particles in the water are filtered by the filter plate to ensure the cleanliness of the circulating water. And the filter plate can be quickly installed and disassembled through the locking bolts, which increases the practicability of the device.

[0009] Further, the lifting device includes fixed seats arranged opposite to each other. The fixed seats are fixedly connected to the tank body. A sliding groove is formed along the height direction of the fixed seats. A connecting block is slidably connected in the sliding groove. The outer end of the connecting block is fixedly connected to the tank lid, and the inner end of the connecting block is connected to a driving device.

[0010] Specifically, the driving device drives the connecting block to move in the sliding groove, thereby driving the tank lid to separate from / close to the tank body, which is convenient for timely cleaning the tank mouth and the filter plate on the tank lid and keeping the water quality in the tank body from being polluted.

[0011] Further, the fixed seat is of a hollow structure. The driving device includes a motor arranged in the fixed seat. The output end of the motor vertically extends upward and is connected with a lead screw. A sliding block is sleeved on the lead screw. The sliding block is threadedly connected to the lead screw. The sliding block is fixedly connected to the inner end of the connecting block.

[0012] Specifically, the rotation of the lead screw can drive the sliding block to move up and down, thereby driving the connecting block to move along the length direction of the sliding groove, and further driving the tank lid to lift, which is convenient for cleaning the tank mouth and the filter plate on the tank lid.

[0013] Further, the return pipeline includes a return pipe. One end of the return pipe is fixedly communicated with the bottom of the tank body. The other end of the return pipe is detachably connected to the water inlet. A return pump and a water quality detector are arranged on the return pipe.

[0014] Specifically, the return pipe can be connected to any water inlet according to the situation to clean the water inlet, which is time-saving and labor-saving. And by monitoring the water quality of the stored water in the circulating return, the filtering situation of the filtering mechanism can be judged, so as to replace the filter plate in time and further improve the water quality cleanliness in the tank body.

[0015] Further, there are four water inlets, and the four water inlets are arranged in pairs opposite to each other.

[0016] Further, a water outlet pipe is provided at the bottom of the tank body, and a three-way solenoid valve is installed on the water outlet pipe. The three-way solenoid valve, the reflux pump, and the water quality detector are all electrically connected to the controller.

[0017] Specifically, the water quality in the tank body is monitored by the water quality detector. When the water quality is poor, the reflux pump is started to perform secondary filtration and homogenization on the water quality. When the water quality is qualified, the stored water is discharged from the water outlet pipe for production.

[0018] Further, it also includes an annular support base. The inner ring surface of the annular support base is fixedly connected to the lower part of the tank body, and support legs are installed on the annular support base.

[0019] Beneficial effects: Compared with the prior art, the utility model can simultaneously introduce the water separated from different biodiesel raw materials into the interior of the water storage tank through multiple water inlets, improving the feeding efficiency and reducing the pressure burden on a single water inlet. By setting up a filtering mechanism, impurities and particles in the water can be filtered to ensure the cleanliness of the circulating water. And through the reflux pipeline, the stored water is circulated and refluxed, enabling the water quality in the tank body to be filtered and homogenized cyclically, ensuring that the stored water in the tank body remains clean for a long time, reducing the frequency of cleaning the water storage tank due to the influence of water quality pollution, sundries, etc. entering, with strong practicability and broad application prospects.
