Description

Technical Field

[0001] The present application relates to a liquid tank truck, and in particular to an anti-vortex device when the liquid tank truck is unloading. Background Art

[0002] In order to unload cleanly and with less residue, liquid tank trucks are generally equipped with sedimentation tanks. However, when unloading, the liquid in the tank body flows quickly through the sedimentation tank, which will generate vortices in the sedimentation tank, which will cause the following problems: 1. When a vortex is generated in the sedimentation tank, when there is still a small amount of liquid in the tank body, the pipeline will first expel air until the vortex disappears, and then the liquid will be discharged again. In this way, when the air is discharged, the unloading personnel often think that the liquid in the tank body has been discharged, and thus close the discharge valve, resulting in residual liquid in the tank body. 2. The unclean liquid discharged will remain in the tank body and pipeline for a long time, which may corrode the tank body and pipeline, causing the tank body and pipeline to rust, resulting in problems such as reducing the service life of the vehicle. Summary of the invention

[0003] The technical solution of the utility model is: an anti-vortex device for unloading a liquid tank truck, which comprises a tank body and a sedimentation tank arranged at the bottom of the tank body, the anti-vortex device is fixedly installed above the sedimentation tank, the anti-vortex device is a square box structure with an opening at the bottom, and each panel thereof is provided with a leakage hole, the sedimentation tank is provided with a liquid outlet pipe, and the liquid outlet pipe is connected to a quick interface through a ball valve.

[0004] In order to prevent the liquid outlet pipe from bypassing the auxiliary beam and also to achieve a better fixing effect of the liquid outlet pipe, the liquid outlet pipe passes through the auxiliary beam at the bottom of the tank body.

[0005] The beneficial effects of the utility model are:

[0006] 1. The liquid in the tank reaches the sedimentation tank through the leakage hole on the anti-vortex device. The liquid flow rate is stable and no vortex is generated, ensuring that the liquid can be completely discharged and avoiding liquid residue in the tank and pipeline, which will cause rust and corrosion of the tank and pipeline and reduce the service life of the vehicle.

[0007] 2. The utility model has a simple structure and is also conducive to large-scale production. It increases the stability of liquid discharge without residue, while increasing the service life of the tank and pipelines and reducing user costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the structure of the utility model.

[0009] In the figure: tank body 1, anti-vortex device 2, leakage hole 3, sedimentation tank 4, liquid outlet pipe 5, ball valve 6, quick interface 7, subbeam 8. DETAILED DESCRIPTION

[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0011] exist Figure 1 In the present invention, an anti-vortex device is provided for unloading a liquid tank truck, and its composition includes a tank body 1 and a sedimentation tank 4 arranged at the bottom of the tank body 1, and its characteristic is that an anti-vortex device 2 is fixedly installed above the sedimentation tank 4, and the anti-vortex device 2 is a square box structure with an opening at the bottom, and each panel thereof is provided with a leakage hole 3, and a liquid outlet pipe 5 is provided on the sedimentation tank 4, and the liquid outlet pipe 5 is connected to a quick interface 7 through a ball valve 6.

[0012] Furthermore, the liquid outlet pipe 5 passes through the sub-beam 8 at the bottom of the tank body 1 .

[0013] An anti-vortex device 2 is installed in the tank body 1. The anti-vortex device 2 is a box-shaped structure with an opening on the bottom surface. Each panel is provided with a leakage hole 3. The anti-vortex device 2 covers the sedimentation tank 4 at the bottom. The bottom of the sedimentation tank 4 is connected with a liquid outlet pipe 5 through the subbeam 8 and the ball valve 5. At this time, the ball valve 5 is opened, and when the liquid in the tank body 1 reaches the sedimentation tank 3 after passing through the anti-vortex device 2, the liquid will not generate a vortex, so that the liquid can flow out stably and be discharged more cleanly. The liquid will not remain in the tank body 1 and the liquid outlet pipe 5, thereby ensuring that the liquid can be discharged cleanly and efficiently, avoiding rust and corrosion of the tank body 1 and the liquid outlet pipe 5, increasing the service life of the vehicle, and reducing the user's use cost.

[0014] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
