The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 3 As shown, an embodiment of the utility model provides a storage tank, which includes a tank body 10 and a hopper 20. The tank body 10 has a cavity 11, and the tank body 10 has a feed port 12 and a discharge port 13 connected to the cavity 11. The feed port 12 is arranged at the top of the tank body 10, and the discharge port 13 is arranged at the bottom of the tank body 10. The hopper 20 is arranged in the cavity 11, and the upper end of the hopper 20 is arranged toward a position close to the feed port 12, and the lower end of the hopper 20 is connected to the discharge port 13. The cross-sectional size of the hopper 20 gradually decreases in the direction from the upper end of the hopper 20 to the lower end of the hopper 20, and the outer edge of the upper end of the hopper 20 is connected to the inner wall of the tank body 10 to divide the cavity 11 into a storage cavity and a accommodating cavity, and a support structure 30 located in the accommodating cavity is arranged on the outer wall of the hopper 20.

[0030] The storage tank provided in the present embodiment includes a tank body 10 and a hopper 20. A cavity 11 is provided in the tank body 10, and the hopper 20 is arranged in the cavity 11. The cavity 11 is divided into a storage cavity and a accommodating cavity by connecting the outer edge of the upper end of the hopper 20 with the inner wall of the tank body 10. A feed port 12 and a discharge port 13 connected with the cavity 11 are provided on the tank body 10, so that the material is discharged into the storage cavity through the feed port 12, and the transverse cross-sectional size of the hopper 20 gradually decreases in the direction from the upper end of the hopper 20 to the lower end of the hopper 20, and then the lower end of the hopper 20 is connected with the discharge port 13. In this way, when the material needs to be unloaded, the discharge port 13 is opened to facilitate the discharge of the material in the hopper 20 from the storage cavity, so as to facilitate the discharge. Among them, in order to facilitate the placement of the hopper 20 in the cavity 11 of the tank body 10, a support structure 30 is provided on the outer wall of the hopper 20, so as to facilitate the use of the support structure 30 to improve the structural strength of the hopper 20. The support structure 30 can also be directly welded to the outer wall of the hopper 20, and then the outer edge of the upper end of the hopper 20 is connected to the inner wall of the tank body 10, so that there is no need for the staff to weld a support plate between the tank body 10 and the hopper 20. This not only makes it easy to ensure the structural strength of the hopper 20, but also makes it easy to weld the tank body 10 and the hopper 20, which is convenient for the staff to perform welding operations and can also improve the structural reliability and practicality of the storage tank.

[0031] like Figures 1 to 3 As shown, the hopper 20 includes a hopper body 21 and a fan-shaped plate 22, a portion of the upper edge of the hopper body 21 is connected to the inner side wall of the tank body 10, a first end of the fan-shaped plate 22 is connected to the remaining upper edge of the hopper body 21, a second end of the fan-shaped plate 22 is connected to the inner end wall of the tank body 10, and the shape of the second end of the fan-shaped plate 22 is adapted to the shape of the inner wall of the tank body 10.

This is convenient for the staff to operate, and there is no need to weld the tank body 10, the support plate and the hopper 20 into the accommodating cavity when the hopper 20 is placed into the tank body 10, which makes welding convenient while ensuring the structural strength of the hopper 20.
