[0002] Storage tanks are containers used to store large quantities of various liquids. They are widely used in the fields of petroleum, chemical industry, grain and oil, food, fire protection, transportation, metallurgy, and national defense. With the continuous development of the storage tank industry, more and more industries and enterprises are using storage tanks, and the types of storage tanks are also increasing.

[0003] Existing storage tanks are mainly steel tanks. Although steel tanks have undergone some anti-corrosion treatment, when corrosive liquids need to be stored for a long time, the corrosion resistance of the tanks is limited, resulting in a short service life and failure to meet usage requirements. Utility Model Content

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A thermoplastic plastic lined steel metal composite tank includes a tank body, the top end of the tank body is connected to a liquid inlet pipe, the bottom end of the tank body is connected to a liquid outlet pipe, a support bracket is provided on the circumference of the tank body, and a liquid level alarm mechanism is provided inside the tank body. The tank body includes a thermoplastic resin lining layer, an interface layer and a metal reinforcement layer arranged in sequence from the inside to the outside, and the thermoplastic resin lining layer and the metal reinforcement layer are bonded to each other through the interface layer.

[0007] Furthermore, the material of the metal reinforcement layer is carbon steel, and the outer surface of the metal reinforcement layer is also provided with an outer anti-corrosion layer.

[0010] Furthermore, a liquid outlet valve is provided on the liquid outlet pipe.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0012] 1. The present invention comprises a tank body, wherein the top end of the tank body is connected to a liquid inlet pipe, the bottom end of the tank body is connected to a liquid outlet pipe, a support bracket is provided on the circumference of the tank body, and a liquid level alarm mechanism is provided within the tank body. The tank body comprises, arranged from the inside to the outside, a thermoplastic resin lining layer, an interface layer, and a metal reinforcement layer, the thermoplastic resin lining layer and the metal reinforcement layer being bonded together via the interface layer. With this arrangement, the liquid inlet pipe is used to allow liquid to enter the tank body, the liquid outlet pipe is used to discharge the liquid to be stored, the support bracket is used to securely support the tank body, and the liquid level alarm mechanism is used to monitor the liquid level. When the liquid stored in the tank body reaches a preset maximum limit, the liquid level alarm mechanism sounds an alarm, prompting staff to promptly stop adding liquid. The tank body is divided into three layers. The metal reinforcement layer ensures the strength of the tank structure and provides support for the entire composite tank; the interface layer is used to connect the thermoplastic resin lining layer and the metal reinforcement layer to ensure the continuity of the tank structure; the thermoplastic resin lining layer has excellent corrosion resistance and light weight. Even if the tank body stores corrosive liquids, it can ensure the service life of the tank body, effectively solving the problems of poor corrosion resistance and short service life of existing storage tanks.

[0013] 2. In the present invention, the metal reinforcement layer is made of carbon steel, and an outer anti-corrosion layer is provided on the outer surface of the metal reinforcement layer. This outer anti-corrosion layer improves the corrosion resistance of the outer surface of the metal reinforcement layer, preventing the tank from being corroded externally and thus shortening its service life.

[0014] 3. In the present invention, the metal reinforcement layer is made of stainless steel. This configuration provides excellent oxidation resistance and corrosion resistance, which can prevent the tank from being corroded externally and shortening its service life.

[0015] 4. In the present invention, the liquid level alarm mechanism includes a sensing base disposed within the tank body, a float trigger assembly disposed below the sensing base, and a guide rod with a limit sleeve mounted thereon. The guide rod is movable up and down within the limit sleeve, the limit sleeve being connected to the sensing base via an L-shaped connecting rod. The lower end of the guide rod is connected to a float, and the upper end of the guide rod is connected to a terminal. The sensing groove of the sensing base is located above the terminal, and the sensing base is electrically connected to an alarm. With this arrangement, when the liquid level in the tank rises to the float, the float is acted upon by buoyancy and moves upward. Because the limit sleeve limits the guide rod, ensuring that the float rises, the terminal at the upper end of the guide rod moves vertically upward. When the liquid level in the tank gradually rises to a preset maximum limit, the terminal contacts the sensing groove of the sensing base, and the sensing base transmits a contact signal to an external alarm, triggering the alarm, allowing personnel to promptly stop liquid delivery.

[0016] 5. In the present invention, a liquid outlet valve is further provided on the liquid outlet pipe. Through this arrangement, the liquid outlet valve is convenient for opening and closing the liquid outlet pipe, making it convenient for staff to operate the liquid outlet.

[0032] Furthermore, a liquid outlet valve is provided on the liquid outlet pipe.

[0033] During the implementation of the present invention, the liquid inlet pipe is used to allow the liquid to be stored to enter the tank body, the liquid outlet pipe is used to discharge the liquid to be stored, the support bracket is used to fix and support the tank body, and the liquid level alarm mechanism is used to monitor the liquid level. When the liquid stored in the tank body reaches the preset maximum upper limit, the liquid level alarm mechanism issues an alarm prompt, and the staff can stop the liquid in time. The tank body is divided into a three-layer structure. The metal reinforcement layer ensures the strength of the tank body structure and provides support for the entire composite tank; the interface layer is used to connect the thermoplastic resin lining layer and the metal reinforcement layer to ensure the continuity of the tank body structure; the thermoplastic resin lining layer has excellent corrosion resistance and is lightweight.

The sensing groove of the sensing base is located above the end head, and the sensing base is electrically connected to an alarm. With this arrangement, when the liquid level in the tank rises to the float, the float moves upward due to buoyancy. Because the limit sleeve can limit the guide rod, ensuring that the float floats, the end head at the upper end of the guide rod moves vertically upward. When the liquid level in the tank gradually rises to a preset maximum upper limit, the end head contacts the sensing groove of the sensing base, and the sensing base transmits a contact signal to an external alarm, triggering the alarm, allowing staff to stop adding liquid in a timely manner.

When the liquid stored in the tank body reaches a preset maximum limit, the alarm mechanism sounds an alarm, prompting personnel to promptly stop adding liquid.
