Description

Technical Field

[0001] The present application relates to a glass fiber reinforced plastic container, and in particular to a glass fiber reinforced plastic tank with a gas stirring function. Background Art

[0002] FRP tanks are a common industrial equipment, widely used in fermentation, chemical, pharmaceutical and water treatment fields. In order to improve the fermentation efficiency, FRP tanks usually need to be equipped with stirring devices to ensure that the materials are fully mixed and reacted in the tank. Stirring technology is mainly divided into two categories: mechanical stirring and gas stirring. Among them, gas stirring is widely used in practical applications due to its advantages such as high stirring uniformity, relatively simple structure and large stirring area.

[0003] The gas stirring devices in the prior art mostly adopt a fixed ordinary pipeline structure, and its stirring gas outlet is a simple hole-shaped or open-type design. Although this design can meet the stirring needs to a certain extent, the stirring effect is limited because the gas outlet is fixed and unevenly distributed. Specifically, the fixed ordinary pipeline structure makes the gas distribution in the tank not uniform, especially when the tank body is large or complex in shape, it is easy to form a stirring dead angle, resulting in insufficient material mixing. Due to the simple structure of the gas outlet, the diffusion range of the gas in the tank after being sprayed out is limited, making it difficult to achieve effective stirring of the materials in the entire tank body.

[0004] In addition, the stirring gas outlet of the ordinary pipeline structure is easily blocked by solid materials or sediments in the tank due to its large opening, resulting in a decrease in the stirring effect or even cessation of work. Utility Model Content

[0005] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a FRP tank with a gas stirring function. The FRP tank uses a Venturi structure at the pipe near the stirring gas outlet and makes the outlet a spinning structure to improve the stirring uniformity and stirring range.

[0006] To achieve the above-mentioned purpose, the present application discloses a glass fiber reinforced plastic tank with gas stirring function, comprising a tank body, a fixed air pipe extending into the tank body, a self-spinning air pipe and a controller, wherein several fixed air pipes are inserted into the tank body from outside the tank body with different depths, so that the exhaust ports of each fixed air pipe are staggered in the height direction of the tank body; the fixed air pipe is provided with a Venturi channel near the exhaust port, and the Venturi channel is used to accelerate and diffuse the airflow; each fixed air pipe is connected to an air source at one end outside the tank body, and an electric-controlled air valve is installed on the pipeline connected to the air source, and each electric-controlled air valve is connected to the controller and is controlled to open and close by the controller; at least one self-spinning air pipe extends into the tank body from outside the tank body, and the self-spinning air pipe is also connected to the air source outside the tank body; the self-spinning air pipe is divided into a fixed section and a rotating head that rotates with the fixed section in the tank body, and an exhaust port is installed on the rotating head, and the rotating head is driven to rotate by the exhaust pressure of the exhaust port.

[0007] Furthermore, a liquid level sensor connected to the controller is provided in the tank body, and the liquid level information in the tank body is sent to the controller via the liquid level sensor.

[0008] Furthermore, the exhaust directions of the fixed air pipes are different.

[0009] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0010] 1. By using the combination of fixed air pipe and self-rotating air pipe, the exhaust ports are distributed at different heights and directions to provide multi-directional stirring.

[0011] 2. The Venturi channel of the fixed air pipe accelerates the airflow, so that the gas outlet spin structure enhances the diffusion effect and realizes uniform stirring of the material in the tank.

[0012] 3. The rotating head of the self-spinning air pipe can prevent solid materials from blocking the exhaust port, thereby improving the mixing efficiency and the reliability of the gas mixing function.

[0013] 4. The Venturi channel accelerates the airflow to prevent sediment from blocking the outlet.

[0014] 5. The controller is connected to the electric control valves on each fixed air pipe to realize the opening and closing control of the fixed air pipes at different positions and intelligent stirring. The liquid level sensor transmits the tank liquid level information to the controller, so that the stirring device can stir reasonably according to the liquid level to prevent excessive stirring.

[0015] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1 , 2 As shown, this embodiment provides an exemplary structure of a fiberglass tank with a gas stirring function, including a tank body 1, a fixed gas pipe 2, a self-spinning gas pipe 3 and a controller 8.

[0023] Specifically, the tank body 1 is made of high-strength fiberglass, which is corrosion-resistant, light-weight and structurally stable, and is suitable for fermentation, chemical industry, pharmaceutical industry, water treatment and other fields. A plurality of fixed air pipes 2 and a self-spinning air pipe 3 are installed inside the tank body 1 to achieve efficient stirring of the material in the tank.

[0024] In this embodiment, the fixed air pipe 2 is inserted from the outside of the tank body 1 into the inside of the tank body 1, and the exhaust ports 4 of different fixed air pipes 2 are staggered in the height direction of the tank body 1. The exhaust ports 4 face different directions to ensure the uniformity of stirring and the effect of no dead angle. A Venturi channel 5 is provided at the part of each fixed air pipe 2 near the exhaust port 4, and the airflow is accelerated and diffused through the Venturi effect, so that the airflow jet presents a spin structure, thereby enhancing the uniformity of stirring and the diffusion range.

[0025] In this embodiment, one end of the fixed gas pipe 2 outside the tank 1 is connected to a gas source (not shown in the figure), and the gas source is a standard gas compression system to ensure the stability of gas supply. An electric-controlled gas valve 6 is installed on the pipeline connecting each fixed gas pipe 2 to the gas source to control the opening and closing of the gas flow. All the electric-controlled gas valves 6 are connected to the controller 8 through wires and are uniformly managed by the controller 8.

[0026] In this embodiment, the self-spinning air pipe 3 extends from the outside of the tank body 1 into the inside of the tank body 1, and is divided into two parts: a fixed section 3a and a rotating head 3b. The rotating head 3b realizes rotational cooperation with the fixed section 3a through a rotating cooperation structure, and can rotate along the fixed section 3a, so that the airflow presents a spinning structure when it is ejected. A plurality of exhaust ports 3c are provided on the rotating head 3b, and 360-degree all-round uniform stirring is achieved through rotational motion. The self-spinning air pipe 3 is also connected to the gas source, and its gas injection direction can realize uniform stirring without dead angles according to the rotation of the rotating head 3b.

[0027] More specifically, the rotational matching structure of the self-spinning air pipe 3 includes a rotational bearing and a rotational seal. It should be understood that the above-mentioned rotational matching structure belongs to the known technology in the art, so it will not be explained and described in more detail.

[0028] In order to realize controllable stirring, a control system is composed of a controller 8, an electric-controlled air valve 6 and a liquid level sensor 7. The controller 8 is connected to the electric-controlled air valve 6 of the fixed air pipe 2, and can realize independent or combined control of multi-channel gas stirring. The controller 8 is also connected to the liquid level sensor 7 installed in the tank body 1 to receive the liquid level information in the tank body 1. According to the different liquid levels of the materials in the tank body 1, the controller 8 adjusts the gas flow rate of the exhaust port of each fixed air pipe 2 through the control of the electric-controlled air valve 6, and combines the stirring effect of the self-rotating air pipe 3 to provide a stirring method adapted to different liquid levels.

[0029] Although exemplary embodiments of the present disclosure have been described, it will be apparent to those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure.
