Description

Technical Field

[0001] The utility model relates to a stirring device for a horizontal storage tank, belonging to the field of multiphase system mixing. Background Art

[0002] In industrial production, horizontal storage tanks are commonly used to store liquid-phase materials. When the stored materials are multiphase systems such as liquid-liquid multiphase and liquid-solid multiphase, due to the different properties of each phase in the multiphase system, when the specific gravity differences of each phase component are large, stratification is likely to occur, resulting in uneven composition of the multiphase system. Especially in the case of storing liquid-solid multiphase, the deposition of solid-phase components generates mud, causing the effective storage volume of the storage tank to become smaller or blocked. The Chinese utility model patent with the patent number CN202122502055.0 discloses a liquid mixing and stirring device, which can achieve full mixing and stirring of liquids through mechanical stirring and air flow impact, improving the stirring efficiency.

[0003] However, the inventor of the present utility model found that the prior art has the following problems: In industry, the method of setting mechanical stirring is often used to stir the substances in the storage tank to prevent material stratification or deposition of mud. However, there are many dead zones when setting mechanical stirring on a horizontal storage tank. When the material system is corrosive, it is difficult to select materials for the stirring device. And when the material system in the storage tank needs to isolate air, the sealing structure of the mechanical stirring device is relatively complex and the cost is high. Therefore, improvement is needed. Summary of the Utility Model

[0019] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0020] The first embodiment of the present utility model relates to as Figures 1-4A stirring device for a horizontal storage tank as shown, comprising a horizontal storage tank 1, an insertion pipe interface 2, a liquid flow outlet 10, a stirring component 8 and a power component 9; the lower side of one end face of the horizontal storage tank 1 is horizontally and arrayedly connected with the insertion pipe interface 2; the surface of the horizontal storage tank 1 above the insertion pipe interface 2 is horizontally and arrayedly connected with the liquid flow outlet 10; the stirring component 8 passes through the insertion pipe interface 2 and is fixed on the inner wall of the horizontal storage tank 1; one end of the power component 9 is connected with the liquid flow outlet 10, and the other end is connected with the stirring component 8 at the insertion pipe interface 2; the stirring component 8 includes an insertion pipe 3, an insertion pipe support 4 and a branch pipe 5; the lower surface of the insertion pipe 3 is axially and arrayedly connected with the insertion pipe support 4; a sealing plate is fixedly connected to the end of the insertion pipe 3; the bottom surface of the insertion pipe support 4 is fixedly connected to the inner surface of the horizontal storage tank 1; the shape of the insertion pipe support 4 is "door"-shaped; the branch pipe 5 is misaligned and connected to the surface of the insertion pipe 3; the horizontal storage tank 1 is used to store liquid-phase materials, and the insertion pipe interface 2 is the part for installing the insertion pipe 3; the liquid flow outlet 10 is the outlet for the materials in the storage tank to circulate; the stirring component 8 is used to stir the liquid-phase materials at the bottom of the horizontal storage tank 1; the power component 9 is used to provide the liquid kinetic energy for stirring the stirring component 8.

[0021] The second embodiment of the present utility model is basically the same as the first embodiment, mainly in the scheme optimization of the power component. The power component 9 includes a pump 6, a first valve 71, a second valve 72, a third valve 73 and an external fluid access pipe 11; the liquid flow outlet 10 is connected to the first valve 71, the pump 6 and the second valve 72 in sequence through a pipeline; one end of the third valve 73 is connected to the external fluid access pipe 11, and the other end is connected to a pipeline that converges with the pipeline connected to the end of the second valve 72 and then jointly connected to the end of the insertion pipe 3; the pump 6 is used to extract liquid and provide liquid kinetic energy; the first valve 71 is mainly convenient for installation and maintenance; the second valve 72 is used to control the liquid flow rate circulating into the horizontal storage tank 1; the third valve 73 is used to control the flow rate of external liquid entering; the external fluid access pipe 11 is used to flow in external fluid.
