Description

Technical Field

[0001] The utility model relates to the technical field of flow guide devices, in particular to a flow guide device that is easy to maintain. Background Art

[0002] The main process of wet stirring and mixing operation is to place the liquid in a container and use a rotating impeller (agitator) immersed in the liquid or other means to stir the fluid to achieve uniform mixing between two or more materials and accelerate the heat and mass transfer process. The device that completes this mixing operation process is called a wet stirring mixing reactor. The vertical mechanical stirring tank (barrel) is the most widely used type of stirring tank in the wet smelting production of non-ferrous metals. The vertical mechanical stirring tank generally consists of three parts: a stirring device, a tank body, and stirring accessories. Currently, large-scale industrial wet smelting mostly adopts a continuous feeding and discharging method. In order to enhance the mixing or reaction effect of the materials and ensure the reaction time of the materials in the reactor, a diversion device is provided in the reactor to achieve the purpose of controlling the flow field. The diversion device of the general reactor is integrated with the reactor. When the diversion device is blocked, the cleaning and dredging operation is limited.

[0003] Therefore, how to design a diversion device that is easy to maintain is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0004] The utility model provides a flow guiding device which is easy to maintain, and solves the technical problem that the flow guiding device of the existing wet stirring mixing reactor is difficult to clear and maintain.

[0005] The utility model solves the above technical problems with the following technical solutions: a flow guide device that is easy to maintain and can be detachably inserted into a mixing tank, comprising: a flow guide pipe, a flange and a top sealing plate.

[0006] A plug hole is provided at the top of the stirring tank; the guide tube is movably inserted into the plug hole and its top end extends out of the stirring tank, and a guide hole is provided on the upper side tube wall extending into the stirring tank; the flange is fixed on the outer peripheral side of the guide tube extending out of the stirring tank; the top sealing plate is detachably buckled at the opening at the top end of the guide tube.

[0007] The beneficial effect of the utility model is that the guide pipe is first inserted into the mixing tank through the plug hole, and then the flange is fixed on the outer peripheral side of the guide pipe extending out of the mixing tank. Since the flange is detachably connected to the top of the mixing tank, the convenience of removing the guide pipe from the mixing tank can be improved, so that when unclogging the guide pipe, the guide pipe can be removed from the mixing tank, overcoming the limitation of the narrow internal space of the mixing tank that is difficult to operate, and improving the maintainability of the guide pipe.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, it also includes a lifting assembly, which includes a hanging plate and fixing bolts. The flange plate is provided with a plurality of threaded holes A spaced apart along its circumference on the disk surface corresponding to the outer periphery of the guide pipe; the hanging plate is located above the top sealing plate and is provided with threaded holes B on the plate surface corresponding to both sides of the guide pipe, and the two threaded holes B can be arranged opposite to the plurality of threaded holes A; there are two fixing bolts, which are respectively screwed into the two threaded holes B and fixed on the corresponding two threaded holes A.

[0010] Adopt above-mentioned further beneficial effect is:

[0011] 1. Use fixing bolts to fix the top of the hanging plate to the flange, which can press the top sealing plate tightly to prevent it from falling off abnormally;

[0012] 2. Use the hook of the lifting equipment to hang on the hanging plate to improve the convenience of transporting the guide tube.

[0013] Furthermore, the guide pipe is made of a steel skeleton composite pipe.

[0014] The above-mentioned further beneficial effects are: the steel skeleton composite pipe has certain rigidity and toughness, which can improve the structural stability of the guide pipe, and its surface is smooth, which can reduce the adhesion of materials.

[0015] Furthermore, the flange is made of steel.

[0016] Furthermore, the bottom end of the flow guide tube is spaced a predetermined distance from the inner bottom end of the stirring tank.

[0017] Furthermore, the diameter of the guide tube extending out of the stirring tank is larger than the diameter of the guide tube extending into the stirring tank. BRIEF DESCRIPTION OF THE DRAWINGS
