Description

A multi-stage countercurrent leaching device for alumina production Technical Field

[0001] This utility model relates to the field of alumina production technology, specifically to a multi-stage countercurrent leaching device for alumina production. Background Technology

[0002] A multi-stage countercurrent leaching device for alumina production refers to equipment specifically designed for the efficient leaching of alumina from bauxite in the alumina production process. This device consists of multiple leaching sections connected in series. By having the leaching solution containing alkali flow in opposite directions to the bauxite in each section, the leaching reaction gradually occurs in each section under different temperature and concentration conditions, utilizing the dissolving effect of the alkali in the leaching solution on the alumina in the bauxite.

[0003] Currently, in existing technologies, the stirring device in the multi-stage countercurrent leaching device for alumina production only stirs in one direction. This one-way stirring method makes the stirring flow field relatively simple and difficult to achieve all-round and uniform stirring of materials. In view of this, we propose a multi-stage countercurrent leaching device for alumina production. Summary of the Invention

[0004] The main objective of this invention is to provide a multi-stage countercurrent leaching device for alumina production, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a multi-stage countercurrent leaching device for alumina production, comprising a tank body, a connecting pipe connected to the tank body, a valve body provided on the connecting pipe, a motor fixedly connected to the top of the tank body, and an auxiliary mechanism provided inside the tank body, the auxiliary mechanism including a fixing box, the fixing box being fixedly connected to the inner wall of the tank body.

[0006] Preferably, multiple sets of elastic telescopic rods are fixedly connected to the inner wall of the fixing box.

[0007] Preferably, the bottom of the inner wall of the fixing box is fixedly connected with multiple sets of protrusions.

[0008] Preferably, the motor is fixedly connected to the connecting plate through its output end, the connecting plate has multiple sets of grooves on its side wall, and the connecting plate is slidably connected to a movable rod.

[0009] Preferably, a circular block is fixedly connected above the movable rod, and a connecting plate is fixedly connected below the movable rod.

[0010] Preferably, a disc is fixedly connected to the middle of the movable rod, and multiple sets of protrusions are fixedly connected below the disc.

[0011] Preferably, a stirring rod is fixedly connected below the connecting plate. With the cooperation of the groove on the side wall of the connecting plate, the rotation of the connecting plate will cause the elastic telescopic rod to continuously strike the connecting plate, thereby causing the stirring rod below to vibrate and thus improving the stirring effect. At the same time, with the cooperation of the movable rod, the disc will be driven to rotate. The rotation of the disc will also drive the second protrusion to rotate, so that the second protrusion will continuously contact the first protrusion, causing the disc to move up and down reciprocally. This will drive the stirring rod below to move up and down reciprocally while rotating, thus improving the stirring effect of the stirring rod. With the setting of multiple stirring heads below the stirring rod, the material can be quickly and thoroughly mixed, and clumps and agglomerates in the material can be effectively broken up.

[0012] This invention provides a multi-stage countercurrent leaching device for alumina production. It has the following advantages:

[0013] (1) The multi-stage countercurrent leaching device for alumina production, with the cooperation of the groove on the side wall of the connecting plate, the rotation of the connecting plate will cause the elastic telescopic rod to continuously strike the connecting plate, thereby causing the stirring rod below to vibrate, thus improving the stirring effect.

[0014] (2) The multi-stage countercurrent leaching device for alumina production can quickly and fully mix materials by setting multiple sets of stirring heads below the stirring rod, and can also effectively break up lumps and agglomerates in the materials. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-3. This utility model proposes a multi-stage countercurrent leaching device for alumina production, including a tank 1, a connecting pipe 2 connected to the tank 1, a valve body 3 provided on the connecting pipe 2, a motor 4 fixedly connected to the top of the tank 1, and an auxiliary mechanism 5 provided inside the tank 1. The auxiliary mechanism 5 includes a fixing box 51, which is fixedly connected to the inner wall of the tank 1. Through the connecting pipe 2 and the valve body 3, the material in the tank 1 is transported from top to bottom to the next tank 1 for further processing, thereby realizing the multi-stage countercurrent leaching operation in alumina production.

[0024] In the embodiments of this utility model, in order to enable the auxiliary mechanism 5 to operate better, specifically, multiple sets of elastic telescopic rods 52 are fixedly connected to the inner wall of the fixed box 51, multiple sets of protrusions 54 are fixedly connected to the bottom of the inner wall of the fixed box 51, the motor 4 is fixedly connected to the connecting plate 53 through its output end, the side wall of the connecting plate 53 is provided with multiple sets of grooves, the connecting plate 53 is slidably connected to the movable rod 55, a round block 56 is fixedly connected above the movable rod 55, a connecting plate 59 is fixedly connected below the movable rod 55, a disc 57 is fixedly connected in the middle of the movable rod 55, and multiple sets of protrusions 58 are fixedly connected below the disc 57.

[0025] Furthermore, a stirring rod 6 is fixedly connected below the connecting plate 59. With the cooperation of the groove on the side wall of the connecting plate 53, the rotation of the connecting plate 53 will cause the elastic telescopic rod 52 to continuously strike the connecting plate 53, thereby causing the stirring rod 6 below to vibrate, thus improving the stirring effect. At the same time, with the cooperation of the movable rod 55, the disc 57 will be driven to rotate. The rotation of the disc 57 will also drive the second protrusion 58 to rotate, so that the second protrusion 58 will continuously contact the first protrusion 54, causing the disc 57 to move up and down reciprocally. This will drive the stirring rod 6 below to move up and down reciprocally while rotating, thus improving the stirring effect of the stirring rod 6. With the setting of multiple stirring heads below the stirring rod 6, the material can be quickly and thoroughly mixed, and lumps and agglomerates in the material can be effectively broken up.

[0026] In this invention, during use, the output of motor 4 drives the connecting disc 53 to rotate. With the cooperation of movable rod 55 and round block 56, the rotation of the connecting disc 53 drives the connecting plate 59 to rotate. The rotation of the connecting plate 59 drives the stirring rod 6, which is fixedly connected to it, to rotate, thus stirring the material in tank 1. The stirred material is then transported to the next tank 1 via connecting pipe 2 under the control of valve body 3 for further reaction. Simultaneously, with the cooperation of the groove on the side wall of the connecting disc 53, the rotation of the connecting disc 53 causes the elastic... The telescopic rod 52 continuously strikes the connecting plate 53, causing the stirring rod 6 below to vibrate, thus improving the stirring effect. At the same time, with the cooperation of the movable rod 55, it drives the disc 57 to rotate. The rotation of the disc 57 causes the second protrusion 58 to rotate as well, so that the second protrusion 58 continuously contacts the first protrusion 54, causing the disc 57 to move up and down reciprocally. This, in turn, causes the stirring rod 6 below to rotate and move up and down reciprocally, thus improving the stirring effect of the stirring rod 6.
