Description

Technical Field

[0001] This utility model relates to the field of leaching tank technology, specifically a leaching tank for heating mineral slurry. Background Technology

[0002] A leaching tank, also known as a liquid-solid reactor, is a liquid-solid reactor that performs leaching operations at atmospheric pressure and temperatures below 373K. It is widely used in non-ferrous metal extraction and metallurgy. For example, utility model patent CN215668142U discloses a leaching tank for heating mineral slurry, including a stirring mechanism for actively stirring the slurry. The stirring mechanism includes a drive mechanism, a rotating seat, a stirring component, and a lifting component. At least one stirring component is provided and mounted on the rotating seat. The drive component drives the rotating seat to rotate, causing the stirring component to rotate around the rotating seat. The lifting component drives the rotating seat to rise and fall, thus causing the stirring component to rise and fall with the rotating seat. At least one heating component is provided and mounted on the inner wall of the tank. This structural design allows the stirring component to rotate around the rotating seat while rotating itself, improving the material stirring effect to a certain extent. Simultaneously, the lifting mechanism drives the rotating seat and stirring component to reciprocate, further improving the uniformity of contact between the slurry and the heating component, ensuring uniform heating of the slurry, guaranteeing leaching quality and efficiency, and demonstrating strong practicality.

[0003] In current technologies, although stirring components are used to accelerate the heating efficiency of the slurry, these components are typically located in the center, resulting in slower heating of the slurry around the stirring components. Furthermore, after the slurry is discharged from the leaching tank, it tends to accumulate on the tank walls, solidifying and becoming difficult to clean. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a leaching tank for heating mineral slurry, which solves the problem in the existing technology that although the heating efficiency of mineral slurry is accelerated by the stirring component, the stirring component is generally set in the center and the heating efficiency of mineral slurry around the stirring component is still relatively slow. At the same time, it solves the problem that after the mineral slurry is discharged from the leaching tank, the tank wall is prone to slurry accumulation and solidification, which is difficult to clean.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leaching tank for heating mineral slurry, comprising a leaching tank body, a plurality of supports fixedly connected to the top of the leaching tank body, and a support base fixedly connected to the plurality of supports, an electric motor fixedly mounted on the upper end of the support base, the output shaft of the electric motor passing through the support base and connected to the support base via a bearing, a rotating shaft fixedly connected to the output shaft, a stirring frame fixedly connected to the lower section of the rotating shaft, a non-standard gear fixedly connected to the middle section of the rotating shaft, a cleaning component provided on the non-standard gear, a fixing plate fixedly connected to the inner wall of the leaching tank body, a secondary shaft mounted on the bottom of the fixing plate via a bearing, a stirring rod fixedly connected to the lower section of the secondary shaft, and a driven gear fixedly connected to the upper section of the secondary shaft, the driven gear meshing with the non-standard gear.

[0006] Preferably, an electric heating coil is provided at the bottom inner side of the leaching tank body. The electric heating coil can provide basic heating for the material.

[0007] Preferably, a drain pipe is fixedly connected to the bottom of the leaching tank body, and a valve is installed on the drain pipe. The drain pipe facilitates the subsequent discharge of material from the leaching tank body.

[0008] Preferably, the cleaning assembly includes multiple nozzles fixedly connected to the bottom of the non-standard gear. A retaining ring is rotatably connected to the top of the non-standard gear, and a conveying pipe is fixedly connected inside the retaining ring. One end of the conveying pipe is inserted into the non-standard gear, and the other end of the conveying pipe passes through the support base and extends above the support base. This cleaning assembly facilitates subsequent cleaning of the leaching tank body.

[0009] Preferably, a fixing rod is fixedly connected to the upper end of the retaining ring, and the top of the fixing rod is fixedly connected to the support base. The position of the fixing rod is symmetrical with respect to the conveying pipe. The fixing rod provides a fixing function for the retaining ring.

[0010] Preferably, the non-standard gear has an annular cavity and an annular groove inside, the annular cavity and the annular groove are connected, and the end of the conveying pipe is located in the annular groove. The annular cavity and annular groove facilitate the delivery of clean water to the rotating non-standard gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model features a rotating shaft driven by an electric motor mounted above the main body of the leaching tank. The shaft is equipped with a stirring frame and non-standard gears, which can stir the center of the slurry and accelerate its heating rate. In addition, a secondary shaft with a driven gear is installed on the inner wall of the main body of the leaching tank. The secondary shaft has a stirring rod on it, and the driven gear meshes with the non-standard gear. As the rotating shaft rotates, the secondary shaft can rotate synchronously through the transmission of the gears, thus stirring the outer periphery of the slurry as well, improving the uniformity of the slurry heating.

[0013] 2. This utility model sets a cleaning component on a non-standard gear. The non-standard gear has an annular cavity and an annular groove inside. Then, a conveying pipe with a retaining ring is set on the inner side of the annular groove. The other end of the conveying pipe can be connected to an external high-pressure water source through a pipeline. In this way, while the non-standard gear rotates with the rotating shaft, it can rinse the inner wall of the leaching tank body to prevent the slurry from solidifying on the tank wall.

[0021] Please see Figure 1-3 An electric heating coil 13 is installed at the bottom inner side of the leaching tank body 1. The electric heating coil 13 provides basic heating for the material. A drain pipe 14 is fixedly connected to the bottom of the leaching tank body 1, and a valve is installed on the drain pipe 14. The drain pipe 14 facilitates the discharge of material from the leaching tank body 1 in the later stages.

[0022] Please see Figure 3-4 The non-standard gear 7 is equipped with a cleaning assembly 8. This assembly facilitates subsequent cleaning of the leaching tank body 1. The cleaning assembly 8 includes multiple spray pipes 81 fixedly connected to the bottom of the non-standard gear 7. A retaining ring 82 is rotatably connected to the top of the non-standard gear 7. A conveying pipe 83 is fixedly connected inside the retaining ring 82. One end of the conveying pipe 83 enters the non-standard gear 7, and the other end passes through the support base 3 and extends above it.

[0023] The specific implementation process of this utility model is as follows: When in use, the electric heating coil 13 can heat the slurry in the leaching tank body 1 after being powered on. At the same time, the motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the stirring frame 6 to stir the center of the slurry, accelerating its heating speed. Meanwhile, through the cooperation of the non-standard gear 7 and the driven gear 12, the secondary shaft 10 can be driven to rotate, thereby stirring the outer periphery of the slurry through the stirring rod 11 on the secondary shaft 10, improving the uniformity of the slurry heating. After the slurry is discharged through the drain pipe 14, the conveying pipe 83 is connected to the external high-pressure water source. In this way, while the non-standard gear 7 follows the rotating shaft 5 to rotate, it can also rinse the inner wall of the leaching tank body 1 through the spray pipe 81 to prevent the slurry from solidifying on the tank wall.
