Description

Technical Field

[0001] This application relates to the field of mineral slurry leaching and mixing technology, and in particular to a calcium mirabilite slurry leaching and mixing device. Background Technology

[0002] Glauber's salt is an important inorganic salt chemical product, mainly used in glass manufacturing, fertilizer production, and water treatment industries. With the development of related industries' requirements for raw material quality and technological advancements, the production process and product quality of Glauber's salt are also continuously improving. In the mining and processing of Glauber's salt, leaching and stirring technology plays a crucial role. Traditional stirring structures and impeller structures are relatively simple, resulting in low leaching efficiency and extraction rate.

[0003] Meanwhile, the basic principle of the calcium glazeol slurry leaching stirred tank technology is to fully disperse and suspend the particles in the calcium glazeol slurry through stirring, thereby increasing the contact area between the particles and the leaching agent and improving the leaching efficiency and leaching rate. During the stirring process, the rotation of the stirring paddle generates shear force and eddies, causing the slurry to form a turbulent state, which is beneficial to the dispersion and suspension of particles.

[0004] Although the technology of leaching stirred tanks for calcium mirabilite slurry has made some progress and achieved certain application results, how to further improve the stirring efficiency and leaching rate is still a problem that needs to be solved by the existing staff. Utility Model Content

[0031] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0032] In order to achieve the above objectives,

[0033] Reference Figures 1-2 The embodiments of this application provide a calcium sulfonate slurry leaching and stirring device, including a stirring container 2, a stirring device 1 and a gas distribution device 3. The stirring device 1 and the gas distribution device 3 are both disposed in the stirring container 2, the gas distribution device 3 is located at the bottom of the stirring container 2, and the stirring device 1 is located above the gas distribution device 3.

[0034] A stirring container 2 is used to hold the calcium sulfate slurry; a stirring device 1 is used to thoroughly stir the calcium sulfate slurry in the stirring container 2; a gas distribution device 3 is installed at the bottom of the stirring container 2 to inject gas (such as air, oxygen, or inert gas) into the slurry. The gas distribution device 3 can be designed as a perforated plate, nozzle, or bubble diffuser to promote sufficient contact and mixing between the gas and the slurry, which helps the chemical reaction to proceed and improves the leaching efficiency.

[0035] The stirring device 1 includes a drive motor 11, a transmission shaft 12 and stirring blades 13. The drive motor 11 is mounted on the top of the stirring device 1, the transmission shaft 12 is connected to the drive motor 11, and a number of stirring blades 13 are arranged circumferentially along the transmission shaft 12.

[0036] The stirring container 2 has a cylindrical structure, and the bottom of the inner cavity of the stirring container 2 is an arc-shaped groove. The stirring blade 13 includes a fan blade part 131 and an auger part 132. The fan blade part 131 is located above the auger part 132, and the auger part 132 is rotatably connected to the bottom of the groove.

[0037] The stirring blade 13 includes a fan blade section 131 and an auger section 132 arranged sequentially from top to bottom.

[0038] The fan blades 131 of the stirring blades 13 play a primary role in stirring the sodium sulfate slurry in the stirring container 2, while the auger 132 stirs the precipitated portion of the sodium sulfate slurry, effectively pushing the sodium sulfate slurry at the bottom of the tank upwards and preventing sedimentation. The fan blades 131 and auger 132 of the stirring blades 13 ensure that the sodium sulfate slurry is uniformly and thoroughly stirred within the tank, effectively improving the leaching rate and efficiency of sodium sulfate and calcium sulfate.

[0039] Optionally, the stirring device 1 in this embodiment also includes a reducer, the load-bearing capacity of which should match the torque of the drive shaft 12. The drive motor 11 is a servo motor. The bottom of the stirring container 2 is provided with a drain hole 6, wherein the drain hole 6 is equipped with a solenoid valve for use. The drain hole 6 and the gas distribution device 3 are staggered. The bottom of the drive shaft 12 is provided with a bearing. The drain hole 6 and the bearing should be staggered. The bottom of the bearing is provided with a hollow support frame. The support frame and the gas distribution device 3 are staggered, so that the slurry in the stirring container 2 can leave the stirring container 2 through the drain hole 6. The top of the stirring container 2 is detachably provided with a splash guard 7.

[0040] Optionally, in this embodiment, the inner wall of the mixing container 2 is provided with a plurality of baffles 4 spaced circumferentially to increase liquid convection. The ratio of the baffle length to the tank height is 1:1.2~2, and the ratio of the width to the tank diameter is 1:5~15. The ratio of the distance between the baffle and the tank sidewall to the baffle width is 1:2~5 to ensure that the slurry can flow slowly and reduce local eddies, thereby further improving the mixing uniformity of the slurry.

[0041] The number of water-separating plates 4 is four, and the four water-separating plates 4 are evenly spaced on the inner side wall of the mixing container 2.

[0042] After the drive motor 11 starts, it drives the reducer, which in turn rotates the rotating shaft. The paddle structure and auger structure on the transmission shaft 12 rotate accordingly, thoroughly agitating the sodium sulfate slurry in the mixing container 2. The presence of the baffles creates localized turbulence in the slurry during agitation, preventing eddies and stratification around the agitator 1. By adjusting the design parameters of the agitator blades 13 and the baffles, efficient and uniform agitation of the slurry can be achieved, thereby improving the leaching rate and efficiency of sodium sulfate and calcium sulfate.

[0043] As an optional implementation, the gas distribution device 3 of this embodiment includes an air compressor 31, an air supply pipe 32 and an air outlet pipe 33 connected in sequence. The air outlet pipe 33 is arranged around the bottom of the stirring device 1, and the air outlet pipe 33 is provided with a plurality of air outlet holes 34 at intervals.

[0044] By designing the gas distributor, gases (such as air or oxygen) can be evenly dispersed into the slurry. Through a well-designed gas distributor, the gas can be evenly distributed throughout the entire stirring device 1 in the form of tiny bubbles, thereby increasing the gas-liquid contact area and improving the mass transfer efficiency between the gas and the slurry.

[0045] On the other hand, as bubbles rise, they cause the surrounding slurry to tumble and mix, thus achieving a stirring effect. This stirring method not only improves stirring efficiency but also ensures that solid particles and liquids in the slurry are fully mixed, which is conducive to chemical reactions or the dissolution of substances.

[0046] It should be noted that the air compressor 31 can make the gas have a certain pressure, and the diameter of the air outlet 34 is small. The slurry is generally viscous, so there will be no situation where the slurry blocks the air outlet 34 or flows into the air outlet pipe 33 through the air outlet 34.

[0047] Optionally, the gas distributor in this embodiment should be made of corrosion-resistant and wear-resistant materials to extend its service life and reduce maintenance costs. For example, corrosion-resistant materials such as stainless steel and titanium alloys can be used.

[0048] It should be noted that the gas outlet pipe 33 in this embodiment is spirally laid around the bottom of the stirring container 2. This is only a preferred embodiment. In other embodiments, the gas distributor can also be arranged around the inner wall of the stirring container 2.

[0049] As an optional implementation, this embodiment also includes a processing module. The mixing container 2 is equipped with a density detection device 5, and both the density detection device 5 and the mixing device 1 are electrically connected to the processing module.

[0050] This embodiment incorporates a density detection device 5 within the mixing container 2. This device 5 can utilize existing density sensors, allowing for real-time monitoring of slurry density changes. The density sensor can operate based on radioactivity, ultrasound, vibrating tubes, or other non-contact measurement principles to ensure accuracy and stability. The density sensor signal is transmitted to a processing module, which adjusts the rotational speed of the drive motor 11 based on preset density ranges and target values ​​within a pre-programmed sequence. When the slurry density exceeds the target value, the stirring speed is increased to promote particle dispersion and reaction; conversely, when the slurry density falls below the target value, the stirring speed is appropriately reduced to conserve energy.

[0051] The density detection device 5 includes an ultrasonic density measuring instrument. Based on the characteristic that ultrasonic waves travel at different speeds through media of different densities, the density of the medium is calculated by measuring the propagation speed of the ultrasonic waves.

[0052] This allows for non-contact measurement, suitable for measuring the density of various liquids and solids. However, the measurement accuracy is affected by factors such as the ultrasonic wave propagation path, medium temperature, and pressure.

[0053] Optionally, the processing module in this embodiment may use the AT89S51 chip. The AT89S51 is a low-power, high-performance CMOS 8-bit processor; it integrates a general-purpose 8-bit central processing unit and an ISP Flash memory unit, enabling timely and effective processing of received information. It should be noted that the processing module can be an integrated circuit chip with signal processing capabilities. This processing module can be a general-purpose processor, including a central processing unit, network processor, etc.; it can also be a digital signal processor, application-specific integrated circuit, field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. It is not limited to the AT89S51 chip in this embodiment.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.
