Description

Technical Field

[0001] This utility model relates to the field of organosilicon production technology, and in particular to a device for leaching organosilicon slag. Background Technology

[0002] Organosilicon slag is a byproduct generated during the synthesis and refining of organosilicon monomers. It mainly originates from the hydrolysis and cracking processes following the reaction of industrial silicon with chloromethane. Its components include siloxane polymers, unreacted silicon powder, copper powder, and trace metal impurities (such as iron and aluminum). Organosilicon slag leaching equipment is a specialized device for treating waste residue or hydrolysis residue generated during organosilicon production. It is mainly used to recover valuable components (such as copper or high-boiling-point substances) through chemical leaching and to achieve the harmless treatment of waste residue.

[0003] Existing organosilicon slag leaching devices process organosilicon slag by mixing different batches of organosilicon slag, followed by sequential pressurization, centrifugation, gas-liquid separation, and pressure filtration to obtain a liquid rich in high-boiling substances and solid residue. The solid residue is then subjected to hydrolysis. Typically, stirring is used to mix the organosilicon slag. However, traditional stirring methods are simplistic, mostly relying on paddles for stirring, which easily leads to sedimentation at the bottom and has low stirring efficiency, affecting the overall processing efficiency. Therefore, a new organosilicon slag leaching device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing organosilicon slag leaching devices. These devices typically involve mixing different batches of organosilicon slag, followed by sequential pressurization, centrifugation, gas-liquid separation, and filtration to obtain a liquid rich in high-boiling-point substances and solid residues. The solid residues are then subjected to hydrolysis. Traditional mixing methods, often relying solely on paddles, suffer from drawbacks such as sedimentation at the bottom and low mixing efficiency, thus affecting overall processing efficiency. Therefore, this invention proposes a new organosilicon slag leaching device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for leaching organosilicon slag includes a reaction tank. A top cover is movably connected to the upper part of the reaction tank. An inlet is fixedly connected to the upper part of the top cover. A rotating shaft is rotatably connected inside the top cover. Two bevel gears (first type) are fixedly connected to the outer side of the rotating shaft. Two bevel gears (third type) are rotatably connected to the outer side of the rotating shaft. Two turntables (first type) are rotatably connected to the outer side of the rotating shaft. Two turntables (second type) are fixedly connected to the outer side of the rotating shaft. A scraper is fixedly connected to the bottom of the rotating shaft. A stirring shaft housing (first type) is rotatably connected to the upper part of each of the two turntables (first type). A stirring shaft housing (second type) is rotatably connected to the upper part of each of the two turntables (second type). Two stirring tubes are symmetrically rotatably connected inside the stirring shaft housing (first type). A bevel gear (second type) is fixedly connected to the end face of each stirring tube.

[0006] The above technical solution further includes: A servo motor is fixedly connected to the upper part of the top cover. The output end of the servo motor is fixedly connected to the rotating shaft, and the servo motor can drive the rotating shaft to rotate.

[0007] A ventilation pipe is fixedly connected to the side of the top cover, and a gas filter is fixedly connected to the side of the ventilation pipe. A sedimentation tank is fixedly connected to the bottom of the reaction tank. During the solution reaction, the exhaust gas enters the gas filter through the ventilation pipe, and after the solution reaction is completed, it enters the sedimentation tank.

[0008] A rotating tube is fixedly connected to the side of the bevel gear three. The rotating tube is rotatably connected to the rotating shaft and fixedly connected to the turntable one. The rotation of the bevel gear three can drive the turntable one to rotate.

[0009] The first bevel gear meshes with two second bevel gears simultaneously, and the two second bevel gears mesh with a third bevel gear. The rotation of the rotating shaft can drive the first bevel gear to rotate, the first bevel gear can drive the two second bevel gears to rotate simultaneously, the rotation of the two second bevel gears can drive the two stirring tubes to rotate to stir the solution, and the two second bevel gears can drive the third bevel gear to rotate simultaneously.

[0010] The bottom of the top cover is fixedly connected to the first stirring shaft housing, the first turntable is rotatably connected to the second stirring shaft housing, and the second turntable is rotatably connected to the second stirring shaft housing. The rotation of the first turntable and the second turntable keeps the second stirring shaft housing stationary.

[0011] The scraper is in contact with the inner wall of the reaction vessel.

[0012] The blades of turntable one and turntable two are in opposite directions, and the rotation directions of turntable one and turntable two are opposite. Bevel gear one drives bevel gear two to rotate, and bevel gear two drives bevel gear three to rotate, forming a coaxial reversing mechanism, so that turntable one and turntable two rotate in opposite directions.

[0013] This utility model has the following beneficial effects: In this invention, bevel gear one drives bevel gear two to rotate, and bevel gear two drives bevel gear three to rotate, forming a coaxial reversing mechanism. This causes turntable one and turntable two to rotate in opposite directions, causing the materials inside the reaction solution to tumble and stir. Bevel gear one simultaneously drives two bevel gear two to rotate, so that two stirring tubes simultaneously stir the solution, ensuring that the solution and solid are thoroughly mixed and improving the mixing efficiency of the solution.

[0014] In this invention, the rotation of the rotating shaft drives the inclined scraper to rotate and scrape the inner wall and bottom of the reaction vessel, thereby removing the solid particles that have settled at the bottom of the reaction vessel and adhered to the inner wall of the reaction vessel. This prevents solid particles from settling at the bottom of the reaction vessel and from adhering to the inner wall of the reaction vessel, thus improving the leaching efficiency of organosilicon.
