Description

Technical Field

[0001] This utility model relates to the fields of hydrometallurgy and inorganic fine chemical technology, and in particular to a high gravity rotating packed bed. Background Technology

[0002] In acidic solutions with high-speed rail backgrounds, aluminum impurities are difficult to remove effectively at low pH. Metasilicates can construct a Si–O network in the acidic window, and with appropriate additives, Al co-precipitation can be induced, which is expected to achieve aluminum removal at low pH.

[0003] In the preparation of composite metasilicate powder, it is necessary to fully mix its precursor sol. Traditional equipment for preparing precursor sol is mostly a stirred tank, which uses a motor to drive the stirring rod to stir different sols and mix them together.

[0004] When mixing sols, the stirring rod is prone to creating dead zones, resulting in uneven mixing of the sol in certain areas. This leads to concentration gradients in the reactants, causing the generated sol particles to be of varying sizes. Consequently, a uniform precursor sol cannot be obtained, which affects the quality of the dried powder produced later. Utility Model Content

[0005] The purpose of this invention is to provide a high-gravity rotating packed bed that can solve the problem that the stirring rod easily creates a stirring dead zone when mixing sol, resulting in uneven mixing of the sol in some areas. This leads to a concentration gradient of reactants, causing the generated sol particles to be of different sizes, making it impossible to obtain a uniform precursor sol, and affecting the quality of the dried powder produced subsequently.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-gravity rotating packing bed, comprising a support box, a liquid injection mechanism, and a mixing mechanism. The liquid injection mechanism is located outside the support box and includes a fixed cylinder, an electric push rod, and a rubber stopper. Two sets of fixed cylinders are fixedly installed on the outer wall of the support box. An electric push rod is fixedly installed at the bottom of the fixed cylinder. The free end of the electric push rod extends into the interior of the fixed cylinder and is fixedly installed with a rubber stopper. The outer wall of the rubber stopper is in contact with but not connected to the inner wall of the fixed cylinder. The mixing mechanism is located inside the support box and includes a rotating rod and a rotating frame. The bottom inner side of the support box is rotatably connected to one end of the rotating rod, and the other end of the rotating rod is fixedly connected to the bottom of the rotating frame.

[0007] Preferably, the injection mechanism further includes an internally threaded tube, a threaded sealing cap, a graduated glass window, an outlet tube, and a nozzle. The outer wall of the fixed cylinder has a strip-shaped opening, and a graduated glass window is embedded inside the strip-shaped opening. The top of the fixed cylinder is fixedly connected to one end of the internally threaded tube and is in communication with it. A threaded sealing cap is threadedly installed on the inner wall of the internally threaded tube. An outlet tube is fixedly installed on the top of the fixed cylinder. One end of the outlet tube extends into the interior of the support box and is fixedly installed with a nozzle. It can quantitatively add sodium silicate solution and aluminum sulfate solution according to the required amount of sol and simultaneously spray them into the porous corrugated packing, so that the solutions collide and contact each other.

[0008] Preferably, the mixing mechanism further includes a motor and porous corrugated packing. The motor is fixedly installed at the bottom of the support box, and the output shaft of the motor is fixedly connected to one end of the rotating rod. The inner wall of the rotating frame is provided with porous corrugated packing, which is located below the nozzle. The high-speed porous corrugated packing causes the material to form intense turbulence in the packing area, achieving millisecond-level residence mixing, avoiding concentration gradients in the reactants, ensuring uniform particle size of the generated sol, ensuring a homogeneous precursor solution, and guaranteeing the quality of the subsequently produced dry powder.

[0009] Preferably, the outlet pipe is equipped with a one-way valve facing into the support box.

[0010] Preferably, a cover is snapped onto the top of the support box, and a handle is fixedly installed on the top of the cover.

[0011] Preferably, a discharge pipe is fixedly installed at the bottom of the support box, and one end of the discharge pipe is connected to the inside of the support box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The high gravity rotating packing bed, through the combined use of a fixed cylinder, an internal threaded pipe, a threaded sealing cap, an electric push rod, a rubber stopper, a graduated glass window, a liquid outlet pipe and a nozzle, can quantitatively add sodium silicate solution and aluminum sulfate solution according to the required amount of sol and spray them into the porous corrugated packing at the same time, so that the solutions can collide and contact each other.

[0013] (2) The high gravity rotating packed bed, through the combined use of motor, rotating rod, rotating frame and porous corrugated packing, the material is made to form violent turbulence in the packing area by the high speed of porous corrugated packing, realizing millisecond-level residence and mixing, avoiding the concentration gradient of reactants, making the generated sol particles uniform in size, ensuring that a uniform precursor solution is obtained, and ensuring the quality of the dried powder produced later.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a high-gravity rotating packing bed, including a support box 1, a liquid injection mechanism 3, and a mixing mechanism 4. The liquid injection mechanism 3 is disposed outside the support box 1 and includes a fixed cylinder 301, an electric push rod 304, and a rubber stopper 305. Two sets of fixed cylinders 301 are fixedly installed on the outer wall of the support box 1. An electric push rod 304 is fixedly installed at the bottom of the fixed cylinder 301. The free end of the electric push rod 304 extends into the interior of the fixed cylinder 301 and is fixedly installed with a rubber stopper 305. The outer wall of the rubber stopper 305 is flush with the fixed cylinder 301. The inner walls are fitted but not connected; the mixing mechanism 4 is located inside the support box 1, and the mixing mechanism 4 includes a rotating rod 402 and a rotating frame 403. The bottom inner side of the support box 1 is rotatably connected to one end of the rotating rod 402, and the other end of the rotating rod 402 is fixedly connected to the bottom of the rotating frame 403; a one-way valve facing into the support box 1 is provided on the liquid outlet pipe 307; a box cover 2 is snapped onto the top of the support box 1, and a handle 6 is fixedly installed on the top of the box cover 2; a discharge pipe 5 is fixedly installed at the bottom of the support box 1, and one end of the discharge pipe 5 is connected to the inside of the support box 1.

[0018] Secondly, the injection mechanism 3 also includes an internally threaded tube 302, a threaded sealing cap 303, a graduated glass window 306, an outlet tube 307, and a nozzle 308. The outer wall of the fixed cylinder 301 has a strip-shaped opening, and the graduated glass window 306 is embedded inside the strip-shaped opening. The top of the fixed cylinder 301 is fixedly connected to one end of the internally threaded tube 302 and they are in communication. The inner wall of the internally threaded tube 302 is threadedly fitted with a threaded sealing cap 303. The top of the fixed cylinder 301 is fixedly fitted with an outlet tube 307. One end of the outlet tube 307 extends into the interior of the support box 1 and is fixedly fitted with a nozzle 308. It can quantitatively add sodium silicate solution and aluminum sulfate solution according to the required amount of sol and simultaneously spray them into the porous corrugated packing 404, so that the solutions collide and contact each other.

[0019] Furthermore, the mixing mechanism 4 also includes a motor 401 and a porous corrugated packing 404. The motor 401 is fixedly installed at the bottom of the support box 1. The output shaft of the motor 401 is fixedly connected to one end of the rotating rod 402. The inner wall of the rotating frame 403 is provided with porous corrugated packing 404. The porous corrugated packing 404 is located below the nozzle 308. The high-speed porous corrugated packing 404 causes the material to form violent turbulence in the packing area, achieving millisecond-level residence mixing, avoiding concentration gradients of reactants, ensuring uniform particle size of the generated sol, ensuring a uniform precursor solution, and guaranteeing the quality of the subsequently produced dry powder.

[0020] Working principle: When using this device, the electric push rod 304 is activated to extend and retract, causing the rubber stopper 305 to move within the fixed cylinder 301. The position of the rubber stopper 305 on the graduated glass window 306 is adjusted according to the ratio of sodium silicate solution to aluminum sulfate solution. Then, the sodium silicate solution and aluminum sulfate solution are added to the two sets of fixed cylinders 301 respectively through the internally threaded tube 302. The threaded sealing cap 303 is screwed into the internally threaded tube 302 to seal the fixed cylinders 301. The electric push rod 304 is then extended, causing the rubber stopper 305 to squeeze the solution within the fixed cylinder 301, which is then discharged through the outlet pipe 301. 7. The solution in the fixed cylinder 301 is squeezed out and sprayed into the porous corrugated packing 404 through two sets of nozzles 308. At the same time, the motor 401 is turned on to drive the rotating rod 402 to rotate, which in turn drives the rotating frame 403 to rotate, thereby driving the porous corrugated packing 404 to rotate at high speed. Under the action of high shear and turbulence, the two fluids are rapidly dispersed and reacted in the porous corrugated packing 404 to generate a uniformly sized aluminosilicate sol, which passes through the porous corrugated packing 404 and is thrown into the support box 1. It is discharged and collected through the discharge pipe 5. The box cover 2 can be removed through the handle 6 to clean or repair the inside of the support box 1.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
