Description

Technical Field

[0001] The present invention relates to the technical field of chemical equipment, in particular to synthesis equipment for preparing bismuth hydroxide. Background Art

[0002] A process for producing bismuth hydroxide by reacting bismuth oxide, fatty acid and sodium hydroxide is as follows:

[0003] Step 1: Bismuth oxide reacts with fatty acids at 60-100°C to produce bismuth (III) carboxylate and water.

[0004] Step 2: At 15-20°C, bismuth (III) carboxylate reacts with sodium hydroxide to generate bismuth hydroxide and carbon dioxide, which are then washed with process water and adjusted to pH 7-8.

[0005] Step 3: Let it stand and separate into layers, forming a water layer and a material layer. The material layer sinks to the bottom and the water layer is discharged.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 3 , a synthesis device for preparing bismuth hydroxide, comprising a tank body 1, a turntable 2, a cylinder body 3, a tube group 4 and a water tank 5;

[0034] Among them, the upper part of the tank body 1 is open, and the upper part of the inner circumference of the tank body 1 is fixedly connected with a mounting ring 101, and the upper end of the mounting ring 101 is coaxially rotatably mounted with a mounting disk 6, and a sealing structure is formed between the mounting ring 101 and the mounting disk 6 to meet the sealing requirements during the reaction process; a circle of teeth is formed on the outer circumferential surface of the mounting disk 6, and a gear 2 61 is provided on the side of the mounting disk 6, and the gear 2 61 is meshed with the teeth. A drive shaft 62 is coaxially fixedly connected to the gear 2 61, and the drive shaft 62 passes through and rotatably connects to the support plate 63, and the support plate 63 is fixed to the outer circumferential surface of the tank body 1; the drive shaft 62 can be driven to rotate by an external motor, so that the mounting disk 6 can rotate around the central axis of the tank body 1; further, a groove is provided at the top of the tank body 1 to cooperate with the gear 2 61 for the movement of the gear 2 61, and the groove is not connected to the inner cavity of the tank body 1;

[0035] The turntable 2 passes through and rotates to connect the mounting plate 6, and the turntable 2 and the mounting plate 6 are eccentrically arranged; the upper end of the turntable 2 is exposed from the tank body 1, and the lower end of the turntable 2 is fixedly connected to a gear 1 21, and the gear 1 21 is internally meshed with a gear ring 22, and the gear ring 22 is coaxially fixed to the lower end of the mounting ring 101; when the mounting plate 6 rotates, the turntable 2 and the gear 1 21 are driven to rotate around the central axis of the tank body 1, and the gear 1 21 is meshed with the gear ring 22 during the rotation process, so that the turntable 2 can rotate around the central axis of the tank body 1 and around its own central axis; further, the intersection point of the central axis of the turntable 2 and the central axis of the mounting plate 6 is located below the mounting plate 6, so that when the central axis of the turntable 2 rotates around the central axis of the tank body 1, a conical area with a larger bottom and a smaller top can be formed in the inner cavity of the tank body 1; further, a sealing structure is formed between the turntable 2 and the mounting plate 6 to meet the sealing requirements during the reaction process;

[0036] The lower end of the cylinder 3 is open, and the cylinder 3 is rotatably sleeved on the outer circumferential surface of the turntable 2 located above the mounting plate 6 through the lower end opening. A stabilizing plate 7 is fixedly sleeved on the outer circumferential surface of the cylinder 3. The stabilizing plate 7 is fixedly connected to the mounting plate 6 so that the cylinder 3 can rotate synchronously with the turntable 2 around the central axis of the tank body 1, and the cylinder 3 and the turntable 2 can rotate relative to each other.

[0037] The cylinder 3 has a first cavity 31 and a second cavity 32 spaced apart from each other in the upper and lower parts.

[0038] The tube group 4 includes a liquid inlet pipe 41, a liquid outlet pipe 42 and a coil 43;

[0039] One end of the liquid inlet pipe 41 extends from the bottom of the turntable 2 along the central axis of the turntable 2 through the gear 1 21 and the turntable 2 and extends to the first cavity 31. The other end of the liquid inlet pipe 41 is connected to one end of the coil 43.

[0041] The water tank 5 includes a housing 51 and a partition frame 52. The housing 51 is annular, and its inner circumference is open. The partition frame 52 is coaxially mounted between the upper and lower inner walls of the housing 51. The partition frame 52 divides the inner cavity of the housing 51 into two upper and lower, non-communicating first and second water chambers 511 and 512. The housing 51 is coaxially fixed to the upper end of the tank body 1 and contacts the upper surface of the mounting plate 6. The partition frame 52 surrounds the stabilizing plate 7.

[0042] A third pipe connector and a fourth pipe connector, which are respectively connected to the first water chamber 511 and the second water chamber 512, are fixedly connected to the inner circumference of the partition frame 52; the third pipe connector is connected to the first pipe connector through a first hose 8, and the fourth pipe connector is connected to the second pipe connector through a second hose 9; a first connecting pipe 513 and a second connecting pipe 514, which are respectively connected to the first water chamber 511 and the second water chamber 512, are fixedly connected to the outer circumference of the box body 51.

[0043] The first connecting pipe 513, the first water chamber 511, the first hose 8, the first cavity 31, the liquid inlet pipe 41, the coil 43, the liquid outlet pipe 42, the second cavity 32, the second hose 9, the second water chamber 512 and the second connecting pipe 514 together form a flow channel that flows from the first connecting pipe 513 to the second connecting pipe 514.

[0044] Multiple guide tubes 102 are fixedly connected to the outer circumference of the tank body 1, and a discharge tube 103 is fixedly connected to the bottom end of the tank body 1. Bismuth oxide, fatty acid, and sodium bicarbonate used to react to form bismuth hydroxide are fed into the tank body 1 through their respective guide tubes 102 according to the reaction sequence. The specific process is as follows:

[0045] In the first stage, bismuth oxide reacts with fatty acids to produce bismuth (III) carboxylate and water;

[0046] In the second stage, bismuth (III) carboxylate reacts with sodium bicarbonate to produce bismuth hydroxide and carbon dioxide.

[0047] In the first stage, a heat medium such as high-temperature water or high-temperature steam is introduced into the tube group 4 to maintain the temperature in the tank 1 between 60°C and 100°C. The tube group 4 is rotated and self-rotated to achieve a stirring effect. The reaction is kept warm for 2 hours.

[0048] In the second stage, the temperature of the heat medium in the tube group 4 is lowered, the temperature in the tank body 1 is adjusted between 15° C. and 20° C., and the tube group 4 is rotated and self-rotated to achieve a stirring effect.

[0049] It should be noted that, in the second stage, process water needs to be fed into the tank body 1 through the corresponding material guide pipe 102 for cleaning, and the pH value needs to be adjusted to between 7 and 8 by sodium bicarbonate.

[0050] After the reaction is completed, stirring is stopped and the mixture is allowed to stand for stratification to form a water layer and a material layer. The water layer is discharged from the tank body 1 through the corresponding material guide pipe 102. Thereafter, the material layer is vacuum dehydrated, and the vacuum dehydration temperature does not exceed 85°C and the vacuum is -0.095Mpa, so that water vapor is discharged from the tank body 1 through the corresponding material guide pipe 102. After dehydration, the temperature in the tank body 1 is adjusted to between 20°C and 25°C to obtain the finished bismuth hydroxide, and the finished bismuth hydroxide is discharged from the tank body 1 through the discharge pipe 103.

[0051] It should be noted that the carbon dioxide generated by the reaction is discharged from the tank body 1 when the water layer is discharged and the vacuum is drawn.

[0052] As a further illustration of the above technical solution, the total volume of the material in the tank body 1 will change significantly before and after vacuum dehydration, that is, only the finished bismuth hydroxide remains after vacuum dehydration, and the volume of the finished bismuth hydroxide is significantly smaller than the volume of the mixture of bismuth hydroxide and water. In addition, during vacuum dehydration, stirring and heating are required to improve the dehydration efficiency and dehydration effect. Therefore, during vacuum dehydration, in order to allow most of the coil 43 with heating and stirring functions to participate in heating and stirring the bismuth hydroxide to further improve the dehydration efficiency and dehydration effect, the tube group 4 is further configured as follows:

[0053] like Figure 4 and Figure 5As shown, the liquid inlet pipe 41 is slidably connected to the turntable 2, the gear 1 21, and the cylinder 3, and the liquid outlet pipe 42 is fixedly connected to the turntable 2. The other end of the liquid inlet pipe 41 and the other end of the liquid outlet pipe 42 are both bent at 90 degrees.

[0054] The coil 43 includes a first pipe section 431, a second pipe section 432, a third pipe section 433 and a fourth pipe section 434;

[0055] The first pipe section 431, the second pipe section 432, the third pipe section 433, and the fourth pipe section 434 are all U-shaped pipes, so that the coil 43 is elliptical, so that the coil 43 can achieve a stirring effect during the process of rotating around the central axis of the tank body 1 and the central axis of the turntable 2.

[0056] One end of the first pipe segment 431 is coaxially connected to the other end of the liquid inlet pipe 41 for rotation, and one end of the fourth pipe segment 434 is coaxially connected to the other end of the liquid outlet pipe 42 for rotation; multiple second pipe segments 432 and third pipe segments 433 are provided, and there is one more second pipe segment 432 than the third pipe segment 433. Multiple second pipe segments 432 and multiple third pipe segments 433 are alternately distributed and rotatably connected in sequence, and together constitute a retractable spiral pipe, and the angle between the connected second pipe segments 432 and third pipe segments 433 is between 40° and 100°, so that the spiral pipe has an effect similar to a "spiral sheet" lifting material during the process of rotating around the central axis of the turntable 2.

[0057] The other end of the first pipe segment 431 is coaxially connected to the second pipe segment 432 at the head end of the spiral pipe, and the other end of the fourth pipe segment 434 is coaxially connected to the second pipe segment 432 at the tail end of the spiral pipe, so that the entire coil 43 can be extended and retracted and can be extended and retracted as the liquid inlet pipe 41 slides, thereby realizing adjustment of the length of the coil 43, so that the height of the coil 43 for heating and stirring materials can be adjusted according to the height of the materials, thereby realizing effective and efficient utilization of the heating capacity and stirring capacity, thereby achieving energy saving.

[0058] Furthermore, the invention also includes an X-shaped telescopic frame formed by connecting multiple X-shaped frames 44 in sequence, which is installed on the spiral pipe and is used to extend and retract the spiral pipe. The X-shaped telescopic frame can rotate with the coil 43 to play a stirring role.

[0059] like Figure 5 As shown, the present invention provides an example of an installation combination of an X-shaped telescopic frame and a coil 43. In this example, the X-shaped frame 44 is formed by a rod 1 441 and a rod 2 442 that are crossed and rotatably connected, and multiple rods 2 442 are respectively rotatably mounted on both ends of multiple second pipe sections 432.

[0060] As the liquid inlet pipe 41 moves toward the bottom of the tank body 1, it drives the first pipe section 431 to move and rotate relative to the second pipe section 432 connected to it. After the liquid inlet pipe 41 moves to contact the X-shaped telescopic frame, it pushes the X-shaped telescopic frame to contract, thereby driving the entire coil 43 to contract; after the coil 43 contracts, the liquid inlet pipe 41 moves in the opposite direction, which can extend the coil 43.

[0061] Furthermore, the first cavity 31 passes through the top of the cylinder 3, and a piston 10 is slidably installed in the first cavity 31. The piston 10 is rotatably connected to the liquid inlet pipe 41, and a push rod 14 is slidably installed on the end of the piston 10 away from the liquid inlet pipe 41;

[0062] The top of the box body 51 is fixedly connected to a lifting device 11, and the output end of the lifting device 11 is fixedly connected to a lifting ring 12. The lifting ring 12 is coaxially distributed with the tank body 1. A lifting rod 13 is installed on the inside of the lifting ring 12. The lifting rod 13 can rotate along the circumference of the lifting ring 12. The lifting rod 13 passes through and is slidably connected to the push rod 14, so that the push rod 14 can move up and down relative to the tank body 1 and can rotate around the central axis of the tank body 1.

[0063] The lifting ring 12 and the lifting rod 13 are driven up and down by the lifting device 11 , so that the push rod 14 moves and drives the piston 10 to slide up and down in the first cavity 31 , thereby realizing the movement of the liquid inlet pipe 41 relative to the bottom of the tank body 1 .

[0064] During the sliding of the piston 10, the push rod 14 slides horizontally relative to the piston 10 and the lifting rod 13; during the rotation of the cylinder 3 around the central axis of the tank body 1, the lifting rod 13 is driven to rotate around the central axis of the tank body 1 through the piston 10 and the push rod 14.

[0065] It should be noted that the lifting device 11 is a power device capable of outputting linear motion in the prior art, such as an electric push rod, a hydraulic cylinder, a linear motor module, etc.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
