Description

Technical Field

[0001] The invention relates to the technical field of barium sulfate processing, and in particular to a stirring device of a reaction kettle for barium sulfate processing. Background Art

[0002] At present, chemical plants producing barium sulfate need to pass chlorine into low-purity barium sulfate slurry to obtain barium chloride slurry for subsequent production when purifying barium sulfate. As the reaction equipment for purifying barium sulfate, how to effectively ensure the uniformity of the reaction between the slurry and chlorine, thereby accelerating the reaction time and improving production efficiency, is the key to the design of the reactor. The uniform reactor for chlorination process of preparing barium sulfate with patent number CN108311086A is improved over the existing reactor with charging device. The hollow ventilated stirrer structure design is adopted, so that chlorine can be ejected from the uniformly distributed gas outlet nozzles on the stirrer. As the stirrer rotates and stirs continuously, the chlorine is fully mixed into the raw material slurry and can fully react with the raw material slurry.

[0003] Although the use of mechanical stirring and pneumatic stirring mixing methods has a good stirring effect on the raw material slurry and ensures that the chlorine gas and the raw material slurry are fully mixed, the existing reactor obtains barium chloride slurry after being filled with chlorine. During discharge, the slurry may adhere to the inner wall of the reactor or the surface of the stirring device, resulting in incomplete discharge of the reactants. Summary of the Invention

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0037] Example 1, please refer to Figures 1 to 5 A stirring device for a reactor for processing barium sulfate includes a mechanical stirring module 100 and a chlorine filling module 200.

[0038] See also Figure 4 The mechanical stirring module 100 is installed inside the barium sulfate reactor 1. The mechanical stirring module 100 includes a stirring motor 101, a stirring shaft 102 and a plurality of stirring blades 103. The stirring motor 101 is installed on the top of the barium sulfate reactor 1, and the stirring shaft 102 is rotatably installed inside the barium sulfate reactor 1. The stirring blades 103 are installed on the periphery of the stirring shaft 102. The stirring motor 101 can drive the stirring shaft 102 and the plurality of stirring blades 103 to stir the barium sulfate slurry inside the barium sulfate reactor 1 so that it is evenly mixed with the chlorine gas. This is a conventional mechanical stirring method for stirring during the chlorine-filled purification process of barium sulfate.

[0039] See also Figure 4 The mechanical stirring module 100 also includes a plurality of fixed chip pieces 104, which are fixedly installed inside the barium sulfate reactor 1 through a mounting ring and are used to block and assist in stirring the flowing barium sulfate slurry and barium chloride slurry. The barium sulfate slurry and barium chloride slurry stirred by the stirring blades 103 and the chlorine charging module 200 are blocked by the fixed chip pieces 104 and collide with them, thereby destroying the regularity of the flow of the barium sulfate slurry and the barium chloride slurry, improving the mixing effect of the barium sulfate slurry and chlorine, and at the same time accelerating the drying of the barium chloride slurry.

[0040] See also Figure 5The chlorine filling module 200 includes an air supply seat 201 and a plurality of air jet pipes 202. The air supply seat 201 is installed inside the barium sulfate reactor 1 and is located at the bottom of the barium sulfate reactor 1. The air supply seat 201 is connected to an air supply pipe 203. The air jet pipe 202 is rotatably connected to the top of the air supply seat 201. A plurality of air jet holes are provided on the top of the air supply seat 201 and the air jet pipe 202. The air supply seat 201 is equipped with an air jet opening and closing mechanism 300 for opening and closing the plurality of air jet holes. The interior of the barium sulfate reactor 1 is equipped with an air jet rotation driving mechanism 400 for driving the air jet pipe 202 to rotate. The air supply pipe 203 is connected to an external high-pressure chlorine storage tank. The external high-pressure chlorine storage tank sends high-pressure chlorine into the air supply seat 201 and the air jet pipe 202, and sprays it through the air jet holes to blow the barium sulfate slurry in the barium sulfate reactor 1, thereby using chlorine to pneumatically stir the barium sulfate slurry. At the same time, chlorine and barium sulfate slurry react to form barium chloride slurry. High-pressure chlorine cooperates with the mechanical stirring module 100 to stir the barium sulfate slurry so that the chlorine and barium sulfate slurry are fully mixed, and the mixing effect is good. When there is no ventilation, the jet opening and closing mechanism 300 is used to close the jet hole to prevent the barium sulfate slurry from entering the jet pipe 202 or the inside of the air supply seat 201 and causing blockage, thereby causing waste of resources. During ventilation, high-pressure gas is blown out from the jet hole to blow away the barium sulfate slurry near the jet hole, thereby avoiding blockage. A pressure relief valve is installed on the top of the barium sulfate reactor 1. After a certain amount of chlorine is fed into the barium sulfate reactor 1, the air pressure in the barium sulfate reactor 1 increases. The pressure relief valve can be used to relieve the pressure in the barium sulfate reactor 1 and discharge excess gas, thereby ensuring the air pressure in the barium sulfate reactor 1 is stable, while ensuring the purity of the chlorine in the barium sulfate reactor 1 and accelerating the reaction efficiency.

[0041] See also Figure 5The jet opening and closing mechanism 300 includes a jet opening and closing electric cylinder 301, multiple blocking covers 302 and multiple blocking rings 303. The jet opening and closing electric cylinder 301 is installed on the air supply seat 201. The multiple blocking covers 302 are respectively sealed and slidably matched with the multiple jet holes on the top of the air supply seat 201. The blocking rings 303 are sealed and slidably sleeved on the periphery of the corresponding jet pipe 202. The multiple blocking rings 303 on the same jet pipe 202 are connected by a synchronous frame 304, and the multiple blocking covers 302 are connected by a connecting frame 305. The synchronous frame 304 and the connecting frame 305 are connected. The connecting frame 305 is fixedly installed at the output end of the jet opening and closing electric cylinder 301. The jet opening and closing electric cylinder 301 can drive the synchronous frame 304 and the connecting frame 305 to rise and fall, thereby driving the multiple blocking covers 302 and multiple The baffle ring 303 is raised and lowered, and when the jet opening and closing electric cylinder 301 drives the baffle cover 302 and the baffle ring 303 to be at the lowest position, the baffle cover 302 is located inside the jet hole corresponding to the top of the air supply seat 201 to close the jet hole, and the baffle ring 303 is located at the jet hole height position of the jet pipe 202 to block the jet hole on the jet pipe 202, thereby preventing the barium sulfate slurry from entering the jet hole. When the jet opening and closing electric cylinder 301 drives the baffle cover 302 and the baffle ring 303 to rise, the baffle cover 302 is removed from the inside of the jet hole to release the blockage of the jet hole, and the baffle ring 303 rises to a height position away from the jet hole to release the blockage of the jet hole on the jet pipe 202, thereby allowing high-pressure chlorine to be ejected from the jet hole, stirring the barium sulfate slurry while mixing and reacting with it.

[0042] See also Figure 1 and Figure 5 The jet rotation drive mechanism 400 includes a transmission chamber 401 and a jet rotation drive motor 402. The transmission chamber 401 is installed at the top of the plurality of jet pipes 202. The jet pipe 202 and the transmission chamber 401 are in rotational cooperation. The jet rotation drive motor 402 is installed at the top of the transmission chamber 401. The plurality of jet pipes 202 are connected by a sprocket chain transmission. The corresponding jet pipe 202 is fixedly installed at the output end of the jet rotation drive motor 402. The jet rotation drive motor 402 can drive the corresponding jet pipe 202 to rotate. The synchronous rotation of the plurality of jet pipes 202 can be achieved through the transmission action of the sprocket chain, so that the plurality of jet holes on the jet pipe 202 are filled with chlorine in different directions, so that the chlorine and the barium sulfate slurry are fully mixed. At the same time, air is blown to various positions in the barium sulfate reactor 1 during discharge, so that the discharge is more thorough. The sprocket chain can be shielded by the transmission chamber 401 to prevent the barium sulfate slurry from accumulating between the sprocket chains, causing waste of resources and affecting the cooperation of the sprocket chains.

[0043] It should be noted that a drop cover 2 is installed at the top of the transmission chamber 401. The drop cover 2 is prism-shaped, and the top of the drop cover 2 is an edge of the prism. The barium sulfate slurry falls into the interior of the barium sulfate reactor 1 from the feed port. The barium sulfate slurry falling on the top of the drop cover 2 will slide along the surface of the drop cover 2, thereby avoiding the accumulation of barium sulfate slurry on the surface of the drop cover 2 and the transmission chamber 401.

[0044] Example 2, please refer to Figures 1 to 5 On the basis of Example 1, a stirring device for a reactor for processing barium sulfate further includes a drying and heating component 500, which includes a drying cylinder 501 and a hot water tank 502. The drying cylinder 501 surrounds the periphery of the barium sulfate reactor 1, and the top and bottom of the drying cylinder 501 are respectively connected to a cold water outlet pipe and a hot water inlet pipe. A heater 503 is installed inside the hot water tank 502, and the hot water tank 502 is connected to a water pump 504. The water outlet end of the water pump 504 is connected to the hot water inlet pipe, and the cold water outlet pipe and the hot water tank 502 are connected. The hot water tank 502 is filled with water, which can be heated by the heater 503. The water pump 504 pumps out the hot water and sends it into the drying drum 501 through the hot water inlet pipe. The drying drum 501 is gradually filled with hot water, thereby heating the interior of the barium sulfate reactor 1, drying the moisture in the barium chloride slurry generated by the reaction, reducing the adhesion between the barium chloride slurry and the barium sulfate reactor 1 and its internal components. The hot water flows back to the interior of the hot water tank 502 from the cold water outlet pipe for circulation, heating and utilization.

[0045] See also Figure 1 The air supply pipe 203 is connected to the gas heating pipe 3, and the gas heating pipe 3 is folded and arranged inside the hot water tank 502. The end of the gas heating pipe 3 away from the air supply pipe 203 passes through the hot water tank 502 and extends to the outside and is connected to an air inlet pipe. The air inlet pipe is connected to an external high-pressure chlorine storage tank. The external high-pressure chlorine storage tank sends high-pressure chlorine into the gas heating pipe 3. The area of ​​the gas heating pipe 3 inside the hot water tank 502 is large, so that the hot water in the hot water tank 502 can fully heat the high-pressure chlorine inside the gas heating pipe 3. The hot gas is sent into the air supply seat 201 and the injection pipe 202 through the air supply pipe 203 and sprayed into the interior of the barium sulfate reactor 1. The high-pressure chlorine heats the barium sulfate slurry while stirring the barium sulfate slurry, thereby accelerating the reaction rate of the chlorine and the barium sulfate slurry, and at the same time making the prepared barium chloride slurry have a certain temperature, which is convenient for subsequent drying.

[0046] Example 3, please refer to Figure 1 and Figure 6On the basis of Example 1 and Example 2, a stirring device for a reactor for processing barium sulfate further includes a feeding buffer chamber 4 and a discharging buffer chamber 5, which are respectively connected to the feeding port and the discharging port of the barium sulfate reactor 1. The bottom of the feeding buffer chamber 4 and the discharging buffer chamber 5 are both equipped with a discharging opening and closing mechanism 600. When feeding, the barium sulfate slurry is added to the interior of the barium sulfate reactor 1 from the feeding port, and the barium sulfate slurry first enters the interior of the feeding buffer chamber 4. The discharging opening and closing mechanism 600 closes the feeding buffer chamber 4. After the feeding is completed, the feeding port is closed, and then the feeding port is opened by the discharging opening and closing mechanism 600. The barium sulfate slurry in the feed buffer chamber 4 enters the interior of the barium sulfate reactor 1 and is fully stirred. When discharging, the discharge port is opened, and the fully reacted and dried barium chloride solid is discharged from the discharge port into the discharge buffer chamber 5. The discharge opening and closing mechanism 600 closes the discharge buffer chamber 5. After a period of time, the discharge port is closed, and the discharge buffer chamber 5 is opened by the discharge opening and closing mechanism 600 to discharge the barium chloride solid in the discharge buffer chamber 5. During the feeding and discharging process, the barium sulfate reactor 1 is prevented from being directly connected to the outside world through the feed buffer chamber 4 and the discharge buffer chamber 5, thereby preventing the dried barium chloride powder from escaping during feeding and discharging.

[0047] See also Figure 6 The discharge opening and closing mechanism 600 includes a discharge opening and closing electric cylinder 601 and an opening and closing plate 602. The discharge opening and closing electric cylinder 601 is installed on the outer wall of the feed buffer chamber 4 or the discharge buffer chamber 5. The opening and closing plate 602 is located at the bottom of the feed buffer chamber 4 or the discharge buffer chamber 5 and is used to close the feed buffer chamber 4 or the discharge buffer chamber 5. The discharge opening and closing electric cylinder 601 can drive the opening and closing plate 602 to rise and fall. The opening and closing plate 602 rises to close the bottom of the feed buffer chamber 4 or the discharge buffer chamber 5 and block the barium sulfate slurry or barium chloride solid. The opening and closing plate 602 descends to open the bottom of the feed buffer chamber 4 or the discharge buffer chamber 5, and the barium sulfate slurry or barium chloride solid can fall to complete the feeding or discharging.

[0048] It should be noted that a conical drop block 6 is installed on the top of the opening and closing plate 602. The barium sulfate powder can slide down quickly when it falls on the conical drop block 6. The bottom of the conical drop block 6 is adapted to the surface area of ​​the opening and closing plate 602, thereby preventing the barium sulfate slurry or barium chloride powder from accumulating on the opening and closing plate 602.

[0049] Vibration motors are installed outside the feed buffer chamber 4 and the discharge buffer chamber 5. The vibration motors drive the feed buffer chamber 4, the discharge buffer chamber 5, the feed port and the discharge port to vibrate, thereby facilitating the falling of the barium sulfate slurry at the feed port and the falling of the barium chloride solid at the discharge port, making the discharge more thorough.
