It can be widely used in industrial sewage and municipal sewage treatment. However, this patent has the problem of not being able to effectively relieve pressure when the pressure is too high. Therefore, it is necessary to design a device for pressure relief and temperature control of the reaction tank. Summary of the invention

[0004] The object of the present invention is to provide a silicon nitride reaction tank to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a silicon nitride reaction tank, comprising a reaction tank, the inner wall of the reaction tank is provided with a stirring mechanism, the rear side of the top surface of the reaction tank is respectively fixedly connected with a liquid material port and a solid material port, the front side of the top surface of the reaction tank is provided with a pressure relief mechanism, the lower surface of the reaction tank is provided with a discharge mechanism, the right side of the liquid material port is provided with a solid material port, the front side of the solid material port is provided with a pressure relief mechanism, the end of the stirring mechanism away from the upper surface of the reaction tank is fixedly connected with the discharge mechanism, the stirring mechanism comprises a stirring rod, and the upper surface of the stirring rod is meshingly connected with a stirring rod. The rotating shaft has a connecting block fixedly connected to the outer surface of the stirring rotating shaft, and a semi-arc stirring paddle is fixedly connected to the end of the connecting block away from the stirring rod, and a cylindrical fixing column is fixedly connected to the side of the semi-arc stirring paddle away from the connecting block, and a fixing rod is hingedly connected to the right side of the cylindrical fixing column, and a fixed rod rotating shaft is hingedly connected to the rear side of the fixed rod, and a long scraper is hingedly connected to the rear side of the fixed rod rotating shaft, and a short stirring rod is fixedly connected to the stirring rod around. Before using the silicon nitride reaction tank, open the solid material port to add materials into it, and drive the stirring rod to rotate through an external motor, and the rotation of the stirring rod drives the stirring rotating shaft to rotate at the same time When the stirring shaft rotates, the connected connecting block also starts to rotate, and the connecting block then drives the semi-arc stirring paddle to rotate. The semi-arc stirring paddle stirs the surrounding materials and mixes them with other materials. At this time, all the short stirring rods on the surface of the stirring rod also rotate with the stirring rod. The short stirring rods stir the materials stirred by the semi-arc stirring paddle for a second time to make the materials more uniform. When the stirring rod rotates slowly, the fixed rod is connected through a cylindrical fixed column and rotates with the semi-arc stirring paddle to stir the materials. When the stirring rod rotates faster, the fixed rod connected to the surface of the semi-arc stirring paddle is deformed under the action of gravity and centrifugal force, and The fixed rod is allowed to rotate around the connection with the cylindrical fixed column. The fixed rod rotating shaft connected to the fixed rod drives the long scraper to rotate. The solid rod rotating shaft ensures the stirring of the long scraper. When the long scraper is attached to the inner wall of the reaction tank, it will scrape off the material attached to the inner wall of the reaction tank to prevent excessive waste of materials. It can also be further stirred three times to make the stirring more uniform. In addition, it prevents the material from solidifying on the inner wall of the reaction tank and affecting subsequent cleaning.

When the air pressure in the reaction tank is too high, the pressure increases and the bottom of the valve is pressurized. When the air pressure increases to a certain amount, the air pressure squeezes and opens the valve to deflect the cylindrical shaft connected to the pressure relief port, so that a gap is generated between the valve and the pressure relief port. When the pressure relief port is sealed, a layer of rubber pad on the surface of the valve is used to prevent When the reaction tank leaks, the gas will automatically open the valve through the pressure relief mechanism to exhaust automatically. After the pressure is relieved, the air pressure is reduced and the valve is reset under the action of the spring to reseal the pressure relief port. A spring is connected between the upper surface of the valve and the pressure relief port. When the air pressure is reduced and is not enough to push the valve, the spring will recover. At this time, the valve will close and the reaction tank will continue to react. This cycle will continue until the material reaction is completed. A large amount of water vapor will be generated when the reaction tank is running. Part of the water vapor adheres to the upper end of the inner wall of the reaction tank, and the other part of the water vapor adheres to the lower end of the valve and condenses around the shaking barrel. Water droplets. When the stirring rod rotates with the pressure rod, the pressure rod rotates with the semi-cylindrical rubber to sweep away the water droplets on the upper end of the inner wall of the reaction tank. When sweeping to the pressure relief port, the semi-cylindrical rubber recovers to its original state because of the loss of force from the upper end of the inner wall of the reaction tank. The semi-cylindrical rubber pushes the shaking barrel to move up and down to make the water droplets in the pressure relief port fall off, preventing accidents caused by excessive air pressure inside the reaction tank, preventing excessive temperature inside the reaction tank from causing material damage due to high temperature, reducing material loss, ensuring the stability of internal air pressure and temperature, preventing the problem of excessive air pressure, and facilitating rapid cooling after pressure relief.

The present invention is provided with a pressure relief port, a cylindrical rotating shaft, a rubber pad, an elastic sheet, a shaking barrel, a spring, a valve, a pressure rod, and a semi-cylindrical rubber. When the air pressure in the reaction tank is too high, the pressure increases to pressurize the bottom of the valve. When the air pressure increases to a certain amount, the air pressure squeezes and opens the valve to deflect around the connection of the pressure relief port. At this time, the gas will automatically open the valve through the pressure relief mechanism to automatically exhaust.

When the stirring rod 201 rotates slowly, the fixed rod 207 is connected through the cylindrical fixed column 209 and rotates with the semi-arc stirring paddle 204 to stir the material. When the stirring rod 201 rotates faster, the fixed rod 207 connected to the surface of the semi-arc stirring paddle 204 causes the torsion spring to deform under the action of gravity and centrifugal force, and allows the fixed rod 207 to rotate around the connection with the cylindrical fixed column 209. The fixed rod shaft 205 connected to the fixed rod 207 The rotating shaft 205 drives the long scraper 206 to rotate, and the fixed rod rotating shaft 205 ensures the stirring of the long scraper 206.

[0023] The pressure relief mechanism 5 includes a pressure relief port 501, which is fixedly connected to the front side of the top of the reaction tank 1. The inner wall of the pressure relief port 501 is hingedly connected with a cylindrical rotating shaft 502. One end of the cylindrical rotating shaft 502 away from the inner wall of the pressure relief port 501 is fixedly connected with a valve 507. The upper surface of the valve 507 is fixedly connected with a rubber pad 503.

The pressure relief port 501 is slidably connected with the shaking barrel 505. The upper end of the semi-cylindrical rubber 509 is arc-shaped. The semi-cylindrical rubber 509 contacts the shaking barrel 505. When the air pressure is weakened and is not enough to push the valve 507, the spring 506 will recover. At this time, valve 507 will be closed, and reaction tank 1 will continue to react in this cycle until the material reaction is completed. A large amount of water vapor will be generated when the reaction tank 1 is in operation. Part of the water vapor adheres to the upper end of the inner wall of the reaction tank 1, and the other part of the water vapor adheres to the lower surface of valve 507 and condenses into water droplets around the shaking barrel 505. When the stirring rod 201 rotates with the pressure rod 508, the pressure rod 508 rotates with the semi-cylindrical rubber 509 to sweep away the water droplets on the upper end of the inner wall of the reaction tank 1. When the pressure is swept to the pressure relief port 501, the semi-cylindrical rubber 509 is The force from the upper end of the inner wall of the reaction tank 1 is lost and it returns to its original state. The elastic sheet 504 is forced to shrink due to the force of the semi-cylindrical rubber 509. When the force of the semi-cylindrical rubber 509 disappears, the elastic sheet 504 is reset.

[0024] The discharging mechanism 6 includes a discharging port 601, the bottom surface of the discharging port 601 is hingedly connected to a discharging cover 602, the upper surface of the discharging cover 602 is provided with a support rod 603, the top of the support rod 603 is fixedly connected to a sweeping rod 605, the upper surface of the sweeping rod 605 is fixedly connected to a cylindrical support body 606, the middle part of the sweeping rod 605 is slidably connected to a spline rod 604, the stirring shaft 202 located at the bottom side is slidably connected to the cylindrical support body 606, the support rod 603 is fixedly connected to the cylindrical support body 606, the spline rod 604 is slidably connected to the cylindrical support body 606, the lower end of the support rod 603 is in contact with the discharging cover 602, the discharging mechanism 6 includes a discharging port 601, the bottom surface of the discharging port 601 is hingedly connected to a discharging cover 602, the upper surface of the discharging cover 602 is provided with a support rod 603, the top of the support rod 603 is fixedly connected to a sweeping rod 605, the sweeping rod A cylindrical support body 606 is fixedly connected to the upper surface of 605, and a spline rod 604 is slidably connected to the middle part of the sweeping rod 605. The stirring shaft 202 located on the bottom side is slidably connected to the cylindrical support body 606, the support rod 603 is fixedly connected to the cylindrical support body 606, the spline rod 604 is slidably connected to the cylindrical support body 606, and the lower end of the support rod 603 is in contact with the discharge cover 602. The spring 506 on the upper surface of the cylindrical support body 606 releases its elastic force and pushes the cylindrical support body 606 to fall along with the sweeping rod 605. The sweeping rod 605 falls and contacts the bottom of the reaction tank 1. The sweeping rod 605 sweeps out the material at the bottom of the reaction tank 1 as the stirring rod 201 rotates. The sweeping rod 605 helps the stirring mechanism 2 to stir when it is in place, so that the stirring is more uniform. A sealing ring is added around the discharge cover 602 to ensure that the reaction tank 1 is in a closed environment when working.

[0025] Working principle: before using the reaction tank 1, first open the solid material port 4 to add materials into it. If liquid materials need to be added, pour them in from the liquid material port 3. The stirring rod 201 is driven to rotate by an external motor. The stirring rod 201 rotates and drives the stirring shaft 202 to rotate at the same time. When the stirring shaft 202 rotates, the connected connecting block 203 also starts to rotate. The connecting block 203 then drives the semi-arc stirring paddle 204 to rotate. The semi-arc stirring paddle 204 stirs the surrounding materials and mixes them with other materials. At this time, all the short stirring rods 208 on the surface of the stirring rod 201 also rotate with the stirring rod 201. The short stirring rod 208 stirs the materials stirred by the semi-arc stirring paddle 204 for a second time to make the materials more uniform. When the stirring rod 201 rotates slowly, the fixed rod 207 is connected through the cylindrical fixed column 209 and rotates with the semi-arc stirring paddle 204 to stir the materials. When the stirring rod 201 rotates faster, the fixed rod 207 connected to the surface of the semi-arc stirring paddle 204 causes the torsion spring to be deformed under the action of gravity and centrifugal force, and the fixed rod 207 rotates around the connection point of the cylindrical fixed column 209, and the fixed rod rotating shaft 205 connected to the fixed rod 207 drives the long scraper 206 to rotate, and the solid rod rotating shaft 205 ensures the stirring of the long scraper 206. When the long scraper 206 is attached to the inner wall of the reaction tank 1, it will scrape off the material attached to the inner wall of the reaction tank 1 to prevent excessive waste of materials. It can further perform three stirrings to make the stirring more uniform. In addition, it prevents the material from solidifying on the inner wall of the reaction tank 1 and affecting subsequent cleaning. The stirring mechanism 2 stirs the material in the reaction tank 1 more uniformly, and the long scraper 206 reduces the material consumption, and the long scraper 206 can scrape off the material adhering to the surrounding of the reaction tank 1. When the air pressure in the reaction tank 1 is too high, the pressure increases and the bottom of the valve 507 is pressurized. When the air pressure increases to a certain amount, the air pressure squeezes and opens the valve 507, and the cylindrical rotating shaft 502 connected to the pressure relief port 501 deflects, so that a gap is generated between the valve 507 and the pressure relief port 501. When the pressure relief port 501 is sealed, a rubber pad 503 on the surface of the valve 507 prevents the reaction tank 1 from leaking during the reaction. At this time, the gas will automatically open the valve 507 through the pressure relief mechanism 5 for automatic exhaust. After the pressure is relieved, the air pressure is reduced and the valve 507 is reset under the action of the spring 506 to reseal the pressure relief port 501. A spring 506 is connected between the upper surface of the valve 507 and the pressure relief port 501. When the air pressure is weakened and is not enough to push the valve 507, the spring 506 will recover. At this time, the valve 507 will be closed, and the reaction tank 1 will continue to react in this cycle until the material reaction is completed. A large amount of water vapor will be generated when the reaction tank 1 is running. Part of the water vapor adheres to the inner wall of the reaction tank 1, and part of the water vapor adheres to the inner wall of the valve 507 and the shaking barrel 505 to condense into water droplets. When the stirring rod 201 rotates with the pressure rod 508, the pressure rod 508 rotates with the semi-cylindrical rubber 509 to sweep away the water droplets on the upper end of the inner wall of the reaction tank 1. When the pressure is swept to the pressure relief port 501, the semi-cylindrical rubber 509 recovers to its original state because of the loss of the force from the upper end of the inner wall of the reaction tank 1. The elastic sheet 504 is forced to shrink by the force of the semi-cylindrical rubber 509. When the force of the semi-cylindrical rubber 509 disappears, the elastic sheet 504 is reset. At this time, the shaking barrel 505 moves up and down to make the water droplets in the pressure relief port 501 fall off, preventing accidents caused by excessive air pressure in the reaction tank 1, preventing the material from being damaged due to excessive temperature in the reaction tank 1, reducing material loss, ensuring the stability of the internal air pressure and temperature, preventing the problem of excessive air pressure, and facilitating rapid cooling after pressure relief. When the machine finishes stirring, the worker opens the discharge port 601, and the discharge cover 602 connected to the discharge port 601 opens, and the support rod 603 loses the upward force of the discharge cover 602 and falls downward. Since the support rod 603 is connected to the sweeping rod 605, the sweeping rod 605 moves downward at this time, and the spring 506 on the upper surface of the cylindrical support body 606 releases the elastic force and pushes the cylindrical support body 606 to fall along with the sweeping rod 605. The sweeping rod 605 falls and contacts the bottom of the reaction tank 1. The sweeping rod 605 sweeps out the material at the bottom of the reaction tank 1 as the stirring rod 201 rotates. The sweeping rod 605 helps the stirring mechanism 2 to stir when it is in place, so that the stirring is more uniform. A sealing ring is added around the discharge cover 602 to ensure that the reaction tank 1 is in a closed environment when working.
