[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] The present utility model provides a stainless steel reactor Figures 1 to 4 as shown, which is convenient for adjusting pressure. It includes a kettle body 1, and a base 2 for support is fixedly connected to the bottom end of the kettle body 1. The kettle body 1 is made of stainless steel, and structures such as a stirring motor, stirring blades, and a discharge cylinder are provided on the kettle body 1. The reactor and its working principle are all common existing technologies and will not be elaborated here.
[0023] When the reactor is in use, the materials inside the kettle body 1 will generate certain gas, causing the internal pressure of the kettle body 1 to increase. To achieve the pressure relief effect, a valve body 3 is penetrated through the top of the kettle body 1, and the valve body 3 is fixedly connected to the kettle body 1. A pressure relief hole 16 is penetrated through the lower half of the side wall of the valve body 3, and a plurality of pressure relief holes 16 are provided. The plurality of pressure relief holes 16 are evenly distributed around the side wall of the valve body 3. A lower sliding block 9 is slidably arranged inside the valve body 3, and an upper sliding block 11 is slidably arranged inside the valve body 3. A spring 10 is fixedly connected to the lower surface of the upper sliding block 11, and the bottom end of the spring 10 is fixedly connected to the lower sliding block 9. A threaded hole is opened at the top end of the valve body 3, and a threaded rod 13 is threadedly connected inside the threaded hole. One end of the threaded rod 13 located inside the valve body 3 is fixedly connected to a pressing block 12, and the pressing block 12 is rotatably connected to the upper sliding block 11. By setting the threaded rod 13 and the pressing block 12, the upper sliding block 11 is limited.
[0024] Specifically, when the internal pressure of the kettle body 1 is relatively large, the internal pressure of the kettle body 1 will push the lower sliding block 9, and the lower sliding block 9 slides upward against the elastic force of the spring 10 until the lower sliding block 9 slides above the pressure relief hole 16, and finally the gas is discharged through the pressure relief hole 16; when the internal pressure of the kettle body 1 is restored, the spring 10 resets and pushes the lower sliding block 9, and the lower sliding block 9 slides downward to close the pressure relief hole 16, thus maintaining the internal pressure balance of the kettle body 1.
[0025] To prevent the reactants from entering the valve body 3, a filter screen 4 is fixedly connected to the bottom of the valve body 3. A round rod 5 is penetrated through the filter screen 4, and the round rod 5 is rotatably connected to the filter screen 4. The round rod 5 is concentric with the filter screen 4. A scraping strip 8 is fixedly connected to the bottom end of the round rod 5, and the scraping strip 8 is attached to the lower surface of the filter screen 4. By setting the filter screen 4, the reactants can be prevented from entering the valve body 3, and a small amount of reactants will adhere to the filter screen 4 due to the air flow; at the same time, when the round rod 5 rotates, it will drive the scraping strip 8 to rotate synchronously, and the scraping strip 8 scrapes the reactants attached to the filter screen 4 to avoid blockage of the filter screen 4.
[0026] A circular ring 6 is fixedly connected to the top end of the round rod 5, and a plurality of fan blades 7 are fixedly connected to the outer ring of the circular ring 6. The plurality of fan blades 7 are evenly distributed around the outer ring of the circular ring 6.
[0027] When the gas finally discharges through the pressure relief hole 16 from the valve body 3, it will drive the round rod 5 to rotate through the fan blades 7, thereby driving the scraping strip 8 to rotate synchronously.
[0028] By providing structures such as the filter screen 4, the round rod 5, and the scraping strip 8, it is possible to prevent reactants from entering the valve body 3, and at the same time scrape the reactants attached to the filter screen 4 to avoid clogging of the filter screen 4 and improve the efficiency of pressure regulation.
[0029] In addition, the round rod 5 can limit the lower sliding block 9. When the lower sliding block 9 abuts against the round rod 5, it cannot continue to move downward, which is convenient for adjusting the distance between the upper sliding block 11 and the lower sliding block 9; and when the lower sliding block 9 abuts against the round rod 5, it can prevent the round rod 5 and the scraping strip 8 from rotating randomly, reducing wear.
[0030] When it is necessary to adjust the balanced pressure value, rotate the threaded rod 13. When the threaded rod 13 rotates downward, the spring 10 is compressed and the pressure balance value becomes larger; when the threaded rod 13 rotates upward, the spring 10 tends to the natural length and the pressure balance value becomes smaller, which is convenient for adjusting according to needs.
[0031] For the convenience of rotating the threaded rod 13, an operation block 14 is fixedly connected to the end of the threaded rod 13 located outside the valve body 3, and anti-slip lines 15 are provided on the operation block 14.
