[0004] However, when the above-mentioned discharging valve for a stainless steel reaction kettle is in use, when the valve core moves downward and the material surges towards the discharging pipe, due to the limited discharging of the discharging pipe, some materials are likely to enter below the valve core. After long-term accumulation, it is likely to affect the downward movement of the valve core, and further affect the use of the device. Therefore, a discharging valve for a stainless steel reaction kettle is needed. Summary of the Invention

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1-4, A discharge valve for a stainless steel reactor provided by the utility model: It includes a valve body 1. A valve stem 3 is movably connected inside the valve body 1. A valve core 2 is fixedly connected to the top of the valve stem 3. A chute 10 is opened at the bottom of the valve core 2. A slide bar 11 is fixedly connected to the inner side wall of the chute 10. A spring 12 and a slider 13 are sleeved outside the slide bar 11, and the end of the spring 12 is in contact with the side end face of the slider 13. A fixing ring 14 is fixedly connected to the bottom of the slider 13. A fixing column 15 is fixedly connected inside the fixing ring 14. A first baffle 16 is rotatably connected to the outside of the fixing column 15. An activity groove 17 is opened inside the first baffle 16. A second baffle 18 is slidably connected inside the activity groove 17. A connecting shaft 22 is fixedly connected to the inner side wall of the valve body 1, and one end of the second baffle 18 away from the first baffle 16 is rotatably connected to the circumferential surface of the connecting shaft 22. A discharge rack 20 is installed on the side end face of the valve body 1. A discharge port is opened on the side end face of the valve body 1, and the discharge rack 20 corresponds to the position of the discharge port.

[0023] During use, the valve stem 3 drives the valve core 2 to move downward, so that the slider 13 squeezes the fixing column 15 through the fixing ring 14, thereby facilitating the first baffle 16 to receive the second baffle 18 into the activity groove 17. When the second baffle 18 is completely attached to the inner side wall of the activity groove 17, it generates a reverse thrust on the slider 13, and then compresses the spring 12, facilitating the inclination degrees of the first baffle 16 and the second baffle 18 to gradually decrease, enabling the material to be blocked by the first baffle 16 and the second baffle 18, preventing the material from entering below the valve core 2 and affecting the valve core 2, which is beneficial to improving the practicability of the device.

[0024] Among them, as Figure 2 shown, a connecting column 8 is fixedly connected to the bottom of the valve body 1. One end of the connecting column 8 away from the valve body 1 is fixedly connected to a base 9, and the base 9 is used to facilitate the support of the device.

[0025] Furthermore, as Figure 2 shown, the valve stem 3 is slidably connected to the inside of the base 9. A driven runner 4 is rotatably connected to the bottom of the base 9, and the valve stem 3 is threadedly connected to the inside of the driven runner 4. When the driven runner 4 rotates, it drives the valve stem 3 to move up and down, thereby realizing the up and down movement of the valve core 2.

[0026] Still further, as Figure 2 shown, a motor 5 is installed on the top of the base 9. The output end of the motor 5 penetrates the base 9 and is fixedly connected to a driving wheel 6. A transmission belt 7 is sleeved on the outer surface of the driving wheel 6, and the other end of the transmission belt 7 is sleeved on the outside of the driven runner 4.

[0027] Even further, as Figure 2As shown, the inner bottom of the valve body 1 is provided with a mounting groove, the interior of which is fixedly connected with a sealing ring 21, and the valve stem 3 is slidably connected to the interior of the sealing ring 21. The sealing ring 21 is used to enhance the sealing performance of the connection between the valve body 1 and the valve stem 3.

[0028] In addition, if Figure 4 As shown, a scraper 19 is fixedly connected to the end of the first baffle 16 away from the fixed column 15, and the scraper 19 is in contact with the outer surface of the second baffle 18. When the valve core 2 moves downward, the first baffle 16 uses the scraper 19 to scrape the material remaining on the outer surface of the second baffle 18. When the valve core 2 moves upward, the spring 12 pushes the slider 13 to move, facilitating the removal of the second baffle 18 from the interior of the first baffle 16. This increases the inclination of the first and second baffles 16, facilitates the falling of materials, and improves the convenience of material unloading.

[0029] Working principle: When the stainless steel reactor is unloaded, the valve stem 3 drives the valve core 2 to move downward, so that the slider 13 squeezes the fixed column 15 through the fixed ring 14, so that the first baffle 16 can retract the second baffle 18 into the movable groove 17. When the second baffle 18 is completely fitted with the inner wall of the movable groove 17, a reverse thrust is generated on the slider 13, which in turn compresses the spring 12, making it easier for the inclination of the first baffle 16 and the second baffle 18 to gradually decrease, so that the material is blocked by the first baffle 16 and the second baffle 18 and enters the discharge rack 20 through the discharge port, avoiding the material from entering. When the valve core 2 is in the downward movement, the first baffle 16 uses the scraper 19 to scrape the material remaining on the outer surface of the second baffle 18, and when the valve core 2 moves up, the spring 12 pushes the slider 13 to move the second baffle 18 out of the first baffle 16, so that the inclination of the first baffle 16 and the second baffle 18 is increased, which facilitates the falling of the material and is beneficial to improving the convenience of material discharge. When the valve core 2 is completely in contact with the top of the valve body 1, the top of the valve body 1 is sealed.
