During the use of existing dust, saltpeter and sulfur production reactors, the materials usually contain particles or dense powders, which are easy to accumulate or clog on the screen. The screen cannot be shaken, and it is difficult for the material to fall. In addition, some liquids need to be evenly dispersed or mixed. After a part of the screen is blocked, the liquids that fall are easy to gather in one place, resulting in poor reaction effect. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0020] Embodiment: A dust, saltpeter and sulphur integrated reactor, such as Figure 1-Figure 4As shown, it includes a reactor shell 1, a feed valve 2, a discharge valve 21, a motor 3, a transmission rod 4, a bracket 5, a screen 7, a bump 8 and a contact frame 9. The reactor shell 1 is sleeved on the bracket 5. The feed valve 2 is arranged on the top of the reactor shell 1, and the discharge valve 21 is arranged on the bottom of the reactor shell 1. The motor 3 is installed on the top of the reactor shell 1. The transmission rod 4 is rotatably connected in the reactor shell 1. The top of the transmission rod 4 is fixedly connected to the output shaft of the motor 3. The screen 7 is slidably connected to the transmission rod 4. The bottom of the screen 7 is provided with a bump 8, which is hemispherical. A contact frame 9 is fixed inside, and the contact frame 9 is slidably connected to the protrusion 8. The top of the contact frame 9 is rounded and will not get stuck when contacting the protrusion 8. A limit block is fixed on the inner wall of the reactor shell 1, located at the bottom around the screen 7, for limiting the screen 7 from sliding down, and the screen 7 is a double-layer design, connected by a round tube in the middle, and a raised stripe is provided in the middle of the transmission rod 4, which does not affect the rotation of the screen 7 but can also make the screen 7 rotate. A stirring rod is fixed to the bottom of the transmission rod 4, which can stir the material and accelerate the reaction. A moving handle is also installed on the reactor shell 1 for hoisting and moving the reactor shell 1.

[0021] like Figure 3 As shown, a conical block 6 is also included. The conical block 6 is arranged on the top of the transmission rod 4, and the conical block 6 is slidably connected to the transmission rod 4.

[0022] The motor 3 is turned on, and then the raw materials are added through the feed valve 2. The motor 3 drives the screen 7 to rotate through the transmission rod 4. When the bottom protrusion 8 contacts the contact frame 9, the screen 7 will slide up and down as a whole. Since the middle part of the transmission rod 4 is provided with raised stripes, the screen 7 can also slide when the screen 7 is driven to rotate. Therefore, when the raw materials fall, they are broken up by the rotating screen 7, and the screen 7 shakes up and down, and the raw materials will not remain on the screen 7. Moreover, the conical block 6 on the top of the screen 7 will make the raw materials slide around and will not be pushed near the transmission rod 4, thereby ensuring that all the raw materials can be dispersed and fall. The stirring rod at the bottom of the transmission rod 4 can accelerate the reaction. Moreover, when the liquid raw material falls, the conical block 6 and the screen 7 can also disperse the position where the liquid falls, so that the reaction is faster and more complete, and the mixing effect is optimized. After the reaction is complete, the motor 3 is turned off, the discharge valve 21 is opened, and all the reactants are discharged.

[0023] like Figure 1 and Figure 5As shown, it also includes a pressure controller 10, a U-shaped guide rod 11, a rack 12, an air guide tube 13, a piston rod 14, a spring 15 and a gear 16. The pressure controller 10 is installed at the outer end of the reactor shell 1, the U-shaped guide rod 11 is fixedly connected to the outer end of the reactor shell 1, the air guide tube 13 is fixedly connected to the top of the reactor shell 1, the bottom of the rack 12 is slidably connected to the U-shaped guide rod 11, the top of the rack 12 is fixedly connected to the piston rod 14, the piston rod 14 is slidably connected in the air guide tube 13, a gear 16 is installed on the knob of the pressure controller 10, the gear 16 is meshed with the rack 12, a spring 15 is sleeved on the piston rod 14, one end of the spring 15 is fixedly connected to the top of the piston rod 14, and the other end is fixedly connected to the bottom of the air guide tube 13.

[0024] During the reaction of the raw materials, a large amount of gas will be generated, thereby increasing the pressure inside the reactor shell 1. The increased pressure can accelerate the reaction between the raw materials, but excessive pressure will damage the reactor shell 1 and even cause danger. Existing reactors are equipped with pressure relief valves, but the pressure relief valve can only keep the pressure inside the reactor within a safe range and cannot adjust the degree of pressure relief according to the reaction stage of the raw materials. Therefore, the gas can now push the piston rod 14 to move through the air guide pipe 13, and the pressure is indirectly measured through the spring 15, and through the movement of the rack 12, It drives the gear 16 to rotate, and then according to the pressure set by the pressure controller 10, when the pressure in the reactor is smaller than the set pressure, the rack 12 drives the gear 16 to rotate without affecting the operation of the pressure controller 10. When the pressure in the reactor is larger than the set pressure, the rack 12 drives the gear 16 to rotate the rotary knob, and the pressure in the reactor is relieved through the pressure controller 10. At the end of the reaction, the pressure controller 10 can discharge the gas in the reactor shell 1. The set air pressure is a standard atmospheric pressure, so that when the discharge valve 21 is opened, the reactants will not be sprayed out due to excessive internal air pressure.
