[0002] Phosphorus pentasulfide is an inorganic compound with the chemical formula P2S5. It is a yellow solid and stable when dry. However, it hydrolyzes into phosphoric acid and hydrogen sulfide when in contact with water, so there is a smell of rotten eggs in the air. The production of phosphorus pentasulfide requires first melting sulfur and yellow phosphorus into liquid, and then mixing them in a reactor to undergo a chemical reaction to generate phosphorus pentasulfide. Since the corresponding stirred reactor is required in the production reaction process.
[0003] The stirring rods used in the stirred reactors of the phosphorus pentasulfide reaction devices in the prior art are mostly fixedly arranged. If the stirring range of the stirring rod is to be fully achieved, a large-sized stirring rod must be used, which easily affects the storage volume inside the reactor, thereby affecting the phosphorus sulfide content processed in a single production, and is not conducive to use.
[0004] Therefore, a reaction device for producing phosphorus pentasulfide is needed to solve the problem that the stirred reactor of the phosphorus sulfide reaction device in the prior art needs to use a large-sized stirring rod to ensure that the stirring range of the stirring rod is sufficient, which easily affects the storage volume inside the reactor.

DETAILED DESCRIPTION
[0020] See also Figure 1-5 The utility model provides a reaction device for producing phosphorus pentasulfide, comprising a reaction barrel 1, an opening 14 is provided at the middle position of the top of the reaction barrel 1, a stirring rod 2 is inserted into the opening 14, a motor 3 is fixed to one end of the top surface of the reaction barrel 1, a support seat 5 is fixed to the position of the top of the reaction barrel 1 near the motor 3, a connecting rod 4 is fixed to the output end of the motor 3, the connecting rod 4 and the support seat 5 are rotatably connected, a movable shaft 6 is passed through the surface of the support seat 5 for rotatable connection, a rotating disk 7 is fixed to the top of the movable shaft 6, a moving frame 8 is provided on the top of the rotating disk 7, a conflicting shaft 15 is inserted into the inner cavity of the moving frame 8, the bottom of the conflicting shaft 15 is fixed to the surface of the rotating disk 7, and symmetrically distributed conflicting shafts are fixed to the surfaces of both sides of the moving frame 8 Rod 9, the outer circumference of the stirring rod 2 is fixedly sleeved with a ring 16, one side of the interference rod 9 passes through the reaction barrel 1 and extends to a position close to the ring 16, and the outer circumference of the ring 16 is provided with an annular groove 17, and plug blocks 18 are slidably inserted on both sides of the inner cavity of the annular groove 17. The surfaces of the plug blocks 18 on the side away from each other are fixed to the surfaces of the interference rod 9 at the adjacent position. When the motor 3 is started, the rotating disk 7 can be rotated, so that the moving frame 8 drives the two interference rods 9 to reciprocate in the horizontal direction, so that the stirring rod 2 can reciprocate in the horizontal direction during the rotational movement, so that the stirring rod 2 can ensure that the stirring rod 2 has a large stirring range without using a large-sized stirring rod 2, thereby reducing the impact on the volume of the reaction barrel 1.
[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the outer peripheral surface of the connecting rod 4 is fixedly sleeved with a first bevel gear 10, and the outer peripheral surface of the movable shaft 6 is fixedly sleeved with a second bevel gear 11, and the first bevel gear 10 and the second bevel gear 11 are meshingly connected. When the motor 3 is started, the connecting rod 4 is rotated, so that the first bevel gear 10 can be rotated, so that the movable shaft 6 can be rotated under the meshing action between the first bevel gear 10 and the second bevel gear 11.
[0022] Further as Figure 4 As shown, it is worth specifically explaining that a circular gear 13 is fixedly sleeved on the outer circumferential surface of the stirring rod 2 at a position located outside the reaction barrel 1, and a rack 12 is meshed with one end of the circular gear 13, and the bottom of the rack 12 is fixed to the surface of the top of the reaction barrel 1. When the stirring rod 2 reciprocates in the horizontal direction under the action of the resistance rod 9, the stirring rod 2 can reciprocate in the horizontal direction and rotate at the same time under the meshing action between the circular gear 13 and the rack 12.
[0023] Further as Figure 2 As shown, it is worth explaining in detail that a vertical plate 19 is fixed at one end of the moving frame 8 on the top surface of the reaction barrel 1, and a limit strip 21 is fixed on the surface of the vertical plate 19. An interference groove 20 is provided at one end of the moving frame 8 close to the limit strip 21, and one end of the limit strip 21 extends to the inner cavity position of the interference groove 20 and fits with the inner cavity surface of the interference groove 20. When the moving frame 8 reciprocates in the horizontal direction, the inner cavity surface of the interference groove 20 will interfere with the limit strip 21 to limit the movement trajectory of the moving frame 8, thereby further limiting the movement trajectory of the moving frame 8, so that the moving frame 8 can move more smoothly in the horizontal direction.
[0024] This solution has the following working process: in actual use, when sulfur and yellow phosphorus liquid solvents are added to the interior of the reaction barrel 1 and the outlet pipe of the reaction barrel 1 is sealed, the motor 3 is then started to rotate the connecting rod 4, so that the first bevel gear 10 can rotate, so that the movable shaft 6 can rotate under the meshing action between the first bevel gear 10 and the second bevel gear 11, so that the rotating disk 7 can rotate, so that the interference shaft 15 can make a circular motion, so that the interference shaft 15 can conflict with the inner cavity surface of the moving frame 8, because the inner cavity surface of the interference groove 20 will have a conflict and limit effect with the limit strip 21, so as to further limit the movement trajectory of the moving frame 8, so that the moving frame 8 can be in the interference shaft 1 5, so that the resistance rod 9 can reciprocate in the horizontal direction, so that the stirring rod 2 can reciprocate in the horizontal direction under the resistance of the plug block 18 and the ring 16. When the stirring rod 2 reciprocates in the horizontal direction, the circular gear 13 can rotate under the meshing action of the rack 12. When the stirring rod 2 rotates, due to the connection setting of the annular groove 17 and the plug block 18, the stirring rod 2 can reciprocate in the horizontal direction and rotate at the same time, so as to expand the stirring range of the stirring rod 2, so that the stirring rod 2 can have a large stirring range without using a large-sized stirring rod 2, thereby reducing the impact on the volume of the reaction barrel 1, thereby improving the applicability of the device.
[0025] According to the above working process, it can be known that: by starting the motor 3, the rotating disk 7 can rotate, so that the moving frame 8 drives the two resistance rods 9 to reciprocate in the horizontal direction, so that the stirring rod 2 can reciprocate in the horizontal direction during the rotational movement, so that the stirring rod 2 can have a large stirring range without using a large-sized stirring rod 2, thereby reducing the impact on the volume of the reaction barrel 1, thereby improving the applicability of the device, thereby improving the practicality of the device.
[0026] Further as Figure 3 As shown, it is worth explaining in detail that the two ends of the inner cavity surface of the moving frame 8 are arranged in an arc shape, and the outer peripheral surface of the resistance shaft 15 is in contact with the inner cavity surface of the moving frame 8. Due to the shape setting of the inner cavity surface of the moving frame 8 and the connection setting of the resistance shaft 15, when the resistance shaft 15 moves to the two ends of the inner cavity of the moving frame 8, it will not get stuck, which is beneficial to the stability of the moving frame 8 when it reciprocates.
[0027] In summary: by starting the motor 3, the rotating disk 7 can rotate, so that the moving frame 8 drives the two resistance rods 9 to reciprocate in the horizontal direction, so that the stirring rod 2 can reciprocate in the horizontal direction during the rotational movement, so that the stirring rod 2 can have a large stirring range without using a large-sized stirring rod 2, thereby reducing the impact on the volume of the reaction barrel 1, thereby improving the applicability of the device, thereby improving the practicality of the device, and due to the shape setting of the inner cavity surface of the moving frame 8 and the connection setting of the resistance shaft 15, the resistance shaft 15 can move to the two ends of the inner cavity of the moving frame 8 without getting stuck, which is beneficial to the stability of the moving frame 8 when it reciprocates.
[0028] The motor 3 can be purchased on the market. The motor 3 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
