[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The present application embodiment discloses a discharge device for a reaction kettle. Figure 1-4 A discharge device for a reactor comprises a reactor body 1, a cylinder 5 and a discharge pipe 9. A feeding pipe 2 is arranged above the reactor body 1, a guide pipe 3 is arranged on one side of the feeding pipe 2, a storage box 4 is arranged below the guide pipe 3, and the storage box 4 is located above the reactor body 1. The cylinder 5 is arranged above the storage box 4. An output of one side of the cylinder 5 is provided with a gas rod 6. A sealing tube 7 is arranged on the surface of the gas rod 6. One end of the gas rod 6 is located inside the storage box 4 and is fixedly connected with a pressing plate 8. The pressing plate 8 slides along the inner wall of the storage box 4. One end of the guide pipe 3 penetrates the pressing plate 8 and is connected with the storage box 4. The discharge pipe 9 is arranged below the storage box 4. The lower part of the discharge pipe 9 is connected with the reactor body 1. A hinge seat 91 is arranged below the discharge pipe 9. A baffle 92 is arranged on one side of the hinge seat 91. The upper part of the baffle 92 fits with the lower part of the discharge pipe 9.

[0024] When the worker needs to add materials to the reactor body 1, the worker connects the raw material source through the feed pipe 2 and the guide pipe 3, and the worker inputs the raw materials into the interior of the storage box 4 through the guide pipe 3. One end of the guide pipe 3 is inserted into the pressing plate 8 to input the raw materials. The raw materials will be accumulated at the bottom of the interior of the storage box 4. When the raw materials in the storage box 4 are accumulated to a specified amount, the worker starts the cylinder 5, and the cylinder 5 will push the pressing plate 8 to slide downward along the inner wall of the storage box 4. The space below the storage box 4 is reduced, and the raw materials in the storage box 4 will be injected into the interior of the reactor body 1 through the discharge pipe 9. When the raw materials in the storage box 4 are emptied, the baffle 92 will rotate along the hinge seat 91 to seal the outlet end of the discharge pipe 9 to avoid the entry of liquid into the reactor body 1 as much as possible;

[0025] During the extension and retraction process of the gas rod 6, the surface of the gas rod 6 is protected by a sealing tube 7. The two ends of the sealing tube 7 are fixedly connected to the inner wall of the storage box 4 and the top of the pressure plate 8 respectively. The sealing tube 7 is made of rubber and has a certain ductility, which reduces the contact between the external liquid and the gas rod 6 and increases the safety of the gas rod 6 during use.

[0026] Among them, the inner wall of the storage box 4 is fixedly connected to a limiting rod 41, the limiting rod 41 is symmetrically arranged inside the storage box 4, the pressure plate 8 slides along the outer wall of the limiting rod 41, and the limiting rod 41 is vertically fixed inside the storage box 4. The pressure plate 8 can increase stability through the guidance of the limiting rod 41 during the sliding process, and sealing gaskets are arranged at the connection between the pressure plate 8 and the storage box 4 around to increase the air tightness of the storage box 4 and the pressure plate 8.

[0027] Preferably, a discharge hole 31 is provided on the output end surface of the guide tube 3, a guide groove 81 is provided inside the pressing plate 8, one end of the guide tube 3 passes through the guide groove 81 and is attached to a sealing plate 84, a telescopic rod 83 is provided above the sealing plate 84, and the telescopic rod 83 is fixed below the pressing plate 8;

[0028] The guide groove 81 allows the outlet end of the material guide tube 3 to be inserted into the interior of the pressing plate 8, making it convenient for the material guide tube 3 to inject the raw materials into the bottom of the pressing plate 8. When the pressing plate 8 rises, one end of the material guide tube 3 will fit with the sealing plate 84, and the sealing plate 84 is fixed by the upper telescopic rod 83. The raw materials will be discharged through the discharge holes 31 around the material guide tube 3, and the raw materials will enter the bottom of the pressing plate 8 along the sealing plate 84. When the pressing plate 8 descends, the internal spring of the telescopic rod 83 will pull the sealing plate 84 to slide upward until the top of the sealing plate 84 fits with the bottom of the pressing plate 8, thereby increasing the airtightness of the pressing plate 8.

[0029] Specifically, a sealing ring 82 is provided inside the pressing plate 8, and there are multiple sealing rings 82. The multiple sealing rings 82 are located inside the guide groove 81 and fit with the outer wall of the guide tube 3. When the guide tube 3 passes through the guide groove 81, the outer wall of the guide tube 3 will fit with the pressing plate 8. The sealing ring 82 inside the pressing plate 8 reduces the distance between the pressing plate 8 and the guide tube 3. The sealing ring 82 is used to seal the gap between the pressing plate 8 and the guide tube 3, thereby increasing the air tightness and reducing the backflow of raw materials in the guide tube 3 during the discharge process.

[0030] More specifically, a groove 94 is provided inside the discharge pipe 9, and a pull rod 95 is hinged above the baffle 92. One end of the pull rod 95 is located inside the groove 94 and is hinged to the inner wall of the discharge pipe 9. The groove 94 is inclined on both sides below. When the discharge pipe 9 discharges material, the downward pressure of the raw material will push the pull rod 95 open, so that the baffle 92 is away from the discharge port of the discharge pipe 9, and the raw material flows out through the gap between the discharge pipe 9 and the baffle 92. When the downward pressure of the raw material decreases, the spring inside the pull rod 95 will shrink, and the pull rod 95 will pull the baffle 92 to fit the discharge pipe 9. The internal air pressure of the reactor body 1 will also increase the pressure between the baffle 92 and the discharge pipe 9, reducing the reflux of the liquid inside the reactor body 1. The inclined opening of the groove 94 facilitates the increase of the rotation angle of the pull rod 95 when the baffle 92 is opened, thereby increasing the opening and closing angle of the baffle 92.

[0031] Furthermore, during the implementation process, a limiting groove 96 is provided at the outlet end of the discharge pipe 9, and a plug 93 is fixedly connected to the top of the baffle 92. The top of the plug 93 is located inside the limiting groove 96 and fits with the discharge pipe 9. When the bottom of the discharge pipe 9 fits with the baffle 92, the plug 93 above the baffle 92 will be embedded in the limiting groove 96 and fit tightly with the inner wall of the discharge pipe 9, thereby increasing the sealing performance of the baffle 92 and the discharge pipe 9.

[0032] The implementation principle of a discharge device of a reactor in an embodiment of the present application is as follows: when a worker needs to add materials to the reactor body 1, the worker connects with the source of raw materials through the feed pipe 2 and the guide pipe 3, and the worker inputs the raw materials into the interior of the storage box 4 through the guide pipe 3. One end of the guide pipe 3 is inserted into the pressure plate 8 to input the raw materials, and the raw materials will accumulate at the bottom of the interior of the storage box 4. When the raw materials inside the storage box 4 accumulate to a specified amount, the worker starts the cylinder 5, and the cylinder 5 will push the pressure plate 8 to slide downward along the inner wall of the storage box 4. The space below the storage box 4 is reduced, and the raw materials inside the storage box 4 will be injected into the interior of the reactor body 1 through the discharge pipe 9. When the raw materials inside the storage box 4 are emptied, the baffle 92 will rotate along the hinge seat 91 to seal the outlet end of the discharge pipe 9 to minimize the entry of liquid into the reactor body 1.
