Detailed Implementation

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] This utility model proposes a saponification negative pressure reactor, including a reactor body 1, a shell 2 fixedly installed on the inner wall of the reactor body 1, an annular pipe 3 fixedly installed on the lower wall of the reactor body 1, an air inlet pipe 4 fixedly connected to the annular pipe 3, and one end of the air inlet pipe 4 penetrating the lower wall of the reactor body 1.

[0022] The annular pipe 4 is connected to the external steam pipe. Under the action of the inlet pipe 4, the external steam can enter between the shell 2 and the side wall of the vessel 1 to heat the side wall of the shell 2.

[0023] An exhaust pipe 5, which communicates with the shell 2, is fixedly installed inside the side wall of the vessel body 1. A first one-way valve 6 is provided on the exhaust pipe 5.

[0024] The vent pipe 5 facilitates the discharge of air between the shell 2 and the side wall of the vessel 1 to the outside, while the first one-way valve 6 prevents outside air from entering the space between the shell 2 and the side wall of the vessel 1 through the vent pipe 5.

[0025] An exhaust fan 7 is fixedly installed on the outer wall of the vessel body 1. The air inlet end of the exhaust fan 7 is connected to an air inlet pipe 8. The end of the air inlet pipe 8 away from the exhaust fan 7 passes through the upper wall of the vessel body 1.

[0026] A second check valve 9 is installed on the air inlet pipe 8;

[0027] Under the action of the air inlet pipe 8, the exhaust fan 7 can draw the air in the vessel body 1, making the space inside it a negative pressure state. At the same time, the second one-way valve 9 can prevent the air drawn out by the exhaust fan 7 from flowing back into the vessel body 1 and affecting the negative pressure state.

[0028] Specifically, the upper wall of the vessel body 1 is provided with a feed pipe 10, and one end of the feed pipe 10 is provided with a sealing cap 11;

[0029] The feed pipe 10 allows workers to easily add the raw materials to be saponified into the reactor body 1. The sealing cover 11 can seal one end of the feed pipe 10 to prevent outside air from entering the reactor body 1 through the feed pipe 10. At this time, the side wall of the shell 2, which has been heated by steam, can heat the raw materials to saponify them. A temperature sensor is fixedly installed on the outer surface of the shell 2. The temperature sensor is electrically connected to the external control panel and can detect the temperature of the raw materials.

[0030] A discharge pipe 12 is fixedly installed on the lower end face of the shell 2, and one end of the discharge pipe 12 penetrates the lower wall of the vessel body 1;

[0031] A discharge port communicating with the discharge pipe 12 is formed in the lower wall of the housing 2, and a valve 13 is provided on the discharge pipe 12;

[0032] When valve 13 is open, the saponified raw material can be easily discharged through the discharge pipe 12; when closed, the discharge pipe 12 can be sealed.

[0033] Specifically, the vessel body 1 is equipped with a stirring shaft 14. The top end of the stirring shaft 14 rotates through the upper wall of the vessel body 1. A bracket is fixedly installed on the upper wall of the vessel body 1. A motor is fixedly installed on the bracket. The output end of the motor is fixedly connected to the top end of the stirring shaft 14.

[0034] A stirring blade 15 is fixedly installed inside the vessel body 1 and on the outer surface of the stirring shaft 14;

[0035] The rotation of the motor output end can drive the stirring shaft 14 to rotate. At this time, the rotation of the stirring shaft 14 can drive the stirring blade 15 to stir the raw materials and improve the saponification effect.

[0036] Specifically, a heat-conducting block 16 is fixedly installed inside the side wall of the housing 2;

[0037] The heat-conducting block 15 can absorb the heat of the steam and direct the absorbed heat to the raw materials, thereby improving the heating effect on the raw materials.

[0038] Specifically, a connecting pipe 17 is fixedly connected to the annular pipe 3, and a third one-way valve 18 is provided on the connecting pipe 17.

[0039] The connecting pipe 17 can be connected to an external steam pipe, allowing steam to be delivered into the annular pipe 3. At the same time, the third one-way valve 18 can prevent the steam in the annular pipe 3 from flowing back. Meanwhile, the lower wall of the vessel body 1 is fixedly connected to a water outlet pipe, which can discharge the water generated by the steam. A sealing cap is provided on the water outlet pipe to seal one end of the water outlet pipe.

[0040] Working principle: First, the raw materials to be saponified are added to the vessel body 1 through the feed pipe 10, ensuring the raw materials are located inside the shell 2. At this time, the operator seals one end of the feed pipe 10 with the sealing cap 11 to prevent outside air from entering the vessel body 1. Then, the external steam pipe is connected to the connecting pipe 17 to ensure continuity, and steam is transported to the annular pipe 3. The steam in the annular pipe 3 is then transported through the air inlet pipe 4 to the space between the side wall of the vessel body 1 and the shell 2, heating the side wall of the shell 2 and the heat-conducting block 16. Simultaneously, under the action of the first one-way valve 6 of the air outlet pipe 5, the gas between the side wall of the vessel body 1 and the shell 2 can be discharged to the outside, allowing steam to fill the space between the side wall of the vessel body 1 and the shell 2, improving the heating effect on the side wall of the shell 2 and the heat-conducting block 16. At this point, the process is complete. The rotation of the motor output can drive the stirring shaft 14 to rotate. At this time, the rotation of the stirring shaft 14 can drive the stirring blade 15 to stir the raw material, so that the raw material can contact the side wall of the shell 2 and the heat-conducting block 16, which can improve the heating effect. After stirring is completed, the exhaust fan 7 is started. Under the action of the air inlet pipe 8, the exhaust fan 7 can draw the air in the vessel 1, making the space inside it a negative pressure state. At the same time, the negative pressure state inside the vessel 1 can make the air bubbles in the raw material disappear. Meanwhile, the second one-way valve 9 can prevent the air drawn out by the exhaust fan 7 from flowing back into the vessel 1, affecting the negative pressure state and improving the negative pressure effect. After saponification is completed, the valve 13 is opened, which can discharge the saponified raw material in the shell 2 from the storage tank 12 for easy collection and convenience.
