[0002] The broad understanding of the reactor is a stainless steel container for physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing, and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling, and low-speed mixing reaction functions required by the process. Important parameters such as temperature, pressure, mechanical control, and concentrations of reactants and products during the reaction process are strictly regulated.

[0003] After searching, the patent (application number: 202120299204.5) discloses "a reactor feeding device and reactor that is convenient for feeding". The device is equipped with a conical feed hopper, a horizontal conveyor belt, a slope conveyor belt, a baffle plate, a water pump, and a conveying pipe. It can simultaneously convey solid materials and liquid materials into the reactor body, thereby improving the applicability of the device, avoiding personnel from working at heights, and reducing safety hazards. However, the device has the following problems in actual operation:

[0004] First, the device uses a slope conveyor belt for loading, but the slope conveyor belt cannot ensure that the material fully enters the reactor, and there are problems of adhesion and spillage during the transportation process;

[0005] In addition, the device uses an impact cone feed hopper to prevent solid material accumulation from blocking the cone feed hopper. However, in actual work, some materials that are prone to agglomeration are difficult to break up by vibration due to their large size, and there is still a greater risk of blockage.

[0025] In this embodiment, the method of conveying materials by conveyor belt is replaced, and spiral forced feeding is performed by a spiral conveying auger 3. The material in the loading frame 4 can be forcibly fed into the kettle body 1 under the action of the spiral conveying auger 3, avoiding the adhesion and scattering of the material, having the characteristics of sufficient feeding, and avoiding the waste of material.

[0026] Example 2, refer to Figure 3 A feeding device for an explosion-proof spherical reactor, wherein a cylinder 6 is fixedly connected to the outer wall of one side of a feeding frame 5 by bolts, and a piston rod of the cylinder 6 is connected to a connecting plate 7, a servo motor 8 is installed on the inner wall of one end of the connecting plate 7, and a rotating rod 9 is connected to the output shaft of the servo motor 8, and a crushing blade 10 is welded to the outer wall at the bottom of the rotating rod 9, and a spiral column 11 is welded to the outer wall at the bottom of the crushing blade 10.

[0027] In this embodiment, the rotating rod 9 is pushed downward by the cylinder 6. Under the action of the servo motor 8, the crushing blade 10 and the spiral column 11 can rotate simultaneously, thereby crushing the agglomerated materials and controlling the downward flow of the materials, which effectively avoids the blockage of the materials. The process is reasonable, the operation is simple, and the practicability is strong.

[0034] Working principle: the material in the unloading frame 5 will first fall into the loading frame 4. If the unloading speed is found to be reduced during the unloading process, the rotating rod 9 can be pushed downward by the cylinder 6. Under the action of the servo motor 8, the crushing blade 10 and the spiral column 11 can rotate at the same time, thereby crushing the agglomerated material and controlling the downward flow of the material to prevent material blockage. After that, the material in the loading frame 4 can be forcibly fed into the kettle body 1 under the action of the spiral conveying auger 3 to complete the overall loading operation.
