[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, a stainless steel reactor for synthesizing organic chemical raw materials comprises a shell 1, and a stirring assembly 2 for stirring the raw materials inside is provided on the upper end of the shell 1;

[0025] A feed pipe 101 is provided on the surface of the housing 1, and a discharge pipe 102 is provided at the lower end of the housing 1. Electronic valves are provided in both the feed pipe 101 and the discharge pipe 102.

[0026] Two support frames 3 are fixedly mounted on the surface of the housing 1 , support plates 4 are fixedly mounted on the lower surfaces of the two support frames 3 , and a dredging component 5 for dredging materials blocked at the discharge pipe 102 is provided between the two support plates 4 .

[0027] The stirring assembly 2 includes a first motor 201 , which is fixedly mounted on the upper end of the housing 1 . The output shaft of the first motor 201 passes through the housing 1 and is fixedly mounted with a rotating rod 202 . The rotating rod 202 is fixedly mounted with a plurality of stirring blades 203 .

[0028] The dredging component 5 includes two slide grooves 501, and the two slide grooves 501 are respectively opened on the opposite side surfaces of the two support frames 3. Slide blocks 502 are slidingly set in the two slide grooves 501. A positioning frame 503 is fixedly installed on the opposite side of the two sliders 502. A cylinder 504 is fixedly installed on the lower surface of the positioning frame 503. The output end of the cylinder 504 passes through the positioning frame 503 and is fixedly installed with a lifting plate 505. A rotating shaft 506 is rotatably installed in the middle of the upper surface of the lifting plate 505, and a dredging cone 507 is fixedly installed on the upper end of the rotating shaft 506.

[0029] The staff pours the raw materials into the interior of the outer shell 1 through the feed pipe 101, and then the staff starts the first motor 201 so that its output shaft drives the rotating rod 202 to rotate, and the rotating rotating rod 202 drives the stirring blade 203 to rotate, so that the stirring blade 203 can stir the material in the outer shell 1 and accelerate its mixing. After the mixing is completed, the staff opens the sealing valve inside the discharge pipe 102, so that the discharge pipe 102 discharges the material inside the outer shell 1. When the discharge pipe 102 is blocked, the staff controls the positioning frame 503 to move so that it moves along the direction of the slide 501 to the bottom of the discharge pipe 102. Then the staff controls the cylinder 504 so that its output end drives the dredging cone 507 to rise, so that the dredging cone 507 contacts the blocked material and dredges the blocked material, thereby completing the dredging of the discharge pipe 102 and avoiding the situation where the internal pressure of the reactor increases and causes a safety accident.

[0030] In another embodiment of the present invention, a screw rod 6 is rotatably installed between the two sides of the inner wall of one of the slide grooves 501, a slider 502 close to the screw rod 6 is threadedly arranged on one side of the rod body of the screw rod 6, and a second motor 7 is fixedly installed on one side of the support plate 4 close to the screw rod 6, and the output shaft end of the second motor 7 passes through the corresponding support plate 4 and is fixedly connected to the output shaft end of the screw rod 6.

[0031] The staff starts the second motor 7 so that its output shaft drives the screw 6 to rotate. The rotating screw 6 drives the slider 502 and the positioning frame 503 to move by screwing in the thread. The moving positioning frame 503 drives the dredging cone 507 to move to the bottom of the discharge pipe 102.

[0032] In another embodiment of the present invention, a plurality of crushing teeth 8 are fixedly mounted on the surface of the dredging cone 507 .

[0033] Through the action of the crushing teeth 8, the material is refined into smaller particles, and the gaps between these particles are enlarged, thereby improving the fluidity of the material, making it easier for it to pass through the discharge pipe, and further reducing the risk of blockage.

[0034] In another embodiment of the present invention, the shaft 506 is sleeved with a first pulley 9;

[0035] A horizontal plate 10 is fixedly mounted on one side of the lifting plate 505, and a rotating column 11 is rotatably mounted on one side of the upper surface of the horizontal plate 10. The rotating column 11 is sleeved with a second pulley 12, and a transmission belt 13 is sleeved on the surface of the first pulley 9 and the second pulley 12.

[0036] A third motor 15 is fixedly mounted on the lower surface of the transverse plate 10 . An output shaft end of the third motor 15 passes through the transverse plate 10 and is fixedly connected to the rotating column 11 .

[0037] The staff starts the third motor 15 so that its output shaft drives the second pulley 12 to rotate. Under the transmission action of the transmission belt 13, the rotating shaft 506 drives the first pulley 9, the dredging cone 507 and the crushing teeth 8 to rotate. The rotation of the dredging cone 507 and the crushing teeth 8 enables them to contact the material more fully and crush the material more effectively. This continuous crushing action helps to refine large pieces of material into smaller particles, which is convenient for subsequent processing and discharge.

[0038] In another embodiment of the present invention, a sliding post 14 is slidably provided on the upper surface of the positioning frame 503 , and the upper ends of the two sliding posts 14 are fixedly connected to the lifting plate 505 .

[0039] By providing the slide column 14 , the lifting plate 505 can move stably.

[0040] The working principle of this stainless steel reactor for synthesizing organic chemical raw materials:

[0041] During use, the staff pours the raw materials into the shell 1 through the feed pipe 101, and then the staff starts the first motor 201 to make its output shaft drive the rotating rod 202 to rotate, and the rotating rotating rod 202 drives the stirring blade 203 to rotate, so that the stirring blade 203 can stir the material in the shell 1 and accelerate its mixing. After mixing is completed, the staff opens the sealing valve inside the discharge pipe 102, so that the discharge pipe 102 discharges the material inside the shell 1. When the discharge pipe 102 is blocked, the staff controls the positioning frame 503 to move, so that it moves along the direction of the slide 501 to the bottom of the discharge pipe 102, and then the staff controls the cylinder 504 so that its output end drives the dredging cone 507 to rise, so that the dredging cone 507 contacts the blocked material and dredges the blocked material, thereby completing the dredging of the discharge pipe 102 and avoiding the situation where the internal pressure of the reactor increases and causes a safety accident.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
