A sealing gasket is provided between the sealing cover and the reaction kettle body, and the sealing cover is fixed on the reaction kettle body through fasteners. However, when tightening the fasteners, it is difficult to ensure that the force exerted by each fastener on the sealing gasket is the same, so it is difficult to ensure the sealing performance between the sealing cover and the reaction kettle body. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a sealing structure for a chemical reaction kettle with leakage prevention, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A sealing structure for a chemical reaction kettle with leakage prevention includes a reaction kettle body and a sealing cover. The sealing cover is fixedly installed on the upper surface of the reaction kettle body. A stirring motor is fixedly installed on the upper surface of the sealing cover. Support frames are fixedly installed on both side surfaces of the reaction kettle body. Pull rods are fixedly installed on both side surfaces of the sealing cover.

[0007] Preferably, a toothed ring is movably sleeved on the surface of the reaction kettle body near the lower end. A fixing plate is fixedly installed on the surface of the reaction kettle body and below one side of the toothed ring. A rotating motor is fixedly installed on the lower surface of the fixing plate.

[0008] Preferably, support plates are fixedly installed on both side surfaces of the support frame. A lifting groove is longitudinally opened on the rear surface of the support frame. A threaded rod is movably installed inside the lifting groove. A transmission gear is movably installed on the lower surface of the support frame. Limiting sliding grooves are longitudinally opened on both sides of the lifting groove on the rear surface of the support frame.

[0009] Preferably, the support frame is fixed to the reaction kettle body through the support plate. The output end of the rotating motor is fixed to the transmission gear of the support frame on one side of the reaction kettle body.

[0010] Preferably, limiting sliding strips are longitudinally fixedly installed on the rear surface of the pull rod near both sides. A threaded sleeve block is fixedly installed on the rear surface of the lower end of the pull rod. The threaded sleeve block is sleeved on the surface of the threaded rod. The limiting sliding strips are embedded in the limiting sliding grooves.

[0011] Preferably, the lower end of the threaded rod is fixed to the transmission gear, and the transmission gear meshes with the toothed ring.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by setting the reaction kettle body, the support frame and the pull rod to cooperate with each other, when installing the sealing cover, an external device is used to start the rotating motor, and the rotating motor drives the transmission gear of the support frame on one side of the reaction kettle body to rotate. At this time, the transmission gear drives the toothed ring to rotate, and the rotating toothed ring drives the transmission gear of the support frame on the other side of the reaction kettle body to rotate. The rotating transmission gear drives the threaded rod to rotate. At this time, the pull rod will descend. As the pull rod descends continuously, the sealing cover will be driven to descend until the sealing cover presses on the upper surface of the reaction kettle body. In this way, the sealing gasket pressed by the sealing cover on the reaction kettle body can ensure the sealing performance after the sealing cover is fixed on the reaction kettle body by using fasteners.
