[0029] See also Figure 1-4 A closed cover plate for a reactor comprises a cover plate body 1, a hanging piece 2 and a guide part 3. The hanging pieces 2 are distributed in a ring array on the side of the cover plate body 1. The guide part 3 comprises a connecting plug-in 31, a guide seat 32 and a guide piece 33. The connecting plug-in 31 and the guide seat 32 are distributed along the axis of the cover plate body 1. The connecting plug-in 31 is arranged on the hanging piece 2, the guide seat 32 is located below the connecting plug-in 31, and the guide piece 33 is arranged between the connecting plug-in 31 and the guide seat 32. The guide piece 33 can slide along the guide seat 32.

[0030] The existing reactor sealing cover is usually equipped with components such as a stirring mechanism, an observation window and a feed pipe. After being disassembled from the reactor body, it needs to be separated by hoisting and lifting. The cover body 1 of this embodiment is based on lifting separation. The hoisting parts 2 are installed corresponding to the three points of an equilateral triangle formed by connecting lines on the cover body 1. The connecting plug-ins 31 are vertically connected with the hoisting parts 2 in the same number and are located on the side of the reactor body corresponding to the cover body 1. The guide seat 32 is located on the side of the reactor body, and the guide member 33 is arranged between the connecting plug-in 31 and the guide seat 32.

[0031] Based on the above, after the cover body 1 is separated from the kettle body, it can be connected to the lifting rope of the lifting equipment through the three-point position lifting parts 2. During the lifting process, the existing connecting plug-in 31 moves along the side of the kettle body to guide the separation movement of the cover body 1 and the kettle body. After the connecting plug-in 31 leaves the side of the kettle body, the follow-up guide part 33 moves along the guide seat 32 to guide the lifting movement of the cover body 1 until the upper component of the cover body 1 is detached from the kettle body, and the cover body 1 stops lifting, so as to achieve stable lifting movement of the sealing cover of the reactor, reduce the possibility of shaking during lifting, and avoid contact and collision between the carried components and the kettle body.

[0032] See also Figure 1-4 The side of the cover body 1 is provided with fixing parts 4 distributed in a circular array, and the fixing parts 4 and the hanging parts 2 are distributed alternately.

[0033] Based on the cumbersome assembly and disassembly of the existing sealing cover plate and the kettle body flange connection, the fixing part 4 of the present invention is composed of an ear plate, a pressure rod and a pressure plate. The ear plates are arranged in groups of two on the cover plate body 1 corresponding to the kettle body, and the pressure plate is arranged on the cover plate body 1 corresponding to the ear plate. The pressure rod is rotatably installed between the ear plates, one end of which is located between the pressure plates and abuts against the pressure plate. In this way, the pressure plate is pressed downward by the pressure rod, so that the cover plate body 1 and the kettle body are tightly connected and fixed.

[0034] Corresponding to the three-point setting of the lifting component 2, the number of the fixing components 4 can be set according to the equally divided intervals of the lifting component 2, and the total number of the fixing components 4 in the interval is regarded as a whole and is distributed alternately with the lifting component 2.

[0035] The cover body 1 is connected to the kettle body through a fixing member 4. In this embodiment, a plug hole is provided on the opposite side of the cover body 1. A blocking member 5 is provided on the cover body 1 through the plug hole. The blocking member 5 includes a blocking ring 51 and a fixing member 52. The fixing member 52 is provided between the cover body 1 and the blocking ring 51 through the plug hole, and the blocking ring 51 is in contact with the cover body 1.

[0036] The retaining ring 51 is fixed on the contact side of the cover body 1 and the kettle body by the cooperation of the fixing member 2 52 composed of bolts and nuts and the insertion hole. It can be connected with the cover body 1 and the kettle body and inserted into the inner tank of the kettle body, and can just cover the connection between the cover body 1 and the kettle body, thereby further improving the sealing performance of the cover body 1 after connection.

[0037] See also Figure 1-4 The guide member 33 includes a connecting end 331, a middle support rod 332 and an extension rod 333. The connecting end 331 is arranged on the middle support rod 332, and the extension rod 333 can move along the middle support rod 332. A connecting hole is provided on the connecting plug-in 31, and the connecting end 331 is connected to the connecting plug-in 31 through the connecting hole. The middle support rod 332 is arranged on the guide seat 32, and a card slot is provided on the middle support rod 332. A limiting plate 6 is provided between the middle support rod 332 and the guide seat 32 through the card slot.

[0038] The cover body 1 is guided and lifted based on the guide member 33, which is connected to the internal threaded connection hole on the connecting plug-in 31 through the connection end 331 with an external thread, and cooperates with the movement guidance of the middle support rod 332 and the guide seat 32. When the cover body 1 is lifted, the limit plate 6 is first pulled out of the slot to release the restriction between the guide seat 32 and the middle support rod 332, and then the middle support rod 332 moves upward along the guide seat 32, which can provide vertical direction restriction for the lifting of the cover body 1, thereby ensuring the stability of the subsequent lifting movement of the cover body 1.

[0039] It should be noted that the lengths of the stirring mechanisms inserted into the kettle body are different. During the lifting process of the cover body 1, the middle support rod 332 and the extension rod 333 are telescopically connected. The extension rod 333 finally rests against the guide seat 32 to extend the rising stroke of the middle support rod 332, and the stirring mechanism is completely detached from the kettle body in cooperation with the lifting of the cover body 1.

[0040] Based on the threaded connection between the connecting end 331 and the connecting plug-in 31, in this embodiment, the extension rod 333 may be provided with an operating end 7 without external support, and a support seat 8 is provided outside the operating end 7. The operating end 7 is connected to the extension rod 333 through a hexagonal socket at the end, and the supporting seat 8 serves as a support for the operating end 7, so that it is convenient for the staff to insert the operating end 7 through a tool at the ground end, rotate the extension rod 333, and drive the middle support rod 332 to make the connecting end 331 turn into the connecting plug, and then be separated from the cover body 1.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
