Embodiment 1
[0043] see Figure 1 to Figure 6 , This embodiment provides a feed rotary plate valve of a reaction kettle, which includes a valve body 1, a cover plate 2 and a pressing part. The first end of the valve body 1 is communicated with the reaction kettle, and the second end is detachably connected to the cover plate 2 through at least two pressing parts. The surface of the valve body 1 in contact with the cover plate 2 is a sealing surface, a groove is provided on the sealing surface, and a sealing ring 3 is placed in the groove. The pressing part is connected to the valve body 1 for pressing the cover plate 2 and the sealing surface.
[0044] The present invention adopts a fully open design. After the cover plate 2 is removed from the valve body 1, the sealing ring 3 is exposed to the outside, and the sealing ring 3 can be easily replaced; and after the cover plate 2 is opened, the inside of the valve (ie The inside of the valve body 1 and the side of the cover plate 2 in conta...
Embodiment 2
[0054] see Figure 1 to Figure 6 , this embodiment provides a feed rotary valve of the reaction kettle. On the basis of Embodiment 1, a rotary disk drive part and a cover plate driving part are set to realize the automatic opening and closing of the feeding rotary valve of the reaction kettle. .
[0055] Among them, the output end of the turntable driving part is connected with the turntable 6 to drive the turntable 6 to rotate; the output end of the cover plate driving part is connected with the cover plate 2 and used to drive the cover plate 2 to move to open or close the first valve body 1 two ends.
[0056] Specifically, the turntable driving part may be a first air cylinder, the first air cylinder is fixed on the external platform, and the output end is rotatably connected to the turntable 6 .
[0057] The cover plate driving part may include a second air cylinder and a lever. A mounting seat is connected to the outer side wall of the valve body 1, the second cylinder ...
Embodiment 3
[0061] see Image 6 , this embodiment provides a reaction kettle, the reaction kettle is provided with the feed rotary valve of the reaction kettle provided in Example 1 or / and Example 2.
[0062] The solidraw material feeding direction 10 of the reaction kettle is facing the second end of the valve body 1. After the cover plate 2 is removed from the second end of the valve body 1, the solidraw material can enter the reaction kettle from the solidraw material feeding direction 10. The medium pressure direction 11 of the solid raw material after the stirring reaction is opposite to the feeding direction 10 of the solid raw material.
[0063] At the same time, due to the fully open design of the feeding rotary plate valve of the reaction kettle, its unique switch structure and the design position of the sealing ring 3, the replacement of the sealing ring 3 and the cleaning of the glue attachments inside the valve can be used to feed the reaction kettle. At the same time, it ...

Abstract
The invention discloses a feed rotary plate valve of a reaction kettle and a reaction kettle provided with the feed rotary plate valve of the reaction kettle at the feeding end. The feed rotary plate valve of the reaction kettle comprises a valve body, a pressing part and cover. The first end of the valve body is communicated with the reaction kettle, and the second end is detachably connected with a cover plate through the pressing part. The surface of the valve body in contact with the cover plate is a sealing surface. The sealing surface is provided with a groove, and the groove is provided with a seal lock up. The pressing part is connected to the valve body for pressing the cover plate and the sealing surface. After the cover plate is removed from the valve body, the sealing ring is exposed to the outside, which can be easily replaced and replaced; and after the cover plate is opened, the inside of the valve (that is, the inside of the valve body and the side of the cover plate in contact with the sealing surface) It is also completely exposed, which is convenient for cleaning the glue attachment inside the valve. Therefore, the present invention does not need to disassemble the valve (only need to disassemble the cover plate from the valve body), so that the sealing ring can be replaced and the glue adhered inside the valve can be cleaned.
Description
technical field [0001] The invention belongs to the field of reaction kettles, and in particular relates to a feed rotary plate valve of a reaction kettle and a reaction kettle. Background technique [0002] At present, some process media will produce glue phenomenon during the heating reaction of the reactor (like glue is generally bonded to the metal surface), such as: the aldehyde gas generated by the heating reaction of primary steam and secondary steam in the furfural production process. In the production process, there will be a phenomenon of gelation, which is attached to the valve and has strong adhesion and high hardness, which will cause the valve to be stuck and closed after a period of time. Since medium leakage will cause environmental pollution, after a period of time (about two weeks in the furfural production process), it is necessary to disassemble the valve and replace the seal to clean up the glue attached to the valve. This not only results in production...
