Embodiment 1

[0043] see Figure 1 to Figure 6 , This embodiment provides a feed rotary valve for a reaction kettle, including a valve body 1, a cover plate 2 and a pressing part. The first end of the valve body 1 communicates with the reactor, 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, and a groove is arranged on the sealing surface, and a sealing ring 3 is placed in the groove. The pressing part is connected to the valve body 1 and is used 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 disassembled from the valve body 1, the sealing ring 3 is exposed outside, and the sealing ring 3 can be easily replaced; and after the cover plate 2 is opened, the inside of the valve (i.e. The inside of the valve body 1 and the side in contact with the sealing surfac...

Embodiment 2

[0054] see Figure 1 to Figure 6 , this embodiment provides a feed rotary valve for the reactor. On the basis of Embodiment 1, a turntable drive unit and a cover plate drive unit are provided to realize the automatic opening and closing of the feed rotary valve for the reactor. .

[0055] Wherein, the output end of the turntable drive part is connected with the turntable 6 for driving the turntable 6 to rotate; the output end of the cover plate drive part is connected with the cover plate 2 for driving 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 cylinder, the first cylinder is fixed on the external platform, and the output end is connected to the turntable 6 in rotation.

[0057] The deck driving part may include a second air cylinder and a lever. The mounting seat is connected on the outer wall of the valve body 1, the second cylinder can be fixed on the same external platform ...

Embodiment 3

[0061] Please see Figure 6 , This embodiment provides a reaction kettle, the reaction kettle is provided with the feed rotary valve of the reaction kettle as provided in Example 1 or / and Example 2.

[0062] The solid raw material feeding direction 10 of the reactor 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 solid raw material can enter the reactor from the solid raw material feeding direction 10. And 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, since the feed rotary valve of the reactor adopts a fully open design and its unique switch structure and the design position of the sealing ring 3, it is possible to replace the sealing ring 3 and clean the glue attachment inside the valve. At the same time, it also needs to disassemble the valve, saving time and effor...

Abstract

The invention discloses a feeding rotary plate valve of a reaction kettle and the reaction kettle with the feeding end provided with the feeding rotary plate valve of the reaction kettle. The feedingrotary plate valve of the reaction kettle comprises a valve body, a pressing portion and a cover plate. The first end of the valve body communicates with the reaction kettle, the second end of the valve body is detachably connected with the cover plate through the pressing portion, the surface, making contact with the cover plate, of the valve body is a sealing surface, a groove is formed in the sealing surface, and a sealing ring is contained in the groove. The pressing portion is connected to the valve body and used for pressing the cover plate and the sealing surface. After the cover plateis detached from the valve body, the sealing ring is exposed outside so that the sealing ring can be conveniently replaced; and after the cover plate is opened, the interior of the valve (namely, theinterior of the valve body and the surface, making contact with the sealing surface, of the cover plate) is also completely exposed outside, and adhesive attachments in the valve are convenient to remove. Thus, the valve does not need to be disassembled (only the cover plate needs to be disassembled from the valve body), the sealing ring can be replaced, and the adhesive attachments in the valve can be removed.

Description

technical field [0001] The invention belongs to the field of reaction kettles, and in particular relates to a feed rotary plate valve of the reaction kettle and the reaction kettle. Background technique [0002] At present, some process media will produce gelation phenomenon (like glue on the metal surface) during the heating reaction process of the reactor, such as: aldehyde gas produced by the heating reaction of primary steam and secondary steam in the furfural production process In the production process, there will be gelation phenomenon, which will adhere to the valve with strong adhesion and high hardness, which will cause the valve to be stuck and closed after a period of time, and the sealing surface of the valve will be rough and glued, causing the valve to leak. Since the leakage of the medium will cause environmental pollution, after a period of time (the furfural production process is about two weeks or so), it is necessary to disassemble the valve and replace t...
