Description

Technical Field

[0001] This utility model relates to the field of oxidation reactor technology, specifically to an oxidation reactor for preparing uniformly mixed m-cresol. Background Technology

[0002] m-Cresol is an organic chemical with a nearly colorless, pale purple-red, or pale brownish-yellow clear liquid appearance, accompanied by an odor similar to phenol, with a slight burnt smell. It has a wide range of main uses, including as a raw material for synthetic resins, insulating varnishes, and antioxidants, as well as as a disinfectant and solvent. However, an oxidation reactor is required in the oxidation preparation process of m-cresol.

[0003] Currently, when preparing m-cresol by oxidation inside an oxidation reactor, the raw materials need to be stirred to ensure uniform mixing. However, the stirring device in the current oxidation reactor can only stir the raw materials for m-cresol oxidation in one direction. Due to the different densities of the raw materials, stratification is likely to occur, resulting in uneven mixing and reduced preparation efficiency. Therefore, we propose an oxidation reactor for preparing m-cresol with uniform mixing. Utility Model Content

[0004] The purpose of this invention is to provide an oxidation reactor for preparing m-cresol with uniform mixing. This reactor allows for horizontal and vertical stirring of the raw materials inside, improving the uniformity and efficiency of mixing and thus increasing preparation efficiency. It solves the problem that current oxidation reactors only allow for unidirectional stirring of the raw materials, leading to stratification due to differences in density and resulting in uneven mixing and reduced preparation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxidation reactor for preparing uniformly mixed m-cresol, comprising an oxidation reactor body, a reactor lid, and a stirring motor. The reactor lid is fixedly installed on the upper surface of the oxidation reactor body, and a fixing frame is fixedly installed on the upper surface of the reactor lid. A reciprocating screw is rotatably connected to the top of the inner wall of the fixing frame, and a stirring shaft is fixedly connected to the end of the reciprocating screw. Horizontal stirring blades are fixedly installed on the outer surface of the stirring shaft, and a slider is movably sleeved on the outer surface of the reciprocating screw. Horizontal plates are fixedly connected to both sides of the outer surface of the slider, and vertical rods are fixedly connected to the lower surfaces of the two horizontal plates. Upper and lower stirring blades are fixedly installed on the outer surface of the vertical rods, and both the upper and lower stirring blades and the horizontal stirring blades are located inside the oxidation reactor body.

[0006] Preferably, a stirring motor is fixedly mounted on the upper surface of the fixed frame, and the end of the output shaft of the stirring motor is fixedly connected to the upper surface of the reciprocating screw.

[0007] Preferably, a sealing ring is fixedly installed on the upper surface of the vessel lid at the positions of the vertical rod and the stirring shaft, and the vertical rod and the stirring shaft pass through the sealing ring respectively.

[0008] Preferably, a feed valve is fixedly connected to the upper surface of the reactor lid, and a discharge valve is fixedly connected to the lower surface of the oxidation reactor body.

[0009] Preferably, a brush ring is fixedly installed on the upper surface of the upper and lower stirring blades near the edge.

[0010] Preferably, four support legs are fixedly connected in a ring array at equal intervals near the edge of the lower surface of the oxidation reactor body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up an oxidation reactor body, reactor lid, stirring motor, reciprocating screw, slider, stirring shaft, horizontal stirring blades, horizontal plate, vertical rod, and upper and lower stirring blades, achieves the effect of horizontal and vertical stirring of the raw materials inside the oxidation reactor during the oxidation preparation of m-cresol, thereby improving the mixing uniformity and efficiency of the raw materials and thus improving the preparation efficiency. The stirring motor drives the reciprocating screw to rotate, which in turn drives the stirring shaft and horizontal stirring blades to rotate. The horizontal stirring blades stir the raw materials for m-cresol oxidation preparation inside the oxidation reactor body horizontally. At the same time, the rotation of the reciprocating screw drives the slider to move the horizontal plate and vertical rod up and down reciprocally. The upper and lower stirring blades on the vertical rod can stir the raw materials for m-cresol oxidation preparation inside the oxidation reactor body vertically, thus ensuring that the raw materials for m-cresol oxidation preparation inside the oxidation reactor body are fully mixed, improving the mixing uniformity and efficiency.

[0013] 2. By setting a brush ring, the upper and lower stirring blades can scrape off the raw materials adhering to the inner wall of the oxidation reactor body when they move up and down in the reciprocating motion inside the oxidation reactor body, so as to prevent scale formation on the reactor wall and also facilitate the mixing of raw materials.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0020] like Figures 1-4 As shown, this utility model proposes an oxidation reactor for preparing m-cresol with uniform mixing, comprising an oxidation reactor body 2, a reactor lid 3, and a stirring motor 5. The reactor lid 3 is fixedly installed on the upper surface of the oxidation reactor body 2, and a feed valve 8 is fixedly connected to the upper surface of the reactor lid 3. Toluene, oxidant, catalyst, and other raw materials for the preparation of m-cresol oxidation are added into the oxidation reactor body 2 through the feed valve 8. A discharge valve 16 is fixedly connected to the lower surface of the oxidation reactor body 2, and the prepared m-cresol is discharged through the discharge valve 16. A fixing frame 4 is fixedly installed on the upper surface of the reactor lid 3. The fixing frame 4 is shaped like an "n" in front of the main view. A reciprocating screw 6 is rotatably connected to the top of the inner wall of the fixing frame 4. The reciprocating screw 6 and the fixing frame 4 are rotatably connected by a bearing. The stirring motor 5 is fixedly installed on the upper surface of the fixing frame 4. The output shaft of the stirring motor 5 is fixedly connected to the upper surface of the reciprocating screw 6. The stirring motor 5 drives the reciprocating screw 6 to rotate. The end of the reciprocating screw 6 is fixedly connected to the stirring shaft 10, which passes through the kettle cover 3. A horizontal stirring blade 9 is fixedly installed on the outer surface of the stirring shaft 10. A slider 11 is movably sleeved on the outer surface of the reciprocating screw 6. A horizontal plate 12 is fixedly connected to both sides of the outer surface of the slider 11. A vertical rod 13 is fixedly connected to the lower surface of both horizontal plates 12. The vertical rod 13 passes through the kettle cover 3. An upper and lower stirring blade 14 is fixedly installed on the outer surface of the vertical rod 13. The upper and lower stirring blades 14 and the horizontal stirring blades 9 are all located inside the oxidation kettle body 2. Four support legs 1 are fixedly connected in a ring array at equal intervals near the edge of the lower surface of the oxidation kettle body 2.

[0021] In use, the stirring motor 5 drives the reciprocating screw 6 to rotate, which in turn drives the stirring shaft 10 and the horizontal stirring blades 9 to rotate. The horizontal stirring blades 9 stir the raw materials for the preparation of m-cresol oxidation inside the oxidation vessel body 2 in a horizontal direction. At the same time, the rotation of the reciprocating screw 6 drives the slider 11 to move the horizontal plate 12 and the vertical rod 13 up and down. The up and down stirring blades 14 on the vertical rod 13 can stir the raw materials for the preparation of m-cresol oxidation inside the oxidation vessel body 2 in an up and down manner, thus making the raw materials for the preparation of m-cresol oxidation inside the oxidation vessel body 2 fully mixed and improving the uniformity and efficiency of the mixing.

The sealing rings 7 are used to seal the gap at the junction between the vertical rod 13 and the stirring shaft 10 and the reactor cover 3. A brush ring 15 is fixedly installed on the upper surface of the upper and lower stirring blades 14 near the edge.

[0023] In this embodiment, when the upper and lower stirring blades 14 reciprocate up and down inside the oxidation reactor body 2, the brush ring 15 can scrape off the raw materials adhering to the inner wall of the oxidation reactor body 2 to prevent scale buildup on the reactor wall, and also facilitate the mixing of raw materials.
