Description

The special carburizing reagent still of a kind of 2-hydroxyl-3-naphthoic acid
Technical field
The utility model belongs to field of chemical equipment, is specifically related to the special carburizing reagent still of a kind of 2-hydroxyl-3-naphthoic acid.
Background technology
Need in carbonization kettle, utilize chuck heat-conducting medium that heating material to 270 DEG C is dewatered fully, reacted in carboxylated operation in the production of 2-hydroxyl-3-naphthoic acid, in addition owing to being gas-solid phase reaction, and along with the carrying out of reaction, the granule density of reaction system significantly can change in kettle, like this in order to ensure carrying out smoothly of reaction, guarantee that reaction paste mixes, just need to utilize the paddle arranged in carbonization kettle effectively to stir reaction paste, which adds energy consumption; In addition, in actual motion, because the pressure space between relatively large reactor and chuck is comparatively large, and the mobility of heat-conducting medium is fast, and therefore heating effect is poor, is difficult to reach desirable temperature.
Summary of the invention
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of special carburizing reagent still of 2-hydroxyl-3-naphthoic acid that reaction paste can be made to mix faster, and its stirring efficiency is high, and energy consumption is low, and result of use is good.
The technical scheme in the invention for solving the technical problem is: the special carburizing reagent still of a kind of 2-hydroxyl-3-naphthoic acid, comprise kettle cover, kettle and the cone end, described kettle cover and the cone end, are fixed in described kettle two ends respectively, described kettle cover is provided with charging aperture and manhole, shaft is provided with in kettle, the inside sidewalls of described kettle arranges the hollow channel-shaped dividing plate of multiple vertical layout, multiple slurry passage is formed between described hollow channel-shaped dividing plate and kettle madial wall, the upper end of described hollow channel-shaped dividing plate is lower than the lower limb face of kettle cover, the lower end of described hollow channel-shaped dividing plate extends to the top edge face at the cone end.
Further, be also provided with still external jacket, be provided with hydraulic barrier in described still external jacket at described kettle and the cone end, described hydraulic barrier subsection interleaving in still external jacket is arranged.
The beneficial effects of the utility model are: a kind of 2-hydroxyl-3-naphthoic acid of the present utility model special carburizing reagent still stirring efficiency is high, and reaction paste can be made to mix faster, and energy consumption is low; The hollow channel-shaped dividing plate that described kettle madial wall is arranged, can eliminate the whirlpool produced in whipping process on the one hand, improve mixing effect; Slurry passage water conservancy diversion that the reaction paste of kettle bottom is formed by described hollow channel-shaped dividing plate and kettle madial wall also can be made on the other hand to kettle upper strata, and be convenient to reaction paste and mix faster, result of use is good; In addition, be provided with hydraulic barrier in described still external jacket, the turbulent extent of thermal medium can be increased, improve the thermal efficiency.

Fig. 2 is A-A sectional view in Fig. 1.In figure:
1, kettle cover, 2. kettle, 3. hydraulic barrier, 4. still external jacket, 5. charging aperture, 6. shaft, 7. hollow channel-shaped dividing plate, 8. paddle, 9. bores the end.
Detailed description of the invention
The technical solution of the utility model is further illustrated below by specific embodiment.
As shown in Figure 1-2: the special carburizing reagent still of a kind of 2-hydroxyl-3-naphthoic acid, comprise kettle cover 1, kettle 2 and the cone end 9, described kettle cover 1 and the cone end 9, are fixed in described kettle 2 two ends respectively, and described kettle cover 1 is provided with charging aperture 5 and manhole; Shaft 6 is provided with in kettle, shaft 6 is provided with paddle 8, the inside sidewalls of described kettle 2 arranges the hollow channel-shaped dividing plate 7 of multiple vertical layout, multiple slurry passage is formed between described hollow channel-shaped dividing plate 7 and kettle 2 madial wall, the lower end of described hollow channel-shaped dividing plate 7 extends to the top edge face at the cone end 9, the upper end of described hollow channel-shaped dividing plate 7 is lower than the lower limb face of kettle cover 1, described hollow channel-shaped dividing plate 7 not only can eliminate whirlpool, improve mixing effect, increase less turbulence, the fluctuation of stirring load can also be reduced simultaneously, make power consumption keep stable.
In addition, described kettle 2 is under the stirring of paddle 8, and the reaction paste at the part cone end 9 enters into hollow channel-shaped dividing plate 7, and upwards flows along the slurry passage formed between hollow channel-shaped dividing plate 7 and kettle 2 madial wall, and final water conservancy diversion is to the upper strata of reaction paste; Or make the reaction paste on upper strata through hollow channel-shaped dividing plate 7 water conservancy diversion to lower floor, thus be convenient to reaction paste and mix faster, so both add the stability of reaction, turn improve the quality of product.
Further, still external jacket 4 is also provided with at described kettle 2 and the cone end 9, hydraulic barrier 3 is provided with in described still external jacket 4, described hydraulic barrier 3 subsection interleaving in still external jacket 4 is arranged, in still external jacket 4, the number of hydraulic barrier 3 is multiple, can increase the turbulent extent of thermal medium, improves the thermal efficiency, can also eliminate the flow dead of thermal medium, described thermal medium is preferably conduction oil simultaneously.
The special carburizing reagent still of a kind of 2 hydroxyl-3-naphthoic acid of the present utility model, stirring efficiency is high, and reaction paste can be made to mix faster, and energy consumption is low; The hollow channel-shaped dividing plate 7 that described kettle 2 madial wall is arranged, can eliminate the whirlpool produced in whipping process on the one hand, improve mixing effect; Slurry passage water conservancy diversion that the reaction paste of kettle 2 bottom is formed by described hollow channel-shaped dividing plate 7 and kettle 2 madial wall also can be made on the other hand to kettle 2 upper strata, and be convenient to reaction paste and mix faster, result of use is good; In addition, be provided with hydraulic barrier 3 in described still external jacket 4, the turbulent extent of thermal medium can be increased, improve the thermal efficiency.
Except technical characteristic described in description, be those skilled in the art known technology.
