Abstract

The utility model relates to a stainless steel reaction kettle, including the cauldron body, agitating unit and landing leg, the cauldron body comprises upper cover and cylindrical barrel, agitating unit comprises motor, speed reducer, shaft coupling, (mixing) shaft and stirring rake, two -layer stirring rake about setting up on the (mixing) shaft, the stirring rake is being located the impeller formula stirring rake on upper strata and the U -shaped arm stirring tooth that is located the lower floor respectively, and U -shaped arm opening sets up up, and U -shaped arm back sets up at the bottom of being close to the reation kettle cauldron, barrel lateral part upper end position is provided with a catalyst filling tube, a plurality of ejection of compact apertures have been seted up on the catalyst filling tube. The utility model discloses have three stirring rakes, effective messenger mixes the liquid intensive mixing, prevents to sink at the end, improves the speed of reaction, and the shortening reaction time, the catalyst filling tube can make the interior material homodisperses such as catalyst of absorbed reation kettle in reation kettle, makes the reaction heat equipartition that produces simultaneously, and it influences product synthesis yield to be difficult for leading to the fact reaction heat to concentrate.

Description

A kind of stainless steel cauldron

Technical field

This utility model is related to chemical industry technical field, is specifically designed a kind of stainless steel cauldron.

Background technology

Reactor is usually used in the industries such as petrochemical industry, rubber, pesticide, medicine, in order to complete sulfonation, nitrification, hydrogenation, hydrocarbon Technical process, and the consersion unit of many other technical processs of organic dyestuff and intermediate such as change, be polymerized, being condensed.At present Stainless steel cauldron dog-house be generally positioned at kettle upper end, when feeding intake, material direct plunges in reactor, with material in kettle Mixing.However, some additions account for the less material of overall reaction material proportion direct plungeing into, such as catalyst etc., easily cause kettle This material local concentration interior is too high, causes the side reactions such as Organic substance implode, the result of impact reaction or the quality of product.For anti- Answer the original structure of kettle, be badly in need of to the reactor re-optimization design under prior art.

Utility model content

This utility model purpose is to overcome the deficiencies in the prior art to propose a kind of catalyst and feed intake uniformly not Rust steel reactor.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of stainless steel cauldron, including kettle, Agitating device and supporting leg, described kettle is made up of upper cover and cylindrical tube；Described agitating device by motor, reductor, Shaft coupling, shaft and stirring paddle composition；Reductor is connected, reductor connects shaft coupling, shaft coupling is even below described motor Connect shaft；Shaft main body penetrates upper cover and is vertically arranged in kettle；Upper and lower two-layer stirring paddle is arranged on described shaft； The u shape arm stirrer gear that described stirring paddle is respectively the impeller type stirring blade being located at upper strata and is located at lower floor, u shape arm is opening up to be set Put, u shape arm back is arranged near reactor bottom；Described cylinder sidepiece upper end position is provided with a catalyst addition tube；Institute State catalyst addition tube and pierce in cylinder tailing edge cylinder inboard wall from cylinder vertically downward to above cylinder bottom；Described catalyst charging Multiple discharging apertures are offered on pipe.

Preferably, the impeller type stirring blade on described shaft is provided with two-layer, and two-layer stirring paddle and u shape arm stirrer gear exist Spaced set on shaft.

Preferably, described discharging aperture spaced set.

Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that

Stainless steel cauldron of the present utility model, it has a pair of u shape arm stirrer gear of two-layer stirring paddle and lower section, effectively makes Mixed liquor is sufficiently mixed, and prevents from sinking to the bottom, and improves the speed of reaction, shortens the response time；Catalyst addition tube and its multiple discharging The design of aperture, can make the catalyst and other material in input reactor be dispersed in reactor, make the anti-of generation simultaneously Should be hot uniform, do not easily cause reaction heat and concentrate impact product synthesis yield.

Brief description

Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:

Accompanying drawing 1 is structural representation of the present utility model.

Wherein: 1, supporting leg；2nd, upper cover；3rd, cylinder；4th, motor；5th, reductor；6th, shaft coupling；7th, shaft；8th, leaf Wheeled stirring paddle；9th, u shape arm stirrer gear；10th, catalyst addition tube；11st, discharging aperture.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.

In conjunction with shown in accompanying drawing 1, a kind of stainless steel cauldron described in the utility model, including kettle, agitating device and Lower limb 1, described kettle is made up of upper cover 2 and cylindrical tube 3；Described agitating device by motor 4, reductor 5, shaft coupling 6, Shaft 7 and stirring paddle composition；Described motor 4 lower section connects reductor 5, and reductor 5 connects shaft coupling 6, and shaft coupling 6 connects Shaft 7；Shaft 7 main body penetrates upper cover 2 and is vertically arranged in kettle；Upper and lower two-layer stirring is arranged on described shaft 7 Oar；The u shape arm stirrer gear 9 that described stirring paddle is respectively the impeller type stirring blade 8 being located at upper strata and is located at lower floor, its u shape arm is opened Mouth is arranged upward, and u shape arm back is arranged near reactor bottom；Described cylinder 3 sidepiece upper end position is provided with a catalyst Charge pipe 10；Described catalyst addition tube 10 pierces in cylinder 3 tailing edge cylinder 3 inwall from cylinder 3 vertically downward to cylinder bottom Side；Multiple discharging apertures 11 are offered on described catalyst addition tube 10；Described discharging aperture 11 spaced set, can make throwing Enter the catalyst and other material in reactor to be dispersed in reactor, make the reaction heat of generation uniform simultaneously, do not easily cause anti- Heat should concentrate impact product synthesis yield.

Further illustrate, the impeller type stirring blade 8 on described shaft is provided with two-layer, two-layer stirring paddle 8 and u shape arm stir Teeth 9 spaced set on shaft 7, effectively makes mixed liquor be sufficiently mixed, prevents from sinking to the bottom, and improves the speed of reaction, shortens Response time.

The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model System.All employing equivalents or equivalence replacement and the technical scheme that formed, all fall within this utility model rights protection scope it Interior.
