Technical Field

The utility model relates to the technical field of kitchen slurry treatment devices, in particular to an upflow Miller plate steam heater for kitchen slurry.

Background

At present, the heating mode of domestic organic slurry generally has the problems that the using effect is very different, and the problems are more, for example: the sleeve type heating heat exchanger has the advantages that the sleeve is additionally arranged outside a pipeline, the slurry is conveyed inside the pipeline, and the heat source is conveyed outside the pipeline to heat the slurry, so that the blockage is avoided, the space required by a heater is huge, a 100-square heating system needs a sleeve with the length of 130 meters, and the cost is high and the efficiency is low; spiral plate heat exchanger, this equipment are rolled up by corrosion resistant plate is compound to be made, are used for the heat transfer of industrial chemicals more by the nonrust steel column as supporting between the spiral plate, have better heat transfer effect, and is small, efficient, nevertheless because contain a lot of filiform impurity in the organic thick liquid, twine on the constructional column in this equipment to often cause equipment to block up. The inside of the heat exchanger is completely blocked, and sometimes carbonization is caused to scrap equipment; steam ejector because the heat exchanger selects the difficulty, has directly adopted the steam ejector mode to heat organic thick liquid on many projects at present, has nevertheless solved the heating problem like this, but has leaded to a large amount of purified water to have got into the thick liquid, leads to the pollutant to increase, and the cost increases, and other still tank body embeds coil pipe heater tank body wall intermediate layer heaters etc. have all had the heating efficiency low, and is chronic, and the space occupies big problem and can't solve.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a kitchen slurry steam heater which is high in heating efficiency and small in occupied space, aiming at the problems in the background technology.

The technical scheme of the utility model is as follows: upflow formula miller board meal kitchen thick liquid steam heater, including the shell body, the inboard of shell body is fixed with interior casing, form sealed annular inner chamber between interior casing and the shell body, the fixed plate that sets up about through two is fixed with a plurality of annular miller boards of establishing layer upon layer cover in the annular inner chamber, and is a plurality of annular miller board separates annular inner chamber out a plurality of thick liquid passageways, the upside intercommunication of annular miller board is fixed with steam inlet, the downside intercommunication of annular miller board is fixed with the comdenstion water export, and the downside intercommunication of thick liquid passageway is fixed with the thick liquid import, all be fixed with fixed plate, upside about the annular miller board form a collection thick liquid inner chamber between fixed plate and the last casing, collection thick liquid inner chamber intercommunication is fixed with out the thick liquid mouth.

Preferably, the lower side of the outer shell is a lower cone shell, and a sand discharge valve is installed on the lower side of the lower cone shell.

Preferably, the upper shell, the outer shell and the lower cone shell are connected through flange bolts.

Preferably, the lower side of the inner shell is fixedly connected with the lower cone shell through a support rod.

Preferably, the slurry channels are equally spaced.

Compared with the prior art, the utility model has the following beneficial technical effects:

1. the annular channel formed by a plurality of groups of annular Miller plates enters the organic slurry from the bottom tangential direction to form fast flowing no-flow, so that the organic slurry flows circularly and rises between the Miller plates along the annular direction, the stroke distance of the slurry is increased, the heat exchange efficiency is increased, and the occupied space is reduced.

2. Utilize annular miller board, interior casing and shell to form annular intermediate layer, let in steam, the characteristics on steam heating ring layer can evenly spread, the thick liquid passageway that the ring layer that is formed by the nevertheless different diameters of multilayer simultaneously is as the passageway of meal kitchen thick liquid, accomplishes the heat transfer between steam and the meal kitchen thick liquid, realizes the heating to the thick liquid, and heat transfer process just becomes very simple, has practiced thrift a large amount of costs for the thick liquid heating.

3. The distance between each circle of layers is the same due to the adoption of the annular multi-layer Miller plate structure, and meanwhile, the Miller plates are of a stable structure of the circular barrel body, any distance device is not used among the Miller plates of each layer, and no element capable of winding or blocking materials in the slurry is arranged in the channel, so that a lot of impurities in the slurry are not removed in the front-end process.
