Abstract
The utility model discloses a kind of sodium hydrosulfite drying kettle, including upper cover, low head, inner cylinder, outer coil pipe, inlet port and outlet port, the outer coil pipe and inner cylinder, upper cover and low head weld, and are provided with Heating medium on the outer coil pipe, and the heat transfer effect is the mm of 10 mm ~ 16；The utility model replaces external jacket using outer coil pipe, can effectively reduce inner cylinder pressure, greatly reduces inner tube wall thickness, heat exchange efficiency increase, significantly improves drying effect.
Description
Technical field
Drying kettle is the utility model is related to, more particularly, to a kind of sodium hydrosulfite drying kettle.
Background technology
Traditional sodium hydrosulfite drying kettle mainly includes：Upper cover, inner cylinder, low head, external jacket, filter plate filter cloth component, spiral shell
The components such as rotating plate；Include feed inlet at the same time, discharge port and use flange adds bolt to seal.
Main drying process is as follows：
1. charging and filtering：Sodium hydrosulfite suspension is put into drying kettle by feed inlet, falls on filter plate and filter cloth component, adopts
With pressure filtration, mother liquor is drained by filter plate and filter cloth by mother liquor pipe, and sodium hydrosulfite solid is retained down.
2. washing：After the completion of filtering, methanol washing is added, starts drying after having washed.
3. drying：92 ~ 98 degree of hot water is passed through in external jacket, heating drying is carried out to sodium hydrosulfite.
4. after the completion of drying, stop at and hot water is passed through in external jacket.It is changed to be passed through cold water in external jacket.To sodium hydrosulfite into
Row cooling.
5. after the completion of cooling, manually turning on the bolt of discharge port, flange is opened, insurance powder material is released.
It is primarily present problems with：
1. the hot water being passed through in external jacket has certain pressure head（P=0.2~0.3MPa）, therefore equipment inner cylinder, upper cover, under
End socket bears external pressure, and when designing calculating, wall thickness is thicker（14~18mm）, reduce heat exchange efficiency（Wall thickness is thicker, heat exchange efficiency
It is poorer）.
2. the distance between external jacket and equipment inner cylinder are 50 ~ 100mm, one is provided between external jacket and equipment inner cylinder
The spiral plate of fixed number amount, takes a shortcut for reducing hot water or cold water, improves heat transfer effect.But, the work that this spiral plate rises
With very limited, the efficiency being heated or cooled is low, causes drying time and cooling time to grow.
3. releasing insurance powder material every time, it is required for manually turning on the bolt of drain hole, opens flange, labor intensity is big,
Efficiency is low.
The content of the invention
The defects of in order to overcome the prior art nuclear issue, the present invention designs a kind of New typs powder for keeping foodstaff fresh drying kettle, to improve
Heat exchange efficiency, improves drying effect.
The utility model in order to solve prior art problem used by technical solution it is as follows：
A kind of sodium hydrosulfite drying kettle, including upper cover, low head, inner cylinder, outer coil pipe and feed inlet, the outer coil pipe with it is interior
Welded between cylinder, upper cover and low head, Heating medium is provided with the outer coil pipe.
Further, filter assemblies are further included, the filter plate assembly is arranged at inner cylinder lower part.
Further, the filter assemblies include filter plate and filter cloth.
Further, a discharge port is further included, the discharge port is provided with a bolt.
Further, in order to reduce labor intensity, the discharge port is provided with valve, the valve include hand,
Electrodynamic type or pneumatic type valve.
Further, the heat transfer effect is 10 ~ 16 mm.
Further, the heat transfer effect is 13 mm.
It is as follows by using above-mentioned technical proposal, the beneficial effects of the utility model：
1. original external jacket is changed to outer coil pipe so that inner cylinder, upper cover and low head are not subject to external pressure, and wall thickness can subtract
Thin 2 ~ 4 mm, after wall thickness reduction, heat exchange efficiency increase；Meanwhile hot water and cold water do not have shortcut to walk, and improve heating and cooling
Effect；
2. the flange of discharge port, which is changed to a valve, no longer needs mutual disassembly's bolt, labor intensity is reduced, improves work
Efficiency.
Brief description of the drawings
Fig. 1 is sodium hydrosulfite drying kettle schematic diagram；
Fig. 2 is prior art sodium hydrosulfite drying kettle schematic diagram.
Embodiment
The embodiment of the utility model is described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Embodiment
As shown in Figure 1, a kind of sodium hydrosulfite drying kettle, including upper cover 1, low head 3, inner cylinder 2, outer coil pipe 4-1 and charging
Mouth K, welds between outer coil pipe 4-1 and inner cylinder 2, upper cover 1 and low head 3, Heating medium 6 is provided with outer coil pipe 4-1；Also wrap
Filter assemblies 5 are included, the filter plate assembly 5 is arranged at 2 lower part of inner cylinder；Filter assemblies 5 include filter plate and filter cloth；Sodium hydrosulfite suspension
Drying kettle is put into by feed inlet, is fallen on filter plate and filter cloth component, using pressure filtration, mother liquor is by filter plate and filter cloth by mother
Liquid pipe is drained, and sodium hydrosulfite solid is retained down.
A discharging port A is further included, the discharging port A includes bolt C；Discharging port A is provided with valve A-1, turns on discharging
The bolt C of mouth, opens valve A-1, and insurance powder material is released.
Heat transfer effect is 13 mm, and 3mm can be thinned compared to traditional insurance kettle heat transfer effect.
As shown in Fig. 2, traditional sodium hydrosulfite drying kettle mainly includes：Upper cover 1, inner cylinder 2, low head 3, external jacket 4, filter
Plate filter cloth component and the grade component of spiral plate 6；Include feed inlet K, discharging port A at the same time（Sealed using flange plus bolt C）.
Obviously, above-described embodiment is only intended to clearly illustrate the technical solution of the utility model example, and simultaneously
Non- is the restriction to the embodiment of the utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other variations or changes in different ways.That is made within the spirit and principles of the invention is any
Modifications, equivalent substitutions and improvements etc., should be included within the protection of the utility model claims.
