Abstract

The utility model relates to a turntable concentrating machine, comprising a hollow turnable shaft, a hollow turntable disc, a receiving hopper with a scraper, a collecting tank, a feeding tube and a circulating pump. The subtle solution is sprayed to the hollow turntable disc through the feeding tube, the hollow turntable disc heated by the steam is turned counterclockwise, the subtle solution on the surface of the turntable disc is evaporated and concentrated, and the concentrated product is scraped when passing through the scraper to flow into the hopper 1 and the collecting tank and is discharged from a discharging tube. Compared with the existing opened evaporating pot with a clamping cover, the heating area is increased 4 to 5 times. The utility model can be continuously operated under the vacuum sealed condition; the utility model conforms to the productive standard for the medicines and the foods; the utility model is suitable for evaporating and concentrating various products with high viscosity.

Description

Turntable evaporate concentrate machine

The utility model relates to a kind of rotating disc type Steam Heating concentrator, belongs to technical field of heat exchange, is applicable to the evaporation and concentration of various high viscosity solutions.

At present, arrive tooth after viscosity as Chinese medicine leachate evaporation and concentration in multi-effect evaporator, just can't in multi-effect evaporator, continue again to concentrate, can only move in the uncovered evaporation boiler of band heating jacket, evaporation and concentration is to stiff medicinal extract under condition of normal pressure, but utilize this unlimited pot evaporation and concentration medical product quality seldom to arrive assurance, and incompatible modernized pharmaceutical production standard production requirement.

The purpose of this utility model is to provide a kind of according to the needs of producing reality can heat with saturated vapor, and heating surface (area) (HS is big, compact conformation, can under the airtight vacuum condition, carry out the rotating disc type concentrator that thin film evaporation concentrates continuously to medicine and food.

The technical solution of the utility model is: it comprises housing, hollow rotating shaft, hollow rotating disk, the hopper of band scraper, circulating pump, feed pipe, material collecting tank, discharge nozzle, exhaust outlet, motor and reductor etc., the hollow rotating disk of polylith is enclosed within on the hollow rotating shaft by the dish cover edge of fixedlying connected with it, hollow rotating shaft and condensed water discharge pipe form steam inlet passage and condensation-water drain passage, a plurality of dish covers that mutual series connection is arranged on the hollow rotating shaft, each dish cover is provided with eyelet, so that putting eyelet through dish with water vapour again through the steam inlet passage of hollow rotating shaft, heating enters into hollow rotating disk, condensed water also thus eyelet enter in the hollow rotating shaft and discharge by condensed water discharge pipe again, every rotating disk heating and the center line below is provided with the feed pipe of slot, be equipped with a discharge nozzle near lower housing portion, the one end is communicated with material collecting tank, the hopper contract of a plurality of band scrapers is gone between the hollow rotating disk, and the scraper that inserts in the hopper chute utilizes spring force pressure on the face of rotating disk.Its operation principle is as follows; thin solution sprays on hollow turntable surface through the slot of feed pipe; counterclockwise rotated by steam-heated rotating disk; rotate that weak solution is evaporated concentrated on the transfer card; concentrating degree can realize by regulating the rotating shaft rotating speed, and when the rotating disk card was passed through scraper, the product that has been concentrated was scraped and flows into hopper; be pooled to material collecting tank again, discharge through discharge nozzle in rotation.

The utility model embodiment is described further in conjunction with the accompanying drawings.

Fig. 1 is a rotating disc type concentrator structure chart;

Fig. 2 is rotating disk and hollow shaft structure figure;

Fig. 3 is band scraper hopper structure chart;

Fig. 4 is " I " node enlarged drawing;

Fig. 5 is rotating disk and band scraper hopper structure A-A sectional drawing;

Fig. 6 is " II " node enlarged drawing.

By shown in Figure 1, the rotating disc type concentrator is by the housing of anti-negative pressure the 1, hollow rotating disk 2, the hopper 3 of band scraper, material collecting tank 4, discharge nozzle 5, feed pipe 6, hollow rotating shaft 7, loam cake 8, exhaust outlet 9, condensed water discharge pipe 10, circulating pump 17, circulation fluid exports 18 compositions such as grade, by shown in Figure 1, hollow rotating disk 2 is provided with reinforcement 11 and strengthening nail 12, by Fig. 2 and shown in Figure 3, the hollow rotating disk 2 of polylith is enclosed within on the hollow rotating shaft 7 by dish cover 13 edges, hollow rotating disk 2 is to be welded on the dish cover 13, dish cover 13 mat positioning keys are fixed on the hollow rotating shaft 7, drive rotating disk 2 rotations by rotating shaft 7, hollow rotating shaft 7 and condensed water discharge pipe 10 form steam inlet passage a and condensation-water drain passage b, the series connection of polylith dish cover, the one end abuts against the retainer ring that is welded in the rotating shaft 7, other end nut screwing clamping.Each dish cover is provided with eyelet 14, water vapour enters hollow rotating disk 2 Heating rotary-discs through eyelet 14 again through steam inlet passage a, condensed water also enters hollow rotating shaft 7 by eyelet 14 and is discharged by condensation-water drain passage b, every rotating disk 2 heating surface center lines below is provided with a feed pipe 6 that has slot, being near housing bottom has a discharge nozzle 5 and is communicated with material collecting tank 4, by Fig. 3, Fig. 4, shown in Figure 5, a plurality of hopper contracts that have scraper 16 are gone between the hollow rotating disk 2, scraper 16 is inserted in the chute of hopper 3, utilize the rotating disk of defeating 2 surfaces of spring 19, hopper 3 is fixed on the housing 1, hopper tilts from housing 1 direction at center, and concentrated product in time is pooled in the material collecting tank 4.Prevent to leak by Figure 6 shows that, on the contact-making surface of dish cover 13 and rotating shaft 7 and each dish cover 13 two ends all put at " zero " RunddichtringO 15, be used for material side and water vapour side isolating seal.

The utility model and uncovered jacketed evaporation boiler relatively, its heating surface (area) (HS increases by 4～5 times, and can continued operation under the vacuum tightness condition, meets the production code requirement of medicine and food, is applicable to that various high-viscosity products evaporation and concentration use.
