Abstract

The utility model discloses a roller dryer which comprises a hollow roller into which a hot carrier can be introduced, a scraping knife and a frame, wherein the roller is erected on the frame in a rotatable way and is connected with a transmission device; the scraping knife is fixed on one supporting rod; two ends of the supporting rod are fixed on the frame; a knife edge of the scraping knife is attached on the outer surface of a roller body of the roller and is positioned below the supporting rod; the upper surface of the roller undertakes a feeding device; the lower surface of the knife edge of the scraping knife is provided with a discharging groove; a cover plate is arranged above the discharging groove; one end of the cover plate is connected onto the edge of the discharging groove; the other end of the cover plate leans against the supporting rod; the outer surface of the roller is further provided with a distributing roll; and the distributing roll is erected on the frame in the rotatable way and is connected with the transmission device. The roller dryer not only can prevent a raw material in the discharging groove from being polluted, but also can prevent the raw material from splashing outside to cause the waste of the raw material, thereby optimizing a production environment.

Description

A kind of roller dryer

Technical field

The utility model relates to food drying machinery technical field, especially a kind of roller dryer that passes through the dry tack free slurry of roller.

Background technology

In numerous food drying machinery, roller dryer be through the circular roller that rolls with heat conducting mode, fluid foods that is attached to cylinder body outer wall or slurry are carried out dry a kind of continuous drying equipment; It has thermal efficiency height, and thermograde is big, and the high advantage of material film surface evaporation intensity is specially adapted to the drying that the highly viscous slurry material perhaps contains the more material of solid content.

Existing roller dryer mainly includes the drying roller of one or two hollows and is attached to roller surface scrapes the doctor blade device of getting dried material; The slurry that is dried when dry is attached to the roller outer surface and with its rotation; Be connected with steam or other heat carriers in the roller of hollow; Roller becomes the film like material with the slurry drying of its outer surface, and the scraper that the film like material is affixed on roller surface scrapes and drops in the blow tank, by conveying auger and disintegrating apparatus its pulverizing is seen off subsequently.

In above-mentioned this roller dryer; Because the cylindrical shell of roller always upwards rotates against the spatula end of scraper; Can there be following defective in this intrinsic operating type, and at first owing to the rolling action of roller cylindrical shell, a little slurry that sticks to the roller outer surface can be thrown out of along with the rolling of cylindrical shell outside the drying machine; Cause wastage of material, also contaminated environment; Secondly because the slurry on the cylindrical shell is to be exposed in the air, make the top pollutant fall into contaminated feedstock in the raw material easily.

The utility model content

The technical problem that the utility model will solve provides a kind of roller dryer, not only can prevent that the raw material of blow tank is contaminated but also can prevent that raw material from spattering outward to cause wastage of material, the optimization production environment.

For achieving the above object, the technical scheme of the utility model is: a kind of roller dryer comprises that hollow can lead to the roller of heat carrier, scraper, frame; Roller is set up on the frame with rotating mode and connects transmission device, and scraper is fixed on the support bar, and the two ends of support bar are fixed on the frame; The edge of a knife of scraper is affixed on the barrel outer surface of roller and is in the below of support bar; Accept feed arrangement above the roller, set out hopper below the edge of a knife of scraper, the top of blow tank is provided with cover plate; One end of cover plate is connected on the edge of blow tank, and the other end of cover plate leans against on the support bar.

Further improve; One row's clamping screw and is set on the described support bar teases and ridicule whole screw; Clamping screw is fixed on scraper on the support bar, and the adjustment screw withstands on the angle that is used to adjust scraper on the scraper, makes the angle shovel that the edge of a knife of scraper can be preferable scrape the material on the roller.

Further improve, also be provided with distribute roll on the described roller outer surface, distribute roll is set up on the frame with rotating mode and connects transmission device; On the roller outer surface many distribute rolls can be set simultaneously, can make the more even distribution of slurry like this at the roller outer surface.

Be designed to three and be arranged side by side to described cover plate, each cover plate is connected through folding with the edge of blow tank, conveniently stirs cover plate, observes the operation conditions of each parts.

After adopting said structure; Because of the edge of a knife of scraper is affixed on the barrel outer surface of roller and is in the below of support bar, accept feed arrangement above the roller, set out hopper below the scraper edge of a knife; The top of blow tank is provided with cover plate; One end of cover plate is connected on the edge of blow tank, and the other end of cover plate leans against on the support bar, and cover plate just can play the effect of blocking like this; Splash out on the roller cylindrical shell a spot of slurry or film like material will be blocked and fall in the blow tank by cover plate, reduces the waste of raw material to greatest extent; Simultaneously,, also can avoid outside pollutant to get into the blow tank contaminated feedstock, improve the product cleanliness factor, the optimization production environment because blocking of cover plate arranged.

Fig. 2 is that the utility model roller and adjacent component position concern sketch map;

Fig. 3 is that scraper is connected the broken section enlarged drawing with support bar.

The specific embodiment

Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.

Fig. 1, Fig. 2, shown in Figure 3, a kind of roller dryer comprises that hollow can lead to the roller 1 of heat carrier, scraper 2, frame 3; The mid portion 11 of roller 1 can lead to heat carrier such as steam for hollow; Roller 1 is set up on the frame 3 with rotating mode and connects transmission device 4, and scraper 2 is fixed on the support bar 5, and the two ends of support bar 5 are fixed on the frame 3; The edge of a knife of scraper 2 is affixed on the outer surface of roller 1 cylindrical shell and is in the below of support bar 5; Accept feed arrangement 6 above the roller 1, set out hopper 7 below the edge of a knife of scraper 2, the top of blow tank 7 is provided with cover plate 8; One end of cover plate 8 is connected on the edge of blow tank 7, and the other end of cover plate 8 leans against on the support bar 5.

One row's clamping screw 51 and can be set on support bar 5 tease and ridicule whole screw 52, clamping screw 51 is fixed on scraper 2 on the support bar 5, and adjustment screw 52 withstands on the angle that is used to adjust scraper 2 on the scraper 2.

Roller 1 outer surface also is provided with distribute roll 9, and distribute roll 9 is set up on the frame 3 with rotating mode and connects transmission device 4, and roller 1 outer surface also can be provided with many distribute rolls 9 simultaneously.

Cover plate 8 can be arranged to three, and each cover plate 8 is connected through folding 81 with the edge of blow tank 7.

The operation principle of the utility model is: roller 1 clockwise rotates; The raw material of pulp-like flow to the surface of roller 1 from feed arrangement 6; Pass through distribute roll 9 again the outer surface of the even cloth of slurry at roller 1, because the centre of roller 1 is connected with steam, the moisture of slurry will evaporate rapidly forms the film like material; Scraper 2 just can scrape the film like material from the outer surface shovel of roller 1; The film like material is just fallen into blow tank 7, and because of the barrier effect of cover plate 8, film like material or a spot of slurry that part is splashed are also fallen into blow tank 7 by stopping of cover plate 8 simultaneously.

Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
