Abstract

The utility model provides a vacuum rake drier which is energy saving, efficient, short time for heating, high efficiency in production and stable in product quality. The vacuum rake drier includes a housing, a rake tooth, an agitating shaft and a transmission device, the rake tooth is fixed on the agitating shaft, the agitating shaft is penetrated through the housing and is connected to the transmission device, the housing is provided with a jacket which is provided with a steam inlet and a steam outlet, The vacuum rake drier is characterized in that the agitating shaft is a hollow pipe and the external end part of the agitating shaft is provided with a steam inlet and a steam outlet.

Description

A kind of vacuum rake style drier

(1) technical field

The utility model relates to the dry materials apparatus field, is specially a kind of vacuum rake style drier.

(2) background technology

Vacuum rake style drier is a kind of simple in structure, easy to operate, the traditional drying equipment that applicability is strong, be mainly used in medicine, food, light industry, in the fields such as chemical industry to non-refractory, inflammable, the muddy material of easy oxidation under the high temperature, materials such as plaster pasty materials carry out drying to be handled, the traditional vacuum rake type dryer is when carrying out the drying processing to material, material is entered in the housing by feeding device, under the stirring of the rake teeth of continuous positive and negative rotation, material is walked up and down vertically, the surface that contacts with inner walls is brought in constant renewal in, be subjected to the indirect of housing steam, the even stirring of rake teeth, pulverize, make the moisture content gasification in the material, under the vacuum system effect, the moisture content and the surperficial moisture content of material inside are more advantageously discharged, the moisture content of gasification is through dry collector, wet scrubber and condenser are from vacuum pump outlet emptying, but because heating is only the single circulation of surface of shell to be heated by steam (hot water), material is heated in the surface of shell contact along with stirring constantly, making material the inside moisture be heated to vaporize contacts, surface of shell is single to be provided because heating just has only, it is longer so just to cause temperature to be delivered to the whole material time, production efficiency is low, the electricity and the energy of vapour be relative just expend very big, and because temperature source is on the surface of housing, has only single thermal cycle, being penetrated into material middle temperature and housing wall temperature differs greatly, seriously exist material to amass the piece phenomenon on middle shaft and the rake teeth, difficult drop-off, product quality are unstable because caking is arranged.

(3) summary of the invention

At the problems referred to above, the utility model provides a kind of vacuum rake style drier, its efficient energy-saving, and heat time heating time is short, production efficiency height, constant product quality.

Its technical scheme is such: it comprises housing, rake teeth, shaft, transmission device, described rake teeth is fixed on the described shaft, described shaft is through described housing, described shaft is connected with described transmission device, described housing is provided with chuck, described chuck is provided with steam inlet and steam (vapor) outlet, it is characterized in that: described shaft is a hollow pipe, and described shaft outer end is equipped with steam inlet and steam (vapor) outlet.

It is further characterized in that: described rake teeth is a hollow pipe, described shaft and described rake teeth internal communication.

Use the utility model that material is carried out drying, its beneficial effect is: it adopts housing, shaft to heat simultaneously, makes the process-cycle obviously reduce, improved production efficiency greatly, reduced energy consumption, and rake teeth is also made thermal source, further improve production efficiency, reduced energy consumption; Again because rake teeth and shaft are heating sources, there is not buildup to become the phenomenon of piece on shaft and the rake teeth, make product quality obviously improve.

(4) description of drawings

The structural representation that Fig. 1 looks for the utility model master;

Fig. 2 is that the A-A of Fig. 1 is to cutaway view.

(5) specific embodiment

See Fig. 1, Fig. 2, the utility model comprises housing 1, rake teeth 2, shaft 5, transmission device 7, rake teeth 2 is fixed on the shaft 5, shaft 5 is through housing 1, shaft 5 is connected with transmission device 7, housing 1 is provided with chuck, and shaft 5 is a hollow pipe with rake teeth 2, shaft 5 and rake teeth 2 internal communication; Shaft 5 outer ends are equipped with steam inlet 9 and steam (vapor) outlet 10.Among the figure, the 3rd, drawing mechanism, the 4th, feeding device, 6 is sealing device, and 8 for pulverizing rod, and 11 is chuck, and 12 is the jacket steam air intake, and 13 is vacuum port, and 14 is the jacket steam venthole.Wherein feeding device 4, drawing mechanism 3 are separately positioned on the above and below of housing 1; Pulverize rod 8 and be placed in the housing, place one between per two rake teeths 2 and pulverize rod 8.

During the utility model work, material enters drier from the feeding device 4 of 1 crown center of shell, transmission device 7 drives shaft 5 rotations, rake teeth 2 rotates along with the rotation of shaft, driving material walks up and down vertically, the chuck 11 of housing 1 outside, all be connected with steam in shaft 5 and the rake teeth 2, steam in shaft 5 and the rake teeth 2 enters from the steam inlet 9 on the shaft 5, material in the process of constantly axially walking up and down with housing 1 inwall, rake teeth 2 periphery walls and the contact of shaft 5 outer walls, be subjected to the indirect of steam (hot water), the even stirring of rake teeth 2, pulverize the pulverizing of rod 8, moisture content in the material is gasified rapidly, under the effect of vacuum system, make be dried material internal moisture and the more favourable discharge of surperficial moisture content, the moisture content of gasification is through dry collector, wet scrubber, condenser is from vacuum pump outlet 13 emptying.

Claims

1. vacuum rake style drier, it comprises housing, rake teeth, shaft, transmission device, described rake teeth is fixed on the described shaft, described shaft is through described housing, described shaft is connected with described transmission device, and described housing is provided with chuck, and described chuck is provided with steam inlet and steam (vapor) outlet, it is characterized in that: described shaft is a hollow pipe, and described shaft outer end is equipped with steam inlet and steam (vapor) outlet.
